Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the utility model fluid temperature control cupping testing machine is divided into upper and lower two parts:Upper part is by upper
Mould 4, switch knob 5, cover plate 10 are constituted;Lower part is by workbench 1, hydraulic system, oil groove 2, high temperature resistant fluid 3, holding pad
6th, heating tube 7, thermocouple 8, lower mould 9, coaming plate 12 are constituted.Lower mould 9 is punch-pin in embodiment, and upper mould 4 is cavity plate.Wherein binder
By column level on workbench 1, holding pad center is provided with binder hole to plate 6;Lower mould 9 is arranged on workbench 1, lower mould 9
Positioned at the lower section of holding pad 6 and just to binder hole.Hydraulic system is provided with below workbench, hydraulic system is connected to drive with lower mould
Lower mould lifting.Oil groove 2 is provided with high temperature resistant fluid 3 on workbench 1 in oil groove 2;Adding for heating fluid is provided with oil groove 2
The thermocouple 8 of heat pipe 7 and detection oil liquid temperature, heating tube 7 and thermocouple 8 are connected with control system, and control system is according to thermoelectricity
The oil liquid temperature of even collection controls the start and stop of heating tube.The lower mould 9 and holding pad 6 are respectively positioned in oil groove 2 and are submerged in resistance to height
In warm fluid 3;Coaming plate 12 is arranged on outside oil groove 2 and is surrounded with by oil groove 2, is provided with rotatable by shipping and reselling on another market in the upper surface of coaming plate 12
Cover plate 10, cover plate 10 is used for the open capping in the upper end of coaming plate 12, and the upper mould 4 is arranged on cover plate 10 by coaming plate opening capped configuration
Lower surface on.If oil groove is circle, usual coaming plate and cover plate are also circle.If oil groove is rectangle, usual coaming plate
Also it is rectangle with cover plate.
In order to realize the reliable locking of cover plate and coaming plate, the upper mould 4 is installed in rotation on cover plate 10, on upper mould 4
The lock projection 13 for crossing out laterally is provided with, the upper end of coaming plate 12 crosses out to form lock nosing 14 to inner side;In upper mould 4
The switch knob 5 for driving upper mould to rotate is provided with, after cover plate 10 is by the open capping of coaming plate 12, rotating switch handle 5 can make locking
Raised 13 are located under lock nosing 14.During unblock, 90 ° of rotating switch handle makes lock projection disengage lock nosing, now
Rotating plate.
In order to ensure that upper mould can also be heated by fluid, make blank forming temperature more accurate, the utility model requirement cover plate
10 by under the open capped configuration of coaming plate 12, and the lower end of upper mould 4 is also submerged in fluid 3.
The control of this testing machine temperature is that the heating tube for leaning on control system is heated to the fluid in oil groove, and by temperature
Degree inductor(Thermocouple)Detected in real time, heating is stopped after reaching design temperature, heated automatically if temperature drop.Work
When making, the fluid 3 in oil groove is heated by heating tube 7 first;After reaching design temperature, rotating plate 10 closes upper mould 4, and
90 ° of rotary switch handle locks cover plate and coaming plate, sees Fig. 1.After upper mould 4 enters fluid 3, the upper mould 4 of fluid 3 pairs is heated.When
Lower mould 9 is up under hydraulic system effect after reaching predetermined temperature;Upper mould 4 coordinates the Plastic Forming for completing plate 11 with lower mould 9,
Computer system automatic data collection related data in forming process;Part of the upper die is finally opened, plate 11 is taken out with manipulator, see Fig. 2.
Some explanation:1st, oil groove inner fluid height is not spill over fluid into lower contour forming completion position by upper mould to be defined;
2nd, in the first task, mould is slightly long into the fluid heating-up time at present, and under continuous duty, the lower mould heating-up time is shorter(Because
There is certain temperature), have substantially no effect on operating efficiency;3rd, because whole process is to carry out in a certain temperature conditions,
So should not manually operate, can be worked with automatic mechanical hand, so also improve operating efficiency and product percent of pass.
Example:The temperature control AEG-process of aluminium alloy plate:The fluid in workbench finishing bathtray is first warming up to 300 DEG C, by machine
Be placed on aluminium alloy plate to be measured on holding pad by tool hand, then closes and part of the upper die and locks, and hydraulic clamping cylinder starts, and makes to wait to measure and monitor the growth of standing timber
Material is between holding pad and upper mould and clamps, and after reaching predetermined clamping force, main hydraulic cylinder starts to start, and makes lower mould by material pressure
Enter and carry out Plastic Forming in upper mould.After the completion of shaping, lower mould backhaul playback, workpiece is stayed in mould, and computer system is recorded automatically
The testing data of lower material.Upper mould is finally opened, workpiece is taken out, a workflow is so far completed, next circulation industrial is waited
Make.
The utility model fluid temperature control cupping testing machine, is controlled in cupping testing machine by the high-temperature oil liquid in oil groove
The temperature of detected materials, and entirely descend mould core(Lower mould, holding pad etc.)All it is to be submerged in fluid, so can guarantee that
Temperature constant state, when upper mould(Cavity plate)When going downwards in fluid, can also conduct heat rapidly.Further make by when cavity plate reaches oil temperature
Material is plastically deformed in the case of constant temperature, and the material data for so measuring is carried out under temperature constant state, therefore result
It is more accurate, and temperature-controllable.
Finally it should be noted that examples detailed above of the present utility model is only to illustrate the act that the utility model is made
Example, and it is not the restriction to implementation method of the present utility model.Although applicant is with reference to preferred embodiment to the utility model
It has been be described in detail that, for those of ordinary skill in the field, it can also have been made on the basis of the above description
The change and variation of his multi-form.Here all of implementation method cannot be exhaustive.It is every to belong to of the present utility model
Obvious change that technical scheme is amplified out changes row still in protection domain of the present utility model.
