For the convenience of description, only the parts related to the present invention are shown in the figure.

[0035] Depend on Figures 1 to 6It can be seen that the spring sheet bending equipment includes a workbench 11, and also includes a conveying mechanism arranged on the workbench 11, a pre-bending mechanism 20, a vertical bending mechanism 30 and a horizontal bending mechanism 40 arranged in sequence along the conveying mechanism, and a pre-bending clamping mechanism 50a, a vertical bending clamping mechanism 50b and a horizontal bending clamping mechanism 50c are respectively arranged above the conveying mechanism at the positions corresponding to the pre-bending mechanism 20, the vertical bending mechanism 30 and the horizontal bending mechanism 40.

[0036] During bending, the conveying mechanism conveys the product to the pre-bending mechanism 20, the pre-bending pressing mechanism 50a presses the product on the conveying mechanism, and the pre-bending mechanism 20 bends the spring sheet of the product to a certain angle, usually 45 degrees; after the pre-bending pressing mechanism 50a is separated from the product on the conveying mechanism, the conveying mechanism conveys the product to the vertical bending mechanism 30, the vertical bending pressing mechanism 50b presses the product, and the vertical bending mechanism 30 continues to bend the product to an angle close to 90 degrees or greater than 90 degrees; the vertical bending pressing mechanism 50 After the product b is separated from the conveying mechanism, the conveying mechanism conveys the product to the horizontal bending mechanism 40, the horizontal bending and clamping mechanism 50c clamps the product on the conveying mechanism, and the horizontal bending mechanism 40 pushes the spring sheet of the product to continue to bend to the final shape; the spring sheet bending equipment of the embodiment of the present invention can bend the spring sheet into the final shape through the pre-bending mechanism 20, the vertical bending mechanism 30 and the horizontal bending mechanism 40, without the need for manual bending operations, and can improve the bending accuracy and bending efficiency, thereby solving the problem of low accuracy and low efficiency of manual bending of spring sheets.

[0037] In the embodiment of the present invention, Figure 1 It can be seen that the conveying mechanism includes a disc 12 rotatably mounted on a workbench 11, a plurality of tooling seats 13 spaced apart along the circumference of the disc 12, and a rotation driving mechanism for driving the disc 12 to rotate. Usually, the rotation driving mechanism is a motor.

[0038] Specifically, the pre-bending mechanism 20 , the vertical bending mechanism 30 , and the horizontal bending mechanism 40 are arranged at intervals along the circumference of the disk 12 , and are respectively fixed to the workbench 11 .

[0039] In the embodiment of the present invention, Figure 1 and Figure 2It can be known that the pre-bending mechanism 20 includes a pre-bending bracket 21, a pre-bending lifting drive mechanism 22 fixed on the pre-bending bracket 21, and a pre-bending head 23 installed on the output portion of the pre-bending lifting drive mechanism 22, and a pre-bending roller 24 is rotatably installed on the pre-bending head 23. During pre-bending, the pre-bending lifting drive mechanism 22 drives the pre-bending head 23 and the pre-bending roller 24 to rise, and the pre-bending roller 24 hits the spring sheet. As the pre-bending lifting drive mechanism 22 drives the pre-bending head 23 and the pre-bending roller 24 to continue to rise, the spring sheet is bent and deformed, and the spring sheet is bent to a certain angle; the pre-bending roller 24 contacts the spring sheet, which not only facilitates the deformation of the spring sheet, but also avoids scratching the spring sheet.

[0040] Specifically, the pre-bending mechanism 20 also includes a pre-bending head mounting seat 25 fixed on the output part of the pre-bending lifting drive mechanism 22, and the pre-bending head 23 is rotatably mounted on the pre-bending head mounting seat 25. An angle adjustment structure is provided between the pre-bending head 23 and the pre-bending head mounting seat 25. The angle adjustment structure includes an elastic telescopic member arranged between one side of the rotation direction of the pre-bending head 23 and the pre-bending head mounting seat 25 on the corresponding side, and a pre-bending head adjusting member 26 arranged on the pre-bending head mounting seat 25 on the side of the pre-bending head 23 away from the elastic telescopic member. A locking member is provided between the pre-bending head mounting seat 25 and the pre-bending head 23; the angle of the pre-bending head 23 can be adjusted by the pre-bending head adjusting member 26 and the elastic telescopic member, thereby adjusting the position of the pre-bending roller 24, which can further improve the bending accuracy. Usually, the elastic telescopic member is a spring, the pre-bending head adjustment member 26 is a micrometer knob, a threaded rod, etc., and the locking member is a locking bolt; the pre-bending lifting drive mechanism 22 is an electric cylinder, and can also be a pneumatic cylinder.

