Description

  The present invention relates to a workpiece processing method in a plate processing machine such as a turret punch press, a laser processing and a punching processing composite machine, and a plate processing machine used for carrying out the workpiece processing method.

  Conventionally, as an example of a plate material processing machine, a plate-shaped workpiece is loaded into a turret punch press, the workpiece is positioned at the origin position, and then the workpiece is moved in the X axis direction and the Y axis direction with respect to the processing position in the plate material processing machine. There is known a configuration in which a workpiece is processed by moving and positioning the workpiece, and then the workpiece is unloaded.

  FIG. 5 is a plan view of such a plate material processing machine described in Patent Document 1. As shown in FIG.

  This plate material processing machine has a processing machine body 110 provided with upper and lower turrets 111 at the center in the X-axis direction when two directions orthogonal to each other in the horizontal plane are defined as the X-axis direction and the Y-axis direction. A fixed work table 122 and a movable work table 123 are arranged on both sides in the X-axis direction of 110, and a rectangular plate-shaped work W loading device 160 and a processed work are carried out further outside of the fixed work table 122 in the X-axis direction. The apparatus 170 is arranged.

  The upper and lower turrets 111 provided rotatably are provided with a plurality of punches and dies, and the turret 111 indexes the punches and dies for processing the plate-like workpiece W with respect to the processing position 112. It can be positioned.

  The movable work table 123 is connected to a Y-axis carriage (carriage base) 125 so that the Y-axis carriage 125 and the movable work table 123 can be freely moved and positioned in the Y-axis direction. On the Y-axis carriage 125, an X-axis carriage 130 provided with a work clamping device 140 for clamping the work W is provided so as to be able to move and position in the X-axis direction. Therefore, the X-axis carriage 130 on which the work clamp device 140 is mounted can be moved and positioned at arbitrary positions in the X-axis direction and the Y-axis direction.

  A straight line parallel to the X-axis direction and a straight line parallel to the Y-axis direction passing through the machining position 112 are defined as an X-axis X1 and a Y-axis Y1, respectively, and the X-axis X1 and the Y-axis Y1 in an orthogonal coordinate system having the machining position 112 as an origin. The first quadrant E1, the second quadrant E2, the third quadrant E3, the fourth quadrant E4 are set in the counterclockwise direction when the four areas partitioned by the above are viewed from above, and the first quadrant E1 and the second quadrant E2 are set to the Y axis. Is located on one side of the direction (lower side in FIG. 5) and adjacent to each other along the X-axis direction, and the third quadrant E3 and the fourth quadrant E4 are placed on the other side in the Y-axis direction (upper side in FIG. 5). ) And adjacent to each other along the X-axis direction, the workpiece clamping device 140 has a side edge located on one side (lower side in FIG. 5) of the rectangular plate-like workpiece W in the Y-axis direction. It is arranged to clamp. Moreover, the carrying-out apparatus 170 which carries out the workpiece | work after a process outside is arrange | positioned in the 3rd quadrant E3 located in the other side (upper side in FIG. 5) of a Y-axis direction.

  Conventionally, the workpiece W is loaded from the loading device 160 onto the workpiece tables 122 and 123 located in the first quadrant E1, and the workpiece W is positioned at the origin, and then one side of the workpiece W (the lower side in FIG. 5). In this state, the Y-axis carriage 125 and the X-axis carriage 130 are moved, and the workpiece W is moved and positioned in the X-axis direction and the Y-axis direction with respect to the machining position 112. Then, the workpiece W is machined at the machining position 112. Then, the processed workpiece W moves to the third quadrant E3 and is delivered to the carry-out device 170. In addition, after the workpiece W is unloaded, the workpiece clamping device 140 is moved back to the first quadrant E1, which is the origin position, and then the next workpiece is loaded.

  The work W is loaded into the first quadrant E1 after returning the work clamp device 140 to the first quadrant E1, which is the origin position, when the work clamp device 140 is moving near the third quadrant E3. This is because the workpiece W cannot be carried into the first quadrant E1 due to an obstacle such as 125.

  That is, conventionally, after unloading the previous workpiece, the workpiece clamping device 140 moves to the origin position, and in that state, the next workpiece W is loaded into the new first quadrant E1 and the origin positioning of the next workpiece W is performed. The workpiece workpiece W is clamped by the workpiece clamping device 140 as one flow.

  However, in the conventional case, after the work clamping device 140 completes the work in the third quadrant E3 (delivery of the pre-processed work to the carry-out device), the work clamp device 140 moves from the work position in the third quadrant E3 to the diagonal position. Since the next workpiece W is loaded after waiting to move to a certain first quadrant E1, there is a problem that the loss time is increased and the movement time of the workpiece clamping device 140 is long. It was.

  This plate material processing machine is exemplified as a turret punch press, but is not limited to a turret punch press, and can be applied to a laser processing machine, a combined processing machine in which a laser processing machine and a punch press are combined, or the like. .

