Description

Technical Field

[0001] The invention relates to a tire mold and tooling for top cover hemming, belonging to the technical field of molds for automobile top cover processing. Background Art

[0002] The car sunroof is a popular configuration for cars nowadays. In order to meet the requirements of structure and functionality, the opening of the sunroof on the car roof needs to be hemmed, which is generally done by robot hemming. Because the sunroof needs to achieve a 180° hemming, there are very high requirements for the roller and the tire mold. The existing tire mold structure cannot meet the requirements. The sharp corner structure of the vertical edge leads to insufficient tire mold strength, making the tire mold easily damaged and unable to be repaired. Summary of the invention

[0003] Aiming at the problem that the existing tire mold for rolling hem of automobile roof is easy to be damaged, the invention provides a tire mold and tooling for rolling hem of roof.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a tire mold for top cover hemming, including a support body, characterized in that the support body includes an annular body in the shape of a skylight opening, the annular body is surrounded by a high side wall, a low side wall and two connecting side walls, grooves are arranged at the corners of the high side wall and the connecting side wall of the support body and at the corners of the low side wall and the connecting side wall, an arc-shaped suction cup mounting hole is arranged at the corner of the top surface of the annular body, and the arc-shaped suction cup mounting hole is connected with the groove; through holes are arranged on the high side wall and the low side wall, circular suction cup mounting holes are arranged on the top surfaces of the high side wall and the low side wall, and the circular suction cup mounting hole is connected with the through holes; an elliptical suction cup is installed in the arc-shaped suction cup mounting hole, and a circular suction cup is installed in the circular suction cup mounting hole.

[0005] The above-mentioned mold is a trapezoidal structure when viewed from the side. It can be used to position the outer panel of the top cover and match the shape of the outer panel of the top cover. It can also play a supporting role when the top cover is rolled. The positioning function of the mold can improve the accuracy of the rolling. The trapezoidal structure can disperse the force during the rolling, increase the strength of the mold, and avoid the mold from cracking and damage. At the same time, the trapezoidal structure is also convenient for cooperation with the roller.

[0006] The suction cups are distributed around the folded edge of the skylight, especially at the corners. It has been verified in practice that rolling defects are prone to occur at the corners and the workpiece is deformed. During processing, the skylight is prone to displacement at the corners of the tire mold. Two elliptical suction cups are arranged at the corners to strengthen the fixing effect on the top cover and reduce the possibility of displacement of the top cover at the corners of the tire mold.

[0007] On the basis of the above technical solution, in order to achieve the convenience of use and the stability of the equipment, the present invention can also make the following improvements to the above technical solution:

[0008] Furthermore, a reinforcing connecting plate is arranged between the high side wall and the low side wall, and the reinforcing connecting plate is located at the lower part of the high side wall and the low side wall. The reinforcing connecting plate is used to increase the stability between the high side wall and the low side wall, and plays the role of reinforcing ribs.

[0009] Furthermore, there are two through holes on the high side wall and the low side wall, and they are symmetrically arranged with the reinforcing connecting plate, and each through hole is equipped with a circular suction cup hole. Arranging two circular suction cup holes can place two circular suction cups, which can increase the adsorption effect on the top cover.

[0010] Furthermore, two elliptical suction cups are installed in the arc-shaped suction cup installation hole, and the two elliptical suction cups are arranged in a herringbone shape.

[0011] Furthermore, a fixing plate is arranged at the bottom of the inner corner of the annular body, and a bolt hole is arranged on the fixing plate. The fixing plate is used to fix the annular body on the tooling base.

[0012] At the same time, the present application also discloses a tooling using the above tire mold:

[0013] A tool for top cover hemming includes a base, characterized in that any one of the above-mentioned support bodies and four support columns are installed on the top surface of the base, and a plurality of clamps and fixtures are arranged around the support body and the four support columns.

[0014] Furthermore, the clamp is arranged on the high side wall and a base connected to the side of the side wall.

[0015] Furthermore, the four support columns include two high support columns and two low support columns, the two low support columns are located on the side of the support body, and a plurality of fixtures are installed on the side of the high support columns.

[0016] Furthermore, the clamp comprises a cylinder and a pressing arm mounted on the top of the cylinder, a pressing block is mounted on the end of the pressing arm, the pressing block is mounted on the pressing arm, the cylinder drives the pressing arm and the pressing block to achieve compression and opening, and the pressing block is located above the tire mold.

[0017] Furthermore, the fixture comprises a fixture column, and a hook-shaped fixture block is installed on the top of the fixture column.

[0018] The advantages of the present invention are: the top cover hemming mold designed by the present application has a simple structure, high strength, and relatively low requirements for the roller. By setting a reasonable mold structure, the force distribution on the mold during hemming is achieved, and an elliptical suction cup is set at the corner position to strengthen the adsorption of the top cover to avoid displacement of the top cover when it is stressed, improve the accuracy of hemming, and extend the service life of the mold.
