Description

  This invention repeats the operation of selecting a set that matches a forging process for forming a workpiece from a plurality of dies and a plurality of punches, and performs a plurality of forging processes and cutting processes, thereby improving processing accuracy. The present invention relates to a turret forging device that reduces costs.

  Conventionally, as a type of press machine, there is a turret punch press that punches a thin sheet metal sheet without moving the sheet metal. This is because a large number of molds having different shapes are arranged in a circular or fan-shaped mold holder called a “turret”, and a predetermined position on a material (workpiece) is determined with a predetermined mold by NC control. Punching and forming. It is possible to punch a sheet metal into an arbitrary shape by continuously punching general-purpose dies (overtaking, nibbling), which is suitable for high-mix low-volume production.

  In this press machine, the press position is fixed, and the processing location is determined by clamping the sheet metal material and moving it on the XY table. For example, processing of up to 5 scale × 10 scale material (1524 mm × 3048 mm) or 4 scale × 8 scale material (1219 mm × 2438) is considered, but the installation location must be wide. Brushes and rollers are provided on the table to facilitate the movement of the sheet metal. Once the mold is set, basically no care is required until it is worn. Also, because of the nature of the machine, manpower can only be involved when the machine is stopped, so there is little risk of occupational accidents. Molds are proprietary standards by manufacturers and are not interchangeable except for some special cases. Thin plate can be processed automatically. On the other hand, it is unsuitable for thick plate processing, deep drawing and forging. Molding is limited to the level that fits in the mold size, and full-scale bending requires the use of a press brake. In addition, dedicated software for creating an NC control program is required. The punched product is discharged without being cut off and connected by the metal sheet and the micro joint. Separate product separation work is required.

  Conventionally, a forging method in which a workpiece is conveyed by a conveying device between a plurality of dies is known (see, for example, Patent Document 1 (FIG. 1) and Patent Document 2 (FIG. 1)).

It is a forging device that repeats the operation of selecting one set that matches the above and performs a plurality of forging processes and cutting processes.

(Main part configuration of the turret forging device 1)
The structure of the main part of this turret forging device 1 is shown in FIGS. FIG. 4 is a perspective view of the main part of the turret forging device 1, and FIG. 5 is a block diagram of the main part of the turret forging device 1. The turret forging device 1 includes a die starlet unit 10, a die rotation mechanism unit 12, a punch turret unit 20, a side pressure mechanism unit 30, a cutting mechanism unit 40, a parts handler 70, a die clamp mechanism unit 80, and a punch clamp mechanism unit 90. The switching mechanism 50 and the control device 60 are provided between the die set (upper) 110 and the die set (lower) 111.

  Command data is created on a PC or tablet 100 and an operation simulation is performed, and then sent to a control device 60 such as a sequencer as batch processing data wirelessly or by wire. The control device 60 performs wired transmission (bidirectional), and the command data. The die starlet part 10, the punch turret part 20, the side pressure mechanism part 30, the cutting mechanism part 40, the part handler 70, the die clamp mechanism part 80, the punch clamp mechanism part 90, and the switching mechanism part 50 are controlled based on the above.

  This turret forging device 1 has a disc-shaped or fan-shaped turret portion, and includes a holder for holding at least two dies 11 or punches 21 having different shapes, and enables forward and reverse rotation. It is a configuration. The holder has a function of inserting the material into the die 11 and carrying out the processed product out of the turret forging device 1 so that the processed product knocked out by the press machine 2 after the forging is grasped and held in the air. An empty holder can also be provided in order to secure a space for this. The turret forging device 1 is driven by an electric motor and has an electromagnetic brake. The die 11 and the punch turret part 20 are set to symmetrical positions with respect to the die set center when viewed from the upper surface of the press machine 2 so as to avoid mutual interference. The rotational positioning may be forcibly stopped by protruding a pin or the like.

  The die starlet unit 10 includes at least two or more dies 11 each having a forming hole for a forged product formed by forging, and a die rotating mechanism unit 12 that rotates the holder and the die 11. The die rotation mechanism unit 12 appropriately adjusts the processing position of the workpiece so that the cutting mechanism unit 40 and the side pressure mechanism unit 30 can easily perform the processing operation by rotating. Further, it is possible to perform free forging by repeatedly forging while rotating only one type of die with the die rotating mechanism unit 12 using at least one type of punch for main forming. The punch turret unit 20 includes at least two punches 21 and a holder that are arranged to face the die 11.

  The side pressurization mechanism unit 30 changes the pressurization direction from the pressurization axis direction of the press machine 2 to the orthogonal direction in order to plastically deform the forged product from the direction orthogonal to the pressurization axis of the press machine 2. And a pressurizing mechanism such as a cam slide for moving in the vertical direction, the left-right direction, and the front-rear direction in alignment.

