DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The embodiment of the processing device of a C-type block of the utility model is as follows Figures 1 to 9As shown. The device includes a base 1, on which a mold 4 is provided. In this embodiment, the mold 4 is a rectangular parallelepiped with a certain length, and a through hole extending in the length direction is provided inside the mold 4. A round tube is input at one end of the through hole of the mold 4, and the round tube is made into a square tube after being shaped by the mold 4 and output from the other end of the through hole. The end of the through hole of the mold 4 for inputting the round tube is round, and the end for outputting the square tube is square. The shape of the through hole of the mold 4 gradually changes from round to square from the input end to the output end. The input end of the mold through hole is a circle that matches the round tube, and the output end is a square that matches the square tube after the round tube is shaped, as shown Figure 2 、 Figure 4 、 Figure 5 As shown, the middle position of the mold through hole is an arc-shaped square hole. Figure 3 As shown, the through hole has a smooth transition.

[0028] Multiple roller groups are distributed on the inner wall of the mold through hole in the extension direction of the through hole. Each roller group includes multiple first rollers 402 distributed around the axis of the through hole. The first rollers 402 are rotatably set in the roller groove 406 on the inner wall of the through hole and the outer circumferential surface of the first rollers 402 protrudes from the roller groove 406. The first rollers 402 are flat cylindrical and the outer circumferential surface is an outward convex arc. The line connecting the convex vertices of each first roller 402 in each roller group is parallel to the outer circumference of the through hole cross section where the roller group is located. Figures 2 to 4 As shown. A second roller 405 is provided on the inner wall at the opening of the mold through-hole output end. The second roller 405 is cylindrical. The opening of the mold through-hole output end is square. A second roller 405 is provided on the inner wall corresponding to each side of the square through-hole. The length of the second roller 405 matches the length of the inner wall. The second roller 405 further reshapes the square tube as it exits the mold, so that the shape of the square tube meets the requirements.

[0029] Under the action of external force, the round tube is pushed into the through hole. As the round tube enters, it is gradually rolled from a round shape into a square tube by the first roller 402 and the second roller 405. The first roller 402 and the second roller 405 are driven and rotated by the round tube and the square tube under the action of external force, which can reduce the resistance of the round tube and the square tube to pass through.

[0030] A thrust device 2 for applying thrust to the round tube is provided on one side of the input end of the mold 4. In this embodiment, the thrust device 2 adopts a hydraulic cylinder, and a push block 202 is provided at the end of the first output shaft 201 of the hydraulic cylinder. After one end of the round tube is initially inserted into the through hole, the hydraulic cylinder is started so that the push block 202 is pressed against the round tube. Under the thrust of the hydraulic cylinder, the round tube is pushed into the through hole of the mold until the push block 202 is pressed against the end face of the input end of the mold. At this time, the other end of the round tube has been pressed into a square tube and extends out of the output end face of the mold.

[0031] A pulling device 3 for applying pulling force to the round tube is provided on one side of the output end of the mold 4. In this embodiment, the pulling device 2 may also be a hydraulic cylinder. A clamping device 302 is provided at the end of the second output shaft 301 of the hydraulic cylinder. The clamping device 302 may be a four-jaw chuck, which may clamp the outer sides of the four sides of the square tube extending out of the end face of the output end of the mold. After clamping, the second output shaft 301 of the hydraulic cylinder contracts to pull the shaped square tube out of the mold 4. After pulling out, the entire round tube is completely rolled into a square tube.

[0032] The base 1 is equipped with a round tube placement platform 5 and a square tube placement platform 6. The round tube placement platform 5 is located near the input end of the mold 4, while the square tube placement platform 6 is located near the output end of the mold 4, facilitating easy handling. The square tube placement platform 6 is provided with multiple parallel cutting grooves 601. When a square tube is placed on the placement platform 6 and cut, the saw blade can enter the cutting grooves 601 and avoid the placement platform 6, preventing damage to the placement platform 6. To cut a square tube into multiple square tubes at once, the placement platform 6 is provided with multiple parallel cutting grooves 6.

