Description

[Detailed Description of the Invention] The present invention relates to a cut press device that continuously cuts a shape material at regular intervals.

Conventional shape cutting press equipment uses separate drive sources for the drive means to move the die at the same speed in the direction of feed of the shape material, and the drive means to move the cutting blade up and down to cut the shape material. .

Therefore, the apparatus is complicated and large-scale, and there has been a demand for a smaller cut press apparatus and a simpler operation.

In view of these circumstances, the present invention has developed a rotary rotary system that not only operates the gusset and cutting blade in a related manner using a single drive source, but also allows the cutting blade to operate independently by installing a clutch mechanism. The present invention aims to provide a cut press device.

The rotary cut press device of the present invention includes a central rotating shaft 2 connected to a drive source 1, upper and lower crankshafts 4°15 having interlocking means with the central rotating shaft 2, and a vertically movable shaft at the tip of the upper crankshaft 4. Slider 7 attached freely and the slider 7
A cutting blade 11 is mounted to be slidable in the feed direction P of the profile material, and a cutting blade 11 is mounted at a corresponding position below the cutting blade 11, and is movable left and right in the sliding direction of the cutting blade 11 and interlocks with the cutting blade. a lower crankshaft 1 that controls the running of the guide set 13 at the same speed in the feed direction P of the shape material;
5, and a clutch mechanism that removably interlocks the central rotating shaft 2 and the lower crankshaft 15 or the upper crankshaft 4.

An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, a central rotating shaft 2 is connected to a drive source 1, and a central gear 3 is mounted thereon.

The upper crankshaft 4 is located above the central rotating shaft 2, parallel to the axial direction of the central rotating shaft 2, and is connected to the central gear 3.
An upper gear 5 that meshes with the upper gear 5 is attached.

The crank pin 6 at the tip of the upper crankshaft 4 has a slider 7.
The slider 7 is inserted into a horizontally elongated hole 7a bored in the center of the guide 8, and the slider 7 is mounted in the guide 8 so as to be able to move up and down.

That is, the elongated hole 7a is approximately equal to or slightly larger than the maximum rotating diameter of the crank pin 6, so that as the crank pin 6 rotates, the crank pin 6 moves through the hole 7 of the slider 7.
The slider 7 slides from side to side within a, and the slider 7 moves up and down by the maximum rotational diameter of the crank pin 6.

A guide rail 9 is provided below the slider 7 in a horizontal direction orthogonal to the axial direction of the upper crankshaft 4, and a slide table 10 is mounted on the guide rail 9 so as to be slidable left and right.

A cutting blade 11 is hung down on the lower surface of the slide table 10, and guide pins 12 and 12 are hung down and fixed at the waist.
2.12 is pivotally supported on a die set 13 installed at a corresponding position below the slide table 10 so as to be vertically movable.

25.25 is a clamp for engaging with the grip set 13 and clamping the shape material during cutting.

This clamp 25.degree. 25 is necessary when cutting a cylindrical shape material, but is not necessarily necessary when cutting a flat shape material.

The guide set 13 is movable in the feed direction P of the shape material, that is, in the direction of the left-right sliding force of the slide 10, by means of a lower crankshaft 15, which will be described later.

14.14 is the guide rail of Guiset 13, 22.2
Reference numeral 2 denotes guide pins that are erected and fixed on the left and right sides at a constant interval at the rear of the guide set 13.

Therefore, the guide set 13 and the slide table 10 operate integrally in the left-right direction.

The lower crankshaft 15 is located below the central rotating shaft 2, parallel to the axial direction of the central rotating shaft 2, and connects a lower gear 16 that meshes with the central gear 3 of the central rotating shaft 2 via a rolling bearing 17. I am wearing it.

That is, the lower gear 16 is rotatably attached to the lower crankshaft.

A clutch mechanism 26 is provided at the rear of the lower crankshaft 15, and a clutch plate 18 formed on the clutch body 25 is pressed against a clutch plate 19 provided on the lower gear 16, and the friction force causes the lower gear 16 to move from the central rotating shaft. The transmitted rotational force is transmitted to the lower crankshaft 15.

A roller 21 is rotatably supported on the crank arm 20 at the tip of the lower crankshaft 15, and this roller 21 rolls up and down the guide groove between the guide pins 22 and 22 of the guide set 13, thereby rotating the guide set 13. 1
Reference numeral 3 indicates a type that can freely travel in the feeding direction P of the mold material.

In this case, in order to keep the left and right running speed of the gusset 13 constant, the drive source 1 is controlled so that the rotational speed of the motor changes in a sinusoidal curve.

In other words, if the rotational speed of the motor is constant, the roller 21 supported by the crank arm 20 at the tip of the lower crankshaft 15 will undergo equidistant motion, and if this motion is considered only in the left-right direction, it will reciprocate left and right. The velocity is maximum at the center of the width and minimum at both left and right ends,
In other words, it becomes a simple harmonic motion.

Therefore, by sinusoidally changing the rotational speed of the motor of the drive source 1, the rotational speed of the motor becomes maximum when the guiset 13 is located at both ends of the left and right reciprocating width, and minimum when it is located at the center. If the adjustment is made, the guide set 13 will reciprocate at a constant speed within the left and right reciprocating width.

Note that, due to this, the vertical movement of the cutting blade 11 also becomes constant speed.

