In combination with the use, this problem is obviously a real and difficult problem to solve. All electrical equipment involved in this product is powered by an external power source.

[0030] Furthermore:

[0031] like Figures 1-3 As shown:

[0032] Based on the above: the upper surface of the movable base 101 is provided with two sets of U-shaped plates 106 on one side of the protective cover 102;

[0033] A roller 108 is provided inside the U-shaped plate 106;

[0034] Multiple sets of electric push rods 105 for raising and lowering the U-shaped plate 106 are fixedly installed on the upper surface of the movable seat 101;

[0035] A drive mechanism 2 is installed on the U-shaped plate 106, which can drive multiple sets of rollers 108 to rotate.

[0036] The drive mechanism 2 includes a servo motor 203 bolted to one side of the surface of one of the U-shaped plates 106, and sprockets 201 fixed to one side of two sets of rollers 108 by screws and a chain 202 meshing between the two sets of sprockets 201.

[0037] The output end of the servo motor 203 is fixed to one end of a set of rollers 108;

[0038] Above the two rollers 108, there is an abutment mechanism 3 that presses down on the reinforcing bars;

[0039] The abutment mechanism 3 includes a mounting plate 301 fixed to one side of the protective cover 102, two sets of abutment blocks 304 respectively corresponding to two sets of rollers 108 and set below the mounting plate 301, and telescopic sleeve rods 303 fixed between the abutment blocks 304 and the mounting plate 301 in a symmetrical arrangement.

[0040] A compression spring 302 is wound around the surface of the telescopic sleeve rod 303, and the two ends of the compression spring 302 are fixedly connected to the mounting plate 301 and the abutment block 304 respectively.

[0041] The lower surface of the contact block 304 has an arc-shaped surface;

[0042] The abutment block 304 has multiple sets of mounting grooves on one side of the arc surface, and the mounting grooves are equipped with ball bearings 305. The ball bearings 305 can roll in the mounting grooves of the abutment block 304, and the ball bearings 305 are used to reduce the friction between the steel bar and the abutment block 304.

[0043] The two ends of the roller 108 are rotatably mounted via bearings and U-shaped plates 106. Two sets of connecting plates 107 are installed between the two sets of U-shaped plates 106. The output ends of every two sets of electric push rods 105 are connected and fixed to a set of U-shaped plates 106.

[0044] In this implementation plan: When using the building steel bar cutting equipment, the steel bar is first passed between the roller 108 and the contact block 304, and then through the protective cover 102. The steel bar is cut by activating the lifting and cutting mechanism 104. While cutting downwards, the extrusion and fixing mechanism 103 is driven to extrude and fix the steel bar.

[0045] When the cut steel bars need to be moved, the electric push rod 105 is connected to an external power source. The electric push rod 105 is started to rise, which drives the U-shaped plate 106 and the connecting plate 107 to move upward. Then, the U-shaped plate 106 drives the roller 108 to move upward synchronously. The roller 108 drives the steel bars to move upward, so that the steel bars are separated from the perforated surface of the protective cover 102, avoiding contact between the steel bars and the protective cover 102, which would affect the movement of the steel bars.

[0046] As the roller 108 moves the reinforcing bar upward, the reinforcing bar comes into contact with the contact block 304 and pushes the contact block 304 upward, causing the contact block 304 to compress the telescopic sleeve 303 and the compression spring 302. At this time, the rebound force of the compression spring 302 drives the contact block 304 to press the reinforcing bar downward, thereby increasing the contact force between the reinforcing bar and the roller 108 and improving the friction. This facilitates better movement of the reinforcing bar while the roller 108 rotates, and at the same time, it prevents the cut reinforcing bar from tilting upward due to gravity. It can also limit the downward pressure of the reinforcing bar. At the same time, the setting of the ball bearing 305 can reduce the friction between the contact block 304 and the reinforcing bar while limiting the downward pressure of the reinforcing bar, and improve the driving of the reinforcing bar.

[0047] The servo motor 203 is then connected to an external power source. Starting the servo motor 203 drives a set of rollers 108 to rotate on the U-shaped plate 106. These rollers 108 then drive a set of sprockets 201 to rotate synchronously. Since a chain 202 connects the two sets of sprockets 201, the chain 202 drives the other set of sprockets 201 to rotate, thus driving the two sets of rollers 108 to rotate. As the rollers 108 rotate, friction causes the reinforcing bars to move. This operation allows the reinforcing bars to move without manual intervention for heavier bars, reducing the labor intensity of workers and improving production efficiency. The overall effect of this device is better and meets practical application requirements.

[0048] The lower surface of the contact block 304 is set as an arc surface, which can increase the contact area with the steel bar and improve the contact and pressing effect on the steel bar.

[0049] Furthermore;

[0050] In an optional embodiment, the surface of the roller 108 is provided with a rubber anti-slip pad.

[0051] In this embodiment: the surface of the roller 108 is provided with a rubber anti-slip pad, which can increase the friction with the steel bar and improve the driving effect on the steel bar.

[0052] The working principle and usage process of this utility model are as follows: When using this steel bar cutting equipment, the steel bar is first passed between the roller 108 and the contact block 304, and then through the protective cover 102. The lifting and cutting mechanism 104 is activated to cut the steel bar. Simultaneously, the pressing and fixing mechanism 103 is driven to press and fix the steel bar. When the cut steel bar needs to be moved, the electric push rod 105 is connected to an external power source. The electric push rod 105 is activated to rise, driving the U-shaped plate 106 and the connecting plate 107 upwards. The U-shaped plate 106 then drives the roller 108 upwards synchronously, and the roller 108 moves the steel bar upwards, separating the steel bar from the perforated surface of the protective cover 102, thus preventing contact between the steel bar and the protective cover 102. This affects the movement of the reinforcing bar. While the roller 108 moves the reinforcing bar upward, the reinforcing bar contacts the contact block 304 and pushes the contact block 304 upward, causing the contact block 304 to compress the telescopic sleeve 303 and the compression spring 302. At this time, the rebound force of the compression spring 302 drives the contact block 304 to press down on the reinforcing bar, thereby increasing the contact force between the reinforcing bar and the roller 108 and improving the friction. This facilitates better movement of the reinforcing bar while the roller 108 rotates, and at the same time avoids the reinforcing bar from tilting upward due to gravity after cutting. It can limit the downward pressure of the reinforcing bar. At the same time, the setting of the ball bearing 305 can reduce the friction between the contact block 304 and the reinforcing bar while limiting the downward pressure of the reinforcing bar, and improve the driving of the reinforcing bar.

[0053] The servo motor 203 is then connected to an external power source. Starting the servo motor 203 drives a set of rollers 108 to rotate on the U-shaped plate 106. These rollers 108 then drive a set of sprockets 201 to rotate synchronously. Since a chain 202 connects the two sets of sprockets 201, the chain 202 drives the other set of sprockets 201 to rotate, thus driving the two sets of rollers 108 to rotate. As the rollers 108 rotate, friction causes the reinforcing bars to move. This operation allows for the movement of heavier reinforcing bars without manual intervention, reducing the labor intensity of workers and improving production efficiency. The overall effect of this device is better and meets practical application needs.

[0054] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
