Description

Technical Field

[0001] This utility model relates to the field of hot pressing devices, specifically to a hot pressing clamping fixture. Background Technology

[0002] Hot pressing involves heating an item that needs to be compacted or compressed, then using hydraulic pressure or heavy-load extrusion to compress it. Hot pressing technology is designed based on the technical requirements of high temperature and high pressure, and is mainly used in powder densification, solid-phase component diffusion welding, and composite material preparation. Hot pressing achieves its intended shaping purpose by setting appropriate time, temperature, and pressure.

[0003] Due to their varying shapes, existing workpieces require specific hot press fixtures or specialized tooling to meet the hot pressing requirements. For example, hot pressing a U-shaped workpiece requires pressing both sides of the U, necessitating simultaneous clamping and fixing of both sides. However, existing hot press equipment cannot clamp or hot press workpieces that are parallel to each other. Utility Model Content

[0004] The purpose of this utility model is to provide a hot press clamping fixture, which aims to solve the problem that existing hot press clamps or equipment cannot be used for workpieces with double layers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hot-press clamping fixture, comprising:

[0007] The lifting mechanism includes a first clamping unit and a second clamping unit. The first clamping unit includes a first lifting rod that passes through the base, a first pushing block disposed on the first lifting rod, and a first clamping block that slides in cooperation with the first pushing block and moves toward or away from the first vertical clamping plate.

[0008] The second clamping unit includes a second lifting rod that passes through the base, a second pushing block disposed on the second lifting rod, and a second clamping block that slides in cooperation with the second pushing block and moves toward or away from the second vertical clamping plate.

[0009] Preferably, a linkage rod is provided between the first lifting rod and the second lifting rod, and a slide rod is provided on the linkage rod for its own lifting and sliding, with one end of the slide rod being disposed on the base.

[0010] Preferably, a retaining ring is provided on the other end of the linkage rod, and a power unit is provided on the linkage rod to drive its own lifting and moving movement.

[0011] Preferably, the base is provided with at least one first guide rod arranged parallel to the first lifting rod, and the first pushing block is provided with a guide groove or guide hole that slides and engages with the first guide rod.

[0012] Preferably, the top abutment surface of the sliding engagement between the first pushing block and the first clamping block is an inclined surface;

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a hot-press clamping fixture, including a base 10 and a lifting mechanism 20. The base 10 is provided with a first vertical clamping plate 11 and a second vertical clamping plate 12 arranged parallel to the first vertical clamping plate 11. The lifting mechanism 20 includes a first clamping unit 21 and a second clamping unit 22. The first clamping unit 21 includes a first lifting rod 211 penetrating the base 10, a first pushing block 212 disposed on the first lifting rod 211, and a first clamping block 213 that slides in cooperation with the first pushing block 212 and moves toward or away from the first vertical clamping plate 11. The second clamping unit 22 includes a second lifting rod 221 penetrating the base 10, a second pushing block 222 disposed on the second lifting rod 221, and a second clamping block 223 that slides in cooperation with the second pushing block 222 and moves toward or away from the second vertical clamping plate 12.

[0038] Specifically, when hot pressing a workpiece with two parallel planar structures, the first clamping unit 21 cooperates with the first vertical clamping plate 11 to clamp and hot press one of the planes of the workpiece, while the second clamping unit 22 clamps with the second vertical clamping plate 12 to clamp and hot press the other plane of the workpiece. This forms a double-sided synchronous hot pressing process for the workpiece, ensuring uniform hot pressing and improving processing accuracy and efficiency.

[0039] In use, the first lifting rod 211 and the second lifting rod 221 are driven to rise synchronously, which in turn drives the first pushing block 212 and the second pushing block 222 to move. This causes the first clamping block 213 to move closer to the first vertical clamping plate 11 until it is clamped, and the second clamping block 223 to move closer to the second vertical clamping plate 12 until it is clamped. This forms a state of tightly clamping both sides of the workpiece, and then the workpiece is simultaneously hot-pressed on both sides to ensure that the workpiece is heated evenly and improve the hot-pressing effect.

