Description

Technical Field

[0001] The utility model relates to the technical field of automobile door inner panel drawing dies, in particular to an automobile door inner panel drawing die. Background Art

[0002] Drawing dies, also known as deep drawing dies, are dies used to draw metal sheets into cup-shaped or arc-shaped parts, such as small metal cups or large car body molding. In a car, the parts that make up the car body are roughly divided into panel parts, structural parts, running parts and reinforcement parts. These parts have different performances corresponding to different use requirements. The drawing performance has an important influence on the forming process of the car's panel parts. In the process of deep drawing of the inner panel of a car door, a drawing die is required. The upper and lower die seats on the drawing die are used to limit the periphery of the plate. The sliding of the blank holder and the hydraulic press top rod can achieve the drawing of the periphery of the inner panel of the car door.

[0003] The existing Chinese patent with announcement number CN217617129U proposes a drawing die for an automobile door inner panel, which can solve the problem that the width of the sheet material will gradually decrease compared with the original sheet material during the drawing and forming process of the automobile door inner panel in the existing drawing die for automobile door inner panel, and the sheet material is easily offset, so as to avoid the sheet material moving too fast when the width of the sheet material is gradually reduced, thereby causing the clamping plate to not position it in time, so that the sheet material is offset;

[0004] However, although the above-mentioned automobile door inner panel drawing die can position the sheet material through the electric telescopic rod, connecting plate, spring, connecting rod and clamp, in cooperation with the first threaded rod and the movable plate, the device can be moved more conveniently through the support rod and the universal wheel, in cooperation with the bottom plate, and the movable plate can be limited during the movement through the limit groove, in cooperation with the movable plate, to avoid the phenomenon of the movable plate being offset during the movement; but the simple clamping and limiting using the threaded rod and the small-range movable plate will inevitably lead to clamping offset during the drawing process due to the small clamping force and friction force, resulting in the production of defective products. At the same time, it lacks the side blocking effect, making it difficult to save it even if it is offset during the drawing process, thereby easily increasing the probability of defective products.

[0042] like Figure 1-4 As shown, the embodiment of the utility model provides a drawing die for the inner panel of an automobile door, characterized in that it comprises: a working frame 1, a clamping plate 4 and a lateral limiting plate 10; a plurality of auxiliary rods 6 are uniformly penetrated on the clamping plate 4; a push rod 8 is arranged between the auxiliary rod 6 and the clamping plate 4; a suction cup 12 is fixedly installed at the bottom of the push rod 8; a fixed paddle 7 is arranged on the outer surface of the auxiliary rod 6; the lateral limiting plates 10 are respectively arranged on both sides above the working frame 1;

[0043] Specifically, by providing a plate fixer consisting of an auxiliary rod 6, a fixed paddle 7, a push rod 8 and a suction cup 12, the suction cup 12 can be adsorbed and released through the fixed paddle 7, so that when the inner door panel is clamped and fixed, if improper clamping or clamping offset occurs, compared with fixing methods such as bolt locking and spring tightening, the paddle can be quickly adjusted to quickly move the improperly clamped or offset inner door panel, thereby accelerating production efficiency.

[0044] like Figure 1 and Figure 3As shown, the drawing auxiliary plate 3 includes: a moving rod 5, which is respectively installed in the grooves opened at the inner side ends of the drawing auxiliary plate 3; a clamping plate 4, which is connected to the outer surface of the moving rod 5 and embedded in the grooves opened in the drawing auxiliary plate 3; a connecting plate 15, which is respectively installed at the two ends of the bottom of the drawing auxiliary plate 3 and embedded in the grooves opened at the top of the working frame 1; a threaded sleeve 16, which is installed through the inside of the connecting plate 15 and is threadedly connected to the transmission shaft 14 in the groove opened at the top of the working frame 1. Two clamping plates 4 are arranged in front of the drawing auxiliary plate 3, and they are both connected to the moving rod 5, can be freely moved up and down, and are all provided with auxiliary rods 6, fixed paddles 7, push rods 8 and suction cups 12, and they can form a plate fixer and are arranged oppositely;

[0045] Specifically, since a movable rod 5 is provided in the groove of the drawing auxiliary plate 3, and the clamping plate 4 is connected to the movable rod 5, and two upper and lower opposite clamping plates 4 and plate fixers thereon are provided, the present invention can be used for automobile door inner panels of various thicknesses, and can clamp, fix and draw the automobile door inner panels placed inside the two clamping plates 4. At the same time, since the clamping plates 4 and the movable rod 5 are in a non-fixed connection relationship, the automobile door inner panels that become thinner after drawing can also be effectively and quickly clamped and fixed during the drawing process.

