Description

Technical Field

[0001] The utility model relates to the technical field of necking processing, in particular to a steel pipe necking processing device. Background Art

[0002] At present, steel pipes are widely used in many fields of industry. In order to be used in different fields, steel pipes need to be processed in a targeted manner. Generally, steel pipes need to be polished, drilled, chamfered, and shrunken. Shrinking machines are often used to reduce the port of steel pipes. After the shrinking machine reduces the port of the steel pipe, it can be inserted and matched with other pipe workpieces. The shrinking process refers to a molding process in which the mouth of a pre-formed pipe fitting or pipe blank is reduced to the required size through a shrinking die.

[0003] However, the existing shrinking devices have certain defects in actual use. Most of them complete the shrinking process by inserting the steel pipe into the shrinking die seat. On the one hand, the internal grains of the shrinking area are deformed, and the crystal structure produces relative slip between the layers, which can easily lead to an uneven surface of the material and affect subsequent use. On the other hand, directly plugging the shrinking die seat may result in incomplete shrinking. Utility Model Content

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 5 , an embodiment provided by the present invention: A steel pipe necking processing device, including a processing table 1 for necking the steel pipe. One end of it is vertically welded with a fixed plate 2. The necking die base 3 of the necking assembly is fixedly installed in the middle of the fixed plate 2, which can facilitate the subsequent necking processing of the steel pipe in cooperation with the moving assembly and the rotating clamping mechanism. In order to ensure the smooth surface of the processing area and avoid unevenness, a grinding sleeve 18 (the material can be a grinding belt or a grinding stone, etc., selected according to the actual situation) is arranged on the inner wall of the necking die base 3, which can facilitate the auxiliary grinding operation during the necking rotation. At the same time, in order to facilitate the collection of the debris after grinding, a collection box 8 of the collection assembly is arranged at the bottom of the processing table 1 (an exhaust fan, etc. is provided inside it, and the principle is the same as that of a vacuum cleaner, which is a relatively mature technology and will not be elaborated here). One end of the collection box 8 is communicated with a collection pipe 20, which penetrates the processing table 1 and extends into the necking die base 3 to be provided with a collection port 22 (at the end far from the grinding sleeve 18). A collection frame 19 (at the end close to the grinding sleeve 18) is arranged between the fixed plate 2 and the guiding and positioning mechanism, and it is connected with the collection box 8 through a connecting pipe 21. The connecting pipe 21 penetrates the processing table 1 and extends downward, so as to facilitate the unified collection of the debris and the like during the grinding process and ensure the cleanliness.

[0023] Please refer to Figures 1 - 5, in order to ensure that the steel pipe will not shift during necking processing, and at the same time, it can also be moved and rotated to ensure the processing effect. By rotating during necking, the comprehensiveness of necking is ensured. At the same time, the necking part can be polished. The placement seat 6 of the guiding and positioning mechanism can be fixedly installed in the middle of the processing table 1 through screws. The moving pressure block 15 is installed on it through the electric push rod 16. Arc grooves are opened in the middle of the placement seat 6 and the moving pressure block 15, and rubber sleeves 17 are bonded to their inner arc surfaces, which can facilitate the limit and guidance of the steel pipe and prevent it from shifting. One end of the processing table 1 away from the fixed plate 2 is welded with a vertical plate 4, and two hydraulic telescopic rods 9 of the moving components are arranged on its side wall. The output end of the hydraulic telescopic rod 9 is fixedly provided with a moving plate 5. In order to ensure the stability of the movement, a guide block 14 is welded in the middle of the bottom end of the moving plate 5, and a guide groove 7 for the horizontal reciprocating sliding of the guide block 14 is opened on the processing table 1. A motor 10 of the rotating and clamping mechanism is installed in the middle of the moving plate 5, and a rotating plate 11 is fixedly installed at its output end through a coupling. A plug-in ring 12 is welded in the middle of the rotating plate 11, which can facilitate the insertion of the steel pipe. In order to ensure the friction of the insertion, an anti-slip pad 13 is bonded to the inner wall of the plug-in ring 12.

[0024] Working principle: When the present utility model is in use, the steel pipe to be processed is inserted into the plug-in ring 12 through the placement seat 6, and preliminary positioning and fixing can be carried out in cooperation with the anti-slip pad 13. At the same time, the electric push rod 16 contracts to drive the moving pressure block 15 to move downward, and cooperate with the rubber sleeve 17 for guiding and limiting, so as to ensure that the subsequent movement of the steel pipe will not shift. At this time, the hydraulic telescopic rod 9 extends to drive the moving plate 5 to move, and the guide block 14 moves in the guide groove 7 to ensure the stability of the movement. The steel pipe enters the necking die seat 3 and is necked under the action of hydraulic pressure. At the same time, the motor 10 rotates to drive the rotating plate 11 to rotate, and then the plug-in ring 12 and the steel pipe can be driven to rotate. In cooperation with the necking die seat 3 and the polishing sleeve 18, the steel pipe can be comprehensively necked, and at the same time, the necking part can be polished to ensure flatness and the effect of necking, without affecting subsequent use. After the processing is completed, the hydraulic telescopic rod 9 can contract to drive the moving plate 5 to reset. The processed steel pipe is removed from the necking die seat 3, and it can be easily taken off to complete the processing.

[0025] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
