Description

[Technical Field]

[0001] This utility model belongs to the field of metal tube processing technology, and in particular relates to an integrated mechanism for peeling and chamfering metal tubes. [Background Technology]

[0002] The ends of automotive brake pipes need to have their protective coating removed and beveled. To improve the efficiency of peeling and beveling, existing technologies have corresponding processing mechanisms. For example, Chinese Patent Publication No. CN115890259A discloses a beveling mechanism for automotive pipes, which includes a conveying mechanism for transporting pipes to various workstations, a peeling mechanism for removing the surface coating of the transported pipes, and a beveling device for beveling the ends of the peeled pipes. The peeling mechanism and the beveling device are set separately and at different positions on the conveying path of the conveying mechanism. The conveying mechanism first transports the pipes to the peeling mechanism for peeling, and then the conveying mechanism transports the peeled pipes to the beveling device for beveling. This requires two transports, one to the peeling mechanism and the other to the beveling device to complete the peeling and beveling operations sequentially. This not only results in low peeling and beveling efficiency and high production costs, but also a complex structure and large area occupied by the entire processing mechanism.

[0003] Therefore, it is necessary to provide an integrated mechanism for peeling and chamfering metal tubes to solve the above-mentioned technical problems. [Utility Model Content]

Detailed Implementation Methods

[0030] Please refer to Figures 1-7 This embodiment is an integrated mechanism 100 for peeling and chamfering metal tubes. The integrated mechanism 100 for peeling and chamfering metal tubes includes:

[0031] The rotating housing 1 is provided with a guide hole 14 for the metal tube 200 to extend into and a waste discharge port 13 for discharging waste.

[0032] Peeling module 2 and chamfering blade 3 are sequentially arranged inside rotating housing 1. Peeling module 2 peels the end of metal tube, and chamfering blade 3 chamfers the end of the peeled metal tube.

[0033] In this embodiment, the central axis of the peeling module 2 coincides with the central axis of the chamfering blade 3 to facilitate peeling and chamfering of the metal tube 200. The peeling module 2 is installed at one end of the rotating housing 1 with the guide hole 14, and the chamfering blade 3 is installed at the other end of the rotating housing 1, so that the peeling action is performed first, followed by the chamfering action. The metal tube 200 is inserted into the guide hole 14, and the rotating housing 1 drives the peeling module 2 and the chamfering blade 3 to rotate, performing the peeling action. During the peeling process, the metal tube 200 continuously advances until it contacts the chamfering blade 3, and the chamfering blade 3 performs a chamfering action on the peeled end of the metal tube 200. In other embodiments, the installation positions of the peeling module 2 and the chamfering blade 3 can be adjusted according to the actual situation, and are not limited here.

[0034] The peeling module 2 includes a mounting ring 21 and a plurality of elastic peeling components 22 arranged at equal angles along the radial direction of the mounting ring 21.

[0035] The elastic peeling assembly 22 includes a ball cutter 221 for peeling the surface of the metal tube 200, a pressing member 222 pressed against the surface of the ball cutter 221, and an elastic member 223 sleeved around the outer periphery of the pressing member 222. One end of the elastic member 223 abuts against one end of the pressing member 222, and the other end abuts against the inner wall of the rotating housing 1. The elastic member 223 can be a rigid mold spring or other elastic structural member, which is not limited in this embodiment. The pressing member 222 can be a plunger, a bolt, a screw, or other structure, which is not limited in this embodiment.

[0036] In this embodiment, four elastic peeling components 22 are provided, and the four elastic peeling components 22 are arranged at 90° intervals to ensure the stability of the structure. In other embodiments, the number can be set to three, five, or other quantities depending on the actual situation; the number of elastic peeling components 22 is not limited.

[0037] The mounting ring 21 has a clearance hole 211 in the middle for the metal tube 200 to pass through, and several mounting holes 212 radially arranged for mounting the elastic peeling component 22. The sides of the mounting holes 212 are provided with limiting parts 213 to restrict the axial movement of the ball cutter 221. The bottom of each mounting hole 212 is connected to the clearance hole 211 through a first opening 215. After the metal tube 200 is inserted into the clearance hole 211, the first opening 215 facilitates the ball cutter 221 to be inserted into the clearance hole 211 for peeling.

[0038] Several ball cutters 221 are arranged in a ring, and a portion of the outer periphery of each ball cutter 221 extends into the clearance hole 211 through the first opening 215 to perform a peeling action. The bottom wall of the mounting hole 212 is configured as an arc-shaped limiting part 214 to support the ball cutter 221. Two arc-shaped limiting parts 214 can support one ball cutter 221 together, which can prevent the ball cutter 221 from falling into the clearance hole 211. The arc-shaped limiting part 214 is configured to conform to the outer periphery of the ball cutter 221. When the holding member 222 presses on the surface of the ball cutter 221, it can ensure that the ball cutter 221 moves radially along the mounting ring 21 to remove the skin of the metal tube 200, and can prevent the ball cutter 221 from shifting circumferentially along the mounting ring 21.

