Description

Technical Field

[0001] The present invention relates to the field of heat treatment technology, and more specifically, to a heat treatment control system for producing bearing steel balls. Background Art

[0002] In order to ensure that the bearing steel balls have a long service life and reliability during operation, the steel balls must be heat treated. Steel ball heat treatment is a process in which the steel ball workpiece is placed in a certain medium and heated to a suitable temperature, and then kept at this temperature for a certain period of time and then cooled at different speeds. Steel ball heat treatment is one of the important processes in mechanical manufacturing.

[0003] The steel balls currently used are generally high-carbon steel. The blank is first heated to about 1200℃, then forged with an air hammer, and after the temperature drops to between 800-850℃, it is immediately put into water at a temperature of 30-40℃ for quenching. Accurately grasping the optimal quenching temperature range of the steel ball during the cooling and sorting process is the key to preventing the steel ball from breaking and ensuring the quality of the finished steel ball. If the temperature is not strictly controlled and the temperature is too high or too low, it will affect the quality of the finished steel ball. Therefore, it is extremely important to control the optimal quenching temperature of the steel ball.

[0004] Most traditional temperature-waiting sorting devices use an inclined rail self-sliding device for sorting. The inclined rail self-sliding device consists of an inclined rail and a ball pusher. Workers put the forged steel balls on the inclined rail. Under the action of their own weight, the steel balls roll along the inclined track to the heat treatment waiting area. The operator uses an infrared thermometer to measure the temperature of the steel balls in the waiting area. Those with qualified temperature are placed in the front and pushed out by the ball pusher to the heat treatment water pool for quenching. Those with high temperature continue to stay in the waiting area to cool down until the temperature is qualified; those with low temperature are picked out for separate treatment.

[0005] However, due to the cumbersome temperature measurement and low degree of automation, operators sometimes rely on their eyesight to judge the temperature of the steel balls, resulting in large temperature control deviations, unstable heat treatment quality of the steel balls, and even some waste balls, affecting the heat treatment quality of the steel balls. At the same time, for those with qualified temperatures detected, subsequent processing is required, and the process is cumbersome, which reduces the efficiency of steel ball heat treatment.

[0033] For example, see Figure 1-10 , the present invention provides the following technical solutions:

[0034] A heat treatment control system for bearing steel ball production, specifically, comprises a heat treatment table 1; the heat treatment table 1 comprises a quenching box 2; the top of the quenching box 2 is a hollow structure, and a connecting pipe 3 is evenly penetrated and fixed on the top; a sorting assembly 5 is fixed on the connecting pipe 3 by fastening bolts; the sorting assembly 5 comprises a sorting frame 6 fixedly mounted on the connecting pipe 3 and a sliding frame 7 slidably arranged on the sorting frame 6; the sorting frame 6 comprises a vertical pipe 8; a heat exchange pipe 9 is connected and fixed at the top of the vertical pipe 8; a spiral groove 10 is opened on the outer peripheral side of the heat exchange pipe 9; a spiral stopper with a hollow structure inside is fixed on the outer peripheral side of the heat exchange pipe 9 Plate 11; a bearing steel ball 12 is rolledly arranged between the spiral groove 10 and the spiral baffle 11; an arc tube 13 is arranged between both ends of the spiral baffle 11 and the side surface of the heat exchange tube 9; a ball inlet tube 14 and a ball outlet tube 15 are arranged at both ends of the spiral baffle 11 in sequence; an air inlet pipe 16 and a guide pipe 17 are arranged on the side surface of the spiral baffle 11 in sequence from top to bottom; a slide rod 21 is slidably arranged in the guide pipe 17; an air supply pipe 18 is fixed to the end of the guide pipe 17; an L-shaped support plate 19 is fixed to the side surface of the guide pipe 17; an infrared thermometer 20 is installed on the top of the L-shaped support plate 19.

[0035] The working principle of the first embodiment is as follows: the steel ball 12 to be tested is sent in through the ball pipe 14, and the steel ball 12 rolls downward along the spiral groove 10 and the spiral baffle 11. The power of the external blower is controlled to control the air volume of each group of air inlet pipes 16, thereby reducing the speed of the rolling steel ball 12, and while cooling the steel ball 12 with air, the heat exchange time between the steel ball 12 and the heat exchange tube 9 is extended to improve the cooling effect. When the corresponding infrared thermometer 20 detects that the steel ball temperature is in the range of 800-850°C, the steel ball 12 falls into the quenching box 2 through the first unloading pipe 39 for quenching, thereby improving the automation and accuracy of temperature sorting, thereby improving the quality of heat treatment of the steel ball 12.

