Description

Technical Field

[0001] The utility model belongs to the field of equipment for manufacturing oil tank shells, and in particular relates to a pulling and rolling mechanism of a pressing die. Background Art

[0002] For the production and manufacturing of fuel tank shells for automobiles, steel plates are usually bent and then welded to form. In addition to using traditional bending machines to bend steel plates, mold forming methods can also be used to make part of the shell, that is, the steel plate is placed on a lower pressing mold, and pressure is applied to it through a pressing block to make the steel plate fit the inner wall of the mold, thereby bending and shaping the steel plate. After a whole piece of steel plate is molded into a U-shaped steel plate part 1 at one time, the top plate 101, bottom plate 102 and side plates 103 of the fuel tank shell can be formed. Compared with using a bending machine for multiple bending, this molding method is obviously more efficient.

[0003] Our company's Chinese patent application number 2023235876152 discloses a down-pressing die for a fuel tank shell. Its structure is sophisticated. Through the design of movable over-correction parts and other structures, the steel plate can be formed after one molding. Figure 1 The U-shaped steel plate 1 is quick and efficient, and its top plate 101 and side plates 103 have good verticality, and there is no need to add subsequent shaping processes.

[0004] When pulling out the molded U-shaped steel sheet 1 from the above-mentioned mold, the operator will slightly fold the top plate 101 and the bottom plate 102 of the U-shaped steel sheet 1, and pull the top plate 101 and the bottom plate 102 on both sides. The top plates 101 and the bottom plates 102 on both sides are not prone to excessive friction with the inner surface of the mold, but the side plates 103 of the U-shaped steel sheet 1 will have severe friction with the inner bottom surface of the mold, making it difficult to pull out the U-shaped steel sheet 1 and also causing scratches on the surface of the workpiece.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] Based on the content in the background technology, the utility model discloses a pulling and rolling mechanism of a pressing mold, wherein an extension mounting plate is fixedly connected to one side of the opening of the base mold, two support plates arranged opposite to each other are fixed to the extension mounting plate, a screw rod is rotatably connected between the two support plates, that is, a rotating hole is opened on the support plate, the end of the screw rod is located in the rotating hole of the corresponding support plate, and a bearing is further arranged between the screw rod and the corresponding rotating hole, so that the screw rod can rotate along its own axis, at least one guide rod is fixedly connected between the two support plates, the guide rod and the screw rod are arranged in parallel, and there are two guide rods in the present application, which are arranged on both sides of the screw rod;

[0007] A slider is also provided between the two support plates, the slider is provided with a threaded hole and a through hole, the screw rod passes through the threaded hole of the slider and matches with the threaded hole of the slider in a threaded manner, the guide rod passes through the through hole of the slider, and a linear bearing is also provided between the guide rod and the through hole of the slider;

[0008] A universal ball is installed on the top of the slider, and the height of the universal ball is slightly higher than the height of the bottom surface of the base mold. The universal ball is a prior art, a light-load universal ball produced by Dongguan Shanglong Automation Technology Co., Ltd. The mounting plate at the bottom of the universal ball is fastened to the top of the slider by bolts.

[0009] The steel plate is molded into a U-shaped steel plate in the base mold, and the side plates of the U-shaped steel plate are in contact with the inner bottom surface of the base mold. When the U-shaped steel plate is pulled out from the base mold, the operator slightly folds the top plate and the bottom plate of the U-shaped steel plate, pulls the top plate and the bottom plate on both sides, and slightly lifts the U-shaped steel plate so that the surface of the side plate contacts the universal ball. Then, the U-shaped steel plate can be easily pulled out, and the surface of the U-shaped steel plate is not easily scratched. What is more important is that by turning the screw of the above-mentioned pulling and rolling mechanism, the slider can move along the direction of the screw, and the distance between the universal ball and the base mold can be adjusted to allow the universal ball to adapt to U-shaped steel plates of different widths.

[0010] Preferably, the ball body of the universal ball is also covered with a rubber sleeve, which can further prevent the surface of the U-shaped steel plate from being worn.

[0011] Furthermore, a crank is fixedly connected to the end of the screw rod, and the crank makes it easy for an operator to rotate the screw rod and adjust the position of the universal ball more conveniently.

[0012] Furthermore, a guide plate is arranged between the extension mounting plate and the support plate, the support plate is fixedly connected to the guide plate, and the guide plate is fixedly connected to the surface of the extension mounting plate by fasteners. The upper surface of the guide plate is smooth, and the bottom surface of the slider is smooth. The bottom surface of the slider is in sliding contact with the upper surface of the guide plate, so that the position adjustment of the slider is not affected after the slider contacts the guide plate. The setting of the guide plate can support the slider, avoiding that the pressure generated by the contact between the U-shaped steel plate and the universal ball falls entirely on the screw rod and the guide rod, causing the screw rod and the guide rod to deform due to heavy pressure, thereby extending the service life of the pulling and rolling mechanism.

[0013] Through the above technical solution, the utility model at least includes the following beneficial effects:

[0014] The pulling and rolling mechanism of the pressing mold described in the present application enables the operator to easily pull the U-shaped steel sheet out of the base mold, and the surface of the U-shaped steel sheet is not easily scratched; and more importantly, the pulling and rolling mechanism can conveniently adjust the distance between the universal ball and the base mold to allow the universal ball to adapt to U-shaped steel sheets of different widths.