The operating state of the rotary cut press device having such a configuration is as follows: First, the clutch mechanism 26 is connected, and the shape material is continuously fed into the mold hole of the guide set 13 at a constant speed. When the amount reaches a predetermined value, power is transmitted from the drive source 1 to the upper and lower crankshafts 4, 15 via the central rotating shaft 2, and the slider 7 attached to the crank pin 6 at the tip of the upper crankshaft 4 is activated. It moves up and down in accordance with the rotation of the crank pin 6, and moves the slider 10 attached to the lower part of the slider 7 up and down at regular intervals.

That is, the cutting blade 11 is moved up and down.

At the same time, the roller 21 pivotally supported by the crank arm 20 at the tip of the lower crankshaft 4 rolls up and down in the guide groove between the guide pins 22 and 22 of the guide set 13.
The guide set 13 runs in the direction P of feeding the shape material.

When the sliding table 10 starts to descend from the uppermost position, the clamps 25 and 25 provided on both sides of the cutting blade 11 first engage with the tie set 13, and the die of the tie set 13 clamps the shape material.

In this state, the cutting blade 11 cuts the shape material while the sliding table 10 reaches the lowest position.

As mentioned above, depending on the shape of the shape, the clamp 25
．． 25 is not necessarily necessary.

At this time, the goose set 13 is running at the same speed as the shape material in the feed direction P of the shape material, and the slide table 10 pivotally supported by this goose set 13 also moves at the same speed in the feed direction P of the shape material, moving the shape material vertically from above. It is used for cutting.

The sliding table 10, that is, the cutting blade 11, which has reached the lowest position, is pulled upward according to the rotation of the crank pin 6, and the clamp 25, 25 and the grip set 13 are disengaged, thereby releasing the clamping of the shape material. The die set 13 is returned to the position before traveling again.

This operation is performed while each of the upper and lower crankshafts makes one revolution.

Next, in order to perform independent operation of the cutting blade 11, the clutch plates 18, 19 between the lower crankshaft 15 and the lower gear 16 may be released.

In this way, the rotational force transmitted from the central rotary shaft 2 to the lower gear 16 is not transferred to the lower crankshaft 15 by the rolling bearing 17, and therefore the cutting operation is performed while the left and right running movement of the gusset 13 is stopped. can only do the following.

By enabling the cutting blade 11 to operate independently in this way, it can be used not only for continuous cutting of a shape material but also for cutting and removing a deformed end of a shape material.

FIG. 3 shows another embodiment, in which, compared to FIG. 1, a clutch mechanism 34 is also provided on the upper crankshaft 4, and
The left and right traveling means of the Guiset 13 is controlled by a rack instead of being controlled by a crank arm.

That is, the clutch mechanism 34 provided on the upper crankshaft 4
has the same structure as the clutch mechanism 26 provided on the lower crankshaft 15, and the upper crankshaft 4 is equipped with an upper gear 5 which meshes with the central gear 3 of the central rotating shaft 2 via a rolling bearing 30.

A clutch body 33 having a clutch plate 32 is provided at the rear of the upper crankshaft 4. This clutch plate 32 is pressed against a clutch plate 31 provided on the upper gear 5, and the friction force causes the upper gear 5 to be moved from the central rotating shaft 2. The rotational force transmitted to the upper crankshaft 4 is transmitted to the upper crankshaft 4.

On the other hand, a spur gear 35 is attached to the tip of the lower crankshaft 15 at right angles to the axial direction of the lower crankshaft.

Further, a rack 36 is attached to the rear of the goose set 13 in parallel to the left-right running direction of the goose set 13, and this rack 36 and the spur gear 35 mesh with each other to control the running of the goose set.

The operating state of the rotary cut press device having such a configuration is as follows: First, both clutch mechanisms 34 and 26 are connected,
When the feed amount of the mold material reaches a predetermined value while the mold material is being continuously fed into the mold hole of the Guiset 13 at a constant speed, the drive source 1 passes through the central rotating shaft 2 to the upper and lower crank shafts 4, 15. The upper crankshaft 4 moves the cutting blade 11 downward from the uppermost position.

At the same time, the spur gear 35 of the lower crankshaft 15 rotates to move the rack 36 left and right at a constant speed.

That is, the guide set 13 is made to run in the direction P of feeding the shape material.

In this case, it is assumed that the rotational speed of the motor of the drive source 1 is constant.

In this way, cutting of the profile material is completed, and at the same time the cutting blade 11 returns to the initial position, that is, the uppermost position, the clutch mechanism 34 of the upper crankshaft 4 is released and the motor of the drive source 1 is rotated in the reverse direction. The spur gear 35 of the crankshaft 15 is rotated in the opposite direction to pull the gusset 13 back to its original position.

This operation is automatically repeated every time a predetermined amount of mold material is fed in to perform continuous cutting work.

In the above description, the motor of the drive source 1 is rotated in the reverse direction to pull back the goose set 13 that has traveled in the feed direction P of the shape material. When the engagement is completed, the spur gear 35 and the rack 36 are disengaged, and the gear set 1 is removed.
3 may be pulled back to the original position by an elastic member such as a spring.

In this way, there is no need to reversely rotate the motor of the drive source 1.

Since the rotary cut press device of the present invention is constructed as described above, it is possible to drive and control the cutting blade and the grip set at the same time using one drive source.

Therefore, it is not only possible to downsize, but also easy to operate, inexpensive to manufacture, and economical.

In addition, since a clutch mechanism is provided between the drive source and the tie set, the running of the tie set can be stopped as necessary.
Only cutting operations can be performed.

Therefore, even when adjusting the cut size of the shape material, it is only necessary to change the timing of engagement and disengagement of the clutch, and when changing the cut size of the shape material during work, there is no need to temporarily stop the work line and make adjustments.

With such a configuration, it is possible to immediately adapt to various cutting dimensions of the mold material.
