能である。Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a stamping apparatus for stamping a production number or the like on a work surface. 2. Description of the Related Art In a conventional stamping apparatus, each support member of a stamping head and a receiving portion is independent, and a receiving block abuts on the back side of the stamping portion of a work, and a hydraulic cylinder or the like starts from the front side. The stamp was hit. [0003] In the above-mentioned conventional example, the embossed portion and the receiving block are independently and separately fixed. In particular, since the receiving block is fixed on the base of the apparatus, the back surface of the stamped portion of the work must be brought into close contact with the receiving block. At this time, a gap is formed between the receiving portion and the back surface of the stamped portion. This is likely to occur, and if the stamping is performed with this gap, cracks may occur in the stamped portion. In addition, such a gap is inevitably generated due to dimensional variations of the work. Therefore, an object of the present invention is to minimize the occurrence of such a gap. [0004] Means for Solving the Problems] engagement Ru inventions to engraving device of the present application for solving the above-embossing surface side while supported by receiving portions of the embossing portion rear surface of the workpiece in embossing apparatus configured to strike the head, the embossing head moves back and forth freely to support the one end portion of the slider that is movably supported relative to the base which forms the base of the device, and at the other end By integrally providing a receiving portion in the vicinity of the projecting position of the embossing head at the time of hitting, a slider, an embossing head and a receiving portion are integrated to form an embossing unit, and the embossing unit is adjusted in the striking direction. Move it in parallel so that the receiving part is in contact with the
Was. [0005] Further, between the slider and the base,
Air cylinder for moving the slider in the striking direction
And an elastic member for urging and moving in the direction opposite to the striking direction.
Of the elastic member against the elasticity of the elastic member.
Move the slider in the direction of impact to
Position the receiving part on the back of the embossed part with a gap,
Then, by returning the air cylinder, the elastic member
With the restoring force of the above, the receiving part is in close contact with the back of
It is characterized in that it is made to be. According to the first aspect of the present invention, the receiving portion is formed as an embossing unit integral with the embossing head, and is slidable with respect to the base. After insertion, slide the embossing unit so that the receiving portion is in close contact with the back side of the embossed portion of the work. This makes it easy to adjust the alignment of the receiving portion with the embossed portion and increases the degree of adhesion even if the size of the work varies, so that the possibility of cracking during embossing is reduced. In addition, the slider is moved by the air cylinder.
Move in the hitting direction and set the receiving
After positioning with a gap, return the air cylinder
The elastic member moves the embossing unit in the direction opposite to the striking direction.
The receiving part comes into contact with the back of the stamped part of the work
At the same time, the degree of adhesion can be kept higher by the elasticity of the elastic member. Moreover, an excessive impact force at the time of stamping can be reduced by the elastic member. An embodiment will be described below with reference to the drawings. FIG. 1 is a perspective view of the whole embossing device, FIG. 2 is a diagram showing a state before adjustment of the receiving portion, and FIG. In this embossing apparatus, an embossing unit 2 is slidably supported on a base 1 serving as a base in two orthogonal directions X and Y (FIG. 1). If the horizontal direction is Y, the embossing unit 2 is an air cylinder 3
Moves in the Y direction. The embossing unit 2 includes a substantially U-shaped slider 4.
The embossing head 6 is supported by the bent portion 5 on one end side so as to be able to move forward and backward, and is projected by the hydraulic cylinder 7 in the striking direction X for embossing. On the other hand, another bent portion is provided on the other side of the slider at a position facing the bent portion 5 to form a receiving portion 8. The receiving portion 8 is located in the vicinity of the tip of the embossing head 6 that protrudes at the time of embossing in the extension of the striking direction X, and has a rib 9 formed on the surface thereof integrally protruding toward the embossing head 6. I have. The slider 4 is moved in the hitting direction X by an air cylinder 11 attached to a support portion 10 of the base 1, and is urged to move in the opposite direction by a coil spring 13. This coil spring 13 is
And a protrusion 12 integrally extending from the slider 4 extending therethrough. As shown in FIG. 1, the work 15 of this embodiment is
Is a crankcase of a motorcycle, and a part of a flange portion 16 forms an embossed portion of the present invention, in which a manufacturing number or the like is engraved by the embossing head 6. As shown in FIGS. 2 and 3, the relationship between the flange 16 and the receiving portion 8 is such that the slider 4 is moved in the striking direction X by the air cylinder 11 and further moved by the air cylinder 3.
Ri When embossing unit 2 Ru is moved in the Y direction, of the receiving portion 8
When the air cylinder 11 is retracted , the rib 9 is moved in the opposite direction by the coil spring 13 so that the rib 9 and the back surface of the embossed portion are in close contact with each other. become. The work 15 is fixed on a jig 17 independent of the base 1 in advance. However, the base 1 and the jig 17 may be integrated. Next, the operation of this embodiment will be described. First,
When the embossing unit 2 is moved in the striking direction X against the coil spring 13 by the air cylinder 11 and the embossing unit 2 is further moved in the Y direction by the air cylinder 3, the receiving portion 8 The work 15 is inserted into the back side of the flange portion 16 as a stamped portion with a slight interval t (FIGS. 1 and 2). Subsequently, when the air cylinder 11 is retracted, the slider 4 moves in the direction opposite to the striking direction X by the restoring force of the coil spring 13, and the receiving portion 8 comes into close contact with the back side of the flange portion 16 (FIG. 3). . Then, when the embossing head 6 is advanced by the hydraulic cylinder 7 and the front side of the flange portion 16 is embossed, the flange portion 16 is tightly supported by the receiving portion 8 on the back side, so that the predetermined embossing without cracking occurs. Is done. As described above, the embossing unit 2 in which the receiving portion 8 is integrated with the embossing head 6 is provided so as to be independent of the work 15 and to urge the receiving portion 8 to be in close contact with the flange portion 16 by the coil spring 13. As a result, even if the flange portion 16 of the work 15 has dimensional variations, the receiving portion 8 can be securely brought into close contact with the flange portion 16, facilitating the work of close contact and preventing the occurrence of cracks. It should be noted that the present invention is not limited to the above embodiment, and various applications are possible. For example, the coil spring 13 may be another type of elastic member such as a disc spring or a rubber block. In addition, it is possible to engrave various metal product surfaces.
