Ⅰ. Track Link Hardening and Tempering Line Overview

The production line incorporates dedicated processing positions, a mechanical transport system and coordinated operating controls.

Its horizontal hardening machine uses a dual-workpiece arrangement, while the transport configuration supports dual-channel and batch processing applications.

The exact equipment layout and processing sequence are determined by the workpiece specifications and production requirements.

Ⅱ. Track Link Tread Surface Hardening

Track links have a different geometry from conventional shafts, rods and cylindrical parts. Their connecting holes, irregular cross-sections and defined roller-contact surfaces require dedicated workholding and heating arrangements.

Tread Surface Treatment

The primary treatment area is the track link tread or rail surface.

Induction heating is used to heat the required surface region before quenching. The induction coil and workpiece positioning system are designed around the specified treatment area.

The required heating pattern depends on the material, surface geometry, coil position and operating conditions.

Workpiece Requirements

The equipment configuration takes account of:

•Track link material and initial heat treatment condition

•Link pitch and overall dimensions

•Tread surface geometry and treatment location

•صلابة السطح المطلوبة

•Effective hardened case depth

•Production quantity and workpiece variety

Different track link specifications may require adjustments to the fixture, induction coil and operating program.

Hardening results must be verified against the customer’s material and inspection requirements.

Ⅲ. Induction Heating and Quenching Process

The hardening machine combines controlled workpiece positioning, induction heating and quenching.

تحديد موضع الشغل

The track link is located and supported by dedicated mechanical fixtures.

The documented machine design uses guide-wheel positioning and provides for adjustment of the clearance between the inductor and workpiece.

These features help establish the required relationship between the induction coil and the tread surface during processing.

التسخين بالحث

The induction power supply delivers energy to the ملف الحث, generating an alternating electromagnetic field that heats the selected conductive region of the workpiece.

The heating arrangement is matched to the track link geometry and required hardening area.

Depending on the selected processing program, the machine supports different operating methods, بما في ذلك:

•Fixed-position timed hardening

•Programmed positioning and مسح

•Section-by-section positioning

•Stepwise preheating and quenching

The appropriate operating method depends on the workpiece geometry and heat treatment requirements.

البرودة

بعد التسخين, the specified surface region is quenched under conditions selected for the track link material.

The quenching system is coordinated with the heating sequence and workpiece positioning mechanism.

The documented equipment includes quenching-liquid collection, filtration and supporting cooling-water and pump-control systems.

The required quenching conditions are established according to the target hardness, hardened depth and material properties.

Ⅳ. Tempering and Post-Tempering Cooling

Tempering forms part of the complete track link heat treatment production line.

بعد التبريد, the track link proceeds to the التخطيط الحراري منصة. Tempering is used to adjust the properties of the hardened material according to the required mechanical performance.

The appropriate tempering conditions depend on the material grade and specified heat treatment requirements.

Tempering Section

The production line includes a dedicated tempering operation following the hardening process.

The heating method, temperature and operating sequence of the tempering equipment are established according to the selected line configuration.

Post-Tempering Cooling

بعد هدأ, the workpiece passes through a subsequent cooling stage.

The cooling operation is coordinated with the transport system to support movement through the production sequence.

The arrangement of the hardening, tempering and cooling sections is determined by the required production process and available equipment layout.

Ⅴ. Horizontal Dual-Workpiece Machine and Transfer System

The KECHUANG equipment uses a horizontal, programmable hardening machine with a dual-workpiece processing arrangement.

The mechanical structure supports workpiece positioning, induction heating operations and controlled movement.

Dedicated Workpiece Fixtures

The fixture system accommodates the geometry of crawler track links.

Guide-wheel positioning helps locate the workpiece, while the induction coil clearance can be adjusted according to the selected processing requirements.

Fixtures and guides are configured for the applicable track link dimensions and treatment area.

Mechanical Movement and Support

The documented machine structure includes positioning and supporting mechanisms, a workpiece rotation mechanism, lifting and guiding components, and a counterbalance arrangement.

These components form part of the machine’s mechanical design. Their specific operation and coordination depend on the selected equipment configuration.

Dual-Channel Workpiece Transfer

A conveyor system moves workpieces through the production arrangement.

The equipment is designed to support dual-channel operation and batch treatment of crawler track links.

The dual-workpiece machine arrangement and dual-channel transfer arrangement describe different aspects of the equipment. They do not necessarily mean that two workpieces are heated simultaneously.

Adaptation to Different Track Link Pitches

The equipment is intended to accommodate track links with different pitches.

The applicable size range, adjustment method and fixture configuration are established according to the customer’s workpiece drawings.

Ⅵ. CNC/PLC Control and Auxiliary Systems

The track link hardening line integrates electrical control, mechanical movement and induction power regulation.

Programmable Process Control

The equipment can use a CNC or PLC-based control system together with variable-frequency speed control.

The control arrangement supports workpiece positioning and scanning operations, while communication between the PLC and induction power supply coordinates the heating sequence.

For CNC-equipped configurations, processing programs can be prepared and stored for different workpiece requirements.

This allows the machine to operate according to the selected track link specification without requiring continuous manual adjustment during the programmed hardening cycle.

Electrical Equipment Arrangement

The documented machine design places the control cabinet and transformer cabinet separately.

This arrangement provides access to the relevant electrical equipment and supports adjustment and maintenance.

The machine also includes a mounting and adjustment arrangement for the hardening transformer.

Supporting Machine Systems

The published equipment configuration includes:

•Quenching-liquid collection system

•Quenching-liquid filtration system

•Cooling-water circuit and pump-control system

•Door-control system

•Workpiece transport control

•Lifting and guiding mechanism

•Counterbalance mechanism

•Water-mist collection system

The production line documentation also identifies an energy and quality-control analysis system.

The specific measurements, analysis functions and available interfaces of this system should be defined in the equipment specification for the selected project.

Ⅶ. Machine Configuration and Technical Requirements

The complete line combines the main hardening machine with the tempering, التبريد, transfer and auxiliary equipment required for the selected production process.
