Description

Bending machine die

Technical Field

The invention relates to the technical field of bending machine dies, in particular to a bending machine die.

Background

And a bending machine die, wherein English is pressbraketool. The bending machine is used for forming and processing the plate, the tool is composed of various parts, and different dies are composed of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. And a tool for forming the blank into a product with a specific shape and size under the pressure of the bending machine. Generally, T8 or T10 and T10A are used, and some 42CrMo materials are preferable, the requirements of the 42CrMo materials are mainly high strength, high toughness and good wear resistance, cold work die steel is selected, Cr12MoV is a good material, the service performance can be met, the process performance is good, the price is high, 42CrMo is alloy quenched and tempered steel with high strength, the strength is high, the toughness is good, and the 42CrMo material can work below 500 ℃. From the development process of the die of the numerical control bending machine, the die material of the numerical control bending machine mainly represents high-speed steel from the end of the nineteenth century to the middle of the twentieth century; in 1927, Germany firstly developed the die material of the hard alloy numerical control bending machine and obtained wide application; in the 50 s of the twentieth century, synthetic diamonds were synthesized separately in sweden and in the united states, and from then on, cutting of dies for numerical control bending machines was stepped into the period represented by superhard materials. In the 70 s of the twentieth century, people synthesized polycrystalline diamond (PCD) by using a high-pressure synthesis technology, so that the problems of rare quantity and high price of natural diamond are solved, and the application range of the diamond numerical control bending machine die is expanded to a plurality of fields such as aviation, aerospace, automobiles, electronics, stone and the like.

The roller in the roller type U forming section die of the traditional bending machine is relatively serious in abrasion due to bearing the compression force from the bending piece and the upper die, the roller of the traditional bending machine die is mostly fixedly installed in the lower die through a bolt, the roller is long-term corroded or deformed by the bolt, the roller is difficult to disassemble and install, the use of the bending machine is influenced, and therefore a combined bending machine die is designed to solve the problems.

Disclosure of Invention

The purpose of the invention is: the bending machine die overcomes the defects in the prior art, and is long in service life, convenient in part replacement and high in machining precision.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

the utility model provides a bending die, includes terrace die and die, the die is fixed on the mount, the die below is provided with two back shafts of buckling to the work piece with the terrace die cooperation, the die below is provided with the first spigot surface and the second spigot surface of buckling to the work piece with the terrace die cooperation, and two back shafts are located the both sides of first spigot surface and second spigot surface respectively, the concave surface below is provided with elastomeric element respectively in horizontal direction and vertical direction.

Further, the elastic component is a compression spring.

Furthermore, a lifting rod is arranged inside the compression spring in the vertical direction.

Furthermore, the lifting rod comprises a fixed rod and a lifting rod, a movable cavity is arranged in the fixed rod, the outer diameter of the lifting rod is smaller than the inner diameter of the movable cavity, and the lifting rod is driven by a hydraulic cylinder.

Furthermore, the lifter comprises a fixed rod and a lifter, a movable cavity is arranged in the fixed rod, the outer diameter of the lifter is smaller than the inner diameter of the movable cavity, and the lifter is driven by a pneumatic cylinder.
