[0022] In order to form the finished mosaic block shown in Example 1, this solution adopts the following steps: S1: Select a profile 6 suitable for cold drawing. The profile 6 is a cylindrical or square structure. The profile 6 can be made of steel, such as 45 steel; S2: Figure 3 , 4 As shown, the profile in S1 is cold-drawn by a cold-drawing die and then cut into sections to form a first semi-finished product 1; the outer contour of the first semi-finished product 1 is substantially the same as the outer contour of the mosaic finished product 01, and the two side planes 011 of the first semi-finished product 1 have transverse textures 012 formed along the cold-drawing direction, the thickness of the first semi-finished product 1 is H1, the radius of the outer arc surface of the first semi-finished product 1 is R1, and the radius of the inner arc surface is r1; wherein H1>H, R1>R, r1 <r; S3: Figure 5 , 6 As shown, if the parallelism of the two end faces 018 of the first semi-finished product 1 after cutting does not meet the requirements, for example, it is greater than 4 microns, the first semi-finished product 1 is first placed on a milling machine for milling of the end face 018 and then placed on a grinding machine for grinding the end face 018 to form a second semi-finished product 2; if the parallelism of the two end faces of the first semi-finished product 1 after cutting is greater than 2 microns and less than 4 microns, the first semi-finished product 1 is placed on a grinding machine for grinding the end face 018 to form a second semi-finished product 2; the thickness of the second semi-finished product 2 is H2; wherein, H1>H2>H.

Then, the transverse opening of the suction hole 014 is completed, and the axis of the suction hole 014 is consistent with the radial direction of the cylinder body.

In order to further ensure the parallelism of the two end faces 018, the two end faces 018 of the fourth semi-finished product 4 are processed to form the fifth semi-finished product 5.

[0032] See also Fig.12 , 13Schematic diagram of the structure of the finished mosaic block in this embodiment, in which the thickness of the finished mosaic block 01 is H, the two side planes of the finished mosaic block 01 are planes 011, and there is a certain angle between the two planes 011. The plane 011 is provided with a transverse texture 012 and a longitudinal texture 013, and the transverse texture 012 and the longitudinal texture 013 are used to increase the bonding force with the lightweight material. The finished mosaic block 01 is provided with an air suction hole 014, a slide groove 015 and a spring hole 020 opened along the radial direction of the cylinder body, and the axes of the spring hole 020 and the slide groove 015 coincide with each other. A slide is slidably provided in the slide groove 015, one end of the slide is in contact with the spring (not shown in the figure) in the spring hole 020 and is squeezed by the spring, and the other end is in sliding and sealing contact with the piston (not shown in the figure) in the cylinder body; the radius of the outer arc surface 016 of the finished mosaic block 01 is R, and the radius of the inner arc surface 017 is r; Fig.13 The left and right sides are end faces 018; In order to form the mosaic block product 01 shown in Example 2, this solution adopts the following steps: S1: Select a profile 6 suitable for cold drawing, the profile 6 is a cylindrical or square structure, and the profile 6 can be made of steel; S2: Fig.14 , 15 As shown, the profile 6 in S1 is cold-drawn by a cold-drawing die and then cut into sections to form a first semi-finished product 1; the outer contour of the first semi-finished product 1 is substantially the same as the outer contour of the mosaic finished product 01, and the two side planes 011 of the first semi-finished product 1 have transverse textures 012 formed along the cold-drawing direction, the thickness of the first semi-finished product 1 is H1, the radius of the outer arc surface 016 of the first semi-finished product 1 is R1, and the radius of the inner arc surface 017 is r1; wherein, H1>H, R1>R, r1 <r。

[0034] Through the above steps, the parallelism of the two end faces 018 of the first semi-finished product 1 can be ensured, so that the subsequent processing of the suction hole 014, the slide groove 015, and the spring hole 020 is facilitated by taking the end face 018 as a reference.

[0035] like Fig.17As shown, in S3, after the second semi-finished product 2 is formed, the longitudinal textures 013 of the plane surfaces 011 on both sides of the second semi-finished product 2 are opened with the end surface 018 of the second semi-finished product 2 as a reference.

[0041] In the above steps, since the semi-finished product is clamped in S4 and S5, the two end faces 018 of the semi-finished product are bound to be scratched or clamped. In order to further ensure the parallelism of the two end faces 018, the two end faces 018 of the fourth semi-finished product 4 are processed to form the fifth semi-finished product 5.

