Abstract

The invention relates to a die replacing method used in large hydraulic device die forming production, in particular to a quick die replacing method. The quick die replacing method comprises the steps of manufacturing die clamps consisting of connecting plates and bearing plates; manufacturing translation tools consisting of transportation trolleys and frame structures; unloading a die, namely hoisting two die clamps to the front and rear sides of a die respectively and then connecting the die clamps to the die through bolts; respectively pushing two translation tools to the positions of the die clamps on the front and rear sides of the die and then locking the translation tools and the die clamps through upper and lower fasteners; pushing and pulling the translation tools and pulling down the die from a working table; finishing pre-assembly of the other die clamp, the translation tools and a new die to be replaced by using a die unloading method while die unloading, and quickly pushing the new die to be replaced onto the working table after unloading the first die. The problems of long traditional die replacement time and complicated steps are solved, and the quick die replacing method has the advantages that the method is simple and convenient, the time is saved, the dies are not easily damged, and continuous production is ensured.

Description

The method of quickly replacing mould

Technical field

The present invention relates to Large Hydraulic Equipment mould molding produce in the more method of mold exchange, specifically a kind of method of quickly replacing mould.

Background technology

In using formed in mould Large Hydraulic Equipment production, unanimously there are suitable distinct issues in the die change for mould, because of die quality larger, when die change, should be noted that and can not collide production equipment and mould simultaneously, cause equipment fault or mould to damage, so die change process time is longer, complex steps, has had a strong impact on the continuous production of Large Hydraulic Equipment.

Summary of the invention

The present invention is intended to solve the problem of length, complex steps of above-mentioned die change process time, and provide a kind of simple and convenient, reduce mould replacing time, the stability that can guarantee mould in die change process simultaneously, is difficult for mold damage, guarantees the method for quantity-produced quickly replacing mould.

The technical scheme that the present invention solves described problem employing is:

A method for quickly replacing mould, carry out in the steps below:

A. make die clamp, the main body of described die clamp is comprised of connecting plate and the bearing plate that is fixed on connecting plate outside, and on connecting plate, corresponding mould lifting has through hole with bolt hole position, and connecting plate bottom is fixed with buckle, die clamp is made four, and two is a set of;

B. make translation frock, the main body of described translation frock is comprised of travelling bogie and the frame structure frame being fixed on travelling bogie, in frame structure frame, be fixed with jack, frame structure frame side be fixed with die clamp described in step a on the locked lower buckle of upper buckle, four of translation frock makings, two is a set of;

C. mould unloading: (I) is lifted into both sides before and after mould with overhead traveling crane respectively by two die clamps, then die clamp is connected on mould with bolt by the through hole on die clamp connecting plate and the hole for hoist on mould; (II) shifts two translation frocks respectively onto the die clamp place of both sides, mould front and back, then the lower buckle in translation frock is buckled in the upper buckle on die clamp, use the bearing plate on the jack jacking die clamp in translation frock, by die clamp and mould while jack-up, until upper and lower buckle is locked; (III) push-and-pull translation frock, leaves behind mould from workbench;

D. new die changes the outfit: mould unloading simultaneously, is assembled completely by other two die clamps and other two translation frocks and new die to be changed by unloading modeling method in advance, after first set mould mould unloading, fast new die to be changed is shifted onto on workbench.

Adopt the present invention of technique scheme, compared with prior art, its outstanding feature is:

Can realize the quick die change work of on-the-spot mould.Simultaneously the method to mould and frock require low, can be in workshop direct processing and fabricating, do not need to carry out loaded down with trivial details improvement and complicated job step, can effectively reduce the workload of mould die change, effectively reduce mould replacing time, save production cost.In addition, the method highly versatile, applied widely, safe coefficient is high, suitable popularization.

The specific embodiment

Below in conjunction with embodiment in detail the present invention is described in detail, object is only to understand better content of the present invention.Therefore, the cited case does not limit the scope of the invention.

The method of quickly replacing mould described in the present embodiment, carry out in the steps below:

(1) mould 1 shown in Fig. 1 is carried out to DATA REASONING.Mould 1, in when design, for the ease of lifting, is provided with bolt hole 2 for lifting in mould 1 both sides, need to measure this hole for hoist position and size, so that the manufacturing and designing of follow-up die clamp.

(2) after lifting is determined by bolt hole 2 positions and size, start to make die clamp.Referring to Fig. 2, Fig. 3, the main body of die clamp is comprised of connecting plate 3 and the bearing plate 4 being welded on connecting plate 3 outer panel faces, and the lifting on connecting plate 3 on corresponding mould 1 is offered corresponding through hole 5 with bolt hole 2 positions, and buckle 6 on fixing in connecting plate 3 bottoms.Die clamp is made four, and two is a set of, is respectively used to quick mould unloading and quick die change.

(3) make translation frock.Referring to Fig. 4, the main body of translation frock forms by travelling bogie 7 and with the frame structure frame 8 that travelling bogie 7 is welded as a whole, and the interior employing framework of frame structure frame 8 fixed form is jack 9 fixedly, to facilitate dismounting.Frame structure frame 8 sides are fixed with the upper buckle 6 on die clamp and coordinate locked lower buckle 10.Translation frock quantity is identical with die clamp quantity, makes equally four, and two is a set of being used in conjunction with.

(4) mould unloading (referring to Fig. 5, Fig. 6):

(I) aborning, the lifting of mould 1 is positioned at both sides, overall press front and back with bolt hole 2 positions.Therefore, the first step, is first lifted into respectively the both sides, front and back of mould 1 by two die clamps with overhead traveling crane, then, by the through hole 5 on the connecting plate 3 of die clamp and the bolt hole 2 for lifting on mould 1, with bolt 11, die clamp is connected on mould 1;

(II) second step, shifts two translation frocks respectively onto the die clamp place of mould 1 both sides, front and back, then the lower buckle 10 in translation frock is buckled in the upper buckle 6 on die clamp.Because upper buckle 6 gaps are greater than lower buckle 10, so now translation frock and die clamp integral body are in released state.So use the bearing plate 4 on the jack 9 jacking die clamps in translation frock, by die clamp and 1 while of mould jack-up, until upper and lower buckle is locked.

(III) the 3rd step, is used jack or additive method push-and-pull translation frock, utilizes travelling bogie 7 to take turns right rolling, and mould 1 is left behind from workbench.

(5) new die that changes the outfit: in mould unloading, other two die clamps and other two translation frocks and new die to be changed are assembled completely by unloading modeling method in advance, after first set mould mould unloading, fast new die to be changed is shifted onto on workbench.
