Description
Technical Field
[0001] The invention relates to the technical field of titanium alloy product processing, in particular to a titanium alloy die forging heat treatment device. Background Art
[0002] Titanium alloy die forgings are parts made of titanium alloy materials through die forging technology. Titanium alloys are widely used for their excellent mechanical properties, corrosion resistance and low density, especially in aerospace, automobile, medical and other fields. In order to ensure the structural strength and service life of titanium alloy die forgings, they need to be subjected to stress relief annealing after forging, so as to reduce the internal stress generated during the processing, prevent the workpiece from deformation or cracking, and ensure the performance and life of the workpiece.
[0003] When stress relief annealing is performed on a larger sheet-shaped titanium alloy die forging, the sheet is usually placed horizontally in the annealing furnace, and inert gas is continuously introduced during the annealing process to prevent the sheet from undergoing oxidation reaction under high temperature conditions. Since the sheet is placed directly inside the annealing furnace, the bottom of the sheet is kept in contact with the annealing furnace. Due to the poor thermal conductivity of the titanium alloy, the uniform heating of the sheet will be limited, thereby affecting the annealing effect of the sheet. In view of the above problems, there are better solutions in the prior art. The sheet is placed overhead so that the upper and lower surfaces of the sheet are exposed to the inert gas, which can reduce the contact area between the bottom of the sheet and the annealing furnace, thereby improving the heat conduction efficiency and thus improving the annealing effect. However, there are still the following problems: when the sheet is large, the overhead setting will cause the sheet to bend due to its own gravity, thereby affecting the mechanical properties of the sheet, and the position of the sheet in the annealing furnace is fixed. When the heat in the annealing furnace is unevenly distributed and local cold spots appear, it still affects the uniform heating effect of the sheet, thereby affecting the annealing effect of the sheet.
[0004] Therefore, in order to solve the problem that the sheet bends due to its own gravity during annealing and the sheet is fixed in the annealing furnace, which affects the annealing effect of the sheet, a titanium alloy die forging heat treatment equipment is proposed. Summary of the invention
[0005] The purpose of the present invention is to provide a heat treatment equipment for titanium alloy die forgings, which solves the problem that the sheet is bent due to its own gravity during annealing, and the flow of inert gas affects the uniform heating of the sheet, thereby affecting the annealing effect of the sheet. Through the centralized heating of the inert gas inside the annealing furnace, the heated inert gas is blown to the lower surface of the sheet, and the horizontal position of the sheet inside the annealing furnace is continuously adjusted under the action of the driving mechanism 1 and the driving mechanism 2, so that the uniform heating of the sheet is achieved while effectively ensuring the annealing effect of the sheet.
[0006] To achieve the above object, the present invention provides the following technical solutions:
[0007] A titanium alloy die forging heat treatment equipment comprises an annealing furnace and a heating component, wherein the heating component is arranged inside the annealing furnace, and further comprises a rotating rod, a rectangular frame, a placing roller, a hollow block, a coil, a mounting piece, a rubber tube, a driving mechanism 1 and a driving mechanism 2, wherein the rectangular frame is arranged in the annealing furnace, the placing roller is rotatably arranged in the rectangular frame, one end of the rotating rod is rotatably connected to the inner wall of the annealing furnace, the hollow block is arranged below the rectangular frame, a plurality of air outlet holes are opened on the top of the hollow block, the coil is arranged below the heating component, the mounting piece is arranged inside the annealing furnace, the coil is connected to the inner wall of the annealing furnace through the mounting piece, the front end of the coil is connected to the rubber tube, the lower end of the rubber tube penetrates into the inside of the hollow block, the driving mechanism 1 is arranged on the rectangular frame and connected to the rotating rod, and when the rotating rod rotates, the driving mechanism 1 drives the rectangular frame to move left and right, and the driving mechanism 2 is arranged on the hollow block, and when the rotating rod rotates, the driving mechanism 2 drives the rectangular frame and the hollow block to move forward and backward.
