Description
Technical field
The present invention relates to die wear technical fields, specifically, more particularly to a kind of for the abrasion examination of pin disk-type friction
The temperature control cooling pin fixture for testing machine is mainly used in detection body of a motor car plate stamping process to punching press upper die and lower die
Material loss caused by abrasion between plate and the variation of the wearing depth of plate and mold.
Background technique
Currently, high-strength steel is used it extensively, although plate in punching press production in the superperformance in workpiece production
Expect the stamping metal forming technology important as one kind, it is mature to be applied in modern industry manufacture, but vehicle
Wagon sheet needs to stamp forming, especially hot press-formed, can be related to the fretting wear of plate mold, these molds are in punching press
It will receive the abrasion repeatedly of plate in the process, its boss height, depth of groove can be gradually reduced over time, meeting after degree is deepened
The correct forming for seriously affecting plate, influences body quality.
Chinese utility model patent (application No. is 201620157805.1) " the pin disk-type friction abrasion with cooling device
Testing machine ", which disclose a kind of friction wear testing machines, wherein being provided with cooling device on lower main shaft, are mainly used for
The problems such as structure is complicated in the prior art, and noise is big, and heat dissipation effect is poor is solved, the temperature control aspect of test pin is not mentioned
And.
For friction wear testing machine (such as HT-1000), in simulation drop stamping friction process, in-furnace temperature is relatively easy to
Control, but the working face temperature sold can change with friction, most important to the control of the temperature of pin.In different temperature
Setting lower drawing abrasion will also be different, then it is determined that a necessary temperature setting is essential test
, temperature control processing just solves this series of problems.
Summary of the invention
Temperature adjusting can not be carried out according to the cooling pin set forth above because of existing friction wear testing machine, thus cannot
The technical issues of fretting wear is affected by precise control of temperature, and provide a kind of for pin disk-type friction wear test
The temperature control cooling pin fixture of machine.The present invention is mainly fixed on pin mandril using the coolant jacket with tube wall inside and outside bilayer, and
It monitors the temperature of pin end in real time by temperature sensor, and then passes through coolant liquid in temperature controller feedback control coolant jacket
Flow velocity, to realize the control of adjustable temperature, emulator is largely increased.
The technological means that the present invention uses is as follows:
A kind of temperature control cooling pin fixture for pin disk-type friction abrasion tester characterized by comprising
Temperature controller is fixed on the upper end of pin mandril and is located at the lower section of counterweight, and the top of the pin mandril passes through spiral shell
Line is connected on the cover of testing machine, and the pin mandril has double hierarchic structures；
Coolant jacket has the U-shaped structure of tube wall inside and outside bilayer, is nested with and is fixed on the pin mandril and is fixed with the one of pin
End, the coolant jacket accommodate the first stepped part and second step ladder of the pin mandril, and the pin is fixed on described first
The end of stepped part, the coolant jacket are fixedly connected on the inner sidewall of the testing machine by coolant jacket outer tube wall；
Be equipped between the inside and outside tube wall of the coolant jacket by U-shaped space be longitudinally separated into liquid zone and liquid zone out every
Plate, it is described enter bottom position of the liquid zone with liquid zone out in the pin be connected to, wherein it is described enter liquid zone and liquid zone out respectively with it is described
Coolant inlet above coolant jacket is connected with cooling liquid outlet；
The temperature controller passes through conducting wire in the pin mandril and the temperature sensor phase that is arranged in above the pin
Even, when work, the temperature of the pin end is monitored in real time by the temperature sensor, and then anti-by the temperature controller
Feedback controls the flow velocity of coolant liquid in the coolant jacket.Due to controlling flow rate of water flow by temperature controller, to control pin
Temperature, pin disk frictional wear experiment is carried out using the pin under different temperatures environment.
Further, the inner tube of the coolant jacket has and first stepped part of pin mandril, second step ladder phase
The hierarchic structure matched, including the second receiving portion for accommodating the pin mandril second step ladder and for accommodating the pin mandril
First receiving portion of the first stepped part, the sky between the second inner tubal wall of second receiving portion and the coolant jacket outer tube wall
Gap width is L1, the gap width between the first inner tubal wall of first receiving portion and the coolant jacket outer tube wall is L2, meet L1
< L2。
Further, the lower end of the coolant jacket is with hemispheric end face, and hemispheric end face avoids sharply
The vortex that coolant liquid caused by part generates, there are also the heat concentration phenomenons that sharp area easily causes, and mitigate furnace high-temperature and press from both sides to pin
The ablation of tool extends the service life of fixture.The end face of the lower end of the coolant jacket is equipped with the hole passed through for the pin end, institute
The bottom edge for stating the first receiving portion is fixedly connected to form sealing by the outer in interconnecting piece and the hole.Sealing primarily to
It prevents coolant liquid from leaking, flows coolant liquid only in the double-layer structure of coolant jacket.
Further, the interconnecting piece has the conical structure to match with the pin, and the cone angle of the interconnecting piece is big
In the cone angle of the pin.
Further, the coolant jacket is nested with fix after, end face and the pin mandril second step ladder upper end thereon
