Presses (including punching machines and hydraulic presses) are general-purpose presses with delicate structures. With a wide range of uses and high production efficiency, presses can be widely used for cutting, punching, dropping, bending, riveting and forming processes. By applying strong pressure to the metal billet to make the metal plastic deformation and fracture to process into parts. The mechanical press is driven by an electric motor through a v-belt to drive a large pulley (usually doubles as a flywheel), which drives the crank slider mechanism through the gears and clutch to make the slider and the convex die go down in a straight line. When the mechanical press is finished forging, the slider travels upward and the clutch is automatically disengaged, while the automatic on the crank shaft is turned on to stop the slider near the upper stop.

Four-column type gas-hydraulic presses
Four-column type pneumatic-hydraulic press
The press is driven by the motor through the transmission mechanism to drive the working mechanism to apply process force to the workpiece. The transmission mechanism is belt drive, gear drive reduction mechanism; the working mechanism is divided into screw mechanism, crank linkage mechanism and hydraulic cylinder.
Presses are divided into three categories: screw presses, crank presses and hydraulic presses. Crank presses are also known as mechanical presses.
Screw presses do not have a fixed lower dead point, for larger die forgings, can be struck several times to form, can be a single hit, continuous hit and inch movement. The striking force is related to the amount of deformation of the workpiece, with small striking force when the deformation is large and large striking force when the deformation is small (such as cold striking). In these respects, it is similar to forging hammer. But its striking force is closed through the frame, so it works smoothly, and the vibration is much smaller than forging hammer, and does not need a large foundation.
The lower part of the press is equipped with forging ejector. The screw press has both the role of die forging hammer, mechanical press and other forging machinery, versatility, can be used for die forging, punching, deep drawing and other processes. In addition, the screw press is simple in structure and easy to manufacture, so it is widely used. [1]

Screw press
Screw press uses screw and nut as transmission mechanism, and relies on screw transmission to transform the forward and reverse rotary motion of flywheel into up and down reciprocating motion of slider. When working, the motor accelerates the flywheel to save energy, while the screw and nut push the slider to move downward. When the slider touches the workpiece, the flywheel is forced to decelerate to a complete stop, and the stored rotational kinetic energy is transformed into impact energy, and the workpiece is struck by the slider to deform it. After the blowing is finished, the motor makes the flywheel reverses and drives the ram up to return to the original position. The specifications of screw presses are expressed in terms of nominal working force.
Crank presses
The crank press is one of the most commonly used cold stamping equipment, used as a working platform for cold stamping dies. Its structure is simple and easy to use. According to the different forms of bed structure, crank presses can be divided into open crank presses or closed crank presses; according to the number of driving linkages, they can be divided into single-point presses or multi-point presses; according to the number of sliders, they can be divided into single-action presses or double-action presses.

