The present invention relates to a burr removing device of a metal case, comprising: a middle plate provided with a plurality of cutting tools having a pulley fixed thereto; A jig forming a penetrating seat; Bracket is fixed to the shaft is composed of a plurality of pulleys, to fix the middle plate and jig in order to the bottom and a certain height, install a plurality of brackets around the middle plate, and secures the belt around the pulley of the bracket, The pulley of each bracket and the pulley combined with the cutting tool are connected by a belt, and a burr removing device configured to rotate the shaft of one bracket by a motor is mounted, the metal case is seated and pressed to the jig seating portion, and the motor is rotated. This allows the burr to be removed quickly at once by rotating the cutting tool.

In general, the mobile phone case is made of a large amount of polymer materials, but in consideration of the strength, recently made of light metals such as aluminum alloy and magnesium alloy, this trend, the body of the digital camera, notebook body, case portable electronics It is widely used in products.

The method of making a case made of metal is made by a die casting method, which dissolves dissimilar metals to form an alloy with magnesium, injects the molten metal into a mold, solidifies it, and then demoulds it.

However, due to the nature of the die-casting, the molten metal flows in a wave shape or protrudes due to pinholes, which causes scattering (multiple) of the burrs scattered over the entire surface of the case. As it is received, the burr must be removed.

For example, a cutting tool, such as an end mill, may be configured to move up and down, and the end mill may be moved downward, or the position of the cutting tool may be fixed, and the case may be positioned at the cutting tool to process burrs through the cutting tool. When the burr of the case is removed, if a plurality of burrs are formed over the front of the case, they must be removed one by one while transferring the case, and in this process, where the burr is located by transferring a cutting tool or by transferring the case. Since the machining process must be consistent with the position of the cutting tool, troublesome, time-consuming, and low productivity problems occur.

In addition, in order to remove the burr, at least one of the cutting tool or the case must move up, down, left, right, and front and rear positions. Therefore, if the correct position is not set, burr cutting of the case is made less or As a result, the depth of the case was not smooth.

Therefore, the present invention is to solve the above problems, the middle plate having a plurality of cutting tools fixed to the pulley; A jig forming a penetrating seat; Bracket is fixed to the shaft is composed of a plurality of pulleys, to fix the middle plate and jig in order to the bottom and a certain height, install a plurality of brackets around the middle plate, and secures the belt around the pulley of the bracket, The pulley of each bracket and the pulley combined with the cutting tool are connected by a belt, and a burr removing device configured to rotate the shaft of one bracket by a motor is mounted, the metal case is seated and pressed to the jig seating portion, and the motor is rotated. This allows the burr to be removed quickly at once by rotating the cutting tool.