[0036] For example 2, please refer to Figure 1-10 The second embodiment is improved on the basis of the first embodiment as follows. Specifically, the air inlet pipe 16 and the guide pipe 17 are both arranged to be tilted upward; a fixing ring 22 that is slidably matched with the slide rod 21 is fixed inside the guide pipe 17; a piston 23 that is slidably matched with the guide pipe 17 is fixed at one end of the slide rod 21, and a squeezing ball 24 is fixed at the other end; a return spring 25 that is sleeved on the slide rod 21 is fixed between the piston 23 and the fixing ring 22; a push rod 34 is fixed on the side of the piston 23; and a pressure sensor 4 is fixed on the side of the fixing ring 22.

[0037] The air supply pipe 18 and the air inlet pipe 16 are respectively connected to the corresponding external blower outlets through hoses; a control valve 29 is installed on the inlet pipe 14 near its end; the top of the heat exchange pipe 9 is connected to the infusion pipe 26; the infusion pipe 26 is connected to the external discharge pipe; the top of the quenching box 2 is connected to the inlet pipe 27; the inlet pipe 27 is connected to the external infusion pipe; a controller 28 is installed on the side of the quenching box 2; the input end of the controller 28 is electrically connected to the infrared thermometer 20 and the pressure sensor 4, and its output end is electrically connected to the blower and the control valve 29.

[0038] A U-shaped plate 30 is fixed to the side surface of the ball outlet tube 15; an ear plate 31 is fixed to the bottom surface of the U-shaped plate 30; a first electromagnetic coil 32 and a second electromagnetic coil 33 electrically connected to the output end of the controller 28 are symmetrically fixed to the two opposite sides of the ear plate 31; the sliding frame 7 includes a slide plate 35 slidably arranged in the U-shaped plate 30; an L-shaped support plate 36 is symmetrically fixed to the two opposite sides of the slide plate 35; an armature column 37 is fixed to the side surface of the L-shaped support plate 36; a connecting spring 38 is fixed between the L-shaped support plate 36 and the ear plate 31;

[0039] A first discharge pipe 39 is fixed on the surface of the slide plate 35, and a second discharge pipe 40 and a third discharge pipe 41 are symmetrically fixed on the surface of the first discharge pipe 39 on both sides; a discharge port 42 is provided on the side surface of the first discharge pipe 39 near its end; a plurality of feed ports 43 are evenly provided on the top of the quenching box 2; a material guide pipe 44 is provided on the side surface of the second discharge pipe 40 and the third discharge pipe 41, tilted downward.

[0040] The working principle of the second embodiment of the present invention is as follows: the steel ball 12 rolls down along the spiral groove 10 and the spiral baffle 11. In the initial state, the power of the external blower connected to the air inlet pipe 16 is relatively large, so that the air output of the air inlet pipe 16 is relatively large, so that the steel ball 12 rolling down and approaching the corresponding air inlet pipe 16 slows down to a stop. During this process, the steel ball 12 is cooled by the air, and at the same time, it exchanges heat with the coolant flowing inside the heat exchange tube 9 and the spiral baffle 11, thereby improving the cooling effect of the steel ball 12.

[0041] Air holes are provided on the sides of the air supply pipe 18, and the external blower connected to the air supply pipe 18 is controlled to be started. Most of the airflow pushes the piston 23 to slide along the piston cylinder 17, and part of the airflow is discharged through the air holes. The return spring 25 is compressed, and the piston 23 slides and drives the slide bar 21 and the squeezing ball 24 to slide toward the spiral groove 10 until they are against the spiral groove 10. At this time, the low rod 24 is against the pressure sensor 4, and the pressure sensor 4 transmits a signal to the controller 28. The controller 28 controls the power of the external blower connected to the air inlet pipe 16 to decrease, so that the air outlet of the air inlet pipe 16 is reduced. Under the action of gravity, the steel ball 12 rolls down until it is blocked by the low rod 24, so that the infrared thermometer 20 can measure the temperature of the steel ball 12 in a static state.

[0042] When the corresponding infrared thermometer 20 detects that the temperature of the steel ball 12 is within the range of 800-850°C, the signal is transmitted to the controller 28. The controller 28 controls the external blower connected to the air inlet pipe 16 to stop working. Under the elastic reset force of the reset spring 25, the slide rod 21 and the extrusion ball 24 are reset and stored in the piston cylinder 17, and the restriction on the steel ball 12 is released. The steel ball 12 rolls under the action of gravity and enters the first discharge pipe 39 through the ball outlet pipe 15, continues to roll, and falls into the quenching box 2 through the discharge port 42 and the feed port 43 in turn for quenching.

