Abstract
The invention relates to an impact rolling technology. In the implementation method for rolling, a hob is installed on a lathe; an elastic device is added on the hob handle of the hob; six circumferential grooves are evenly distributed at the periphery of the hob; and under the condition of normal rolling, when the hob and a cylinder jacket grinding undercut are contacted and rolled, a spring can generate impact vibration while the hob and the cylinder jacket grinding undercut contact with the circumferential grooves each time, the evenly distributed grooves can generate a fixed vibration frequency, and the hob can generate a shot blasting-like effect due to the vibration effect. Thus, the impact rolling technology has the double characteristics of shot blasting and rolling, the pressure of the rolling is small, the roughness of the surface is improved, the wear-resistance is good, and antifatigue and anti-bruising capabilities are obvious.
Description
Affiliated technical field
The present invention relates to a kind of technology that grinding undercut carries out roll extrusion under the cylinder jacket supporting shoulder.
Background technology
Cylinder jacket is the core part of engine, it also is consumable accessory, but the disconnected platform incident of cylinder jacket often takes place, along with the requirement of the power of engine is more and more higher, though can improve the grinding undercut intensity of the supporting shoulder of cylinder jacket by traditional rolling technology, in order to reach certain roll extrusion effect, the roll extrusion power that needs are bigger, wayward in concrete production process, also can be because of the excessive fracture failure that causes cylinder jacket of roll extrusion power.
Summary of the invention
In order to improve the mechanical performance of cylinder jacket, reduce the inefficacy fracture that traditional rolling technology may bring, the invention provides a kind of impact type rolling technology, by 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 to its supporting shoulder under the grinding undercut position carry out the impact type roll extrusion and handle, and then carry out inner bore honing processing.
The invention has the beneficial effects as follows that carry out impact type roll extrusion processing in the grinding undercut position down by the supporting shoulder to cylinder jacket, the anti-fatigue performance of cylinder jacket improves, disconnected platform probability lowers, and improves the service life of product.
Description of drawings
This specification does not have accompanying drawing.
Specific implementation method
The technical solution adopted for the present invention to solve the technical problems is: traditional roll extrusion power is bigger, and less roll extrusion power can not play the surface peening effect, but bigger roll extrusion power causes the roll extrusion fracture easily.This technology is after the fine finishining of cylinder jacket part cylindrical position finishes grinding undercut under its supporting shoulder to be carried out the impact type 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, increase by an elastic device on this roll extrusion cutter Knife handle structure, the uniform 6 road circumferential slots of hobboing cutter periphery, when normal roll extrusion, when hobboing cutter contacts roll extrusion with the cylinder jacket grinding undercut, when touching circumferential slot at every turn, spring can produce one and impact concussion, uniform like this groove can produce fixing concussion frequency, the effect of such concussion just makes the effect of hobboing cutter generation shot-peening the same, so have the dual characteristics impact type rolling technology that is equipped with shot-peening and roll extrusion concurrently, roll extrusion power is little, the roughness on surface improves, anti-wear performance is good, strengthen the routed ability of antifatigue and resistance to compression.
Claims (1)
1. the impact type rolling technology is characterized in that: produce fixing concussion frequency by hobboing cutter and form the impact type roll extrusion processing that has roll extrusion and bead characteristics concurrently.
