Description

Technical Field

[0001] The invention relates to the technical field of aluminum material processing, in particular to a traction device for an aluminum profile production line. Background Art

[0002] Aluminum profiles are long strips. During the production process, they are mainly produced by extrusion molding. Since they are produced by high-temperature melting and then molding, during the extrusion and transportation on the production line, at present, when producing flat aluminum profiles, operators are required to manually pull the flat aluminum profiles out of the production device, which not only causes high labor intensity for operators, but also has great safety hazards in manual operation. After the aluminum profiles are extruded, auxiliary equipment at the rear end is required to pull the formed aluminum profiles out. The traditional tractor uses a vehicle-mounted hydraulic station to drive the equipment. The hydraulic equipment has high cost and high failure rate. When the vehicle-mounted hydraulic station drives the clamping mechanism to move, the aluminum profiles are often deformed and waste is generated. Therefore, it is necessary to propose an effective solution to solve the above problems.

[0003] The Chinese patent (Announcement No.: CN 209439226 U, Announcement Date: 2019.09.27) discloses a traction device for an aluminum extrusion production line, including a frame, a screw transmission mechanism, a traction device, and a displacement sensor; the screw transmission mechanism includes a screw, a screw nut, and a first motor; the traction device includes a drive assembly and a clamping assembly; the drive assembly includes a base plate, a base, a second motor, a worm, and a gear; the clamping assembly includes a first connecting rod, a second connecting rod, a third connecting rod, and a clamping seat; after the second motor is started and drives the worm to rotate, the worm drives the gears to rotate in opposite directions, and then the gears rotate and drive the closing or opening of the two third connecting rods through the first connecting rod and the second connecting rod, so that the two clamping seats can clamp or release the aluminum profile. The device has a complex structure and uses multiple drive devices, which increases the production cost and is not convenient for promotion and implementation. Summary of the invention

[0004] The object of the present invention is to provide a traction device for an aluminum profile production line to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A traction device for an aluminum profile production line includes a workbench and a sliding frame. A horizontal hydraulic rod is fixedly installed at one end of the workbench, and a horizontal double-sided toothed plate is fixedly connected at one end of the hydraulic rod. The sliding frame is slidably placed on the workbench, and the double-sided toothed plate is placed below the sliding frame. Two gears are symmetrically arranged on both sides of the double-sided toothed plate on the lower surface of the sliding frame, and the two gears are respectively meshed with the teeth on the two side walls of the double-sided toothed plate. Two rotating shafts are arranged on the upper surface of the sliding frame, and the two rotating shafts are coaxially fixedly connected with the gears. The rotating shaft is fixedly connected to one end of the rotating rod, and a clamping block is fixedly connected to the other end of the rotating rod, and the hydraulic rod is connected to a controller. When the hydraulic rod contracts, the double-sided toothed plate is pulled to move to the right end, so that the gear rotates, and the rotation of the gear drives the rotating shaft to rotate so that the rotating rod rotates inward, and the two clamping blocks move inward to clamp the aluminum profile. At this time, the gear cannot rotate, so that the double-sided toothed plate pulls the sliding frame to move, thereby completing the traction of the aluminum profile. After being pulled to the specified position, the hydraulic rod stops contracting and extends, the double-sided toothed plate moves to the left, thereby pushing the gear to rotate in the opposite direction, the rotating shaft rotates in the opposite direction to open the rotating rod, and the clamp moves outward to release the aluminum profile. The backs of the two rotating rods touch each other, the gear cannot rotate, and the double-sided toothed plate pushes the sliding frame back to its original position.

[0007] As a further solution of the present invention: the rotating rod is an L-shaped structure bent outward, so as to facilitate the clamping of the aluminum profile.

[0008] As a further solution of the present invention: a rubber layer is arranged on the inner side of the clamping block, and the arrangement of the rubber layer increases the friction force of the clamping block, increases the stability of the clamping block, and makes the traction more reliable.

[0009] As a further solution of the present invention: a limit rod is fixedly provided on the upper surface of the sliding frame at the side of the rotating shaft, and the limit rod has the function of limiting the rotation of the rotating rod, thereby avoiding the rotating rod from rotating at an excessively large angle and improving work efficiency.

[0010] As a further solution of the present invention: sliding wheels are arranged at the four corners of the bottom of the sliding frame, and the arrangement of the sliding wheels enables the sliding frame to slide more smoothly.

[0011] As a further solution of the present invention: a groove is provided on the upper surface of the workbench, and the sliding wheel is nested in the lower groove. The sliding wheel can rotate in the groove, and the setting of the groove makes the sliding of the sliding frame more stable.

[0012] As a further solution of the present invention: two groups of vertical nesting grooves are opened inside the clamping block, and sliding blocks are symmetrically placed inside the nesting grooves, and springs are arranged outside the sliding blocks. Clamps are fixedly connected to the corresponding sliding blocks, and the clamps are plate-like structures with open ends, so as to facilitate the clamping of aluminum profiles. A vertical rotating rod is rotatably arranged inside the nesting groove, and the rotating rod slides through the spring and the sliding block.

