Description

The invention relates to the cold treatment of metals and can be used to feed a lengthy material into the working area of a press.

A device for transporting material is known, comprising a plate supported on pillars, axes with asterisks, covered by a chain conveyor, carrying links with protrusions for accommodating material. The conveyor is driven from the drive. Press through chain drive and crank-lever mechanism 1.

A disadvantage of the known device is the low accuracy of the pitch when moving long material.

The closest to the proposed by the signs and the achieved effect is a device for moving the material, containing a drive-based flexible closed traction body, gripping bodies connected to the body mounted on the traction body and carrying spring-loaded clamping jaws set in motion in the direction perpendicular to the feed direction of the material, through the rollers fixed on them from copiers located symmetrically on the base with respect to the feed direction 2.

The disadvantages of the known device are low reliability of operation and feeding accuracy.

1Invention of the invention - improving the reliability of work and accuracy of supply.

This goal is achieved by the fact that the device for moving a long-dimensional material containing installed HijiH on the basis of a drive flexible closed traction organ, grasping organs connected with a housing mounted on the traction organ and carrying spring-loaded clamping jaws movement in the direction perpendicular to the direction of the material feed, through rollers mounted on them from copiers, located on the base symmetrically with respect to the feed direction, the clamping jaws are made in the form of wedges, mustache mounted in the housing with the ability to move in the direction of movement of the traction body and are equipped with a movement mechanism in the direction opposite to the feed direction.

The mechanism for moving the clamping jaws is made in the form of a two-armed lever hinged on the base from the side of the material supply, which interacts with one end to the ends of the clamping jaws and is connected to the other end through the spring with the base.

The device is provided with a guide for moving the material.

Copiers are made in the form of closed grooves having straight and curved sections.

Traction body is made in the form of a chain.

A device for feeding a lengthy material to the treatment area contains (base) body 1, in which a drive sprocket 3 is installed with the aid of a drive shaft 2, and a sprocket 5 with the aid of a shaft 4.

Sprockets 3 and 5 enclose an endless chain 6, carrying gripping bodies having a body 7 with a tapered bore 8, clamping jaws 9 and 10 installed in a hole with the possibility of rotation around an axis parallel to the feed direction, and spring-loaded springs 11.

Levers 12 are fixed on jaws, non-carrying rollers 13. On plate 1 (base) plates 14 and guide 15 are fixed,

5 is located above the chain b, and stops 16 are fixed on the jaws.

Position 17 marked material (circle, wire).

In the side walls of the housing 1 (base), closed copy grooves are made, having straight sections a and b and curved sections c. The rollers 13 are located in the copy grooves.

On the guide 10, an axis 18 is installed, carrying a double-arm lever 19, and a spring 20 fixed at one end, connected by the other end to the upper end of the lever 19.

The outer surfaces of the jaws are made with a radius RI Rj, RS (FIGS. 6, 7 and 8) along the entire length of the generator. Rotation axis

jaws offset from the axis of the material feed by the value of h.

The device works as follows.

The material 17 is fed into the clamping jaws 9 and 10 along the guide 15. With the rotation of the chain 6, the rollers 13 move along a curvilinear section 8, the clamping jaws 9 and 10 are separated and do not clamp the material. 17. When the rollers move along the rectilinear section of the jaws 9 and 10, the turns are in a plane perpendicular to the feed axis of the material 17 and the material 17 is clamped. Then the stops 16 interact with the end of the two shoulders lever 19 and the clamping jaws 9 and 10 move in the opposite direction filing .ma5 materiala 17, stretching the spring 11.

The effect of using the device is to increase the reliability of operation and the accuracy of the feed.
