Description

Punch fixing structure and quick-change punch assembly

Technical Field

The invention relates to the technical field of stamping dies, in particular to a punch fixing structure and a quick-change punch assembly.

Background

In the punching process, the use of the punch is very extensive. How to rapidly replace the punch in the batch processing process and improve the stamping efficiency is one of the research subjects of the design and manufacture of the stamping die at present.

In the prior art, the quick-change punch is fastened mostly in a ball locking manner, but the ball locking punch and a fixing seat thereof have complicated structures and large manufacturing difficulty, so that the cost of the die is high.

Disclosure of Invention

In order to solve the problems, the invention provides a punch fixing structure with an exquisite design and a quick-change punch assembly with low cost and simple and convenient operation.

The invention protects a punch fixing structure, which comprises a locking plate horizontally arranged in a fixed seat and an unlocking block vertically arranged in the fixed seat, wherein the locking plate is used for embedding and locking a punch, and the unlocking block is used for quickly disassembling the punch; the unlocking block is provided with a notch which faces away from the punch and is provided with a first slope surface inclining downwards; the thickness of the locking plate is slightly smaller than the height of the opening, a vertical through groove for the unlocking block to pass through is formed in the locking plate, and a second slope surface matched with the first slope surface is arranged on the inner wall of the through groove.

Furthermore, one side, far away from the punch, of the locking plate is provided with a compression spring, and a plug is arranged outside the compression spring.

The invention also discloses a quick-change punch assembly which comprises a fixed seat and a punch arranged on the fixed seat, wherein the punch is fixed through the punch fixing structure.

Furthermore, the fixing seat is vertically provided with a punch mounting hole and an unlocking block mounting hole, and is horizontally provided with a locking plate mounting hole and a compression spring mounting hole, wherein the locking plate mounting hole and the compression spring mounting hole are in a vertical relation on the same horizontal plane.

Furthermore, the top of the punch mounting hole is provided with a step, a T-shaped base plate is embedded into the step, and the punch is fixedly connected with the T-shaped base plate.

The quick-locking and quick-changing structure is ingenious in structural design and simple and convenient to operate, can realize quick installation and replacement of the punch or other parts, and reduces the cost of a stamping die compared with a traditional ball locking and quick-changing structure.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific examples. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

Example 1

The utility model provides a drift fixed knot constructs, as shown in fig. 1, fig. 2, including the level set up locking plate 2 in the fixing base, vertically set up unblock piece 7 in the fixing base, locking plate 2 is used for embedding and locking drift 4, unblock piece 7 is used for dismantling drift 4 fast.

A notch 8 facing away from the punch is arranged on the unlocking block 7, and the notch 8 is provided with a first slope surface 9 inclining downwards as shown in fig. 3; the thickness of the locking plate is slightly smaller than the height of the opening, a vertical through groove 10 for the unlocking block to pass through is arranged on the locking plate, and a second slope 11 matched with the first slope 9 is arranged on the inner wall of the through groove 10, as shown in fig. 4 and 5.

For the fixing mode of the locking plate, the following scheme is adopted for implementation: and a compression spring 6 is arranged on one side, away from the punch, of the locking plate 2, and a plug 5 is arranged outside the compression spring 6.

Example 2

A quick-change punch assembly comprises a fixing seat 1 and a punch 4 installed on the fixing seat, wherein the punch 4 is fixed through the punch fixing structure.

The fixing seat is vertically provided with a punch mounting hole 12 and an unlocking block mounting hole 13, and is horizontally provided with a locking plate mounting hole 14 and a compression spring mounting hole 15, wherein the locking plate mounting hole 14 and the compression spring mounting hole 15 are in a vertical relation on the same horizontal plane, as shown in fig. 6.

The first installation process: inserting a punch; inserting a locking plate; inserting an unlocking block; fourthly, inserting a compression spring and locking by a plug screw so that the locking plate is embedded into the punch under the action of the compression spring.

The disassembling process comprises the following steps: unscrewing a plug; secondly, the unlocking block is pulled out upwards, the first slope surface moves upwards, and the locking block is driven to move laterally until the punch head is separated from the locking state; and thirdly, disassembling the pump head.
