Description

Technical Field

[0001] The invention relates to the technical field of bolt forging, in particular to an anti-dumping hot pressing forming device for processing automobile bolts. Background Art

[0002] In the machinery manufacturing industry, bolts are widely used as connectors, and their quality directly affects the overall performance and safety of the equipment. With the acceleration of industrialization, the demand for bolts has increased dramatically, and at the same time, higher requirements have been placed on the processing accuracy, efficiency and cost control of bolts. As an advanced plastic processing method, hot pressing technology has shown unique advantages in the field of metal forming. Its basic principle is to heat the material to a certain temperature to soften it and have good plasticity, and then use molds and pressure equipment to process the material into the desired shape. Compared with cold processing, hot pressing technology has the advantages of high processing accuracy, high material utilization rate, and low processing stress. It is especially suitable for processing parts with high dimensional accuracy requirements.

[0003] The existing hot pressing equipment has a low degree of specialization, which makes it difficult to quickly produce bolts of different sizes and shapes by changing molds. If the bolt is placed offset, it will not be correctly positioned in the center, which will affect the product quality. In addition, due to the lack of precise cooling of the bolt parts, the bolt parts are prone to deformation during shrinkage due to lack of temperature control during the hot pressing process, which seriously affects the quality of bolt production and the production efficiency of the bolts. Summary of the invention

[0005] A support assembly, the support assembly is fixedly installed at the top middle of the base;

[0006] The pressure component is fixedly installed at the middle of the bottom of the slider, and the pressure component and the support component are located on the same vertical plane;

[0007] The supporting assembly includes a shell, which is fixedly mounted at the middle of the top of the base, a through hole is opened in the middle of the shell, and a fixing piece is arranged on the inner wall of the through hole;

[0008] Preferably, the fixing member includes a cylinder, which is slidably connected to the shell, and the bottom of the cylinder is fixedly connected with a compression spring, and one end of the compression spring away from the cylinder is fixedly connected to the top of the base, and an inner cavity is opened inside the cylinder. The staff places the blank to be processed inside the shell so that the bottom of the blank is located inside the fixing member, and utilizes the elastic performance of the spring plate to make the middle part of the trapezoidal block closely contact with the outer side of the material, so as to fix and clamp the blank to prevent the blank from translating or rotating during the hot pressing process. Sufficient clamping force is evenly provided to the blank through multiple trapezoidal blocks, so that the blank is located in the correct center position to ensure that the blank does not move during the hot pressing process. At the same time, different clamping forces are provided according to different diameters of the blank. The narrow side of the trapezoidal block facilitates the initial positioning of the blank, and the bottom width is wider for dispersing the clamping force to avoid local damage to the blank. A square hole is opened on the inner wall of the cylinder, and a trapezoidal block is fixedly connected to the inner wall of the square hole. The trapezoidal block is elastic, and a spring plate is fixedly connected to the inner wall of the trapezoidal block.

[0009] Preferably, a groove is provided at the top of the shell, a mold is provided on the inner wall of the groove, a block is fixedly connected to the inner wall of the through hole, and the hydraulic cylinder works, and the hydraulic cylinder drives the slider to slide downward on the guide rod, so that the pressure head at the bottom of the slider extrude the heated blank, so that the blank can be completely formed under the pressure, and the cylinder exerts pressure on the compression spring, and the compression spring is compressed. At this time, the cylinder slides inside the through hole through the block, and the guiding cooperation between the block and the slide groove can avoid deviation and shaking during the movement, thereby preventing damage to the mold and the workpiece, and at the same time avoiding the bolts from being stuck in the mold, affecting the work efficiency, and frequent jamming may damage the mold and increase the production cost. There are multiple blocks, and the multiple blocks are evenly distributed with the fixing part as the center, the groove is T-shaped, and a threaded groove is provided on the inner wall of the groove close to the fixing part, and an oblique groove is provided at the top edge of the shell.

The side edge of the trapezoidal block extends to the inside of the inner cavity through the square hole, and the inner wall of the inner cavity is fixedly connected with an elastic plate. When a blank with a small diameter is clamped, the trapezoidal block moves in a direction away from the elastic plate under the elastic force of the elastic plate. At this time, the end of the side edge of the trapezoidal block moves in the square hole away from the middle of the trapezoidal block under the action of its own elastic force. Since the trapezoidal block is provided with an arc groove on the side close to the blank, the middle part of the trapezoidal block shrinks and deforms, thereby reducing the contact area between the trapezoidal block and the blank, thereby reducing the clamping force on the blank and avoiding plastic deformation of the blank due to excessive extrusion. If the blank is subjected to excessive clamping force in the clamp, Deformation or displacement, after being placed in the mold, it is impossible to ensure correct cooperation with the mold cavity, resulting in deviation of the formed bolts.

The round rod passes through the cylinder and extends to the inside of the inner cavity. The end of the spring plate away from the trapezoidal block is fixedly connected to the inner wall of the cylinder, and an arc groove is provided on the side of the trapezoidal block away from the round rod.

When the mold needs to be replaced for production of products of different specifications or mold maintenance, the operation is simple and fast, and no complicated cutting and disassembly tools are required, saving time and labor costs. The installation position of the mold can be fine-tuned to a certain extent by the degree of screwing in or out to meet the requirements for mold assembly accuracy. After the mold is installed, the staff places the blank to be processed inside the support assembly, the lower end of the blank is located inside the fixing part, and the upper end of the blank is located inside the mold.
