Description

Technical Field

[0001] This invention belongs to the field of punching tooling technology, and in particular relates to a tooling for punching pipe fittings. Background Technology

[0002] In automobile manufacturing, many tubular components are required, and some of these components need to be punched. In existing technologies, the surface of thin-walled automotive tubular components is prone to denting and deformation during punching. This severe deformation directly affects product quality, resulting in a high scrap rate and increased production costs. Therefore, it is necessary to develop a punching tooling to improve the quality of tubular components. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a tooling for punching pipe fittings.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A tooling for punching pipe fittings includes a base with a horizontal through hole and a vertical through hole perpendicular to the horizontal through hole. A functional sleeve is inserted into the horizontal through hole. One end of the functional sleeve has a workpiece inlet, and the other end has an inner support insertion port. An inner support is inserted along the second insertion port of the functional sleeve, with a gap for pipe fitting insertion between the inner support and the functional sleeve. A mating section is provided on the side of the inner support near the inner support insertion port. The diameter of the mating section is larger than the diameter of the main structure of the inner support, and the outer wall of the mating section mates with the inner wall of the functional sleeve. A positioning platform is provided at the end of the mating section facing the workpiece insertion port. The functional sleeve has a sleeve through hole corresponding to the position of the vertical through hole, and the inner support has an inner support through hole corresponding to the position of the vertical through hole.

[0006] Furthermore, the functional sleeve is detachably mounted on the base.

[0007] Furthermore, the functional sleeve has a flanged structure at the inner support insertion end.

[0008] Furthermore, the functional sleeve has an inner support guide section at the inner support insertion port and a workpiece guide section at the workpiece insertion port.

[0009] Furthermore, the functional sleeve extends outward from the base at one end of the workpiece insertion port, and the functional sleeve extends outward from the end of the main structure of the inner support member.

[0010] Furthermore, the length of the functional sleeve extending out of the base is 5-10mm, and the length of the inner support extending out of the functional sleeve is 3-10mm.

[0011] Furthermore, the inner support member has a tapered section at one end extending into the functional sleeve, and a retaining edge at the other end protruding from the functional sleeve.

[0012] Furthermore, the inner support and the functional sleeve are simultaneously fixed to the base via connectors.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] This invention features a simple and rationally designed structure, making it easy to use and operate. Simply insert the pipe fitting to be processed into the fitting insertion gap, and then control the punch to perform punching. This results in high work efficiency. Because the pipe fitting is confined within the fitting insertion gap, and the internal support effectively provides support, the pipe fitting is less prone to deformation during punching, ensuring stable and reliable product quality. Furthermore, the pipe punching fixture provided by this invention can be equipped with functional sleeves and internal support components as needed, offering good versatility.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] A tooling for punching holes in pipe fittings, such as Figures 1 to 9 As shown, the device includes a base 1, on which are provided a horizontal through hole 2 and a vertical through hole 3 perpendicular to the horizontal through hole. A functional sleeve 4 is inserted into the horizontal through hole. For example, the functional sleeve is detachably installed on the base. One end of the functional sleeve is provided with a workpiece inlet 5, and the other end is provided with an inner support insertion port 6. An inner support member 7 is inserted along the second insertion port of the functional sleeve. A tube insertion gap 8 is provided between the inner support member and the functional sleeve. The inner support member is a solid rod-shaped structure. A mating section 9 is provided on the side of the inner support member near the inner support insertion port. The diameter of the mating section is larger than the diameter of the main structure 10 of the inner support member, and the outer wall of the mating section mates with the inner wall of the functional sleeve. A positioning platform 11 is provided at the end of the mating section facing the workpiece insertion port. The functional sleeve is provided with a sleeve through hole 12 at the position corresponding to the vertical through hole, and the inner support member is provided with an inner support through hole 13 at the position corresponding to the vertical through hole.

[0030] To facilitate the insertion of the functional sleeve into the horizontal through hole, the functional sleeve has a tapered inner support guide section 15 at the inner support insertion port. To facilitate the insertion of the workpiece into the pipe fitting installation gap, the functional sleeve has a tapered workpiece guide section 16 at the workpiece insertion port. One end of the inner support extending into the functional sleeve has a tapered section 19, forming a feed port between the tapered section of the inner support and the functional sleeve. Preferably, the end of the functional sleeve at the workpiece insertion port extends outward from the base, and the main structure of the inner support extends outward from the functional sleeve. For example, the length of the functional sleeve extending outward from the base is 5-10 mm, and the length of the inner support extending outward from the functional sleeve is 3-10 mm. This structural design greatly facilitates the insertion of pipe fittings into the pipe fitting installation gap.

[0031] In an optional embodiment, the functional sleeve has a flange structure 14 at the inner support insertion end, and a retaining rim 17 is provided at the end of the inner support protruding from the functional sleeve. To improve the structural stability of the inner support and the functional sleeve during the punching operation, in a further improved embodiment, the inner support and the functional sleeve are simultaneously fixed to the base by a connector 21, which can be a screw, such as... Figure 9 As shown, specifically, a fixing hole is provided on the base, and a connecting hole is provided on the eaves and flange structure corresponding to the fixing hole position. The connector passes through the connecting hole of the eaves and flange structure in sequence, and then is screwed into the fixing hole.

[0032] In application, simply fix the base on the punching machine's worktable, aligning the punch with the vertical through hole. Then, install a functional sleeve suitable for the outer diameter of the current pipe fitting onto the base, followed by an inner support component suitable for the inner diameter of the current pipe fitting onto the functional sleeve. After fixing the inner support component and functional sleeve to the base, punching operations can begin. During punching, insert the pipe fitting 20 to be punched into the fitting's insertion gap along the feed inlet position between the tapered section of the inner support component and the functional sleeve. Once the workpiece abuts against the positioning table of the mating section, precise positioning is ensured. Then, control the punch 18 of the punching machine to punch the pipe fitting through the vertical through hole. When unidirectional punching of the pipe fitting is required, simply control the downward displacement of the punch to not exceed the position of the functional sleeve's axis. Figure 7 As shown. When symmetrical drilling is required on both sides of the pipe fitting, simply control the downward displacement of the punch to penetrate the functional sleeve, as shown. Figure 8 As shown in the attached drawings. It should be noted that the base, functional sleeve, and inner support in the instruction manual are schematic structures, and the dimensions of each component can be selected according to actual needs.

[0033] This invention features a simple and rationally designed structure, making it easy to use and operate. Simply insert the pipe fitting to be processed into the fitting insertion gap, and then control the punch to perform punching. This results in high work efficiency. Because the pipe fitting is confined within the fitting insertion gap, and the internal support effectively provides support, the pipe fitting is less prone to deformation during punching, ensuring stable and reliable product quality. Furthermore, the pipe punching fixture provided by this invention can be equipped with functional sleeves and internal support components as needed, offering good versatility.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
