Abstract

The utility model relates to a combined pipe riveting and cutting device, which is formed by combining an existing riveting pipe device and a cutting device to have the functions of the cutting device and the riveting pipe device to process the riveting pipe and to cut the pipe. The utility model has the advantages of simple structure and convenient operation, and is suitable for processing the riveting nozzle and cutting the metal pipe with phi 3 to phi 20.

Description

Combined pipe riveting and cutting device

The utility model relates to a kind of micro metal mouth of pipe cutting and deformation processing instrument, and particularly a kind of combined type riveting pipe cutter is applicable to the riveting mouth of φ 3 to φ 20mm metal tubes and cuts off processing.

At present general riveting pipe device and pipe cutter are independent separately the uses, and riveting pipe device can only be used for the riveting pipe, as the MG-1 snap riveting pipe device of Wuhan City Hardware Tools Factory production.Pipe cutter can only be used for pipe cutting, as the B-1 type pipe cutter of Wujiang county, Suzhou City, Jiangsu Province felling tool factory production.These two kinds of instrumental functions are single, can not replace, and are very inconvenient concerning the user.

The purpose of this utility model is exactly for a kind of pipe cutter function that promptly has is provided, and has the effect of riveting pipe device again, can carry out the combined type riveting pipe cutter of riveting pipe and pipe cutting processing simultaneously.

The utility model adopts U-shaped frame body 3, middle part at U type frame body 3 has a screw, screw rod 2 screws in this screw, the lower end of screw rod 2 is by connecting a conical die 7 than screw rod 2 thin cylindrical journal 9, shed stick 1 is equipped with in the lower end of screw rod 2, side on frame body 3 tops is stretched out a flange, and two support rollers 4 are housed on the flange, position below frame body 3 flanges one side, middle part with bearing pin and cutter lever 5 links, and one of cutter lever 5 is adjacent at axle journal 9 places, and cutting blade 6 is equipped with in the other end, the cutter lever can rotate around bearing pin, on two legs of frame body 3 bottoms, respectively have an oblique square groove respectively in opposite directions, riveting folder 8 is placed on this inclined-plane.

The utility model is simple in structure, and is easy to use, can carry out the processing of pipe cutting and riveting pipe simultaneously, is suitable for riveting system or cuts off the metal pipe material of φ 3～φ 20.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is a C-C cutaway view among Fig. 1.

Fig. 3 is an A-A cutaway view among Fig. 1.

Fig. 4 is a B-B cutaway view among Fig. 1.

Fig. 5 is that 8 structure charts are pressed from both sides in riveting.

The middle part of the utility model U-shaped frame body 3 has a screw, screw rod 2 screws in this screw, the top of screw rod 2 radially has a hole, shed stick 1 is packed in this hole, and the lower end of screw rod 2 is by connecting a conical die 7 than screw rod 2 thin cylindrical journal 9, and the side on frame body 3 is stretched out a flange, two support rollers 4 are housed on the flange, position below frame body 3 flanges one side links with the middle part of bearing pin and cutter lever 5, sees Fig. 1.One of cutter lever 5 is adjacent at axle journal 9 places, sees Fig. 2, and cutting blade 6 is equipped with in the other end, and cutter lever 5 can rotate around bearing pin, on two legs of frame body 3 bottoms, respectively has an oblique square groove respectively in opposite directions, sees Fig. 3, Fig. 4, and riveting folder 8 is placed on this inclined-plane.The structure of riveting folder 8 is seen Fig. 5, it is made up of two strip fixture blocks, link with bolt between them, on every fixture block and another piece fixture block faying face, have the different circular arc thread groove of several radiuses, the degree of depth of each groove is less than the arc radius of groove separately, another fixture block has the circular arc thread groove identical with corresponding groove in corresponding section with it.

During the riveting pipe, pipe is put into the circular arc thread groove that 8 two fixture blocks are pressed from both sides in riveting, clamp with bolt, then, the riveting folder 8 that pipe is housed is put in a pair of oblique square groove of frame body 3, and made die 7 aim at the mouth of pipe, rotate shed stick 1 with hand, drive the screw rod 2 decline extruding mouths of pipe, make the mouth of pipe form horn mouth, last, screw rod is risen, take out workpiece, riveting the plumber promptly finish.

Squeeze the pipe cutting period of the day from 11 p.m. to 1 a.m, pipe is placed on the support roller 4, rotate shed stick 1, make screw rod 2 compressing cutter levers 5, drive the cutting blade extruding and squeezed the pipe that cuts, turne tube relatively rotates cutting blade and pipe, so simultaneously, extruding on one side, rotate on one side, cut off until pipe.
