Induction quenching machine tool lathe bed cast iron rail (rail heat treatment), offers a variety of guideway surface fire sensors, splashing the heater. Guide rail quenching machine manufacturers all year round to provide technical support, door-to-door technical guidance.
Cast iron bed guide is a very important part in the machine, especially in the machine tool. The machining precision of the machine tool is directly related to the precision of the guide rail. For the precision machine tool produced in small batch, the processing workload of the guide rail accounts for about 40% of the processing workload of the whole machine tool. Moreover, once the rail damage, maintenance is very difficult. The guide rail and bed surface wear treatment is particularly important.
At present, there are about two ways to quench guide rail in China: one is to quench the bed surface with electric spark; the other is to quench the bed surface or guide rail with induction heating equipment. Induction heating equipment is divided into high-frequency induction heating equipment, medium frequency induction heating equipment, and super audio induction heating equipment.
If the high frequency quenching with the electron tube, because the frequency is too high (200KHz), the hardened layer is too shallow, the sharp Angle effect is strong, the hardness is uneven, the grinding allowance is insufficient. If the SCR is used, the frequency is too low. The hardened layer is too deep and the deformation is too large. Increase grinding workload, hardness layer is inconsistent. And the noise is large, the heating and quenching speed is slow, the power consumption is large, the cost is high.
This equipment adopts IGBT as the main characteristic device super audio induction heating power supply as the heating equipment, moderate quenching layer, uniform hardness, energy saving and power saving.
1, ultra-audio lathe guide rail quenching equipment frequency is generally 25-35khz, suitable for hardening layer of 2-4mm, moderate hardening layer. The hardness meets the requirements and the deformation is small.
2 the speed is one third faster than the old SCR if, the volume is two thirds smaller than the old SCR if,
3. The equipment adopts IGBT imported components from Germany, no need of electron tube and SCR, the efficiency can be increased by one third, and the energy consumption can be reduced by one third.
This transformer isolates the suspended voltage and removes the potential safety hazard by not charging the inductor, effectively solving the accident of electric injury caused by the old equipment.
This set of equipment has a comprehensive protection system, such as water temperature, water pressure, overcurrent overpressure.
The quenching process can be completed within 500mm of the bed surface. The quenching speed is 400mm/min
7, ultra-audio lathe guide rail quenching complete equipment quenching hardness can reach 60HRC, when the material is 45 steel. If the material for HT200 hardness can reach HRC45 degrees.
The deformation of lathe guide rail, linear guide rail, grinding machine face and vertical lathe guide rail quenched by super audio quenching equipment is small, only 20-30s
9. Spray water while quenching, high efficiency, time saving.
10 separate installation of the power supply cabinet and quenching transformer, easy to operate and flexible to move.
11. Soft connection structure is used between inductor and quenching transformer, the gap is adjustable, it is convenient and simple to realize quenching and adjusting the bed body according to the floating magnetic field.

Guide rail quenching equipment inductor according to the cross section of the guide rail of different machine tools, strictly made into imitation shape, generally made of 10*10mm square copper tube. The bed surface is scanned and heated by the notch effect of magnetic circuit. There are also evenly distributed water holes on the inductor; After the scanning heating, a line of scanning water is added for quenching. The user only needs to provide the machine tool guide rail section diagram; The inductor and magnetic permeability are made by our company.
Machine tool guide rail account for fire high frequency power supply (zhengzhou super audio guide rail quenching equipment) advantages:
1, long service life of the transistor power supply has no life limit, maintenance costs are very low.
2, protection system complete power supply with frequency, voltage, current and other maximum minimum protection, equipment working process monitoring, water temperature monitoring and nearly 20 kinds of reliable protection functions.
3, easy to operate and debug power supply has the type of operation and monitoring, can eliminate all kinds of wrong operation and wrong action. Users can install and debug by themselves according to the instruction, no need for the presence of the manufacturer's professional staff.
4, the use of safety power without high voltage danger, so that the operation and maintenance more safe.
5, convenient maintenance of all waterways, electrical are connected by connectors, rectifier and inverter with a fully modular structure, all devices are left with enough repair space, and equipped with repair lighting and socket. The cabinet is equipped with power lighting and 2 1KW and 220V power sockets (switch control)
The system adopts pure water cooling device, internal circulation pure water cooling system, and SCM as the control unit of the branch flow control and measurement circuit. That is to say, flow sensors are set at the outlet of each branch to detect and control the cooling water in three layers of flow, pressure and temperature, which greatly improves the operating reliability of the system.
7. The power cabinet adopts dustproof structure. After years of working on the equipment, the cabinet is as clean as new.
Integrated guide rail quenching machine
YFL series machine tool guide rail plane quenching equipment guide rail high frequency quenching equipment features:
1. Power cabinet, transformer cabinet, and inductor walk together. And the workpiece is fixed. 120KW machine tool, lathe, grinder, planer, milling machine, boring machine, guide rail surface quenching equipment main movement for longitudinal movement; The drive structure is composed of rack and gear. The guide rail is made of 38kg railway rail by grinding. The equipment is divided into an all-in-one machine (heating power + mechanical 3d motion mechanism) and a single high-frequency super audio induction quenching power supply (the user shall be equipped with the guide rail movement of the user's bed or the sliding tooling for the device movement). For details, please contact the seedling manager at 15838311591 for consultation. Special equipment for guide rail bed surface quenching to adapt to the height of different bed, has the function of rising and falling, by the variable speed motor drag screw and nut execution. Speed is divided into fast, slow two gear. The slow gear is mainly used to adjust the sensor in the direction of altitude and the gap between the bed. In order to adapt to the width of different bed, and to make the sensor in the direction of the width of the workpiece, the equipment has the function of lateral movement. With two speed speed regulation. Drive the lead screw and nut by the speed regulating motor. The motor is divided into fast, slow two speed regulation, facilitate the workpiece alignment.
The machine tool guide rail quenching machine adopts igbt, the international advanced device, not the old thyristor, the efficiency is higher than the old thyristor medium frequency 30%-40%, the energy saving 30%-40%.
Four, mature technology, professional level, rich experience, dozens of domestic machine tool factory in use.
