Description
Technical Field
[0001] This utility model relates to the technical field of steel component sawing devices, and in particular to a steel component sawing device. Background Technology
[0002] The main function of steel component sawing equipment is to cut and separate various types of steel components (such as steel beams, steel columns, steel plates, etc.) according to predetermined dimensions and shapes. It is widely used in the steel processing stage in many industries such as construction, machinery manufacturing, bridge construction, and shipbuilding to meet the specific size and shape requirements of steel components for different engineering projects.
[0003] Currently, during sawing, workers typically pull the saw blade with one hand while pressing down on the steel component with the other. However, the saw blade rotates at high speed during the sawing process, generating enormous kinetic energy. If it comes into contact with the human body, it can cause serious cutting injuries. Furthermore, sawing steel components generates a large amount of flying debris. This debris is irregular in shape and travels at a certain speed. If this debris splashes onto the operator, it can easily cause injury. Utility Model Content

[0006] The aforementioned components achieve the following effects: The steel component is placed on the base. The output of the first motor is connected to the saw blade via a reducer and coupling. Starting the first motor drives the saw blade to rotate. The output of the third motor is connected to the screw via a reducer and coupling. The third motor is a Y2-160m1-8 model. Starting the third motor drives the screw to rotate, which in turn causes the slider to move the saw blade, cutting the steel component. After the steel component is placed, sliding the two protective covers covers the cutting area, blocking debris and preventing the generation of large amounts of flying debris during sawing. This flying debris is irregular in shape and travels at a certain speed, and flying debris can easily injure operators if it hits them.
[0007] Preferably, the base is provided with a sliding groove, and two sliding strips are slidably connected in the sliding groove, and the sliding strips are fixedly connected to the protective cover.
[0008] The effect achieved by the above components is that the slider slides within the groove, making the movement of the protective cover more stable.
[0009] Preferably, a rack is fixedly connected to the protective cover, and a gear is meshed on both racks. The gear is rotatably connected to the base via a bearing, and a second motor is fixedly connected to the base. The gear is driven to rotate by the second motor.
[0010] The effect achieved by the above components is as follows: the output end of the second motor is connected to the gear through a reducer and a coupling. The model of the second motor is 17HS4401. Starting the second motor can drive the gear to rotate, so that the two racks drive the two protective covers to slide synchronously in opposite directions, making the operation of opening and closing the protective covers more convenient.
[0011] Preferably, the base is provided with a limiting structure, which mainly consists of two fixing plates, both of which are fixedly connected to the base. The base has two sliding grooves, in which sliding plates are slidably connected.
[0012] The effect achieved by the above components is: placing the steel component on the base, sliding the sliding plate, so that the fixed plate and the sliding plate clamp and limit the steel component.
[0013] Preferably, a round rod is fixedly connected to the sliding plate, the round rod is slidably inserted into the base, and a connecting rod is fixedly connected to both round rods.
[0014] The effect achieved by the above components is that the operator can push the connecting rod to drive the two round rods to slide synchronously, making the limit operation more convenient.
[0015] Preferably, a threaded rod is threaded into the connecting rod, and one end of the threaded rod is rotatably connected to the base via a bearing.
[0016] The effect achieved by the above components is that rotating the threaded rod can drive the connecting rod to move.
[0017] Preferably, the protective cover has clearance grooves on both sides, and limit blocks are slidably connected in the clearance grooves.
[0018] The effect achieved by the above components is that after the two protective covers are closed, the clearance groove allows longer steel components to pass through, and the two sliding limit blocks can further limit the longer steel components.
[0019] Preferably, a sliding rod is fixedly connected to the limiting block, the sliding rod is slidably inserted into the protective cover, a spring is sleeved on the sliding rod, one end of the spring is fixedly connected to the inner wall of the relief groove, and the other end of the spring is fixedly connected to the limiting block.
