Description

Technical Field

[0001] This invention relates to the field of strip steel processing technology, specifically to an automatic strip steel shearing and welding machine. Background Technology

[0002] Automatic strip shearing and welding machines are core connecting equipment in the metal processing and strip steel production fields. Their core function is to achieve automatic shearing, precise butt jointing and welding of the tail end of the previous strip and the head end of the next strip during strip steel production or processing.

[0003] The existing automatic strip shearing and welding machine mainly works by conveying the tail of the front strip and the head of the rear strip to the shearing station when the front strip is about to run out. The shearing unit cuts off the irregular parts of the head and tail of the strip, the docking mechanism drives the two strips to be precisely aligned, the welding system completes the butt welding, the inspection component verifies the weld quality, and after passing the inspection, the strip continues to be conveyed, realizing continuous production.

[0004] However, the above-mentioned equipment has certain shortcomings in use. Most of the existing equipment is designed in sections, with strip steel conveying, shearing and welding processes operating independently without an integrated collaborative structure.

[0016] Compared with the prior art, the present invention provides an automatic strip shearing and welding machine, which has the following advantages: 1. This automatic strip shearing and welding machine is designed to meet the automated processing requirements of continuous strip production. It includes a welding assembly that, in conjunction with a bidirectional threaded rod, drives the drive module. A servo motor drives the chain and rubber wheels via a sprocket module. Combined with the limit rod and limit cylinder of the limit module, this ensures smooth strip transport. Rollers on the support frame assist in strip movement. The shearing hydraulic equipment of the shearing module drives the oblique and flat shearing blades to quickly cut the strip. A collection box centrally collects shearing waste, preventing waste accumulation from affecting processing. The welding box provides a closed and stable working space for strip butt welding.

[0017] 2. To adapt this automatic strip shearing and welding machine to high-precision strip processing scenarios, a clamping component is installed. This component, in conjunction with the clamping hydraulic equipment, pushes the slide to drive the pressing roller to clamp the strip behind the shearing module, preventing the strip from warping during shearing. The spring rod in the welding box pushes the pressing frame to drive the rubber roller to elastically clamp the strip joint. In conjunction with the round roller on the hinge frame, this ensures that the strip fits tightly during welding while avoiding rigid compression that could damage the strip surface.

[0018] 3. To adapt to the high stability requirements of automated continuous strip processing, this automatic strip shearing and welding machine is equipped with a centering component. This component, in conjunction with the helical spring inside the square tube, pushes the slide rod to drive the centering wheel on the connecting frame. Multiple sets of centering wheels are symmetrically distributed, automatically correcting the offset strip to the center position. The support roller frame fits against the surface of the centering wheel to enhance the structural stability of the centering wheel. The reinforcing plate strengthens the connection between the square tube and the support frame to prevent the component from shaking during the centering process. The centering component completes the position correction before the strip enters the shearing and welding area. In conjunction with the conveying of the drive module and the fixing of the clamping component, the strip is kept in a centered state at all times. Attached Figure Description

[0023] Please see Figures 1-12 The present invention provides a technical solution: An automatic strip shearing and welding machine includes a support frame 1, and an mounting frame 2 is provided on the outside of the support frame 1.

[0024] In one embodiment of the present invention, a welding machine assembly 3 is provided on the support frame 1 and the mounting frame 2. The welding machine assembly 3 includes a frame 31, which is fixedly mounted on the mounting frame 2. A bidirectional threaded rod 32 is provided on the frame 31, and a drive module 33 is threadedly mounted on the bidirectional threaded rod 32. A limit module 34 is provided between the drive module 33 and the mounting frame 2. A bracket 35 is fixedly mounted on the support frame 1, and a roller 36 is rotatably mounted on the bracket 35. A shearing module is provided on the bracket 35, and the bottom of the bracket 35 is fixed. A collection box 311 is fixedly installed, a welding box 312 is fixedly installed on a bracket 35, the welding box 312 has a material inlet / outlet 313, a maintenance plate 314 is snapped onto the welding box 312, a wheel is fixedly installed on a bidirectional threaded rod 32, the drive module 33 includes a moving plate 331, the moving plate 331 is threaded onto the bidirectional threaded rod 32, multiple sets of sprocket modules 332 are provided on the moving plate 331, a servo motor 333 is fixedly installed on the moving plate 331, and a servo motor 333 is fixedly installed on the moving plate 331. A support plate 334 is provided. Multiple sets of chains 335 are mounted on multiple sprocket modules 332, and rubber wheels 336 are fixedly installed on the chains 335. The sprocket module 332 is connected to the output end of the servo motor 333. The limit module 34 includes a limit rod 341, which is fixedly installed on the mounting frame 2. A limit cylinder 342 is fixedly installed on the moving plate 331 and slides on the limit rod 341. The frame 31, the bidirectional threaded rod 32, the drive module 33, and the limit module 34 are provided with… Multiple shearing modules are provided, including a flat shearing blade 37, which is fixedly mounted on a bracket 35. A frame-shaped frame 38 is fixedly mounted on the bracket 35, and a shearing hydraulic device 39 is fixedly mounted on the frame-shaped frame 38. An oblique shearing blade 310 is fixedly mounted on the piston end of the shearing hydraulic device 39. Multiple sets of brackets 35, rollers 36, flat shearing blades 37, frame-shaped frames 38, shearing hydraulic devices 39, oblique shearing blades 310, and collection boxes 311 are provided. The collection boxes 311 are located directly below the shearing module.

