Description

Technical Field

[0001] The utility model relates to the technical field of automobile molds, and particularly relates to a blank-holder device for automobile molds. Background Technique

[0002] Automobile molds, in a narrow sense, refer to the general term for all the molds for stamping parts on an automobile body. That is, "automobile body stamping molds". For example, the top cover flanging die, the crossbeam reinforcement forming die, etc. When pressing and forming the metal plate of an automobile component, a blank-holder structure is required to press the side of the metal plate to ensure the surface finish, flatness and dimensional accuracy of the workpiece.

[0003] In an existing blank-holder device for automobile molds, after the metal plate is pressed and formed, the metal plate sinks into the bottom die, which is inconvenient to take out. It takes a long time to take out the pressed metal plate, reducing the blank-holder efficiency of the metal plate. Moreover, improper taking out may damage the metal plate, resulting in low precision of the metal plate. When pressing and forming the metal plate, the metal plate needs to be manually transferred to the upper side of the bottom die, and then the blank-holder structure presses the metal plate. The metal plate needs to be transferred once for each pressing, which is time-consuming and laborious, reducing the blank-holder efficiency and posing a danger to the staff, leading to unnecessary safety hazards. Therefore, a blank-holder device for automobile molds is proposed to solve the above-mentioned problems. Content of the Utility Model

Specific Embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] In the embodiment, from Figures 1-4Provided is a blank holder device for an automotive mold. The utility model includes a workbench 1, and is characterized in that: a bottom die 2 is fixedly connected to the top of the processing table 1. A sliding column 3 is slidably connected inside the bottom die 2. A connecting plate 4 is fixedly connected to the bottom of the sliding column 3. A rotating piece 5 is rotatably connected inside the connecting plate 4. A connecting column 6 is fixedly connected to the outside of the rotating piece 5. A sliding cylinder 7 is slidably connected to the outside of the connecting column 6. A first spring 22 is fixedly connected to the outside of the connecting column 6. A connecting member 8 that is rotatably connected to the inside of the processing table 1 is fixedly connected to the outside of the sliding cylinder 7. An installation frame 9 is fixedly connected to the top of the processing table 1. A first guide wheel 10 that is rotatably connected to the inside of the processing table 1 is rotatably connected inside the installation frame 9. A connecting frame 23 is slidably connected inside the installation frame 9. A second guide wheel 11 is rotatably connected inside the connecting frame 23.

[0027] Place the long metal plate between the first guide wheel 10 and the second guide wheel 11, and convey the metal plate to the top of the bottom die 2 through the first guide wheel 10 and the second guide wheel 11. Subsequently, through stamping the metal plate, the metal plate is located in the inner groove of the bottom die 2. When stamping the metal plate downward, the metal plate drives the sliding column 3 to move downward, and then makes the connecting plate 4 move downward, thereby driving the connecting piece 5 to move downward. Subsequently, the connecting column 6 slides out inside the sliding cylinder 7, so that the first spring 22 is compressed. The downward impact force of the sliding column 3 is converted into the elastic potential energy of the first spring 22. Subsequently, it is convenient to bounce the sliding column 3 upward, thereby bouncing the pressed metal plate upward, facilitating its removal.

[0028] Specifically, referring to Figure 2 , a first hydraulic rod 12 is fixedly connected to the inner top wall of the installation frame 9. The output end of the first hydraulic rod 12 is fixedly connected to the top of the connecting frame 23.

[0029] In this embodiment, start the first hydraulic rod 12, thereby driving the connecting frame 23 to move upward or downward, so that the second guide wheel 11 inside it moves upward or downward, adjusting the distance between the first guide wheel 10 and the second guide wheel 11, so that the distance between the two can adapt to the conveyance of metal plates of different thicknesses.

[0030] Specifically, referring to Figure 2 and Figure 4 , a first motor 13 whose output shaft is fixedly connected to the central axis of the second guide wheel 11 is fixedly connected to the outside of the connecting frame 23. A second motor 14 whose output shaft is fixedly connected to the central axis of the first guide wheel 10 is fixedly connected to the top of the processing table 1.

[0031] In this embodiment, by starting the first motor 13, the first motor 13 drives the second guide wheel 11 to rotate counterclockwise. Start the second motor 14, so that the second motor 14 drives the first guide wheel 10 to rotate clockwise, thereby conveying the metal plate from left to right.

[0032] Specifically, referring to Figure 1 and Figure 2 , a second hydraulic rod 15 is fixedly connected to the inner top wall of the mounting bracket 9. The output shaft of the second hydraulic rod 15 is fixedly connected to a punch 16. A fixed plate 17 is fixedly connected to the top of the processing table 1. The connecting frame 23 is slidably connected to the inside of the fixed plate 17.

[0033] In this embodiment, the second hydraulic rod 15 is started, so that the punch 16 moves downward, so that the punch 16 cuts the metal plate and transfers it to the inside of the bottom die 2. By the connecting frame 23 sliding inside the fixed plate 17, the height adjustment of the second guide wheel 11 is completed.

[0034] Specifically, referring to Figure 2 , a third hydraulic rod 18 is fixedly connected to the top of the punch 16. The output end of the third hydraulic rod 18 is fixedly connected to a pressure column 19 that is slidably connected to the inside of the punch 16.

[0035] In this embodiment, the third hydraulic rod 18 is started, so that the pressure column 19 moves downward, so that the pressure column 19 squeezes the metal plate downward, causing the metal plate to sink downward, and completing the stamping of the metal plate.

[0036] Specifically, referring to Figure 1 , Figure 2 and Figure 3 , a second spring 20 is fixedly connected to the outside of the sliding column 3. A control panel 21 is fixedly connected to the top of the processing table 1.

[0037] In this embodiment, the sliding column 3 is driven by the pressure column 19 to press downward, so that the second spring 20 is compressed, and the downward pressure on the sliding column 3 is converted into the elastic potential energy of the first spring 22 and the second spring 20. Subsequently, the elastic potential energy of the second spring 20 and the first spring 22 is released, so that the sliding column 3 slides upward to eject the stamped metal plate. The control panel 21 controls the stamping of the metal plate, the rightward conveyance of the metal plate, etc.

[0038] Working principle:

[0039] First: Place the long strip metal plate between the first guide wheel 10 and the second guide wheel 11. The metal plate is conveyed to the top of the bottom die 2 by the relative rotation of the first guide wheel 10 and the second guide wheel 11. Start the second hydraulic rod 15, so that the punch 16 moves downward, so that the punch 16 cuts the metal plate and transfers it downward into the inside of the bottom die 2. Start the third hydraulic rod 18, so that the pressure column 19 moves downward, so that the pressure column 19 squeezes the metal plate downward, causing the metal plate to sink downward, and completing the stamping of the metal plate, so that the metal plate is located in the inner groove of the bottom die 2;

[0040] Then: When the pressing column 19 presses the metal plate downward, the metal plate drives the sliding column 3 to move downward, and then drives the connecting plate 4 to move downward, thereby driving the connecting piece 5 to move downward. Subsequently, the connecting column 6 slides out of the inside of the sliding cylinder 7, so that the first spring 22 is compressed. The downward impact force of the sliding column 3 is converted into the elastic potential energy of the first spring 22, and then it is convenient to bounce the sliding column 3 upward, thereby bouncing the pressed metal plate upward, so as to facilitate taking out.
