As shown in fig. 7, the extruding structure 9 includes a second notch 91, a first inclined surface 92, a fifth cavity 93, a second slider 94, a second inclined surface 95, a fifth elastic member 96, a third inclined surface 97, a second rotating member 98, a lever 99, and a fixing rod 910; a second notch 91 is arranged on the first extrusion block, a first inclined plane 92 is arranged on the first extrusion block, a fifth cavity 93 is arranged above the fixed port, a second slide block 94 is arranged in the fifth cavity, a second inclined plane 95 is arranged below the second slide block, a fifth elastic element 96 is arranged in the fifth cavity and used for resetting the first slide block, a third inclined plane 97 is arranged on the second slide block, a second rotating element 98 is arranged in the fifth cavity, a lever 99 is sleeved on the second rotating element, and a fixed rod 910 is arranged in the fifth cavity; the extrusion structure sets up in the fixed orifices, can be provided with a plurality ofly, set up here to one, the second breach is a incision that is located first extrusion piece section of thick bamboo wall, first inclined plane is an oblique angle in the incision, the fifth cavity is for setting up a cavity in top, the second slider is the block of a flash of electricity type, the chamfer of below is the inclined plane of second inclined plane top for the third inclined plane, the third inclined plane offsets with the one end of lever, the other end of lever supports on the dead lever, the dead lever is the block of a rectangular shape, contract at ordinary times in inside, only can stretch out by the extrusion of lever, thereby turn into the power of centre gripping with the power that the ironbar pushed in.

As shown in fig. 23, the preheating structure 4 includes a connecting rod 41, a preheating block 42, a power supply 43, a connecting port 44, and a connecting rod 45; a plurality of connecting rods 41 are arranged, wherein 4 connecting rods are arranged in pairs and are connected with the bending table and the fixing table, a preheating block 42 is sleeved on the connecting rods and can move back and forth on the connecting rods, a power supply 43 is arranged on the preheating block, a connecting port 44 is arranged on one side of the preheating block, and a connecting rod 45 is arranged on the other side of the preheating block; the connecting rods are four long-strip-shaped cylinders, the preheating blocks are rectangular sheet bodies, one ends of the preheating blocks are connectors, the other ends of the preheating blocks are connecting rods, the two preheating blocks are mutually spliced, so that the two preheating blocks can be electrified to be heated, and the preheating blocks are of movable structures and can be moved and adjusted in position on the connecting rods.

The specific operation flow is as follows:

the materials are placed in the feeding frame, the materials are stacked in the feeding frame and then enter the feeding port below the feeding frame, at the moment, the gap of the second blocking piece is positioned at the position of the feeding port, the iron bar enters the position between the third sliding chute and the fourth sliding chute and is supported by the first blocking piece, the movable preheating block 42 is moved to the position needing to be bent, the iron bar is heated, when the iron bar is processed and discharged, the material stop ring is rotated, in the rotating process, the second baffle plate moves in the fourth sliding chute to separate the lowest material from the upper material, the first baffle plate is rotated continuously to expose the gap, thereby the material falls down, gets into on the rotatory piece, space will be exposed to rotatory second separation blade afterwards to as above-mentioned, the material falls into first separation blade top and preheats, when rotatory piece resets, and the material slides down along the incision, starts afterwards and accomplishes the material loading.

The motor rotates to drive the threaded rod to rotate, so that the moving block sleeved on the threaded rod through the threaded hole is limited by the sliding groove because the transverse block on the moving block is clamped in the first sliding groove, the moving block moves outwards, the fixed block at the other end of the moving block is continuously clamped in the notch to clamp the upper surface of the material, the splicing rod is inserted into the clamping port, the reinforcing of the moving block and the rotating block is completed together with the fixed block, the third elastic piece and the fourth elastic piece are extruded to move inwards to clamp two sides of the iron bar, the first extrusion block moves towards the inner part of the fixed port under extrusion along with the continuous extrusion of the iron bar, when the first inclined plane in the second notch on the first extrusion block contacts the second sliding block in the fifth cavity, the second sliding block moves upwards under the action between the second inclined plane and the first inclined plane, and the third inclined plane above the second sliding block abuts against one end of the lever, the other end of the lever is positioned below the fixed rod, the lever extrudes the fixed rod to move the fixed rod downwards to continuously extrude and fix the iron bars entering the fixed port in the process of continuously moving the fixed rod downwards, so that the fixation of the iron bars is reinforced, when the transverse block moves into the containing cavity, the moving block is not limited by the first sliding groove any more and can rotate, so that the moving block drives the rotating block to rotate to bend the iron bars, after the rotation is completed, the notch returns to the position of the feeding port, the rotating block is extruded by the top block, so that the notch on the rotating block is more smoothly butted with the feeding port, after the twisting is completed, the motor rotates reversely, the transverse block slides out from the containing groove and returns to the first sliding groove again, the transverse block approaches to the motor along the first sliding groove until the transverse block rotates to the bottom of the first sliding groove, at the moment, the moving block cannot continue to retreat, and rotates along the second sliding groove at, and the horizontal bar moves in the second chute, the rotation of the moving block drives the rotating block to rotate reversely, so that the notch is spliced with the blanking port, the material slides downwards along the notch to complete the blanking process, then the motor rotates forwards, the horizontal bar is preferentially jacked back to the first chute by the first sliding block under the action of the first elastic piece, the horizontal bar is matched with the feeding process described in the beginning of the process, and the process is repeated.
