The towline is mainly divided into two major types of steel towline and plastic towline. The steel towline can be customized by steel and aluminum combination. The plastic towline is also called engineering towline and tank chain. This article mainly introduces the basic knowledge of plastic towline.
First, the use and characteristics of plastic towline
1. Each section of the plastic towline can be opened for easy installation and maintenance. And the noise generated during exercise is low, wear-resistant, and can move at high speed.
2. The plastic towline is suitable for use in the reciprocating motion, and can play the role of pulling and protecting the built-in cable, oil pipe, air pipe and water pipe.
3, plastic towline has been widely used in CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machines, robots, overweight transportation equipment, automated warehouses and other fields.
Second, the structure of the plastic towline
1. The shape of the plastic towline is similar to that of the tank chain. It is composed of many unit links, and the links can be rotated freely.
2. The unit chain link of the plastic towline is composed of left and right chain plates and upper and lower cover plates. Each section of the plastic towline can be opened, which is convenient for assembly and disassembly. It is not necessary to thread the cable. After opening the cover plate, the cable, oil pipe and air pipe can be put. Put water pipes and so on into the towline.
3. The inner height, outer height and pitch of the same series of plastic towline are the same. It is more convenient that the inner width and bending radius R of the drag chain can have different choices.
4. In addition, the plastic drag chain may be used to separate the sheets, and the space inside the chain may be separated as needed.
Third, the basic parameters of plastic towline
(1) The material used in the plastic towline is reinforced nylon, which has high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardant, stable performance at high and low temperatures, and can be used outdoors.
(2) Resistance: resistant to oil and salt, and with a certain acid and alkali resistance.
(3) Running speed and acceleration: The maximum speed can reach 5 m / s, and the maximum acceleration can reach 5 m / s (the specific speed and acceleration depend on the operating conditions).
(4) Operating life, up to 5 million reciprocating movements under normal crowding use (specific life depends on operating inertia).
