Technical field
The invention belongs to hydraulic pressure installation technical field, be specifically related to a kind of protective gear of hydraulic cylinder piston rod.
Background technique
In excellent wire rod district for sawing, rod wire rod advances on roller-way, roller-way one side is fixed, opposite side is oil hydraulic cylinder, oil hydraulic cylinder Main Function is pressure bar wire rod from the side, be convenient to cutting head cutting tail, because oil hydraulic cylinder mounting point is on roller-way side, and operator are not easy to control the progressive position of bar in operation, so often occur that at work hydraulic cylinder piston rod (diameter 45mm) is hit curved fault by product, and side pressure often, the rate occurred frequently that causes fault, sudden and uncertain, the generation of fault has increased the cost of production of repairing, increased the equipment accident trouble of shutdown time, affect rhythm of production, piston rod bending causes not clamping, and elbow appears in product in sawing process, curved tail, the inconvenience that brings cleaning crop to producers.
Summary of the invention
For addressing the above problem, the invention discloses a kind of protective gear of hydraulic cylinder piston rod, can protect piston rod, improve the quality of products, save maintenance cost.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of protective gear of hydraulic cylinder piston rod; comprise the oil hydraulic cylinder on base and base; it is characterized in that: oil hydraulic cylinder both sides are provided with bush bearing; in bearing, be provided with guide rod; guide rod aligns with the front end of hydraulic cylinder piston rod; guide rod is connected protection pressing plate with the front end of hydraulic cylinder piston rod, protection pressing plate both sides (supplied materials and material returned direction) are provided with chamfering and play the guiding role.
As a modification of the present invention, above described oil hydraulic cylinder, be provided with protective housing, hydraulic cylinder piston club head is connected with protective housing bolt.
As a modification of the present invention, above described guide rod, be provided with dust-proof cover, dust-proof cover is bolted on bearing support.
As a modification of the present invention, described protection pressing plate both sides bend angle is 15-25 °.
As a modification of the present invention, described guide rod diameter is greater than hydraulic cylinder piston shank diameter.
As a modification of the present invention, the front end of described guide rod and hydraulic cylinder piston rod is flexibly connected by bolt with protection pressing plate.
As a modification of the present invention, described protection pressing plate rear side is provided with stiffening rib.
As a modification of the present invention, described bearing support is 4, is distributed on oil hydraulic cylinder both sides.
The invention has the beneficial effects as follows:
The protective gear of a kind of hydraulic cylinder piston rod of the present invention, can protect piston rod, reduces the equipment failure time, while reducing sawing, produces elbow, curved tail, improves the quality of products, and saves maintenance cost.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following embodiment and only for the present invention is described, is not used in and limits the scope of the invention.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometrical center.
As shown in the figure; the protective gear of a kind of hydraulic cylinder piston rod of the present invention; comprise the oil hydraulic cylinder 2 on base 1 and base 1; oil hydraulic cylinder 2 both sides are provided with bearing support 4, and described bush bearing 4 is 4, is distributed on oil hydraulic cylinder 2 both sides; in bearing, be provided with guide rod 6; guide rod 6 aligns with the front end of hydraulic cylinder piston rod 8, and guide rod 6 is connected protection pressing plate 7 with the front end of hydraulic cylinder piston rod 8, and protection pressing plate 7 both sides are provided with chamfering and play the guiding role.
During work, oil hydraulic cylinder advances, and hydraulic cylinder piston rod drives guide rod to advance simultaneously; when if bar product collides, first collide protection pressing plate 7, protection pressing plate 7 has chamfering can play the effect of guiding; and guide rod 6 can be offset the impulsive contact force of bar, hydraulic cylinder piston rod 8 can be protected.
Described oil hydraulic cylinder 2 is provided with protective housing 3 above, and oil hydraulic cylinder 2 heads are connected with protective housing 3 bolts 5, protective housing 3 follow piston rod together forward-reverse prevent that iron filings, dust from dropping on piston rod, affect hydraulic cylinder piston rod 8 and pass in and out; Described guide rod 6 is provided with dust-proof cover 10 above, and dust-proof cover 10 is fixed on bearing support 4 by bolt 12, and dust-proof cover 10 prevents that iron filings, dust from entering bearing support inside, affects guide rod 6 turnover.
Protection apron 7 both sides bend angle are 15-25 ° can be guarded against bar product to collide effect best, and at protection pressing plate 7 rear sides, being provided with stiffening rib 9 can increase Anti-knocking rigidity.
In order to make guide rod 6 can block bar, collide, described guide rod 6 diameters are greater than hydraulic cylinder piston rod 8 diameters, and general hydraulic cylinder piston rod 8 diameters are 45cm, and guide rod 6 diameters are advisable at 70-80cm.
