Description

Technical Field

[0001] The utility model relates to the technical field of pipe forming, in particular to a pipe line split structure rounding die. Background Art

[0002] Pipe fittings are long, hollow, round metal tubes widely used in industrial pipelines for the petroleum, chemical, medical, food, light industry, and mechanical instrumentation industries, as well as in mechanical structural components. Furthermore, their low weight, while maintaining the same bending and torsional strength, makes them widely used in the manufacture of mechanical parts and engineering structures. Currently, a pipe production line primarily consists of a loading area, forming area, welding area, grinding area, rounding area, and cutting area. The rounding area is responsible for rounding the pipe fittings, requiring the use of a rounding mold.

[0003] Traditional rounding area molds will have grooves in the middle after long-term use, affecting product quality. The only solution is to replace the mold with a new one, which is expensive and has a short service life.

[0004] Based on the above technical problems, technical personnel in this field urgently need to develop a pipeline split structure rounding mold with simple structure, longer service life, improved product quality and low replacement cost. Utility Model Content

[0005] The utility model aims to provide a pipe-making line split-structure rounding die with a simple structure, a longer service life, improved product quality and low replacement cost.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] The utility model discloses a pipe production line split structure rounding mold, which comprises:

[0008] A first split mold, which is made of a high-hardness material; and

[0009] The second split mold and the third split mold are respectively connected to both ends of the first split mold. The second split mold and the third split mold have the same structure and are arranged along the first split mold in a mirror image.

[0010] Preferably, the width of the first split mold is 8-12 mm, most preferably 10 mm.

[0011] Preferably, the second split mold and the third split mold are both connected to the first split mold via two hexagon socket screws.

[0012] Preferably, the first split mold is made of cr12 material.

[0013] Further, both the second split mold and the third split mold have arc surfaces, and the arc surfaces extend up and down along the edge of the first split mold.

[0014] In the above technical solution, a roundness correction mold for a pipeline split structure provided by the present utility model has the following beneficial effects:

[0015] The roundness correction mold for a pipeline split structure of the present utility model has a simple structure. The traditional integrated mold is designed into a split structure. When a groove appears in the middle part of the first split mold after long-term use, only the local part needs to be replaced, which saves costs. Moreover, the first split mold in the middle part of the present utility model is made of high-hardness material, which further improves and enhances the product quality, and has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for use in the embodiments. Obviously, the drawings described below are only some embodiments recorded in the present utility model. For those of ordinary skill in the art, other drawings can also be obtained based on these drawings.

[0017] Figure 1 It is a schematic diagram of a roundness correction mold for a pipeline split structure provided by an embodiment of the present utility model.

[0018] Description of the reference numerals:

[0019] 1. First split mold; 2. Second split mold; 3. Third split mold. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0021] See Figure 1 as shown;

[0022] A roundness correction mold for a pipeline split structure of the present utility model, the roundness correction mold includes:

[0023] A first split mold 1, which is made of high-hardness material; and

[0024] A second split mold 2 and a third split mold 3 respectively connected to both ends of the first split mold 1, the second split mold 2 and the third split mold 3 have the same structure and are arranged mirror-symmetrically along the first split mold 1.

[0025] As a preferred technical solution of this embodiment, the width of the first split mold 1 is 8 - 12 mm, and most preferably 10 mm.
