[0025] The mounting mechanism 9 comprises a vertical plate 91 located outside the extension plate 10, a square plate 92 is arranged on one side of the vertical plate 91, a rectangular sleeve 93 is arranged on one side of the machine 1 and is sleeved on the square plate 92, a mounting channel is arranged in the square plate 92, a screw rod 94 driven by a motor 195 is screwed in the mounting channel, a horizontal plate 96 is also arranged on the vertical plate 91 and is closely attached to the lower side of the extension plate 10, a baffle 97 located outside the extension plate 10 is arranged on the top of one end of the horizontal plate 96, and a plurality of suspension mechanisms 98 are evenly arranged on the top of the horizontal plate 97;

[0026] The suspension mechanism 98 includes a strip groove 981 arranged on the top surface of the extension plate 10, a groove 982 is arranged in the middle of the bottom of the strip groove 981, a strip plate 983 is arranged in the strip groove 981, wherein a slope 984 is arranged on the top corner edge of the strip plate 983 on the same side as the machine table 1, a T-bar 985 passing through the groove 982 and fixedly connected to the bottom end surface of the strip plate 983 is arranged below the cross plate 96, and a spring 986 is arranged on the T-bar 985 in the groove 982. In this embodiment, the top of the extension plate 10 is flush with the top surface of the machine table 1, the distance between the bottom end of the slope 984 and the top surface of the strip plate 983 is equal to the thickness of the extension plate 10, and the length of the vertical end of the T-bar 985 below the cross plate 96 is equal to the distance between the bottom end of the slope 984 and the top surface of the strip plate 983.

[0027] The support mechanism 4 includes a support plate 41 suspended on one side of the top of the receiving groove 3, wherein a rotation shaft I42 embedded in the corresponding side wall of the receiving groove 3 is provided at the bottom of the support plate 41 away from the cutting opening 5;

[0028] The cutting mechanism 2 includes a housing 21 connected to the hydraulic rod I7, a cutting wheel 23 driven by a motor II22 is arranged in the housing 21, the lower half of the cutting wheel 23 extends to the outside of the bottom of the housing 21, and the cutting wheel 23 is located directly above the cutting opening 5;

[0029] The extrusion mechanism 8 includes mounting plates 81 arranged on both sides of the shell 21, wherein each set of mounting plates 81 is provided with an electric push rod 82, and two sets of electric push rods 82 are located on both sides of the cutting opening 5, and the output shaft of the electric push rod 82 is fixed with a pressure plate 84 through a vertical rod 83, wherein an inverted L-shaped rod 85 is arranged on the vertical rod 82 located directly above the support plate 41, and a pressure block 86 located at the top of the end of the support plate 41 is arranged at the bottom end of the L-shaped rod 85.

[0030] In this embodiment, a limit plate I11 and a limit plate II12 are respectively arranged on the top of the machine 1 on both sides of the cutting opening 5. The limit plate I11 is fixed at the rear side of the top surface of the machine 1, and the limit plate II12 is located at the back of the machine 1 and the extension plate 10. A motor III13 is arranged on the back of the frame 6, and the output shaft of the motor III13 is connected to the connecting seat at the top of the back of the limit plate II12. An electromagnet block 14 magnetically connected to the bottom side wall of the limit plate II12 is arranged on the back of the extension plate 10.

[0031] In this embodiment, a U-shaped plate 15 is arranged on the back of the machine 1 and the extension plate 10. The U-shaped plate 15 is located below the extension plate 10. A U-shaped seat 16 for accommodating one end of the U-shaped plate 15 is arranged on the back of the machine 1. A rotating shaft II embedded in the side wall of the U-shaped seat 16 is arranged on both sides of the end of the U-shaped plate 15. A hydraulic rod II17 movably connected to the other side of the bottom of the U-shaped plate 15 is obliquely arranged on the back of the machine 1 below the U-shaped seat 16.

