Description

Technical Field

[0001] This utility model relates to the field of slitting technology for rolled plates, specifically a slitting device for rolled plates. Background Technology

[0002] Coiled steel is a common steel product, usually referring to steel plates that are much wider than thicker and delivered in coils. It is widely used in machinery manufacturing, construction, automobiles, ships, pressure vessels and other fields.

[0003] For example, a slitting device for rolled plates, with announcement number "CN211192326U", has four sets of hollow columns fixed to the lower surface of the first support plate by bolts. Four sets of first support columns are inserted into the four sets of hollow columns, and rollers are rotatably connected to the first support columns. Springs and damping shock absorbers are fixed between the lower surface of the inner cavity of the hollow columns and the upper surface of the first support columns by bolts. The damping shock absorbers pass through the springs. When the cutting blade cuts the rolled plate downwards, the four sets of rollers first contact the rolled plate. The piston rod of the first cylinder then moves downwards, causing the first support columns to enter the hollow columns. Under the reaction force of the springs and damping shock absorbers, the rollers firmly press the rolled plate down, effectively preventing the rolled plate from rolling over during cutting and greatly improving the accuracy of cutting. However, during cutting, the cutting blade and motor need to move together. When the motor moves, the motor wires are prone to bending. Also, the fixing mechanism cannot be adjusted, limiting its ability to cut rolled plates of a fixed width. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the above-mentioned devices, which require the cutting blade and motor to move together during cutting, and the motor wires are prone to bending when the motor moves. In addition, the fixing mechanism of the above-mentioned devices cannot be adjusted and can only cut rolls of fixed width, which has limitations. Therefore, a roll slitting device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A slitting device for rolled plates is designed, including a base plate, an adjustment mechanism inside the base plate, a first bending plate and a second bending plate fixedly connected to the upper end of the base plate, a feeding mechanism below the first bending plate, and the outer wall of the base plate being threadedly connected to a motor by bolts. The output shaft of the motor is fixedly connected to a rotating roller.

[0007] Preferably, the rotating shafts at both ends of the roller are rotatably connected to the base plate via bearings, and a laser cutter is installed on the outer wall of the second curved plate.

[0008] Preferably, the adjusting mechanism includes a multi-stage electric telescopic rod and a sliding rod. The output end of the multi-stage electric telescopic rod is fixedly connected to a first vertical plate. Both ends of the sliding rod are fixedly connected to a base plate. The outer wall of the sliding rod is slidably connected to the first vertical plate and the second vertical plate. A spring is sleeved on the outer wall of the sliding rod.

[0009] Preferably, the two ends of the spring are fixedly connected to the second vertical plate and the bottom plate respectively, and the outer wall of the multi-stage electric telescopic rod is fixedly connected to the protrusion of the bottom plate.

[0010] Preferably, the feeding mechanism includes an electric telescopic rod, the output end of which is fixedly connected to a bracket, the inner wall of which is rotatably connected to the pressure roller via a bearing, and a sliding sleeve is fixedly connected to the upper end of the outer wall of the bracket.

[0011] Preferably, the outer wall of the electric telescopic rod is fixedly connected to the second curved plate, and the inner wall of the sliding sleeve is slidably connected to the protrusion of the second curved plate.

[0012] The beneficial effects of the roll plate longitudinal shearing device proposed in this utility model are as follows:

[0013] Through the cooperation of the feeding mechanism and the rotating roller, the output shaft of the motor rotates and drives the rotating roller to rotate, which in turn drives the coil plate to move to the right. The coil plate moves to the right and is cut at the lower end of the laser cutter. The coil plate is limited by the first vertical plate and the second vertical plate to move in a straight line. The bottom plate is processed with a cutting groove at the lower end of the laser cutter to ensure thorough cutting. The coil plate is cut by the feeding mechanism. The movement of the coil plate relative to the movement of the cutting blade can prevent the motor from breaking the line.

[0014] By adjusting the mechanism and the base plate, the output end of the multi-stage electric telescopic rod extends and drives the two first vertical plates to move. The movement of the two first vertical plates drives the roll plate to move, and the movement of the roll plate drives the second vertical plate to move. The distance the second vertical plate moves is observed according to the scale lines on the base plate. The distance the second vertical plate moves is the width of the roll plate that is cut. After reaching the appropriate distance, the multi-stage electric telescopic rod stops. The movement of the second vertical plate compresses the spring. The spring force makes the second vertical plate fit against the roll plate. The worker uses bolts to pass through the threaded holes on the protrusions of the second vertical plate and press it against the base plate to achieve self-locking of the second vertical plate. By adjusting the positions of the first and second vertical plates, roll plates of different widths can be limited, thereby enabling the processing of roll plates of different widths and reducing limitations.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] See attached document Figure 1-6 :

[0024] In this embodiment, a roll plate slitting device includes a base plate 1 with scale lines machined on it. An adjustment mechanism 2 is provided inside the base plate 1. A first bending plate 3 and a second bending plate 7 are fixedly connected to the upper end of the base plate 1. A feeding mechanism 4 is provided below the first bending plate 3. The outer wall of the base plate 1 is threadedly connected to a motor 6 by bolts.

