Description
Technical field
The present invention relates to the general device field of heat treatment.
Background technology
Normalizing, also known as normalizing, are that (Ac refers to that free ferrite is completely reformed into Ovshinsky during heating by workpiece heat to Ac3
The critical-temperature of body, be usually from 727 DEG C to 912 DEG C) or Acm (Acm is the complete austenite of hypereutectoid steel in actual heating
The critical-temperature line of change) more than 30 ~ 50 DEG C, insulation a period of time after, taken out from stove in atmosphere or water spray, spray or blow
The metal heating processing technology of air cooling.The purpose is to be that homogenizing crystal grain refinement and distribution of carbides improves hardness, improves
Processing characteristics, removes the internal stress of material, and the size of stable workpiece prevents deformation and cracking.
When the normalizing that workpiece is carried out using normalizing furnace is heat-treated, it is necessary to which carrier chain conveying workpieces, workpiece is still put
Put on carrier chain, the contact that workpiece pinpoints holding with carrier chain during whole normalizing for a long time.Carrier chain leads to
Often constituted to weave webbed guipure by carbon steel wire, the fine and closely woven poor air permeability of structure, along with the thermal conductivity of carbon steel is poor, therefore
The heat dissipation effect of workpiece and carrier chain for a long time at fixed point contact is not so good as the local good of workpiece and air contact, therefore
The crystal grain for causing workpiece normalizing to be formed is inconsistent, easily causes workpiece and finds small deformation, is unfavorable for removing answering in workpiece
Power.
The content of the invention
The invention is intended to provide a kind of normalizing furnace chain, to avoid the workpiece in conveying workpieces from being still placed on
On carrier chain.
On a kind of normalizing furnace chain in this programme, including two guide rails being parallel to each other, guide rail spaced reciprocally
The first screw rod and the second screw rod are provided with, the first screw rod is identical with the pitch and external diameter of the second screw rod, the first screw rod and the second spiral shell
Bar is parallel to each other, and the first screw rod and the second screw rod are oppositely oriented, the first screw rod two ends and the second screw rod two ends respectively company of rotation
It is connected on two guide rails, rotary electric machine is respectively connected with the first screw rod and the second screw rod.
The technical principle of this programme and have the beneficial effect that：Workpiece is placed on the point midway between two guide rails, rotates electricity
Machine drives the first screw rod and the second screw rod to rotate in same direction, and workpiece constantly will forward be transported with the rotation of the first screw rod and the second screw rod
It is dynamic.Workpiece is during motion, due to all there is screw thread, process of first screw rod in rotation on the first screw rod and the second screw rod
In driving during workpiece in rotational direction moves, the first screw rod returns one power along the first screw rod axial direction of workpiece, makes
Obtain workpiece and oblique translation occurs on the first screw rod, during oblique translation, workpiece is remained and the first screw rod is sent out
Relative displacement is given birth to, and then avoids workpiece and is contacted for a long time with the first screw rod；Similarly, workpiece is by the first screw motion to second
When on screw rod, due to the pitch and external diameter all same of the second screw rod and the first screw rod, the second screw rod will drive workpiece in the second spiral shell
The oblique translation of opposite direction occurs on bar.First screw rod and the second screw rod cause workpiece to remain at the midpoint of two guide rails
Relative displacement occurs for position and constantly undulate advance, the first screw rod and the second screw rod that workpiece is in contact with it all the time, it is to avoid
Workpiece is stood, so as to ensure that the thermal diffusivity of workpiece is good, beneficial to the stress removed in workpiece.
Further, two guide rails are respectively the first guide rail and the second guide rail, and the first guide rail interior is hollow, the first guide rail
Joint is provided with, joint is connected with the first guide rail, in addition to resistant to elevated temperatures metal tube and air pump, one end closing of metal tube is another
End opening, the blind end of metal tube is fixed on the second guide rail, and air-vent, air-vent the first guide rail of direction are provided with metal tube
Side, the air pump is connected with the first guide rail.The openend of metal tube is plugged on joint, metal tube will complete circular arc,
Air-vent towards the first screw rod and the second screw rod, open air pump can into the first guide rail pump-in pressure gas, pressed gas is through gold
Air-vent on category pipe blows to the first screw rod and the second screw rod, increases the efficiency of radiating.When or else needing increase radiating efficiency, pull out
Air pump is closed in the openend of lower metal tube.
Further, the first screw rod two ends are separately installed with first bevel gear and second bevel gear, first bevel gear and
Second bevel gear is coaxial, is engaged with first bevel gear in third hand tap gear, second bevel gear and is engaged with the 4th bevel gear, and the 3rd

Four screw rods and the 4th bevel gear are coaxial, and it is flat that the 3rd screw rod and the 4th screw rod are each perpendicular to the first guide rail and the second guide rail is surrounded
Face.Workpiece during motion, probably due to unbalance stress and be gradually pulled to the first screw rod or the second screw rod two ends with leading
Rail is contacted, and influences the normalizing effect of workpiece.Set at the first screw rod two ends intermeshing first bevel gear, second bevel gear,
Third hand tap gear, the 4th bevel gear so that they are with the first screw rod synchronous axial system when the first screw rod is rotated, and then drive the 3rd spiral shell
Bar and the 4th screw rod synchronous axial system.When workpiece motion s are to the first screw rod two ends, it will be contacted with the 3rd screw rod or the 4th screw rod,
Screw thread on 3rd screw rod or the 4th screw rod will drive workpiece to overturn, it is to avoid workpiece long-time and the 3rd screw rod or the 4th spiral shell
Bar is contacted；Or, centrifugal force will be produced when the 3rd screw rod and the rotation of the 4th screw rod, workpiece connects with the 3rd screw rod or the 4th screw rod
Moment is touched, will be pushed by centrifugal force towards the point midway between guide rail, it is to avoid when workpiece and the 3rd screw rod or long the 4th screw rod
Between contact.
Further, snap joint is provided with the openend of the metal tube.It is easy to the openend of metal tube rapidly with connecing
Head connection.
Further, first screw rod, the second screw rod, the 3rd screw rod, the 4th screw rod are made by copper alloy.Copper alloy has
There is good thermal conductivity, be conducive to the radiating of workpiece, while the hardness of copper alloy is softer relative to ferroalloy, reduce by the first spiral shell
Bar, the second screw rod, the 3rd screw rod, the 4th screw rod scratch the risk of workpiece.
Further, first screw rod, the second screw rod, the 3rd screw rod, the 4th screw flight are rectangle or trapezoidal
Screw thread.Because the first screw rod, the second screw rod, the 3rd screw rod, the 4th screw rod are required to be in normalizing furnace for a long time, high temperature will make
Obtain them to soften, use rectangle or trapezoidal screw thread can just ensure that there is screw thread enough intensity to avoid by workpiece damage；
Also ensure between workpiece and screw thread there is enough contacts area to have driven workpiece motion s simultaneously, prevent workpiece the first screw rod,
Second screw rod, the 3rd screw rod, skid on the 4th screw rod.
