Description

Technical Field

[0001] The invention relates to the technical field of sheet metal processing equipment, in particular to a punching device for automobile sheet metal parts which is convenient for loading and unloading. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming (such as car bodies), etc. Its notable feature is that the thickness of the same part is consistent. Products processed by sheet metal technology are called sheet metal parts. Automobile sheet metal parts are widely used. Most automobile sheet metal parts need to be punched. When punching sheet metal parts, the sheet metal parts are still in the state of thin metal plates; for example, the Chinese utility model patent with authorization announcement number CN217253049U discloses a drilling device for sheet metal parts, which discloses an outer frame, a lifting plate, a lifting assembly and a clamping assembly. The lifting plate is slidably mounted on the outer frame, and a drill bit is arranged at the bottom of the lifting plate; the lifting assembly is installed between the outer frame and the lifting plate to adjust the position of the lifting plate and the drill bit; the clamping assembly is arranged at the bottom of the outer frame to fix the workpiece, but the current automobile sheet metal parts have the following defects when punching:

[0003] Since the sheet metal parts are in the state of thin metal plates when being punched, most of the loading is done by manual moving, which is rather troublesome. There are also methods of using vacuum adsorption with swing arms and other mechanisms for loading, but there are still certain defects. First, when the metal sheet-like workpiece is taken out by adsorption, there is no support at the bottom, which is easy to deform, especially for larger workpieces, affecting the quality of the sheet metal parts; second, when loading and unloading, it is necessary to wait for the processing to be completed, and then move the punched material down and put the workpiece in. At this time, the punching mechanism needs to wait for the loading and unloading time, and can only perform the punching work after the loading is completed. This takes a long time, which affects the efficiency of punching.

[0004] For this reason, we propose a punching device for automobile sheet metal parts that is convenient for loading and unloading to solve the above problems. Summary of the invention

[0051] Embodiment 3:

[0052] See also Figure 1-14 , which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When the present invention is in use, a workpiece table assembly 26 should be located at the position of the punching mechanism 5 to perform a punching operation. At this time, the material handling structure 4 performs loading and unloading operations. First, the workpiece that has been punched on another workpiece table assembly 26 is moved and placed on the unloading table 12. At the same time, the material handling structure 4 absorbs the workpiece on the loading table 11 and then transports it to the workpiece table assembly 26. When the punching operation is completed, the lower table 23 and the upper table 25 of the workbench mechanism 2 exchange positions, so that the two workpiece table assemblies 26 exchange positions, and the punching operation can be continued. At the same time, the material handling structure 4 performs loading and unloading operations again to form a cyclic punching operation. The material handling structure 4 of the present invention adsorbs the workpiece through the adsorption component 44. After completion, the transverse plate 48 moves inward, and the strip support block 49 can be used to support the column. The bottom surface of the workpiece is well supported during the movement of the workpiece, so that the bottom of the workpiece also has good support to avoid deformation of the workpiece. When the workpiece is placed on the surface of the workpiece table assembly 26, the strip support block 49 will be located between the serrated plates 262, which will not affect the normal material discharge. The punching operation of the present invention is carried out on the workbench mechanism 2, and the workbench mechanism 2 is provided with two workpiece table assemblies 26, and the two workpiece table assemblies 26 can exchange positions, so that when the workpiece on one of the workpiece table assemblies 26 is undergoing punching processing, the other workpiece table assembly 26 is in an idle state. At this time, the processed workpiece on the workpiece table assembly 26 can be moved, and a new workpiece can be placed to complete the loading and unloading operations. After the punching is completed, the two workpiece table assemblies 26 exchange positions, and the punching operation can be carried out continuously without waiting for the loading and unloading time, making the punching operation smoother and more efficient.
