Small-hole square-head circular bead end portion label shearing device and method

Abstract

The invention discloses a small-hole square-head circular bead end portion label shearing device and method. A female die, a material guiding groove, small hole punch needles, a datum plate, a male die, a guiding column, a spring and a material pressing and unloading plate are included. The male die and the small hole punch needles are connected to the datum plate, and the datum plate is connectedwith the guiding column. The female die is arranged on the base, the male die and the guiding column penetrate through the material pressing and unloading plate, the male die, the guiding column andthe material pressing and unloading plate are in clearance fit, the relative motion can be guaranteed, and the spring is in cup joint with the guiding column. The two small hole punch needles are arranged and located on the two sides of the male die. Blades for cutting the end portion of a square head circular bead half circular hole are formed on the end face of the male die, the blades on the two sides are symmetrically arranged, and each of the blades on the two sides comprises a top circular bead blade, a linear blade and a bottom circular bead blade which are sequentially connected. By means of the small-hole square-head circular bead end portion label shearing device and method, under the situation of high-efficiency machining is guaranteed, the end portion of the square head circular bead half circular hole of a metal label can still be accurately machined.

Description

technical field [0001] The invention relates to the field of metal label production, in particular to a label cutting device and method for a small hole, square head and rounded corner end label. Background technique [0002] Metal labels have a large number of applications in the industrial field, with characters (numbers, letters, various symbols and various patterns collectively referred to) on them. The metal label used to print the vulcanized tire number on the surface of the tire requires that the end of the label be a square chamfered structure (such as figure 1 , figure 2 shown), and requires small holes to be installed and positioned on the tire mold (by figure 1 , 2 small holes at both ends of the label to achieve). [0003] In the existing public literature, the Chinese patent No. ZL201010232108.5 provides a fan-shaped label forming and shearing device, and the Chinese patent publication No. CN2628195 provides a special device for cutting metal strips. The de...
