Description

Technical Field

[0001] The invention relates to the technical field of motorcycle hubs, and in particular to a motorcycle aluminum alloy hub quenching device. Background Art

[0002] Quenching is a heat treatment process. Quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept at this temperature for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation. The solution treatment or heat treatment process with rapid cooling process of materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass is usually called quenching.

[0003] At present, the heat treatment of aluminum alloy wheel hub blanks generally adopts the pool bath immersion quenching process. When the aluminum alloy wheel hub blanks are heat treated in batches, the temperature of the quenching liquid will continue to rise. Since the working temperature of the quenching liquid has requirements, the water temperature for immersion quenching is generally 25-45°C. If the working temperature of the quenching liquid exceeds 60°C, the work should be stopped and the temperature should be lowered to below 40°C before continuing the quenching. However, stopping the work will affect the heat treatment efficiency of the aluminum alloy wheel hub blank and cannot meet the production needs. Summary of the invention

[0031] The bracket 2 is provided with a control assembly for controlling the left and right movement of the moving plate 4. The control assembly includes two fixed plates 3 fixedly connected to the top of the bracket 2. A screw 10 is rotatably connected between the two fixed plates 3, and a guide rod 29 is fixedly connected. Two connecting sleeves 9 are sleeved on the screw 10 and the guide rod 29. The connecting sleeve 9 is threadedly connected to the screw 10, and the connecting sleeve 9 is slidably connected to the guide rod 29. A driving motor 11 is fixedly installed on the upper end of the bracket 2. The driving motor 11 adopts a servo motor. The servo motor can control the speed, and the position accuracy is very accurate. The voltage signal can be converted into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. The received electrical signal can be converted into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque. The end of the output shaft of the driving motor 11 is fixedly installed with a first transmission wheel 12, and one end of the screw 10 is fixedly installed with a second transmission wheel 14. The first transmission wheel 12 and the second transmission wheel 14 are connected by a transmission belt 13.

[0032] Two quenching chambers 15 are formed inside the housing 1 through a partition 18. Liquid guide plates 16 are fixedly installed between the left and right sides of the partition 18 and the housing 1. The left and right ends of the liquid guide plate 16 are symmetrically arranged inclined plate structures. A solenoid valve 17 is fixedly installed at the discharge port of the liquid guide plate 16. The solenoid valve 17 is an industrial device controlled by electromagnetics. It is an automatic basic component used to control fluids. It belongs to an actuator and is not limited to hydraulics and pneumatics. When power is turned on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when power is turned off, the electromagnetic force disappears, and the spring presses the closing member onto the valve seat, and the valve closes.

[0033] A cooling box 20 is fixedly mounted on the side wall of the housing 1. The cooling box 20 is filled with a coolant. An exhaust hole 26 is provided at the upper end of the cooling box 20. A semiconductor cooling sheet 22 is embedded in the outer side of the cooling box 20. When a current passes through a thermocouple formed by connecting a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends. Heat will be transferred from one end to the other end, thereby generating a temperature difference to form a cold end and a hot end. When direct current passes through a thermocouple formed by connecting two different semiconductor materials in series, heat can be absorbed and released at both ends of the thermocouple. , can achieve the purpose of refrigeration, play a role in cooling and cooling, and ensure that the coolant can be kept at a low temperature. The interior of the cooling box 20 is provided with a cooling component for cooling the quenching liquid. The cooling component includes two spiral tubes 25 fixedly connected to the cooling box 20. Two water pumps 23 are fixedly installed on the outside of the cooling box 20.

The other ends of the two spiral tubes 25 are respectively connected to the two quenching chambers 15 through the discharge pipe 21;

[0034] A fan 19 is fixedly installed on the upper end of the cooling box 20. The gas compression and gas delivery machine is a machine that converts the mechanical energy of rotation into gas pressure energy and kinetic energy and delivers the gas. The main structural components of the fan 19 are the impeller, the casing, the air inlet, the bracket, the motor, the pulley, the coupling, the muffler, the transmission parts (bearings), etc. A hollow tube 27 is fixedly installed inside the cooling box 20. The hollow tube 27 is connected to the fan 19, and a plurality of air outlet holes 28 are evenly distributed on the outside of the hollow tube 27.

[0035] Working principle:

[0036] First, the workpiece is placed on the surface of the material placement plate 6, and then the cylinder 7 is turned on. The telescopic end of the cylinder 7 is extended, so that the fixed frame 5 and the material placement plate 6 are lowered. When the workpiece is lowered below the quenching liquid surface, it stops lowering. After the workpiece is immersed in the quenching chamber 15, the workpiece is raised to above the quenching liquid surface under the action of the cylinder 7, and the entire quenching process is completed;

[0037] When the temperature of the quenching liquid in the quenching chamber 15 on the left side rises and cannot meet the quenching requirement, the drive motor 11 is turned on, and the output shaft of the drive motor 11 rotates to drive the first transmission wheel 12, and the second transmission wheel 14 is driven to rotate synchronously under the action of the transmission belt 13, thereby realizing the rotation of the screw 10, and the rotation of the screw 10 causes the connecting sleeve 9 to move, and the movement of the connecting sleeve 9 drives the moving plate 4 to move right, and the material placing plate 6 is moved to the top of the quenching chamber 15 on the right side, so that the quenching efficiency will not be affected;

[0038] At the same time, the electromagnetic valve 17 on the left is opened to discharge the quenching liquid above the liquid guide plate 16 to the bottom. After the discharge is completed, the electromagnetic valve 17 is closed, and then the water pump 23 is turned on. The water pump 23 injects the quenching liquid into the spiral tube 25 through the delivery pipe 24. After the coolant in the cooling box 20 is cooled and cooled, it is discharged to the top of the liquid guide plate 16 through the discharge pipe 21 for reuse. The quenching chamber 15 on the right is the same.

[0039] During the cooling process of the semiconductor refrigeration sheet 22, the fan 19 is turned on to generate wind force to pass through the hollow tube 27 and finally blow out from the air outlet 28, which can force air into the coolant and stir the coolant to facilitate uniform cooling of the coolant without local cooling.
