JPS62214835A - Punching method for thin sheet by elastic body punch - Google Patents

Abstract

PURPOSE:To continuously perform a punching with high positional accuracy and high production efficiency in a simple mechanical structure by using a hard metal roll for a die and by using the elastic body roll of a synthetic resin, etc. for the punch. CONSTITUTION:A punch roll 7 is made by winding a plate of the elastic body 14 having the adequate material and thickness of an urethane, etc. on the outer surface of the core roll having appropriate strength and by bonding the both. A die roll 8 is made by providing the die hole 15 having adequate shape and depth in the surface of the metal roll having adequate material and strength. The space between both rolls 7, 8 is pressed each other with adequate method, by rotating at equal speed in this state, by inserting the thin sheet 13 of the material between said both rolls 7, 8 and the punching is performed with feeding to the front part the thin sheet 13 with the friction force of both rolls 7, 8. This is suitable for punching the grid for the board of various batteries.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the invention The purpose of the invention is to continuously drill holes in FA&fI in extremely thin ropes and other metal plates.

(2) Industrial application field In addition to drilling holes in the grid for the base of 8-turret batteries, it is also used for drilling holes in 48-shaped 51-slope parts made of class 8 metal.

(3) Main text of 1 story 1 sintering type alkali @'e1 The grid for the pond base is made of snow 1
It is used to prevent shrinkage during sintering, and is currently used in the range of 0.15-0.3m.
mt! nickel wire wrapped in 8 to 30 meshes,
Or 0.1mm thick! ! A perforated plate with small holes of 0.1 to 2.0 mm in diameter is used. Bridge plates for fishing and snow storage ponds are also used for the same purpose, or the holes are much larger than in the example above, or thin plates with mesh hooks are used, and conventionally they were mainly made of metal. i by type! ! It was originally manufactured by drilling, but due to the performance of the battery, it was required to use a fishing board, which was less easy to construct, so holes were made using punches and dies.

In these two examples, between the punch and die made of rigid material that moves up and down? 3 processing book board 11+! Drilling is done after passing the time.

In this current drilling method, while the punch is moving up and down, the thin plate is rapidly fed to a hole at a predetermined drilling pitch, and after being drilled at this 19, the top and bottom of the hole. Power is sent out from the 91st floor to the gate that stops h. Drilling using a one-rod T-punch vertical/force method has low positional accuracy and low production efficiency.

Continuously attach the die to the corresponding A9 side of the other roll, and handle those faces while rotating both rolls.
I've passed Roe 4O, and if I can solve it, I'll need Shinta's approval to make the Bonti Roll and Tights, and especially the relative rotation accuracy of the Moon Roll. Moreover, due to mutual interference between the tip of the punch and the end of the die, there is also a restriction on the pitch of the hole to be drilled. %11 fishing is also a lifetime.

In the present invention, an elastic body made of a flexible material with a thickness of about 100 ml is attached to a core roll and used in place of the punch roll, and the conventional intermittent method and the rigid punch roll and die roll are used. P11 was determined by the continuous method.

The outer surface of the core roll, which has an appropriate strength, is covered with a stretchable body having an appropriate material and thickness. Holes of appropriate shape and depth are formed on the surface of the roll made by Zengaku, which has a number of layers of ?48, and is used as a die roll. Pressure is applied to each other by an appropriate method between the two rolls, and in this state, Rotate/melt at a constant speed.

When the A plate of the material is inserted between both rolls, the A plate is sent forward by the frictional force of the two rollers and holes are drilled.

This method allows the required force of 8 strokes to be carried out continuously and overcomes the drawbacks of the intermittent up-and-down method or methods requiring the use of expensive punch rolls.

The ¥4 figure is an enlarged photo of a product that has been drilled using the above-mentioned device.

Using the device shown in Fig. N1, four holes of 0.05 mm + the diameter were made. The elastic punch roll is made by sweeping 12 mm of urethane onto the core electric roll, and the metal die roll has die holes with a diameter of 2 mm in the radial direction of the roll as die holes around the 9 edges of the roll. It has holes. Figure 3 shows the state of holes drilled using this method.

In the above example, the punch roll and die roll are cylindrical, or the roll 881I is straight (it is also possible to use a crown 0-roll with a different shape, and the elastic band plate is a caterpillar-shaped metal plate. 6. The heald conveyor of the elastic body is driven by the station@rl shaft, and the thin plate of material is inserted between the die rolls mentioned above to make holes. Alternatively, a method may be considered in which a thin plate of material is inserted between an elastic belt and a die roll, or a thin plate of material is inserted between support rolls with a flat circumferential surface.

With this invention, the conventional die and punch can be punched without having to move up and down. Compared to other operations, the efficiency of the chief operator is greatly improved because the processing can be carried out continuously, making it possible to produce a large amount of work in a short period of time.

In addition, since the rotary movement/h is constructed by a circular structure that is more efficient than vertical movement, the cost of the jJ18 can be reduced.
