Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows: referring to fig. 1-5, the present embodiment discloses a reciprocating feeding mechanism, which includes a frame 1, a movable plate 2 mounted on the frame 1 and moving along a length direction of the movable plate, a rear movable chuck 3 mounted on the movable plate 2, a fixed chuck 4 mounted on the frame 1, a clamping device 5 mounted on the frame 1 and corresponding to the fixed chuck 4, and the clamping device 5 clamping or releasing a long workpiece.

Preferably, the rear moving chuck 3 is a power chuck or a pneumatic chuck.

Preferably, the claws of the rear moving chuck 3 are heightened claws.

Preferably, the fixed chuck 4 is a power chuck or a pneumatic chuck.

The rear moving chuck 3 and the fixed chuck 4 used in this embodiment are common components in the prior art, and the working manner and structure thereof are well known technology and will not be described herein.

The working process and principle of the embodiment are as follows:

the length of a workpiece on the existing pipe cutting machine is generally larger than 6m, and the distance between the rear movable chuck 3 and the fixed chuck 4 is more than 6 m. A slightly thicker tube may not be able to work with a problem, but a thinner tube does not work and the tube will deform significantly under the influence of gravity.

The long workpiece passes through the movable chuck 3 and the fixed chuck 4.

After the long workpiece to be machined at one section is machined, the clamping device 5 clamps the long workpiece, the rear moving chuck 3 loosens the long workpiece, the moving disc 2 drives the rear moving chuck 3 to backward move to a set distance, the rear moving chuck 3 clamps the workpiece, the clamping device 5 loosens the workpiece, and machining continues.

And continuously circulating according to the process until the processing raw materials are used up.

The reciprocating feeding mechanism is equivalent to divide a long workpiece to be processed into a plurality of sections for feeding in a repeated feeding mode, so that the deformation of the long workpiece is reduced, the problem of deformation of the long workpiece during processing and feeding is solved, and the loss of the workpiece is reduced.

Example two: as shown in fig. 1, the present embodiment discloses a reciprocating feeding mechanism, which has a structure substantially the same as that of the first embodiment, except that the moving plate 2 of the present embodiment is driven by a lead screw or a linear motor to move along the length direction of the frame 1; the distance of the reciprocating movement of the movable plate 2 is conveniently controlled.

Example three: as shown in fig. 2 and fig. 5, the present embodiment discloses a reciprocating feeding mechanism, which has a structure substantially the same as that of the first embodiment or the second embodiment, except that the clamping device 5 of the present embodiment includes an air cylinder 51, the air cylinder 51 is fixed on the frame 1, a bidirectional telescopic air cylinder 52 is installed at a moving end of the air cylinder 51, and clamping blocks 53 for clamping a long workpiece are fixed on both moving ends of the bidirectional telescopic air cylinder 52.

The air cylinder 51 and the bidirectional telescopic air cylinder 52 used in this embodiment are both pneumatic driving components in the prior art, and their working modes and structures are all known technologies, which are not described herein again.

In use, both the cylinder 51 and the bi-directional telescopic cylinder 52 are connected to a gas source.