[0013] As a further solution of the present invention: threads are symmetrically provided at both ends of the rotating rod and connected with nuts, a clamping block extends from the top of the rotating rod and is coaxially connected with a rotating cap, and the rotating cap can be turned to rotate the rotating rod inside the nesting groove, and a spring is nested on the rotating rod between the clamping plate and the nut. The rotating cap is turned to rotate the rotating rod, and the nut moves inside and outside the rotating rod, thereby adjusting the compression of the spring, thereby controlling the clamping degree of the clamping plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the hydraulic rod contracts, pulling the double-sided toothed plate to move to the right end, thereby causing the gear to rotate, and the rotation of the gear drives the rotation shaft to rotate so that the rotating rod rotates inward, and the two clamping blocks move inward to clamp the aluminum profile. At this time, the gear cannot rotate, so that the double-sided toothed plate pulls the sliding frame to move, thereby completing the traction of the aluminum profile. After traction to the specified position, the hydraulic rod stops contracting and extends, the double-sided toothed plate moves to the left, thereby pushing the gear to rotate in the opposite direction, the rotating shaft rotates in the opposite direction to open the rotating rod, and the clamping block moves outward, thereby releasing the aluminum profile, and the backs of the two rotating rods contact, the gear cannot rotate, and the double-sided toothed plate pushes the sliding frame back to the original position. Using one hydraulic rod to complete the drive simplifies the device, reduces the production and manufacturing cost, and has good synchronization. The advantages of the present invention are simple structure, low manufacturing cost, good synchronization, convenient operation, strong applicability, and easy promotion and implementation.

[0019] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention is now described with reference to the accompanying drawings.

[0020] Example 1

[0021] See also Figure 1-2A traction device for an aluminum profile production line includes a workbench 1 and a sliding frame 4. A horizontal hydraulic rod 2 is fixedly installed at one end of the workbench 1, and a horizontal double-sided toothed plate 3 is fixedly connected at one end of the hydraulic rod 2. The sliding frame 4 is slidably placed on the workbench 1, and the double-sided toothed plate 3 is placed below the sliding frame 4. Two gears 10 are symmetrically arranged on both sides of the double-sided toothed plate 3 on the lower surface of the sliding frame 4, and the two gears 10 are respectively engaged with the teeth on the two side walls of the double-sided toothed plate 3. Two rotating shafts 5 are rotatably arranged on the upper surface of the sliding frame 4, and the two rotating shafts 5 are coaxially fixedly connected with the gear 10. The rotating shaft 5 is fixedly connected to one end of the rotating rod 6, and the other end of the rotating rod 6 is fixedly connected to a clamping block 7, and the hydraulic rod 2 is connected to a controller. The hydraulic rod 2 contracts, pulling the double-sided toothed plate 3 to move to the right end, thereby rotating the gear 10, and the rotation of the gear 10 drives the rotating shaft 5 to rotate, so that the rotating rod 6 rotates inward, and the two clamping blocks 7 move inward, thereby clamping the aluminum profile. At this time, the gear 10 cannot rotate, so the double-sided toothed plate 3 pulls the sliding frame 4 to move, thereby completing the traction of the aluminum profile. After traction to the specified position, the hydraulic rod 2 stops contracting and extends, and the double-sided toothed plate 3 moves to the left, thereby pushing the gear 10 to rotate in the opposite direction, and the rotating shaft 5 rotates in the opposite direction to open the rotating rod 6, and the clamping block 7 moves outward, thereby releasing the aluminum profile, and the backs of the two rotating rods 6 are in contact, the gear 10 cannot rotate, and the double-sided toothed plate 3 pushes the sliding frame 4 back to the original position.

[0022] The rotating rod 6 is an L-shaped structure bent outward, so as to facilitate the clamping of the aluminum profile. A rubber layer 12 is provided on the inner side of the clamping block 7. The setting of the rubber layer 12 increases the friction of the clamping block 7, increases the stability of the clamping of the clamping block 7, and makes the traction more reliable. A limit rod 11 is fixedly provided on the side of the rotating shaft 5 on the upper surface of the sliding frame 4. The limit rod 11 has the function of limiting the rotation of the rotating rod 6, thereby avoiding the rotating angle of the rotating rod 6 being too large and improving the work efficiency. Sliding wheels 9 are provided at the four corners of the bottom of the sliding frame 4. The setting of the sliding wheels 9 makes the sliding frame 4 slide more smoothly. A groove 8 is provided on the upper surface of the workbench 1. The sliding wheel 9 is nested in the lower groove 8. The sliding wheel 9 can rotate in the groove 8. The setting of the groove 8 makes the sliding of the sliding frame 4 more stable.

[0023] The working principle of the present invention is as follows: the hydraulic rod 2 contracts, pulling the double-sided toothed plate 3 to move to the right end, thereby rotating the gear 10, and the rotation of the gear 10 drives the rotating shaft 5 to rotate, thereby rotating the rotating rod 6 inward, and the two clamping blocks 7 move inward to clamp the aluminum profile. At this time, the gear 10 cannot rotate, so that the double-sided toothed plate 3 pulls the sliding frame 4 to move, thereby completing the traction of the aluminum profile. After traction to the specified position, the hydraulic rod 2 stops contracting and extends, the double-sided toothed plate 3 moves to the left, thereby pushing the gear 10 to rotate in the opposite direction, the rotating shaft 5 rotates in the opposite direction to open the rotating rod 6, and the clamping block 7 moves outward, thereby releasing the aluminum profile, and the backs of the two rotating rods 6 contact the limit rod 11, the gear 10 cannot rotate, and the double-sided toothed plate 3 pushes the sliding frame 4 back to the original position.

A vertical rotating rod 15 is rotatably provided inside the nesting groove 14, and the rotating rod 15 slides through the spring 16 and the sliding block 18. The two ends of the rotating rod 15 are symmetrically provided with threads and connected with nuts 19. The top of the rotating rod 15 extends out of the clamping block 7 and is coaxially connected with a rotating cap 13. The rotating cap 13 can be screwed to make the rotating rod 15 rotate inside the nesting groove 14. A spring 16 is nested on the rotating rod 15 between the clamping plate 17 and the nut 19. The rotating cap 13 is screwed to rotate the rotating rod 15 , so that the nut 19 moves inward and outward on the rotating rod 15 , thereby adjusting the compression amount of the spring 16 , thereby controlling the clamping degree of the clamping plate 17 .
