Description

Technical Field

[0001] The utility model relates to the technical field of hexagonal steel processing, and particularly relates to a cold drawing and diameter reducing mechanism for hexagonal steel. Background Technique

[0002] Hexagonal steel is a type of section steel, also known as a hexagonal bar, which is a bar with a regular hexagonal cross-section. The nominal size is the length of the opposite sides S. Hexagonal steel can be used to form various load-bearing components according to different structural requirements, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves. During the processing of hexagonal steel, a cold drawing and diameter reducing mechanism is required to perform cold drawing and diameter reducing processing on the hexagonal steel. The cold drawing and diameter reducing die is the core component of the cold drawing and diameter reducing processing. In order to perform cold drawing and diameter reducing processing on hexagonal steel of different models, it is necessary to frequently replace the cold drawing and diameter reducing die. However, after the cold drawing and diameter reducing die is installed, it is generally not easy to quickly remove it, and tools are required to remove the cold drawing and diameter reducing die for replacement, which is time-consuming and affects the processing of hexagonal steel. Therefore, a cold drawing and diameter reducing mechanism for hexagonal steel is proposed to facilitate the disassembly and replacement of the cold drawing and diameter reducing die. Content of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a cold drawing and diameter reducing mechanism for hexagonal steel.

[0004] The technical solution adopted by the utility model to solve its technical problems is a cold drawing and diameter reducing mechanism for hexagonal steel, which includes a processing table. A clamping member is provided at the top of the processing table. A cold drawing and diameter reducing die, a support, a baffle, and a clamping block are provided on one side of the clamping member. The baffle is welded to the top of the processing table. A first hydraulic cylinder is fixed on the side of the baffle away from the cold drawing and diameter reducing die. The piston rod of the first hydraulic cylinder penetrates through the baffle and is connected to the support by bolts. A clamping groove adapted to the cold drawing and diameter reducing die is provided on the side of the support away from the baffle. The bottom end of the clamping block penetrates through the support and the cold drawing and diameter reducing die. Two stoppers are fixed on the top of the support. The clamping block is located between the two stoppers. Two grooves are provided on the side of the clamping block away from the clamping member. Plug blocks are provided in both grooves. Slots adapted to the ends of the plug blocks are provided on the opposite side walls of the two stoppers. Two guide posts are fixed on the opposite side walls of the two plug blocks. Springs are sleeved on each guide post. Four sliding grooves for the guide posts to slide are provided on the clamping block. Push blocks are fixed on the side walls of the two plug blocks.

[0005] By adopting the above technical solution, the two pushing blocks are pushed to move towards each other, and the two inserting blocks move towards each other. The ends of the two inserting blocks are disengaged from the two stoppers. The upper shifting block can be used to remove the block. Hold the cold drawing and reducing die and pull it to remove and replace it. During installation, place the end of the cold drawing and reducing die in the card slot on one side of the support. Push the two pushing blocks. After inserting the bottom end of the block into the support and the cold drawing and reducing die, release the two pushing blocks. The spring pushes the inserting block to reset, and the ends of the two inserting blocks are inserted into the two stoppers, which can prevent the block from displacing and facilitate the installation of the cold drawing and reducing die.

[0006] Specifically, anti-slip pads are fixed on the opposite side walls of the two pushing blocks.

[0007] By adopting the above technical solution, the setting of the anti-slip pads is beneficial to pushing the pushing blocks.

[0008] Specifically, a handle is fixed at the top end of the block.

[0009] By adopting the above technical solution, holding the handle makes it convenient to pick up and place the block.

[0010] Specifically, the clamping member includes a bracket and a second hydraulic cylinder. The bracket is welded to the top end of the processing table. Second hydraulic cylinders are fixed on both sides of the bracket. Hexagonal steel clamping blocks are fixed on the piston rods of the two second hydraulic cylinders.

[0011] By adopting the above technical solution, the piston rods of the two second hydraulic cylinders drive the two hexagonal steel clamping blocks to move towards the hexagonal steel placed on the processing table. The two hexagonal steel clamping blocks are close to the hexagonal steel, which is convenient for clamping the hexagonal steel.

[0012] Specifically, two guide rods are fixed on the opposite side walls of the two hexagonal steel clamping blocks. All four guide rods penetrate through the bracket.

[0013] By adopting the above technical solution, the setting of the guide rods can improve the stability of the hexagonal steel clamping blocks.

[0014] Specifically, two cross bars are fixed on the side of the support away from the cold drawing and reducing die. The ends of the two cross bars away from the support penetrate through the baffle.

[0015] By adopting the above technical solution, the setting of the cross bars can improve the stability of the support.

During installation, place the end of the cold drawing and diameter reduction die in the card slot on one side of the support. Push the two push blocks, insert the bottom end of the clamping block into the support and the cold drawing and diameter reduction die, and then release the two push blocks. The spring pushes the insertion block back to its original position, and the ends of the two insertion blocks are inserted into the two stop blocks, which can prevent the displacement of the clamping block and facilitate the installation of the cold drawing and diameter reduction die.
