Abstract
The invention relates to the processing of the inner walls of cylinders of hydraulic bracket jacks and upright columns, in particular to a processing method for cladding inner walls of cylindrical workpieces by using a stainless steel material. The processing method replaces the conventional copper tin alloy-plated cylinder inner wall processing method, and the deformed inner holes of the cylinders can be repaired by the processing method. The method comprises the following steps of: 1) selecting a stainless steel cylinder; 2) roughly processing the inner wall of the cylindrical workpiece; 3) loading the stainless steel cylinder into the cylindrical workpiece, fixing one end of the stainless steel cylinder with the corresponding end of the cylindrical workpiece by spot welding, and fixing the cylindrical workpiece to a machine tool; 4) placing a rolling extrusion device which is driven by the machine tool into the stainless steel cylinder, and driving the rolling extrusion device to work so as to radially extrude the stainless steel cylinder until the stainless steel cylinder is closely combined together with the cylindrical workpiece; and 5) machining the two ends of the cylindrical workpiece. The inner hole of a scrapped cylinder can be repaired by the processing method, and the effects of preventing corrosion, sealing and resisting wear can be achieved by the stainless steel material instead of the copper tin alloy which is plated to the inner hole of the cylinder or other anticorrosive wearable materials.
Description
Technical field
The inner wall of cylinder that the present invention relates to hydraulic support jack, column is handled, and specifically is a kind of processing method that stainless steel material coats the cylindrical workpiece inwall of using.
Background technology
Cylinder barrel is the vital part of hydraulic support jack, column and other hydraulic transmission part, and the crudy of its endoporus directly affects the serviceability and the reliability of whole hydraulic part, and the cylinder barrel endoporus requires high wearability and corrosion resistance simultaneously.In order to improve wearability and corrosion resistance, and adapt to abominable condition of work, mainly adopt stainless steel tube directly to process, or carry out inner wall copper plating ashbury metal (thickness of coating 0.03～0.04mm) after turning, roll extrusion, the cleaning with the common material steel pipe; Adopt stainless steel tube directly to process, because raw materials consumption is big, cost is very high.And carry out inner wall copper plating ashbury metal after the machining and the cylinder barrel that forms with the common material steel pipe; Decay resistance is low under adverse circumstances; And the bronze (copper-tin alloy) electroplating environmental pollution is very serious, and the expense of the waste liquor contamination that produces in the inwall bronze (copper-tin alloy) electroplating process being implemented harmless treatment is high.Pollute in order to protect environment to reduce, many producers all cancel bronze (copper-tin alloy) electroplating equipment, and adopt stainless steel tube directly to process.
In addition; The cylinder barrel endoporus very easily is out of shape under abominable condition of work; And by prior art, also be difficult to repair, as the jack of stacking in a large number on the production scene, reprocessing from the ore deposit, steel parts such as the fairlead of inner dress and piston can utilize through repairing a little again; But critical component cylinder barrel Internal Hole Deformation surpasses product drawing 0.40～0.50mm and is scrapped, and real feel unfortunately.
Summary of the invention
The present invention implements to repair in order to be out of shape endoporus to cylinder barrel in order to substitute the inner wall of cylinder processing method of existing bronze (copper-tin alloy) electroplating simultaneously, and a kind of processing method that stainless steel material coats the cylindrical workpiece inwall of using is provided.
The present invention adopts following technical scheme to realize: use the processing method that stainless steel material coats the cylindrical workpiece inwall, step is following:
1), according to the internal diameter of pending cylindrical workpiece, select the stainless steel cylinder of corresponding specification;
2), treat the inwall of handling cylindrical workpiece and carry out roughing;
3), the stainless steel cylinder that step 1) is selected is encased in through step 2) in the cylindrical workpiece of roughing, and to the corresponding endpoint solid welding of stainless steel cylinder one end and cylindrical workpiece calmly, at last cylindrical workpiece is fixed on the lathe;
4), will place in the stainless steel cylinder by the rolling pressurizing unit that lathe drives; Drive the work of rolling pressurizing unit; Stainless steel cylinder is implemented radial compression, and combining closely until stainless steel cylinder and cylindrical workpiece becomes one, and the completion stainless steel material is in the coating of cylindrical workpiece inwall; The rolling pressurizing unit of said realization above-mentioned functions is easy to realize for a person skilled in the art.
5), press the code requirement of cylindrical workpiece, machining is carried out at the two ends of the cylindrical workpiece after handling through step 4) gets final product.
Compared with prior art, the present invention is coated on the cylindrical workpiece inwall with reasonable, simple method with stainless steel material, and through roll extrusion, stainless steel material and cylindrical workpiece is combined into one, and improves the surface quality of cylindrical workpiece endoporus.
In addition, the distortion that causes because of environmental changes such as temperature for the cylinder barrel of hydraulic support jack or use and cause distortion can be carried out the coating of stainless steel material to cylinder barrel according to the method for the invention fully, accomplishes and repairs, and still can continue to use.If the cylinder barrel after repairing is in long-time use, the stainless steel material clad of endoporus wearing and tearing occur or damages, can machining place to go clad, and the coating of again inner wall of cylinder being carried out stainless steel material can also be repaired use.Promptly adopt the method for the invention reparation to scrap the cylinder barrel endoporus; Cylinder barrel can be utilized again; So just avoid the processing that feeds intake again, the cylinder barrel endoporus working surface inwall after the reparation does not need bronze (copper-tin alloy) electroplating, but economical with materials expense, workman's processing charges and bronze (copper-tin alloy) electroplating expense.
The method of the invention is simple, reasonable; Not only can repair the cylinder barrel endoporus of scrapping; Cylinder barrel endoporus bronze (copper-tin alloy) electroplating or other corrosion-proof wear-resistant material be can also replace, anticorrosion, sealing and wear-resisting effect reached, the environmental pollution of avoiding bronze (copper-tin alloy) electroplating to cause simultaneously.
