JP2001286962A - Falling off stop forming apparatus of wire shaped holding part fixed to work - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a working apparatus not falling off a linear wire shape holding part fixed to a work from a hand. SOLUTION: A work is held at both side of a positioning apparatus to push up the work having a wire shaped holding part. A chuck apparatus to position left/right and a bending chuck apparatus to bend a wire tip are arranged, a work discharge pin is protruded to a recessed part of the bending chuck by spring elastic force.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing device for bending a wire end fixed to a work with a bending chuck.

[0002]

2. Description of the Related Art Conventionally, an apparatus for bending a wire end fixed to a work with a bending chuck is known.

[0003]

When being bent, it sticks to the bending chuck, and must be released by one hand, resulting in poor productivity. In addition, even if the bending is automated, the machine will have to be stopped and separated because it sticks even if it is automated.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to clamp a work on both sides of a positioning device that pushes up a work having a wire-like gripper,
A chuck device for positioning left and right and a bending chuck device for bending the tip of a wire are provided, and a work discharge pin protrudes into a concave portion of the bending chuck by elasticity of a spring.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the illustrated embodiments. Reference numeral 1 denotes a base on which an air cylinder 2 is fixed, and the air cylinder 2 has a vertically movable plate 4 on which a jig 3 is mounted, which is vertically movable by a well-known air cylinder. Reference numeral 5 denotes a work to which a linear wire-shaped gripping portion 7 is fixed, which is inserted into the jig 3. Reference numeral 9 denotes a well-known air chuck for holding the wire-like holding portion 7 in the jig 3 and holding an intermediate portion of the wire-like holding portion 7.
Reference numeral 10 denotes a bending chuck which slides in the horizontal direction by a well-known air cylinder which bends a tip portion of the work 5, and a projection 1 which bends an upper end of a linear wire-shaped gripping portion 7 on one side.
1 and a recess 13 for receiving the bent recess 12 is formed on the other side. Reference numeral 14 denotes a work discharge pin that is pushed by the spring 15 into the recess 13 of the bending chuck 10 and protrudes. Reference numeral 16 denotes a plate to which the work discharge pin 14 is fixed, 17 denotes a regulating member, and 18 denotes a guide pin.

Next, the operation will be described. The work 5 is fitted into the jig 3 which is expanded so that the work 5 can be easily fitted. Next, an intermediate portion of the wire-shaped grip portion 7 of the work 5 in the jig 3 is held by a chuck 9 which slides in a horizontal direction by a well-known air cylinder. Next, the bending chuck 10 bends the linear wire-shaped gripping portion 7 into a curved shape with the projection 11 and the concave portion 13 which bend the distal end of the wire-shaped gripping portion 7. At this time, the work discharge pin 14 protruding into the recess 13 is flush with the recess 13 against the elasticity of the spring 15, and when the bending chuck 10 is opened, the work discharge pin 14 is moved into the recess 13 by the spring 1.
The work is easily discharged because the wire protrudes by 5 and detaches the wire attached to the concave portion 13. Note that the workpiece discharged according to the present invention is formed with a gripping portion 19 made of a resin as shown in FIG. 8 at a portion bent in the next step. Abbreviate.

[0007]

According to the present invention, a chuck device for holding a work on both sides of a positioning device for pushing up a work having a wire-like gripping portion and performing right and left positioning and a bending chuck device for bending a wire tip are provided. The work discharge pin protrudes into the recess of the chuck by the elasticity of the spring, and the end of the wire-shaped grip is bent to form the resin grip in the next step. Prevent,
Work can be performed smoothly.
