Description

A kind of improved die change dolly
 
Technical field
The present invention relates generally in a kind of production process of the quickly replacing mould at various large hydraulic press, relates in particular to a kind of improved die change dolly.
Background technology
At present, knownly suppress in the various products, because the shape difference of rolled-up stock at various large hydraulic press, more mold exchange that can be very frequent, die change vehicle structure complexity in the past, efficient is low, dimensional requirement limitation to mold exchange more is little, and versatility is poor, can not satisfy instructions for use.
Summary of the invention
The objective of the invention is in order to remedy the deficiency of prior art, a kind of improved die change dolly is provided, it is simple in structure, easy to process, reduce manufacturing cost greatly, while reliability height, versatility is good, can change the various sizes mould that differs greatly fast, increase work efficiency.
The present invention is achieved through the following technical solutions:
A kind of improved die change dolly, it is characterized in that: include carrier loader and mould pushing-and-pulling device, described carrier loader rolls and is installed on the die change vehicle guide, described die change vehicle guide is laid on the ground at the place ahead of large hydraulic press or rear, the both sides of described carrier loader are separately installed with the mould guider, be equipped with the roller floating guide rail on the described carrier loader, be equipped with fixed guide on the carrier loader in the described roller floating guide rail outside, cooperate on the described roller floating guide rail mould is installed, cooperate on the described fixed guide mould pushing-and-pulling device is installed, described mould pushing-and-pulling device is dragged by mould locking device and mould and shoots a retrievable arrow device and form, the mould locking device is installed on the mould pushing-and-pulling device support, and by cylinder pushing pin shaft locking mould, described mould drags to be shooted a retrievable arrow device and is made up of reductor and linear chain, drives the mould pushing-and-pulling device support and rolls on carrier loader.
Described a kind of improved die change dolly is characterized in that: described carrier loader adds by car body and common reductor that chain sprocket driving device is formed or is made up of car body and shaft type helical speed reduction gear drive unit.
Described a kind of improved die change dolly is characterized in that: the mould guider position of described carrier loader both sides is adjustable.
Its operation principle is: by the cooperation of delivery and mould pushing-and-pulling device, mould is changed, simultaneously with mould from the workbench of hydraulic press, be dragged on the carrier loader along the roller floating guide rail, what the motion by mold locking device realized during the replacing of mould in the process, mould be to move to drag to shoot a retrievable arrow device and drive by mould, by the use of adjustable mould guider, versatility is good, is applicable to the replacing of various sizes mould.
Advantage of the present invention is:
The present invention is used in the large hydraulic press quickly replacing mould, and it is simple in structure, easy to process, reduces manufacturing cost greatly, reliability height simultaneously, and versatility is good, can change the various sizes mould that differs greatly fast, increases work efficiency.
Description of drawings
Fig. 1 is the outline drawing that die change dolly of the present invention is connected with main frame.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is the carrier loader schematic cross-section.
The specific embodiment
A kind of improved die change dolly, include carrier loader 7 and mould pushing-and-pulling device 4, carrier loader 7 is formed carrier loader 7 rollings by car body that has roller 10 and shaft type helical speed reduction gear 11 drive units and is installed on the die change vehicle guide 5, die change vehicle guide 5 is laid on the ground at the place ahead of large hydraulic press or rear, be connected with main frame sill 1, the both sides of carrier loader 7 are separately installed with adjustable mould guider 6, be equipped with roller floating guide rail 8 on the carrier loader 7, be equipped with fixed guide 2 on the carrier loader 7 in roller floating guide rail 8 outsides, cooperate on the roller floating guide rail 8 mould 3 is installed, cooperate on the fixed guide 2 mould pushing-and-pulling device 4 is installed, mould pushing-and-pulling device 4 is dragged by mould locking device 12 and mould and shoots a retrievable arrow device 14 and form, mould locking device 12 is installed on the mould pushing-and-pulling device support 13, and by cylinder pushing pin shaft locking mould 3, mould drags to be shooted a retrievable arrow device 14 and is made up of reductor and linear chain, drives mould pushing-and-pulling device support 13 and rolls on carrier loader 7.
The die change dolly course of work:
When having mould to change on the hydraulic press workbench: carrier loader 7 is before the driving of reductor 11 is displaced downwardly to the hydraulic press workbench, carrier loader backstay 15 is inserted in the locating hole, make carrier loader 7 fixing, mould pushing-and-pulling device 4 stops after dragging at mould and moving forward to limit switch 9 under the driving of shooting a retrievable arrow device 14, and link to each other with the locating hole of mould 3 on the host work platform, mould and the mold locking device needs changed by mold locking device 12 are connected as a single entity.Drag at mould and to shoot a retrievable arrow under device drives, mould from the workbench of hydraulic press, is dragged on the carrier loader along roller floating guide rail 8, stop after running into push-pull device at fixed limit switch 9.Mention the backstay 15 on the carrier loader, carrier loader 7 moves back to the die change position.Mold locking device unclamps mould, lock moulds by mold locking device 12 again after replacing with the mould that needs, before carrier loader 7 moves to hydraulic press, insert backstay 15, make carrier loader 7 fixing, mould pushing-and-pulling device is with mould advancing hydraulic pressure machine worktable, and mold locking device 12 unclamps mould and returns to the fixed position, mention backstay, carrier loader 7 cars are return the die change position.
Entire work process is finished by manual operations; If in the regulator cubicle of die change dolly, PLC is installed, also can control automatically by PLC.
