摘要： PROBLEM TO BE SOLVED: To provide a dot impact system print head capable of prolonging the life time by enhancing durability of a pin.
SOLUTION: A leaf spring 1 is provided, at the forward end part 11 thereof, with a holding hole 12 penetrating in the thickness direction and a pin 2 is provided, at the intermediate part in the axial direction thereof, with an outward flange 21 having a seat surface 21a and, on the proximal end side of the outward flange 21 in the axial direction, with a shaft part 20 being inserted into the holding hole 12. The pin 2 is secured to the leaf spring 1 by caulking the shaft part 20 from the other surface 1B side of the leaf spring 1 under a state where the seat surface 21a of the outward flange 21 is pressed against one surface 1A of the leaf spring 1. The seat surface 21a of the outward flange 21 in such a pin 2 is formed such that the radial outside is displaced more to the proximal end side (shaft part 20) in the axial direction of the pin 1 in a natural condition.

摘要： PROBLEM TO BE SOLVED: To develop an inexpensive abrasion proof pin head material contributive to prolong the lifetime of the print pin in an impact printer head. SOLUTION: A material similar to a base material of iron alloy is employed as a pin head material. The forward end part is coated with tin plating of low material cost by a plating method suitable for mass processing. It is then heat treated to form an Fe 3 SnC compound for which Vickers hardness of 500 or above can be expected. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE: To provide a steel printing wire for a dot printer made excellent in rustproof properties without lowering abrasion resistance and breakage resistance. CONSTITUTION: A steel printing wire for a dot printer is characterized by that the surface roughness of the outer peripheral surface of a shaft part is 0.30μmRmax or less and the number of pit like block spots with a diameter of 1.5mm or more is 5/100cm or less on the scanning electron microscope photograph (accelerated voltage 15kV, magnification 1000) of the outer peripheral surface of the shaft part. A method for producing the steel printing wire for the printer is characterized by applying dry barrel treatment by a vibration or rotary barrel machine.

摘要： PURPOSE: To suppress the trouble such as an increase in the number of processing processes as a whole or the occurrence of bending by cutting a strand into specific length and processing the leading end of a wire so as to remove the edge thereof before applying barrel-polishing thereto. CONSTITUTION: Since the edge 3a formed by the outer peripheral surface 1a of a wire (a) and the leading end surface thereof is sharp, the insertion of the wire (a) in the guide hole of a wire guide is difficult. As one example, a drawing B shows a state such that the edge of the wire (a) is ground into a truncated cone shape by chamfering processing. A drawing C shows such a state that the ground edge (b) is subjected to barrel-polishing and the skin of the outer peripheral surface and the fatigue strength under the outer peripheral surface are improved and edges 4c, 5c are enhanced in the insertion properties into the guide hole. A leading end surface and a conical surface 6c are slightly improved in surface roughness and, from the aspect of the insertion properties of the guide, the grinding meshes of the conical surface are desirably parallel or oblique with respect to a bus as shown by (c). A drawing D shows the end surface 2d subjected to beads blasting treatment of C.

摘要： PURPOSE:To connect a metal button and a print wire head assuredly at a cost lower than in brazing by inserting a print wire having a head part larger than a wire diameter into a metal button having a print wire and an insertion hole, and caulking it in crimping. CONSTITUTION:A print wire 2 having a head part larger than a wire diameter is inserted into a metal button 1. At this time, the diameter of the print wire 2 is 0.31mm, the diameter of the head part is 0.38mm, and a hole diameter of a skirt 1a is 0.39mm. When the head part can be inserted, the hole diameter of the skirt 1a can be smaller than the diameter of the head part. By caulking a print pin in cold crimping, a wire head 2a is prevented from falling down.
