Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1:

[0038] like Figures 1 to 7 As shown, Embodiment 1 of this utility model provides a cooling water circulation system for sheet metal precision machining machine tools, used to filter cooling water, remove waste residue from the cooling water, and enable the cooling water to be reused and recycled. The system includes a cylinder 1, with a water inlet pipe 2 welded to its top. A cylinder seat 3 is provided at the bottom of the inner cavity of the cylinder 1. A filter cylinder 4 is fixed to the top of the cylinder seat 3. The filter cylinder 4 is a metal mesh cylinder with densely packed filter holes for filtering metal waste from the cooling water. The top of the filter cylinder 4 is closed, and the bottom has a water outlet. A water outlet hole 5 is provided on the cylinder seat 3 corresponding to the position of the water outlet.

[0039] like Figure 5 As shown, a lead screw 7 and a guide rod 9 are rotatably mounted inside the cylinder 1. The lead screw 7 and guide rod 9 are parallel to the axis of the cylinder 1. The top end of the lead screw 7 extends out of the cylinder 1 and connects to the output shaft of the motor 8, which is fixed to the top of the cylinder 1. The connection between the lead screw 7 and the cylinder 1 is sealed by a first sealing ring 10. A slip ring 6 is threaded to the lead screw 7 and slidably fitted onto the guide rod 9. The bristles 11 on the inner wall of the slip ring 6 are made of nylon and their length is adapted to the mesh size of the filter cartridge 4, ensuring that they penetrate deep into the mesh to remove stubborn impurities during scraping.

[0040] In the initial state, motor 8 drives slip ring 6 to move upward, causing slip ring 6 to disengage from filter cartridge 4 and cartridge base 3. Cooling water is injected into the cartridge 1 from inlet pipe 2, passes through slip ring 6, is filtered by filter cartridge 4, and is discharged into coolant storage tank through outlet hole 5. When filter residue accumulates and causes a decrease in filtration effect, motor 8 reverses to cause slip ring 6 to move downward and fit onto filter cartridge 4. The bristles 11 on the inner wall of slip ring 6 simultaneously scrape off impurities from the surface of filter cartridge 4, and the filter residue is squeezed into the residue-containing cavity between cartridge base 3 and cartridge 1, compressing the filter residue and achieving the functions of self-cleaning of filter cartridge 4 and compressing filter residue.

[0041] Through the above arrangement, the utility model can filter the cooling water, intercept the metal scrap particles in it, so that the cooling water can be recycled; meanwhile, the self-cleaning mechanism of the filter cartridge 4 is designed, which effectively maintains the filtering efficiency of the filter cartridge 4.

[0042] Example two:

[0043] This embodiment further optimizes the structure and driving control of the slip ring 6 on the basis of example one. The slip ring 6 is composed of a base ring 61 and a movable ring 62, a limiting cylinder 64 is fixed on the movable ring 62, the base ring 61 is sleeved on the outer wall of the limiting cylinder 64 and is limited in axial displacement through a limiting screw 65, and a compression spring 63 is sleeved on the outside of the limiting cylinder 64 and is pre-compressed between the base ring 61 and the movable ring 62. The bristles 11 are fixed on the inner wall of the limiting cylinder 64. When the slip ring 6 moves downward to extrude the filter residue, the movable ring 62 compresses the compression spring 63 under the resistance of the filter residue, so as to avoid rigid impact; at the same time, the motor 8 adopts a stepping motor 8 and controls the rotating speed of the motor 8 through a PLC, so that the slip ring 6 presses the filter residue at a constant pressure, and the filter residue is ensured to be compacted.

[0044] As shown in Figure 5 and Figure 7 , the inside of the cylinder seat 3 is hollow, and a top rod 14 is inserted from the bottom of the cylinder seat 3. The cylinder seat 3 and the top rod 14 are connected through threads. The tapered part 15 at the top of the top rod 14 can cooperate with the necking part 16 on the cylinder seat 3 to tightly press the edge of the water outlet of the filter cartridge 4, so as to fix the filter cartridge 4. The top rod 14 and the tapered part 15 are provided with through water outlets 5. By tightening the top rod 14, the tapered part 15 and the necking part 16 form a seal, preventing unfiltered water from leaking. A third sealing ring 13 is arranged between the top rod 14 and the inner wall of the cylinder seat 3, preventing filtered cooling water from leaking from the threaded connection between the top rod 14 and the cylinder seat 3. The filtered cooling water of the filter cartridge 4 is discharged from the water outlets 5 on the tapered part 15 and the top rod 14.

[0045] Example three:

[0046] On the basis of example one and example two, the utility model proposes example three, and the filter residue cleaning and the maintainability of the cylinder seat 3 are improved in this example three. A through hole is formed in the bottom of the cylinder body 1, the outer wall of the cylinder seat 3 is processed with external threads and is screwed into the through hole after penetrating the second sealing ring 12, so as to realize quick sealing, disassembly and assembly. When the filter residue needs to be cleaned, the water inlet pipe 2 is closed and the cylinder seat 3 is disassembled, and the filter residue is taken out together with the cylinder seat 3, at this time, the filter cartridge 4 is also taken out.

[0047] The top rod 14 on the inner side of the cylinder seat 3 can be individually screwed out, so as to release the limiting of the filter cartridge 4, facilitating the replacement or cleaning of the filter cartridge 4.

[0048] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
