Technical Field
[0001] This invention relates to the field of valve manufacturing and processing technology, specifically to a six-station valve cone surface welding post-weld flame heating device. Background Technology
[0002] Valve is a key component of the engine. After the conical surface is welded, it needs to be heated to ensure the structural stability and performance of the welded part.
[0003] In existing technologies, heating equipment for valve cone welding is mostly a single-station structure, which has the following drawbacks: First, the heating efficiency is low, and the processing time for a single part is long, which cannot meet the needs of mass production; second, the heating uniformity is poor, and the lack of coordinated design of rotation and revolution leads to uneven heating of the valve, affecting product quality; third, there is a lack of targeted cooling and heat insulation structures, and the parts are prone to burning due to high temperature during the heating process, affecting product performance; fourth, the degree of automation is insufficient, and both loading and unloading require manual operation, which not only increases labor intensity but also easily leads to product quality problems due to human operation errors.
[0004] Therefore, there is an urgent need for a flame heating device that is highly integrated and automated, has good heating uniformity, and is equipped with protective functions, in order to solve the above-mentioned problems existing in the current technology. Summary of the Invention

[0021] As attached Figure 4 As shown, the rotary station 1 includes a rotary disk 11, with six valve supports 14 fixedly mounted on top of the rotary disk 11. The rotary disk 11 is connected to a differential 13 via a rotating shaft at its lower end. The other end of the differential 13 is connected to the output shaft of a rotary motor 12. The rotary motor 12 drives the rotary disk 11 to rotate, with each rotation angle being the included angle between two adjacent valve supports 14, thus achieving the switching of valve heating treatment. The rotary disk 11 and the valve supports 14 are connected by bearings, allowing the valve supports 14 to rotate on the rotary disk 11. A driven pulley 15 is connected below the valve supports 14, and a driving pulley 16 is mounted above the electromechanical system control cabinet 5. The driving pulley 16 and the driven pulley 15 are connected by a belt, and the driving pulley 16 is connected to the output shaft of the motor, thus ensuring that the valve supports 14 are heated all around the valve. Through the above structure, the rotation and revolution of the valve supports 14 are linked, improving heating uniformity and enhancing the quality of valve production.
[0022] A cooling tank 3 is installed above the rotating disk 11, and the cooling tank 3 is located between the six valve supports 14. The cooling tank 3 is made of high-temperature resistant alloy steel and has an internal circulating cooling water channel, with the cooling water flow rate controlled at Q=0.5. 1.2L / min ensures that the valve cools down quickly and evenly after heating, avoiding structural deformation caused by local overheating.
[0023] As attached Figure 3 As shown, heating station 2 includes a support 22 and a flame gun 21. The flame gun 21 is fixed on the support 22, and the nozzle angle of the flame gun 21 can be adjusted. The base of the flame gun 21 is connected to a gas pipe; the angle adjustment range of the flame gun 21 is θ=15°. 45 When processing valves of different models, precise alignment of the heating position is achieved by adjusting the flame gun angle by 21 degrees. Propane or acetylene is used as the fuel gas, and the combustion temperature is controlled at T=2800. 3200K to ensure adequate heat treatment of the valve welding area.
[0024] As attached Figure 5As shown, the unloading system 4 includes a column 41, which is fixed to the electromechanical system control cabinet 5 at its bottom. A slide rail is provided on the side of the column 41, and a longitudinal slide block 42 is slidably connected to the slide rail. A cylinder 43 is mounted on the longitudinal slide block 42. When processing different types of valves, the heating position is precisely aligned by adjusting the longitudinal height of the cylinder 43. A valve manipulator 44 is mounted on the output shaft of the cylinder 43. The cylinder 43 is connected to the air source system via a cylinder triplet 52. An unloading slide 45 is provided on the front of the column 41. The unloading slide 45 can be adjusted in tilt angle and is located below the valve manipulator 44. The stroke of the cylinder 43 is controlled at S=150. 300mm, robotic gripping force controlled at F=50 100N ensures stable valve clamping without damaging the surface.
[0025] A power switch 51 is installed on the back of the electromechanical system control cabinet 5. The power switch 51 can control the power supply or de-energization of the rotary motor 12, the motor of the drive pulley 16, the air supply system of the cylinder 43, and the flame gun 21. A photoelectric sensor is installed above the cylinder 43. A PLC controller is installed inside the electromechanical system control cabinet 5. The photoelectric sensor is electrically connected to the PLC controller.
[0026] The equipment also includes a control switch 6, which is mounted on a column 41 on one side and electrically connected to the PLC controller. The control switch 6 has four buttons: run, stop, reset, and emergency stop. The equipment is controlled by the control switch 6. The emergency stop button has a response time of t<50ms to ensure rapid shutdown in case of emergencies and improve equipment safety.
[0027] Working principle: The operator stands behind the equipment, between the two unloading systems 4, turns on the control switch 6, and starts the equipment. The operator manually places the valve to be processed on the valve support 14 in front of them. The photoelectric sensor detects the valve, the rotary motor 12 starts working, and moves the valve to below the flame gun 21. At the same time, the motor of the drive pulley 16 starts working, and the valve support 14 starts to rotate. Meanwhile, the operator places the valves on the valve support 14 one by one.
[0028] After being heated by three flame guns 21, the valve to be processed is taken out by the unloading system 4 and sent to the storage box by the unloading slide 45.
[0029] The entire processing is continuous, and all that is needed is for the operator to place the valve on the valve support 14. The processing status can be observed with the naked eye, and in case of an emergency, the equipment can be stopped by controlling switch 6.
