The slider 453 is sleeved on the outer side of the slide bar 44 and is slidably connected to the slide bar 44. An avoidance hole 454 is opened at the position of the slider 453 relative to the support sheet 431, and the height of the avoidance hole 454 is smaller than the diameter of the slide bar 44.

[0046] The vertical plate 452 is located below the horizontal plate 451 and has a sliding hole 455 horizontally formed therein, and a second clamping block 456 is horizontally formed inside the sliding hole 455, and the second clamping block 456 is slidably connected to the vertical plate 452. When the second clamping block 456 extends below the horizontal plate 451, the first clamping block 42 and the second clamping block 456 are opposite to each other, so that the belt body 412 drives the first clamping block 42 to move, and then the first clamping block 42 drives the second clamping block 456 to move, and the second clamping block 456 drives the driving block 45 to move. When the second clamping block 456 slides out of the sliding hole 455, the first clamping block 42 and the second clamping block 456 are staggered, and the first clamping block 42 cannot drive the second clamping block 456 to move.

[0047] Reference Figure 6 , Figure 7 The frame 411 is vertically provided with a block unloading plate 46 at a position below the conveyor belt 41, and the block unloading plate 46 is opposite to the second clamping block 456 located below the conveyor belt 41.

[0050] Reference Figure 3 , Figure 8 When the driving block 45 moves to the position of the unloading plate 46, the second block 456 on the driving block 45 is opposite to the unloading plate 46, and the hydraulic rod of the first hydraulic cylinder 461 drives the unloading plate 46 to move toward the side close to the center of the belt body 412, so that the unloading plate 46 pushes the second block 456 to move toward the side away from the center of the belt body 412, so that the first block 42 and the second block 456 are staggered. The driving block 45 located on the side close to the tail end below the conveyor belt 41 pushes the driving block 45 opposite to the unloading plate 46 to move toward the side close to the head end, so that the unloading plate 46 staggers the second block 456 with the first block 42. When the driving block 45 is opposite to the upper plate 47, the hydraulic rod of the second hydraulic cylinder 471 drives the upper plate 47 to move toward the side close to the center of the belt body 412, and the upper plate 47 drives the second baffle plate 48 to move toward the side close to the center of the belt body 412, so that the first clamping block 42 and the second clamping block 456 are opposite to each other, and then the driving block 45 can be driven to move. The length of the cut steel bar 2 is adjusted by controlling the time interval between the two extensions of the hydraulic rod of the second hydraulic cylinder 471 of the upper plate 47.

[0051] Reference Figure 3 , Figure 5Two clamping plates 49 are arranged opposite to each other on the side of the transverse plate 451 away from the belt body 412.

The side of the clamping plates 49 close to the steel bar 2 is an arc structure, and the center of the arc of the two clamping plates 49 is located between the two opposite clamping plates 49. The inner side walls of the two opposite clamping plates 49 are fixedly connected with a fixing rib 491. The fixing rib 491 is a threaded structure, and the spiral of the fixing rib 491 is the same as the spiral of the transverse rib 21 on the outer side wall of the steel bar 2.

[0052] A bidirectional lead screw 492 is horizontally arranged inside the horizontal plate 451, and the bidirectional lead screw 492 is rotatably connected to the horizontal plate 451, and the axis of the bidirectional lead screw 492 is parallel to the direction of the line between the two opposite clamping plates 49.

A third rotating motor 493 is fixedly connected to one end of the horizontal plate 451 relative to the bidirectional lead screw 492, and the motor shaft of the third rotating motor 493 is coaxial with the bidirectional lead screw 492 and fixedly connected.

[0053] The bidirectional lead screw 492 is driven by the third rotating motor 493 to rotate, so that the bidirectional lead screw 492 drives the two opposite clamping plates 49 to move in a direction of being relatively close to or relatively away from each other, thereby clamping the steel bar 2 through the two clamping plates 49.

[0054] A position sensor 410 is fixedly connected to one side of the top of the support frame 43 near the head end of the conveyor belt 41 and near the straightening plate 1. The position sensor 410 can detect the driving block 45 located on the conveyor belt 41. When the position sensor 410 detects the driving block 45 on the conveyor belt 41, the position sensor 410 controls the third rotating motor 493 on the driving block 45 located at the tail end above the belt body 412 to rotate, so that the third rotating motor 493 drives the bidirectional lead screw 492 to rotate, and then the bidirectional lead screw 492 drives the relative clamping plate 49 to move in a relatively divergent direction.

[0055] The cutting structure 5 includes a support plate 51 fixed on the frame 411, the top of the support plate 51 extends above the center of the belt body 412, and a lifting screw 52 is vertically arranged on the support plate 51, the lifting screw 52 is rotationally connected to the support plate 51, and a fourth rotating motor 53 is arranged on the top of the lifting screw 52, ​​and the motor shaft of the fourth rotating motor 53 is coaxially and fixedly connected to the lifting screw 52.

[0056] When the fourth rotating motor 53 drives the lifting screw 52 to rotate, the lifting screw 52 drives the lifting block 54 to move downward, and then the lifting block 54 drives the fifth rotating motor 55 to move downward, so that the fifth rotating motor 55 drives the cutting knife 56 to rotate, thereby cutting the steel bar 2 through the cutting knife 56.

[0057] The implementation principle of the steel bar straightening and cutting machine in the embodiment of the present application is: the hydraulic rod of the second hydraulic cylinder 471 pushes the upper plate 47 to move toward the side close to the center of the belt body 412, so that the first clamping block 42 and the second clamping block 456 are opposite, and the baffle 48 is retracted by the hydraulic rod of the third hydraulic cylinder 481, so that the belt body 412 drives the driving block 45 to move.

[0058] The fourth rotary motor 53 drives the lifting screw 52 to rotate, so that the lifting screw 52 drives the lifting block 54 to move downward, and the lifting block 54 drives the cutting knife 56 to move downward to cut the steel bar 2.

[0059] When the driving block 45 moves to the bottom of the position sensor 410, the position sensor 410 controls the third rotating motor 493 on the driving block 45 at the tail end above the conveyor belt 41 to rotate, and the third rotating motor 493 drives the two clamping plates 49 to move in opposite directions to release the steel bar 2. At this time, the driving block 45 located below the position sensor 410 drives the steel bar 2 to move toward the side away from the straightening plate 1 to straighten the steel bar 2.

[0060] After releasing the steel bar 2, the driving block 45 moves to the position of the unloading plate 46 driven by the belt body 412, and the first clamping block 42 and the second clamping block 456 are staggered by the unloading plate 46, so that the belt body 412 cannot move to drive the driving block 45 to move.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