[0041] In order to improve the bending efficiency, multiple products can be placed on each tooling seat 13, and a pre-bending lifting drive mechanism 22 and a pre-bending head 23 installed on the output part of the pre-bending lifting drive mechanism 22 are respectively provided on the pre-bending bracket 21 corresponding to each product.

[0042] Depend on Figure 5 and Figure 6 It can be known that the pre-bending clamping mechanism 50a includes a clamping lifting drive mechanism 51, a clamping bracket 52 fixed on the output part of the clamping lifting drive mechanism 51, a product pressing head 53 is installed on the clamping bracket 52, and usually, a buffer structure is provided between the product pressing head 53 and the clamping bracket 52, and the buffer structure includes a cylinder fixed on the clamping bracket 52, a mounting rod fixedly connected to the product pressing head 53, the mounting rod is slidably connected to the clamping bracket 52 and inserted into the cylinder, a retaining ring is provided on the portion of the mounting rod located outside the cylinder, and a spring is provided between the bottom of the cylinder and the portion of the mounting rod inserted into the cylinder. When clamping, the spring can play a buffering role to avoid crushing the product.

[0043] Specifically, a spring sheet pressing head (not shown in the figure) is provided on the side of the product pressing head 53, and the spring sheet pressing head is provided corresponding to the bending position on the spring sheet. During pre-bending, the spring sheet pressing head is pressed at the bending position of the spring sheet, so as to facilitate deformation of the spring sheet during pre-bending. Usually, the spring sheet pressing head and the product pressing head 53 are of a split structure, and a fastener is provided between the spring sheet pressing head and the product pressing head 53, and the fastener is a bolt, and the spring sheet pressing head can be adjusted or replaced according to the bending position, so as to improve the bending accuracy.

[0044] Correspondingly, a support lifting drive mechanism is fixed on the pre-bending bracket 21, and a support member corresponding to the spring sheet pressure head is fixed on the output part of the support lifting drive mechanism. Usually, the support lifting drive mechanism is a cylinder. During pre-bending, the spring sheet can be adhered between the spring sheet pressure head and the support member, which is convenient for the spring sheet to deform and can improve the bending accuracy.

[0045] Depend on Figure 1 and Figure 3 It can be seen that the vertical bending mechanism 30 includes a vertical bending bracket 31, a vertical bending lifting drive mechanism 32 fixed on the vertical bending bracket 31, and a vertical elbow 34 installed on the output part of the vertical bending lifting drive mechanism 32, and a vertical bending roller 35 is rotatably installed on the vertical elbow 34. During vertical bending, the vertical bending lifting drive mechanism 32 drives the vertical elbow 34 and the vertical bending roller 35 to rise, so that the vertical bending roller 35 contacts the bending part of the spring sheet, and the pre-bent elasticity can be bent continuously, and the spring sheet can be bent to an angle close to 90 degrees or greater than 90 degrees.

[0046] Specifically, a mounting plate 33 is fixed on the output part of the vertical bending lifting drive mechanism 32, and a vertical elbow mounting seat 36 is fixed on the mounting plate 33. The vertical elbow 34 is rotatably mounted on the vertical elbow mounting seat 36, and an angle adjustment structure is provided between the vertical elbow 34 and the vertical elbow mounting seat 36, and the angle adjustment structure includes an elastic telescopic member arranged between the vertical elbow mounting seat 36 on one side of the rotation direction of the vertical elbow 34 and the corresponding side, and a vertical elbow adjusting member 38 arranged on the vertical elbow mounting seat 36 on the side of the vertical elbow 34 away from the elastic telescopic member 37, and a locking member is provided between the vertical elbow mounting seat 36 and the vertical elbow 34; the angle of the vertical elbow 34 can be adjusted by the vertical elbow adjusting member 38 and the elastic telescopic member 37, and the vertical elbow 34 can be limited to the adjusted position by the locking member, so that the position of the vertical bending roller 35 can be adjusted, which can further improve the bending accuracy.

