Traveling-type quenching machine

　　This production line comprises a box-type heating furnace, a box-type tempering furnace, a quenching tank, a rapid cooling platform for normalizing, loading and unloading platforms, a three-axis联动 quenching machine, and a fully automatic control system for the entire production line. It is equipped with a protective atmosphere supply function. The entire production line adopts centralized control, enabling batch processing of workpieces without the need for material trays. The system automatically retrieves workpieces from the upper platform into the heating furnace, then automatically performs the quenching (normalizing), tempering, and further normalizing processes once the required procedures are completed. On the touch-screen interface, users can program multiple process sequences and record all furnace data—including workpiece numbers, material lot numbers, operator information, temperatures, process durations, alarm records, and process curves. Operators can access and review both current and historical data at any time.

　　The box-type heating furnace (tempering furnace) consists of a furnace body, furnace lining, furnace door, furnace door lifting mechanism, furnace door closing and sealing pressurization device, electric heating (or gas heating) system, forced air circulation system within the furnace, gas supply control system, heating control system, safety guard, and maintenance platform. The equipment will automatically carry out the entire process—from loading workpieces into the furnace, to heating, holding at temperature, and finally unloading—according to the programmed process sequence.

The diagrams also show the operational status of each piece of equipment, its processing steps, basic positional states, temperature setpoints, and real-time temperature values.

2. Process parameters: Includes part name, process number, and various process parameters such as temperature and time.

3. Fault Alarm: Includes displaying current faults and displaying historical faults.

4. Data Recording: By moving the cursor left or right, you can display the data at the cursor’s position and also zoom in and out.

 

　　The three-axis, fork-type X-Y-Z transfer machine, controlled by a PLC, achieves fully automatic lateral movement of the large carriage, longitudinal movement of the material-fork trolley, and vertical lifting and lowering of the material fork. It facilitates the transfer of workpieces between the heating furnace, quenching tank, rapid cooling station, and preparation table. The heating furnace’s workpiece quenching process and all quenching tanks consist of a tank body, a circulating cooling system, an underwater forced-agitation system, a liquid-level detection device, a temperature-measurement device, and a control system. Multiple sets of underwater forced-agitation devices are installed inside the tank (around the sides and at the bottom). The underwater agitators mounted on the tank walls can adjust their agitation speed according to the direction of liquid flow, and their variable-frequency speed control enables precise regulation of fluid flow velocity and volume. The circulating cooling system is used to cool the quenching liquid, ensuring that the quenching liquid maintains a controlled temperature range during the quenching process of the workpieces.
