A butterfly valve assembly machine stem hydraulic automatic combination device and its combination method

Abstract

Provided are an automatic electrohydraulic control butterfly valve assembly machine and an assembly method thereof. Use is convenient, assembly procedures are less, operation is fast, and the host machine pressure can be regulated in time according to butterfly valves with different types and specifications; the working efficiency and quality are greatly improved, and the economic benefit is good; because a PLC is adopted to perform automatic control, the man-machine security coefficients are high, the assembly is accurate, a large amount of time and a large number of energy resources are saved, the maintenance cost and the production cost which are caused by wear are reduced, the engine performance is obviously improved, the service life is obviously prolonged, and popularization is convenient. The automatic electrohydraulic control butterfly valve assembly machine is composed of a butterfly assembly workbench, an infrared induction security device, a tooling base, an assembly machine stand column, a pressure head tool, a pressure regulation valve device, an upper oil cylinder support frame, a pressure gauge device, an upper hydraulic cylinder device, a PLC control box device, control buttons, an electrical box device, a butterfly valve tool, a locking nut mechanism and a pressing lead screw assembly.

Problems solved by technology

[0002] At present, butterfly valves are widely used in chemical engineering, water conservancy, fire protection, engineering and other pipeline machinery fields due to their advantages of convenient control, safety, wear resistance, and engineering; with the rapid development and renewal of various fields, existing butterfly valves The processing and manufacturing of butterfly valves can no longer meet the demand; traditional butterfly valve manufacturers, when producing and assembling the valve stems of butterfly valves, are basically assembled by hand, that is, the rubber sleeve, butterfly plate and valve stem are hammered by hand. Into the valve body, there are the following shortcomings: different processes require different people to assemble, high technical requirements; time-consuming, from the first process to the last process, it takes more than 10 minutes; laborious, from the first process to the last One-step process, labor-intensive; due to the requirements of processing standards, it is easy to be biased, damaged, deformed and other losses during the assembly process, and it is often reworked many times to meet the standard; the efficiency is low

However, the existing valve stem assembly machinery of butterfly valves is already very advanced, but the operation is not convenient enough. The main control hydraulic pressure cannot be adjusted and controlled in time according to the model and specification according to the processing standards. Once a failure occurs, the repair and maintenance costs will be increased. , which reduces work efficiency; due to the huge power of the processing machinery, when assembling and assembling valve stems of different types and specifications, the safety factor of the existing butterfly valve assembly machine host is low, resulting in the use of existing valve stems of different specifications and models. When some butterfly valve assembly machines are assembled and pressed together, deformation will occur, which will affect the quality of the butterfly valve; then, when assembling the valve stem of the butterfly valve, the finished product rate of the processed butterfly valve needs to be further improved to reduce the consumption of additional energy resources; for a long time, it is The bottleneck in the development of this field affects the development of butterfly valve assembly machinery, which is difficult to meet the needs of the market and users, and needs to be improved urgently