[0025] In this embodiment, before operation, the rotating wheel on the bidirectional threaded rod 32 is rotated, causing the moving plate 331 to slide along the bidirectional threaded rod 32. The matching width between the drive module 33 and the strip steel is adjusted, and the limiting cylinder 342 slides synchronously along the limiting rod 341 to ensure that the moving plate 331 moves smoothly without deviation. The servo motor 333 is started, driving the sprocket module 332 to rotate, which in turn drives the rubber wheel 336 to rotate through the chain 335, conveying the strip steel forward along the roller 36 on the bracket 35. When the strip steel is conveyed to the shearing module position, the shearing on the frame 38 is started. The hydraulic cutting device 39 has a piston end that pushes the oblique shearing blade 310 downwards, which cooperates with the flat shearing blade 37 on the bracket 35 to quickly cut the strip steel. The waste generated by shearing falls into the collection box 311 below for centralized collection, avoiding the accumulation of waste that will affect subsequent processing. The cut strip steel enters the welding box 312 through the material inlet and outlet 313. The welding box 312 provides a closed and stable working space for butt welding of the strip steel, ensuring the welding quality. During later maintenance, the snap-fit ​​inspection plate 314 can be opened to clean and inspect the inside of the welding box 312.

[0026] In one embodiment of the present invention, a clamping assembly 4 is provided on the support frame 1. The clamping assembly 4 includes an arched frame 41, which is fixedly installed on the bracket 35. A clamping hydraulic device 42 is fixedly installed on the arched frame 41. A slide 43 is fixedly installed on the piston end of the clamping hydraulic device 42. A pressing roller 44 is fixedly installed on the slide 43. A hinged frame 45 is fixedly installed on the welding box 312. A circular roller 46 is hingedly installed on the hinged frame 45. One end of a spring rod 47 is fixedly installed on the welding box 312, and the other end of the spring rod 47 is fixedly installed on the welding box 312. A pressing frame 48 is fixedly installed, and a rubber roller 49 is rotatably mounted on the pressing frame 48. There are multiple sets of arched frame 41, pressing hydraulic device 42, slide 43, pressing roller 44, hinge frame 45, circular roller 46, spring rod 47, pressing frame 48 and rubber roller 49. The spring rod 47, pressing frame 48 and rubber roller 49 are set above the hinge frame 45 and circular roller 46. The circular roller 46 is at the same horizontal height as the material inlet and outlet 313. The arched frame 41, pressing hydraulic device 42, slide 43 and pressing roller 44 are set behind the shearing module.

[0027] In this embodiment, before the strip enters the shearing module, the clamping hydraulic device 42 on the arched frame 41 is activated. Its piston end pushes the slide 43 to drive the pressing roller 44 to move downward. The pressing roller 44 is in contact with the surface of the strip and rotates synchronously with the strip conveying, clamping the strip behind the shearing module to prevent the strip from warping due to force during shearing and to ensure that the sheared end face is flat. After the strip enters the welding box 312, it is first guided by the round roller 46 on the hinge frame 45. Then, the spring rod 47 pushes the pressing frame 48 to drive the rubber roller 49 to press the strip joint downward elastically, so that the two ends of the strip are tightly attached, which not only ensures the welding quality, but also avoids rigid extrusion damage to the strip surface. The rubber roller 49 rotates synchronously with the strip and does not affect the strip conveying efficiency.

[0028] In one embodiment of the present invention, a centering component 5 is provided on the bracket 35. The centering component 5 includes a square tube 51, which is fixedly installed on the bracket 35. A reinforcing plate 52 is fixedly installed between the square tube 51 and the bracket 35. A helical spring 53 is fixedly installed on the square tube 51. A sliding rod 54 is fixedly installed on the helical spring 53. A connecting frame 55 is fixedly installed on the sliding rod 54.

The roller support frame 57 is attached to the surface of the centering wheel 56.

[0029] In this embodiment, before the strip enters the shearing and welding area, it first contacts multiple symmetrically distributed centering wheels 56. If the strip deviates, it will squeeze one of the centering wheels 56. The centering wheel 56 pushes the slide rod 54 along the square tube 51 through the connecting frame 55, compressing the internal helical spring 53. The helical spring 53 generates a reverse elastic force, pushing the slide rod 54 and the centering wheel 56 to reset, correcting the deviated strip to the center position. The support roller frame 57 fits against the surface of the centering wheel 56, enhancing the structural stability of the centering wheel 56 when it rotates. The reinforcing plate 52 strengthens the connection between the square tube 51 and the bracket 35, preventing the components from shaking due to force during the centering process and ensuring centering accuracy.
