Abstract
A punching head of paper puncher includes a punching head body, in which a blade used to cut off paper is provided at one side of the punching head body, which is a hollow cylindrical shape of the straight pipe. The angle btween the plane where the outer end of the blade edge is, and the normal direction of the punch body is 15 degrees, and a tilt surface with and angle of 25-30 degrees is provided on the inner wall of the blade. The tilt surface changes from thin to thick in the direction from the exterior to the punching head body. The punching head further includes a punching head holder provided at another side of the punch body, and which is also a hollow cylindrical shape of the pipe. The punching head is of stainless steel materials.
Description
Technical field
The utility model relates to a kind of drift of paper punch, relates in particular to a kind of drift of hollow.
Background technology
The cut paper drift of traditional paper punch all is solid, and an end that is used for cut paper is in the shape of the letter V.When punching, need push puncher with bigger pressure, and the paper of once putting into can not be too thick, the paper scrap of being up to falls down, and paper scrap collection easily needs often cleaning at the base position of puncher, simultaneously, because the V font tangent plane of this solid punch cut surface is used long afterwards, the cutting edge rust of drift is no longer sharp.
Summary of the invention
The purpose of this utility model is to provide a kind of drift of paper punch, and its punching speed is fast,
Can once play more thicker paper, the perforating efficiency height, paper scrap is through hollow upwards row, and is time saving and energy saving.
For achieving the above object, the utility model provides a kind of drift of paper punch, it comprises a drift body, one end of this drift body is provided with a cutting edge that is used for cutting away paper, this drift body is the straight tube drum of a hollow, and the plane at the external end edge place of this cutting edge and the normal direction of this drift body are 10-30 degree angle, and the inwall of this cutting edge is provided with the inclined plane of 25-30 degree angle, and being provided with the step of 1.0-1.5mm, the optimum length of this step is 1.2-1.5mm.
The plane at the external end edge place of this cutting edge and the normal direction of this drift body are 15 degree angles.
This inclined plane from the outside to this drift body direction gradually by thin thickening.
The best angle on this inclined plane is 26 degree.
This drift also comprises a punch holder, and it is located at the other end of this drift body, and it also is the drum of a hollow.
The sidewall thickness of this punch holder is bigger than the sidewall thickness of drift body, makes this punch holder can bear bigger pressure.
This drift is a stainless steel material.
This punch holder is a stainless steel material.
The utlity model has following beneficial effect: drift body of the present utility model and punch holder all are hollow, and the resistance that is subjected to when the punching cut paper is less; This plane, cutting edge external end edge place and cockling are capable, and the position, tip of cutting edge successively contacts paper, the easier paper that punctures, follow-up is continued at other positions, can lay the hole fast on paper, especially paper more when thicker effect more obvious.
Description of drawings
Fig. 1 is the stereogram of the drift of the utility model paper punch;
Fig. 2 is the stereogram of another angle of drift of the utility model paper punch;
Fig. 3 is the enlarged drawing of cutting edge among Fig. 2.
The specific embodiment
See also Fig. 1 to Fig. 3, a kind of drift of paper punch, it is a stainless steel material, it comprises a drift body 1, a punch holder 2.
This drift body 1 is the straight tube drum of a hollow, and an end of this drift body 1 is provided with a cutting edge 12.
The plane at the external end edge place of this cutting edge 12 and the normal direction of this drift body 1 are 10-30 degree angle, spend angles for being 15 in the present embodiment, its role is to when punching, this cutting edge 12 successively contacts paper, the just position, tip of the distal-most end of cutting edge 12 at first punctures paper, and other parts continue follow-up and cut brokenly paper fully then.
The inwall of this cutting edge 12 is provided with 25 and spends to the inclined plane 14 of angles of 30 degree, this inclined plane 14 from the outside to this drift body 1 direction gradually by thin thickening, its effect is that the resistance minimum that paper is subjected to allows cutting edge 12 cut brokenly paper fast when punching.The best angle on this inclined plane 14 is 26 degree.
This drift height degree is generally 20.5 millimeters, can increase or reduce its length as required.
This punch holder 2 is located at the other end of this drift body 1, and it also is the drum of a hollow, and its internal diameter is identical with the internal diameter of this drift body 1.The sidewall thickness of this punch holder 2 is bigger than the sidewall thickness of drift body 1, makes these punch holder 2 structures more solid and can bear the bigger pressure that the pressing plate (figure do not show) of this puncher applies.
Drift body 1 of the present utility model and punch holder 2 all are hollow, and the resistance that is subjected to when the punching cut paper is less; This plane, cutting edge external end edge place and cockling are capable, and the position, tip of cutting edge successively contacts paper, the easier paper that punctures, follow-up is continued at other positions, can lay the hole fast on paper, especially paper more when thicker effect more obvious.
Drift described in the utility model adopts stainless steel to make; polishing shaping (application of vacuum under vacuum heat 1030 degree; the carbon gas shiled is shaped); Rockwell hardness is spent between 53 degree 47; when described drift height degree is 20.5 millimeters; can beat paper thickness and be generally 150 to 170, can reach at least 10,000 service life.
