Description

Technical Field

[0001] The utility model belongs to the technical field of forging clips, and in particular relates to a high-temperature resistant forging clip. Background Art

[0002] Clamps are essential clamping tools in forging production, primarily used to clamp or release products and coordinate with robotic arms to transfer products between workstations. Forging operations typically occur in high-temperature environments, where the clamp's jaws come into direct contact with the hot product and must bear a significant weight. Metal easily deforms in high-temperature environments, and existing forging clamps have limited load-bearing capacity. When forging heavy parts, the connecting components are prone to malfunction, resulting in a short lifespan for the clamps.

[0003] A Chinese utility model with authorization publication number CN219357806U discloses a high-temperature-resistant forging clamp, comprising a turntable, a pull rod, and two clamping jaws. The turntable is transmission-connected to a first drive unit, the pull rod is transmission-connected to a second drive unit mounted on the turntable, and two connecting rods are hinged to the pull rod. Each connecting rod is hinged to a clamping jaw, and the two clamping jaws are hinged. By sequentially hingedly connecting the clamping jaws, the connecting rod, and the connecting rod, the pull rod achieves a transmission connection from the pull rod to the two clamping jaws. This extends the length of the entire transmission mechanism, facilitating the location of the drive unit away from high temperatures, reducing the impact of high temperatures on the drive and transmission mechanisms, and extending their service life. By locating the hinged portion of the two clamping jaws in the middle, the lever arm is shortened. Under the same torque output, the two clamping jaws have a stronger clamping force and can more stably clamp the product. The provision of a first cavity and a second cavity strengthens the heat insulation and splash protection of the drive unit and transmission mechanism, respectively, further extending the service life of the clamp. However, the clamp has poor load-bearing capacity in high-temperature environments, and the various connecting components are prone to malfunction. Utility Model Content

[0017] Example 1:

[0018] like Figure 1-Figure 3As shown, the utility model provides a high-temperature resistant forging clamp, including a load-bearing base plate 1, the load-bearing base plate 1 is extended with a clamping portion 2, the load-bearing base plate 1 is fixedly installed with a support 3, a guide seat 4 and a cylinder 5, the support 3 is movably installed with a splint 7 through a shaft 6, the two ends of the splint 7 are respectively provided with a chuck 8 and a connecting rod 9, the guide seat 4 is provided with an arc groove 10, the cylinder 5 is driven and connected with a driving member 11, the driving member 11 is provided with an inclined groove 12, and the connecting rod 9 is sequentially inserted into the inclined groove 12 and the arc groove 10. A pressure plate 13 is fixedly installed on the top of the guide seat 4. A splashproof shell 14 is fixedly installed on the load-bearing base plate 1. The load-bearing base plate 1 is carbon alloy structural steel. The load-bearing base plate 1 is fixedly installed with the cylinder 5 through the heat insulation member 15.

[0019] Through the above technical scheme, the utility model takes the load-bearing base plate 1 as the supporting basis, and a clamping part 2 is extended on the load-bearing base plate 1. The load-bearing base plate 1 is fixedly installed with a support 3, a guide seat 4 and a cylinder 5. The support 3 is movably installed with a splint 7 through an axis rod 6. A chuck 8 and a connecting rod 9 are respectively provided at both ends of the splint 7. When clamping the forged workpiece, the cylinder 5 pushes the driving part 11 to move, and the inclined groove 12 of the driving part 11 cooperates with the arc groove 10 of the guide seat 4, forcing the connecting rod 9 to lift, so that the chuck 8 of the splint 7 is close to the clamping part 2 of the load-bearing base plate 1, completing the clamping process of the forged workpiece. The weight of the clamped forged workpiece is transferred to the load-bearing base plate 1 through the clamping part 2. The load-bearing base plate 1 and the clamping part 2 are an integrated structure, which improves the load-bearing energy of the utility model, prevents the loosening of the connecting components, and improves the service life of the forging clamp.

