Embodiment 1

[0087] The processing method of mandrel spraying lubricant described in the present embodiment, steps are as follows:

[0088] (1) Add the lubricant to be sprayed into the lubricant storage tank 1. If pre-mixing is required, just mix the components evenly; turn on the delivery pump 2, adjust the output pressure to 0.1-0.2MPa, and the lubricant is self-lubricating The lubricant storage tank 1 is pumped out into the delivery pump 2. At this time, the pressure of the pressure regulating valve of the delivery pump 2 is continuously increased, so that the lubricant rises to the set pressure of 8MPa during the continuous movement of the delivery pump 2, and the lubricating agent after being pressurized The agent flows through the filter 3 and the pressure-stabilizing accumulator 4, and reaches the front end of the spray ring 7, and the gas-liquid pressure balance is reached in the delivery pump 2, and the pressure value in the system remains unchanged;

Embodiment 2

[0093] The processing method of mandrel spraying lubricant described in the present embodiment, steps are as follows:

[0094] (1) Add the lubricant to be sprayed into the lubricant storage tank 1. If pre-mixing is required, just mix the components evenly; turn on the delivery pump 2, adjust the output pressure to 0.1-0.2MPa, and the lubricant is self-lubricating The lubricant storage tank 1 is pumped out into the delivery pump 2. At this time, the pressure of the pressure regulating valve of the delivery pump 2 is continuously increased, so that the lubricant rises to the set pressure of 12MPa during the continuous movement of the delivery pump 2, and the lubricating agent after being pressurized The agent flows through the filter 3 and the pressure-stabilizing accumulator 4, and reaches the front end of the spray ring 7, and the gas-liquid pressure balance is reached in the delivery pump 2, and the pressure value in the system remains unchanged;

Embodiment 3

[0099] The processing method of mandrel spraying lubricant described in the present embodiment, steps are as follows:

[0100] (1) Add the lubricant to be sprayed into the lubricant storage tank 1. If pre-mixing is required, just mix the components evenly; turn on the delivery pump 2, adjust the output pressure to 0.1-0.2MPa, and the lubricant is self-lubricating The lubricant storage tank 1 is pumped out into the delivery pump 2. At this time, the pressure of the pressure regulating valve of the delivery pump 2 is continuously increased, so that the lubricant rises to the set pressure of 10MPa during the continuous movement of the delivery pump 2, and the lubricating agent after being pressurized The agent flows through the filter 3 and the pressure-stabilizing accumulator 4, and reaches the front end of the spray ring 7, and the gas-liquid pressure balance is reached in the delivery pump 2, and the pressure value in the system remains unchanged;

Abstract

The invention relates to the technical field of mandrel spraying, in particular to a process method and a device for spraying a lubricant on a mandrel. The process for spraying lubricant on the mandrel includes the following steps: the lubricant is sprayed on the surface of the mandrel under the condition of 8-12MPa, and the spraying covers 360° in the circumferential direction of the mandrel. The device includes a lubricant storage tank, a delivery pump and a spray ring, the lubricant is pumped to the spray ring through the delivery pump, and the inner wall of the spray ring is provided with nozzles. The invention adopts a high-pressure spraying method to fully atomize the lubricant, has strong adsorption capacity, improves the adsorption of the lubricant on the surface of the mandrel, and can form a dense protective lubricating film on the surface of the mandrel. The lubricant atomized under high-pressure conditions can Spray evenly to the surface of the mandrel without accumulation, and the spraying covers the mandrel 360° around the circumference to improve the uniformity of the distribution of the mandrel lubricant, avoiding the existence of positions where the lubricant is not sprayed or repeatedly sprayed .

Description

technical field [0001] The invention relates to the technical field of mandrel spraying, in particular to a process method and a device for spraying a lubricant on a mandrel. Background technique [0002] With the improvement of the requirements for the seamless pipe production products of the pipe jacking unit, the requirements for the core rods of key deformation tools are also becoming more and more stringent. The lubrication effect of the mandrel surface directly affects the product quality. Mandrel lubricants are widely used in mandrel lubrication. Mandrel lubricants are finally adsorbed to the surface of mandrels through various methods to form a lubricating effect. The coverage uniformity, coverage depth and adsorption effect of the mandrel lubricant on the mandrel surface play a vital role in the lubricating effect of the mandrel. [0003] In the prior art, a columnar oil column is used to lubricate the mandrel to improve the lubricity of the mandrel. However, the...
