[0001] The utility model relates to the technical field of cold bending forming machines, in particular to a forming roll installation structure of a cold bending forming machine. Background Art

[0002] A cold bending forming machine is a machine for the plastic processing technology that continuously transversely bends metal strip materials such as coils and strips through a series of sequentially arranged forming rolls to form profiles with specific cross-sections. The pipe fittings of a cold bending forming machine are the forming rolls.

[0003] At present, the forming roll of a cold bending forming machine includes a shaft rod in the middle and a roll body fixed on the surface of the shaft rod. When installing, it is necessary to fixedly connect both ends of the shaft rod with the driving shafts on the frame. The existing connection method is to use the cooperation of bolts and screw holes for fixed connection. When maintaining and disassembling later, special tools are required for disassembly, and the installation and disassembly are not fast and convenient enough. Secondly, the shaft rod and the roll body are an integral structure. During the long-term extrusion forming process, the shaft rod may bend. At this time, only the shaft rod and the roll body can be replaced together, resulting in material waste. Therefore, the utility model proposes a forming roll installation structure of a cold bending forming machine. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a forming roll installation structure of a cold bending forming machine.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A forming roll installation structure of a cold bending forming machine, including a frame, a horizontal shaft, and an extrusion roll. An axial groove for passing through the horizontal shaft is opened in the middle of the extrusion roll. The extrusion roll is sleeved on the surface of the horizontal shaft and is slidably connected with the horizontal shaft. A convex ring is fixed on the surface of one end of the extrusion roll. An internal thread sleeve is sleeved on the surface of the convex ring. A through hole is opened at one end of the internal thread sleeve close to the extrusion roll. The through hole is slidably connected with the surface of the extrusion roll, and the diameter of the through hole is smaller than the diameter of the convex ring. An external thread connection part for connecting the internal thread sleeve is provided on the surface of the horizontal shaft. Both sides of the frame are rotatably connected with rotating shafts through bearings, and connecting components for connecting the horizontal shaft are fixed at adjacent ends of the two rotating shafts.

[0006] Further, one end of the internal thread sleeve close to the external thread connection part is designed to be open, and the internal thread sleeve is rotatably connected to the surface of the external thread connection part.

[0007] Further, a convex block is fixed on the surface of the middle part of the horizontal shaft. A sliding groove is opened on the inner wall of the extrusion roll and close to the convex ring. The convex block is located inside the sliding groove and is slidably connected with the sliding groove.

[0008] Further, the connecting component includes a shaft rod fixedly connected to the rotating shaft. A groove is formed at one end of the shaft rod away from the rotating shaft. A spring is fixedly connected to the inner wall of the groove, and the other end of the spring is fixedly connected to a clamping rod. Clamping grooves for clamping the clamping rod are formed at both ends of the horizontal shaft.

[0009] Further, both the clamping groove and the clamping rod are of square structures.

[0010] Further, strip-shaped openings are formed on both sides of the groove. A sleeve is slidably connected to the surface of the shaft rod outside the strip-shaped openings. Two connecting rods are fixed to the inner wall of the sleeve. The two connecting rods respectively pass through the two strip-shaped openings and are fixedly connected to the clamping rod.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. When the present utility model is in use, for the forming roller mounting structure of a cold bending forming machine, a frame, a horizontal shaft, an extrusion roller and two rotating shafts are provided. The two rotating shafts are rotatably connected to both sides of the frame through bearings, and connecting components are fixed to adjacent ends of the two rotating shafts. The extrusion roller is fixed to the middle of the horizontal shaft, and both ends of the horizontal shaft can be quickly fixedly connected to the rotating shafts through the connecting components, so as to realize the installation of the forming roller. Special tools are not required for disassembly during later maintenance, making the maintenance simpler and more convenient.

[0013] 2. When the present utility model is in use, for the forming roller mounting structure of a cold bending forming machine, an internal thread sleeve and an external thread connecting part are provided. The internal thread sleeve is slidably sleeved on the surface of one end of the extrusion roller. By screwing the internal thread sleeve onto the surface of the external thread connecting part, the quick fixed connection between the extrusion roller and the horizontal shaft is realized. Therefore, for this forming roller structure, the extrusion roller and the horizontal shaft are separable. When the horizontal shaft is deformed, the horizontal shaft can be replaced separately, avoiding material waste. Description of the Drawings

