Description

Technical Field

[0001] The invention relates to the field of blade production, and in particular to a continuous quenching device for blade production. Background Art

[0002] The steel strip quenching process in blade production is one of the key steps to ensure that the blade has high hardness, wear resistance and toughness; the quenching process involves high-temperature heating and rapid cooling of the steel strip to change its microstructure, thereby improving the performance of the material.

[0003] When heating the steel strip, in order to ensure that the steel strip is subjected to more uniform heat radiation and heat conduction during the heating process, a furnace core tube will be set in the heater and the steel strip will be passed through the furnace core tube for heating, thereby reducing the impact of the external environment on the heating process during the heating process, so that all parts of the entire steel strip can reach the same temperature; at the same time, the steel strip is prevented from contacting with the outside air during heating, which may cause oxidation of the steel strip surface and affect the quality of the steel strip; but the furnace core tube will undergo physical changes in a high temperature environment, causing the furnace core tube to deform in the high temperature furnace, causing the steel strip in the furnace core tube to not be in a straight line, affecting the quality of the steel strip.

[0004] In addition, the existing equipment needs to pull the steel strip out from the coiled state in the production method, and then carry out subsequent processing. After the steel strip is pulled out from the bent state, a restoring force will be generated, causing the steel strip to bend. The existing equipment does not tighten the steel strip when sending the steel strip into the high-temperature furnace for heating, causing the steel strip to soften and bend after heating. Summary of the invention

[0005] In order to overcome the disadvantage that the furnace core tube will undergo physical changes in a high temperature environment, causing the furnace core tube to deform in the high temperature furnace, resulting in the steel strip in the furnace core tube not being in a straight line, thus affecting the quality of the steel strip, the present invention provides a continuous quenching device for blade production.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Example 1

[0021] A continuous quenching device for blade production, such as Figure 1-Figure 6As shown, it includes a fixed frame 1, a feeder 2, a discharger 3 and a heater 4; the feeder 2 is fixedly connected to the left side of the fixed frame 1; the discharger 3 is fixedly connected to the right side of the fixed frame 1; and four heaters 4 are fixedly connected to the fixed frame 1; It also includes a furnace core tube 5, a first sliding block 101, a linear optical axis 102 and a moving component; each heater 4 is fixedly connected with a furnace core tube 5 for evenly conducting heat to improve the quenching effect of the steel strip 555; a moving component is connected to the fixed frame 1; eight linear optical axes 102 are fixedly connected to the right side of the fixed frame 1; every two corresponding linear optical axes 102 are slidably connected to the first sliding block 101 together; the first sliding block 101 is connected to the corresponding furnace core tube 5; each first sliding block 101 is connected to the moving component.

[0022] The moving component also includes a motor 104, a rope reel 105 and a pull rope 107; the motor 104 is fixedly connected to the right side of the fixed frame 1; the output end of the motor 104 is fixedly connected to the rotating shaft; eight rope reels 105 are fixedly connected to the rotating shaft; each rope reel 105 has a pull rope 107 wound on it, and the pull rope 107 is a steel wire rope with high strength and high load-bearing capacity and a long service life; every two corresponding pull ropes 107 are connected to the corresponding first sliding block 101.

[0023] It also includes a tension wheel 106 ; eight tension wheels 106 are fixedly connected to the fixing frame 1 ; and each pull rope 107 passes through a corresponding tension wheel 106 .

[0024] It also includes a clamp 10101; the left end of each furnace core tube 5 is detachably connected to the heater 4; each first sliding block 101 is provided with a clamp 10101, and the right end of the furnace core tube 5 is connected to the first sliding block 101 through the clamp 10101.

[0025] The linear optical axis 102 is a chrome-plated optical axis, which has good high temperature resistance and corrosion resistance and a long service life.

