Abstract
This invention refers to valve block with optional shape cavity and making method, which contains at least two overlapped thin sheets with holes and slots, said method containing machining holes, slots and positioning point at relative point in 1-2mm thickness metal sheet according to design demand, overlapping said metal sheet whose holes or slots forming shape cavity, welding by vacuum brazing, in said invention, the holes and slots can be machined by punch press or other machine tool to simplify the complex working technology in current valve block.
Description
Technical field
The present invention relates to a kind of free-cavity valve block and preparation method thereof, is the parts in the relevant device Hydraulic Power Transmission System pipeline, belongs to electromechanical integration technology area.
Background technique
At existing press machine, in bender and the relevant device Hydraulic Power Transmission System, for the ease of the installation of various control units and the control of action, in pipeline, understand the fit on valve piece of steel one by one, die cavity in these valve pieces is of all kinds, what have is very complicated, existing processing method is to utilize machining center or numerical control drilling machine to process, some die cavity more complicated, also need other processing technology hole, and then the relevant complex-shaped surface mould of processing, after machining, with plug auxiliary hole is blocked again die cavity, processing technology is very complicated, processing cost is also very high, also exists hole, right angle liquid flow properties poor in addition, shortcomings such as deep hole cleaning difficulty.
Summary of the invention
The objective of the invention is at existing valve piece processing technology complexity, processing cost is higher, also exists hole, right angle liquid flow properties poor, shortcomings such as deep hole cleaning difficulty, provide processing technology simple relatively, a kind of free-cavity valve block that processing cost obviously reduces and preparation method thereof.
The purpose of this utility model is achieved through the following technical solutions, and a kind of free-cavity valve block is characterized in that described valve piece constitutes by being no less than two thin pieces stacks, and the region of interest of corresponding thin piece adds hole or groove are set; A kind of free-cavity valve block making method, it is characterized in that described method mainly comprise with thickness be each metal foil piece of 1～2mm by designing requirement at region of interest machining hole or groove, after each thin piece stack, its hole or groove constitute the die cavity that adheres to specification, and weld with vacuum brazing again.
The present invention is designed to the valve piece to be made of some thin piece stacks, designing requirement according to die cavity, utilize punch press or miscellaneous equipment machining hole or groove on each relevant thin piece, after some thin pieces superpose in order, the die cavity that hole on its relevant thin piece or groove constitute different shape, weld through vacuum brazing again, the present invention has simplified the processing technology of existing valve piece complexity greatly, become the hole of each monolithic or the simple processing of groove, simple in structure, combined and instant, reliable performance, greatly reduce processing cost, have very strong practicability and remarkable economic efficiency.
Description of drawings
Accompanying drawing 1 is this structural representation of invention;
Among the figure, 1 thin piece, 2 die cavities, 3 locating points.
Embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, the present invention constitutes after being superposeed in order by some thin pieces 1, designing requirement according to die cavity, machining hole or groove on relevant thin piece 1, at least be processed with two locating points 3 on each thin piece 1, locating point 3 on thin piece 1 one side is concave spherical surfaces, locating point 3 on the another side is protruding sphere, locating point 3 on thin piece 1 one side can also be a groove, locating point 3 on the another side is tongue, with all thin pieces 1 in order with utilize locating point 3 to superpose, hole on each thin piece 1 or groove constitute the die cavity 2 that adheres to specification, weld with the technology of vacuum brazing again, guarantee the generation of all die cavities 2 no leakage problems.
Claims (4)
1, a kind of free-cavity valve block is characterized in that described valve piece constitutes by being no less than two thin piece stacks, and the region of interest of corresponding thin piece is provided with hole or groove.
2, free-cavity valve block according to claim 1 is characterized in that at least also being provided with on each thin piece two locating points.
3, a kind of free-cavity valve block making method, it is characterized in that described method mainly comprise with thickness be each metal foil piece of 1～2mm by designing requirement through punch press or miscellaneous equipment at region of interest machining hole or groove and locating point, after each thin piece stack, its hole or groove constitute the die cavity that adheres to specification, and weld with vacuum brazing again.
4, free-cavity valve block making method according to claim 3 is characterized in that the locating point processing on the thin piece one side is concave spherical surface, and the locating point on the another side then is protruding sphere; Locating point on the thin piece one side can also be processed and be groove, and the locating point on the another side then is tongue.
