Description

Technical Field

[0001] This utility model relates to the field of stamping molds for inner door sill connecting plates, and specifically to a stamping mold for the rear connecting plate of the inner door sill. Background Technology

[0002] In the manufacturing process of automobile body-in-white, the rear connecting plate of the sill inner panel is one of the important structural components in the sill area. It is usually used to connect the sill inner panel with key components such as the rear longitudinal beam and the rear wheel arch. Its structure is complex and has high stress requirements. It is a typical high-strength steel plate stamping part. In order to meet the high precision and high stability production requirements of this type of plate, special stamping dies are often used for forming, punching and trimming operations.

[0003] In existing stamping dies, the precise positioning of sheet metal within the die cavity is usually achieved by setting fixed locating pins and limit blocks. However, due to the hardness and elasticity of high-strength steel sheet metal, the edges of the sheet metal often cannot accurately align with all the locating pins at once during feeding, which can easily lead to mispositioning or jamming. To ensure that the sheet metal fully contacts all locating elements, it is often necessary to repeatedly shake or adjust the sheet metal to achieve a suitable positioning state, resulting in reduced feeding efficiency.

[0004] Based on this, this utility model designs a stamping die for the rear connecting plate of the sill inner panel to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stamping die for the rear connecting plate of the inner sill plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stamping die for a sill inner panel rear connecting plate includes a base, a lower die and an upper die on the top of the base, the lower die being fixedly connected to the base, the upper die being located on top of the lower die, and a feeding and sorting mechanism for quickly feeding and sorting sheet metal. The feeding and sorting mechanism is located on one side of the lower die, wherein the feeding and sorting mechanism includes a material-fixing frame on both sides of the top of the lower die, and a sorting component is provided on one side of each of the two material-fixing frames on both sides. A replacement component is provided between the material-fixing frame and the sorting component.

[0008] Furthermore, the finishing assembly includes two support plates that are slidably mounted on the surface of the lower mold, two material fixing frames on both sides that are respectively located on the surfaces of the two support plates, a receiving plate that is fixedly mounted on the bottom of the support plate, an induction pressure plate that is fixedly mounted inside the receiving plate, and an air pump that is fixedly mounted on the surface of the base.

[0009] Furthermore, piston plates are fixedly installed at the bottom of both receiving plates. The piston plates are slidably installed inside the lower mold. A regulating valve is fixedly installed at the output end of the air pump. A first diverter pipe and a second diverter pipe are fixedly installed on both sides of the regulating valve, respectively. The two output ends of the first diverter pipe are located on the adjacent side of the two piston plates, and the two output ends of the second diverter pipe are located on the opposite side of the two piston plates.

[0010] Furthermore, the receiving plate is slidably installed inside the lower mold, and the induction pressure plate is embedded on the surface of the receiving plate.

[0011] Furthermore, elastic sealing strips are fixedly installed on both sides of the support plate, and the two elastic sealing strips on opposite sides are fixedly connected to the lower mold.

[0012] Furthermore, the multiple positioning frames are located at the four corners of the sheet metal, and the tops of the multiple positioning frames are all set as bevels.

[0013] Furthermore, the replacement component includes a mounting plate fixedly installed on one side of the material frame, the mounting plate being fixedly connected to the surface of the support plate.

[0014] Furthermore, a screw is rotatably mounted on the surface of the mounting plate, and two screw holes are opened on the surface of the support plate, with the screw threadedly connected to the adjacent screw holes. Beneficial effects

[0015] The guide frames are located on both sides of the lower mold to define the placement range of the sheet metal and provide lateral positioning. The aligning assembly can cause the guide frames to wobble slightly, guiding the sheet metal into place quickly. The replacement assembly allows for quick replacement of different models of guide frames without adjusting the main mold structure, improving the mold's adaptability to multiple specifications.

[0016] The material frame can be quickly installed or removed from the support plate via the mounting plate. When changing to different models of material frames, the installation or release operation can be completed simply by rotating the screw, eliminating tedious disassembly steps and improving replacement efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5A stamping die for a sill inner panel rear connecting plate includes a base 100, a lower die 200 and an upper die 210 disposed on the top of the base 100, the lower die 200 being fixedly connected to the base 100, and the upper die 210 being located on top of the lower die 200; a feeding and sorting mechanism 300, used for quickly feeding and sorting sheet metal, is disposed on one side of the lower die 200; wherein, the feeding and sorting mechanism 300 includes a material-fixing frame 310 disposed on both sides of the top of the lower die 200, a sorting component 320 disposed on one side of each of the two material-fixing frames 310, and a replacement component 330 disposed between the material-fixing frame 310 and the sorting component 320.

