S bend forming mechanism used for skylight guide rail

Abstract

The invention belongs to the technical field of automobile parts and provides an S bend forming mechanism used for a skylight guide rail. The S bend forming mechanism comprises a lower die seat, a material pressing plate, a beating block and a forming assembly. A carrying seat is arranged on the lower die seat. The skylight guide rail is divided into a body part and a forming part. The material pressing plate is arranged at the upper end of the lower die seat and is opposite to the body part to be used for firmly pressing the skylight guide rail. A hinge assembly used for driving the forming assembly to move is arranged in the lower die seat. The forming part is arranged on the forming assembly in a sleeving manner. The beating block and the forming assembly are vertically opposite to eachother. The beating block moves downwards to act on the forming assembly, and the forming assembly swings along the hinge assembly to bend the forming part to be in the S-shaped direction from the straight direction. The S bend forming mechanism has the beneficial effects that the hinge assembly and the forming assembly are used for swinging, the forming assembly serves as an inner core of the skylight guide rail so that it can be ensured that the forming face of the skylight guide rail is smooth and does not contract, circular beads are smooth, the rebounding is small, precision is high, andpart taking and placing are convenient.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to an S-bending forming mechanism for sunroof guide rails. Background technique [0002] Such as figure 1 Shown is a car sunroof, where the right end of the sunroof guide rail needs to be bent into an S shape during the production of the car sunroof, as shown figure 2 As shown, here it is required that the deformation range of the inner surface of the inner rail after the S-bend of the sunroof guide rail is within 0.2mm, and the smooth transition of the rounded corners and the flat bottom surface must be maintained. There is no equipment in the prior art that can perform S-bend forming at one time. Multiple processes are required for the S-bend forming process, the forming steps are complex, and the deformation range of the inner surface is relatively large during forming, the rounded corners cannot be smoothly transitioned, and it is troublesome to take and place parts, and the ...

[0002] like figure 1 Shown is a car sunroof, where the right end of the sunroof guide rail needs to be bent into an S shape during the production of the car sunroof, as shown figure 2 As shown, here it is required that the deformation range of the inner surface of the inner rail after the S-bend of the sunroof guide rail is within 0.2mm, and the smooth transition of the rounded corners and the flat bottom surface must be maintained. There is no equipment in the prior art that can perform S-bend forming at one time. Multiple processes are required for the S-bend forming process, the forming steps are complex, and the deformation range of the inner surface is relatively large during forming, the rounded corners cannot be smoothly transitioned, and it is troublesome to take and place parts, and the forming efficiency is low, so it is necessary to design a A mechanism that can perform S-bend forming at one time
