Description

[Detailed Description of the Invention] This invention relates to a blade contact adjustment device for a flat plate punching machine.

In a flat plate punching machine, a cutting blade is set upright on the lower surface of a fixed upper surface plate, and a lower surface plate placed opposite to each other moves up and down to cut on the upper surface of this lower surface plate. A blade receiving iron plate is provided, and a punching paper is provided between the cutting blade of the upper surface plate and the cutting blade receiving iron plate of the lower surface plate to perform punching. In order to make adjustments to make the blade contact uniform between the cutting blade and the cutting blade receiving iron plate, conventionally, a spacer paper for adjustment is inserted into the underside of the cutting blade receiving iron plate, and the cutting blade receiving iron plate and the cutting blade receiving iron plate are adjusted. I was adjusting the contact between the cutting blade and the blade. For this reason, it takes time to adjust the blade contact, which does not improve the operating rate of the flat plate punching machine, and there are disadvantages in that adjustment of the blade contact requires skill. In addition, the degree of contact between the blades changes even when the flat plate punching machine is in operation due to wear of the cutting blades, etc., so it is necessary to stop the flat plate punching machine from time to time to make adjustments, which improves the operating rate. There was a drawback that it could not be done. Therefore, in the present invention, there is a fixed upper surface plate with a cutting blade erected on the lower surface, and a machine that moves up and down and moves the punched paper between the upper surface plate and the lower surface of this upper surface plate. A flat plate punching machine having a lower surface plate for punching includes a cutting blade receiving steel plate disposed on the upper surface of the lower surface plate, a number of hydraulic cylinders disposed inside the lower surface plate, and the hydraulic cylinders. A cylinder rod that pushes up the lower surface of the cutting edge receiving iron plate by the drive of You can easily adjust the blade contact by adjusting the adjustment valve, and even when the flat plate punching machine is in operation and the lower surface plate is moving up and down, you can adjust the blade contact while checking the punching condition. You can adjust the blade contact.

An embodiment of this invention will be described based on the drawings. The upper surface plate 2 of the flat plate punching machine is fixedly arranged, and the wooden pattern 3 is fixedly installed on the lower surface of this upper surface plate 2.
This wooden pattern 3 is provided with a slit 5 corresponding to a punching die, and a cutting blade 4 is embedded in this slit 5 and stands upright. Also, the lower surface plate 10 of the flat plate punching machine
are moved up and down synchronously by a crank mechanism, and a cutting blade receiving iron plate 11 is disposed on the upper surface of this lower surface plate 10, and a large number of hydraulic cylinders 12 are arranged in a lattice pattern on the lower surface of this cutting blade receiving iron plate 11. is fixedly disposed on the lower surface plate 10, and the cylinder rod 13 of this hydraulic cylinder 12 is connected to a through hole 14 formed in the lower surface plate 10.
This cylinder rod 13 is slidably disposed on the
A pressing piece 15 is disposed at the tip of the pressing piece 1.
5 is also slidably disposed in a recess 16 disposed in the lower surface plate 10, and this pressing piece 14 pushes the cutting blade receiving iron plate 1.
Push up the bottom of 1.

Next, let's talk about the action of the blade contact adjustment device.
A punching paper 1 is disposed between the cutting blade 4 of the upper surface plate 2 and the cutting blade receiving iron plate 11 of the lower surface plate 10, and when the lower surface plate 10 is raised and punching is performed, the punching pressure is released. Adjust the adjustment barb of the hydraulic cylinder 12 at the low point to move the pressing piece 14 slightly upward, pushing up the cutting blade receiving iron plate 11 and increasing the evacuation pressure. On the other hand, if there is a location where the punching pressure of the punched paper 1 is high, adjust the adjustment valve of the hydraulic cylinder 12 disposed at that location and move the pressing piece 15 slightly downward to remove the cutting edge. Push down the iron plate 11 to lower the evacuation pressure. This adjustment of the punching pressure of the punched paper 1 can be performed even while the flat plate punching machine is in operation.
