Recently, the digital welding and crawling manipulator developed by 728 Pengli Technology Co., Ltd. successfully passed the test and verification of Dalian Shipbuilding Industry Group and entered the stage of large-scale application.
Pengli Technology utilizes its own research advantages in the field of welding automation equipment, and cooperates with Dalian Shipbuilding Industry Corporation in the technical research of high-efficiency welding equipment. It has set up a technical research team to conduct in-depth research on marine welding technology and welding workpieces. Series of digital welding and crawling robots for fillet welding, hard-track all-position welding, T-BAR special welding, soft-track all-position welding, etc., aim to effectively solve the problem that shipyards rely heavily on manual welding.
In the product development process, Pengli Technology fully utilizes the advantages of electronic technology, optimizes the design of anti-electromagnetic interference integrated circuits, and enables the equipment to work stably under harsh environments. The motion control chip is used to develop a motor motion control system with independent intellectual property rights. It has five different welding gun swinging and walking modes, which can meet single-layer and multi-layer multi-pass welding processes in various weld forms. According to the working characteristics of the shipyard construction area, the concept of low-voltage safe power supply is adopted, and the welding machine on site is adopted. DC 24V direct power supply improves safety and saves costs. At the same time, combined with the operation and maintenance requirements of the shipyard during use, the modular design concept is adopted to make the series of digital welding crawling robots compact, easy to disassemble and maintain, and meet the requirements of on-site industrial implementation.

Plastic Pipe Vacuum Calibration Tank

The Molten Extrudate in The Extruder Is Drawn into The First Vacuum Chamber Through Calibration

The Vacuum Then Forces the Plastic Against the Calibration Tool While Cooling Its Surface Enough to Maintain Proper Dimensions. Cooling Water Enters the Chamber Through the Spray Bar.

The Calibrated Plastic Is Pulled Through a Second Vacuum Tank, Where It Is Cooled by Water Filling the Compartment. A Vacuum Can Be Applied to The Chamber to Help Maintain the Shape of The Plastic Product.

Depending On the Size of The Pipe, The Cooling System of The Vacuum Sizing Machine Can Be Cooled by Spray Cooling. Generally, Full Immersion Is Required When the Pipe Diameter Is Small, And Spray Cooling Is Appropriate When the Pipe Diameter Is Large.

After Cooling, The Plastic Product Passes Through the Final Chamber. The Rollers Help Guide the Plastic Through the Vacuum Setting Machine.
