Abstract
The utility model provides a blank holder structure of a bending press tank cover press forming die. The blank holder structure of the bending press tank cover press forming die is convenient to machine and replace in structure. According to the blank holder structure of the bending press tank cover press forming die, work efficiency is improved effectively and machining cost is reduced. The blank holder structure of the bending press tank cover press forming die comprises a blank holder body, and is characterized in that the blank holder body is provided with a groove and a quenching insert is arranged in the groove in a splicing mode.
Description
Technical field
The utility model relates to a kind of shaping moudle structure of bullodozer body parts, is specially a kind of bullodozer case lid pressure-shaped mould blank holder structure.
Background technology
The characteristics of large-tonnage bullodozer cover plate are the large and complex structures of part, expect thickly also to be increased to 2.5mm by original 1.5mm, and these have all increased the moulding process difficulty.Because steel plate materials can produce very large friction and heat with die surface when drawing, return goods the quenching hardness layer on very fast so that blank holder surface softening, profile is destroyed and blank holder can't be used, and the frequent blank holder has affected operating efficiency, has strengthened the processing cost of product.
Summary of the invention
For the defects of prior art, the utility model is carried and has been encircleed a kind of new bullodozer case lid pressure-shaped mould blank holder structure, and the convenient processing of its structure and changing can the Effective Raise operating efficiency, cut down finished cost.
The technical solution of the utility model is: it comprises the blank holder body, it is characterized in that: be provided with groove on the described blank holder, the edge assembly is hardened and is inserted in the described groove.
It is further characterized in that: harden and inserted 14; The described amalgamation face of inserting that hardens draws the flow direction angle of material when drawing greater than 5.5 degree; The described upper layout moulding muscle of inserting that hardens; Described moulding muscle surrounds rectangle.
After adopting the structure of the utility model design, the blank holder of insert structure is convenient to processing and is changed, the Effective Raise operating efficiency, guarantee lower processing cost, thereby avoided blank holder employing overall structure in the prior art, in case occuring, profile damages, will integral replacing, thus lower efficiency, strengthen the shortcoming of processing cost.The flow direction that the amalgamation face of inserting that hardens draws material when drawing becomes the design at inclination angle so that draw when drawing material can moment by the mosaic of inserting of hardening, guaranteed the quality of the moulding of product, further reduced processing cost; The upper layout moulding muscle of inserting hardens, stop material too fast mobile, simultaneously make again it have certain tension force, rely on the plastic elongation of material, make the part after drawing that stable shape and enough rigidity be arranged, effectively overcome the part wrinkling, guaranteed the presentation quality of part, guarantee the qualification rate of product, further guaranteed lower processing cost.
Description of drawings
Fig. 1 is the partial sectional view of the utility model front view.
The specific embodiment
See Fig. 1, the utility model comprises blank holder body 3, have groove (not marking among the figure) on the blank holder profile, 14 of edge assemblies are hardened and are inserted 1 in the groove, harden and consider when inserting inserting slot cloth hole that wear-resistant block amalgamation seam is on drawing the impact of Material Flow, hardening arranges 4 moulding muscle 2 on the amalgamation face of inserting, and moulding muscle 2 surrounds rectangle.The 1 amalgamation face of inserting that hardens draws the flow direction angle of material when drawing greater than 5.5 degree.
The blank holder of insert structure is convenient to processing and is changed, and has avoided that blank holder adopts overall structure in the prior art, damages in case profile occurs, will integral replacing, thus lower efficiency, strengthen the shortcoming of processing cost.
The flow direction that the amalgamation face of inserting that hardens draws material when drawing becomes the design at inclination angle so that draw when drawing material can moment by the mosaic of inserting of hardening, guaranteed the quality of the moulding of product.The upper layout moulding muscle of inserting hardens, stop material too fast mobile, simultaneously make again it have certain tension force, rely on the plastic elongation of material, make the part after drawing that stable shape and enough rigidity be arranged, effectively overcome the part wrinkling, guaranteed the presentation quality of part, guaranteed the qualification rate of product.
