Abstract
The invention relates to a nitrogen spring, in particular to a directional anti-rotating nitrogen spring. The directional anti-rotating nitrogen spring consists of a cylinder barrel, a guide seat, a piston rod and a sealing piece, wherein a guide groove is formed in the inner wall of the cylinder barrel, and a boss matched with the guide groove in the inner wall of the cylinder barrel is arranged at one end of the piston rod. By adopting the technical scheme provided by the invention, when the nitrogen spring works, the piston rod and the cylinder barrel can be prevented from relatively rotating, the piston rod can be guaranteed to linearly move in the cylinder barrel, the orientation of the nitrogen spring can be effectively guaranteed, the piston rod and the cylinder barrel are prevented from relatively rotating, thus the use stability of a die is guaranteed, quality accidents are prevented from occurring, the safety of the die is improved and the service life of the die is prolonged.
Description
Technical field
The present invention relates to a kind of nitrogen spring, especially relate to a kind of directed rotation inhibiting nitrogen spring.
Background technique
Nitrogen spring is a kind of parts with spring function, can conventional elastic means be replaced, complete the work that conventional elastic means has been difficult to, there is the performance not available for conventional elastic means, nitrogen spring not only can be applied widely in die industry, also can be applied to other industrial fields.It is primarily of compositions such as cylinder barrel, guide holder, piston rod and Sealings.At present, in the structural design of nitrogen spring, piston rod and cylinder barrel have positioning device at above-below direction, but do not have positioning device at circumferencial direction, therefore, there is possibility in relative rotation between piston rod and cylinder barrel, as occurred relatively rotating, then affecting the stability of mould, mould is caused normally to work, to such an extent as to initiation Accident due to quality, cause heavy losses economically, even cause security incident.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of nitrogen spring in the course of the work, the directed rotation inhibiting nitrogen spring that piston rod and cylinder barrel can not relatively rotate.
Above-mentioned technical problem of the present invention solves by providing a kind of directed rotation inhibiting nitrogen spring of following structure, this directed rotation inhibiting nitrogen spring is made up of cylinder barrel, guide holder, piston rod and Sealing, described inner wall of cylinder is provided with direction recess, one end of described piston rod is provided with the boss matched with inner wall of cylinder direction recess, during nitrogen spring work, remain that piston rod is along moving linearly in cylinder barrel, can not relatively rotate between piston rod and cylinder barrel.
Compared with prior art, because inner wall of cylinder of the present invention has set up direction recess, piston rod one end is provided with the boss matched with inner wall of cylinder direction recess, make can not relatively rotate between piston rod and cylinder barrel, and ensure that piston rod is along moving linearly in cylinder barrel, the stability that mould uses can be ensured well, avoid the generation of Accident due to quality, increase the Security of mould, extend the mold use life-span.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the cross-sectional schematic along A-A direction.
Embodiment
Anti-rotating nitrogen spring of the present invention as shown in Figure 1 and Figure 2, guide holder 2 is contained on piston rod 1, then load in cylinder barrel 3, described cylinder barrel 3 inwall is provided with direction recess 4, described piston rod 1 is provided with the boss 5 matched with cylinder barrel 3 inwall direction recess 4, boss 5 on piston rod 1 is embedded in the direction recess 4 of inner wall of cylinder, is filled with nitrogen in cylinder barrel 3.
When the present invention works, piston rod 1 along direction recess 4 moving linearly in cylinder barrel 3, and can not relatively rotate between piston rod 1 and cylinder barrel 3, effectively can ensure the orientation of nitrogen spring and prevent relatively rotating of piston rod and cylinder barrel.
Claims (1)
1. a directed rotation inhibiting nitrogen spring, be made up of cylinder barrel (3), guide holder (2), piston rod (1) and Sealing, it is characterized in that: cylinder barrel (3) inwall is provided with direction recess (4), piston rod (1) is provided with the boss (5) matched with cylinder barrel (3) inwall direction recess (4), and the boss (5) on piston rod (1) is embedded in the direction recess (4) of inner wall of cylinder.
