Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a punching device for cold-rolled thin plate processing. Background Art

[0002] Both metal rolled products and cold-rolled metal plates are metal plates processed by cold rolling. The difference is that rolled products focus on the thickness of the plate, while cold-rolled plates focus on the strength of the material. The existing patent (Announcement No.: CN219581750U) discloses a drilling device for ferrous metal smelting rolled products. The utility model sets a first arc groove and a second arc groove to abut against the outer wall of the metal rolled product. The protective box can try to avoid the metal scraps from splashing during the drilling process of the metal rolled product and polluting the working environment. The metal scraps are collected by the collection box for easy cleaning. However, in actual applications, it is often necessary to punch holes in the rolled products continuously. In the above technical solution, the rolled products cannot move forward and backward after clamping, which is inconvenient for continuous punching. As a result, the actual processing needs to rely on manual movement of the rolled products to adjust the punching position, which is time-consuming and labor-intensive, and is not conducive to actual processing. To this end, we propose a punching device for cold-rolled thin plate processing. Utility Model Content

[0021] The collection box 2 is connected to a cleaning mechanism 7;

The negative pressure created by the air pump 72 is used to make the dust hood 74 absorb the debris in the collection box 2, and enter the material collection box 71 through the universal tube, and then fall into the material collection drawer 73. When cleaning is needed, just pull out the material collection drawer 73 and pour out the debris therein.

[0024] Furthermore, the dust hoods 74 are respectively located at both ends of the material collecting box 2 to prevent the cold-rolled plate from being affected in its movement;

[0025] Specifically, by setting up a lifting mechanism, a protective box 6, a collection box 2 and a cleaning mechanism, the part of the cold-rolled plate that needs to be punched is placed in the collection box 2, and the lifting mechanism is used to drive the protective box 6 to move up and down.

By rotating the screw 95, the screw 95 can drive the pressing plate 93 to move up and down along the limiting rod 94, thereby pressing the cold-rolled plate tightly against the support plate 71, so as to stably clamp the cold-rolled plate, and multiple cold-rolled plates can be clamped at the same time, so as to perform punching operations on multiple cold-rolled plates at one time, thereby improving processing efficiency;

[0028] Furthermore, a sliding block 11 is fixed at the bottom of the support plate 91, and a sliding groove 12 is provided on the bottom plate 1 to cooperate with the sliding block 11; in cooperation with the cylinder 2 8, the support plate 91 can move stably on the bottom plate 1;

[0029] Furthermore, both ends of the mounting frame 92 are provided with limit plates 14 fixed on the bottom plate 1, and the limit plates 14 limit the two sides of the cold-rolled plate. The outer side of the limit plate 14 is provided with a scale plate 10 parallel to the length direction of the bottom plate 1, and the scale plate 10 is fixed on the bottom plate 1.
