Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, specifically to a traction device for automotive aluminum profiles. Background Technology

[0002] When cutting long strips of aluminum in an automotive manufacturing plant, the strips need to be pulled forward continuously and then cut into sections. The current method of manually pulling and traction is time-consuming, labor-intensive, and extremely inefficient. The method of using equipment for traction is also problematic because its structural design is unreasonable, which can easily cause the long strips of aluminum to fall off during the traction process, and its adaptability is not high enough.

[0003] Application number 201921284827.4 discloses a traction device for automotive aluminum profiles, including a roller production line, a linear slide rail module production line, a connecting part, and a traction head. The roller production line supports and holds long aluminum profiles, which extend along the length of the roller production line. The traction head is fixedly connected to a slider assembly on the linear slide rail module production line via the connecting part, and the traction head clamps and fixes one end of the long aluminum profile. The linear slide rail module production line can drive the traction head to move the long aluminum profile along the roller production line. This invention discloses a traction device for automotive aluminum profiles, capable of traction of long aluminum profiles of different thicknesses, improving its adaptability and processing efficiency.

[0004] However, there are shortcomings. This utility model moves the aluminum profile by having a traction head move on a slide rail. Once the aluminum profile is cut, it loses its traction effect. This requires the traction head to move back and forth continuously to achieve normal traction of the aluminum profile, resulting in low work efficiency. Alternatively, the number of traction heads can be increased to achieve the purpose of continuously pulling the aluminum profile, which would increase production costs. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a traction device for automotive aluminum profiles, comprising a frame and a mounting frame. Support legs are fixedly connected to the four corners of the lower surface of the frame. Several conveying rollers are rotatably mounted inside the frame. The mounting frame is fixedly mounted on the upper surface of the frame and includes a traction mechanism. The traction mechanism comprises two conveying rollers and an extrusion cylinder. The conveying rollers are located in the middle of the frame, and the extrusion cylinder is located inside the mounting frame. Two mounting holes and two arc-shaped grooves are symmetrically formed on the two side walls of the mounting frame. A drive column is rotatably mounted inside the mounting holes. A rotating shaft is fixedly connected to both ends of the extrusion cylinder. The rotating shaft is slidably disposed within the arc-shaped groove. A belt is drively connected to the end of the rotating shaft located inside the mounting frame. The end of the belt away from the rotating shaft is drively connected to the drive column. A mounting cylinder is fixedly connected to the end of the rotating shaft away from the extrusion cylinder. A screw is rotatably mounted inside the extrusion cylinder, rotating shaft, and mounting cylinder. The threads at both ends of the screw are in opposite directions. A handwheel is fixedly installed at one end of the screw. Two movable slots are symmetrically opened in the middle of the two side walls of the frame. An arc-shaped block is slidably arranged inside the movable slot. A spring is fixedly installed between the lower surface of the arc-shaped block and the bottom inner wall of the movable slot. A movable slot is opened in the middle of one side wall of the frame. The movable slot is located between the two movable slots. Both ends of the conveying roller are fixedly connected to round shafts. The round shafts are slidably arranged inside the movable slots. The arc-shaped block is located at the bottom of the round shaft. The ends of the two round shafts near the movable slot are fixedly connected to the ends away from the conveying roller. The two round shafts are connected to a large gear and a large gear. The large gear is located on the side of the small gears near the bottom inner wall of the frame. The large gear is located on the side away from the bottom inner wall of the frame. The large gear is fixedly installed on a transmission column on one side.

[0007] Furthermore, a servo motor is installed inside the frame. The output end of the servo motor passes through the movable slot two and is fixedly connected to the large gear one. A connecting block is provided at the output end of the servo motor. The output end of the servo motor and two round shafts near the side of the servo motor are rotatably installed inside the connecting block.

[0008] Furthermore, three sets of elongated grooves are symmetrically formed on the side wall of the extrusion cylinder, and two clamping plates are symmetrically slidably arranged on the extrusion cylinder. Rubber plates are fixedly connected to both sides of the clamping plates, and three connecting plates are fixedly connected to the inner wall of the clamping plates. The connecting plates are slidably arranged inside the elongated grooves, and a ring is slidably arranged inside the extrusion cylinder. The ring is fixedly installed between the three connecting plates, and a thread is formed on the inner wall of the ring. The threads inside the two rings are respectively connected to the threads at both ends of the screw.

[0009] The present invention has the following beneficial effects:

[0010] (1) In this invention, the aluminum profile passes between the conveying roller and the extrusion cylinder. Due to gravity, the aluminum profile is squeezed by the conveying roller. The conveying roller descends and the spring is compressed. Combined with the pressing action of the extrusion cylinder on the aluminum profile, the aluminum profile and the surface of the conveying roller can be tightly attached to each other, preventing the conveying roller from slipping and increasing the transmission efficiency of the device.

[0011] (2) In this invention, multiple gears rotate synchronously, the conveying roller rotates to transport the aluminum profile, and the extrusion cylinder rotates to push the aluminum profile again, which increases the practicality of the device.

[0012] (3) By rotating the handwheel, the clamping plates on both sides can be opened and closed. The rotating shaft slides inside the arc groove, which can clamp and transport aluminum profiles of various sizes. This ensures the stability of the aluminum profiles during transportation and avoids the situation of low processing efficiency caused by using a moving traction device to move back and forth and pull the aluminum profiles. It also avoids the situation of increasing production costs due to the addition of a traction head, which greatly improves the applicability of the device.

