Abstract

A mandril circulation device used for pulling and extending a pressing machine relates to an auxiliary device for pulling and extending the pressing machine. The mandril cooling and lubricating of the prior art has the disadvantages of production time occupying, long period, low efficiency, short continuous service life of the mandri, uneven manual lubricant coating as well as time and labor waste. The invention comprises a carrier roller supporting device, two machine trays and a stepping mechanism. Three mandril stations are arranged outside the pressing machine and the mandril of each station is supported by the carrier roller. The mandril on the cooling and lubricating stations can rotate. Two track beams are arranged on the upward side of the mandril and the two machinery trays operate on the track beams. A lifting device provided with a gripper is arranged on the machinery tray. Four sets of vertical lifting cylinders of the stepping mechanism are connected with the tracks and a stepping beam, thus being able to lead the tracks and the stepping beam to life vertically. The stepping beam is driven by a horizontal stepping cylinder and can move horizontally along the tracks. The invention has the advantages of shortening the manufacture period, improving the working efficiency, prolonging the service life of the mandril and improving the machinery automatization of the pressing machine.

Description

The core rod cycle device that is used for drawing and extending hydraulic machine
Technical field
The present invention relates to be used to produce the auxiliary equipment of the drawing and extending hydraulic machine of bottle class part or pipe type element.
Background technology
Drawing and extending hydraulic machine mainly is the special equipment that is used for producing all size bottle class part, is to pull out in die on the plug the hot down bottle base after the punching being enclosed within, and bottle base wall thickness reduction, length are increased, and produces the steel cylinder of different wall and length.Produce used plug work under bad environment, in process of production, it is very big influenced by high temperature and frictional force, therefore after having pulled out a bottle base, need and lubricate the plug cooling.Traditional mode is for manually smearing lubricant, the cooling of artificial water spray, and a plug is reused.When the plug that more renews, because temperature is low excessively, plug need be heated, at present, heating also is a manual type.
The shortcoming that prior art exists is: 1, artificial cooling and lubricated plug have taken the production time in drawing and extending hydraulic machine, and the cycle is long, and efficient is low; 2, a plug is reused continuously, and the plug life-span shortens greatly; 3, plug can not rotate in the press, and it is inhomogeneous manually to smear lubricant, causes the bottle base metal flow inhomogeneous and take off the bottle difficulty; 4, the difficult control of temperature of artificial water spray cooling in case undercooling needs again plug is reheated, wastes time and energy.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of core rod cycle device that is used for drawing and extending hydraulic machine is provided, have the shortening production cycle, enhance productivity, prolong plug service life, improve the advantages such as mechanization, automaticity of press.
The present invention is achieved by the following technical solutions:
A kind of core rod cycle device that is used for drawing and extending hydraulic machine is made up of idler stand device, two floor trucks and stepping mechanism, is horizontally disposed with cooling station, lubricated station outside drawing and extending hydraulic machine, waits for station; The plug of each station is by idler stand, the carrying roller that wherein cools off station, lubricated station is driven by motor reducer, plug can be around self axis rotation, above plug, set up two track girders, two floor trucks move on two track girders, lifting device is housed on the dolly, under the lifting device clamp is housed; Between three plug stations stepping mechanism is set, the vertical jacking cylinder of quadruplet is connected with step rate with track, can make track and step rate vertical lift, and step rate is driven by horizontal step-by-step cylinder, and can move along track cross level.
Described two floor trucks are driven by two variable-frequency motors, and clamp and lifting beam are by Driven by Hydraulic Cylinder.Described clamp can make the clamp open and close by Driven by Hydraulic Cylinder, and the jaw of clamp is equipped with backing plate.The vertical jacking cylinder of described quadruplet is provided with lazy-tongs.Described step rate is driven by horizontal step-by-step cylinder, and its structure is: an end of step rate and two hinged connecting rods is hinged, and horizontal step-by-step cylinder is hinged on another root connecting rod.
The present invention compared with prior art has the following advantages and beneficial effect:
Because level is arranged in juxtaposition cooling station, lubricated station, waits for station outside drawing and extending hydraulic machine, horizontal stepping mechanism is adopted in circulation between three stations, the plug of cooling station can be transferred to lubricated station by stepping mechanism, the plug that will lubricate station simultaneously is transferred to the wait station; Circulate in the drawing and extending hydraulic machine and between outside the drawing and extending hydraulic machine and adopt two floor trucks transportations, a floor truck is transported to the cooling station with the plug in the drawing and extending hydraulic machine, another dolly will wait for that the plug of station is transported in the drawing and extending hydraulic machine, thereby realize the circulation of plug, with plug cooling, lubricated, simultaneously, plug can be around self axis rotation at cooling station, lubricated station in the process of circulation, the plug good cooling results, evenly lubricated.Therefore, the present invention has shortened the production cycle, has improved production efficiency, has prolonged plug service life, has improved the mechanical automation degree of press.

The present invention will be further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, a kind of core rod cycle device that is used for drawing and extending hydraulic machine is made up of idler stand device, two floor trucks and stepping mechanism, is horizontally disposed with cooling station I, lubricated station II in the outside of drawing and extending hydraulic machine Y, waits for station III; The plug 12 of each station is by carrying roller 13 supportings, the carrying roller 13 that wherein cools off station I, lubricated station II is driven by motor reducer 14, can drive plug around self axis rotation, above plug, set up two track girders 3, two floor trucks 1,2 move on two track girders 3, and lifting device 4 is housed on the dolly, and clamp 16 is housed under the lifting device, lifting device can move up and down, but the clamp open and close.
Between three plug stations, stepping mechanism is set, the vertical jacking cylinder 9 of quadruplet is connected with step rate 8 with track 11, can make track 11 and step rate 8 vertical lifts, make plug break away from carrying roller 13 and frame on two step rates 8, step rate 8 is driven by horizontal step-by-step cylinder 6, and can move horizontally along track 11, plug 12 is transferred to another station from a station.
Described two floor trucks 1,2 are driven by two variable-frequency motors 5, and clamp 16 and lifting beam 17 are by Driven by Hydraulic Cylinder.
