Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cutting, and more specifically, to a steel plate cutting device. Background Art

[0002] Steel plate is a flat steel material made by pouring molten steel and pressing it after cooling. Steel plates are divided into hot-rolled and cold-rolled according to the rolling process. With the development of science and technology and industry, higher requirements are put forward for materials, such as higher strength, resistance to high temperature, high pressure and other special physical and chemical properties. Cutting devices are needed to cut steel plates during the production and disposal process of steel plates.

[0003] Manually use a handheld gas cutting head to move on the steel plate. First, preheat the edge of the steel plate, and then wait for the edge to burn red before using the high-pressure wind handheld gas cutting head to move on the steel plate. Keep the height of the cutting nozzle about 5mm from the steel plate. If the distance between the cutting nozzle and the steel plate is smaller, the cutting nozzle may be blocked, causing internal tempering and thus damaging the cutting nozzle. The residue splashes out and hurts the construction workers. If the distance between the cutting nozzle and the steel plate becomes larger, the cutting effect is poor.

[0004] However, in the existing situation, the operator needs to hold the gas cutting gun, which is prone to fatigue due to the long squatting time, and there is a situation that the operator cannot grasp the distance well.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0026] Example:

[0027] A steel plate cutting device, such as Figure 1-Figure 7 As shown, it includes a gas cutting gun 1 and a base 2 fixedly arranged on the gas cutting gun 1, a rotating block 3 is rotatably arranged on the base 2, and the rotating direction of the rotating block 3 is perpendicular to the length of the gas cutting gun 1, and a supporting foot 4 is arranged on the rotating block 3 and rotates along the length of the gas cutting gun 1, so that the effect of unfolding the supporting foot 4 is achieved by rotating in different directions, and the supporting foot 4 provides a support point for the user, reducing the weight that the user needs to bear during the holding process, and can effectively control the distance between the gas cutting gun 1 and the workpiece, thereby reducing the occurrence of errors caused by poor distance control, and at the same time, a roller 5 is rotatably arranged on the end of the supporting foot 4 away from the rotating block 3, and the roller 5 reduces the friction resistance during movement, thereby further improving the user's convenience in operation.

[0028] like Figure 2-Figure 4As shown, the supporting foot 4 includes a supporting body 6 rotatably connected to the rotating block 3 and an extension part 7 slidably arranged on the supporting body 6, and the roller 5 is rotatably arranged on the extension part 7, so as to control the sliding distance of the extension part 7, thereby realizing the control of the height distance between the gas cutting gun 1 and the workbench where the workpiece is placed, and then the height can be adjusted according to the different thicknesses of the workpieces to ensure that the distance between the workpiece and the gas cutting gun 1 is fixed, and an abutting block 8 for abutting the extension part 7 is slidably arranged on the supporting body 6, and an elastic element 9 is arranged between the abutting block 8 and the supporting body 6 to push the abutting block 8 to abut the extension part 7, and the elastic supporting force of the elastic element 9 can ensure that the abutting block 8 has a good fixing effect on the extension part 7, thereby ensuring that the position of the extension part 7 is fixed after movement.

[0029] Among them Figure 2-Figure 4 As shown, a pushing member 10 is slidably provided on the support body 6 for pushing the abutment block 8 to move in a direction away from the extension portion 7. The pushing member 10 is slidably connected to the abutment block 8, and a slope is provided on the abutment surface between the pushing member 10 and the abutment block 8. The slope is used to achieve the effect of pushing the abutment block 8 to move, and the abutment block 8 is provided with an arc abutment point for abutting the slope. The arc abutment point is used to reduce the friction resistance when the pushing member 10 pushes the abutment block 8 to move, and the pushing member 10 is connected to a pulling rope 11, which extends to the outside of the support body, so that the user can operate it easily by pulling the rope 11.

[0030] At the same time, two supporting legs 4 are provided and are symmetrically arranged on the base 2. Two pulling ropes 11 extend to one end of the outer side of the supporting body and are fixedly connected with a card joint 16. One of the two card joints 16 is provided with a slot and the other has a plug. The plug is embedded in the slot to realize the disassembly connection of the two card joints 16. After the two card joints 16 are connected, it is convenient for the user to tighten the two pulling ropes 11 at the same time, thereby improving the convenience of the user in adjusting the length of the supporting leg 4.

[0031] like Figure 3 and Figure 7 As shown, a protrusion 12 for limiting the rotation angle of the support body 6 is fixedly provided on the rotating block 3. The protrusion 12 is used to provide a support point for the support body 6 to ensure that the position of the support body 6 will not rotate arbitrarily when the support body 6 is subjected to force. In addition, a groove corresponding to the position of the protrusion 12 is opened on the support body 6. The groove is used to limit the activity space of the support body 6 to ensure the stability of the overall structure.

[0032] like Figure 3 and Figure 6As shown, a gear 13 is fixedly provided on the rotating shaft that is rotatably connected to the rotating block 3 and the base 2, and a clamping piece 14 for clamping the gear 13 slides inside the base 2. A rack-like structure is fixedly provided on the side of the clamping piece 14 close to the gear 13. The position of the gear 13 is fixed by clamping the gear 13 with the rack-like structure. Two openings 15 are provided on the base 2 along the fore and aft directions of the sliding of the clamping piece 14. The clamping piece 14 is pushed to move left and right by inserting fingers into the two openings 15, thereby controlling the connection and separation of the clamping piece 14 and the gear 13.

[0033] At the same time, a shrinkage structure is provided at the opening 15 to prevent the clamping member 14 from falling off.

[0034] like Figure 1 As shown, the base 2 is arranged on the cutting gas pipe of the gas cutting gun 1 and is located at the end of the cutting gas pipe away from the nozzle, so that after the support leg 4 is unfolded, the support leg 4 is close to the switch of the gas cutting gun 1, which is convenient for the user to transfer the weight to the support leg 4 and improve the supporting effect.

[0035] Working principle: When using the gas cutting gun 1, first rotate the supporting foot 4 to put down the supporting foot 4, and then rotate the rotating block 3 through the supporting foot 4 to make the two supporting feet 4 open to a suitable angle, and then push the clamping piece 14 to move so that the clamping piece 14 contacts the gear 13, and clamp the gear 13 to fix the angle between the two supporting feet 4, and then pull the two clamping joints 16 to connect, and then hold the two supporting feet 4 with the other hand to press the connection between the two clamping joints 16 to drive the pulling rope 11 to move outward, and then pull the rope 11 to pull the pushing piece 10 to push the abutment block 8 to move away from the extension part 7, release the position fixation of the extension part 7, and then the extension part 7 can be adjusted to move to a suitable position, and then release the external force on the pulling rope 11, so that the elastic element 9 pushes the abutment block 8 to reset its position, thereby fixing the position of the extension part 7.
