Description

Technical Field

[0001] The utility model belongs to the technical field of heat treatment and relates to a heat treatment device, in particular to a heat treatment device for improving the hardness of high-speed steel. Background Art

[0002] Heat treatment refers to a metal thermal processing technology in which materials are heated, kept warm and cooled in solid state to obtain the expected structure and performance. In the process from the Stone Age to the Bronze Age and the Iron Age, the role of heat treatment has gradually been recognized by people. As early as 770 to 222 BC, the Chinese discovered in production practice that the properties of steel will change due to the influence of temperature and pressure deformation. High-speed steel is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or high-speed steel, commonly known as white steel.

[0003] However, the existing high-speed steel heat treatment equipment has the disadvantage that the high-speed steel is heated unevenly during the heat treatment process, which leads to a long heat treatment time and poor heat treatment effect. Therefore, we propose a heat treatment device for improving the hardness of high-speed steel. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and to propose a heat treatment device for improving the hardness of high-speed steel. The technical problem to be solved by the utility model is: how to achieve uniform heating of high-speed steel and improve the heat treatment efficiency.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A heat treatment device for improving the hardness of high-speed steel comprises a machine platform and a processing frame fixed on the machine platform, a conveying plate is slidably connected to the machine platform, a driving component for driving the conveying plate to move is arranged in the machine platform, clamping and turning components are slidably arranged on the inner walls of both sides of the processing frame, a regulating component for controlling the upward and downward movement of the clamping and turning components is fixed in the processing frame, a lance is fixed on the inner wall of the processing frame, and an air inlet is opened on the processing frame.

[0007] The working principle of the utility model is that the conveying plate can be controlled by the driving component to convey the high-speed steel to the blaster for heat treatment. When the blaster has heat treated one side of the high-speed steel, the conveying plate can be controlled to convey the high-speed steel to the clamping and turning position. At this time, the clamping and turning component drives the high-speed steel to turn over. After the turning over is completed, the conveying plate can be moved to the blaster to heat treat the other side of the high-speed steel.

[0008] The driving assembly includes a driving motor fixed in the machine platform and a driving lead screw rotatably connected in the machine platform. The output end of the driving motor is fixedly connected to the driving lead screw coaxially, and the bottom of the conveying plate is threadedly connected to the driving lead screw.

[0009] By adopting the above structure, the driving motor can drive the driving screw to rotate, and the driving screw will drive the conveying plate to move after rotating, so as to realize the conveying of high-speed steel, improve the overall process speed of high-speed steel heat treatment, and do not require personnel transportation, thereby improving safety.

[0010] The clamping and flipping assembly includes a flipping frame vertically slidably connected to the inner walls of both sides of the processing frame, and a pair of servo motors fixed in the flipping frame. The output end of the servo motor is fixed with a clamping frame, and a pair of meshing transmission gears are rotatably connected in the clamping frame. Clamping arms are respectively fixed on the two transmission gears. A control motor is fixed in the clamping frame, and the output end of the control motor is fixedly connected to the same axis as one of the transmission gears.

[0011] By adopting the above structure, one of the transmission gears can be driven to rotate by controlling the motor. When one of the transmission gears rotates, it will drive the other transmission gear to rotate in the opposite direction, thereby driving the clamping arm to perform a clamping action to clamp and fix the high-speed steel. At this time, the servo motor is used to drive the clamping frame to flip, thereby further driving the high-speed steel to turn over, uniformly heating the high-speed steel, preventing uneven heating, and improving the heat treatment effect.

[0012] The regulating assembly includes a pair of regulating screws vertically rotatably connected in the processing frame and a pair of regulating motors fixed in the processing frame. The output ends of the regulating motors are coaxially fixedly connected to the regulating screws, and the regulating screws are threadedly connected to the turning frame.

[0013] By adopting the above structure, the regulating motor can be used to drive the regulating screw to rotate, and the regulating screw can further drive the turning frame to move up and down, so that when the high-speed steel is turned over, the height of the high-speed steel can be changed to facilitate the normal operation of the turning action of the high-speed steel, improve the overall turning smoothness, and improve the heat treatment efficiency.

[0014] The opposite ends of the two clamping arms are both provided with anti-slip patterns.

[0015] By adopting the above structure, the clamping and fixing effect of the clamping arm on the high-speed steel can be improved through the anti-slip texture.

[0016] Compared with the prior art, the heat treatment device for improving the hardness of high-speed steel has the following advantages:

[0017] 1. By controlling the motor to drive one of the transmission gears to rotate, when one of the transmission gears rotates, it will drive the other transmission gear to rotate in the opposite direction, thereby driving the clamping arm to clamp and fix the high-speed steel. At this time, the servo motor drives the clamping frame to flip, thereby further driving the high-speed steel to turn over, uniformly heating the high-speed steel, preventing uneven heating, and improving the heat treatment effect.

