Description

Technical Field

[0001] The utility model relates to an upsetting device and belongs to the technical field of workpiece upsetting. Background Art

[0002] Upsetting is a common forming method in the plastic forming process. In the process of round steel processing, it is usually necessary to perform upsetting on one or both ends to meet the special requirements of the product.

[0003] The Chinese utility model patent with the authorization announcement number CN218744629U proposes "a round steel upsetting device that can be clamped and positioned", including a bottom plate and two detachable limit plates. A positioning plate is welded and fixed at the left end of the bottom plate. The limit plates are arranged at the upper and lower ends of the positioning plate in relative directions and buckled together to clamp and fix the round steel. First, the steel pipe is placed in the semicircular positioning cavity on the lower limit plate, and then the second hydraulic cylinder drives the upper limit plate to descend, and the limit plates are tightly buckled together to complete the positioning operation of the workpiece. After positioning, the hydraulic cylinder drives the upsetting table to move to one side of the workpiece, and the upsetting of the workpiece is completed by the pressure given by the upsetting table. When it is necessary to perform upsetting operations on different workpieces, the fixing bolts can be loosened, and the limit plates can be moved according to the size of the workpiece. After adjustment, the fixing bolts can be tightened. At the same time, when it is necessary to adjust the length of the upsetting, the front and rear positions of the upsetting table can be adjusted in advance, and then the upsetting operation can be performed, which can improve the overall upsetting effect.

[0004] However, after research, it is found that in the above patent, when both ends of the round steel workpiece need to be upset, only one end of the round steel workpiece can be upset first, and then the machine is stopped to change the direction of the round steel workpiece before the other end can be upset, which is inconvenient and time-consuming. Therefore, the utility model proposes an upsetting device to solve the above problem. Utility Model Content

At the right end of the top of the bottom plate 1, a second mounting plate 5 is fixedly connected. At the center of the right end face of the second mounting plate 5, a second hydraulic cylinder 7 is fixedly connected through a plurality of second bolts 6. The output end of the first hydraulic cylinder 4 penetrates through the right end face of the first mounting plate 2 and is telescopically matched with the first mounting plate 2. A first upsetting head 8 is mounted on the output end of the first hydraulic cylinder 4 penetrating through the right end face of the first mounting plate 2. The output end of the second hydraulic cylinder 7 penetrates through the left end face of the second mounting plate 5 and is telescopically matched with the second mounting plate 5. A second upsetting head 9 is mounted on a part of the output end of the second hydraulic cylinder 7 penetrating through the left end face of the second mounting plate 5. Both the first upsetting head 8 and the second upsetting head 9 are columnar heads, and the first upsetting head 8 and the second upsetting head 9 are coaxially arranged.

[0024] In the above technical solution, by fixedly connecting the first hydraulic cylinder 4 to the first mounting plate 2 with the first bolts 3 and fixedly connecting the second hydraulic cylinder 7 to the second mounting plate 5 with the second bolts 6, and respectively mounting the first upsetting head 8 and the second upsetting head 9 on the output ends of the first hydraulic cylinder 4 and the second hydraulic cylinder 7, the present utility model can not only upset one end of the round steel, but also upset both ends of the round steel simultaneously, which is more convenient and fast when both ends of the round steel need to be upset.

[0025] In the present utility model, a vertical plate 10 is fixedly connected at the central position between the first mounting plate 2 and the second mounting plate 5 at the top of the bottom plate 1. A groove 11 is formed at the top of the vertical plate 10. A workpiece opening 12 penetrating the vertical plate 10 is formed on the left side surface of the vertical plate 10, and the workpiece opening 12 penetrates the groove 11. A group of clamping blocks 13 are placed in the groove 11. Arc-shaped grooves 14 are formed on the adjacent surfaces of a group of the clamping blocks 13. When the adjacent surfaces of a group of the clamping blocks 13 are abutted against each other, the arc-shaped grooves 14 formed on the adjacent surfaces of a group of the clamping blocks 13 form a workpiece hole. Cylinders 15 are mounted on both the front end face and the rear end face of the vertical plate 10. The output end of the cylinder 15 penetrates through the surface of the vertical plate 10 and extends into the groove 11. A pushing block 16 is threadedly connected to the output end of the cylinder 15. The pushing block 16 is a circular pushing block 16, and the end of the pushing block 16 away from the cylinder 15 abuts against the surface of the clamping block 13.

[0026] In the above technical solution, a set of grooves 11 are formed at the top of the vertical plate 10, and a set of clamping blocks 13 are placed in the grooves 11, so that when the utility model clamps and fixes round steel with different diameters, it is more convenient to replace the clamping blocks 13 with annular grooves of different sizes. By setting the cylinder 15, the output end of the cylinder 15 extends out and can push a kind of clamping block 13 to slide towards each other in the groove 11 through the pushing block 16 to clamp and fix the round steel workpiece, so as to facilitate the upsetting process of the round steel workpiece.

[0027] In the utility model, in order to enhance the connection between the vertical plate 10 and the first mounting plate 2 and the second mounting plate 5, connecting rods 17 are provided at the positions between the vertical plate 10 and the first mounting plate 2 and the second mounting plate 5, and the connecting rods 17 are located directly above the workpiece opening 12.

[0028] During use, first select a set of clamping blocks 13 with different calibers according to the diameter of the round steel workpiece to be upset and place them in the grooves 11, then place the round steel workpiece in the arc-shaped grooves 14 on the clamping blocks 13. The cylinders 15 are synchronously started to drive the pushing blocks 16 to move towards each other, and then a set of clamping blocks 13 can be pushed closer to clamp the round steel workpiece in the workpiece hole. When it is necessary to upset one end of the round steel workpiece, turn on the first hydraulic cylinder 4 or the second hydraulic cylinder 7 at the corresponding end to be upset, and the round steel workpiece can be upset at one end; when it is necessary to upset both ends of the round steel workpiece, turn on the first hydraulic cylinder 4 and the second hydraulic cylinder 7 at the same time, and the round steel workpiece can be upset at both ends. The operation is convenient and more time-saving.

[0029] In this article, specific examples are used to elaborate on the principle and implementation mode of the utility model.
