Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting processing, in particular to a water spray plate for anti-clogging wire cutting. Background Art

[0002] The wire cutting water spray plate is a component used in the cooling system of the wire cutting machine tool in the mechanical processing industry. The electrode wire passes through the wire threading hole of the water spray plate. During the cutting process of the machined parts, the cooling water continuously sprays the electrode wire to cool it. In the prior art, the cooling water outlet is often in the shape of a narrow ring, arranged around the electrode wire, in order to quickly spray and cool the electrode wire. However, in production practice, the water outlet is often blocked by debris generated by cutting. When the water outlet is blocked, the water outlet direction will be deflected and the electrode wire cannot be evenly and effectively cooled. Moreover, the narrow ring design of the water outlet is not conducive to providing a large water flow rate and improving the cooling performance. In addition, if the debris accumulates at the water outlet, the electrode wire will be cut, which will reduce the service life of the electrode wire. Utility Model Content

[0003] The utility model discloses an anti-clogging water spray plate for wire cutting, which solves the technical problems in the prior art that debris blocks the water outlet, reduces the cooling effect and service life of the electrode wire, and has a reasonable structure, good electrode wire cooling effect and is conducive to improving the service life of the electrode wire. The technical solution adopted is as follows:

[0004] A water spray plate for anti-clogging wire cutting includes a plate body and a water inlet pipeline. The plate body is provided with a first wire threading hole for an electrode wire to pass through. The first wire threading hole includes a first notch, which extends outward and forms a first wire inlet on the side wall of the plate body. An annular cavity arranged around the first wire threading hole is provided in the plate body. The annular cavity is connected to the water inlet pipeline, and the annular cavity is connected to the outside world upward through a first water outlet. There are multiple and independent first water outlets. The first water outlet is designed to face the axis of the first wire threading hole so that cooling water sprayed through the first water outlet can cool the electrode wire.

[0005] Based on the above technical solution, the plurality of first water outlets are evenly arranged in the circumferential direction.

[0006] On the basis of the above technical solution, the annular cavity is connected with the water inlet pipeline through a water flow pipeline in the plate body, and the water flow pipeline is coaxial with the water inlet pipeline and extends radially along the annular cavity.

[0007] Based on the above technical solution, a plurality of the first water outlets are symmetrically arranged on both sides of the water flow pipe.

[0008] On the basis of the above technical solution, the first water outlet is connected to the annular cavity through a guide section, and on the radial surface of the annular cavity, the channel formed by the guide section and the annular cavity is stepped to increase the cooling water spraying velocity.

[0009] Based on the above technical solution, the guide section is arranged close to the first threading hole, and the guide section is coplanar with the first inner wall surface of the annular cavity close to the first threading hole, and the first inner wall surface has an angle inclined toward the axis of the first threading hole along the water flow direction.

[0010] On the basis of the above technical solution, it also includes a protective cover, the first wire threading hole and the first water outlet extend outside the plate body and form a convex portion, the protective cover is detachably connected to the convex portion, the first wire threading hole extends on the protective cover to form a second wire threading hole, the first water outlet extends on the protective cover to form a second water outlet, the first notch extends on the protective cover to form a second notch connected to the second wire threading hole, and the second notch extends outward to form a second wire inlet on the side wall of the protective cover.

[0014] Beneficial Effects

[0015] The utility model has a reasonable structure. A plurality of first water outlets are arranged circumferentially outside the first threading hole. The plurality of first water outlets are independent and are all arranged toward the first threading hole. Compared with the existing narrow ring-shaped water outlet design, the first water outlet and the annular cavity in the utility model form a water outlet channel with a simpler internal structure, and the energy loss of cooling water in the water outlet channel is small. Under the premise of the same water inlet flow rate and water outlet flow rate, the water output per unit time in the present application is larger, that is, the caliber of the first water outlet is larger, and the cooling effect is better. In addition, the plurality of first water outlets are arranged circumferentially, and the sprayed water flow can offset each other at the axis of the first threading hole, and the cooling effect is good. The caliber of the first water outlet in the utility model is larger, and the water flow rate is larger, which reduces the probability of debris blocking the water outlet, and after blocking, it can be carried out by the water flow in time, which is conducive to reducing the failure rate and increasing the service life of the electrode wire.

[0016] The utility model also includes a protective cover, which is inserted on the convex part and is provided with a second threading hole, a second water outlet and a second wire inlet. In this way, when debris falls and blocks the aforementioned gaps, the shield can be easily removed and cleaned. The operation is convenient and is beneficial to improving the service life of the water spray plate. In addition, the inner wall surface of the second threading hole is arranged close to the electrode wire, wherein the gap size between the inner wall surface of the second threading hole and the electrode wire can be set to be smaller than the particle size of most debris. On the one hand, it can prevent debris from getting stuck in the second threading hole, and on the other hand, it can make most of the cooling water flow from the inside to the outside after being sprayed out, thereby carrying away the debris and the like, which is beneficial to maintaining the cleanliness of the second threading hole and improving the service life of the electrode wire.

