Description

PROCESSING JIG FOR WORKPIECE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a workpiece processing jig, and more particularly, to a workpiece processing jig capable of accurately and simply processing a workpiece without power.

In general, in order to process the workpiece into the desired shape, it is necessary to process by using various processing methods. Machining of bending a linear or plate-shaped workpiece at an angle may be performed by hand or by using a beading machine, or bending by a press die. It can be processed by various operations.

When machining by hand in such a workpiece, it can be processed by using a relatively simple equipment, but the machining shape and dimensions of the workpiece are processed differently according to the operator, resulting in inconsistent product and uneven appearance and rough processing. There was a problem.

When machining using a conventional beading machine, the appearance of the workpiece is clean and the processing dimensions are high.However, the machine equipment of the beading machine is more expensive than the working process and it is impossible to operate without electric supply. It was reflected in the accuracy and quantity of the product and there was a problem that the work is impossible if the semi-finished product.

When processing with a conventional press mold, the mold cost is excessively required by making a mold for each hole size of a workpiece. Usually, a machine called a press is required, a lot of noise is generated during work, and a large work space is required depending on the size of the machine equipment. In addition, the need for skilled workers who can vary the machine adds to the burden of labor costs, and it is impossible to work with semi-finished products in the box.

In addition, when the hole machining dimensions of the workpiece are different, the work quantity of the workpiece is generally small, but the replacement time of the mold takes a long time and is troublesome.
