Description

Technical Field

[0001] This utility model relates to upsetting, specifically to an upsetting structure. Background Technology

[0002] In the field of metal plastic forming, upsetting is a core forming method widely used in industrial scenarios such as rebar connection and shaft parts manufacturing. The structural design of the upsetting die directly affects processing efficiency, product accuracy, and ease of operation. Currently, mainstream upsetting equipment on the market (such as rebar upsetting machines and shaft upsetting devices) generally uses traditional bolt fastening or welding methods to connect the pressure head to the base plate. However, this type of structure has gradually revealed many limitations in practical applications. Utility Model Content

[0003] In view of the above problems, this utility model proposes an upsetting structure.

[0004] The technical solution of this utility model: An upsetting structure includes an upper pressure head and a lower pressure head. The upper pressure head is mounted on an upper base plate, and the lower pressure head is mounted on a lower base plate, with the upper and lower pressure heads facing each other. An upper connector is fixed on the upper base plate, and the lower end of the upper connector is connected to the upper pressure head via a T-shaped structure and secured with screws. The T-shaped structure consists of a T-groove and a T-head.

[0005] To further refine the above technical solution, washers are provided at both ends of the T-shaped groove, and there are two screws in total. The two screws pass through the washers and are connected to the T-shaped head; the washers are stuck on the step at the end of the T-shaped groove.

[0006] To further refine the above technical solution, the lower pressure head is supported on the lower base plate and connected to the lower base plate via a guide pin; the guide pin is centered, with its upper end inserted into a pin groove at the bottom of the upper pressure head and its lower end inserted into a pin hole on the lower base plate.

[0007] To further refine the above technical solution, a shim is placed at the bottom of the pressing head, and the shim is fitted onto the guide pin.

[0008] The advantages of this utility model are that it has a reasonable design, simple structure, and is extremely convenient to install, adjust, and disassemble. Attached Figure Description

[0009] Figure 1 This is a schematic diagram (partial cross-section) of the upsetting structure installation.

[0010] The diagram shows: 1. Upper pressure head; 2. Lower pressure head; 3. Upper base plate; 4. Lower base plate; 5. Upper connection; 6. T-shaped structure; 7. Screw; 8. Washer; 9. Guide pin; 10. Elevating block. Detailed Implementation

[0011] As shown in the figure, an upsetting structure is provided, which includes an upper pressure head 1 and a lower pressure head 2. The upper pressure head 1 is mounted on an upper base plate 3, and the lower pressure head 2 is mounted on a lower base plate 4. The upper pressure head 1 and the lower pressure head 2 are opposite to each other. An upper connection 5 is fixed on the upper base plate 3. The lower end of the upper connection 5 is connected to the upper pressure head 1 through a T-shaped structure 6 and fixed with two screws 7. The T-shaped structure 6 consists of a T-shaped groove and a T-shaped head. Washers 8 are provided at both ends of the T-shaped groove. The two screws 7 pass through the washers 8 and are connected to the T-shaped head. The washers 8 are stuck on the step at the end of the T-shaped groove. The lower pressure head 2 is supported on the lower base plate 4 and connected to the lower base plate 4 through the guide pin 9; the guide pin 9 is centered, with its upper end inserted into the pin groove set at the bottom of the upper pressure head 2 and its lower end inserted into the pin hole set on the lower base plate 4; a shim block 10 is placed at the bottom of the lower pressure head 2 and is fitted on the guide pin 9.

[0012] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
