Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a steel plate trimming device. Background Technology

[0002] During the rolling process, steel plates often have defects such as cracks, oxide scale, burrs, and irregular curls at the edges. Cold-rolled steel plates may also have burrs or slight deformations at the edges. Edge trimming can precisely remove these defective areas, providing clean, flat, and dimensionally accurate edges. In addition, steel coils may experience "deviation" during uncoiling, causing dimensional fluctuations in the width direction. Edge trimming can precisely control the width tolerance of the final sheet material, meeting the stringent dimensional consistency requirements of downstream processing (such as stamping, bending, and welding).

[0003] In related technologies, the trimming mechanism is typically mounted above the steel plate, and the steel plate is then processed using mechanical cutting methods (e.g., cutting wheel, laser cutting). However, because the processing position is fixed, the orientation of the steel plate needs to be changed during the trimming process, which reduces the processing efficiency of the steel plate. In addition, the steel plate is prone to collision with the device during loading and unloading, which reduces the safety factor in the steel plate processing process. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a steel plate trimming device that eliminates the need to change the orientation of the steel plate, thereby improving the processing efficiency of the steel plate. Furthermore, during the loading and unloading process, some parts of this device can be lowered and moved away from the steel plate, thus improving the safety of the production process.

[0006] To achieve the above objectives, the first aspect of this utility model provides a steel plate trimming device, comprising: a processing table, a fixing mechanism, two sets of telescopic support mechanisms, a bidirectional drive mechanism, and a cutting mechanism, wherein the processing table is arranged vertically relative to the ground; the fixing mechanism is disposed on the processing table; the two sets of telescopic support mechanisms are symmetrically disposed on the processing table; the bidirectional drive mechanism is connected to the two sets of telescopic support mechanisms; the cutting mechanism includes a reversing component and a cutting component, wherein the reversing component is mounted on the movable seat of the bidirectional drive mechanism, and the cutting component is connected to the reversing component.

[0007] In addition, the steel plate trimming device proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the fixing mechanism includes two pads, a negative pressure suction assembly, and two suction cups. The two pads are symmetrically arranged on the processing table. The negative pressure suction assembly is installed at the bottom of the processing table, and the two suction cups are installed on the processing table and located between the two pads. The negative pressure suction assembly is connected to the two suction cups through an air pipe.

[0009] Specifically, the telescopic support mechanism includes two support rods, a hydraulic telescopic rod, and a limiting rod. Two grooves are symmetrically formed on the processing table. The two ends of the two support rods are pivotally connected to the processing table and the bidirectional drive mechanism, respectively. One end of the hydraulic telescopic rod is pivotally connected to one of the grooves, and the other end is pivotally connected to one of the support rods. The limiting rod is located on one side of the processing table and is positioned opposite one of the grooves, with one of the support rods abutting against the limiting rod.

[0010] Specifically, the bidirectional drive mechanism includes two first drive modules and a second drive module, wherein the two first drive modules are respectively connected to the corresponding telescopic support mechanism, and the second drive module is connected to the movable seat of the two first drive modules.

[0011] Specifically, the reversing assembly includes a first base plate, a second base plate, a positioning pin, and a spring. The first base plate is mounted on the movable seat of the second drive module, and the second base plate is rotatably connected to the first base plate. The positioning pin passes through the second base plate, and the spring is sleeved on the outside of the positioning pin and embedded inside the second base plate. Two positioning slots are symmetrically formed on the first base plate, and one end of the positioning pin is inserted into the inside of one of the positioning slots.

[0012] Specifically, a laser emitter is mounted on the second substrate.

[0013] Compared with the prior art, the present invention has the following advantages: The steel plate trimming device of the present invention utilizes the bidirectional drive mechanism and the reversing component in the cutting mechanism to adjust the traveling direction of the cutting component, thereby eliminating the need to change the direction of the steel plate and improving the processing efficiency of the steel plate. In addition, during the loading and unloading process, the telescopic support mechanism can reduce the height, so that the cutting mechanism is away from the steel plate, thereby avoiding the collision between the steel plate and the device, and thus improving the safety of the production process.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The steel plate trimming device of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the steel plate trimming device of this utility model embodiment may include: a processing table 1, a fixing mechanism 2, two sets of telescopic support mechanisms 3, a bidirectional drive mechanism 4, and a cutting mechanism 5.

