Specific implementation

[0028] The utility model will be further described below in conjunction with the embodiment shown in the drawings.

[0029] As Figures 1-4 shown, it is the structural schematic view of the air-cooled shaping and pressing fixture of the utility model, and the fixture includes support frame, pressing plate 7, pressing assembly, bearing assembly and cooling assembly.Support frame mainly plays the role of supporting and fixing, and the support frame includes foot pad 1, bottom plate 2, support column 3 and top plate 4.The bottom plate 2 is rectangular metal plate, and the foot pad 1 is at least four, which is fixed on the bottom of the bottom plate 2 by screw fastening.

[0030] At least four foot pads 1 support the bottom plate 2, avoid the bottom plate 2 from rusting due to the water accumulation on the workbench.At least four foot pads 1 are distributed at the four corners of the bottom of the bottom plate 2, which can improve the stability of the overall structure and avoid the fixture from shaking during shaping and pressing, thereby affecting the shaping effect.

[0031] The support column 3 is fixed on the top of the bottom plate 2 by welding, and the top plate 4 is fixed on the top of the support column 3 by welding.The support column 3 is at least four, and is distributed at the four corners of the top of the bottom plate 2, which improves the stability and structural strength of the top plate 4.

[0032] The cylinder body of the lifting cylinder 8 is fixed on the upper surface of the top plate 4 by screw fastening, and the piston rod of the lifting cylinder 8 penetrates through the top plate 4 and is connected with the pressing plate 7, the pressing plate 7 is driven to descend by the lifting cylinder 8, and then the shaping and pressing of the product are completed by the pressing assembly at the bottom of the pressing plate 7.

[0033] The guide sleeve 5 is embedded on the top of the top plate 4, the guide column 6 is fixed on the top of the pressing plate 7 and penetrates the guide sleeve 5, when the pressing plate 7 is lifted by the lifting cylinder 8, the guide sleeve 5 and the guide column 6 are arranged to improve the stability of the movement of the pressing plate 7, and then improve the effect of shaping and pressing (specifically, a through hole is formed on the top plate 4, the guide sleeve 5 is embedded in the through hole, and then the guide sleeve 5 is fixed on the top of the top plate 4 by screwing).

[0034] The pressing assembly is arranged on the bottom of the pressing plate 7, and is used to shape and press the product under the driving of the lifting cylinder 8. The pressing assembly comprises a threaded rod 9 and a pressing head 10. The threaded hole penetrates the pressing plate 7, and the threaded hole has at least two, so the threaded rod 9 and the pressing head 10 which are matched with the threaded hole also have at least two. In actual pressing, at least two pressing heads 10 press on the product to be shaped, the stress is more uniform, and the shaping effect is better.

[0035] The threaded rod 9 is screwed in the threaded hole of the pressing plate 7, and the pressing head 10 is fixed on the bottom of the threaded rod 9. In actual pressing, the pressing plate 7 is lowered by the lifting cylinder 8, and then the threaded rod 9 and the pressing head 10 are lowered to shape and press the product carried on the carrying assembly. By arranging the threaded rod 9 and the threaded hole, the threaded rod 9 can be screwed to adjust the initial height position of the pressing head 10, so as to adjust the pressing force and improve the versatility of the pressing jig.

[0036] The carrying assembly is adjustably arranged on the top of the bottom plate 2, and is used to carry the product to be shaped and pressed. As shown in Figure 5 , 6 , the carrying assembly comprises an adjusting groove 12, a stop block 13, a fixing hole 14, a profiling groove 15, an arc-shaped part 16, an avoiding hole 17 and an avoiding groove 18. The stop block 13 has two and is oppositely arranged on the top of the bottom plate 2. The profiling groove 15 is formed on the opposite side of the stop block 13 (i.e. the inner side of the two stop blocks 13) and is used to receive the product to be shaped and pressed (the profiling groove 15 is matched with the shape of the product).

[0037] As shown in Figure 3 , the adjusting groove 12 penetrates the bottom plate 2, and the adjusting groove 12 is in a round rectangular shape. The fixing hole 14 has at least two and is formed on the bottom of the stop block 13 and matched with the adjusting groove 12. In actual fixing, the fastening bolt is screwed in the fixing hole 14 through the adjusting groove 12 to realize the fixing of the stop block 13 and the bottom plate 2. By arranging the adjusting groove 12, the position of the stop block 13 can be adjusted, and then the position of the pressing head 10 pressing on the product is adjusted to realize the shaping and pressing at different positions.

[0038] The avoiding hole 17 and the avoiding groove 18 are formed on the bottom of the profiling groove 15 and are used to avoid the reinforcing ribs and protrusions on the bottom of the product. The arc-shaped part 16 is arranged on the inner side of the stop block 13 to facilitate the operator to put the product into the profiling groove 15.

[0039] Since the inner side of the block 13 is provided with a profiling groove 15 matched with the shape of the product, the outer side of the block 13 is formed with a retaining wall structure to block and position the shaped product.

[0040] The cooling assembly is a fan 11 which is fixed on the top of the bottom plate 2 by screwing and faces the product to be shaped and compressed. While shaping and compressing the product, the product is cooled by air cooling to make it quickly set, improve the shaping efficiency, and avoid the problem of springback after compression to cause rework.

[0041] In the shaping process of the air cooling shaping and compressing jig, the product is shaped in the jig after production in a hot state. The lifting cylinder 8 and the fan 11 are started, the descending pressure head 10 shapes and compresses the product, and the air cooling cools and sets the product, improves the shaping efficiency, avoids the problem of springback after compression to cause rework, effectively improves the work efficiency, replaces the manual work, avoids the problem of product breakage or damage, controls the problems of deformation degree springback or shaping misplacement, and repeatedly circulates the above process.
