Description

Technical Field

[0001] This utility model relates to the technical field of multi-roller straightening machine devices, specifically an automatic adjustment device for a semi-circular arc stop block used in a large multi-roller straightening machine. Background Technology

[0002] Chinese patent document CN218283526U discloses a discharge device for a multi-roller round steel straightener, including a support base. A support frame is welded to the rear side of the top of the support base. Rollers are movably connected to the front of the support frame via bearings. A drive assembly is mounted on the surface of the support base. A lifting assembly is mounted at the bottom of the inner cavity of the support base. A lifting plate is mounted on the surface of the lifting assembly. A buffer assembly is mounted at the front end of the lifting plate. The drive assembly includes a sprocket, which is fixedly sleeved on the rear end of the roller. A chain is drivenly connected to the surface of the sprocket. This invention solves the problem of current discharge mechanisms for multi-roller round steel straighteners on the market, which can only convey steel bars to the material frame along the conveying direction and cannot place the straightened steel bars to one side. Such discharge mechanisms occupy a relatively large area, increasing the production cost for enterprises.

[0003] However, in the above-mentioned solutions and existing technologies, when large multi-roller straighteners are in operation, the steel from multiple sets of feeding platforms is shredded and then needs to be manually rotated or the baffles added or removed to adjust the material blocking device according to different specifications. This operation is cumbersome and time-consuming and needs to be improved and optimized.

[0004] Therefore, this utility model proposes an automatic adjustment device for a semi-circular arc stop block for a large multi-roller straightener to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By installing a baffle limit plate and coordinating with the hydraulic cylinder to start, the transmission rod moves a specified distance, which in turn moves the moving plate. During the process, the guide column moves in the guide groove, which in turn drives the guide plate to rotate, thus realizing the rotation of the angle adjustment arm. After the semi-circular stop block follows the rotation of the angle adjustment arm, the overlap distance between the feeding rod and the round steel can be controlled. This enables the automatic adjustment of the stop according to the steel specifications before feeding multiple sets of feeding platforms in a large multi-roller straightener. The operation is simple and time-saving. Attached Figure Description

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-6 The present invention provides the following two preferred embodiments:

[0023] Example 1: An automatic adjustment device for a semi-circular arc stop block in a large multi-roller straightener, comprising: a loading platform 1, a fixed base 2, and an adjustment assembly; a hydraulic cylinder 3 is fixedly mounted on the upper end of the fixed base 2, the output end of the hydraulic cylinder 3 is fixedly connected to a transmission rod 4, the loading platform 1 is equidistantly arranged, the transmission rod 4 is located below the loading platform 1, and a sleeve 5 is fixedly mounted on the side wall of the loading platform 1; characterized in that: the adjustment assembly includes a semi-circular arc stop block 7, a moving plate 9, and a support base 13. An angle adjusting arm 6 is rotatably installed inside the sleeve 5. A semi-circular arc stop block 7 is fixedly installed at the upper end of the angle adjusting arm 6. The semi-circular arc stop block 7 is engaged with the loading platform 1. A guide plate 8 is fixedly installed at the lower end of the angle adjusting arm 6. A movable plate 9 is fixedly installed at equal intervals on the side wall of the transmission rod 4. A guide groove 10 is opened on the movable plate 9. A guide post 11 is fixedly installed at the bottom end of the guide plate 8. A limit plate 12 is fixedly installed at the end of the guide post 11. The guide post 11 is movably engaged in the guide groove 10.

[0024] In use, the hydraulic cylinder 3 is activated, causing the transmission rod 4 to move a specified distance, which in turn causes the moving plate 9 to move. During this process, the guide column 11 moves within the guide groove 10, thereby driving the guide plate 8 to rotate and achieving the rotation of the angle adjustment arm 6. After the semi-circular stop block 7 follows the rotation of the angle adjustment arm 6, the overlap distance between the feeding rod and the round steel can be controlled, thus realizing the automatic adjustment of the stop according to the steel specifications before feeding multiple sets of feeding platforms 1 of the large multi-roller straightener. The operation is simple and time-saving.

[0025] Example 2: Based on Example 1, the support base 13 is symmetrically arranged on both sides of the transmission rod 4. A collar 14 is fixedly installed at the end of the support base 13, and the collar 14 is sleeved with the transmission rod 4. A fixing plate 15 is fixedly installed on the side wall of the support base 13. Trapezoidal mounting grooves 16 are equidistantly opened on the side wall of the fixing plate 15. A trapezoidal mounting block 17 is fixedly installed at the bottom of the baffle 18, and the trapezoidal mounting block 17 is inserted into the trapezoidal mounting groove 16. A clip is fixedly installed on the periphery of the transmission rod 4. Plate 19, clamping plate 19 and baffle 18 are engaged; a protrusion 20 is fixedly provided on the side wall of the baffle 18, and a plug 21 is movably inserted into the side wall of the protrusion 20. A pull ring is fixedly provided at the end of the plug 21. A limit block 22 is fixedly sleeved on the plug 21. The limit block 22 is engaged with the fixed plate 15. A spring 23 is sleeved on the plug 21. The two ends of the spring 23 are engaged with the protrusion 20 and the limit block 22 respectively. An insertion hole 24 is opened on the bottom wall of the trapezoidal mounting groove 16. The plug 21 is inserted into the insertion hole 24.

[0026] During use, the transmission rod 4 moves within the collar 14, ensuring its stability. Simultaneously, the rotation position of the semi-circular stop block 7 is adjusted according to the specifications of the steel to be fed onto the multiple feeding platforms 1 of the large multi-roller straightener. After the trapezoidal mounting block 17 is inserted into the corresponding trapezoidal mounting groove 16, the compressed spring 23 resets, pushing the limit block 22 to move, causing the insertion post 21 to engage with the insertion hole 24, thus fixing the position of the baffle 18. During the movement of the transmission rod 4, the clamping plate 19 engages with the baffle 18, limiting its movement and controlling the distance the hydraulic cylinder 3 pushes the transmission rod 4, thereby ensuring the accuracy of the rotation of the semi-circular stop block 7.
