Detailed Description
The invention is further illustrated by the following examples.
Example 1
Referring to fig. 1 to 3, the continuous automatic cutter straightening and flattening machine of the present embodiment includes a conveyor 1, a moving vehicle 2, a moving driving device 3, a bottom plate 2-1 and a flattening and straightening device 5, wherein the flattening and straightening device 5 includes a pressing plate 5-1 and a lifting driving device 5-2, the lifting driving device 5-2 is installed on the moving vehicle 2, and the lifting driving device 5-2 can drive the pressing plate 5-1 to ascend or descend, and a conveyor belt of the conveyor 1 is used for automatically conveying cutter blades and is partially located above the bottom plate 2-1 of the moving vehicle 2. When the pressing plate 5-1 is pressed downwards, the bottom plate 2-1 of the moving vehicle 2 can play a supporting role and forcibly restrain the cutter blade from being straightened and straightened, and meanwhile, the service life of the conveying belt is prolonged.
In this embodiment, the flattening and straightening device 5 is installed at the top inside the moving vehicle 2, and one end of the pressing plate 5-1 is installed downward. The bottom plate 2-1 of the moving vehicle 2 serves as a supporting device, the bottom plate 2-1 and the pressing plate 5-1 form a pair of upper and lower pressing devices capable of flattening and straightening the cutter blades, when the pressing plate 5-1 presses the cutter blades, the pressing plate, the cutter blades, the transmission belt and the bottom plate 2-1 form a sequentially stacked structure, at the moment, the transmission belt still moves, and the cutter blades, the pressing plate 5-1 and the moving vehicle 2 can be driven to move together by the movement of the transmission belt under the action of friction force. Wherein, the moving vehicle 2 is provided with wheels 2-3, the frame 6 of the conveyor 1 is provided with a sliding track 6-1 matched with the wheels 2-3, and the moving driving device 3 can drive the moving vehicle 2 to move along the frame 6 to the feeding end. In this embodiment, the bottom plate of the moving cart 2 serves as a support plate, which not only provides support for the transmission belt, but also enables the moving cart 2, the pressing plate 5-1 and the air cylinder of the flattening and straightening device 5 to move synchronously, so that the cutter blade is fully cooled and shaped while being straightened. In addition, when the lifting driving device 5-2 descends to a proper position, the pressure of the pressure plate 5-1 on the cutter blade, the transmission belt and the bottom plate is very large, the friction force between objects is very large, if the bottom plate does not move synchronously with the vehicle, the motion power of the transmission belt is insufficient to overcome the friction between the transmission belt and the bottom plate, so that the objects cannot move continuously, the bottom plate 2-1 of the embodiment moves synchronously with the moving vehicle 2, and the moving vehicle 2 is slidably mounted on the frame 6 through the sliding pair, so that although the pressure plate 5-1 gives very large pressure to the cutter blade, the transmission belt and the bottom plate 2-1 when the lifting driving device 5-2 descends to a proper position, the bottom plate 2-1 also gives a reaction force to the pressure plate 5-1, and for the moving vehicle 2 and the flattening straightening device 5 as a whole, the force between the lifting driving device 5-1 and the bottom plate 2-1 belongs to the internal force of the moving vehicle 2, the external influence is not generated, and the pressure between the wheels 2-3 of the moving vehicle 2 and the rack 6 is not influenced, namely the friction between the wheels 2-3 of the moving vehicle 2 and the rack 6 is small, so that the moving vehicle 2 can move synchronously along with the transmission belt 1-1.
In this embodiment, locomotive 2 can move towards the feed end under the drive of mobile drive arrangement 3, and locomotive 2 drives straightening device 5 automatic motion that flattens to the feed end and goes the cutter blade that flattens, so need not the manual work and will press from both sides one by one from the cutter blade manual work that heat treatment furnace 7 came out and get the transfer, with flattening straightening device 5 realization automatic movement get the material and flatten the straightening function, can replace manual operation, practice thrift the human cost, improve work efficiency.

Because the speed of the conveying belt is low, the cutter blade can be straightened and fully cooled in the process of conveying and discharging, the cutter blade is ensured not to deform any more after the pressing plate 5-1 rises and is loosened, and compared with the prior art, the straightening effect of the cutter blade is better. The lifting driving device 5-2 of the embodiment is an air cylinder, the pressing plate 5-1 is installed on a telescopic rod of the air cylinder, when the telescopic rod of the air cylinder extends downwards, the pressing plate 5-1 descends, and when the telescopic rod retracts, the pressing plate 5-1 ascends. It should be noted that the movement driving device 3 and the lifting driving device 5-2 may be an air cylinder, an oil cylinder, an electric push rod, an electric lead screw, or a driving device composed of a motor and a transmission assembly, as long as the driving device can drive the flattening and straightening device 5 and the moving vehicle 2 to move, and the flattening and straightening device 5 and the moving vehicle 2 can move to return to the initial position of the discharge port synchronously with the transmission belt.
