Description

Technical Field

[0001] This utility model relates to the field of tooling and mold technology, and more specifically, to a support mold for processing pipe fitting outlet joints. Background Technology

[0002] The processing of pipe fitting outlet joints typically includes steps such as material cutting, forming, thread processing, surface treatment, and inspection. During the processing, corrosion-resistant, high-strength alloy steel or stainless steel is usually selected. The pipe ends are turned, milled, or cold-forged using CNC machine tools or special equipment to ensure that the thread accuracy meets the standards. They are then heat-treated to improve mechanical properties and finally pass a pressure test.

[0003] During processing, since there is a double-layered hollow surface at the end of the pipe fitting outlet, traditional molds can meet the processing support requirements by customizing mold grooves and concave-convex step surface structures when turning or milling. However, due to the high customization cost and structural fatigue at the contact end of the mold groove and the joint, it is difficult to meet the needs of long-line processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing pipe fitting outlet joint mold uses a customized mold groove as a support structure, which is costly and the structure is prone to fatigue during long-line processing. In view of the problems of the existing technology, a support mold for processing pipe fitting outlet joints is provided.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: including an assembly plate and an inner support tube mold, wherein the inner support tube mold is embedded in the assembly plate, and the inner and outer sides of the assembly plate and the inner support tube mold are spaced apart to form concave mold grooves;

[0006] The bottom surface of the assembly tray is fastened to the chassis, and a connecting plate is fastened between the edge of the chassis and the assembly tray. A hinge wheel seat is hinged between the connecting plate and the assembly tray, and a connecting angle bracket is engaged between the hinge wheel seat and the inner support tube mold.

[0007] The four corners of the chassis surface are each fitted with a slide rail seat, and each slide rail seat is slidably fitted with a shear angle seat. A clamping shaft is fixed on the shear angle seat, and a clamping head is provided between the clamping shaft and the inner wall of the inner support tube mold.

[0008] Furthermore, the maximum and minimum included angles between the connecting bracket and the connecting plate are limited by the hinge seat.

[0009] A further preferred embodiment: an axial guide rail frame is embedded between the connecting bracket and the outer wall of the inner support tube mold.

[0010] A further preferred embodiment: the connecting bracket and the guide rail frame are foldable angular frame structures.

[0011] A further preferred embodiment: a pneumatic cylinder is fixed in the chassis, and a telescopic shaft fitting is provided between the shear angle seat and the clamping shaft, and the telescopic shaft fitting is connected to the pneumatic cylinder through an external pipeline.

[0012] A further preferred embodiment: the slide rail seat is a slide rail structure with a shear angle seat as the side slot, and the two ends of the shear angle seat are inclined support structures between the slide rail seat and the telescopic shaft tube.

[0013] The beneficial effects of this utility model are:

[0014] This type of support mold for processing pipe fitting outlet joints provides mold support for the joint structure through the assembly of an assembly plate and an inner support pipe mold. The mold uses the assembly plate as a conventional mold overlap structure, with an adjustable and customizable inner support pipe mold diameter to adapt to the processing requirements of different specifications of joints. Only the corresponding inner support pipe mold matching size needs to be customized according to the dimensions. The adjustable guide rail frame and coupling bracket structure in the assembly plate are used to fix the inner support pipe molds of different diameter specifications respectively. Furthermore, the multi-end support of the structure improves the overall fatigue resistance of the structure and enhances the practicality of the support mold. Attached Figure Description

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-3 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0021] A support mold for processing pipe fitting outlet joints includes an assembly plate 1 and an inner support pipe mold 2. The inner support pipe mold 2 is embedded in the assembly plate 1, and the inner and outer sides of the assembly plate 1 and the inner support pipe mold 2 are spaced apart to form concave mold grooves.

[0022] The bottom surface of the assembly plate 1 is fastened with a base plate 5. A connecting plate 8 is fastened between the edge of the base plate 5 and the assembly plate 1. A hinge wheel seat 6 is hinged between the connecting plate 8 and the assembly plate 1. A connecting angle bracket 7 is snapped between the hinge wheel seat 6 and the inner support tube mold 2.

[0023] The four corners of the chassis 5 are fitted with slide rail seats 11, and each slide rail seat 11 is slidably fitted with a shear angle seat 13. A clamping shaft 3 is fixed on the shear angle seat 13, and a clamping head 4 is snapped between the clamping shaft 3 and the inner wall of the inner support tube mold 2.

[0024] The mold is constructed by clamping and fixing the assembly plate 1 and the inner support tube mold 2. The assembly plate 1 is fixed in the mold groove of the traditional mold by overlapping assembly, and the mold groove between the assembly plate 1 and the inner support tube mold 2 serves as the buckle support end of the outlet connector. The inner support tube mold 2 is a disassembled and replaceable tube structure. The diameter of the inner support tube mold 2 is customized according to the specific connector diameter specification. Compared with the traditional method of customizing a whole mold, its tube structure is simple to manufacture and has low cost, which can cope with the processing of multiple sets of connectors under different size specifications, thus improving the applicability of the mold.

