The automatic sawing machine of the invention has the following operation processes:

when the raw material steel bar needs to be sawed, the movable sawing mechanism 3 is controlled to move from the initial position to the designated position, in the process, the movable sawing mechanism 3 drives the movable trolley 4 (two movable trolleys 4 in the embodiment) to move to the designated position by times (namely, the distance between two adjacent movable trolleys in the movable sawing mechanism 3 and the movable trolley 4 is the same, a moving distance 3:2:1 is formed), the steel bar conveying mechanism 6 moves along with the movable sawing mechanism 3, and the auxiliary feeding mechanism 7 contracts along with the movement of the movable sawing mechanism 3, as shown in fig. 1 and 2.

After the movable sawing mechanism 3 reaches the designated position, a raw material steel bar is placed on the first discharging arm 2b of the movable sawing mechanism 3, the trolley discharging arm 48 of the movable trolley 4 and the second discharging arm 37 of the fixed sawing mechanism 2 (the specific placement mode can be manual feeding, or feeding by a feeding device, which is not described again). And then, the raw material aligning cylinder 2c on the fixed sawing mechanism 2 drives the raw material aligning plate 2d to align the raw material reinforcing steel bars and enable the end parts of the raw material reinforcing steel bars to be positioned on one side, close to the first clamp 26, of the first aligning plate 29, and after the alignment is finished, the raw material aligning cylinder 2c drives the raw material aligning plate 2d to return to the original position. In the process, the jacking and feeding device of the feeding mechanism 5 and the jacking and moving device of the movable trolley 4 are positioned below the discharging arm, so that preparation is made for subsequent jacking and moving of the original steel bars.

After the alignment of the original steel bars is finished, the feeding jacking cylinder 58 of the feeding mechanism 5 drives the feeding jacking plate 59 to jack the original steel bars to a preset distance, meanwhile, the trolley jacking cylinder 4g of the movable trolley 4 synchronously drives the trolley jacking plate 4h to jack the original steel bars to the preset distance, namely, the jacking distance of the trolley jacking plate 4h is the same as that of the feeding jacking plate 59, and the feeding jacking plate 59 on the movable sawing and cutting mechanism 3, the fixed sawing and cutting mechanism 2 and the trolley jacking plate 4h of the movable trolley 4 jack the steel bars to the preset distance together.

Then the feeding motor 52 of the feeding mechanism 5 on the movable sawing mechanism 3 and the fixed sawing mechanism 2 drives the feeding jacking plate 59 to move, so that the feeding jacking plate 59 drives the raw material steel bars to move to the sawing position (the sawing position comprises the sawing positions of the movable sawing mechanism 3 and the fixed sawing mechanism 2), meanwhile, the trolley moving motor 45 of the movable trolley 4 drives the trolley jacking plate 4h to move synchronously, so that the trolley jacking plate 4h drives the raw material steel bars to move to the feeding roller 43, namely, the moving distance of the trolley jacking plate 4h is the same as that of the feeding jacking plate 59.

After the raw material reinforcing steel bars move to the sawing position and the feeding roller 43, the feeding jacking plate 59 and the trolley jacking plate 4h are controlled to descend and move back to the original position, at the moment, the raw material reinforcing steel bars are placed on the first auxiliary supporting roller 28, the feeding roller 43 and the second auxiliary supporting roller 36, then the trolley feeding motor 42 drives the feeding roller 43 to rotate, the feeding roller 43 can convey the reinforcing steel bars to the fixed sawing mechanism 2 until the end parts of the raw material reinforcing steel bars are abutted to the first aligning plate 29, and conveying of the raw material reinforcing steel bars is stopped. After the end of the bar is abutted against the first aligning plate 29, the bar is clamped by the first clamp 26 of the fixed saw mechanism 2 and the second clamp 34 of the movable saw mechanism 3. Simultaneously with this operation, a second bar of raw material can be placed on the first discharge arm 2b of the mobile sawing mechanism 3, the trolley discharge arm 48 of the mobile trolley 4 and the second discharge arm 37 of the fixed sawing mechanism 2, as required. When the length of the raw material reinforcing bar is long, a part of the raw material reinforcing bar is placed on the conveying rollers 63 of the reinforcing bar conveying mechanism 6 and the auxiliary rollers 74 of the auxiliary conveying mechanism 7, at this time, the carriage feeding motor 42 of the traveling carriage 4 drives the conveying rollers 43 to rotate, and at the same time, the conveying rollers 63 are driven to rotate by the conveying motor 62 of the reinforcing bar conveying mechanism 6, so that the conveying rollers 43 and the conveying rollers 63 move the raw material reinforcing bar in the direction of the first aligning plate 29, and after the end of the raw material reinforcing bar is abutted to the first aligning plate 29, the conveying of the raw material reinforcing bar is stopped.

After the first clamp 26 and the second clamp 34 clamp the raw material steel bar, the sawing motors 24 of the first sawing device and the second sawing device are controlled to start and drive the saw blade 25 to rotate, and then the electric push rod 22 is controlled to extend out, so that the sawing motors 24 swing downwards, and the saw blade 25 saws the raw material steel bar. After the sawing operation is finished, the electric push rod 22 is retracted, the sawing motor 24 is swung upwards, and the saw blade 25 is moved out of the sawing position. At this time, the second raw material steel bar can be aligned through the raw material aligning plate 2d according to the requirement.

Later through material loading jacking board 59 and dolly jacking board 4h with the reinforcing bar after the saw cutting and the jacking of the second raw material reinforcing bar simultaneously predetermine the distance to remove material loading jacking board 59 and dolly jacking board 4h, make the second raw material reinforcing bar be moved to saw cutting position and feed roll 43 department, make the reinforcing bar after the saw cutting be moved to on the finished product rack 8 of reinforcing bar shaping place position department simultaneously. The loading lift plate 59 and the cart lift plate 4h are then lowered and moved to the home position.

A second bar of stock material is then aligned by the first alignment plate 29, clamped by the first and

second clamps

26, 34 and subjected to a double-headed sawing operation. The specific sawing process is the same as that of the first original steel bar, and is not repeated.

In this embodiment, after the bar is sawed, the stub bar of one end of the bar is collected by the scrap collecting basket 14, and if the other end of the bar is the stub bar, the stub bar is collected by moving the scrap basket 3 d. If the other end of the raw material steel bar forms the steel bar excess material, the steel bar excess material can be reused, at the moment, the material pressing cylinder 64 of the steel bar conveying mechanism 6 drives the material pressing roller 65 to compress the steel bar excess material, and meanwhile, the alignment cylinder 6e drives the second alignment plate 6f to align the steel bar excess material. The nip cylinder 64 then drives the nip rolls 65 back into position, while the alignment cylinder 6e drives the second alignment plate 6f back into position. Afterwards, the discharging air cylinder 66 of the steel bar conveying mechanism 6 drives the discharging plate 67 to jack up the steel bar remnants on the conveying rollers 63, and the steel bar remnants can slide onto the inclined plate 68 under the action of the inclined plane of the discharging plate 67, and finally slide onto the receiving bin 69 from the inclined plate 68.
