Description

[0001] COMPOUND PRESS DEVICE [0002]

[0001] The present invention relates to a complex press apparatus, in which a first eccentric shaft and a second eccentric shaft are respectively formed in a crankshaft, and a first lift rod and a second lift rod are installed on the first eccentric shaft and the second eccentric shaft The present invention relates to a composite press device capable of performing two pressing processes at a time in accordance with rotation of a crankshaft.

Generally, a press is a machine that applies a force to a material to perform plastic deformation to perform bending, shearing, or section shrinkage, and the press is simply referred to as a press.

Typical examples of the press working are various kinds of shapes produced by plastic deformation by applying compressive force to a metal plate, and they are widely used from precision parts of a watch and a camera to a car body of a vehicle. , Brass plate, aluminum plate, as well as plastic and fiber are used. The characteristic of the press processing is that it can be processed without special heating, it can be processed in exact dimensions and shape in a short time, it is exchangeable, and it is suitable for mass production .

[0003] In such a pressing apparatus, a press type is selected depending on the type of plastic working, and the press is divided into a mechanical press apparatus and a hydraulic pressure apparatus in accordance with a driving method. In the hydraulic press apparatus, Adjustment of pressure and maintenance of pressing force can be controlled more easily than a mechanical press device. However, a mechanical press device in which noises are small and the speed of pressing is low, and press work is performed at a high speed is preferred.

The high-speed mechanical press apparatus may be various ones having a mechanical structure such as a crank, a knuckle joint, a cam, a link, etc. Among them, a crank press apparatus using a crank mechanism is generally used.

Such a crank press apparatus is disclosed in Korean Patent Registration No. 10-0852998.

Such a crank press apparatus is configured such that a single eccentric shaft is formed on the crankshaft so that only one pressing operation is performed when the crankshaft rotates once.

Therefore, when pressing the workpiece in various shapes, the press apparatus must be installed separately for each step, so that the manufacturing cost of the press apparatus is increased, and the workpiece must be transferred for each step.

Further, since the crank press apparatus is not provided with a separate workpiece supplying device and a discharging device, the worker must directly supply the workpiece, so that it takes a long time to inject the workpiece and there is a risk that the worker may be injured by malfunction.

The upper end of the lifting bar 92 is linked with the lifting plate 90 and is moved up and down by a lifting cylinder 94 to be described later. The lifting bar 92 moves the lifting plate 90 up and down.

An elevating cylinder 94 is installed at the lower end of the elevating bar 92. The elevating cylinder 94 is a general cylinder, and a detailed description thereof will be omitted. The elevating cylinder 94 is installed below the elevating bar 92 to move the elevating bar 92 up and down.

That is, the elevating member 88 moves the upper guide roller 78 to the upper side so that the workpiece P can be easily positioned between the upper and lower guide rollers 78 and 80 when the workpiece P is initially moved Direction.

Hereinafter, the operation of the complex press apparatus of the present invention having the above-described structure will be described with reference to FIG. 1 to FIG.

First, the worker grasps the end of the workpiece P in the form of a plate rolled in a roller form and transfers it to the side of the inflator member 50. [

The workpiece P is positioned between the conveyance guide plates 52 and supported on a lower surface by a plurality of conveyance guide rollers 62 provided along an arc surface 53 of the conveyance guide plate 52 .

The conveying guide roller 62 is rotatably installed to guide the workpiece P to the support table 10 side. Is inserted between the upper and lower conveying rollers 66 and 68 of the workpiece P conveyed to the support table 10 side by the conveying guide roller 62. [

The upper and lower conveying rollers 66 and 68 are rotated in one direction by a rotating motor and the workpiece P is moved in the left direction in the right direction of the support table 10. [

The workpiece P is conveyed to the outfeeder member 74 side through the support table 10 at a constant speed by the absorber member 50. [

When the upper guide roller 78 is moved upward and the workpiece P is positioned below the upper guide roller 78 by operating the elevating member 88 of the outfeeder member 74, The roller 78 is moved downward. The crankshaft 20 is rotated in a state where the workpiece P is positioned between the upper and lower guide rollers 78,

The first and second lifting and lowering rods 34 and 36 sequentially move upward and downward in accordance with the rotation of the crankshaft 20 and the two presses are successively formed on the workpiece P, .

When the two press processes are performed on the workpiece P by one rotation of the crankshaft 20, the impeller member 50 and the outfeeder member 74 are operated to move the workpiece P ).

Therefore, two pressing processes are simultaneously performed during one rotation of the crankshaft 20, so that the machining time for the workpiece P can be shortened and the machining efficiency for the workpiece P can be improved .

Further, the absorber member 50 and the outfeeder member 74 are provided on both sides of the support table 10 so that the workpiece P is automatically supplied to the support table 10, It is possible to minimize the number of personnel and shorten the working time.

The scope of the present invention is not limited to the embodiments described above, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.
