Detailed Description

The present invention will be described in detail below with reference to specific embodiments and the accompanying drawings.

As shown in fig. 1-5, an automatic punching machine for round pipes comprises a pipe accommodating mold 7, an inner cylinder 5 and hydraulic cylinders (1,2,3,4) distributed around the pipe accommodating mold 7, a cavity 6 is arranged between the pipe accommodating mold 7 and the inner cylinder 5, a pipe B to be punched is arranged in the cavity 6, a through hole 50 is formed in the inner cylinder 5, the hydraulic cylinders 1,2,3,4 are distributed with punching heads pointing to the cavity 6, a feeding gripper (8) is arranged above the pipe accommodating mold 7, and the feeding gripper (8) is arranged on an annular transfer disc 9.

As shown in fig. 1, in particular, the inner edge of the tube receiving die 7 is provided with notches 70 for air escape.

Specifically, the inner cylinder 5 is pre-provided with holes for facilitating the rim charge to pass through, the inner cylinder 5 is made of hard alloy, and the inner cylinder 5 generally needs to bear pressure, so that the hardness of the inner cylinder is important.

Specifically, the feeding gripper (8) moves up and down when working, and the control action is realized by adopting an air cylinder or a motor.

As shown in fig. 2 and 5, the feeding gripper 8 includes a grabbing mechanism 82, a rotating screw 81 for rotating the grabbing mechanism 82, and a connecting rod 80, the feeding gripper 8 is used for grabbing and transferring a pipe B to be punched, and the key point of the technology lies in that the feeding gripper 8 moves up and down and can adopt an air cylinder to move up and down, the manufacturing is simple, the pipe B to be punched is generally light, so the feeding gripper 8 of the device can be made light, during operation, the rotating screw 81 rotates, and the rotating screw 81 drives a section of the connecting rod 80 to move up and down, so that the grabbing mechanism 82 can rotate to grab the pipe B to be punched.

As shown in fig. 4, the middle of the pipe B to be punched is an internal control B1, an inner hole B1 is sleeved on the inner cylinder 5, the inner cylinder 5 is provided with a hole for facilitating the rim charge to pass through, the hole is communicated with the lower part, and the punching charge is hung below.

Specifically, the hydraulic cylinders (1,2,3,4) act simultaneously during work and are stressed uniformly.

Specifically, the pipe fitting B to be punched is a copper pipe fitting.

According to the operation steps of the punching machine, the pipe fitting B to be punched is hung into the cavity by the feeding gripper 8, then the hydraulic cylinders (1,2,3 and 4) simultaneously act to punch 4 holes, so that the rim charge can fall into the middle of the inner cylinder 5, and the through hole 50 in the middle of the inner cylinder 5 is connected with the lower position, so that the rim charge can fall to other places and can not be deposited.

The invention has the advantages that the method has the following two main points that four holes are punched at one time, the punching is relatively quick, and the deviation of the holes is relatively small when four holes are punched at one time; secondly adopt material loading tongs 8 to transport and wait to punch a hole pipe fitting B, use manpower sparingly and drop into, realize semi-automatization.

In view of the automated features of the present invention, it is suitable for popularization.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the invention, which is defined by the claims and their equivalents.