[0028] In this embodiment of the utility model, the material positioning frame 310 is set on both sides of the lower mold 200 to limit the placement range of the sheet material and provide a lateral positioning boundary for the blank. The sorting component 320 can slightly shake the corresponding two material positioning frames 310 so that the sheet material can quickly slide into the designated area under its guidance, so that the blank can be quickly positioned. The replacement component 330 is set between the material positioning frame 310 and the sorting component 320, so that the material positioning frame 310 can be quickly replaced according to the different models or sizes of the sill inner plate and the connecting plate behind it, without adjusting the main mold structure, thus improving the mold's compatibility with multi-specification parts.

[0029] It should be noted that the existing sill plate rear connecting plate stamping die typically includes basic components such as base 100, upper die 210, lower die 200, guide pillars and guide sleeves, positioning pins, limit blocks, and pressing mechanism. The material fixing frame 310 and the sorting component 320, as part of the material feeding and sorting mechanism 300, are set on one side of the lower die 200 and located outside the mold cavity. They do not interfere with the normal mold closing and mold opening paths of the upper die 210 and the lower die 200, nor do they interfere with the forming surface in the stamping area. The material fixing frame 310 and the sorting component 320 are modularly connected by replacing component 330, and can be flexibly disassembled or replaced according to actual needs without changing the closing pressure structure and positioning of the main die.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the sorting component 320 includes two support plates 321 that are slidably mounted on the surface of the lower mold 200, two material frames 310 on both sides are respectively located on the surfaces of the two support plates 321, a receiving plate 322 is fixedly mounted on the bottom of the support plate 321, an induction pressure plate 323 is fixedly mounted inside the receiving plate 322, and an air pump 326 is fixedly mounted on the surface of the base 100.

[0031] In this embodiment of the invention, when the sheet metal is placed into the mold cavity area, the edge of the sheet metal contacts and presses down the sensing pressure plate 323 below the two support plates 321, triggering the start of the air pump 326 fixed on the base 100. The air pump 326 outputs airflow to drive the support plates 321 to perform a short-stroke left-right swaying motion. This swaying motion transmits power to the fixing frame 310 through the receiving plate 322, causing the fixing frame 310 to generate slight lateral vibration without leaving the initial installation position. This prompts the sheet metal to gradually move into position in the guide, quickly conforming to the positioning pin and the limiting edge, ensuring the accuracy of the sheet metal's positioning in the mold cavity.

[0032] It should be noted that the induction pressure plate 323 is used to detect the contact action during the feeding of the sheet metal. It is a trigger-type induction element, and its main function is to control the start and response of the lower-level actuator through mechanical pressing signal.

[0033] Piston plates 325 are fixedly installed on the bottom of both receiving plates 322. The piston plates 325 are slidably installed inside the lower mold 200. A regulating valve 327 is fixedly installed at the output end of the air pump 326. A first diverter pipe 328 and a second diverter pipe 329 are fixedly installed on both sides of the regulating valve 327, respectively. The two output ends of the first diverter pipe 328 are located on the adjacent side of the two piston plates 325, and the two output ends of the second diverter pipe 329 are located on the side of the two piston plates 325 that are far apart from each other.

[0034] In this embodiment of the utility model, when the sensing pressure plate 323 senses the signal of the plate being placed, it triggers the air pump 326 to start. The airflow is regulated by the regulating valve 327 and then enters the first diversion pipe 328 and the second diversion pipe 329 respectively, realizing the reciprocating drive of the two piston plates 325. By controlling the switching of the gas flow direction through the regulating valve 327, pressure can be applied alternately in two directions, driving the two piston plates 325 to achieve symmetrical sliding motion in the left and right directions, thereby causing the support plate 321 to shake slightly. The shaking action is synchronously transmitted to the fixed frame 310, which guides and fine-tunes the placed plate, allowing the plate to quickly slide into the target positioning area.

