Expanding mill component installing device and method

Abstract

The invention relates to the field of expanding mills, in particular to an expanding mill component installing device and method. The installing device comprises a transport cart and a tool installed on the transport cart, wherein the tool is used for assisting in the installation of expanding mill components, the transport cart comprises wheels and a cart frame arranged on the wheels and connected with the wheels, a first positioning pin used for fixing the tool is arranged on the upper end face of the cart frame, and a first positioning hole is formed in the bottom of the tool. According to the expanding mill component installing device, the transport cart is used for driving the tool to install the expanding mill components, the components to be installed are well supported by the tool and the transport cart, the tool is positioned by the first positioning pin on the transport cart, installation accuracy is ensured, the cantilever phenomenon is avoided for the expanding mill components such as an expanding head, and safety and reliability are achieved; meanwhile, the transport cart is used for transportation, a large amount of high-intensity physical labor is avoided, and installation efficiency is improved.

Description

technical field [0001] The invention relates to the field of diameter expanding machines, in particular to an installation device for parts of the diameter expanding machine and an installation method thereof. Background technique [0002] The diameter expanding machine belongs to straight seam metal welded pipe shaping equipment. It uses a cone diameter expansion head to expand in the steel pipe. Through the segmented mechanical extrusion process, the forming pressure and welding stress of the welded pipe can be eliminated, and the straight seam metal welded pipe can be guaranteed. For the purpose of keeping the diameter of the entire length section consistent, the equipment is composed of an expanding head, a tie rod, a working sleeve, a fixed seat, an oil cylinder, a lubrication station, a bench, a hydraulic station and an electric control system. figure 1 It is a schematic diagram of the structure of the expansion head in the prior art, usually about two meters long, and...

AI Technical Summary

Problems solved by technology

This installation method has the following disadvantages: the expansion head is hoisted by the crane for lifting and rotating movements, the expansion head is in a cantilever state, easy to shake when driving, poor safety and reliability, and installation accuracy is not easy to control

It can be seen that this method of manually lifting the mold to install the mold is slow and requires 3-4 people to complete. The large mold has a large volume and high weight, and the labor intensity of the operator is very high.
