JPS58135734A - Caulking method of platelike member - Google Patents

Abstract

PURPOSE:To elevate durability of a punch, and to obtain a product having good qualities, by forming a shape of a caulking part in the shape of a concave face, and caulking its part by a punch whose tip has a round or aquare plane. CONSTITUTION:In a state that to the upper end face of a notched recess 4b of a side plate 4, the lower face of a paper guide 2 is made to tightly adhere, and a projecting piece 4a is projected from the upper face of the paper guide 2, a caulking punch 5 is depressed. Both sides 4c of the concave projecting piece 4a are crushed and spread out to the right and left, and the side plate 4 and the paper guide 2 are coupled exactly. In this way, the caulking is executed by crusing both the sides 4c by the flat tip of the punch 5, therefore, even if the center of the punch 5 is shifted a little from the center of the projecting piece 4a, sufficient force is put on both the sides 4c and the caulking is executed exactly.

先端が破損しゃ丁いという欠点があった。By the way, since it is used as a bearing for the rotating shaft of the printer, the surface of the side plate (1) is subjected to surface hardening treatment such as nitriding treatment, and its hardness is extremely high. There was a drawback that the tip of the punch (3), which was very thin after being used, could be damaged.

る。The present invention has been made in view of the above points, and details of the invention will be explained below with reference to embodiments shown in FIGS. 4 to 6. This embodiment shows a constriction structure between a side plate (4) and a paper guide (2) of a small printer, similar to the conventional example described above, and parts that are the same as the conventional example are given the same numbers and details thereof will be omitted. In the figure, C1 (51 is a patterned punch whose tip has a round or angular flat surface. Also, the side plate (4)
A notch recess (4b) is provided on the upper side of the drawing, and a concave The (4a) is provided at the bottom of the notch recess 1p (4b).
As shown in Figure 5, the protruding piece (4a) of the side plate (4) is placed so that the lower surface of the paper guide (2) is aligned with the upper end surface of the notch (4b) of the side plate (4). Bring it into close contact. Then, when the crest punch t51 is pushed down with the concave protrusion (4a) protruding from the upper surface of the paper guide (2), the sixth
Both sides (4C) of concave protrusion 8 (4a) as shown in the figure.
is crushed and pushed to the left and right. As a result, the side plate (4
) and the paper guide (2) are securely connected. However, since both sides (4c) of the protruding piece (4a) are thinned in advance, it can be done without requiring the same force as in the past. or,
The tip of the punch (5) has a round or angular flat surface, so it is easy to process and has good durability. Therefore, punch (
The material 5) does not need to be a particularly expensive material either. Also, the forgiveness is not done by biting into both shoulders (IC) as in the past, but by crushing both sides (4C) with the flat tip of the punch (5), so the center of the punch (5) Even if the center of the thrust X (4a) is slightly deviated from the center, sufficient force is applied to both sides (4c) and a reliable strangulation is performed.
