Description

Technical Field

[0001] The invention relates to the technical field of nonferrous metallurgy, and in particular to a quenching device for solid solution heat treatment. Background Art

[0002] As we all know, titanium and titanium alloy materials have the characteristics of low specific gravity, high strength, good heat resistance and corrosion resistance, and are widely used in the field of shipbuilding and aviation industry. Solid solution treatment of titanium and titanium alloy plates is a major means to enhance their material properties. Solid solution treatment is the process of heating, keeping warm and quickly cooling titanium and titanium alloys to room temperature. In order to quickly cool the titanium plate, a quenching method must be used, so solid solution treatment is sometimes called quenching, and the cooling method is generally water quenching.

[0003] Titanium alloys can be divided into α titanium alloys, β titanium alloys, and α+β titanium alloys according to their annealing state, among which α+β titanium alloys are the most widely used. For near-α or α+β titanium alloys, the purpose of solution treatment is to retain martensite α' and α" or a small amount of metastable β phase. After obtaining a certain proportion of primary α and β phases, the β phase will produce a metastable β phase during rapid cooling. However, due to the low carbon content of the β-stabilizing element in the α+β titanium alloy, the β-to-α rotation speed is rapid. If the titanium alloy sheet coming out of the heat treatment furnace is not put into water in time, the temperature of the product will drop rapidly, and the α phase will first nucleate on the original β phase grain boundary and grow rapidly. When the transfer speed is less than the transformation speed from β to α, it will cause the precipitation of the α phase, affecting the mechanical properties of the quenched state.

[0004] The thinner the sheet, the easier it is to cool, and the higher the transfer speed requirement.

[0005] Therefore, quenching transfer time is a key parameter for titanium alloy plates to obtain better comprehensive mechanical properties.

[0006] According to the investigation, on the existing titanium plate heat treatment production line, for the solution treatment of titanium alloy thick plates, the quenching transfer time needs to be controlled within 1 minute, and the solution treatment tooling can be used to lift the plate vertically into the water by a crane. For the solution treatment of titanium alloy thin plates, since the cooling speed of thin plates in the air is much faster than that of thick plates, they need to be quickly put into the water within 2-3 seconds after being taken out of the furnace. It is necessary for a dedicated person to hold a special fixture to quickly drag the titanium alloy plate out of the furnace into the quenching water tank next to it. This method has a low degree of automation and safety factor, high labor intensity, and unstable product quality. Summary of the invention

DETAILED DESCRIPTION

[0033] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0034] Reference Figure 1 As shown, a quenching device for solution heat treatment in an embodiment of the present invention comprises an accelerating roller, a quenching tank 1, a fixed frame 2, a lifting frame 8, a lifting mechanism, a discharge roller 24, a hot metal detector 15 and a cold metal detector 23, the quenching tank 1 is arranged behind the furnace door of the heat treatment furnace, the hot metal detector 15 is arranged at the discharge end of the heat treatment furnace, the fixed frame 2 is arranged at the upper end of the quenching tank 1, the lifting frame 8 is arranged above the quenching tank 1, the lifting frame 8 is connected to the fixed frame 2 through the lifting mechanism, a driving roller is arranged at the bottom of the lifting frame 8, and the lifting mechanism drives the lifting frame 8 to move up and down relative to the fixed frame 2 and the quenching tank 1, the accelerating roller and the discharge roller 24 are respectively arranged at the titanium plate inlet end and the titanium plate outlet end of the quenching tank 1, the baffle mechanism is arranged between the driving roller and the quenching tank, and the accelerating roller The input end of the conveyor belt is docked with the discharge end of the heat treatment furnace; in this embodiment, the material is a titanium plate. When the titanium plate is about to be taken out of the furnace, the lifting mechanism drives the lifting frame 8 to move down to a low position in advance, and the transmission roller sinks into the quenching tank 1. The baffle 11 swings at an appropriate angle driven by the hydraulic cylinder 9. After the high-temperature titanium plate is taken out of the furnace, it slides onto the baffle 11 slide rail through the acceleration roller, directly rushes into the quenching tank and falls on the transmission roller until it is completely immersed. After the titanium plate is cooled, the lifting mechanism drives the lifting frame 8 to rise and move to a high position, and the output end of the transmission roller is docked with the input end of the discharge roller 24. At this time, the roller surface of the transmission roller is flush with the roller surface of the discharge roller 24. The hot metal detector 15 and the cold metal detector 23 are both arranged at the upper end of the fixed frame 2, respectively located on the titanium plate feeding side and the discharging side of the quenching tank 1, and a signal is sent when a titanium plate passes through.

