Embodiment 1

[0037] This embodiment discloses a small hole square head chamfer end label shearing device, including a die 1, a guide groove, a reference plate 3, a punch 4, a small hole punch, a guide post 5, a spring 6, a press The discharge plate 7, the small hole punching needle and the punch 4 are connected to the reference plate 3, and the reference plate 3 is connected to the guide column 5; the die 1 is installed on the base, the punch 4, the small hole punching needle and the guide column 5 are all worn Overpressure material unloading plate 7, punch 4, small hole punching pin guide post 5 and pressing material unloading plate 7 are matched in clearance to ensure relative movement, and spring 6 is sleeved on guide post 5.

[0038] This embodiment is aimed at making the small hole square chamfer of the strip metal label, so it is necessary to introduce the specific shape of the square chamfer. The square chamfer is a chamfer that is removed from the four corners of the rectangular lab...

Embodiment 2

[0052] Embodiment 2 discloses a method for cutting a label at the end of a small hole with a square head chamfer, using the device for cutting a label at the end of a small hole with a square head chamfer disclosed in Embodiment 1, comprising the following steps:

[0053] 1) Import the label to be cut into the chute;

[0054] 2) The label to be cut advances gradually with the drive of the power source;

[0055] 3) Every fixed time t1, or every time the label to be cut moves a certain distance s1, the reciprocating power source starts forward, driving the reference plate 3 to descend in the vertical direction, and the pressing and unloading plate 7 Press the label to be cut first, the end face of the punch 4 cuts the label to be cut, the small hole punching needle punches the label to be cut, after the cutting and punching are completed, the reciprocating power source starts in reverse , driving the reference plate 3 to reset, and the pressing and unloading plate 7 pushes the ...

Abstract

The invention discloses a small hole square head chamfer end label shearing device and method. The device comprises a concave mold, a guide trough, a datum plate, a convex mold, a small hole punchingpin, guide columns, springs and pressing and discharging plates. The small hole punching pin and the convex mold are connected to the datum plate, and the datum plate is connected with the guide columns. The concave mold is mounted on a base, the convex mold, the small hole punching pin and the guide columns penetrate through the pressing and discharging plates and are in clearance fit with the pressing and discharging plates, relative motion can be guaranteed, and the springs are connected with the guide columns in a sleeving manner. The end face of the convex mold comprises a rectangular portion and two triangular portions, and the upper end and the lower end of the rectangular portion are each connected with one triangular portion. The rectangular portion is used for cutting adjacent labels, and the triangular portions are used for cutting chamfers of the labels. According to the device and method, small hole square head chamfers of metal labels can still be precisely machined underthe condition of guaranteeing high-efficiency machining.

Description

technical field [0001] The invention relates to the field of metal label production, in particular to a small hole square head chamfer end label cutting device and method. 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 , image 3 shown), and requires small holes to be installed and positioned on the tire mold (by figure 1 , image 3 small holes at both ends of the label). [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 device gives the composition o...
