Description

Technical Field

[0001] This utility model relates to the field of tungsten electrode processing equipment, and in particular to an automatic tungsten electrode straightening device. Background Technology

[0002] Tungsten electrodes have a high melting point, are corrosion-resistant, and have high density. They also possess excellent thermal and electrical conductivity. Widely used in welding, tungsten electrodes are crucial components in tungsten inert gas (TIG) welding. Their shape and quality directly affect the stability of the arc and the quality of the weld. Finished tungsten electrodes are typically thin rods about 20cm long. Before processing, they are usually coiled filaments, which need to be straightened and cut into long rods of 3-10m, and then further cut into several finished products of different specifications.

[0003] When existing equipment straightens and cuts coiled tungsten electrode wires into 3-10m long bars, it requires manual labor at the exit end to hold one end of the tungsten electrode bar and pull it to prevent it from bending due to lack of support at one end after straightening. This manual holding and pulling requires walking back and forth, is labor-intensive, and is prone to wobbling and instability. Furthermore, because tungsten has high strength, the tungsten electrode wire needs to be heated during uncoiling and straightening, resulting in a high temperature for the straightened tungsten bar, posing a certain safety hazard to manual handling. These are existing problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an automatic tungsten electrode straightening device that automatically straightens and pulls the electrode to complete the cutting process.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic tungsten electrode straightening device includes a base, on which a feeding wheel, a heating box, a straightening wheel, a cutting mechanism, and a traction mechanism are sequentially arranged. The cutting mechanism includes a support frame, a lifting platform, and a lifting blade. A hydraulic cylinder is fixed on the support frame, and a blade holder is fixed to the output end of the hydraulic cylinder. The lifting blade is fixed to the blade holder. A second hydraulic cylinder is fixed to the base directly below the lifting blade, and the lifting platform is fixed to the output end of the second hydraulic cylinder. The traction mechanism includes a slide and a clamping device. The slide is disposed on one side of the base, and the clamping device is fixed to the slide. A liftable receiving frame is also provided on the base directly below the clamping device.

[0007] Further optimized, the straightening wheels include two sets, each set including upper and lower rollers.

[0008] Further optimized, the lifting platform is provided with two grooves, one corresponding to the tungsten electrode and the other corresponding to the lifting blade.

[0009] Further optimized, the base is provided with two third hydraulic cylinders, and a horizontal plate is fixed on the output end of the third hydraulic cylinders. Several receiving racks are fixed on the horizontal plate.

[0010] Furthermore, the receiving racks are all provided with arc-shaped notches.

[0011] Further optimized, a linear slide is fixed on the base, and the slide block is fixed on the linear slide.

[0012] In a further optimized manner, the clamping device includes a fixed plate, a lead screw, a slide rod, a motor, and two clamping blocks. The bottom of the fixed plate has a sliding groove, in which the lead screw and the slide rod are disposed. The motor is fixed to one end of the fixed plate, and the output shaft of the motor is connected to the lead screw. The two clamping blocks are disposed on the lead screw and the slide rod, and the output of the motor drives the two clamping blocks to move towards each other.

[0013] Further optimized, the inner side of the clamping block is provided with a tapered clamping groove.

[0014] Further optimized, it also includes a material placement rack and several material placement plates, one end of which is fixed to a support frame, and the other end of which is suspended at an upward angle between receiving racks, and the material placement plates are evenly distributed between the receiving racks.

[0015] The beneficial effects of this utility model are:

[0016] This novel device includes a feeding wheel, a heating box, a straightening wheel, a cutting mechanism, and a traction mechanism. The feeding wheel unwinds and feeds the tungsten electrode rod. The heating box rapidly heats the tungsten electrode rod. The straightening wheel straightens the heated tungsten electrode rod. The cutting mechanism cuts the tungsten electrode rod into 3-10m long rods. The traction mechanism includes a slide and a clamping device. A linear slide moves the clamping device back and forth on the base. The clamping device holds the traction tungsten electrode rod and provides support to one end of the rod to prevent it from sagging and bending, thus completing the straightening and cutting process.

[0017] This new type of device also includes a receiving rack and a placing rack. After the traction mechanism pulls the tungsten electrode rod to the specified length, it stops. The receiving rack rises to support the tungsten electrode rod, and then the cutting mechanism completes the cutting. The traction mechanism continues to move a short distance to pull the tungsten electrode rod completely onto the receiving rack and releases the clamping block. The receiving rack resets, and during the reset process, the tungsten electrode rod is pushed onto the placing rack. This new type of device automatically receives and unloads materials, ensuring high safety, reducing manual intervention, and improving straightening efficiency. Attached Figure Description

[0026] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] like Figures 1-6 As shown, this utility model provides an automatic tungsten electrode straightening device, including a base 1. The base is sequentially equipped with a feeding wheel 2, a heating box 3, a straightening wheel 4, a cutting mechanism 5, and a traction mechanism 6. The feeding wheel 2 drives the unwinding and feeding of a coiled tungsten electrode rod. The heating box 3 electrically heats the tungsten electrode rod. The straightening wheel 4 straightens the tungsten electrode rod. The cutting mechanism intermittently cuts the tungsten electrode rod into long rods of specified lengths. The traction mechanism pulls and supports the long rods and assists in unloading. Both the feeding wheel and the straightening wheel are drive wheels, driven by a drive mechanism, which will not be described further.