[0020] Example 2:

[0021] like Figure 1-Figure 3As shown, the present invention includes a load-bearing base plate 1, which is the load-bearing structure of the present invention. The extended portion of the load-bearing base plate 1 is provided with a clamping portion 2, the main function of which is to clamp the forged workpiece. A plurality of supports 3, a guide seat 4, and a cylinder 5 are fixedly mounted on the structure of the load-bearing base plate 1. The support 3 is movably mounted with a clamping plate 7 via a shaft 6, so that the clamping plate 7 can move with the shaft 6 as a fulcrum. A chuck 8 and a connecting rod 9 are provided at both ends of the clamping plate 7, respectively. The chuck 8 of the clamping plate 7 cooperates with the clamping portion 2 of the load-bearing base plate 1 to form the ability to clamp the forged workpiece. An arcuate groove 10 is provided inside the guide seat 4, which is used to guide the trajectory of the connecting rod 9 during movement. The cylinder 5 is an important driving device of the entire clamping system. It drives the driving member 11 connected thereto through changes in air pressure. The driving member 11 is provided with an inclined groove 12, and the connecting rod 9 is inserted into the inclined groove 12 and the arcuate groove 10 in sequence. This arrangement enables the action of the cylinder 5 to be effectively transmitted to the connecting rod 9 during the process of clamping the forged workpiece, thereby driving the movement of the clamping plate 7. When the utility model clamps the forged workpiece, the cylinder 5 will extend outward, pushing the driving member 11 forward. In this process, the inclined groove 12 cooperates with the arc groove 10 to force the connecting rod 9 to move. One end of the connecting rod 9 is lifted, thereby pushing one end of the clamping plate 7 (the end with the connecting rod 9) to move upward. At the same time, the chuck 8 at the other end of the clamping plate 7 will also approach the clamping part 2 of the load-bearing base plate 1, ultimately achieving effective clamping of the forged workpiece. The load-bearing base plate 1 plays a vital supporting role in this clamping process, bearing the weight of the clamped forged workpiece and ensuring the stability and durability of the clamping device under high temperature conditions. Under high temperature conditions, metal materials often deform after forging, affecting the clamping ability of the clamp. The load-bearing capacity of a clamp is often an important indicator to measure its performance. The load-bearing capacity of existing forging clamps is weak under high temperature conditions, which can easily cause abnormalities in various connected components, which directly affects the service life of the clamp. Therefore, the present invention has optimized the material selection and structural design to enhance the durability of the clamp under high temperature conditions. The material of the load-bearing base plate 1 is a high-temperature resistant alloy material to ensure that it does not soften or deform at high temperatures. The connection between the support 3, the guide seat 4 and the cylinder 5 adopts a high-strength fixing method to prevent loosening or damage during the clamping process. The surface of the chuck 8 has been specially treated to enhance the friction between it and the forged part and prevent slippage during the clamping process. The cylinder 5 serves as a driving device, and its working principle plays a core role in the entire clamping process. In actual work, the cylinder 5 can achieve precise clamping force adjustment through the control of air pressure. The operator can adjust the air pressure of the cylinder 5 according to the weight and material properties of the forged workpiece to control the clamping force.

[0022] A pressure plate 13 is fixedly installed on the top of the guide seat 4 of the present invention. The main function of the guide seat 4 is to provide a stable sliding guide structure for the driver 11 so that the driver 11 can move smoothly during operation. The pressure plate 13 can effectively prevent the driver 11 from falling off during movement, ensuring that the driver 11 can slide freely within the specified track, while also preventing clamping failures caused by position offset. During operation, when the cylinder 5 extends and pushes the driver 11 to move, the sliding of the driver 11 within the guide seat 4 can be guided by the pressure plate 13. The restraining effect of the pressure plate 13 on the driver 11 enables it to maintain linear motion during movement, preventing lateral deviation caused by external force or its own gravity. This structural design improves the stability and safety of the entire clamping device and ensures the accuracy and consistency of the clamping process. The fixing method of the pressure plate 13 and the guide seat 4 can be bolted, welded or other mechanical fixing methods to ensure that it will not loosen under high load and high temperature environments. Through a reasonable fixing method, the pressure plate 13 and the guide seat 4 form a solid combination, so that the driving member 11 always maintains a stable position during the sliding process, avoiding accidental falling off due to vibration or impact.