[0035] For titanium alloy thin plates, in order to shorten the quenching transfer time as much as possible, a set of accelerating rollers is set at the discharge end of the heat treatment furnace. When the hot metal detector 15 at the discharge end of the heat treatment furnace detects the titanium alloy plate, the lifting frame 8 of the quenching device drops to the limit position, and the lifting baffle 11 rises and sends a signal. After the furnace door is opened, the titanium alloy thin plate rushes out quickly under the drive of the accelerating roller, and directly rushes into the water tank relying on its own initial velocity and inertia, and falls into the lifting frame 8 that has been lowered into place in advance. By controlling parameters such as the linear speed of the accelerating roller, the quenching transfer time is controlled within 3s. After a period of time, the lifting mechanism of the quenching device will remove the quenched titanium alloy thin plate from the water tank, and then the high-position transmission motor will drive the flower roller to rotate through the centralized chain drive to send the plate to the next process.

[0036] For titanium alloy thick plates, the lifting frame 8 of the quenching mechanism is always kept at a high position, and the titanium alloy plate passes through the quenching device quickly through the acceleration roller. A locking mechanism is provided on the quenching device, and the locking mechanism clamping block tightly connects the lifting frame 8 with the fixed frame 2. The locking mechanism is provided with a buffer device and a self-clamping device to alleviate the impact that the titanium alloy thick plate may cause to the lifting frame 8 during the rapid advancement of the titanium alloy thick plate through the acceleration roller. After the titanium alloy thick plate enters the lifting frame of the lifting area of ​​the unloading roller 24, it is vertically lifted into the quenching tank 1 by a special crane in the workshop, and the entire quenching transfer time is controlled within 1 minute.

[0037] Furthermore, the baffle mechanism includes a baffle and a hydraulic cylinder 9. The baffle 11 is arranged on the titanium plate entrance side of the quenching tank 1. One end of the baffle is hinged to the fixed frame 2 through a hinge shaft. The hydraulic cylinder 9 has a displacement sensor at the tail end, which is connected to the baffle through a crank 10, driving the baffle to rotate to different angles around the hinge shaft, so as to control materials of different specifications to always slide into the quenching tank along the baffle and be completely immersed in the quenching liquid.

[0038] Furthermore, a copper slide rail is provided on the baffle plate to reduce the contact area between the titanium plate and the baffle plate, and the end of the rail is rounded to prevent the titanium plate from being scratched during the sliding process.

[0039] Furthermore, limit plates are arranged on both sides of the baffle plate to prevent the titanium plate from rushing out of the lifting frame during the falling process.

[0040] Furthermore, the transmission roller table includes a plurality of transmission rollers horizontally arranged in sequence along the conveying direction of the titanium plate, and a transmission mechanism connected to each transmission roller, and the transmission mechanism drives the transmission roller to rotate.

[0041] Furthermore, the transmission mechanism includes a transmission motor disposed on the upper part of the lifting frame 8, the transmission motor is connected to each transmission roller through a chain, driving each transmission roller to rotate synchronously, and a tensioner is disposed on the lifting frame 8 for adjusting the tightness of the chain;

[0042] The transmission roller is a hollow flower roller, and a chain track pressure plate is provided on the transmission side of the transmission roller to prevent the chain from jumping teeth.

[0043] Furthermore, the quenching tank 1 is a stainless steel frame structure, a plurality of cold water inlet points are arranged at the lower part of the tank body of the quenching tank 1, an overflow tank 3 is arranged at the upper part, and a horizontal flow sedimentation tank is arranged at one side of the overflow tank 3;

[0044] The quenching tank 1 is provided with cold water for stirring.

[0045] Furthermore, the fixed frame 2 is a steel platform-type structural member, and four columns are located on the side walls of the quenching tank 1, and anti-slip ribs are provided at the bottom of the columns.

[0046] Furthermore, the lifting frame 8 is a cage-type steel structure, and the top is connected to the lifting mechanism through four connecting rods. The horizontality can be ensured by adjusting the elevation of four points of the lifting frame 8.

