Abstract
A molding die of a bending steel plate comprises an upper die (1) and a lower die (2), an upper end (11) of the upper die (1) is connected with a press machine, the lower die is positioned rightly below the upper die (1), characterized in that, a lower end (12) of the upper die (1) is a cylinder which is arranged in the transverse direction, the diameter (Phi) of the cylinder is 198 - 202 mm, a circular arc die cavity (21) corresponding to the circular arc surface of the cylinder is provided at the top surface of the lower die (2), the circular arc radius (R) of the circular arc die cavity is 110 - 114 mm. Compared with the prior art, the utility model has advantages that 1. the length of the die is 1000 mm, the bending steel plate with the thickness of 6 - 20 mm can be pressed at one time, the production efficiency is improved, and the labor strength is reduced; 2. the manufacturing of the molding angle (the standard is 90 degrees) is good at one time, the partial difference is in the standard range to conform to the assembly requirements of an end girder and vehicle wheel box bodies; 3. during molding, the distortion phenomenon can not be generated, so that the assembling qualities of the end girder and the vehicle wheels in the nest step can be ensured, the appearance is beautiful, and the quality is reliable.
Description
Technical field
The utility model relates to a kind of Mold Making technical field, especially refers to a kind of mould of curved plates.
Background technology
Existing a kind of application number discloses a kind of structure for the Chinese invention patent that the CN200710057635.5 name is called " a kind of rotating type ship body plate bending forming mould ", its structure comprises upper die and lower die, it is characterized in that patrix comprises rotatable movable punch pressure head, counterdie comprises two rotatable fulcrums, and two rotatable fulcrums of the rotatable movable punch pressure head of patrix and counterdie constitute the mold pressing relation of isosceles triangle; Said patrix and counterdie are die sinking and matched moulds state according to outer drive unit.The superiority of this invention is: in steel plate bending, saved the working method at the artificial moving steel plate of steel plate width direction, improved production efficiency, reduced working strength of workers; Rotoflector can obtain continuous curved shape, bending quality height; The rotary moveable punch pressure head that replaceable diameter is different is fit to the requirement of crooked different curvature radius.But its shortcoming is: this mould project organization complexity, be equipped with rotatable fulcrum and movable punch pressure head as needs, and this mould is very easy to decrease part, reason is pivot point and movable pressure head easy deformation after repeatedly working, until not using, so its service life is shorter, so its structure awaits to improve.
Summary of the invention
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of simple in structure, firm, Forming Quality is good, produce to imitate the mould of the curved plates of height and long service life.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the mould of this curved plates, include upper die and lower die, the upper end of described patrix is connected with forcing press, described counterdie be positioned at patrix under, it is characterized in that: the lower end of described patrix is the cylinder of horizontally set, this cylindrical diameter is 198～202mm, described counterdie has and the corresponding circular arc die cavity of cylindrical arc surface at end face, and the arc radius of this circular arc die cavity is 110～114mm.
As improvement, the cylindrical diameter in described counterdie lower end can be preferably 200mm, and the arc radius of counterdie circular arc die cavity is 112mm.
Improve, the bottom surface of described circular arc die cavity is distributed with at interval and interconnective dividing plate again.
Compared with prior art, advantage of the present utility model is: 1, the long 1000mm of mould mould can be thickness that the disposable compacting of bent plate of 6～20mm forms, and has improved production efficiency, has reduced labour intensity; 2, the angle of moulding (standard is 90 °) is made one-time-reach-place, and deviation meets end carriage and the matching requirements of wheel casing in critical field; 3, in the process of moulding, the phenomenon that can not be distorted, for next step end carriage and wheel assembly quality provide assurance, and appearance looks elegant, reliable in quality.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
To shown in Figure 5, the mould of the curved plates of present embodiment includes patrix 1 and counterdie 2 as Fig. 1, and the upper end 11 of patrix 1 is connected with forcing press, counterdie 2 be positioned at patrix 1 under.The lower end 12 of patrix 1 is the cylinder of horizontally set, and this cylindrical diameter phi is 198～202mm, and present embodiment is preferably 200mm.End face at counterdie 2 has and the corresponding circular arc die cavity 21 of cylindrical arc surface, and the arc radius R of this circular arc die cavity 21 is 110～114mm, and the present embodiment radius R is for being preferably 112mm.Be distributed with in the bottom surface of circular arc die cavity 21 at interval and interconnective dividing plate 22, sound construction not only, and can save the making material of counterdie 2.
The operation principle of mould:
Utilize steel plate 3 good plasticity and processing technology, at normal temperatures, steel plate 3 is placed on the dip mold, by external certain pressure, press down through top die, make steel plate reach the crooked variable of regulation, be about to the disposable tooling device that is bent into angle of bend of steel plate.
The effect of mould:
Be used for electric block double girder overhead crane end carriage, wheel case making bent plate.
Mould of the present utility model is the process innovation design of carrying out on former less mold foundation, and the thickness range of pressure-bearing steel plate reaches: 6mm-20mm.It is the successful example that my company's process equipment designs and produces.
