4results about How to "Automatic ejection" patented technology

A pipe bending ejection device is disclosed, comprising a positioning mechanism that clamps and fixes the pipe fitting, a bending mechanism that bends the pipe fitting after clamping it, and an elastic ejection mechanism that ejects the bent pipe fitting from the positioning groove. During the bending process of the pipe bending machine, the elastic potential energy of the spring in the elastic ejection mechanism increases. After the pipe fitting is bent, when the clamping of the pipe fitting is released, the elastic potential energy of the spring in the elastic ejection mechanism is released, ejecting the bent pipe fitting, causing it to fall from the positioning groove and be collected. It is convenient and efficient to use, can automatically eject the bent pipe fitting, has stable performance, and eliminates the need for manual removal of the bent pipe fitting from the positioning groove or the use of a hydraulic telescopic cylinder to push the bent pipe fitting out of the steel pipe positioning groove. Compared with the existing technology, it has superior advantages.

This utility model relates to the field of fixation frame technology and discloses a stem cell cryopreservation tube anti-tipping fixation frame, including a support cylinder, with placement frames movably connected to both ends of the support cylinder. The center line of the placement frames and the center line of the support cylinder are on the same vertical plane. The interior of the placement frames is provided with a support structure for supporting the cryopreservation tubes. This stem cell cryopreservation tube anti-tipping fixation frame includes a mounting bracket, a fixing ring, a lifting plate, a fixing groove, and a rubber pad. When placing the cryopreservation tube, it is inserted into the fixing ring from the top, passing through the fixing ring and then into the fixing groove. The fixing groove, in conjunction with the fixing ring, supports the cryopreservation tube to ensure its stability. The rubber pad inside the fixing groove provides cushioning and anti-slip effects, preventing vibration of the cryopreservation tube and improving its stability after placement. This solves the problem of ineffective support for cryopreservation tubes.

The utility model discloses a horizontal parting core making device concretely relates to foundry core making field, and including frame and two installation on core shooter core box fixing frame, the outer top surface fixed mounting of frame has the fixed plate, the outer bottom surface fixed mounting of fixed plate has the drive cylinder, the outer top surface fixed mounting of fixed plate has two lift guide rods. The utility model discloses a horizontal parting core making device, in actual work, drive cylinder drives the core box of installing core to descend, and the moving plate is along two lift guide rods and is descended, and two outer top core rods will pass through two guide holes and contact with the support plate, and then will push the support plate and ascend along the movable rod, and extrude the first spring, and two inner top core rods will ascend from the inside of core box, to eject the core in the core box, to separate the core box with the upper core box by drive cylinder, alleviate the labor intensity of artificial, and realize the core ejecting automatically, improve production efficiency.