[0026] The working principle of the above embodiment is as follows: First, Figure 1 is the viewing angle reference, wherein the side where the fixing frame 1 is marked is the front side; it should be noted that during the production process, the steel strip 555 is continuously conveyed, and the steel strip 555 is transported from left to right by the feeder 2 and the discharger 3, during which the steel strip 555 passes through the heater 4 and the furnace core tube 5; when the steel strip 555 enters the heater 4 and the furnace core tube 5, the steel strip 555 is heated by the heater 4 and the furnace core tube 5; during the heating process, the furnace core tube 5 can provide a relatively closed space, reducing the chance of the steel strip 555 contacting with the outside air, thereby reducing the risk of scale formation; in addition, it can also prevent impurities in the furnace (such as dust, fly ash) from adhering to the surface of the steel strip 555, thereby ensuring its surface quality.

[0027] However, the furnace core tube 5 provides a relatively closed space for the steel strip 555, reducing the chance of the steel strip 555 contacting the outside air, thereby reducing the risk of scale formation: the furnace core tube 5 will undergo physical changes in a high temperature environment, causing the furnace core tube 5 to deform in the high temperature furnace, causing the steel strip 555 in the furnace core tube 5 to not be in a straight line, affecting the quality of the steel strip 555; therefore, Figure 1 and Figure 2 As shown; based on the view from the front to the back, the motor 104 drives the rope reel 105 to rotate clockwise, thereby tightening the pull rope 107 to the right, thereby driving the limit block 103 to move rightward on the linear optical axis 102. Therefore, if the furnace core tube 5 is deformed in the heater 4, the pull rope 107 will push the first sliding block 101 to the right, and then the first sliding block 101 will move rightward on the linear optical axis 102, thereby pulling the furnace core tube 5 to the right; thereby guiding the deformation of the furnace core tube 5, The furnace core tube 5 is kept in a straight line to prevent the furnace core tube 5 from being deformed in the high-temperature furnace, resulting in the steel strip 555 in the furnace core tube 5 not being in a straight line, thus affecting the quality of the steel strip 555; and the left end of the furnace core tube 5 is detachably connected to the heater 4, and the right end of the furnace core tube 5 is fixedly connected to the first sliding block 101 through the clamp 10101. Therefore, when the furnace core tube 5 is damaged, the worker can loosen the clamp 10101 and then quickly remove the furnace core tube 5 for replacement, thereby preventing the damage of the furnace core tube 5 from causing too great an impact on the production of the blade.

[0028] On the basis of the above technical effects, the present invention also has the following advantages: The tensioning force of the pull rope 107 is increased by the tensioning wheel 106, thereby ensuring that the pull rope 107 can be smoothly gathered and unwound; The linear optical axis 102 is a chrome-plated optical axis, which has good high temperature resistance and corrosion resistance and a long service life; The pull rope 107 is a steel wire rope with high strength and high load-bearing capacity and a long service life. Example 2

[0029] On the basis of Example 1, Figure 3-Figure 6As shown, it also includes a limiting block 103, a spring 108, a fixed block 109, a preheating tube 201, a second sliding block 204 and an impurity removal component; each heater 4 is connected to a preheating tube 201 on the left side; a second sliding block 204 is slidably connected inside the preheating tube 201; each second sliding block 204 is fixedly connected to two elastic membranes 20401, and the elastic membranes 20401 are made of silicone rubber; a fixed block 109 is fixedly connected to the lower side of each second sliding block 204; each pull rope 107 passes through the corresponding first sliding block 101 and is fixedly connected to the corresponding fixed block 109; and each pull rope 107 is fixedly connected to a limiting block 103; a spring 108 is fixedly connected between each fixed block 109 and the fixed frame 1, and in the initial state, the spring 108 is in a contracted state, at which time the second sliding block 204 is located on the right side of the corresponding preheating tube 201; each limiting block 103 is located on the left side of the corresponding first sliding block 101.

[0030] The impurity removal component includes a wiping ring 205 and a collecting box 206; a wiping ring 205 is fixedly connected to the middle of each second sliding block 204; a collecting box 206 is connected to the lower left side of each preheating tube 201, and the collecting box 206 is detachably connected to the preheating tube 201; a cleaning port is opened at the lower left side of each preheating tube 201.

