Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a continuous stamping fixture for car door panels. Background Technology

[0002] During the production and processing of automotive door panels, stamping fixtures are typically used to perform multiple stamping processes, including blanking, punching, rounding, and cutting. Existing stamping fixtures require operators to reposition them after each stamping process. However, manual positioning by operators results in low positioning accuracy and stamping wobbling, leading to low stamping efficiency and high scrap rate of automotive door panels.

[0003] The prior art CN218015251U discloses a continuous stamping die for automotive door reinforcement panels. Before stamping, the sheet metal is fixed by abutting pressure to prevent it from shaking during stamping and affecting the stamping effect, thereby reducing the scrap rate of automotive door panels. By positioning the sheet metal to be stamped, the continuous stamping efficiency of the sheet metal can be improved, thereby reducing the wear caused by continuous stamping of the upper and lower die plates and increasing the service life of the upper and lower die plates.

[0004] However, when the aforementioned stamping device processes car door panels, multiple processes need to be completed on different stamping equipment. Therefore, the stamped parts need to be frequently transferred and clamped, which disrupts the continuity of the stamping process, reduces efficiency, and makes it difficult to ensure the uniformity of the processing datum during the transfer process. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] First embodiment:

[0021] Please see Figures 1 to 4 This utility model provides a continuous stamping fixture for car door panels, including a base 101, a transfer mechanism, a shearing mechanism, a punching mechanism, and a blanking mechanism. The transfer mechanism includes a guide rail 102, a moving plate 103, a position sensor 104, and a clamping component. The clamping component includes a clamping plate 105, a pressure plate 106, and a connecting spring 107. The shearing mechanism includes a support base 108, a first moving part 109, a second moving part 110, and a shearing part 111. The punching mechanism includes a mounting base 112, a third moving part 113, a fourth moving part 114, and a punching part 115. The blanking mechanism includes a fixed base 116, a fifth moving part 117, a sixth moving part 118, and a blanking part 119.

[0022] In this embodiment, the door panel is clamped and fixed by the transfer mechanism. After clamping and fixing, the door panel is transferred to the shearing mechanism for shearing and blanking. Then, it is transferred to the punching mechanism for punching the mounting holes. Finally, it is transferred to the blanking mechanism for shaping. The various mechanisms work together to ensure a continuous stamping process for the door panel, thus improving stamping efficiency. Simultaneously, it ensures the uniformity of the processing benchmark. This solves the problem of existing stamping devices where multiple processes need to be completed on different stamping machines, requiring frequent transfer and clamping of the stamped parts, disrupting the continuity of stamping, reducing efficiency, and making it difficult to ensure the uniformity of the processing benchmark during transfer.

[0023] The shearing mechanism, the punching mechanism, and the blanking mechanism are all located on the base 101 and arranged sequentially from left to right. There are two guide rails 102, which are symmetrically arranged on the front and rear sides of the base 101. The moving plate 103 is slidably arranged on the two guide rails 102. There are two position sensors 104, which are respectively arranged on the front and rear sides of the moving plate 103. The clamping member is located on the moving plate 103 and is used to clamp and fix the door panel. The moving plate 103 has a sliding groove 121, which cooperates with the guide rail 102 so that the moving plate 103 can slide laterally on the guide rail 102.

[0024] Secondly, there are two clamping plates 105, which are slidably disposed on the front and rear sides of the moving plate 103. Each clamping plate 105 has a slot 120, and a pressure plate 106 is movably disposed in each slot 120. The connecting spring 107 is disposed between the slot 120 and the pressure plate 106. The moving plate 103 has a sliding groove 121, and the clamping plates 105 have protrusions 122. The protrusions 122 and the sliding groove 121 are both U-shaped. The protrusions 122 are located in the sliding groove 121 and slide longitudinally within the sliding groove 121. The protrusions 122 of the two clamping plates 105 slide through the sliding groove 121. The two clamping plates 105 slide longitudinally within the grooves 121 of the movable plate 103, allowing them to move towards or away from each other, thus clamping and fixing the width of the door panel. The pressure plate 106 slides vertically within the slots 120 of the clamping plates 105 at corresponding positions, allowing the distance between the pressure plate 106 and the movable plate 103 to be adjusted, thus clamping and fixing the height of the door panel. At this time, the connecting spring 107 can extend and retract. Because the connecting spring 107 has a self-restoring function, it can buffer the vertical sliding of the pressure plate 106.

[0025] Furthermore, the lateral sliding of the moving plate 103 on the guide rail 102, the longitudinal sliding of the clamping plate 105 on the moving plate 103, and the vertical sliding of the pressure plate 106 within the slot 120 of the clamping plate 105 are all driven by the hydraulic telescopic rod 123.

[0026] Meanwhile, the support base 108 is disposed on the base 101, the first moving part 109 is disposed below the support base 108, the second moving part 110 is connected to the output end of the first moving part 109 and is located on the side of the first moving part 109 away from the support base 108, and both the first moving part 109 and the second moving part 110 are connected to the position sensor 104. The shearing part 111 is connected to the output end of the second moving part 110 and is located below the second moving part 110. The output end of the first moving part 109 is connected to the second moving part 110 and drives the second moving part 110 to move longitudinally below the support base 108, thereby driving the shearing part 111 to move longitudinally below the support base 108. The output end of the second moving part 110 is connected to the shearing part 111 and drives the shearing part 111 to move vertically below the support base 108.

