(Prior art) Conventionally, when processing materials (e.g. wire rods or bars) with hole dies or roller dies, it is necessary to apply a strong tensile force. is relatively small, and the application of the necessary force may cause the material to be cut from the clamping portion or the clamping portion may be damaged. Therefore, the allowable tensile force must be reduced,
There was a problem in that there were restrictions on the amount of machining at one time using a hole die or roller die, or restrictions on the number of tandems such as roller dies.

(Problems to be improved by invention) Even in the above-mentioned crawler-type clamping device, increasing the clamping pressure not only causes an increase in the moving friction force of the crawler belt members, but also the pressurizing force causes the chain members to join together. Caught on a pin (for example, Jitsukō No. 50-5995,
(Utility Model Publication No. 51-29909) cannot withstand strong external forces, so when a strong tensile force is required, such as during wire drawing, not only is there a limit to the amount of processing at one time, but each part Problems often occurred in the structure of the

An invention in which the belt is supported by pinch rollers has also been proposed (Japanese Patent Application Laid-Open No. 123157-1983).
No.), because there is no intervening chain formed so that the contact surface is horizontal, the average transmission of pressure force is insufficient, and the rollers roll in a fixed position.
There was a problem that the pressurizing force transmission part fluctuated during pressurization.

That is, in this invention, a set of annular chains are installed in parallel to each other in a straight line to form a clamping part, and the chains are formed so that the sides in contact with the pressure roller are on the same plane when moving in a straight line. A part of an annular elastic clamping band that moves at the same speed as the chain is attached to the clamping side of the chain of the clamping part,
A pressure roller is installed behind the chain of the clamping portion so as to be able to roll freely with one side of the pressure roller in contact with the chain, and the pressure roller can roll on the pressure member as the chain moves. It has been erected with guidance. Further, the pressure-resistant member is made of a special steel plate and is fixed to the guide plate. The elastic strap mentioned above is made of a material that is strong, has high weather resistance, and has a large elastic limit, such as urethane-based synthetic rubber. Further, one or both of the annular chains can be moved toward and away from each other, and the clamping pressure of the clamping portion can be adjusted.

However, P: Pressure force 20000Kg l: Pressure length mm (thickness x total number x number of rollers) The number of rollers (10 mmφ) is the number arranged in a line of 500 mm. E and E are the Young's moduli of R 1 and R 2 , R 1 is the radius of the small roller (5 mm), and R 2 is the radius of the large roller. However, in this case, the large roller is straight, so R 2 is calculated as 2×R 1 . Therefore, when calculating the Hertzian stress, As mentioned above, even if a length of 500 mm supports a reaction force of 20 tons, the Hertzian stress is
It becomes 139.8Kg/mm. This value is close to the value allowed for normal roller bearings,
This shows that it can be carried out without difficulty in practice.

Therefore, the strong pressing force is applied to the clamping belts 10, 28.
It is transmitted as is, except for the modification. Further, as the drive wheels 7, 24 rotate in the directions of arrows 41, 42, the chains 8, 25 also rotate in the directions of arrows 43, 42.
4 and pull out the steel wire 39 in the direction of arrow 45, each pressure roller 14, 31
rolls along the outer circumferential side of the pressure-resistant member toward the arrow 45 side on the clamping side, so the movement friction of the chains 8, 25 becomes extremely small (due to rolling friction), and the tensile force generated by the drive wheels 7, 24 is reduced. This can be efficiently converted into tensile force of the steel wire 39. Furthermore, as shown in FIG. 3, the clamping belts 10, 28 that receive the pressure are deformed and protrude toward the chain, so the contact friction between the chains 8, 25 and the clamping belts 10, 28 increases. However, there is no risk of slippage occurring between the two.

(Effect of the invention) That is, according to this invention, since the clamping belt is attached to the chain to form the clamping surface, there is an effect that the chain can be gripped reliably and moved accurately. In addition, since the pressing force of the chain is received by the pressure roller and further by the pressure resistant member, a large pressing force can be applied equally to each part, and there is no risk of locally uneven pressure occurring due to deformation of the chain etc. Furthermore, since a pressure roller is used, the frictional force of moving the chain can be significantly reduced.
