Description

Technical Field

[0001] This utility model relates to the field of metal stamping technology for electronic products, and specifically to a sheet material stamping device. Background Technology

[0002] Stamping is a forming method that uses a press and dies to apply external force to sheet metal, strip, tube, and profile, causing plastic deformation or separation to obtain stamped parts of the required shape and size. Electronic products such as mobile phones require a large number of stamped parts, which are made from metal sheets through stamping. Current stamping mechanisms for processing these parts have only one stamping position, meaning that only one stamped part can be processed at a time, resulting in low production efficiency.

[0003] In the existing technology, there are also dual-station stamping machines, but during feeding, either manual placement is required, which is prone to accidents, or a robotic arm is required to grasp the material, which is inaccurate and can easily damage the metal parts of electronic products. Utility Model Content

[0004] To solve the above problems and overcome the shortcomings of the prior art, this utility model provides a sheet material stamping device; The first technical problem to be solved is that existing dual-station stamping machines either require manual placement of materials during loading, which can easily lead to accidents, or require a robotic arm to grasp them, which is inaccurate and can easily damage the metal parts of electronic products.

[0005] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: the sheet material stamping device includes two stamping stations symmetrically arranged; characterized in that: a raw material placement frame is provided at the center position between the two stamping stations, and a preset number of sheet materials are stacked in the raw material placement frame. The raw material placement frame has an open structure at both ends. A chamber for accommodating a predetermined number of sheet-like raw materials is located in the middle of the frame. A movable plate is slidably connected to the bottom of the frame. The upper end face of the moving plate is symmetrically provided with a bottom film groove to accommodate a sheet material. The symmetrically provided bottom film grooves are respectively set with a stamping station and a raw material placement frame. The bottom of the moving plate is directly or indirectly fixed to the slider. The slider is slidably connected to the slide groove. The slider reciprocates in the horizontal direction under the drive of the output part of the drive structure.

[0006] Furthermore, the upper edge of the bottom film groove is flared.

[0007] Furthermore, the flare size is larger than the size of the sheet material, and the flare is compatible with the chamfer on the outer edge of the stamping head of the stamping station.

[0008] Furthermore, the drive structure is a linear reciprocating hydraulic cylinder, a linear reciprocating air cylinder, a linear reciprocating motor module, or a linear reciprocating lead screw assembly.

[0009] Furthermore, both the raw material placement frame and the stamping station are fixed to the base plate by brackets.

[0010] Furthermore, the slide is designed to be concave, and the bottom of the slide is surrounded by multiple support surfaces. The slider is slidably connected to the slide via a guide rail, and the support surfaces at the bottom of the slide support the slider.

[0011] The beneficial effects of this utility model are: One advantage of this invention is that it provides automatic feeding and has a dual-station stamping device. The sheet material can fall into the bottom mold groove of the moving plate under the action of gravity. With the reciprocating movement of the moving plate, it can realize automatic feeding and switch between stamping and feeding stations. One advantage of this invention is that the upper edge of the bottom film groove is flared, which makes it easier for sheet materials to fall smoothly into the bottom film groove of the movable version under the action of gravity. One advantage of this invention is that the chamfer on the outer edge of the punching head at the flaring and stamping station is compatible with the punching head. This facilitates the punching head falling into the bottom mold groove of the moving plate for stamping. In particular, the fit between the chamfer and the flaring not only ensures the accuracy of the horizontal position but also the accuracy of the vertical stamping, avoiding over-stamping due to mechanical errors. The support surface at the bottom of the chute supports the slider and can withstand greater pressure. Attached Figure Description

[0013] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "left," "right," "rear," "lower left," "upper right," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] The specific embodiment of this utility model is as follows: The sheet material stamping device includes two stamping stations 2 symmetrically arranged; the improvement of this utility model is as follows: A raw material placement frame 1 is provided at the center position between the two stamping stations 2, and a preset number of sheet materials are stacked in the raw material placement frame 1. As a preferred option Both the raw material placement frame 1 and the stamping station 2 can be fixed to the base plate 9 by the bracket 10; The raw material placement frame 1 has an open structure at both ends. A chamber for accommodating a predetermined number of sheet-like raw materials is located in the middle of the raw material placement frame 1. A movable plate 3 is slidably connected to the bottom of the raw material placement frame 1. The upper end face of the moving plate 3 is symmetrically provided with a bottom film groove 4 for accommodating a sheet material. The symmetrically provided bottom film grooves 4 are respectively set with a stamping station 2 and a raw material placement frame 1. The moving plate 3 reciprocates in the horizontal direction under the drive of the output of the drive structure 8. With the reciprocating movement of the moving plate 3, it can automatically feed materials and switch the stamping and feeding stations of the moving plate 3 with the bottom film groove 4 containing the sheet material. As a preferred embodiment of this utility model: The upper edge of the bottom film groove 4 is set as an flared opening 5.

[0015] The flared opening 5 is larger than the size of the sheet material, so that the sheet material can fall into the bottom mold groove 4 of the moving plate 3 under the action of gravity or the pressing action of the stamping head 6. Furthermore, with the reciprocating motion of the moving plate 3, automatic material feeding and switching between the stamping and feeding stations are achieved; To ensure accuracy, the moving plate 3 is further supported by the output of the drive structure 8 and slidably connected to the bottom of the raw material placement frame 1.

[0016] Furthermore, the bottom of the movable plate 3 is directly or indirectly fixed to the slider 11, the slider 11 is slidably connected to the slide groove 13, and the slider 11 reciprocates in the horizontal direction under the drive of the output of the drive structure 8.

[0017] As a supplement, the drive structure 8 is a linear reciprocating motion structure used to drive the slider 11 to reciprocate linearly, including but not limited to a linear reciprocating hydraulic cylinder, a linear reciprocating air cylinder, or a linear reciprocating lead screw assembly.

[0018] Most importantly: The flared opening 5 is larger than the size of the sheet material, and the flared opening 5 is matched with the chamfer 7 on the outer edge of the stamping head 6 of the stamping station 2. On the one hand, it is convenient for the stamping head to fall into the bottom mold groove of the moving plate for stamping. In particular, this matching relationship can effectively achieve the limiting function. The fit between the chamfer and the flared opening can not only ensure the horizontal position accuracy, but also ensure the vertical stamping accuracy, avoiding over-stamping due to mechanical errors. Based on this, as the hydraulic cylinder of the stamping presses down further, the stamping head 6 and the moving plate 3 move together, without excessively stamping the sheet material. The slide groove 13 is set to be concave, and the bottom of the slide groove 13 is surrounded by multiple support surfaces 12. The slider 11 is slidably connected to the slide groove 13 through the guide rail. When the slider 11 moves down, the support surface 12 at the bottom of the slide groove 13 supports the slider 11, which can support the slider 11 and withstand greater pressure.
