Technical Field
[0001] The invention relates to the field of sheet metal processing, and in particular to a sheet metal processing punching device. Background Art
[0002] Sheet metal processing is a key technology that sheet metal technicians need to master, and it is also an important process for the formation of sheet metal products. Sheet metal processing includes traditional cutting, blanking, bending and pressing methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, and new stamping technologies and new processes. The processing of metal sheet parts is called sheet metal processing. For example, sheets are used to make chimneys, iron barrels, oil tanks, oil bottles, ventilation ducts, elbows, round heads, funnel shapes, etc. The main processes include shearing, bending and buckling, bending, welding, riveting, etc., which require certain geometric knowledge. Sheet metal parts are thin plate hardware, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is a part whose thickness remains unchanged during the processing process. Corresponding are castings, forgings, machined parts, etc.; In the punching process of sheet metal processing, a punching device is needed to punch the material with a punch drill. However, the existing punching assembly has a simple structure and does not have a buffer assembly, which may cause damage to the punch drill and other equipment due to the impact force during the punching operation.

[0005] By adopting the above technical solution, during operation, the operator places the sheet metal on the upper surface of the workbench, and then the operator turns on the pushing assembly, and cooperates to push the moving block and other components at the bottom of the moving block horizontally left and right to above a suitable working area, and then the operator turns on the driving cylinder, and cooperates with the output end to drive the driving plate to move downward, and completes the punching operation of the sheet metal through the punching assembly arranged at the bottom of the connecting plate. During the punching operation, the punching assembly contacts the sheet metal and generates pressure. At this time, the connecting plate above the punching assembly squeezes the driving plate upward. At this time, the driving plate is subjected to pressure and cooperates to squeeze the buffer frame downward. The buffer frame squeezes the buffer plate in the buffer cylinder downward, and the damping rod at the bottom of the buffer plate cooperates with the buffer spring to support and buffer the operation, thereby avoiding huge impact force from damaging the punching assembly or other equipment.

[0010] Further configuration: a plurality of through holes arranged at intervals are provided on the upper surface of the workbench below the punching drill bit.
[0011] By adopting the above technical solution, during operation, the punching drill cooperates with the downward punching operation, and the multiple through holes opened on the workbench can prevent the punching drill from directly contacting the workbench, thereby avoiding damage to the punching drill, and the waste after punching falls directly from the through holes for easy collection.
[0012] Further configuration: a material receiving box with an opening upward is placed on the upper surface of the base below the workbench.
[0013] By adopting the above technical solution, the waste generated by the punching operation falls directly from the through holes on the workbench and directly falls into the receiving box, which is convenient for the operator to handle in a unified and centralized manner.
[0014] Further configuration: ventilation holes are provided on the support plates at both sides of the workbench, and ventilation fans are installed in the ventilation holes.
[0015] By adopting the above technical solution, a certain amount of smoke will be generated during the punching operation, and the smoke will be sucked and discharged through the cooperation between the ventilation fans.
[0016] In summary, the present invention has the following beneficial effects: The present invention is equipped with a buffer component. During operation, the operator turns on the driving cylinder and cooperates with the output end to drive the driving plate to move downward, and completes the punching operation of the sheet metal through the punching component arranged at the bottom of the connecting plate. During the punching operation, the punching component contacts the sheet metal and generates pressure. At this time, the connecting plate above the punching component squeezes the driving plate upward. At this time, the driving plate is subjected to pressure and cooperates to squeeze the buffer frame downward. The buffer frame squeezes the buffer plate in the buffer cylinder downward. The damping rod at the bottom of the buffer plate cooperates with the buffer spring to support and buffer the operation, thereby avoiding damage to the punching component or other equipment by a huge impact force, and improving the safety and stability of the entire punching operation.
[0017] The present invention is equipped with a punching assembly. During the punching operation, the operator installs a punching drill bit of a corresponding size in the corresponding clamping seat. At this time, the operator turns on the servo motor to drive the rotating shaft and the mounting block on the rotating shaft to rotate, so as to achieve rapid conversion, until the punching drill bit of a corresponding size on the mounting block is rotated vertically downward, and cooperates with other components to complete the punching operation.