[0008] By adopting the above scheme, during the annealing process, when the rotating rod rotates, the driving mechanism 1 and the driving mechanism 2 can be used to drive the rectangular frame to drive the sheet to move back and forth in the front, back, left and right directions, thereby continuously adjusting the position of the sheet in the annealing furnace. At the same time, the continuous movement of the rectangular frame can be used to disturb the heat in the annealing furnace, so that the heat in the annealing furnace can be evenly dispersed, avoiding the occurrence of local cold spots in the annealing furnace, and thus effectively ensuring the annealing effect of the sheet.
[0009] Preferably, the driving mechanism 1 includes a motor, a telescopic rod, a connecting plate, a slider, a U-shaped rod, a driving plate, a driving rod and a disc, the motor is arranged outside the annealing furnace, the rear end of the rotating rod passes through the annealing furnace and is connected to the output end of the motor, the two ends of the telescopic rod are respectively connected to the rectangular frame and the connecting plate, the slider is arranged on the side wall of the connecting plate and is sleeved with the U-shaped rod, the U-shaped rod is arranged on the inner wall of the annealing furnace, the driving plate is arranged at the bottom of the rectangular frame, and a strip opening is opened inside, the driving rod is passed through the inside of the strip opening and is connected to the disc, and the disc is sleeved with the rotating rod.
[0010] By adopting the above scheme, the driving rod can drive the rectangular frame to move back and forth in the left and right directions through the driving rod in the process of following the rotation of the disc, and then the position of the sheet in the left and right directions can be continuously adjusted to avoid the situation where local cold spots appear inside the annealing furnace and uneven heating occurs. In addition, in the process of the rectangular frame moving back and forth left and right, the position of the air outlet can be continuously adjusted, and then the position of the inert gas when it is blown out from the air outlet can be continuously adjusted, so that the inert gas can achieve a turbulent effect after entering the annealing furnace, thereby avoiding the occurrence of local cold spots and effectively ensuring the uniform heating effect of the sheet.
[0011] Preferably, the second driving mechanism includes a driving block and an L-shaped rod, the rod wall of the rotating rod is provided with a reciprocating thread, the driving block is arranged at the bottom of the hollow block, the driving block is threadedly sleeved with the rotating rod through the reciprocating thread, the L-shaped rod is arranged inside the annealing furnace, the two ends of the L-shaped rod are respectively connected to the outer wall of the hollow block and the fixed end of the telescopic rod, and the length of the reciprocating thread is smaller than the length of the driving rod.
[0012] By adopting the above scheme, since the two sides of the hollow block are connected to the fixed ends of the corresponding telescopic rods through L-shaped rods respectively, during the rotation of the rotating rod, the hollow block can be driven to reciprocate in the front and rear directions by utilizing the sleeve connection between the driving block and the reciprocating thread, so that the position of the sheet in the front and rear directions can be continuously adjusted, thereby preventing the upper part of the sheet from being blocked by the coil and affecting the heating effect, thereby ensuring uniform heating and achieving the purpose of ensuring the annealing effect.
[0013] Preferably, the rear end of the coil penetrates to the outside of the annealing furnace and is sleeved with a heat insulating sleeve, an air inlet pipe is penetrated through the side wall of the heat insulating sleeve, and an air outlet pipe is penetrated through the rear lower end of the annealing furnace.
[0014] By adopting the above solution, since the rotating rod directly passes through the annealing furnace from the inside to the outside, part of the heat will be conducted out of the annealing furnace, and under the effect of the heat insulating sleeve, the heat loss can be effectively reduced.
[0015] Preferably, the motor is arranged on the outer wall of the heat insulating sleeve, the rotating rod is sleeved with the heat insulating sleeve, a heat conducting impeller is arranged inside the heat insulating sleeve, and the heat conducting impeller is rotatably sleeved with the rod wall of the rotating rod.
[0016] By adopting the above scheme, since the rear end of the rotating rod is directly connected to the output end of the motor, thereby affecting the normal operation of the motor, under the action of the heat-conducting impeller, the heat on the surface of the rotating rod can be guided and dispersed to the inside of the heat-insulating sleeve, and in the process of the inert gas entering the coil from the air inlet pipe, the inert gas can be preheated. On the one hand, the temperature drop caused by the inert gas when entering the coil inside the annealing furnace is reduced; on the other hand, energy consumption can be reduced, and cooling protection of the rear end of the rotating rod and the motor can be achieved.