[0039] The chamfering cutter 3 has a support portion 31 at one end to support the inner ring of the metal tube 200, and several cutting edges 32 arranged around the support portion 31. A conical groove 33 is formed between the support portion 31 and each cutting edge 32 for the metal tube 200 to extend into. A waste discharge groove 34 is formed between two adjacent cutting edges 32 to discharge waste material, and the waste discharge groove 34 extends laterally. When the cutting edges 32 chamfer the outer circumference of the broken arm of the metal tube 200, the support portion 31 extends into the metal tube 200, which can prevent the metal tube 200 from deforming, ensure the stability of the metal tube 200 during chamfering, ensure the consistency of chamfering, and thus ensure the quality of chamfering.

[0040] The rotating housing 1 includes a main housing 11 and a cover 12 installed at one end of the main housing 11. A guide hole 14 is provided on the cover 12. The other end of the rotating housing 1 is provided with a rotating drive component (not shown in the figure) to drive the rotating housing 1 to rotate, which simultaneously drives the peeling module 2 and the chamfering blade 3 to rotate together to complete the peeling and chamfering operations. The main housing 1 and the cover 12 can be assembled by a first fastener, or by other snap-fit ​​connections, or other connection methods, which are not limited in this embodiment.

[0041] The main body shell 11 has a first mounting cavity 111 for mounting the peeling module 2 at one end and a second mounting cavity 112 for mounting the chamfering tool 3 at the other end. After the peeling module 2 is placed into the first mounting cavity 111, the cover 12 is locked onto the main body shell 11 by a first fastener, thus confining the peeling module 2 within the first mounting cavity 11 and achieving the installation of the peeling module 2. After the chamfering tool 3 is placed into the second mounting cavity 112, a second fastener provided on the side wall of the main body shell 11 locks the chamfering tool 3 into the second mounting cavity 112. Correspondingly, the main body shell 11 has a first mounting hole 113 that mates with the second fastener. The second fastener is inserted into the first mounting hole 113 and presses against the outer wall of the chamfering tool 3, thereby restricting the movement of the chamfering tool 3. The first and second fasteners can be pins, screws, bolts, or other fasteners, and are not limited here.

[0042] In this embodiment, since the peeling module 2 is annular with a large diameter and the chamfering blade 3 is cylindrical with a small diameter, the main body shell 11 is correspondingly arranged with the peeling module 2 and the chamfering blade 3, with one end having a large diameter and the other end having a small diameter, and the middle is a tapered transition connection. In other embodiments, the structure of the main body shell 11 can be adjusted according to the structure of the peeling module 2 and the chamfering blade 3, and is not limited to the structure in this embodiment.

[0043] The waste discharge port 13 includes several first waste discharge ports 131 provided on the main body shell 11 and several second waste discharge ports 132 provided on the cover 12.

[0044] When using the integrated mechanism 100 for peeling and chamfering metal tubes provided in this solution, the end of the metal tube 200 to be peeled is inserted from the guide hole 14 into the clearance hole 211. Several ball cutters 221 are pressed against the outer circumference of the metal tube 200, and at this time, the elastic element 223 is in a compressed state. Simultaneously, the elastic element 223 stretches and presses against the holding element 222, thereby pressing against the ball cutters 221. The ball cutters 221 are pressed against the outer circumference of the metal tube 200. At the same time, the rotation drive (not shown in the figure) drives the rotating housing 1 to rotate, causing the ball cutters 221 to rotate together, removing the outer skin of the metal tube 200. While the metal tube 200 is being peeled, the metal tube 200 gradually extends into the rotating housing 1, gradually removing the end of the metal tube 200. The outer skin of the metal tube 200 is peeled off, and the end of the metal tube 200 extends into the chamfering cutter 3. The support part 31 supports the inner ring of the metal tube 200, and the metal tube 200 is stuck in the conical groove 33. The rotary drive (not shown in the figure) drives the rotary housing 1 to rotate, which drives the chamfering cutter 3 to rotate together. The cutting edge 32 chamfers the end of the metal tube 200. After the chamfering is completed, the rotary drive (not shown in the figure) stops driving, and the metal tube 200 is taken out, completing the peeling and chamfering operation of the metal tube 200. The same mechanism provided by this solution can complete the peeling and chamfering operation of the metal tube, with high processing efficiency. Moreover, the integrated mechanism 100 for peeling and chamfering metal tubes provided by this solution has a simple structure, compact design, and small volume.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
