Abstract
A precise forging combined body cold forging device belongs to the field of a bearing manufacturing device. Defects such as large working allowance, low efficiency, more consumed materials and low performance precision exist in the prior art. The precise forging combined body cold forging device comprises a punching machine, an upper die, a die holder and a lower die, wherein the upper die is installed on a slide block of the punching machine, the die holder is fixedly installed in a punching machine cavity right below the slide block, the upper die is provided with a punch head, the lower die is a hollow bushing with an annular projection, and the annular projection is embedded on the wall of the inner cavity of the die holder. The precise forging combined body cold forging device is small in working allowance, high in efficiency, high in performance and precision, fewer in consumed materials (more than 20 percent of consumables can be reduced), easy to machine and capable of prolonging the service life of a product.
Description
Technical field
The utility model belongs to bearing manufacturing equipment field, and is especially relevant with a kind of finish forge association forging apparatus.
Background technology
The inside and outside circle processing technology of traditional conical bearing adopts outer ring reaming inner ring extrusion forming process, and its particular content is as follows: outer ring reaming process: the type of drawing materials → heating in medium frequency → blanking → jumping-up → jacking → rise is clapped → reaming → shaping → spheroidizing → ball blast (descale) → thick (car) processing → essence (car) processing; The cold extrusion shaped step of inner ring: clap → spheroidizing → ball blast → thick (car) processing → essence (car) processing with the material core → jumping-up behind the jacking of outer ring → extrusion modling → punching.
The forge hot processing technology allowance of above-mentioned employing is large, yield poorly, feed consumption, time-consuming, difficulty of processing is large, precision performance is low, need further machining to improve the precision of product, this production model day by day is difficult to satisfy high-quality, high accuracy, high efficiency, the low consumed requirement in the industrial production such as current bearing manufacturing.For this reason, people imagine best metal forming technique, and it is exactly cold-forging technique, has following advantage: improve machining accuracy, reduce energy consumption, improve working (machining) efficiency.
Summary of the invention
The purpose of this utility model is exactly to have the defective that allowance is large, precision performance is low for above-mentioned prior art, provides that a kind of allowance is little, efficient is high, feed consumption is few, easy processing, performance and the high finish forge association forging apparatus of precision.
For this reason, the utility model is by the following technical solutions: a kind of finish forge association forging apparatus, comprise punch press, patrix, die holder and counterdie, patrix is installed on the slide block of punch press, die holder is packed in the punch press cavity that is positioned under the slide block, it is characterized in that: be provided with drift on the described patrix, described counterdie is arranged to the hollow sleeve with annular projection, and this annular projection is inlaid on the described die holder internal chamber wall.
The taper with step can be arranged in described drift top, adds man-hour when workpiece places this forging apparatus, and drift falls and with this workpiece cold-forge forming.
The finish forge association that described forging apparatus cold extrusion forms is shaped as the circular cone tower, and this finish forge association is the sub-assembly that jacket and inner sleeve combines as a whole, and inside and outside cover internal diameter need not machining.
The utility model can reach following beneficial effect: the utility model has improved the dimensional accuracy of part and good surface roughness, the precision of part can reach IT8～IT9 level, surface roughness can reach Ra0.8～Ra1.6, the part of gained only has a small amount of fine finishining that needs like this, circular cone inner-outer sleeve internal diameter all need not reprocessing, so that allowance is little, reduced the material consumption; Production efficiency of the present utility model is high, and its productivity ratio can be up to 30/more than the per minute, can be good at finishing production task; The utility model improves mechanical property and the precision of part, can ensure well the quality of part.