[0025] The output shaft of motor 6 is fixedly connected to a rotating roller 5. The rotation of the output shaft of motor 6 drives the rotating roller 5 to rotate. The rotating roller 5 is made of rubber to increase friction. The rotating shafts at both ends of the rotating roller 5 are rotatably connected to the base plate 1 through bearings. A laser cutter 8 is installed on the outer wall of the second curved plate 7.

[0026] See attached document Figure 1-3 And 5-6:

[0027] The adjustment mechanism 2 includes a multi-stage electric telescopic rod 201 and a slide rod 204. The output end of the multi-stage electric telescopic rod 201 is fixedly connected to a first vertical plate 202. The extension and retraction of the output end of the multi-stage electric telescopic rod 201 drives the first vertical plate 202 to move. Both ends of the slide rod 204 are fixedly connected to the base plate 1. The outer wall of the slide rod 204 is slidably connected to the first vertical plate 202 and the second vertical plate 203.

[0028] The first vertical plate 202 and the second vertical plate 203 limit the linear movement. The outer wall of the slide rod 204 is fitted with a spring 205. The two ends of the spring 205 are fixedly connected to the second vertical plate 203 and the base plate 1 respectively. The second vertical plate 203 moves to compress the spring 205. The outer wall of the multi-stage electric telescopic rod 201 is fixedly connected to the protrusion of the base plate 1.

[0029] See attached document Figure 1 , 4 And 6:

[0030] The feeding mechanism 4 includes an electric telescopic rod 401. The output end of the electric telescopic rod 401 is fixedly connected to a bracket 402. The extension and retraction of the output end of the electric telescopic rod 401 drives the bracket 402 to move. The inner wall of the bracket 402 is rotatably connected to the pressure roller 404 through a bearing. The movement of the bracket 402 drives the pressure roller 404 to move.

[0031] A sliding sleeve 403 is fixedly connected to the upper end of the outer wall of the bracket 402. The movement of the bracket 402 causes the sliding sleeve 403 to move. The outer wall of the electric telescopic rod 401 is fixedly connected to the second curved plate 7. The inner wall of the sliding sleeve 403 is slidably connected to the protrusion of the second curved plate 7. The sliding sleeve 403 is limited by the second curved plate 7 to move linearly.

[0032] Working principle:

[0033] When longitudinally shearing the rolled sheet.

[0034] Work process:

[0035] The operator passes the roll plate through the middle of the two pairs of first vertical plates 202 and second vertical plates 203 to the left side of the laser cutter 8, so that one side of the roll plate is in contact with the inner outer wall of the second vertical plate 203 (the inner outer wall of the second vertical plate 203 is on the same horizontal line as the cutting line of the laser cutter 8). Then the operator simultaneously starts the two multi-stage electric telescopic rods 201. The two multi-stage electric telescopic rods 201 are connected to the same PLC controller and start synchronously through programming control.

[0036] The output end of the multi-stage electric telescopic rod 201 extends and drives the two first vertical plates 202 to move. The movement of the two first vertical plates 202 drives the roll plate to move. The movement of the roll plate drives the second vertical plate 203 to move. The distance the second vertical plate 203 moves is observed according to the scale line on the base plate 1. The distance the second vertical plate 203 moves is the width of the roll plate being cut. After reaching the appropriate distance, the multi-stage electric telescopic rod 201 stops. (The multi-stage electric telescopic rod 201 is a multi-stage electric telescopic rod with self-locking). The movement of the second vertical plate 203 compresses the spring 205 (the spring 205 is equipped with a spring damper). The elastic force of the spring 205 makes the second vertical plate 203 fit with the roll plate. The operator uses bolts to pass through the threaded holes on the protrusions of the second vertical plate 203 and press it against the base plate 1 to achieve the self-locking of the second vertical plate 203.

[0037] Afterwards, the staff started the electric telescopic rod 401 through the PLC controller. The output end of the electric telescopic rod 401 extended and drove the bracket 402 to move downward. The downward movement of the bracket 402 drove the pressure roller 404 and the sliding sleeve 403 to move downward. The sliding sleeve 403 was limited by the protrusion of the second bending plate 7 and moved linearly. When the pressure roller 404 pressed the rolled plate against the rotating roller 5, the electric telescopic rod 401 stopped. The electric telescopic rod 401 is a self-locking electric telescopic rod to ensure that the position of the pressure roller 404 is fixed.

[0038] Then, the motor 6 and laser cutter 8 are started. The output shaft of the motor 6 rotates, driving the roller 5 to rotate, which in turn drives the roll plate to move to the right. The roll plate moves to the right and is cut at the lower end of the laser cutter 8. The roll plate is limited by the first vertical plate 203 and the second vertical plate 203 to move linearly. The base plate 1 has a cutting groove processed at the lower end of the laser cutter 8 to ensure thorough cutting, thus realizing the cutting of the roll plate. When the cutting is completed, a part cannot be conveyed to the right by the roller 5. The operator can manually pull the roll plate to pull it out. The dust in the base plate 1 can be cleaned by a combination of air gun and manual cleaning.
