Problems solved by technology

[0003] In order to solve the problem of existing winding, the present invention has the following problems: firstly, single-layer winding is non-multiple tangent point winding, so that the overlapping effect of metal wires is not good, and the rigidity of the metal oil filter net after sintering is poor; Randomness will lead to uneven mesh size of the oil filter screen and a high reject rate; thirdly, the accumulation of metal wires at the end of the metal oil filter screen is serious during multi-layer winding, which is likely to cause falling wire slippage and seriously affect the winding accuracy. A metal oil filter net is now provided with a multi-layer superimposed winding forming method. The specific technical solution to solve the above problems is as follows:

specific Embodiment approach 1

[0012] Specific implementation mode one: the steps of this implementation mode are as follows:

[0013] Step 1. Design a cylindrical mandrel that meets the length and thickness according to the requirements;

[0014] Step 2. Use the HG-2 nozzle large-scale numerical control fiber winding machine to press the formula

[0015] d 0 cos α = 3 K ( d 1 + d 2 ) 3 K + 1 - - - ( 1 )

[0016] Obtain the winding control code, and wind the cylindrical mandrel according to the winding method of multi-layer metal wire interlaced lap win...

specific Embodiment approach 2

[0018] Specific Embodiment 2: This embodiment will be described in conjunction with FIG. 5 . In this embodiment, the diameter D of the mesh die is 40mm, the winding length of the equal winding angle is 100mm, the number of circumferential meshes (3K+1) is 13, and the bandwidth is d 0 It is 3.14mm, and a six-axis CNC winding machine is used to reciprocally wind 3 layers. When other parameters are the same, there is no accumulation at the end (as shown in Figure 5). Other steps are the same as in the first embodiment.

[0019] From the perspective of the cross-section, the order of the netting is as follows: starting from the first point, it is wound in a counterclockwise order. After the second layer of winding is completed, the 2k+1 point will fall at the two-thirds of the belt spacing on the right side of the first point, and the last point, namely the 3k+1 point, will fall at the Kth doffing point. As shown in Figure 3, 2, 1, and K in the figure are the doffing points of t...

Abstract

The invention relates to a multilayer coiling shaping method of metal oil filter network. wherein, it comprises that designing post core mould; using d0cosalpha=3K(d1+d2) / 3K+1 to control HG-2 ejection large digit control fiber coiling machine, to calculate the coil control code; via multi-tangent-point multilayer metal wire alternative coiling method, coiling the post core mould; (3), sintering coiled metal oil filter network, removing core mould, shearing over section, coiling into metal oil filter network. The invention has better rigidity, multilayer coiling, uniform network, non stack at end, and high coiling accuracy.

Description

technical field [0001] The invention relates to a winding forming method of a metal oil filter net. Background technique [0002] The metal oil filter screen formed by winding is usually wound with a single metal wire, which is in the shape of a tube. The metal wire is wound out from the yarn package, and the tension of the metal wire is controlled by a tensioner; the movement of the yarn output swing head is a synthesis of multi-coordinates according to the winding law. Movement, to control the winding track of the metal wire, so that the metal wire is wound to the surface of the mandrel to form a mesh. The existing metal oil screen winding has the following disadvantages and deficiencies: First, the single-layer winding is non-multi-tangential winding, which makes the metal wire lap joint effect not good, and the rigidity of the oil filter screen after sintering is poor; Overlapping makes the mesh size random, which will lead to uneven mesh size of the oil filter and high...
