[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 , the present invention provides a technical solution, a sheet metal multi-angle bending machine. Legs 11 are provided at the bottom of the table board 1, and a central groove 12 is provided in the middle of the top surface along the horizontal direction. The bottom end of the bracket 2 is fixed at a position near the four corners of the top surface of the table board 1. A stamping telescopic cylinder 22 is fixedly arranged vertically in the middle of the bracket 2. The adjustable forming parts 3 are arranged in pairs. The adjustable forming parts 3 include arc-shaped horizontal columns 31 arranged along the horizontal direction at the front and rear ends of the central groove 12. The outer arc surface of the arc-shaped horizontal column 31 is tangent to the top surface of the table board 1. A forming inclined surface 311 is provided along the axial direction at the relative position of the paired arc-shaped horizontal columns 31. The adjustable stamping parts 4 are plate parts connected to the bottom of the stamping telescopic cylinder 22 in pairs and capable of opening and closing adjustment. A transmission mechanism for driving the two arc-shaped horizontal columns 31 to rotate synchronously and in opposite directions is provided on the table board 1.

[0038] When stamping and bending a sheet, the transmission mechanism drives the two arc-shaped horizontal columns 31 to rotate, so that various included angles are formed between the two forming inclined surfaces 311; then, the opening and closing angle of the adjustable stamping part 4 is correspondingly adjusted to make it adapt to the included angle between the forming inclined surface 311; the sheet to be processed is placed on the top surface of the table board 1, and the sheet is pushed so that the position to be bent of the sheet is placed on the center line between the two arc-shaped horizontal columns 31; then the stamping telescopic cylinder 22 drives the adjustable stamping part 4 to press downwards as a whole to realize stamping and bending the sheet at a certain angle.

[0039] A vertical cylinder 21 is fixedly installed along the vertical direction in the middle of the bracket 2, and the top of the stamping telescopic cylinder 22 is fixedly sleeved inside the vertical cylinder 21. The vertical cylinder 21 facilitates the fixed installation of the stamping telescopic cylinder 22.

[0040] Refer to Figures 2-3 、9, on the front and rear walls of the inner cavity of the middle groove 12 near both ends, shaft seats 13 are respectively fixed. At both ends of the arc-shaped cross-column 31, short shafts 32 are respectively fixed. A gear 33 is fixedly sleeved on the outer end of the short shaft 32. The short shaft 32 is rotatably sleeved inside the shaft seat 13. The gears 33 at the corresponding ends of the two paired arc-shaped cross-columns 31 are meshed with each other. On the outer edge positions of the outer side walls of the gears 33 at both ends of the rear side arc-shaped cross-column 31, connecting shafts 331 rotatably connected to the piston rod ends of the corner telescopic cylinders 5 are provided. When the piston rod of the corner telescopic cylinder 5 expands and contracts, it will push and pull the gear 33 to rotate through the connecting shaft 331. Since the gears 33 at the ends of the two arc-shaped cross-columns 31 are correspondingly meshed, the synchronous reverse rotation of the two arc-shaped cross-columns 31 is realized, so as to flexibly adjust the angle between the forming inclined surfaces 311.

[0041] Refer to Figures 4-6 , the adjusting assembly 6 includes a horizontal square column 61 fixedly installed at the bottom end of the piston rod of the stamping telescopic cylinder 22 in the middle of the top surface. A chute 611 is provided at the center of the horizontal square column 61. A lead screw 62 is rotatably installed along the axial direction at the center of the chute 611. A plurality of sliders 63 are slidably clamped in the chute 611, and the sliders 63 are threadedly sleeved and matched with the lead screw 62. Traction ear seats 631 are respectively provided on the front and rear walls of the slider 63. The traction ear seats 631 are rotatably connected with a connecting member 10. Ball head seats 42 corresponding to the other ends of the connecting member 10 are respectively provided on the top parts of the inner side walls of the adjustable stamping parts 4. And a spherical shell rotatably sleeved and matched with the ball head part of the ball head seat 42 is provided at the other end of the connecting member 10. A plurality of vertical ear plates 41 are uniformly provided at the bottom of the inner side wall of the adjustable stamping part 4. A plurality of connecting columns 7 extending vertically are uniformly fixedly installed on the bottom surface of the horizontal square column 61. The vertical ear plates 41 are rotatably connected with the bottom ends of the connecting columns 7. Rotating the lead screw 62 causes the slider 63 to slide in the chute 611, and the adjustable stamping part 4 is pulled through the traction ear seat 631, the connecting member 10 and the ball head seat 42. Among them, the inclined pulling provides a component force towards the center direction to realize the inward swing of the adjustable stamping part 4, achieving the adjustment of reducing the included angle of the stamping surface. Reversely rotating the lead screw 62 can push open the two adjustable stamping parts 4 to increase the included angle of the stamping surface.

[0042] Among them, in order to facilitate the rotation of the lead screw 62, a runner 621 is fixedly sleeved at one end of the lead screw 62 passing through the end surface of the horizontal square column 61.

[0043] The connecting column 7 includes a vertical column 71 with its top fixed to the bottom surface of the horizontal square column 61 and a rotating shaft 72 vertically fixed to the bottom end of the side wall of the vertical column 71. The vertical ear plates 41 are respectively rotatably sleeved on the rotating shaft 72.

When the adjustable stamping part 4 synchronously presses down on the plate, the stamping cross column 81 aligns with the center of the bending part for stamping, facilitating the forming of the internal corner of the bent plate.

[0045] Participate in Figure 8 、 9 It also includes an external corner support part 9. The external corner support part 9 includes a support cross column 91 located directly below the position between the two arc-shaped cross columns 31, a plurality of guide rods 93 vertically fixed to the bottom surface of the support cross column 91, a mounting plate 92 horizontally fixed to the middle of the bottom surface of the middle groove 12, and a second spring 94 sleeved on the outer periphery of the top of the guide rod 93. An arc-shaped groove 911 is provided along the axial direction on the top surface of the support cross column 91. The bottom end of the guide rod 93 is slidably sleeved on the mounting plate 92, and a vertical hole 14 slidably sleeved and matched with the bottom end of the guide rod 93 is provided on the bottom surface of the middle groove 12. When the included angle between the two formed inclined surfaces 311 is small, during stamping, the external corner of the bent part of the plate is supported in the arc-shaped groove 911, facilitating the forming of the external corner of the bent part of the plate.

[0046] The positions of the support cross column 91 on the front and rear sides of the arc-shaped groove 911 are respectively arc-shaped convex surface structures, and the arc-shaped convex surface structures are tangent to the bottom of the arc-shaped cross column 31. This avoids the problem of movement interference of the support cross column 91 when the arc-shaped cross column 31 rotates.