  As shown in FIG. 1, the plate material processing machine includes a processing machine main body 10 that performs main processing (processing such as product shaping and punching) on a plate-shaped workpiece (not shown) at a processing position 12; A final processing device 50 for performing final processing (processing such as cutting of the outer periphery of the product, cutting of the end material, and cutting of the product) with respect to the work after the main processing, and an unloading device 70 for carrying out the work after the final processing to the outside, In the horizontal plane with respect to the processing position 12 of the processing machine body 10, the work tables 21 to 23 on which the work is placed, the loading device 60 for loading the work to be processed on the work table 22, and the work loaded on the work table 22 And a workpiece movement / positioning device that moves / positions in the X-axis direction and the Y-axis direction orthogonal to each other.

  The workpiece moving / positioning device includes a Y-axis carriage 25 that can be moved and positioned in the Y-axis direction, an X-axis carriage 30 that is mounted on the Y-axis carriage 25 and can be moved and positioned in the X-axis direction, and the X-axis carriage 30. And a workpiece clamping device 40 that clamps one side edge of the workpiece along the X-axis direction. With this configuration, the workpiece clamped by the workpiece clamping device 40 mounted on the X-axis carriage 30 can be freely moved and positioned at arbitrary positions in the X-axis direction and the Y-axis direction.

  The upper and lower turrets 11 rotatably provided on the frame 15 of the processing machine body 10 are provided with a plurality of punches and dies, and the turrets 11 are provided with punches and dies for processing plate-like workpieces. Indexing positioning can be performed with respect to the processing position 12.

  A straight line parallel to the X-axis direction and a straight line parallel to the Y-axis direction passing through the machining position 12 are defined as an X-axis X1 and a Y-axis Y1, respectively, and an X-axis X1 and a Y-axis Y1 of an orthogonal coordinate system having the machining position 12 as an origin. The four divided areas are set to the first quadrant E1, the second quadrant E2, the third quadrant E3, and the fourth quadrant E4 in the counterclockwise direction, and the first quadrant E1 and the second quadrant E2 are in the Y-axis direction. Is located on one side (lower side in FIG. 1) and adjacent to each other along the X-axis direction, and the third quadrant E3 and the fourth quadrant E4 are on the other side in the Y-axis direction (upper side in FIG. 1). The workpiece clamping device 40 is located on one side in the Y-axis direction (lower side in FIG. 1) of the rectangular plate-shaped workpiece W (see FIG. 3). It is arranged to clamp the located side edges.

  Further, the final processing device 50 and the carry-out device 70 are arranged in a third quadrant E3 located on the other side in the Y-axis direction (upper side in FIG. 1). Further, the fourth quadrant E4 adjacent to the third quadrant E3 is a workpiece carry-in quadrant of the next workpiece, and the carry-in device 60 is arranged so that the work can be loaded onto the work table 22 in the fourth quadrant E4. .

  In addition, the work tables 21 to 23 are generally constituted by a brush table having an upper surface as a pass line having a constant height, but the next processing carried into the work table 22 in the fourth quadrant E4. When the workpiece is clamped by the workpiece clamping device 40, only the region located under the workpiece clamping device 40 (hatched portion in FIG. 1) is configured as a lowering table 24 that can be lowered below the workpiece pass line. Has been.

  FIG. 2 shows the difference between the height when the lowering table 24 is lowered and the height of the other work table 22 (pass line PL).

  When clamping the workpiece carried into the first quadrant E1, the workpiece clamping device 40 can clamp the workpiece in the absence of the workpiece table 22 below, so there is no problem in clamping the workpiece. When clamping the work carried in the fourth quadrant E4 as in the present embodiment, the work must be clamped under the condition that the work table 22 of the first quadrant E1 exists below.

  As shown in FIG. 2, the workpiece clamping device 40 is configured to clamp the workpiece between the lower claw 41 and the upper claw 42, but when the workpiece clamping device 40 moves on the workpiece table 22, the workpiece clamping device 40 When the device 40 rides on the brush of the work table 22 and the lower claw 41 rises to the height of the pass line PL, and the workpiece is clamped at that height, the workpiece and the lower claw 41 hit and cannot be clamped. . Therefore, it is necessary to perform clamping with the clamp base including the lower pawl 41 lowered.

  Therefore, in the plate material processing machine according to the present embodiment, a part of the work table 22 corresponding to the lower region of the work clamp device 40 is lowered to a height at which the clamp base of the work clamp device 40 is lowered and the lower claw 41 and the work do not hit when necessary. It is configured as a descending table 24 that can be retracted. Therefore, since it is the same state as the case where the work table 22 does not exist below the work clamping device 40 when the work carried in the first quadrant E1 is clamped, there is no problem in clamping the work.

