Description

Technical Field

[0001] The utility model relates to the technical field of material plastic forming, and particularly relates to a high-temperature and high-pressure torsion device. Background Art

[0002] The high-pressure torsion technology is the best solution for refining grains in plastic deformation. The high-pressure torsion device mainly consists of a pressure head and a die. The material is placed in the die, and a large pressure is applied to it through the pressure head. At the same time, the pressure head is rotated to make the material undergo special plastic deformation of axial compression and tangential shear. The magnitude of the deformation is determined by the number of rotation turns. During the deformation process, the forces in all directions are uniform, and the obtained grain size is small and uniform. At present, the high-pressure rotation technology has been studied on aluminum alloys, copper alloys, titanium alloys, composite materials, and steel materials. The results show that the grains are refined and the mechanical properties are significantly improved.

[0003] Among them, when metal materials are subjected to torsional grinding at different temperatures and pressures, the phenomenon of grain refinement of metal materials will occur. However, the equipment used in the existing high-pressure torsion tests mainly consists of a pressure head and a die, which cannot meet the high-temperature and high-pressure torsion test requirements of some metal materials in the laboratory. The high-temperature environment will seriously affect the service life of the equipment and increase the cost of laboratory tests. In a high-temperature environment, it is impossible to ensure the reliable operation of the equipment, which in turn affects the high-pressure torsion test results of metal materials. In addition, in a high-temperature environment, metal materials are easily adhered to the die, increasing the difficulty of disassembling the die, that is, increasing the difficulty of separating the metal material from the die.

[0004] In summary, the existing high-pressure torsion equipment cannot meet the high-temperature and high-pressure torsion test requirements while operating reliably and not affecting the service life of the equipment. Summary of the Utility Model

[0095] The present utility model provides a high-temperature and high-pressure torsion device suitable for performing torsion tests on a workpiece 90.

[0096] Among them, the material of the workpiece 90 includes but is not limited to aluminum alloy, copper alloy, titanium alloy, composite material or steel material. In this embodiment, the material of the workpiece 90 is titanium alloy. The workpiece 90 is a test specimen.

[0097] Please refer to Figures 1 to 3As shown in the figure, the high-temperature and high-pressure torsion device includes a stamping mechanism 10, a pressurizing mechanism 20, a torsion mechanism 30, a heating mechanism 40, a cooling mechanism 50, a control mechanism 60, an auxiliary mechanism 70, and a frame mechanism 80. The stamping mechanism 10 includes a first stamping component, a second stamping component, and a demolding component. The pressing ends of the first stamping component and the second stamping component are respectively adapted to be inserted into both ends of the demolding component and cooperate with the inner cavity of the demolding component to form a cavity for placing the workpiece 90. The pressurizing mechanism 20 and the torsion mechanism 30 are arranged on the frame mechanism 80. The driving end of the pressurizing mechanism 20 is oppositely arranged with the driving end of the torsion mechanism 30. In this embodiment, the driving end of the pressurizing mechanism 20 is adapted to be connected to the first stamping component. The driving end of the torsion mechanism 30 is adapted to be connected to the second stamping component. The demolding component is adapted to be sleeved on the outer peripheral side of the pressing end of the first stamping component. The heating end of the heating mechanism 40 is adapted to surround the outer periphery of the demolding component to heat the cavity, and further heat the workpiece 90 in the cavity. The cooling mechanism 50 is respectively arranged around the outer peripheries of the pressurizing mechanism 20 and the torsion mechanism 30 to cool the pressurizing mechanism 20 and the torsion mechanism 30 to protect the pressurizing mechanism 20 and the torsion mechanism 30.

[0098] The control mechanism 60 is adapted to control the heating mechanism 40 to heat the workpiece 90, control the pressurizing mechanism 20 to pressurize the workpiece 90, and control the torsion mechanism 30 to twist the workpiece 90; the control mechanism 60 is also adapted to control the cooling mechanism 50 to cool the pressurizing mechanism 20 and the torsion mechanism 30.