[0028] like Figure 2As shown, the cutting mechanism 5 includes a support frame 51, a lifting platform 56, and a lifting blade 54. A hydraulic cylinder 52 is fixed on the support frame 51, and a blade holder 53 is fixed to the output end of the hydraulic cylinder. The lifting blade 54 is fixed on the blade holder 53. A second hydraulic cylinder 55 is fixed on the base 1 directly below the lifting blade 54. The lifting platform 56 is fixed to the output end of the second hydraulic cylinder 55. The lifting blade 54 and the lifting platform 56 move towards each other under the drive of the hydraulic cylinder to complete the cutting. The traction mechanism 6 includes a slide block 62 and a clamping device. The slide block 62 is disposed on one side of the base 1, and the clamping device is fixed on the slide block 62. A liftable receiving rack 7 is also provided on the base directly below the clamping device. The slide block drives the clamping device to reciprocate. After the clamping device clamps the tungsten electrode rod, it is pulled to the end of the base. The receiving rack is raised, and then the cutting mechanism cuts it. The clamping device pulls the rod to continue moving a short distance, completely pulling the tungsten electrode rod onto the receiving rack, and then the clamping block is released, and the receiving rack is reset.

[0029] In a preferred embodiment, the straightening wheel 4 includes two sets, each set including upper and lower rollers 41, and the straightening wheel 4 straightens the heated tungsten electrode rod.

[0030] As a preferred implementation method, such as Figure 2 As shown, the lifting platform 56 has two longitudinal and transverse grooves 561. One groove corresponds to the tungsten electrode rod 9 and is an arc-shaped groove to position the tungsten electrode and prevent it from shifting left and right during cutting. The other groove corresponds to the lifting blade 54 to ensure that the cutting mechanism completely cuts the tungsten electrode rod.

[0031] As a preferred implementation method, such as Figure 3 As shown, the base 1 is equipped with two third hydraulic cylinders 73. A horizontal plate 72 is fixed on the output end of the third hydraulic cylinder. Several receiving racks 7 are fixed on the horizontal plate. Each receiving rack 7 has an arc-shaped notch. After the cutting mechanism 5 cuts the tungsten electrode rod, the clamping device pulls the long rod to the receiving rack 7. The receiving rack 7 descends to automatically unload the material.

[0032] In a preferred embodiment, a linear slide 61 is fixed on the base 1, and the slide block 62 is fixed on the linear slide 61. The output of the linear slide 61 drives the slide block and the clamping device to reciprocate.

[0033] As a preferred implementation method, such as Figure 4 , 5As shown, the clamping device includes a fixed plate 63, a lead screw, a slide rod 66, a motor 64, and two clamping blocks 65. The bottom of the fixed plate 63 has a sliding groove, in which the lead screw and slide rod 66 are disposed. The motor 64 is fixed to one end of the fixed plate 63. The lead screw is rotatably connected in the sliding groove, and the slide rod 66 is fixedly connected in the sliding groove. The output shaft of the motor 64 is connected to the lead screw. The two clamping blocks are disposed on the lead screw and slide rod 66. The output of the motor 64 drives the two clamping blocks 65 to move towards each other, clamping the tungsten electrode rod.

[0034] In a preferred embodiment, the inner side of the clamping block 65 is provided with a conical clamping groove 651. The conical clamping groove can make the clamping more precise and stable and avoid clamping deviation.

[0035] As a preferred implementation method, such as Figure 1 , 3 As shown, it also includes a material placement rack 81 and several material placement plates 82. One end of the material placement plate 82 is fixed on the support frame 81, and the other end of the material placement plate 82 is suspended at an upward angle between the receiving racks 7. The material placement plates 82 are evenly distributed between the receiving racks. When the receiving rack receives the tungsten electrode rod and falls back to its original position, the tungsten electrode rod is pushed onto the material placement plate 82.

[0036] The more specific work steps are as follows:

[0037] 1. After the coiled tungsten electrode rod is unwound, it is heated, straightened by the straightening wheel 4, and extends out from the cutting mechanism 5;

[0038] 2. The clamping block 65 clamps the tungsten electrode rod and provides support for it. At the same time, the slide block 62 drives the clamping block to pull the tungsten electrode rod towards the end of the base 1.

[0039] 3. Once the clamping block pulls the tungsten electrode rod to the specified length, the slide 61, feeding wheel 2, and straightening wheel 4 stop moving, the receiving frame 7 rises, and the cutting mechanism performs the cutting.

[0040] 4. After the cutting is completed, the slide 61 continues to move a short distance, the clamping block 65 pulls the tungsten electrode rod away from the cutting mechanism, pulls it completely onto the receiving rack 7, and releases the clamping block. Then the receiving rack 7 resets. During the reset process, the tungsten electrode rod is pushed onto the placement rack.

[0041] 5. The feeding wheel 2 and the straightening wheel 4 continue to move, and the slide block 61 drives the clamping block to return to continue clamping, repeating the process.

[0042] This new type of automatic straightening, cutting, receiving, and unloading system is highly safe, reduces manual intervention, and improves work efficiency.

[0043] All aspects not detailed in this utility model are well-known to those skilled in the art. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
