a complete sense of the steel office furniture production process from raw materials preparation, through the production of woodworking, paint coating composition to final product packaging warehousing and other steps. Mention of production process of steel office furniture in many people seem very simple, three step one cutting, edge, drilling, the device also is not had outside saw, edge machine, drill. Essential structure is nothing more than 32 series dismounting connectors, is actually steel office furniture production process than the much more complex, also is a piece of plate, some as long as one or two processes can be completed, and some ten or even dozens of procedures to complete the. If the drawer bottom, as long as the feed can, such as the structure of a more complex ground cabinet panel is honeycomb hollow, surface veneer, solid wood edge and side edge type, but also above the glass mosaic. Processing of single panel to 20 procedure to complete, so that the design complexity, is closely related to plate technology and product structure, materials and production line product varieties of species number and other factors, the more the elements involved in more complex. Plate the main elements of the production process: raw materials, process documents, machinery and equipment, operators and the corresponding quality and manufacturing management system. Time and place where raw materials is the prerequisite and basis for the entire process, while the process files is a whole process flow and management actions according to a comprehensive and detailed, process documents. steel office furniture process documents about: effect chart, three view, components decomposition diagram, parts processing diagram, hardware accessories inventory, packaging solutions, installation diagram, raw material list (BOM), parts processing flow sheet, product use. The parts diagram and parts processing flow sheet used in combination and parts production line synchronous optimal running effect. The main contents of parts machining process inside the table to cover the name, specification, number, material, batch processing, the basic content of note, special maintenance scale, working hours, working procedure and sequence number. Machinery and equipment and operating workers are processing security.

1. steel office furniture main production process:
   steel office furniture because of its surface material and the surface decorative effect is not the same process, yyli090708 mainly represent categories: steel office furniture, veneer stickers steel office furniture, solid color steel office furniture, melamine steel office furniture and composed of over for another two or more hybrid don't steel office furniture.
   don't steel office furniture process based process, there are some special, such as bending plate with thickness. The actual operating process, due to the influence of factors such as cost, usually you have me, I have you, it is worth mentioning is widely used with honeycomb core, machining steel office furniture will be more complex.
   
   assembly combined structure of
   file cabinet is equipped with a manual operation structure of
2. structure, which comprises a column, shelves, hanging plate, side panel, chassis parts assembly.
   in accordance with the provisions of track laying, installation of transmission mechanism, anti fall device;
   track with expansion bolts or nail installation.
   provided with dust, rat proof, moisture-proof and sealing device.
3. maker
   each scale day after assembly, overall dimensions (length, width, height) of the limit deviation 1mm;
   per scale day after assembly, clearance at the side panel and on the back of which is less than 1mm;
   rail mounting, the parallelism error of not more than 1mm/m, is not more than 1mm; uniform cross section of the parallelism error is less than 1mm/m, length of not more than 1mm; the parallel deviation
   per two tracks of less than 1mm; rail joint height difference is not greater than 0.3mm.
   consisting of segments of low beam assembly after the linearity is not more than 0.5mm/m, length of not more than 1mm.
   parts of the unmarked tolerance limit deviation in GB1804 IT13-14.
4. 
   all sheet metal parts manufacturing and processing, machine processing after grinding burr, no crack, no scar. All of the
   welding, welding firm, smooth, pass.
   in a combination between product components can maintain interchangeability.
5. five, driving device of
   transmission mechanism: a mechanical type automatic lifting driving device. Keep the parts, assembly parts interchangeability.
   transmission components:
   wave: wave plate type by hand rocking handle type, installation of brake control, smooth operation. The
   axis: made of 45# steel, the processing precision of 3.2, after quenching and tempering heat treatment HB220~290.
   sprocket: made of 45# steel, reference GB1244-84 (3R profiles) scale, the forging molding, tempering to stress, processing machine, hobbing, keyseat, to the hair teeth, tooth by frequency quenching of HRC60-62.
   bearings: adopting 204 bearing.
   chain: the 12.7 pitch ball chain (the chain Co., Ltd.). According to GB1135-89 thickness according to chain 1/2 "international made.
   roller: using ZG35, cast steel, the processing molding.
   Rail: using 45# steel, cold rolled steel.
   pipe: seamless tube.
6. load function requirements of
   single shelf with an average load of 40kg, double the average distributed load 80kg, the maximum deflection is less than 4mm, 24h after unloading shelf, no cracks, residual deformation is not more than 0.3mm.
   scale section (six layerdouble shelf) at full load (each single shelf uniformly distributed load 40kg) case, column frame, without significant deformation of the frame body, not dumping phenomenon.
   full load conditions, the cabinet in practical operation run freely, no blocking phenomenon. Each scale Festival manual shaking force shall not be less than 12N.
   under all load 1/20 force (horizontal force along X, Y axis two direction) the role of repeated 100 times, lifting force, frame generated by the inclination of not greater than the total height 1%, bracket, without significant deformation of column.
7. surface coating material requirements: in accordance with GB-1720, 1732, 1734 scale
   1, degreasing, rust treatment: oil,
   workpiece surface rust and oxidation layer, the degreasing cleaning chemical method, no oil, emulsion and other dirt, the surface is completely soaked with water. The
   after pickling, no visible oxide, rust and other phenomena of erosion, the surface luster basic average.
   phosphating process: phosphating treatment mainly by impregnation method.
   phosphating treatment with zinc and calcium dihydrogen phosphate as the main composition of solution, the preparation, regulate phosphating bath, according to process requirements. The