A die clamping mechanism 80 for fixing the punch 21 and a punch clamping mechanism 90 for fixing the punch 21 and the holder during forging are provided. Each clamp mechanism fixes at least two points by hydraulic pressure or pneumatic pressure, and reliably stops the movement in the vertical direction, the horizontal direction, and the rotational direction. The switching mechanism unit 50 enables or disables the side pressurizing mechanism unit 30 by moving on the linear motion slide rail 51 by an electric motor, pneumatic pressure, or hydraulic pressure.

  The main forming direction and position in the turret forging device 1 is the pressurizing axis direction of the press machine 2, and the position is the pressurizing axis of the press machine 2, and the side pressurizing mechanism 30 and the cutting mechanism section. The direction and position of the sub-molding in which 40 operates is a direction orthogonal to the pressing axis direction of the press machine 2, and the position is specified by the user. A plurality of forging processes controlled by the control device 60 is performed by forging the press machine 2 with a pair of punches 21 and dies 11, and then rotating both or one of the punch turret part 20 and the die starlet part 10 to produce another punch. This is realized by performing the forging process by setting 21 and the die 11 as a set at least twice.

  The rotation centers of the punch turret unit 20 and the die starlet unit 10 are arranged at symmetrical positions with respect to the center of the pressing axis of the press machine 2 when the press machine 2 is viewed from directly above in order to avoid mutual interference. Moreover, the punch turret part 20 and the die starlet part 10 enable forward and reverse rotation. Next, a plurality of forging steps for the universal joint yoke made of aluminum alloy A6061 will be described in detail with reference to FIGS.

(First step)
The first step is preforming and will be described with reference to FIG. 6 (a) is a perspective view of the turret forging device 1, FIG. 6 (b) is a plan view of the turret forging device 1, and FIG. 6 (c) is a diagram showing a material shape and a processed product shape after processing. (D) is a figure which shows the 1st process die | dye and the 1st process punch. The operation of the first step will be described.

Operation 1:
The punch turret 20 rotates and stops at the position of the empty holder. Do not clamp. As a result, the punch is not set on the pressure axis of the press machine 2. This is to avoid the punch when the parts handler 70 is operated in the operation 3 because it interferes if the punch is directly above the first process die.
Operation 2:
The die starlet part 10 rotates and stops at the position of the first process die and clamps. Sensing is performed using a photoelectric center or the like so as to surely come to the pressing axis of the press machine 2. In addition, when the operation 1 and the operation 2 do not interfere with each other, the operation is programmed to operate simultaneously.
Operation 3:
The material received from the material shooter (not shown) by the parts handler 70 is set in the cavity of the first process die.
Operation 4:
The punch turret rotates, stops at the position of the first process punch, and clamps. In addition, it is sensed by the photoelectric center or the like whether or not the operations 3 and 4 are reliably completed at a predetermined position.
Operation 5:
The control device 60 senses a sensing OK signal that the positional relationship among the punch turret unit 20, the die starlet unit 10 and the material is in a machining start state, and sends a signal to the control device of the press machine 2 for the first process. Press for the stroke entered in advance. Thereby, the turret forging device 1 and the press machine 2 operate in synchronization. Since the first process die is used in common with the second process, the knockout function of the press machine 2 for taking out the processed product from the die is not used at the end of the first process.

(Second step)
The second step is main molding and will be described with reference to FIG. 7 (a) is a perspective view of the turret forging device 1, FIG. 7 (b) is a plan view of the turret forging device 1, and FIG. 7 (c) is a diagram showing the shape of a processed product before and after processing. These are figures which show the 2nd process die and the 2nd process punch. The second process die is the same as the first process. The operation of the second step will be described.

Step 6:
The clamp of the punch turret part 20 is released, the punch turret part 20 rotates, stops at the position of the punch for the second step, and is clamped. Note that the second step is a common die and the same die as the first step is used, so the die starlet unit 10 is left as it is.
Step 7:
The control device 60 senses a sensing OK signal that the punch turret unit 20 is in the processing start state, and sends a signal to the control device of the press machine 2 to perform press processing for the stroke input in advance for the second step. .
Operation 8:
The punch turret 20 rotates and stops at the position of the empty holder. As a result, the punch is not set on the pressure axis of the press machine 2. Do not clamp. This is to avoid the punch when the parts handler 70 is operated in operation 9 because it interferes with the punch being directly above the second process die.
Step 9:
The control device of the press machine 2 knocks out the workpiece from the second process die to a predetermined height at which the workpiece is not restrained by the die, that is, a height at which the parts handler 70 can handle the workpiece freely with no load. Note that operations 8 and 9 are simultaneous operations.
Operation 10:
The workpiece is grasped by the parts handler 70 and held in the air at a position where it does not interfere with both rotating turret portions in preparation for the next process. The interference check has been verified in advance on a PC (or tablet).

