  FIG. 2 is a side view of the key pile processing apparatus according to the embodiment of the present invention. FIG. 3 is a top plan view of the key pile processing apparatus according to the embodiment of the present invention.

  As shown in FIG. 2, the holding unit 10 includes a holding plate 12 and a clamp unit 14 that sandwich and fix the key 100 from above. The clamp portion 14 includes a clamp lever 14 a and fixes the key 100 and the holder 60 by screwing the screw portion 14 b into the screw portion 25 b of the Y moving stage 25. In addition, a coil spring 16 is provided for urging the holding plate 12 in a direction away from the Y moving stage 25 to facilitate insertion and removal of the key 100.

  A through hole 12 a is formed at the center of the holding plate 12, and the clamp portion 14 screws the screw portion 14 b into the screw portion 25 b of the Y moving stage 25 through the through hole 12 a. The screw portion 14 b is screwed into the screw portion 25 b through the inner diameter of the coil spring 16.

  The clamp lever 14a and the screw portion 14b are integrally formed, and the screw portion 14b is screwed into the screw portion 25b of the Y moving stage 25 by rotating the clamp lever 14a. The key 100 is sandwiched between the holder 60 and the holding plate 12 set in the set groove 25 a of the Y moving stage 25. Thereby, the key 100 can be easily clamped to the Y moving stage 25. Further, when the clamp lever 14a is rotated to loosen the screw portion 14b, the holding plate 12 is urged upward by the urging force of the coil spring 16, thereby releasing the clamp, and the key 100 can be easily attached and detached. It becomes possible.

(Key mountain position setting unit 20)
The key crest position setting unit 20 is roughly configured by an X movement stage 21 that can be slid on the base board 50 and a Y movement stage 25 placed on the X movement stage 21. As shown in FIG. 2, the X moving stage 21 is guided on the base board 50 so as to be slidable in the longitudinal direction of the key 100 (longitudinal direction of the blade portion, X direction).

  The X moving stage 21 is guided on the base board 50 so as to be slidable in the longitudinal direction of the key 100 (longitudinal direction of the blade portion, X direction). The guide in the X direction is a key mountain height setting to be described later. It can be performed by the part 30 and the press working part 40. That is, the holding unit 10 (key mountain position setting unit 20) is disposed between the press working unit 40 and the key mountain height setting unit 30. As a result, the guide in the X direction can be configured on the base board 50 with a simple structure.

  The Y moving stage 25 is placed on the X moving stage 21 and is movable in the Y direction orthogonal to the longitudinal direction (X direction) of the key 100. The Y moving stage 25 can be moved in the Y direction by a guide portion (not shown) formed on the X moving stage 21, and by a biasing means in the Y direction (biasing spring 26 shown in FIG. 4), It is always biased in the direction of the key mountain height setting unit 30. Further, a contact surface 27 that is always in contact with the cam member 34 that defines the key peak height by the biasing means in the Y direction is formed on the key peak height setting portion 30 side of the Y moving stage 25. The contact surface 27 is formed over the necessary width in the X direction so that the contact surface 27 always contacts the cam member 34 even if the Y moving stage 25 moves in the X direction.

  As described above, the Y moving stage 25 is formed with the set groove 25a for setting the holder 60, the screw portion 25b into which the screw portion 14b of the clamp portion 14 is screwed.

  The X moving stage 21 can move in the X direction together with the Y moving stage 25. However, as shown in FIGS. 1, 3 and the like, this means that the holding unit 10 (key mountain position setting unit 20) is moved in the X direction. This is performed by operating the mountain position setting lever 22 that moves the position to the X position and fixes the position in the X direction. As shown in the cross section of FIG. 2, the mountain position setting lever 22 is rotatably supported with a fulcrum 51 provided on the base board 50 as a fulcrum. By operating the lever 23 of the knob 23, the mountain position setting lever 22 can be rotated with the fulcrum 51 as a fulcrum, and the X moving stage 21 can be slid in the X direction via the action part 22a.

  As shown in FIGS. 2 and 3, the pitch plate 24 is mounted on the base board 50. The pitch plate 24 is a plate for setting the formation position in the longitudinal direction of the key pile (longitudinal direction of the blade portion 100b, X direction, see FIG. 3), and the X direction of the press working portion 40 and the holding portion 10 is set. The relative position can be changed and functions as an exchangeable positioning member for setting a plurality of key mountain positions. The pitch plate 24 is provided with a plurality of code holes 24a for setting the formation positions of the key ridges as positioning holes. A projection 23a formed at the lower portion of the knob portion 23 is fitted into the cord hole 24a, whereby the peak position setting lever 22 is locked at a predetermined key peak position.

  A plurality of plates are prepared for the pitch plate 24 based on various key codes. The user can easily replace and mount the pitch plate 24 on the base board 50 by fitting the mounting holes 24b of the pitch plate 24 into protrusions (not shown) on the base board 50.

