Detailed Description

In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.

Referring to fig. 1 and 2, the punch press for quick-changing a steel backing mold of a brake pad of the present utility model includes a punch press body 1 and a clamp 2; the punch body 1 is provided with a workbench 11 and a sliding block 12 vertically moving towards the workbench 11, and a plurality of sliding grooves 3 are formed in the surface of the workbench 11 and one end surface of the sliding block 12 towards the workbench 11;

the clamp 2 comprises a pressing end and a sliding seat 21 matched with the sliding groove 3, wherein the pressing end is used for pressing the edge of the die.

From the above description, the beneficial effects of the utility model are as follows: the clamp 2 which is arranged on the chute 3 in a sliding way is additionally arranged on the workbench 11 and the sliding block 12 of the punch body 1, so that the clamp 2 can be far away from the die along the chute 3 when the die is disassembled. When the die is fixed, the pressing end of the clamp 2 can be pressed at the edge of the die, so that the die is prevented from shaking in the operation process of the punch body.

Referring to fig. 2, further, the fixture 2 further includes an oil cylinder 22 and a pressing block 23, the oil cylinder 22 is disposed on the sliding seat 21, and one end of the pressing block 23 is hinged with a movable end of the oil cylinder 22;

when the movable end of the oil cylinder 22 extends out, one end of the pressing block 23, which is far away from the oil cylinder 22, is abutted against the edge of the die; when the movable end of the cylinder 22 is retracted, the end of the pressing block 23 away from the cylinder 22 is away from the edge of the die.

As is apparent from the above description, when the mold needs to be clamped, the movable end of the cylinder 22 is extended, and the pressing block 23 can be abutted against the edge of the mold, thereby fixing the mold. When the die needs to be replaced, the movable end of the oil cylinder 22 is retracted, so that the pressing block 23 can be loosened, and the die is quickly replaced.

Further, the sliding groove 3 is a T-shaped groove, the large groove wide end of the T-shaped groove on the working table 11 is far away from the table top of the working table 11, and the large groove wide end of the T-shaped groove on the sliding block 12 is far away from the sliding block 12 and faces to one end face of the working table 11.

As is apparent from the above description, the chute 3 of the T-shaped groove not only facilitates the movement of the clip 2 but also can prevent the clip 2 from jumping in the vertical direction.

Referring to fig. 1 and 3, further, a placement plate 13 is disposed on the punch body 1, and the placement plate 13 and the punch body 1 enclose a storage space for storing the clamp 2.

As is clear from the above description, when the jig 2 is temporarily detached from the table 11 or the slider 12, the jig 2 can be temporarily placed on the punch body 1 through the storage space surrounded by the placement plate 13 and the punch body 1, so that the line for detaching the jig 2 is eliminated.

As shown in fig. 3, further, the placement plate 13 is provided with a relief opening 131, the relief opening 131 communicates with the accommodating space, and the accommodating space only allows the sliding seat 21 to extend in.

As is apparent from the above description, only the slide 21 of the jig 2 is extended into the receiving space, so that the rest of the jig 2 is exposed to the outside, thereby facilitating the operator to take the jig 2.

The utility model relates to an application scene of a punch press for quickly replacing a steel back die of a brake block, which comprises the following steps: when the die on the punch body 1 needs to be replaced, the clamp 2 which is arranged on the chute 3 in a sliding manner is additionally arranged on the workbench 11 and the sliding block 12 of the punch body 1, so that the clamp 2 can be far away from the die along the chute 3 when the die is disassembled.
