Description

Technical Field

[0001] The utility model belongs to the technical field of pipe cutting and clamping devices, in particular to a pipe cutting and clamping device for preventing welded pipes from being deformed. Background Art

[0002] In a welded pipe production line, the pipe cutting fixture plays a crucial role when cutting pipes to precise lengths. It not only securely holds the pipe, but also ensures that it remains stable throughout the cutting process, preventing any unnecessary movement or shaking. This is a prerequisite for high-quality cutting.

[0003] However, the current problems such as uneven clamping force, unreasonable clamping point selection or wear of the clamp itself can easily lead to the uneven extrusion force on the welded pipe mouth during the circular saw cutting process, causing deformation, and then forming an elliptical shape, which seriously affects the appearance quality and dimensional accuracy of the product. This defect will not only increase the subsequent repair process of the pipe mouth and reduce the overall efficiency of the production line, but also significantly increase production costs due to material waste and labor costs during the repair process. Utility Model Content

[0004] The purpose of the utility model is to solve the current problems of uneven clamping force, unreasonable clamping point selection or wear of the clamp itself, which easily lead to the uneven extrusion force on the welded pipe mouth during the circular saw cutting process, resulting in deformation, and then forming an elliptical deviation, which seriously affects the appearance quality and dimensional accuracy of the product. This defect not only increases the subsequent repair process of the pipe mouth and reduces the overall efficiency of the production line, but also significantly increases the production cost due to material waste and labor costs in the repair process. A pipe cutting and clamping device is proposed to prevent the deformation of the welded pipe.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a pipe cutting and clamping device for preventing welded pipe deformation, comprising:

[0006] First clamp body;

[0007] and a second clamping body;

[0008] A groove is provided in each of the first clamp body and the second clamp body, and a plurality of conical protrusions are provided on the groove. A cutting groove and a fixing hole are provided on each of the first clamp body and the second clamp body.

[0009] As a further description of the above technical solution:

[0010] The groove is in an arc shape.

[0011] As a further description of the above technical solution:

[0012] The cross section of the conical raised band is narrow outside and wide inside, and the adjacent conical raised bands are surrounded to form a hammer-shaped groove that is narrow inside and wide outside.

[0013] As a further description of the above technical solution:

[0014] The cutting groove on the first clamp body or the second clamp body extends from one outer wall thereof to one side of the groove.

[0015] As a further description of the above technical solution:

[0016] Clamping surfaces are provided on both sides of the cutting groove.

[0017] As a further description of the above technical solution:

[0018] The fixing member passes through the fixing holes on the first clamp body and the second clamp body in sequence.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] In the utility model, grooves are provided inside the first clamp body and the second clamp body, and conical raised bands are provided on the surface of the grooves. Conical holes are formed between the plurality of conical raised bands, so that when the first clamp body and the second clamp body are fixed by the fixing piece, they have better clamping force and wrapping effect on the pipe mouth, thereby avoiding the deformation of the pipe mouth caused by loosening of the welded pipe due to insufficient clamping force. The arc groove is added to the clamp so that when the clamp is clamped, the cutting pressure of the cutting saw can be dispersed and released when the clamp is clamped, so that the tolerance deformation of the pipe mouth is relatively small, and the pipe mouth after cutting is guaranteed to meet the tolerance requirements, thereby improving production quality and production efficiency.

[0033] See also Figure 1-3 The utility model provides a technical solution: a pipe cutting and clamping device for preventing welded pipe deformation, comprising:

[0034] First clamp body 1;

[0035] and a second clamp body 2;

[0036] A groove 3 is provided in each of the first clamp body 1 and the second clamp body 2 . A plurality of conical raised bands 4 are provided on each of the grooves 3 . A cutting groove 5 and a fixing hole 6 are provided on each of the first clamp body 1 and the second clamp body 2 .

[0037] The groove 3 is in an arc shape.

[0038] The cross section of the conical raised band is narrow outside and wide inside, and the adjacent conical raised bands 4 are surrounded to form hammer-shaped grooves 7 that are narrow inside and wide outside.

[0039] The cutting groove 5 on the first clamp body 1 or the second clamp body 2 extends from one outer wall thereof to one side of the groove 3 .

[0041] The fixing member passes through the fixing holes 6 on the first clamp body 1 and the second clamp body 2 in sequence.

[0042] Working principle: The internal grooves of the first clamping body and the second clamping body not only deepen the clamping depth of the clamp, but also provide orderly arranged conical raised belts on their surface. These conical raised belts are spaced from each other and together constitute a series of conical holes, forming a unique clamping interface. When the first clamping body and the second clamping body are tightly locked by high-strength fixing parts, the hammer-shaped protrusions in the conical holes form a precise interlocking relationship with the edge of the welded pipe mouth. This design greatly enhances the clamping force and wrapping effect of the clamp on the welded pipe, and effectively solves the problems of welded pipe loosening and pipe mouth deformation caused by insufficient clamping force. The special structure of the conical hole ensures the uniform distribution of clamping force, so that the welded pipe remains stable during the cutting process and is not prone to deviation. The curved grooves and conical raised belts can guide and disperse the cutting pressure to avoid pressure concentration at a certain point on the pipe mouth, thereby reducing the tolerance deformation of the pipe mouth caused by cutting. This design not only improves the cutting accuracy, but also ensures that the cut pipe mouth can strictly meet the tolerance requirements and can be directly used in subsequent production links without additional processing.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