[0025] like Figure 2 As shown, the clamping and fixing of the inner support tube mold 2 and the assembly plate 1 is specifically done by inserting it along the bottom surface of the assembly plate 1 to the other end of the assembly plate 1 in a snap-fit ​​manner. During the process, the outer tube wall of the inner support tube mold 2 is obliquely supported and clamped by the connecting shaft bracket 7. Then, the base plate 5 structure is inserted along the inner tube wall of the inner support tube mold 2. After being fully embedded, the connecting shaft plate 8 is fastened to the surface of the base plate 5 to complete the fixing of the assembly plate 1, the inner support tube mold 2 and the base plate 5. The base plate 5 is equipped with shear angle brackets 13 by diagonally arranged slide rail seats 11. The shear angle brackets 13 are clamped and fixed to the inner wall of the inner support tube mold 2 by the axially arranged clamping shaft 3 and the clamping head 4. The outer end connecting shaft bracket 7 is used to clamp and fix the inner and outer ends to ensure the stability of the overall structure.

[0026] Among them, the maximum and minimum included angles between the coupling bracket 7 and the coupling plate 8 are limited by the hinge seat 6. The coupling bracket 7 and the coupling plate 8 are linked in the same direction through the hinge seat 6 so that the coupling bracket 7 can be released simultaneously when disassembling the contact coupling plate 8. When clamping and fixing, the angle position of the coupling bracket 7 is limited by the limit of the coupling plate 8. That is, the connection between the coupling bracket 7 and the inner support tube mold 2 is fixed in a secondary way, which improves the overall strength of the hinge seat 6.

[0027] Furthermore, an axial guide frame 9 is embedded between the coupling bracket 7 and the outer wall of the inner support tube mold 2, such as... Figure 2 As shown, an axial frame structure that matches the outer wall of the inner support tube mold 2 is used as the overlapping end between the coupling bracket 7 and the inner support tube mold 2 to widen the overlapping area between the coupling bracket 7 and the inner support tube mold 2 and improve the fixing effect of the coupling bracket 7.

[0028] Based on the above, the coupling bracket 7 and the guide rail frame 9 are foldable angled frame structures. The coupling bracket 7 is connected to the upper and lower ends of the guide rail frame 9 by the two ends of the angled structure, so as to cooperate with the folding position of the hinge wheel seat 6 to provide oblique shear support to the fixed end of the guide rail frame 9, thereby improving the strength and axial stability of the entire angled frame structure.

[0029] Furthermore, a pneumatic cylinder 10 is fixed in the chassis 5, and a telescopic shaft fitting 12 is provided between the shear angle seat 13 and the clamping shaft 3. The telescopic shaft fitting 12 is connected to the pneumatic cylinder 10 through an external pipeline. The telescopic shaft fitting 12 with pneumatic cooperation is provided in the structure of the clamping shaft 3. The telescopic height position of the telescopic shaft fitting 12 and the clamping shaft 3 can be controlled by the amount of air pressure filled by the pneumatic cylinder 10, so as to control the clamping height between the clamping shaft 3 and the inner support tube mold 2, adapting to the fixing of inner support tube molds 2 with different groove depths, thus improving the applicability of the mold.

[0030] Furthermore, the slide rail seat 11 has a side-grooved slide rail structure with shear angle seat 13, and the two ends of the shear angle seat 13 are inclined support structures between the slide rail seat 11 and the telescopic shaft tube 12, such as... Figure 3 As shown, compared with axial slotting, the side-grooved slide rail structure can improve the shear strength between the axial direction of the entire clamping shaft 3 and the horizontal direction of the slide rail seat 11 through the stepped surface of lateral limiting, in conjunction with the inclined lifting structure at both ends of the shear angle seat 13, thereby ensuring the fixing effect between the clamping shaft 3 and the inner support tube mold 2. Detailed Implementation

[0032] The mold is constructed by clamping and fixing the assembly plate 1 and the inner support tube mold 2. The assembly plate 1 is fixed in the mold groove of the traditional mold by overlapping assembly, and the mold groove between the assembly plate 1 and the inner support tube mold 2 serves as the snap-on support end of the outlet connector.

[0033] The inner support tube mold 2 is a replaceable tube structure. Its diameter is customized according to the specific joint diameter specifications. The inner support tube mold 2 is clamped and fixed to the assembly plate 1 by inserting it along the bottom surface of the assembly plate 1 to the other end of the assembly plate 1 using a snap-fit ​​method. During this process, the outer tube wall of the inner support tube mold 2 is obliquely supported and clamped by the coupling bracket 7. Then, the base plate 5 structure is inserted along the inner tube wall of the inner support tube mold 2. After complete embedding, the coupling plate 8 is fastened to the surface of the base plate 5 to complete the fixation of the assembly plate 1, the inner support tube mold 2, and the base plate 5. The base plate 5 is mounted using diagonally arranged slide rail seats 11. The shear angle seat 13 is fixed to the inner wall of the inner support tube mold 2 by clamping the clamping shaft 3 and the clamping head 4 arranged axially. It works with the outer end connecting shaft angle bracket 7 to clamp and fix the inner and outer ends. The shear angle seats 13 at each corner can be horizontally translated relative to each other along the slide rail seat 11 to adjust the axial position of the clamping shaft 3 to match the diameter of the inner support tube mold 2. The telescopic height position of the telescopic shaft fitting 12 and the clamping shaft 3 can be controlled by the air pressure filled by the pneumatic cylinder 10 to control the clamping height between the clamping shaft 3 and the inner support tube mold 2, and to adapt to the fixing of inner support tube molds 2 with different groove depths.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
