Description

Technical Field

[0001] The utility model relates to the technical field of forgings, in particular to a high heat-resistant and deformation-resistant flange forging. Background Art

[0002] Forgings are objects to which metal is subjected to pressure, through plastic deformation, to form the required shape or appropriate compressive force. This force is typically achieved by using a hammer or a press. The forging process builds a refined grain structure and improves the physical properties of the metal. In the actual use of the component, a correct design enables the grains to flow in the direction of the main pressure. Forgings need to be consistent from piece to piece without any porosity, excess space, inclusions or other defects.

[0003] For example, a Chinese patent (CN204554139U) discloses a sleeve four-way forging blank, including a tube body 1 and a flange integrally arranged with the tube body, wherein the tube body is a hollow cylinder, and the flanges are two and are arranged at both ends of the tube body, respectively, one of the flanges is provided with an annular protrusion, and the other flange is provided with an annular groove matching with the annular protrusion, so that when stacked, adjacent annular protrusions match with the annular grooves, and since the annular grooves and annular protrusions are provided, and since the end face of the flange is not smooth, the annular protrusion can be stuck in the annular groove when stacked, which can prevent the end face of the flange from sliding, facilitate transportation, and improve safety during transportation.

[0004] The above scheme also has the following technical deficiencies: the above scheme cannot prevent the two adjacent flanges from separating from each other; since the above scheme adopts a ring-mounted protrusion to abut against the annular groove, the two flanges are prevented from sliding in the radial direction of the flanges, but the flanges cannot be prevented from separating in the axial direction; at the same time, the flanges of the above scheme have poor heat resistance and deformation resistance. Based on this, a high heat-resistant and deformation-resistant flange forging is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a highly heat-resistant and deformation-resistant flange forging, which has the advantages of being able to prevent the flange from separating in the radial direction, and solves the problem that the flange is easily separated in the radial direction.

[0008] Furthermore, the flange includes two cast steel layers fixed on the left and right sides of the pipe body, a heat-resistant layer is fixed on the side of the cast steel layer away from the pipe body, an anti-tensile layer is fixed on the side of the heat-resistant layer away from the cast steel layer, an anti-deformation layer is fixed on the side of the anti-tensile layer away from the heat-resistant layer, and a wear-resistant layer is fixed on the side of the anti-deformation layer away from the anti-tensile layer.

[0009] Furthermore, two limiting holes are provided on the left side of the flange on the right side, and the limiting rods are abutted in the limiting holes.

[0010] Furthermore, a slide groove is provided on one side of the mounting plate, and the moving rod slides in the slide groove.

[0011] Furthermore, a bearing seat is fixed to the left side of the inner wall of the mounting plate, and the screw rod rotates in the bearing seat.

[0012] Furthermore, one side of the annular flange is fixed to the side of the wear-resistant layer away from the anti-deformation layer, and the annular flange can move in the annular groove.

[0013] Furthermore, the heat-resistant layer is an asbestos layer, the anti-stretching layer is a rubber layer, and the anti-deformation layer is a stainless steel layer.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The high heat-resistant and deformation-resistant flange forging is provided with a fixing mechanism on the flange, so that two adjacent flanges can be fixed together, avoiding the flanges from being separated from each other in the radial direction, thereby avoiding the flanges from sliding against each other, which is beneficial for transportation and fixing. By fixing flanges at both ends of the pipe body, the heat resistance of the flange can be increased through the heat-resistant layer, and the deformation resistance of the flange can be increased through the anti-deformation layer.

[0024] The fixing mechanism 400 in this embodiment fixes the two flanges 200 by abutting the limiting rod 408 in the limiting hole. The handle 403 is used to facilitate the rotation of the screw rod 402. The screw rod 402 is used to drive the slider 404 to move left and right. The slider 404 can drive the moving rod 405 to move.

[0026] See also Figure 1 and Figure 2 In order to improve the heat resistance and deformation resistance of the flange 200, the flange 200 in this embodiment includes two cast steel layers 201 fixed on the left and right sides of the pipe body 1, a heat-resistant layer 202 is fixed on the side of the cast steel layer 201 away from the pipe body 1, and the heat-resistant layer 202 is an asbestos layer.

[0028] It should be noted that asbestos refers to silicate mineral products with high tensile strength, high flexibility, resistance to chemical and thermal corrosion, electrical insulation and spinnability. It is a general term for natural fibrous silicate minerals; rubber, also known as elastomer, is an elastic polymer. Rubber is divided into two categories: natural rubber and synthetic rubber. The source of natural rubber is rubber tree and rubber grass; synthetic rubber is mostly synthesized from monomers through polymerization reaction and can be produced on a large scale. Its output is many times higher than that of natural rubber. Stainless steel, the full name of stainless acid-resistant steel, refers to a series of steels with high chemical stability in air, water, salt aqueous solutions, acids and other corrosive media; it is an alloy steel containing more than 13% chromium, and some also contain other elements such as nickel and titanium.

[0029] The working principle of the above embodiment is:

[0030] When the two flanges 200 need to be connected together, the annular flange 3 on one flange 200 is aligned with the annular groove 5 on the other flange 200, and the annular flange 3 is placed in the annular groove 5, and then the handle 403 is rotated, the handle 403 drives the screw rod 402 to rotate, the screw rod 402 drives the slider 404 to move, the slider 404 drives the moving rod 405 to slide in the slide groove, the moving rod 405 drives the connecting plate 406 and the connecting rod 407 to move, and the connecting rod 407 is connected to the connecting plate 406. 07 drives the limiting rod 408 to enter the limiting groove, thereby realizing the installation of the flange 200. When the flange 200 is at high temperature, the heat-resistant layer 202 can increase the heat resistance of the flange 200. When the flange 200 is bent, the anti-deformation layer 204 can prevent the flange 200 from excessive bending and deformation. When the flange 200 is bent, the anti-tensile layer 203 can prevent the flange 200 from being easily broken. The wear-resistant layer 205 can improve the wear resistance when the two flanges 200 have relative friction.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
