Description

Technical Field

[0001] This utility model relates to the field of steel plate cutting technology, and more specifically, to a cutting device for steel plate processing. Background Technology

[0002] Steel plates are flat steel materials made by pouring molten steel, cooling and pressing. There are many types of steel plates, which are used in various fields. In actual use, the size of the steel plate may not meet the requirements. Therefore, the steel plate is cut and processed by a cutting machine. The cutting device is the key equipment for realizing the blanking and forming of steel plates. Its cutting accuracy, stability and safety directly affect the subsequent processing quality and production efficiency. Traditional devices fix and limit the steel plate by clamping it from both sides. During the cutting process, the steel plate is easily moved by the movement of the cutting disc, resulting in uneven cuts. The steel plate may also bounce at the cutting position due to its thinness, affecting the cutting effect. At the same time, the cutting disc is subjected to uneven force, and the high-speed rotating cutting disc has a large exposed area, resulting in a wide range of iron filings flying during the cutting process, which is inconvenient to clean and may cause injury to the operator. Therefore, a cutting device for steel plate processing is proposed. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cutting device for steel plate processing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for steel plate processing, including a support frame, a plurality of conveying rollers arranged in the middle of the support frame for supporting and conveying the steel plate, a control panel fixedly connected to one side of the support frame, a collection box arranged at the bottom of the support frame for collecting the cutting debris, and a support frame fixedly connected to the top of the support frame at a position corresponding to the collection box; The support frame has a limiting groove in the middle, and a limiting slider is slidably arranged in the middle of the limiting groove. A threaded rod and a first stabilizing rod are arranged in the middle of the limiting groove. One end of the threaded rod is connected to a first motor. A clamping and limiting mechanism is arranged on one side of the top of the support frame. The first motor is started to control the threaded rod to drive the limiting slider to slide inside the limiting groove, which can adjust the stability of the limiting slider. The stability of the limiting slider movement is improved by the first stabilizing rod. The limiting clamping mechanism can limit the conveyed steel plate and clamp the steel plate during cutting. An electric push rod is fixedly connected to the top of the limiting slider. The output end of the electric push rod extends to the bottom of the limiting slider and is fixedly connected to a drive box. Activating the electric push rod controls the drive box to move up and down, which in turn controls the cutting disc to move downward for cutting. A cooling fan, a controller, and a second motor are located in the middle of the drive box. The output end of the second motor extends to one side of the drive box and is fixedly connected to the cutting disc. Activating the second motor controls the cutting disc to rotate, which can cut the steel plate. The cooling fan dissipates heat from the second motor. A protective plate is fixedly connected to one side of the drive box. A pressing and fixing mechanism is located at the bottom of the drive box. The protective plate can limit and block the debris generated during cutting, causing the debris to fall into the middle of the collection box. The pressing and fixing mechanism can press and fix the steel plate at the cutting part during cutting without affecting the cutting movement, thus improving the usage effect.

[0005] Preferably, one end of the conveying roller is connected to a synchronous pulley, and a synchronous belt is sleeved between multiple synchronous pulleys. One end of one of the conveying rollers is connected to a conveying motor. The collection box is located directly below the cutting disc. Starting the conveying motor controls multiple conveying rollers to rotate synchronously, which facilitates the conveying of steel plates from one side to the other.

[0006] Preferably, the cross-sectional shape of the limiting slider is set to "H" shape, and the threaded rod and the first stabilizing rod both pass through the middle of the limiting slider. The threaded rod is threadedly connected to the limiting slider. The stability of the limiting slider movement is improved by the cooperation of the limiting slider and the limiting groove, and the stability of the limiting slider movement is further improved by the first stabilizing rod.

[0007] Preferably, a fixed frame is symmetrically fixedly connected to both sides of the limiting slider, and a second stabilizing rod is symmetrically fixedly connected to both sides of the drive box. The second stabilizing rod passes through the middle of the fixed frame, and the stability of the drive box moving up and down can be improved by the fixed frame sliding inside the second stabilizing rod.