[0020] The effect achieved by the above components is that when the limiting block contacts the steel component, the spring is in a contracted state, so the spring's rebound force acts on the limiting block, making the limiting more stable.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a protective structure, the steel component is placed on the base. The output end of the first motor is connected to the saw blade through a reducer and a coupling. Starting the first motor drives the saw blade to rotate. The output end of the third motor is connected to the screw through a reducer and a coupling. The model of the third motor is Y2-160m1-8. Starting the third motor can drive the screw to rotate, which in turn causes the slider to drive the saw blade to move and cut the steel component. After the steel component is placed, sliding two protective covers cover the cutting position, which can block the debris and avoid the generation of a large amount of flying debris when sawing the steel component. These flying debris are irregular in shape and have a certain speed. The flying debris can easily cause injury to the operator if it splashes onto the operator. Attached Figure Description

[0028] Reference Figures 2 to 4A protective structure 4 is provided on the base 1. The protective structure 4 mainly consists of two protective covers 41, both of which are slidably connected to the base 1. A gantry frame 47 is fixedly connected to the base 1, and a slider 48 is slidably connected to the gantry frame 47. The slider 48 is rotatably connected to the saw blade 2 through a bearing. A first motor 3 is fixedly connected to the slider 48. A rectangular groove 411 is provided on the base 1. A screw 49 is rotatably connected to the gantry frame 47 through a bearing. The screw 49 is threadedly connected to the slider 48. A third motor 41 is fixedly connected to the gantry frame 47. 0. The screw 49 is driven to rotate by the third motor 410, placing the steel component on the base 1. The output end of the first motor 3 is connected to the saw blade 2 through a reducer and coupling. Starting the first motor 3 drives the saw blade 2 to rotate. The output end of the third motor 410 is connected to the screw 49 through a reducer and coupling. The model of the third motor 410 is Y2-160m1-8. Starting the third motor 410 drives the screw 49 to rotate, which in turn causes the slider 48 to move the saw blade 2 to cut the steel component. After the steel component is placed, the two sliding guards... The cover 41 allows two protective covers to enclose the cutting position, blocking debris and preventing the generation of large amounts of flying debris during the sawing of steel components. This flying debris is irregular in shape and travels at a certain speed, and can easily injure operators if it splashes onto them. The base 1 has a groove 42, in which two sliding strips 43 are slidably connected. The sliding strips 43 are fixedly connected to the protective covers 41, and their limited sliding within the groove 42 makes the movement of the protective covers 41 more stable. The protective covers 41 are fixedly connected to... There is a rack 44, and two racks 44 are connected to a gear 45. The gear 45 is rotatably connected to the base 1 through a bearing. A second motor 46 is fixedly connected to the base 1. The gear 45 is driven to rotate by the second motor 46. The output end of the second motor 46 is connected to the gear 45 through a reducer and a coupling. The model of the second motor 46 is 17HS4401. Starting the second motor 46 can drive the gear 45 to rotate, so that the two racks 44 drive the two protective covers 41 to slide synchronously in opposite directions, making the operation of opening and closing the protective covers 41 more convenient.
[0029] Reference Figure 3 and Figure 4A limiting structure 5 is provided on the base 1. The limiting structure 5 mainly consists of two fixed plates 51, both of which are fixedly connected to the base 1. Two sliding grooves 52 are provided on the base 1, and sliding plates 53 are slidably connected in the sliding grooves 52. When a steel component is placed on the base 1, the sliding plates 53 are slidably connected, so that the fixed plates 51 and the sliding plates 53 clamp and limit the steel component. A round rod 54 is fixedly connected to the sliding plate 53 and is slidably inserted into the base 1. A connecting rod 55 is fixedly connected to both round rods 54. The operator can push the connecting rod 55 to drive the two round rods 54 to slide synchronously, making the limiting operation more convenient. A threaded rod 56 is threaded into the connecting rod 55. One end of the threaded rod 56 is rotatably connected to the base 1 through a bearing. The threaded rod 56 can drive the connecting rod 55 to move. The protective cover 41 has relief grooves 57 on both sides. Limiting blocks 58 are slidably connected in the relief grooves 57. After the two protective covers 41 are closed, the relief grooves 57 can allow longer steel components to pass through, and the two sliding limiting blocks 58 can further limit the longer steel components. A sliding rod 59 is fixedly connected to the limiting block 58. The sliding rod 59 is slidably inserted into the protective cover 41. A spring 510 is sleeved on the sliding rod 59. One end of the spring 510 is fixedly connected to the inner wall of the relief groove 57, and the other end of the spring 510 is fixedly connected to the limiting block 58. When the limiting block 58 contacts the steel component, the spring 510 is in a contracted state. Therefore, the rebound force of the spring 510 acts on the limiting block 58, making the limiting more stable.
[0030] Working principle: The steel component is placed on the base 1. The output end of the first motor 3 is connected to the saw blade 2 through a reducer and coupling. Starting the first motor 3 drives the saw blade 2 to rotate. The output end of the third motor 410 is connected to the screw 49 through a reducer and coupling. The model of the third motor 410 is Y2-160m1-8. Starting the third motor 410 drives the screw 49 to rotate, which in turn causes the slider 48 to move the saw blade 2 to cut the steel component. After the steel component is placed, the two protective covers 41 slide to cover the cutting position, which can block the debris and avoid the generation of a large amount of flying debris during the sawing of the steel component. These flying debris are irregular in shape and have a certain speed. If the flying debris splashes onto the operator, it can easily cause injury. The slider 43 slides in the groove 42 to limit the movement of the protective cover 41, making the movement of the protective cover 41 more stable. The output end of the second motor 46... The second motor 46, model 17HS4401, is connected to the gear 45 via a reducer and coupling. Starting the second motor 46 drives the gear 45 to rotate, causing the two racks 44 to drive the two protective covers 41 to slide synchronously in opposite directions, making the opening and closing of the protective covers 41 more convenient. The steel component is placed on the base 1, and the sliding plate 53 is slid, so that the fixed plate 51 and the sliding plate 53 clamp and limit the steel component. The operator can push the connecting rod 55 to drive the two round rods 54 to slide synchronously, making the limiting operation more convenient. Rotating the threaded rod 56 can drive the connecting rod 55 to move. After the two protective covers 41 are closed, the clearance groove 57 allows longer steel components to pass through, and the two sliding limit blocks 58 can further limit the longer steel components. When the limit block 58 contacts the steel component, the spring 510 is in a contracted state, so the rebound force of the spring 510 acts on the limit block 58, making the limiting more stable.
