Description

Technical Field

[0001] This utility model belongs to the technical field of wire cutting equipment, specifically an anti-fogging guide wheel. Background Technology

[0002] Wire EDM equipment typically requires guide rollers to guide the electrode wire and change its direction. During wire EDM, cutting fluid is also needed for cooling, and the electrode wire carries the cutting fluid onto the guide rollers as it works.

[0003] In practical work, when the guide wheel rotates at a high speed, the cutting fluid attached to the electrode wire will be atomized by the high-speed centrifugation of the guide wheel. The existing technology addresses the direction of the cutting fluid on the guide wheel by waterproofing the guide wheel to prevent the cutting fluid from entering the guide wheel mounting base, but does not control the atomization and diffusion of the cutting fluid. Utility Model Content

[0004] Purpose of the utility model: To provide an anti-fogging guide wheel, which, through the cooperation of the anti-fogging jacket and the guide wheel, allows the cutting fluid on the guide wheel to be splashed onto the anti-fogging jacket, reducing the atomization and diffusion of the cutting fluid, thus solving the problem that the existing guide wheels do not control the atomization and diffusion of the cutting fluid.

[0005] The technical solution of this utility model is as follows: an anti-fogging guide wheel includes: a bearing seat, a guide wheel, and an anti-fogging outer sleeve.

[0006] The guide wheel and the anti-fogging sleeve are mounted on the bearing housing. The anti-fogging sleeve is fitted onto the guide wheel to allow the cutting fluid on the guide wheel to splash onto the anti-fogging sleeve.

[0007] In a further embodiment, the guide wheel includes two sidewall portions.

[0008] The two sidewall portions are frustum-shaped structures with an outer diameter at the proximal end smaller than that at the distal end.

[0009] The anti-fogging jacket intersects with the extension lines of the busbars of the two side walls, allowing the cutting fluid to splash onto the anti-fogging jacket along the side walls.

[0010] In a further embodiment, the guide wheel further includes a raised ring, the outer diameter of which is larger than the outer diameter of the sidewall portion.

[0011] The protruding ring is perpendicular to the central axis of the side wall on one side, so that the cutting fluid splashes onto the inner wall of the anti-fogging jacket in a direction perpendicular to the central axis of the side wall, allowing the cutting fluid to accumulate on the inner wall of the anti-fogging jacket.

[0012] In a further embodiment, the raised ring is disposed on the side wall near the side of the anti-fogging sleeve installed on the bearing housing.

[0013] In a further embodiment, the anti-fogging jacket is provided with a clearance cavity, through which the electrode wire passes and connects with the guide wheel.

[0014] In a further embodiment, the guide wheel further includes a guide groove disposed between two sidewall portions.

[0015] The width of the clearance cavity is greater than the width of the guide groove.

[0016] In a further embodiment, the distance between the two sidewalls of the avoidance cavity and the two sidewalls of the guide groove is equal, reducing the probability of contact between the electrode wire and the avoidance cavity.

[0017] In a further embodiment, the anti-fogging jacket has an annular inner wall, which causes the cutting fluid on the guide wheel to splash onto the annular inner wall, and the cutting fluid on the annular inner wall to collect downwards along the annular inner wall.

[0018] In a further embodiment, the anti-fogging guide wheel includes: a bearing housing, the guide wheel having a rotating shaft mounted on the bearing housing.

[0019] In a further embodiment, the anti-fogging guide wheel includes: two bearing seats, the guide wheel is provided with two rotating shafts, the rotating shafts are mounted on the bearing seats, and at least one of the bearing seats is fitted with an anti-fogging sleeve.

[0020] The beneficial effects of this utility model are: by fitting the anti-fogging jacket onto the guide wheel, the cutting fluid on the guide wheel is splashed onto the anti-fogging jacket and collected, reducing the situation of atomization and spreading, and solving the problem that the guide wheel in the prior art does not control the atomization and spreading of cutting fluid.

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] This application discloses an anti-fogging guide wheel, which can be installed on the lower wire frame of a wire EDM machine. Through the cooperation between the anti-fogging jacket and the guide wheel, the cutting fluid on the guide wheel is splashed onto the anti-fogging jacket, reducing the atomization and diffusion of the cutting fluid. This solves the problem that the guide wheels in the prior art do not control the atomization and diffusion of the cutting fluid.

[0027] like Figure 1 and 3 The anti-fogging guide wheel 2 shown includes: a bearing housing 1, a guide wheel 2, and an anti-fogging outer sleeve 3.

