Description

Technical Field

[0001] The invention relates to the technical field of silver wire cutting equipment, in particular to an automatic silver wire feeding and cutting mechanism for a spot welding machine. Background Art

[0002] When the spot welding machine is performing welding on the operating table, the silver wire will be automatically sent to the operating table through the device, and will be limited and cut by the silver wire cutting device. However, the existing cutting device cannot guide the silver wire during use, and it will deviate during transportation, causing the silver wire to bend to a certain extent, affecting the welding work. At the same time, if there are fewer silver wires wound on the coil, the silver wire will contact the operating table during transportation, causing certain wear and tear, which will affect the welding work. In addition, the tool will cause metal fatigue when used for a long time, and the tool will also collapse or break during the cutting operation due to overheating, causing If the silver wire has an uneven cut edge, if manual cooling is used, the cutting work needs to be stopped for cooling, which will delay the progress of the work. In addition, there will be oil and stains on the silver wire. If it is not wiped during welding, it will cause flashes, splashes, etc., affecting the progress of the welding work. During the welding operation, if the tool is damaged, it needs to be replaced. During the actual operation, the tool will be hot. Replacing it at that time can easily cause injury to the operator's hands. If it is replaced after cooling, it will affect the progress of the work. Therefore, the present application provides an automatic silver wire feeding and cutting mechanism for a spot welding machine to meet the needs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic silver wire cutting mechanism for a spot welding machine to solve the problem that the existing cutting device cannot guide the silver wire during use, and the deviation phenomenon will occur during transportation, causing the silver wire to bend to a certain extent, affecting the progress of welding work. At the same time, if the silver wire wound on the coil is less, the silver wire will contact the operating table during transportation, causing certain wear, which will affect the progress of welding work. In addition, the tool will cause its metal fatigue when used for a long time, and the tool will also collapse and break during the overheating cutting operation, causing the silver wire to be uneven. If the temperature is lowered manually, the cutting work needs to be stopped for cooling treatment, which will delay the progress of the work, and there will be oil stains and stains on the silver wire. If it is not wiped during welding work, it will cause flash, splashing and the like, affecting the progress of welding work. In the welding operation, if the tool is damaged, it needs to be replaced, and in the actual operation process, the tool will be hotter, and it is easy to cause the operator's hand to be injured when replacing it at that time.

When the second U-shaped guide plate expands outward, it will drive the upper port gap of the second wiping pad 322 to expand outward, further causing the silver wire to enter the second wiping pad 322. When the first flange and the second flange are not subjected to force, the first U-shaped guide plate and the second U-shaped guide plate will return to their original state. Compared with the existing automatic silver wire feeding and cutting device, the present invention realizes the limiting guiding of the silver wire through the above structure, thereby avoiding its position deviation during transportation, and also avoiding the outer wall wear of the silver wire when it contacts the operating table, thereby affecting welding.

A group of water blocking components 335 are provided on both side walls of the V-shaped groove 331. A drainage groove 333 opened in the bottom plate 311 is provided below the liquid groove 334. One end of the drainage groove 333 passes through the bent end of the bottom plate 311. The drainage groove 333 is arranged in a bent shape. The arrangement of the drainage groove 333 is to facilitate the drainage of the waste liquid after cooling. A through opening 332 connected to the drainage groove 333 is provided at the bottom of the V-shaped groove 331 to facilitate the waste liquid after cooling to enter the drainage groove 333 through the through opening 332 for collection.

[0044] The water blocking component 335 includes a water outlet hole 336 opened on the side wall of the V-shaped groove 331, and the water outlet hole 336 is connected to the liquid groove 334.

[0045] The two side walls of the V-shaped groove 331 are arranged in a sloped shape. In order to adapt to the use of the tool and to facilitate the diversion of the waste liquid so that it can quickly enter the through-port 332, the drainage groove 333 is arranged in an inclined shape, and its height decreases from one end away from the bend to the other end. In order to facilitate the rapid collection of waste liquid and avoid the accumulation of liquid, the bottom wall of the liquid groove 334 is arranged in an inclined shape, and the height of one side close to the V-shaped groove 331 is lower than the height of the other side. In order to facilitate the cooling liquid to quickly flow into the water outlet 336, the liquid groove 33 The T-shaped block 338 is composed of a water storage annular groove and a water outlet annular groove, the water outlet annular groove is connected to the water outlet hole 336, the T-shaped block 338 includes a blocking plate and a guide rod fixedly connected to each other, the blocking plate is located in the liquid groove 334 and fits with the liquid groove 334, the diameter of the blocking plate is larger than the diameter of the water outlet hole 336, the blocking plate is made of rubber material, in order to facilitate the blocking of the cooling liquid to prevent it from overflowing, one end of the guide rod is arranged in an arc-shaped slope, in order to facilitate the tool to push the guide rod to avoid the situation that the tool cannot move down.

