Description

Technical Field

[0001] This invention relates to the field of cutting equipment, specifically to a cutting device and method for cutting spring sheet after welding. Background Technology

[0002] Currently, cutting dies are increasingly used in the market. Especially with the promotion of new energy vehicles, the demand for terminal crimping in new energy wiring harnesses is growing. In this vast market, traditional cutting dies almost entirely rely on manual labor for edge removal. After cutting slightly complex strips, manual removal is ineffective, leading to high labor intensity for workers and significant errors in welding accuracy. Manual removal cannot guarantee product consistency, resulting in unstable yield rates and limiting daily production capacity. Alternatively, using a single machine for inspection requires frequent machine changes, which is time-consuming and labor-intensive.

[0003] Therefore, it is necessary to provide a cutting device and cutting method for the spring sheet after welding. Summary of the Invention

[0004] The post-welding cutting device and cutting method provided by the present invention effectively solve the problems of low efficiency and low cutting accuracy in the existing post-welding cutting of springs.

[0005] The technical solution adopted in this invention is:

[0006] A spring sheet welding and cutting device includes a support, a clamping mechanism mounted on the support, and a cutting mechanism. The cutting mechanism includes a pressing component, an upper lifting component, and a lifting component for synchronously raising and lowering the pressing component and the upper lifting component. The lifting component includes a linear module mounted on the support along the Z-direction and a connecting plate mounted at the output end of the linear module. The pressing component includes a punch and a first slide cylinder mounted at the output end of the linear module. The upper lifting component includes a top head and a second slide cylinder mounted at the output end of the linear module. The punch includes a sheet metal body and several punches mounted at the lower end of the sheet metal body. The top head includes a base and top pins mounted on the base that correspond one-to-one with the punches.

[0007] Furthermore, the pressing mechanism includes a first linear guide rail disposed on the support along the Z direction and located at the upper end of the spring sheet flow direction, a pressure seat slidably disposed on the first linear guide rail, a first cylinder fixedly disposed on the support for driving the pressure seat to rise and fall, a second linear guide rail disposed on the support along the Z direction and located at the lower end of the spring sheet flow direction, a support seat slidably disposed on the second linear guide rail, and a second cylinder fixedly disposed on the support for driving the support seat to rise and fall.

[0008] Furthermore, the pressure base includes a first connecting frame disposed at the output end of the first cylinder and a lower pressing member disposed at the lower end of the first connecting frame. The first connecting frame and the lower pressing member form a first avoidance area for avoiding the lifting and lowering of the punch. The lower pressing member is provided with a first through hole for avoiding the punch needle. The support base includes a second connecting frame disposed at the output end of the second cylinder and a support plate disposed at the upper end of the second connecting frame. The support plate and the second connecting frame form a second avoidance area for avoiding the lifting and lowering of the top head. The support plate is provided with a second through hole for avoiding the ejector pin.

[0009] Furthermore, the pressing component includes several sliders, several positioning pins, several elastic blocks, and a cover plate disposed on the first connecting frame. The upper end of the elastic block is fixedly connected to the cover plate, and the slider is slidably connected to the lower end of the elastic block. The slider is provided with a groove extending along the Y direction. The positioning pin passes through the groove and is connected to the cover plate. The cross-section of the groove is an oblong hole. The first through hole is located between adjacent elastic blocks. The distance between the upper and lower ends of the oblong hole is greater than the diameter of the positioning pin, so that the slider can move up and down relative to the positioning pin.

[0010] Furthermore, the sheet metal body is provided with several air blowing channels, the air outlet of the air blowing channel is located on the lower end face of the sheet metal body, and the air blowing channel is used to blow away the waste material after it has been cut.

[0011] Furthermore, the second through hole is an oblique through hole.

[0012] The spring sheet post-weld cutting method uses a spring sheet post-weld cutting device. The spring sheet is pressed by a pressing mechanism. Then, the lower pressing component and the upper pressing component press the edge material from the upper and lower directions respectively. Then, the lifting component drives the upper pressing component and the lower pressing component to move up and down repeatedly to cut the edge material off the spring sheet.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, the spring sheet post-weld cutting device provided in the embodiments of this application includes a support 1, a pressing mechanism 2 and a cutting mechanism 3 disposed on the support 1. The cutting mechanism 3 includes a pressing component 31, an upper lifting component 32 and a lifting component 33 for driving the pressing component 31 and the upper lifting component 32 to move up and down synchronously. Figure 1 , Figure 2 and Figure 3As shown, the lifting assembly 33 includes a linear module 331 arranged along the Z direction on the support 1 and a connecting plate 332 arranged at the output end of the linear module 331. The pressing assembly 31 includes a punch 312 and a first slide cylinder 311 arranged at the output end of the linear module 331. The lifting assembly 32 includes a top head 322 and a second slide cylinder 321 arranged at the output end of the linear module 331. Figure 6 As shown, the punch 312 includes a sheet metal body 3121 and a plurality of punches 3122 disposed at the lower end of the sheet metal body 3121. Figure 7 As shown, the top head 322 includes a base 3221 and top pins 3222 disposed on the base 3221 that correspond one-to-one with the punches 3122.

[0025] In actual use, the pressing mechanism 2 presses the spring sheet, and then the pressing component 31 and the upper pressing component 32 press the edge material from the upper and lower directions respectively. Then, the lifting component 33 drives the upper pressing component 32 and the pressing component 31 to move up and down repeatedly, cutting the edge material off the spring sheet. Specifically, the first slide cylinder 311 drives the punch 312 to move down, and the second slide cylinder 321 drives the top head 322 to move up, so that the punch 3122 and the top pin 3222 contact the upper and lower end faces of the edge material to press it. Then, the linear module 331 drives the connecting plate 332 to move up and down, so that the first slide cylinder 311 and the second slide cylinder 321 drive the punch 312 and the top head 322 to move up and down synchronously, so that the edge material is separated from the spring sheet.

