模具自动化预热系统，集成到锻造产线的实施方案｜Automated Die Preheating on the Forging Line

摘要：模具低温直接锻打，热冲击大，容易开裂失效。介绍模具自动化预热设备、自动测温，和产线联动控制方案。
Abstract: Forging on a cold die causes severe thermal shock and cracking. This article covers automated preheating equipment, temperature monitoring and line-interlocked control.

正文： 模具如果没有充分预热，高温坯料接触冷模具，巨大热冲击会造成模具表面裂纹，大幅降低模具寿命。传统是人工喷枪烘烤，温度凭经验判断，预热温度不稳定。

自动化预热方案
Automated preheating

采用燃气加热装置或者电加热模块，搭配红外测温，机械手配合，实现模具自动预热。模式 1：锻机内部原位自动预热机构，机构伸入锻模位置自动加热，测温实时反馈，达到设定温度自动停止加热。模式 2：离线预热炉，模具在离线炉内加热，自动换模后直接上机，适合有多套模具频繁切换场景。
Gas heaters or electric modules with IR pyrometers and robot support preheat dies automatically. Mode 1: in-press preheating – the device extends into the die position, heats with live temperature feedback and stops at setpoint. Mode 2: an offline preheat oven for shops that swap dies frequently – dies come out ready to mount.

自动化控制逻辑
Control logic

实时读取模具温度；低于设定温度自动启动加热；达到目标温度停止；超温报警。数据记录模具预热温度，方便审厂查阅。
Read die temperature continuously; start heating below setpoint, stop at target, alarm on overshoot. Preheat records are logged for customer audits.

注意事项
Cautions

现场高温粉尘环境，加热元件、测温探头做好防护；做好燃气场合安全防爆。
Protect heating elements and probes from heat and dust, and follow explosion-safety rules for gas systems.

Summary

模具自动化预热把“凭经验烘烤”变成可量化、可记录的工序，延长模具使用寿命，适合自动化锻造产线配套。
Automated preheating turns guesswork into a measurable, recorded process – longer die life for automated forging lines.
