Description

Technical Field

[0001] The present application relates to the technical field of pipe processing, and in particular to an integrated device for cutting, flattening and chamfering pipes. Background Art

[0002] Cutting and polishing pipe fittings are common processes in pipe processing. Excessively long pipe fittings are cut to the appropriate length. After cutting, the pipe ends will inevitably have burrs. Special tools are needed to process the end faces, external corners, and internal corners of the pipe ends to improve the flatness of the pipe ends.

[0003] In related technologies, pipe fittings are usually processed by operators who transport multiple pipe fittings of the same batch to a circular saw, load the pipe fittings one by one, cut them to a predetermined length, and unload them. The cut pipe fittings of equal length are then transferred to a grinder, where they are loaded one by one, their end faces are polished, and unloaded. The polished pipe fittings are then transported to downstream workstations for subsequent processing such as packaging.

[0004] Regarding the aforementioned related technologies, the cutting and polishing processes of pipe fittings still require a lot of manual intervention during the loading, transferring, and unloading processes, resulting in a low degree of automation. This not only wastes manpower but also reduces pipe processing efficiency. Therefore, it is necessary to provide a pipe processing device that can realize the integrated loading, cutting, transferring, polishing, and unloading of pipe fittings, reduce manual intervention, and improve pipe processing efficiency.

[0075] The number of the second material moving mechanisms 7 in the embodiment is two, and they are arranged between the two polishing machine frames 31 and perpendicular to the length direction of the installation base 34. The second material moving mechanism 7 comprises a third material moving plate 71 fixedly connected to the movable base 35, a pipe supporting frame 72 fixedly connected to the installation base 34, a third guide plate 73 fixedly connected to the installation base 34 and located on the side of the pipe supporting frame 72 close to the cutting device 2, and a fourth guide plate 74 fixedly connected to the installation base 34 and located on the side of the pipe supporting frame 72 close to the unloading frame 5.

[0076] The pipe supporting frame 72 is located between the third guide plate 73 and the fourth guide plate 74, and the top side of the pipe supporting frame 72 can support the pipe to the same height of the polishing station 311. The upper sides of the third guide plate 73 and the fourth guide plate 74 are both arranged downwardly from the side of the cutting device 2 to the side of the unloading frame 5, and the inclination angle of the third guide plate 73 is consistent with that of the storage rack 4 for jointly supporting the pipe to be polished. The upper side of the third guide plate 73 is fixedly connected to the side close to the pipe supporting frame 72 with a limiting protrusion 731 for limiting the pipe.

[0077] The upper side of the third material moving plate 71 is spaced apart to form a first material moving groove 711 and a second material moving groove 712. The first material moving groove 711 is used in cooperation with the third guide plate 73. The third material moving plate 71 is driven by the second pushing mechanism 36 to transfer the pipe limited on the upper side of the storage rack 4 and the third guide plate 73 to the pipe supporting frame 72, and then clamped on the polishing station 311 by the second fixed clamping block 331 and the second movable clamping block 332. The second material moving groove 712 is used in cooperation with the fourth guide plate 74 to transfer the pipe on the upper side of the pipe supporting frame 72 to the fourth guide plate 74, and then slide down to the unloading frame 5.

[0078] The movable base 35 is also fixedly connected with two third material moving plates 71 for assisting in lifting the pipe. The two third material moving plates 71 are arranged on the opposite sides of the two groups of second material moving mechanisms 7 and are located between the two polishing machine frames 31.

[0079] With reference to Figure 1 and Figure 10 The feeding rack 5 includes a support base 51 and a plurality of arc-shaped supporting plates 52. The support base 51 is used to support the feeding rack 5 on the ground. The arc-shaped supporting plates 52 are arranged along the length direction of the support base 51 and are fixedly connected with the support base 51. The upper side of each arc-shaped supporting plate 52 is provided with a soft receiving belt 53 for buffering. When the third material moving plate 71 moves the pipe on the upper side of the pipe supporting frame 72 to the fourth guide plate 74 through the second material moving groove 712, the pipe falls from the fourth guide plate 74 to the soft receiving belt 53 of the feeding rack 5 and falls into the arc-shaped supporting plate 52.

[0080] The material preparation rack 1 in the embodiment can prevent 10-20 pipes to be cut. When the first material moving plate 61 and the second material moving plate 62 are driven to reciprocate by the first pushing mechanism 63, the taking action of the first material moving plate 61 from the material preparation rack 1 and the transferring action of the second material moving plate 62 from the cutting station 211 can be synchronized, thereby improving the continuity of the device in processing the pipes. The storage rack 4 can temporarily store 10-20 pipes to be polished. When the third material moving plate 71 is driven to reciprocate by the second pushing mechanism 36, the third material moving plate 71 can complete the transferring action of the pipe to be polished and the feeding action of the polished pipe at the same time through the first material moving groove 711 and the second material moving groove 712, thereby further improving the continuity of the device in processing the pipes.

[0081] The implementation principle of the pipe cutting and chamfering integrated device in the embodiment is as follows. The guide rod 12 of the material preparation rack 1 is arranged obliquely to guide the pipe to naturally slide down to the upper side of the first material moving plate 61 of the first material moving mechanism 6. The first material moving mechanism 6 transfers the pipe from the material preparation rack 1 to the cutting station 211 of the cutting device 2 through the synchronous lifting movement of the first material moving plate 61 and the second material moving plate 62 and the guiding action of the first guide plate 64 and the second guide plate 65.

[0082] The cutting device 2 includes two symmetrical cutting machine frames 21. The distance between the two cutting machine frames 21 is adjusted by the adjusting mechanism 24 to adapt to pipes of different lengths. The cutting assembly 22 realizes the accurate cutting of the pipe by using the cutter head 221, the cutter seat 222, the driving motor 223 and the cutter seat pushing member 224. The cutting clamping assembly 23 clamps the pipe during the cutting process by using the first fixed clamping block 231, the first movable clamping block 232 and the first clamping block driving member 234 to prevent the pipe from deviating.

[0083] The storage rack 4 is used for temporarily storing the cut pipe to be polished. The second material moving mechanism 7 moves the pipe on the storage rack 4 to the polishing position 311 of the polishing device 3 by cooperation of the third material moving plate 71, the pipe supporting rack 72, the third guide plate 73 and the fourth guide plate 74, and driving of the second pushing mechanism 36.

[0084] The polishing device 3 comprises two symmetrical polishing machine frames 31, each of which is provided with a polishing tool holder 321 and is installed with an end face polishing head 322, an outer corner polishing head 323 and an inner corner polishing head 324. The polishing clamping assembly 33 clamps the pipe in the polishing position 311 by cooperation of the second fixed clamping block 331, the second movable clamping block 332 and the second clamping block driving member 334. The polishing pushing member 336 drives the polishing machine body 313 to polish the end of the pipe.

[0085] The unloading rack 5 is provided with a supporting seat 51 and an arc supporting plate 52, and the arc supporting plate 52 is provided with a soft supporting belt 53 for buffering and collecting the polished pipe. After the pipe is polished, the second material moving mechanism 7 moves the pipe from the pipe supporting rack 72 to the fourth guide plate 74 through the second material moving groove 712, and finally the pipe falls into the arc supporting plate 52 of the unloading rack 5.

[0086] The whole device realizes unmanned operation from material preparation to unloading through coordinated operation and automatic control of each mechanism, greatly improving the efficiency and precision of pipe processing.

[0087] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