Example 3

[0043] See also Fig.24 , Fig.25 3 is a schematic diagram of the structure of the finished mosaic block in this embodiment. The finished mosaic block 01 in this embodiment 3 is substantially the same as the finished mosaic block 01 in embodiment 2, except that the two side planes of the finished mosaic block 01 are planes 011, the two planes 011 are arranged in parallel, and an avoidance portion 021 is provided at the corner of the finished mosaic block 01.

[0044] In order to form the finished mosaic block shown in Example 3, this solution adopts the following steps: S1: Select a profile 6 suitable for cold drawing, the profile 6 is a cylindrical or square structure, and the profile 6 can be made of steel; S2: Fig.26 As shown, the profile 6 in S1 is cold-drawn by a cold-drawing die and then cut into sections to form a first semi-finished product 1; Fig. 27 As shown, the outer contour of the first semi-finished product 1 is substantially the same as the outer contour of the mosaic block finished product 01, the two side planes 011 of the first semi-finished product 1 are arranged in parallel, the two side planes of the first semi-finished product 1 have transverse textures 012 formed along the cold drawing direction, the thickness of the first semi-finished product 1 is H1, the radius of the outer arc surface 016 of the first semi-finished product 1 is R1, and the radius of the inner arc surface 017 is r1; wherein, H1>H, R1>R, r1 <r。

[0045] S3: Fig.28 , 29 As shown, if the parallelism of the two end faces 018 of the first semi-finished product 1 after cutting does not meet the requirements, for example, it is greater than 4 microns, the first semi-finished product 1 is first placed on a milling machine for end face milling and then placed on a grinding machine for end face grinding to form a second semi-finished product 2; if the parallelism of the two end faces 018 of the first semi-finished product 1 after cutting is greater than 2 microns and less than 4 microns, the first semi-finished product 1 is directly placed on a grinding machine for end face grinding 018 to form a second semi-finished product 2; the thickness of the second semi-finished product 2 is H2; wherein, H1>H2>H.

[0046] In the above steps, the parallelism of the two end faces 018 of the first semi-finished product 1 can be ensured, so that the subsequent processing of the air suction hole 014, the slide groove 015, and the spring hole 020 is facilitated by taking the end faces 018 as a reference.

[0047] like Fig.29 As shown, in S3, after the second semi-finished product 2 is formed, the longitudinal textures 013 of the plane surfaces 011 on both sides of the second semi-finished product 2 are opened with the end surface 018 of the second semi-finished product 2 as a reference.

[0054] In the above steps, since the semi-finished product is clamped in S4 and S5, the two end faces 018 of the semi-finished product are bound to be scratched or clamped. In order to further ensure the parallelism of the two end faces, the two end faces of the fourth semi-finished product 4 are processed to form the fifth semi-finished product 5.

[0055] S7: Fig.35 As shown, the fifth semi-finished product 5 is placed on a grinding machine, and the outer arc surface 016 and the inner arc surface 017 of the fifth semi-finished product 5 are ground until the size of the outer arc surface 016 and the inner arc surface 017 of the fifth semi-finished product 5 is ground to be consistent with the size of the mosaic block finished product 01.

[0056] In the above steps, the outer arc surface 016 and the inner arc surface 017 of the fifth semi-finished product 5 are ground to form the mosaic block finished product 01, ensuring that the outer arc surface 016 of the mosaic block finished product 01 is coplanar with the outer side surface of the cylinder body, and the inner arc surface 017 of the mosaic block finished product 01 is coplanar with the inner side surface of the cylinder body, ensuring that the mosaic block finished product 01 does not protrude from the inner and outer walls of the cylinder body. Example 4

[0057] See also Fig.36 , Fig.37 : is a schematic diagram of the structure of the finished mosaic block in this embodiment. The finished mosaic block in this embodiment is substantially the same as the finished mosaic block 01 in Example 3, except that a connecting hole 022 is provided at a corner of the finished mosaic block 01.

[0058] In order to form the finished mosaic block shown in Example 4, this solution adopts the following steps: S1: Select a profile 6 suitable for cold drawing, the profile 6 is a cylindrical or square structure, and the profile 6 can be made of steel; S2: Fig.38 As shown, the profile 6 in S1 is cold-drawn by a cold-drawing die and then cut into sections to form a first semi-finished product 1; the outer contour of the first semi-finished product 1 is substantially the same as the outer contour of the mosaic block finished product 01, as shown in FIG. Fig.40 As shown, the first semi-finished product 1 has transverse textures 012 formed along the cold drawing direction on the two side planes 011, and the thickness of the first semi-finished product 1 is H1. Fig.39 As shown, the radius of the outer arc surface 016 of the first semi-finished product 1 is R1, and the radius of the inner arc surface 017 is r1; wherein H1>H, R1>R, r1 <r。

[0059] S3: Fig.40 , 41As shown, if the parallelism of the two end faces of the first semi-finished product 1 after cutting does not meet the requirements, for example, it is greater than 4 microns, the first semi-finished product 1 is first placed on a milling machine for milling of the end face 018 and then placed on a grinding machine for grinding the end face 018 to form a second semi-finished product 2; if the parallelism of the two end faces 018 of the first semi-finished product 1 after cutting is greater than 2 microns and less than 4 microns, the first semi-finished product 1 is directly placed on a grinding machine for grinding the end face 018 to form a second semi-finished product 2; the thickness of the second semi-finished product 2 is H2; wherein, H1>H2>H.

