Abstract
The heat treatment process of cylinder of internal combustion engine is characterized by using the principle of electric resistance can produce heat to utilize the contact of electrode contactor with cylinder to produce contact resistance to implement the surface quenching of internal wall of the cylinder. The special equipment used by said invented method-electric hydraulic transmission system is used to drive electrode shaft to make it up and down reciprocably move, and a motor drive system is used to drive the electrode shaft to make it implement roatary movement so as to make the electrode contactor do curvilinear motion on the wall of the cylinder to attain the goal of implementing heat treatment on the surface of the cylinder.
Description
The present invention relates to a kind of heat treatment technics, a kind of specifically for heat treatment method of international combustion engine cylinder and device.
At present, the oil engine repairing trades when cylinder is heat-treated, employing be laser heat treatment method.The cylinder quenching effect that this method is handled is better.But, this LASER HEAT TREATMENT equipment price costliness, up to hundreds of thousands of unit, and with the cylinder of this device processes, repair expense is also higher.
The objective of the invention is to want to provide a kind of and both can reach the Laser Heat Treating in China effect same.But equipment manufacturing cost is lower, the method and apparatus that repair expense is also lower.
Technical scheme of the present invention is as follows:
Produce the principle of heat according to resistance, processed cylinder and planar slide electrode are connected in the two ends of transformer respectively, control voltage is at 2-6V, electric current is at 350-800A (alternating-current), and electrode axis drives through motor transmission system and rotates, and motor shaft is under the drive of hydraulic power actuating system, also pump simultaneously, electrode contact contacts with cylinder inner wall, carries out curve and moves, and the linear velocity that moves is in 8-25 rice/minute scope.The local temperature of electrode contact contact cylinder reaches quenching temperature rapidly.After electrode contact moved away, this local temperature spread to cylinder body rapidly; Reach cooling, promptly finish quenching process.Hardened face can form grid-shaped, and water is corrugated, or sinusoidal waveform etc.
For the equipment of realizing aforesaid method mainly is by transmission gear for electric motor.Vulcan gear and power supply transformation, e Foerderanlage are formed.Motor transmission system is made up of the gear in electrodeless variable-speed motor, the slide teeth roller box.Hydraulic power actuating system is made up of hydraulic ram, piston rod, tail rod.Power supply transformation, delivery system are made up of transformer, lead, terminal stud, planar slide electrode, electrode axis, electrode contact and one group of electrode stage clip.
Advantage of the present invention is that this method is simple to operate, and expense is low, and equipment manufacturing cost only is about 1/tens of a LASER HEAT TREATMENT equipment, and treatment effect is identical with the LASER HEAT TREATMENT effect, and the hardened face degree of depth reaches 0.1-0.25mm, and hardness reaches HRC59-61.
Below in conjunction with accompanying drawing method and apparatus of the present invention is further described:
Fig. 1 is the front view of present device
Fig. 2 is the side-view of present device
Embodiment:
Processed cylinder body is placed on the insulcrete of present device platform, electrode axis and cylinder are adjusted into concentric, adjust electrode contact, make it to be fit to cylinder radius, be fixed on the electrode axis.The transformer output terminal is connected with the slide teeth roller box with cylinder body respectively, there is flexible lead to connect between the slide teeth roller box peace face sliding electrode, the transformer output voltage is adjusted at 2V, adjust the reciprocating speed of motor speed and piston, the linear velocity that makes electrode contact move on cylinder inner wall is 15 meters/minute.
From Fig. 1 and Fig. 2 as can be known, an insulcrete 14 is arranged below processed cylinder body 8, the terminal studs 7 above the cylinder body 8 connect transformers, and transformer also links to each other with terminal stud 15 on the planar slide electrode 2 by the terminal stud 6 on the slide teeth roller box 10.Electrode axis 1 upper end links to each other with planar slide electrode 2, lower end connection electrode contact 13, electrode contact 13 can be changed or adjust according to the size of cylinder bore, one group of electrode stage clip 11 is arranged between planar slide electrode 2 and the slide teeth roller box 10, the effect of electrode stage clip 11 is to allow planar slide electrode 2 contact with electrode axis 1 closely, and present embodiment has adopted 4 springs.Gear 4, the gear 3 connection electrode axles 1 of motor 5 in slide teeth roller box 10, hydraulic ram 9 is equipped with at tail rod 12 tops, and slide teeth roller box 10 is contained on the tail rod 12, and top is connected with piston rod, and is pumped along tail rod 12 by the piston rod drive.
