Description
Technical field
The present invention relates to forging processing technique field, specially a kind of forging line descales equipment.
Background technology
Auto parts and components such as gears or other machinery structural elements many at present, in order to ensure the machinery for having enough
Performance all produces blank using the processing method of hot forging, and it is primary and then primary that this hot forging process is generally divided into raw material heating
It an one fiery forging process of forging molding and the cooling method using ball blast is carried out to the product after one forging of a fire but removes forging table
Two fiery two forging process for carrying out finish forge are heated after the oxygen skin of face again, whether a kind of that technique is required for first in forging by steel
Raw material, which are heated to above 1000 degree of temperature, could carry out base and subsequent forging molding, and steel are being heated to 1000 degree
It is easy to generate one layer of oxide skin in material surface after above, it is necessary to which base or forging molding could be carried out by being purged, otherwise
The oxide skin on surface layer will be pressed into matrix in subsequent processing and forming, cause product rejection；Current this descaling
Number big absolutely or the mode manually cleared up with wire brush, it is time-consuming and laborious, it also clears up unclean；Also have using mechanical cleaning
, but that there is also labor intensities is big, working environment is severe, and oxide skin cleaning is not clean and injures material surface and leads
The defect of product rejection is caused, especially similar to the forging of gear class, the precision in order to improve forging needs to use two fire two mostly
The technique of forging, surface scale, which removes, when main cause is exactly One-time forging does not need totally to carry out the forging stock after One-time forging
Surface de-oxidation skin and repairing defect reheat the fiery finish forges of progress two again, and energy consumption is big, wastes greatly, and the production cycle is long, of high cost.
Invention content
It descales equipment the purpose of the present invention is to provide a kind of forging line, there is fully automatic working, oxide skin
The advantages of removing is clean, equipment performance stabilization, long lifespan；After this equipment especially is set in swage line, behaviour is on the one hand alleviated
Make the labor intensity of worker, on the other hand existing two fiery two forging process can be optimized for fiery two forging process, greatly saved
The production cycle has been saved, production cost is considerably reduced, has solved the problems of the prior art.
To achieve the above object, the present invention provides the following technical solutions：A kind of forging line descales equipment, including
Pedestal 1, electric-control system 8, the pedestal 1 are equipped with transmission device 4, sump 3 and supporting rack 6, and the transmission device 4 includes defeated
Chain 402 and the bearing material stick 401 on the conveyor chain 402, the conveyor chain 402 is sent to be led to by speed regulating motor 403
The drive of chain 404 is crossed, the filter septum 301 equipped at least three passages after descaling to being mixed with oxidation in the sump 3
The mixed water body of skin impurity carries out preliminary sedimentation filtering, avoids coarse oxide skin from entering subsequent device, prevents from damaging other zero
Component or obstruction pipeline；High-pressure injection room 5 is had on the transmission device 4, and several sprays are provided in the high-pressure injection room 5
First 501, the nozzle 501 sprays water pressure not less than 30mpa, and the conveyor chain 402 passes through the height with the bearing material stick 401
Jet chamber 5, forging raw material or blank after heating is pressed to be placed on bearing material stick 401, with conveying under the driving of speed regulating motor 403
Chain 402 enters and with certain speed by high-pressure injection room 5, makes the nozzle 501 being arranged in high-pressure injection room 5 to forging original
Material or blank surface are clean to remove the oxide skin of forging raw material or blank surface with scan mode injection high pressure water,
On the one hand super-pressure irrigation pressure not less than 30mpa keeps flow residence time on high temperature raw material or blank short, reduce high
The heat loss degree of warm raw material or blank, it is ensured that the temperature stable and uniform of high temperature raw material or blank, on the other hand high spray
Water pressure keeps the impact capacity of water jet stronger, and oxide skin is directly quickly destroyed to stripping from matrix, descaling
Effect is more preferable, and speed is faster；
