Abstract
The invention discloses a lining machine method, which comprises the following copper-based double-metal steel strip processing steps: 1) feeding; 2) punching to form hasps; 3) punching to form a U shape; 4) rounding; 5) finely rounding; 6) milling excircle; and 7) boring inner circle. The method is characterized in that the step 5 of finely rounding, the step 6 of milling excircle and the step 7 of boring inner circle are accomplished by one extrusion process for forming the required surface roughness and wall thickness of the lining. The method has high economy and high processing property and can improve an on-site working environment greatly.
Description
Technical field
The present invention relates to a kind of sliding bearing processing technique field, is the processing method of lining specifically.
Background technique
Sliding bearing of the internal-combustion engine mainly comprises bearing shell, lining, flange watt and thrust plate.Lining is very extensive in the use of internal combustion engines, comprises connecting rod, cam shaft bush, rocker arm bush etc.We can say that lining is the strength member in the internal-combustion engine as important sliding bearing part, the quality of lining performance directly affects the performance of motor.Along with the fast development in Chinese internal-combustion engine market, the demand of lining is constantly increased.
The processing method of conventional bushings is 1) blanking, because the Cuprum alloy steel band is an entire plate, according to the concrete size of lining, need at first carry out blanking, as Fig. 1; 2) towards hasp, the finished product of lining be one cylindric, guarantee the reasonable fastening of lining, need to carry out fastening, as Fig. 2 with hasp; 3) towards U-shaped, before being full circle, U-shaped compares crucial operation, and be that material is carried out pre-bending, so that carry out full circle, as Fig. 3; 4) full circle becomes cylindrical with materials processing, as Fig. 4; 5) finishing circle, the wall thickness and the surface roughness of assurance lining are to guarantee the reasonable assembling of lining, as Fig. 5; 6) cylindrical grinding, the wall thickness and the surface roughness of assurance lining are to guarantee the reasonable assembling of lining, as Fig. 6; 7) circle in the boring is as Fig. 7.Because the defective that this conventional machining process exists, cause lining in use, often take place to damage in advance, influence the machine life of internal-combustion engine, there is defective in particularly this conventional machining process always when controlling the circularity of lining, circularity by the traditional diamond-making technique lining can only guarantee more than the 0.015mm always, concerning high strength lining especially connecting rob bushing, because the load that connecting rod bears is big, the circularity of lining itself influences its stressed distribution, is subjected to very big influence the working life of lining.In addition, the method for this tradition processing lining produces metal fillings in the working procedure, and promptly grinding machine produces metal fillings, and needs vacuum cleaner to handle, so environmental-protecting performance is poor.
Summary of the invention
The processing method that the purpose of this invention is to provide a kind of lining, the surface roughness of reduction lining, the circularity of raising lining makes lining have long service life, good environmental protection, has favorable manufacturability and Economy.
Purpose of the present invention is achieved through the following technical solutions.
A kind of processing method of lining is by implementing the following step to copper bimetallic steel band: 1) blanking; 2) towards hasp; 3) towards U-shaped; 4) full circle; 5) finishing circle; 6) cylindrical grinding; 7) circle in the boring is characterized in that: flexiblely in described step 5) finishing circle, step 6) cylindrical grinding, the step 7) boring cross the one procedure extruding and finish, with formation needed surface roughness of lining and wall thickness.
Wherein pushing required power is air pressure or hydraulic pressure.
Pressure that described extruding is required and rate travel can be regulated continuously.
The fixed mould of described extruding is a punch structure, or the die structure.
Institute's copper bimetallic steel band is a copper lead alloy, or lead-free copper-based alloy.
Described extrusion process uses on traditional manual processing line, or uses on semi-automatic and the automatic line.
The present invention also has following advantage:
1) the present invention makes full portion in traditional topmost operation finishing circle, cylindrical grinding, the boring into the one procedure extruding and finishes promptly crowded circle.
2) the present invention's copper-based alloy material of processing lining can use traditional copper-lead bimetal steel band and lead-free, does not influence the technology capability of processing.
3) by check, the lining of the present invention's processing, its surface roughness can reach below the 0.6 μ m, is better than 0.8 μ m of traditional diamond-making technique; The circularity of lining can be reduced to 0.005mm from 0.015mm.
4) owing to make full portion in finishing circle, cylindrical grinding, the boring into one procedure and push to finish and promptly reduced multiple working procedure, reduced the use of material, cost per unit can descend 20%.
5) the present invention in use, air pressure adopts pressurized air, does not produce metal fillings in the working procedure, and the metal fillings that grinding machine produces in traditional processing method needs vacuum cleaner to handle, so the present invention is greatly improved the work on the spot environment, has the favorable environment protection energy
6) processing method of lining of the present invention can be widely used in the production and the application of internal-combustion engine lining.
The performance of the present invention and comparative example relatively sees the following form:

Fig. 1-the 7th, the processing method 1 of corresponding conventional bushings respectively) blanking, 2) towards hasp, 3) towards U-shaped, 4) full circle, 5) the finishing circle, 6) cylindrical grinding, 7) the interior circle of boring, the structure principle chart of 7 steps;
Fig. 8 is the structure principle chart of extrusion process of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
The processing method of a kind of lining of the present invention is by implementing the following step to copper bimetallic steel band: 1) blanking; 2) towards hasp; 3) towards U-shaped; 4) full circle; Finish lining 1 needed surface roughness and wall thickness by extruding then, promptly by squeezing circle, the mode by extruding realizes that round three process in finishing circle, cylindrical grinding, the boring finishes the processing of lining 1 exactly.Wherein pushing required power is air pressure or hydraulic pressure, and pushes required pressure and rate travel can be regulated continuously.Fixed mould during extruding is a die structure 3, and the extruding flexible mould of another correspondence is a punch structure 2, and fixed mould also can be a punch structure certainly.Extrusion process of the present invention uses on traditional manual processing line, or uses on semi-automatic and the automatic line.Copper bimetallic steel band of the present invention is a copper lead alloy, or lead-free copper-based alloy.
Fig. 1-4 wherein also is in the processing method of the present invention must promptly be the first step through step, and as Fig. 1, blanking because the Cuprum alloy steel band is an entire plate, according to the concrete size of lining, need at first carry out blanking; Second the step as Fig. 2, towards hasp, the finished product of lining be one cylindric, guarantee the reasonable fastening of lining, need carry out fastening with hasp; The 3rd step, as Fig. 3,, before being full circle, U-shaped compares crucial operation towards U-shaped, and be that material is carried out pre-bending, so that carry out full circle; In the 4th step, as Fig. 4, full circle becomes cylindrical with materials processing.
