A forming method of a square guide rail adopts a square guide rail forming mould, wherein a left forming inclined wedge component, a right forming inclined wedge component and a flattening, shaping and riveting component are arranged on the upper mould of the square guide rail forming mould; a left lateral pressure plate component, a right lateral pressure plate component, a left forming slide block and a right forming slide block are arranged on the lower mould of the square guide rail forming mould; an inching core filling component is arranged between the left forming slide block and the right forming slide block; a cylinder component is arranged in the middle at the real part of the lower mould, and is linked with the inching core filling component; elastic reset components are arranged on two sides of the lower mould. The mould can be a one-step formed and riveted square guide rail product, and can completely meet the technical requirements; the production efficiency is more than three times that of the conventional multi-procedure mould forming method; the production cost is greatly reduced; the strenuous labor work of a production staff is reduced; stamping facilities are reduced; the inconvenience of multi-procedure revolution is avoided.
Description
Technical field
The invention belongs to metal sheet forming method, particularly a kind of square rail forming process.
Background technology
It is all generally to adopt many cover single punch-dies to complete through multiple operation that square tube is formed in punching production, and production efficiency is low, low precision, percent defective are high.High for required precision, large in batches prolate square tube is shaped, and former multiple operation one-shot finishing die is difficult to meet its requirement.
Summary of the invention
Technical problem to be solved by this invention is: a kind of square rail forming process is provided.Reach once-forming, production efficiency is high, and machining accuracy is high, can meet production demand.
Technical scheme of the present invention is:
A kind of square rail forming process, it is characterized in that: use square rail shaping dies: on this mould mo(u)ld top half, be arranged with left shaping wedge assembly (1), flatten shaping riveted assembly (5) and right shaping wedge assembly (2), left shaping wedge assembly and right shaping wedge assembly are symmetrical; On mould mo(u)ld bottom half, be arranged with left surface holding pad assembly (3), right flank holding pad assembly, left surface holding pad assembly and right flank holding pad assembly are symmetrical; Between left surface holding pad assembly and right flank holding pad assembly, be arranged with left shaping slide block (4) and right shaping slide block, left shaping slide block and right shaping slide block are symmetrical; In the middle of the left shaping slide block of mould mo(u)ld bottom half (4) and right shaping slide block, have and can fine motion fill out core assembly (6), in the middle of mould mo(u)ld bottom half rear, have cylinder assembly (7), cylinder assembly (7) and can fine motion fill out core assembly (6) and link; Each flexible reset assembly (8) in mould mo(u)ld bottom half both sides; The left and right shaping wedge assembly of described symmetry is L shaped, has protruding drum and cammed surface on L shaped lateral surface; In the middle of described pressing shaping riveted assembly (5), there is rectangle pressing strip; On described symmetrical shaping slide block, there is oblique raised line;
Forming process step:
Process 1: preorder workpiece is pushed and can fine motion be filled out in core assembly (6) from mould mo(u)ld bottom half front end inlet.
Process 2: mo(u)ld top half moves downwards and drives left shaping wedge assembly (1), flattens shaping riveted assembly (5) and right shaping wedge assembly (2), moves down promotion left surface holding pad assembly (3), right flank holding pad assembly lateral sliding is pushed down converted products material;
Process 3: mo(u)ld top half continues action downwards, and the left shaping slide block (4) that the cammed surface of left shaping wedge assembly (1) first promotes left side slides and carries out bending forming to the right;
While process 4: mo(u)ld top half continues action downwards, the right shaping slide block on the cammed surface promotion right side of right shaping wedge assembly (2) slides left and carries out bending forming;
Process 5: mo(u)ld top half continues action downwards, shaping slide block (4) outwards slips off under the effect of two-side elastic reset assembly (8), for preventing that spring reset lost efficacy, in this process, flatten shaping riveted assembly (5) the both sides wedge slide block (4) that both sides can be shaped and be pushed into tram, while guaranteeing to flatten shaping in shaping riveted assembly (5), riveted, can not produce and interfere with the both sides slide block (4) that is shaped;
Process 6: mo(u)ld top half continues action downwards, and the shaping riveted part flattening in shaping riveted assembly (5) flattens two sheet stocks and riveted completely.In this process, left surface holding pad assembly (3) is pressed in product two sides and can fine motion fills out the side of core assembly (6) tightly always under the effect of left shaping wedge assembly (1) and right shaping wedge assembly (2), thereby guarantees interior hole dimension (18.23X5.05) ± 0.05mm;
Process 7: mo(u)ld top half upwards lifts, left shaping wedge assembly (1) and right shaping wedge assembly (2) are extracted from mo(u)ld bottom half, side holding pad assembly (3) exits reset to both sides under the effect of back-moving spring, then, cylinder assembly (7) is released square rail product from can fine motion filling out core assembly (6);
Obtain square rail product.
Effect of the present invention is:
This method can once-forming and riveted square rail product.Can reach above specification requirement completely, and production efficiency is former the more than three times of multiple operation shaping dies.Greatly reduce production cost, solve the heavy work of producers, save pressing equipment, solve the complicated of multiple operation turnover.