[0033] A lifting bracket 7 is provided above the square tube placement table 6, and the lifting bracket 7 is provided on the base 1. A lifting device 8 is vertically provided on the lifting bracket 7. In the present embodiment, the lifting device 8 adopts a hydraulic cylinder, and a cutting bracket 9 is provided at the end of the third output shaft 801 of the hydraulic cylinder. Under the action of the hydraulic cylinder, the cutting bracket 9 can be lifted and lowered. A rotating shaft 10 is provided on the cutting bracket 9. The projection of the rotating shaft 10 on the square tube placement table 6 is perpendicular to the cutting groove 601. A plurality of saw blades 11 corresponding to the cutting grooves 601 are distributed on the rotating shaft 10. A rotating device for driving the rotating shaft 10 to rotate is provided on the cutting bracket 9. In the present embodiment, the rotating device adopts a cutting motor 12, and the output shaft of the cutting motor 12 is connected to the rotating shaft 10 to drive the rotating shaft 10 to rotate.

[0034] A segmented cutting fixture 13 is installed on both sides of the square tube placement platform 6. In this embodiment, the segmented cutting fixture 13 is a hydraulic cylinder. The fourth output shaft 1301 of the hydraulic cylinder is perpendicular to the cutting groove 601, and a segmented cutting fixture block 1302 is installed at its end. The segmented cutting fixture blocks 1302 of the segmented cutting fixture 13 on both sides move relative to each other, clamping the square tube. The cutting motor 12 then drives the saw blade to rotate and the cutting bracket 8 to descend. The saw blade 11 cuts the square tube into multiple segments. After cutting is completed, the cutting bracket 8 is raised, and the saw blade stops rotating.

[0035] The other two sides of the square tube placement platform 6 are equipped with slotting and cutting fixtures 14. In this embodiment, these fixtures are hydraulic cylinders. The fifth output shaft 1401 of the hydraulic cylinder is parallel to the cutting groove 601, and a slotting and cutting fixture block 1402 is located at its end. The slotting and cutting fixture blocks 1402 are of a predetermined length. Multiple cut square tube segments are sequentially placed on the square tube placement platform 6, with a square tube parallel to each cutting groove 601 placed above each cutting groove 601. The slotting and cutting fixtures 1402 are then activated, allowing the slotting and cutting fixture blocks 1402 on both sides to simultaneously contact the square tubes above each cutting groove 601, securing the tubes. Furthermore, the slotting and cutting fixture blocks 1402 are positioned relatively low, below the top surface of the tubes, to prevent interference with the saw blade during cutting and, consequently, damage to the slotting and cutting fixture blocks 1402. Once the multiple square tube segments are secured, the saw blade 11 is activated, and the cutting bracket 9 is lowered, cutting a slot through the top surface of the square tube 15 along its length. In order to enable the saw blade 11 to completely cut a groove on the upper surface of the square tube in the length direction, during the cutting process, the fifth output shaft 1401 of the slotting cutting fixture 14 on one side is extended, and the fifth output shaft 1401 of the slotting cutting fixture 14 on the other side is retracted. The square tube 15 can be clamped while the square tube is moved, so that the saw blade can cut the entire square tube 15.

[0036] The round tube is rolled by the roller and extruded in the mold 4 to finally be formed into a square tube. Then the square tube 15 is fixed and cut into multiple sections by the saw blade 11. Then, the saw blade 11 is cut into C-shaped blocks to complete the processing.

[0037] In other embodiments, a screw structure or a linear motor, a cylinder, etc. may be used to replace the hydraulic cylinder in the above embodiment, and a hydraulic motor or other device may be used to replace the cutting motor 12.

[0038] The device of the utility model is used to roll and cut the round tube, which is simple to process, fast in processing speed, short in processing cycle and low in cost; and the processed C-shaped block is not only regular in block shape, but also has higher strength, smoother workpiece surface and fewer burrs than the C-shaped block made by casting.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
