Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel plate technology, specifically a cold-rolled steel plate shearing machine with a feeding structure. Background Technology

[0002] Cold rolling is a process of rolling hot-rolled steel coils at room temperature below the recrystallization temperature. Cold-rolled steel sheets are steel sheets produced through the cold rolling process, also known as cold plates. The thickness of cold-rolled sheets is generally between 0.1 and 8 millimeters. Most factories produce cold-rolled steel sheets with a thickness of less than 4.5 millimeters. The thickness and width of cold-rolled sheets are determined by the equipment capabilities of each factory and market demand.

[0003] According to announcement number CN216729769U, a cold-rolled steel plate shearing machine with a feeding structure includes a main body, a feeding mechanism, an anti-slip pad, Velcro, a rotating shaft, a first rotating wheel, a drive belt, a second rotating wheel, a connecting shaft, a drive motor, fixing bolts, and a mounting block. The anti-slip pad is located below the main body, and Velcro is provided at both ends of the anti-slip pad. A rotating shaft is located on one side of the Velcro, and a first rotating wheel is mounted on one side of the rotating shaft. A drive belt is mounted on the surface of the first rotating wheel. Through the arrangement of the feeding mechanism, anti-slip pad, Velcro, rotating shaft, first rotating wheel, drive belt, second rotating wheel, connecting shaft, drive motor, fixing bolts, and mounting block, the device can perform autonomous feeding. The drive motor is mounted to the mounting block by tightening the fixing bolts. This mechanism eliminates manual feeding, reduces the workload of operators, lowers the dangers associated with manual feeding, and enhances its practicality.

[0004] The above-mentioned device installs the drive motor onto the mounting block by tightening the fixing bolts, eliminating the need for manual material feeding and enhancing its practicality. According to the instruction manual and attached drawings, for steel plates of different widths, the feeding position needs to be adjusted manually, which is time-consuming. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned device installs the drive motor on the mounting block by tightening the fixing bolts, which eliminates the manual feeding work and enhances its practicality. According to the specification and drawings, for steel plates of different widths, it is necessary to manually adjust the feeding position, which is time-consuming. Therefore, this utility model provides a cold-rolled steel plate shearing machine with a feeding structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cold-rolled steel plate shearing machine with a feeding structure, comprising a processing platform, support blocks symmetrically fixedly installed at the top of the processing platform, feeding roller shafts symmetrically rotatably connected at the middle of the two sets of support blocks, and a conveyor belt provided on the outer periphery of the feeding roller shafts, a shearing body provided at the top of the processing platform, and a shearing assembly provided at the top of the shearing body, a first through groove and a second through groove provided at the top of the processing platform, a sliding block one slidably connected inside the first through groove, a sliding block two slidably connected inside the second through groove, a connecting rack one fixedly installed through the first through groove of the sliding block one, a connecting rack two fixedly installed through the second through groove of the sliding block two, a rotating gear rotatably connected inside the processing platform, the rotating gear meshing with the connecting rack one and the connecting rack two, a connecting rod fixedly installed at the top of the sliding block one, and a guide plate fixedly installed at the top of the connecting rod.

[0007] As a further embodiment of this utility model: both the first through groove and the second through groove are provided with sliding grooves, and the sliding grooves are symmetrically provided inside the first through groove and the second through groove. Sliding blocks are symmetrically fixedly installed at both ends of the sliding block one and the sliding block two, and the sliding blocks are adapted to the sliding grooves.

[0008] As a further embodiment of this utility model: a groove is provided at one end of the guide plate, and a guide wheel that reduces the friction of feeding is rotatably connected inside the groove. The guide wheel is symmetrically rotatably connected inside the groove.

[0009] As a further improvement of this utility model, the processing platform is equipped with a drive assembly that drives the feeding roller shaft to rotate.

[0010] As a further improvement of this utility model, the outer periphery of the conveyor belt is provided with an anti-slip pad to increase transport stability.

[0011] As a further improvement of this utility model: a rotating motor is fixedly installed inside the processing platform, and the output shaft of the rotating motor is fixedly installed with a rotating gear.

[0012] As a further improvement of this utility model: drive discs are symmetrically fixedly installed at the rotation shafts of the two sets of rotating gears, and a connecting belt is provided in the middle of the two sets of drive discs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes gear and rack transmission and linkage to guide workpieces of different sizes. A rotating motor drives the rotating gears to rotate, and the synchronous transmission between the drive disc and the connecting belt ensures that the two sets of rotating gears operate in tandem. This causes the meshing connecting racks one and two to move in opposite directions, driving sliding blocks one and two to slide smoothly within the through groove. Furthermore, the connecting rod enables synchronous adjustment of the guide plate spacing. This structure utilizes the gear and rack transmission ratio to avoid errors from manual adjustment and can quickly adapt to the feeding requirements of workpieces of different widths. The guide wheels in the guide plate grooves reduce the workpiece conveying resistance through rolling friction, while the anti-slip pads on the outer periphery of the conveyor belt enhance the friction between the workpiece and the conveyor belt. The combination of these two features reduces the risk of workpiece scratches and prevents slippage and deviation during conveying, ensuring stable and smooth feeding. Attached Figure Description

[0024] The above scheme is adopted: the feeding roller shaft 5, the shearing body 3 and the shearing assembly 4 are all prior art referenced in the prior art documents, and are not described in detail in this application. The sliding block 10 and the sliding block 21 are made of ductile iron and form a clearance fit with the first through groove 8 and the second through groove 9. The bottom is inlaid with a PTFE self-lubricating strip. The connecting rack 12 and the connecting rack 23 are made of steel and mesh with the rotating gear 14. The rotating motor 15 is a 110ST-M04030 stepper motor and is connected to the gear shaft of the rotating gear 14 through an elastic coupling. The connecting rod 20 is made of aluminum alloy and is welded to the guide plate 21 (Q235 steel plate).

[0025] Reference Figures 1 to 5 Both the first through groove 8 and the second through groove 9 are provided with sliding grooves 18, and the sliding grooves 18 are symmetrically provided in the first through groove 8 and the second through groove 9. The sliding block 10 and the sliding block 2 11 are symmetrically fixed with sliders 19 at both ends, and the sliders 19 are adapted to the sliding grooves 18.

[0026] The above scheme is adopted: the material of the sliding groove 18 in the first through groove 8 and the second through groove 9 is bearing steel, the slider 19 is tin bronze, and it forms a clearance fit with the sliding groove 18. The inside is inlaid with graphite pillars to achieve lubrication-free operation. The slider 19 is fixed with the sliding block 10 and the sliding block 11 by internal hex screws.

[0029] Reference Figures 1 to 5 The processing platform 1 is equipped with a drive assembly 24 that drives the feeding roller shaft 5 to rotate, and the outer periphery of the conveyor belt 6 is equipped with an anti-slip pad 7 to increase transportation stability.

[0030] The above-mentioned solution is adopted: the drive assembly 24, the anti-slip mat 7 and the conveyor belt 6 are all prior art referenced in the prior art documents, and are not described in detail in this application. The drive assembly 24 includes a drive motor, a first wheel, a second wheel and a drive belt, etc.