[0047] Furthermore, the lifting mechanism includes a lifting motor 4, a transmission assembly and multiple spiral elevators 7 arranged on the lifting frame 8. The lifting motor 4 is connected to each spiral elevator 7 through a gear transmission assembly. The nut sleeved on the spiral elevator 7 is connected to the fixed frame 2. The lifting motor 4 drives each spiral elevator 7 to move synchronously through the transmission assembly.

[0048] Furthermore, the transmission assembly includes a steering gear and a coupling. The lifting motor 4 is connected to the plurality of screw elevators 7 via the steering gear and the coupling, thereby driving the screw elevators 7 to move synchronously up and down.

[0049] Furthermore, the number of the spiral elevators 7 is four.

[0050] Furthermore, the steering gear is a bevel gear steering gear.

[0051] Furthermore, protective plates 12 or protective nets are provided on both sides of the lower end of the lifting frame 8 to prevent the titanium plate from rushing out of the lifting frame 8 during the sliding process; an anti-collision plate 13 or anti-collision net is provided at the bottom of the lifting frame 8, and the anti-collision plate 13 or anti-collision net is arranged directly below the roller surface of the transmission roller to prevent the titanium plate from being stuck between the transmission flower rollers during the sliding process, or to prevent the titanium plate from being vertically inserted between the flower rollers.

[0052] Furthermore, the protection plate 12 and the anti-collision plate 13 are both in the form of sieve plates, which enhance the heat exchange during the quenching process.

[0053] Furthermore, the quenching device for solution heat treatment also includes a locking mechanism, which includes a suspension beam 16, an inclined sliding block 17, a pressure head 18 and a buffer support 19. The inclined sliding block is suspended on the fixed frame 2 through the suspension beam 16, and the pressure head is installed on the lifting frame 8 to complete the lifting movement with the lifting frame; when the lifting frame 8 rises to a high position, the inclined sliding block contacts and presses the pressure head.

[0054] The inclined sliding block and the pressure head form a wedge-shaped structure. As the lifting frame 8 rises higher, the pressure applied by the pressure head to the inclined sliding block becomes greater. When the lifting frame 8 rises to the limit position, the inclined sliding block and the pressure head are automatically pressed together to form a self-pressing structure.

[0055] The horizontal distance between the buffer support 19 and the inclined sliding block can be adjusted by bolts. The guiding inclination angle of the inclined sliding block itself is 45 degrees. By adjusting the distance between the buffer support and the inclined sliding block, the roller surface elevation of the transmission roller can be controlled when the lifting frame stops at a high position. The roller surface elevation of the transmission roller should be kept consistent with the roller surface elevation of the unloading roller as much as possible.

[0056] The buffer support is equipped with a buffer device to alleviate the impact of the titanium plate on the lifting frame caused by the elevation difference when the titanium plate passes through the transmission roller.

[0057] The working principle of the present invention is as follows: Figure 1 As shown, a quenching device for solution heat treatment of the present invention is located directly above the quenching tank 1, and four columns of the fixed frame 2 are located directly above the wall of the quenching tank 1. Hot water overflows to the horizontal flow sedimentation tank through the overflow tank 3.

[0058] Figure 2 The working state of the quenching device shown is the low-position working state during thin plate quenching. When the titanium plate arrives at the furnace door, the material detection switch sends a signal, the quenching device lifting motor 4 starts, and drives four screw elevators 7 to move synchronously through the coupling group 5 and the bevel gear steering group 6, so that the quenching device lifting frame 8 sinks into the quenching tank 1. After the lifting frame reaches the working position, the hydraulic cylinder 9 drives the crank 10 to drive the connecting shaft to rotate to raise the baffle 11. The lifting motor 4 is a variable frequency speed regulating AC motor, and the end of the motor is equipped with an absolute encoder to control the lifting stroke and slow start and stop of the lifting frame. One of the screw elevators 7 is equipped with a group of proximity switches that control the extreme position of the lifting frame to reset the absolute encoder. The hydraulic cylinder 9 has a built-in displacement sensor to control the rotation angle of the lifting baffle 11. The lifting stroke of the lifting frame and the lifting angle of the baffle are determined according to the specifications of the incoming titanium plate.

