Description
Technical Field
The utility model relates to a double fixing device for hook wedge key positioning and hot-set stud connection of a support arm and a cross beam, which can be widely applied to a double-disc friction press.
Background
The existing double-disc friction press is unstable in connection structure of the hook head support arm and the hook head cross beam, impact and vibration can be generated in the forging working process, nuts at the joint of the hook head support arm and the hook head cross beam of the double-disc friction press are easy to loosen, torque generated during rotation of a flywheel acts on the hook head support arm, dislocation is generated at the joint of the hook head support arm and the hook head cross beam of the double-disc friction press, normal operation of equipment is affected, and potential safety hazards are generated.
Disclosure of Invention
The utility model aims to provide the double fixing device for the hook wedge key positioning and the hot-set stud connection of the support arm and the cross beam, which has the advantages of reliable looseness prevention, good positioning, torsion prevention, shearing resistance, impact resistance and reliable connection and fastening.
In order to achieve the purpose, the double fixing device for hook head wedge key positioning and hot-set stud connection of the support arm and the cross beam comprises a hook head cross beam with a straight hook head arranged on the side surface of the upper part, a hook head support arm provided with an inclined hook head and mutually embedded with the straight hook head and the inclined hook head, a fastening wedge key inserted between the straight hook head and the inclined hook head, a plurality of central hole heating studs in threaded connection with the hook head cross beam and the hook head support arm, and nuts for fastening the central hole heating studs on the hook head cross beam and the hook head support arm through threaded connection and back nuts fastened on the central hole heating studs through threaded connection and compressing the nuts.
The utility model relates to a double fixing device for hook wedge key positioning and hot-set stud connection of a support arm and a cross beam, which has the following working principle:
firstly, in the installation process of a central hole heating stud, the central hole heating stud is connected with a hook head cross beam and a hook head support arm in a threaded manner, and nuts are screwed; then, the heating pipe is placed in the central hole of the central hole heating stud, the central hole heating stud is electrified, and after heating, the central hole heating stud stretches. The extension of the stud is heated through the central hole, the pre-tightening force can be controlled, when the extension of the stud meets the requirement, the nut is screwed down again, the nut is fastened at the same time, the pre-tightening force is generated after the central hole heats the stud and is cooled, the hook head cross beam is connected and fastened with the hook head support arm of the hook head, and the loosening of the nut caused by vibration is avoided. Therefore, the pre-tightening and anti-loosening effects of the nuts are realized, and the anti-loosening is reliable.
Secondly, the double-disc friction press is in the course of the work, and the flywheel is rotatory to produce moment of torsion, transmits on the gib head support arm through the friction disc, and the fastening wedge key is installed between gib head and gib head support arm inclined plane gib head of gib head crossbeam straight face, through fastening wedge key both sides face close fit, plays the positioning effect, has avoided producing the dislocation because of gib head support arm and gib head crossbeam faying face under the effect of moment of torsion, bears torsional force, the shearing force that are used in on gib head support arm to and the impact force that produces on the gib head support arm when friction disc and flywheel lean on the dish. Therefore, the positioning is good, the torsion is prevented, the shearing is resisted, and the impact is resisted.
The double fixing device for hook wedge key positioning and hot-set stud connection of the support arm and the cross beam adopts a hook and wedge key integrated positioning and connecting structure and a double-nut fastened central hole heating stud connecting structure, and the hook support arm and the hook cross beam are reliably connected and fastened.
In summary, the double fixing device for the hook wedge key positioning and hot-set stud connection of the support arm and the cross beam is reliable in looseness prevention, good in positioning, torsion-proof, shearing-resistant, impact-resistant and reliable in connection and fastening.
Drawings
The utility model will be further described with reference to the accompanying drawings and examples.
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a left side view of fig. 1.
Description of the embodiments
In fig. 1 and 2, the double fixing device for hook wedge key positioning and hot-set stud connection of the support arm and the cross beam comprises a hook cross beam 1 with a straight hook head a arranged on the side surface of the upper part, a hook head support arm 2 provided with an inclined hook head b and mutually embedded with the straight hook head and the inclined hook head, a fastening wedge key 3 inserted between the straight hook head and the inclined hook head, a plurality of central hole heating studs 4 in threaded connection with the hook cross beam and the hook head support arm, nuts 5 for fastening the central hole heating studs on the hook cross beam and the hook head support arm through threaded connection, and back nuts 6 for fastening the central hole heating studs on the central hole heating studs and compressing the nuts through threaded connection.
The above-mentioned double fixing device for hook wedge key positioning and hot-set stud connection of the support arm and the cross beam is only a preferred embodiment of the present utility model, but the present utility model is not limited to the above-mentioned preferred embodiment, and although the present utility model has been described above by way of example, it should be understood that it is not limited to the above-mentioned preferred embodiment, and any person skilled in the art may make some changes or modifications to equivalent embodiments without departing from the scope of the present utility model, but any simple modification, equivalent substitution and improvement made to the above-mentioned embodiment according to the technical spirit and principle of the present utility model still falls within the scope of the present utility model.
