Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to a guide rail bracket and a stamping method thereof. Background Art

[0002] In elevator shaft construction, guide rail brackets are key components for supporting and fixing equipment. However, traditional brackets usually adopt a simple bent sheet structure, and the overall frame strength mainly depends on the thickness of the material. This design is difficult to significantly improve the structural strength without increasing the thickness of the material, resulting in easy deformation when subjected to large loads or external impacts, thus affecting the stability of the entire system. In addition, the design of traditional brackets is also insufficient in terms of material utilization. The materials in many areas are not effectively utilized, which not only does not play a significant role in the strength of the overall bracket, but also causes a waste of stamping sheets. In particular, when processing pressure guides or other additional parts, additional materials and processing steps are often required, increasing manufacturing costs and complexity. Summary of the invention

[0003] The object of the present invention is to provide a guide rail bracket and a stamping method thereof. The bent edge formed by the integrated stamping process significantly enhances the overall stiffness and bending resistance of the first bracket. The first area and the second area are three-dimensionally bent downward to form reinforcing ribs, thereby further improving the structural strength of the second bracket. The material of the third area is formed into a pressure guide plate for fixing the guide rail through integrated stamping, so that the excess material contained in the original bracket is reused, thereby solving the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

The provision of the bent edge 13 significantly improves the overall strength of the first bracket 1 , and can significantly increase the overall frame strength of the structural parts without increasing the thickness of the stamping plate material.

[0028] The first connecting plate 11 is connected with the pressing guide plate 3 by bolts. The size is adjusted according to the distance of the guide rails. The second connecting plate 12 and the third connecting plate 21 are connected by bolts, and then the pressing guide plate 3 is clamped to the main guide rail.

[0029] The second bracket 2 includes a third connecting plate 21 and reinforcing ribs 22. The reinforcing ribs 22 are symmetrically provided at the upper and lower ends of the third connecting plate 21, so that the frame strength of the second bracket 2 can be greatly improved without increasing the material thickness; the plane where the third connecting plate 21 is located is parallel to the plane where the second connecting plate 12 is located, and the third connecting plate 21 and the second connecting plate 12 are connected by bolts; the reinforcing ribs 22 include a first reinforcing panel 221 and a second reinforcing panel 222.
