A kind of horizontal pipe-expanding machine driving mechanism
The utility model relates to a kind of horizontal pipe-expanding machine driving mechanism.
Horizontal pipe-expanding machine is the common equipment of pipeline mouth of pipe processing and forming, has the advantages that efficiency is high, rhythm is fast, widely uses in processing and forming.
The move mode that the horizontal pipe-expanding machine of tradition controls flare seat advance and retreat realizes in conjunction with trapezoidal screw and hydraulic cylinder mechanism, manually rotation hand wheel drives trapezoidal screw, the flare seat that rotarily drives trapezoidal screw moves the original position regulating flare seat, then is stretched by the piston rod of hydraulic cylinder that to drive flare seat to retreat mobile.This method needs manual adjustment just can complete, and not only workload is large, efficiency is low, and needs to be equipped with special hydraulic station, and cost is higher.Moreover trapezoidal screw positioning precision is lower, for inapplicable during the operation that precision prescribed is high.
Summary of the invention
Control the weak point of flare seat type of drive for traditional pipe-expanding machine, the purpose of this utility model is to provide a kind of horizontal pipe-expanding machine driving mechanism.
For achieving the above object, the utility model comprises ball screw, servomotor and holder; The output shaft of described servomotor connects ball screw, and described holder comprises left holder and right holder, and described ball screw is through left holder and right holder, and this ball screw is threaded with left and right holder.
The beneficial effects of the utility model are as follows: ball screw has high accuracy, invertibity and high efficiency feature; Servomotor arranges the original position of flare seat by PLC and drives the translational speed of ball screw, and realize parametrization management and preserve data, do not need manual movement, workload greatly reduces, and efficiency is high; Also can be used for the product processing different length specification.
Accompanying drawing explanation
Accompanying drawing 1 is front view of the present utility model;
In figure, each label respectively: (1) ball screw, (2) servomotor, (3) left holder, (4) right holder.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing 1, the utility model comprises ball screw 1, servomotor 2 and holder; The output shaft of described servomotor 2 connects ball screw 1, and described holder comprises left holder 3 and right holder 4, and described ball screw 1 is through left holder 3 and right holder 4, and this ball screw 1 is threaded with left and right holder.
The structure of relatively traditional horizontal pipe-expanding machine, the utility model eliminates hydraulic system, has the function driving the movement of left and right flare seat advance and retreat, can realize the original position of Lookup protocol flare seat; Can also regulate the translational speed of left and right flare seat, parametrization management and preservation data, by calling the parameter of preservation, can produce the product of different size.
The above, it is only a kind of preferred embodiment of the utility model, not technical scope of the present utility model is imposed any restrictions, every embodiment is above done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the utility model technology.
