Description

{A CUTTING DEVICE EASY TO FIX THE PROCESSING PRODUCT OF DIFFERENT SIZE} for easy gripping of workpieces of different sizes

The present invention relates to a workpiece cutting device that is easy to grasp workpieces of different sizes, and more specifically, a plurality of mounting holes capable of mounting a chuck member are formed on a work plate, and thus the size of the workpiece to be processed According to this, the chuck member can be mounted on a mounting hole, and a stopper having a stop function and a weight body having a weight are configured so that the user can arbitrarily select the start of the work of processing the workpiece, and the vertical movement of the weight is performed. Through this, it is possible to obtain the effect of moving speed of a certain work plate, and additionally equipped with a rotating bar that rotates through the hinge and an angle adjusting means that can measure the rotated angle, the gripping of workpieces of different sizes for accurate angle control. It relates to an easy-to-cut workpiece cutting device.

Among the devices used to cut workpieces, etc., it is possible to cut workpieces (non-metal materials, metal materials, etc.) as needed by cutting rotation and linear motion using cutting tools of various shapes. And band sawing machines and circular sawing machines.

Here, in the case of a general band sourcing machine, it means a machine tool that is capable of performing a cutting operation by a cutting rotational movement of a band saw having a band shape and a transfer movement of a workpiece, and is horizontal according to the installation direction of the band saw. It is divided into a vertical expression and a vertical one to select a suitable device according to the user's choice, so that the workpiece can be cut.

And in the case of a circular sourcing machine, it means a machine tool that allows a circular serrated disk to rotate and to perform cutting by the transport movement of the object to be processed. This is to allow the workpiece to be cut in a straight line or diagonally.

As a prior art in this regard, the technical characteristic of the'all-purpose jig for a table rotating cutting tool' is that the base plate along the guide groove is combined with the base plate on which the guide groove is formed and the guide bar and the pusher handle are formed. With a movable structure, the workpiece to be processed is placed on the base plate, and the pusher handle is used to push the base plate toward a rotating tooth disk to cut the workpiece. In addition, a groove having an angle is further formed on the base plate so that a workpiece can be processed at an angle of 45°, and a triangular member having an angle of 30° and 60° is additionally configured on the base plate to cut the workpiece diagonally. It was made possible.

However, in the case of the prior art, the workpieces of various sizes and shapes are cut, but a chuck member for gripping the workpiece is not separately provided. Therefore, when a separate chuck member is not provided, there is a problem in that the fatigue of the worker increases and a problem of safety accidents exists as the user directly performs a cutting operation while holding the workpiece.

In addition, in the case of the prior art, the worker manually cut the work piece while pushing the lathe. At this time, in order to allow the operator to arbitrarily determine the shelf movement start and the shelf movement speed, there is a problem in that an additional cost burden is generated and an increase in the fatigue of the worker is caused.

In the case of the prior art, an angle error may occur depending on the state of the member in that the angle is adjusted using a groove or a triangular member in determining the angle, and when the workpiece is to be cut at another angle , There was a problem that there is a financial and time burden to make a new member.
