Abstract
A kind of method of utilizing low carbon steel, Cuprum alloy, aluminum alloy web to make bearing support cover belongs to the production technology of bearing support cover, and the present invention divides blanking, several procedures such as welding, moulding, punching and surface treatment.For eliminating welding stress and cold work hardening.Can after welding, carry out material heat treatment.The present invention can improve stock utilization significantly, reduce production costs.
Description
The invention belongs to the production technology of bearing support cover
Existing bearing retainer lid all is to adopt the metal material stamping forming, adopt this method to produce bearing support cover, stock utilization is low, the cost height, with external diameter φ 242, internal diameter φ 218 type bearing support covers is example, stock utilization only 14～16%, if adopt big or small supporting punching press, can improve stock utilization to a certain extent, yet in actual production, impossible suitable, the particularly more single Production of bearing producer of various bearing ratios for product type, adopt metallic plate punching manufactured bearing support cover, the extremely difficult stock utilization that improves.
The object of the present invention is to provide a kind of technology simply to utilize low carbon steel, Cuprum alloy, aluminum alloy web to make the method for bearing support cover, so that improve stock utilization significantly, reduce cost.
Main points of the present invention are the annulus outer radius D according to required bearing support cover
2, annulus inside radius D
1, annulus thickness H calculates the cross-section area S and the length L of desired low carbon steel, Cuprum alloy, aluminum alloy web, to draw good web guaranteeing that length is coiled circle and blanking on the cylinder of L, with mold pressing or roll forming again after the circle jointing firm welding.
Description of drawings:
Fig. 1 is the bearing support cover schematic representation
Fig. 2 is the web schematic representation
Technological process of the present invention is as follows:
Blanking → welding → moulding → punching → surface treatment.
Below in conjunction with accompanying drawing and technological process the present invention is done detailed description:
Eliminate rust and the pickling two procedures for thicker before blanking, should the peeling off of scale with the more serious low carbon steel web of corrosion.The rust cleaning of peeling off can add 0.5% urea carrying out immersing pickling in sulfuric acid or the hydrochloric acid solution after the low carbon steel strip material eliminates rust through peeling off on the derusting machine of peeling off in acid solution, to prevent pickle brittleness, will neutralize in the low carbon steel web immersion lime water after the pickling.
1, blanking: earlier low carbon steel, Cuprum alloy or aluminum alloy web are pulled on stretcher that cross-section area S=(π (D22-D21) H)/(the rectangular material of π (D2+D1)+l) guarantees that at cross section girth is L=π (D with the rectangular material after stretching
2+ D
1On the cylinder of)+1 the coiled circle and by length L to rectangular material blanking (D wherein
2Be bearing support cover annulus outer radius, D
1Be bearing support cover annulus inside radius, H is a bearing support cover annulus thickness, and l is the welding procedure allowance, and when adopting butt welding, l is 2～3 millimeters, and when adopting gas welding or arc welding, l is 1～2 millimeter).
2, welding: for the low carbon steel web, adopt butt welding, gas welding or arc welding with circle jointing firm welding, butt welding is adopted in suggestion, to improve welding quality and work efficiency, for Cuprum alloy or aluminum alloy web, adopt gas welding with circle jointing firm welding, before welding, should clear up weld port for improving welding quality, when using butt welding, should make welding end surface smooth, and remove deburring, during with gas welding or arc welding, the groove that then should keep weld port should not make end face smooth.
3, moulding: the circle after the firm welding is placed on mold pressing or roll forming in the mould, can compression molding on friction screw press or oil hydraulic press, or on rolling mill, roll the rail moulding.
For eliminating welding stress and cold work hardening, improve the quality of products, can after firm welding, heat-treat circle, for the low carbon steel web, if cold-drawing deformation is 30% when above, the employing normalized treatment, normalizing temperature is 820～840 ℃, grain growth tendency when being out of shape to eliminate, if amount of deformation less than // 30%, adopts recrystallization annealing to handle, annealing temperature is 500～700 ℃, when heat treatment, should prevent oxidation and decarbonization, adopt recrystallization annealing to handle for Cuprum alloy or aluminum alloy web, Cuprum alloy circle annealing temperature is 300～500 ℃, and aluminum alloy circle annealing temperature is 200～400 ℃, after circle is heat-treated, carry out mold pressing or roll forming again.
4, punching, according to the bearing support cover designing mould, on punch press, carry out punching.
5, surface treatment: after the punching,, can carry out copper facing, zinc-plated or surface blackening processing to product according to the requirement of user to product.
The present invention is owing to adopt mild steel, copper alloy, aluminium alloy web to make bearing support cover, thereby utilization rate of raw materials is increased substantially, stock utilization is general all more than 95%, the restriction that is not formed a complete production network simultaneously, decrease production cost, simultaneously the product mechanical performance can all reach the specification requirement of plate stamping moulding.