(Third step)
The third step is simultaneous punching of two holes: molding by the side pressure mechanism 30 using a cam slide or the like, and will be described with reference to FIG. 8 (a) is a perspective view of the turret forging device 1, FIG. 8 (b) is a plan view of the turret forging device 1, FIG. 8 (c) is a diagram showing the shape of a processed product before and after processing, and FIG. FIG. 8E is a view showing a third process die and a third process punch, and FIG. The operation of the third step will be described.

Operation 11:
The clamp of the die starlet part 10 is released, and the die starlet part 10 rotates and stops at the position of the third process die. Clamp.
Operation 12:
For example, the switching mechanism 50 is moved straight along the straight slide rail 51 by air pressure, and stops at a position where the side pressure mechanism 30 becomes effective. Clamp. The switching mechanism 50 is positioned by sensing with a photoelectric sensor or the like. Operation 11 and operation 12 operate simultaneously. The switching mechanism 50 may be forcibly stopped with a stopper or a pin. Here, the side pressurization mechanism unit 30 becomes effective when the press machine 2 enters the pressurization operation and the axis of the switching mechanism unit 50 reaches the side pressurization mechanism until the press bottom dead center is reached. This is a state in which the side pressure mechanism unit 30 can be pressurized by the switching mechanism 50 by moving on the linear slide rail 51 to a position just above the axis of the unit 30.
Operation 13:
The processed product held by the parts handler 70 is set in the cavity of the third process die. Here, the cavity for inserting the processed product of the third step die is enlarged by a clearance (about 0.1 mm) so that the processed product can be inserted without resistance. A hole that is larger than the clearance (about 0.05 mm) is opened.
Operation 14:
The punch turret portion 20 rotates and stops at the position of the third process punch. Clamp. The operation 14 operates after the operation 13 and is positioned by sensing using a photoelectric sensor or the like.
Operation 15:
When there is no problem in positioning the die starlet unit 10, punch turret unit 20, processed product, and switching mechanism unit 50, the control device 60 senses a signal from the photoelectric center or the like and sends the signal to the control device of the press machine 2. Then, press working is performed for the stroke input in advance for the third step.
Operation 16:
The press slide of the press machine 2 descends, and the switching mechanism unit 50 comes into contact with the cylinder of the side pressurization mechanism unit 30 to pressurize the two side pressurization mechanism units 30 by the cam slide or the like. Operates in a direction perpendicular to the pressure axis and punches two holes simultaneously. At this time, the punch for the third step is adjusted so that the side pressurizing mechanism 30 operates while the hydrostatic pressure that presses the processed product from above is applied to the punch for the third step.

[Draining method for waste]
In the punching operation in the operation 16, a punching residue is generated. As shown in FIG. 8 (e), this is continuously processed by providing a discharge hole below the third step die or directly below the die in the die starlet part 10 or just below the die in the die set (lower) 111.

  By exchanging the punches of the side pressurizing mechanism 30, not only punching but also a hollow part or the like can be formed in a part of the forged product. Further, after setting a hole punching die on the die rotation mechanism unit 12 and punching one hole by the side pressurization mechanism unit 30 by one cam slide or the like, the die rotation mechanism unit 12 is rotated by 180 ° to 2 The second punching operation can also be performed by the second press working operation. In addition, the operation timing of each of the side pressurizing mechanism units 30 can be changed by changing the lengths of the cylindrical portions of the two switching mechanism units 80. For example, it is applied when the plate thickness of punched holes × 2 places (in the case of the first invention) is larger than the width of the punched waste discharge space. In addition, the punches of the third and fourth steps are shared, and are used only to press the workpiece from above with a spring or a gas cushion to act on the hydrostatic pressure. Does not occur. Only plastic deformation as punching is performed.

(4th process)
The fourth step is precision drilling: cutting with a drill, which will be described with reference to FIG. 9 (a) is a perspective view of the turret forging device 1, FIG. 9 (b) is a plan view of the turret forging device 1, FIG. 9 (c) is a diagram showing the shape of a processed product before and after processing, and FIG. It is a figure which shows the die for 4th processes, and the punch for 4th processes. The operation of the fourth step will be described.

Operation 17:
When the press slide of the press machine 2 that has reached the bottom dead center rises, the side pressure mechanism 30 is unloaded and the side pressure shaft returns to the position before processing.
Operation 18:
When the air pressure of the switching mechanism unit 50 is reduced, for example, the switching mechanism unit 50 returns to the position where the switching mechanism unit 50 is invalidated on the linear guide rail 51 by a spring force.

Operation 28:
The cutting guide hole on the side of the fourth process die is sensed by a photoelectric center or the like while stopping at the bottom dead center of the press slide. If the position is OK, it remains as it is, but if there is a problem, the cutting mechanism 40 is moved in the vertical and horizontal directions to position it. Although not shown in the drawings, the vertical and horizontal movement mechanisms are based on an electric motor or the like.