[0031] The wiper ring 205 and the steel belt 555 are interference fit.

[0032] The wiper ring 205 is made of tungsten carbide, which has extremely high hardness and melting point and has good wear resistance and heat resistance.

[0033] A connecting pipe 203 is also included; the preheating pipe 201 and the heater 4 are connected by the connecting pipe 203 .

[0034] The working principle of the above embodiment is as follows: The existing equipment needs to pull the steel strip 555 out of the winding state in the production method, and then carry out subsequent processing. After the steel strip 555 is pulled out from the bent state, a restoring force will be generated, causing the steel strip 555 to bend. The existing equipment does not tighten the steel strip 555 when sending the steel strip 555 into the high-temperature furnace for heating, causing the steel strip 555 to soften and bend after heating; and after the steel strip 555 is stored for too long, rust will form on the surface, and a large amount of dust will adhere to it. Figure 4-Figure 6 As shown: in the initial state, the spring 108 is squeezed into a contracted state by the fixed block 109, and the second sliding block 204 is located on the right side of the corresponding preheating tube 201; each limit block 103 is located on the left side of the corresponding first sliding block 101; When the steel strip 555 in the heater 4 is heated, the quenched steel strip 555 is transported from left to right through the discharger 3; at this time, based on the view from the front to the back, the motor 104 drives the rope reel 105 to rotate counterclockwise, thereby unwinding the pull rope 107, and the fixed block 109 contacts the spring 108, and the spring 108 stretches to drive the pull rope 107, the fixed block 109 and the second sliding block 204 to move to the right. In this process, the rust and dust impurities on the surface of the steel material that has not been quenched in the preheating tube 201 are scraped off by the wiping block made of tungsten carbide, and the left side of the second sliding block 204 is inclined from the upper right to the lower left, so the scraped impurities will fall downward along the inclined surface of the left side of the second sliding block 204; When the spring 108 is fully reset, the second sliding block 204 also moves to the right side of the cleaning port, and then brings the scraped rust impurities into the collection box 206; and the wiping ring 205 and the steel belt 555 are interference fit, so when the rust impurities on the surface of the steel belt 555 are cleaned by the wiping ring 205, the wiping ring 205 will also drive the steel belt 555 to move to the left, and at this time, the steel belt 555 is pulled by the discharger 3 to move to the right as a whole, and then the quenched steel belt 555 is pulled by this method to straighten the steel belt 555 to prevent the steel belt 555 from bending when discharging after smelting; When the quenched steel strip 555 is pulled out of the heater 4, the steel strip 555 is conveyed to the right by the feeder 2. At this time, based on the view from the front to the back, the motor 104 drives the rope reel 105 to rotate clockwise, thereby tightening the pull rope 107, thereby driving the pull rope 107, the fixed block 109 and the second sliding block 204 to move to the right; at this time, the spring 108 is squeezed and contracted by the fixed block 109, and when the second sliding block 204 reaches the rightmost side of the preheating tube 201, the spring 108 is contracted to the extreme. , the limit block 103 is fitted with the left side of the first sliding block 101, and the steel strip 555 also enters the heater 4, and then the heater 4 heats and quenches the steel strip 555; at the same time, the motor 104 continues to rotate clockwise, so that the pull rope 107 continues to be tightened, and then the first sliding block 101 and the furnace core tube 5 are squeezed to the right through the limit block 103, so that the furnace core tube 5 remains in a straight line, avoiding deformation of the furnace core tube 5 in the high-temperature furnace, resulting in the steel strip 555 in the furnace core tube 5 not being in a straight line; Furthermore, when the second sliding block 204 moves to the right in the preheating tube 201 , the second sliding block 204 will squeeze the hot air in the heater 4 into the preheating tube 201 , thereby increasing the temperature in the preheating tube 201 to preheat the steel strip 555 .
