Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 3, A hydraulic sheet metal bending machine for adjusting the position of the bending lower die, including an operating table 1. A support frame 2 is fixed at the top of the operating table 1. A hydraulic cylinder 3 is embedded above the support frame 2. The power transmission end of the hydraulic cylinder 3 is connected to a pressing plate 4. A bending die 5 is installed at the bottom end of the pressing plate 4. A bending lower die 6 is arranged on one side of the support frame 2 at the top of the operating table 1. An adjusting mechanism 7 is arranged on one side of the bending lower die 6; The adjusting mechanism 7 includes a placement groove 701. The placement groove 701 is opened at the position corresponding to the bending lower die 6 at the top of the operating table 1. A sliding groove 702 is opened at the lower part inside the placement groove 701. A motor 703 is embedded on one side of the operating table 1. The power output end of the motor 703 is connected to a threaded rod 704. A slider 705 is sleeved on the outer wall of the end of the threaded rod 704 penetrating into the operating table 1. One end of the slider 705 passing through the sliding groove 702 is fixed with a limiting plate 706. The slider 705 is threadedly connected to the threaded rod 704. The slider 705 forms a sliding structure with the operating table 1 through the sliding groove 702. One side of the inner wall of the placement groove 701 is fixed with a first support rod 8, and one side of the first support rod 8 on the inner wall of the placement groove 701 is fixed with a second support rod 9.

[0028] By adopting the above technical solution, under the stability of the support frame 2, the hydraulic cylinder 3 makes the pressing plate 4 drive the bending die 5 to move the bending lower die 6 on the operating table 1, so as to stamp and form the material. The pressing plate 4 is disassembled and assembled with the bending die 5 through bolts, and the corresponding die is replaced according to requirements. The bending lower die 6 slides into the placement groove 701 and enters between the limiting plates 706. Start the motor 703 to make the threaded rod 704 drive the slider 705 to slide stably along the sliding groove 702, so that the limiting plate 706 drives the bending lower die 6 to adjust the position according to the die groove as required, avoiding the trouble of manual adjustment. At the same time, the bending lower die 6 slides stably through the first support rod 8 and the second support rod 9, and at the same time, it avoids the situation of shaking and deviation during the stamping and forming process.

[0029] Specifically, as Figure 1 and Figure 4 shown, an extension block 10 is fixed at one end of the bending lower die 6. A positioning mechanism 11 is arranged at the position corresponding to the extension block 10 on the outer wall of one side of the operating table 1. The positioning mechanism 11 includes a connection shell 1101. The connection shell 1101 is slidably connected to the outer wall of one side of the operating table 1. An electromagnet 1102 is embedded inside the connection shell 1101. A through groove 1103 is opened at the top of the connection shell 1101. A permanent magnet block 1104 is slidably connected inside the through groove 1103. The positioning mechanism 11 further includes an anti-collision pad 1105. The anti-collision pad 1105 is fixed above the electromagnet 1102 inside the connection shell 1101. A limiting groove 1106 is opened on the outer wall of the operating table 1 corresponding to the connection shell 1101. The connection shell 1101 is adhesively connected to the anti-collision pad 1105. The connection shell 1101 forms a sliding structure with the permanent magnet block 1104.

[0030] By adopting the above technical solution, when the bending lower die 6 enters the placement groove 701, one end of the extension block 10 is aligned with the through groove 1103 of the connection shell 1101. The electromagnet 1102 is activated to push the permanent magnet block 1104 with the same magnetic pole to slide, pass through the through groove 1103 and insert into the extension block 10, which further improves the stability by limiting the bending lower die 6. Through the limiting groove 1106, the connection shell 1101 moves along with the movement of the bending lower die 6. At the same time, an anti-collision pad 1105 is adhered inside the connection shell 1101 to prevent the permanent magnet block 1104 from falling and damaging the electromagnet 1102 after the electromagnet 1102 is disconnected.

[0031] Working principle: The hydraulic cylinder 3 fixed by the support frame 2 works to drive the pressing plate 4 to move the bending die 5 towards the operation table 1 and cover the bending lower die 6 for stamping. The bending lower die 6 axially enters the placement groove 701 and is limited. At the same time, it is sleeved outside the first support rod 8 and the second support rod 9 and is located between the two limiting plates 706. The motor 703 works to drive the threaded rod 704, so that the slider 705 drives the limiting plate 706 to slide stably along the sliding groove 702 and supports the bending lower die 6 to move and align with the bending die 5. When the bending lower die 6 axially enters the placement groove 701, the extension block 10 at one end is aligned with the through groove 1103. Then the electromagnet 1102 is activated to push the permanent magnet block 1104 with the same magnetic pole to pass through the through groove 1103 and out of the connection shell 1101, and then insert into the extension block 10 for positioning to prevent shaking during movement or stamping. The connection shell 1101 is slidably connected with the limiting groove 1106, so as to automatically adjust the position along with the movement of the bending lower die 6. The anti-collision pad 1105 prevents the permanent magnet block 1104 from sliding down and colliding to damage the electromagnet 1102 when the electromagnet 1102 is turned off.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