[0046] like Figure 1-4 As shown, the work frame 1 includes: a drawing auxiliary plate 3, which is respectively located at the front and rear ends of the top of the work frame 1; a lateral auxiliary plate 9, which is respectively located at the left and right sides of the work frame 1; a controller 2, which is installed at the bottom of the work frame 1; a double-axis motor 13, which is installed inside the work frame 1, and the double-axis motor 13 includes: a transmission shaft 14, which is respectively connected to the front and rear output ends of the double-axis motor 13 and is threadedly connected to the threaded sleeve 16; and the double-axis motor 13 is installed on both sides of the inside of the work frame 1;

[0047] Specifically, since the dual-axis motor 13 is installed inside the work frame 1, the dual-axis motor 13 can be protected by the work frame 1, so that its service life can be extended. At the same time, the transmission shaft 14 connected to it is hidden, which can reduce the problem of damage to the transmission shaft 14 that makes the new model unusable to a certain extent, and improve the aesthetics to a certain extent. By setting an external controller 2, it is convenient for workers to stand on the side to check the drawing condition of the drawn automobile door inner panel, and the driving speed of the dual-axis motor 13 can be quickly and efficiently controlled through the controller 2, reducing the probability of producing defective products.

[0048] like Figure 2As shown, the lateral auxiliary plate 9 includes: a lateral limiting plate 10, which is located at the inner end of the lateral auxiliary plate 9 and is connected to the lateral auxiliary plate 9 through a damping spring rod 11; a damping spring rod 11, which is respectively arranged between the lateral auxiliary plate 9 and the lateral limiting plate 10, and both extend out of the grooves opened at the inner end of the lateral auxiliary plate 9; the lateral limiting plate 10 can be closely embedded in the grooves opened at the inner end of the lateral auxiliary plate 9, the lateral auxiliary plate 9 is arranged to be movable up and down, and the lateral auxiliary plate 9 including the lateral limiting plate 10 does not collide with the drawing auxiliary plate 3 that can move forward and backward,

[0049] Specifically, by providing a lateral limit plate 10 connected by a damping spring rod 11, the lateral limit assembly of the present invention can be flexibly adjusted, and a variety of automobile door inner panels of different widths can be used, thereby enhancing the practical use effect of the present invention. At the same time, since the lateral auxiliary plate 9 can be moved up and down, effective lateral blocking adjustment can be performed for automobile door inner panels of different thicknesses. Since the lateral limit plate 10 can be tightly embedded in the groove provided in the lateral auxiliary plate 9, when the maximum lateral blocking of the present invention is reached, the lateral blocking length will not be affected.

[0050] Working principle: Before use, the long ends of the inner panel of the car door that needs to be drawn are respectively extended into the two clamping plates 4 at the front and rear ends. After the inner panel is fixed and clamped by the plate fixer, the worker can start the dual-axis motor 13 through the controller 2, so that the dual-axis motor 13 drives the drawing auxiliary plate 3 to move forward and backward respectively to draw the inner panel. At this time, the worker can stand on the side to observe the inner panel being drawn, and use the lateral limit plate 10 to limit the side of the inner panel being drawn. Through continuous observation, when it is found that the drawn inner panel may be offset, it can be quickly loosened through the fixed paddle 7 for rapid adjustment, thereby enhancing work efficiency. At the same time, the friction clamping of the suction cup 12 of the plate fixer, the locking clamping effect of the clamping plate 4 and the lateral limit plate 10 can reduce the possible offset of the inner panel during drawing, so as to reduce the probability of defective products in the production process.
