If a certain posture changes, the directional indication will also change accordingly.

[0021] Reference Figures 1-14As shown in the figure, the present invention provides a punching device for spring sheet processing, including a processing machine tool 1, a spring sheet plate 8, and a PLC controller 4. A hydraulic rod 2 is arranged on the processing machine tool 1, and an upper die 10 is installed at the telescopic end of the hydraulic rod 2. An assembly groove 11 is opened on the support surface of the processing machine tool 1, and a power component 9 is installed on the inner cavity side wall of the assembly groove 11. The processing machine tool 1 is fixedly provided with a blanking frame 7 through two connecting rods. A collection box 5 is installed on the bottom surface of the inner cavity of the processing machine tool 1. An adjustment component 12 is arranged between the collection box 5 and the power component 9. A blanking component 13 is arranged on the processing machine tool 1. A limiting frame 15 is installed on the end face of the processing machine tool 1; Among them, the PLC controller 4 controls the process of the equipment in the device as follows: The PLC controller 4 controls the number of rotation circles of the power output shaft of the forward stepping motor 903, so as to control the distance that the moving block 904, the connecting frame 905, the resisting plate 906, and the spring sheet plate 8 are pushed. After completion, it controls the hydraulic rod 2 to drive the upper die 10 to perform stamping; Subsequently, it controls the power output shaft of the stepping motor 903 to rotate in the reverse direction by a certain number of circles, so that the moving block 904, the connecting frame 905, and the resisting plate 906 are reset. After resetting to the original position, it still continues to rotate, so as to drive the operation of the blanking component 13 and the adjustment component 12, thereby realizing automatic material distribution; After completing the above steps, the PLC controller 4 controls the stepping motor 903 to rotate forward, so that the moving block 904, the connecting frame 905, and the resisting plate 906 return to the initial position, realizing a complete operation process. And the programming control of the PLC controller 4 to control the operation between different electrical equipment belongs to the prior art well-known to those skilled in the art, and will not be described in detail again; The power component 9 includes an installation frame 901.

A resisting plate 906 is installed on the side wall of the connecting frame 905; Among them, the connecting frame 905 is designed in an "L" shape to improve space utilization; The spring sheet plates 8 are stacked and slide in the inner cavity of the blanking frame 7. A gap is left between the blanking frame 7 and the end face of the processing machine tool 1. The height of the gap is greater than the thickness of one spring sheet plate 8 and less than the thickness of two spring sheet plates 8; In this example: During the production process, the stepping motor 903 is started to drive the threaded rod 902 to rotate, thereby adjusting the positions of the moving block 904, the connecting frame 905, and the abutting plate 906, so that the abutting plate 906 pushes the spring sheet 8 between the blanking frame 7 and the processing machine tool 1 to move. Under the limiting action of the limiting frame 15, the spring sheet 8 is smoothly pushed below the hydraulic rod 2 and the upper die 10; Subsequently, the stepping motor 903 is controlled to rotate in the reverse direction to drive the moving block 904, the connecting frame 905, and the abutting plate 906 to reset. When pushing the previous spring sheet 8, the end face of the abutting plate 906 is always in contact with the bottom surface of the next spring sheet 8 to be processed, avoiding the abutting plate 906 from pushing the next spring sheet 8 to be processed in the reverse direction when resetting. Subsequently, the hydraulic rod 2 is started to drive the upper die 10 to press down, and the spring sheet 8 is processed by the cooperation of the upper die 10 and the lower die 137, and the debris generated by the stamping falls along the chute 3 and the material guide pipe 16, and under the guiding action of the turning plate 123, it enters one side of the collection box 5.

[0022] In a further embodiment, referring to Figures 1-7 , a chute 3 is opened on the end face of the processing machine tool 1, and an installation groove 14 is opened on the side wall of the chute 3. The installation groove 14 communicates with the assembly groove 11, and the blanking assembly 13 is cooperatively installed between the installation groove 14 and the moving block 904; The blanking assembly 13 includes a moving frame 131.

