Presses (including punch presses and hydraulic presses) are compact and versatile forging presses. With its versatility and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. The parts are machined by plastically deforming and breaking the metal by applying a strong pressure on the metal blank.
It is very necessary to understand the common faults and solutions of some presses. Not only can it solve the problem in time, but it can also increase production efficiency and greatly reduce the cost of production.
Forging machines are the most troublesome problem because they run off the slope. The reason is that the center line is not correct and the feed baffle is not perpendicular to the profile axis. The corresponding treatment method is to re-align the centerline, correct the centerline, correct the deflection direction of the incoming product baffle and correct it. Clutch does not work There is a violent impact when it is disengaged because the working key tension spring of the press machine breaks loose, and the working end of the key is broken or the work key is damaged. Replace tension springs, work keys, press brakes and other major devices to solve the problem solution.
The most common problem with presses is scratching on the surface. Although this does not affect the normal use of the press, the appearance of the problem indicates that there are aspects that need to be adjusted. If the gap is too small, the surface of the press wheel is rough, and the surface of the press wheel is coated. Improperly, the press wheel has a zinc layer. To make corresponding adjustments, re-measure the gap to the right, use the oilstone to smooth the pressing wheel and wait until the oil is smooth.
The press crankshaft bearing heat may be due to the shaft sleeve scraping is not good, poor lubrication, re-striking copper tile, check the lubrication condition; from the bearing out of the oil there is copper swarf is the lack of lubricating oil, lubricating oil is not clean, When it is necessary to check the lubrication condition, disassemble the bearing for cleaning. The guideway cauterization is caused by poor lubrication and poor contact due to the small guideway gap. It is necessary to re-scrape the guide rail, adjust the clearance, and pay attention to lubrication.
When the press is operated, the clutch is not engaged or the clutch cannot be disengaged because the elastic key is too tightly fit. It is necessary to replace the spring and check the combined clearance of the scratch key. When the clutch is disengaged, the slider cannot stop at the top dead center position, which will lead to system failure. The belt tension is not enough, the brake belt is excessively worn, the brake wheel is oil slipping, the brake spring tension is adjusted, the brake is replaced, the brake band is washed with kerosene, and the circumference of the wheel.
Press stripper does not work, the position of bumper is incorrect, adjust the position of the head by hand to turn the flywheel to try and retreat; the connecting rod screw rotates or impacts, the locking device loosens, the rotary locking device; the connecting rod screw ball head in the slider Ball impact, poor contact between the ball head and the ball cover, the cover screw loose scratch ball head, ball pad, tighten the cover screw; press the button (on) does not work power circuit, thermal cut off, check the circuit The system eliminates the fault.

Vegetable/Fruit Grinding Machine
Work Principle:
The machine is fixed by different geometry, the relative rotation of the rotor under high speed rotation, when the material under the weight, air pressure and centrifugal force through adjustable stator clearance, subject to strong shear , Friction, impact force, high-frequency vibration and other complex forces, are effectively broken, dispersed emulsification and mixing, resulting in the ideal product.
