Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping forming equipment based on ultra-thin hardware parts. Background Technology

[0002] Hardware parts refer to various metal products made from metal materials (such as steel, iron, aluminum, copper, stainless steel, etc.) through processing and forming. In order to make hardware parts into parts with the required shape, size and performance, stamping equipment (such as punch press) drives the mold to apply pressure to the metal sheet, strip or profile, causing the material to undergo plastic deformation or separation, thereby obtaining parts with the required shape, size and performance. Due to the continuous progress of technology, many electronic products and other equipment are developing vertically towards smaller size and lighter weight in line with the trend of the times. Therefore, ultra-thin metal sheets are used to make hardware parts.

[0003] However, when ultra-thin metal sheets are cut, the residual shear stress at the edges causes the sheet to bend more noticeably when placed in the mold. This results in unstable contact between the sheet and the mold and an imbalance of forces, causing the sheet to float and reducing the forming quality after stamping. Utility Model Content

[0004] This utility model provides a stamping forming equipment based on ultra-thin hardware parts, which can flatten the bent ultra-thin sheet material by rolling the flat material roller, and provide a certain pressure to press the ultra-thin sheet material to prevent it from floating.

[0005] This utility model provides a stamping forming equipment based on ultra-thin hardware parts, including:

[0006] The upper stamping die has symmetrically provided storage grooves at its bottom end, which are used to store the unfolded structure of the flattened ultra-thin sheet material.

[0007] The stretching structure is disposed inside the receiving groove. The stretching structure includes a push-out component for pushing out the receiving material, and a flattening component for flattening and fixing the ultra-thin sheet material during the stamping process.

[0008] The ejection assembly includes a guide bracket, with sliding blocks symmetrically fixed at the ends of the guide bracket, and a return spring fixedly fixed on one side of the sliding block, the return spring being fixedly connected to the upper stamping die;

[0009] The flattening assembly includes a wheel joint frame, with a support column fixedly arranged between the ends of the wheel joint frame. The support column is rotatably arranged inside the receiving groove via a pin. A flat material roller is rotatably arranged between the other ends of the wheel joint frame, and a guide pull frame is rotatably arranged on one side of the wheel joint frame.

[0010] In a stamping forming device based on ultra-thin hardware parts according to an embodiment of the present invention, the bottom end of the upper stamping die is symmetrically provided with a sliding groove, the sliding pressure block is slidably disposed on the inner side of the sliding groove, the return spring is fixedly disposed on the inner side of the sliding groove, and the guide bracket is initially inclined.

[0011] In a stamping forming equipment based on ultra-thin hardware parts according to an embodiment of the present invention, fixed short columns are fixedly provided on both sides of the wheel connecting frame, and an auxiliary display frame is rotatably provided on the outer side of the fixed short columns. A return torsion spring is fixedly provided on the outer side of the opposite end of the fixed short columns, and the other end of the return torsion spring is fixedly connected to the auxiliary display frame. An arc-shaped convex sliding part is provided at the bottom end of the auxiliary display frame, and a protective pad is fixedly provided on the outer side of the arc-shaped convex sliding part.

[0012] In a stamping and forming equipment based on ultra-thin hardware parts according to one embodiment of the present invention, the protective pad is made of rubber material, and the bottom of the protective pad is at the same level as the bottom of the flat material roller.

[0013] In a stamping and forming equipment based on ultra-thin hardware according to an embodiment of the present invention, limiting side blocks are fixedly provided on both sides of the wheel joint connecting frame, and the limiting side blocks are located below the fixed connecting short column.

[0014] In a stamping forming device based on ultra-thin hardware parts according to an embodiment of the present invention, a lower stamping die is provided below the upper stamping die, and a plurality of positioning posts are fixedly provided at the top of the lower stamping die.

[0016] The technical solution provided in this application embodiment can include the following beneficial effects: This application designs a stamping forming equipment based on ultra-thin hardware parts. Through the set ejection component and flat material roller, while the stamping upper die is pressed down, the flat material roller contacts the ultra-thin sheet material. As the stamping upper die is pressed down, the wheel joint connecting frame of the flat material roller tilts to one side, and the angle between the wheel joint connecting frame and the stamping upper die becomes smaller and smaller. Thus, the flat material roller will flatten the bent ultra-thin sheet material by rolling, and provide a certain pressure to press the ultra-thin sheet material to prevent material from floating. After the stamping upper die is pressed down to the end, the flat material roller will be completely stored in the receiving groove. This improves the stamping quality of the ultra-thin sheet material and prevents the flat material roller from affecting the ultra-thin sheet material.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] like Figures 1 to 5 As shown, this application provides a stamping forming equipment based on ultra-thin hardware parts, including: an expansion structure 4 disposed inside a receiving groove 102, the expansion structure 4 including an ejection component 5 for ejecting and receiving, and a flattening component 6 for flattening the ultra-thin sheet 3 during the stamping process, the ejection component 5 including a guide puller 501, a sliding pressure block 502 symmetrically fixedly disposed at the end of the guide puller 501, a return spring 503 fixedly disposed on one side of the sliding pressure block 502, the return spring 503 being fixedly connected to the stamping upper die 1, the flattening component 6 including a wheel connecting frame 601, a receiving column 603 fixedly disposed between the ends of the wheel connecting frame 601, the receiving column 603 being rotatably disposed inside the receiving groove 102 via a pin 604, a flattening roller 602 being rotatably disposed between the other ends of the wheel connecting frame 601, and the guide puller 501 being rotatably disposed on one side of the wheel connecting frame 601.

