Description

Technical Field

[0001] The invention relates to the technical field of hexagonal steel processing, and in particular to a cold drawing reduction structure with an easily replaceable mold. Background Art

[0002] Hexagonal steel is a kind of steel, also known as hexagonal bar, with a regular hexagonal cross section. The length of opposite sides S is the nominal size. Hexagonal steel can be composed of various load-bearing components according to different structural needs, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves. In the process of hexagonal steel processing, a cold drawing and shrinking mechanism is required to perform cold drawing and shrinking on the hexagonal steel. The cold drawing and shrinking die is the core component of the cold drawing and shrinking process. In order to perform cold drawing and shrinking on different types of hexagonal steel, the cold drawing and shrinking die needs to be replaced frequently. However, the cold drawing and shrinking die is generally not easy to be removed quickly after installation. It is necessary to use tools to remove and replace the cold drawing and shrinking die, which is time-consuming and affects the processing of hexagonal steel. Therefore, a cold drawing and shrinking structure with easy mold replacement is proposed to facilitate the disassembly and replacement of the cold drawing and shrinking die. Summary of the invention

The bottom end of the clamping block passes through the support and the cold drawing shrinking die, and two blocks are fixed on the top of the support. The clamping block is located between the two blocks. Two grooves are provided on the side of the clamping member away from the clamping member, and plug blocks are provided in the two grooves. The facing side walls of the two blocks are provided with slots that match the ends of the plug blocks. Two guide columns are fixed on the facing side walls of the two plug blocks, and each guide column is provided with a spring. Four sliding grooves for the guide columns to slide are provided on the clamping block, and push blocks are fixed on the side walls of the two plug blocks.

[0005] By adopting the above technical solution, the two push blocks are pushed to move toward each other, the two plug blocks are moved toward each other, the ends of the two plug blocks are disengaged from the two stop blocks, the card block can be removed by moving the card block upward, and the cold drawing shrinking mold can be removed and replaced by holding it and pulling it. During installation, the end of the cold drawing shrinking mold is placed in the card slot on one side of the support, the two push blocks are pushed, the bottom end of the card block is inserted into the support and the cold drawing shrinking mold, and then the two push blocks are released. The spring pushes the plug block to reset, and the ends of the two plug blocks are inserted into the two stop blocks, which can prevent the card block from being displaced and facilitate the installation of the cold drawing shrinking mold.

[0006] Specifically, anti-slip pads are fixed to the side walls of the two push blocks facing away from each other.

[0007] By adopting the above technical solution, the provision of the anti-slip pad is conducive to pushing the push block.

[0012] Specifically, two guide rods are fixed to the opposite side walls of the two hexagonal steel clamping blocks, and the four guide rods all penetrate the bracket.

[0013] By adopting the above technical solution and setting the guide rod, the stability of the hexagonal steel clamping block can be improved.

[0014] Specifically, two cross bars are fixed to a side of the support away from the cold drawing and shrinking die, and ends of the two cross bars away from the support both penetrate the baffle.

[0026] When in use, push the two push blocks 18 to move toward each other, and the two plug blocks 13 to move toward each other, and the ends of the two plug blocks 13 will disengage from the two stop blocks 12.