[0035] It should be noted that the regulating valve 327 is used to control the distribution and direction switching of the airflow output from the air pump 326, and is the core control element for realizing the reciprocating motion of the pneumatic drive structure in this utility model. The regulating valve 327 is located between the air pump 326 and the first diverter pipe 328 and the second diverter pipe 329. Its body can be a mechanical reversing valve, an electromagnetic reversing valve, or a pneumatic control valve structure, and has at least two output channels for guiding the airflow into the first diverter pipe 328 and the second diverter pipe 329 respectively. During operation, the regulating valve 327 can perform reversing operation according to control signals such as the trigger signal of the induction pressure plate 323 to realize the periodic switching of the airflow output direction.

[0036] The receiving plate 322 is slidably installed inside the lower mold 200, and the induction pressure plate 323 is embedded in the surface of the receiving plate 322.

[0037] In this embodiment of the utility model, the receiving plate 322 is configured as an elastic plate structure, which enables it to undergo controllable deformation when pressed by the plate or the support plate 321, thereby driving the sensing pressure plate 323 embedded on its surface to generate effective displacement, ensuring that the sensing pressure plate 323 can be successfully triggered even under low pressure.

[0038] Elastic sealing strips 324 are fixedly installed on both sides of the support plate 321, and the two elastic sealing strips 324 are fixedly connected to the lower mold 200 on the side that is far apart from each other.

[0039] In this embodiment of the utility model, the elastic sealing strip 324 is fitted into the gap between the support plate 321 and the lower mold 200 on both sides, which can effectively prevent dust, oil or debris from entering the slide rail area inside the lower mold 200 during the movement, and play a good sealing and protection role.

[0040] Multiple material-fixing frames 310 are located at the four corners of the sheet metal, and the top of each of the multiple material-fixing frames 310 is set as a sloping surface.

[0041] In this embodiment of the utility model, multiple positioning frames 310 form a four-point limiting and guiding structure, which can effectively limit the placement area of ​​the sheet material in the mold and prevent it from shifting in the horizontal or vertical direction. The top of each positioning frame 310 is designed as a sloping structure. During the placement of the sheet material, the sloping surface can provide a buffering and guiding function. When the edge of the sheet material contacts the sloping surface, it can slide smoothly into the positioning area below, reducing edge jamming or suspension.

[0042] like Figure 2 , Figure 3 and Figure 4 As shown, the replacement component 330 includes a mounting plate 331 fixedly installed on one side of the material frame 310, and the mounting plate 331 is fixedly connected to the surface of the support plate 321.

[0043] In this embodiment of the utility model, the fixed frame 310 can be quickly installed or removed from the support plate 321 via the mounting plate 331. When it is necessary to replace the door sill inner plate or connecting plate blank of different models or sizes, the fixed frame 310 of the corresponding specifications can be directly replaced.

[0044] A screw 332 is rotatably mounted on the surface of the mounting plate 331, and two screw holes 333 are opened on the surface of the support plate 321. The screw 332 is threadedly connected to the adjacent screw hole 333.

[0045] In this embodiment of the utility model, when replacing different models of the fixed frame 310, the installation or release operation can be completed simply by rotating the screw 332, eliminating the tedious disassembly steps and improving the replacement efficiency.

[0046] Working Principle: During use, the operator places the sheet metal for the connecting plate behind the inner sill plate into the feeding area above the lower mold 200. Multiple positioning frames 310 are distributed at the four corners of the sheet metal. The sloping structure at the top guides the edges of the sheet metal to slide naturally into the preset positioning area, achieving initial positioning. When the edge of the sheet metal contacts the support plate 321, the support plate 321 moves downward, causing the induction pressure plate 323 on the surface of the receiving plate 322 to move. After the induction pressure plate 323 is triggered, it outputs a control signal to start the air pump 326 on the base 100. The airflow generated by the air pump 326 is divided by the regulating valve 327 and enters the first diversion pipe 328 and the second diversion pipe 329 respectively, alternately supplying air to the adjacent and distant sides of the two piston plates 325, pushing the piston plates 325 below the two receiving plates 322 to perform reciprocating sliding motion. The reciprocating motion of the piston plate 325 causes the support plate 321 to sway slightly from side to side. This swaying motion is further transmitted to the fixed frame 310 above it, thereby performing micro-adjustment and automatic alignment of the plate, so that the plate can quickly slide into and fit into the positioning pin and limit block inside the mold, and complete the precise positioning.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
