The specific implementation process is as follows: the tool in the embodiment is arranged on a workbench 1 of a forging machine tool, a bottom plate 2 and the workbench 1 are fixed through bolts, a pressing plate 3 is arranged on a hydraulic machine, before machining, a red workpiece is horizontally placed on a discharging lever 12, the end part of the workpiece is abutted against two cushion blocks 20, so that the workpiece is positioned, then the pressing plate 3 is driven by the hydraulic machine to move downwards, the wedge block 4 is gradually abutted against two clamping plates 5 in the downward moving process of the pressing plate 3, the two clamping plates 5 respectively move along the inclined surfaces of the wedge block 4 to generate a mutually folded state in the continuous downward pressing process of the pressing plate 3 due to the inclined surfaces of the wedge block 4, so that the two clamping plates 5 clamp the workpiece, in the process, a mandril 15 generates downward pressure on a piston 10, so that a spring 11 is compressed, and the discharging lever 12 moves downwards to be far away from the workpiece, thereby playing the role of avoiding the two clamping plates 5 and effectively avoiding the situation that the discharging lever 12 is clamped.

In addition, the pressing plate 3 also enables the upper cutting film 17 and the lower cutting film 16 to be mutually matched in the process of pressing downwards, the workpiece is punched to form two V-shaped grooves which are symmetrical up and down, so that the material scratching effect is achieved, the upper cutting film 17 and the lower cutting film 16 are processed into a fork-shaped groove structure for the workpiece, and in the process, the pressing plate 3 presses downwards, so that the two rotating blocks 22 rotate, the two discharging check blocks 19 are far away from the workpiece, the lower cutting film 16 is avoided, and the discharging check blocks 19 and the cushion blocks 20 are prevented from being pressed.

The processes of flattening the workpiece and processing the groove are carried out simultaneously, the processing efficiency can be effectively improved, and meanwhile, because the two processes are combined into one process and processed in the same tool, the problem that the position precision is not high due to twice positioning and the processing precision is influenced is avoided.

Example two

As shown in fig. 4, the material dividing and flattening tool is different from the first embodiment in that: splint 5 all includes clamp flat piece 502 and flattens piece 501 in this embodiment, and clamp flat piece 502 all rotates with mount table 7 through cylindric lock 8 to be connected, flattens piece 501 and presss from both sides flat piece 502 to dismantle and be connected, and flatten piece 501 and press from both sides flat piece 502 in this embodiment and pass through the fixed connection of dismantling of bolt realization.

The upper part of the clamp flat block 502 is rotatably connected with a roller 6 through a pin shaft, and the wedge block 4 can be contacted with the roller 6 when moving downwards.

Referring to fig. 5 and 6, the inner sides of the wedges 4 are detachably connected with backing plates 24, in this embodiment, the backing plates 24 and the wedges 4 are detachably connected in a fixed manner by bolts, guide grooves 25 are formed in the backing plates 24, and when the backing plates 24 contact with the flat clamping blocks 502, the rollers 6 are located in the guide grooves 25 and are in sliding fit with the guide grooves 25.

During the in-service use, because splint 5 comprises clamp flat piece 502 and flatten piece 501, and flatten piece 501 and the detachable connection of clamp flat piece 502, convenient in time change clamp flat piece 502 when pressing from both sides flat piece 502 and producing wearing and tearing like this, and it is convenient to change, thereby can improve the processingquality to the work piece, in addition when carrying out clamp flat to the work piece with man-hour, clamp plate 3 moves down and drives voussoir 4 and gyro wheel 6 contact, and promote two splint 5 and draw in each other, the setting up of gyro wheel 6 can reduce the frictional force of voussoir 4 and splint 5, gyro wheel 6 can slide in the guide way 25 on backing plate 24 simultaneously, thereby make the guide way 25 play the effect of direction to drawing in of splint 5, make voussoir 4 can more steady drive two splint 5 draw in and carry out clamp flat to the work piece.
