Abstract

PURPOSE:To manufacture an oblique welded wire netting continuously, automatically, rapidly and at low cost by dropping transverse wires intermittently to intersect obliquely at a specified angle with longitudinal wires fed continuously after straightening and welding the intersected points of longitudinal wires and transverse wires. CONSTITUTION:A longitudinal wire fed from a steel material coil stand is straightened by a straightening die 3 which is rotated at high speed by a motor 2, and many of such wires are fed in parallel intermittently to welding position by a ball type chuck 35 for pulling out on a pulling out table 18 and a fixed side ball type chuck 36. On the other hand, straightened transverse wires of specified length are dropped intermittently on the longitudinal wires at specified angles of 90-100 deg. or 80-90 deg. to the longitudinal wires. Intersections of above-mentioned longitudinal wires and transverse wires are welded by a multiple-electrode electric resistance welding machine 4 to form an oblique welded wire netting, and cut by a sheet net cutter 23 in conformably to the intersecting angle of the transverse wires.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method and apparatus for manufacturing an oblique welded wire mesh. More specifically, the present invention relates to a method and apparatus for manufacturing a diagonal welded wire mesh, which is convenient for use mainly as a partition mesh or a side mesh in a poultry house with a sloping floor.

Welded wire mesh has excellent strength and the cost of wire material can be significantly reduced compared to conventional tortoiseshell and woven wire meshes, so it has overtaken conventional tortoiseshell and woven wire meshes for use in poultry houses.

In addition, in chicken houses, laid eggs naturally roll down onto the grooves and conveyors.
It is preferable to provide an inclined floor inclined at an angle of about 5°, preferably about 5°.

In order to manufacture partition nets or side nets for poultry houses with such sloping floors, vertical wires (hereinafter referred to as vertical wires) and horizontal wires (hereinafter referred to as horizontal wires) are cut in advance to a predetermined length. A method has been proposed in which a formwork with cutouts is placed so that the vertical lines and horizontal lines fit into predetermined locations on the wooden frame, and the intersections are spot welded one by one by manual operation. This process has been carried out to manufacture specially designed welded wire meshes such as (1) cutting vertical and horizontal lines to a predetermined length, and (2) manufacturing formwork to match the desired shape of welded wire meshes. (3) The vertical lines and horizontal lines are cut to a predetermined length on the formwork. The work of aligning the intersection with the horizontal line and the welding position of the spot welding machine one by one and manually performing spot welding one by one is time consuming and extremely inefficient.

The present invention has been made to eliminate such drawbacks, and has a large number of parallel and intermittent vertical lines that are continuously fed and angles of angles greater than 90 degrees and less than 100 degrees or less than 80 degrees with respect to the vertical lines.
At a predetermined angle of more than 90 degrees, the vertical line is intersected obliquely with the falling horizontal line. After repeating the process, the vertical line is sheared on a shear line that has a predetermined length in the longitudinal direction and is arranged parallel to the predetermined angle to produce a diagonal welded wire mesh.
We focused on the fact that the work of pre-cutting the vertical line to a predetermined length described in item ) and the work described in items (2) to (4) can be eliminated, and automatic continuous production can be performed. This was completed as a result of intensive research and development.

That is, a vertical wire feeding device that feeds a large number of parallel vertical wires from a large number of wire coil stands to a multipolar electric resistance welding machine via a vertical wire straightening device, a multipolar upper electrode, and a multipolar lower electrode. and a vertical line feeding device with mI written on each electrode of the multi-pole lower electrode.
A multi-pole electric resistance bath welding machine having a horizontal line dropping supply device for intermittently dropping horizontal lines one by one on each vertical line fed by the ni1 vertical line feeding device and a multi-pole electric resistance. A shearing means for forming an oblique welded wire mesh by repeating the action of welding each intersection of a vertical line and a horizontal line a predetermined number of times by operating a welding machine, and then shearing the vertical line to a predetermined longitudinal length. A wire mesh shearing machine having An apparatus for producing oblique bath welded wire mesh, characterized by having oblique devices that intersect obliquely at a predetermined angle of more than 90° and less than 100°, or more than 80° and less than 90°, and are held parallel to each other. As a result of manufacturing the partition nets or side nets for poultry houses with sloped floors, it was demonstrated that continuous production can be carried out automatically, excluding the work of cutting the horizontal wires to a predetermined length, and the cost can be reduced. We succeeded in reducing it to a large extent.

In addition, since the diagonal device has a shaft and is configured to be able to rotate from the fine operation G, any diagonal angle can be selected by commands from handle operation or digital switch operation. It is possible to quickly change the setup for manufacturing wire mesh.

Furthermore, the predetermined angle can be set to 90 degrees so that the oblique device can produce a normal welded wire mesh in which vertical lines and horizontal lines are perpendicular to each other. It also becomes possible to produce regular welded wire mesh.
