Description

Technical Field

[0001] The utility model relates to the technical field of cutting tooling, and particularly relates to a cutting auxiliary tooling. Background Art

[0002] In the existing cutting processes, cutting tools manufactured based on different working principles can all achieve the purpose of cutting. For example, laser cutting, flame cutting, wire cutting, ultra-high pressure water cutting, plasma cutting, etc. However, in the actual operation process, it is very difficult to ensure the stability of the cutting tool during cutting.

[0003] Taking the plasma cutting gun as an example for specific illustration, plasma cutting guns have multiple characteristics and advantages, such as high speed, smooth cutting surface, and small thermal deformation, which makes them widely used in the field of metal processing. In actual operation, key factors affecting the cutting effect include selecting the appropriate working gas, adjusting the distance between the torch and the workpiece, cutting speed, and thickness selection. For occasions with not particularly high precision requirements and cost-sensitive users, the plasma cutting gun becomes the preferred choice. In the actual construction process, although the plasma cutting gun can achieve a certain degree of automated operation, the degree is very limited and still requires manual participation. However, during the process of manual participation in construction, it is very difficult to avoid the situation where the construction personnel's hands shake, resulting in unstable plasma gas flow ejected by the plasma cutting gun or deviation from the preset trajectory, thus forming uneven cuts at the cutting position of the workpiece, or even over-cutting or under-cutting phenomena. Content of the Utility Model

[0004] In view of the above problems existing in the prior art, the utility model provides a cutting auxiliary tooling.

[0005] The utility model provides a cutting auxiliary tooling, which includes an independent profiling part and a stabilizing component. The profiling part includes a fitting part and an abutting part that defines the distance between the nozzle of the cutting tool and the workpiece to be cut. The fitting part is close to the edge of the stabilizing component to define the walking trajectory of the cutting tool during cutting. The stabilizing component includes a walking stabilizing piece and a positioning piece fixedly connected to it for fixing the cutting tool. One side of the walking stabilizing piece close to the workpiece to be cut can be attached to the side of the fitting part away from the abutting part. The length of the part of the positioning piece between the walking stabilizing piece and the workpiece to be cut is not greater than the vertical distance between the side of the abutting part close to the workpiece to be cut and the side of the fitting part away from the abutting part.

[0009] Furthermore, the walking stabilizing member is fan-shaped.

[0010] Furthermore, the positioning member is a hollow cylinder.

[0011] Furthermore, a gas passage for the flow of the gas required for the jet of the cutting tool is provided at one end of the cylinder close to the workpiece to be cut.

[0012] Furthermore, one end of the cylinder close to the workpiece to be cut is in a rack shape, and the gas passage is the gap formed between adjacent racks.

[0013] Furthermore, the profiling member further includes a magnet located between the fitting portion and the workpiece to be cut, and the magnet is used to fix the profiling member on the workpiece to be cut.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the present utility model.

[0024] The cutting auxiliary tooling provided by the present utility model can be used in combination with different types of cutting tools, such as laser cutting tools, flame cutting tools, wire cutting tools, ultra-high pressure water cutting tools, plasma cutting tools, etc. For the sake of convenience of description and understanding, as Figures 1 - 3As shown in the figure, in the description part of the present utility model, taking the plasma cutting gun as an example for the cutting tool, the cutting auxiliary tooling provided in this embodiment includes an independent profiling part and a stabilizing component. The profiling part includes two parts, a fitting part 1 and an abutting part 2. The function of the abutting part 2 is to define the distance between the nozzle of the plasma cutting gun and the workpiece to be cut. The edge of the fitting part 1 close to the stabilizing component is used to define the walking trajectory when the plasma cutting gun cuts. The stabilizing component includes two components, a walking stabilizing piece 3 and a positioning piece 4. The walking stabilizing piece 3 is fixedly connected to the positioning piece 4. The function of the positioning piece is to fix the plasma cutting gun. The length of the part of the positioning piece 4 between the walking stabilizing piece 3 and the workpiece to be cut is slightly less than the vertical distance between the side of the abutting part 2 close to the workpiece to be cut and the side of the fitting part 1 away from the abutting part 2. When in use, the side of the walking stabilizing piece 3 close to the workpiece to be cut is fitted with the side of the fitting part 1 away from the abutting part 2.

