Next, the usage and operation of the manual stamping machine with the above configuration will be explained. After checking the thickness of the object to be stamped, turn the dials 105, 105,
Adjust the mm scale or numbers (not shown) attached to the dials 105, 105 to the thickness of the object to be engraved. Then, a rotation corresponding to the amount of rotation of the dials 105, 105 is transmitted to the eccentric cam 100 via the shaft 99, so that the fulcrum position of the rotating arm 102 is displaced by the amount of eccentric rotation of the eccentric cam 100, and the thickness of the marking object is adjusted. The corresponding fulcrum position is adjusted.

In this state, lift the manual stamping machine slightly, place the object to be stamped on the base plate 93, position it with the ruler 108 so that it is directly below the character ring 9, and then lift the manual stamping machine. The pull-up lever 81 can be lifted up slightly as described above, or lowered so that the letter ring 9 hits the designated position on the object to be engraved.
is pulled down against the elasticity of the spring 87 as shown in the second figure. Then, the arm 84 moves above the cylinder 27 using the shaft pin 82 as a fulcrum, and at the same time, the roller 85 rolls and pushes up the lower end of the hammer 29, so the hammer 29 moves against the coil spring 54.
It is pushed up while being guided by the guide rail 39 while resisting the elasticity of. In the process of pushing up the hammer 29, the guide plate guide 32 passes through the through hole 50 of the distributor housing 44, and then the pointed end of the guide plate guide 32 passes through the through hole 60 of the disc 56 of the stopper release shoe 55. Next, the guide plate 63 is moved up while cutting into the through hole 66 of the guide plate 63, which is slightly shifted from the through hole 60, and the guide plate 63 is rotated in the direction of the arrow in FIG. is through hole 66
When passing through, the through hole 66 communicates with the through hole 60, and at the same time, each through hole 65, 65 of the guide plate 63 moves to a position where it communicates with each through hole 59, 59 of the disc 56, and each feed rod 25 , 25. While the point of the guide plate guide 32 passes through the through hole 66 of the guide plate 63, the upper end of the guide groove 33 of the hammer 29 rises while receiving the upper end of the stopper 40, so that the upper end of the stopper 40 touches the leaf spring 43. Due to elasticity, it slides while being pressed against the groove bottom of the guide groove 33, and the moment the engagement step 35 passes, it moves to the position where it engages with the engagement step 35 as shown in the fourth figure, and the hammer 29 is placed in the raised position. to be locked. Note that when the hammer 29 is locked in the raised position and the pull-down of the pull-up lever 81 is released, the pull-up lever 81 receives the elasticity of the spring 87 and returns to its original position.

After locking the hammer 29 in the raised position as described above, while pulling the cylinder 27 slightly toward you and pressing the letter ring 9 against the object to be engraved,
The push button 71 is pushed down against the elasticity of the coil spring 76. Then, the upper ends of the respective feed rods 25, 25 pass through the respective through holes 65, 65 and pass through the guide plate 63 as shown in FIG. The introduction part 58 is introduced into the introduction groove 42 of the stopper 40, and moves the upper end of the stopper 40 against the elasticity of the leaf spring 43 to a position where it is removed from the engagement position with the engagement step part 35. Then, the lock of the hammer 29 is released, and the hammer 29 suddenly descends due to the action of the elasticity accumulated in the coil spring 54 when the hammer 29 is pushed up and hits the base plate 5, and the impact force is applied to the character ring. 9, and the stamp is applied to the object to be stamped. Therefore, I lifted the manual stamping machine slightly and placed the object to be stamped on the base plate 93.
Pick it up from above.

When the push button 71 is released at the same time or immediately after the hammer 29 is released, the guide plate center pin 69 is pushed up by the elasticity of the coil spring 76, so the stopper release switch 5
5. The guide plate 63 and the push button 71 are also pushed up to their original positions, and the upper ends of the feed rods 25, 25 are retracted from the respective through holes 65, 65 of the guide plate 63. Then, the guide plate 63 returns to its original position under the force of the spring 72, and the through holes 65, 65 are connected to the through holes 59, 5 of the stopper release shoe 55 as shown in FIG.
9 to prevent the feed rods 25, 25 from penetrating.

In this state, push button 71 is pressed by coil spring 76.
When you push down against the elasticity of each feed rod 2
Since the upper ends of 5 and 25 are pushed down while touching the lower surface of the guide plate 63, each feed rod 25 and 2
5 is pushed down against the elasticity of the coil spring 17. Then, the feed pawl 18 descends and rotates the ratchet wheel 8 by one pawl in the direction of the arrow in FIG. Only one character is sent.

When the push button 71 is released,
At the same time, the guide plate 63 and push button 71 are pushed up to their original positions by the elasticity of the coil spring 76.
Since each feed rod 25, 25 is pushed up to its original position by the elasticity of the coil spring 17, the feed pawl 18 is raised to its original position.

By repeatedly pressing down and releasing the push button 71, the character wheel 9 can be continuously fed. To advance characters in this manner, the manual embossing machine is raised horizontally or at an angle where the character wheel 9 can be easily seen, and the push button 71 is pressed down repeatedly while viewing the characters on the character wheel 9. Then, when all the necessary characters have appeared, it is sufficient to stop pressing the push button 71.

In the present invention, the manual stamping machine may be used by being attached to a dedicated mount as in the above embodiment, or may be used alone. That is, threaded bolts 114, 114
By loosening the machine frame 1 and removing the machine frame 1 from the support plate 104, the manual stamping machine can be separated from the rotary arm 102, or alternatively, the manual stamping machine can be manufactured without a dedicated mount and its cylinder 27 While gripping the name plate, attach the lower side of the side plates 2, 2 of the machine frame 1 to the name plate,
Press the character ring 9 against the object to be engraved, such as a mechanical part.
The stamp may be made by bringing the mark horizontally into contact with the marking surface and operating the push button 71 in the same manner as in the above embodiment. In this case, if the object to be engraved is horizontal,
It has the advantage that it can be stamped in any direction, vertically or diagonally, and that the manual stamping machine can be carried and stamped wherever the object to be stamped is located.

In each of the above-mentioned embodiments, whenever the material of the object to be engraved changes from steel to steel, aluminum, resin, etc., the coil spring 54 may be replaced with one having a spring pressure suitable for each material. . In addition, the machine frame 1 can be replaced as needed, including one that supports the series number font wheel, one that supports the date font wheel, and one that changes the size of the characters with these font wheels. May be used.

Since the present invention is configured as described above, the mechanism is simple, the manufacturing is easy, and the price can be reduced compared to conventional stamping machines that use hydraulic pressure or compressed air. In addition, the same push button allows you to perform two operations, one for feeding the letter ring and the other for engraving, with a single touch, making it easy to change letters.
The machine frame allows stamping by applying uniform force to the entire letter surface while keeping the letter surface horizontal to the target object, and by replacing the coil spring, the stamp can be made to match the strength of the target object. Since there is no need to adjust the force, it is possible to make clear markings on various marking objects without requiring any skill. In addition, when it is installed on a dedicated mount, the force required to support the engraving machine itself is eliminated, so even those with weak strength, such as women, can stamp reliably. It has various effects such as being able to easily carry it to a certain place and engrave it from any angle.
