Embodiment 1
As shown in Figure 1, the present embodiment sintering circular-cooler bend manufacturing method, the method is realized by following methods
's：
Step 1：Bend analogue simulation simultaneously goes out figure：
Bend analogue simulation simultaneously goes out the figure stage, using the three-dimensional artificials such as admas software as tool, by circular cooler trolley vehicle
The operation of wheel is emulated, and analog simulation goes out the running orbit of ring cold machine trolley wheel, since wheel is real-time walks in bend
On, so thus track can further generate the three-dimensional curve of ring cold machine bend, then taken out on three-dimensional curve several
Point is done if exporting the coordinate value of these points and then being taken out on three-dimensional curve, exports the coordinate value of these points；These are sat again
Mark imports CAD diagram paper, generates the two-dimension projection of bend, i.e. three-view diagram usually used in manufacture.
Step 2：According to the two-dimension projection of bend modeling tool made of paper：
Based on this figure, bend mold is designed；Manufacture level pedestal 1 first, the horizontal plane with the upper surface of pedestal 1 are
Y-direction reference plane, with the back side of pedestal 1 be X to reference plane, several coordinate points are taken from two-dimensional projection's drawing, according to taken several
L-type positioning plate 2 is arranged in the coordinate of coordinate points on the pedestal 1, in the inside notch bent angle of all L-type positioning plates 2
Two sides are laid with the vertical jointing plate 4 and horizontal abutment plate 5 of bar shaped, the vertical jointing plate 4 and the formation of horizontal abutment plate 5 respectively
Limit the bend die tracks mold of the bend.
The specific size of L-shaped L-type positioning plate 2 used all is from the coordinate data of bend respective point, the L-type positioning plate
Setting height of 2 widthwise edge on pedestal be equal to bend in the position corresponding Y-direction coordinate value and horizontal abutment plate thickness it
Difference；The thickness of the vertical edges of the L-type positioning plate 2 be equal to bend in the position corresponding X to coordinate value and vertical jointing plate
Thickness difference.
By the size setting of the L-type positioning plate from the point of view of specific of attached drawing 4：Take the bottom surface that pedestal 1 is welded with L-type positioning plate 2 for Y-direction
Reference plane takes 1 back side of pedestal as X to reference plane, and 1 back side of pedestal and 2 back side of L-type positioning plate are in same plane.L-type positioning plate
For " L " type, the thickness i.e. size Ax of the vertical edges of the L-type positioning plate is after bend 6 is placed in bend die tracks,
Bend 6 and X subtract the thickness t of vertical jointing plate 4 herein, L-type positioning plate to the distance of reference plane i.e. the X of bend to coordinate
The setting height i.e. size Ay of the widthwise edge of L-type are bend 6 and Y-direction benchmark after bend 6 is placed in bend die tracks
The distance in face i.e. the X of bend subtract the thickness t of horizontal abutment plate 5 herein to coordinate.
Step 3：Bend is carried out on the mold that step 2 obtains to bend.
Round steel is integrally heated to be placed on mold after required temperature to bend according to the constraint of L-type positioning plate, by
Quickly in round steel cooling velocity, it can influence to bend effect after cooling, the more people of such embodiment requirement, which are carried out at the same time, to be bent to save
About bend the time.I.e. multiple workers will get out bending tool, such as jack along bend axis direction, in the round steel heated
After being placed on mold, ready worker quickly withstands round steel using jack successively and bends.
Such mode that bends has many advantages, such as that speed is fast, efficient.
Embodiment 2
The present embodiment sintering circular-cooler bend manufacturing method is different from embodiment 1 only in the difference with step 3.
The present embodiment sintering circular-cooler bend manufacturing method step 3 is realized by following methods：Round steel is placed on
It is heated on mold, the constraint according still further to L-type positioning plate is bent.
Specific to be heated for round steel to be placed on mold, the constraint according still further to L-type positioning plate is bent.Now will
Round steel is placed on mold, then holds burning to that need to bend section fixed point heating, when bending temperature to be achieved, by one by 2 to 3 workers
A worker uses bending tool, such as jack pair round steel to be bent, and after the completion of bending, then adds to next section of round steel
Heat repeats last time operation, until entire round steel is bent into bend.
The present embodiment sintering circular-cooler bend manufacturing method needs number of workers few, and cost is relatively low.
As shown in Figure 4, Figure 5, no matter using it is above-mentioned which kind of bend scheme, will be taken measures after bending to bending
Round steel afterwards is fixed, and is deformed after preventing it from cooling down.The stationary fixture that round steel after bending in year is fixed is preferably square
Case is that portal frame 7 and the joint of wedge block 8 are fixed.
In the various embodiments described above, in the manufacturing process of the mold, some or all of setting between the L-type positioning plate
There is stiffener plate, can especially be welded between the L-type positioning plate of the larger position setting of corresponding bend die tracks curvature
Stiffener plate 3, and the stiffener plate is fitted in the outside setting of shown vertical jointing plate.Wherein, stiffener plate size is by phase
It answers dump rail curve to determine, stiffener plate 3 is set between the L-type positioning plate of the bigger position of corresponding bend curvature, is played anti-
The only effect of L-type positioning plate 2 and fitting steel plate deformed.
In the various embodiments described above, the pedestal 1 is laid with steel plate using shaped steel as skeleton on shaped steel, it is desirable that has bigger
Rigidity, prevent from being deformed in the hot environment of manufacturing process；The L-type positioning plate is vertically welded in the upper of the pedestal
Surface, the vertical jointing plate and horizontal abutment plate are welded to connect with the L-type positioning plate；In the big position of curvature, L-type positioning
The density of setting of plate 2 accordingly increases, and size L2, L1 is that L-type positions plate spacing, and the bend curvature that size L2 locates in attached drawing is more than ruler
At very little L1, so L2<L1.
More than, only presently preferred embodiments of the present invention, but scope of protection of the present invention is not limited thereto, and it is any to be familiar with sheet
In the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in should all be covered those skilled in the art
Within protection scope of the present invention.Therefore, the scope of protection of the present invention shall be subject to the scope of protection defined by the claims.