[0026] In the above design, the cutting mechanism 3 is designed to cut off the complex strip of the spring sheet in one go, improving product yield and cutting efficiency. The structural design and specific implementation of the lifting assembly 33, the upper lifting assembly 32, and the lower pressing assembly 31 can effectively achieve rapid and accurate separation of the edge material from the spring sheet, improving product yield and work efficiency.

[0027] Specifically: such as Figure 1 and Figure 2 As shown, the pressing mechanism 2 includes a first linear guide rail 21 arranged along the Z direction on the support 1 and located at the upper end of the spring sheet flow direction, a pressure seat 22 slidably arranged on the first linear guide rail 21, a first cylinder 23 fixedly arranged on the support 1 for driving the pressure seat 22 to rise and fall, a second linear guide rail 24 arranged along the Z direction on the support 1 and located at the lower end of the spring sheet flow direction, a support seat 25 slidably arranged on the second linear guide rail 24, and a second cylinder 26 fixedly arranged on the support 1 for driving the support seat 25 to rise and fall.

[0028] In actual use, when it is necessary to press the product, the pressure seat 22 is driven to slide down along the linear guide rail 21 by the first cylinder 23, and the support seat 25 is driven to slide up along the linear guide rail 24 by the second cylinder 26, so that the spring is pressed by the support seat 25 and the pressure seat 22.

[0029] In the above design, the structural design and specific implementation of the clamping mechanism 2 can effectively achieve rapid clamping of the spring sheet, ensure the stability of the spring sheet when the edge material is cut off, and improve the accuracy of edge material cutting.

[0030] Specifically: such as Figure 3 As shown, the pressure base 22 includes a first connecting frame 221 disposed at the output end of the first cylinder 23 and a lower pressing member 222 disposed at the lower end of the first connecting frame 221. The first connecting frame 221 and the lower pressing member 222 form a first avoidance area for the lifting and lowering of the punch 312. The lower pressing member 222 is provided with a first through hole for the avoidance of the punch 3122. The support base 25 includes a second connecting frame 251 disposed at the output end of the second cylinder 26 and a support plate 252 disposed at the upper end of the second connecting frame 251. The support plate 252 and the second connecting frame 251 form a second avoidance area for the lifting and lowering of the top head 322. Figure 8 As shown, the support plate 252 is provided with a second through hole 250 for avoiding the ejector pin 3222.

[0031] In actual use, the upper end face of the spring sheet is pressed by the pressing member 222, and the lower end face of the spring sheet is supported by the support plate 252. When the material is cut off, the punch 312 can move up and down in the first avoidance area, so that the punch 3122 passes through the first through hole and contacts the edge material. The top head 322 can move up and down in the second avoidance area, so that the top pin 3222 passes through the second through hole 250 and contacts the lower end face of the edge material.

[0032] In the above design, the structural design and specific implementation of the pressure seat 22 and the support seat 25 can effectively achieve rapid pressing of the spring sheet, and can effectively cooperate with the punch 312 and the top head 322 to cut off the edge material.

[0033] Specifically: such as Figure 3 , Figure 4 and Figure 5As shown, the pressing component 222 includes several sliders 2221, several positioning pins 2222, several elastic blocks 2223, and a cover plate 2224 disposed on the first connecting frame 221. The upper end of the elastic block 2223 is fixedly connected to the cover plate 2224, and the slider 2221 is slidably connected to the lower end of the elastic block 2223. The slider 2221 is provided with a groove extending in the Y direction. The positioning pin 2222 passes through the groove and is connected to the cover plate 2224. The cross-section of the groove is an oblong hole. The first through hole is located between adjacent elastic blocks 2223. The distance between the upper and lower ends of the oblong hole is greater than the diameter of the positioning pin 2222, so that the slider 2221 can move up and down relative to the positioning pin 2222.

[0034] In actual use, several sliding blocks 2221 press down on several welding positions of the spring piece at their lower ends. During the pressing process, the elastic block 2223 deforms. During the pressing process, the sliding blocks 2221 move upward relative to the positioning pin 2222.

[0035] In the above design, the structural design and specific implementation of the pressing member 222 can effectively press the spring sheet, and can effectively cooperate with the punch 312 and the top head 322 to cut off the edge material of the spring sheet.

[0036] Specifically: such as Figure 6 As shown, the sheet metal body 3121 is provided with a plurality of air blowing channels 101. The air outlet of the air blowing channel 101 is located on the lower end face of the sheet metal body 3121. The air blowing channel 101 is used to blow away the waste material after it has been cut.

[0037] In actual use, the cut-off edge material is blown away by the air blowing channel 101 and flows away through the second through hole 250.

[0038] In the above design, the structural design and specific implementation of the air blowing channel 101 can effectively achieve rapid blowing of the edge material.

[0039] Specifically: such as Figure 8 As shown, the second through hole 250 is an oblique through hole.

[0040] In actual use, the cut-off edge material falls off along the No. 2 through hole 250.

[0041] In the above design, the angled design of the No. 2 through hole 250 facilitates material unloading.

[0042] The spring sheet post-weld cutting method uses a spring sheet post-weld cutting device. The spring sheet is pressed by the pressing mechanism 2. Then, the lower pressing component 31 and the upper pressing component 32 press the edge material from the upper and lower directions of the spring sheet respectively. Then, the lifting component 33 drives the upper pressing component 32 and the lower pressing component 31 to move up and down repeatedly to cut the edge material off the spring sheet.

[0043] In further detail, it should be understood that the above description 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 within the protection scope of the present invention.