[0013] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 - Figure 7 As shown, the present invention is a traction device for automotive aluminum profiles, including a frame 1 and a mounting frame 2. Support legs 101 are fixedly connected to the four corners of the lower surface of the frame 1. Several conveying rollers 11 are rotatably installed inside the frame 1.

The conveying rollers 3 are located in the middle of the frame 1, and the extrusion cylinder 4 is located inside the mounting frame 2.

[0026] Two mounting holes 21 and two arc-shaped grooves 22 are symmetrically opened on the two side walls of the mounting bracket 2. A transmission column 23 is rotatably installed inside the mounting hole 21.

[0027] Both ends of the extrusion cylinder 4 are fixedly connected to a rotating shaft 41. The rotating shaft 41 is slidably disposed inside the arc groove 22. A belt 411 is connected to the end of the rotating shaft 41 located inside the mounting bracket 2. The end of the belt 411 away from the rotating shaft 41 is connected to the transmission column 23. The end of the rotating shaft 41 away from the extrusion cylinder 4 is fixedly connected to a mounting cylinder 412.

[0028] The screw 42 is rotatably mounted inside the extrusion cylinder 4, the rotating shaft 41 and the mounting cylinder 412. The threads at both ends of the screw 42 are in opposite directions, and a handwheel 421 is fixedly mounted on one end of the screw 42.

[0029] Two movable slots 12 are symmetrically opened in the middle of the two side walls of the frame 1. An arc-shaped block 13 is slidably arranged inside the movable slot 12. A spring 14 is fixedly installed between the lower surface of the arc-shaped block 13 and the bottom inner wall of the movable slot 12. A movable slot 2 15 is opened in the middle of one side wall of the frame 1. The movable slot 2 15 is located between the two movable slots 12.

[0030] Both ends of the conveyor roller 3 are fixedly connected to a round shaft 31. The round shaft 31 is slidably disposed inside the movable groove 12. The arc block 13 is located at the bottom of the round shaft 31. The ends of the two round shafts 31 near the movable groove 15 away from the conveyor roller 3 are fixedly connected to a small gear 32. The two small gears 32 are connected together by a large gear 1 33 and a large gear 2 36. The large gear 1 33 is located on the side of the small gear 32 near the bottom inner wall of the frame 1, and the large gear 2 36 is located on the side away from the bottom inner wall of the frame 1. The large gear 2 36 is fixedly installed on the transmission column 23 on one side.

[0031] The frame 1 is equipped with a servo motor 34. The output end of the servo motor 34 passes through the movable slot 15 and is fixedly connected to the large gear 33. The output end of the servo motor 34 is equipped with a connecting block 35. The output end of the servo motor 34 and two round shafts 31 near the side of the servo motor 34 are rotatably installed inside the connecting block 35.

[0032] Three sets of long grooves 43 are symmetrically opened on the side wall of the extrusion cylinder 4. Two clamping plates 44 are symmetrically slidably arranged on the extrusion cylinder 4. Rubber plates 441 are fixedly connected to both sides of the clamping plates 44. Three connecting plates 442 are fixedly connected to the inner wall of the clamping plates 44. The connecting plates 442 are slidably arranged inside the long grooves 43. A ring 45 is slidably arranged inside the extrusion cylinder 4. The ring 45 is fixedly installed between the three connecting plates 442. The inner wall of the ring 45 is threaded. The threads 451 inside the two rings 45 are respectively connected to the threads at both ends of the screw 42.

[0033] In use, the top of the conveyor roller 3 is at a higher horizontal position than the top of the conveyor roller 11. The aluminum profile is placed above the conveyor roller 11 and passes between the conveyor roller 3 and the extrusion cylinder 4. Due to gravity, the aluminum profile is squeezed against the conveyor roller 3, causing the conveyor roller 3 to descend. The spring 14 is compressed, and with the pressing action of the extrusion cylinder 4 on the aluminum profile, the aluminum profile can be tightly attached to the surface of the conveyor roller 3, preventing the conveyor roller 3 from slipping and increasing the transmission efficiency of the device.

[0034] The servo motor 34 is started, which drives the large gear 33 to rotate. The two small gears 32 are respectively meshed with the large gear 33 and the large gear 36. The rotation of the small gears 32 drives the conveyor roller 3 to rotate, which transports the aluminum profile. At the same time, the large gear 36 rotates, and through the transmission column 23 and the belt 411, the extrusion cylinder 4 rotates, which again pushes the aluminum profile, increasing the practicality of the device.

[0035] Furthermore, by setting the extrusion cylinder 4, the handwheel 421 can be rotated to control the screw 42 to rotate according to the different sizes of the aluminum profiles. Through the transmission connection between the threads at both ends of the screw 42 and the threads 451 on the two side rings 45, the clamping plates 44 on both sides can be controlled to move closer and further apart. In addition, with the rotating shaft 41 sliding inside the arc groove 22, aluminum profiles of various sizes can be clamped and transported, ensuring the stability of the aluminum profiles during transportation. This also avoids the situation of low processing efficiency caused by using a moving traction device to reciprocate and pull the aluminum profiles, and avoids the situation of increasing production costs due to adding a traction head, which greatly improves the applicability of the device.
