Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular relates to a cutting device with adjustable cutting angle for steel structure processing. Background Technology

[0002] With the rapid progress of modern industry and construction, steel structures have been widely used in various large-scale infrastructure construction, high-rise and super high-rise buildings, heavy machinery manufacturing and other fields due to their excellent mechanical properties, outstanding designability and good economy. In the steel structure processing, cutting is a basic and key link, and its cutting effect directly affects the dimensional accuracy, connection performance and overall stability of steel structure components.

[0003] However, in the use of existing steel structure processing cutting devices with adjustable cutting angles, the position of the steel plate is prone to shift, which affects the cutting angle and causes the cutting angle of the steel plate to be inconsistent with the actual angle, thus reducing the processing efficiency of the steel plate. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device with an adjustable cutting angle for steel structure processing. By setting up a clamping mechanism, the problem of the steel plate's position easily shifting, which affects the change in the cutting angle, causing the cutting angle of the steel plate to be inconsistent with the actual angle, thus reducing the processing efficiency of the steel plate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a cutting device with adjustable cutting angle for steel structure processing, including a base, on which a clamping mechanism and a cutting mechanism are provided;

[0007] The clamping mechanism includes a rectangular box fixedly connected to the top of the base. A motor is fixedly connected to the bottom of the base. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The top of the rotating shaft passes through the base and extends outward. The rotating shaft is rotatably connected to the base. A fixing rod is fixedly connected to the outer wall of the rotating shaft. Two hinged rods are hinged on the fixing rod. Two slide rails are fixedly connected between the front inner wall and the rear inner wall of the rectangular box. Two rectangular slots are formed on the top of the rectangular box. The cutting mechanism includes a bracket fixedly connected to the top of the base. A hydraulic cylinder is fixedly connected to the bottom of the bracket.

[0008] Furthermore, a support frame is fixedly connected to the bottom of the base, and two sliders are slidably connected to the inner walls of the two slide rails. Several sliders are slidably connected to the two rectangular grooves respectively.

[0009] Furthermore, two clamping plates are fixedly connected to the top of several of the sliders, a rectangular groove is provided on the top of the rectangular box, and a cylindrical rod is fixedly connected to the bottom of each of the two clamping plates. Both cylindrical rods are slidably connected to the rectangular groove.

[0010] Furthermore, the two hinge rods are respectively hinged to the two cylindrical rods, and buffer pads are fixedly connected to the sides of the two clamping plates that are close to each other.

[0011] Furthermore, a movable plate is fixedly connected to the bottom of the hydraulic cylinder, and two sliding rods are fixedly connected between the top of the base and the bottom of the bracket. Both sliding rods pass through the movable plate and are slidably connected to the movable plate.

[0012] Furthermore, a cylindrical rod two is rotatably connected to the bottom of the movable plate, a cutter bracket is fixedly connected to the bottom of the cylindrical rod two, a cutter is fixedly connected to the cutter bracket, and a rotating shaft two passes through the movable plate, the rotating shaft two being rotatably connected to the movable plate.

[0013] Furthermore, gears are fixedly connected to the outer wall of the second rotating shaft and the outer wall of the second cylindrical rod, and the two gears mesh with each other. A ratchet is fixedly connected to the outer wall of the second rotating shaft, a fixing block is fixedly connected to the top of the moving plate, and a telescopic rod is fixedly connected to the outer wall of the fixing block.

[0014] Furthermore, a limiting block is fixedly connected to the side of the telescopic rod away from the fixed block, the limiting block is adapted to the ratchet, a spring is sleeved on the outer wall of the telescopic rod, the right side of the spring is fixedly connected to the limiting block, the left side of the spring is fixedly connected to the fixed block, and a handle is fixedly connected to the outer wall of the second rotating shaft.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a clamping mechanism and starting the motor, the motor drives the fixed rod to rotate clockwise through the rotating shaft. At this time, the fixed rod will pull the two hinge rods to move. The two hinge rods will drive the two clamping plates to move closer to each other through the cylindrical rod. At this time, the clamping plates will move in the two slide rails through the two sliders at the bottom. Under the action of the two sliders, the clamping plates will move in parallel, thereby fixing the steel plate. With the action of the buffer pad, the steel plate is prevented from being worn, so that it maintains a fixed position during the cutting process and prevents displacement or shaking due to cutting force and other factors, ensuring the accuracy and stability of cutting and improving cutting precision.

[0017] 2. By setting up a cutting mechanism, when adjusting the angle of the cutter, pulling the limiting block compresses the telescopic rod and spring. At this time, the spring generates elastic force, causing the limiting block to move away from the ratchet gear. Then, turning the handle drives the rotating shaft two to rotate. The rotating shaft two then drives the cylindrical rod two to rotate through two gears. The cylindrical rod two then drives the cutter on the cutter holder to rotate, thereby adjusting the cutting position of the cutter. Subsequently, the limiting block is released. Under the action of the spring force, the limiting block is locked into the ratchet gear, thereby limiting the rotation of the slider through the ratchet gear. In turn, the two clamping plates limit the rotation of the cylindrical rod two, thus fixing the cutting angle of the cutter. This ensures that the cutting tool and the steel structure workpiece maintain the correct angular relationship, thereby ensuring the flatness and perpendicularity of the cut surface, improving cutting quality and accuracy, and increasing processing efficiency.

[0030] A specific application of this embodiment is as follows: In use, the steel plate is placed on the rectangular box 211, and then the motor 212 is started. The motor 212 drives the fixed rod 214 to rotate clockwise through the first rotating shaft 213. At this time, the fixed rod 214 pulls the two hinge rods 215 to move. The two hinge rods 215 drive the two clamping plates 219 to move closer to each other through the first cylindrical rod 2111. At this time, the clamping plates 219 move in the two slide rails 216 through the two sliders 218 at the bottom. Under the action of the two sliders 218, the clamping plates 219 move in parallel, thereby fixing the steel plate. Under the action of the buffer pad 2112, the steel plate is prevented from being worn. Then, the hydraulic cylinder 312 is started. The output shaft of the hydraulic cylinder 312 pushes the moving plate 313 to slide on the two slide rods 314. At this time, the moving plate 313 drives the cutter 317 on the cutter bracket 316 to move through the second cylindrical rod 315. This allows for the cutting of steel plates. When the angle of the cutter 317 needs to be adjusted, the limiting block 3113 is pulled to compress the telescopic rod 3112 and the spring 3114. At this time, the spring 3114 generates elastic force, causing the limiting block 3113 to move away from the position of the ratchet 3110. Then, the handle 3115 is turned to drive the rotating shaft 318 to rotate. At this time, the rotating shaft 318 drives the cylindrical rod 315 to rotate through the two gears 319. The cylindrical rod 315 drives the cutter 317 on the cutter bracket 316 to rotate, thereby adjusting the cutting position of the cutter 317. Then, the limiting block 3113 is released. Under the action of the spring 3114, the limiting block 3113 is locked into the ratchet 3110, thereby restricting the rotation of the slider 218 through the ratchet 3110, and restricting the rotation of the cylindrical rod 315 through the two clamping plates 219, thereby fixing the cutting angle of the cutter 317.
