Abstract
The utility model relates to a molding mould for a hook assembly of an automobile muffler, which is characterized by comprising an upper model block (1), a lower model block (2), an elastic device (3), a roller (4) and a shaping block (5); the lower model block (2) and the elastic device (3) below the lower model block (2) are combined into a movable mechanism which can upwards and downwards slide, two copying slots for placing bending parts are respectively arranged on the upper model block (1) and the lower model block (2), a slot which is in the shape corresponding to that of the surface of each bending part is drilled on the roller (4), the roller (4) is installed at one side which is abutted against the upper model block and the lower model block, and the shaping block (5) is positioned below the roller (4). In the utility model, not only the problems of extrusion deformation, crushing injuries, dimension tolerance, unstableness of production, low service life of the mould and the like in mould bending are solved, but also multiple assemblies can share the mould and be bent, shaped and integrally molded, and thereby the human and material resources are greatly saved, the productive labor environment is optimized, the production quality and efficiency are improved, the quality of semi-finished products is ensured, and the deformation problem in a subsequent welding process is also improved.
Description
Technical field
The utility model belongs to metallic elastic brake forming technical field.
Background technology
Along with the deep development of automatic technology, although CNC tube bending machine the applying of each neck, versatility often is difficult to be fit to different various products; From cost, practicality and benefit, mainly still manufacture at present with the research and development mould.And traditional mould bending molding process adopts centering block bending, slide block bending or the hard moulding of imitative type, have that crimp takes place material, outer surface weighs wounded or scratch in BENDING PROCESS, because of owing to manage existing pictures such as an angle that causes second order buckling and dimensional discrepancy, directly caused scrapping of product.According to the generally reaction that industry is made in the internal vapor preparation, in the manufacturing of automotive muffler hanging hook assembly, the bending forming of hook is extremely serious with the distortion of seam weldering, and distortion is unstable, makes the size of product and weldquality be difficult to reach requirement.Cause the reason of hanging hook assembly welding gross distortion: one, the space three-dimensional twist and warping are difficult points of mould bending, the position error of second order buckling and space three-dimensional angle torsional deflection directly affect the quality of semi-finished product (product before the welding), and then have caused the unstability distortion of welding.Two, residual internal stress is broken out under the high temperature when welding during elastic bending, so that the torsional deformation of product.
Summary of the invention
The purpose of this utility model is the phenomenon of three-dimensional dimension deviation, product surface damage and the bool welding deformation of the second order buckling of solution mould bending, and has realized many common modes of mould bending, reaches the production of automatic integratedization of high quality and high efficiency.
The utility model is made up of last model block [1], drag piece [2], elastic device [3], roller [4] and dressing stick [5].The elastic device [3] of drag piece [2] below it is combined into the movable device that can slide up and down, on last model block [1] and drag piece [2], all be provided with the imitative type groove of placing curved part, have on the roller [4] and the corresponding groove of curved part surface configuration, roller [4] is installed near upper and lower model block one side, and dressing stick [5] is in the below of roller [4].
Working process of mould is: will bend part with drag piece [2] matched moulds earlier and be clamped in wherein when last model block [1] is descending; Under the descending active force of last model block [1] curved part continue descending, descending in curved part want the part of bending to contact with roller [4], under the active force of roller [4], make and bend the part bending; When upper and lower mould is gone to lower-limit point, under the active force of dressing stick 5, curved part is carried out shaping.
The utility model is applicable to the bending of the workpiece of all kinds of each angle, and is big or less than the workpiece of 90 degree to bending, can repair constant slope or regulate roller and realize to the distance of type piece on the drag piece.
The utility model not only solved the mould bending crimp, weigh wounded, dimension overproof, production instability, die life are low etc. problem, and can many common modes, bent reshaping is integrally formed, saved human and material resources greatly, optimize the productive labor environment, improving the quality of production, efficient, guaranteed half-finished quality, also is the problem on deformation of improving in the follow-up welding procedure.
Description of drawings
Fig. 1 is the utility model mould structure schematic diagram, the state when going to lower-limit point for upper and lower mould, and wherein 1 is that last model block, 2 is that drag piece, 3 is that elastic device, 4 is that roller, 5 is that dressing stick, 6 is the counterdie overcoat.
Fig. 2 is the perspective view of the utility model above-below direction.Wherein 2 is that drag piece, 4 is that roller, 6 is that counterdie overcoat, 7 is workpiece.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the described mould of present embodiment adopts the mould structure of going up model block 1, drag piece 2, elastic device 3, roller 4, dressing stick 5.Drag piece 2 is combined into the movable device that can slide up and down with elastic device 3, and 6 combinations of counterdie overcoat are the each several part of counterdie fixedly.When crooked, curved part is placed on the drag piece 2 of imitative type groove, goes up model block 1 and will bend part with drag piece 2 matched moulds and be clamped in wherein when patrix is descending; The drag piece clips curved part jointly and continues descending simultaneously under the descending active force of patrix, curved part is wanted the part and roller 4 contacts (having on the roller and the corresponding groove of curved part surface configuration) of bending in descending, make curved part bending (between because of curved part and roller is rolling friction, thereby has guaranteed the surface quality of curved part) under the active force of roller; When upper and lower mould is gone to lower-limit point, under the active force of dressing stick 5, curved part is carried out shaping; The effect of dressing stick 5 can also prevent to cause the drag piece that stuck phenomenon takes place in backhaul because of downslide excess of stroke bool and roller disengaging generation resilience.
The utility model is that earlier upper and lower mould type piece matched moulds carries out bending again, and before the work, the drag piece is positioned on the roller trunnion axis, the clamping force of matched moulds can according to workpiece institute must the elastic device of bending power selection sufficient intensity, as rubber or cylinder.
Below the workpiece of various material is carried out the concrete data of warpage for the utility model:
Illustrate: percentage elongation, if bar is meant the percentage that extends diameter; If plate then is meant the percentage that material is thick.