At this time, the moving block 904 pulls the second connecting rope 136, and the second connecting rope 136 changes direction through the rotating wheel 3 134, thereby pulling the moving frame 131 to move in the direction of the installation slot 14; At this time, the moving frame 131 will drive the lower mold 137 to slide in the installation groove 14 and the blanking assembly 13 respectively. At this time, the spring sheet body 18 will be blocked by the limit frame 15, and the lower mold 137 will be separated from the spring sheet body 18, so as to facilitate the spring sheet body 18 to be discharged along the slide groove 3 and the guide tube 16.

[0023] In a further embodiment, referring to Figures 1-13 The adjustment component 12 includes a limit frame 1213 and an isolation plate 121, and the isolation plate 121 is installed in the middle of the bottom surface of the inner cavity of the collection box 5; A through slot 1216 is provided on the end surface of the processing machine tool 1, and a limit frame 1213 is sequentially installed in the inner cavity of the through slot 1216 from top to bottom. A lifting block 1216 is slidably installed between the two limit frames 1213, and an arc block 1217 is installed on the end surface of the lifting block 1216. A limit frame 1214 is installed on the side wall of the lifting block 1216. The limit frame 1214 slides between the two limit frames 1213. Damping springs 1215 are symmetrically installed on the bottom surface of the limit frame 1214. The two damping springs 1215 are connected to one limit frame 1213 at a side away from the limit frame 1214. A mounting seat 1210 is installed on the top surface of the inner cavity of the processing machine tool 1, and a second rotating wheel 1211 is rotatably installed on the mounting seat 1210. A second toggle rod 1212 is arranged on the side wall of the second rotating wheel 1211, and a first toggle rod 126 is arranged on the side wall of the second rotating wheel 1211; A fixing rod 125 is installed on the top surface of the inner cavity of the processing machine tool 1, a connecting shaft 127 is installed on the side wall of the fixing rod 125, a protective plate 1219 is symmetrically installed on the outer wall of the connecting shaft 127, a rotating wheel 128 is rotatably installed on the outer wall of the connecting shaft 127, the rotating wheel 128 is located between two protective plates 1219, and an arc plate 129 is arranged between the two protective plates 1219; A connecting rope 124 is inserted between the protective plate 1219, the rotating wheel 128 and the arc plate 129, one end of the connecting rope 124 is connected to the toggle rod 126, and the other end of the connecting rope 124 is connected to the flip plate 123; The isolation plate 121 is in a "concave" shape; A connecting shaft two 1218 is rotatably arranged on the partition plate 121, the turnover plate 123 is fixedly sleeved on the outer wall of the connecting shaft two 1218, torsion springs 122 are symmetrically sleeved on the outer wall of the connecting shaft two 1218, one end of the torsion spring 122 is connected to the adjusting assembly 12, the other end of the torsion spring 122 is connected to the inner wall of the partition plate 121, and the torsion spring 122 is used to drive the turnover plate 123 to reset; A material guiding pipe 16 is installed on the top surface of the inner cavity of the processing machine tool 1, the material guiding pipe 16 is communicated with the sliding groove 3, and through grooves two 17 are respectively arranged on the front and rear outer walls of the material guiding pipe 16; In this embodiment: when the moving block 904, the connecting frame 905 and the abutting plate 906 are far away from the hydraulic rod 2, the abutting plate 906 will press the pressurizing arc block 1217, so as to press the arc block 1217 and the lifting block 1216 downward. Subsequently, the lifting block 1216 will press the shifting rod two 1212 downward, and the shifting rod two 1212 will drive the rotating wheel two 1211 to rotate, thereby driving the rotation of the shifting rod one 126. The rotation of the shifting rod one 126 will pull the turnover plate 123 to turn over through the connecting rope one 124, so as to change the falling direction of the spring piece body 18 falling from the sliding groove 3 and the material guiding pipe 16, so that the spring piece body 18 falls to the other side of the collection box 5, realizing the convenient separation and storage of the waste materials and finished products generated by stamping the spring piece plate 8, achieving the effects of automatic classification, improving the processing efficiency and reducing manual intervention; Furthermore, the distance from the shifting rod one 126 to the rotating wheel two 1211 should be greater than the distance from the shifting rod two 1212 to the rotating wheel two 1211, so as to facilitate the longer moving distance of the end of the shifting rod one 126 when the lifting block 1216 pushes the shifting rod two 1212 to rotate; Similarly, the connection position of the connecting rope one 124 and the turnover plate 123 should be close to the connection position of the turnover plate 123 and the connecting shaft two 1218, which is convenient for the efficient turnover of the turnover plate 123; Before and after the turnover plate 123 is subjected to the pulling force of the connecting rope one 124, the inclination direction of the turnover plate 123 changes, so as to facilitate the classified storage of the waste materials and finished products generated by stamping.