Multi-station presses
Multi-station press is an advanced press equipment, which is an integration of multiple presses, generally consisting of wire head unit, feeding mechanism, press and wire end part. The fastest speed can be 40 times/min or more, which can meet the high speed automatic production. The head unit can be divided into depalletizing unit, magnetic belt, cleaning and oiling equipment, etc.; the feeding mechanism is generally composed of double arms for feeding; the press is generally divided into multi-slider and single-slider, which can be selected according to different needs; the end part of the line is generally composed of conveying belt.
Machinery use edit Podcast
Improper press operation or press die setup is the number one cause of press damage and downtime. Proper training of press operators and die setters will ensure that they follow the correct procedures. This will quickly reduce downtime.
Lubricate the brake spindle at all points of the manipulator before each shift, fill the rod ball head and other areas with an oil gun with the proper amount of 20-30 mechanical oil before each shift, and press the clutch area with an oil gun once a day before each shift. Clean the machine before stopping every shift.
Check the fasteners and make up the missing external parts. Check the clutch and spring, belt. Check the lubrication device of each machine tool. Check the electrical wiring for breakage and aging, and the motor and solenoid for normal. Check the crankshaft guide accuracy and wear. Check the brake, clutch, slider, closing block, closing ring. Check the electrical control part. Inspection and adjustment of machine table coupling bolts.
According to the different machine types and processing requirements of the press, develop targeted and practical safety operating procedures, and conduct the necessary job training and safety education. The use of units and operators must strictly comply with the provisions of the design and manufacturing unit to provide safety instructions and operating procedures, the correct use, maintenance. General safety operation requirements for presses are as follows.
Before moving the equipment, check whether the operating part of the press, clutch and brake are in an effective state, whether the safety guards are intact and working, and whether there are any abnormalities in the crank slider mechanism. Abnormalities found should immediately take the necessary measures, do not run with disease, disassembly and damage to safety devices is strictly prohibited. Before the official operation must be idle test run, to confirm the normal parts before work. Before starting the machine should be cleaned up all unnecessary items on the workbench to prevent driving vibration down to injure people or impact on the switch caused by the sudden start of the slider. The operation must use tools, it is strictly forbidden to reach directly into the mold mouth to take things by hand, and hand tools should not be placed on the mold.
When adjusting the position of the workpiece in the die opening area or uncovering the workpiece stuck in the die, the foot must leave the foot pedal. Multiple people operating the same press should be unified command, clear signal, wait for each other to make a clear answer, and confirm to leave the danger zone before action. The power should be turned off after a sudden power failure or operation, and the manipulator should be restored to clutch neutral and the brake in braking state. Press maintenance, adjustment, and in the installation, adjustment, disassembly of the mold, should be in the machine disconnected energy (such as electricity, gas, liquid), the machine stopped running, and put under the slider reliable support cushion. Machine tool start switch at the hanging sign notice warning.
Machine Maintenance Editorial Podcast
Pay attention to safety
Ensure that the locking/opening process is performed correctly for the safety of maintenance personnel and that the sleeve is placed at the bottom of the travel before performing brake maintenance work. If this is done, there is no need to lock the sleeve.
Maintenance Process
Including press operators in the process of maintaining the press allows them to alert maintenance or management whenever problems arise. They operate the press every day and can more easily hear or see the signs of problems. Just as driving the same car every day makes it possible to notice unusual noises at first glance, so it is for the operator.
Shop floor environmental control
A clean pressure machine allows the operator or maintenance personnel to detect problems as soon as they occur. Leaks, air leaks, breaks, etc., are simple to locate if the press is clean.
Problem Solving
Only a qualified electrical technician should perform electrical wiring maintenance on the press, but you can still check the light bulb on the press control panel for proper operation, and make sure it is working every shift and correctly displays the status of the various operations performed by the press.
Make sure it's balanced
Presses that are precisely balanced work better, so it is best to check them once a year. The pneumatic system, which operates the pneumatic brakes and balancing system, needs to be checked for gas leaks because improper air pressure can affect the performance of the brakes and balancing system, and they control the stopping time of the press, which can put the operator and the equipment in danger if problems occur. In addition, all pneumatic systems have regulators, lubricators and water reservoirs. The water that accumulates in the gas lines should be removed daily.
Improper maintenance of the press lubrication system is also one of the main reasons for press downtime. For a number of reasons, many press operators do not change the screen regularly when operating circulating oil systems with screens. It is important to ensure that the screen is changed at the same time as the oil is changed and that it is changed frequently during the day.
Maintenance Keys
What is the most important aspect of a mechanical press routine maintenance program? The answer is the operator. All press maintenance and problem finding begins with the operator, who is often able to identify press problems early enough to prevent major, ongoing damage to press components. Operators can spot problems by noticing strange noises coming from the press; unusual temperature rises, smoke, debris or metal particles in certain parts; and leaking lines. Each day the operator should ask himself some questions and keep a long-term maintenance record by checking and then recording the answers.

Press Maintenance
Pre-shift maintenance of presses
(1) Check whether the oil pool, oil level and oil mark meet the prescribed standards, and if not, refill oil in time.
(2) Check whether the button is flexible and there is no jamming.
(3) Check whether the motor grounding wire is loose, off or damaged. If there is loose should be tightened, off or damaged should notify the maintenance personnel to deal with.
(4) Check whether the safety guards are complete and reliable.
(5) Check whether the handles are flexible.
(6) Tighten the nuts of the loosened parts.
