Specific embodiment
As shown in Figure 1, flat cylinder bottom is upper and lower and mould mode in the past.Mold is divided into upper mold 1 and lower die 2, need to process dovetail,
Guiding, flash gutters etc..And flash, along the entire die joint B of upper mold 1 and lower die 2, waste of material is big.
As shown in Figure 2-5, the flat cylinder bottom forging mold of the coal mine hydraulic supporting jack of the utility model, including setting levorotation
The left mould 4 of chamber and the right mould 5 that right type chamber is set, levorotation chamber and right type chamber formed shape type chamber 6 corresponding with flat cylinder bottom, type chamber 6
One end of corresponding flat cylinder bottom large end face is forging open end.It is arranged outside left mould 4 and right mould 5 and positions and clamp determining for left mould and right mould
Position clamp system.Flash only just has in forging open end, saves material.Moreover, open die forging forging can be used in the utility model
Hammer production, is no longer rely on die hammer.Mold design is simple, it is no longer necessary to process dovetail, guiding, flash gutters etc..
The outer surface of left mould 4 and the molding composition of right mould 5 is cone, and sleeve mold 3, sleeve mold is arranged outside Zuo Mo 4 and right mould 5
The conical corresponding matching that setting is formed with left mould 4 and 5 outer surface of right mould in 3 is to positioning and clamps determining for left mould 4 and right mould 5
Position chamber.Positioning chamber is open at one end or both ends open.Left mould 4 and right mould 5 are positioned and are clamped by sleeve mold 3.Forging molding process
In, using cone taper, make left mould 4 and right mould 5 it is close, guarantee molding.The utility model mold has interchangeability, only leads to
It crosses and replaces left mould 4 and right mould 5 and can meet the use of different size cylinder bottom, a sleeve mold 3 can meet a variety of cylinder bottoms simultaneously
Molding forging, saved die cost.
One end diameter that the pyramid type outer surface of left mould 4 and the molding composition of right mould 5 is located at forging open end is big, the other end is straight
Diameter is small；The diameter that positioning chamber is located at one end of forging open end is small.
Or it be conical lower end is cylindrical, conical diameter that the outer surface of left mould 4 and the molding composition of right mould 5, which is upper end,
It is up big and down small；Sleeve mold 3 is set outside left mould 4 and right mould 5, setting and 5 outer surface corresponding matching of left mould 4 and right mould in sleeve mold 3
To position and clamp the positioning chamber of left mould 4 and right mould 5；Positioning chamber is open at one end or both ends open.Outside left mould 4 and right mould 5
Surface lower portions are cylinder, and positioning chamber lower end is also that cylinder is corresponding to it, and are equivalent to seam allowance positioning.The height of seam allowance positioning can
Think 20 millimeters.Left mould 4 is identical with 5 shape of right mould.It is very close to each other between contact surface after left 4 right mould 5 of mould compresses.By flat cylinder bottom
It is divided into symmetrical two halves, Zuo Mo 4 and right mould 5 are corresponding with the half of flat cylinder bottom respectively.Left mould 4 and right mould 5 mold the circle of outer surface
Conical tapers are 7 °, and corresponding positioning chamber taper is also 7 °.(or other taper.)
When it is implemented, left mould 4 and right mould 5 are combined be put into sleeve mold 3 position and compress, with open die forging forging hammer from
Forging forges downwards flat cylinder bottom above open end.After the completion of forging, workpiece is taken out.Need to forge different band steel bottoms, replacement pair
The left mould and right mould answered.
Using the utility model structure, do not have to blocking base, guarantees a fiery one-pass molding, cost savings 2%-4%.Split run produces
For amount in 400-500 part, efficiency improved 2-3 times compared to before, manufacturing cost accordingly by half more than.Forging stock utilization is high,
The cylinder bottom of different size, stock utilization is 87% ~ 95%.Mould structure is simple, does not redesign flash gutters, guiding, mold dovetail
Deng die manufacturing cost is low.Forging any surface finish is smooth, accurate size.Mold have extremely strong interchangeability, a sleeve mold,
A variety of inner core dies can cover the cylinder bottom forging of multiple specifications.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
