[0034] Reference Figures 1 to 6 As shown, the punching device proposed in the embodiment of the present application includes:

[0035] The turntable assembly 100 includes a turntable 110 and a first driving member 120, wherein the first driving member 120 is used to drive the turntable 110 to rotate;

[0036] a second driving member;

[0037] The punching assembly 200 is arranged in a one-to-one correspondence with the turntable assembly 100, and the punching assembly 200 is located above the turntable 110. The punching assembly 200 includes a stripping insert 210 and a plurality of punching parts 220. One end of the punching part 220 is movably arranged on the stripping insert 210; an inclined punch 221 is arranged at one end of the punching part 220, and the second driving member is used to drive the punching part 220 to move up and down so that the punch 221 passes through the stripping insert 210 and punches the workpiece 500 located on the turntable 110.

[0038] Therefore, the above-mentioned embodiment of the present application has at least the following beneficial effects: by setting the turntable 110, the workpiece 500 can be driven to rotate by the turntable 110, so that after each rotation of the workpiece 500 by a certain angle, the punching part 220 moves downward under the action of the second driving member, thereby driving the punch 221 to move downward and penetrate the stripping insert 210 to punch the workpiece 500, and because the punch 221 is tilted, the punch 221 is perpendicular to the workpiece 500, thereby realizing automatic continuous side punching at different positions on the workpiece 500. Compared with the related art, the embodiment of the present application continuously adjusts the position of the workpiece 500 to be punched by the turntable 110, and repeatedly drives the punching part 220 to move, thereby improving the punching efficiency.

[0039] It should be understood that the stripping insert 210 and the punching portion 220 are part of the upper die structure of the punching die. In the initial state (i.e., the die opening state), the punch 221 is retracted in the stripping insert 210. Under the action of the second driving member, the punch 221 passes through the stripping insert 210 to punch the workpiece 500. In some embodiments, a lower die 260 of the punching die is further provided below the turntable 110, and a hole corresponding to the punch 221 is formed in the lower die 260.

[0040] It should be understood that by setting the turntable 110, the relative position of the workpiece 500 and the punch 221 is adjusted to achieve automatic punching of multiple positions. Compared with the method of performing side punching at different positions of the workpiece 500 by adding a stamping component, the punching device of the present application is more integrated and more efficient in side punching at different positions of the same workpiece 500.

[0041] It is understandable that if Figure 2 As shown, the punching part 220 includes a clamping plate insert 222, a punch mounting block 223 and a stripping plate insert 224. An end of the clamping plate insert 222 close to the punch mounting block 223 is provided with an inclined guide surface 2221, and the punch 221 is arranged in the punch mounting block 223; the stripping plate insert 224 is elastically connected to the punch mounting block 223 so that one end of the punch 221 passes through the stripping plate insert 224 when the stripping plate insert 224 abuts against the punch mounting block 223, and the punch mounting block 223 and the stripping plate insert 224 are both arranged in the stripping plate insert 210, and the second driving member is used to drive the clamping plate insert 222 to move downward so as to drive the punch mounting block 223 and the stripping plate insert 224 to move obliquely in the stripping plate insert 210 through the inclined guide surface 2221.

[0042] Therefore, by providing the inclined guide surface 2221, when the clamping plate insert 222 moves downward in the vertical direction, the punch mounting block 223 and the stripping block 224 are subjected to an inclined force, so that the punch 221 moves linearly perpendicular to the position to be punched in the workpiece 500. When the clamping plate insert 222 moves upward and separates from the punch mounting block 223, since the stripping block 224 and the punch mounting block 223 are elastically connected, the punch mounting block 223 is reset under the action of elasticity, thereby driving the punch 221 to shrink in the stripping block 224.

[0043] It should be understood that, in some embodiments, the stripping block 224 and the punch mounting block 223 are elastically connected via a spring.

[0044] It should be understood that if Figure 6 As shown, in the mold opening state, the clamping plate insert 222 and the punch mounting block 223 and the stripping insert block 224 are spaced apart, and the punch mounting block 223 and the stripping insert block 224 are spaced apart. Figure 5 As shown, the clamping plate insert 222 abuts against the punch mounting block 223, and the stripping insert block 224 abuts against the punch mounting block 223. At this time, the spring connecting the stripping insert block 224 and the punch mounting block 223 is compressed.

[0045] Understandably, referring to Figures 3 to 6 As shown, the punching assembly 200 also includes a plurality of first templates 230 and a plurality of second templates 240, the clamping insert 222 is embedded in the first template 230; the stripping insert 210 is embedded in the second template 240, and the second driving member is used to drive the first template 230 to move up and down.

[0046] It should be understood that the service life of the plate insert 222 and the plate stripping insert 210 can be extended by providing the first template 230 and the second template 240 .

[0047] It should be understood that the present application does not limit the number of the first template 230 and the second template 240. In practical applications, different numbers of the first template 230 and the second template 240 can be set according to the structure of the stripping insert 210 and the clamping insert 222.

[0048] For example, Figure 3 and Figure 5 As shown, two of each of the first template 230 and the second template 240 are provided.

[0049] Understandably, referring to Figure 2 As shown, the punching assembly 200 further includes a limiting block 250 , which is arranged on the stripping insert 210 in a one-to-one correspondence with the punching portion 220 , and the punching portion 220 is provided with a limiting groove matching the corresponding limiting block 250 .