[0017] In the utility model, the plugging block is detachably connected to the plate body, and even when debris enters the annular cavity through the second water outlet and the first water outlet, it can be conveniently removed for cleaning, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 3The anti-clogging water spray plate for wire cutting shown in the figure comprises a plate body 1, 3 water inlet pipes and a plug block 2.

[0029] like Figure 3 and 4 As shown, the plate body 1 is provided with an axial hole, the plug 2 is upwardly embedded in the axial hole on the plate body 1, the first wire threading hole 11 passes through the plug 2 for the electrode wire to pass through, and the first wire threading hole 11 includes a first notch, the first notch extends outward and forms a first wire inlet 13 on the side wall of the plate body 1, and another notch is formed on the plug 2, so that the electrode wire can enter the first wire threading hole 11 from outside the plate body 13. In other embodiments of the utility model, the plug 2 and the plate body 1 can adopt other forms of detachable connection.

[0030] like Figure 2 and 3 As shown, the plug block 2 and the plate body 1 are jointly enclosed to form an annular cavity 100 and three first water outlets 14. The annular cavity 100 is arranged around the first threading hole 11. The annular cavity 100 is connected to the water inlet pipe 3, and the annular cavity 100 is connected to the outside through the first water outlet 14 upward. The three first water outlets 14 are independent of each other and are evenly arranged circumferentially. The first water outlet 14 is designed to face the axis of the first threading hole 11 so that the cooling water sprayed through the first water outlet 11 converges and cools the electrode wire. Specifically, the first water outlet 14 is connected to the annular cavity 100 through the guide section, and on the radial surface of the annular cavity 100, as shown Figure 2 As shown, the channel formed by the guide section and the annular cavity 100 is stepped to increase the cooling water spray velocity; in addition, the guide section is arranged close to the first threading hole 11, and the guide section and the first inner wall surface of the annular cavity 100 close to the first threading hole 11 are coplanar, and the first inner wall surface has an angle inclined toward the axis of the first threading hole 11 along the water flow direction. This greatly simplifies the water outlet channel structure formed by the first water outlet 14 and the annular cavity 100, reduces the energy loss of cooling water in the water outlet channel, and on the other hand, the design of the water outlet channel that is wide at first and narrow at the end effectively ensures the flow velocity of the cooling water when it is sprayed out. On the other hand, the design of the guide section can effectively guide the water flow, so that the cooling water can be sprayed out at a set angle.

[0031] like Figure 2 As shown, the annular cavity 100 is connected with the water inlet pipe 3 through the water flow pipe 200 in the plate body 1. The water flow pipe 200 is coaxial with the water inlet pipe 3 and extends radially along the annular cavity 100. In addition, three first water outlets 14 are symmetrically arranged on both sides of the water flow pipe 200. Specifically, the axis of one first water outlet 14 intersects with the axis of the water flow pipe 200, and the other two first water outlets 14 are symmetrically arranged. In this way, it can be ensured that the cooling water in the annular cavity 100 flows roughly symmetrically, and the cooling water sprayed through multiple first water outlets 14 can be roughly symmetrically arranged on both sides of the electrode wire, which is beneficial to improve the cooling uniformity.

[0032] like Figure 4 As shown, the first wire threading hole 11 and the first water outlet 14 extend to the outside of the plate body 1 and form a convex portion, and the shield 4 is detachably connected to the convex portion. In this embodiment, the shield 4 is plugged into the convex portion and has an interference fit. The first wire threading hole 11 extends on the shield to form a second wire threading hole 41, and the first water outlet 14 extends on the shield to form a second water outlet 44. The first notch extends on the shield to form a second notch connected to the second wire threading hole 41, and the second notch extends outward and forms a second wire inlet 43 on the side wall of the shield 4 to facilitate the electrode wire to enter the second wire threading hole 41.

[0033] like Figure 1 As shown, the second threading hole 41 is in the shape of a slit, and the inner wall surface is arranged close to the electrode wire. In this embodiment, the gap size between the inner wall surface of the second threading hole 41 and the electrode wire can be set to be smaller than the particle size of most debris. On the one hand, it can prevent debris from getting stuck in the second threading hole 41, and on the other hand, it can allow most cooling water to flow from the inside to the outside after being sprayed out, thereby carrying away the debris, etc., which is beneficial to maintaining the cleanliness of the second threading hole 41 and improving the service life of the electrode wire.

[0034] like Figure 1 As shown, two long positioning holes 101 are provided on the plate body 1, and the long positioning holes 101 pass through the plate body 1 and are symmetrically arranged on both sides of the first threading hole 11, so as to facilitate the positioning of the plate body 1. A magnetic block (not shown) is also embedded on the plate body 1 to assist in positioning the plate body 1.

[0035] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
