The workshop is equipped with imported welding equipment such as various shearing machines and resistance welding machines, with an annual output of 4,000 sets of bus parts, which can undertake the production, assembly and welding of various sheet metal parts.
The parts painting workshop under the Division has two production lines: frame line and comprehensive line, which can complete the pretreatment processes such as degreasing, pickling, phosphating and priming of large-area structural parts such as chassis frame and floor frame by assembly line. The workpiece can continuously complete a series of processing procedures such as primer baking, topcoat spraying and topcoat baking on the conveyor chain. The baked workpiece can be used directly, and the annual design production capacity of the whole production line is 3000 pieces (single shift system).
The comprehensive line has a closed spraying processing line integrating degreasing, pickling and phosphating, and two suspended conveyor chains. Workpieces enter 10 relatively independent spraying rooms of the whole spraying processing line in turn on the conveyor chain, and a large number of nozzles realize omni-directional multi-angle spraying, achieving good processing effect. The comprehensive line also includes a steam drying room, a spray painting room with water rotating bottom and top, and a spray booth with bottom and top. A series of process steps, such as pretreatment, primer spraying and topcoat spraying, can be realized at one time on the conveyor chain. The product can be used online immediately after it goes offline, and the production efficiency is extremely high. The annual designed production capacity of this production line is 6.5438+340 thousand pieces (single shift system). Its products range from various connectors, sealing plates, panels, flat plates, box assemblies, steel beam assemblies and various skeleton assemblies to iron front and rear panels of passenger cars.
The company is also equipped with special physical and chemical laboratories, most of which are imported testing equipment, which can track and test the raw materials for painting and the bath liquid of degreasing tank, pickling tank and phosphating tank at any time in the production site to ensure that the key parameters meet the process requirements and ensure the painting quality. The main large-scale equipment in the sheet metal stamping line of the stamping parts division are: German imported coil straightener, 800t, 630t and 400t closed double-point single-action press, 1030 /450t double-action sheet metal stretching hydraulic press, etc. TC500R punching machine imported from Germany with international advanced level can process various high-precision plates with two-dimensional shapes, which is the same as V- 150t imported from Germany.
The sheet metal stamping line equipped with the above key equipment covers an area of 3,700 square meters and can undertake large-scale and multi-variety processing of various large-scale sheet metal stamping parts. The production capacity of this production line supporting bus body stamping parts is 7000 sets/year. On the basis of meeting the production requirements of bus panels of Yaxing Bus Co., Ltd., we have produced panels for Changfeng Cheetah and other products.
