Description
Technical Field
The utility model relates to the technical field of welding heads, in particular to an articulated polyurethane welding head.
Background
Automotive pumping units typically operate in an up-stroke and a down-stroke. When the oil pumping equipment operates, the oil pumping equipment is subjected to alternating load, the borne load is suddenly high and suddenly low, fatigue stress can be generated during long-term operation, and the equipment is damaged. In order to ensure the stable operation of equipment, a balancing weight is usually required to be additionally arranged on a crank according to the condition, so that the underground gravity is equivalent to the crank gravity, the balancing rate of the pumping unit reaches the qualified technical requirement of 85% -115%, the friction loss strength is high in the prior art, the conventional device, the original movable joint is a rubber bushing, the rubber bushing is not wear-resistant, abnormal sound is easy to occur, the service life is short, and therefore, the balancing rate is required to be adjusted according to the change of an oil well.
Disclosure of Invention
The utility model mainly solves the technical problems existing in the prior art and provides an articulated polyurethane welding head.
In order to achieve the above purpose, the utility model adopts the following technical scheme that the movable joint polyurethane welding head comprises a movable joint, the outer circumference of the movable joint is provided with a concave surface, the section of the concave surface is an arc shape which is downwards concave from two ends of the movable joint to the middle of the movable joint, the inside of the movable joint is provided with an inner connecting bush, the bush extends out of the end face of the movable joint for four to five centimeters, the inner connecting bush is made of the polyurethane bush, the inside of the inner connecting bush is provided with a welding pipe, and the side face of the movable joint is welded with a threaded column.
Preferably, the outer side of the joint is sprayed with electrostatic powder.
Preferably, the threaded post is welded to the outside of the joint by means of laser welding.
Preferably, the welding surface between the joint connection and the threaded post is smooth.
Advantageous effects
The utility model provides an articulated polyurethane weld joint. The beneficial effects are as follows:
(1) The movable joint polyurethane welding head is characterized in that force is uniformly dispersed to the inner connecting bushing in the matched use process, so that the wear resistance is improved, the ageing resistance is long in service life, and the vibration of the whole car is stably reduced.