[0025] For the cutting auxiliary tooling provided by the present utility model, the gun head of the plasma cutting gun is fixed by the positioning piece 4 of the stabilizing component, thereby fixing the plasma cutting gun. The abutting part 2 of the profiling part is abutted on the surface of the workpiece to be cut. The abutting part 2 of the profiling part is used to define the distance between the nozzle of the plasma cutting gun and the workpiece to be cut. When cutting the workpiece, the side of the walking stabilizing piece 3 of the stabilizing component close to the workpiece to be cut is fitted with the side of the fitting part 1 of the profiling part away from the abutting part 2, and the side of the positioning piece 4 of the stabilizing component close to the walking stabilizing piece 3 is abutted on the lower edge of the fitting part 1 of the profiling part. The user holds the plasma cutting gun fixed on the stabilizing component and walks along the lower edge of the fitting part 1 of the profiling part, and then a workpiece cut with a preset shape can be formed.

[0026] Due to the design of the abutting part 2 of the profiling part, it ensures that the distance between the nozzle of the plasma cutting gun and the workpiece to be cut is a fixed value, avoiding phenomena such as unstable plasma gas flow ejected by the plasma cutting gun, uneven workpiece cut, or even over-cutting or under-cutting caused by factors such as the user's hand shaking, which enhances the stability of the plasma cutting gun during cutting; since the plasma cutting gun is fixed on the positioning piece 4 of the stabilizing component, the edge of the fitting part 1 of the profiling part close to the stabilizing component is used to define the walking trajectory when the plasma cutting gun cuts the workpiece to be cut. By different designs of the edge of the fitting part 1 of the profiling part, preset workpiece cuts such as line segments, arcs, and required geometric figures can be cut.

[0027] In this embodiment, both the fitting part 1 and the abutting part 2 of the profiling part are long strip steel plates with uniform thickness. The fitting part 1 and the abutting part 2 are perpendicularly distributed. The cross-section of the whole profiling part is a T-shape. The cross-section of the abutting part 2 is the vertical part of the T-shape, and the cross-section of the fitting part is the horizontal part of the T-shape. The cross-section of the edge of the fitting part 1 close to the stabilizing component is one end of the horizontal part of the T-shape.

[0028] The T-shaped design reduces the use of materials as much as possible while ensuring the function of the profiling part, thereby reducing the manufacturing cost. The surface on the side of the abutting part 2 away from the fitting part 1 is flat. When the profiling part abuts against the surface of the workpiece to be cut, the abutting part 2 is perpendicular to the surface of the workpiece to be cut. At this time, the abutting part 2 is in line contact with the surface of the workpiece to be cut. The edge of the fitting part 1 of the profiling part close to the stabilizing component is a line segment. The user holds the plasma cutting gun fixed to the stabilizing component and walks along the lower edge of the fitting part 1 of the profiling part, and a workpiece incision in the shape of a line segment can be cut.

[0029] In a specific embodiment, the side of the abutting part 2 away from the fitting part 1 can be a flat surface, so that the abutting part 2 and the workpiece to be cut can achieve surface contact, increasing the contact area between the abutting part 2 and the workpiece to be cut. Under the same pressure, the friction between the abutting part 2 and the workpiece to be cut is increased, preventing the relative movement of the abutting part 2 relative to the workpiece to be cut during construction. The side of the abutting part 2 away from the fitting part 1 can also be serrated, so that multiple point contacts can be achieved between the abutting part 2 and the workpiece. The abutting part 2 and the fitting part 1 of the profiling part can be of any shape that meets its functional conditions.

[0030] In a specific embodiment, the edge of the fitting part 1 of the profiling part close to the stabilizing component is an arc. The user holds the plasma cutting gun and walks along the lower edge of the fitting part 1 of the profiling part, and a workpiece incision in the shape of an arc can be cut. When the profiling part is an annular structure, the inner edge of the annulus forms a closed geometric figure. The user holds the plasma cutting gun and walks along the lower edge of the fitting part 1 of the profiling part, and a workpiece incision in the shape of the geometric figure can be cut. According to specific needs, the edge of the fitting part 1 of the profiling part can be designed differently. Of course, different profiling parts with different edges of the fitting part 1 can also be used in combination to meet the requirement of the shape of the workpiece incision formed by the combination of line segments, arcs, and geometric figures.

[0031] In this embodiment, the walking stabilizer 3 and the positioning member 4 that constitute the stabilizing assembly are detachably connected, specifically by plugging. This setting enables the walking stabilizer 3 and the positioning member 4 to be designed and produced independently of each other, simplifying the manufacturing process. The walking stabilizer 3 and the positioning member 4 are perpendicular to each other. At this time, the cut surface at the incision of the workpiece is perpendicular to the surface of the workpiece to be cut. The shape of the walking stabilizer 3 is fan-shaped. One advantage of this setting is that while ensuring the function of the walking stabilizer 3, the use of materials can be minimized as much as possible, thereby reducing the manufacturing cost. When the middle of the fan shape is a hollow design, the use of materials can be further reduced, and thus the manufacturing cost can be further reduced. Another advantage is that when the fitting portion 1 of the profiling member has a corner, the positioning member 4 fixed with the plasma cutting gun walks on one side edge of the corner of the fitting portion 1 of the profiling member, and the center line of the plasma cutting gun head will increase the maximum distance from the other side edge of the corner. In this scenario, the fan shape well ensures that there is sufficient fitting area between the side of the walking stabilizer 3 close to the workpiece to be cut and the side of the fitting portion 1 of the profiling member away from the abutting portion 2, thereby ensuring the stability of the plasma cutting gun during cutting.

