Technical Field
[0001] This utility model relates to the field of hoop production technology, specifically a plasma cutting device for hoop processing. Background Technology
[0002] A plasma cutting machine is an industrial device that uses a high-temperature, high-speed plasma arc to melt and cut conductive materials. It has the advantages of fast cutting speed and high cutting precision, and is especially suitable for cutting materials such as clamps.
[0003] During the processing of clamps, a plasma cutting machine is needed to cut the clamp flat steel into equal parts. Due to the cutting characteristics of the plasma cutting machine, a natural bevel will be produced at the cut, which is wider at the top and narrower at the bottom. For the connecting surfaces of the clamps, if extremely high precision is required, a small machining allowance may need to be reserved. After cutting, slight grinding is required. During grinding, the clamp flat steel needs to be repositioned and clamped, which affects processing efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a plasma cutting device for processing clamps. By setting movable clamping seats on both sides of the plasma cutting table and setting a lifting grinding structure directly below the center of the cutting table, after the clamp flat steel is cut into sections, the lifting grinding structure is driven to grind the cut edges of the clamp flat steel at both ends in one go, avoiding the cut edge being wider at the top and narrower at the bottom. Furthermore, by setting a torsion structure, the opening width between the two sets of clamping seats can be controlled according to the rotation angle of the rotating motor, so that sanding discs of different thicknesses can be used for cutting edge grinding.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a plasma cutting device for processing clamps, comprising a base, a plasma cutting assembly disposed above the base, a cutting table for supporting the cutting of clamp flat steel being fixed to the upper surface of the base by screws, clamping seats for pressing the two sections of clamp flat steel after cutting being disposed on both sides of the cutting table, a through groove corresponding to the cutting position of the clamp flat steel being opened on the upper surface of the cutting table, a lifting grinding structure for grinding the cutting position of the two sections of clamp flat steel being disposed in the through groove, and a torsion structure for pushing the two sets of clamping seats to the sides to expose the cut of the clamp flat steel being installed on the upper surface of the base.
[0006] Preferably, the torsion structure includes a support block and a rotating motor that drives the support block to rotate. The rotating motor is installed below the base, and a rotating rod is fixed to the output end of the rotating motor. The rotating rod passes through the base and is rotatably connected to the base. The rotating rod is fixedly connected to the middle of the support block.
[0007] Preferably, the torsion structure further includes a spring that causes the clamping seat to return to its original position after being opened. A fixing plate is fixed to the upper surface of the base by screws. One end of the spring is fixedly connected to the fixing plate, and the other end of the spring is fixedly connected to one side of the clamping seat. A slide rail is installed on the upper surface of the base, and the clamping seat is slidably connected to the slide rail.
[0008] Preferably, the cutting table has a limiting groove in the middle for inserting the clamping flat steel, the two sides of the clamping flat steel are in contact with the inner wall of the limiting groove, and the through groove passes through the limiting groove.
[0009] Preferably, the lifting grinding structure includes a lifting cylinder, which is installed at the bottom of the base. The telescopic end of the lifting cylinder is fixed with a mounting seat. A sanding disc is rotatably connected inside the mounting seat. A grinding motor is installed on one side of the mounting seat. The telescopic end of the grinding motor is fixedly connected to the rotating shaft of the sanding disc. The outer wall of the sanding disc extends into the through groove.
[0010] Preferably, the clamping seat includes a slide and a clamping structure disposed within the slide;
[0011] The slide block has a slot on one side for inserting a clamping flat steel bar. The clamping structure includes an electric push rod and a pressure plate fixed to the telescopic end of the electric push rod. The electric push rod is installed above the slide block, and the pressure plate is located in the slot.