[0017] Preferably, the heating assembly is arranged at the top of the annealing furnace, the coil is arranged between the heating assembly and the rectangular frame, and when the driving rod is at the bottom, the left and right side walls of the rectangular frame are at equal distances from the left and right side walls of the heating assembly.
[0018] By adopting the above solution, the deformation of the sheet due to thermal stress during the annealing process can be reduced, which is beneficial to maintaining the flatness of the sheet, especially for thinner sheets, avoiding warping during the heating process.
[0019] Preferably, a spoiler hole is opened inside the disc, the axis of the spoiler hole is arranged parallel to the axis of the rotating rod, and the apertures of both ends of the spoiler hole are arranged in a gradual manner.
[0020] It can be seen that the inert gas will be discharged through the outlet pipe after entering the annealing furnace. During the annealing process, the hot air flow will rise, while the cold air flow will sink, forming a cycle. Such flow will cause heat to accumulate in certain areas of the annealing furnace. Since the apertures at both ends of the spoiler holes are different, the air flow will experience acceleration and deceleration after passing through different spoiler holes, thereby further achieving the spoiler effect and avoiding the occurrence of local cold spots in the annealing furnace due to heat accumulation.
[0021] Preferably, a flange is provided on the top of the rectangular frame, and the top of the flange is higher than the placement roller.
[0022] By adopting the above scheme, the two flanges can be used to block the two ends of the sheet placed on multiple placement plates, thereby preventing the sheet from being misaligned with the rectangular frame when the rectangular frame moves left or right, thereby preventing the ends of the sheet from being deformed due to their own gravity after passing through the rectangular frame.
[0023] Preferably, a plurality of annular grooves are provided on the surface of the placement roller at equal distances along the axial direction, and each of the air outlet holes is located directly below the corresponding annular groove.
[0024] By adopting the above scheme, the heated inert gas can be blown out from the inside of the air hole and directly blown to the lower surface of the sheet, which can avoid the placement of the roller to block the air hole, and under the action of the annular groove, the inert gas can be smoothly blown out from the side of the bottom of the sheet, avoiding the situation where the sheet is blown due to excessive wind pressure.
[0025] Preferably, the surface of the placement roller is in contact with the top of the hollow block, and the top of the placement roller is frosted.
[0026] By adopting the above scheme, since the position of the hollow block in the left and right directions is fixed, under the action of the friction between the placement roller and the hollow block, when the placement roller moves left and right, it can rotate autonomously, thereby driving the sheet on the placement roller to move in the left and right directions, and then can continuously adjust the contact position between the bottom of the sheet and the placement roller, thereby further ensuring uniform heating of the sheet and improving the stress relief annealing effect of the sheet.
[0027] Compared with the prior art, the present invention has the following beneficial effects:
[0028] 1. By setting the coil, rubber tube and the air outlet at the top of the hollow block, the inert gas can be heated by the heating component during the flow inside the coil, and the heated inert gas can be ejected from the air outlet to the lower surface of the sheet after entering the hollow block, thereby guiding the heat to the bottom of the sheet, reducing the uneven heating of the sheet caused by unilateral heating, thereby ensuring the annealing effect of the sheet.
[0029] 2. By setting up a driving mechanism 1, the rectangular frame can be driven to reciprocate in the left and right directions during the operation of the motor, and under the action of the friction between the placement roller and the hollow block, the sheet and the placement roller can be driven to move relative to each other, thereby realizing continuous adjustment of the sheet in the left and right directions inside the annealing furnace, and in the process of adjustment, the contact point between the bottom of the sheet and the placement roller can be continuously adjusted, avoiding the problem that the contact point between the bottom of the sheet and the annealing furnace is fixed, resulting in limited heat conduction, which in turn affects the uniform heating of the sheet and limits the annealing effect of the sheet, thereby effectively ensuring the annealing effect of the sheet.
