Abstract
The utility model discloses a leather punched hole punching needle which comprises a needle body, wherein an orifice is arranged on the front end of the needle body, the orifice is a punching knife-edge, and the cross section of the punching knife-edge is in a V shape. The leather punched hole punching needle prolongs the punching time compared with a plain end punching knife-edge with the same diameter when in punching leather, further increases the sharpness of the knife edge, and achieves the purpose of lowering the punching force.
Description
Technical field:
The utility model relates to leather punching upper punch pin, refers in particular to the upper punch pin that can reduce stamping press.
Background technology:
General leather punching at present all select for use be the punching of bearing steel tack towards pin, on same plane, one pair of leather punching die has about the 800-2500 hole approximately towards the pin edge of a knife.The aperture is 1.6mm, and punching press edge of a knife accumulative total has 4000-12000mm, and punching machine must be reached about the 15-35 ton.Because the very big pressure that bearing steel tack need bear towards pin had not only increased noise but also the intensity of the material of mould has been proposed very high requirement, had increased difficulty for the manufacturing of mould, and cost is increased, and had also wasted resource.
Occurred a kind of leather punching punching pin in the past, for example Chinese invention patent ublic specification of application CN2473213Y has just announced a kind of like this leather punching punching pin.Because the blurting out of punching punching pin of using is the blade of tack, punching pin need bear very big pressure in the punching press leather, and material and the manufacturing process to punching pin has very big requirement then.Increase cost like this, also wasted resource required when making.
The utility model content:
The purpose of this utility model is can reduce noise in order to solve the problems of the prior art, to overcome above-mentioned shortcoming, providing, reduce cost, and the New-type leather punching that can reduce the mould manufacture difficulty again is towards pin.
In order to achieve the above object, the leather punching that the utility model provides comprises a needle body towards pin, and this needle body front end is provided with the aperture, and described aperture is the punching press edge of a knife, and the cross section of the described punching press edge of a knife is " V " font.
The described punching press edge of a knife " V " font angle is 120 degree.
Taked after this structure, elongated segment when making the punching press edge of a knife punching press of same diameter in the punching press leather has increased the sword degree again, reaches the purpose that stamping press descends.The noise that punching press produced to leather after stamping press descends has reduced, and the hardness of the material of the pin that liquidates has reduced requirement, to the manufacture difficulty attenuating of mould, has saved the energy in the time of Mould Machining.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a front view of the present utility model.
Embodiment:
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The utility model has the leather punching now towards the existing defective of pin in order to solve, and provides leather punching as shown in Figure 1 towards pin, and it is made of a needle body 1, and the front end of needle body 1 is provided with the aperture, and it is as the edge of a knife 2.
As shown in Figure 1, this edge of a knife 2 is for being " V " font.In order to reach best result of use, the angle of the utility model " V " font edge of a knife 2 is set to 120 degree.
During use, the leather punching is installed on the leather punching die according to certain queueing discipline towards pin, when the punching press leather, the promotion punching machine makes towards the pin edge of a knife presses to leather, because it is 120 degree " V " font structures that the leather punching is adopted angle towards the pin edge of a knife, make each leather punching all on leather, form the punching of a circle easily towards pin, form with towards the regular identical figure of faller gill row, reduced the noise of surrounding environment during towards pin punching press leather, it is happy that our mood is obtained.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
