Abstract
The invention discloses a reinforcement technology of a tool withdrawal groove of a cylinder liner, which has the implementing method that a rolling tool is installed on a lathe, and has the rolling implementing method that the rolling tool is installed on the lathe, wherein an elastic device is added at the handle structure of the rolling tool, the diameter of the rolling tool is 1/3-1/2 of that of the tool withdrawal groove of the cylinder liner, 24 circumferential grooves are uniformly distributed along the circumferential direction of the rolling tool, when normal rolling is carried out, the rolling force is 1000N, the rolling velocity is 50r/min, the rolling number is 24, when the rolling tool carries out rolling operation on the tool withdrawal groove of the cylinder liner roll, the rolling tool also generates the stable impact except normally exerting the rolling force at each rotation, as a result, the invention has the effects that: the rolling force is small, the rolling surface quality is improved, the wear-resistant property is good, and the fatigue resistance and the conquassation-resistant capability are increased.
Description
Affiliated technical field
The present invention relates to a kind of new rolling technology that cylinder sleeve supporting shoulder escape carries out intensive treatment.
Background technology
Cylinder jacket is the core part of engine, also is consumable accessory, but the disconnected platform incident of cylinder jacket often takes place; Along with the power of engine require increasingly high; Though can improve the escape intensity of the supporting shoulder of cylinder jacket through traditional rolling technology, in order to reach certain roll extrusion effect, the roll extrusion power that needs are bigger; Technology also is difficult to guarantee to reach the requirement of reinforcement in concrete production process, also can cause the fracture failure of cylinder sleeve platform simultaneously because of roll extrusion power greatly.
Summary of the invention
In order to improve the mechanical performance of cylinder sleeve, reduce the inefficacy fracture that traditional rolling technology possibly bring, the present invention provides a kind of impact type rolling technology, through this technology, can increase the fatigue resistance of cylinder jacket, the place's surface peening of cylinder jacket grinding undercut,
The technical solution adopted for the present invention to solve the technical problems is, after the mach cylindrical fine finishining its supporting shoulder carried out a kind of specific roll extrusion and handles in the grinding undercut position down, and then carrying out inner bore honing and process.
The invention has the beneficial effects as follows that carry out impact type roll extrusion processing in the escape position down through the supporting shoulder to cylinder jacket, the anti-fatigue performance of cylinder jacket improves, cylinder sleeve fracture failure probability lowers, and improves the service life of product.
Description of drawings
This specification does not have accompanying drawing.
The practical implementation method
The technical solution adopted for the present invention to solve the technical problems is: traditional cylinder sleeve escape reinforcement process is to adopt the roll extrusion mode; But need bigger roll extrusion power; Just can reach strengthening effect; Less roll extrusion power will reach the effect that the escape resistance to compression is burst, and needs the roll extrusion of long period, and strengthening effect is lower simultaneously.Because the structural stress that escape exists is concentrated, bigger roll extrusion power causes the roll extrusion fracture easily.This technology is after fine finishining finishes at cylinder jacket part cylindrical position its supporting shoulder escape to be carried out a kind of special roll extrusion to handle, and then the honing endoporus.The implementation method that its roll extrusion is handled is that a hobboing cutter is installed on lathe, increases by an elastic device on this roll extrusion cutter Knife handle structure, between the 1/3-1/2 of cutter diameter and cylinder sleeve escape diameter; Circumferentially be uniformly distributed with 24 road circumferential slots, when normal roll extrusion, roll extrusion power is 1000 Ns; Rolling speed is 50r/min, and the roll extrusion number of times is 24 times, when hobboing cutter and the roll extrusion of cylinder sleeve escape; Hobboing cutter whenever rotates a circle; Hobboing cutter has also produced stable impact except normally having applied roll extrusion power, such effect is that roll extrusion power is little, the surface quality of rolling surface improves, anti-wear performance is good, strengthens antifatigue and the routed ability of resistance to compression.
Claims (1)
1. cylinder sleeve escape reinforcement process, it is characterized in that: through diameter is the 1/3-1/2 hobboing cutter of cylinder sleeve diameter, and the hobboing cutter of 24 road grooves is circumferentially arranged, and adopts 1000 Ns of impact type roll extrusion of roll extrusion power to handle.
