Quick connecting device

Technical Field

The utility model belongs to the technical field of, concretely relates to quick connecting device.

Background

At present, in the metal forging industry, a multi-station die is often needed to perform die forging forming on a product, and each station is basically designed and arranged side by side. In order to ensure that the pressure center of the multi-station die is positioned at the pressure center of the press machine when the multi-station die works, the eccentric load of the press machine is avoided, and the service life of equipment is shortened. A driving oil cylinder 3 is generally installed between two upright posts 2 on the side surface of a press machine 1 (as shown in fig. 1 and 2), a piston rod 4 of the driving oil cylinder 3 is connected with a lower template 7 of a multi-station die through a joint plate 5 and a screw 6, and the die change among multiple stations is realized by controlling the driving oil cylinder 3. Because the product variety is more, and the multistation mould is changed frequently, when changing the multistation mould, must unpack driving cylinder piston rod 4 and lower bolster 7 earlier, connect driving cylinder piston rod 4 and lower bolster 7 after the mould is changed.

Under the prior art, a joint plate 5 is fixed on a piston rod, connecting holes are formed in four corners of the joint plate 5, and screw holes are formed in the corresponding positions of the lower template of the multi-station die in a connecting mode. When the die is replaced, an operator needs to drill between two side uprights 2 of the press machine, screws 6 at four angular positions of a joint plate 5 are removed, a piston rod 4 is retracted, a workbench of the press machine 1 is longitudinally moved out, the die replacement is completed by using a crane, after the die replacement is completed, the workbench of the press machine 1 is moved back to a working position, the piston rod 4 is extended by a driving oil cylinder 3 to enable the joint plate 5 to be in contact with a lower die plate 7, and the operator drills between the two side uprights of the press machine again to screw four bolts.

The disadvantages are that: the distance between two upright posts 2 on the side surface of the press machine is about 900mm, and the driving oil cylinder 3 is arranged between the two upright posts 2 on the side surface of the press machine, so that the operating space for dismounting the screw 6 of the joint plate 5 by an operator is less than 400mm, and the dismounting working condition is poor. On the other hand, the joint plate 5 is fixed on a piston rod of the driving oil cylinder, the screws 6 at four corners are close to the piston rod 4, the wrench can only rotate 1/3 circles when screwing or loosening, and the screws 6 are horizontally arranged, so that time and labor are wasted when an operator performs construction, the time for changing a mold to screw or loosen the screws is about 10-15min, and the efficiency is low. In order to solve the problems, a set of connecting device which can be quickly connected and is easy and convenient to operate needs to be designed, so that the driving oil cylinder piston rod 4 and the lower template 7 are convenient and efficient to disassemble and assemble, the construction difficulty of operators is reduced, and the clamping efficiency is improved.
