Detailed Description
In order that those skilled in the art may better understand the technical solutions of the present utility model, the following detailed description of the present utility model with reference to the accompanying drawings is provided for exemplary and explanatory purposes only and should not be construed as limiting the scope of the present utility model.
Example 1:
as shown in fig. 1-4, a delay recovery device of a nitrogen spring comprises a nitrogen spring 1, a piston rod 2 is movably arranged in the nitrogen spring 1, the delay recovery device is arranged in the nitrogen spring 1 and comprises a ventilation guide plate 4 adapted to the inner wall of the nitrogen spring 1, ventilation holes are formed in the ventilation guide plate 4 in a penetrating mode, the ventilation guide plate 4 is fixedly arranged on part of the outer wall of an inner cavity of the nitrogen spring 1, a mounting seat 3 is fixedly arranged at the lower end of the ventilation guide plate 4 on the outer wall of the piston rod 2, a one-way valve 6 communicated with the inner cavity of the nitrogen spring 1 is arranged in the mounting seat 3, and an overflow valve 7 communicated with the inner cavity of the nitrogen spring 1 is arranged in the mounting seat 3 at intervals.
The specific working principle is as follows: when the device works, the piston rod 2 in the nitrogen spring 1 is stressed and starts to move under the influence of external force such as a mould, the piston rod 2 drives the mounting seat 3 and the ventilation guide plate 4 to descend from the uppermost end, gas in the inner cavity of the nitrogen spring 1 in the descending process flows to the upper cavity through the one-way valve 6 and the overflow valve 7 and is very fast close to balance, after the piston rod 2 drives the mounting seat 3 and the ventilation guide plate 4 to move to the bottommost part, the one-way valve 6 is closed, the piston rod 2, the mounting seat 3, the ventilation guide plate 4 and the like slowly ascend to the uppermost part together under the action of the overflow valve 7, and because the gas in the upper and lower parts of the inner cavity of the nitrogen spring 1 cannot be very fast balanced under the action of the overflow valve 7. In the process, the device reduces the time (delay recovery) of the mutual contact between the die and the nitrogen spring 1, thereby reducing the wear of the die and the nitrogen spring 1; meanwhile, the delay recovery device (the mounting seat 3, the ventilation guide plate 4 and the like) is arranged inside the nitrogen spring 1, so that the structure of the nitrogen spring 1 is more compact and reasonable, and the use is more convenient.
