Method and apparatus for extraction of cemented carbide bodies from a component

Abstract

A method for recovery of at least one cemented carbide body from a component including the steps of first clamping the component in a clamping device, and then simultaneously or cyclically heating and vibrating the component to dislodge the at least one cemented carbide body from the component. Also provided is an apparatus for the recovery of at least one cemented carbide body from a component having an axial axis, the apparatus including a vibrating device arranged for vibrating the component in a vertical direction with respect to the axial axis, a clamping device arranged for positioning the component so that the cemented carbide bodies are vibrated in a vertical direction with respect to the axial axis, and at least one heating device arranged for heating of the component at the same time as vibrating the component.

1 . A method for recovery of at least one cemented carbide body from a component, the method comprising the steps of:
 a) first clamping the component in a clamping device; and   b) simultaneously or cyclically heating and vibrating the component to dislodge the at least one cemented carbide body from the component.   
     
     
         2 . The method according to  claim 1 , wherein induction heating is used to heat the component. 
     
     
         3 . The method according to  claim 1 , wherein flame heating is used to heat the component. 
     
     
         4 . The method according to  claim 1 , wherein in step b) the component is heated to a temperature of between 600-1000° C. 
     
     
         5 . The method according to  claim 1 , wherein there is an additional step, between steps a) and b) wherein the component is pre-heated before the simultaneously heating and vibrating of the component is performed. 
     
     
         6 . The method according to  claim 5 , wherein induction heating is used to pre-heat the component. 
     
     
         7 . The method according to  claim 1 , wherein the vibration of the component is controlled by compressed air. 
     
     
         8 . The method according to  claim 1 , wherein the component is rotated in a radial and/or axial direction during step b). 
     
     
         9 . A method for recovery of at least one cemented carbide body from a component, the method comprising the steps of:
 a) firstly, clamping the component in a clamping device;   b) secondly, heating the at least one cemented carbide body using induction heating; and then   c) thirdly, vibrating the component to dislodge the at least one cemented carbide body from the component.   
     
     
         10 . An apparatus for recovery of at least one cemented carbide body from a component having an axial axis, the apparatus comprising:
 a vibration device arranged for vibrating the component in a direction having an angle of less than 30° with respect to the axial axis;   a clamping device arranged for positioning the component so that the at least one cemented carbide body is vibrated in a direction having an angle of less than 30° with respect to the axial axis; and   at least one heating device arranged for heating the component at the same time as vibrating the component.   
     
     
         11 . The apparatus according to claim  11 , wherein the clamping device comprises: includes a plate having a drop-shaped opening. 
     
     
         12 . The apparatus according to  claim 10 , wherein the clamping device comprises includes a threaded component. 
     
     
         13 . The apparatus according to  claim 11 , wherein the vibration device is a compressed air-controlled vibration device. 
     
     
         14 . The apparatus according to  claim 11 , further comprising a vertical block and at least one guiding rod positioned between the vibration device and the clamping device. 
     
     
         15 . The apparatus according to  claim 11 , wherein the heating device is an induction heater.