[0029] After adopting the above technical solution, during the stamping operation, the flattening roller 602 in the flattening component 6 will contact the ultra-thin sheet 3. During the pressing process of the upper stamping die 1, the flattening roller 602 will roll, and at the same time, the included angle between the wheel connecting frame 601 and the upper stamping die 1 will gradually decrease, while the included angle between the guide pull frame 501 and the wheel connecting frame 601 will gradually increase. At the same time, the return spring 503 will be compressed. In this way, the flattening roller 602 is in constant contact with the ultra-thin sheet 3. While the flattening roller 602 is rolling and moving, the bent ultra-thin sheet 3 is flattened. The flattening roller 602 can also press down the ultra-thin sheet 3 at the same time to prevent the phenomenon of material floating and improve the stamping quality of the ultra-thin sheet 3. After the upper stamping die 1 and the lower stamping die 2 are closed, the ejection component 5 and the flattening component 6 in the stretching structure 4 are stored in the receiving groove 102 to prevent them from affecting the stamping operation of the ultra-thin sheet 3.

[0030] Furthermore, the bottom end of the stamping upper die 1 is symmetrically provided with a sliding groove 103, the sliding pressure block 502 is slidably disposed inside the sliding groove 103, the return spring 503 is fixedly disposed inside the sliding groove 103, and the guide bracket 501 is initially tilted.

[0031] In an optional embodiment, as the upper stamping die 1 is pressed down, the angle between the wheel connecting frame 601 and the upper stamping die 1 gradually decreases, the sliding block 502 slides inside the block sliding groove 103, and the return spring 503 is compressed, so that when the upper stamping die 1 rises, the ejection component 5 can push the flattening component 6 to the initial position.

[0032] Among them, fixed short columns 607 are fixedly installed on both sides of the wheel connection frame 601. An auxiliary display frame 605 is rotatably installed on the outer side of the fixed short columns 607. A return torsion spring 606 is fixedly installed on the outer side of the opposite end of the fixed short columns 607. The other end of the return torsion spring 606 is fixedly connected to the auxiliary display frame 605. An arc-shaped sliding part 609 is provided at the bottom end of the auxiliary display frame 605. A protective pad 610 is fixedly installed on the outer side of the arc-shaped sliding part 609.

[0033] In an optional embodiment, while the protective pad 610 is in contact with the ultrathin sheet 3 and is still pressing down, the support frame 605 rotates slightly, which at the same time drives the reset torsion spring 606 to retract. This is to adapt to the change in the angle between the wheel connecting frame 601 and the stamping upper die 1, and to ensure that the protective pad 610 will always press down on the ultrathin sheet 3, further ensuring that the ultrathin sheet 3 will not shift.

[0034] For example, the protective pad 610 is made of rubber material, and the bottom of the protective pad 610 is at the same level as the bottom of the flat roller 602.

[0035] In an optional embodiment, when the ultra-thin sheet 3 is flattened, the protective pad 610 will come into contact with the surface of the ultra-thin sheet 3. The protective pad 610 is made of rubber material to prevent the parts from scratching the surface of the ultra-thin sheet 3, ensuring the appearance of the hardware, and can also press down the ultra-thin sheet 3 while flattening to prevent the ultra-thin sheet 3 from floating.

[0036] For example, limiting side blocks 608 are fixedly provided on both sides of the wheel connection frame 601, and the limiting side blocks 608 are located below the fixed connection short column 607.

[0037] In an alternative embodiment, as the angle between the wheel connecting frame 601 and the upper stamping die 1 becomes smaller, it indicates that the distance between the upper stamping die 1 and the lower stamping die 2 is getting shorter. This causes the included angle between the arc-shaped sliding part 609 and the flat material roller 602 to change. The setting of the limiting side block 608 is to prevent the arc-shaped sliding part 609 from getting too close to the flat material roller 602, so as to prevent affecting the quality of flattening the ultra-thin sheet material 3.

[0038] For example, a lower stamping die 2 is provided below the upper stamping die 1, and a plurality of positioning posts 201 are fixedly provided at the top of the lower stamping die 2. The positioning posts 201 are used to position the ultra-thin sheet material 3 waiting to be stamped.

[0039] In one optional embodiment, a plurality of positioning posts 201 are disposed at the triangular part of the ultra-thin sheet 3, and the ultra-thin sheet 3 is positioned by the triangular positioning method, so that the initial position of the ultra-thin sheet 3 is directly below the stamping upper die 1, which facilitates flattening and stamping.

[0040] For example, a hydraulic rod 101 is fixedly provided at the top of the upper stamping die 1, and the hydraulic rod 101 is externally connected to a hydraulic cylinder.

[0041] In an alternative embodiment, the hydraulic rod 101 can be extended or retracted by an external hydraulic cylinder, thereby providing stamping force to the upper stamping die 1.
