Description
Technical field
The utility model relates to a kind of mould, particularly a kind of engineering machinery bucket bottom sheet mould.
Background technology
The bucket that engineering machinery is used is generally formed by bottom sheet and plate-side plate welding, in order to increase the intensity of bucket, generally all at bottom sheet welding polylith stiffener.And existing engineering machinery bucket bottom sheet processing method all is respectively to bottom sheet body, stiffener blanking, then adopt three core rollers respectively to bottom sheet body, stiffener contour roll forming camber plate, again the polylith stiffener is welded on the bottom sheet body respectively one by one behind the contour roll forming.The weak point that said method exists is: one. the contour roll forming error is large, and operation is many, efficient is low; Two. because existing forming parts mould also adopts the one-piece part moulding, one-piece part molding resilience coefficient is difficult to grasp, and it is large that part assembles mismatch error mutually, and operation is many, efficient is low; Three. can only process one type scraper bowl, production cost is high, and efficient is low.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of bucket bottom sheet mould is provided, and the error that above-mentioned prior art exists is large, operation is many, inefficient weak point to solve.
The technical scheme that solves the problems of the technologies described above is: a kind of bucket bottom sheet mould, comprise counterdie and patrix, described counterdie comprises lower baffle plate, is installed in the counterdie side plate of lower baffle plate both sides respectively, and described lower baffle plate is installed on the hydraulic press lower table; Described patrix comprises cope match-plate pattern, the parallel punch that is fixed on cope match-plate pattern bottom, described punch for with the match arc rod member of arc stamping surface of workpiece shape, cope match-plate pattern is installed in the bottom of hydraulic press upper table; Also be provided with between described punch and the lower baffle plate for the adjustment backing plate of adjusting the coefficient of resilience, this adjustment backing plate is fixedly mounted on the lower baffle plate.
Further technical scheme of the present utility model is: also be connected with a plurality of stiffeners between the described counterdie side plate outside and the lower baffle plate.
Gripper shoe also is installed between described punch and the cope match-plate pattern.
The described counterdie side plate outside also is equipped with the positioning component for positioning workpieces, this positioning component comprises locating piece, stiffener, fagging I and fagging II, described fagging I and fagging II are interconnected to constitute the inverted L-shaped structure, described locating piece is fixed on the fagging II, stiffener is connected between fagging I and the fagging II, and the fagging I is fixed on the counterdie side plate.
Described counterdie is equipped with feeding material component in a side, and this feeding material component comprises cradle, a plurality of conveying roller, and described a plurality of conveying rollers are arranged in parallel and rotatably are installed on the cradle by rotating shaft, and cradle is fixed on the counterdie side plate.
Described counterdie both sides also are connected with respectively and hang rod.
Because adopt said structure, the bucket bottom sheet mould of the utility model compared with prior art has following beneficial effect:
1. error is little, and precision is high:
Use before the bucket bottom sheet mould of the utility model, respectively the stiffener blanket point after the blanking is welded on the bottom sheet body blanket surface first, spelling becomes a plane bottom sheet blank, and then carrying out shaped by fluid pressure by the bottom sheet blank of this bucket bottom sheet mould after to the spot welding spelling on the hydraulic press, can make bucket bottom sheet workpiece.Therefore, adopt this utility model after, processing bucket bottom sheet need not contour roll forming, and because several parts are that disposable liquid is molded, its error is less, and the Workpiece shaping precision can be increased to 2mm by the 10mm of three core roller apparatus contour roll formings, has greatly improved the formed precision of workpiece.
2. operation is few, and efficient is high:
Because after adopting the utility model, processing bucket bottom sheet need not to adopt three core rollers respectively to bottom sheet body, stiffener contour roll forming camber plate, also need not to be welded on one by one respectively the polylith stiffener on the bottom sheet body again behind the contour roll forming, therefore, take three stiffeners as example, bucket bottom sheet moulding process behind employing the utility model is compared operation and can be reduced to 3 procedures by 8 procedures with old technology, greatly improved production efficiency.
In addition, also be provided with between the punch of the bucket bottom sheet mould of the utility model and the lower baffle plate for the adjustment backing plate of adjusting the coefficient of resilience, adjust the coefficient of resilience by different adjustment backing plates, can realize the moulding of two kinds of bucket model bottom sheets, thereby further improve production efficiency.
3. production cost is low:
Since two kinds of bucket assemblies of the utility model energy processing and forming, less investment, and low cost of manufacture can be suitable for mass production.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of the bucket bottom sheet mould of the utility model is further described.
