Description
Technical field
The present invention relates to it is a kind of include the cold-forge forming device with mold of the shape object space to conversion function, in more detail
It says, is related to a kind of the shape object placed with horizontal direction being enabled to shorten work flow with vertical direction setting rapidly and increase
Mass production efficiency, including with mold from shape object space to conversion function cold-forge forming device.
Background technique
In general, forging, which refers to by beaing or applying stressed mechanical means with hammer etc., makes solid metal material
The operation of certain shapes is formed, the temperature with material recrystallization is boundary, and forging temperature is referred to as more than the temperature to be hot-forged, again
Referred to as warm forging is forged under crystallization temperature, forging temperature is referred to as cold forging lower than the temperature.
Wherein, cold-forging technique is suitable for various industrial machineries because of productivity height, is especially indispensable to automobile industry
Important process.Cold forging forms fibr tissue due to generating metal flow (Metal Flow) along the outline shape of forged article
(Fibrous Structure), therefore intensity is high, durability is high, material loss is few.Most of situation is the 10% of material weight
Hereinafter, therefore production cost is lower compared to for product.And, which is characterized in that it is given birth to because by stamping press mass production
Yield is high, being capable of the high product of volume production precision.Therefore, equipment of most of techniques using molding machine (Former) is called.
But using the shape object manufacture craft of cold-forge forming device above-mentioned, existing technology in order to shape object side
By the way of directly carrying out direction conversion by handwork by operator and after progress integrated artistic in addition to conversion
The mode of progress, therefore the long period is consumed in work flow.Also, production effect is influenced because process speed is slow
Rate.
