Description

Steel pipe punching die guiding device

Technical Field

The utility model relates to the technical field of machining, concretely relates to die-cut mould guider of steel pipe.

Background

In the existing tower crane parts, a plurality of steel pipe parts are provided, and the parts are generally punched and blanked. The cutter plate is stressed greatly in the punching process, so that the die is easy to deform, the clearance of the cutter plate is increased, and the like, thereby causing unqualified parts. Because of the variety of parts, the angle of the punching die needs to be adjusted sometimes, but the adjusting process is complicated, and if the angle is not adjusted to the position, the interference of the cutting board is easy to cause danger.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a die-cut mould guider of steel pipe to the cutting board that exists among the solution prior art warp easily and goes up the cutting board and is difficult to the problem of adjusting well with lower cutting board.

In order to achieve the purpose, the guide device for the steel pipe punching die comprises an upper die, a lower die, an upper cutting board and a lower cutting board, wherein the upper cutting board is fixedly arranged on the upper die, and the lower cutting board is fixedly arranged on the lower die; the upper knife board is provided with a guide block, the lower die is provided with a guide groove, and the guide groove is used for the guide groove to pass in and out.

Further, the concentration of the guide grooves is equal to the height of the guide block.

Furthermore, the number of the guide blocks is two, the guide blocks are arranged on two sides of the upper knife board, and the number of the guide grooves is two.

Further, still include the contact piece, the contact piece is fixed to be set up in the guide way.

Further, the contact block is made of wear-resistant materials.

The utility model has the advantages that: through setting up the guide block on last cutting board, set up the guide way on the lower mould, can make last cutting board and lower cutting board operate the accuracy when carrying out die-cut, when die-cut steel pipe that has certain angle, can guarantee to go up mould and lower mould and rotate simultaneously to make last cutting board and lower cutting board can accurately adjust well.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1, a steel pipe punching die guiding device comprises an upper die 1, a lower die 2, an upper cutting board 3 and a lower cutting board 4, wherein the upper cutting board 3 is fixedly arranged on the upper die 1, and the lower cutting board 4 is fixedly arranged on the lower die 2; the upper knife board 3 is provided with a guide block 31, the lower die 2 is provided with a guide groove 21, and the guide groove 21 is used for the guide block 31 to go in and out. When punching a steel pipe, the steel pipe is placed on the lower die 2. The structure has two functions by arranging the guide block 31 and the guide groove 21, firstly, when the steel pipe is punched, the upper knife board 3 and the lower knife board 4 can be accurately operated, namely, when the plane of the upper knife board 3 meets the plane of the lower knife board 4 (like scissors), the planes are positioned on the same tangent plane, so that the punching quality is better; secondly, some steel pipes need to be formed into a certain angle during punching (namely, the steel pipes are not punched perpendicular to the steel pipes, but are inclined by an angle), so that the upper die 1 and the lower die 2 are adjusted to rotate at the same time, but in reality, the actions are difficult to cooperate and accord, and the upper knife plate 3 and the lower knife plate 4 are staggered. Through setting up guide block 31 and guide way 21, when needs go up mould 1 and lower mould 2 and rotate, choose to go up cutting board 3 and descend, make guide block 31 stretch into in the guide way 21, then rotatory mould 1 and lower mould 2, just so can ensure that last cutting board 3 and lower knife 4 board can be aligned accurately.

Specifically, the depth of the guide groove 21 is equal to the height of the guide block 31, so that the cutting edge of the upper blade 3 can be brought into contact with the upper surface of the lower die 2 at the time of die cutting the pipe steel, without causing the upper blade 3 to be further pushed down toward the lower die 2, which may cause damage to the upper blade 3.

Specifically, two guide blocks 31 are provided on both sides of the upper blade 3, and two guide grooves 21 are provided.

In addition, the device also comprises a contact block 22, and the contact block 22 is fixedly arranged in the guide groove 21. This is to accurately limit the downward movement of the guide block 31, so as to ensure that the plate surface of the upper knife plate 3 and the plate surface of the lower knife plate 4 are on the same tangent plane. Since the mold needs to be operated frequently, the material of the contact block 22 is set to be a wear-resistant material such as high manganese steel.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes that can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art can be made within the scope of the claims of the present invention.