[0022] As Figures 1-4 shown, it relates to a forming roller mounting structure of a cold bending forming machine, including a frame 1, a horizontal shaft 2 and an extrusion roller 3. An axial slot for passing through the horizontal shaft 2 is provided in the middle of the extrusion roller 3. The extrusion roller 3 is sleeved on the surface of the horizontal shaft 2 and is slidably connected to the horizontal shaft 2. A convex ring 31 is fixed on the surface of one end of the extrusion roller 3. An internal thread sleeve 4 is sleeved on the surface of the convex ring 31. A perforation 41 is provided at one end of the internal thread sleeve 4 close to the extrusion roller 3. The perforation 41 is slidably connected to the surface of the extrusion roller 3, and the diameter of the perforation 41 is smaller than the diameter of the convex ring 31. An external thread connection part 5 for connecting the internal thread sleeve 4 is provided on the surface of the horizontal shaft 2. Rotating shafts 6 are rotatably connected to both sides of the frame 1 through bearings, and connection assemblies 7 for connecting the horizontal shaft 2 are fixed to adjacent ends of the two rotating shafts 6.

[0023] One end of the internal thread sleeve 4 close to the external thread connection part 5 is designed to be open, and the internal thread sleeve 4 is rotatably connected to the surface of the external thread connection part 5.

[0024] After the extrusion roller 3 is sleeved on the surface of the horizontal shaft 2, the internal thread sleeve 4 can be screwed onto the surface of the external thread connection part 5, so as to realize the fixed connection between the extrusion roller 3 and the horizontal shaft 2.

[0025] A protrusion 21 is fixed on the surface of the middle part of the horizontal shaft 2. A slide groove 32 is provided on the inner wall of the extrusion roller 3 and on one side close to the convex ring 31. The protrusion 21 is located inside the slide groove 32 and is slidably connected to the slide groove 32.

[0026] By engaging the protrusion 21 into the inside of the slide groove 32, the extrusion roller 3 can be driven to rotate synchronously when the horizontal shaft 2 rotates.

[0027] The connecting component 7 includes a shaft rod 71 fixedly connected to the rotating shaft 6. A groove 72 is formed at one end of the shaft rod 71 away from the rotating shaft 6. A spring 73 is fixedly connected to the inner wall of the groove 72, and the other end of the spring 73 is fixedly connected to a clamping rod 74. Claw slots 22 for clamping the clamping rod 74 are formed at both ends of the horizontal shaft 2.

[0028] When the claw slot 22 at the end of the horizontal shaft 2 is aligned with the clamping rod 74 of the connecting component 7, the spring 73 can push the clamping rod 74 into the inside of the claw slot 22, thereby fixing the horizontal shaft 2 between the two rotating shafts 6.

[0029] Both the claw slot 22 and the clamping rod 74 are square structures.

[0030] Both the claw slot 22 and the clamping rod 74 adopt square structures, which is convenient for the rotating shaft 6 to drive the horizontal shaft 2 to rotate synchronously.

[0031] Strip-shaped openings 76 are formed on both sides of the groove 72. A sleeve 75 is slidably connected to the surface of the shaft rod 71 and outside the strip-shaped openings 76. Two connecting rods 77 are fixed to the inner wall of the sleeve 75, and the two connecting rods 77 respectively pass through the two strip-shaped openings 76 and are fixedly connected to the clamping rod 74.

[0032] Sliding the sleeve 75 along the surface of the shaft rod 71, the sleeve 75 can drive the clamping rod 74 to retract into the groove 72 through the connecting rod 77. When the clamping rod 74 is disengaged from the claw slot 22, the horizontal shaft 2 can be disassembled from between the two rotating shafts 6. Therefore, the disassembly of the horizontal shaft 2 can be realized without special tools.

[0033] Working principle: When installing the extrusion roller 3, the extrusion roller 3 is sleeved on the surface of the horizontal shaft 2 from one end away from the external thread connection part 5, and the convex block 21 is engaged into the sliding groove 32. Then, the internal thread sleeve 4 is screwed onto the surface of the external thread connection part 5 to realize the fixed connection between the extrusion roller 3 and the horizontal shaft 2. Then, the sleeves 75 on the surfaces of the two shaft rods 71 are slid, and the sleeves 75 are used to drive the clamping rods 74 to retract into the grooves 72. Then, the claw slots 22 at both ends of the horizontal shaft 2 are aligned with the clamping rods 74 at both ends. Subsequently, after releasing the sleeves 75, the spring 73 squeezes the clamping rods 74 into the claw slots 22 to realize the fixed installation of the horizontal shaft 2. When the forming machine works, the rotating shaft 6 is started to rotate by the driving motor.
