Description

Technical Field

[0001] The utility model relates to the technical field of die side cutting, in particular to a metal stamping die side cutting device. Background Art

[0002] Metal stamping die side cutting refers to the use of a special side cutting device to cut the side of a metal sheet or strip during the metal stamping process. This side cutting operation is intended to remove the chips generated during the stamping process, thereby preventing the chips from overlapping with the product and causing damage to the product. It also protects the integrity of the die. It is an important stamping processing technology and is of great significance for improving product quality, protecting dies and improving production efficiency.

[0003] After searching, the Chinese patent with publication number CN219025645U discloses a side cutting device with cooling for a metal stamping die. In actual use, the lack of a cooling device can easily lead to excessive temperature of the metal workpiece during the side cutting operation, causing deformation of the metal workpiece and affecting product quality. At the same time, after the stamping is completed, manual demolding is required, which is labor-intensive and has low demolding efficiency. Therefore, the upper die is separated from the lower die by controlling the cylinder. At this time, the spring loses its restriction, and with the cooperation of its own elastic force, the push block and the push rod can push the stamped metal workpiece out of the lower die, which can reduce the workload of the staff and improve the demolding efficiency.

[0004] There are still some shortcomings in the use of the above-mentioned stamping die side cutting device. When the die is side cut, the direction of the cutter is usually fixed, which makes it inconvenient to flexibly adjust the rotation angle of the cutter during side cutting according to the needs of side cutting, thereby easily reducing the effect and accuracy of side cutting. If the angle does not fit the workpiece, it is easy to cause incomplete side cutting and uneven cutting surface, which reduces the adjustability of side cutting and is inconvenient to use.

[0032] As attached Figure 5 As shown, both front and rear ends of the bottom plate 1 are fixedly connected with a material receiving box 16, and a motor 17 is fixedly installed on the right side of the bottom end of the front material receiving box 16. The rear side of the bottom end of the bottom plate 1 is rotatably connected with two synchronous wheels 18, and a synchronous belt 19 is arranged on the outer side of the two synchronous wheels 18. A screw rod 20 is fixedly connected to the front end of the synchronous wheel 18, and the other end of the right end screw rod 20 is fixedly connected to the output end of the motor 17, so that after the motor 17 is turned on, the motor 17 drives the right side screw rod 20 to rotate, and under the action of the synchronous wheel 18 and the synchronous belt 19, it is convenient to drive the left side screw rod 20 to rotate, without using multiple motors 17, thereby reducing the usage of the motor 17.

[0033] As attached Figure 1-2As shown, a scraper 21 is threadedly connected to the middle part of the screw rod 20, and a cleaning brush 22 is fixedly connected to the front and rear sides of the scraper 21.