[0099] The auxiliary mechanism 70 is adapted to be sleeved on the outer periphery of the demolding component when the workpiece 90 adheres to the inner cavity to assist the separation of the first stamping component, the second stamping component, and the demolding component.

[0100] In this embodiment, when the demolding component is sleeved on the outer peripheral side of the pressing end of the first stamping component, the workpiece 90 is placed in the inner cavity of the demolding component. Thereafter, the control mechanism 60 first controls the pressurizing mechanism 20 to drive the pressing end of the first stamping component to insert into the inner cavity of the demolding component so that the workpiece 90 is placed in the cavity; the control mechanism 60 then controls the heating mechanism 40 to heat. During this period, the control mechanism 60 simultaneously controls the cooling mechanism 50 to cool the pressurizing mechanism 20 and the torsion mechanism 30 respectively. When the heating mechanism 40 heats the workpiece 90 to the test temperature, the workpiece 90 is kept warm. Thereafter, the control mechanism 60 controls the pressurizing mechanism 20 to pressurize the workpiece 90 and controls the torsion mechanism 30 to twist the workpiece 90 to meet the high-pressure torsion test requirements of the torsion test of the workpiece 90.

[0101] When the workpiece 90 adheres to the inner cavity and the first stamping component, the second stamping component, and the demolding component are stuck together, the auxiliary mechanism 70 can assist in separating the first stamping component, the second stamping component, and the demolding component.

[0102] This high-temperature and high-pressure torsion device, through the cooperation of the stamping mechanism 10, the pressurizing mechanism 20, the torsion mechanism 30, the heating mechanism 40 and the cooling mechanism 50, while ensuring that the device meets the requirements of high-temperature and high-pressure torsion tests, operates reliably, effectively cools the pressurizing mechanism 20 and the torsion mechanism 30, and extends the service life of the device. By setting the auxiliary mechanism 70, when the workpiece 90 adheres to the cavity, it assists the first stamping component, the second stamping component and the demolding component to separate, improves the efficiency, and reduces the separation difficulty between the workpiece 90 and the stamping mechanism 10.

[0104] In this embodiment, the fence 81 is arranged on the top of the support frame 82.

[0105] Please refer to Figures 3 to 5 As shown, the pressurizing mechanism 20 includes a die carrier 21, a pressurizing drive device 22, a movable pressure plate 23, a first heat insulation plate 24, a punch 25 and a displacement sensor 28. The die carrier 21 is arranged on the top of the support frame 82. In this embodiment, the die carrier 21 includes a top plate, a bottom plate and left and right side plates. The top plate, the bottom plate and the left and right side plates enclose a hollow cavity. The movable pressure plate 23 is slidably arranged up and down on the die carrier 21 and is located in the hollow cavity. Specifically, a guide sleeve 211 is vertically arranged on the top plate of the die carrier 21. The pressurizing mechanism 20 further includes a guide post 26 slidably matched with the guide sleeve 211.

Specifically, the driving end of the pressure driving device 22 is installed on the top of the movable pressing plate 23. The upper end of the punch head 25 is installed at the bottom of the movable pressing plate 23. The lower end of the punch head 25 is connected to the first stamping assembly, and the first stamping assembly is located in the hollow cavity of the die set 21. A first heat insulation plate 24 is arranged between the movable pressing plate 23 and the punch head 25, which is used to protect the driving end of the pressure driving device 22 to prevent the driving end of the pressure driving device 22 from being heated. The cooling mechanism 50 is respectively arranged around the driving end of the pressure driving device 22 and the outer peripheral side of the first heat insulation plate 24, which is used to further protect the driving end of the pressure driving device 22. The displacement sensor 28 is arranged on the die set 21 and is suitable for detecting the displacement of the punch head 25. The control mechanism 60 is suitable for controlling the pressure driving device 22 to drive the punch head 25 to lift according to the detection result of the displacement sensor 28, so that the pressure applied by the punch head 25 to the workpiece 90 meets the test requirements, that is, controlling the pressure driving device 22 to drive the punch head 25 to perform precise pressing.

