Product Description

Traction pin abrasion value in semi car train operation, traction with the touch of traction pin parts will attack different degree of wear and tear, traction pin price, wear to a certain degree of each parts need to repair, replace, because of the specific characteristics of structure of traction a locking mechanism, the general drawing a locking mechanism locking block does not need to replace, It only needs to be adjusted to compensate for the clearance, so traction pins are replaced in most cases. Some manufacturers have no rules in this respect, and let users use them at will. Once the traction pin is worn too much, it will cause the car train connection to be unreliable and increase the unsafe factors in the transportation process. Therefore, tong Xin Precision Forging company believes that the wear value of traction pin should be regulated. Because traction and traction pin combination is the semi-trailer train cars from its important parts, we hope that relevant departments for the above problems existing in the actual take notice, as soon as possible to revise the corresponding specification, in the right guidance traction traction pin of the production and use, prevent the semi-trailer car unsafe hidden danger in the train.



Traction pin processing and production process


Traction pin processing production process in simple terms, traction pin production in accordance with the following procedures:

1) Steel selection. Generally, clean low alloy steel with stable chemical composition is used as the material of traction pin. 40 chrome round steel is used in the market.

2) forging. Cold heading forging is generally used. The deformation of materials should be paid attention to during forging. Attention should be paid to dimension inspection, magnetic flaw detection and macro immersion before and during forging.

3) Product inspection and heat treatment.

The grinding traction pin of the trailer traction pin is one of the key parts connecting the tractor and the semi-trailer in the semitrailer train. The poor wear should be replaced in time.
