Description

Technical Field

[0001] This utility model relates to the field of disc blade processing technology, specifically a welding device for disc blade processing. Background Technology

[0002] Slitting machine blades, also known as disc blades, are a type of slitting tool used in slitting equipment in the metal sheet industry. They are named for their two sets of blades that interlock longitudinally to cut the metal, and also for their disc-shaped shape. During the welding process, corresponding support structures are needed to provide auxiliary support for larger blades to prevent deformation.

[0003] According to a welding device for processing disc blades disclosed in Chinese Patent Publication No. CN219561877U, the patent uses a telescopic cylinder to raise the second support plate to the same horizontal plane height as the first support plate. The main support plate, the first support plate and the second support plate are formed on the same horizontal plane, which facilitates the lifting of the component after the blade is welded, ensures the welding effect, and prevents the blade from deforming. At the same time, the space occupied is reduced by retraction.

[0004] However, this patent has certain shortcomings in actual use. Since the blade needs to be installed on a circular hollow shaft, the patent only provides joint support for the blade and the hollow shaft, and cannot easily position the hollow shaft, which can easily affect the welding process. In addition, the use of multiple linkage structures is not conducive to later maintenance. In this regard, this application provides a welding device for processing disc blades to solve the above problems. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 3This utility model provides a technical solution: a welding device for processing disc blades, including a welding table 1, a welding assembly mounted on the top of the welding table 1, and a positioning support mechanism 300 mounted on the top of the welding table 1; through the cooperation between the welding torch 203 on the top of the welding table 1 and the positioning support mechanism 300, the structural fit can be simplified and the welded parts can be stably supported and positioned, so that the hollow shaft of the welding disc blade can be positioned inside the welding space, which is convenient for the workers to weld and fix the disc blade sleeved on the outside, and can support the disc blade so that it is not easily deformed during the welding process, thereby ensuring the stability and effectiveness of the welding, thus effectively improving the practicality of the welding device for processing disc blades.

[0025] In this embodiment, the positioning support mechanism 300 is a structure used to support the disc blade and the hollow shaft cylinder.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning support mechanism 300 includes a fixed plate 301 fixed to the top of the welding table 1, an adjustment box 302 fixed to the top of the welding table 1, a lead screw 303 rotatably connected to the inner side of the adjustment box 302 via bearings, a positioning rod 304 fixed to the inner side of the adjustment box 302, a moving block 305 threaded to the outer side of the lead screw 303, a moving plate 306 fixed to the top of the moving block 305, two rotating pressure blocks 307 rotatably connected to the opposite side of the fixed plate 301 and the moving plate 306 via bearings, and two inner support rods 308 passing through and fixed to the opposite side of the two rotating pressure blocks 307. The positioning support mechanism 300 also includes a cylinder 309 fixedly installed on the top of the welding table 1, a V-shaped support plate 310 fixedly installed on the output shaft of the cylinder 309, four guide rods 311 fixed to the bottom of the V-shaped support plate 310, four linear slide cylinders 312 fixed to the bottom of the welding table 1, and a handwheel 313 fixedly installed on the right end of the lead screw 303.

[0027] It should be noted that the bottom end of the guide rod 311 passes through the welding table 1 and the top of the corresponding linear slide cylinder 312, and passes through the inner side of the corresponding linear slide cylinder 312 and extends to its bottom, so that the guide rod 311 can guide the lifting and lowering of the V-shaped support plate 310. The handwheel 313 is located on the right side of the adjustment box 302, and the output shaft of the handwheel 313 passes through the right side of the adjustment box 302 and is fixedly connected to the right end of the lead screw 303, so that the handwheel 313 can easily rotate the lead screw 303.

[0028] In addition, the top of the adjustment box 302 is open, and the right end of the positioning rod 304 passes through the left side of the moving block 305, so that the moving block 305 can be limited by the positioning rod 304, and then it can be moved by the threaded connection of the lead screw 303. The two inner support rods 308 are symmetrically distributed on the left and right, and the inner support rods 308 are located above the V-shaped support plate 310, so that the inner support rods 308 can support the shaft cylinder connected to the disc blade.

[0029] In this embodiment, the welding assembly is a structure used for welding the disc blade and the hollow shaft.

[0030] like Figure 1 As shown, the welding assembly includes an L-shaped support plate 201 fixed to the top of the welding table 1, two hooks 202 fixedly installed on the inner top wall of the L-shaped support plate 201, and a welding torch 203 hung between the inner sides of the two hooks 202.

[0031] It should be noted that the V-shaped support plate 310 is located inside the L-shaped support plate 201, so that the welding parts can be welded inside the L-shaped support plate 201. The welding assembly also includes a welding machine placed outside the welding table 1, and the welding machine is connected to the welding gun 203 through wires, so that the welding gun 203 can perform welding work normally.

[0032] The working principle of the above embodiments is as follows:

[0033] When welding the disc blade onto the hollow shaft cylinder, the disc blade is fitted onto the outside of the hollow shaft cylinder, and then the hollow shaft cylinder is fitted onto the outside of the left inner support rod 308, with the left side of the hollow shaft cylinder and the right side of the left rotating pressure block 307 abutting against each other. Turning the handwheel 313 causes the lead screw 303 to rotate. Under the limiting action of the positioning rod 304, the moving block 305 can drive the moving plate 306 to move, thereby allowing the right inner support rod 308 to also be inserted into the inside of the hollow shaft cylinder, and the right side of the hollow shaft cylinder and the right rotating pressure block 307 abutting against each other. The left side of block 307 abuts to limit the hollow shaft cylinder. Then, according to the actual specifications of the disc blade, the stroke lifting distance of cylinder 309 is limited. Cylinder 309 is activated to push V-shaped support plate 310 upward, so that the inner side of V-shaped support plate 310 and the outer side of disc blade are in contact, thus completing the support work for disc blade. Since the contact point between the blade and the inner wall of V-shaped support plate 310 is small, it will not affect the normal rotation of the shaft cylinder during the welding process, thus facilitating efficient and stable welding work.

[0034] Compared with existing technologies, this welding device for processing disc blades simplifies the structural fit and provides stable support and positioning for the welded parts through the cooperation between the welding torch 203 on the top of the welding table 1 and the positioning support mechanism 300. This allows the hollow shaft of the welding disc blade to be positioned inside the welding space, facilitating the welding and fixing of the disc blade fitted on the outside by the operator. It also supports the disc blade, preventing it from deforming during the welding process, thus ensuring the stability and effectiveness of the welding. This effectively improves the practicality of the welding device for processing disc blades and solves the problem that existing welding devices for processing disc blades are inconvenient for stably supporting and positioning circular welding hollow shafts.
