DETAILED DESCRIPTION

[0023] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0025] As shown in Figure 1 - Figure 4 The present application provides a machine head of a cold rolling pipe machine, which comprises a cold rolling mechanism 1 arranged on the cold rolling pipe machine, and a transmission wheel 2 arranged at the end side of the cold rolling mechanism 1; and further comprises:

[0026] Specifically, as shown in Figure 2 The cold rolling mechanism 1 and the transmission wheel 2 are provided with a disassembly and assembly component 3, which is used for limiting the transmission wheel 2. The disassembly and assembly component 3 comprises a connecting rod 301 which is slidingly connected at the end side of the cold rolling mechanism 1. The transmission wheel 2 is sleeved at the top of the connecting rod 301. The top of the connecting rod 301 is threadedly connected with a connecting plate 303. By arranging the disassembly and assembly component 3 between the cold rolling mechanism 1 and the transmission wheel 2, the worn transmission wheel 2 can be quickly disassembled and replaced by rotating the connecting plate 303 upward, which improves the replacement efficiency and saves the cost.

[0027] Specifically, as shown in Figure 3 The outer peripheral wall of the connecting rod 301 is fixedly connected with a limiting ring 302 which is clamped at the top of the cold rolling mechanism 1. The bottom of the connecting rod 301 is fixedly connected with a ring plate 305. The limiting ring 302 and the ring plate 305 can limit the connecting rod 301, avoiding the situation that the connecting rod 301 is easily dropped from the cold rolling mechanism 1.

[0028] The top of the cold rolling mechanism 1 is fixedly connected with a shaft rod 306, and the outer peripheral wall of the shaft rod 306 is rotationally connected with a rolling rod 304. By arranging the rolling rod 304 on the top of the cold rolling mechanism 1, the metal wire output between the transmission wheels 2 can be rolled and transmitted, avoiding the direct friction between the metal wire and the end side of the cold rolling mechanism 1, which can easily cause the wear of the metal wire and the cold rolling mechanism 1.

[0029] Specifically, as shown in the figure, Figure 4 The end side of the cold rolling mechanism 1 is provided with a limiting assembly 4, which is used for limiting the disassembling assembly 3. The limiting assembly 4 comprises a limiting piece 401 which is slidingly connected in the inside of the cold rolling mechanism 1 and clamped and fixed on both sides of the connecting rod 301. The end side of the limiting piece 401 is provided with a bidirectional screw rod 405. By arranging the limiting assembly 4 on the end side of the cold rolling mechanism 1 and rotating the bidirectional screw rod 405 on the limiting assembly 4, the two limiting pieces 401 can be moved. At this time, the limiting piece 401 can clamp and fix the connecting rod 301 at different positions. The position height of the connecting rod 301 can be adjusted in time according to the size and output height of the metal wire, improving the applicability.

[0030] The inside of the cold rolling mechanism 1 is provided with a sliding groove 4011, and the limiting piece 401 is slidingly connected in the inside of the sliding groove 4011. The inside of the sliding groove 4011 is fixedly connected with a stabilizing rod 404, and the bottom of the limiting piece 401 is provided with a stabilizing groove 4041. The stabilizing rod 404 is slidingly connected in the inside of the stabilizing groove 4041. The stability of the limiting piece 401 when sliding is improved by the stabilizing rod 404.

[0031] Both sides of the limiting piece 401 are fixedly connected with a connecting piece 402 which penetrates through both sides of the cold rolling mechanism 1. The bidirectional screw rod 405 is rotationally connected on both sides of the cold rolling mechanism 1, and the connecting piece 402 is threadedly connected on the outer peripheral wall of the bidirectional screw rod 405. The side wall of the limiting piece 401 is fixedly connected with a rubber pad 403. By rotating the two bidirectional screw rods 405 synchronously, the two limiting pieces 401 can be moved towards each other. The tightness when clamping the connecting rod 301 is improved by the rubber pad 403.

[0032] The specific process is as follows: first, the transmission wheel 2 is sleeved on the top of the connecting rod 301, and the connecting plate 303 is threadedly connected on the top of the connecting rod 301 for limiting; second, the position height of the connecting rod 301 is adjusted according to the size and output height of the metal wire, and the two bidirectional screw rods 405 are rotated synchronously to drive the two limiting pieces 401 to move towards each other until the limiting piece 401 clamps the connecting rod 301 to the desired height; and finally, the cold rolling mechanism 1 is driven to process the metal wire.

[0033] The specific function and operation of the cold rolling pipe machine can refer to the corrugated cold rolling pipe machine with model do-457.

[0034] It should be understood by those of ordinary skill in the art that the above discussion of any of the embodiments is merely exemplary; the above embodiments or technical features among different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for the sake of brevity.

[0035] The present application is intended to cover all such alternatives, modifications, and variations as fall within the broad scope of the appended claims. Accordingly, any and all such alternatives, modifications and variations should be included within the scope of the present application.
