Accordingly, one object of the present invention is to provide a press that can remove burrs in the pressing process.

Another object of the present invention is to provide a display device having a chassis manufactured using the press machine.

A press machine for achieving the above object of the present invention includes a punch and a die. The punch presses the object. The die is disposed below the punch to seat the object. The die has a burr removal portion formed at a portion where the end is seated to remove burrs formed at an end of the object. The burr removing portion has a concave round shape corresponding to the convex round shape of the end portion in order to remove the burr to form the end portion in a convex round shape.

The storage container for a display device for achieving the above another object of the present invention includes a mold frame and a chassis. The mold frame includes a frame and at least one engaging jaw formed on the frame. The chassis has a chassis frame and through holes. The chassis frame extends from one side of the through hole, and includes a hook for supporting the latching jaw with an end where the burr is removed.

According to the present invention, by removing the burr formed on the object in the pressing process, it is possible to prevent damage caused by foreign matters when the object is combined with other structures. In addition, when the object is a chassis of the storage container for a display device, foreign matters may be prevented from being damaged by the process of engaging the chassis where the bur is removed with the mold frame and damaging the display device.

Hereinafter, a press machine and a display device manufactured using the same according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited to the following embodiments.

Press

Example 1

1 is a side view of a press machine according to an embodiment of the present invention. The press is a device for performing a lancing process in a process of manufacturing a chassis for a display device.

The display chassis is manufactured through a press process. The press process includes, for example, a blanking process, a bending process, a basic piercing process, a piercing process, a lancing process, a compound opening process, and a chamfering process.

In each of the above-described processes, a piercing process is a process of forming a through hole to be fastened to a mold frame for a display device in a chassis frame of the chassis. Burrs are formed in the through holes formed through the piercing process.

Next, the punch 110 of the press machine 100 is a linear movement downward by the power to press the object (10). As a result, the object 10 is bent based on the support point 126. Since the pressing surface 112 and the seating surface 122 are inclined downward along the first direction, the object 10 is bent at a predetermined inclination angle. At this time, the portion formed by bending is defined as a hook (14).

As described above, the process of bending the object is referred to as a lancing process, and the object 10 is bent to form the hook 14 by the lancing process.

The die 120 of the press machine 100 has a burr removal portion 124 at a position corresponding to the burr 15a formed at the end 15 of the hook 14. The burr removing part 124 has a concave round shape corresponding to the convex round shape of the end 15 in order to remove the burr 15a to form the end portion 15 in a convex round shape.

Therefore, since the punch 110 strongly compresses the object 10 and supports the object 10 to be seated on the seating surface 122, the end 15 of the hook 14 Having a round shape, the burr 15a can be removed.

Therefore, when the object 10 having the hook 14 is coupled to or after being coupled to another structure, the sharp burr 15a can be prevented from damaging the structure with foreign matter.

According to this embodiment, by removing the burr formed on the object in the lancing process of the pressing process, it is possible to prevent damage due to foreign matters when the object is combined with other structures.
