The spring sheet processing and punching equipment is an important equipment used for spring sheet processing and forming.

[0003] Patent publication number CN212598282U describes a rapid prototyping device for producing spring sheets. The upper and lower molds are installed separately, the material is placed on the lower mold, and the punching machine is started to press the upper mold downward. The material is punched and deformed into the desired shape between the lower and upper molds. The punching needle moves downward to contact the material, then moves into the groove to punch holes in the raw material.

DETAILED DESCRIPTION

[0043] The following will be combined with the Figure 1 To the attached Figure 14 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0044] It should be noted that if there are any directions involved in the embodiments of the present invention, they shall be based on the directions shown in the drawings, such as front and back. Figure 1 The specific Figure 1 The left side is the front, Figure 1 The right side is the back; at the same time Figure 2 As shown in the figure, the left-right direction is roughly the horizontal direction, and the up-down direction shown in the figure is the vertical direction. If a specific posture changes, the directional indication will also change accordingly.

[0045] Reference Figures 1-14As shown, the present invention provides a spring sheet processing and punching device, including a processing machine tool 1, a spring sheet plate 8 and a PLC controller 4. The processing machine tool 1 is provided with a hydraulic rod 2, and an upper mold 10 is installed at the telescopic end of the hydraulic rod 2. The supporting surface of the processing machine tool 1 is provided with an assembly groove 11, and a power component 9 is installed on the side wall of the inner cavity of the assembly groove 11. The processing machine tool 1 is fixed 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 provided between the collection box 5 and the power component 9. A blanking component 13 is provided on the processing machine tool 1, and a limit frame 15 is installed on the end face of the processing machine tool 1.

[0046] The PLC controller 4 controls the process of the equipment in the device as follows: the PLC controller 4 controls the number of revolutions of the power output shaft of the forward stepping motor 903, thereby controlling the distance that the moving block 904, the connecting frame 905, the contact plate 906, and the spring plate 8 are pushed. After completion, the PLC controller 4 controls the hydraulic rod 2 to drive the upper die 10 to perform stamping;

[0047] Then, the power output shaft of the stepping motor 903 is controlled to rotate in the opposite direction for a certain number of circles, so that the moving block 904, the connecting frame 905 and the contact plate 906 are reset. After resetting to the original position, they continue to rotate, thereby driving the operation of the unloading assembly 13 and the adjusting assembly 12, thereby realizing automatic material separation;

[0048] 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 contact plate 906 return to their initial positions, thus completing the complete operation process. The programming control of the operation between different electrical devices by the above-mentioned PLC controller 4 belongs to the existing technology well known to those skilled in the art, and will not be described in detail again.

[0049] The power member 9 includes a mounting frame 901, which is mounted on the side wall of the inner cavity of the assembly slot 11. A stepper motor 903 is mounted on the outer wall of the mounting frame 901. A threaded rod 902 is rotatably provided in the inner cavity of the mounting frame 901. The power output shaft of the stepper motor 903 passes through the outer wall of the mounting frame 901 and is connected to the threaded rod 902. A moving block 904 is threadedly connected to the threaded rod 902. A connecting frame 905 is mounted on the top surface of the moving block 904. A contact plate 906 is mounted on the side wall of the connecting frame 905.

[0050] The connecting frame 905 is designed in an "L" shape to improve space utilization;

[0051] The spring sheets 8 are stacked and slid in the inner cavity of the blanking frame 7. A gap is left between the blanking frame 7 and the end surface of the processing machine 1. The height of the gap is greater than the thickness of one spring sheet 8 and less than the thickness of two spring sheets 8.

[0052] In this example, during the production process, the stepper motor 903 is started to rotate the threaded rod 902, thereby adjusting the positions of the moving block 904, the connecting frame 905, and the contact plate 906. The contact plate 906 pushes the spring plate 8 between the blanking frame 7 and the processing machine 1 to move. Under the limiting action of the limiting frame 15, the spring plate 8 is smoothly pushed to the bottom of the hydraulic rod 2 and the upper mold 10.

[0053] Then, the stepper motor 903 is controlled to rotate in the opposite direction, driving the moving block 904, the connecting frame 905 and the contact plate 906 to reset. When pushing the previous spring sheet 8, the end face of the contact plate 906 is always in contact with the bottom face of the next spring sheet 8 to be processed, thereby preventing the contact plate 906 from pushing the next spring sheet 8 to be processed in the opposite direction when resetting. Then, the hydraulic rod 2 is started to drive the upper mold 10 to press down, and the spring sheet 8 is punched by the cooperation of the upper mold 10 and the lower mold 137 to realize the processing of the spring sheet 8. The debris generated by the stamping falls along the chute 3 and the guide tube 16, and enters one side of the collection box 5 under the diversion action of the flip plate 123.