Compared with the existing automatic silver wire cutting device, the present invention realizes the cooling work during the tool cutting operation through the above structure, thereby avoiding the metal fatigue of the tool caused by long-term use, and further avoiding the chipping and breakage of the tool during the cutting operation due to overheating, and further avoiding the uneven silver wire cut that affects welding, and also avoiding stopping the cutting work to cool the tool and delaying the work progress.

[0047] like Figure 3 , Figure 4 As shown, the first wiping assembly 34 includes a first wiping pad 341 fixedly connected to the first cardboard 312. In order to facilitate wiping the silver wire, a supplementary cavity is opened in the first wiping pad 341, and a second cardboard supplementary component 342 is provided in the supplementary cavity. The second cardboard supplementary component 342 is provided to supplement the first wiping pad 341 so that the silver wire and the first wiping pad 341 are kept in a fitted state. The second cardboard supplementary component 342 includes a first U-shaped long tube 343 fixedly connected to the bottom of the supplementary cavity.

[0048] By setting the first wiping component 34, during use, when the silver wire is clamped in the first clamping plate 312, the first clamping plate 312 will drive the first wiping pad 341 to deform when it is deformed, and will also cause the connecting piece 344 to deform, which will drive the second U-shaped long tube 345 to open, and the silver wire will enter the first wiping pad 341. When the first clamping plate 312 is not subjected to force, it will drive the first wiping pad 341 to return to its original position, and then the connecting piece 344 will drive the second U-shaped long tube 345 to return to its original position, and further the first wiping pad 341 will be in close contact with the silver wire. When the silver wire moves, it will rub against the first wiping pad 341, and the first wiping pad 341 will wipe the oil stains and stains on the silver wire. Compared with the existing automatic silver wire feeding and cutting device, the present invention realizes the wiping of the silver wire through the above structure, and avoids the influence of oil stains and stains on the welding work.

[0049] like Figure 3 , Fig.10 As shown, the cutting assembly includes a lifting component 38 and a cutting unit 39 connected to each other, and the lifting component 38 is connected to the bottom plate 311; the lifting component 38 includes a mounting frame fixedly connected to the top of the bottom plate 311, and an electric push rod is installed on the mounting frame; the cutting unit 39 includes an L-shaped connecting rod 391 fixedly connected to the telescopic end of the electric push rod, and the other end of the L-shaped connecting rod 391 is fixedly connected to a screw rod, the diameter of the screw rod is smaller than the rod diameter of the L-shaped connecting rod 391, and a square plate 392 is sleeved on the screw rod, and one end of the screw rod is screwed with a threaded cover that conflicts with the side wall of the square plate 392. A group of cutting units arranged symmetrically are provided on the square plate 392, which are arranged by the L-shaped connecting rod 391, the screw rod and the threaded cover for use with the square plate 392, so as to facilitate the fixing of the square plate 392 and the rotation of the square plate 392, and further facilitate the rotation of the cutting unit, and further by rotating the cutting unit, the damaged cutting unit is replaced with a new cutting unit to avoid burning the operator's hand due to the high temperature of the cutting unit during replacement.

[0050] The cutting unit includes a cutter 395 disposed above the V-shaped groove 331, and a first square hole opened on the side wall of the square plate 392. The cutter 395 fits the square plate 392, and a second square hole is opened on the side wall of the cutter 395. A second L-shaped square rod 394 inserted into the second square hole is provided on one side of the cutter 395, and a first L-shaped square rod 393 inserted into the second square hole is provided on the other side of the cutter 395.

One end of the square rod 394 is fixedly connected to the second rack, the first rack is in meshing state with the second rack and inserted into the first square hole, a bolt 396 is screwed to the side wall of the square plate 392 away from the tool 395 through a screw hole, and the bolt 396 is in conflict with the second rack, and the square plate 392, the first L-shaped square rod 393, the second L-shaped square rod 394 and the bolt 396 are arranged in coordination to facilitate the limiting and fixing of the tool 395 and to facilitate the replacement of the tool 395.

