SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides an overload protection just removes transshipping easy hydraulic pressure overload protection device.
The utility model provides a technical scheme:
the hydraulic overload protection device comprises a rack, a plurality of stand columns, a hydraulic cylinder, a locking nut and a ram, wherein the stand columns are installed on the rack, and the hydraulic cylinder penetrates through the stand columns and is installed between the ram and the locking nut.
The stand quantity is four, the stand is located the four ends of frame respectively.
The hydraulic cylinder comprises a cylinder body lining and a hydraulic cylinder piston, the hydraulic cylinder piston is arranged on the top of the ram, and the cylinder body lining is located between the locking nut and the stand column.
The diameter of the upper end part of the upright post is smaller than that of the lower end part of the upright post, and the cylinder body bush is annularly arranged on the upper end surface of the lower end part of the upright post.
The exhaust hole is arranged above the cylinder body and is provided with a screw plug.
And a sealing gasket is arranged between the screw plug and the emptying hole.
The locking nut side is equipped with the through-hole, the through-hole install holding screw.
Has the advantages that:
the hydraulic cylinder with overload protection penetrates through the upright post and is arranged between the ram and the locking nut, and the locking nut is limited by the cylinder body bush, so that the nut keeps unchanged relative to the position of the upright post and can be in a locking state. When hydraulic oil enters the hydraulic cylinder body through the oil inlet hole, the hydraulic cylinder body is enabled to be pushed against the locking nut, the hydraulic cylinder piston is pushed against the ram, and hydraulic pressure is adjusted, so that the ram does not generate relative displacement with the upright column in the stamping process.

The device comprises a frame 1, a stand column 2, a hydraulic cylinder 3, a locking nut 4, a ram 5, a cylinder body lining 6, a hydraulic cylinder piston 7, an upper end part 8, a lower end part 9, an exhaust hole 10, a screw plug 11, a sealing gasket 12, a through hole 13 and a set screw 14.
Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to more fully, accurately and deeply understand the concept and technical solution of the present invention and to facilitate its implementation.
Hydraulic pressure overload protection device, including frame 1, a plurality of stand 2, pneumatic cylinder 3, lock nut 4 and ram 5, stand 2 installs in frame 1, pneumatic cylinder 3 passes stand 2 and installs between ram 5 and lock nut 4, and the pneumatic cylinder 3 that plays overload protection passes stand 2 and installs between ram 5 and lock nut 4, and lock nut 4 is spacing by cylinder body bush 6, makes nut 2 position relatively stand invariant and can be in locking state. When hydraulic oil enters the cylinder body of the hydraulic cylinder 3 through the oil inlet hole, the cylinder body of the hydraulic cylinder 3 is enabled to be pushed against the locking nut 4, the piston 7 of the hydraulic cylinder is enabled to be pushed against the ram 5, and the hydraulic pressure is adjusted, so that the ram 5 does not generate relative displacement with the upright post 2 in the stamping process.
The quantity of the stand columns 2 is four, the stand columns 2 are respectively located at four ends of the rack 1, the structure adopts a distributed pressure overload protection mode, so that the stress of the four stand columns 2 is more uniform, and the separated hydraulic cylinder 3 is convenient to install, maintain and replace.
The hydraulic cylinder 3 comprises a cylinder body bush 6 and a hydraulic cylinder piston 7, the hydraulic cylinder piston 7 is arranged on the top of the ram 5, the cylinder body bush 6 is located between the locking nut 4 and the upright post 2, the locking nut 4 is limited by the cylinder body bush 6, and the nut is kept unchanged relative to the upright post 2 and can be in a locking state.
The diameter of the upper end part 8 of the upright post 2 is smaller than that of the lower end part 9, and the cylinder liner 6 is annularly arranged on the upper end surface of the lower end part 9 of the upright post 2.
The cylinder body top be provided with exhaust hole 10, exhaust hole 10 be furnished with plug screw 11, because the cylinder body is single-action pneumatic cylinder 3, consequently, the air in the cylinder body can not discharge when injecting hydraulic oil for the first time, so set up an exhaust hole 10 above the cylinder body, the influence of air to hydraulic pressure stability in the cylinder body is got rid of.
And a sealing gasket 12 is arranged between the screw plug 11 and the emptying hole, so that the integral sealing performance of the cylinder body is ensured.
The side of the locking nut 4 is provided with a through hole 13, the through hole 13 is provided with a set screw 14, the set screw 14 is screwed in after the locking nut 4 is locked, the nut is prevented from loosening, and when the hydraulic cylinder 3 needs to be replaced and maintained, the locking nut 4 is detached and can be taken out.
