Abstract
The invention provides a method for forming a hydraulic valve and relates to the field of the mechanical production and machining technology. The method comprises the following steps: taking a valve opening as a center, taking a formed rectangular valve diagonal line as a radius, determining the section material size of blanking round steel, feeding and programming forming program on a numerically-controlled lathe and machining an excircle and the valve opening on the lathe till the appearance of a rectangular valve is machined and is formed one time. The process is convenient and quick and can select a proper tool array to machine according to cartridge valves with different flow rates without a special tool, thereby saving the production cost, reducing the production cycle and also being favor of reducing the production power consumption. The method is suitable for machining valve openings of domestic and foreign cartridge valves and in particular suitable for middle and small-sized hydraulic system machining enterprises.
Description
Technical field
The present invention relates to the machinery production processing technique field, the shaping production method of special hydraulic valve block.
Background technology
The inserted valve volume is little, compact conformation, applying flexible, be widely used in boats and ships, metallurgical, in the hydraulic systems such as engineering machinery, general shape is a rectangle, and valve opening wherein is circular, and the requirement on machining accuracy to valve opening is very high, must on radial drill or milling machine, bore by the configuration molding cutter, hinge, a clamping moulding of several instrument technology of tapping, and the molding cutter price is higher, and the production cycle is longer, can not satisfy fast pace, low consumption, high efficiency, production requirement cheaply, caused the hydraulic system cost up, delay delivery date, influenced the credit worthiness of enterprise.
The object of the invention is to propose a kind of a kind of forming method that need not to adopt special fixture, High-efficient Production hydraulic valve block.
Summary of the invention
The present invention includes following steps:
1, takes off the section material of the length of shaping valve piece from round steel;
2, processing excircles on lathe;
3, the processing valve opening concentric on lathe with cylindrical;
4, on lathe, process the valve piece profile of rectangle.
Thereby the inserted valve valve opening processing technology that the present invention adopts is by changing the block-shaped change technological method for processing that reaches of valve: the present invention is the center with the valve opening, with the rectangle valve piece diagonal after the moulding is radius, determine the section material size of blanking round steel, lead to and on numerically controlled lathe, work out journey moulding program, on lathe from processing excircles, valve opening, until the valve piece profile that processes rectangle, one-shot forming, technology of the present invention is convenient and swift, can select suitable blade row to process according to the inserted valve of different flow, need not the dedicated tool frock, save production cost, reduced the production cycle, also be beneficial to the reduction energy consumption.That the present invention is fit to is homemade, the processing of import inserted valve valve opening, is particularly suitable for middle-size and small-size hydraulic system processing enterprise.
The specific embodiment
Production process:
1, numerically controlled lathe is carried out programming.
2, take off the cylindrical segment material of the length of shaping valve piece from round steel.
3, start numerically controlled lathe, processing excircles, the valve opening concentric with cylindrical on lathe successively process the valve piece profile of rectangle at last.
Claims (1)
1. a kind of forming method of hydraulic valve block is characterized in that may further comprise the steps:
1) takes off the section material of the length of shaping valve piece from round steel;
2) processing excircles on lathe;
3) the processing valve opening concentric on lathe with cylindrical;
4) on lathe, process the valve piece profile of rectangle.