[0107] The displacement sensor 28 includes but is not limited to a displacement scale, etc. In this embodiment, the displacement sensor 28 includes a fixed part 281 and a movable part 282. Among them, the fixed part 281 is installed on the side plate of the die set 21. The movable part 282 is installed on the edge of the movable pressing plate 23. When the movable pressing plate 23 moves up and down, the fixed part 281 measures the displacement change of the movable pressing plate 23 through the cooperation with the movable part 282, and then obtains the displacement change of the punch head 25. Among them, the displacement sensor 28 is a prior art, so it will not be elaborated.

[0108] Further, please refer to Figure 5 As shown, the pressing mechanism 20 further includes a buffer block 27. The buffer block 27 is sleeved on the guide post 26 and is fixed on the top of the guide sleeve 211.

The guiding frame 291 is fixed to the top of the top plate of the die carrier 21. A vertically arranged notch is formed in the guiding frame 291. The rack 292 extends in the vertical direction, that is, the length direction of the rack 292 is parallel to the lifting direction of the movable pressing plate 23. The lower end of the rack 292 is arranged on the movable pressing plate 23, and the upper end of the rack 292 slidably passes through the notch and extends outside the guiding frame 291. The locking driving device 294 is installed on the guiding frame 291, and the driving end of the locking driving device 294 is connected to the wedge-shaped block 293. The control mechanism 60 is adapted to control the locking driving device 294 to drive the wedge-shaped block 293 to move in the first direction (i.e., the horizontal direction) so that the wedge-shaped block 293 meshes with or separates from the rack 292. The first direction is perpendicular to the length direction of the rack 292.

[0110] When the high-temperature and high-pressure torsion device is working, the locking driving device 294 drives the wedge-shaped block 293 to separate from the rack 292 so that the movable pressing plate 23 can be lifted and lowered. When the high-temperature and high-pressure torsion device is in an idle state, the locking driving device 294 drives the wedge-shaped block 293 to mesh with the rack 292 so that the movable pressing plate 23 cannot be lifted and lowered, thereby preventing the movable pressing plate 23 from making accidental movements, preventing accidental injury to workers, and improving safety performance.

[0125] In this embodiment, the working principle of the high-temperature and high-pressure torsion device is as follows:

[0126] Install the lower punch 16 on the quick-change lower die 15, and then fit the split demoulding ring 18 around the pressure-applying end of the lower punch 16 to form a ring, and sleeved the tensioning outer ring 19 around the split demoulding ring 18, so as to form the inner cavity of the demoulding assembly in the inner ring of the split demoulding ring 18;

[0127] Place the workpiece 90 in the inner cavity of the demoulding assembly;

[0128] Install the upper die base 11 on the pressing head 25, install the upper punch 14 on the quick-change upper die 13, and then connect the upper and lower ends of the guiding block 12 to the upper die base 11 and the quick-change upper die 13 respectively;

[0129] The control mechanism 60 controls the pressurizing driving device 22 to drive the quick-change upper die 13 to move downward, so that the upper die base 11 and the quick-change upper die 13 are inserted under the guidance of the guiding block 12;

[0130] Wait for the control mechanism 60 to control the pressurizing driving device 22 to indirectly drive the upper punch 14 to move downward, so that the pressure-applying end of the upper punch 14 is inserted into the upper end of the demoulding assembly to form a cavity; thereafter, the pressurizing driving device 22 stops operating;

[0131] The control mechanism 60 controls the induction heating coil 41 to heat the outer periphery of the demolding assembly, so as to heat the workpiece 90 in the cavity; during this period, the control mechanism 60 simultaneously controls the cooling mechanism 50 to cool the pressurizing mechanism 20 and the torsion mechanism 30 respectively.

