Abstract
The utility model relates to the technical field of automatic stamping machinery, in particular to a buttonhole for an eyeleting machine. According to the technical scheme, the buttonhole for the eyeleting machine comprises a cylindrical thin-walled button body; an outward circular edge is arranged on the end part of one end of the cylindrical thin-walled buttonhole; the other end of the cylindrical thin-walled buttonhole is a riveting end which is matched with a pressure piece in a riveting way; a shearing port is arranged around the periphery of the end face of the riveting end; and the outer peripheral surface of the shearing port is a cambered surface. Compared with the prior art, the buttonhole has the advantages that the shearing port is adopted, has the advantages of high penetrating power and low pressure, can quickly and completely shear a poster and awning cloth to form a fixing hole to facilitate the action of a stamping head on the cylindrical thin-walled button body, and is overturned outwards to be riveted by the pressure piece, and the riveted buttonhole is firm, smooth and attractive in appearance.
Description
Technical field
The utility model relates to automatic press machinery technical field, is specifically related to riveting eye machine buttonhole, is applied at automatic riveting grommet processed such as the periphery of large format advertisement poster or tarpaulin etc.
Background technology
Traditional, the method of buckleing at the peripheral riveting of large format advertisement poster or tarpaulin metal eye processed is: need the product of riveting eye to beat a hole with special punch at advertisement poster, cloth or nylon etc. first, then buttonhole is put into the following of advertisement poster or cloth etc. and pass from the hole, again compressing tablet is enclosed within on the buttonhole, then with hammer or another special punch the buttonhole riveting on advertisement poster or cloth etc., this a series of actions is finished by manual operations, not only loaded down with trivial details but also waste time and energy, and the buttonhole degree of tightness of riveting system differs, damaged more, of poor quality.
For solving the problems of the technologies described above, people have designed automatic button holing machine, or are called riveting eye machine; Be that 201110107111.9 disclosed a kind of portable button holing machines and China Patent No. are 200720142699.0 disclosed electromagnetic eyeleting machines such as China Patent No.; Used eye button when used eye button still adopts the traditional-handwork riveted joint on the existing riveting eye machine, its structure is: comprise the cylinder-shaped thin wall button, cylinder-shaped thin wall button one end end face is with outside annulus limit, and the other end is the riveted end with the compressing tablet riveted; The port of riveted end is identical with the button wall thickness under this spline structure, and namely it forms blunt mouthful, and is inadequate to the shearing force of advertisement poster and tarpaulin etc., when riveted, easily causing the shearing of advertisement poster and tarpaulin etc. not thoroughly, cause 1) buttonhole and cloth cover structure be not fastening, easily breaks away from selvedge when being subjected to pulling force; 2) the flange place cut of the riveted end of buttonhole is many, or displacement, does not cause the riveted back buckle hole attractive in appearance and easily cut bad stay cord.For addressing the above problem, people are by improving the stamping press of riveting eye machine, and with the raising shearing force, but practical application effect is poor.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of riveting eye machine buttonhole, advertisement poster or tarpaulin etc. is sheared thorough fast, makes the buttonhole behind the riveted firm and smooth attractive in appearance.
For achieving the above object, the utility model provides following technical scheme: a kind of riveting eye machine buttonhole, comprise the cylinder-shaped thin wall button, cylinder-shaped thin wall button one end end face is with outside annulus limit, the other end is the riveted end that cooperates with the compressing tablet riveted joint, and described riveted end end face is provided with sheared edge along circumference.
The outer circumference surface of described sheared edge is arcwall face.
By adopting technique scheme, buttonhole adopts the sheared edge setting, has penetration power strong, the little advantage of pressure, sheared edge can form fixing hole with advertisement poster and tarpaulin excision rapidly and thoroughly, be convenient to staking punch to the effect of cylinder-shaped thin wall button, and turn up and the compressing tablet riveted, the buttonhole behind the riveted is firm and smooth attractive in appearance.
The utility model further is set to: form the annular positioning groove that arranges around the cylinder-shaped thin wall button on the described annulus limit, annular positioning groove is positioned at the annulus limit towards cylinder-shaped thin wall button one side.
By adopting technique scheme, be that the accurate positioning of buttonhole and compressing tablet is reliable, guarantee that further riveted is firm and smooth attractive in appearance.
The utility model further is set to: described annulus limit forms annular protrusion with respect to the opposite side that forms annular positioning groove one side, and annular protrusion is connected with cylinder-shaped thin wall button endoporus cambered surface.
By adopting technique scheme, annular protrusion is to its booster action of annulus limit, and makes buttonhole attractive in appearance, and makes cylinder-shaped thin wall button endoporus level and smooth with being connected of annulus limit, avoids cutting bad stay cord.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the three-dimensional view that the utility model specific embodiment riveting eye machine is used buttonhole;
Fig. 2 is the structural representation that the utility model specific embodiment riveting eye machine is used buttonhole.
The specific embodiment
Referring to accompanying drawing 1, accompanying drawing 2, the disclosed a kind of riveting eye machine buttonhole of the utility model comprises cylinder-shaped thin wall button 1; Cylinder-shaped thin wall button 1 one end end faces are with outside annulus limit 2, and the other end is the riveted end that cooperates with the compressing tablet riveted joint, and described riveted end end face is provided with sheared edge 10 along circumference; The outer circumference surface of described sheared edge 10 is arcwall face, in this specific embodiment, forms sheared edge 10 by the outer circumference surface extruding attenuation with riveted end port; It is that inclined-plane setting or employing inner peripheral surface extruding attenuation form that certain sheared edge 10 also can be outer circumference surface, but said structure arranges lower existence processing inconvenience and the poor shortcoming of shear effect, therefore the utility model preferentially adopts the arcwall face setting.
For firm behind the further assurance buttonhole riveted, form on the described annulus limit 2 and around cylinder-shaped thin wall button 1 annular positioning groove 20 is set, annular positioning groove 20 is positioned at annulus limit 2 towards cylinder-shaped thin wall button 1 one sides; Described annulus limit 2 forms annular protrusion 21 with respect to the opposite side that forms annular positioning groove 20 1 sides, and annular protrusion 21 adopts cambered surface to be connected with the inner hole wall of cylinder-shaped thin wall button 1.In this specific embodiment, by pushing annulus limit 2 towards cylinder-shaped thin wall button 1 one sides, the wall on annulus limit 2 is towards a side bulging deformation that deviates from cylinder-shaped thin wall button 1, form like this annular positioning groove 20 and annular protrusion 21, easy to process like this and processing after, buttonhole not only has attractive in appearance, has increased simultaneously the mechanical strength of buttonhole, makes buttonhole more firm.
