Abstract
The utility model provides the drift that a kind of anti-waste material is taken out of, comprises drift body, sword face, and described drift body is connected with the upper surface in described sword face; Also comprise a breakthrough head, described breakthrough head is tetragonal cone, and the bottom surface of this cone is connected with the lower surface in described sword face, and the value range at the breakthrough angle of described breakthrough head is for being greater than 45 degree and being less than 55 degree; The altitude range of described breakthrough head is 2.7mm ~ 3.3mm.The utility model can overcome because the bad order of part is occurred by taking drift out of waste material during punching, substantially increases production quality and production efficiency.
Description
Technical field
The utility model relates to automobile die production field, particularly relates to the drift that a kind of anti-waste material is taken out of.
Background technology
On automobile stamping production field, due to mould visit inner panel all need design drift, the drift of traditional moulds is all carry out punching with drift planar fashion, wherein, the phenomenon that after conventional drift there will be punching in process of production, waste material is taken back by drift, the quality of extreme influence manufactured parts, this is for a difficult problem one is perplexed greatly in punching production field.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of hole drift that anti-waste material is taken out of, is that the planar fashion of traditional moulds drift is changed over breakthrough mode, first to its drift carry out prepressing deformation a certain amount of after shear again.
The utility model is achieved in that
The drift that anti-waste material is taken out of, comprises drift body, sword face, and described drift body is connected with the upper surface in described sword face; Also comprise a breakthrough head, described breakthrough head is tetragonal cone, and the bottom surface of this cone is connected with the lower surface in described sword face, and the value range at the breakthrough angle of described breakthrough head is for being greater than 45 degree and being less than 55 degree; The altitude range of described breakthrough head is 2.7mm ~ 3.3mm.
Further, described sword face is the surface of flat smooth.
Further, also comprise mould button, described mould button is provided with a through hole and and locates lock-joint, and described drift is arranged in the through hole of described mould button, and described location lock-joint is arranged in mould.
Further, also comprise shaping surface, described shaping surface is connected with the upper surface in described drift body, described sword face respectively.
The utility model has the advantage of: the utility model can overcome because the bad order of part is occurred by taking drift out of waste material during punching, substantially increases production quality and production efficiency.

Fig. 2 is breakthrough head structure for amplifying schematic diagram of the present utility model.
Fig. 3 is the top view of mould button.
Fig. 4 is working state schematic representation of the present utility model.
Fig. 5 is the structural representation that mould button is arranged in mould.
Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 3, the drift 100 that a kind of anti-waste material of the present utility model is taken out of, comprise drift body 1, shaping surface 2, sword face 3, break through 4, described drift body 1 is connected by the upper surface 31 of described shaping surface 2 with described sword face 3, and the bottom surface of the lower surface 32 in described sword face 3 and described breakthrough 4 is connected;
Described breakthrough 4 is tetragonal cone, for rushed waste material is carried out prepressing deformation a certain amount of after row punching again;
The breakthrough angle α of described breakthrough 4 is 50 degree, to be drift in breakthrough distortion can not carry back because angle allows waste material generation brutal fracture be clipped in more than 55 degree to break through head in its effect, or can not waste material deflection be caused not enough because angle is less than 45 degree and affect breakthrough effect;
The height h of described breakthrough 4 is 3mm, i.e. the summit of described breakthrough 4 is 3mm to the distance of the bottom surface of described breakthrough 4, the height h of described breakthrough 4 exceed 2.7mm ~ 3.3mm scope then can affect punching after quality, there is burr phenomena;
Described sword face 3 is the surface of flat smooth, its effect be prevent with the operation of punching bedding-in in cause punching surface to burn pair, there is the harmful effect of punching quality being drawn to material;
Wherein also comprise the mould button 200 matched with this drift 100, described mould button 200 is provided with a through hole 5 and and locates lock-joint 6, described drift 100 is arranged in described through hole 5, and described location lock-joint 6 is arranged in mould 300, its effect to allow punching 5 and drift 100 can not occur because bias occurs stinging the situation collapsed.
Operation principle of the present utility model is as shown in Figure 4 and Figure 5, specific as follows:
First described mould button 200 is arranged on mould 300, by the location lock-joint 6 on described mould button 200, described mould button 200 is fixed on mould 300, when using the utility model, panel beating is placed on described mould button 200, the breakthrough of described drift 100 4 center line are alignd with the axle center of the through hole 5 of described mould button 200, during work, described drift 100 is installed on described mould button 200, then described drift is moved up into for 100 times after in the through hole 5 of described mould button 200, described breakthrough 4 is made to head in described mould button 200 by waste material from described through hole 5, and extrude into mould, waste material now can be avoided to adsorb to be taken out of outside described mould button 200 by the breakthrough of described drift 100 4, reduce the risk of damaging part and mould button 200 by pressure, and substantially increase production quality and production efficiency.
Although the foregoing describe detailed description of the invention of the present utility model; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present utility model and change, should be encompassed in scope that claim of the present utility model protects.