[0028] The guide wheel 2 and the anti-fogging sleeve 3 are installed on the bearing housing 1. The anti-fogging sleeve 3 is fitted onto the guide wheel 2 and is used to allow the cutting fluid on the guide wheel 2 to splash onto the anti-fogging sleeve 3. The anti-fogging sleeve 3 has an end face, and an annular inner wall fitted onto the guide wheel 2 extends from the end face in the direction of the guide wheel 2. The cutting fluid can splash onto the annular inner wall of the anti-fogging sleeve 3 or onto the end face of the anti-fogging sleeve 3.

[0029] like Figure 2 The guide wheel 2 shown includes two sidewall portions 21.

[0030] The two sidewall portions 21 are conical structures with an outer diameter at the near end smaller than that at the far end.

[0031] The anti-fogging jacket 3 intersects with the extension lines of the generatrix of the two side wall portions 21. The generatrix refers to the generatrix that rotates around the central axis of the guide wheel 2 to form the conical structure surface of the side wall portion 21. The anti-fogging jacket 3 can be extended to make it intersect with the extension lines of the generatrix of the two side wall portions 21.

[0032] like Figure 2 The guide wheel 2 shown also includes a raised ring 22, the outer diameter of which is larger than the outer diameter of the side wall portion 21.

[0033] The raised ring 22 is perpendicular to the central axis of the side wall portion 21 on the side near the side wall portion 21, so that the cutting fluid splashes onto the inner wall of the anti-fogging jacket 3 in a direction perpendicular to the central axis of the side wall portion 21.

[0034] like Figure 2 The raised ring 22 shown is disposed on the side wall portion 21 near the anti-fogging sleeve 3 and installed on one side of the bearing housing 1.

[0035] like Figure 1The anti-fogging jacket 3 shown has a clearance cavity 31, through which the electrode wire passes to connect with the guide wheel 2, as shown. Figure 1 The avoidance cavity 31 shown is not a complete annular groove. The anti-fogging jacket 3 is provided with a connecting part to connect the two ends of the anti-fogging jacket 3. The shape, size and position of the connecting part can avoid the electrode wire. The electrode wire can be a copper wire or a molybdenum wire.

[0036] like Figure 2 The guide wheel 2 shown also includes a guide groove 23, and the width of the clearance cavity 31 is greater than the width of the guide groove 23.

[0037] like Figure 2 The distance between the two side walls of the avoidance cavity 31 and the two side walls of the guide groove 23 is equal.

[0038] like Figure 1 The anti-fogging jacket 3 shown has an annular inner wall 32, which allows the cutting fluid on the guide wheel 2 to splash onto the annular inner wall 32.

[0039] like Figure 1 The anti-fogging guide wheel 2 shown includes: a bearing housing 1, and the guide wheel 2 is provided with a rotating shaft, which is mounted on the bearing housing 1, as shown below. Figure 2 The bearing housing 1 shown has two bearings, the shaft is mounted on the bearings, and the atomizing sleeve has a threaded hole so that the atomizing sleeve can be installed on the bearing housing 1 by tightening screws.

[0040] like Figure 3 The anti-fogging guide wheel 2 shown includes: two bearing seats 1, the guide wheel 2 is provided with two rotating shafts, the rotating shafts are installed on the bearing seats 1, and at least one bearing seat 1 is equipped with an anti-fogging sleeve 3. When one bearing seat 1 is equipped with an anti-fogging sleeve 3, the anti-fogging sleeve 3 forms a clearance cavity 31 by slotting on the anti-fogging sleeve 3. When both bearing seats 1 are equipped with anti-fogging sleeves 3, the clearance cavity 31 can be formed by adjusting the spacing between the anti-fogging sleeves 3.

[0041] Instructions for use: Pass the electrode wire through the clearance cavity 31 and connect it with the guide wheel 2, then extend the electrode wire from the clearance cavity 31 to the lower wire frame.

[0042] The wire cutting device drives the electrode wire to move, and the electrode wire drives the guide wheel 2 to rotate. During the movement of the electrode wire, the cutting fluid is carried to the guide groove 23 and the side wall 21.

[0043] The rotation of the guide wheel 2 causes the cutting fluid on the guide wheel 2 to splash onto the anti-fogging jacket 3 along the extension direction of the side wall portion 21.

[0044] When the side wall portion 21 is provided with a raised ring 22, the cutting fluid on the side of the raised ring 22 near the side wall portion 21 splashes onto the inner wall of the anti-fogging jacket 3 in a direction perpendicular to the central axis of the side wall portion 21.

[0045] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