[0023] The processing table 1 is arranged vertically relative to the ground.

[0024] It should be noted that the processing table 1 described in this embodiment is provided with support legs at the four corners of its bottom. The support legs can reduce the contact area between the processing table 1 and the ground, increase the pressure between the two, and increase the stability of the device during use.

[0025] The fixing mechanism 2 is set on the processing table 1, and two sets of telescopic support mechanisms 3 are symmetrically arranged on the processing table 1. The bidirectional drive mechanism 4 is connected to the two sets of telescopic support mechanisms 3. The cutting mechanism 5 includes a reversing component 51 and a cutting component 52. The reversing component 51 is installed on the moving seat of the bidirectional drive mechanism 4, and the cutting component 52 is connected to the reversing component 51.

[0026] It should be noted that the cutting component 52 described in this embodiment can be an abrasive wheel cutter or a laser cutter. Its specific structure and working principle have been disclosed in the prior art, so they will not be described in detail here.

[0027] In the above embodiment, a controller is also installed on the processing table 1. The fixing mechanism 2, the telescopic support mechanism 3, the bidirectional drive mechanism 4 and the cutting mechanism 5 are respectively connected to the controller. The controller can control the processing steps of the device according to the preset operating data.

[0028] Specifically, in the initial state, the bidirectional drive mechanism 4 is in contact with the processing table 1, and the cutting mechanism 5 is away from the processing table 1, thereby avoiding collision between the steel plate and the processing table 1 during the feeding process.

[0029] Since steel plates are generally quite heavy, during the loading and unloading process, relevant technicians use external hoisting equipment to move the steel plates and place them on this device. They then mark the positions on the steel plates that need to be cut and adjust the position of the steel plates on this device.

[0030] The relevant technicians send an operation signal to the fixing mechanism 2 through the controller. The fixing mechanism 2 can fix the steel plate at the bottom of the steel plate, thereby ensuring the accuracy of the edge cutting.

[0031] The controller sends a running signal to the telescopic support mechanism 3, which moves to be perpendicular to the processing table 1. Then, the bidirectional drive mechanism 4 is activated, so that the cutting mechanism 5 is placed above the steel plate and the cutting part 52 is aligned with the marked position.

[0032] The controller sends a signal to the cutting component 52. Under the action of the bidirectional drive mechanism 4, the cutting component 52 completes the cutting of one side of the steel plate. Then, the cutting component 52 is moved to the other parallel side of the steel plate, and the above steps are repeated to complete the cutting of the other parallel side of the steel plate.

[0033] Subsequently, the relevant technicians used the reversing component 51 to rotate the cutting component 52 by 90°. After the direction of travel of the cutting component 52 was adjusted, there was no need to change the direction of the steel plate. The above steps were repeated to complete the processing of the remaining edges of the steel plate, thereby improving the processing efficiency of the steel plate.

[0034] After the steel plate is trimmed, the cutting mechanism 5 resets and the telescopic support mechanism 3 operates, causing the bidirectional drive mechanism 4 to fit against the processing table 1. At the same time, the cutting mechanism 5 moves away from the steel plate, thereby avoiding collision between the steel plate and the device, thus improving safety during the production process. Relevant technicians can use external hoisting devices to transfer the steel plate.

[0035] In one embodiment of this utility model, such as Figure 2 As shown, the fixing mechanism 2 includes two pad rods 21, a negative pressure suction assembly 22, and two suction cups 23.

[0036] Two pads 21 are symmetrically arranged on the processing table 1, the negative pressure suction assembly 22 is installed at the bottom of the processing table 1, and two suction cups 23 are installed on the processing table 1 and located between the two pads 21. The negative pressure suction assembly 22 is connected to the two suction cups 23 through an air pipe.

[0037] It should be noted that the top of the suction cup 23 described in this embodiment is higher than the upper surface of the pad rod 21. When the steel plate is placed on the processing table 1, the suction cup 23 first contacts the lower surface of the steel plate, thereby ensuring that it can provide force to the steel plate.

[0038] Furthermore, the specific structure and working principle of the negative pressure extraction component 22 described in this embodiment have been disclosed in the prior art, so they will not be described in detail here.

