Reasons and solutions for high vibration of high-speed precision punch press
1. Punch bed reasons
Because the punch press structure has problems, the punch head is bad, the bed or punch press base is unbalanced, and the fasteners such as the connecting bolts are loose. The punch press equipment is aging, and the mechanical parts are seriously worn. The body and the slider are welded by steel plates. The collision and friction between the slider, the mold, and the workpiece of the punch press will cause the vibration of the base and the body of the punch press. The structure and processing accuracy of the steel plate directly affect the strength and rigidity of the body, and the movement stability of the punch press is affected. The unbalanced high-speed punch press is prone to large-scale vibration.
2. Mold reasons
Poor mold, mold imbalance, mold surface may be severely worn, or the uneven phenomenon is very obvious, resulting in uneven bearing capacity at various positions in the stamping process and causing vibration.
3. Workpiece material reasons
Uneven material stacking, too high material hardness, high material brittleness, unbalanced workpieces, poor surface elasticity, poor quality or unevenness of the material.
4. Foundation problems
The foundation is not compacted enough, and the foundation cracks and becomes loose easily. The high-speed punch press will generate huge vibration and impact force during the punching process. The foundation is not enough to support the pressure generated by the punch press at high speed, and the equipment will shake during operation.
Reasons and solutions for high vibration of high-speed precision punch press
Measure 1: Optimize the punching process, control system and mechanical structure of the fuselage. Adjust the punching parameters, increase the stroke, reduce the instantaneous process force of material separation, control the speed and pressure control of the slider, and the impact vibration of the slider will be reduced. Install sensors and improve the control system to monitor the vibration of the punch press during punching and make appropriate adjustments. Improve the accuracy and structural strength of components such as the slider, and use high-strength and low elastic modulus materials to manufacture the equipment structure.
Measure 2: Use suitable shock absorbers. Ordinary punching machines generally use rubber shock absorbers, while high-speed punching machines can use rubber shock absorbers, air cushion shock absorbers, and spring damping shock absorbers. In addition to spring shock absorbers and rubber shock absorbers, there are other types of shock absorbing products, such as film air-floating shock absorbers, air cushion shock absorbers, wire rope shock absorbers, etc. of various specifications and models. If there is a need, you can also consult professional companies, which can generally detect vibration on site and provide shock absorption technical services.
Measure 3: Choose materials with good quality, smooth surface and high processing precision during processing. For example, High-speed press machine stamping intelligent door lock clamp AA battery clamp for various remote controls of home appliances, we can choose stainless steel metal coils for materials.
Measure 4: Adjust the tightness and lubrication conditions of the punching machine.
Measure 5: A solid and compact concrete site should be selected to place the punching machine, and the geological environment of the site also needs to have certain anti-corrosion and anti-moisture properties.
Through the two-part explanation, everyone can have a brief understanding of the reasons and solutions for high vibration of high-speed precision punch press.
