DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a small bend angle forming device includes: a base plate 100, a positioning and clamping mechanism 200, a forming cam mechanism 300, a rotating seat 400, a first forming mechanism 500, a second forming mechanism 600, a clamping mechanism 700 and an actuator 800. First, the two ends of the product are clamped by the clamping mechanism 700 and the bending machine chuck respectively, and then the product is pressed by the positioning and clamping mechanism 200. Then, the actuator 800 drives the rotating seat 400 to rotate. When the rotating seat 400 rotates, the clamping mechanism 700 can bend the product, and the first forming mechanism 500 and the second forming mechanism 600 can drive the clamping mechanism 700 to move in the X direction (horizontal direction) and the Z direction (vertical direction). Therefore, the clamping mechanism 700 can also move left and right or up and down on the rotating seat 400 when the rotating seat 400 rotates, thereby realizing three-dimensional bending forming of the product.

[0040] Among them, the base plate 100 is a plate-like structure; the positioning and clamping mechanism 200 is connected to the base plate 100, and the positioning and clamping mechanism 200 is used to clamp the product; the positioning and clamping mechanism 200 can press and support the product, and can also fit with the surface of the product.

[0041] The molding cam mechanism 300 is connected to the base plate 100, and the molding cam mechanism 300 is provided with a first cam surface 320 and a second cam surface 330; the molding cam mechanism 300 is a cam-like structure, and its principle is also similar to that of a cam. The first cam surface 320 and the second cam surface 330 are designed as specific shape trajectories. The first cam surface 320 and the second cam surface 330 can drive the first molding mechanism 500 and the second molding mechanism 600 to move through the principle of the cam structure, thereby adjusting the positions of the first molding mechanism 500 and the second molding mechanism 600.

[0042] The rotating seat 400 is rotatably connected to the molding cam mechanism 300; it should be emphasized here that the molding cam mechanism 300 is fixed, and the rotating seat 400 can rotate relative to the molding cam mechanism 300, so the rotating seat 400 can drive the first molding mechanism 500 and the second molding mechanism 600 to interact with the first cam surface 320 and the second cam surface 330 respectively.

[0043] It should be added here that in a general structure, the cam actively rotates to drive other structures to move, while in the present device, the forming cam mechanism 300 that acts as a cam is fixed, and the rotating seat 400 drives the first forming mechanism 500 and the second forming mechanism 600 to move on the forming cam mechanism 300, thereby achieving the effect of cam driving.

[0044] The first molding mechanism 500 is movably connected to the rotating seat 400. When the rotating seat 400 rotates, the first cam surface 320 controls the position of the first molding mechanism 500. The first molding mechanism 500 can move along the X-axis, and the first molding mechanism 500 moves against the first cam surface 320. As the rotating seat 400 rotates, the first molding mechanism 500 can move according to the shape and trajectory of the first cam surface 320, that is, the first molding mechanism 500 will move to the corresponding X-axis position when the rotating seat 400 rotates to the corresponding position.

[0045] The second molding mechanism 600 is movably connected to the first molding mechanism 500. When the rotating seat 400 rotates, the second cam surface 330 controls the position of the second molding mechanism 600. The second molding mechanism 600 can move along the X-axis, and the second molding mechanism 600 moves against the second cam surface 330. As the rotating seat 400 rotates, the second molding mechanism 600 can move according to the shape and trajectory of the second cam surface 330, that is, the second molding mechanism 600 will move to the corresponding Z-axis position when the rotating seat 400 rotates to the corresponding position.

[0046] The clamping mechanism 700 is connected to the second molding mechanism 600 and is used to clamp the product; the clamping mechanism 700 can move along the X-axis and Z-axis directions through the first molding mechanism 500 and the second molding mechanism 600, so the clamping mechanism 700 can also move up and down and horizontally when moving along the arc trajectory, thereby driving the three-dimensional bending of the product.

[0047] The actuator 800 is disposed on the bottom plate 100, and is linked to the rotating seat 400 and used to drive the rotating seat 400 to rotate. In the actual structure, one end of the rotating seat 400 is hinged to the molding cam mechanism 300 and the other end is hinged to the actuator 800, so the actuator 800 can drive the rotating seat 400 to rotate.

[0048] The actuator 800 can drive the rotating seat 400 to rotate, and plays a driving role. The actuator 800 is a linear actuator 800. In the actual structure, the actuator 800 can be set as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder and other components.

[0049] The product not only needs to be stretched and bent during molding, but also needs to be stretched and bent in the X direction and the Z direction to form a bend angle. Therefore, during molding, the rotating seat 400 can bend the product by rotating, and at the same time, the clamping mechanism 700 moves in the X direction and the Z direction according to the shape trajectory of the first cam surface 320 and the second cam surface 330, so that a bend angle is formed and the stability of the product size is maintained on the basis of achieving three-dimensional bending.

[0050] like Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, based on the above embodiment, the molding cam mechanism 300 includes an arc seat 310 , the first cam surface 320 is set as the outer edge surface of the arc seat 310 , and the second cam surface 330 is set as the arc inclined surface of the arc seat 310 .

