品名:: 数控环缝焊接机床
Name:: CNC ring seam welding machine
Model: KLTHFH-400A
Function: CO2/MAG/MIG/TIG/Plasma

1,简介   Introduction

1)KLTHFH-400A/B/W/WS 数控环缝焊接机床是一台实现环缝自动焊接设备。可配用TIG弧焊机(填丝或不填丝)、熔化极气体保护焊机(CO2/MAG/MIG)、等离子等焊接电源组成一套环缝自动焊接系统;

1) KLTHFH-400A/B/W/WS CNC ring seam welding machine is a kind of automatic welding equipment for ring seam. It can be equipped with a TIG argon arc welding machine (filled or unfilled), a gas shielded gas welding machine (CO2/MAG/MIG), plasma and other welding power sources to form a ring seam automatic welding system;


2) Consisting of bed body, rotary positioner, moving mechanism, pneumatic tailstock, welding gun pneumatic lifting mechanism, welding gun adjusting device and CNC automatic welding controller;

3) 该产品采用的是组合式结构,搭配和装拆方便,机动性好。因此,配以合适的焊接电源就可以适用于各类环形焊缝的自动焊接;

3) The product adopts a combined structure, which is convenient for assembly and disassembly, and has good maneuverability. Therefore, with the appropriate welding power supply, it can be applied to the automatic welding of all kinds of ring welds;


4) The equipment is mainly used for high quality circumferential seam welding of workpieces of different materials, different sizes and shapes;


4) Similar workpieces such as air reservoirs, fire tubes, drive shafts, shock absorbers, mufflers, pipe flanges, etc. Two welding torches are mounted on the horizontal double-ring seam welder and can be welded at the same time.

3.1步进驱动装置/Stepper drive and motor



YKD2405M/YKD2408M is a high-performance digital stepping driver based on a new generation of 32-bit DSP technology. The driving voltage is DC20-50V/DC20-80V, which is powered by a single power supply. It is a two-phase hybrid stepping motor with various currents of 4.0A or less and outer diameters of 42mm, 57mm and 86mm.

     The driver adopts servo-like control principle internally, unique circuit design and superior software algorithm processing, which can make the motor run smoothly at low speed even under low subdivision conditions, with almost no vibration and noise; smooth and precise current control technology Greatly reduce the motor heating; external 16-speed constant torque subdivision, the highest 200 subdivision; photoelectric isolation differential signal input, strong anti-interference ability; with overvoltage, undervoltage, overcurrent and other error protection; at the point Medium and low speed applications such as glue machine and laser engraving have obvious advantages in stability, vibration and noise.Greatly improve equipment performance.
