Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a stamping die for a sheet metal shell. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). There are many forms of stamping dies. For example, a die for stamping a U-shaped part of a shell includes an upper die base 00 and a lower die base 01 that cooperate with each other. When working, the plate is placed between the two, and the upper die base 00 and the lower die base 01 are moved to cooperate and engage with each other to press the plate into a U-shaped structure.

[0003] However, in the existing structure, during the stamping process, workers need to place materials (sheet metal parts) and take materials after stamping. The tedious work leads to high labor intensity for workers on the one hand and high work risks on the other hand.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1 and Figure 2 The utility model provides a stamping die for a sheet metal shell, which includes an upper die base 00 and a lower die base 01 that work together; wherein, the upper die base includes a lower fixed base 000 that is fixed to a base and symmetrically arranged on the left and right, and a lower movable base 001 that is placed in the middle space of the lower fixed base 000 and convex in the middle; and the upper die base 00 includes an upper movable base 010 that cooperates with the lower movable base 001 and is n-shaped, and a top base 011 that supports the upper movable base 010; a placement platform 4 is formed at the upper position of the lower fixed base 000 for placing a plate (straight plate) before stamping.

[0019] When performing stamping work, the plate is placed on the placement platform 4; the driving structure drives the upper die base 00 to move downward, and the downwardly moved upper die base 00 presses the plate. When the upper die base 00 and the lower die base 01 are fully matched, the plate is pressed into the desired shape (U-shape).

[0020] See also Figure 1 and Figure 3 , a blanking structure for ejecting the stamped sheet is placed at a predetermined position of the lower die base 01; the blanking structure includes a accommodating chamber 1 arranged in the lower die base 01 and an ejection member 2 installed in the accommodating chamber 1 and partially extending outside the chamber; an opening for the ejection member 2 to extend out is provided on the top wall of the accommodating chamber 1; a reset spring 3 for driving the ejection member 2 to return upward is provided inside the accommodating chamber 1; specifically, in this embodiment, the ejection member 2 includes an ejection portion 21 of a columnar structure and a support portion 22 integrally formed with the ejection portion 21 and movably installed in the accommodating chamber 1; the support portion 22 is connected to the reset spring 3, and the support portion 22 and the reset spring 3 can be connected in abutment or fixed manner. The ejection member 2 is eccentrically arranged away from one side of the lower die base 01. When the eccentrically arranged ejection member 2 is extended, the sheet (after stamping) is ejected to one side, so that the sheet "dumps" out of the equipment.

[0021] The highest point of the ejection member 2 without pressure is lower than the height of the placement platform 4. During the downward movement of the upper die holder 00 for stamping, the ejection member 2 will be pressed into the accommodating chamber 1. During this process, the ejection member 2 will not affect the stamping process of the plate. After the stamping is completed, during the upward movement of the upper die holder 00, the ejection member 2 extends out under the elastic force of the return spring 3. Subsequently, the extended ejection member 2 pushes out the plate (after stamping) to achieve the blanking work.

[0022] See also Figure 3 In addition, the bottom side wall of the accommodating chamber 1 of the utility model is provided with a damping layer 6 of a predetermined height; after the pop-up member 2 is pressed, the surrounding of the support portion 22 contacts the damping layer 6. Under the friction of the damping layer 6, the support portion 22 (during the upward movement of the support portion 22) moves relatively slowly in the damping layer 6 stage, and after the support portion 22 moves out of the damping layer 6, it will be released instantly, so that the pop-up member 2 produces an instant impact effect, and under this impact effect, the elastic material effect of the pop-up member 2 is further optimized.

[0023] See also Figure 4 The present application under the second embodiment also provides another structure of a pop-up member 2. Specifically, the pop-up member 2 includes a top plate 23 hinged to the opening side end, and one side of the top plate 23 is connected to the return spring 3.

[0024] In summary, the utility model provides a stamping die for a sheet metal shell, including an upper die seat and a lower die seat that work together; wherein, the upper die seat includes a lower fixed seat fixed to the base, symmetrically arranged on the left and right, and a lower movable seat placed in the middle space of the lower fixed seat, with the middle part convex; and the upper die seat includes an upper movable seat that cooperates with the lower movable seat and is n-shaped, and a top seat that supports the upper movable seat; the upper position of the lower fixed seat forms a placement platform for placing the plate (straight plate) before stamping. When performing the stamping work, the plate is placed on the placement platform; the driving structure drives the upper die seat to move downward, and the lowered upper die seat presses the plate, and when the upper die seat and the lower die seat are fully matched, the plate is pressed into the desired shape (U-shaped). A blanking structure for ejecting the stamped plate is placed at a predetermined position of the lower die seat; the blanking structure includes a receiving chamber arranged in the lower die seat and an ejection member installed in the receiving chamber and partially extending outside the chamber; an opening for the ejection member to extend out is provided on the top wall of the receiving chamber; a reset spring for driving the ejection member to return upward is provided inside the receiving chamber; the ejection member includes an ejection portion of a columnar structure and a support portion integrally formed with the ejection portion and movably installed in the receiving chamber; the support portion is connected to the reset spring, and the support portion and the reset spring can be connected in abutment or fixed manner. The ejection member is eccentrically arranged away from one side of the lower die seat, and when the eccentrically arranged ejection member is extended, the plate (after stamping) is ejected to one side, so that the plate "dumps" out of the equipment. The utility model can eject the plate by the ejection member that is ejected upward after the plate is stamped into the desired shape by the stamping die, thereby realizing blanking work, reducing the labor intensity of the workers while increasing the safety of the operation.
