Abstract
The utility model discloses a roll shaft braking device for a rolling forming machine, comprising a braking wheel, and upper and lower pressure frames which are semicircular and used for enclosing the braking wheel, wherein the upper pressure frame is hinged with one end of the lower pressure frame; a crank is arranged at the end of the lower pressure frame hinged with the upper pressure frame and arranged on a frame, a pressure frame enclosure tension regulating device is arranged at the other end of the lower pressure frame corresponding to the upper frame; rubber pieces are arranged among the upper and lower pressure frames and the braking wheel; and the braking wheel is sleeved on a roll shaft on the upper part of the rolling forming machine and connected with the arbor through a flat key. During the normal working of the rolling forming machine, the roll shaft rotates to overcome the friction between the braking wheel and the rubber pieces, as a result, when the roll shaft is not driven, the friction between the braking wheel and the rubber pieces helps overcome the inertia from the rotation of the roll shaft and a gear to protect the gear from damage and prolong the service life of the gear.
Description
Technical field
The utility model relates to a kind of rolling and prolongs make-up machine, particularly a kind ofly is used to roll the roll shaft brake apparatus that prolongs make-up machine.
Background technology
Existing rolling prolonged the rollforming machine that forming machine mainly is made up of frame, main motor, transmission mechanism and upper and lower roll body.On upper and lower roll shaft, be provided with the roll forging mould; to prolong machine roll shaft rotation generally be to adopt gear transmission mode owing to roll, and rolls and prolong machine when operation finishes powered-down, and gear rotates owing to there is inertia to exist; regular meeting causes damage to tooth in the time of then, has reduced the service life of gear.
Summary of the invention
The utility model has overcome above-mentioned the deficiencies in the prior art, provides a kind of and can effectively protect gear, prolongs the roll shaft brake apparatus of service life of gear.
The technical solution of the utility model is achieved in that
Be used to roll the roll shaft brake apparatus that prolongs make-up machine, described brake apparatus comprise braked wheel and two be semi-round ring shape in order to surround braked wheel on, press down frame, last pressure frame is hinged with an end that presses down frame, press down on the frame with on press this hinged end of frame also to be provided with a crank, described crank is installed on the frame, be provided with the pressure frame at the last pressure frame and the other end that presses down frame and surround slack adjuster, last, press down between frame and the braked wheel and be provided with sheet rubber, described braked wheel be set in roll on the roll shaft that prolongs make-up machine top and with the roll shaft on top between link to each other by flat key.
As preferably, described pressure frame surrounds slack adjuster and comprises bolt, last pressure frame respectively is provided with a connecting ring with the other end that presses down frame, attaching nut behind two connecting rings of screw bolt passes, on bolt, be arranged with successively and compress handwheel, stage clip, compress the handwheel two ends and offset with an end of bolt head and stage clip respectively, the other end and the connecting ring of stage clip offset.Thereby can be by the size of adjusting handle to stage clip pressure, the frictional force of regulating between sheet rubber and the braked wheel is the size of brake force.
Adopted the beneficial effects of the utility model of technique scheme to be: to roll and prolong machine when operate as normal; roll shaft is that the frictional force that overcomes between braked wheel and the sheet rubber is rotated; so when roll shaft loses driving force; the inertia that frictional force between braked wheel and the sheet rubber produces when helping to overcome roll shaft and gear rotation; the protection gear; make it avoid infringement, prolong its service life.
