Power heads method of identifying good or bad quality

Abstract: Power head is machine tool specialist machine main parts, the production stability of the power head is the key, so the power head quality good or bad is very important.
  Identify power head quality good or bad standard is mainly from the following aspects:
  First, power head core shaft is most critical, keep rotating and reciprocating motion, but also by the force of the work, so must use good material, must strengthen the hard processing, otherwise quite easy to wear, causes the processing effect degradation, Power head jitter increases, and will not be able to process.
  Second, bearing portion, directly sets the core shaft periphery, when the core shaft reciprocating motion, also wants to rotate at the same time, bearings to withstand the pressure of work are also great, the quality is quite good.
  Third, moving parts, drilling head generally has cylinder, oil cylinder and screw, mainly is undertaking the core shaft reciprocates, and mainly is seal better.
  Fourth, shell, mainly production of compact structure, gap is too big, prone to error.
  Fifth, the good quality of the belt wheel, the effect will be relatively stable, not easy to swing, driving force is strong.
  Sixth, motor, of course the quality better, speed, and torque is better.
  Seventh, cutting tools, this is the loss is tasted; choose according to their own conditions.
  Power head is machine tool specialist machine main parts, power head production stability is the key, without installing the handle, power head accurate precision of the spindle is bent at the nuclear power head, power had generally in the 0.5 wire. So the knife handle has a great influence in the power head processing. A handle of the heat treatment, standard size, gripping capabilities have an impact on the workpiece. The wear degree also has the very big difference. So when choosing power head, at the same time also should pay attention to the knife handle of the choice.

What is the characteristic of a punch press forging?

Abstract: Punch press is the forging equipment, cold stamping machine tool, but forging characteristic a lot of people are not very clear, what are the characteristics of forging, specifically how to realize the forging?
As is known to all, punch press is the forging equipment, cold stamping machine tool, but forging characteristic a lot of people is not very clear, what are the characteristics of forging, specifically how to realize the forging? Here for your analysis:
The so-called forging is can change the mental organization, improve the metal properties. After hot forging ingot casting, original as-cast loose, porous, micro-crack etc compaction or welding; The original dendritic crystal were broken, make grain finer; At the same time, change the original carbide segregation and uneven distribution, uniform organization, thereby gaining internal dense, uniform and fine, good comprehensive performance, use reliable forgings. Forgings after hot forging deformation, metal are fibrous tissue; after the cold forging deformation, metal crystal was orderly.
Punch press forging is to make the metal plastic flow and work piece of desired shape. Metal plastic flow generated by external forces after the volume unchanged, and metal is always flowing to least resistance section. Production, often based on these rules control the workpiece shape, realizes the upsetting long pull, reaming, the bending, deep drawing etc deformation.

  Many different kinds of damping, its working principle is roughly similar to, the following by the road, to introduce the working principle of the air damper under: air damper is a kind of use of air viscosity damping device. Different from general shock absorber is its damping medium is air, which can overcome the liquid viscous damping some faults. Because of its high compressibility of the air, so can bear larger displacement. The air holding in the flexible corrugated box, can provide damping in vertical and horizontal direction. Relative to the liquid, air viscosity changing with temperature is not big, therefore with stable performance. But in too high or too low temperatures, corrugated box changes the elasticity of rubber.
