Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a stamping die for automobile stamping parts. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. The materials used to make stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low-melting-point alloy, aluminum bronze, polymer materials, etc.

[0003] The existing stamping dies for automobile stamping parts are separated after stamping, and the operator manually removes the plate. Since the lower die is attached to the plate, it is difficult to directly remove the stamped plate. If the operator directly touches the side wall of the plate with his hands, it is easy to scratch his hands.

[0004] Therefore, a stamping die for automobile stamping parts is designed to solve the technical problem in the prior art that the sheet material after stamping is fitted with the lower die and is difficult to be removed. Utility Model Content

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0055] The existing stamping dies for automobile stamping parts are separated after stamping, and the operator manually removes the plate. Since the lower die is attached to the plate, it is difficult to directly remove the stamped plate. If the operator directly touches the side wall of the plate with his hands, it is easy to scratch his hands.

[0056] In order to solve the above technical problems, in at least one embodiment, a stamping die for automobile stamping parts is provided, comprising: an upper die 11 and a lower die 12 arranged vertically; wherein a moving mechanism 2 is arranged below the lower die 12, suitable for moving the stamped sheet to a pickup station; and a lifting mechanism 5, arranged on one side of the lower die 12 and connected to the moving mechanism 2, suitable for lifting one end of the stamped sheet to form a pickup gap between the upper end surface of the lower die 12;

[0057] By providing a moving mechanism, it is suitable for moving the plate after stamping to the retrieval station to stay away from the upper die, thereby improving the safety of the operator taking out the formed plate and placing the plate for processing. At the same time, by providing a lifting mechanism, when the processed plate is moved to the bending station, one end of the plate is lifted to form a retrieval gap, so that the operator can directly grab the upper and lower end surfaces of the plate to retrieve the parts. For the upper and lower molds, an alloy layer is formed on the surface of both by high temperature, which has a wear-resistant effect.

[0058] In some embodiments, Figure 1 As shown, the base 30 is located at the pickup station, and the position of this pickup station can be adjusted by the operator. The plate to be stamped is placed on the upper end surface of the lower mold 12, and the motor 20 is started. The output end drives the connected wheel 21 to rotate, and the other wheel 21 is driven to rotate by the belt 22. The base 30 is fixed to the belt 22. Then, driven by the belt 22, the base 30 follows the movement until it moves to the bottom of the upper mold 11. By fixing two sliding rods 23 on the inner wall of the protective shell 6, the two sliding rods 23 are respectively arranged on both sides of the base 30 and penetrate the base 30. Then, the base 30 is slidably connected with the sliding rod 23 under the drive of the belt 22 to avoid displacement during movement.

[0059] In some embodiments, in order to further limit the moving direction of the base 30, a limit groove 24 is opened on the inner bottom surface of the protective shell 6, and a limit block 25 is fixed on the end surface of the moving block 33 fixed on the lower end surface of the base 30. The limit block 25 is slidably connected with the limit groove 24 to control the moving direction of the base 30 to avoid deviation in movement that causes the upper and lower molds to be unable to align.

[0060] In some embodiments, a cylinder 1 is provided on the top surface of the inner wall of the protective shell 6, and its output end is connected to the upper mold 11. When the lower mold 12 moves into place, the cylinder 1 is started to drive the upper mold 11 to move downward and fit with the upper mold 12 to stamp the plate to be processed.

[0061] In some embodiments, Figures 2 to 3 As shown, after the stamping is completed, the motor 20 is started to reverse, so that the base 30 moves and resets. At this time, for the moving block 33, a rotating drum 331 is connected to the bearing on the side facing the pickup station, and the end of the threaded shaft 333 connected to the protective shell 6 is fixed. Then, when the center of the rotating drum 331 contacts and engages with the threaded shaft 333, the rotating drum 331 rotates, driving the connecting rod 34 connected to the bearing on its outer wall to rotate, and then the rotating plate 31 connected to the bearing at the other end of the connecting rod 34 is driven by the connecting rod 34 to rotate around the rotating shaft 40 until the rotating block 31 rotates to a horizontal state, so that the operator can remove the stamped plate from the side of the rotating block 31.

[0062] In some embodiments, a through passage is opened inside the moving block 33 , and the diameter of the through passage is larger than the diameter of the through hole 332 on the rotating cylinder 331 , so as to accommodate the threaded shaft 333 passing through the through hole 332 .

[0063] In some embodiments, the rotating shaft 40 is fixed to the rotating plate 31, and a bearing is provided at the connection between the rotating shaft 40 and the base 30. When the connecting rod 34 drives the rotating plate 31 to rotate, the rotating shaft 40 rotates synchronously to drive the driving gear 41 fixed at one end of the rotating shaft 40 to rotate. The driven gear 51 is connected to the driving gear 41 through the rack 50. At this time, the rotation direction of the driven gear 51 is consistent with that of the driving gear 41. As for the lifting gear 53, it is connected to the driven shaft 52 through a coaxial reversing mechanism. The coaxial reversing mechanism is a prior art and will not be described in detail here. The lifting gear 53 rotates to drive the lifting rack 54 meshed therewith and the lifting rod 55 fixed thereto to move upward, thereby driving the lifting block 56 at the other end of the lifting rod 55 to slide upward from the lifting groove provided on the lower die 12, and lift up one end of the stamped sheet, so that a clearance is formed between the sheet and the upper end surface of the lower die for the operator's hand to be inserted, so that the operator can directly grab the upper and lower end surfaces of the sheet and remove the sheet. Avoid touching the side of the sheet to cause scratches on the operator's hand.

[0064] To summarize, by providing a moving mechanism, it is suitable to move the plate after stamping to the picking station to move it away from the upper die, thereby improving the safety of the operator taking out the formed plate and placing the plate for processing. At the same time, by providing a lifting mechanism, when the processed plate is moved to the bending station, one end of the plate is lifted to form a picking gap, so that the operator can directly grab the upper and lower end surfaces of the plate to pick it up.