  For example, when the height of the clamp base of the work clamping device 40 must be lowered by the dimension H1 in order to clamp the work on the work table 22, the lowering table 24 is lowered by a dimension H2 that is slightly larger than the dimension H1. To. By doing so, it becomes possible to smoothly adjust the height of the lower claw 41 of the work clamping device 40 to a height at which the work can be reliably clamped without receiving the resistance of the brush in the lower region. Note that, during normal times other than clamping, the lowering table 24 is raised to the height of the pass line PL. The lowering table 24 is raised and lowered by a cylinder mechanism 24a or the like.

  Further, as shown in FIG. 3, a locating pin 45 and a drawing pad 47 are provided in order to position the rectangular plate-shaped workpiece W carried into the fourth quadrant E <b> 4 at the stage of clamping by the workpiece clamping device 40. . The locate pin 45 is projected and retracted with respect to the pass line of the work W by an actuator disposed on the lower side of the work table 22, and can position the work W when it is in a state of protruding from the pass line. . Further, the attracting pad 47 is capable of pressing the work W against the locating pin 45 or the positioning wall of the work clamping device 40 by being attracted to the upper surface of the work W by an attractive force or a magnetic force.

  Next, the flow of the workpiece W will be described with reference to FIGS. 3 and 4A.

  The workpiece W is loaded from the loading device 60 onto the workpiece table 22 in the fourth quadrant E4 as indicated by an arrow S1. The loaded workpiece W is positioned at the origin and then clamped by the workpiece clamping device 40. In the clamped state, the X-axis carriage 30 and the Y-axis carriage 25 are operated to move the X-axis relative to the machining position 12. The processing machine body 10 performs the main processing at the processing position 12 while being moved and positioned in the direction and the Y-axis direction.

  When the workpiece W is clamped by the workpiece clamping device 40, the lowering table 24 can be lowered to a height at which the workpiece does not interfere with the lower claw 41 (FIG. 2) of the workpiece clamping device 40 and does not interfere with the workpiece clamping. After clamping, it returns to the normal pass line height.

  The workpiece W after the main machining is moved to the third quadrant E3 while being clamped by the workpiece clamping device 40, and is finally machined by the final machining device 50. Then, the workpiece W after the final machining is transferred from the workpiece clamping device 40 to the unloading device 70 as indicated by an arrow S2 and unloaded to the outside.

  Here, the fourth quadrant E4 adjacent to the third quadrant E3 is the workpiece carry-in quadrant of the next workpiece, and when the final machining is performed on the previous workpiece in the third quadrant E3, or after the final machining, the workpiece clamp When the pre-worked workpiece clamped by the device 40 is transferred to the carry-out device 70, the next work W is carried onto the work table 22 in the fourth quadrant E4, which is the work carry-in quadrant.

  Then, the work clamp device 40 that is released after the pre-work workpiece is transferred to the carry-out device 70 can be clamped from the work position A2 in the third quadrant E3 to the work W carried into the fourth quadrant E4. In this state, the next workpiece W is positioned at the origin, and then the workpiece C is clamped by the workpiece clamping device 40, and the main machining is started.

  In addition, the origin positioning of the next workpiece W carried on the work table 22 in the fourth quadrant E4 is performed by locating the side edge along the Y-axis direction of the workpiece W using the drawing pad 47 attracted to the upper surface of the workpiece W. 45 and pressing the side edge along the X-axis direction against the positioning wall of the work clamp device 40.

  According to the machining method of this embodiment, since the next workpiece W is carried in before the workpiece clamping device 40 engaged in the work in the third quadrant E3 is released, the loss time is reduced. Can do. Further, since the next workpiece is carried into the fourth quadrant E4 adjacent to the third quadrant E3 where final machining and unloading are performed, the workpiece clamping device 40 is returned from the final work position A2 near the third quadrant E3 to the origin position A1. The travel time can be reduced.

  For example, as shown in FIG. 4B, in the conventional work flow, the work W is moved to the first quadrant E1 after the work clamp device 40 is moved to the origin position A3 of the first quadrant E1. The loss time was large because it was carried in. In addition, since the work clamp device 40 that has finished the work at the final work position A2 in the third quadrant E3 is returned from the third quadrant E3 to the origin position A3 of the first quadrant E1 that is in a diagonal position, the movement distance is increased. Only the travel time was getting longer.

  According to the machining method of the above-described embodiment of the present invention, these problems can be solved, the tact time from carrying in one workpiece W to carrying it out can be shortened, and productivity can be improved.

  In addition, according to the machining method of the embodiment of the present invention, it is possible to reliably perform the origin positioning of the next workpiece W with a simple configuration.

  Further, when the work workpiece W conveyed on the work table 22 in the fourth quadrant E4 is clamped by the work clamp device 40, the work table (lowering table 24) in the lower region of the work clamp device 40 is lowered. Therefore, the workpiece clamping device 40 can be lowered smoothly without being obstructed by the workpiece table in the lower region, and the next workpiece can be reliably clamped by the workpiece clamping device 40.