[0060] Through the above steps, the parallelism of the two end faces 018 of the first semi-finished product 1 can be ensured, so that the subsequent processing of the suction hole 014, the slide groove 015, and the spring hole 020 is facilitated by taking the end face 018 as a reference.

[0061] like Fig.41 As shown, in S3, after the second semi-finished product 2 is formed, the longitudinal textures 013 of the plane surfaces 011 on both sides of the second semi-finished product 2 are opened with the end surface 018 of the second semi-finished product 2 as a reference.

[0062] S4: Fig.42 As shown, firstly, the second semi-finished product 2 is horizontally clamped, and the suction hole 014 is opened horizontally; after the suction hole 014 is opened, Fig.43 As shown, the second semi-finished product 2 is horizontally clamped again, and a spring hole 020 is opened transversely; like Fig.44 As shown, a plurality of second semi-finished products 2 are then stacked and clamped along the thickness direction, and longitudinally opened to form the slide grooves 015 and the connecting holes 022 .

[0063] In the above steps, the plurality of second semi-finished products 2 are first placed horizontally, that is, the plurality of second semi-finished products are placed on the same horizontal plane, so as to complete the transverse opening of the air suction hole 014, and the axis of the air suction hole 014 is consistent with the radial direction of the cylinder body; then the plurality of second semi-finished products 2 are horizontally adjusted and re-clamped to complete the transverse opening of the spring hole 020, and the axis of the spring hole 020 is consistent with the radial direction of the cylinder body; Subsequently, a plurality of second semi-finished products 2 are stacked, and then the vane groove 015 and the connecting hole 022 are longitudinally opened, wherein the axis of the vane groove 015 is consistent with the radial direction of the cylinder body, thereby forming a third semi-finished product 3.

[0064] S5: Fig.45 As shown, a plurality of third semi-finished products 3 having suction holes 014, slide grooves 015, spring holes 020 and connecting holes 022 after processing are clamped on a milling machine with a fixture, and after completion, rough milling and fine milling of the slide grooves 015 are performed in sequence; the finely milled third semi-finished products 3 are transferred to a grinding machine with a fixture, and fine grinding of the slide grooves 015 is performed, and after fine grinding is completed, a fourth semi-finished product 4 is formed.

[0065] In the above steps, since there is a sliding vane in the sliding vane slot 015 , in order to ensure the accuracy of the sliding vane movement, the sliding vane slot 015 needs to be roughly milled, finely milled, and finely ground to ensure the accuracy of the size of the sliding vane slot 015 .

[0066] S6: Fig.46 As shown, the fourth semi-finished product 4 is placed on a double-end surface grinder or a surface grinder, and both end surfaces of the fourth semi-finished product 4 are finely ground to form a fifth semi-finished product 5, and the thickness of the fifth semi-finished product 5 is H5; wherein, H1>H2>H5=H.

[0067] In the above steps, since the semi-finished product is clamped in S4 and S5, the two end faces 018 of the semi-finished product are bound to be scratched or clamped. In order to further ensure the parallelism of the two end faces 018, the two end faces of the fourth semi-finished product 4 are processed to form the fifth semi-finished product 5.

[0068] S7: Fig.47 As shown, the fifth semi-finished product 5 is placed on a grinding machine, and the outer arc surface 016 and the inner arc surface 017 of the fifth semi-finished product 5 are ground until the size of the outer arc surface 016 and the inner arc surface 017 of the fifth semi-finished product 5 is ground to be consistent with the size of the mosaic block finished product 01.

[0069] In the above steps, the outer arc surface 016 and the inner arc surface 017 of the fifth semi-finished product 5 are ground to form the mosaic block finished product 01, ensuring that the outer arc surface 016 of the mosaic block finished product 01 is coplanar with the outer side surface of the cylinder body, and the inner arc surface 017 of the mosaic block finished product 01 is coplanar with the inner side surface of the cylinder body, ensuring that the mosaic block finished product 01 does not protrude from the inner and outer walls of the cylinder body.
