Background technique
In the mechano-electronic field, the oil cylinder cylinder is used widely, and it comprises parts such as front end housing, cylinder barrel, back cylinder cover, piston, piston rod and guide sleeve.Traditional processing technology is earlier each several part to be processed respectively, then cylinder barrel, cylinder cap is fused by certain Placement.Fig. 1 is a single-piston rod hydraulic jack structural representation, cylinder body one end and cylinder bottom welding, and the other end adopts with cylinder cap and is threaded.In addition, cylinder body and the Connecting format of cylinder cap also have that pull bar is connected, flange connects, snap ring connects, outside thread connects, internal thread connects.Flange such as high-voltage oil cylinder connects, and Fig. 2 is the flanged connecting structure schematic representation of cylinder body and end cap, does upper flange plate on the cylinder body earlier, uses screw and end cap fastening again.
Therefore, with the oil cylinder cylinder that conventional method is made, though its Placement reaches the purpose that is connected and fixed, sealing effect is not ideal enough.Realize connecting technologies such as will adopting welding, not only complex process also may cause adverse consequencess such as block distortion.And steel cylinder and cylinder cap and link thereof be all by metal forming, rough surface, and weight is bigger, and boundary dimension is also big, and integral body seems outward appearance dullness, not attractive in appearance, gives the sensation of a kind of heaviness of people.
Summary of the invention
The drawback of bringing for the manufacture method that solves traditional oil cylinder cylinder, it is succinct to the invention provides a kind of processing technology, easily, cost of production is low, the efficient height, can produce good sealing effect, the manufacture method of cylinder body of the oil cylinder cylinder of the plastics of enough intensity, rigidity, durability and high dimensional accuracy and metal one-time moulding is arranged.
The present invention is achieved by the following technical solutions:
The invention provides a kind of manufacture method of cylinder body of oil cylinder cylinder, comprise the steps:
1. process metal cylinder barrel by the required size specification, go rough processing.
2. make a cover cylinder body plastic mould, this mold cavity is housing structure, comprise metal cylinder barrel and back cylinder cover, back cylinder cover is connected an end of metal cylinder barrel, step metal cylinder barrel is 1. put into mould as inserts, the mould that is embedded with metal cylinder barrel is put into forming equipment, add plastics, go out the metal cylinder barrel embedding by the compression-moulding methods disposal molding and cylinder body on back cylinder cover.
As a kind of improvement of the present invention, the 2. described housing structure of step also comprises the flange that is connected on the metal cylinder barrel front end outside, goes out the metal cylinder barrel front end outside by the compression-moulding methods disposal molding and goes up the cylinder body that flange in embedding.
As another kind of improvement the of the present invention, 1. step also processes metal by the required size specification and connects mouth, the 2. described housing structure of step, comprise that also the metal that is embedded on the back cylinder cover connects mouth, described metal is connect mouth put into mould as inserts, put into forming equipment with being embedded with the mould that metal cylinder barrel and metal connect mouth, add plastics, go out the back cylinder cover embedding by the compression-moulding methods disposal molding and the cylinder body that metal connects mouth.
As another improvement of the present invention, can also adopt the structure of claim 2 qualifying part, 1. step also processes metal by the required size specification and connects mouth, the 2. described housing structure of step, comprise that also the metal that is embedded on the back cylinder cover connects mouth, described metal is connect mouth put into mould, put into forming equipment being embedded with the mould that metal cylinder barrel and metal connect mouth as inserts, add plastics, go out the back cylinder cover embedding by the compression-moulding methods disposal molding and the cylinder body that metal connects mouth.
The 2. described forming equipment of step of the present invention is injection machine or compression molding machine, described plastics are thermoplastic or thermosetting plastics, described plastics are thermoplastic or thermosetting plastics, described compression-moulding methods is injection moulding or compression molding, and the material that described metal cylinder barrel and metal connect mouth is 35 steel or 45 steel.
Compare with classical production process, the invention has the beneficial effects as follows:
1, the size of made cylinder body is accurate, and good sealing effect has enough intensity, rigidity and durability.
2, simplified processing technique, easy to manufacture, cost is low, the manufacturing efficiency height.
3, can dwindle the boundary dimension of oil hydraulic cylinder as far as possible, accomplish compact structure, reach the outward appearance grace, in light weight, the effect of energy saving.