[0012] Preferably, the plasma cutting assembly includes a plasma cutting head and a Y-axis displacement stage for driving the plasma cutting head to move. A column is fixed above the base, and a displacement cylinder for driving the plasma cutting head to rise and fall is installed on the top of the column. The Y-axis displacement stage is installed at the telescopic end of the displacement cylinder.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model addresses the problem of the "wider top and narrower bottom" natural slope of the cut caused by plasma cutting. It utilizes a sanding disc in a lifting grinding structure to grind the cut, which can remove the slope and make the two sides of the cut flat and vertical. After the clamp flat steel is cut, there is no need to disassemble the cut steel segment. The cut can be directly ground in the same clamping state, which improves the continuity of processing and thus improves the overall efficiency of clamp production.
[0015] 2. The torsion structure of this utility model is not only used to open up the clamping seat to expose the cut, but the rotation angle of the support block driven by the rotating motor can control the opening width between the two sets of clamping seats, so that the device can adapt to sanding discs of different diameters or thicknesses. Whether using a thinner fine grinding sanding disc or a thicker coarse grinding sanding disc, the opening width can be adjusted to ensure that the sanding disc can effectively contact and grind the cut, thereby improving the device's adaptability to different processing requirements.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-6This utility model provides a technical solution: a plasma cutting device for processing clamps, including a base 1, a plasma cutting assembly 2 disposed above the base 1, a cutting table 4 for supporting the cutting of clamp flat steel 3 fixed to the upper surface of the base 1 by screws, clamping seats 5 for pressing the two sections of clamp flat steel 3 after cutting on both sides of the cutting table 4, a through groove 6 corresponding to the cutting position of the clamp flat steel 3 opened on the upper surface of the cutting table 4, a lifting grinding structure 7 for grinding the cutting position of the two sections of clamp flat steel 3 disposed in the through groove 6, and a torsion structure 8 installed on the upper surface of the base 1 for pushing the two sets of clamping seats 5 to the sides to expose the cut of the clamp flat steel 3.
[0029] The base 1 serves as the overall support platform, and the cutting table 4 is fixed to the upper surface of the base 1 with screws. The limiting groove 807 in the middle of the cutting table 4 is used to place the clamping flat steel 3, and the side walls restrict the horizontal displacement of the flat steel. During cutting, the plasma cutting head 201 is aligned with the through groove 6 on the upper surface of the cutting table 4, and the through groove 6 also provides an upward channel for the sand disc 703 for subsequent grinding.
[0030] The torsion structure 8 includes a support block 801 and a rotary motor 802 that drives the support block 801 to rotate. The rotary motor 802 is installed below the base 1, and a rotating rod 803 is fixed to the output end of the rotary motor 802. The rotating rod 803 passes through the base 1 and is rotatably connected to the base 1. The rotating rod 803 is fixedly connected to the middle of the support block 801. After cutting, the torsion structure 8 pushes the two sets of slide blocks 501 to slide to both sides along the slide rail 806, causing the two fixed clamp flat steel sections 3 to separate, exposing the cut. Specifically: the rotary motor 802 starts, driving the rotating rod 803 to rotate, causing the support block 801 to rotate; the outer rounded corner of the support block 801 contacts the side wall of the clamping seat 5, forcing the slide block 501 to slide to both sides along the slide rail 806.
[0031] By controlling the rotation angle of the rotating motor 802, the unfolding angle of the support block 801 can be adjusted, thereby controlling the opening distance of the two sets of clamping seats 5 to adapt to sand discs 703 of different thicknesses.
[0032] The torsion structure 8 also includes a spring 804 that allows the clamping seat 5 to return to its initial position after being opened. A fixing plate 805 is fixed to the upper surface of the base 1 by screws. One end of the spring 804 is fixedly connected to the fixing plate 805, and the other end is fixedly connected to one side of the clamping seat 5. A slide rail 806 is mounted on the upper surface of the base 1, and the clamping seat 5 is slidably connected to the slide rail 806. After the torsion structure 8 releases its thrust, the spring 804 pulls the slide seat 501 back to its initial position along the slide rail 806. Specifically, when the rotating motor 802 reverses, the support block 801 retracts, and the spring 804 pulls the clamping seat 5 and the slide seat 501 back to its initial position along the slide rail 806.
