Description

Technical Field

[0001] This invention relates to the field of air compressor processing, and particularly to a mold for processing screw air compressors. Background Technology

[0002] Screw air compressors are mostly used in factories that require high-pressure gas. During the production of air compressors, a large number of bent steel pipes are needed for support. The steel pipes are straight after leaving the factory and need to be bent before they can be used.

[0003] To address this, a die for processing screw-type air compressors, such as the one with patent number CN221086855U, was developed. This equipment can consistently limit the steel pipe during the bending process, preventing it from rolling or shifting, thus ensuring the quality of the bending. It is also suitable for bending steel pipes of varying lengths within a limited range, and can be used for processing sheet metal. However, this equipment still has the following drawbacks: bending a single steel pipe significantly affects processing efficiency; and because the steel pipe has a circular structure, it is difficult to guarantee that the pipe will not roll on the base during the bending process even with the clamping of two sets of U-shaped plates. Summary of the Invention

[0004] The purpose of this invention is to provide a mold for processing screw air compressors.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A mold for processing a screw air compressor includes a base, a bending groove on the top of the base, and a bending block driven vertically by a hydraulic rod I directly above the bending groove.

[0007] The top of the base on both sides of the bending groove is provided with a strip groove. The top of the base is uniformly provided with slots connecting the strip groove and the bending groove. The bottom of the slot is higher than the bottom of the strip groove. A clamping plate is also provided in the strip groove. A screw extending into the corresponding strip groove is provided on the outside of the base. The end of the screw is movably connected to the back of the corresponding clamping plate through a bearing. Mounting plates are also provided on both sides of the top of the base. A fixing plate is suspended above the base between the two sets of mounting plates. The two sets of strip grooves are located between the two sets of fixing plates. A hydraulic rod II for horizontally driving the fixing plate is provided on the mounting plate. A U-shaped notch corresponding to the slot is provided at the top of the fixing plate.

[0008] Preferably, the bending groove and the strip groove are arranged in parallel, the slot is arranged perpendicularly to the bending groove and the strip groove, and the vertical cross-section of the slot is a U-shaped structure.

[0009] Preferably, a sliding groove is provided on the bottom wall of the strip groove, which is perpendicular to the clamping plate, and a slider extending into the sliding groove is provided on the clamping plate.

[0010] Preferably, the base sidewall is provided with a screw hole for screwing the screw, the end of the screw is provided with a gripping part, and the screw and the clamp are arranged perpendicularly.

[0011] Preferably, the fixing plate is located above the clamping plate, the size of the U-shaped notch is equal to the size of the slot, and the back of the fixing plate is also provided with a fixing rod that penetrates the through hole on the mounting plate.

[0012] Preferably, the bending groove has an inverted equilateral triangle cross section, the bending block and the bending groove are matched in size, the base is provided with a frame for fixing the hydraulic rod I, the bottom of the hydraulic rod I is provided with a base, and the bending block is fixed to the bottom of the base by bolts.

[0013] The beneficial effects of this invention are: This invention uses two sets of clamps and slots to position multiple sets of steel pipes, preventing them from moving horizontally, thereby improving the bending effect and processing efficiency of the steel pipes. In addition, during the bending process, the moving fixing plate drives the U-shaped notch to fasten to the bottom of the raised end of the steel pipe, thereby limiting the steel pipe and preventing it from swinging during the subsequent bending process, thus further improving the bending effect of the steel pipe.

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] A mold for processing a screw air compressor includes a base 1. A bending groove 2 is provided on the top of the base 1. A bending block 3, driven vertically by a hydraulic rod I4, is provided directly above the bending groove 2. The bending groove 2 has an inverted equilateral triangle structure in cross-section. The bending block 3 is adapted to the size of the bending groove 2. A frame 16 for fixing the hydraulic rod I4 is provided on the base 1. A base 17 is provided at the bottom of the hydraulic rod I4. The bending block 3 is fixed to the bottom of the base 17 by bolts.

[0019] The top of the base 1 on both sides of the bending groove 2 is provided with a strip groove 5. The top of the base 1 is provided with a slot 6 that connects the strip groove 5 and the bending groove 2. The bottom of the slot 6 is higher than the bottom of the strip groove 5. A clamping plate 7 is also provided in the strip groove 5. A screw 8 extending into the corresponding strip groove 5 is provided on the outside of the base 1. The end of the screw 8 is movably connected to the back of the corresponding clamping plate 7 through a bearing 9. A screw hole for screwing the screw 8 is provided on the side wall of the base 1. A gripping part is provided at the end of the screw 8. The screw 8 and the clamping plate 7 are arranged perpendicularly.

[0020] The base 1 is also provided with mounting plates 10 on both sides of the top. A fixing plate 11 is suspended above the base 1 between the two sets of mounting plates 10, and two sets of strip grooves 5 are located between the two sets of fixing plates 11. A hydraulic rod II13 for horizontally driving the fixing plate 11 is provided on the mounting plate 10. A U-shaped notch 12 corresponding to the slot 6 is provided at the top of the fixing plate 11.

[0021] In this embodiment, the bending groove 2 and the strip groove 5 are arranged in parallel, and the slot 6 is arranged perpendicularly to the bending groove 2 and the strip groove 5. The vertical cross-section of the slot 6 is a U-shaped structure.

[0022] In this embodiment, a sliding groove 14 is provided on the bottom wall of the strip groove 5, which is perpendicularly intersecting the clamping plate 7, and a slider extending into the sliding groove 14 is provided on the clamping plate 7.

[0023] like Figure 1 As shown, the fixing plate 11 is located above the clamping plate 7, the U-shaped notch 12 is the same size as the slot 6, and the back of the fixing plate 11 is also provided with a fixing rod 15 that penetrates the through hole on the mounting plate 10.

[0024] In use, the steel pipe is placed above the bending groove 2, with both ends inserted into the corresponding slots 6. The end of the steel pipe extends into the corresponding strip groove 5. By rotating the screw 8, which rotates within the screw hole and on the bearing 9, the clamping plate 7 is pushed towards the end of the steel pipe. This achieves the purpose of clamping and fixing both ends of the steel pipe by adjusting the position of the clamping plate 7 in the strip groove 5, preventing it from moving left or right. At the same time, the slots 6 fix the steel pipe, preventing it from moving back and forth.

[0025] When in use, hydraulic rod I4 drives base 17 and moves bending block 3 downward, thereby bending the steel pipe suspended in bending groove 2 by pressing it downward. When the two ends of the steel pipe bend and tilt upward during the bending process, when its end is higher than fixed plate 11, hydraulic rod II13 drives fixed plate 11 to move towards the steel pipe, so that it drives U-shaped notch 12 to slide to the bottom of the tilted end of the steel pipe, and the U-shaped notch 12 is fastened to the bottom of the tilted end of the steel pipe, thus limiting the steel pipe and preventing it from swinging during subsequent bending. As the distance between the two tilted ends of the steel pipe gradually decreases, the distance between the two sets of fixed plates 11 also decreases, so that the U-shaped notch 12 is always fastened to the bottom of the tilted end of the steel pipe to provide positioning.

[0026] The present invention uses two sets of clamping plates 7 and slots 6 to position multiple sets of steel pipes, preventing them from moving horizontally, thereby improving the bending effect and processing efficiency of the steel pipes. During the bending process, the moving fixing plate 11 drives the U-shaped notch 12 to lock onto the bottom of the raised end of the steel pipe, thereby limiting the steel pipe and preventing it from swinging during the subsequent bending process, thus further improving the bending effect of the steel pipe.

[0027] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
