Problems solved by technology

[0003] The object of the present invention is to provide a hydraulic cylinder for discharging with a short drive and return cycle and a moderate speed for the piston rod to extend out of the cylinder barrel, so as to solve the problem that the hydraulic cylinder for discharging in the prior art is often caused by the speed of the piston rod. Technical problems that are too fast and cause damage to the finished product

Embodiment 1

[0018] refer to figure 1 , a hydraulic cylinder for discharging, including a cylinder 1, a piston rod and an end cover 2, wherein the piston rod is slidably connected in the cylinder 1, and the end cover 2 is screwed on the cylinder 1, and the piston The rods include a first piston rod 3 towards the front end of the end cover 2 and a second piston rod 4 towards the bottom of the cylinder 1, the first piston rod 3 and the second piston rod 4 are both slidably connected in the cylinder 1 , the piston of the first piston rod 3 and the piston of the second piston rod 4 divide the cylinder 1 into a first chamber 5, a second chamber 6 and a third chamber 7, wherein the cylinder 1 is in the second chamber There are oil inlet and outlet ports at the positions of chamber 6 and third chamber 7, which are the first oil inlet and outlet port 8 and the second oil inlet and outlet port 9 respectively. There is a cavity inside the end cover 2, and the cavity accommodates an annular speed-lim...

Embodiment 2

[0021] refer to figure 2 , the difference between this embodiment and Embodiment 1 is that: the end cover 2 is provided with a slider 10 slidably connected in the end cover 2, the slider 10 is transitionally fitted with the first piston rod 3, and the first piston rod 3 Sliding can drive the sliding of the slider 10 .

[0022]When the first piston rod 3 slides towards the front end of the end cover 2, the first piston rod 3 drives the slider 10 to slide towards the front end of the end cover 2, and the slider 10 sliding towards the front end of the end cover 2 can squeeze the ring Speed-limiting airbag 11, when the first piston rod 3 has been in contact with the annular speed-limiting airbag 11 and does not pass through the annular speed-limiting airbag 11, the annular speed-limiting airbag 11 is squeezed by the slider 10 and the first piston rod 3 simultaneously. At this time, the annular speed-limiting airbag 11 can only expand toward the middle cavity of the annular speed...

Abstract

The invention belongs to the technical field of hydraulic equipment, and specifically discloses a hydraulic oil cylinder for discharge. The hydraulic oil cylinder for discharge comprises a cylinder barrel, a piston rod element and an end cover, wherein an oil inlet-outlet port is formed in the sidewall of the cylinder barrel; the piston rod element comprises a first piston rod element and a secondpiston rod element; the cylinder barrel is partitioned into a first chamber, a second chamber and a third chamber by the piston of the first piston rod element and the piston of the second piston rodelement; a cavity is formed in the end cover; an annular speed-limiting air bag is accommodated in the cavity; the inner diameter of the cavity is continuously increased in the direction where the first piston rod element stretches out of the cylinder barrel; a buffer seat is arranged at the bottom of the cylinder barrel; the piston rod of the second piston rod element can be slidably connected into the buffer seat; and a pipeline communicating the buffer seat with the second chamber is arranged on the cylinder barrel. With the adoption of the technical scheme of the invention, the technicaldefect that a finished product is usually damaged due to too high drive speed of a piston rod of a hydraulic oil cylinder for discharge in the prior art is overcome, and then the hydraulic oil cylinder for discharge is provided and is short in drive and return period and free from damage to the finished product.

Description

technical field [0001] The invention belongs to the technical field of hydraulic equipment, and specifically discloses a hydraulic oil cylinder for discharging materials. Background technique [0002] In industrial production, after the material production and processing is completed, it is often necessary to install a hydraulic discharge device at the radial position of the conveyor belt. The hydraulic discharge device pushes the finished product from the conveyor belt to achieve the purpose of finished product discharge. At this time, the driving force given by the hydraulic discharge device to the finished product should not be too large, especially when the finished product is a fragile product such as glass. However, the contradictory problem is that the reduction of the driving speed will cause the driving and return cycle of the hydraulic cylinder to be prolonged, which cannot well meet the production requirements of the process. Contents of the invention [0003] ...
