Description

Technical Field

[0001] This utility model relates to the field of automotive molds, and in particular to a drawing mold for the inner panel of the right side panel of a pickup truck. Background Technology

[0002] The inner right side panel of a pickup truck is a key component of the cargo box structure, typically made of thin stamped steel sheet. It works in conjunction with the outer right side panel to form the cargo box side panel. Through a specific flange design, such as a first connecting flange with its upper edge folded inwards, it is firmly connected to the outer right side panel, increasing the connection area and improving the rigidity and stability of the connection. A second connecting flange with its lower edge folded outwards vertically overlaps at least one of the inner and outer wheel arch panels. In some pickup truck cargo box structures, the inner right side panel is welded to the right end of the floor assembly, and together with the inner left side panel assembly and the floor assembly, forms a four-level sub-assembly of the cargo box, providing basic support for the cargo box's load-bearing capacity and effectively enhancing the overall structural strength and stability of the cargo box. See the standardized pickup truck cargo box assembly welding structure disclosed in utility model patent application number CN201621095997.4 for details. As a relatively large sheet material, the inner right panel experiences a significant increase in frictional resistance during the feeding process into the die core due to its larger overall contact area. This problem can easily cause local (end or side) positioning deviations in the sheet metal, which can lead to quality defects such as sheet metal tearing and cracking during the die-clamping process. The current material feeding and positioning scheme needs to be optimized and improved to enhance stability. Utility Model Content

[0015] Example 1, see appendix Figure 1-4 A drawing die for the inner right side panel of a pickup truck includes an upper base 1, a lower base 2, and a pressing frame 3. A support platform is provided in the middle of the lower base 2, and an inner panel punch 21 is provided on the support platform. The pressing frame 3 is fitted onto the support platform and the inner panel punch 21. An elastic support member 31, which is a gas spring, is provided between the pressing frame 3 and the lower base 2 to provide elastic support for the pressing frame 3. After the pressing frame 3 slides downward and is drawn, it can automatically spring back to its original position. A lower extension stage 32 is provided at the inner end of the pressing frame 3. Several positioning heads 33 are evenly arranged between the main body of the upper base 1 and the pressing frame 3. The positioning heads 33 accurately restrict the plate material on the lower extension table 32 and the inner plate punch 21. The inner plate die 11 is provided in the middle cavity of the upper base 1. The inner plate die 11 can be matched and fitted onto the inner plate punch 21. The outer edge of the inner plate die is provided with an upper extension table. A blind hole 13 corresponding to the position of the positioning head 33 is provided between the upper extension table 12 and the main body of the upper base 1. During the die closing and stamping process, the positioning head can be matched and extended into the blind hole to avoid conflict.

[0016] The surface of the pressure frame 3 is evenly provided with several round pads 34, and the corresponding position of the surface of the upper base 1 is provided with a round boss 14. The round pads and round bosses provide support for the upper base and the pressure frame, reducing the impact force of mold closing.

[0017] Both ends of the inner plate punch 21 are provided with telescopic holes. The push rod 22 provided in the cavity of the lower base 2 extends into the telescopic holes. The overall area of ​​the right plate is relatively large. After the inner plate punch 21 is closed and drawn, it will be adsorbed on the surface of the punch, and there is a phenomenon that the material cannot be removed. At this time, the push rod 22 extends out through the telescopic hole to push the plate, so that the drawn product can be separated from the punch.

[0018] When using this drawing die, the sheet metal is placed between the positioning heads 33 of the pressure frame 3, and the sheet metal is accurately fitted onto the inner plate punch 21. Then, the upper base 1 is driven to move downward to close the die. After the die is closed, the inner plate die 11 and the inner plate punch 21 contact and press to fix the sheet metal. The upper extension pull table 12 on the pressure frame 3 and the upper extension pull table 12 on the upper base 1 contact and clamp the edge of the sheet metal. The pressure frame 3 is compressed by the air spring and moves downward. The upper and lower drawing tables clamp and fix the edge of the sheet metal and stretch it downward outside the inner plate punch 21 to achieve drawing.

[0019] Example 2, see appendix Figure 3 , 5 -6. This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: two feeding detection devices 4 are diagonally arranged between the positioning heads 33, including a T-shaped seat, a photoelectric sensor 41, an active plate 42, and a linkage plate 43. The photoelectric sensor 41 is horizontally fixed to the lower part of the vertical plate 44 of the T-shaped seat. The bottom plate of the T-shaped seat has an elongated hole 431 with a positioning screw inside, which facilitates fine adjustment of the position of the detection device. The active plate 42 is connected to the slide groove 46 in the middle of the vertical plate 44 through a slider 45. The active plate 42 and the slider 45 are rotatably connected, so that the active plate can rotate relative to the slider and slide along the slide groove 46 through the slider 45. The upper inner side of the active plate 42 has a guide slope 421. The linkage plate 43 is rotatably connected to the upper end of the vertical plate 44 through a rotating shaft 47. The upper side of the active plate 42 has a short shaft 422, which is fitted into the elongated hole 431 in the upper part of the linkage plate 43. The short shaft and the elongated hole are slidably connected.

[0020] One side of the active plate 42 is provided with a guide guard plate 48 that is fixedly connected to the vertical plate 44. The guide guard plate 48 provides protection for the active plate 42, avoiding the weight of the plate material from generating a large impact force on the active plate 42, and ensuring the service life and detection accuracy of the detection device.

[0021] The principle of the feeding detection device 4 is as follows: During the process of placing the sheet metal into the punch, the edge of the sheet metal will contact the guide inclined surface 421 of the active plate 42, causing the active plate 42 to slide and flip. The active plate 42 drives the linkage plate 43 to rotate through the short shaft 422. When the linkage plate 43 blocks the photoelectric sensor 41, it triggers the signal that the sheet metal is placed in place, which accurately identifies whether the sheet metal is placed in place, avoiding quality defects such as sheet metal tearing and cracking during the die-closing stamping process, and improving the drawing forming quality of the product.

[0022] Example 3, see appendix Figure 1-3 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that a guide rod 51 is vertically fixed to the surface of the edge of the lower base 2, and the guide rod 51 is slidably fitted into the sliding hole on the side of the pressure frame 3. During the process of the upper base 1 moving downward and contacting the pressure frame 3 to close the mold, the pressure frame 3 slides downward along the inner plate punch 21. At this time, the sliding hole on the pressure frame 3 slides along the guide rod 51, and the guide rod 51 provides guidance for the movement of the pressure frame 3, thereby improving the stability of the drawing and improving the drawing accuracy.

[0023] The upper part of the sliding hole has a relief hole 52 on the pressure frame 3. The upper end of the guide rod 51 extends out of the relief hole 52, and a shim 53 is provided at the upper end of the guide rod 51. The relief hole is provided to increase the guide stroke of the guide rod, and the shim 53 is used to increase the contact area between the guide rod 51 and the upper base 1, thereby reducing the reverse downward pressure impact force on the upper base 1.
