Abstract
The utility model discloses a large oil cylinder which comprises a cylinder barrel, a cylinder cover and a piston rod. The outer wall of the lower end of the cylinder barrel is provided with a annual groove, the annual groove is provided with an opening snap ring, the upper portion of the outside of the opening snap joint is provided with a snap ring sleeve flange, and the snap ring sleeve flange is fixed with a flange on the cylinder cover through a bolt. An inner hole of the bottom end of the snap ring sleeve flange is provided with a steeped hole which is matched with the opening snap joint. The large oil cylinder is simple in structure and practical in functions. The oil cylinder is convenient to demount and maintain, so processing is labor-saving and time-saving. The large oil cylinder improves safety performance of oil press devices and prolongs service lives of the oil press devices.
Description
Technical field
The utility model relates to a kind of mill type cylinder.
Background technique
At present, large pressing machine equipment Large-scale Reciprocating oil cylinder bottom structure form, the traditional interior clasp type of ram cylinder bottom structure form employing, cylinder body flange bolt are fixed.This kind large pressing machine equipment Large-scale Reciprocating oil cylinder bottom structure formal approach is for the processing of the cylinder body of Large-scale Reciprocating oil cylinder, install and fix (location) and bring very large difficulty.The difficulty of processing of cylinder body is large, and cylinder block end flange diameter is large, and boring cylinder and hone oil cylinder need equipment increase, machining difficulty greatly during machining.The installation difficulty of oil cylinder is large, poor safety performance.
Forging, difficulty of processing for the cylinder body of Large-scale Reciprocating oil cylinder are large, and because cylinder block end flange diameter is large, boring cylinder and hone oil cylinder need that equipment increases, the machining difficulty is large during machining.Installation poor safety performance for the Large-scale Reciprocating oil cylinder.
The model utility content
The utility model purpose is to provide a kind of mill type cylinder, and is simple in structure, and installation, maintenance is convenient at the bottom of the oil cylinder, the device security performance is good, easily processing.
To achieve these goals, the utility model adopts following technological scheme: a kind of mill type cylinder, comprise cylinder barrel, cylinder cap and piston rod, cylinder barrel lower end outer wall is provided with annular groove, annular groove is provided with the buckle snap ring, top, the slotted collar outside is provided with snap ring cover flange, is bolted between the flange on snap ring cover flange and the cylinder cap.
Snap ring cover flange lower end endoporus is provided with the step hole that cooperates with slotted collar.
The utility model is simple in structure, practical function, and oil cylinder loading and unloading and maintenance be very convenient, processing saving of work and time all, improves oil hydraulic press device security performance, has increased the working life of oil hydraulic press equipment.
