[0002] Chinese Patent 202123240129.4 discloses a multifunctional punching and shearing machine. By setting up square, round and right-angle openings, the cutter can cut multiple square, round and right-angle irons under the push of an electric telescopic rod, thereby achieving the multifunctional effect of the punching and shearing machine. However, the punching and shearing machine in the prior art cannot be height-adjusted, which makes it inconvenient for workers of different heights to use it. Therefore, it is urgent to design a multifunctional punching and shearing machine to solve the above problems, but the above-mentioned multifunctional punching and shearing machine adjusts the height of the shell by manually turning the handwheel. However, this adjustment method has some inconveniences. First, manually turning the handwheel requires a certain amount of physical strength and labor, which is a certain burden for the operator. Secondly, the process of turning the handwheel is relatively cumbersome, and the handwheel needs to be turned repeatedly until the desired height is reached, which is time-consuming and labor-intensive. Therefore, a multifunctional punching and shearing machine is proposed to solve the above problems. Utility Model Content

[0003] In view of the deficiencies existing in the prior art, the utility model provides a multifunctional punching and shearing machine, which solves the problem in the prior art that the height of the punching and shearing machine can only be adjusted by manual rotation, thereby reducing the operating burden on workers.

[0005] The technical principle of the utility model is: the multifunctional punching and shearing machine is mounted on the mounting frame, and then the lifting device is started as needed when in use, first the double-headed motor is started, the motor drives the first transmission shaft to rotate, and drives the second transmission shaft to rotate through the gear commutator, thereby driving the transmission gear, and then the transmission gear drives the bevel gear to roll, so that the lead screw in the hollow sleeve moves up and down, and the height of the mounting frame is adjusted. At the same time, after adjusting the appropriate height, the telescopic support device plays a good supporting role, which is used to support and fix the multifunctional shearing machine.

[0006] Compared with the prior art, the utility model has the following beneficial effects: by providing a double-headed motor, a gear commutator, multiple sets of telescopic support devices and other devices, the multifunctional punching and shearing machine does not need to be manually adjusted when adjusting the height, thereby solving the problem that the prior art needs to rely on manual height adjustment, which is cumbersome, time-consuming and labor-intensive. In summary, due to the above improvements made in the utility model, the multifunctional hydraulic press has the beneficial effect of electric height adjustment, which saves time and effort.
