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
The present invention relates to a kind of method and stamping die thereof of offering breach, particularly a kind of method and stamping die thereof for gap opening of tubes.
Background technology
In the processing to some tubing, need to offer breach at the mouth of pipe place of tubing.At present, the method for offering breach at the mouth of pipe place of tubing is, tubing is enclosed within on the square punch, and punch is connected on the base, and the tubing by upper punch belling mould place makes tubing break breach under power of enforcement, leaves punch, as shown in Figure 1.But this method, impulsive force act directly on the punch, are easy to make punch to rupture from base, and the method not only may make the breach out-of-flatness of offering, and tubing is easy to occur deformation.
Summary of the invention
The object of the invention is to, a kind of method and stamping die thereof of gap opening of tubes is provided.It can reduce the destruction to mould, and is difficult for when offering breach deformation occurs, and otch is smooth.
Technical scheme of the present invention: a kind of method of gap opening of tubes, it is characterized in that: tubing is enclosed within on the punch (patrix), undershoot to one offers and the required support piece (counterdie) of offering breach in the same size material-dropping hole, punch is clamp-oned material-dropping hole, form the cutting of hand hay cutter formula, thereby set out a breach at tubing.
In the method for aforesaid gap opening of tubes, described support piece is provided with arc groove, and shape conforms to tubing to be processed, and material-dropping hole is located in the arc groove, and forms three cutting edges of door font at arc groove.
In the method for aforesaid gap opening of tubes, described punch upper end is curved, and shape conforms to tubing to be processed.
Realize the stamping die of a kind of gap opening of tubes of preceding method, comprise punch and with the support piece, the support piece is provided with the material-dropping hole with the punch form fit.
In the stamping die of aforesaid gap opening of tubes, described support piece is provided with arc groove, and shape conforms to tubing to be processed, and material-dropping hole is located in the arc groove.
In the stamping die of aforesaid gap opening of tubes, described punch is located on the impact block, and the support piece is located on the base.
In the stamping die of aforesaid gap opening of tubes, described base is provided with guide finger and links to each other with impact block, also is provided with spacing impact pole on the base.
In the stamping die of aforesaid gap opening of tubes, described spacing impact pole comprises a plurality of spacing impact pole different in size, all is enclosed within the blind hole of impact block.
Compared with prior art, the present invention is by being enclosed within tubing on the punch (patrix), and undershoot to offers and the required support piece (counterdie) of offering breach in the same size material-dropping hole, and punch is clamp-oned material-dropping hole, form the cutting of hand hay cutter formula, thereby set out a breach at tubing.Arc groove of the present invention can guarantee that tubing is subject to support in punching course, thereby avoids distortion.Add the position-limiting action of spacing impact pole, the distance that punch presses down is subject to strict restriction, therefore can not press down and excessively produce situation about damaging, and the many designs that length differs, not only can make stressed more even in the undershoot process, and the whole stability that presses down process greatly improves, thereby improves the planarization of otch.

The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples, but not as the foundation to the present invention's restriction.
Embodiment.A kind of method of gap opening of tubes, it is characterized in that: tubing is enclosed within on the punch, and undershoot to offers and the required support piece of offering breach in the same size material-dropping hole, and punch is clamp-oned material-dropping hole, form the cutting of hand hay cutter formula, thereby set out a breach at tubing.Described support piece is provided with arc groove, and shape conforms to tubing to be processed, and material-dropping hole is located in the arc groove, and forms three cutting edges of door font at arc groove.Described punch upper end is curved, and shape conforms to tubing to be processed.
A kind of stamping die of gap opening of tubes, such as Fig. 2～shown in Figure 3, comprise punch 2 and with support piece 3, support piece 3 is provided with the material-dropping hole 5 with punch 2 form fit.Described support piece 3 is provided with arc groove 4, and shape conforms to tubing to be processed, and material-dropping hole 5 is located in the arc groove 4.Described punch 2 is located on the impact block 1, and support piece 3 is located on the base 6.Described base 6 is provided with guide finger 7 and links to each other with impact block 1, also is provided with spacing impact pole 8 on the base 6.Described spacing impact pole 8 comprises a plurality of spacing impact pole 8 different in size, all is enclosed within the blind hole of impact block 1.
