Multi-cutter processed numerically-controlled double-slider power head of valve body

Abstract

The invention relates to a multi-cutter processed numerically-controlled double-slider power head of a valve body. The power head comprises a ram seat, a square ram, a flat turning disc, sliders, a main spindle box, a differential feeding box, a tool rest mechanism and the like, wherein the square ram is mounted on the ram seat; the flat turning disc is connected to the front end of the square ram; the two sliders are mounted on the flat turning disc; tool rests are symmetrically fixed on the flat turning disc; the main spindle box is connected to the rear end of the square ram; the differential feeding box which is connected with a servo motor is connected to the other end of the main spindle box; a main spindle alternating current variable frequency motor is connected to the upper end of the main spindle box through a connector; a shifting fork oil cylinder on one side opposite to the motor is connected onto the main spindle box; and a main spindle penetrates through the square ram, one end of the main spindle is connected onto the flat turning disc, the other end is connected into the main spindle box, and a mandrel is connected to the center of the main spindle in a sleeving manner. The multi-cutter processed numerically-controlled double-slider power head of the valve body has high processing accuracy, reduces the labor intensity of workers, and improves the production efficiency and the product qualification rate.

Description

Technical field: [0001] The invention relates to a numerically controlled double-slider power head for multi-knife machining of a valve body. It is mainly used for machining pump and valve flanges. The valve bodies suitable for processing in the present invention include: gate valves, globe valves, check valves, butterfly valves, pressure reducing valves and other valve body parts with flanges. Background technique: [0002] At present, domestic pump and valve manufacturers usually use ordinary lathes, vertical lathes, CNC machine tools or simple CNC machine tools restructured from ordinary universal machine tools to process valve body flanges, but CNC machine tools also have limitations, mainly valve body parts. The size of the blank and the height of the sprue vary greatly, which brings great difficulty to the programming of CNC machine tools. When processing the valve body, these machine tools clamp the end of the flange of the valve body blank on the chuck of the machine...

AI Technical Summary

Problems solved by technology

The use of multi-tool cutting can solve the problem of multiple feeds and improve the processing quality, because usually the valve body processing process should be divided into rough machining and finishing machining. The rough machining has a large cutting allowance, large cutting force, and high cutting heat. After rough machining, due to the redistribution of internal stress, the workpiece is deformed greatly, so finishing after rough machining can make the workpiece obtain higher precision and roughness.