[0132] When the induction heating coil 41 heats the workpiece 90 to the test temperature, the control mechanism 60 controls the induction heating coil 41 to keep the workpiece 90 warm;

[0133] After that, the control mechanism 60 controls the pressurizing drive device 22 to drive the upper punch 14 to pressurize the workpiece 90, and controls the torsion drive device 32 to drive the lower punch 16 to twist the workpiece 90, so as to meet the high-pressure torsion test requirements of the torsion test of the workpiece 90;

[0134] After the torsion test is completed, the control mechanism 60 controls the induction heating coil 41 and the torsion drive device 32 to stop operating, and then controls the pressurizing drive device 22 to indirectly drive the upper punch 14 to move upward;

[0135] The upper punch 14 is disassembled from the inner cavity of the split demolding ring 18, then the auxiliary tensioning outer ring 19 is separated from the split demolding ring 18, and finally the split demolding ring 18 is separated from the lower punch 16, so that the staff can take out the tested workpiece 90.

[0136] Furthermore, please refer to Figure 14 and Figure 15 As shown, when the workpiece 90 adheres to the inner cavity and causes the upper punch 14, the lower punch 16, the tensioning outer ring 19 and the split demolding ring 18 to adhere together, the auxiliary mechanism 70 is adapted to be sleeved on the outer periphery of the tensioning outer ring 19 to assist the separation of the tensioning outer ring 19 from the split demolding ring 18.

[0137] Specifically, the auxiliary mechanism 70 includes a support outer ring 71 and a connecting sleeve 72. Among them, the inner hole of the support outer ring 71 includes a large-diameter end and a small-diameter end arranged coaxially. The large-diameter end and the small-diameter end of the support outer ring 71 are communicated with each other. The inner diameter of the small-diameter end of the support outer ring 71 is larger than the outer diameter of the split demolding ring 18. The outer diameter of the connecting sleeve 72 is less than or equal to the inner diameter of the small-diameter end of the support outer ring 71.

[0138] When the upper punch 14, the lower punch 16, the tensioning outer ring 19 and the split demolding ring 18 adhere together, the support outer ring 71 is adapted to be sleeved on the outer periphery of the tensioning outer ring 19, and the connecting sleeve 72 is adapted to be sleeved on the upper punch 14 and contact the split demolding ring 18, so that the staff can apply pressure to the tensioning outer ring 19 from the large-diameter end through the connecting sleeve 72 to separate the tensioning outer ring 19 from the split demolding ring 18.

[0139] In this embodiment, the working principle of the auxiliary mechanism 70 is as follows:

[0140] When the workpiece 90 adheres to the cavity, that is, the tested workpiece 90 adheres the upper punch 14, the lower punch 16 and the split demoulding ring 18 together, so that the tension outer ring 19 and the split demoulding ring 18 cannot be separated, place the split demoulding ring 18 inside the large-diameter end of the support outer ring 71; at this time, the support outer ring 71 is vertically arranged, and the large-diameter end of the support outer ring 71 is above the small-diameter end.

[0141] Then sleeved the connecting sleeve 72 on the upper punch 14, and its lower end surface is in contact with the top surface of the split demoulding ring 18;

[0142] Apply a downward force to the connecting sleeve 72 to separate the tension outer ring 19 and the split demoulding ring 18; among them, the downward force can be applied to the connecting sleeve 72 by the pressurizing mechanism 20, or the downward force can be applied to the connecting sleeve 72 manually by the staff.

[0143] After the split demoulding ring 18 is separated from the tension outer ring 19, the staff can separate the workpiece 90, the upper punch 14, the lower punch 16 and the split demoulding ring 18.

[0144] Through the cooperation of the stamping mechanism, the pressurizing mechanism, the torsion mechanism, the heating mechanism and the cooling mechanism, the utility model runs reliably while ensuring that the equipment meets the requirements of high-temperature and high-pressure torsion tests, effectively cools the pressurizing mechanism and the torsion mechanism, and prolongs the service life of the equipment. When the workpiece adheres to the cavity, by adding an auxiliary mechanism to assist the separation of the first stamping component, the second stamping component and the demoulding component, the efficiency is improved and the separation difficulty between the workpiece and the stamping mechanism is reduced. Through the cooperation of the split demoulding ring and the tension outer ring, the demoulding component is convenient for quick disassembly, the operation is simple, and the work efficiency is improved.

[0145] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