[0018] 2. The driving motor drives the driving screw to rotate, and the driving screw rotates to drive the conveying plate to move, so as to realize the conveying of high-speed steel, improve the overall process speed of high-speed steel heat treatment, and do not require personnel transportation, thereby improving safety.

[0026] The conveying plate 3 can be controlled by the driving component to convey the high-speed steel to the lance 4 for heat treatment. After the lance 4 has heat treated one side of the high-speed steel, the conveying plate 3 can be controlled to convey the high-speed steel to the clamping and turning position. At this time, the clamping and turning component drives the high-speed steel to turn over. After the turning over is completed, the conveying plate 3 can be moved to the lance 4 to heat treat the other side of the high-speed steel.

[0027] The driving assembly includes a driving motor 6 fixed in the machine 1 and a driving screw 7 rotatably connected in the machine 1 . The output end of the driving motor 6 is coaxially fixedly connected to the driving screw 7 , and the bottom of the conveying plate 3 is threadedly connected to the driving screw 7 .

[0028] By adopting the above structure, the driving motor 6 can drive the driving screw 7 to rotate, and after the driving screw 7 rotates, it will drive the conveying plate 3 to move, thereby realizing the conveying of high-speed steel, improving the overall process speed of high-speed steel heat treatment, and eliminating the need for personnel transportation, thereby improving safety.

[0029] The clamping and flipping assembly includes a flipping frame 8 vertically slidably connected to the inner walls of both sides of the processing frame 2, a pair of servo motors 9 fixed in the flipping frame 8, a clamping frame 10 is fixed to the output end of the servo motor 9, a pair of meshing transmission gears 11 are rotatably connected in the clamping frame 10, clamping arms 12 are respectively fixed on the two transmission gears 11, a control motor 13 is fixed in the clamping frame 10, and the output end of the control motor 13 is fixedly connected to the same axis as one of the transmission gears 11.

[0030] By adopting the above structure, one of the transmission gears 11 can be driven to rotate by controlling the motor 13. When one of the transmission gears 11 rotates, it will drive the other transmission gear 11 to rotate in the opposite direction, thereby driving the clamping arm 12 to perform a clamping action to clamp and fix the high-speed steel. At this time, the servo motor 9 drives the clamping frame 10 to flip, thereby further driving the high-speed steel to turn over, uniformly heating the high-speed steel, preventing uneven heating, and improving the heat treatment effect.

[0031] The regulating assembly includes a pair of regulating screws 14 vertically rotatably connected to the processing frame 2 and a pair of regulating motors 15 fixed in the processing frame 2. The output end of the regulating motor 15 is coaxially fixedly connected to the regulating screw 14, and the regulating screw 14 is threadedly connected to the turning frame 8.

[0032] By adopting the above structure, the regulating motor 15 can drive the regulating screw 14 to rotate, and the regulating screw 14 can further drive the turning frame 8 to move up and down, so that when the high-speed steel is turned over, the height of the high-speed steel is changed to facilitate the normal operation of the turning action of the high-speed steel, improve the overall turning smoothness, and improve the heat treatment efficiency.

[0033] The opposite ends of the two clamping arms 12 are provided with anti-slip patterns.

[0035] The working principle of the utility model is as follows: the high-speed steel is placed on the conveying plate 3, and then the driving motor 6 drives the driving screw 7 to rotate. After the driving screw 7 rotates, the conveying plate 3 will be driven to move, so as to realize the conveying of the high-speed steel, and the high-speed steel is conveyed to the musket 4, and one side of the high-speed steel is heat-treated. When the treatment of one side of the high-speed steel is completed, the conveying plate 3 is controlled to convey the high-speed steel to the clamping wall. At this time, one of the transmission gears 11 is driven to rotate by the control motor 13, and when one of the transmission gears 11 rotates, the other transmission gear 11 will be driven to rotate relative to each other, so as to drive the clamping arm 12 to clamp and fix the high-speed steel. The regulating screw 14 is driven to rotate by the regulating motor 15, and the regulating screw 14 further drives the clamping frame 10 to move upward, raising the distance between the high-speed steel and the ground. At this time, the clamping frame 10 is driven to flip by the servo motor 9, so as to further drive the high-speed steel to turn over. After the flipping is completed, the high-speed steel is placed on the conveying plate 3, and then sent to the musket 4 by the conveying plate 3 for heat treatment on the other side.

[0036] In summary, the conveying plate 3 is controlled by the driving component to convey the high-speed steel to the lance 4 for heat treatment. When the lance 4 has heat treated one side of the high-speed steel, the conveying plate 3 can be controlled to convey the high-speed steel to the clamping and turning over position. At this time, the clamping and turning over component drives the high-speed steel to turn over. After the turning over is completed, the conveying plate 3 can be moved to the lance 4 to heat treat the other side of the high-speed steel.
