Description

Technical Field

[0001] The invention relates to the technical field of sheet metal plate shearing, in particular to a plate shearing device for sheet metal processing. Background Art

[0002] Sheet metal is a processing technology. There is no complete definition of sheet metal yet. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is consistent. Sheet metal has the characteristics of light weight, high strength, conductivity, low cost, good performance in large-scale mass production, etc. It has been widely used in electronic appliances, communications, automotive industry, medical equipment and other fields. For example, in computer cases, mobile phones, and MP3s, sheet metal is an indispensable component. With the increasing application of sheet metal, The design of sheet metal parts has become a very important part of the product development process. Mechanical engineers must be proficient in the design skills of sheet metal parts so that the designed sheet metal can meet the requirements of product function and appearance, and make the stamping die manufacturing simple and low-cost. Sheet metal processing is a key technology that sheet metal technical personnel need to master, and it is also an important process for the forming of sheet metal products. Sheet metal processing includes traditional cutting, blanking, bending and pressing methods and process parameters, various cold stamping die structures and process parameters, various equipment working principles and operation methods, and new stamping technology and new processes. The processing of metal sheets for parts is called sheet metal processing.

[0003] For example, the patent document with the announcement number CN 216398220 U discloses an easy-to-operate shearing device for sheet metal processing, including a box, a movable door is movably installed on the outer side of the box, a liquid crystal display controller is fixedly installed on the rear side of the top outer side of the box, a rear baffle is fixedly opened on the inner side wall of the top of the box, extension motors are fixedly installed on both sides of the rear baffle, the output ends of the two extension motors are fixedly connected with screws, a splint is movably sleeved on the rod of the screw, a front baffle is fixedly opened on the outer side wall of the top of the box, the other end of the screw is movably sleeved on the front baffle, a cutting blade is arranged at the front position of the top of the box, the cutting blade passes through the box, and a tempered glass isolation board is arranged at the front position of the top of the box. The use of this equipment to achieve semi-automatic processing of sheet metal ensures the safety of personnel while not requiring tedious maintenance in the later stage, reducing the cost of use and being more economical.

[0004] However, in the process of shearing the plates for sheet metal processing, this structure can often easily perform stamping and shearing operations on thinner sheet metal plates. However, once the sheet metal plate reaches a certain thickness, due to the limitation of the equipment's own structure, it is often only possible to continuously increase the punching force for shearing the sheet metal plate, which will cause the overall stress on the plate to be too large, and it is very easy to cause a small range of deformation problems on both sides of the shearing position of the sheet metal plate. In severe cases, it may even cause a concave position in the sheet metal plate, which needs to be re-trimped later, resulting in a low equipment yield and a high risk of rework. At the same time, the equipment cannot perform the waste cleaning operation during the sheet metal plate shearing process, and the sheet metal plate that has finally been sheared cannot be efficiently cleaned of surface impurities, and cannot meet daily use needs. Therefore, it is urgent to design a sheet metal shearing device for sheet metal processing to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a plate shearing device for sheet metal processing to solve the problem proposed in the above background technology that in the existing structure during the plate shearing process for sheet metal processing, thinner sheet metal plates can often be easily punched and sheared, but once the sheet metal plate reaches a certain thickness, due to the limitation of the device's own structure, the punching force for shearing the sheet metal plate can only be continuously increased, which will cause the overall stress on the plate to be too large, and it is very easy to cause a small range of deformation of the sheet metal plate on both sides of the shearing position, and even cause the sheet metal plate to have a concave position, and the subsequent trimming operation needs to be carried out again, resulting in a low equipment yield and a high risk of rework. At the same time, the equipment cannot perform the waste cleaning operation during the sheet metal plate shearing process, and the sheet metal plate that has finally been sheared cannot obtain an efficient cleaning operation of surface impurities, and cannot meet the daily use needs.

[0018] The plate shearing device for sheet metal processing further improves the overall use effect of the equipment by arranging a connecting frame, a chip suction frame, a drying frame, a cleaning frame, a plate discharge slot, a conveying frame, a conveyor belt, a driving motor, a one-way movable shaft, an adsorption frame, a vacuum adsorption plate, an air uniforming frame, an electric heating resistance wire, a fan frame, an inlet fan, a pumping frame, a dust filter element, an adsorption fan, a side grille, an air guide cover, a cleaning frame and a dust suction grille. In daily use, when the sheet metal plate sheared inside the processing frame can be pushed into the inside of the connecting frame, and then the adsorption fan on the top of the chip suction frame is started at this time, the surface debris can be quickly sucked out from the dust suction grille of the cleaning frame inside the connecting frame, and concentratedly blown into the inside of the pumping frame inside the chip suction frame, and blocked and collected by the dust filter element, and finally uniformly extracted. In addition, through the cooperation of the side grilles and the air guide cover on both sides of the connecting frame, synchronous air suction operations can be performed at the two ends of the processing frame, and the flying chips generated by the cutting blade cutting the blind groove can be properly and synchronously sucked and collected, and the completion can be completed at the same time. After the initial surface flying chips are extracted, the plate can be moved into the interior of the drying rack again and fall on the adsorption rack connected to the side of the conveyor belt through a one-way movable shaft. At this time, the vacuum adsorption plate is started to perform vacuum adsorption operation on the sheet metal material, and then the driving motor at one end of the reciprocating screw is started to drive the conveyor belt and the adsorption rack to rotate and adjust the whole, and the plate is sent into the cleaning rack. The cleaning operation is performed inside the cleaning rack to clean the debris adhered to the surface, and then the plate is rotated back to the interior of the drying rack along the conveyor belt. At this time, the plate entering the drying rack can be subjected to the cooperation of the fan on the surface of the fan rack and the uniform wind rack and electric heating resistance wire on the top of the conveyor belt to perform uniform and stable hot air flow drying treatment operation. At this time, the plate is inverted and adsorbed under the adsorption rack. Finally, the vacuum adsorption plate needs to be closed to make the plate fall on the adsorption rack of the next layer.