[0051] By setting up the cutting assembly, when in use, if the damaged tool 395 needs to be replaced, the threaded cover can be screwed so that it does not conflict with the square plate 392, and then the square plate 392 is rotated 180°, so that the upper tool 395 corresponds to the V-shaped groove 331, and then the threaded cover is screwed to restore it to its original position, so that the square plate 392 can be locked. If the cooled and damaged tool 395 needs to be replaced, the bolt 396 can be screwed to make it away from the second rack, and then the second L-shaped square rod 394 and the first L-shaped square rod 393 are pulled away from each other, and made to pass through the second square hole, so that the tool 395 can be removed, and then a new tool 395 is placed, and it can be installed according to the above working principle. Compared with the existing automatic silver wire cutting device, the present invention realizes rapid replacement of the tool through the above structure, and at the same time, the damaged tool can be replaced after cooling, thereby avoiding delaying the cutting process and avoiding the situation where the operator's hand will be burned when it is replaced in a hot state.

[0052] The working principle provided by the present invention is that during use, the pipeline of the liquid supply equipment is first connected to the water injection pipe 35, and liquid is supplied thereto, the cooling liquid will enter the water storage annular groove, and then enter the water outlet annular groove, and then the silver wire is straightened and placed on the first flange and the second flange for pressing, which will cause the first flange and the second flange to turn outward, and at the same time, the first flange will drive the first U-shaped guide plate to turn outward and deform, and the second flange will drive the second U-shaped guide plate to turn outward and deform, which will cause the upper port gap of the first U-shaped guide plate and the second U-shaped guide plate to expand outward, and when the second U-shaped guide plate expands outward, it will drive the upper port gap of the second wiping pad 322 to expand outward, and when the first U-shaped guide plate turns outward and deforms, it will drive the first wiping pad 341 to deform, and at the same time, it will also cause the connecting The deformation of the connecting piece 344 will drive the opening of the second U-shaped long tube 345 to open, and then the silver wire will enter the first U-shaped guide plate, and also enter the first wiping pad 341 and the second wiping pad 322. When the first flange and the second flange are not subject to force, the first U-shaped guide plate and the second U-shaped guide plate will return to their original state, driving the first wiping pad 341 to return to its original position, and then the connecting piece 344 will drive the second U-shaped long tube 345 to return to its original position, and further, the inner walls of the first wiping pad 341 and the second wiping pad 322 will be tightly attached to the silver wire. During the feeding process of the silver wire, the silver wire will rub against the first wiping pad 341, and the first wiping pad 341 will wipe the oil stains and stains on the silver wire, and the second wiping pad 322 will perform a second round of wiping.

[0053] When cutting is required, the telescopic rod of the electric push rod will push the L-shaped connecting rod 391 to move downward, which will then cause the L-shaped connecting rod 391 to drive the square plate 392 to move downward, and further drive the first L-shaped square rod 393, the second L-shaped square rod 394 and the cutter 395 to move downward. The cutter 395 will contact the silver wire and cut it, and also make it enter the V-shaped groove 331. The cutter 395 will squeeze the guide rod during the downward movement. When the guide rod is squeezed, The guide rod moves toward the water outlet 336, which in turn causes the annular spring piece 339 to deform during extrusion, and also causes the sealing plate to move toward the liquid tank 334, causing the water outlet 336 to be connected with the liquid tank 334, and the cooling liquid will enter the water outlet 336 through the overflow hole, and the cooling liquid will enter the V-shaped groove 331 and contact the tool 395, and the cooled waste liquid will enter the opening 332 through the V-shaped groove 331, and then enter the drainage groove 333.

[0054] If the damaged tool 395 needs to be replaced, the threaded cover can be screwed so that it does not interfere with the square plate 392, and then the square plate 392 is rotated 180°, so that the upper tool 395 corresponds to the V-shaped groove 331, and then the threaded cover is screwed to restore it to its original position, so that the square plate 392 can be locked. If the cooled and damaged tool 395 needs to be replaced, the bolt 396 can be screwed to keep it away from the second rack, and then the second L-shaped square rod 394 and the first L-shaped square rod 393 are pulled away from each other, and they are removed from the second square hole, so that the tool 395 can be removed, and then a new tool 395 can be placed and installed according to the above working principle.
