Embodiment Construction

[0019] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0020] See Figures 1 through 7.

[0021] The present invention includes a welding process and a machining process, the welding process is to weld parts according to the structure, adjust the shape individually after welding, and then assemble and weld to form; the machining process is segmental processing before welding of the track plate, leaving Expansion joints, alignment, and grinding; After the track beams are welded and formed, the shape is adjusted and corrected, and after aging treatment, the bottom surface and key grooves are processed as a whole.

[0022] Please refer to Figure 4 to Figure 6. Track plate 009 is cut into 6 sections, 1 piece in the first section, 4 pieces in the middle section, and 1 piece in the tail section, about 2...

Abstract

The invention relates to a manufacturing process of a track beam of a cooling bed dolly in a hot rolled plate line, which is characterized in that the invention comprises a welding process and a machining process; the welding process is that the welding is achieved according to the structures of parts; separate shaping and correcting are carried out after the welding is achieved, and the assembly welding and forming are carried out; the machining process is the processing of the track plate by sections before the welding; an expansion seam is preserved at butted position and is aligned and levelled by grinding; after the assembly welding and forming of the track beam, the shaping and correcting are carried out, and a bottom surface and a keyway, etc. are integrally processed through an aging disposal. The invention ensures the qualified rate of the products, saves the occupied time of the large machine tool equipment, reduces the manufacturing cost, and shortens the manufacturing period.

Description

technical field [0001] The invention relates to a manufacturing process of a track beam, in particular to a manufacturing process of a hot-rolled plate line cooling bed trolley track beam. Background technique [0002] At present, the track beam of the cooling bed trolley of the hot-rolled plate line (hereinafter referred to as the rail beam) is the walking track of the pallet trolley in the cooling bed, and the steel plate to be cooled is carried on the trolley. The length of the piece is more than 12000mm, and the thinnest part of the wall thickness is only about 10mm, and the piece is mass-produced. According to the traditional process, after the overall welding is completed, the overall processing is performed with a large machine tool. Due to the thin structure, the overall deformation after welding is serious, and some even cannot be corrected; due to the high cost of large-scale machine tools, the manufacturing cost of the part is too high, and the manufacturing cycl...