[0050] It should be understood that by separately providing the limiting block 250 , the structural requirements for the stripping insert 210 can be reduced, and at the same time, the punching assembly 200 can be assembled more conveniently.

[0051] It should be understood that the limiting block 250 is detachably connected to the stripping insert 210 .

[0052] Understandably, referring to Figure 1 and Figure 2 As shown, four punching portions 220 are provided, and the four punching portions 220 are evenly spaced and distributed around the axis of the rotating disk 110 .

[0053] It should be understood that by providing a plurality of punching portions 220 , side punching can be performed on a plurality of positions of the workpiece 500 at one time under the action of the second driving member, thereby further improving the punching efficiency.

[0054] It should be understood that the four punching portions 220 are evenly spaced and distributed, so that the turntable 110 can be used to perform side punching on multiple positions of the workpiece 500 at the same time.

[0055] Understandably, referring to Figure 1 and Figure 5 , Figure 6 As shown, the first driving member 120 is configured as a motor with a middle opening, and the punching device further includes a waste recovery device 300, which is located at the opening of the motor.

[0056] It should be understood that the waste recovery device 300 is used to suck away the waste generated after the side punching. Figures 4 to 6 As shown, the drawing only illustrates the suction pipe 310 of the waste recovery device 300, and the opening of the suction pipe 310 is arranged corresponding to the lower die of the punching die, so that the waste generated by punching can fall into the suction pipe 310. In other embodiments, the waste recovery device 300 further includes a driving member to improve the efficiency of waste recovery. This embodiment of the application is not limited to this.

[0057] Understandably, referring to Figures 3 to 6 As shown, the punching device also includes a punch body 410; the turntable assembly 100 also includes a turntable transmission column 130, the punch body 410 includes a support plate 411 and a bracket 412, the support plate 411 is located on the bracket 412, the turntable 110 is located above the support plate 411, the first driving member 120 is located below the support plate 411, the driving end of the first driving member 120 is connected to one end of the turntable transmission column 130, and the support plate 411 is provided with a movable groove corresponding to the turntable transmission column 130 one by one, and the other end of the turntable transmission column 130 is connected to the turntable 110 through the movable groove.

[0058] It should be understood that by providing the punch body 410 and the turntable transmission column 130 , the turntable assembly 100 can be integrated on the punch body 410 , so that the punching device has a smaller volume and a higher degree of integration.

[0059] Understandably, referring to Figures 3 to 6 As shown, the punching device also includes a punch cover plate 420. The punching assembly 200 is arranged on a side of the punch cover plate 420 close to the punch body 410. The punch cover plate 420 and the punch body 410 can be movably connected up and down. The second driving member is used to drive the punch cover plate 420 to move up and down so that the punching part 220 moves up and down.

[0060] Understandably, referring to Figures 3 to 6 As shown, a plurality of the turntable assemblies 100 and the punching assemblies 200 are provided, and the turntable assemblies 100 and the punching assemblies 200 are spaced apart and distributed along the length direction of the punching machine body 410 .

[0061] It should be understood that the punch cover plate 420 drives the multiple punching assemblies 200 simultaneously through a second driving member, thereby enabling the multiple punching assemblies 200 to work simultaneously and improving the punching efficiency.

[0062] Understandably, referring to Figure 1 As shown, the turntable assembly 100 also includes a plurality of auxiliary parts 140, which are distributed circumferentially along the turntable 110; one end of the auxiliary part 140 is connected to the punch body 410, and the other end of the auxiliary part 140 abuts against the turntable 110 and the other end of the auxiliary part 140 is set to an arc surface.

[0063] It should be understood that in some embodiments, the other end of the auxiliary part 140 is set as a ball so that the other end of the auxiliary part 140 forms an arc surface, which can reduce the friction between the turntable 110 and provide support force for the turntable 110, making the turntable 110 more stable, thereby further ensuring the effect of punching.

[0064] It should be understood that in some embodiments, the first driving member 120 can be configured as a driving member such as a stepping motor that can drive the turntable 110 to rotate, and the second driving member can be configured as a driving member such as a cylinder that can perform linear motion.

[0065] For example, Figures 1 to 6 As shown, the punching device of the present application works as follows:

[0066] First, the first driving member 120 drives the turntable 110 to move, so as to realize the rotation of the product. When the product rotates an angle, the turntable 110 stops, and the punch cover plate 420 moves down under the action of the second driving member, so that the punching part 220 moves down, thereby realizing the punching process. Specifically, the clamping plate insert 222 moves down with the punch cover plate 420, driving the fixed hole of the punch 221 to move down, so that the punch 221 moves down to realize the punching. After the clamping plate insert 222 moves up, under the action of elasticity, the punch mounting block 223 is reset first, thereby driving the stripping block 224 to reset, so that the stripping block 224 and the punch are separated from the product. Therefore, by setting the rotation angle of the turntable 110, after the first driving member 120 drives the turntable 110 to rotate a certain angle, the second driving member drives the punching part 220 to perform a lateral punching.

[0067] The above is a specific description of the preferred implementation of the present application, but the present application is not limited to the above-mentioned implementation mode. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the present application.