[0047] When multiple products can be placed on the tooling seat 13, a vertical elbow 34 is installed at the output portion of the vertical bending lifting drive mechanism 32 corresponding to each product, and a vertical bending roller 35 is rotatably installed on each vertical elbow 34. Since vertical bending is an intermediate step in the entire bending process, the bending accuracy requirement of this step is relatively lower than that of pre-bending and horizontal bending. Therefore, a vertical bending lifting drive mechanism 32 can be used to drive multiple vertical elbows 34 and vertical bending rollers 35 to move simultaneously for vertical bending.

[0048] The structure of the vertical bending and clamping mechanism 50b is the same as that of the pre-bending and clamping mechanism 50a. Since the vertical bending roller 35 of the vertical bending and clamping mechanism 50b is directly arranged corresponding to the bending position of the spring sheet, there is no need to arrange a spring sheet pressure head on the vertical bending and clamping mechanism 50b.

[0049] Depend on Figure 1 and Figure 4 It can be seen that the horizontal bending mechanism 40 includes a horizontal bending bracket 41, a horizontal bending drive mechanism 42 fixed on the horizontal bending bracket 41, and a horizontal elbow 43 installed on the output part of the horizontal bending drive mechanism 42, and a horizontal bending roller 44 is rotatably installed on the horizontal elbow 43. During horizontal bending, the horizontal bending drive mechanism 42 drives the horizontal elbow 43 and the horizontal bending roller 44 to move horizontally, so that the horizontal bending roller 44 is pressed against the bending part of the spring sheet. As the horizontal bending drive mechanism 42 continues to drive the horizontal elbow 43 and the horizontal bending roller 44 to move horizontally, the elasticity after vertical bending can continue to be bent, so that the spring sheet continues to be bent to the final shape. Usually, the horizontal bending drive mechanism 42 is an electric cylinder, and of course a pneumatic cylinder can be used.

[0050] Specifically, a horizontal elbow mounting seat 45 is fixed on the output part of the horizontal bending drive mechanism 42, and the horizontal elbow 43 is rotatably mounted on the horizontal elbow mounting seat 45. An angle adjustment structure is provided between the horizontal elbow 43 and the horizontal elbow mounting seat 45, and the angle adjustment structure includes an elastic telescopic member arranged between one side of the rotation direction of the horizontal elbow 43 and the horizontal elbow mounting seat 45 on the corresponding side, a horizontal elbow adjusting member 46 is arranged on the horizontal elbow mounting seat 45 at the side of the horizontal elbow 43 away from the elastic telescopic member, and a locking member is provided between the horizontal elbow mounting seat 45 and the horizontal elbow 43; the angle of the horizontal elbow 43 can be adjusted by the horizontal elbow adjusting member 46 and the elastic telescopic member, and the horizontal elbow 43 can be limited to the adjusted position by the locking member, the position of the horizontal bending roller 44 can be adjusted, and the bending accuracy can be further improved.

[0051] When multiple products can be placed on the tooling seat 13, a horizontal bending drive mechanism 42 is fixed on the horizontal bending bracket 41 corresponding to each product, and a horizontal elbow 43 is fixed on the output part of each horizontal bending drive mechanism 42. The spring sheet of each product is horizontally bent respectively, which can improve the bending accuracy.

[0052] The structure of the horizontal bending and clamping mechanism 50c is the same as that of the pre-bending and clamping mechanism 50a. Since the horizontal elbow 43 of the horizontal bending and clamping mechanism 50c is directly arranged corresponding to the bending position of the spring sheet, there is no need to arrange a spring sheet pressure head on the horizontal bending and clamping mechanism 50c.

[0053] In order to facilitate installation and save installation space, a bracket 14 located at the side of the disc 12 is fixed on the workbench 11, and a support plate located above the disc 12 is fixedly connected to the bracket 14. The pre-bending and clamping mechanism 50a, the vertical bending and clamping mechanism 50b, and the horizontal bending and clamping mechanism 50c are respectively installed on the support plate. Specifically, the clamping and lifting driving mechanism 51 is fixed on the support plate, and a guide mechanism is respectively provided between the opposite sides of the clamping and lifting driving mechanism 51 and the clamping bracket 52, so that the product pressing head 53 can be accurately pressed onto the product. Usually, the guide mechanism is a guide rod sliding sleeve assembly.

