A kind of forming and punching mould

Technical field

This utility model is related to a kind of mould, and in particular to a kind of forming and punching mould.

Background technology

In the course of processing of sheet metal, often it is related to the operation of flanging and restriking after punching, in prior art, generally First it is punched out using one set of die, then reusing special flanging die carries out hole-crimped forming, so on the one hand causes work Skill is complicated, needs the processing that multiple working procedure is carried out to product, not only result in the wave of human resourcess, device resource and space resources Take；Also, product turn-up portion is also can result in during flanging and restriking separately to split, substandard products are caused, and reduces product quality.

Utility model content

The purpose of this utility model is to overcome defect present in prior art, there is provided a kind of forming and punching mould, should Mould structure is simple, easy to operate, can greatly improve production efficiency, reduce production cost, improve product quality.

For achieving the above object, design of the present utility model is as follows：

A kind of forming and punching mould, is made up of upper die and lower die；Wherein, the top of upper mould is upper die plate, in upper die plate Lower section is fixed with upper mould fixed plate, and upper mould fixed plate lower section is provided with backing plate, and backing plate is connected by some Rectangular Springs with upper die plate, And the tensile elongation of the Rectangular Spring is more than the thickness of upper mould fixed plate；Fixed plate, fixed plate lower section are fixed with below backing plate Holding pad is connected with by some Rectangular Springs；The centre position below upper die plate, is further fixed on piercing punch, the piercing punch Upper mould fixed plate, backing plate, fixed plate and holding pad are passed down through, when upper mould is not acted on by external force, the drift position of piercing punch Inside holding pad, when upper mould is acted on by external force, when Rectangular Spring is compressed, the drift part of piercing punch will extend pressure Flitch lower section, is punched out；In the lower section of backing plate, the outside of piercing punch, molding concave-convex mold is provided with, inside the molding concave-convex mold For hollow structure, external diameter of its hollow space internal diameter more than or equal to piercing punch；The molding concave-convex mold be passed down through fixed plate and Holding pad；When fixed plate and holding pad are not acted on by external force, the lower end of molding concave-convex mold is located inside holding pad, works as fixed plate When being upwarded pressure by downward pressure or holding pad, molding concave-convex mold stretches out from holding pad bottom, to product to be processed Product carry out Shape correction.

Lower mould includes lower template, die, molding concave die and perforating die；Wherein, die is fixed on the top of lower template, wherein Heart position is provided with molding concave die, and the location and shape of the molding concave die are corresponding with the molding concave-convex mold in upper mould, in molding concave die Perforating die is provided with inside middle hollow space, the position of the perforating die is corresponding with the piercing punch in upper mould with shape, and And the top edge of perforating die, less than the top edge of molding concave die, both differences in height are flange width.

Advantage of the present utility model and beneficial effect are：The forming and punching mould structure is simple and convenient to operate, once into Type, instead of traditional multi-step process, can greatly improve production efficiency, reduction in the numbers of seconds, improve product quality；Together When can save the turnover of manpower, the device space and multiple working procedure, reduce production cost.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Hereinafter implement Example is only used for clearly illustrating the technical solution of the utility model, and protection model of the present utility model can not be limited with this Enclose.

The technical scheme that this utility model is embodied as is：

As Figure 1-3, it is the structure chart of finished product, punching moulding section therein needs to carry out flange after punching again whole Shape.

As shown in figure 4, for the overall front view of forming and punching mould, being made up of upper mould 1 and lower mould 2；Wherein, upper mould 1 Top is upper die plate 11, and in the lower section of upper die plate 11 upper mould fixed plate 12 is fixed with, and the lower section of upper mould fixed plate 12 is provided with backing plate 14, Backing plate 14 is connected by two Rectangular Springs 13 with upper die plate 11；Fixed plate 15 is fixed with below backing plate 14, under fixed plate 15 Side is connected with holding pad 17 by two Rectangular Springs 13；The centre position below upper die plate 11, is further fixed on piercing punch 18, The piercing punch 18 is passed down through upper mould fixed plate 12, backing plate 14, fixed plate 15 and holding pad 17；In the lower section of backing plate 14, punching The outside of hole punch 18, is provided with molding concave-convex mold 16；As Figure 7-8, the inside of molding concave-convex mold 16 is hollow structure, wherein External diameter of the empty part internal diameter more than or equal to the stem portion of piercing punch 18；The molding concave-convex mold 16 is passed down through fixed plate 15 and pressure Flitch 17.

Lower mould 2 includes lower template 21, die 22, molding concave die 23 and perforating die 24；Wherein, die 22 is fixed on lower template 21 top, its center is provided with molding concave die 23, and the location and shape of the molding concave die 23 are concavo-convex with the molding in upper mould 1 The correspondence of mould 16, inside the hollow space in the middle of molding concave die 23 perforating die 24 is provided with, the position of the perforating die 24 and shape with Piercing punch 18 in upper mould 1 is corresponding, and the top edge of perforating die 24 is less than the top edge of molding concave die 23.

During normal work, processed product is placed on lower mould 2, upper mould 1 is pressed downward, due to one group of rectangle on top Spring 13 bear a heavy burden it is less than one group of Rectangular Spring 13 of bottom, therefore, one group of Rectangular Spring 13 on the top of upper mould 1 is subject to upper pressure First compressed afterwards, make the drift on piercing punch 18 extend out to the lower section of holding pad 17, be punched out；Press through in the case where upper mould 1 continues Cheng Zhong, one group of Rectangular Spring 13 of the bottom of upper mould 1 is compressed so that the lower section of holding pad 17 is stretched out in the lower end of molding concave-convex mold 16, Flange process is carried out towards processed products.

Wherein, the external surface shape of molding concave-convex mold 16 can be customized according to product demand, molding concave die 23 and punching The top edge difference in height of mould 24 is adjusted also dependent on flange width, it is not limited to the shape in the present embodiment and accompanying drawing And difference in height.

The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of without departing from this utility model know-why, some improvements and modifications can also be made, these change Enter and retouch also to should be regarded as protection domain of the present utility model.
