The manufacture of calculation machine auxiliary) for system to programming of CNC machine, the geometry of part is automatically switched to CAM system from CAD system,
Mechanic selects various processing methods on virtual display screen.After mechanic selectes certain processing method, CAD/CAM
System can export CNC code automatically, and code is input in the controller of numerically-controlled machine tool to carry out actual process operation.
In part manufactures industry, part generally requires to carry out to improve rigidity, hardness, ductility or toughness etc.
Heat treatment, for example be heated at high temperature, refining of quenching, forge, and part is having to pass through temper after Overheating Treatment so that part
Proper temperature is being returned to again after quenching, to generate corresponding metallographic attribute change.Wherein, the tempering in drawing process
The uniformity of temperature determines the tempering adequacy of part, if part tempering is insufficient, part just will produce stress cracking.
In the prior art, it is tempered efficiency to improve, part is often that high-volume concentrates tempering, a large amount of parts to be deposited in tempering frame, hold
Easily causing the bottom that heat is largely accumulated in tempering frame so that the Part temperature for being located at bottom is higher, and positioned at the part on surface layer
Temperature is relatively low, in this way, the part with batch is susceptible to the irregular situation of tempering quality, qualification rate is relatively low.
Therefore, the temper uniformity to same batch part how is improved, ensures that each part is fully tempered, improves zero
Part quality and qualification rate are those skilled in the art's technical problems urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of tempering ventilation tube, can improve equal to the temper of same batch part
Even property ensures that each part is fully tempered, and improves part quality and qualification rate.
In order to solve the above technical problems, the utility model provides a kind of tempering ventilation tube, including it is used to accommodate and several waits locating
The cylinder of part is managed, several through-holes are circumferentially evenly arranged on the surface of the cylinder.
Preferably, further include be connected with the end of the cylinder, the rotating mechanism for driving the cylinder to rotate in a circumferential direction.
Preferably, the internal diameter of the cylinder is 145~155mm.
Preferably, a diameter of 7.8~8.2mm of each through-hole.
Preferably, the spacing of the two neighboring through-hole in the axial direction is 28~32mm.
Preferably, each through-hole is circumferentially uniformly placed with 6~10 row on the surface of the cylinder.
Tempering ventilation tube provided by the utility model includes mainly cylinder, which is mainly used for accommodating each
Pending part, in the surface upper edge of cylinder, its circumferential direction is evenly arranged with several through-holes, and each through-hole can be used to make
Thermal current circulation is inside and outside cylinder.It, can will be each in this way, when a number of part to same batch carries out temper
A part is spread on drum surface, due to circumferentially offering through-hole on the surface of cylinder, is carrying out being tempered hot place
When reason, thermal current can enter inner barrel by each through-hole on drum surface simultaneously, while to each in cylinder
Part is heated, and ensures the temperature uniformity of each position in cylinder, to improve to each part in cylinder
It is tempered uniformity, and then ensures that each part is fully tempered, improves part quality and qualification rate.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