  The mountain position setting lever 22 can process a desired key mountain based on the key code by sequentially moving the lever position according to the code hole 24a of the pitch plate 24. Further, the mountain position setting lever 22 can further slide the X moving stage 21 beyond the position where the key mountain is formed. The position of the crest position setting lever 22 shown in FIG. 3 shows a state in which the X moving stage 21 is slid largely to the front side in the X direction beyond the processing range for forming the key crest. In this way, the X movement stage 21 can be slid and moved greatly beyond the processing range for forming the key pile, so that the key 100 can be easily attached and detached.

(Key mountain height setting unit 30)
The key pile height setting unit 30 is configured such that a height setting base 32 is placed and fixed on a base board 50, and a cam member 34 for defining the key pile height is mounted on the height setting base 32. The cam member 34 has a cam surface 34d for setting a plurality of key peak heights, and functions as a key peak height setting member that is replaceably attached to the key peak height setting portion.

  The height setting base 32 is fixed to a predetermined position on the base board 50 by bolts or the like. The height setting base 32 is directly fixed to the base board 50 with bolts or the like because it directly receives a reaction force during press working. The height setting base 32 is formed with a slit portion 32 a for mounting the cam member 34. Further, a shaft hole 32b into which the shaft 36 serving as the rotation center of the cam member 34 attached to the slit portion 32a is inserted is formed.

  The cam member 34 has a plate-like ring shape, and is configured such that a lever 34a for rotating operation is formed integrally with a part thereof. A central hole 34b serving as a rotation center is formed at the center of the cam member 34. By inserting the shaft 36 into the center hole 34b, it becomes a rotation center at the time of the rotation operation.

  FIG. 4A is a side view of the key pile processing apparatus showing only a main part showing a state before pressing with the key set in the holding portion, and FIG. 4B shows pressing the set key. It is a side view of the key pile processing apparatus which illustrated the case where it is carrying out.

  As shown in FIG. 4A, a stepped cam portion 34 c is formed on the outer peripheral portion of the cam member 34. Each cam portion 34c has a stepped cam surface 34d formed at a predetermined distance from the center along the circumferential direction. The distance Y1 from the center to the cam surface 34d of each cam portion 34c is formed in stages so as to be set according to the key code.

  As shown in FIG. 4A, when the cam member 34 is set at a certain position, the distance Y1 from the center of the cam member 34 to the cam surface 34d and the distance Y2 from the cam surface 34d to the processing surface of the key are set. . The cam member 34 can be rotated by operating the lever 34a. Thereby, the position of the processed surface of the key can be set according to the key code of the key to be manufactured (duplicated).

  The cam member 34 is prepared with a cam surface 34d corresponding to various key codes so as to be compatible with many key codes, and can be replaced as appropriate. That is, the shaft 36 shown in FIG. 3 is pulled out, the desired cam member 34 is set in the slit portion 32a of the height setting base 32, and the shaft 36 is again inserted into the shaft hole 32b through the center hole 34b, thereby being rotatable. It can be mounted on the height setting base 32 in a state.

  As shown in FIGS. 4A and 4B, the key mountain position setting unit 20 is always urged in the direction of the key mountain height setting unit 30 by the urging spring 26. Since the contact surface 27 of the key mountain position setting unit 20 contacts the cam surface 34d, the key mountain height corresponding to the key code can be set with high accuracy. Further, when the key crest is formed by the press working portion described later, the cam surface 34d (the key crest height setting portion 30) directly receives the reaction force at the time of the press working, so that the contact surface 27 and the cam surface 34d are in contact with each other. Contact is maintained. That is, the key pile height setting unit 30 is configured to directly receive a reaction force due to press working. As a result, the key pile machining dimensional accuracy can be stabilized and improved without changing the positional relationship between the key that is the workpiece and the key pile height setting portion during the key pile machining.

(Press working part 40)
The press working unit 40 is configured by mounting and fixing a press working base 42 on a base board 50 and mounting a press lever 44, a punch 45, a die 46, a spring 47 and the like on the press working base 42.

  As shown in FIGS. 2, 4A, and 4B, the press working base 42 is provided with a lever fulcrum 42a, and the press lever 44 can be rotated around the lever fulcrum 42a. The rod-shaped punch 45 is supported by the press working base 42 so as to be movable up and down. The punch 45 is biased upward by a spring 47, and the upper end portion 45 a of the punch 45 is in contact with the action portion 44 a of the press lever 44. By the rotation operation of the press lever 44, the punch 45 is moved downward by the action portion 44a of the press lever 44.

