Abstract

The utility model discloses an oscillating type punching die which comprises an upper die plate, an oscillating punch head, an oscillating spring, a lower die plate, a female die and a driving block. The upper end of the oscillating punch head is hinged to the upper die plate, and the oscillating spring abuts against the oscillating punch head and the upper die plate. The female die and the driving block are both fixed on the lower die plate, the driving block is placed on one side of the female die, and the distance between the female die and the driving block is matched with the width of the lower end of the oscillating punch head so that the oscillating punch head can penetrate. The oscillating punch head which can oscillate around the hinged point is used in the oscillating type punching die, through matching of the oscillating punch head and the driving block, the two processes of side cutting and front cutting can be completed in one-side punching process, the lapping defect of products caused by repeated positioning and multiple times of processing is overcome, and the quality of the produced products is high.

Description

The swing type blanking die

Technical field

The utility model relates to a kind of blanking die mould, particularly relates to the swing type blanking die that a kind of IMD diaphragm is die-cut and aluminum alloy casing is die-cut.

Background technology

As shown in Figure 1 C, the side of product has breach, very common moulding in the shells such as electronic appliance, automobile, traditional production method is: by product 10(to be processed as shown in Figure 1A) be placed on counterdie, cut (as shown in Figure 1B) and twice die-cut completing of one tangent (as shown in Figure 1 C) by one side.Both wasting manpower and material resources's while product produced step (lapping defect) and error because resetting reaches repeatedly processing, had influence on the quality of product when serious.

The utility model content

The purpose of this utility model is to provide a kind of high swing type blanking die of product quality of production.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of swing type blanking die, and it comprises cope match-plate pattern, swings drift, swing spring, lower bolster, die, drive block; The upper end of described swing drift is hinged on cope match-plate pattern, and swing spring leans and swinging between drift and cope match-plate pattern; Described die and drive block all are fixed on lower bolster, and drive block is positioned at a side of die, and the distance between die and drive block matches with the width that swings the drift lower end, in order to allow the swing drift penetrate.

Described swing drift and drive block opposite face are all arc surface.

After adopting such scheme, because the utility model adopts the swing drift that can swing around its pin joint, by with the coordinating of drive block, just can complete side in a side blow pressure process cuts and the tangent two procedures, avoided product because of resetting and repeatedly processed the defect that produces lapping defect, the product quality of production is high.

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

The accompanying drawing explanation

Figure 1A is product figure to be processed;

Product figure after Figure 1B commonly uses side in processing and cuts;

Fig. 1 C commonly uses the product figure after tangent in processing;

Fig. 2 is front view of the present utility model;

Fig. 3 is that the utility model starts die-cut schematic diagram;

Fig. 4 is the die-cut schematic diagram of the utility model side;

Fig. 5 is the positive die-cut schematic diagram of the utility model.

The specific embodiment

As shown in Figure 2, the utility model is a kind of swing type blanking die, and it comprises cope match-plate pattern 1, swings drift 2, swing spring 3, lower bolster 4, die 5, drive block 6, rotating shaft 7.

The upper end of described swing drift 2 is hinged on cope match-plate pattern 1 by rotating shaft 7, and swing spring 3 leans and swinging between drift 2 and cope match-plate pattern 1.

Described die 5 and drive block 6 all are fixed on lower bolster 4, and drive block 6 is positioned at a side of die 6, and the distance between die 5 and drive block 6 matches with the width that swings drift 2 lower ends, in order to allow swing drift 2 penetrate.The interval imported between die 5 and drive block 6 in order to swing drift 2, swing drift 2 and be all arc surface with drive block 6 opposite faces 21,61.

Operation principle of the present utility model:

As shown in Figure 2, the utility model is designed to swing convertible swing drift 2 by traditional straight line rule drift, by rotating shaft 7 and swing spring 3, drives and will swing drift 2 rotations to suitable position.As shown in Figure 3, when the drive block 6 on lower bolster 4 is prepared to start working, the drift edge of a knife does not produce and interferes product; When cope match-plate pattern 1 continues to descending, drive block drives swing drift 2 that product side 10 is cut to (as shown in Figure 1B), and the front that swings 2 pairs of products of drift when the product side cuts does not produce interference, and as shown in Figure 4, swing drift 2 and ajusted this time; As shown in Figure 5, continue to descending swing drift 2 product 10 positive die-cut complete (as shown in Figure 1 C) when cope match-plate pattern 1.After die sinking, swing drift 2 and set back under the driving of swing spring 3.

Emphasis of the present utility model just is: drift is designed to swing convertible swing drift.

The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims
