Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem of the production and processing of the existing large metal valve body, the first step is to raise the temperature of the metal block first, so that it can be beaten by a hydraulic machine, so that it can be conveniently made into a predetermined valve body However, when the hydraulic machine beats the red-hot metal block, it needs to be manually observed on one side, and the beating command is sent to the staff who control the hydraulic machine and the fixture. The red-hot metal block will not only The splashing of metal shavings on the outside may accidentally injure observers, and visual observation may misjudge the beating shape of the metal block, resulting in the need for multiple sets of remedial operations in the later stage, and when the existing metal valve body is produced and processed, the casting valve Bubbles and pores are prone to appear on the body base, and the scrap rate is about 40% or more. A production and processing method for the valve body is provided

Embodiment 1

[0028] A method for producing and processing a valve body, comprising:

[0029] Step 1: Put the metal block into the heating furnace for heating, make it burn red, and take it out after it has the ability to deform;

[0030] Step 2: Place the removed metal block under the hydraulic press, clamp it with the clamp, beat it with the hydraulic machine, and observe the beaten metal block with electronic eyes instead of human eyes, and communicate the shape data of the metal block to the control personnel;

[0031] Step 3: After hammering the metal valve body to make it have the shape characteristics of the metal valve body, cast the valve base, control the temperature and gas production, make it shape, and increase the height of the mold;

[0032] Step 4: After the production of the valve base is completed, the valve body and the base are processed and welded separately, and the air tightness is repeatedly tested to make it meet the sealing standard.

[0033] In the present invent...

Embodiment 2

[0035] The heating furnace in step 1 can be a large-scale intermediate frequency diathermy furnace, which is heated step by step from 700°C to 1200°C. The temperature is controlled and kept for 2-3 hours, and then taken out with a control fixture.

[0036] In the present invention, the output end of the control jig is electrically connected to a controller, which can control the clamping force and the direction of rotation. When the hydraulic press presses the metal block, it is clamped and turned over by the jig.

Embodiment 3

[0038] In the second step, the hydraulic press is a 500-800-ton hydraulic press, and electronic eyes are installed on the opposite, upper, lower, and rear sides of the pressing platform. The number of electronic eyes is multiple groups, and the output terminals of the electronic eyes are electrically connected with 2D image display module, 3D model reconstruction module, 3D graphics display module, comparison module, analysis module and control module.

[0039] In the present invention, the electronic eye adopts a shutter shooting type electronic eye, which can transmit the instantaneous photo of the pressed metal block to the 2D image display module and display it through the screen wall.

Abstract

The invention discloses a production and processing method of a valve body, which relates to the field of valve bodies, comprising: step 1: putting a metal block into a heating furnace for heating, making it red-hot, and taking it out after being deformable. The present invention realizes the replacement of human observation orders by electronic eyes and avoids the problem of pressing and beating metal blocks by hydraulic presses through multiple sets of electronic eyes, 2D image display module, 3D model reconstruction module, 3D graphic display module, comparison module, analysis module and control module. At times, red-hot metal shavings splash and hurt observers, and through the 3D model reconstruction module, comparison module, and analysis module, the machine can simulate and analyze the shape of the pressed and hammered metal block, so as to issue more accurate control commands and avoid the naked eye. Inaccurate observations lead to subsequent remediation.

Description

technical field [0001] The invention relates to the field of valve bodies, in particular to a production and processing method of a valve body. Background technique [0002] Metal valves refer to valves made of different metal materials. Valves are used in industries such as food biscuit industry, instant noodle and rice noodle industry, various quick-frozen food dehydration line equipment, and glass product industry. They can be used to control air, water, steam, and various corrosions. The flow of various types of fluids such as aggressive medium, mud, oil, liquid metal and radioactive medium. [0003] When the existing large-scale metal valve body is produced and processed, the first step is to heat up the metal block so that it can be hammered by a hydraulic machine, so that it can be easily made into the approximate shape of the predetermined valve body, but the hydraulic machine is hammering When a red-hot metal block is fired, it is necessary to observe it manually o...