[0043] When the corresponding infrared thermometer 20 detects that the temperature of the steel ball 12 is lower than 800°C, the controller 28 controls the first electromagnetic coil 32 to be energized, attracting the corresponding armature column 37, and the corresponding connecting spring 38 is compressed, and another set of connecting springs 38 is stretched, so that the second discharge pipe 40 moves to a position coaxial with the ball outlet pipe 15, and the controller 28 controls the external blower connected to the air inlet pipe 16 to stop working. Under the elastic reset force of the reset spring 25, the slide rod 21 and the extrusion ball 24 are driven to reset and be stored in the piston cylinder 17, thereby releasing the restriction on the steel ball 12, and the steel ball 12 rolls through the ball outlet pipe 15 into the second discharge pipe 40.

[0044] When the corresponding infrared thermometer 20 detects that the temperature of the steel ball 12 is higher than 850°C, the controller 28 controls the second electromagnetic coil 32 to be energized, attracting the corresponding armature column 37, and the corresponding connecting spring 38 is compressed, and another set of connecting springs 38 is stretched, so that the third discharge pipe 41 moves to a coaxial position with the ball outlet pipe 15, and the controller 28 controls the external blower connected to the air inlet pipe 16 to stop working. Under the elastic reset force of the reset spring 25, the slide rod 21 and the extrusion ball 24 are driven to reset and be stored in the piston cylinder 17, thereby releasing the restriction on the steel ball 12, and the steel ball 12 rolls into the third discharge pipe 41 through the ball outlet pipe 15.

[0045] For example 3, please refer to Figure 1-10 , the third embodiment makes the following improvements on the basis of the second embodiment. Specifically, a heating tube 45 and a cooling tube 46 are fixed in sequence on the top of the quenching box 2 between two adjacent feeding ports 43; a driving motor 47 is installed on the top of each heating tube 45 and cooling tube 46, and a conveying dragon screw 48 is rotatably arranged inside the heating tube 45; an electric heating wire is installed inside each heating tube 45; a cooling fan is installed on the top of the cooling tube 46; the output end of the controller 28 is electrically connected to the electric heating wire and the cooling fan respectively; a feed pipe 49 is arranged on the side surface of each heating tube 45 and cooling tube 46 near its bottom end, tilted upward; a feed hopper 50 is arranged at the end of the feed pipe 49.

[0046] A discharge pipe 51 is arranged on the side surface of each heating tube 45 and cooling tube 46 near the top thereof, tilted downward; a branch pipe 52 connected to the adjacent heating tube 45 and cooling tube 46 is symmetrically arranged on the side surface of the ball tube 14; a support rod 53 is fixed on the top of the quenching box 2; a conical ball guide platform 54 is fixed on the top of the support rod 53; a retaining ring 55 is fixed on the side surface of the conical ball guide platform 54; and ball outlet grooves 56 connected to each ball tube 14 are evenly arranged on the side surface of the retaining ring 55.

[0047] A C-shaped frame 57 is fixed to the surface of the conical ball guide table 54; a servo motor 58 electrically connected to the output end of the controller 28 is installed on the top of the C-shaped frame 57; a fixed disk 59 is fixed to the output end of the servo motor 58; an L-shaped lever 60 adapted to the side surface of the conical ball guide table 54 is fixed to the side surface of the fixed disk 59; and a goal channel 61 is fixed to the surface of the retaining ring 55.

[0048] Working principle of the third embodiment: when the corresponding infrared thermometer 20 detects that the temperature of the steel ball 12 is higher than 850°C, the steel ball 12 passes through the third discharge pipe 41, the guide pipe 44 and the feed pipe 49 on the cooling cylinder 46 in sequence, enters the cooling cylinder 46, controls the driving motor 47 to drive the conveying dragon winch 48 to lift the steel ball 12, and controls the cooling fan to start to cool the steel ball 12, and discharges it into the corresponding branch pipe 52 through the discharge pipe 51, and re-enters the ball pipe 14 for cyclic temperature detection.

[0049] When the corresponding infrared thermometer 20 detects that the temperature of the steel ball 12 is lower than 800°C, the steel ball 12 passes through the second discharge pipe 40, the guide pipe 44 and the feed pipe 49 on the heating cylinder 45 in sequence, enters the heating cylinder 45, controls the driving motor 47 to drive the conveying dragon winch 48 to lift the steel ball 12, and controls the start of the electric heating wire to heat the steel ball 12, discharges it into the corresponding branch pipe 52 through the discharge pipe 51, and re-enters the ball pipe 14 for cyclic temperature detection.

[0050] The steel ball 12 to be tested is fed into the conical ball guide table 54 through the goal channel 61. When each group of sorting components 5 completes the temperature sorting of a group of steel balls 12, the controller 28 controls the solenoid valve 29 on the corresponding goal tube 14 to open, controls the start servo motor 58 to drive the lever 60 to rotate, and moves the steel ball 12 on the conical ball guide table 54. After the steel ball 12 close to the corresponding goal tube 14 enters the goal tube 14, the corresponding solenoid valve 29 is controlled to close, thereby realizing automatic feeding of the steel balls 12 and improving work efficiency.
