Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal processing, and in particular relates to a flattening device for cutting sheet metal parts. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. Due to its small thickness, sheet metal parts may bend during transportation, storage and handling. Therefore, before forming them, the sheet metal parts need to be flattened in advance to ensure the accuracy and quality of subsequent processing.

[0003] The prior art discloses a sheet metal flattening device for sheet metal cutting with a publication number of CN218799897U, comprising a base, a limit table for flattening the sheet metal fixedly mounted on the top of the base, a sheet metal disposed in a groove at the top of the limit table, a support frame fixedly mounted on the top of the base, and a bearing block fixedly mounted on the bottom end of the piston rod of the electric hydraulic cylinder. The utility model has a novel structure, has an integrated function of flattening the sheet metal and assisting in cutting and fixing, avoids multiple installation and disassembly of the sheet metal, improves the flattening and cutting efficiency, and is suitable for promotion.

[0004] However, there are still some deficiencies in the above-mentioned prior art: in the prior art, flattening and laser cutting are combined to form an integrated function, so that the sheet metal parts can be placed on a limit table for both flattening and laser cutting, thereby eliminating the need to carry the sheet metal parts and avoiding multiple installation and disassembly of the sheet metal parts. However, in real life, when sheet metal parts are cut by a laser cutting machine, since laser cutting uses a high-temperature laser beam and high-pressure gas to melt and blow off the sheet metal parts to achieve the cutting of the workpiece, slag will be generated during the laser cutting process, which is not suitable for real life. There is usually a hollow storage groove below the plane where the plate to be laser cut is placed. Therefore, in the above-mentioned prior art, after the sheet metal is flattened on the limit table and then laser cut, slag will fall on the top surface of the limit table. If it is not cleaned in time, it will stick to the top surface of the limit table and be difficult to clean. It will also make the top surface of the limit table uneven, so that the flattening of the next sheet metal will be greatly affected, greatly reducing the flattening quality of the sheet metal, and then affecting the subsequent laser cutting. In addition, the penetration of laser cutting is relatively strong, which may also cause damage to the top surface of the limit table. Further improvement is needed in this regard. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a flattening device for sheet metal cutting, so that the device can perform flattening processing on the sheet metal and also perform laser cutting processing, and the flattening processing and laser cutting processing can be switched arbitrarily without affecting each other, and it is convenient to uniformly clean up the slag or waste generated by the laser cutting.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flattening device for sheet metal cutting, comprising a workbench, a through slot is provided in the workbench, a rectangular slot communicating with the through slot is provided on the top surface of the workbench, two brackets are arranged on the top surface of the workbench, and also comprises: an L-shaped support table, rotatably arranged on the top surface of the workbench; a punching block, arranged on the bottom surface of the L-shaped support table and capable of vertical height adjustment; a laser gun head, arranged between the two brackets and capable of horizontal movement and height adjustment; a moving seat, horizontally moving in the through slot and in sliding contact with the upper and lower bottom surfaces of the through slot; a containing slot, arranged on one side of the moving seat; a plurality of limit strips, arranged on the upper end of the containing slot; and a plurality of conical blocks, arranged on the top surface of the limit strip.

[0010] Optionally, the movable seat is located directly below the rectangular groove and is wider than the rectangular groove.

[0011] Optionally, a notch communicating with the through slot is formed on the top surface of the workbench near the accommodating slot.

[0012] Optionally, the upper end of the conical block is a plane, and the plane is in the same plane as the top surface of the movable seat.

[0013] In summary, this application has the following beneficial effects:

[0014] The present application provides a stamping block with a rotatable position and height adjustment on the top surface of the workbench, which cooperates with a laser gun head that can be horizontally moved and adjusted in height, so that the device can integrate the flattening and cutting functions of sheet metal parts, eliminating the need for multiple transportation and fixation of workpieces, thereby improving the flattening and cutting processing efficiency, reducing the labor intensity of staff, and being more practical.

[0015] In the present application, a receiving groove, a waste collection box, a limiting strip, and a conical block are provided on one side of the movable seat. Through the cooperation of the receiving groove, the waste collection box, the limiting strip, the conical block and the rectangular groove, the sheet metal parts can be laser cut and the slag and waste generated during the laser cutting can be uniformly collected for easy cleaning. The top surface of the solid part on the other side of the movable seat cooperates with the rectangular groove to flatten the sheet metal parts, and then the flattening and cutting can be quickly switched between each other by adjusting the cooperation between the different positions of the movable seat and the rectangular groove, without affecting each other. Moreover, through the cooperation of the side plate and the telescopic rod, there is no need for the staff to carry the sheet metal parts and clamp and fix them multiple times, which reduces the labor intensity of the staff, improves the processing efficiency of the workpiece flattening and cutting, and the design is more reasonable and more practical.
