Description

Improved generation response diathermanous equipment bar guider

[ technical field ]

The utility model belongs to the technical field of the diathermanous equipment technique of response and specifically relates to an improved generation response diathermanous equipment bar guider.

[ background art ]

In the actual heating production before forging, an induction diathermy device is often used.

On the one hand, the metal bar can obtain enough forward clamping force from the bar guiding device, so that the metal bar can be smoothly absorbed completely through induction, on the other hand, the clamping force cannot be too large, and the excessive clamping force can leave marks on the surface of the metal bar to influence the quality of a final forged piece.

The conventional bar stock guide consists of a pair of pinch rolls and cylinders arranged horizontally. The pinch roll is driven to rotate by an independent speed reducing motor to provide friction force for forward conveying of the bar, and the pressing force provided by the air cylinder needs to ensure that the friction force of the pinch roll is large enough to drive the metal bar to advance. However, after the bar guide works for a period of time, the cylinder cannot guarantee sufficient clamping force due to long-term reaction of the metal bar, or the clamping forces on the two sides cannot guarantee consistency, so that the whole bar guide cannot provide sufficient friction force, and the pinch roll cannot convey the metal bar forwards due to slipping.
