Pipe pressing device for galvanizing machine

Abstract

The invention belongs to the field of galvanizing and processing of steel pipes and specifically relates to a pipe pressing device for a galvanizing machine. The pipe pressing device comprises a guide sliding sleeve, a pressing rod, a pressing plate part and a power part, wherein the pressing rod is arranged on the guide sliding sleeve and is capable of moving up and down along the guide sliding sleeve; the pressing plate part is arranged on the bottom end of the pressing rod; the power part is connected with the top end of the pressing rod; the pressing plate part comprises a pressing plate base connected with the bottom end of the pressing rod and a pressing plate arranged on the bottom of the pressing plate base; a plurality of pressing plate grooves with arc sections in parallel arrangement are concavely formed in the pressing plate; the pressing plate grooves are connected through an arc transition section; a galvanizing pond is provided with a pipe pressing device; after galvanizing, a large amount of air still exists in a pipe cavity of a steel pipe with an external diameter of 20-22mm and a wall thickness less than or equal to 1.6mm, so that the rear end of the steel pipe is smoothly pressed downwards; the inclination angle of the pressed steel pipe is similar to that of a transmission device, so that the steel pipe is smoothly transmitted out of the galvanizing pond; the faults that the steel pipe is bent or the device is jammed and the like cannot occur in the transmission process, so that the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of galvanizing processing of steel pipes, and in particular relates to a pipe crimping device for a galvanizing machine. Background technique [0002] In the steel pipe galvanizing process, the front end of the galvanized steel pipe will be placed on the conveyor device that extends into the galvanizing pool obliquely, and will be sent out of the galvanizing pool by the conveyor device. Most types of steel pipes can be sent out of the galvanizing pool smoothly. When the steel pipe with large inner diameter is galvanized, the zinc liquid easily enters the steel pipe. After galvanizing, there will not be a lot of air in the steel pipe, and the steel pipe will sink with its own gravity. The steel pipe with a smaller inner diameter has a smaller lumen. Although the zinc liquid is not easy to pour into the lumen, even if there is air in the lumen after galvanizing due to the small diameter of the pipe, it is not enough to ...

[0002] In the steel pipe galvanizing process, the front end of the galvanized steel pipe will be placed on the conveyor device that extends into the galvanizing pool obliquely, and will be sent out of the galvanizing pool by the conveyor device. Most types of steel pipes can be sent out of the galvanizing pool smoothly. When the steel pipe with large inner diameter is galvanized, the zinc liquid easily enters the steel pipe. After galvanizing, there will not be a lot of air in the steel pipe, and the steel pipe will sink with its own gravity. The steel pipe with a smaller inner diameter has a smaller lumen. Although the zinc liquid is not easy to pour into the lumen, due to the small diameter of the pipe, even if there is air in the lumen after galvanizing, it is not enough to float the steel pipe

In the actual galvanizing process, after galvanizing a steel pipe with an outer diameter of 20-22mm and a wall thickness of 1.6mm or less, there will be a large amount of air in the steel pipe, which is enough to offset the weight of the steel pipe and suspend the steel pipe in the pool. The rear end is tilted, so that when the conveyor is transported along the inclined conveyor, the front end of the steel pipe will be against some parts of the conveyor, causing the steel pipe to bend or get stuck during the conveying process