[0023] A splash shield 14 is fixedly mounted on the load-bearing base plate 1 of the present invention. The main function of the splash shield 14 is to prevent high-temperature sputtering generated during the forging process from damaging the internal structure. Such sputtering is usually composed of tiny particles generated by metal during the heating and forging process, which has a high temperature and kinetic energy. If it is not protected, it will have a negative impact on the service life of the fixture. During the forging process, the metal is heated to an extremely high temperature and external force is applied, causing its surface material to splash outward. The presence of the splash shield 14 can effectively block these sputterings and prevent them from entering the interior of the fixture, thereby protecting the integrity of the internal structure. The splash shield 14 is tightly combined with the load-bearing base plate 1 to form an effective protective barrier. This barrier is not only a physical protection, but also blocks the conduction of thermal radiation to a certain extent, reducing the impact of high temperature on the load-bearing base plate 1 and its accessories. In a high temperature environment, the load-bearing base plate 1 needs to withstand the gravity of the forging workpiece while also resisting the influence of the external temperature. Therefore, the additional protection provided by the splash shield 14 is particularly important. Furthermore, the splash shield 14 is constructed with a multilayer composite material to further enhance its high-temperature resistance and structural strength. This multilayer composite material not only provides improved thermal insulation but also effectively disperses the impact of high-temperature splashes, reducing the direct impact on the load-bearing substrate 1. This structural design ensures effective protection without adding excessive weight, thus maintaining the fixture's flexibility and operability.

[0024] The material of the load-bearing base plate 1 of the present invention is carbon alloy structural steel. Carbon alloy structural steel has good mechanical properties and high temperature resistance. During the forging process, the load-bearing base plate 1 bears the gravity of the entire clamp, and also needs to withstand the heat load in a high temperature environment. Therefore, the use of carbon alloy structural steel as the material can effectively prevent the load-bearing base plate 1 from deforming in a high temperature environment. Another reason why carbon alloy structural steel is used in the design of the load-bearing base plate 1 is its good deformation resistance. At high temperatures, the structure of metal materials may be affected by thermal stress, causing plastic deformation of the material. Carbon alloy structural steel has a low creep rate at high temperatures, which means that even under high temperature conditions, its degree of deformation is relatively small, thereby ensuring that the geometric shape and clamping performance of the load-bearing base plate 1 are not affected. This feature is crucial for the long-term stable operation of the forging clamp.

[0025] The load-bearing base plate 1 of the present invention is fixedly mounted with the cylinder 5 via a heat insulating member 15. The provision of the heat insulating member 15 is intended to effectively prevent the heat generated by the load-bearing base plate 1 during operation from damaging the cylinder 5. During the forging process, metal materials are processed under high temperature conditions, and the temperature of the load-bearing base plate 1 will increase due to direct contact with high-temperature objects. If this temperature increase is directly transmitted to the cylinder 5, it will have a negative impact on the material and internal working mechanism of the cylinder 5, reduce its working efficiency, and even cause the cylinder 5 to fail. As a key actuator in the forging clamp, the cylinder 5 is responsible for driving the movement of the clamp 7, and its internal structure and working principle are very sensitive to temperature changes. In a high-temperature environment, the lubricating oil inside the cylinder 5 may degrade due to excessive temperature, resulting in lubrication failure, thereby causing increased wear and malfunction of the cylinder 5. Therefore, the provision of the heat insulating member 15 can not only protect the structural integrity of the cylinder 5, but also extend its service life, ensuring the stability and reliability of the clamp at high temperatures. The material of the thermal insulation 15 is ceramic fiber, high temperature resistant plastic or special alloy, etc., which can effectively reduce the transfer of heat, so that the cylinder 5 is kept in a relatively low temperature range during operation, thereby ensuring the normal operation of the cylinder 5. The design of the thermal insulation 15 requires not only that it has good thermal insulation performance, but also that it has sufficient strength to withstand the mechanical shock and vibration generated by the cylinder 5 during operation. The fixing method of the thermal insulation 15 can be bolt connection, welding or other forms of mechanical fixation to ensure that the thermal insulation 15 can remain stable under the high-intensity impact during the forging process. During the installation process, it is necessary to ensure that the connection between the thermal insulation 15 and the load-bearing base plate 1 is firm to avoid loosening of the thermal insulation 15 due to temperature changes or mechanical vibrations, which affects the thermal insulation effect. In the surface treatment of the thermal insulation 15, considering the corrosiveness and wear in high temperature environments, a wear-resistant coating or a corrosion-resistant coating can be used to improve its durability. At the same time, a sealing material can be set between the thermal insulation 15 and the cylinder 5 to further reduce the transfer of heat. The selection of the sealing material needs to take into account the high temperature resistance to ensure that aging or failure does not occur during operation. The shape and structure of the thermal insulator 15 also need to be optimized based on the specific installation location and the operating principle of the cylinder 5. The thermal insulator 15 can be tailored to the shape of the cylinder 5, ensuring a close fit and forming a more effective insulation layer. This optimally designed shape not only provides excellent insulation but also reduces installation space, improving the overall compactness of the device.