[0040] like Figure 2 and Figure 3As shown, in this embodiment, a linkage rod 30 is provided between the first lifting rod 211 and the second lifting rod 221. The linkage rod 30 is equipped with a sliding rod 31 for its own lifting and lowering, with one end of the sliding rod 31 mounted on the base 10. Thus, through the coordinating action of the linkage rod 30, the two lifting rods can be raised or lowered synchronously. This synchronous control ensures consistent clamping force and prevents workpiece deformation.

[0041] Furthermore, such as Figure 2 As shown, in this embodiment, a retaining ring 32 is provided on the other end of the linkage rod 30. The linkage rod 30 is equipped with a power unit that drives its own lifting and lowering movement. The power unit can be a pneumatic cylinder or a hydraulic cylinder. Specifically, the retaining ring 32 limits the linkage rod 30, ensuring it will not disengage during lifting and lowering, thus ensuring stable lifting and lowering movement. Furthermore, the power unit drives the lifting stroke, enabling precise adjustment of the clamping force and further improving the workpiece's processing quality.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment, the base 10 is provided with at least one first guide rod 13 arranged parallel to the first lifting rod 211, and the first pushing block 212 is provided with a guide groove 2121 or a guide hole that slides and engages with the first guide rod 13. The guide groove 2121 on the first guide rod 13 ensures that the first pushing block 212 moves smoothly along the guide rod, providing stable support for the first pushing block 212 to ensure stable lifting and lowering movement, and also ensuring a stable pushing force for the first clamping block 213.

[0043] like Figure 5 and Figure 6 As shown, in this embodiment, the top abutting surface of the sliding engagement between the first pushing block 212 and the first clamping block 213 is an inclined surface 2122; an inverted T-shaped protrusion 2123 is provided on the inclined surface 2122 of the first pushing block 212, and a sliding groove 2131 is provided on the first clamping block 213 to slide and engage with the inverted T-shaped protrusion 2123.

[0044] Specifically, through the design of the inclined surface 2122 and the cooperation of the inverted T-shaped protrusion 2123 and the slide groove 2131, the pushing action of the first pushing block 212 and the first clamping block 213 on the inclined surface 2122 is more stable, avoiding deviation caused by horizontal movement. This ensures that the first pushing block 212 drives the first clamping block 213 to move laterally, ensuring that the workpiece remains stable during hot pressing, and further improving processing accuracy and efficiency.

[0045] like Figure 4As shown, in this embodiment, a second guide rod 14 is also provided on the base 10, a first groove 2132 that slides and engages with the second guide rod 14 is provided on the inclined surface 2122 of the first clamping block 213, and a second groove 2124 that slides and engages with the second guide rod 14 is provided on the inclined surface 2122 of the first pushing block 212.

[0046] Specifically, the design of the second guide rod 14 can ensure that the second push block 222 moves smoothly along the guide rod and provide stable support to ensure that the second push block 222 moves stably up and down, and can also ensure that it provides stable support force for the second clamping block 223 to avoid the second clamping block 223 from tilting during the clamping process, and ensure that the workpiece remains horizontal and stable during the hot pressing process.

[0047] like Figure 5 and Figure 6 As shown, in this embodiment, the top surface of the second clamping block 223 is provided with an adjusting slide rail 2231 and an adjusting block 2232 disposed on the adjusting slide rail 2231. The design of the adjusting block 2232 increases the clamping area and horizontal height of the second clamping block 223, thereby further improving the stability and uniformity of clamping, ensuring uniform force on the workpiece during hot pressing, and improving the quality of hot pressing. Furthermore, by adjusting the position of the slider, the clamping force can be flexibly adjusted to adapt to different workpiece requirements, optimize the hot pressing effect, and ensure a comprehensive improvement in processing accuracy and efficiency. The fine-tuning function of the slider precisely controls the clamping force, adapting to workpieces of different materials and thicknesses, ensuring no displacement during hot pressing, and improving the quality of the finished product. Simultaneously, the slider design facilitates quick replacement, improving production efficiency and meeting diverse processing needs.

[0048] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
