Description

Technical Field

[0001] This utility model belongs to the field of steel coil shearing technology, specifically, it relates to a cold-rolled steel coil shearing device. 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 according to the equipment capabilities of each factory and market demand.

[0003] Chinese utility model patent CN221833571U discloses a cold-rolled steel plate shearing machine with a feeding structure. The cold-rolled steel plate is placed on a conveying device, which automatically feeds the plate while an upper conveyor fixing device prevents it from shifting during transport, thus reducing shearing errors. After shearing, the rear conveyor fixing device and the conveying device also prevent the sheared cold-rolled steel plate from uncoiling, ensuring the flatness of the sheet and facilitating collection and placement. A shearing working space is provided between the two conveying devices and below the shearing device to prevent damage to the conveyor belt during shearing. The laser shearer in the shearing device can be adjusted laterally using a rodless cylinder. Combined with the conveying device, this allows for better shearing of the cold-rolled steel plate.

[0004] Although the shearing machine can transport materials and reduce errors, the steel plate may shift or tilt during the transport process, which will make the cut of the steel plate uneven. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cold-rolled steel coil shearing device that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A cold-rolled steel coil shearing device includes a mounting bracket with a hollow interior. Supporting vertical plates are fixedly connected to both sides of the upper end of the mounting bracket. Cutting shears are slidably connected to the outer walls of the supporting vertical plates. The cutting shears move downwards to shear the steel plate. Mounting vertical plates are detachably connected to the side of the mounting bracket closest to the supporting vertical plates. A conveying roller is rotatably connected between the two mounting vertical plates. A protrusion is provided at the upper end of the mounting bracket, and multiple through slots are provided on the protrusion. A bottom rotating roller is rotatably connected inside each through slot. Clamping wheels are rotatably connected to both sides of the protrusion.

[0008] Preferably, the outer wall of the clamping wheel is provided with a tapered outer wall, and the upper end of the mounting bracket is fixedly connected with multiple mounting bosses. Each mounting boss has a bearing detachably connected inside, and the bottom of each clamping wheel is fixedly connected with a sliding rod, which is slidably connected to the inner ring of the bearing.

[0009] Preferably, mounting brackets are fixedly connected to both sides of the interior, and a U-shaped frame is detachably connected to the bottom of multiple sliding rods. The two vertical sides of the U-shaped frame are attached to the outer wall of the mounting brackets. An electric telescopic rod is detachably connected to the bottom of the interior, and the telescopic end of the electric telescopic rod is detachably connected to the horizontal side of the U-shaped frame. The extension and retraction of the electric telescopic rod can cause the U-shaped frame to move upward or downward. The clamping wheel can be moved upward or downward by the sliding rod.

[0010] Preferably, drive shafts are fixedly connected to the outer walls of both sides of the conveyor roller, and vertical mounting plates extend through the two drive shafts. A first sprocket is detachably connected to the outer wall of the sliding track at one end of the drive shaft. A drive motor is detachably connected to the bottom inner side of the mounting bracket, and a second sprocket is detachably connected to the rotating end of the drive motor. A first chain is sleeved between the outer wall of the second sprocket and the outer wall of the first sprocket.

[0011] Preferably, the outer walls of the two vertical plates are detachably connected to sliding rails, the cutting scissors are slidably connected to the outer walls of the two sliding rails, the two ends of the cutting scissors are rotatably connected to rotating rods, the upper end of the mounting bracket is provided with movable grooves on both sides, the two rotating rods pass through the movable grooves, the outer walls of the opposite sides of the two vertical plates are rotatably connected to rotating disks, the rotating rod on each side is rotatably connected to the outer wall of the adjacent rotating disk near the outer edge, and a connecting shaft passing through the two vertical plates is fixedly connected between the two rotating disks. The rotation of the connecting shaft causes the cutting scissors to move up and down reciprocatingly.

[0012] Preferably, a fourth sprocket is detachably connected to the outer wall of the connecting shaft, and a third sprocket is detachably connected to the outer wall of the rotating end of the drive motor. A second chain is sleeved on the outer walls of the third and fourth sprockets. By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0013] 1. Place the steel plate under the conveyor roller. The rotation of the conveyor roller causes the steel plate to be transported towards the cutting shears. The cutting shears move downward to complete the cutting of the steel plate. The clamping wheels on both sides clamp the outer wall of the steel plate, thereby preventing lateral movement during the steel plate transport process.

[0014] 2. The U-shaped frame can be moved up or down by extending and shortening the electric telescopic rod. In turn, the clamping wheels can be moved up or down by the sliding rod. The conical outer wall of the clamping wheels can make the clamping distance between two opposite clamping wheels smaller when the clamping wheels move down and larger when the clamping wheels move up, thus allowing adjustment according to the width of the steel plate.

[0015] 3. The drive motor rotates, which drives the second sprocket to rotate, thereby enabling the first chain to drive the first sprocket to rotate, which in turn enables the conveyor roller to rotate and transport the steel plate.

[0016] 4. When the drive motor rotates and drives the conveyor roller to rotate, the connecting shaft and the rotating rods on both sides are driven to rotate by the third sprocket in conjunction with the second chain and the fourth sprocket. The rotation and swing of the rotating rods on both sides causes the cutting shears to move up and down reciprocatingly. This allows the cutting shears to move downwards to cut the steel plate when it is being conveyed. On the one hand, this reduces production and usage costs, and on the other hand, it can quickly cut multiple steel plates of the same size. The length of the steel plate being cut can be changed by changing the gear ratio of the third sprocket and the fourth sprocket.

The telescopic rod 205 is detachably connected to the transverse side of the U-shaped frame 204 by extending and shortening the electric telescopic rod 205. In this embodiment, the U-shaped frame 204 can be moved upward or downward by extending and shortening the electric telescopic rod 205, and the clamping wheel 200 can be moved upward or downward by sliding rod 203. The tapered outer wall 201 provided on the outer wall of the clamping wheel 200 can make the clamping distance between two opposite clamping wheels 200 smaller when the clamping wheel 200 moves downward and larger when the clamping wheel 200 moves upward, so as to adjust according to the width of the steel plate.

[0030] like Figure 1 as well as Figure 4 As shown, this is a schematic diagram of the power assembly structure in this embodiment. The outer walls of both sides of the conveyor roller 301 are fixedly connected to the drive shaft 302. The drive shaft 302 extends through the vertical mounting plates 105 on both sides.

In conjunction with the rotation and swaying of the rotating rods 309 on both sides, the cutting shears 300 make up-and-down reciprocating motion, so that the cutting shears 300 can move downward to cut the steel plate when conveying the steel plate. On the one hand, it can reduce the production and use cost, and on the other hand, it can quickly cut multiple steel plates of the same size. The length of the steel plate to be cut can be changed by changing the gear ratio of the third sprocket 308 and the fourth sprocket 312.
