Description

[Detailed explanation of the invention] This invention is related to the improvement of a vise device that can be attached to a saw machine.
More specifically, the present invention relates to a vice device that prevents the vice surface of a stationary vice jaw from being caught in the material to be cut when the vice device on the material feeding side moves backward.

Generally, when feeding the material to be cut on a saw machine, etc., a main body vise device and a feed vise device are required.In particular, the feeding vise device that feeds the material to be cut is In order to do this, the forward and backward movements are repeated.

However, there is a problem in that when the feed vice device moves backward, the vice surface of the fixed vice jaw of the feed vice device and the uneven side surface of the material to be cut get caught, making it impossible to feed the material smoothly.

For this reason, conventionally, when the feed vise device moves backward,
In order to move the vice surface of the fixed vice jaw slightly backward from the fixed side reference surface of the material to be cut, place the fixed vice jaw slidably on the vice body, and then move the fixed vice back using a hydraulic cylinder, etc. A device has been proposed to do this.

However, in the above-mentioned cylinder direct-acting type devices, the fixed vice jaws slide against the vice body, so dirt, rust, etc. adhere to the sliding part, and as a result, the movement of the fixed vice jaws is affected. The disadvantage was that it worsened.

Furthermore, unless the sliding portion is made long to a certain extent, galling occurs in the vise body and the fixed vise jaws, resulting in an increase in the size of the entire device as well as the components of the cylinder.

Furthermore, as mentioned above, since it is a direct-acting type using a cylinder, it is necessary to increase the pressing force, and as a result, there is a problem that the cylinder itself has to be increased in size.

This invention was devised to effectively solve these conventional problems, and involves connecting a fluid pressure actuator to a fixed vice jaw via an eccentric mechanism, and attaching it to the fixed side reference surface of the material to be cut. On the other hand, a vise for a saw machine is designed to advance and retreat smoothly and with a small force, and to effectively prevent the vice surface of the fixed vise jaws from getting caught in the material to be cut, especially when the vise device moves backwards. It is provided to the device.

Hereinafter, a preferred embodiment of this invention will be described based on the accompanying drawings.

In the following explanation, the vertical direction in FIG. The lower force is referred to as "the unloading side X2 of the material to be cut M."

Furthermore, in Fig. 2, the left-right direction is the Y-axis direction (the moving direction of the vice device), and the left side is the "movable vice side Y1".
), the right side is called the "fixed (reference) vise side Y2J".

FIGS. 1 and 2 show a perspective view and a plan view of a horizontal bandsaw machine 1 for feeding and cutting a material M to be cut in fixed size increments, in which this invention is implemented.

This horizontal bandsaw machine 1 includes a cutting section 3 for cutting a material to be cut M, a support section 5 for placing and supporting the material to be cut M,
Furthermore, it is comprised of a vice mechanism part γ for clamping and fixing the material M to be cut and feeding the material in fixed size increments.

The cutting section 3 is a band saw blade 9. The saw blade consists of a maggot 11 and the like, and a pair of wheels (not shown) for rotatably suspending the band saw blade 9 are installed inside the saw blade 11.

The support portion 5 includes support rollers 13, 13 . ...and these support rollers 13, 13. It is composed of a frame 15, a table 1γ, etc. for erecting and supporting .

The material to be cut M is fed from the X-axis upward direction X1 to the X-axis downward direction X2, and is clamped and fixed by the vice mechanism section γ. . . . are arranged in an appropriate number along almost the entire length of the material feeding path of the material M to be cut.

That is, they are provided at appropriate intervals from the lower end of the button on the frame 15 in the X-axis direction to the position immediately in front of the main body vice device 19, which will be described later.

Support rollers 13, 13.・・・・・・is frame 1
It is rotatably supported by a roller frame 2L21 provided separately from 5.

This roller frame 21.21 is arranged at an upper position separated from the frame 15 by an appropriate distance, and a support member 23 for supporting the roller frame 21 is provided between the lower end surface of the roller frame 2L21 and the frame 15. It is an intervention.

This support member 23 is provided at a position where it does not interfere with the movement of the material feeding vice mechanism 25, which will be described later, during material feeding and during retreat.

That is, a space is formed between the lower end surfaces of the roller frames 21 and the frame 15 except for the part where the support member 23 is provided.

The vice mechanism section T is composed of a main body vice device 19 and a material feeding vice device 25.

The main body vice device 19 is a fixed vice jaw 2γ on the main body side.
and a movable vice jaw 29 on the main body side that can reciprocate toward and away from the fixed vice jaw 2γ, and is provided at a position immediately before the cutting position formed by the band saw blade 9.

Further, the material feeding vise device 25 includes a main body vise device 19.
Similarly, the material feeding vise device 25 is separated from the fixed vice jaw 31 (reference vice jaw 31) on the material feeding side and the movable vice jaw 33 on the material feeding side, and the material feeding vice device 25 can move toward and away from the main vice device 19 ( It has a structure that allows it to move forward and backward at will.

Furthermore, the movable vice jaws 29, 33 on the main body side and the material feeding side are operated by fluid pressure operating devices 35a, 35 such as hydraulic cylinders.
Fixed vice jaws 27 on the main body side and material feeding side via b
, and can freely move forward and backward in 31 directions.