[0024] A spring piece applied to a thermostat manufactured by a spring piece processing punching device, including a spring piece body 18, the two sides of the spring piece body 18 are designed in a widened arc shape, a riveting hole 19 is arranged on the top surface of the spring piece body 18, and an arc groove 20 is arranged around the riveting hole 19 of the spring piece body 18; In this example, on the basis of the design of the straight-strip spring piece, the areas of the two wings of the spring piece are widened to enhance the current-carrying and heat dissipation capabilities; an arc-shaped groove is arranged around the riveting hole to increase the length of the movable arm; the material consumption is saved compared with the traditional bent spring piece; compared with the ordinary straight-strip spring piece, it has a greater current-carrying capacity and better heat dissipation effect, avoiding the thermal failure of the spring piece, and a longer effective length of the movable arm, avoiding the mechanical fatigue damage of the spring piece when ensuring that the electric contact has enough opening clearance, and greatly extending the service life of the product.

[0025] The working principle of the present invention is as follows: Before the device is used, the electrical equipment in the device is first powered on, and the spring piece plates 8 are stacked and placed in the blanking frame 7 and put into production; During the production process, the stepping motor 903 is started to drive the threaded rod 902 to rotate, thereby adjusting the positions of the moving block 904, the connecting frame 905 and the abutting plate 906, so that the abutting plate 906 pushes the spring piece plates 8 between the blanking frame 7 and the processing machine tool 1 to move. Under the limiting action of the limiting frame 15, the spring piece plates 8 are smoothly pushed below the hydraulic rod 2 and the upper die 10; Subsequently, the stepping motor 903 is controlled to rotate in the reverse direction to drive the moving block 904, the connecting frame 905 and the abutting plate 906 to reset. Then the hydraulic rod 2 is started to drive the upper die 10 to press down, and the spring piece plates 8 are processed by using the cooperation of the upper die 10 and the lower die 137, and the chips generated by the stamping fall along the chute 3 and the material guide pipe 16, and enter one side of the collection box 5 under the guiding action of the turning plate 123; When the stepping motor 903 drives the moving block 904 to reset to the initial point and waits for the spring piece plates 8 to be stamped, the stepping motor 903 is started to continue rotating in the reverse direction to drive the moving block 904 to continue moving away from the hydraulic rod 2. At this time, the moving block 904 pulls the second connecting rope 136, and the second connecting rope 136 changes the direction through the third rotating wheel 134, so as to pull the moving frame 131 to move towards the installation groove 14; At this time, the moving frame 131 will drive the lower die 137 to slide in the installation groove 14 and the blanking assembly 13 respectively. At this time, under the blocking of the limiting frame 15, the lower die 137 will be separated from the spring piece body 18, so as to facilitate the spring piece body 18 to be discharged along the chute 3 and the material guide pipe 16; At the same time, when the moving block 904, the connecting frame 905 and the contact plate 906 are away from the hydraulic rod 2, the contact plate 906 will pressurize the arc block 1217, thereby pressing the arc block 1217 and the lifting block 1216 downward, and then the lifting block 1216 will press the toggle rod 2 1212 downward, and the toggle rod 2 1212 drives the rotating wheel 2 1211 to rotate, thereby driving the rotation of the toggle rod 1 126, and the rotation of the toggle rod 126 will pull the flip plate 123 to flip through the connecting rope 124, thereby changing the falling direction of the spring sheet body 18 falling from the slide 3 and the guide tube 16, so that the spring sheet body 18 falls to the other side of the collection box 5, so as to facilitate the separation and storage of the waste and finished products generated by the stamping spring sheet plate 8, so as to achieve the effect of automatic classification, improve processing efficiency and reduce manual intervention.
