Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, and more specifically to a shearing butt welding machine. Background Technology

[0002] Profiles are usually made by rolling steel strips into shape using a roller press. Since the reloading operation of the roller press is quite cumbersome, a continuous supply of steel strips is required to the roller press.

[0003] Considering that steel strips are transported in coils, once one coil is used up, another coil needs to be joined together before being fed to the rolling mill. However, the very center of the coil, at its very end, is considered scrap due to its significant curvature and generally needs to be cut before joining it to the next coil. Current technology involves manual cutting and welding, which is not only inefficient but also makes it difficult to align the cut end of the previous coil with the front end of the next coil, leading to weld problems and affecting subsequent processing. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, when cutting and welding steel strip coils, not only is the efficiency low, but it is also difficult to align the cut end of the front coil steel strip with the front end of the lower coil steel strip, resulting in unqualified welds and affecting subsequent processing.

[0005] To address the aforementioned problems, this utility model provides a shearing and welding machine, including a conveyor component arranged from front to back, and further comprising:

[0006] The shearing mechanism located at the front of the conveyor includes an upper cutting platform and a lower cutting platform arranged vertically, and a shearing drive for moving the upper cutting platform and the lower cutting platform closer to or further away from each other. The upper cutting platform and the lower cutting platform are respectively provided with an upper cutting blade and a lower cutting blade.

[0007] The welding mechanism located at the rear of the conveyor includes a welding assembly, a base plate for supporting the lower side of the workpiece, a front pressure head located above the base plate, and a rear pressure head located above the base plate. The front pressure head and the rear pressure head are driven to rise and fall by a front drive component and a rear drive component, respectively. The base plate has a slot in the middle along the left and right direction, and a liftable limiting plate is provided in the slot. When the limiting plate rises, it is higher than the workpiece, and when it falls, it is lower than the upper part of the base plate. The welding assembly is located above the base plate and includes a welding head located between the front pressure head and the rear pressure head.

[0008] The above solution utilizes a conveyor to transport workpieces such as steel strips. It also incorporates a shearing mechanism and a welding structure. The shearing mechanism automatically cuts the waste material at the end of the workpiece. The conveyor then moves the workpiece backward until its rear end is positioned between the rear pressure head and the base plate. Next, a limiting plate rises, and the conveyor moves the next workpiece forward until its front end abuts against the limiting plate. The limiting plate then descends, and the front pressure head lowers and presses against the rear of the previous workpiece. The conveyor continues to move the new workpiece forward a short distance until its front end abuts against the rear end of the previous workpiece. The pressure head then lowers and presses against the front of the next workpiece. At this point, the rear end of the previous workpiece is accurately positioned with the front end of the next workpiece, ready for welding by the welding assembly. Compared to existing technologies, this solution achieves automatic shearing of the workpiece through the shearing mechanism, accurate positioning of the workpiece in the forward / backward direction through the limiting plate of the welding structure, and accurate positioning of the workpiece in the vertical direction through the front and rear pressure heads. This ensures reliability during subsequent welding and results in higher efficiency.

[0009] In an improved embodiment, a limiting drive is provided on the lower side of the base plate. The limiting drive has an upward output end. The limiting plate is connected to the output end of the limiting drive and is driven by the limiting drive to achieve lifting and lowering, thereby realizing the lifting and lowering drive of the limiting plate through the limiting drive.

[0010] In an improved embodiment, the shearing mechanism further includes a vertical guide post, the shearing drive is connected above the guide post and has a downward output end, and the upper cutting table is slidably connected to the guide post and connected to the output end of the shearing drive, thereby realizing the lifting and lowering drive of the upper cutting table through the shearing drive.

[0011] In an improved embodiment, the upper cutting table has an upper elastic pressure plate at its front and an upper cutter at its rear. The lower cutting table has a lower elastic pressure plate at its rear and a lower cutter at its front. The upper elastic pressure plate is opposite to the lower cutter, and the lower elastic pressure plate is opposite to the upper cutter. Thus, when the upper and lower cutting tables approach each other, the upper elastic pressure plate and the lower cutter clamp the front of the steel strip, and the lower elastic pressure plate and the upper cutter clamp the rear of the workpiece. As the upper and lower cutting tables continue to approach each other, the steel strip between the upper and lower cutters can be cut.

[0012] In an improved embodiment, the conveying component includes a conveying motor and multiple conveying rollers arranged at intervals from front to back. The axis of the conveying rollers is along the left-right direction. The conveying motor acts on the conveying rollers to drive their rotation. This design is simple in structure and reliable in operation.

[0013] In an improved embodiment, the welding assembly further includes a linear guide rail disposed above the base plate in a left-right direction, and the welding head is connected to the linear guide rail and driven by the linear guide rail to move in the left-right direction.

[0014] In an improved embodiment, the opposite sides of the front and rear pressure heads are chamfered to facilitate welding operations and avoid interference. Attached Figure Description

[0026] Please see Figures 1-5 An embodiment of this utility model provides a shearing and welding machine, including a conveyor 1 arranged from front to back, and further comprising:

[0027] The shearing mechanism 2, located at the front of the conveyor 1, includes an upper cutting platform 21 and a lower cutting platform 22 arranged vertically, and a shearing drive 23 for moving the upper cutting platform 21 and the lower cutting platform 22 closer to or further away from each other. The upper cutting platform 21 and the lower cutting platform 22 are respectively provided with an upper cutting blade 24 and a lower cutting blade 25.