[0051] Preferably, the side of the arc seat 310 is the outer edge surface, which is similar to the cam surface of a general cam structure. The upper plane or upper end surface of the arc seat 310 is an arc-shaped inclined surface, which is similar to an arc-shaped slope structure, and one end of the arc-shaped inclined surface is lower and the other end is higher, so it can play the role of a cam surface.

[0052] like Figure 1 , Figure 3 , Figure 7 As shown, on the basis of the above embodiment, the molding cam mechanism 300 further includes an articulated seat 340, the articulated seat 340 is located at the center of the arc seat 310, and the rotating seat 400 is rotatably connected to the articulated seat 340. Preferably, the articulated seat 340 has an articulated shaft, and the end of the rotating seat 400 is connected to the articulated shaft, so that the rotating seat 400 can rotate around the articulated shaft.

[0053] It should be noted that the hinge seat 340 and the arc seat 310 are both fixed on the bottom plate 100 , and the hinge seat 340 is located at the center of the arc seat 310 , so that when the rotating seat 400 rotates around the hinge seat 340 , the first molding mechanism 500 and the second molding mechanism 600 can rotate along the trajectory of the arc seat 310 .

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, on the basis of the above embodiment, the first molding mechanism 500 includes a horizontal sliding seat 510, a first driving element 520 and a first molding wheel 530, the horizontal sliding seat 510 is movably connected to the rotating seat 400, the first driving element 520 is fixed on the rotating seat 400, the first driving element 520 is connected to the horizontal sliding seat 510 and can drive the horizontal sliding seat 510 to move, the first molding wheel 530 is connected to the horizontal sliding seat 510, and the first driving element 520 can drive the first molding wheel 530 to rest on the first cam surface 320 through the horizontal sliding seat 510.

[0055] Preferably, the horizontal sliding seat 510 can move horizontally along the X-axis direction on the rotating seat 400, and the first driving element 520 can be a hydraulic cylinder or a pneumatic cylinder. The first driving element 520 drives the horizontal sliding seat 510 to move and makes the first molding wheel 530 press against the first cam surface 320. When the rotating seat 400 rotates, the first molding wheel 530 moves along the first cam surface 320, so the stroke position of the horizontal sliding seat 510 can be controlled by the shape trajectory of the first cam surface 320, that is, the first cam surface 320 can control the position of the horizontal sliding seat 510 on the X-axis.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, on the basis of the above embodiment, the second molding mechanism 600 includes a vertical sliding seat 610, a second driving element 620 and a second molding wheel 630, the vertical sliding seat 610 is movably connected to the horizontal sliding seat 510, the second driving element 620 is fixed on the horizontal sliding seat 510, the second driving element 620 is connected to the vertical sliding seat 610 and can drive the vertical sliding seat 610 to move, the second molding wheel 630 is connected to the vertical sliding seat 610, and the second driving element 620 can drive the second molding wheel 630 to rest on the second cam surface 330 through the vertical sliding seat 610.

[0057] Preferably, the vertical sliding seat 610 can move up and down along the Z-axis direction on the rotating seat 400, and the second driving element 620 can be a hydraulic cylinder or a pneumatic cylinder. The second driving element 620 drives the vertical sliding seat 610 to move and makes the second molding wheel 630 press against the second cam surface 330. When the rotating seat 400 rotates, the second molding wheel 630 moves along the second cam surface 330, so the stroke position of the vertical sliding seat 610 can be controlled by the shape trajectory of the second cam surface 330, that is, the second cam surface 330 can control the position of the vertical sliding seat 610 on the Z-axis.

[0058] It should be noted that the principle of the device is actually to allow the first molding wheel 530 and the second molding wheel 630 to follow the corresponding XY plane trajectory and Z direction trajectory according to the first cam surface 320 and the second cam surface 330 of specific shapes, so that the clamping mechanism 700 can follow the corresponding three-dimensional trajectory.

[0059] During molding, the clamping mechanism 700 clamps the end of the product, and then the positioning and pressing mechanism 200 presses the product. Then, the piston rod of the actuator 800 drives the rotating seat 400 to rotate. The rotation stroke of the rotating seat 400 cooperates with the movement stroke of the horizontal sliding seat 510 and the vertical sliding seat 610, so that the clamping mechanism 700 bends the product while bending the product in the X direction and the Z direction, so the curved corner of the product can be formed according to the designed first cam surface 320 and the second cam surface 330.

[0061] Preferably, the third driving element 730 can be set as a hydraulic cylinder or a pneumatic cylinder, and the fixed clamping block 710 and the movable clamping block 720 can form an upper and lower clamping effect. Since the clamping mechanism 700 can rotate with the rotating seat 400 and can also move in the X direction and the Z direction, after clamping the product, it can drive the product to bend, thereby achieving a three-dimensional bending effect, and there is no need to use high-strength rubber, so the dimensional stability of the product will not be reduced due to wear.
