Fig.

With reference to these figures, the transfer press apparatus and method for molding a vehicle body part according to the present invention can automatically produce a body part with a roll type coil with a compact and efficient structure, Can be improved.

That is, according to the present invention, a coil wound in a roll type is unfolded and cut into a plate of a unit size, and then the cut plate is pressed to form a desired body part. Since the body part at this time may be various shapes that can be applied to various positions of the vehicle, the illustration of its specific shape is omitted. However, all products that can be made by pressing a flat plate material should be within the scope of the present invention.

1, a transfer pressing apparatus for forming a body part according to the present invention includes a coil feeding unit 110, a shearing unit 120, a loading unit 130, a multi-joint robot 140, A pressing unit 150, a pressing unit 160, a blowout unit 170, and a controller 190 for controlling them.

The coil feeding unit 110 rotatably supports a coil wound in a roll type, and serves to supply the coil to the process line by rotational motion. Here, the process line refers to a line by each process that follows the coil feeding unit 110.

The coil feeding unit 110 includes a coil mounting portion 111, a rotation driving portion 112, a guide arm 113, a coil replacing portion 114, a coil mover 115, a spreading roller 116, (117) and a coil front end chucking portion (118). The configuration of the coil feeding unit 110 will be described.

The coil mounting portion 111 is a portion where the coil is rotatably mounted. The coil can be rotatably mounted on the coil mounting portion 111 at its central portion. A coil replacement unit 114 is provided in the coil feeding unit 110 so that the coil can be easily mounted and replaced in the coil mounting unit 111. [

The coil replacement part 114 is disposed around the coil mounting part 111 and serves to replace the coil while transmitting the coil to the coil mounting part 111 while approaching or separating from the coil mounting part 111. [

The coil replacement portion 114 may include a coil loading portion 114a on which the coil is loaded and a forward and backward driving portion 114b for driving the coil loading portion 114a in the forward and backward directions.

Since the coil is a massive structure, the coil is loaded on the coil loading portion 114a, and then the coil is moved to the replacement position using the forward / backward driving portion 114b. Then, the coil is replaced using a crane or the like .

The rotation driving part 112 is connected to the coil mounting part 111 and serves to rotationally drive the coil mounting part 111. The rotation driving unit 112 may be applied to a cylinder structure, a motor structure, or the like. Therefore, detailed illustration of the rotation driving unit 112 will be omitted.

The guide arm 113 is disposed around the coil mounting portion 111 and serves to guide the coil to be unwound while being rotated by the coil mounting portion 111.

An arm driving part 113a for driving the guide arm 113 is connected to the guide arm 113 so that the guide arm 113 can contact the coil. When the guide arm 113 guides the coil unwound from the coil mounting portion 111, a stable coil unwinding process can be expected and a safe operation can be realized.

The coil mover 115 is disposed between the shearing unit 120 and the coil mounting unit 111 and serves to move the coil unwound from the coil mounting unit 111 to the shearing unit 120. Thus, a power unit can be connected to the coil mover 115.

The spread roller 116 is disposed between the coil mover 115 and the shearing unit 120 and serves to spread the coil toward the shearing unit 120 in a flat manner. Accordingly, a plurality of spreading rollers 116 may be spaced apart from each other. As shown in the drawing, a plurality of spreading rollers 116 are arranged vertically so that a coil passing between the spreading rollers 116 spreads flatly.

The coil rear end chucking portion 117 is disposed between the spreading rollers 116 and the coil mover 115 and serves to chuck the rear end portion of the coil to be moved. The chucking portion 118 of the coil front end portion is disposed between the spreading rollers 116 and the shearing unit 120 and serves to chuck the front end portion of the coil to be moved.

When the shearing unit 120 is operated, the coil front end chucking portion 118 and the coil rear end chucking portion 117 sequentially chuck the coils. Therefore, it is possible to cut the correct position of the coil. Of course, since the coil rear end chucking portion 117 and the coil front end chucking portion 118 do not necessarily have to be applied, a device without these should also fall within the scope of the present invention.

A fixed lower guide 181, a rotatable upper guide 182, and a guide actuator 183 may be further disposed around the coil mover 115.

