Description
Technical field
The present invention relates to construction machinery production technical field, particularly a kind of bucket shaping dies.
Background technology
Digging machine is as a kind of main engineering machinery, and its application is very wide.Bucket on digging machine is a kind of bucket-shaped container with curved surface, and it adds man-hour, normally adopts upper and lower two mould relative rectilinear to move, thus is pressed at the bottom of curved bucket by steel plate, then the framed side wallboard of the upper bucket of welding forms.This kind of processing mode, owing to being be out of shape by steel plate at the bottom of whole bucket simultaneously, thus, required operating pressure is larger.As Chinese patent (number of patent application is 201220364866.7) " bucket bottom sheet mould ", comprise counterdie and patrix, described counterdie comprises lower mould bottom plate, is arranged on the counterdie side plate of lower mould bottom plate both sides respectively, and described lower mould bottom plate is arranged on hydraulic press lower table; Described patrix comprises cope match-plate pattern, the parallel punch be fixed on bottom cope match-plate pattern, and described punch is to match the arc-shaped rod of arc stamping surface with workpiece shapes, and cope match-plate pattern is arranged on the bottom of hydraulic press upper table; Also be provided with the adjustment backing plate for adjusting the coefficient of resilience between described punch and lower mould bottom plate, this adjustment backing plate is fixedly mounted in lower mould bottom plate; It is little that this invention has error, and precision is high, and operation is few, and efficiency is high, the feature that production cost is low, can be suitable for mass production.
Summary of the invention
The object of this invention is to provide the bucket processing unit (plant) that simple, the required operating pressure of a kind of structure is less, easy to operate.
For achieving the above object, the technical solution used in the present invention is a kind of bucket shaping dies of invention, comprises fixed die 14 and dynamic model 10, also includes dynamic model oil cylinder 6 and mold base; Described mold base comprises dynamic model oil cylinder seat base plate 1, die bottom plate 4 and dynamic model revolution bearing pin base 7, the described bottom of dynamic model oil cylinder seat base plate 1 and the right part of die bottom plate 4 are connected as a single entity, and described fixed die 14 and dynamic model revolution bearing pin base 7 are arranged on left part and the middle part of die bottom plate 4 respectively; On the top of described dynamic model oil cylinder seat base plate 1, dynamic model oil cylinder tailstock 2 is also installed, the external part of described dynamic model oil cylinder 6 and tail end cut with scissors respectively be contained in dynamic model 10 side dynamic model oil cylinder axis pin base 9 and dynamic model oil cylinder tailstock 2 on; The bottom hinge of described dynamic model 10 is contained on dynamic model revolution bearing pin base 7; Described fixed die 14 and dynamic model 10 are respectively arranged with the convex curve 15 cooperatively interacted and sag vertical curve 12.
The base plate rolling bearing pin 13 of more than two is also provided with inside the sag vertical curve 12 of described dynamic model 10.
Also be provided with die bottom plate reinforcement 5 in described dynamic model oil cylinder seat base plate 1 lower inside and die bottom plate 4 right part top, this die bottom plate reinforcement 5 top and the left side are connected with the right turning round bearing pin base 7 below dynamic model oil cylinder tailstock 2 with dynamic model respectively.
Bucket shaping dies of the present invention, adopt the dynamic model of rotary motion, thus, its structure is comparatively simple.Meanwhile, in forming process, dynamic model oil cylinder pushing dynamic model and is rotated around dynamic model centre of gyration bearing pin, and on the one hand, allow bucket end steel plate be deformed into curved surface gradually by planar shaped, thus, required pressure is less; On the other hand, dynamic model oil cylinder promotes dynamic model to rotate around dynamic model centre of gyration bearing pin, increases the arm of force of dynamic model, therefore further reduce required pressure; Again on the one hand, inside the sag vertical curve of dynamic model, be also provided with many foundation plate rolling bearing pin, substantially reduce frictional force when dynamic model sag vertical curve slips over bucket end steel plate, therefore again reduce required operating pressure.In addition, during operation, only need turn round in the gap between bearing pin base by bucket end steel plate insertion fixed die and dynamic model, starting dynamic model oil cylinder can be once-forming, and therefore, its operation is very convenient.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.Explanation below adopts the mode exemplified, but protection scope of the present invention should not be limited to this.
The present embodiment is made up of fixed die 14, dynamic model 10, dynamic model oil cylinder 6 and mold base.
Mold base turns round bearing pin base 7 by dynamic model oil cylinder seat base plate 1, die bottom plate 4 and dynamic model to form, and the bottom of dynamic model oil cylinder seat base plate 1 is vertically connected with the right part of die bottom plate 4, and one-tenth is integrated; The left part of die bottom plate 4 is arranged on above with the fixed die 14 of convex curve 15; the left surface dynamic model parallel with fixed die 14 side turns round the middle part that bearing pin base 7 is arranged on die bottom plate 4, and fixed die 14 and dynamic model turn round the gap leaving steel plate 16 at the bottom of plug-in mounting bucket between bearing pin base 7.
On the top of dynamic model oil cylinder seat base plate 1, dynamic model oil cylinder tailstock 2 is also installed; between dynamic model revolution bearing pin base 7 and dynamic model oil cylinder seat base plate 1 lower inside, die bottom plate reinforcement 5 is also installed and (is arranged on die bottom plate 4 right part top and dynamic model oil cylinder seat base plate 1 lower inside.
Be provided with below dynamic model 10 with fixed die 14 above the sag vertical curve 12 that cooperatively interacts of convex curve 15, be also provided with the base plate rolling bearing pin 13 of more than two (this example is designed to 10) in the inner side of this sag vertical curve 12.In the bottom of dynamic model 10, have pin shaft hole, turn round bearing pin 11 by dynamic model and cut with scissors in the axis hole being contained in dynamic model revolution bearing pin base 7 upper left quarter; At the right middle of dynamic model 10, be also provided with dynamic model oil cylinder axis pin base 9, (axle) end that stretches out of dynamic model oil cylinder 6 is contained in the axis hole of dynamic model oil cylinder axis pin base 9 by dynamic model oil cylinder bearing pin 8 hinge; The tail end of dynamic model oil cylinder 6 is cut with scissors by dynamic model oil cylinder tailstock bearing pin 3 and is contained in the axis hole of dynamic model oil cylinder tailstock 2.
Before using, the projecting shaft of dynamic model oil cylinder 6 retraction is put in place (shown in accompanying drawing 1, being original state), then, steel plate 16 at the bottom of plane bucket is inserted fixed die 14 and dynamic model turns round in the gap between bearing pin base 7, and fix.Then, start dynamic model oil cylinder 6, allow the projecting shaft of dynamic model oil cylinder 6 promote dynamic model 10 moving mould revolution bearing pin 11 do counterclockwise slowly to rotate, next, the base plate rolling bearing pin 13 being arranged on the inner side place of the sag vertical curve 12 of dynamic model 10 promotes bucket end steel plate 16 convex curve 15 be close on fixed die 14 and is out of shape gradually, and be configured as the bucket end 16 ｀ (for shaping puts in place state, seeing shown in accompanying drawing 2) gradually; Thereafter, dynamic model oil cylinder 6 pressurize, then, the framed side wallboard of bucket is placed on the both sides of the bucket end 16 ｀, spot welding is firm, thereafter, starts dynamic model oil cylinder 6, allows the projecting shaft of dynamic model oil cylinder 6 retract to original state, take off the bucket of preliminarily forming, complete the once-forming cycle.
Bucket shaping dies of the present invention, is applicable to the formed machining of the bucket of various digging machine, also can be used for the formed machining of curved container.
