JPS6233023A - Calking machine for pen tip fixture of sign pen - Google Patents

Abstract

PURPOSE:To perform the stabilized extension of a pen core for the prescribed length and the optimum and strong fitting by fitting the pen tip fixture for inserting the pen core to the inserting hole of the pen tip fixture and by performing the lengthening of the pen core projection with the advance of a female die and the fastening of the fixture pen tip part and the drum center part. CONSTITUTION:The pen tip fixture 14 that a pen core 13 is inserted into the pen tip fixture inserting hole 1 of a holding part A is fitted with its insertion. The pen core 13 is projected in the prescribed length by shaping its tip with a pen tip adjusting part 9 by advancing a female die B and the pen tip part 11 of the fixture 14 is fastened as well by a calking part 8 and the drum center part 12 of the fixture 14 is fastened by a punch core 3 by pushing a layer 4. The pen core 13 can be fixed in the optimum strength at two places on the pen tip fixture 14 stably on the work stage and the projection can be made in the prescribed length.

Description

DETAILED DESCRIPTION OF THE INVENTION A) Field of Industrial Application This invention relates to caulking of a pen tip fitting of a felt-tip pen.

Caulking is done by tightening a part of the nib metal fitting into which the pen core is inserted. There was often only one department. Therefore, the workers required considerable skill, and even then, the quality of the products varied. That is, if the caulking is too strong, the ink will not come out well, and if the caulking is too weak, the pen core tends to loosen, making it difficult to work properly.

Problems to be solved by the invention H This invention does not require any level of skill on the part of the workers, and it is of high quality, that is, the ink flows well, the pen core does not come loose, and the shape and length of the pen tip are fixed. The purpose is to easily process high-quality pen nibs with constant quality.

B) Means for Solving the Problems An embodiment of the present invention, which is implemented as a crimping machine for pen nibs, will be described below with reference to the drawings.

Figure 1 shows the state in which the pin/tip metal fitting is inserted into the gold holding part (support). Figure 2 shows a state in which the female mold is moved toward the holding part and the two collide. However, spear 3
As shown in Figures 1 and 1, the holding part (5) consists of a metal fitting hole (1), a punch hole (2), a punch core (3), and a lever (4) connected to the punch. (type) includes a pen nib introduction part (7), a crimping part (8), a pen nib adjustment part (9),
It is composed of a lever-driven protrusion αQ. Then, the holding part λ) and the female mold ■) are placed facing each other, and the female mold part) turns around and hits the holding part which is fixed to the base (5) with a stand (6). It is attached to the base so that it can move horizontally.

(e) For operation 21O, insert the metal fitting α◆ with the pen core (through) inserted into the pen light wave entry hole (1) of the holding part, move the female mold (B) horizontally, and When the female type IB is brought into contact with the holding part (4) as shown in Figure 2, the pen tip adjustment part (9) presses the pen core and adjusts its protruding length and the shape of the pen tip. Next, swage the metal pen tip αη with the female IBI S (
S) to crush and tighten, and at the same time lever drive protrusion ←0
presses the lever (4), moves the punch core (3), punches the center part (6) of the body of the metal fitting, and tightens it.

(f) Effects of the Invention As is clear from the above description, this invention has enabled the pen nib crimping process of felt-tip pens, which has traditionally been done manually and relied on skilled workers, to be performed by unskilled workers. Not only is it easy to do this, but it is also possible to perform strong and stable caulking without damaging the ink flow because the al caulking is done in two places: the pen tip (6) of the metal fitting and the center of the metal body (toward). , (b1) The length and shape of the protruding part α It is an invention.