The fixed type lower guide 181 is disposed between the coil mounting portion 111 and the coil mover 115 and serves to guide the coil toward the coil mover 115. The rotatable upper guide 182 is fixed to the stationary lower guide 181 and serves to guide the coil together with the stationary lower guide 181.

The guide actuator 183 is connected to the rotatable upper guide 182 and rotatably drives the rotatable upper guide 182. Since the rotary type upper guide 182 can be rotated by the guide actuator 183, the rotary type upper guide 182 can guide the coil to be released together with the stationary lower guide 181 in a post process.

The shearing unit 120 is disposed behind the process of the coil feeding unit 110 and serves to cut the supplied coil into unit sizes.

Although the coil may be bent through the shearing unit 120, in the present invention, the shearing unit 120 cuts the continuous coil into a unit size. After passing through the shearing unit 120, a sheet material of a certain size is formed.

The stacking unit 130 is a place where a sheet material of a unit size cut by the shearing unit 120 is stacked.

The loading unit 130 may be equipped in that the pressing operation requires a somewhat longer time than the sharing operation. It is preferable that a plurality of stacking units 130 are provided.

The articulated robot 140 is disposed around a plurality of the stacking units 130 and serves to handle and supply the sheets on the stacking unit 130, that is, the transfer unit 150. Of course, instead of the articulated robot 140, corresponding structures, i.e., a conveyor system, may be applied.

The transfer unit 150 is disposed adjacent to the articulated robot 140 and feeds the plate material to the press processing unit 160 that is located downstream of the process, that is, substantially progressing the molding operation.

A plate material centering unit 184 may be provided around the transfer unit 150. The plate material centering portion 184 is disposed movably around the transfer unit 150 and serves to center the plate material loaded on the base mold 161. [

When the plate material centering portion 184 is applied as in the present embodiment, the plate material centered in the correct position can be supplied to the press processing unit 160, so that the quality of the product to be press processed can be improved.

The press working unit 160 is disposed behind the transfer unit 150 and presses the plate material transferred from the transfer unit 150 into a body part.

The press processing unit 160 includes a base die 161 on which a plate material is placed, a press die 162 disposed on the upper portion of the base die 161, a press die 162 connected to the press die 162, A mold up / down driving unit 163 for up / down driving, and a moving alignment bar 165.

At this time, the moving alignment bar 165 is disposed around the base die 161 and is movable to the base die 161, and the plate loaded on the base die 161 is moved to the correct position And includes a plurality of aligners 164 that align.

In other words, since the moving aligning bar 165 is moved toward the base metal mold 161, a plurality of aligners 164 can align the plate material to the correct position, so that the press metal mold 162 always presses the right position of the plate material Therefore, it is possible to improve the quality of the product.

The take-out unit 170 is disposed at the rear of the process of the press-working unit 160, and is a place where the press-processed body parts are taken out.

The controller 190 includes a coil feeding unit 110, a shearing unit 120, a articulated robot 140, a transfer unit 150, a pressing unit 160, a takeout unit 170, a guide actuator 183 ) And the plate material centering 184 can be automatically controlled.

The central processing unit 191 includes the coil feeding unit 110, the shearing unit 120, the articulated robot 140, the transfer unit 150, the pressing unit 160, the blowout unit 170, It may be one of various computer processors that can be industrially applied to automatically control the operation of the guide actuator 183 and the plate material centering 184 section.

The memory 192 (MEMORY) is connected to the central processing unit 191. The memory 192 is a computer-readable recording medium that may be installed locally or remotely and may be any of various types of storage devices such as, for example, random access memory (RAM), ROM, floppy disk, hard disk, May be at least one or more memories.

A support circuit 193 (SUPPORT CIRCUIT) is coupled with the central processing unit 191 to support the typical operation of the processor. Such a support circuit 193 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

In this embodiment, the controller 190 includes a coil feeding unit 110, a shearing unit 120, a multi-joint robot 140, a transfer unit 150, a pressing unit 160, a blowout unit 170, The control unit 183, and the plate material centering unit 184, and this series of processes and the like can be stored in the memory 192. Typically, software routines may be stored in memory 192. The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

Hereinafter, a transfer pressing method for forming a body part will be described.