[0032] In a specific implementation manner, the walking stabilizer 3 and the positioning member 4 that constitute the stabilizing assembly can be an integral structure. In some specific scenarios, it is required that the cut at the incision of the workpiece is not perpendicular to the surface of the workpiece, but forms an inclined angle. At this time, it can be achieved by forming a certain angle between the walking stabilizer 3 and the positioning member 4, or by changing the structure of the fitting portion 1 of the profiling member. Specifically, the structure of the fitting portion 1 can be changed to make its thickness uneven along the length direction or uneven along its width direction.

[0033] In this embodiment, the positioning member 4 is in the shape of a hollow cylinder. The length of the cylindrical part of the positioning member 4 located between the walking stabilizer 3 and the workpiece to be cut is slightly less than the vertical distance between the side of the abutting portion 2 close to the workpiece and the side of the fitting portion 1 away from the abutting portion 2, so as to avoid affecting the function of the abutting portion 2 of the profiling member in limiting the distance between the nozzle of the plasma cutting gun and the workpiece. If the length of the cylindrical part of the positioning member 4 located between the walking stabilizer 3 and the workpiece to be cut is equal to the vertical distance between the side of the abutting portion 2 close to the workpiece and the side of the fitting portion 1 away from the abutting portion 2, the frictional resistance between the positioning member 4 and the workpiece to be cut will increase; if the length of the cylindrical part of the positioning member 4 located between the walking stabilizer 3 and the workpiece to be cut is greater than the vertical distance between the side of the abutting portion 2 close to the workpiece and the side of the fitting portion 1 away from the abutting portion 2, the abutting portion 2 of the profiling member cannot play the role of limiting the distance between the nozzle of the plasma cutting gun and the workpiece.

[0034] In a specific embodiment, the positioning member 4 can be in the shape of a semi-cylindrical shape or multiple circular rings. The shapes of the positioning member 4 are too numerous to list exhaustively. The positioning member 4 can even be several thin strings or wires; it can be a clamping member with various shapes. In short, on the one hand, the positioning member 4 has the function of fixing the tip of the plasma cutting gun, and on the other hand, it has the function of cooperating with the walking stabilizing member 3 for common use.

[0035] In this embodiment, a plurality of through holes are provided in the side wall of the cylinder, and the same number of screws as the through holes pass through the through holes to further fix the positioning member 4 and the plasma cutting gun. One end of the positioning member 4 away from the walking stabilizing member 3 is in the shape of a rack, and the gaps formed between adjacent racks constitute the gas channels required for the plasma gas flow ejected by the plasma cutting gun to flow.

[0036] The design of the cylindrical shape can increase the contact area between the positioning member 4 and the plasma cutting gun, increase the stability of the positioning member 4 in fixing the plasma cutting gun, and the use of multiple screws can further enhance this stability. The rack-shaped design can enable the plasma gas flow ejected by the plasma cutting gun to flow smoothly, preventing the pressure of the plasma cutting gun from being insufficient due to backfire, and thus avoiding the bad phenomenon of the workpiece not being cut off.

[0037] In a specific embodiment, the gas channels required for the plasma gas flow ejected by the plasma cutting gun to flow can also be a plurality of strip-shaped holes.

[0038] In a specific embodiment, the profiling member further includes a magnet. During use, the magnet is placed between the fitting portion 1 and the workpiece to be cut, and the profiling member is firmly fixed on the workpiece to be cut, preventing the profiling member from moving relative to the workpiece to be cut during construction.

[0039] In this embodiment, the side of the walking stabilizing member 3 close to the workpiece to be cut and the side of the fitting portion 1 away from the abutting portion 2 are both flat surfaces. This design simplifies the manufacturing process and reduces the production cost. In a specific embodiment, the side of the walking stabilizing member 3 close to the workpiece to be cut and the side of the fitting portion 1 away from the abutting portion 2 only need to be able to achieve fitting. For example, the side of the walking stabilizing member 3 close to the workpiece to be cut can be provided with a groove, and the side of the fitting portion 1 away from the abutting portion 2 is provided with a convex block of a matching size.
