Abstract
The invention discloses a molding technology for crankshaft forged piece flanges capable of being accurately grabbed by a robot. The molding technology comprises the following steps: utilizing a CAE technology, stimulating and analyzing the shapes of pre-forged flanges and finish-forged flanges by using an FORGE software, determining the sizes of the flanges according to the shapes, designing the position of a flange positioning table, and finally molding the flanges. The technology has the advantages that the molding of the crankshaft forged piece flanges is stable, the accurate grabbing rate of the robot is high, fully-automatic forging is guaranteed, and the production profitability is substantially improved.
Description
Technical field
The present invention relates to crankshaft forging shaping, particularly in crankshaft in hot forging procedure, the forging flash setting process that robot accurately captures can be adapted to.
Background technology
In the process of crankshaft forging blank, when forging forwards trimming operation to from die forging, because forging flash is shaping irregular, cause robot material grasping inaccurate, often occur that the position of robot material grasping and overlap have collision.If once there is this situation when producing, the production line that will stop is to adjust the material grasping position of robot, and meanwhile also can cause intermediate frequency furnace and get rid of material phenomenon, other operations treat the problems such as work, cause many-sided waste unnecessary.
Summary of the invention
The object of the invention is by doing overlap shaping platform at bent axle blocking counterdie and finish-forging counterdie, by shaping to forging flash thus solving the problem that robot accurately can not capture overlap.
The technical scheme realizing the object of the invention is:
The crankshaft forging overlap setting process that robot accurately captures can be adapted to, comprise the steps:
1) design overlap positioning table: use CAE technology, analyze the shape of overlap generation with FORGE software simulation, thus determine overlap size, and then design overlap positioning table; Wherein, in order to not allow the overlap positioning table of the overlap of blocker forging and finish-forging have interference, blocking positioning table is laterally all increased 5mm than finish-forging positioning table with the size of radial direction;
2) overlap positioning table is processed: according to the overlap positioning table pattern designed, built-up welding is carried out in the overlap material grasping position of blocking counterdie and finish-forging counterdie, then go up machining center positioning table is processed, make positioning table in the place that patrix is corresponding simultaneously and dodge;
3) overlap preformed: reach the standard grade after Mould Machining is complete and forge, overlap is along with forging stock preformed on blocker;
4) overlap final shaping unit: be put into finishing on finisher by after forging stock preformed, overlap simultaneously also final shaping unit on the positioning table of finisher;
5) robot accurately captures overlap: robot accurately captures the overlap after finishing, forwards trimming operation to from die forging operation.
The advantage of present invention process is: crankshaft forging overlap stable molding, and the accurate snatch rate of robot is high, and for Full-automatic forging provides strong guarantee, productivity effect significantly improves.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of unshaped crankshaft forging overlap;
Fig. 2 is the schematic diagram of the crankshaft forging overlap after sizing.
Detailed description of the invention
Below in conjunction with drawings and Examples, content of the present invention is elaborated, but be not limitation of the invention.
Embodiment
The crankshaft forging overlap setting process that robot accurately captures can be adapted to, comprise the steps:
1) design overlap positioning table: use CAE technology, analyze the shape of overlap generation with FORGE software simulation, thus determine overlap size, and then design overlap positioning table; Wherein, in order to not allow the overlap positioning table of the overlap of blocker forging and finish-forging have interference, blocking positioning table is laterally all increased 5mm than finish-forging positioning table with the size of radial direction;
2) overlap positioning table is processed: according to the overlap positioning table pattern designed, built-up welding is carried out in the overlap material grasping position of blocking counterdie and finish-forging counterdie, then go up machining center positioning table is processed, make positioning table in the place that patrix is corresponding simultaneously and dodge;
3) overlap preformed: reach the standard grade after Mould Machining is complete and forge, overlap is along with forging stock preformed on blocker;
4) overlap final shaping unit: be put into finishing on finisher by after forging stock preformed, overlap simultaneously also final shaping unit on the positioning table of finisher;
5) robot accurately captures overlap: robot accurately captures the overlap after finishing, forwards trimming operation to from die forging operation.
See figures.1.and.2, crankshaft forging overlap is accurately captured in order to robot can be allowed, unidirectional two material grasping positions should be met and fly that paracentral distance is consistent, regular shape, namely in accompanying drawing, 1 and 2,3 and 4 places should remain on same straight line respectively, and overlap could accurately, stably be picked up by robot like this.Fig. 1 is unshaped crankshaft forging overlap, and in figure, the material grasping position of 1 and 2,3 and 4 is not all on the same line, and out-of-shape; Fig. 2 is the crankshaft forging overlap after sizing, and in figure, the material grasping position of 1 and 2,3 and 4 all on the same line, regular shape.