[0030] 3. By setting up the second driving mechanism, during the rotation of the rotating rod, the reciprocating thread on the surface of the rotating rod can be connected with the thread of the driving block, so that the driving block can drive the hollow block to move back and forth in the front and rear directions, and then under the action of the L-shaped rod, the rectangular frame can be driven to move back and forth in the front and rear directions, thereby achieving the effect of driving the sheet to move back and forth in the front and rear directions, so that the position of the sheet under the coil is continuously adjusted, avoiding the uneven heating of the upper surface of the sheet due to the obstruction of the coil, and the continuous movement of the rectangular frame in four directions can have a disturbing effect on the inside of the annealing furnace, avoiding the occurrence of local cold spots, thereby further ensuring the annealing effect of the sheet.

There are multiple placement rollers 5, and the distance between two adjacent placement rollers 5 is equal, which can reduce the contact area between the bottom of the sheet and the annealing furnace 1 after the sheet is placed, and the multi-point support effect can prevent the sheet from bending and deforming due to its own gravity. The inert gas flows inside the coil 7 and enters the interior of the hollow block 6 after being heated by the heating component 2. After gathering inside the hollow block 6, it is sprayed from multiple air outlets 61 to the lower surface of the sheet, thereby achieving simultaneous heating of both sides of the sheet, effectively ensuring uniform heating of the sheet, and then ensuring the annealing effect of the sheet.
[0043] As an embodiment of the present invention, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The driving mechanism 10 is arranged on the rectangular frame 4 and connected to the rotating rod 3. When the rotating rod 3 rotates, the driving mechanism 10 drives the rectangular frame 4 to move left and right. The driving mechanism 10 includes a motor 101, a telescopic rod 102, a connecting plate 103, a slider 104, a U-shaped rod 105, a driving plate 106, a driving rod 107 and a disc 108. The motor 101 is arranged outside the annealing furnace 1. The rear end of the rotating rod 3 passes through the annealing furnace 1 and is connected to the output end of the motor 101. The two ends of the telescopic rod 102 are respectively The driving plate 106 is arranged at the bottom of the rectangular frame 4 and has a strip-shaped opening 1061 therein. The driving rod 107 is passed through the strip-shaped opening 1061 and is connected to the disc 108. The disc 108 is sleeved with the rotating rod 3. The surface of the placing roller 5 is fitted with the top of the hollow block 6, and the top of the placing roller 5 is frosted.
[0044] Since the rear end of the rotating rod 3 is connected to the output end of the motor 101, when the motor 101 is working, the output end of the motor 101 can directly drive the rotating rod 3 to rotate, and during the rotation of the rotating rod 3, the disc 108 can be driven to drive the driving rod 107 to rotate. Since the driving rod 107 is inserted into the strip-shaped opening 1061, during the rotation of the disc 108, the driving plate 106 can be driven to reciprocate in the left and right directions. The upper end of the driving plate 106 is connected to the rectangular frame 4, so the driving plate 106 can drive the rectangular frame 4 to reciprocate in the left and right directions, and then drive the sheet to reciprocate in the left and right directions. Since the surface of the placement roller 5 is in contact with the top of the hollow block 6, the friction between the placement roller 5 and the hollow block 6 can drive the sheet and the rectangular frame 4 to move relative to each other, so that the contact point between the bottom of the sheet and the placement roller 5 can be continuously adjusted, avoiding the problem of affecting the internal heat conduction efficiency of the sheet due to the fixed contact position, and further realizing uniform heating of the sheet.
[0045] As an embodiment of the present invention, refer to Figure 4 The driving mechanism 11 is arranged on the hollow block 6. When the rotating rod 3 rotates, the driving mechanism 11 drives the rectangular frame 4 and the hollow block 6 to move forward and backward. The driving mechanism 11 includes a driving block 111 and an L-shaped rod 112. The rod wall of the rotating rod 3 is provided with a reciprocating thread 31. The driving block 111 is arranged at the bottom of the hollow block 6. The driving block 111 is threadedly sleeved with the rotating rod 3 through the reciprocating thread 31. The L-shaped rod 112 is arranged inside the annealing furnace 1. The two ends of the L-shaped rod 112 are respectively connected to the outer wall of the hollow block 6 and the fixed end of the telescopic rod 102. The length of the reciprocating thread 31 is less than the length of the driving rod 107.
