Description

[Detailed explanation of the idea] This invention relates to a crimping machine.

A conventional caulking machine is described in Japanese Patent Application Laid-Open No. 12473/1982, and as shown in FIG. 4, a rotor 31 is rotatably installed in a housing 30, and a rotation axis Two punches 32 that exert an inclination of θ and θ are provided so that their caulked portions (tip concave portions) protrude from the opposing end surfaces of the rotor, and the pin 33 of product A located outside both punches 32 is inserted into the pressing shaft 34. Pressurize with punch 32
There is one in which the inside of the pin 33 is caulked by the action of a recess formed at the tip at the same time as the pivoting movement.

However, in this crimping machine, since the position of the tip of the punch 32 is fixed, the crimping part is always in a fixed position.

Therefore, for example, as in the case of a drawer, the inner circular surface of the side plate is the caulking position, and the distance between the outer surfaces is constant, and since the thickness of the side plate is different, the distance between the inner surfaces is different.

That is, when crimping several types of products with different distances between the two crimping positions, it is not necessary to replace the punch 32 with a length corresponding to the crimping position of the various products, or to change the mounting position of the punch 32. Must not be.

Replacing or changing the position of the punch 32 is complicated and troublesome for the operator.

The purpose of this invention is to provide a crimping machine that can respond to changes in the crimped portion, taking the above points into consideration.

In order to achieve this purpose, in the crimping machine of this invention, the crimping shaft is moved and pressure-contacted from the inside of two separated members to be crimped, and a pair of sliders are attached to the rails provided on the base of the crimping machine. The pair of sliders is attached so as to be slidable in the direction of the rail, and the pair of sliders are moved toward and away from each other by appropriate means.A caulking shaft that rotates and swings is provided on the end face of both sliders in the direction in which they move apart. A catch seat facing the caulking shaft is provided, and when both sliders slide in a direction away from each other, the caulking shaft comes into pressure contact with the catch seat with the member to be caulked interposed therebetween.

With this structure, the member to be crimped is interposed between the crimping shaft and the pedestal with the sliders close together, and while the crimping shaft is rotated and swung, both sliders are separated, and the member to be crimped is interposed. Press it against the pedestal and caulk.

At this time, even if the crimping position changes depending on the product, this is handled by changing the amount of movement of the crimping shaft, that is, the amount of separation of the slider.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

As shown in the figure, a pair of sliders 3 and 4 are slidably attached to a rail 2 provided on a base 1 of the crimping machine.
Recess 3' in each slider 3,4.

A spherical tip of an arm 10 swingably attached to the base 1 via a pin 11 is fitted into each of the arms 4'.

The bases of both arms 10 are connected to a cylinder 15 via a link 12, a pin 13, and an L-shaped rotating piece 14, and when this cylinder 15 is driven, both sliders 3 and 4 approach each other via the arms 10 and the like. Or defect.

Both sliders 3, 4 are provided with a rotating shaft 5.5 in the sliding direction, and a belt 8 is attached to a pulley 7.7 of the rotating shaft 5, 5.
is wrapped around the belt 8, and the rotating shaft 5 is rotated via the belt 8 by a motor (not shown).

One end of the rotating shaft 5 protrudes from the end faces of the sliders 3 and 4 in the direction in which they are separated, and an eccentric crimping shaft 6 is protruded from the one end so that the crimping shaft 6 pivots and swings as the rotating shaft 5 rotates. It has become.

Further, a catch 9 for a member to be crimped is located on the base 1 and is opposed to the crimping shaft 6, and this catch 9 is movable only in the direction of the rail 2 on a support 16 provided on the base 1. The slider 3.4 is mounted, and its lower part is in pressure contact with an inverted triangular pressing body 20 via a roller 19, and a spring 21 causes the slider 3.4 to
It is biased in the direction of sinking inward (left and right direction), and when the pressing body 20 moves up and down by the cylinder 22, the slope 20
The roller 19 rolls on a, and the pedestal 9 moves from side to side.

Further, the base 1 is equipped with a hopper 17, and the member to be caulked is supplied from the hopper 17 to the catch seat 9 through a chute 18.

The embodiment is configured as described above, and its operation will be explained next.

First, as shown in FIG. 1, the pressing body 20 moves and the pedestal 9 is at the receiving position corresponding to the discharge port of the chute 18, and a member to be mounted, such as a roller C, is set on the pedestal 9. , and in a state where the rotary shaft 5 is rotating and the caulking shaft 6 is pivoting, the cylinder 15 rotates the rotary piece 14 and swings the arm 10 in the direction in which the end of the rotary piece 14 separates. The sliders 3 and 4 are brought close to each other.

In this state, as shown in Fig. 2, set the product, for example, the side plates a and b of drawer A, at a predetermined position between the caulking shaft 6 and the catch seat 9, and press them as shown in Fig. 3. After moving the body 20 downward to move the pedestal 9 within the movement range of the caulking shaft, the rotating piece 14 is rotated in the opposite direction to swing the arm 10 and the sliders 3 and 4 are moved. Slide it in the direction away from you.

That is, the sliders 3 and 4 are slid toward the seat 9 and pressed against the seat 9 with the member to be caulked interposed therebetween.

Based on the pressing of the sliders 3 and 4, the crimping shaft 6 is pressed against the member to be crimped while rotating and swinging, whereby the member to be crimped is crimped and attached to the product.

For example, rollers C are attached to side plates a and b of drawer A.

When the crimping work on the member to be crimped is completed, the sliders 3 and 4 are slid in the direction of approaching each other, and then the cradle 9
is removed and the product is taken out from the crimping machine, and the work of attaching the member to be crimped is completed.

During this work, even if the side plates a and b have different thicknesses, such as drawer A, for example, even if the crimping position changes, the amount of movement of the crimping shaft 6 (the amount of separation of the sliders 3 and 4) will change. That is, the sliders 3 and 4 move until the crimping shaft 6 comes into pressure contact with the member to be crimped, and the crimping operation can be performed without any problem.

As described above, according to the crimping machine of this invention, the crimping shaft is rotated and swung from the inside between two members to be crimped, and the crimping is carried out by pressing against the member to be crimped.
There is an effect that the two products set on both catches can be crimped at any position within the movable range of both crimping shafts.

In other words, for example, there are several types of products in which the outer surface distance between the side panels is constant, such as a drawer, but the distance between the inner surfaces varies depending on strength, position, etc. when mounting to a desk, etc., and both sides of the inner surface are crimped positions. This is advantageous when performing caulking work.
