SINOCHEM International Tendering Co., Ltd., entrusted by the Buyer, hereby carries out invitation bid for the supply of the following goods and related services, and now invites eligible bidders to attend the bidding.
1. Name, quantity and some technical parameters of the bidding products:
Package 1: Automatic Welder for Aluminum Alloy Components 1 set
7. Application of the Equipment
KK end robot is mainly for welding surface welds on the jobs. The pairing of job and welding are carried out separately. First of all, job pairing, tack welding, internal rib weld, etc., which are difficult for the robot to complete, shall be done on the pairing tooling manually. Then the job is dismounted from the pairing tooling, and re-clamped on the robot tooling, and clamped on the robot clamp.
*9. Configurations and Performance of the Equipment
*9.1 Lateral Gantry
The lateral gantry is fixed on the ground, on which, one MIG welding robot and one tool robot shall be suspended concurrently. The welding robot shall be movable along gantry X/Y axis through the external cross slide; the tool robot shall need no external axis, and move directly along the gantry. The two robots shall be able to fulfill welding and before/after welding treatment of KK ends in a programmed way. The gantry height shall be designed acc. to the tooling position, and the final sizes of which shall be subject to confirmation from the Buyer.
*9.2 Welding Robot
The welding robot shall be a standard 6-axis robot, which shall work with the positioner, be furnished with a laser weld tracking system, and a touch sensor, and be driven by an AC servomotor. The welding protective gas cylinder shall be placed fixedly on the ground, and shall not move with the robot.
*9.3 Welding power supply
The welding power supply shall preferably be Fronius5000. The rated output welding current shall be 500A. The power supply shall be pulse inverter one. The welding torch shall be water cooled. The wire feeder shall guarantee reliable feeding of wire in dia. 1.2mm and 1.6mm, which shall use big barrel of wire. And it shall be easy to replace welding wires.
*9.4 Tool Robot
The tool robot shall be a standard 6-axis robot, which shall comprise a polishing brush, an air gun, a grilling gun, and an infrared temperature measuring device, and allow automatic tool change. The tool robot shall work with a positioner to fulfill polishing, air blowing, pre heating and temperature measuring of multiple courses of welds. The pipelines of each system shall be reasonably designed, and avoid messy lines and pipes on surfaces, the gas cylinders for the air supply and heating shall be placed on the ground. The solution shall be described separately in the Bid.
*9.5 Tooling & Fixture