[0046] Since a reciprocating thread 31 is provided on the rod wall of the rotating rod 3, and the reciprocating thread 31 is threadedly sleeved with the driving block 111, the two sides of the hollow block 6 are respectively connected to the fixed ends of the corresponding telescopic rods 102 through the L-shaped rods 112 to achieve a limiting effect. During the rotation of the rotating rod 3, the driving block 111 can drive the hollow block 6 to move in the front and rear directions. Since the two ends of the telescopic rod 102 are respectively connected to the rectangular frame 4 and the connecting plate 103, and the connecting plate 103 is connected to the U-shaped rod 105 through the slider 104, the rectangular frame 4 can be driven to reciprocate in the front and rear directions during the forward and backward movement of the hollow block 6, so that the position of the sheet under the coil 7 can be continuously adjusted, thereby avoiding the uneven heating of the upper surface of the sheet due to the obstruction of the coil 7.
[0047] As an embodiment of the present invention, refer to Figure 5 and Figure 6The rear end of the coil 7 passes through the outside of the annealing furnace 1 and is sleeved with a heat insulating sleeve 12. The side wall of the heat insulating sleeve 12 is penetrated with an air inlet pipe 13. The lower end of the rear side of the annealing furnace 1 is penetrated with an air outlet pipe 14. The motor 101 is arranged on the outer wall of the heat insulating sleeve 12. The rotating rod 3 is sleeved with the heat insulating sleeve 12. A heat conducting impeller 121 is arranged inside the heat insulating sleeve 12. The heat conducting impeller 121 is rotatably sleeved with the rod wall of the rotating rod 3.
[0048] The instantaneous temperature of the gas is low when it enters the insulation sleeve 12 through the air inlet pipe 13, and the heat-conducting impeller 121 is sleeved with the rotating rod 3, which can absorb and disperse the rotating rod 3 from the inside of the annealing furnace 1 into the inside of the insulation sleeve 12. Therefore, the inert gas can achieve a preheating effect before entering the coil 7, thereby realizing the protection of the motor 101 and reducing the impact of the inert gas on the internal temperature of the annealing furnace 1 after entering the annealing furnace 1.
[0049] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The heating component 2 is arranged at the top of the annealing furnace 1, and the coil 7 is arranged between the heating component 2 and the rectangular frame 4. When the driving rod 107 is at the bottom, the distance between the left and right side walls of the rectangular frame 4 and the left and right side walls of the heating component 2 is equal, which can reduce the deformation of the sheet due to thermal stress during the annealing process, which is beneficial to maintaining the flatness of the sheet, especially for thinner sheets, avoiding warping during the heating process.
[0050] As an embodiment of the present invention, refer to Figure 7 A spoiler hole 1081 is opened inside the disk 108, the axis of the spoiler hole 1081 is arranged parallel to the axis of the rotating rod 3, and the apertures of both ends of the spoiler hole 1081 are arranged in a gradual manner.
[0051] It can be seen that the inert gas will be discharged through the outlet pipe 14 after entering the annealing furnace 1. During the annealing process, the hot air flow will rise, while the cold air flow will sink to form a cycle. Such flow will cause heat to accumulate in certain areas of the annealing furnace 1. Since the apertures at both ends of the spoiler holes 1081 are different, the air flow will be accelerated and decelerated after passing through different spoiler holes 1081, thereby further achieving the spoiler effect and avoiding the occurrence of local cold spots in the annealing furnace 1 due to heat accumulation.
[0052] As an embodiment of the present invention, refer to Figure 8 A flange 41 is provided on the top of the rectangular frame 4 , and the top of the flange 41 is higher than the placement roller 5 .
[0053] Since the placement roller 5 will drive the sheet and the rectangular frame 4 to move relative to each other during rotation, the end of the sheet may pass over the placement roller 5 due to inertia. At this time, the end of the sheet may sag and deform due to its own gravity, thereby affecting the quality of the sheet. The flange 41 here can be made of a high-temperature resistant rubber plate, which prevents the sheet from being misaligned with the rectangular frame 4 and avoids deformation due to collision between the sheet and the flange 41.
