Abstract
The utility model discloses a bending mould for a car U-shaped skeleton, which is provided with an upper molding plate and a lower molding plate, wherein a sliding guiding mechanism is arranged between the upper and the lower molding plates, and the lower end surface of the upper molding plate is provided with a male die, and the upper end of the male die is provided with an upper fixed plate which is fixed on the bottom surface of the upper molding plate, and the lower end surface of the upper fixed plate is provided with a correcting limit block; both sides on the upper end surface of the lower molding plate are provided with an insertion block, and the adjacent side of the left and the right insertion blocks is respectively provided with a sliding block which slides outwards along with the inclined surface, and a gap is arranged between the sliding blocks to form a die cavity, and the lower end of the lower molding plate is provided with a guiding shaft, and a rubber body which can slide from up to down is sleeved on the guiding shaft, and the rubber body is provided with a top shaft which passes through the lower molding plate, and the upper end of the top shaft pushes against a cushion. By changing the traditional bending mould, the rebound problem in the bending procedures is solved, and the production efficiency and the product quality can be improved, and the cost can be reduced.
Description
Technical field:
The utility model relates to a kind of mould, is specifically related to a kind of mould that bends that is used for automobile U type skeleton.
Background technology:
In the market, automobile all adopts the fixing mould that bends with the bend traditional scheme of mould structure of U type skeleton, though mould is convenient to maintenance, but the resilience of blank material various degrees when crooked, so after product leaves punch, die, will when bending, opposite direction produce resilience, the product of producing is the quality instability not only, and qualification rate is low, and production efficiency is also low.
The utility model content:
The utility model has been avoided the defective that occurs in the prior art, and a kind of mould that bends that is used for automobile U type skeleton is provided, and it has solved the problem that the original production process product efficiency is low, qualification rate is low, has reduced production cost, has satisfied batch production requirement.
The technical solution of the utility model is:
A kind of mould that bends that is used for automobile U type skeleton, include cope match-plate pattern, lower bolster, between described cope match-plate pattern, lower bolster sliding guide mechanism is installed, it is characterized in that: described cope match-plate pattern lower surface is fixed with punch, the punch upper end is set with the upper mounted plate that is fixed on the cope match-plate pattern bottom surface, and the upper mounted plate lower surface is fixed with the correction limited block; Described lower bolster upper surface and arranged on left and right sides is equipped with inserts, the sides adjacent that described left and right side is inserted is separately installed with the slide block that slides laterally along the inclined-plane, there is the space to constitute die cavity between the described slide block, be placed with cushion block between the described slide block, described lower bolster has spring groove corresponding to the slide block lower position, in the described spring groove spring is installed, perforate is arranged at the spring groove top, described spring upper end overhead has push rod, described push rod passes perforate contact on the spring groove below slide block, and described spring groove lower end is sealed with bottom plate; Described lower bolster lower end is fixed with the axis of guide, is set with the rubber bodies that can slide up and down on the axis of guide, and the apical axis that passes lower bolster is installed on the rubber bodies, and the apical axis upper end is resisted against described cushion block below.
The utility model changes traditional mould structure that bends, and determines the rebound value of product in the operation of bending according to calculating and engineer testing, uses the angle of moving slider in the mould that the product rebound value is revised, and makes product meet the requirement of drawing.
Punch in the utility model and movable slider are processed certain angle correction (angle is calculated and checking according to corresponding material) respectively, insert and be fixed on the lower bolster, movable slider is slidingly connected with inserting by dovetail groove, thickness according to plate is selected different movable sliders, versatility is very high, and damages the back convenient maintenance and replacement.During work, patrix is descending, gives pressure by revising limited block and inserting to product at the terminal movable slider of stroke, with the angle correction of punch and movable slider to product resilience proofread and correct, finish and have suffered the course of work.Adopt this forming die structure to improve.
The utility model has the advantages that:
The utility model with moving slider to product resilience in the process of bending revise, solved the resilience problem of product material, made product size guaranteed, reduced and done over again and survey fees usefulness, improved product percent of pass, production efficiency and product quality, reduced production costs.
Description of drawings:
Accompanying drawing 1 is product structure figure.
Accompanying drawing 2 is a structural representation of the present utility model.
The specific embodiment:
Referring to accompanying drawing, Figure 1 shows that the structure of U type skeleton 7.
A kind of mould that bends that is used for automobile U type skeleton, include cope match-plate pattern 10, lower bolster 3, cope match- plate pattern 10,3 of lower bolsters are equipped with sliding guide mechanism, cope match-plate pattern 10 lower surfaces are fixed with punch 8, punch 8 upper ends are set with the upper mounted plate that is fixed on cope match-plate pattern 10 bottom surfaces, and the upper mounted plate lower surface is fixed with revises limited block 9; Lower bolster 3 upper surface and arranged on left and right sides are equipped with inserts 4, insert 4 sides adjacent of described left and right side is separately installed with the slide block 5 that slides laterally along the inclined-plane, there is the space to constitute die cavity between the described slide block 5, be placed with cushion block 6 between the described slide block 5, described lower bolster 3 has spring groove corresponding to slide block 5 lower positions, spring 11 is installed in the described spring groove, perforate is arranged at spring 11 groove tops, described spring 11 upper end overheads have push rod 12, push rod 12 passes perforate contact on the spring groove below slide block 5, and the spring groove lower end is with bottom plate 2 sealings; Described lower bolster 3 lower ends are fixed with the axis of guide 13, are set with the rubber bodies 1 that can slide up and down on the axis of guide 13, and the apical axis 14 that passes lower bolster 3 is installed on the rubber bodies 1, and apical axis 14 upper ends are resisted against described cushion block 6 belows.
