Abstract

The utility model relates to a die, in particular to a twitching side-punching die used for hole side-punching. The twitching side-punching die comprises an upper die base, a lower die base and a material pressing plate. A sliding chute composed of a wear-resisting plate and a press plate which are on the upper die base is used for driving a sliding block to move horizontally so as to drive a punch installed in a slant mode to perform slant movement, and hole side-punching operation is carried out. Under the condition that a punch-blanking step is not added, the twitching side-punching die is convenient to maintain, simple and stable in structure, low in manufacturing cost, and capable of achieving side-punching of dense multiple holes.

Description

Twitch formula side blow mould

Technical field

The utility model relates to a kind of mould, is specially the twitch formula side blow mould of using in the side blow hole.

Background technology

General side blow mould, when the hole bit comparison was intensive, mould had independent guiding mechanism, driving mechanism and resetting-mechanism, mould structure is relatively large, and must add a stamping-out work step could show, thereby has increased the cost of mould, has prolonged the manufacturing cycle of mould.

The utility model content

In order to solve the problems of the technologies described above, it is a kind of simple in structure that the utility model provides, the mould that cost is low, require high to finish the position, hole, the punching press product of position compactness, concrete technical scheme is: twitch formula side blow mould, comprise upper bolster, die shoe and holding pad, the upper bolster below is fixedly connected with backing plate, the fixedly connected slide block backing plate in backing plate below, the slide block backing plate has slide block in the middle of the below, both sides are equipped with wearing plate and pressing plate, slide block horizontal direction in the chute of wearing plate and pressing plate composition is slided, the slide block upper surface is the inclined-plane, and the drift backing plate is fixedly connected on the slide block upper surface, and the hole on the slide block is passed at the drift top, be fixedly connected on the drift backing plate, drift is oblique; Holding pad is fixedly connected on binder backboard below, and lower portion of ram is passed the hole in binder backboard and the holding pad; Lower bolster is installed die shoe and counterdie is gone into son.

In the binder backboard fairlead is arranged, fairlead is fixed on the binder backboard with briquetting, and drift passes fairlead.

The mould that the utility model provides, the chute that utilizes wearing plate on the upper bolster and pressing plate to form drives the slide block horizontal movement, thus the drift that drives oblique installation is done oblique movement, carries out the operation of side blow hole.

The utility model provides a kind of easy to maintenance under the situation that does not increase the stamping-out work step, simple and stable structure, and the mould structure that production cost is low can be realized intensive porous side blow.

Tool is stopped embodiment

The accompanying drawings specific embodiment of the present utility model, as shown in Figure 1, Figure 2, Figure 3 and Figure 4,

Twitch formula side blow mould, comprise upper bolster 14, die shoe 6 and holding pad 17, upper bolster 14 belows are fixedly connected with backing plate 1, the fixedly connected slide block backing plate 7 in backing plate 1 below, there are slide block 3, both sides that wearing plate 11 and pressing plate 12 are installed in the middle of slide block backing plate 7 belows, slide block 3 horizontal direction in the chute of wearing plate 11 and pressing plate 12 compositions is slided, slide block 3 upper surfaces are the inclined-plane, drift backing plate 2 is fixedly connected on slide block 3 upper surfaces, the hole on the slide block 3 is passed at drift 4,9 tops, be fixedly connected on the drift backing plate 2, drift 4,9 is oblique; Holding pad 17 is fixedly connected on binder backboard 16 belows, and the hole in binder backboard 16 and the holding pad 17 is passed in drift 4,9 bottoms; Lower bolster 10 is installed die shoe 6 and counterdie is gone into son 5.

Fairlead 8 is arranged in binder backboard 16, and fairlead 8 usefulness briquettings 13 are fixed on the binder backboard 16, and drift 4,9 passes fairlead 8.

Upper bolster 14, backing plate 1, slide block backing plate 7, wearing plate 11, pressing plate 12 are formed drive block, on the inclined-plane of active force and slide block 3, drive slide block 3 and slide when working downwards by punch press.

Slide block 3 has protruding spigot surface and pressing plate 12 wearing plates 11 to slide mutually, by pressing plate 12 and wearing plate 11 guiding, has guaranteed the accuracy of slide block 3 moving tracks in slide block 3 sliding processes, guarantees the accuracy of punching; Pressing plate 12, wearing plate 11 be split type, be convenient to processing, change.

The course of work is:

The mould closing course is placed on counterdie to blanking part and goes on the son 5, and punch press begins downward work, and holding pad 17 compresses blanking part earlier; Punch press continues to move downward, and upper bolster 14 is delivered to the power of punch press on the slide block 3 by backing plate 1, slide block backing plate 7, wearing plate 11, drives slide block 3 and slides; Simultaneously, slide block 3 drives drift 4,9 and does oblique motion down, and this is tiltedly down to being the punching direction; Die shoe 14 continues descending arrival punch press bottom dead centre, and stamping-out work is finished;

The mould opening procedure, punch press is upwards taken exercises, and promotes upper bolster 14, and slide block 3 resets thereupon, and the drive drift 4,9 that resets of slide block 3 moves obliquely along fairlead 8, goes into son 5 up to disengaging lower bolster 10, counterdie; Punch press continues up holding pad 17 and breaks away from blanking parts, and blanking part is broken away from die shoe goes on the son 5, and punch press is up to top dead-centre, and whole stamping-out work is finished.

Claims

1. twitch formula side blow mould, comprise upper bolster, die shoe and holding pad, it is characterized in that: the upper bolster below is fixedly connected with backing plate, the fixedly connected slide block backing plate in backing plate below, and the slide block backing plate has slide block, both sides that wearing plate and pressing plate are installed in the middle of the below, slide block horizontal direction in the chute of wearing plate and pressing plate composition is slided, the slide block upper surface is the inclined-plane, and the drift backing plate is fixedly connected on the slide block upper surface, and the hole on the slide block is passed at the drift top, be fixedly connected on the drift backing plate, drift is oblique; Holding pad is fixedly connected on binder backboard below, and lower portion of ram is passed the hole in binder backboard and the holding pad; Lower bolster is installed die shoe and counterdie is gone into son.

2. twitch formula side blow mould according to claim 1 is characterized in that in the described binder backboard fairlead being arranged, and fairlead is fixed on the binder backboard with briquetting, and drift passes fairlead.