[0054] As an embodiment of the present invention, refer to Figure 8 The surface of the placing roller 5 is provided with a plurality of annular grooves 51 at equal distances along the axial direction, and each air outlet 61 is located directly below the corresponding annular groove 51. After the heated inert gas is blown out from the inside of the air hole, it can be directly blown to the lower surface of the sheet, which can avoid the placing roller 5 from blocking the air outlet 61. Moreover, under the action of the annular groove 51, the inert gas can be smoothly blown out from the side of the bottom of the sheet, avoiding the situation where the sheet is blown due to excessive wind pressure.
[0055] Working principle: After the inert gas enters the interior of the heat-insulating sleeve 12, it has the dual effect of cooling the rear end of the rotating rod 3 and preheating itself, thereby avoiding damage to the motor 101 and reducing the impact of the sudden drop in temperature above the sheet due to the low temperature after the inert gas enters the annealing furnace 1. After flowing, the inert gas is finally sprayed to the lower surface of the sheet, thereby achieving synchronous heating of the upper and lower surfaces of the sheet, and ensuring uniform heating of the sheet. In order to avoid the appearance of local cold spots in the annealing furnace 1, thereby affecting the annealing effect of the sheet, under the action of the driving mechanism 10 and the driving mechanism, when the motor 101 drives the rotating rod 3 to rotate, the horizontal position of the sheet can be continuously adjusted through the rectangular frame 4. At the same time, the turbulence effect formed by the rectangular frame 4 during the movement can continuously disturb the hot air flow inside the annealing furnace 1, further avoiding the appearance of local cold spots in the annealing furnace 1, thereby effectively ensuring the annealing effect of the sheet.
[0056] Specifically: the sheet to be processed is placed on the placing roller 5 and the furnace door is closed, and the inert gas is transported to the inside of the heat-insulating sleeve 12 through the air inlet pipe 13. The kinetic energy generated during the transportation of the inert gas can drive the heat-conducting impeller 121 to rotate, and the heat absorbed by the heat-conducting impeller 121 can realize the preheating of the inert gas. After entering the annealing furnace 1, the preheated inert gas can be converted into high-temperature gas under the action of the heating component 2, and finally enter the inside of the hollow block 6 and spray out from the air outlet 61, so that the inside of the hollow block 6 absorbs heat while the high-temperature gas can be sprayed to the lower surface of the sheet, thereby realizing the synchronous heating of the upper and lower surfaces of the sheet, so as to achieve the effect of uniform heating of the sheet;
[0057] Start the motor 101, and the output end of the motor 101 drives the rotating rod 3 to rotate. During the rotation of the rotating rod 3, the disc 108 is driven to rotate. Since the driving rod 107 is connected to the disc 108 and is inserted into the strip-shaped opening 1061, the driving plate 106 can be driven to move back and forth left and right during the rotation of the disc 108. The driving plate 106 is connected to the rectangular frame 4. At this time, due to the restrictions of the slider 104 and the U-shaped rod 105, the rectangular frame 4 can follow the driving plate 106 to move back and forth left and right. Since the surface of the placement roller 5 fits the top of the hollow block 6, and the surface of the placement roller 5 is frosted, the friction between the placement roller 5 and the hollow block 6 can drive the sheet and the rectangular frame 4 to move relative to each other, and the contact point between the bottom of the sheet and the placement roller 5 is continuously adjusted, thereby avoiding the situation where uniform heating is affected by poor heat conduction.
[0058] Since the two sides of the hollow block 6 are respectively connected to the fixed ends of the corresponding telescopic rods 102 through the L-shaped rods 112, during the rotation of the rotating rod 3, the driving block 111 is connected to the threaded sleeve of the rotating rod 3 through the reciprocating thread 31, and can drive the hollow block 6 to drive the rectangular frame 4 to move back and forth in the front and rear directions, thereby continuously adjusting the position of the sheet in the front and rear directions, avoiding the obstruction of the coil 7 and affecting the heating of the upper surface of the sheet, further ensuring the uniform heating effect of the sheet, and further ensuring the annealing effect of the sheet.
[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
