Abstract
The invention relates to the field of stamping dies, in particular to a pneumatic type time-delay mechanism for stamping in the stamping dies. The pneumatic type time-delay mechanism structurally comprises an air cylinder, a sliding block and a guide board; the air cylinder is arranged on a blank holder, and a piston rod on the end portion of the air cylinder is connected with the sliding block through threads; the sliding block is fixed and guided to slide by the guide board, and the lower end face of the sliding block is a sliding face and slides in parallel with the guide face of the blank holder. The pneumatic type time-delay mechanism resolves the problem that after a die is opened, an upper die pressure plate and the lower die blank holder crush a workpiece because of reset movement. The pneumatic type time-delay mechanism is simple in structure, assembly of the die does not need any auxiliary tools, operation and debugging are easy, labor intensity of workers is lowered, production efficiency is improved by about 10% on year-on-year basis, and the pneumatic type time-delay mechanism has good economical efficiency and practicality.
Description
Technical field
The present invention relates to the diel field, particularly be a kind of pneumatic type time-delay mechanism in diel.
Background technology
Along with the development of automobile industry and the day by day maturation of Sheet Metal Forming Technology, the shape of product becomes increasingly complex, and required precision improves constantly, and in existing product, usually has some need in drawing work, realize special material pressing mould structure.This kind of structure need to be appended holding pad on die, for preventing it, walks to expect the wrinkling folded material phenomenon of too fast appearance.Through facts have proved, mould is after on earth, along with the lathe top shoe is opened, the patrix holding pad is because the relation of stroke is pressed on product always, remain static comparatively speaking always, and the counterdie blank holder is to do along with opening of slide block to move upward, the process part processing that work is completed directly is squeezed on the patrix holding pad, and product is damaged by pressure.In the die sinking process, the release simultaneously of the stroke of holding pad and blank holder can make product damage by pressure and can't normally take out.Therefore, a kind of technical scheme of exigence solves the problems referred to above.
The number of patent application that the applicant has disclosed: 201110241009.8, patent name is " a kind of punching mold time delay falling mechanism ", this mechanism is mechanical structure.The present invention provides another kind of solution for addressing the above problem.
Summary of the invention
The present invention is directed to resetting of upper and lower holding pad and damage the technical scheme that the technical problem of product proposes a kind of solution by pressure.
Concrete technical scheme of the present invention is: a kind of punching press pneumatic type mold time delay falling mechanism, and this structure comprises: cylinder, slide block and guide plate; Described cylinder is arranged on blank holder, and its end piston rod is connected with slide block by screw thread; The fixing slide guide of guide plate for described slide block, this slide block lower surface be sliding surface and with blank holder spigot surface parallel sliding.
The invention has the beneficial effects as follows: solved the reseting movement of patrix holding pad and counterdie blank holder after the mould die sinking and the situation of damaging product by pressure, this mechanism is pneumatic type mechanism, this is simple in structure, upper mould need not be installed any aid, debugging easy to operate, reduced workman's labour intensity, improved production efficiency, increase on year-on-year basis approximately 10%, there is good economy and practicality.

The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
The invention provides a kind of upper holding pad pneumatic type mold time delay falling mechanism, described mold time delay falling mechanism comprises: cylinder 1, slide block 2 and guide plate 3.
Described cylinder 1 is arranged on blank holder 7, by tracheae, with press machine, is connected, and the ejecting and regaining of the turnover control cylinder piston rod by gas circuit, its end piston rod is connected with slide block 2 by screw thread; Described slide block 2 is arranged on blank holder 7, these slide block 2 lower surfaces be sliding surface and with blank holder 7 spigot surface parallel sliding; Described guide plate 3 is fixedly mounted on blank holder 7; This guide plate 3 is slidably matched with slide block 2 both sides and upper stage terrace.
As shown in Figure 1 and Figure 2, time-delay mechanism of the present invention is different from mechanical type wedge time-delay mechanism, this mechanism with cylinder 1 as drive force source, can free control cylinder in the middle of the course of work move back and forth, thereby realize delay function.The time delay that this mechanism also can be used for the counterdie holding pad ejects, and when the time delay for lower holding pad ejects, this mechanism also can be arranged on patrix.
Below the course of work of the present invention is described:
The present invention is in upper bolster 4 and patrix holding pad 5 press down process.As shown in Figure 3, slide block 2 in retracted state, does not affect the normal binder of holding pad 5 due to cylinder 1, and the pressure source of holding pad 5 is the nitrogen spring 6 that is arranged on patrix 4.At this moment upper bolster 4 and blank holder 7 are pushed down Realization of Product and are drawn content, and the pressure source of blank holder 7 is lathe push rod 8, and upper bolster 4 pushes down blank holder 7 until contact die shoe 9, drawing work finishes, mould on earth.In this process, time-delay mechanism moves downward with blank holder 7.Holding pad 5 contact die shoes 9, upper bolster 4 is done and is moved upward relatively.As shown in Figure 2, at mould, on earth during state, holding pad 5 reaches the state that slide block 2 can insert, and the interior lathe inflation of cylinder 3 ejects piston rod, thereby drives slide block 2 to insert below holding pads 5.
As shown in Figure 4, in the mould opening procedure, holding pad 5 remains the relative distance of part height with blank holder 7 under the intervention of slide block 2, and part is not damaged by pressure.Mould continues to open, and blank holder 7 and holding pad 5 strokes discharge complete, and slide block 2 is return under cylinder 3 piston rod withdrawal effects, completes a work period.
The situation that the invention solves the reseting movement of patrix holding pad and counterdie blank holder after the mould die sinking and damage product by pressure, this is simple in structure, upper mould need not be installed any aid, debugging easy to operate, reduced workman's labour intensity, improve production efficiency, increased on year-on-year basis approximately 10%, there is good economy and practicality.
