Embodiment Construction
[0014] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] It can be seen from the drawings that the implicit series energy-saving cylinder of the present invention includes a fixed part 1 and a moving part 2 . The fixed part 1 mainly includes a fixed cylinder 11 and a piston-piston rod assembly 12 ; the moving part 2 mainly includes a moving cylinder 21 and a force output terminal 22 . The outer surface of the moving cylinder 21 cooperates with the inner surface of the fixed cylinder 11 to slide relatively; the inner surface of the moving cylinder 21 cooperates with the outer surface of the piston-piston rod assembly 12 to slide relatively. The piston rod assembly 12 is hidden in the moving cylinder 21; the above-mentioned cooperation between the fixed part 1 and the moving part 2 forms a rear air chamber 3 for providing thrust, a front air chamber 5, and an intermedi...

The invention discloses an energy-saving concealed tandem cylinder, aiming at solving the problems of overlarge longitudinal dimension, an overlong pull rod, poor overall structural rigidity, high return energy consumption and high impact noise of an existing energy-saving unconcealed tandem cylinder. The energy-saving concealed tandem cylinder is characterized in that a cylinder body serves as a moving component, and a fixed piston-piston rod component is concealed inside the cylinder body to form a front air chamber and a back air chamber for providing push force and a middle air chamber for providing return force. The energy-saving two-stage concealed tandem cylinder has the advantages that the longitudinal dimension of the energy-saving two-stage concealed tandem cylinder is about half of that of an existing two-stage unconcealed tandem cylinder, and accordingly the energy-saving two-stage concealed tandem cylinder is high in structural rigidity and low in manufacturing cost; since the energy-saving two-stage concealed tandem cylinder is only provided with the return air chamber with small cross section area, return energy consumption, impact force and noise are reduced remarkably; the energy-saving two-stage concealed tandem cylinder is capable of achieving three-stage force output and further increasing cylinder load rate so as to be more beneficial to energy saving.
Description
technical field [0001] The invention relates to the field of cylinders, and mainly relates to an implicit serial energy-saving cylinder. Background technique [0002] Tandem cylinders are commonly known as double force cylinders. There are two advantages of adopting series cylinders: (1) It can avoid the excessive increase of the bore and the sharp increase of the manufacturing cost. For example, two tandem cylinders with a bore diameter of φ320 have an output force equivalent to one cylinder with a bore diameter of φ450, and its manufacturing cost is much lower than the latter. (2) Cylinders in series can carry out graded force output. For example, two-stage series cylinders can make two cylinders work at the same time, or only one cylinder can work according to the required output force. Therefore, the phenomenon of "big horses and small carts" can be alleviated to a certain extent, the redundancy of thrust and system pressure can be reduced, and the load rate of the cy...