[0054] In a further embodiment, referring to Figure 1-Figure 7 The end surface of the processing machine tool 1 is provided with a slide groove 3, and the side wall of the slide groove 3 is provided with a mounting groove 14, the mounting groove 14 is connected to the assembly groove 11, and the blanking assembly 13 is installed between the mounting groove 14 and the moving block 904;

[0055] The blanking assembly 13 includes a movable frame 131, which is slidably mounted between the mounting groove 14 and the assembly groove 11. A second protective plate 133 is mounted on the bottom surface of the inner cavity of the mounting groove 14. The second protective plate 133 and the movable frame 131 are in contact with each other. A third rotating wheel 134 is provided between the second protective plate 133 and the movable frame 131.

[0056] A third connecting shaft 132 is mounted on the inner wall of the assembly slot 11 on which the mounting frame 901 is mounted. Two second protective plates 133 are mounted on the outer wall of the third connecting shaft 132. A third rotating wheel 134 is rotatably mounted on the outer wall of the third connecting shaft 132. The third rotating wheel 134 is located between the two second protective plates 133. A second curved plate 135 is disposed between the two second protective plates 133.

[0057] The movable frame 131 is located inside the mounting groove 14 and a lower mold 137 is installed on one side thereof;

[0058] The movable frame 131 is provided with a second connecting rope 136 on one side outside the mounting groove 14. The second connecting rope 136 is inserted between the second protective plate 133, the third rotating wheel 134 and the second curved plate 135. The side of the second connecting rope 136 away from the movable frame 131 is connected to the movable block 904.

[0059] In this embodiment, after the stepper motor 903 drives the moving block 904 to return to the initial point and waits for the spring sheet 8 to be stamped, the stepper motor 903 is started to continue to rotate in the reverse direction, driving the moving block 904 to continue to move 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 direction through the rotating wheel 3 134, thereby pulling the moving frame 131 to move toward the installation slot 14.

[0060] At this time, the movable frame 131 will drive the lower mold 137 to slide in the mounting groove 14 and the blanking assembly 13 respectively. At this time, the spring sheet body 18 is blocked by the limit frame 15, and the lower mold 137 will be separated from the spring sheet body 18, thereby facilitating the spring sheet body 18 to be discharged along the slide groove 3 and the guide tube 16.

[0061] In a further embodiment, referring to Figures 1-13 The adjustment component 12 includes a limit frame 1213 and an isolation plate 121. The isolation plate 121 is installed in the middle of the bottom surface of the inner cavity of the collection box 5;

[0062] A through slot 1216 is provided on the end surface of the processing machine tool 1. A limit frame 1213 is sequentially installed in the inner cavity of the through slot 1213 from top to bottom. A lifting block 1216 is slidably installed between the two limit frames 1213. An arc block 1217 is installed on the end surface of the lifting block 1216. A limit frame 214 is installed on the side wall of the lifting block 1216. The limit frame 214 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 of the limit frames 1213 on the side away from the limit frame 214.

[0063] A mounting seat 1210 is mounted on the top surface of the inner cavity of the processing machine tool 1. A second rotating wheel 1211 is rotatably mounted on the mounting seat 1210. A second toggle lever 1212 is mounted on the side wall of the second rotating wheel 1211. A first toggle lever 126 is mounted on the side wall of the second rotating wheel 1211.

[0064] A fixing rod 125 is mounted on the top surface of the inner cavity of the processing machine tool 1. A connecting shaft 127 is mounted on the side wall of the fixing rod 125. A protective plate 1219 is symmetrically mounted on the outer wall of the connecting shaft 127. A rotating wheel 128 is rotatably mounted on the outer wall of the connecting shaft 127. The rotating wheel 128 is located between two protective plates 1219. An arc plate 129 is disposed between the two protective plates 1219.

[0065] A connecting rope 124 is inserted between the protective plate 1219, the rotating wheel 128 and the curved 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.

