FIG. 1 is a schematic explanatory view of a hammering apparatus for a metal product according to the present invention.

The present invention relates to a drawing process of a metal product W which has been practiced as a metal processing since ancient times, and more particularly, to a drawing process in which one metal plate is hit and formed with a mechanized hammer. , A base 1, a support 2 erected on the base 1, and a hammer arm 3 supporting a base end slidably and slidably on the support 2 in a horizontal direction.
A hammer mechanism 4 vertically slidably mounted on a tip side of the hammer arm 3, a hammer mounting chuck 5 provided below the hammer mechanism 4, and a hammer mounting chuck 5 below the hammer mounting chuck 5. Hammer 6 detachably attached to
A sliding table 7 slidably mounted horizontally above the base below the hammer 6, and a rotation horizontally slidably mounted above the sliding table 7. A base 8 and a pivotable product forming base support rod 9 having a base end pivotally connected to the turntable 8.
A product forming base 10 provided at the tip of the product forming base supporting rod 9, a product forming base 11 to be mounted on the product forming base 10, and a hammer 6 placed on the product forming base 11 by the hammer 6. 2. A hammering step performed by using the hammering device for metal products W according to claim 1, further comprising a product holding mechanism 12 erected from the slide table 7 for holding a product to be ringed. As a pre-process of
A press working step is performed so as not to cause excessive plastic deformation, and then a smoothing step for removing metal distortion is performed.

First, as a pre-process of a hammering process performed by using the hammering apparatus for a metal product W of the present invention, a press process of forming a plate-shaped metal product W into a cup by press working is performed. However, the pressing process is performed so as not to cause excessive plastic deformation of the metal product W. Then, in order to remove the strain on the metal product W in the pressing process, heating and cooling are performed. The process is performed.

That is, the base 1 of the hammering device for metal products W according to the present invention is a base on which each mechanism described below is disposed. A hammer arm 3 described below is mounted on one side of the base 1. A support column 2 for carrying the support is provided upright.

The hammer arm 3 has a base end supported on the column 2 so as to be pivotable and slidable in the horizontal direction. The hammer arm 4 will be described later around the column 2.
Can be freely turned on the base 1. A turning means (not shown) is mechanically connected by a motor, a gear, a belt, or the like, obtained by a motor, and can be turned through a bearing or the like. The sliding means (not shown) is obtained by obtaining a driving source by a motor, mechanically connected by gears, belts, etc., and interposing a concave groove and a rail slidable in the concave groove.

Next, the hammer mechanism 4 has a hammer ring means for allowing a hammer mounting chuck 5 described later to obtain a drive source in the vertical direction by hydraulic pressure, air pressure, etc., and to be able to advance and retreat with a piston and a cylinder. Sliding means (not shown) is provided so as to be slidable in the horizontal direction with respect to the tip side. A sliding means (not shown) obtains a driving source by a motor and is mechanically connected by gears, belts, etc. A slidable rail or the like is interposed.

Next, the hammer mounting chuck 5 projects downward from the hammer mechanism 4, and
With a hammer removably attached downward.

That is, the hammer 6 is detachably attached to the chuck 5 for attaching the hammer, and is moved up and down by the hammer mechanism 4 to hammer a surface of a metal product W to be described later. The hammer 6 can be replaced by the size of the product W, the molding location, the pattern formed on the surface of the metal product, and the like, and the hammering position of the hammer 6 is determined by turning the hammer arm 3 and sliding between the hammer mechanism 4 and the hammer arm 3. It is to match.

The slide table 7 is mounted on the base 1 so as to be slidable in the horizontal direction, and is operated when the hitting position is moved during hammering. The moving means (not shown) includes a groove formed on either the base 1 or the slide 7 and a rail or the like that slides along the groove. They are mechanically connected by a belt or the like.

Further, the rotary table 8 is mounted on the slide table 7 so as to be rotatable in a horizontal direction, and a rotating means (not shown) obtains a driving source by a motor and uses a gear, a belt, and the like. It is mechanically connected with a bearing or the like, and is activated when the hitting position is moved during hammering.

Next, the product forming base support rod 9 is provided with a product forming base 10 having a rounded top at the tip and a base end pivotally attached to the turntable 8 so as to be pivotable in the vertical direction. The pivoting means (not shown) is driven mechanically by a motor, is mechanically connected by gears, belts, etc., and is pivotable by pivotally mounting the base end of the product forming base support rod 9. It is operated when the hitting position is moved during hammering.

The product forming table 11 is smaller than the metal product W to be hit-formed in advance and is formed in a similar shape. The metal product W for covering the product forming base 10 and hammering with the hammer 6 is used. The product forming table 10 has a large number and is selectively used depending on a metal product W to be formed. The product forming table 10 is replaced according to a forming stage, a forming place, a size, a shape, and the like of the metal product W. To use.

Further, a product holding mechanism 12 for holding the metal product W during hammering is erected from the slide table 7, and a pivotable holding arm is extended at the tip end side. The metal product W to be beaten over the metal 10 is pressed.

And the starting position of these hammers 6;
The drive such as the speed, force, stroke, pivoting of the product forming base support rod 9, rotation of the turntable 8, and sliding of the slide 7 are all electrically connected to the computer. All the processes are controlled up to the stored final process.

[0022]

According to the present invention, the above-described structure is used to mechanize the hit forming conventionally formed by craftsmanship. The plate thickness is constant, no excessive plastic deformation is applied, and the surface is hardened and durable. A metal product can be formed at low cost by mechanization, and has a very significant effect.