[0033] The cutting table 4 has a limiting groove 807 in the middle for inserting the clamping flat steel 3. The two sides of the clamping flat steel 3 are in contact with the inner wall of the limiting groove 807, and the through groove 6 passes through the limiting groove 807.
[0034] The lifting grinding structure 7 includes a lifting cylinder 701, which is installed at the bottom of the base 1. A mounting base 702 is fixed to the telescopic end of the lifting cylinder 701. A sanding disc 703 is rotatably connected inside the mounting base 702. A grinding motor 704 is installed on one side of the mounting base 702. The telescopic end of the grinding motor 704 is fixedly connected to the rotating shaft of the sanding disc 703. The outer wall of the sanding disc 703 extends into the through groove 6. The lifting cylinder 701 pushes the mounting base 702 upward, causing the sanding disc 703 to embed into the through groove 6 of the cutting table 4 and contact the cut. Simultaneously, the grinding motor 704 starts, driving the sanding disc 703 to rotate, synchronously grinding the cut edges of the flat steel on both sides. After grinding is completed, the lifting cylinder 701 retracts, causing the sanding disc 703 to descend below the through groove 6, disengaging from the cutting area.
[0035] The clamping seat 5 includes a slide 501 and a clamping structure disposed within the slide 501;
[0036] The slide block 501 has a slot 502 on one side for inserting the clamping flat steel 3. The clamping structure includes an electric push rod 504 and a pressure plate 503 fixed to the telescopic end of the electric push rod 504. The electric push rod 504 is installed above the slide block 501, and the pressure plate 503 is located inside the slot 502. The clamping flat steel 3 is inserted into the slot 502 of the slide block 501 at both ends, and the electric push rod 504 drives the pressure plate 503 to press down, fixing the flat steel in the slot 502.
[0037] The plasma cutting assembly 2 includes a plasma cutting head 201 and a Y-axis displacement stage 202 that drives the plasma cutting head 201 to move laterally to the cutting position. The Y-axis displacement stage 202 is a linear displacement stage, capable of moving the plasma cutting head 201 back and forth to achieve linear cutting of the clamping flat steel 3. A column 203 is fixed above the base 1, and a displacement cylinder 204 that drives the plasma cutting head 201 to rise and fall is installed on the top of the column 203. The Y-axis displacement stage 202 is installed at the telescopic end of the displacement cylinder 204. The displacement cylinder 204 drives the plasma cutting head 201 to descend, and the high-temperature plasma arc penetrates the clamping flat steel 3 to complete the cutting, naturally forming a slant that is wider at the top and narrower at the bottom. After cutting, the displacement cylinder 204 raises the cutting head, and the Y-axis displacement stage 202 moves the cutting head away to avoid the grinding area.
[0038] When in use, the clamp flat steel 3 is placed into the limiting groove 807 of the cutting table 4, and the electric push rod 504 of the clamping seat 5 drives the pressure plate 503 to lock the two ends of the flat steel.
[0039] The Y-axis displacement stage 202 and the displacement cylinder 204 work together to position the cutting head and complete the cutting at the through groove 6. After cutting, the displacement cylinder 204 lifts the cutting head and the Y-axis displacement stage 202 moves the cutting head away to avoid the grinding area.
[0040] The rotating motor 802 drives the support block 801 to rotate, opening the clamping seat 5 to separate the two sections of clamp flat steel 3, exposing the cut to the through groove 6;
[0041] The lifting cylinder 701 lifts the sanding disc 703 into the through groove 6, and the grinding motor 704 drives the sanding disc 703 to rotate, grinding two cuts at once to make the cuts flush.
[0042] The lifting cylinder 701 drives the sanding disc 703 to descend and exit, the rotating motor 802 reverses, the side wall of the clamping seat 5 is no longer subjected to the squeezing force, and it is reset to the initial position by the spring 804. The initial position of the clamping seat 5 is to be pressed against one side of the fixed seat. The polished clamping flat steel 3 is then removed.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
