Description
Technical field
The present invention relates to a kind of diel and forming method thereof, refer in particular to a kind of endoporus two-sided boss punching press deep-drawing shaping die and process thereof.
Background technology
current automobile making all increases its load-bearing capacity making great efforts to alleviate engine weight, two kinds of high-end belt pulley products in the automobile engine of arising at the historic moment shown in Fig. 1, Fig. 2, support former due to them is positioned at belt load and bearing centre place, therefore they have lightweight, intensity is high, large advantage of exerting oneself.Their manufacturing process is, first casting or forging material base, and then becomes belt pulley through turnery processing.Its shortcoming of this Conventional processing methods is: quality is more unstable, dynamic balancing is poor, and pore, slag inclusion, loose, metallographic structure is uneven, and production efficiency is low, and utilization rate of raw materials is low, and taking a lot of work effort expense material, processing cost is high economically.If be blank with round plate with holes shown in Fig. 3, its endoporus is allowed first to form the two-sided boss of certain thickness and height, as shown in Figure 6, again this semi-finished articles rotary pressing processing is become Fig. 1 or Fig. 2 belt pulley, manufacturing process will be made to become very succinct and easily, and product quality will inevitably rise a new step.
In order to obtain the two-sided boss of endoporus, insider is exploring always, attempt to carry out two-sided drawing by the simplest process, but only rely on common mould and simple technical process control does not reach requirement, often cause material deformation excessively (exceeding material deformation values allowable), product ruptures, and has to give up halfway.If take the method for spinning to produce the two-sided boss of endoporus with round plate with holes, also there will be a lot of adverse consequences, because can change the spinning of this shaped materials and destroy internal organizational structure and the metal streamline of the original rolling of material, thus reduce original intensity of metal greatly, even cannot carry out finite element analysis to its intensity; In fact and infeasible meanwhile, its spoke surface of belt pulley product processed as blank with this goods is extremely coarse, and very unsightly, thus this process.
Summary of the invention
The present invention will solve above-mentioned technological deficiency of the prior art, and provide a kind of technical process succinct, production efficiency is high, and utilization rate of raw materials is high, has endoporus two-sided boss punching press deep-drawing shaping die and the process thereof of wide Applied economy value.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of endoporus two-sided boss punching press deep-drawing shaping die, comprise the concave-convex mold and elastic material plate that cooperatively interact, it is characterized in that: the described concave-convex mold cooperatively interacted has the first preforming tool, second preforming tool and the 3rd mould, the punch front end contour shape of the first preforming tool is made up of the involute of two sections of different radiis, the punch front end of the second preforming tool has an annular table terrace, and the punch front end profile of the 3rd mould is made up of the involute of multistage different radii.
The endoporus place of the elastic material plate of the 3rd further described mould has groove.
Adopt with the endoporus of mold two-sided boss punching press drawing and forming process, comprise following concrete steps:
Step 1: be placed on the die of the first preforming tool by round plate blank with holes location, compress with elastic material plate, hydraulic press drives the punch of the first preforming tool descending, compressing at a slow speed, forms the first boss;
Step 2: hydraulic press is up, takes out workpiece, turn-over, and location is placed on the die of the second preforming tool;
Step 3: compress the workpiece on the second preforming tool die with elastic material plate, hydraulic press drives the punch of the second preforming tool descending, compressing at a slow speed, forms second miniature boss;
Step 4: hydraulic press is up, takes out workpiece, and location is placed on the die of the 3rd mould;
Step 5: compress the workpiece on the 3rd mould die with elastic material plate, hydraulic press drives the punch of the 3rd mould descending, compressing at a slow speed, forms the second boss;
Step 6: hydraulic press is up, will complete workpiece and take out.
Further, described process controls the descending degree of depth of hydraulic press and speed by PLC system.
Adopt the finished surface of the product produced with mold and process to have the fineness identical with material base surface, the inside metallographic of product have metal streamline continuously, the feature of dense structure, the structural strength of product increases.