[0066] The isolation plate 121 is in a "concave" shape;

[0067] A second connecting shaft 1218 is rotatably provided on the isolation plate 121. The flip plate 123 is fixedly sleeved on the outer wall of the second connecting shaft 1218. A torsion spring 122 is symmetrically sleeved on the outer wall of the second connecting shaft 1218. One end of the torsion spring 122 is connected to the adjustment assembly 12, and the other end of the torsion spring 122 is connected to the inner wall of the isolation plate 121. The torsion spring 122 is used to drive the flip plate 123 to reset.

[0068] A guide tube 16 is installed on the top surface of the inner cavity of the processing machine tool 1. The guide tube 16 is connected to the chute 3. The outer walls of the guide tube 16 on both sides are respectively provided with through grooves 17.

[0069] In this embodiment: 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 chute 3 and the guide tube 16, so that the spring sheet body 18 falls to the other side of the collection box 5, thereby facilitating the separation and storage of the waste and finished products generated by the stamping spring sheet plate 8, achieving the effect of automated classification, improving processing efficiency, and reducing manual intervention;

[0070] Furthermore, the distance between the toggle rod 126 and the rotating wheel 2 1211 should be greater than the distance between the toggle rod 2 1212 and the rotating wheel 2 1211 , so that the end of the toggle rod 126 moves a longer distance when the lifting block 1216 pushes the toggle rod 2 1212 to rotate;

[0071] Similarly, the connection point between the first connecting rope 124 and the flip plate 123 should be close to the connection point between the flip plate 123 and the second connecting shaft 1218 to facilitate efficient flipping of the flip plate 123.

[0072] Before and after the turning plate 123 is pulled by the connecting rope 124, the tilt of the turning plate 123 changes, thereby facilitating the classification and storage of waste materials and finished products produced by stamping.

[0073] A spring sheet used in a thermostat, manufactured by a spring sheet processing and punching device, includes a spring sheet body 18, both sides of the spring sheet body 18 are designed to be widened arc-shaped, a rivet hole 19 is formed on the top surface of the spring sheet body 18, and an arc groove 20 is formed on the spring sheet body 18 around the rivet hole 19;

[0074] In this example, based on the design of a straight spring leaf, the area of ​​the two wings of the spring leaf is widened to enhance the current carrying and heat dissipation capabilities; an arc groove is provided on the periphery of the rivet hole to increase the length of the movable arm; compared with the traditional bent spring leaf, the spring leaf saves material; compared with the ordinary straight spring leaf, the spring leaf has a greater current carrying capacity and better heat dissipation effect, avoiding thermal failure of the spring leaf; and the longer effective length of the movable arm avoids mechanical fatigue damage to the spring leaf while ensuring that the electrical contacts have sufficient opening gap, thereby greatly extending the service life of the product.

[0075] 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 sheet materials 8 are stacked and placed in the blanking frame 7 and put into production;

[0076] During the production process, the stepper 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 contact plate 906, so that the contact plate 906 pushes the spring plate 8 between the blanking frame 7 and the processing machine 1 to move. Under the limiting action of the limiting frame 15, the spring plate 8 is smoothly pushed to the bottom of the hydraulic rod 2 and the upper mold 10;

[0077] Then, the stepper motor 903 is controlled to rotate in the opposite direction, driving the moving block 904, the connecting frame 905 and the contact plate 906 to reset. Then, the hydraulic rod 2 is activated to drive the upper mold 10 to press downward. The spring sheet 8 is punched by the cooperation of the upper mold 10 and the lower mold 137, thereby completing the processing of the spring sheet 8. The debris generated by the punching falls along the chute 3 and the guide tube 16, and enters one side of the collection box 5 under the guidance of the flip plate 123.

[0078] When the stepper motor 903 drives the moving block 904 to return to the initial point and waits for the spring sheet 8 to be stamped, the stepper motor 903 is started to continue to rotate in the reverse direction, driving the moving block 904 to move further 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 direction through the rotating wheel 3 134, thereby pulling the moving frame 131 to move toward the installation slot 14.

[0079] At this time, the movable frame 131 will drive the lower mold 137 to slide in the mounting groove 14 and the blanking assembly 13 respectively. At this time, the spring sheet body 18 is blocked by the limiting frame 15, and the lower mold 137 will be separated from the spring sheet body 18, so that the spring sheet body 18 can be easily discharged along the chute 3 and the guide tube 16.

[0080] 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 chute 3 and the guide tube 16, so that the spring sheet body 18 falls to the other side of the collection box 5, thereby facilitating the separation and storage of the waste and finished products generated by the stamping spring sheet plate 8, achieving the effect of automated classification, improving processing efficiency, and reducing manual intervention.

[0081] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention.
