Embodiment:
A kind of saw bit matrix flattening device, as shown in Figure 1, including fuselage 1 and the platen 2 for smooth saw bit matrix, Middle platen 2 includes upper platen 21 set up and down and pressing disc 22, and pressing disc 22 and fuselage 1 are fixedly installed, and upper platen 21 is carried on the back Side from pressing disc 22 is equipped with telescoping mechanism, and telescoping mechanism uses in hydraulic cylinder 3(figure and is shown as 1 in the present embodiment), on 21 stress of platen is realized towards or away from pressing disc 22 in hydraulic cylinder 3 and is moved.It, will after quenching sawblade substrate before complete cooling Saw bit matrix is placed on pressing disc 22, and saw bit matrix makes saw blade not yet fully hardened with higher residual temperature, passes through control Hydraulic cylinder 3, so that hydraulic cylinder 3 drives upper platen 21 to move towards pressing disc 22, saw bit matrix is being pressed by the pressure of hydraulic cylinder 3 Coplanar flat is carried out in disk 2.
As depicted in figs. 1 and 2, since saw bit matrix has higher residual temperature, before saw bit matrix is tempered, saw blade base Body needs are further cooled down, and therefore, the cavity for storing coolant liquid are equipped with inside upper platen 21 and pressing disc 22 23, platen 2 is sealedly connected with the water pipe 4 being connected to cavity 23, and coolant liquid passes in and out cavity 23 by water pipe 4 and carries out to saw bit matrix It is cooling.Cavity 23 be fixed in scroll weather board 231 and weather board 231 two sides with cavity 23 up and down two A side wall is fixedly connected, and scroll weather board 231 simultaneously contradicts the two sides of weather board 231 and the two side walls up and down of cavity 23 While neither influencing coolant flow in cavity 23, the intensity of platen 21, avoids platen 2 in smooth saw bit matrix in raising Shi Shouli deformation occurs damage.
As depicted in figs. 1 and 2, during cooling, saw bit matrix transfers heat to coolant liquid and makes coolant liquid Temperature increases, to guarantee cooling effect, water pipe 4 include water inlet pipe 41 and outlet pipe 42 and water inlet pipe 41 and outlet pipe 42 respectively with The both ends of weather board 231 are oppositely arranged, and coolant liquid is flowed in cavity 23 along the track of weather board 231, The coolant liquid entered in cavity 23 from water inlet pipe 41 is flowed by hydraulic pressure along the track of weather board 231, pushes coolant liquid from water guide The outlet pipe 42 of 231 other end of plate flows out, to improve cooling effect.
As shown in figures 1 and 3, water pipe 4 is equipped with water storage box 5 away from one end of platen 2, and water storage box 5 includes cold for storing But the exocoel 52 in 51 outside of inner cavity is arranged in the inner cavity 51 of liquid and cladding, and exocoel 52 stores enough cold water to the cold of inner cavity 51 But liquid cools down, and water inlet pipe 41 connect with the sealed bottom of water storage box 5 and is connected to inner cavity 51, outlet pipe 42 and water storage box 5 End sealing connection and be connected to inner cavity 51;So that in the raised coolant liquid of temperature is flowed into from the top of water storage box 5 after heat absorption Chamber 51 has time enough to interact with the cold water progress heat in exocoel 52, bottom of the coolant liquid after steady decrease from inner cavity 51 Outflow.Water inlet pipe 41 is equipped with water pump 6, provides kinetic energy by water pump 6 for the coolant liquid in water inlet pipe 41, guarantees in cavity 23 Coolant liquid can be recycled constantly.
As depicted in figs. 1 and 2, the cylinder body of hydraulic cylinder 3 and fuselage 1 are fixedly installed, the end of 3 piston cylinder of hydraulic cylinder and upper pressure Disk 21 is vertically fixed, and hydraulic cylinder 3 drives upper platen 21 to move.For avoid in long-term use 3 stress of hydraulic cylinder bend and Prevent upper platen 21 is equipped with guide rod 11 from being directed at pressing disc 22,1 two sides opposed vertical of fuselage well, upper platen 21 is opposite The two sides of guide rod 11 extend through two trunnions 211, are existed by trunnion 211 integrally formed with trunnion 211, two guide rods 11 Sliding limits the direction of motion of upper platen 21 on guide rod 11, when platen 21 is moved towards pressing disc 22 in guarantee, Motion profile is constant.
As shown in figure 4, when needing to take out after saw bit matrix is smooth, due to saw blade by platen 2 pressure and saw blade base The contact surface of body and platen all smoothers be easy to cause saw bit matrix to be attracted on platen 2, and the outside of saw bit matrix circle It throughout setting sawtooth on week, is taken out from platen 2 for convenience of saw bit matrix, upper platen 21 is equipped with away from the side of pressing disc 22 and pushes away Part 24, pressing disc 22 are equipped with head part 25 away from the side of upper platen 21.Push piece 24 includes rocking bar 241 and push rod 242, rocking bar 241 One end and upper platen 21 upper surface it is hinged, one end of push rod 242 and the side side wall of rocking bar 241 towards upper platen 21 are cut with scissors It connects, the length of push rod 242 is greater than the thickness of upper platen 21, and push rod 242 is through upper platen 21 and is not connected to cavity 23, works as saw blade When matrix is attracted to platen 21, to contradict and incite somebody to action with saw bit matrix after 242 stress of push rod by moving rocking bar 241 downwards Platen 21 in its arrival & departure, so that saw bit matrix is separated with upper platen 21.
As shown in figure 4, head part 25 includes rocker arm 251 and mandril 252, one end of rocker arm 251 and pressing disc 22 are hinged, mandril 252 one end and the side of rocker arm 251 towards pressing disc 22 are side walls hinged, and the length of mandril 252 is greater than the thickness of pressing disc 22, Mandril 252 is through pressing disc 22 and is not connected to cavity 23.When saw bit matrix is attracted to pressing disc 22, by moving upwards Rocker arm 251 makes rocker arm 251 that mandril 252 be driven to move upwards, and mandril 252 is through pressing disc 22 and its length is greater than pressing disc 22 Thickness so that mandril 252 and saw bit matrix contradict and by its arrival & departure pressing discs 22, so that saw bit matrix divides with pressing disc 22 From.Rocker arm 251 can be moved upwards simultaneously, so that mandril 252 makes saw bit matrix jack-up between saw bit matrix and pressing disc 22 There are gaps, and saw bit matrix is facilitated to take out from platen 2.
Specific implementation process: quenched saw bit matrix is placed on pressing disc 22, is made by driving hydraulic cylinder 3 Platen 21 towards pressing disc 22 move, upper platen 21 contacted with saw bit matrix and it is started it is smooth, then opening water pump 6 make Coolant liquid is flowed in cavity 23, is cooled down to saw bit matrix.After saw bit matrix smooth cooling, hydraulic cylinder 3 is controlled So that upper platen 21 rises, if saw bit matrix is adsorbed on platen 21, hydraulic cylinder 3 is controlled again, platen 21 is declined And saw bit matrix and pressing disc 22 are contradicted, then make push rod 242 push saw bit matrix de- by moving rocking bar 241 downwards Fall platen 21;If saw bit matrix is unadsorbed on upper platen 21, the rising of platen 21 is directly controlled.It is shaken finally, moving upwards Arm 251 so that mandril 252 and saw bit matrix are contradicted and are jacked up, reserved between saw bit matrix and pressing disc 22 it is certain between Gap facilitates operator to take out saw bit matrix from platen 2, carries out next link.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