[0028] The welding mechanism 3, located at the rear of the conveyor 1, includes a welding assembly, a base plate 31 for supporting the lower side of the workpiece, a front pressure head 32 located above the base plate 31, and a rear pressure head 33 located above the base plate 31. The front pressure head 32 and the rear pressure head 33 are driven to rise and fall by the front drive member 321 and the rear drive member 331, respectively. The base plate 31 has a slot 311 in the middle along the left and right direction. A liftable limit plate 34 is provided in the slot 311. When the limit plate 34 rises, it is higher than the workpiece and when it falls, it is lower than the upper side of the base plate 31. The welding assembly is located above the base plate 31 and includes a welding head 35 located between the front pressure head 32 and the rear pressure head 33.

[0029] The above scheme achieves the transportation of workpieces such as steel strips through the conveyor 1. At the same time, by setting up a shearing mechanism 2 and a welding structure, the shearing mechanism 2 is used to automatically shear the waste material at the end of the workpiece. Then, the conveyor 1 drives the workpiece to continue moving backward until the rear end of the workpiece is between the rear pressure head 33 and the bottom plate 31. Then, the limiting plate 34 rises, and the conveyor 1 drives the next workpiece to move forward until the front end of the new workpiece abuts and is positioned against the limiting plate 34. Then, the limiting plate 34 falls, the front pressure head 32 falls and presses against the rear of the previous workpiece, and the conveyor 1 continues to drive the new workpiece to move forward a short distance until the front end of the new workpiece abuts against the rear end of the previous workpiece. Then, the pressure head 33 falls and presses against the front of the next workpiece. At this time, the rear end of the previous workpiece is accurately positioned with the front end of the next workpiece, and welding is performed by the welding assembly. Compared with the prior art, the above solution achieves automatic shearing of the workpiece by setting the shearing mechanism 2, accurately positions the workpiece in the front-to-back direction by the limiting plate 34 of the welding structure, and accurately positions the workpiece in the up-to-down direction by the front pressure head 32 and the rear pressure head 33, thus ensuring the reliability of subsequent welding and achieving high efficiency.

[0030] In this embodiment, a limiting drive member 341 is provided on the lower side of the base plate 31. The limiting drive member 341 has an upward output end. The limiting plate 34 is connected to the output end of the limiting drive member 341 and is driven by the limiting drive member 341 to achieve lifting and lowering, thereby realizing the lifting and lowering drive of the limiting plate 34 through the limiting drive member 341. The limiting drive member 341 is preferably a cylinder or electric cylinder with a bracket, etc., and the bracket of the limiting drive member 341 is installed on the lower side of the base plate 31. Similarly, the front drive member 321 and the rear drive member 331 are preferably cylinders or electric cylinders with brackets, etc. The front drive member 321 and the rear drive member 331 are respectively fixed to the front and rear parts above the base plate 31 by brackets. The output ends of the front drive member 321 and the rear drive member 331 are respectively connected downward to the front pressure head 32 and the rear pressure head 33.

[0031] In this embodiment, the shearing mechanism 2 further includes two vertical guide columns, which are respectively arranged vertically on the left and right sides of the conveyor 1. The shearing drive 23 is connected above the guide columns and has a downward output end. The upper cutting table 21 is slidably connected to the guide columns and connected to the output end of the shearing drive 23, thereby realizing the lifting and lowering drive of the upper cutting table 21 through the shearing drive 23. The shearing drive 23 is preferably a cylinder or electric cylinder with a bracket, and the bracket of the shearing drive 23 is installed between the upper parts of the two guide columns.

[0032] In this embodiment, the upper cutting table 21 has an upper elastic pressure plate 26 at its front and an upper cutting blade 24 at its rear. The lower cutting table 22 has a lower elastic pressure plate 27 at its rear and a lower cutting blade 25 at its front. The upper elastic pressure plate 26 is opposite to the lower cutting blade 25, and the lower elastic pressure plate 27 is opposite to the upper cutting blade 24. Both the upper elastic pressure plate 26 and the lower elastic pressure plate 27 have vertical springs, which can be compressed vertically. When the upper cutting table 21 and the lower cutting table 22 approach each other, the upper elastic pressure plate 26 and the lower cutting blade 25 clamp the front of the steel strip, and the lower elastic pressure plate 27 and the upper cutting blade 24 clamp the rear of the workpiece. As the upper cutting table 21 and the lower cutting table 22 continue to approach each other, the steel strip between the upper cutting blade 24 and the lower cutting blade 25 can be cut off.

[0033] In this embodiment, the conveying component 1 includes a conveying motor 11 and a plurality of conveying rollers 12 arranged at intervals from front to back. The axis of the conveying rollers 12 is along the left-right direction. The conveying motor 11 acts on the conveying rollers 12 to drive the rotation of the conveying rollers 12. The structure is simple and the operation is reliable. Of course, the conveying component 1 can also be any device in the prior art that can convey workpieces such as steel strips, and this design does not limit it.

[0034] In this embodiment, the welding assembly also includes a linear guide rail 351 disposed above the base plate 31 in the left-right direction. The welding head 35 is connected to the linear guide rail 351 and is driven by the linear guide rail 351 to move in the left-right direction.