[0032] When in use, the spacing between the cutting opening 5 and the baffle plate 97 is adjusted as required, so that the spacing between the two is equal to the required final length of the steel bar. The specific steps are as follows: the motor I95 drives the screw rod 94 to rotate in the installation channel, and then drives the square plate 92 to move right in the sleeve 93, thereby driving the vertical plate 91, the horizontal plate 96 and the baffle plate 97 to move right. When the horizontal plate 96 moves right, it will drive the suspension mechanism 98 at its top to move right to the right side of the extension plate 10. Then, when the suspension mechanism 9 loses the squeezing of the extension plate 10, the spring 986 stretches to push the T-bar 985 to move upward in the through hole on the horizontal plate 96, and at the same time drives the strip plate 983 to move slowly upward in the strip groove 981, so that the top of the strip plate 983 in the suspension mechanism 98 that is displaced to the right side of the extension plate 10 is finally flush with the top surface of the extension plate 10, and its bottom end is still located in the strip groove 981. When the baffle plate 97 moves right, the vertical plate 91, the horizontal plate 96 and the baffle plate 97 are moved right. After the distance between the plate 97 and the cutting opening 5 meets the production requirements, the steel bars can be laid flat on the machine table 1, the extension plate 10 and the top of the strip plate 983 on the right side of the extension plate 10 to support and fix it. At this time, the right end of the steel bars can be against the baffle plate 97. When it is necessary to reduce the distance between the cutting opening 5 and the baffle plate 97, the motor 195 drives the vertical plate 91, the baffle plate 97 and the horizontal plate 96 to move left through the screw rod 94 and the square plate 92. The horizontal plate 96 moving to the left will drive the strip plate 983 on the suspension mechanism 98 on the right side of the extension plate 10 to move left. At this time, the bottom corner edge of the right end of the extension plate 10 will contact the bottom end of the inclined surface 984 on the strip plate 983. When the strip plate 983 continues to move left, the extension plate 10 squeezes the inclined surface, so that the inclined surface 984 slides on the bottom corner edge of the extension plate 10, so as to force the strip plate 983 to slide into the strip groove 981 and compress the spring 986.

[0033] When the steel bar is placed on the machine 1, the extension plate 10 and the strip plate 983, the limit plate I11 and the limit plate II12 can prevent the steel bar from moving backward and sliding off the above-mentioned equipment. At this time, the electric push rod 82 drives the vertical rod 83 and the pressure plate 84 to move downward, thereby squeezing and fixing the steel bars on both sides of the cutting opening 5 to prevent the steel bars from bouncing during cutting and affecting the cutting effect. The vertical rod 83 squeezes the support plate 41 through the L-shaped rod 85 and the pressure block 86, so that it rotates counterclockwise with the rotating shaft I42 as the center, and finally makes the right end of the support plate 41 in a horizontal state and supports and fixes the end of the steel bar, so that the support plate 41 and the pressure plate 84 in a horizontal state at this time play a supporting and locking role on the end of the steel bar. Then the hydraulic rod I7 drives the cutting mechanism 2 to move downward, and the steel bar is cut to a fixed length by the rotating cutting wheel 23. At this time, the electric push rod 82 shrinks at the same time to prevent the squeezing mechanism 8 from affecting the hydraulic rod I7 to drive the cutting mechanism downward, and its shrinkage amplitude and speed are the same as those of the hydraulic rod I7.

[0034] When the cutting is completed, the hydraulic rod I7 drives the cutting mechanism 2 to reset and drives the reset extrusion mechanism 8 to move upward. At this time, the extrusion mechanism 8 is lost. The cut pieces on the support plate 41 are squeezed by their own gravity to rotate the support plate 41 clockwise around the rotating shaft I42 as the center, so that the support plate 41 is tilted so that the pieces above it can slide into the receiving groove 3 for collection and recovery. At the same time, the electromagnet block 14 is powered off, and the motor III13 drives the limit plate II12 to rotate to open the back side of the machine 1 and the extension plate 10. Then, the cut steel bar can be pushed backward to slide from the top of the above-mentioned components, and the left end of the sliding steel bar will fall into the opening of the U-shaped plate 15. Then the hydraulic rod II17 contracts to make the U-shaped plate 15 rotate counterclockwise around the rotating shaft II as the center, so that the U-shaped plate 15 is tilted so that the steel bars inside it can slide to the ground, preventing the steel bars falling from the machine 1 and the extension plate 10 from falling on the ground due to a large impact force and causing damage to them, or causing damage to other equipment such as the ground.

[0035] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
