Description
Technical field
The invention belongs to the field of forging, the connection for specifically carrying out the mold used during Large Crankshaft upsetting production fills
It puts, improves mold linking intensity and reliability.
Background technology
Large Crankshaft upsetting be it is a kind of for produce in large size, the main production technology of low speed engine bent axle, material
After section is heated to set point of temperature, bending and upsetting operation is carried out to material section using particular manufacturing craft, so as to complete the shaping of crankshaft crank,
It is instrument important in forging process that it, which produces the intermediary form mold used, the mounting stability and reliable behavior of intermediate mold
Decide the stability of bent axle upsetting production process and product quality, due to the simplification of bolt connection mode, traditional technology is equal
The connection of intermediate mold is carried out using bolt, but is moved up and down with sliding block due to mold and is carried out after the completion of forging
During die sinking, intermediate mold will also overcome crankshaft forging to pack tightly the ejection resistance that mold cores are formed, and this resistance and module
Weight born by attachment bolt, bolt often can be deformed and be broken, and causing to stop production carries out bolt replacement, sometimes bolt fracture
Rear mold appearance inclination causes Crank shaft Damage and there are security risks.
The content of the invention
It is an object of the invention to provide a kind of coupling arrangement for large-scale Upset Forging Crankshafts forging mold and its users
Method, the device linking intensity are high, simple in structure, easy to operate, mold work stability and safe.
The technical scheme is that：
A kind of coupling arrangement for being suitable for large-scale Upset Forging Crankshafts forging mold, including a connector, the connector is in work
Font, the upper end of the connector are fixed on press ram, and the lower end of the connector sets a pair of of axis platform, the axis platform
Upper setting axis hole, coupling spindle are set in the axis hole, and the both ends of connecting shaft set circlip；The lower end of the connector is also
The corresponding boss in installation position；Connector is also in I-shaped, and including upper cross-arm and lower cross-arm, upper cross-arm sets through hole, described
Through hole connects with coupling spindle axis, and the lower section of upper cross-arm coordinates for plane and with the upper surface of boss；The top of the lower cross-arm is with setting
The upper side for putting the groove on mold is engaged；The upper surface of mold and the lower surface of connector are respectively provided with pin hole, positioning key
It is inserted into the pin hole.
The present invention further discloses the users of the coupling arrangement for being suitable for large-scale Upset Forging Crankshafts forging mold
Method,
1) coupling spindle is sequentially passed through to the axis hole and connector on connector, and mold connector is stretched out at coupling spindle both ends
Circlip is installed respectively in the circular groove of side, prevents coupling spindle from moving axially；
2) connector is rotated into top, mold is put into mold connector in the following, and 2 round positioning keys are put into mold
In the keyway of upper top surface；
3) adjustment pressure slider makes connector lower surface be contacted with top surface on mold, and positioning key enters connection simultaneously
In device in corresponding keyway；
4) connector is rotated down, connector is made to enter in the corresponding slot of mould upstream, is completed to connector and mould
The connection of tool.
It is an advantage of the invention that：Traditional structure using bolt conductance can be changed to be cut by the large-scale rectangular of connector
Face conducting structure, therefore, linking intensity are high, simple in structure, easy to operate, mold work stability and safe.
