A kind of heavy-duty coal mining machine towing tank body processing technology as described above, further illustrates and is, the casting step it
Afterwards, sand removal step is additionally provided with before annealing steps, molding sand remaining in casing is drawn with cleaning.
A kind of heavy-duty coal mining machine towing tank body processing technology as described above, further illustrates and is, in the annealing steps,
Using spheroidizing, 760 DEG C of heating-up temperature, 300 minutes are incubated, are as cold as 720 DEG C soon and are incubated 300 minutes, be cooled to 650 DEG C and go out
Stove.
A kind of heavy-duty coal mining machine towing tank body processing technology as described above, further illustrates and is, in the normalising step,
Heating-up temperature is 750~800 DEG C, is incubated 1~1.5h, air cooling of being come out of the stove after insulation.
The beneficial effects of the invention are as follows：Traction casing Stability Analysis of Structures that this technique produces, it is unlikely to deform, can effectively disappears
Except internal stress, while the technological operation is simple, with short production cycle, improves processing efficiency, and casing single piece is drawn by casting,
It can be improved casing overall performance, so as to when in use, add the intensity of traction casing.
Brief description of the drawings
Fig. 1 is overall flow figure of the present invention
Embodiment
The specific embodiment of the invention is further elaborated below.
As shown in figure 1, a kind of heavy-duty coal mining machine towing tank body processing technology provided by the invention, leads for heavy-duty coal mining machine
Draw casing processing and manufacturing, the technique comprises the following steps：Cast, anneal, rough milling, heavy boring, normalizing, heat aging processing, finish-milling and
Right boring, the technique process is few, simple to operate, the traction casing Stability Analysis of Structures that is produced by the technique, is unlikely to deform, below it is right
Each step elaborates：
(1) cast：Go out to draw tank body blank single piece by sand casting；Modeling Material used in sand casting is inexpensive easily
, Casting mold manufacturing is easy, is adapted to drawing the single-piece production of box casting, producing by batch and largely produce, and be stripped
Afterwards, it is few to draw casing casting cleaning workload.Casing single piece is drawn by casting simultaneously, can be carried casing overall performance
Height, so as to when in use, add the intensity of traction casing, avoid component breakage caused by welding or splicing.
(2) anneal：Traction tank body blank after casting is made annealing treatment；Can be to the traction after casting by annealing
Tank body blank single piece softens, and improves plasticity and toughness, homogenizes chemical composition, while remove residual stress；Preferably,
The annealing uses spheroidizing, 760 DEG C of heating-up temperature, is incubated 300 minutes, is as cold as 720 DEG C soon and is incubated 300 minutes, cooling
Come out of the stove to 650 DEG C, the traction unitarily formed intensity of tank body blank can be reduced by spheroidizing, so as to convenient processing below.
Before annealing steps, after casting step, sand removal step can also be set, the sand removal step is led for cleaning
Draw molding sand remaining in casing, improve the rate of recovery of molding sand, so as to improve the utilization rate of resource, while do not influence later step
Operation processing.
(3) rough mill：Each face of box shape is rough milled, the equal 4~5mm of made allowance in each face of profile；Add according to what is portrayed
Work line, box shape is first rough milled, the equal 4~5mm of made allowance in each face of profile, is then rough milling each correlation in the positions such as step surface, square hole
Machined surface, each equal 4~5mm of made allowance in face.
(4) heavy boring：Each row hole of heavy boring, each hole face is unilateral and the equal 4~5mm of made allowance of step surface；According to the processing portrayed
Line, each row hole of centering center, each row hole of heavy boring, each hole face is unilateral and the equal 4~5mm of made allowance of step surface.
(5) normalizing：Normalized treatment is carried out to casing；Be by normalized treatment in order to improve forging tissue, reduce hardness with
Improve machinability, heat treatment is prepared.Preferably, in the normalizing procedure, heating-up temperature is 750~800 DEG C, is protected
1~1.5h of temperature, air cooling of being come out of the stove after insulation.
