Description

Technical Field

[0001] This utility model relates to the field of automotive precision continuous stamping dies, and in particular to a waste cutting device for automotive precision continuous stamping dies. Background Technology

[0002] Automotive precision progressive stamping dies are high-precision, high-efficiency dies specifically designed for the automotive industry. They are primarily used for mass production of automotive parts, especially for high-requirement components such as car bodies, chassis, and structural parts, and are widely applied in stamping processes.

[0003] Existing technologies, such as the utility model patent with publication number CN105215150A, disclose a continuous hole punching die. This patent belongs to the field of mold equipment. The punch is installed on the upper die base, and the die is installed on the lower die base. The punch has multiple punching portions, which are spaced apart along the extension direction of the die cavity. The die has multiple through holes for the punching portions to pass through, and the multiple through holes are connected to the die cavity. The continuous hole punching die also includes a support rod and an ejection mechanism. The support rod is inserted into the die cavity, and one end of the support rod extends out of the die cavity. The end of the support rod extending out of the die cavity is detachably connected to the die. An annular channel for inserting metal tubes is formed between the support rod and the inner surface of the die. The support rod also has multiple forming holes. The ejection mechanism is installed on the lower die base and can slide relative to the die along the axis of the cavity, allowing the metal tube to slide relative to the die. When this stamping die punches multiple holes, the metal tube is not easily deformed, the hole forming quality is high, and the processing efficiency is improved.

[0004] The inventors discovered in daily use that in the existing technology, during continuous stamping, waste needs to be removed from the mold in a timely manner. If the waste cannot be cleaned up in time, it will easily accumulate in the mold, affecting the normal operation of the mold. The accumulated waste may interfere with the next stamping or cause wear on the mold. Moreover, the accumulation of waste not only affects the operation of the mold, but also makes the recycling of waste difficult. If the waste cannot be removed or recycled smoothly, it may lead to material waste and affect production efficiency and economy.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The cutting structure 5 includes two slide plates 54, which are fixedly connected to the body 3. A connecting seat 59 is provided on the side of the base 1 near the slide plate 54. Insert rods 51 are slidably connected to both sides of the connecting seat 59 and the base 1. A connecting rod 52 is fixedly connected to the end of the insert rod 51 away from the slide plate 54. Two uprights 53 are fixedly connected to the upper surface of the connecting seat 59. A groove 58 is provided on the inner wall of the upright 53. The groove 58 is slidably connected to the slide plate 54. A round rod 55 is fixedly connected to the end of the slide plate 54 away from the body 3. A cutter 57 is fixedly connected to the lower end of the round rod 55. When cutting the stamping waste is required, the movable connecting seat 59 is aligned with the base 1, and then the connecting rod 52 is pulled to move the insert rod 51. The insert rod 51 is then aligned with the base 1 and the connecting seat 59, and then inserted and fixed. When the machine body 3 presses down for stamping, the machine body 3 moves the connecting plate 66, which slides on the inner wall of the slide groove 58. The connecting plate 66 moves the round rod 55, which in turn moves the cutter 57 downwards. The cutter 57 then cuts off the stamping waste. A limit rod 56 is fixedly connected inside the slide groove 58, and the limit rod 56 is slidably connected to the slide plate 54. The limit rod 56 can limit the slide plate 54, preventing it from shifting during use and improving its service life.
