JPS5921481A - Punching and side notching device in production line for metallic strip - Google Patents

Abstract

PURPOSE:To improve the working efficiency of a production device, by disposing a die and a punch near the position where the movement of a weld line stops, and permitting punching and side notching of a metallic strip which is subjected to fore stages such as welding in a short time. CONSTITUTION:A titled device applies punching and side notching, as post stages, on the prescribed positions of a metallic strip which is subjected to welding and trimming stages as fore stages. The above-described device for punching is provided with an upper frame 11 for punching which supports a punch 4 and a lower frame 12 for punching which supports a die 3 engaged with the punch 4 in the crossing part 11a where the device crosses between notcher heads 8a and 8b. The above-described device for side notching is provided with a pair of the notcher heads 8a, 8b which are disposed in the traveling direction of the strip 1 with said strip in-between and the spacing between the same are made adjustable. The strip 1 is subjected to punching and side notching in a short time by the above-mentioned device and the working efficiency is improved.

Description

[Detailed Description of the Invention] The present invention relates to a punching and side notching device in a metal strip manufacturing line ζ, and more specifically, a welding process etc. in a welding device for connecting metal strips. The present invention relates to an apparatus for punching and side notching performed as a post-process.

Conventionally, this kind of thing is shown in FIGS. 7 and 2.

There was one shown in Figure 3. This is the case where the pre-process of punching and notching is welding, and the welding device 2 for connecting the metal tube (IJ tube) is placed on the running line of the metal tube (IJ tube) shown by the chain line. A cylinder S which applies a punching force to the punch ql that later engages the die 3 is supported by the punching upper frame t1. , 7 is a punching lower frame supporting the die 3. After the punching device is created in this way,
A notching device consisting of cylinders 9a and 9b for moving the welded wire plate (+t!l) to the plate side edge is disposed on the notch head which performs 1-nid notching at the end of the welded wire plate (+t!l). 70 is a base. With this configuration, the metal strip 17/ connected by the welding device is moved in the direction of the arrow d from the welding position WLA to the rear B position, that is, the punching position, which is at a distance of the weld line iL/. Move it in the direction shown and stop it, then make a cylinder at the punch 7 position and use the puncher and die 3 to
As shown in FIG. 9, punching bH is performed near the weld line a after this punching is completed.

C with a distance of 2 from the metal strip / from the B position
After moving it to the position and stopping, actuate the cylinders 9a and qb2 of the notching device against the plate side end of weld line a and bring it close to the plate side end of the notcher head ra and gb>metal slide l-1). One side notching was performed, and side notching ca and cbv as shown in FIG. 9 were performed.

Because the conventional device Itr was configured as above.

The punching and side notches 1j and 11 formed near the welding line of the metal strip IJ are moved from the welding position A to the welding position A by a distance of 1/, and are stopped at the t) B position. Next, the robot was moved to position C, which is a distance of 1·a from position B. This is I here
The operation is complicated, and the operation is complicated.
The operation time is also long, which has the disadvantage of reducing the operating rate of the entire metal strip manufacturing equipment.

This invention was made in order to eliminate the drawbacks of the conventional apparatus as described above, and after the completion of the welding process or trimming process, which is a pre-process of the punching and side notching process, the metal strip is cut seven times. Punching and side notching are performed by moving and stopping operations, that is, after the previous process such as welding process or trimming process is completed.

The object of the present invention is to provide a punching and side notching device for a metal strip manufacturing line that can perform punching and side notching in a short period of time and improve the operating rate of the entire metal strip manufacturing equipment.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. S, 6 and 7.

Punching is performed in the vicinity of the weld line a using a punching device consisting of three types, and at the same stop position of the metal strip, the cylinder 9a and qbp are brought close to the welded part plate ends, and the notch heads a and yb are operated to perform side notching.

As described above, the present invention (according to this invention) punching upper frame // punch <z4 supporting transverse portion //a f to opposing notch head between a and gb.

The bearing part of the die 3 of the punching lower frame 7.2 is likewise located between the opposing notch heads a, gb, in the running direction of the metal strip.

The structure is such that the die 3 of the punching device and the punching pin can be placed at the same time near the welding line movement stop at point D, which is the same as the side notching position, so that after the previous process such as welding is completed, the metal sl-IJ Punching and →J-notching can be performed in a short time by moving and stopping 7 times.
Metal strip manufacturing equipment shown.

It has the effect of significantly improving the operating rate.

In one or more of the embodiments, the pre-process is welding, but it may also be a trimming process or any other pre-process, and the same effect can be obtained.
