Description

Technical Field

[0001] The utility model relates to the technical field of monitoring cameras, in particular to a monitoring camera lens base mold block. Background Art

[0002] The housing of an existing surveillance camera is usually a thin plate with a convex bump on the plate to enhance the structural strength of the plate. The existing process usually adopts a top-down stamping method, that is, a support is set on the lower die, and the plate is formed by the pressure of the upper die.

[0003] In the patent with the authorization announcement number CN206492849U, a surveillance camera lens base mold block is disclosed. During stamping, the downward pressure of the pressing block is converted into a convex head to apply upward pressure on the sheet from the bottom to the top under the sheet, forming a convex bulge from the bottom to the top on the sheet, and the sheet does not need to be turned over in the subsequent process. In addition, the downward pressing wedge block is used to push the guide wedge block, and then the guide wedge block is used to push the upper wedge block to press the sheet upward. This pressure is less than the downward pressure of the punching machine on the upper die, avoiding damage to the sheet.

[0004] The above-mentioned prior art solutions have the following defects: although the above-mentioned patent achieves the elimination of the need to flip the sheet and reduce sheet damage in subsequent processes, the method of using the downward pressure wedge block to push the guide wedge block, and then using the guide wedge block to push the upper wedge block to press the sheet upward, is likely to accelerate the wear of the mold, and the punch directly punches the sheet, the sheet will be subjected to the pressure and impact force of the punch, which will lead to a decrease in processing accuracy. For this reason, a surveillance camera lens base mold block is proposed. Utility Model Content

A pressure plate 10 is arranged above the top plate 3 inside the through groove 9, and a pre-pressing assembly is arranged on the pressure plate 10; the pressure column 14 is pushed to move inside the connecting groove 13 by the fixing plate 15. When the pressure plate 10 abuts against the top of the top plate 3, the contact area of ​​the downward pressure is increased, and the stability of the stamping is improved. The pressure plate 10 continues to move downward, and the convex head 8 moves out of the through groove 9. The convex head 8 applies an upward force to the sheet material from bottom to top, thereby completing the stamping of the sheet material. By setting the sheet material abutting against the punch, the stamping accuracy can be improved, and the wear of the punch and the die can be reduced. At the same time, there is no need to flip the sheet material during subsequent processes.

During this process, the fixed plate 15 pushes the pressing column 14 to move inside the connecting groove 13. When the pressing plate 10 contacts the top of the top plate 3, the downward pressure is increased. The contact area improves the stability of stamping. At this time, the fixed plate 15 moves to the inside of the second guide groove 12, and the pressing plate 10 continues to move downward. The pressing plate 10 drives the top plate 3 to move on the outside of the sliding column 2, and the convex head 8 moves out of the through groove 9. The convex head 8 applies an upward force to the sheet from bottom to top, thereby completing the stamping of the sheet. At the same time, there is no need to turn the sheet over in subsequent processes; the first telescopic spring 7 and the second telescopic spring 16 can drive the top plate 3 and the pressure column 14 to reset, so as to facilitate the next processing of the sheet.