[0059] When the door of the heat treatment furnace is opened, the titanium plate rushes out of the door quickly under the drive of the variable frequency motor of the acceleration roller 25, rushes into the quenching tank 1 by its own gravity and initial velocity, and falls on the bottom of the lifting frame. The bottom and both sides of the lifting frame are equipped with a protective plate 12 and an anti-collision plate 13 to prevent the titanium plate from rushing out of the lifting frame or getting stuck in the middle of the flower roller. Six copper slide rails 14 are installed on the baffle to prevent the titanium plate from being scratched.

[0060] The top of the fixed frame 2 of the quenching device is provided with a cold metal detector 15 and a hot metal detector 15, respectively located at the front end and the rear end of the quenching device. When the hot metal detector 15 located at the front end of the fixed frame 2 detects the incoming signal of the titanium plate, it sends a signal after a delay, and the electromagnetic reversing valve of the hydraulic system changes direction, drives the oil cylinder to retract the baffle, and drives the lifting motor 4 in the reverse direction, and the lifting frame returns to the high position. The delay time is approximately equal to the retention time of the titanium plate in the water, and the retention time is determined according to the different specifications and materials of the titanium plate.

[0061] In order to ensure that the horizontal elevation of the roller surface is consistent with the front and rear acceleration rollers when the lifting frame runs to the high position, in addition to the lifting motor 4 adopting frequency conversion control and installing an absolute encoder, the device is also provided with a locking mechanism, which consists of a suspension beam 16, an inclined slider 17, a pressure head 18 and a buffer support 19. The suspension beam and the inclined slider are installed on the fixed frame 2, and the pressure head and the buffer support move together with the lifting frame. When the lifting frame 8 approaches the roller elevation surface, the inclined slider slides 45° under the push of the pressure head and contacts the buffer support. A buffer rubber plate is provided on the buffer support. By adjusting the distance between the buffer support and the inclined slider, the horizontal elevation of the lifting frame at the high position can be controlled, and the impact load of the equipment can be reduced at the same time.

[0062] When the lifting frame moves to the high position (such as Figure 3 As shown in the figure, the transmission motor 20 starts to send the quenched steel plate out of the device of the present invention. The transmission motor is frequency-controlled, and drives the six flower rollers to move synchronously through chain transmission, and controls the chain tightness through the tensioner 21. The flower roller 22 is a stainless steel hollow structure, and the bearing is a graphite self-lubricating bearing. When the cold metal detector 23 at the end of the fixed frame 2 detects that the titanium plate is completely sent out, the lifting frame will drop again to perform the next action cycle.

[0063] Figure 3 The working state of the quenching device shown is a high-position working state during thick plate quenching. When quenching, the titanium alloy thick plate needs to pass the device of the present invention to reach the pre-prepared cage on the unloading roller 24, and then be lifted into the water by a special crane in the workshop. In order to control the quenching transfer time, the running speed of the titanium plate needs to be controlled at about 1m / min. In order to prevent the titanium alloy thick plate from impacting the lifting frame due to possible roller elevation misalignment during operation, a rubber anti-collision plate is provided on the locking mechanism buffer support, which can effectively reduce the impact force, and finally transmit the impact force to the column of the fixed frame 2, ensuring the safety of the equipment.

[0064] In summary, the quenching device for solution heat treatment of the present invention drives the lifting frame to operate in high and low working positions through a lifting mechanism composed of a frequency-controlled lifting motor, a bevel gear steering gear and a screw elevator 7 to meet the quenching needs of titanium plates of different specifications of users. The initial velocity of the titanium plate before entering the water is adjusted by a section of accelerating roller, and the baffle mechanism is used to quickly enter the water using its own gravity and initial velocity. When running at a low position, the baffle mechanism driven by the hydraulic cylinder 9 is used to adjust the optimal water entry angle of titanium plates of different specifications; when running at a high position, the roller surface elevation is adjusted by a locking mechanism composed of an inclined slider and a buffer support to reduce the impact load of the equipment; through a centralized chain drive, it is ensured that the transmission motor can control the operation of the entire equipment at a high position; through a full range of protective plates and anti-collision plates, it is ensured that the titanium plate will not deviate and fall into the quenching tank 1 after quickly entering the water, and the quenching transfer time of the entire titanium plate is controlled within 3s.

[0065] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
