Description

Stroke compensation type stamping sliding block mechanism

Technical Field

The utility model relates to a field of punch press mould, concretely relates to stroke compensation type punching press slider mechanism.

Background

When a traditional punching die is used for designing a sliding block, a fixed inclined wedge is generally designed on an upper die, a working sliding block is designed on a lower die, when a punching machine descends, the working sliding block slides under the action of the inclined wedge, the stroke of the working sliding block is equal to the stroke of the upper die after the upper die is inclined to contact with the working sliding block and then descends, if the required stroke of the working sliding block is large, the stroke requirement of the punching machine is large, a special punching machine is needed, the development cost of products is improved, the stroke is large, the punching times per minute of the punching machine are reduced, and the capacity can be greatly reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a stroke compensation type punching press slider mechanism, solve because the punch press stroke is limited and influence the problem of work slider stroke, have simple structure, low cost's advantage.

The purpose of the utility model is accomplished through following technical scheme: the stroke compensation type stamping slider mechanism comprises a lower die lower slider base and a working slider, wherein a fixed wedge is fixedly arranged on the lower die lower slider base, a working slider stop block is arranged on one side, away from the fixed wedge, of the lower die lower slider base, and the working slider stop block is connected with the working slider through a working slider reset spring so that the working slider is abutted against the fixed wedge and slides left and right along the lower die lower slider base; one side that the work slider is close to fixed slide wedge is equipped with the inclined plane, forms the contained angle between the slide wedge face of this inclined plane and fixed slide wedge, is fixed with the top shoe through last slider base directly over this contained angle, and the last slider base left and right sides all is equipped with the top shoe dog on last mould that is connected with the punch press, and the top shoe passes through top shoe reset spring to be connected with the top shoe dog of one side to along last slider base horizontal slip, this top shoe head is the triangle-inverted and is used for the cooperation the contained angle.

As a preferable technical scheme, the vertex angle of the upper sliding block is the same as the included angle, and both the vertex angle and the included angle are 90 degrees.

As a further technical scheme, when an upper die of the punch press is closed downwards, the sliding stroke of the working slide block along the lower die lower slide block base is equal to the width of the head of the upper slide block.

The utility model has the advantages that: under the condition that the downward stroke of the die is fixed, the stroke of the working slide block can be adjusted by adjusting the width size of the upper slide block, so that the larger stroke sliding of the working slide block is realized on the basis of the smaller downward stroke of the die, and the downward stroke of the die is compensated, so that the requirement on the stroke of a punching machine can be reduced; the utility model discloses simple structure is applicable to all and carves formula slider to one side, can reduce the mould stroke of opening and shutting of die, and then improves the production productivity greatly.

Description of reference numerals: lower die lower slide block base 1, fixed wedge 2, upper slide block 3, upper die upper slide block base 4, upper slide block dog 5, upper slide block reset spring 6, work slide block 7, work slide block reset spring 8, work slide block dog 9.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in fig. 1, the stroke compensation type stamping slider mechanism comprises a lower die lower slider base 1 and a working slider 7, wherein a fixed wedge 2 is fixedly arranged on the lower die lower slider base 1, a working slider stop block 9 is arranged on one side, away from the fixed wedge 2, of the lower die lower slider base 1, and the working slider stop block 9 is connected with the working slider 7 through a working slider return spring 8, so that the working slider 7 is abutted against the fixed wedge 2 and slides left and right along the lower die lower slider base 1; one side that work slider 7 is close to fixed slide wedge 2 is equipped with the inclined plane, forms the contained angle between this inclined plane and the slide wedge face of fixed slide wedge 2, is fixed with last slider 3 through last slider base 4 directly over this contained angle, and the last slider base 4 left and right sides of last mould that is connected with the punch press goes up the mould all is equipped with slider dog 5, and last slider 3 is connected with the last slider dog 5 of one side through last slider reset spring 6 to along last slider base 4 horizontal slip of mould, 3 heads on this last slider are the inverted triangle-shaped and are used for the cooperation the contained angle. As shown in fig. 2, the top angle B of the upper slider 3 is the same as the included angle, preferably 90 °. As shown in fig. 3, when the upper die of the punch press is closed downward, the stroke of the slide of the work slide 7 along the lower die lower slide base 1 is equal to the width a of the head of the upper slide 3.

The utility model discloses a working process: at the beginning, the mechanism is in a mold opening state, and the upper slide block 3 is positioned right above an included angle formed by the inclined plane of the working slide block 7 and the inclined wedge surface of the fixed inclined wedge 2 (as shown in figure 1); when an upper die of a punch press is closed downwards, an upper sliding block 3 moves downwards to contact a fixed inclined wedge 2 (shown in figure 2), the upper sliding block 3 moves rightwards along an upper die upper sliding block base 4 under the action of an inclined wedge surface, meanwhile, the right side of the upper sliding block 3 is in contact with a working sliding block 7, the working sliding block 7 is pushed to slide rightwards along a lower die lower sliding block base 1 until the left side and the right side of the upper sliding block 3 are attached to the fixed inclined wedge 2 and the working sliding block 7 respectively (shown in figure 3), the stroke of the working sliding block 7 is equal to the width A of the upper sliding block 3 at the moment, the stroke of the working sliding block 7 can be adjusted by adjusting the width A of the upper sliding block 3 under the condition that the descending stroke of the punch press is certain, so that the large-stroke sliding of the working sliding block 7 is realized on.
