Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for powder metallurgy processing. Background Technology

[0002] Powder metallurgy is an industrial technology that produces metal materials, composite materials, and various types of products by taking metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, and then forming and sintering them. Powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weaponry, biology, new energy, information, and nuclear industries, becoming one of the most dynamic branches of new materials science. Some materials and complex parts that cannot be prepared by traditional casting and machining methods can also be manufactured using powder metallurgy technology, thus attracting much attention from the industry. Currently, in the processing and production of powder metallurgy, most of the clamping devices are manually clamped using pliers, which often results in the workpiece falling to the ground. Furthermore, existing powder metallurgy clamping devices are prone to causing wear and scratches on the workpiece surface, making them inconvenient to use and impractical.

[0003] Therefore, after searching the existing technology, it was found that the currently disclosed patent technology, such as the clamping device for powder metallurgy processing proposed in publication number CN219485733U, has the following beneficial effects: 1. When using the clamping device for powder metallurgy processing, the operation of the rotating motor will cause the bevel gear two to rotate, thereby causing the meshing bevel gear one to drive the threaded rod to rotate. Through the reverse threads at both ends of the threaded rod, the two threaded blocks will move in opposite directions on the surface of the threaded rod, which facilitates the clamping and adjustment of powder metallurgy workpieces and the clamping of workpieces of different sizes, thus overcoming the inconvenience of existing manual clamping; 2. When using the clamping device for powder metallurgy processing, when the rotating motor drives the two mounting blocks to move closer to each other, the mounting plate and protective pad on one side of the mounting block contact the surface of the workpiece. The protective pad is subjected to the squeezing force, which causes the spring to contract to one side. The protective pad increases the protection of the workpiece surface and avoids wear and scratches on the surface.

[0004] However, in actual use, existing clamping devices for powder metallurgy processing and production are limited because the workpieces to be clamped vary in shape. The clamping device described in this paper can only clamp flat workpieces. When it is necessary to clamp irregularly shaped workpieces, the corresponding clamping plate needs to be replaced. The replacement of existing clamping plates is time-consuming and laborious, thus reducing the efficiency and effectiveness of the clamping device and resulting in poor practicality.

When clamping irregularly shaped workpieces, the corresponding clamping plates must be replaced, which is time-consuming and labor-intensive. Therefore, this invention enhances the efficiency and effectiveness of the clamping device, thus improving its practicality for powder metallurgy processing.
