Description

An apparatus for cutting and / or punching for manufacturing sign and advertizement board}

The present invention relates to a cutting and / or punching device for the production of signboards or billboards, and the punching arm of the punching machine and the cutting machine of the punching machine on the same drive shaft to perform a series of operations required for the production of signboards or billboards A cutting and / or punching device for the manufacture of signboards or billboards capable of rotating the cutting arms simultaneously or selectively.

In general, in order to produce a small signboard or billboard, a separate cutting device for longitudinal cutting or bending of lightweight steel prefabricated angles is required, and a separate independent device for drilling such as drilling a hole in a plate is required. You need a punching organ.

Therefore, since a large number of expensive independent machines are used to produce signboards or billboards, the cost for producing products increases. In addition, the devices occupy most of the narrow space at each stage of the manufacturing process, resulting in a decrease in the space efficiency of the workshop.

In particular, since most operations are performed using a well-known grinder during cutting of the prefabricated angle, noise is severely generated and the work room becomes dirty, which causes a problem that a worker's work efficiency is lowered.

The present invention was conceived in view of the above problems, and for producing a signboard or billboard having a structure in which a cutting arm member and a punching arm member are coaxially installed on a drive shaft to simultaneously operate a cutting machine and a punching machine in one device. It is an object to provide a cutting and / or punching device.

As shown in FIG. 3, when the driving shaft 50 rotates while the cutting arm 34 is raised, the cutting eccentric cam 32 is rotated together with the driving shaft 50. Then, the cutting arm 34 is lowered to the position shown by the dotted line in the drawing, and the cutting link 81 connected to the cutting arm 34 lowers the cutting block 83 along the cutting guide blocks 85 and 86. Let's do it. Then, the cutter 88 installed in the cutting block 83 cuts the object inserted into the insertion hole 84 while descending along the side of the cutting die 82.

The punch 98 by the reciprocating motion of the punching member 90 by the rotation of the punching arm member 40, with reference to Figure 4 schematically showing a punching arm member and a punching member portion according to a preferred embodiment of the present invention The punching operation will be described. In this case, the punching arm member 40 is rotated by the one-way bearing 47.

As shown in FIG. 4, when the driving shaft 50 rotates while the punching arm 44 is raised, the punching eccentric cam 42 rotates together with the driving shaft 50. Then, the punching arm 44 descends to the position shown by the dotted line in the figure, and the punching link 91 connected to the punching arm 44 descends the punching block 93 along the punching guide blocks 95 and 96. Let's do it. Then, the punch 98 provided in the punching block 93 descends to the upper surface side of the punching die 92 to form a hole in the punching object.

Cutting and / or punching device according to the present invention having the above configuration has the following effects.

First, two independent machines for the production of signboards or billboards can be driven by a single drive source and can be operated simultaneously by installing a clutch member on the drive mechanism, thereby maximizing work efficiency and space utilization.

Second, the one-way bearing can be interposed between the drive shaft and the punching eccentric cam, so that the cutting machine and the punching machine can be used separately, thereby saving costs.

Third, the power of the driving source rotated at high speed is sufficiently decelerated using the belt / pulley means and the sprocket / chain means, and the cutting and / or punching operations are made possible by converting the rotational force by the reduced power into reciprocating motion. do.

Fourth, noise can be prevented by not using a tool such as a grinder that has been employed in the prior art, and the work room can be kept clean, thereby increasing work efficiency.
