The invention relates to a device for opening pressed products, in particular for removing gears pressed on the end of the shaft of the traction motor of a locomotive.

Known stand for mounting and demounting press compounds containing a platform installed on the mechanism repressive made in the form of the power cylinder is placed coaxially with him capture in the form of mobile arcs (see the patent of Russia 2003452, 23 P 19/02).

The disadvantage of this device is the inability to extinguish the jet impact repressive due to the absence of the damper mechanism, and the availability of manual operations required for rendezvous and capture circuit arcs.

It is also known a device for opening pressed products containing mounted in guides on the fixed base cart, mounted on the trolley pick up the body in the form of two C-shaped brackets mounted movably by means of hydraulic cylinders, rigidly connected to the gripper body hydraulic power to remove supressive the wheel base (see USSR author's certificate 1761429, 23 P 19/02).

In this device, which is the closest to the claimed, to ensure alignment of the parsed product relative power of the hydraulic drive includes a lifting mechanism of the hydraulic drive and rigidly associated gripper body, which complicates the design and reduces the reliability. Since the C-shaped bracket gripper body with their ends attached to the stem of the two parallel current drive cylinders, in case of violation of the synchronization of their actions, this can lead to jamming. In addition, since the damping reactive power repressive this device has two parallel active damping cylinders arranged on opposite sides of the power hydraulic drive, it also does not preclude jamming and reduces the reliability of the device.

The technical result of the claimed device for opening pressed products is the elimination of the parallel action of the actuating cylinders and improve reliability of the device.

This technical result is achieved in that the device for disassembly of moulded articles containing the set in the direction, the plant is movable by means of hydraulic cylinders, rigidly connected to the gripper body hydraulic power for removing moulded articles and auxiliary damper cylinder connected to the hinge shaft with the carriage and the housing to the fixed base, a C-shaped bracket gripper body mounted with their ends in the horizontal rails of the frame and each of them is fastened with the middle part of the stem of a separate hydraulic cylinder, mounted horizontally on the frame, an auxiliary damper cylinder is located below the truck in the vertical plane of symmetry and parallel to the horizontal longitudinal axis of the power hydraulic actuator, on the fixed base includes a table with stowage for fixing the parsed items coaxial power the hydraulic drive. In addition, a table with stowage for fixing the parsed items are pivoted by means kinematically associated with a rotation mechanism.

Comparative analysis of the prototype shows that the proposed device for opening pressed products differs in that the C-shaped bracket gripper body mounted with their ends in the horizontal rails of the frame and each of them is fixed damping cylinder is located below the truck in the vertical plane of symmetry and parallel to the horizontal longitudinal axis of the power hydraulic actuator, on the fixed base includes a table with stowage for fixing the parsed items coaxial power the hydraulic drive. In addition, a table with stowage for fixing the parsed items are pivoted by means kinematically associated with a rotation mechanism. This difference from the prototype allows to assert the consistency of the proposed solutions to the patentability criteria of "novelty". The comparison of the proposed device is not only the prototype, but also with other technical solutions in this field of technology is not allowed to reveal any sign, similar distinctive signs, which enables to make a conclusion on compliance with the conditions of patentability of an invention - "inventive step".
