Abstract
The invention provides a punch forming device for plates with dense blind holes. The punch forming device comprises a punch press, and is characterized in that the punch press comprises two press bodies, a female die is arranged between the two press bodies, a surface of a press body, which are approximate to one side of the female die, is covered by guide rails, dense blind hole positioners and guide rails are sequentially arranged on the surface of the other press body, which is approximate to the other side of the female die, from near to far, concave-convex surfaces which are consistent with a male die and the female die are arranged on surfaces of the positioners, the male die matched with the female die is arranged above the female die, and optional and adjacent three concave surfaces or convex surfaces on each of the female die and the male die are arrayed to form an equilateral triangle. The heights of the dense blind hole positioners are identical to those of the guide rails on the other side of the female die and the male die and are larger than the heights of the guide rails on the same side with the dense blind hole positioners, and the height differences of the dense blind hole positioners and the guide rails on the same side with the dense blind hole positioners are equal to the depths of the concave-convex surfaces. By the aid of the punch forming device, materials of a blind-hole forming and squeezing portion can be effectively prevented from gathering to hole bridges, so that the thickness difference between each stretched blind hole and the corresponding thickness-accumulating hole bridge is increased. In addition, the punch forming device has the advantages that high-quality continuous production and processing can be realized, the punch forming device is low in processing cost and easy and convenient to operate, the plates can be produced in large scale, the dies are maintained and repaired conveniently and easily, and links with requirements on controlling a production environment are few.
Description
Technical field
The present invention discloses a kind of punch forming device, especially a kind of on cold-reduced sheet surface punch forming gather, the close blind hole plate punch forming device of the truncated cone-shaped pit of round-corner transition, belong to field of machining.
Background technology
At the close blind hole plate of cold-reduced sheet Surface Machining, adopt metal die and die at present in hydraulic press compression moulding.When the close blind hole little, need use the forcing press of hundreds of ton in cold-reduced sheet Surface Machining aperture; Require the precision of the close blind hole mould of processing higher, when punch and die calibration, deviation is arranged slightly, will form the accumulated error of close blind hole; And can the material of close blind hole moulding crimping section be gathered bridge; Form the thickness difference of blind hole and bridge, simultaneously, because blind hole periphery tensile stress is inhomogeneous; Even tear and drawing crack, cause quality unstable and be difficult to control, equipment and the frock investment is excessive, yield rate is low, product cost increases.
And utilize the material behavior of cold-reduced sheet; Use has certain potential energy; Rely on the impact kinetic energy of impulse force, knock nail at cold-reduced sheet Surface Machining moulding pit as hammer, than reducing greatly at the employed power of cold-reduced sheet surface by utilizing pressure forming slowly.
Summary of the invention
For solving the aforementioned problems in the prior, the present invention provides a kind of close blind hole plate punch forming device, and the present invention can realize high-quality continuous production and processing; Easy and simple to handle; Discharging is simple, and cost of investment is low, can accomplish scale production easily; The maintenance of mould and easy row easy to maintenance, the link that production environment need be controlled is few.
The present invention realizes through following technical scheme:
A kind of close blind hole plate punch forming device; Comprise punch press, it is characterized in that lathe bed is divided into two parts, be provided with die between two lathe beds; The bed surface of die one side is gone up by guide rail and is covered, and sets gradually close blind hole positioning body and guide rail on the lathe bed surface of die opposite side from the near to the remote; The positioning body surface is provided with the male and fomale(M&F) consistent with punch and die; The die top is provided with the punch suitable with it; On die and the punch, arbitrarily adjacent three concave surfaces or convex surface all are triangular arranged.Accordingly, in the close blind hole that on by cold-reduced sheet, obtains, three adjacent close blind holes are triangular arranged arbitrarily, thereby each bridge is consistent.
Said close blind hole positioning body is identical with the rail height of concavo-convex mould opposite side, is higher than the guide rail with its homonymy, and difference in height is the degree of depth of male and fomale(M&F).
In the degree of depth less than 1/2nd close blind hole radiuses; And close blind hole has round-corner transition and uses under the condition of lubricating oil, and the sheet metal of the close blind hole of moulding can not be stuck on the die, discharging rapidly; And push ahead or serial, rely on the close blind hole of the part location of moulding then.
Said punch press is the crank connecting link punch press.Supporting punch press, the impact kinetic energy of dependence impulse force is realized the close blind hole processing of the corresponding forming surface of punch and die rapidly, the workbench of location is moved and limits in supporting use, can realize accurate, continuous production and processing.
Concave surface and convex surface use 60 degree angles, are the punch and the die of the quincunx unit of being arranged as layout, supporting crank connecting link punch press, the impact kinetic energy of dependence impulse force; Realize that rapidly the punch and the close blind hole of the corresponding forming surface of die process, less than 1/2nd close blind hole radiuses, and close blind hole has round-corner transition and uses under the condition of lubricating oil in the degree of depth; The sheet metal of the close blind hole of moulding can not be stuck on the die, discharging rapidly, and push ahead or serial; Rely on the close blind hole of the part location of moulding then; The workbench of location is moved and limits in supporting use, just can realize accurate, continuous production and processing, and the accumulated error of close blind hole is reduced significantly; Avoid the material of close blind hole moulding crimping section is gathered bridge, cause thickness of structure to increase, and thickness reduces on the blind hole structure that stretches, thickness of slab is inconsistent on the generation overall structure.
Die upper surface according to lathe bed of the present invention is parallel with workbench, by the beat paces formula charging with punch on the workbench surface of the cold-reduced sheet of punching out.
The invention has the beneficial effects as follows: utilize stretching and ductility of cold-reduced sheet, realize high-quality continuous production and processing, and the processing cost of punch and die is low; Corollary equipment crank connecting link operating punch machine is easy; Device for discharging is simple, and cost of investment is low, can accomplish scale production easily; The maintenance of mould and easy row easy to maintenance, the link that production environment need be controlled is few.
