Abstract
The utility model relates to a forming cutter for a punched hole of a liquid collecting pipe, which comprises a cutter body, wherein gradients are formed at both sides of the front part of the cutter body; and cutting edges are arranged at front ends of the gradients. The forming cutter has the following beneficial effects: the gradients are arranged at both sides of the front part of the cutter body; and after punching, deckle edges are effectively removed by using the gradients, and the gradients can lead the opening of the liquid collecting pipe to have a certain gradient so that a flat pipe can be better inserted into a flow collecting pipe to play a role in guiding.
Description
Technical field
The utility model relates to a kind of collector tube piercing and shaping die cutter.
Background technology
At present, common metal material processing adopts cold extrusion, Re Chong more; Or the method processing of dashing of electric pulse and artificial drift, needing specific equipment and frock, the part processing dimensional accuracy is uncontrolled; Because the punching press internal stress is big, some part leaves serious residual stress after punching press; Use in important events to produce phenomenon such as break, cause serious consequence.Versatility is poor, more incompatible process requirements in complex parts and the many products of small lot.
The utility model content
To the deficiency that prior art exists, the utility model provides the little collector tube piercing and shaping die cutter of distortion after a kind of simple in structure, metal material processing.
A kind of collector tube piercing and shaping die cutter is characterized in that: described collector tube piercing and shaping die cutter comprises cutter hub, and the cutter hub front part sides is provided with the gradient, and the front end of the gradient is a blade.
Preferably, described cutter hub is provided with through hole, and the radius of through hole is 4～8mm.
The beneficial effect of the utility model is: the cutter hub front part sides is provided with the gradient, after the punching press, utilizes the gradient effectively to remove burr, and the gradient can make that collector tube leaves mouthful have certain gradient, flat tube can be inserted in the header better, played guide effect.
Description of drawings
Fig. 1 is the work sketch map of the utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further, but the protection domain of the utility model is not limited to this.
As shown in Figure 1, collector tube piercing and shaping die cutter comprises cutter hub 1, and cutter hub 1 front part sides is provided with the gradient 3, and the front end of the gradient 3 is a blade 2.
As shown in Figure 1, collector tube piercing and shaping die cutter is mouth of collector tube cutting, and utilizes the gradient 3 of cutter hub 1 front part sides, the burr of the cutting part of collector tube is removed, well cutting mouthful be the socket of condenser harmonica-shaped tube.
Claims (2)
