Abstract
Description
Technical Field
[0001] This utility model relates to medium-frequency quenching equipment, and in particular to an improved fully automatic medium-frequency quenching device. Background Technology
[0002] Existing medium-frequency quenching machines use induction coils to heat and quench workpieces. Since different induction coils are required for different workpieces, if the workpiece is too large or too tall, the quenching induction coil needs to be made specifically for the workpiece, which is a very complicated process. In addition, when there are many types of products, different induction coils need to be made, and changing the induction coil is time-consuming and labor-intensive. Furthermore, manual operation is very inefficient, and temperature control relies entirely on the operator's experience, which can easily lead to uneven heating of the workpiece during quenching, resulting in uneven hardness and affecting product quality. Utility Model Content
[0003] To address the aforementioned issues, this utility model provides an improved fully automatic medium-frequency quenching device. This device can flexibly switch heating data and operating speed parameters according to the hardness requirements of different products, effectively controlling the quenching requirements, thereby reducing labor intensity, improving work efficiency, and ensuring product quality.
[0004] The purpose of this utility model is achieved as follows: An improved fully automatic medium-frequency quenching device includes a human-machine interface, an infrared thermometer, and a medium spray pipe. An infrared thermometer is installed on one side of the human-machine interface, and a base is fixed to its outer side. A lifting push rod is installed on the base, and a worktable is installed at the top of the lifting push rod. Rollers are installed side-by-side on the worktable, and a motor is installed on one side of each roller. A medium-frequency quenching machine is located below the human-machine interface, and a medium spray pipe is installed on its outer side. A solenoid valve switch is installed on the medium spray pipe, and the outlet of the medium spray pipe is opposite to the outer periphery of the workpiece. A sensor is located below the outlet of the medium spray pipe. The infrared thermometer is aligned with the point where the outlet of the medium spray pipe is opposite to the workpiece.
[0005] Furthermore, the distance between the nozzle of the media spray pipe and the outer surface of the workpiece is 30~50mm. Furthermore, the workbench is a rectangular frame with roller shaft adjustment grooves symmetrically arranged on both sides of the frame.
[0006] Furthermore, the adjacent rollers on the worktable are all parallel and side by side.
[0007] This invention features a wide operating range, simple operation, high quenching quality, high quenching efficiency, and low labor intensity. Compared with the traditional method of making different quenching induction coils for workpieces of different diameters, this invention can achieve workpiece rotation, enabling the quenching of workpieces of various sizes and diameters with a single induction coil. It effectively solves problems such as the need to make numerous induction coils, uneven heating, difficulty in quality control, high labor intensity, and low quenching efficiency. It achieves automated surface quenching of parts, precise temperature control, and uniform heating, eliminating the need for frequent replacement of induction coils based on part size.

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments. See also Figures 1 to 2 An improved fully automatic medium-frequency quenching device includes a human-machine interface 1, an infrared thermometer 2, a base 5, a lifting push rod 6, a worktable 4, rollers 3, and a medium spray pipe 8. The infrared thermometer 2 is installed on one side of the human-machine interface 1, and the base 5 is fixed to its outer side. The lifting push rod 6 is installed on the base 5, and the worktable 4 is installed at the top of the lifting push rod 6. Adjacent rollers 3 on the worktable 4 are arranged parallel to each other. A motor 7 is installed on one side of each roller 3. A medium-frequency quenching machine 12 is located below the human-machine interface 1. A medium spray pipe 8 is installed on the outer side of the medium-frequency quenching machine 12, and a solenoid valve switch 9 is installed on the medium spray pipe 8. The opening of the medium spray pipe 8 is opposite to the outer periphery of the workpiece 10. A sensor (induction heater) 11 is located below the opening of the medium spray pipe 8. The infrared thermometer 2 is aligned with the opening of the medium spray pipe 8 opposite to the workpiece 10. The medium-frequency quenching machine 12 is model WPS-200KW. The distance between the nozzle of the media spray pipe 8 and the outer surface of the workpiece 10 is 30~50mm. The worktable 4 is a rectangular frame with roller 3 axis adjustment grooves symmetrically arranged on both sides of the frame.
[0011] During operation, place workpiece 10 on the workbench 4, activate the lifting push rod 6 to adjust the center height, bring it close to sensor 11, align the infrared thermometer (NS50P) 2 with the heating area, and press the start button on the human-machine interface (PI8000ig) 1. Sensor 11 will begin heating, and simultaneously, motor (WD80M-07530S) 7 will drive roller 3 to rotate, with workpiece 10 rotating synchronously with roller 3. The infrared thermometer 2 will provide real-time feedback on the heating temperature. When the temperature of workpiece 10 reaches the set value, the control system will send a signal to the solenoid valve switch (JGW040-08 DC24V) 9 to open, and the quenching medium will be evenly sprayed onto the surface of workpiece 10 through the medium spray pipe for quenching. The operation continues until the entire workpiece 10 is quenched, at which point the operation will stop.
[0012] This invention utilizes a human-machine interface 1 for automated operation, allowing for pre-setting of relevant parameters and real-time temperature data feedback for standardized operation. All mechanisms are controlled by the human-machine interface 1 and PLC (Programmable Logic Controller PI8000ig) within the control mechanism, offering both manual and automatic modes for convenient debugging during product changes. Height is automatically adjusted via the lifting push rod 6, offering simplicity and speed. It can flexibly switch heating data and operating speed parameters to meet different product hardness requirements, enabling operators to easily achieve quenching requirements on-site. The fully automated operation significantly reduces labor intensity and increases work efficiency by 30%. Various workpieces do not require dedicated sensors 11; the device achieves full-surface heating, greatly reducing pre-operation auxiliary time.