[0027] Additionally, the mounting base 112 is disposed on the base 101, the third moving part 113 is disposed below the mounting base 112, the fourth moving part 114 is connected to the output end of the third moving part 113 and is located on the side of the third moving part 113 away from the mounting base 112, and both the third moving part 113 and the fourth moving part 114 are connected to the position sensor 104, the punching part 115 is connected to the output end of the fourth moving part 114 and is located below the fourth moving part 114, the output end of the third moving part 113 is connected to the fourth moving part 114 and drives the fourth moving part 114 to move longitudinally below the mounting base 112, thereby driving the punching part 115 to move longitudinally below the mounting base 112, and the output end of the fourth moving part 114 is connected to the punching part 115 and drives the punching part 115 to move vertically below the mounting base 112.

[0028] Finally, the fixed base 116 is disposed on the base 101, the fifth moving part 117 is disposed below the fixed base 116, the sixth moving part 118 is connected to the output end of the fifth moving part 117 and is located on the side of the fifth moving part 117 away from the fixed base 116, and both the fifth moving part 117 and the sixth moving part 118 are connected to the position sensor 104, the punching part 119 is connected to the output end of the sixth moving part 118 and is located below the sixth moving part 118, the output end of the fifth moving part 117 is connected to the sixth moving part 118 and drives the sixth moving part. 118 moves longitudinally below the fixed base 116, driving the punching part 119 to move longitudinally below the fixed base 116. The output end of the sixth moving part 118 is connected to the punching part 119 and drives the punching part 119 to move vertically below the fixed column. The position sensor can detect the position of the moving plate in real time and transmit the detection result to an external controller after detection, so that the external controller can control the start and stop of the first moving part 109, the second moving part 110, the third moving part 113, the fourth moving part 114, the fifth moving part 117 and the sixth moving part 118 according to the detection result.

[0029] When using a continuous stamping fixture for a car door panel in this embodiment, material preparation is first carried out, a suitable car door panel material is selected, and it is cut according to the design requirements to obtain a small sheet of car door panel suitable for stamping.

[0030] The material is cut and placed between the two clamping plates 105 on the moving plate 103. The hydraulic telescopic rod 123 at the corresponding position is activated, allowing the moving plate 103 to slide laterally on the guide rail 102, the clamping plates 105 to slide longitudinally on the moving plate 103, and the pressure plate 106 to slide vertically within the slot 120 of the clamping plate 105. When the clamping plates 105 slide longitudinally on the moving plate 103, the protrusions 122 of the two clamping plates 105 can slide longitudinally within the grooves 121 of the moving plate 103, thereby allowing the two clamping plates 105 to slide vertically. The plates can move towards or away from each other to clamp and fix the width of the small plate. The pressure plate 106 slides vertically within the slot 120 of the clamping plate 105, allowing the distance between the pressure plate 106 and the moving plate 103 to be adjusted, thus clamping and fixing the height of the small plate. At this time, the connecting spring 107 can extend and retract. Since the connecting spring 107 has a self-restoring function, it can buffer the vertical sliding of the pressure plate 106. By clamping and fixing the width and height of the small plate, the clamping and fixing of the small plate can be finally achieved.

[0031] Then, by sliding the moving plate 103 laterally on the guide rail 102, the small plate clamped and fixed on the moving plate 103 is moved laterally above the base 101 until the small plate is moved below the shearing part 111. At this time, the first moving part 109 is activated, so that the power output from the output end of the first moving part 109 drives the second moving part 110 to move longitudinally below the support seat 108, which in turn drives the shearing part 111 to move longitudinally below the support seat 108. The second moving part 110 is activated, so that the power output from the output end of the second moving part 110 drives the shearing part 111 to move vertically below the support seat 108. Combined with the longitudinal movement of the shearing part 111 below the support seat 108, the shearing part 111 can precisely cut the small plate to obtain the door panel raw material that meets the size requirements.

[0032] After punching and shearing, the moving plate 103 slides laterally on the guide rail 102, causing the small plate clamped and fixed on the moving plate 103 to move laterally above the base 101 until the small plate is moved below the punching part 115. At this time, the third moving part 113 is activated, so that the power output from the output end of the third moving part 113 drives the fourth moving part 114 to move longitudinally below the mounting base 112, causing the punching part 115 to move longitudinally below the mounting base 112. The fourth moving part 114 is activated, so that the power output from the output end of the fourth moving part 114 drives the punching part 115 to move vertically below the mounting base 112. Combined with the longitudinal movement of the punching part 115 below the mounting base 112, the punching part 115 can perform punching operations on the small plate, providing the necessary hole positions for subsequent assembly.

[0033] In the blanking process, after punching, the moving plate 103 slides laterally on the guide rail 102, causing the small plate clamped and fixed on the moving plate 103 to move laterally above the base 101 until the small plate is moved below the blanking part 119. At this time, the fifth moving part 117 is activated, so that the power output from the output end of the fifth moving part 117 drives the sixth moving part 118 to move longitudinally below the fixed base 116, causing the blanking part 119 to move longitudinally below the fixed base 116. The sixth moving part 118 is activated, so that the power output from the output end of the sixth moving part 118 drives the blanking part 119 to move vertically below the fixed base 116. Combined with the longitudinal movement of the blanking part 119 below the fixed base 116, the blanking part 119 can perform blanking on the small plate to make its shape conform to the design requirements.

[0034] In subsequent processing, after punching, the moving plate 103 is allowed to slide laterally on the guide rail 102, which drives the small plate clamped and fixed on the moving plate 103 to move laterally above the base 101, so as to transfer the raw material out and remove the small plate of the door panel and place it in the storage station for subsequent shaping, flanging and painting as needed.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