  The lower end 45b of the punch 45 is formed with a key crest-shaped cutting tool for punching the key into a mountain shape. A die 46 corresponding to the shape of the lower end 45 b of the punch 45 is mounted on the press working base 42. By the combination of the punch 45 and the die 46, it is possible to perform press processing (punching) in which a key is punched into a mountain shape. The punch 45 and the die 46 can be exchanged for one corresponding to a key mountain shape.

  The member which comprises the key mountain processing apparatus 1 demonstrated above is mainly formed with metal materials, such as steel. The cam member 34 that requires wear resistance can be subjected to heat treatment such as quenching. In addition, punches and dies that are required to have strength and wear resistance by press working can be subjected to heat treatment such as quenching and tempering, for example, on tool steel.

(Key processing operation)
FIG. 5A is an overall perspective view showing a state in which a key that is a workpiece is set in the holding portion, and FIG. 5B shows a state in which the key that is the workpiece is set in the holding portion. It is a whole perspective view. FIG. 6A is a plan view showing a blank key before pressing a key that is a workpiece, and FIG. 6B is a plan view showing a key shape in the middle of key mountain formation during pressing. FIG. 6C is a plan view showing the key shape when the press working is completed.

(Blank key 101 set)
First, the blank key 101 shown in FIG. 6A is set on the Y moving stage 25 of the key mountain position setting unit 20. As shown in FIG. 5A, the mountain position setting lever 22 is moved largely, and the key mountain position setting unit 20 is moved forward. Holding the handle portion 101 a of the blank key 101, the blade portion 101 b is inserted into the holder 60 and set, and accommodated in the set groove 25 a of the Y moving stage 25. The clamp lever 14a is rotated to fix the blank key 101 and the holder 60 with the holding plate 12.

(Setting the mountain position)
As shown in FIGS. 3 and 5B, the X movement stage 21 is set to a predetermined X position by the peak position setting lever 22. The pitch plate 24 is previously mounted on the base board 50 with a pitch plate corresponding to the key code of the key to be processed. The X movement stage 21 is moved in the X direction by rotating the mountain position setting lever 22. Based on the key code of the key to be processed, the lever position is moved in accordance with the code hole 24a of the pitch plate 24.

(Setting the mountain height)
As shown in FIGS. 2, 3, 4 (a) and 5 (b), the Y movement stage 25 is set to a predetermined Y position by the cam member 34. A cam member 34 corresponding to the key code of the key to be manufactured (replicated) is mounted in advance on the slit portion 32 a of the height setting base 32. The lever 34a of the cam member 34 is rotated and set to a mountain height corresponding to the set mountain position. Since the abutting surface 27 of the Y moving stage 25 is urged by the urging spring 26 in the direction of the key crest height setting unit 30, it abuts on the cam surface 34 d of the cam member 34.

(Press working)
As shown in FIG. 5B, the punch 45 is moved downward by the action portion 44 a of the press lever 44 by the rotation operation of the press lever 44. The lower end portion 45b of the punch 45 acts on the blank key 101, and the press lever 44 is further pushed down, whereby a part of the blade portion 101b is punched out. By this pressing (punching), a key crest 102c having a predetermined shape is formed on a part of the blade portion 102b as shown in FIG. 6B.

  During the press working, when the lower end 45b of the punch 45 acts on the blade portion 101b, the blank key 101 (blade portion 101b) has a downward punching force f1 as shown in FIG. A reaction force f2 due to machining in the direction of the key peak height setting unit 30 acts. Since the reaction force f2 at the time of pressing is directly received by the cam surface 34d (key peak height setting portion 30), the contact surface 27 and the cam surface 34d are in strong contact. That is, since the holding unit 10 (key mountain position setting unit 20) in which a key as a workpiece is set is configured between the press processing unit 40 and the key mountain height setting unit 30, The key pile height setting unit 30 directly receives a reaction force due to press working. As a result, the key pile machining dimensional accuracy can be stabilized and improved without changing the positional relationship between the key that is the workpiece and the key pile height setting portion during the key pile machining.

  The crest position setting lever 22 is sequentially moved in accordance with the code hole 24a of the pitch plate 24, and the lever 34a of the cam member 34 is rotated correspondingly to correspond to this, so as to correspond to the set crest position. Set to mountain height. In this manner, the blade portions 101b and 102b are pressed while setting the mountain position and mountain height according to the key code. If necessary, turn the key upside down and apply key piles on both sides of the blade. Thereby, as shown in FIG. 6C, a predetermined key mountain shape 103c is formed on the blade portion 103b, and a duplicated key 103 is formed.

(Removing the key 103)
As shown in FIG. 5A, the mountain position setting lever 22 is moved largely, and the key mountain position setting unit 20 is moved forward. When the clamp lever 14a is rotated to loosen the screw portion 14b, the holding plate 12 is urged upward by the urging force of the coil spring 16, thereby releasing the clamp. The completed key 103 is taken out, and the key pile processing is completed.