Further, the material feeding vice device 25 is installed on a support frame 39 via a vice bed 31, and between this support frame 39 and the vice bed 3γ, the material feeding vice device 25 is moved in the X-axis direction. An actuating device 41, such as a hydraulic cylinder, is mounted for this purpose.

The tip of the actuating rod 43 in this actuating device 41 is connected to the second
As shown in the figure, it is fixed approximately at the center of the vice bed 3γ by appropriate means.

Therefore, when the operating rod 43 is extended, the vice bed 3γ is moved in the X-axis downward direction 3γ is moved in the X-axis upward direction X2, that is, in the direction away from the main vice device 19.

In other words, when the operating rod 43 is extended, the entire material feeding vise device 25 moves forward in the material feeding direction, and when the operating rod 43 is contracted, the entire material feeding vice device 25 moves backward.

A stopper 4 for regulating the forward position of the material feeding vise device 25 is attached to a mounting arm (not shown) in the vice bed 3γ.
5 is installed.

The gist of this invention is that the fixed vice jaw 31 (reference vice jaw 31) of the material feeding vice device 19 is configured to be able to move forward and backward with respect to the fixed side reference plane Z-Z of the material to be cut M during backward movement. This configuration will be described in detail below.

As shown in FIGS. 3 to 5, the fixed vice jaws 31 on the material feeding side are integrally mounted on both sides of the back of the fixed vice jaws 31 in a hollow vice body 41 that is erected and fixed on the vice bed 31. The flange portions 49.49 and the vice body 4γ are fitted together so as to sandwich the flange portions 49.49 provided in the vice body 4γ. The eccentric shaft 5 that constitutes
1.51.

Approximately at the center of the eccentric shaft 51.51 in the vice body 4T, a connecting plate 55.5 is provided with a semicircular arc-shaped retaining portion 53 that engages with the circumferential surface of the eccentric shaft 51.51.
5 are engaged and fixed via fixing bolts 57.57.

In addition, the support pin 61 is attached to the link par 59 that moves up and down in parallel to the vice surface 31a (reference surface 31a) of the fixed vice jaw 31.
It is rotatably supported via an angle of 61 degrees.

The linker 59 has an upper end thereof and a vice body 4.
It is always urged downward via an elastic member 63 such as a spring, which is interposed between it and the earth wall of γ, and a guide roller 65 is attached to the lower end of the elastic member 63.

A guide roller 65 attached to the lower end of the link par 59 is in contact with a piston rod 69 of a fluid pressure operating device 6γ, such as a hydraulic cylinder, which is vertically mounted on a vice bed 3γ or the like.

Therefore, when the fluid pressure operating device 6γ is extended, the linker 59 is pushed upward in FIG. The aging plates 55, 55, which are rotatably attached via 61, also move upward while rotating.

When the above-mentioned mounting plates 55, 55 move upward, the center of rotation O of the eccentric shaft 5L51, which is connected to the mounting plates 55, 55 through the fixing bolt 5γ, is oriented as shown in FIG. At position 1 of 01, it is pushed out to the right while rotating clockwise.

As a result, the vice surface 31a of the fixed vice jaw 31 moves on the fixed side reference surface 2-21 of the material to be cut M via the vice body 4γ supporting the eccentric shaft 51.51.

Contrary to the above, when the fluid pressure actuator 6γ is contracted, the linker 59 is pushed downward in FIG. 4 by the elastic force of the elastic member 63, thereby causing the coil
The holding plate 55.55 also moves while rotating downward.

As a result, the eccentric shaft 5L51 moves from its rotation center 01 to
While being pulled back at position 1, it moves to the left in FIG. It is pulled back to the position Zl-Zl, which is retreated by δ from the position Z.

That is, δ is the fixed side reference plane Z- of the fixed vice jaw 31
2, and this movement amount δ is:
It can be set depending on the stroke of the fluid pressure actuating device 6γ, the amount of eccentricity of the eccentric shaft 51, etc.

The above-mentioned operation is performed especially when the material feeding vise device 25 is retracted, and when moving to the carry-in side X1 of the material to be cut M in order to clamp the material to be cut. This prevents the vice surface 31a and the side surface of the material to be cut M from getting caught.

Then, the material to be cut M clamped by the material feeding vise device 25 is fed to the main body vice device 19 in fixed size portions by repeating the above-described operations.

Incidentally, in the above embodiment, the fixed vice jaw 31 of the material feeding vice device 25 was explained, but the main body vice device 19
Of course, it is also possible to implement the fixed vice jaw 2γ.

This invention connects a fluid pressure actuator to the fixed vice jaws via an eccentric mechanism as described above, and in particular, when the material feeding vice device 25 moves backward, the fixed vice jaws are connected to the material to be cut.
Because the vehicle was intercepted in such a way that it moved forward and backward relative to the fixed reference plane,
There is no possibility that the vice surface of the fixed vise and the uneven side surface of the material to be cut M will be caught or galled, and the material feeding work can be carried out smoothly and efficiently.

Also, since it is not a fixed vise gas slide type like the conventional one, dust and rust may adhere to the slide part.
There is no problem with the movement of the fixed vice jaws,
It can operate smoothly.

Furthermore, the overall structure of the device does not become large, and maintenance etc. are extremely easy.

Note that this invention is not limited to the above-mentioned embodiments, and may be implemented in other embodiments.
