And utilize the material behavior of cold-reduced sheet, use has certain potential energy, rely on the impact kinetic energy of impulse force, as hammer knocks nail at cold-reduced sheet Surface Machining moulding pit, than utilize the employed power of slowly pressure forming greatly to reduce on the cold-reduced sheet surface.
The utility model content
For solving the aforementioned problems in the prior; the utility model provides a kind of close blind hole plate punch forming device; the utility model can be realized 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 is convenient and easy, and the link that production environment need to be controlled is few.
The utility model is achieved by the following technical solution:
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 upper to be covered by guide rail, sets gradually from the near to the remote close blind hole positioning body and guide rail on the lathe bed surface of die opposite side; The positioning body surface is provided with the male and fomale(M﹠F) consistent with punch and die; The die top arranges the punch suitable with it; On die and the punch, three concave surfaces or the convex surface of arbitrary neighborhood all are triangular arranged.Accordingly, in the close blind hole that is obtained by cold-reduced sheet, three close blind holes of arbitrary neighborhood are triangular arranged, thereby each bridge is consistent.
Described close blind hole positioning body is identical with the rail height of concave-convex mold 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, rapidly discharging, and push ahead or serial, then rely on the close blind hole of the part location of moulding.
Described punch press is the crank connecting link punch press.Supporting punch press, the impact kinetic energy of dependence impulse force is realized rapidly the close blind hole processing of the corresponding forming surface of punch and die, supports the use workbench mobile and that restriction is located, can realize accurate, continuous production and processing.
Concave surface and convex surface use 60 degree angles, the punch and the die that are the quincunx unit of being arranged as layout, crank matched with same connecting rod punch press, rely on the impact kinetic energy of impulse force, realize rapidly the close blind hole processing of the corresponding forming surface of punch and die, 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, the sheet metal of the close blind hole of moulding can not be stuck on the die, rapidly discharging, and push ahead or serial, then rely on the close blind hole of the part location of moulding, support the use workbench mobile and the restriction location, just can realize accurately, continuous production and processing makes the accumulated error decrease of close blind hole; Avoid the material of close blind hole moulding crimping section is gathered bridge, cause the thickness of structure to increase, and thickness reduction 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 utility model is parallel with workbench, the cold-reduced sheet that is punched on the workbench surface with the beat step type charging of punch.
The beneficial effects of the utility model are: 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 is convenient and easy, and the link that production environment need to be controlled is few.
