Description

Technical Field

[0001] The utility model relates to the field of cutting ceramic shell fragments, in particular to a cutting knife used for ceramic shell fragments. Background Art

[0002] The existing method for preparing the ceramic shell is to cut and sinter the cast sheet and then split it. The cast sheet is a flat extruded film or sheet produced by a melt slugging and quenching process, and has good tensile strength.

[0003] In the prior art, the cutter used in the above-mentioned cast sheet cutting process usually only includes a cutter body and a blade, and the angle of the blade tip is about 9 degrees. The incision of this cutter during the cutting process is small, which easily causes the cast sheet to be not completely divided. After cutting, due to pressure, the cut incision heals inward, and during the sintering process of the cast sheet, the cast sheet will expand, so that the two sides of the cut are connected, which makes the ceramic shell unable to split, or forms irregular sides after splitting. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cutter for ceramic shell cracks to prevent the cast sheet from healing inwards after being cut.

[0005] The utility model is implemented as follows: a cutter for ceramic shell splits, comprising a cutter body and a blade, wherein the blade is connected to one end of the cutter body;

[0006] The blade includes a blade tip and a first anti-healing member;

[0007] The blade tip is connected to the first anti-healing component, and the first anti-healing component is connected to the blade body;

[0008] The angle of the blade tip is A, and A is 25° to 35°;

[0009] The first anti-healing component is a structure that protrudes outward in the middle and narrows inward at both ends.

[0010] Furthermore, the blade further comprises at least one second anti-healing member located above the first anti-healing member and connected to the first anti-healing member;

[0011] The middle length of the first anti-healing piece is L1, and the middle length of the second anti-healing piece is L2. The middle length L1 of the first anti-healing piece is greater than the middle length L2 of the second anti-healing piece.

[0012] Furthermore, the blade body includes at least two fixing holes.

[0013] The advantages of the utility model are: compared with the prior art, the utility model has a larger incision when cutting, and an anti-healing part helps to maintain the incision when cutting the cast sheet, preventing the cast sheet from healing inward again after cutting, and finally makes it easier to split the sintered ceramic shell, and there is no burr on the edge of the ceramic shell after splitting. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0015] Figure 1 It is an overall schematic diagram of the utility model.

[0016] Figure 2 It is an enlarged schematic diagram of the blade of the utility model. DETAILED DESCRIPTION

[0017] The utility model provides a cutter for ceramic shell cracks, thereby solving the problem in the prior art that the cut of the cast sheet will heal after the cast sheet is split.

[0018] See also Figure 1 and Figure 2 As shown, the utility model provides a cutter for ceramic shell splitting, comprising a cutter body 1 and a blade 2, wherein the blade 2 is connected to one end of the cutter body 1;

[0019] The blade 2 includes a blade tip 21 and a first anti-healing member 22, wherein the blade tip 21 is used for cutting, and the first anti-healing member 22 is used for maintaining the incision and preventing healing;

[0020] The blade tip 21 is connected to the first anti-healing component 22, and the first anti-healing component 22 is connected to the blade body 1;

[0021] The angle of the blade tip 21 is A, and A is 25° to 35°, which is used to make a larger incision;

[0022] The angle A of the blade tip 21 is preferably 30° in this embodiment;

[0023] The first anti-healing member 22 is as follows: Figure 2 As shown in the figure, it is a structure that bulges outward in the middle and narrows inward at both ends. It is used for repeated cutting of incisions, maintaining incisions, and preventing healing.

[0024] In this embodiment, preferably, the blade 2 further includes at least one second anti-healing member 23 located above the first anti-healing member 22 and connected to the first anti-healing member 22, wherein the second anti-healing member 23 is Figure 2 As shown in , the structure is the same as the first anti-healing member 22;

[0025] The middle length of the first anti-healing piece 22 is L1, and the middle length of the second anti-healing piece 23 is L2. The middle length L1 of the first anti-healing piece 22 is greater than the middle length L2 of the second anti-healing piece 23.

[0026] In this embodiment, preferably, the cutter body 1 includes at least two fixing holes 3 to facilitate fixing the cutter on the machine.

[0027] In this embodiment, the blade body 1 is fixed to the machine through the fixing hole 3, and the cast sheet to be incised is placed thereon. The machine controls the blade body 1 to cut downward according to the set incision depth, and the blade 2 cuts the cast sheet through the blade tip 21. The first anti-healing member 22 passes through the cast sheet to make an incision, and the second anti-healing member 23 passes through the cast sheet to maintain the incision. When the blade 2 is withdrawn, the first anti-healing member 22 and the second anti-healing member 23 will pass through the incision of the cast sheet again to prevent the cast sheet from healing inward again after cutting.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
