Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an upper and lower round blade type multi-cutting device for a metal strip welding machine.

FIG. 1 is a diagram of a conventional upper and lower round blade type cutting set for a metal strip welding machine and its troublesome device near the end of cutting. In the figure, 1 is a transverse frame, 2 is an electrode head (electrode disc) attached to this transverse frame, 3 is an upper and lower round blade type cutting set rotatably attached to the transverse frame,
4 is a guide for traversing the traversing frame 1, 5 is a working unit for moving the upper and lower round blade type cutting set 3, 6 is a traversing drive unit for traversing the traversing frame 1, and 7 is a strip to be cut several times. , 8 are the chips.

Upper and lower round blade type cutting set for secondary metal strip welding machine,
The moving device is constructed as described above, and at the end of the traversing movement, in order to prevent the upper and lower round blade type multi-cutting set 3 from interfering with the strip 7 during the traverse movement back to the origin, it is set as shown in the direction of the arrow in the figure. It is necessary to hold the upper and lower round blade type multi-cutting unit 3 in the position shown by A, and at the end of the traverse movement from the origin, it is necessary to move from the position shown in arrow A again for the next trout cutting. It is necessary to return to

A troublesome drive unit 5 was provided for these operations. However, installing a moving drive unit for rolling the upper and lower round blade type cutting set as described above has the disadvantage that the structure is complicated and there is a lot of lost time in the sequence.

The present invention provides an extremely rational up-and-down round-blade type cut-off device that utilizes traverse force without using an intrusion drive unit.

Hereinafter, one embodiment shown in FIGS. 2 to 4 will be described in detail.

2 and 3 show an embodiment of the present invention, and FIG. 4 is a sectional view taken along the line WW in FIG. 2.

Further, FIG. 2 shows the state at a distance x before the end position of the transversal depth, and FIG. 3 shows the shape at the end position of the transverse scale cut. In the figure, numerals 4, 6 to 8 are exactly the same as the subordinate columns described above. Reference numeral 9 denotes an upper and lower round blade type cutting set supported on a transverse frame 14 so as to be rotatable between 00 and approximately 900 by a pin 11.

Further, the pin 11 is located to the left of the center of gravity G as shown in FIG. 10' This is a moving stopper located in a direction symmetrical to the center of gravity G with respect to the pin 11 and attached to an upper and lower round blade type cutting set.

Reference numerals 12 and 13 denote stoppers that hit the movement stopper 10 from a distance x in front of the reciprocating traverse movement end position, respectively. In the troublesome device of the upper and lower round blade type cutting set for metal strip welding machine of the present invention configured as described above, the cutter is moved in the cutting movement direction (arrow 0 direction) before the end or in the origin return movement direction (arrow R
Direction) At a distance x from the front, the movable stopper 10 and the fixed stopper 12 or 13 come into contact.

In this state, the traverse frame moves a distance x to the end, so the upper and lower round blade type bedding set can be moved backwards around the pin 11 using only the force of the traverse drive unit 6. As described above, the time-consuming device of the present invention has an excellent practical effect in that the structure is significantly simpler than the conventional rhombus, and the time loss in sequence operations is shortened.
