Embodiment Construction

[0011] The present invention is arranged between the output chambers of the proportional reversing valves A and B of each kinematic pair, including:

[0012] Relief valve one 1 connected with chamber A, check valve one 2 connected with relief valve one 1; and relief valve two 3 connected with chamber B, one-way valve two 4 connected with relief valve two 3;

[0013] The output chamber of the one-way valve 1 is connected to the B chamber, and the output chamber of the one-way valve 4 is connected to the A chamber;

[0014] An oil passage 5 leading to the oil tank is provided between the relief valve one 1 and the one-way valve one 2 and between the two relief valve 3 and the one-way valve 4 .

[0015] When chamber A is pressed down by the forging hammer or high pressure is generated by motion inertia, the oil returns to chamber B from relief valve 1 through check valve 2, and a small part returns to the oil tank through oil circuit 5, so as to achieve unloading and The role of...

Abstract

The invention relates to a safety protection system of a forging system efficient overloaded operation robot. The safety protection system is arranged between an output cavity A of a proportional reversing valve of all kinematic pairs and an output cavity B of the proportional reversing valve of all the kinematic pairs. The safety protection system comprises a first overflow valve connected with the cavity A, a first check valve connected with the first overflow valve, a second overflow valve connected with the cavity B and a second check valve connected with the second overflow valve, wherein an output cavity of the first check valve is connected with the cavity B, an output cavity of the second check valve is connected with the cavity A, and oil ways which are communicated with an oil tank are arranged between the first overflow valve and the first check valve and between the second overflow valve and the second check valve respectively. Oil can be discharged through the overflow valves when oil pressure overpressure occurs in any cavity of a buffer cylinder, most of oil in one of the cavities of the buffer cylinder flows into another cavity in the buffering process, and therefore the unloading effect and the shock absorption effect are achieved.

Description

technical field [0001] The invention relates to a safety protection system for a high-efficiency heavy-duty operation robot of a forging system. Background technique [0002] In the heavy-duty forging system, due to the high impact pressure, if the load is exceeded, it is easy to cause damage to the equipment; therefore, it is necessary to provide a safety protection system during use to avoid this phenomenon. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency heavy-duty operating robot safety protection system for a forging system that can achieve good protection for the manipulator. [0004] For this reason the technical scheme that the present invention adopts is: the present invention is arranged between the proportional reversing valve A of each kinematic pair, B output cavity, comprises: [0005] Relief valve one connected with chamber A, check valve one connected with relief valve one; and relief valve two connec...