[0008] Preferably, the protective plate is fitted over the middle of the cutting disc, and arc-shaped baffles are symmetrically arranged at both ends of the protective plate. The cutting disc and the conveying roller are staggered. The protective plate blocks and guides the debris generated during cutting, thereby improving the collection effect.

[0009] Preferably, the extrusion fixing mechanism includes fixed plates fixed to both sides of the drive box, a pressure plate is provided at the bottom of the drive box, a third stabilizing rod is fixedly connected to the top of the pressure plate around its perimeter, the top of the third stabilizing rod passes through the fixed plate and is fixedly connected to a limiting plate, a spring is sleeved in the middle of the third stabilizing rod, and a ball bearing is embedded in the bottom of the pressure plate. When the drive box moves downward, the ball bearing at the bottom of the pressure plate will fit against the bottom steel plate. Continuing to move the drive box can compress the spring, increasing the extrusion effect of the pressure plate on the bottom steel plate. The stability of the pressure plate's up and down movement is improved by the third stabilizing rod, and the ball bearing can reduce the frictional resistance and improve the extrusion effect when the cutting disc moves and drives the pressure plate to move.

[0010] Preferably, the clamping and limiting mechanism includes auxiliary uprights fixed to both sides of the top of the support bed frame. Two stabilizing crossbars are fixedly connected between the two auxiliary uprights. A limiting clamp is sleeved in the middle of the stabilizing crossbar. The limiting clamp is sleeved on three of the conveying rollers. A screw is inserted into the bottom end of the limiting clamp. One end of the screw passes through the wall of the support bed frame and is fixedly connected to a servo motor. The threads at both ends of the screw are symmetrical. Activating the servo motor controls the screw to drive the limiting clamp to move. The distance between the two limiting clamps can be adjusted, thereby facilitating the limiting of both sides of the conveyed steel plate. During cutting, controlling the limiting clamp to clamp both sides of the steel plate can improve the fixing strength.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model firstly uses a compression and fixing mechanism to control the bottom ball bearings of the pressure plate to adhere to and compress the bottom steel plate when the cutting disc moves downward. This compresses and fixes the steel plate during cutting. When the cutting disc moves, the ball bearings adhere to the steel plate, reducing friction and improving the smoothness of the cutting movement. Furthermore, the combination of clamping and limiting mechanisms prevents the steel plate from moving, improving the fixed cutting effect. The steel plate is also limited during transport, and the protective plate shields the cutting debris to prevent it from flying and injuring people. It is also convenient to collect and clean it centrally through a collection box. 2. This utility model also controls the threaded rod to drive the limiting slider to slide inside the limiting groove by starting the first motor, which can adjust the stability of the limiting slider, thereby driving the cutting disc to move horizontally. The cutting disc can be moved up and down sequentially by starting the electric push rod. The stability of lifting is improved by the cooperation of the second stabilizing rod and the fixed frame. The stability of the limiting slider movement is improved by the cooperation of the first stabilizing rod. The cooling fan can cool down the second motor. The stability of the pressure plate is improved by the third stabilizing rod. In summary, through the interaction of the above-mentioned functions, it is convenient to squeeze and fix the steel plate during cutting without affecting the use of mobile cutting. At the same time, it can shield the debris generated during cutting, avoid flying debris that may injure people, and facilitate collection and cleaning. Attached Figure Description

During cutting, the servo motor 27 is started to control the screw 26 to drive the limit clamping plate 25 to clamp and fix the steel plate on both sides. The first motor 10 is started to control the limit slider 7 to move the cutting disc 16 to the top of one end of the steel plate. Then the electric push rod 11 is started to control the cutting disc 16 to move downwards. At the same time, the second motor 15 is started to control the cutting disc 16 to rotate until the pressure plate 20 presses and fixes the bottom steel plate, achieving double fixation and improving the fixing effect on the steel plate. Then the cutting disc 16 cuts the steel plate. During the cutting process, the ball bearing 23 adheres to the surface of the steel plate and does not affect the normal movement of the cutting disc 16. By starting the first motor 10, the cutting disc 16 is moved in sequence, which can drive the pressure plate 20 to move on the top of the steel plate, thereby improving the stability of the steel plate cutting and improving the cutting effect.
