Problems solved by technology

For example, in the case of processing a lead frame by etching a strip-shaped metal material, if the bending is large, it is difficult to open holes at a fixed interval by pressing steps, resulting in a significant decrease in product yield

Embodiment

[0060] Examples of the present invention are shown below, and the examples are provided for better understanding of the present invention and its advantages, and are not intended to limit the invention.

[0061] For the Cason copper alloy (2-4 mass% Ni-0.4-1.0 mass% Si-Cu) having the tensile strength, Vickers hardness, plate thickness and plate width shown in Table 1, using image 3 The slitting machine equipment with the structure shown is used for slitting processing of metal raw materials. Regarding each embodiment and invention example, the length (110a, 110b) of the meandering prevention plate at the front stage of the slitter, the presence or absence of the meandering prevention plate (140a, 140b, 160a, 160b, 170a, 170b) at the rear stage of the slitter, the longitudinal The width of the strip-shaped metal material after cutting is also adjusted as described in Table 1.

[0062] The operating conditions of the slitting machine equipment are as follows.

Abstract

The purpose of the invention is to provide metal strip material having a high degree of parallelism after slitting and a slitting method to acquire such metal strip material and to provide a method toreasonably measure strip material meandering. Provided are metal strip material, a slitting method, and a method for measuring strip material meandering, wherein the metal strip material is characterized in that the maximum gap for each 1 m in the longitudinal direction of the metal strip material is 0.12 mm or less when measuring, every 50 mm, the gap with a straightedge ruler in a direction perpendicular to the longitudinal direction of the metal strip material by bringing the straightedge ruler in contact with the side face of the metal strip material in the longitudinal direction.

Description

technical field [0001] The invention relates to a strip-shaped metal material, a slitting method for obtaining the strip-shaped metal material by continuously cutting the metal raw material into a specific width along the length direction, and a meandering measurement method for the strip-shaped material. Background technique [0002] In the production line of metal raw materials such as mild steel, copper, copper alloy, stainless steel, etc., the metal raw material is conveyed in the length direction and the other is made into the final plate thickness through rolling steps, and then slit into specific widths according to the user's expectations , and are each wound into a coil shape and shipped. As a method of slitting a metal material into a predetermined width, a method of passing the metal material between slitters having circular knife cutters arranged up and down is generally performed. [0003] If the shape of the metal raw material before being slit is undulating r...