[0054] In the embodiment of the present invention, the spring sheet bending equipment further includes a loading mechanism (not shown in the figure), a unloading mechanism 60, a detection mechanism 70, a transporting and conveying mechanism 80 and a steering adjustment mechanism 90 fixed on the workbench 11. The loading mechanism places the product into the tooling seat 13 on the disc 12, and the rotary drive mechanism drives the disc to rotate, and the product passes through the pre-bending mechanism 20, the vertical bending mechanism 30 and the horizontal bending mechanism 40 in sequence to perform corresponding actions. The unloading mechanism 60 removes the product that has undergone the bending operation from the tooling seat 13 on the disc 12, and places it in the detection mechanism 70 to detect whether it is qualified. The transporting and conveying mechanism 80 transports the product at the detection mechanism 70 to the steering adjustment mechanism 90. After the product is turned by the steering adjustment mechanism 90, it is convenient for subsequent plate placement.

[0055] Specifically, the unloading mechanism 60 includes a unloading bracket, a unloading translation drive mechanism fixed on the unloading bracket, and a material picking and lifting drive mechanism fixed on the output part of the unloading translation drive mechanism. A clamping structure is installed on the output part of the material picking and lifting drive mechanism. Usually, the unloading translation drive mechanism is an electric cylinder, the material picking and lifting drive mechanism is a pneumatic cylinder, and the clamping structure is a cylinder clamp.

[0056] Specifically, the detection mechanism 70 is fixed to the detection translation drive mechanism on the workbench 11, the tooling seat fixed to the output part of the detection translation drive mechanism, and the CCD camera arranged above the detection translation drive mechanism; the unloading mechanism 60 takes the product down and places it on the tooling seat on the output part of the detection translation drive mechanism, and the detection translation drive mechanism transports the product to the bottom of the CCD camera for detection, and after the detection is completed, the detection translation drive mechanism transports the product to the transporting and conveying mechanism 80. Usually, the detection translation drive mechanism is an electric cylinder.

[0057] Specifically, the transporting and conveying mechanism 80 includes a transporting bracket, a transporting translation driving mechanism fixed on the transporting bracket, and a transporting lifting driving mechanism fixed on the output part of the transporting translation driving mechanism, and a clamping claw structure is installed on the output part of the transporting lifting driving mechanism; the clamping claw structure is driven by the transporting lifting driving mechanism to fall and pick up the product in the tooling seat on the output part of the detection translation driving mechanism, and transported to the steering adjustment mechanism 90 through the transporting translation driving mechanism.

[0058] Specifically, the steering adjustment mechanism 90 includes a steering translation drive mechanism, a steering drive mechanism fixed on the output part of the steering translation drive mechanism, and a tooling seat fixed on the output part of the steering drive mechanism. The transporting and conveying mechanism 80 places the product in the tooling seat on the output part of the steering drive mechanism, and after the steering drive mechanism drives the tooling to rotate 90 degrees, the steering translation drive mechanism transports it to the side away from the disc 12, so as to facilitate the subsequent panning work. Usually, the steering translation drive mechanism is an electric cylinder, and the steering drive mechanism is an electric turntable or a pneumatic turntable.

[0059] In an embodiment of the present invention, the spring sheet bending equipment also includes an electric control system, which includes a PLC controller, a display screen, a power supply, a control switch, etc. Of course, the spring sheet bending equipment can also share the electric control system with the automated production equipment.

[0060] The present invention also discloses a spring sheet bending method based on the above structure, and the spring sheet bending method comprises the following steps:

[0061] Step 1: Pre-bending

[0062] The conveying mechanism conveys the product to the pre-bending mechanism 20, the pre-bending and pressing mechanism 50a presses the product on the conveying mechanism, and the pre-bending mechanism 20 pre-bends the spring sheet of the product to a certain angle, usually 45 degrees. Specifically, the rotary drive mechanism drives the disc 12 to rotate, and the product is conveyed through the tooling seat 13 on the disc 12.

[0063] Step 2: Vertical bending

[0064] After the pre-bending and clamping mechanism 50a detaches from the product on the conveying mechanism, the conveying mechanism conveys the product to the vertical bending mechanism 30, the vertical bending and clamping mechanism 50b clamps the product, and the vertical bending mechanism 30 continues to bend the product to bend the spring sheet of the product to an angle close to 90 degrees or greater than 90 degrees.

[0065] Step 3: Horizontal bending

[0066] After the vertical bending and clamping mechanism 50b is separated from the product on the conveying mechanism, the conveying mechanism conveys the product to the horizontal bending mechanism 40, and the horizontal bending and clamping mechanism 50c clamps the product on the conveying mechanism, and the horizontal bending mechanism 40 pushes the spring sheet of the product to continue bending to the final shape.
