Abstract

The utility model provides a mould which is simple in structure, improves machining precision and avoids a rebounding phenomenon of a bent part. The mould comprises a punch, an upper mould and a lower mould, wherein the punch clamps a stamping part, and the upper mould and the lower mould are matched with the punch. The upper mould comprises an upper mould plate, an upper cushion plate and a fixed plate, wherein the upper cushion plate is fixed on the upper mould plate, the fixed plate is installed below the upper cushion plate, and a swaying punch is installed below the fixed plate. The lower mould comprises a lower mould plate, a concave mould cushion plate and a concave mould plate, wherein the concave mould cushion plate is fixed on the lower mould plate, a tapered wedge and an insert are placed in the concave mould plate, the top surface of the insert and the lateral side of the insert are tightly attached to a machining bending portion of the stamping part, an included angle in a range of 3-5 degrees is inwards and concavely formed between the lateral side of the machining bending portion and the vertical direction, and one side, close to the insert, of the wedge is provided with a slope. The mould for improving rebounding of the bent part is simple in structure, and capable of improving machining precision, and avoiding the rebounding phenomenon of the bent part.

Description

Improve the mould of bending component resilience

Technical field

The utility model relates to a kind of fine blanking die, refers more particularly to the mould that can improve the bending component resilience.

Background technology

Diel is that material is carried out the equipment that pressure processing is used, and its operation principle generally is to drive the folding of patrix and counterdie and setting such as raw material between with it cut, punching, stretching under the effect of punching press by mould, the formation stamping parts.According to the operation principle of forcing press, can be divided into mechanical press and hydraulic press.Mechanical press is to finish punching course by the Motor Drive slide block movement, and hydraulic press is by hydraulic principle, drives the reciprocating motion of hydraulic pressure steel and finishes punching course.Mechanical press work reciprocating frequence is fast, speed height, efficient height, but the power that produces is less, generally is used for mini-type punching equipment, and punching, shearing technology.The force rate that the hydraulic pressure function produces is bigger, but speed is slower, and is general for stretching, moulding production, also is used for punching press and the shearing of heavy parts.

Fine blanking die is that present existing product is made the novel mould in field.It is combined by the punch-die that cooperates up and down usually, and punch-die is fixed by upper padding plate, and upper padding plate and cope match-plate pattern are fixed.When the part to the needs bending carried out punching press, because part itself has screen resilience, the bending part of stamping parts can produce the resilience of trace when punch lifted after the punching press, had influenced smart quality and working (machining) efficiency of dashing.

Summary of the invention

Technical problem to be solved in the utility model is the technical deficiency at above-mentioned existence, provides a kind of simple in structure, improves the precision of processing, prevents the mould of bending component rebound phenomenon.

The technical scheme that its technical problem that solves the utility model adopts is:

Improve the mould of bending component resilience, include the drift that clamps stamping parts and the upper and lower mould that cooperates with drift, patrix comprises cope match-plate pattern, upper padding plate and fixed head, upper padding plate is fixedly arranged on the cope match-plate pattern, install fixed head under the upper padding plate, install under the fixed head and wave drift, counterdie comprises lower bolster, die backing plate and concave template, the die backing plate is fixedly arranged on the lower bolster, install concave template on the die backing plate, it is characterized in that: wedge is arranged in concave template and insert, insert end face and side are adjacent to the processing kink of stamping parts, and its side be provided with vertical direction in be recessed into 3 °-5 ° angle, wedge has the inclined-plane near the side of inserting.

In such scheme, the described drift that waves also is provided with the inclined-plane over against the one side of wedge.

The beneficial effects of the utility model are: simple in structure, can improve the precision of processing, and prevent the bending component rebound phenomenon.

Description of drawings

Fig. 1 is the utility model embodiment overall structure figure;

Among the figure: 1, cope match-plate pattern, 2, upper padding plate, 3, fixed head, 4, lower bolster, 5, the die backing plate, 6, concave template, 7, wave drift, 8, wedge, 9, insert, 10, stamping parts.

The specific embodiment

Below in conjunction with the specific embodiment, the utility model is further described:

The mould that improves the bending component resilience as shown in Figure 1, include the drift that clamps stamping parts and the upper and lower mould that cooperates with drift, patrix comprises cope match-plate pattern 1, upper padding plate 2 and fixed head 3, upper padding plate 2 is fixedly arranged on the cope match-plate pattern 1, upper padding plate is installed fixed head 32 times, what fixed head had been installed the bending effect for 3 times waves drift 7, counterdie comprises lower bolster 4, die backing plate 5 and concave template 6, die backing plate 5 is fixedly arranged on the lower bolster 4, install concave template 6 on the die backing plate 5, wherein wedge 8 is arranged and insert 96 li of concave templates, insert end face and side 9 are adjacent to the processing kink of stamping parts 10, inserting 9 is adjacent in the side of stamping parts and the vertical direction and is recessed into 5 ° of angles, and wedge 8 has the inclined-plane near 9 the side of inserting.

In the present embodiment, the described drift 7 that waves also is provided with the inclined-plane over against the one side of wedge 8.

The utility model embodiment utilizes wedge 8 and 9 actings in conjunction of inserting, clamp and wave drift 7 when impacting, and make the part bending part bends 5 ° more, the influence of the screen resilience of counteracting own, the utility model apparatus structure is simple, can improve the precision of processing, prevent the bending component rebound phenomenon.

Claims (2)

1. improve the mould of bending component resilience, include the drift that clamps stamping parts and the upper and lower mould that cooperates with drift, patrix comprises cope match-plate pattern, upper padding plate and fixed head, upper padding plate is fixedly arranged on the cope match-plate pattern, install fixed head under the upper padding plate, install under the fixed head and wave drift, counterdie comprises lower bolster, die backing plate and concave template, the die backing plate is fixedly arranged on the lower bolster, install concave template on the die backing plate, it is characterized in that: wedge is arranged in concave template and insert, insert end face and side are adjacent to the processing kink of stamping parts, and its side be provided with vertical direction in be recessed into 3 °-5 ° angle, wedge has the inclined-plane near the side of inserting.
2. the mould that improves the bending component resilience as claimed in claim 1, it is characterized in that: the described drift that waves also is provided with the inclined-plane over against the one side of wedge.
