Description

A kind of hydraulic-driven is waved the rotational moulding machine

Technical field

The utility model relates to the rotational moulding machine, is specifically related to a kind of hydraulic-driven and waves the rotational moulding machine.

Background technology

Along with environmental protection, chemical industry, printing and dyeing, medicine, brewage, the development of industry such as accumulating, market is increasing to the demand of the product that corrosion resistant, etch-proof storage tank, storage tank, transportation trough tank, chemical industry equipment etc. can obtain by rotational molding technique, and these product forward maximization directions are greatly developed.

Wobbler (rotational moulding machine) wave running, generally adopt crank-type and steel wire rope type, crank-type adopts " falling " lever principle, because crank is short, so the arm of force is short, need the very big power of output to overcome drag torque, particularly for massive rotationally moulded machine, need multistage and heavy reducing gear, therefore the housing construction difficult design, has limited the scope of application (particularly using) of crank-type on large-scale rotational moulding machine, the steel wire rope type structure is numerous and diverse, rope woolding, puts rope, accident-proneness such as spacing.

Summary of the invention

The purpose of this utility model provides the hydraulic pressure wobbler, and it is too complicated to solve existing wobbler swing system, dangerous, and problem such as range of application is narrow.

The utility model discloses a kind of hydraulic-driven and waves the rotational moulding machine, comprise: bearing, Swing Arm, Swing Arm bearing, Swing Arm connects the Swing Arm bearing, the Swing Arm bearing fixing is on bearing, also comprise: right support abutment (bearing), right telescopic arm, right hydraulic cylinder, right hydraulic cylinder supporting bearing, right support abutment (bearing) is fixed on the right part of Swing Arm, right support abutment (bearing) is hinged with an end of right telescopic arm, the other end of right telescopic arm is connected with right hydraulic cylinder, and right hydraulic cylinder is hinged by right hydraulic cylinder supporting bearing and support; Also comprise: left support abutment (bearing), left telescopic arm, left hydraulic cylinder, left hydraulic cylinder supporting bearing, left support abutment (bearing) is fixed on the left part of Swing Arm, left support abutment (bearing) is hinged with an end of left telescopic arm, the other end of left side telescopic arm is connected with left hydraulic cylinder, and left hydraulic cylinder is hinged by left hydraulic cylinder supporting bearing and support.

Right hydraulic cylinder supporting bearing and left hydraulic cylinder supporting bearing are shared.

The beneficial effects of the utility model: the utility model uses hydraulic-driven to provide swinging driving as the rotational moulding machine, and rational in infrastructure simple, safe and reliable to operation, range of application is wider.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structural representation that the described a kind of hydraulic pressure of the utility model embodiment waves the rotational moulding machine;

Among the figure:

1, right hydraulic cylinder; 2, right telescopic arm; 3, right support abutment (bearing); 4, right hydraulic cylinder supporting bearing; 5, left hydraulic cylinder supporting bearing; 6, Swing Arm bearing; 7, Swing Arm; 8, left hydraulic cylinder; 9, left telescopic arm; 10, left support abutment (bearing); 11, support.

The specific embodiment

Referring to Fig. 1, the utility model is further described.

Embodiment 1

Present embodiment proposes a kind of hydraulic pressure and waves the rotational moulding machine, connects Swing Arm bearing 6 in the middle of the Swing Arm 7, and Swing Arm bearing 6 is fixed on the support 11, and Swing Arm 7 can rotate around the center of Swing Arm bearing 6 and wave.

Right support abutment (bearing) 3 is fixed on Swing Arm 7 right parts, and right support abutment (bearing) 3 is hinged with right telescopic arm 2 one ends, and right telescopic arm 2 other ends connect right hydraulic cylinder 1, and right hydraulic cylinder 1 is hinged by right hydraulic cylinder supporting bearing 4 and support 11.

Left support abutment (bearing) 10 is fixed on Swing Arm 7 left parts, and left support abutment (bearing) 10 is hinged with left telescopic arm 9 one ends, and left telescopic arm 9 other ends connect left hydraulic cylinder 8, and left hydraulic cylinder 8 is hinged by left hydraulic cylinder supporting bearing 5 and support 11.

Right hydraulic cylinder 1 promotes right telescopic arm 2 under hydraulic action, right telescopic arm 2 elongations by right support abutment (bearing) 3, promote upwards (left part is downward) rotation of right part of Swing Arm 7; Left hydraulic cylinder 8 promotes left telescopic arm 9 under hydraulic action, left telescopic arm 9 elongations by left support abutment (bearing) 10, promote upwards (right part is downward) rotation of left part of Swing Arm 7, and promptly Swing Arm 7 is finished once complete rocking action.The flexible mutual cooperation of left and right sides hydraulic cylinder telescopic arm.

More than be a kind of among the utility model embodiment, as extension, there is various embodiment in the utility model, for example, and 1, under a stable condition, also might adopt single cylinder to drive; 2, hydraulic cylinder maintains static, and the two-way play of the telescopic arm in the hydraulic cylinder (also claiming piston) drives; 3, piston maintains static in the hydraulic cylinder, and the two-way play of hydraulic cylinder drives; 4, adopt identical principle, can be provided with one group or organize Swing Arm 7 more, each group Swing Arm 7 all is provided with and promotes its linkage that teeters, and one group of Swing Arm 7 also can promote its linkage that teeters by one group or many groups and form.

In addition, about other parts of rotational moulding machine, as the prior art of maturation, the utility model repeats no more.
