Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0018] Example. A method for opening a gap in a pipe, characterized in that: the pipe is placed on the punch, punched down to a supporting block with a blanking hole that is the same size as the required gap, and the punch squeezes into the blanking hole to form Guillotine cut to create a notch in the tubing. The support block is provided with an arc-shaped groove, the shape of which is consistent with the pipe to be processed, and the blanking hole is arranged in the arc-shaped groove, and three cutting edges in the shape of a door are formed on the arc-shaped groove. The upper end of the punch is arc-shaped, and the shape is consistent with the pipe to be processed.

[0019] A stamping die for opening gaps in pipes, such as Figure 2 ~ Figure 3 As shown, it includes a punch 2 and a support bloc...

Abstract

The invention discloses a method for forming a notch on a pipe, which is characterized by comprising: sleeving a pipe on a male die; stamping to a bearing block which has a feeding hole that has the same size as a notch to be formed; and pressing the male die into the feeding hole to form chopping type cutting to form the notch on the pipe. When the method is used, the damage to the die is relieved, deformation is prevented during the formation of the notch, and the cut is flat.

Description

technical field [0001] The invention relates to a method for opening notches and a stamping die thereof, in particular to a method for opening notches of pipes and a stamping die thereof. Background technique [0002] In the processing of some pipes, it is necessary to open a gap at the nozzle of the pipe. At present, the method of opening a gap at the nozzle of the pipe is to put the pipe on a square punch, the punch is connected to the base, and the pipe at the punch is punched by the upper die, so that the pipe is broken under the force. Open the gap, leave the punch, such as figure 1 shown. But in this method, the impact force directly acts on the punch, which is easy to break the punch from the base, and this method not only may make the gap opened uneven, but also the pipe is easy to deform. Contents of the invention [0003] The object of the present invention is to provide a method for notching a pipe and a stamping die thereof. It can reduce the damage to the ...
