Abstract

The utility model relates to a wheel rim expansion mold. In the technical proposal, a lower slide plate is fixedly arranged on a lower mold plate; a plurality of lower expansion blocks arranged in the peripheral direction are arranged on the lower slide plate along a radial guide groove, and are connected through inner compression springs; a plurality of upper expansion blocks arranged in the peripheral direction are arranged to be corresponding to the lower expansion blocks in the vertical direction, connected through inner compression springs, and fixedly arranged under an upper slide plate in the axial direction; the upper part of the upper slide plate is provided with an upper mold plate; the peripheral circle of the upper mold plate is fixedly provided with an L-shaped upper connecting block; a radial arm in the lower end of the upper connecting block is arranged under the bottom surface of the upper slide plate and has a certain distance away from the bottom surface; the center of the lower surface of the upper mold plate is fixedly provided with a cone body; the inner sides of the upper expansion blocks and the lower expansion blocks are provided with conical arc-shaped surfaces with tapers corresponding to the taper of the cone body; and the profile in the butting position of the upper expansion blocks and the lower expansion blocks is a curved surface corresponding to the inner circumferential surface of a wheel rim to be processed. The utility model simplifies the mold structure, reduces the mold processing difficulty, decreases the assembly errors, improves the vertical concentricity of the wheel rim, enhances the product quality grade, and is applicable to the single product processing.

Description

Rim for automobile wheel expanding mould
Technical field:
The utility model relates to the mould in a kind of wheel production process, especially a kind of mould that is used for the typing of rim for automobile wheel expanding.
Background technology:
The expanding mould that is used for the typing of rim for automobile wheel expanding at present generally is divided into two parts up and down, and general general expanding mould mould slide block adopts the I shape guiding, and difficulty of processing is big; Adopt bicone expanding up and down, complex structure, the processing charges height, general processing producer processed mould is difficult to satisfy the demand of producing.
Summary of the invention:
The purpose of this utility model provides a kind of rim for automobile wheel expanding mould, and is simple in structure, is convenient to processing, and manufacturing expense is low, is more suitable for the production of single variety.
The purpose of this utility model realizes as follows: it relates to cope match-plate pattern, upper slide, last expanding piece, lower bolster, lower skateboard, following expanding piece and cone, lower skateboard is fixed on the lower bolster, several expanding pieces down of circumferential arrangement radially gathering sill are placed on the lower skateboard, and spring contracts in being connected with between the following expanding piece; The several last expanding piece of circumferential arrangement is corresponding with following expanding piece upper-lower position, the spring that contracts in being connected with between the last expanding piece, and last expanding piece is axially fixed in below the upper slide; Cope match-plate pattern is arranged at upper slide top, cope match-plate pattern periphery circle is gone up contiguous block on the fixed L type, connecting lever is in below the upper slide bottom surface and with the bottom surface certain distance is arranged in the last contiguous block lower end, when cope match-plate pattern moves up, last contiguous block is followed cope match-plate pattern and is moved up, behind the gap of elimination and upper slide, drive upper slide and move up, the expanding piece moves up thereby drive upward; Center fixation cone below the cope match-plate pattern, last expanding piece and following expanding piece inboard have and the corresponding awl cambered surface of cone taper; Last expanding piece and following expanding piece joint outline are and the corresponding curved surface of wheel rim inner peripheral surface to be processed.Cope match-plate pattern is contained on the upper table, and upper table is descending, and cope match-plate pattern is descending, and cone follows that it is descending, and expanding piece, expanding piece outwards motion simultaneously down reach the purpose that makes wheel rim girth and internal diameter size increase and play the expanding typing in the drive.Upper table is up, and cone is up, and last expanding piece, following expanding piece return under the effect of the interior spring that contracts also separates certain distance up and down, and wheel rim can take out.
The spring that contracts in top is connected with between the following expanding piece, the spring that contracts in the bottom is connected with between the last expanding piece, spring contracts in top is connected with between the last expanding piece.
On the expanding piece bolt is set on each, bolt top is in the radial groove of upper slide, makes expanding piece outwards expanding or inwardly contraction.
The beneficial effect that the utlity model has is: go up the expanding piece and lead with bolt, counterdie leads with gathering sill, has reduced difficulty of processing, has reduced rigging error; Adopt single cone expanding, simplified mould structure, reduced the difficulty of processing of mould, improved the axiality up and down of rim for automobile wheel.Utilize its grade of improving the quality of products, be fit to the processing of single product.
Description of drawings:
Accompanying drawing is the structural representation of the utility model rim for automobile wheel expanding mould.
The specific embodiment:
With reference to accompanying drawing, lower skateboard 7 is fixed on the lower bolster 8, and several expanding pieces 6 down of circumferential arrangement radially gathering sill are placed on the lower skateboard 7, and spring 5 contracts in top is connected with between the following expanding piece 6; The several last expanding piece 4 of circumferential arrangement is corresponding with following expanding piece 6 upper-lower positions, spring 5 contracts in bottom and top are connected with between the last expanding piece 4, last expanding piece 4 is axially fixed in below the upper slide 2, on the expanding piece 4 bolt is set on each, and bolt top is in the radial groove of upper slide 2; Cope match-plate pattern 1 is arranged at upper slide 2 tops, and cope match-plate pattern 1 periphery circle is gone up contiguous block 3 on the fixed L type, and connecting lever is in below upper slide 2 bottom surfaces and with the bottom surface certain distance is arranged in last contiguous block 3 lower ends; Center fixation cone 9 below the cope match-plate pattern 1, last expanding piece 4 and following expanding piece 6 inboards have and the corresponding awl cambered surface of cone 9 taperings; Last expanding piece 4 and following expanding piece 6 joint outlines are and the corresponding curved surface of wheel rim inner peripheral surface to be processed.
