Description

[Detailed description of the invention] (1) Technical field of the invention The present invention relates to a jig that can simultaneously bend a large number of elongated metal objects.

(2) Prior Art and Problems Conventionally, the bending of a metal sheet metal product having a shape as shown in FIG. 1 a or b is performed in multiple steps using a general-purpose press. ○Process using NC bender or electric positioning device. ○Process using a special mold.
Processing methods such as

Both of these processing methods process one workpiece at a time.
Since this method involves individual bending, it has the disadvantage that it requires a large number of bending steps for small parts.

(3) Purpose of the invention In view of the above-mentioned drawbacks of the conventional art, the present invention provides a jig for simultaneous bending of multiple long and slender metal objects, which can bend a large number of pieces at the same time so that the number of bending steps per piece is reduced. The purpose is to

(4) Structure of the invention According to the invention, the purpose is to provide a jig for simultaneously bending a large number of slender metal objects, which includes a clamping jig for fixing a plurality of elongated workpieces, and an end face of the workpieces. and a positioning jig for aligning and fixing with the clamp jig, the clamp jig comprising:
Two presser plates that have a length that allows multiple workpieces to be lined up and fixed, and that are connected at one end with a hinge pin and can be opened and closed; and a clamp fitting provided at the other end of the presser plate. and a magnetic seal adhered to the inside of two presser plates, and the positioning jig is made of a rectangular sheet metal, and the edge of the workpiece is brought into alignment by abutting against the edge of the positioning jig. To provide a jig for simultaneously bending a large number of elongated metal objects, characterized in that a stop is formed and a plurality of grooves into which the clamp jig can be inserted are formed in a flat plate part in parallel with the stop. achieved by.

(5) Example of implementation of the idea Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a diagram for explaining a jig for simultaneously bending a large number of elongated metal objects according to the present invention. In the figure, 1 indicates a clamp jig, and 2 indicates a positioning jig.

This embodiment consists of a clamping jig 1 and a positioning jig 2. The clamping jig 1 has two presser plates 3 and 4 connected by a hinge pin 5 at one end so that the clamping jig 1 can be opened and closed freely. A removable clamp fitting 6 is provided at the end, and elastic magnetic seals 7, 7' are provided inside the holding plates 3 and 4, respectively.
It is constructed by pasting. Also, positioning jig 2
, one end of a rectangular sheet metal is bent to form an abutting part 8 that abuts the workpiece, and a groove 9 into which the clamp jig 1 can be fitted is provided in the flat plate part parallel to the abutting part 8. Multiple pieces are formed. The depth of the groove 9 is set so that when the clamp jig 1 is fitted, the upper surface of the magnetic seal 7' of the lower holding plate 4 is flush with the flat surface of the positioning jig 2.

The usage of this embodiment configured in this way will be described in the third section.
This will be explained using figures.

First, open the holding plates 3 and 4 of the clamp jig 1,
The lower pressing plate 4 is fitted into the groove 9 of the positioning jig 2. At this time, the groove 9 is selected at a position convenient for bending the workpiece. Next, a plurality of elongated workpieces 10 cut into predetermined dimensions from sheet metal are arranged on the positioning jig 2, and their ends are brought into contact with the abutment 8 to align them. Next, the presser plate 3 above the clamp jig 1 is closed and clamped by the clamp fitting 6. As a result, multiple workpieces 1
0 is fixed to the clamp jig 1 with the ends aligned.
In this state, if the clamp jig 1 is removed from the positioning jig 2 and the workpieces 10 are bent using a press machine, a plurality of workpieces can be processed simultaneously.

The magnetic sheets 7 and 7' bonded to the presser plates 3 and 4 of the clamp jig 1 are particularly effective when the workpiece 10 is a magnetic material, and their magnetic force attracts the workpiece 10. It is easy to align the ends, and when the upper and lower presser plates 3, 4 are clamped, the elasticity of the magnetic sheets 7, 7' makes it possible to equalize the fixing force applied to each workpiece 10.

(6) Effects of the invention As explained in detail above, the jig for simultaneous bending of multiple pieces of long and slender metal pieces according to the present invention has a simple configuration of a clamping jig and a positioning jig, and can perform simultaneous bending of many pieces of long and slender metal pieces. This has a great effect in that it contributes to reducing the number of bending steps.
