Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel end cap processing, in particular to a cold pressing forming die for a thin-wall stainless steel end cap. Background Art

[0002] Thin-walled stainless steel end cap is a product used to plug stainless steel pipes. Usually, two ends are welded at the end of the pipe or at both ends of a round pipe to make a container. The manufacturing process and application range of thin-walled stainless steel end caps are wide, involving multiple industries. During the processing, the stainless steel end caps need to be cold pressed. During the processing, molds need to be used for matching molding, but it still has the following disadvantages in actual use:

[0003] During the cold pressing process, the cold pressing mold for thin-walled stainless steel heads is directly formed by the mold. During the forming process, the mold is directly pressed and formed, which may cause irregular deformation of the material at the closed end of the head, affecting the forming effect of the head;

[0004] After the thin-walled stainless steel head is formed by cold pressing, the operator needs to enter the forming area by hand. During the process of the operator directly removing it, if the mold is accidentally started, it will cause safety hazards and affect the operational safety at work. Utility Model Content

When the support plate 2 is working, when the processed material is set at the top of the support seat 1, it is supported by the support plate 2. A lifting spring 202 is fixed at the bottom of the support plate 2. When the lifting spring 202 is pressed by the support plate 2, the lifting spring 202 is pressed by the support plate 2. When the forming pressure block 402 descends under the downward pressure, the center position of the stainless steel head forming material is determined, an auxiliary ring 3 is fixed to the upper part of the peripheral side of the support seat 1, and the position of the raw material of the stainless steel head is limited by the auxiliary ring 3. An electric push rod 4 is arranged above the support plate 2, and the pressure plate 401 is driven to descend by the electric push rod 4. A fixing frame 403 is fixed on one side of the electric push rod 4, and the electric push rod 4 is connected to the top of the support seat 1 through the fixing frame 403. An electric push rod 2 5 is fixed on the side of the fixing frame 403 away from the electric push rod 1 4, and the flexible push plate 502 is driven to move by the electric push rod 2 5.

[0027] Specifically, a movable opening 102 is opened on the support seat 1 at the bottom of the molding cavity 101, and the inner diameter of the movable opening 102 is equal to the diameter of the support plate 2. When the molding cavity 101 is working, the movable opening 102 accommodates the support plate 2, the telescopic rod 201 and the lifting and lowering compression spring 202.

[0031] The operation process of this embodiment is as follows: when working, first put the raw material of the thin-walled stainless steel head on the top of the support seat 1. When placing it, the operator holds the edge of the head with his hand. When putting it down, the operator's hand is set in the opening 301. At this time, the raw material of the thin-walled stainless steel head is supported on the top of the support seat 1 and the support plate 2, and is set in the auxiliary ring 3. Then the thin-walled stainless steel head can be formed. During forming, the electric push rod 4 is started to drive the pressure plate 401 to descend. The descending of the pressure plate 401 drives the forming block 402 to descend. The descending of the forming block 402 to the contact support The support plate 2 is pressed tightly by the support plate 2 and the forming block 402. When the forming block 402 is pressed into the forming cavity 101, the forming work of the thin-walled stainless steel head is performed by the forming block 402 and the forming cavity 101. When the forming block 402 enters the forming cavity 101, the thin-walled stainless steel head is formed after the support plate 2 and the movable opening 102 are tightly fitted together through the telescopic rod 201. After forming, the electric push rod 4 is started to rise.
