Description

A kind of flange rotary body straightening die pick-off unit

Technical field

The utility model belongs to mechanical cool-working technology field, and in particular to a kind of flange rotary body straightening die pickup dress Put.

Background technology

In the production of metal plate cold stamping (punching, bending, stretching), basic part that punching press obtains, its shape and size Precision and minimum radius of corner are by limit.When element precision requires high, radius of corner is small, after forming process Basic part need to use correcting process, and qualified part is obtained with final guarantee.Correction pickup is instigated by various basic shapings Stamping parts after process produces little plastic deformation again, to reach the stamping parts of the dimensional accuracy of technological requirement and shape, school After the completion of direct action, pass through the smoothly demoulding taking-up from punch-pin or cavity plate by stamping parts of the device for discharging in mould.

After the completion of being corrected for flanged tensioning member, existing way has two kinds in a mold for it：First, stay on punch-pin； Another kind is stayed in cavity plate.Part is stayed on cavity plate first, generally utilizes the bar of beating of part of the upper die in mould to promote back pieces device, Part is exited in cavity plate；Secondly part is stayed on punch-pin, usually using homemade buffer gear on punch press, passes through mould Unloading bolt, push rod, the stripper of middle part of the lower die, part is ejected from punch-pin.The correction of traditional flange rotary body takes Part is mould by buffer gear in punching apparatus, jacks up the device for discharging in mould, part is taken out.When no slow on punch press During punch mechanism, part is trapped in punch-pin, it is difficult to take out part, need to consider to design on Correction Die can move back from cavity plate Go out a kind of design structure that part and can ejects part from punch-pin.

Utility model content

The utility model is in order to solve the above technical problems, provide a kind of flange rotary body straightening die pick-off unit.

Technical scheme is used by the utility model：A kind of flange rotary body straightening die pick-off unit, including upper mould and Lower mould, part of the lower die：Lower template, unloading bolt, spring, guide plate, punch-pin, clamping plate, stripper, screw, straight pin；Upper mold portion Point：Screw, pin, cavity plate, back pieces device, fixed plate, backing plate, cope plate, die shank, beat bar, hook component；Hook component includes hook Son, bearing, spring leaf, pin, screw.Upper mould is integrally fixed on punching apparatus sliding block, and lower mould is mounted in the work of punching apparatus Make on platform.

The part of the lower die convex mould is fixed in lower template by mode connects for screw；

The stripper is connected by spring with unloading bolt, is held up part and is oriented to up and down, unloading bolt in punch-pin It is arranged in lower template；

The guide plate is arranged in lower template, passes through screw, pin connection positioning, position skew lower template center；

Cavity plate is arranged on fixed plate lower surface in the part of the upper die, is positioned by screw, cylinder pin connection；

The back pieces device is arranged among fixed plate and cavity plate, is oriented to using fixed plate, back pieces device is moved up and down；

The hook component is arranged on fixed plate both sides, by welding bearing, is fixed in fixed plate；

Two kinds of pins, a kind of pin connects bearing are set on the hook, and another pin stretches out certain at the hook back side Height is engaged with guide plate, drives hook to have the action opened and closed, and hook angle is consistent with guide plate angular configurations 20 °, Require that two flipper guide height H, angle [alpha] and boss height L are completely the same during making；

The dead plate upper end face is arranged on backing plate lower surface, and cope plate is connected to by screw, pin；

Cope plate lower surface is close in the upper surface of the fixed plate, is positioned by screw, pin connection,

The die shank is arranged on cope plate central hole, and interference fits are done with hole.

It is described that straightening die is arranged on punch press mould, and do and mould is debugged.

The startup punching apparatus moves down upper mould, and the cavity plate of mould pushes down workpiece in connection, continues to move to cavity plate To minimum point, hook is entered in the hook and slot of stripper by spring leaf pressure, and part is carrying out school during moment continu to press Just.After the completion of correction, upper mould moves up, and hook has corrected part simultaneously with stripper and moved upwardly together, and pickup starts, Part is slowly deviate from from punch-pin, and when the pin on hook encounters the trapezoid boss of guide plate, hook gradually unclamps discharging The hook and slot of plate, when pin slides into the peak of guide plate trapezoid boss, the completely disengaged stripper of hook, the part being corrected is simultaneously Depart from punch-pin.Pickup process all terminates.

A kind of flange rotary body straightening die pick-off unit of the utility model, is connected using cope plate with fixed plate, bearing weldering It is connected on fixed plate both sides, hook is assembled on bearing by straight pin, spring leaf is fixed on cope plate by screw Both sides are simultaneously consistent with bearing installation direction, are arranged in lower template using guide plate, are connected to by screw, straight pin in lower template, The position processing hook and slot of hook, spring compression hook portions before work, the working face category nature shape of hook are corresponded on stripper State, the pin being fixed on hook during work slides along guide plate trapezoid boss drives hook to be driven, and hook is into stripper In hook and slot, hook stripper and move up, reach pickup.This apparatus structure is simple, and pickup is accurately convenient and reliable.

Embodiment

The utility model is described further below in conjunction with the accompanying drawings：

A kind of method of flange rotary body straightening die pickup of the utility model, main implementation process are：Mould installion is being rushed Bed and to good mould after, will be put into by workpiece 21 in lower mould, and be allowed to conform to a conventional pattern in the outer wall upper surface of punch-pin 9, workpiecc lug following table Face is touched on stripper 8；Stripper 8 is jacked up by the spring 2 being enclosed on unloading bolt 3.Start punching apparatus by upper mould Start to move down, cavity plate 10 is close to workpiece 21 and is conducted into punch-pin 9, rapid workpiece pressing 21, fixes in the process Hook component on plate 16 moves down with upper mould；Under the pressure effect of spring leaf 14, the pin 22 that is fixed on hook 11 Lowest part is slided into from the highest point on the boss of guide plate 4, continues to move down, cavity plate 10 is adjacent to workpiece 21 completely, presses stripper 8, now hook 11, which is entered in the hook and slot of stripper 8, hooks stripper 8, and punch-pin 9, cavity plate 10 are right during moment continu to press Workpiece 21 is being corrected, after the completion of correction.Upper mould is moved up, and bar 20 is made in upper mould and encounters back pieces device 18, back pieces device 18 is suitable When along cavity plate 10 move downward top arrive the bottom of workpiece 21, workpiece 21 is ejected into cavity plate 10, workpiece is just enclosed on punch-pin 9.It is same in this When on modular belt hook 11, stripper 8 and corrected workpiece and move upwardly together, pickup starts, workpiece from punch-pin 9 slowly to Upper movement, when the pin 22 on hook 11 encounters the trapezoid boss of guide plate 4, hook 11 progressively disengages the groove of stripper 8, Slowly it is flared out, when pin 22 slides into the peak of the trapezoid boss of guide plate 4, the completely disengaged discharging of working face of hook 11 The hook and slot of plate 8, workpiece depart from punch-pin 9 simultaneously, i.e. pickup process is fully completed.

Mold work state, see Fig. 1 left sides,

Hook departs from stripper and returns to nature, sees on the right of Fig. 1,

The scope of protection of the utility model is not limited to the technical scheme disclosed in specific embodiment part.
