Description

Technical Field

[0001] This application belongs to the technical field of waste bin transition hangers, and in particular relates to a waste bin transition hanger and a waste bin transition hanger processing device. Background Technology

[0002] Waste bins are typically connected to the rail transit vehicle frame using transition hangers. Generally, the transition hanger body thickness is required to be above 8mm, and the thick product must achieve a flatness tolerance of 0.5mm. Since the flatness tolerance requirement is relatively high compared to welded products, most existing similar products use 10mm material, which is bent and welded, and then the surface is milled using a CNC lathe to achieve the aforementioned flatness tolerance requirement. The existing process (material blanking - bending - welding - milling - hole enlargement - pickling and passivation - surface treatment) is prone to material waste. At the same time, the use of CNC lathes in the process increases the number of steps, resulting in higher processing costs. Utility Model Content

[0038] As another aspect of this application, a waste bin transition support processing device is provided for processing the aforementioned waste bin transition support. This device is used to bend the main body plate, a crucial component of the support, referring to… Figure 1 , Figure 5 , Figure 6 As shown, the system includes a drive end, an upper cover plate 20, and a lower base plate 21. The drive end is connected to the upper cover plate 20 to drive the upper cover plate 20 to move downward. Multiple guide posts are provided between the upper cover plate 20 and the lower base plate 21. One end of each guide post is fixedly connected to the upper cover plate 20, and the other end of each guide post passes through the lower base plate 21 and is movably connected to the lower base plate 21. Each guide post has a guide sleeve 22 fitted at both ends, and the two guide sleeves 22 are fixedly connected to the upper cover plate 20 and the lower base plate 21, respectively.

[0040] The processing steps for the body plate described above are as follows:

[0041] Step 1: Select a body plate of the required length and thickness of 8.2mm;

[0042] Step 2: Place the above-mentioned body plate at the first concave mold, and drive the fixed plate to press down the first convex mold through the drive end. The cooperation of the concave and convex molds causes the body plate to form the first 90° bend.

[0043] Step 3: Place the bent body plate at the second die, and drive the fixed plate to press down the second punch through the drive end. The cooperation of the die and the body plate forms a second 90° bend. When the second bend is performed, the first 90° bend will rotate towards the through groove of the waist of the second punch. When the end of the first 90° bend contacts the inner end face of the through groove, the second 90° bend is completed and a U-shaped body is formed.

[0044] Step four: Place the U-shaped body at the correction module, and drive the fixed plate through the drive end to press the correction punch down on the inside of the U-shaped body. The correction module corrects the two bending angles of the U-shaped body.

[0045] In the above process, the reinforcing ribs of the suspension seat are welded to the center line of the U-shaped body after correction, i.e., the inner wall of the U-shaped body, to provide support and tensile strength for the entire suspension seat. After welding, the first and second reinforcing plates are welded to their corresponding positions to strengthen the connection between the suspension seat and the vehicle frame and the waste bin. After the first and second reinforcing plates are welded, holes are drilled simultaneously on the first and second reinforcing plates, as well as the first and second horizontal parts. This completes the processing of the entire suspension seat.
