[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 、 Figure 2 and Figure 3 As shown, the metal bending and pressing device provided in the embodiment of the present application comprises a base 1, a lower fixture 2, a conveying mechanism 3 arranged on the base 1 for conveying the lower fixture 2, and a bending and pressing mechanism arranged on the base 1. The bending and pressing mechanism comprises a support 4 fixedly arranged on the base 1, a bending and pressing assembly 5, and a driving assembly 6 arranged on the support 4 for driving the bending and pressing assembly 5 to rise and fall. The bending and pressing assembly 5 comprises a plurality of bending blocks 51, a plurality of elastic tensioning members 52, and a plurality of elastic tensioning members 53 arranged on the support 4. A lifting seat 53 connected to the lowering position, a push plate 54 driven by the driving component 6 and connected to the lifting seat 53 for sliding up and down, an upper jig 55 fixedly connected to the lower end of the lifting seat 53, an elastic member 56 connected to the lower end of the push plate 54 and the upper end of the upper jig 55, one end of the bending block 51 is hinged to the upper end surface of the upper jig 55, and the other end of the bending block 51 is connected to the lifting seat 53 through an elastic tensioning member 52, the push plate 54 is against the upper end surface of the bending block 51, and the lower jig 2 is provided with a avoidance hole 501 for avoiding the bending block 51 from bending.

[0019] The bending block 51 is hinged to the upper fixture 55 via a rotating shaft.

[0020] During actual use, the product to be bent and compacted is placed on the lower jig 2, and then the conveying mechanism 3 drives the lower jig 2 to move to the bottom of the bending and compacting mechanism, and then the driving mechanism drives the bending and compacting mechanism to move downward, so that the push plate 54 compresses the elastic part 56 and drives the upper jig 55 to move downward, so that the upper jig 55 presses the product, and then the push plate 54 continues to move downward under the drive of the driving mechanism, squeezing the upper end of the bending block 51 so that the bending block 51 rotates around the rotating axis, driving the elastic tensioning part 52 to stretch, and the other end of the bending block 51 passes through the avoidance hole 501 to bend the product.

[0021] In the above design, the bending and pressing mechanism can complete the pressing and bending of the product, improve work efficiency, save production costs, and avoid the possibility of loosening during the re-transfer and pressing process after bending.

[0022] Specifically: Figure 3 and Figure 4As shown, the elastic member 56 comprises a first column 561, a limiting head 562 arranged at the upper end of the first column 561, and a compression spring 563 sleeved on the first column 561. The limiting head 562 is concentric with the first column 561, and the diameter of the limiting head 562 is greater than that of the first column 561. The lower end of the first column 561 is fixedly connected with the lower jig 2. The push plate 54 is provided with a first slot in sliding connection with the limiting head 562 and a second slot in sliding connection with the first column 561. The two ends of the compression spring 563 are in abutment with the upper jig 55 and the push plate 54, respectively.

[0023] In actual use, when the push plate 54 moves downward, the lower end of the push plate 54 presses the compression spring 563, and drives the upper jig 55 to press downward. When the upper jig 55 is limited by the product, further movement of the push plate 54 will cause the compression spring 563 to be further compressed, the first column 561 moves upward relative to the second slot, and the limiting head 562 moves upward relative to the first slot.

[0024] In the above design, the structure design and specific implementation of the elastic member 56 can effectively realize the elastic connection of the push plate 54 and the upper jig 55.

[0025] Specifically, as shown in Figure 1 As shown, the conveying mechanism 3 comprises a linear guide rail 31 arranged on the base 1, a supporting plate 32 slidingly arranged on the linear guide rail 31, and a motor 33 pulley assembly arranged on the base 1 for driving the supporting plate 32 to slide along the linear guide rail 31. The motor 33 pulley assembly comprises a synchronous belt 36, a motor 33 fixedly arranged on the base 1, a driving pulley 34 arranged on the output shaft of the motor 33, and a driven pulley 35 arranged on the base 1. The driving pulley 34 and the driven pulley 35 are in transmission connection through the synchronous belt 36. The lower jig 2 is arranged on the supporting plate 32.

[0026] In actual use, the motor 33 drives the driving pulley 34 to rotate, and under the cooperation of the driven pulley 35, the synchronous belt 36 is driven to transmit power, so that the synchronous belt 36 drives the supporting plate 32 to move along the linear guide rail 31, thereby driving the supporting plate 32 to move.

[0027] In the above design, the structure design and specific implementation of the conveying mechanism 3 can effectively realize the stable conveying of the lower jig 2.

[0028] Specifically, as shown in Figure 2 and Figure 3 As shown, the elastic tensioning member 52 comprises a tension spring 521 and a screw 522 fixedly arranged on the lifting seat 53. One end of the tension spring 521 is connected with the screw 522, and the other end of the tension spring 521 is connected with the bending block 51.

[0029] In actual use, when the bending block 51 is pressed down by the push plate 54 to bend the product, the tension spring 521 is stretched.

[0030] The structural design and specific implementation of the elastic tensioning member 52 in the above design facilitate the resetting of the bending block 51 .

[0031] Specifically: Figure 1 As shown, the driving assembly 6 includes a linear bearing 61 arranged on the support 4, a guide column 62 sleeved in the linear bearing 61 and fixedly connected to the upper end of the lifting seat 53, and a cylinder 63 fixedly arranged on the support 4, and the output end of the cylinder 63 is fixedly connected to the push plate 54.

[0032] In actual use, the cylinder 63 drives the push plate 54 to drive the elastic tensioning member 52 to rise and fall, so that the elastic member 56 drives the lower fixture 2 and the lifting seat 53 to rise and fall. During the lifting and falling process of the lifting seat 53, the guide column 62 rises and falls synchronously.

[0033] In the above design, the structural design and specific implementation of the driving mechanism can effectively ensure the stability of the lifting and lowering of the bending and pressing assembly 5.

[0034] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
