Abstract
The invention relates to a guiding pillar structure used for a punching die. The guiding pillar structure comprises a male die fixing plate, a discharging plate, a female die fixing plate and a guiding pillar. The discharging plate is installed between the male die fixing plate and the female die fixing plate, the guiding pillar is installed in a guiding sleeve of a guiding pillar hole, an elastic ejecting pin is installed on one side of the top end of the guiding pillar, the bottom end of the elastic ejecting pin is connected with a supporting plate, and the bottom end of the supporting plate is connected with a spring. An air hole is formed in one side of the discharging plate, and one end of the air hole is connected with an air inlet tube. The air hole formed in one side of the discharging plate is communicated with compressed air so that negative pressure can be generated at a leakage opening to suck a punched part or waste downwards; the elastic ejecting pin is installed at the eccentric position of the top end of the guiding pillar so that elasticity can be used for preventing the punched part or waste from rising back.
Description
Technical field
The present invention relates to mold parts field, particularly relate to a kind of diel guide pillar structure.
Background technology
Cold punching technology is a kind of cutting highly efficient in productivity, few or the advanced processing method without cutting, all has a lot of advantages in economy and technical elements.It is easy and simple to handle, is convenient to realize mechanization and automation, is suitable for the production of part more in enormous quantities, and its goods generally do not need to make further machining, and dimensional accuracy and interchangeability are also all relatively good.So it occupies very consequence in the industry such as aviation, automobile, tractor, electrical equipment and electrical, precision instrumentation.In the middle of punching production, diel is as the concrete executing means of Sheet Metal Forming Technology, and natural attention, in fact, the design level of punching die structure and the accuracy of manufacture are the keys ensureing stamped part quality.
Guide pillar guarantees that mould carries out the movable director element guiding mold stroke to locate accurately for combinationally using with assembly in diel, and guide pin bushing guide pillar together constitutes the guiding mechanism of mould, and guide pillar slides and leads in guide pin bushing.In high speed stamping is produced, the rise out of control of stamping and waste material causes serious adverse consequences.The reason of bringing out this phenomenon has a lot, except the inducement increased the weight of in the micro-magnetization of high speed stamping lower punch head, such as resonate with punch press, that lubricating oil is feeding-up or too much, punch enters die be excessively shallow, and gap between punch and die is uneven or punch profile design unreasonable etc. may be all the immediate cause causing stamping or waste material rise out of control.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of diel guide pillar structure.
The present invention is achieved through the following technical solutions:
A kind of diel guide pillar structure, comprise punch retainer, stripper, die block, guide pillar, described stripper is arranged between punch retainer and die block, guide pillar is arranged in the guide pin bushing in guide pillar hole, elasticity jigger pin is equipped with in the side, top of described guide pillar, and the bottom of described elasticity jigger pin connects gripper shoe, and the bottom of described gripper shoe is connected with spring; Offer pore in the side of stripper, one end of described pore connects air inlet pipe.
As the preferred technical solution of the present invention, described gripper shoe and spring are installed in the cavity of guide pillar.
As the preferred technical solution of the present invention, described air inlet pipe is arranged in pore by screw thread, and by adjusting nut adjusting tightness, its air-tightness is met the demands.
As the preferred technical solution of the present invention, the axial line of described guide pillar hole, guide pillar, guide pin bushing is on same straight line.
Compared with prior art, the invention has the beneficial effects as follows: the present invention offers pore in the side of stripper, connect compressed air, make leakage material mouth place produce suction function, inhale under stamping or waste material; By being equiped with elasticity jigger pin at the eccentric position on guide pillar top, elastic force can be utilized to prevent stamping or scraps rising back.