[0039] Specifically, during the operation of the fixing mechanism 2, the suction cup 23 contacts the lower surface of the steel plate. Under the action of the negative pressure suction component 22, a negative pressure is generated inside the suction cup 23, thereby generating a downward pulling force on the steel plate. The pad rod 21 can reduce the contact area between the steel plate and the processing table 1, thereby ensuring the stability of the steel plate during the trimming process.

[0040] In one embodiment of this utility model, such as Figure 1 As shown, the telescopic support mechanism 3 includes two support rods 32, a hydraulic telescopic rod 33, and a limiting rod 34.

[0041] The processing table 1 has two symmetrical slots 31. The two ends of the two support rods 32 are pivotally connected to the processing table 1 and the bidirectional drive mechanism 4, respectively. One end of the hydraulic telescopic rod 33 is pivotally connected to a slot 31, and the other end of the hydraulic telescopic rod 33 is pivotally connected to a support rod 32. The limiting rod 34 is set on one side of the processing table 1 and is arranged opposite to a slot 31. A support rod 32 abuts against the limiting rod 34.

[0042] Specifically, during the operation of the telescopic support mechanism 3, the telescopic support mechanism 3 and the bidirectional drive mechanism 4 are similar to a parallelogram structure. The two hydraulic telescopic rods 33 are controlled by a hydraulic cylinder and can operate synchronously. The hydraulic telescopic rod 33 pushes or pulls a support rod 32 to tilt, thereby changing the height of the bidirectional drive mechanism 4 and moving the cutting mechanism 5 away from or closer to the steel plate.

[0043] When the hydraulic telescopic rod 33 pushes a support rod 32 to rotate, the limit rod 34 can block the support rod 32. After receiving the resistance signal, the hydraulic telescopic rod 33 can stop running to ensure that the support rod 32 is perpendicular to the processing table 1.

[0044] In one embodiment of this utility model, such as Figure 1 As shown, the bidirectional drive mechanism 4 includes two first drive modules 41 and a second drive module 42.

[0045] Among them, the two first drive modules 41 are respectively connected to the corresponding telescopic support mechanism 3, and the second drive module 42 is connected to the movable seat of the two first drive modules 41.

[0046] It should be noted that the first drive module 41 and the second drive module 42 described in this embodiment can both be electric slide module structures in the prior art. Their specific structures and working principles have been disclosed in the prior art, so they will not be described in detail here.

[0047] In one embodiment of this utility model, such as Figure 3 As shown, the commutation assembly 51 includes a first substrate 511, a second substrate 512, a positioning pin 513, and a spring 514.

[0048] The first substrate 511 is mounted on the movable seat of the second drive module 42. The second substrate 512 is rotatably connected to the first substrate 511. The positioning pin 513 passes through the second substrate 512. The spring 514 is sleeved on the outside of the positioning pin 513 and embedded in the inside of the second substrate 512. Two positioning grooves 515 are symmetrically opened on the first substrate 511. One end of the positioning pin 513 is inserted into the inside of one of the positioning grooves 515.

[0049] Specifically, when the angle of the cutting component 52 is changed using the reversing component 51, the relevant technicians can pull the positioning pin 513, the spring 514 is compressed, and one end of the positioning pin 513 disengages from a positioning groove 515. Then, the second base plate 512 is rotated and the positioning pin 513 is released. When the positioning pin 513 meets another positioning groove 515, under the action of the spring 514, one end of the positioning pin 513 can be automatically inserted into the interior of the other positioning groove 515. At this time, it indicates that the cutting component 52 has rotated 90°, thereby ensuring the processing accuracy of the cutting component 52.

[0050] In one embodiment of this utility model, such as Figure 2 As shown, a laser emitter 61 is mounted on the second substrate 512.

[0051] It is understandable that the laser emitter 61 and the cutting component 52 are directly opposite each other. When adjusting the cutting position of the steel plate, the laser emitter 61 can play an auxiliary role to help the steel plate adjust quickly.

[0052] In summary, the steel plate trimming device of this utility model utilizes the bidirectional drive mechanism and the reversing component in the cutting mechanism to adjust the travel direction of the cutting component, thereby eliminating the need to change the direction of the steel plate and improving the processing efficiency of the steel plate. In addition, during the loading and unloading process, the telescopic support mechanism can reduce its height, allowing the cutting mechanism to move away from the steel plate, thereby avoiding collision between the steel plate and the device and improving the safety of the production process.
