Description

Technical Field

[0001] This utility model relates to the field of steel bar cutting technology, and in particular to a steel bar cutting device for reinforced concrete. Background Technology

[0002] A steel bar cutting device for reinforced concrete is a mechanical device specifically designed for cutting steel bars. It is used to cut steel bars to a fixed length during construction.

[0003] A search revealed Chinese patent CN109865782A, which discloses a steel bar cutting device for reinforced concrete. The device includes a support leg, a cover plate hinged to the upper right side of the operating table, a locking block pinned to one side of the cover plate via a pin shaft, a fixing block matching the locking block on one side of the operating table, a bracket on the upper left side of the operating table, a cylinder at the upper end of the bracket, and a base plate fixedly connected to the cylinder via a connecting rod.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Existing cutting equipment restricts the reinforcing bars through the operating table and cover plate, which makes it inconvenient to transport the reinforcing bars smoothly and lacks a certain clamping function. The reinforcing bars are prone to movement during cutting, resulting in a decrease in the accuracy of cutting and thus reducing the cutting efficiency. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a steel bar cutting device for reinforced concrete. The steel bar body is placed between a support wheel and a pressure wheel. Under the push of a spring, the limiting block slides downward, which drives the pressure wheel downward. The pressure wheel, in conjunction with the support wheel, clamps and transports the steel bar body. With the support of the support wheel, the steel bar body can be transported stably. When it is necessary to clamp the steel bar body, the pull rod is pulled, which drives the rotating ring to rotate. Due to the sliding arrangement of the sleeve block fixedly installed on the outer wall of the limiting frame and the outer wall of the limiting rod, under its restriction, the inclined groove opened on the outer wall of the rotating ring squeezes the sliding column, causing the slider fixedly installed at the end of the sliding column to slide inside the sliding groove opened on the inner side of the limiting frame. This causes the clamping rod fixedly installed at the end of the sliding column to move, and the six clamping rods move in a converging motion. The clamping rods clamp the outer wall of the steel bar body. At this time, the pull rod is pushed, which drives the rotating ring and the limiting frame to move in the direction of the cutting mechanism. The sleeve block fixedly installed on the outer wall of the limiting frame slides on the outer wall of the limiting rod to transport the steel bar body.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a steel bar cutting device for reinforced concrete, including a processing table, a processing mechanism above the processing table, the processing mechanism including a conveying component and a clamping component, and further including: the clamping component including four fixed plates fixedly connected to the top of the processing table, a limit rod fixedly connected to the side of each pair of fixed plates that are close to each other, a sleeve block slidably connected to the outer circumference of each of the two limit rods, a limit frame fixedly connected to the side of the two sleeve blocks that are close to each other, a rotating ring provided in the middle of the limit frame, multiple inclined grooves opened on the rotating ring, multiple sliding grooves opened on the limit frame, sliders slidably connected to the multiple sliding grooves, sliding columns fixedly connected to the multiple sliders, one end of each sliding column extending into the inclined groove, and a clamping rod fixedly connected to the other end of each sliding column.

[0008] In some embodiments, a tie rod is fixedly connected to the outer wall of the swivel.

[0009] In some embodiments, the conveying assembly includes four upright plates fixedly connected to the top of the processing table. Each pair of upright plates is rotatably connected to a support wheel on the side closest to each other. Each of the four upright plates has a limit groove, and each of the four limit grooves is slidably connected to a limit block. Each pair of limit blocks is rotatably connected to a pressure wheel on the side closest to each other.

[0010] In some embodiments, the top inner walls of the four limiting grooves and the tops of the four limiting blocks are respectively fixedly connected with springs.

[0011] In some embodiments, a cutting mechanism is fixedly installed on the top surface of the processing table, and a steel bar body is provided below the cutting mechanism.

[0012] In some embodiments, the top surface of the processing table is provided with a through groove.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] 1. This reinforced concrete rebar cutting device comprises a clamping assembly. When cutting the rebar, it is clamped and transported by the clamping assembly. When transporting the rebar, pulling the pull rod causes the rotating ring to rotate. Due to the sliding arrangement of the sleeve block fixed to the outer wall of the limiting frame and the outer wall of the limiting rod, the inclined groove on the outer wall of the rotating ring compresses with the sliding column, causing the slider fixed to the end of the sliding column to slide inside the groove on the inner side of the limiting frame. This causes the clamping rod fixed to the end of the sliding column to move, and the six clamping rods converge, clamping the outer wall of the rebar. At this time, pushing the pull rod causes the rotating ring and the limiting frame to move towards the cutting direction. The mechanism moves in the direction of movement. The sleeve block fixedly installed on the outer wall of the limiting frame slides on the outer wall of the limiting rod to transport the steel bar body. When the steel bar body is transported to the bottom of the cutting mechanism, the cutting work can be carried out. After the cutting is completed, the pull rod is pushed in the opposite direction, so that the inclined groove opened on the outer wall of the rotating ring is squeezed against the sliding column. Under the sliding restriction of the slider and the sliding groove, the clamping rod can be made to open. The clamping rod no longer clamps the steel bar body. Pushing the pull rod away from the cutting mechanism can transport the steel bar body again. This structure does not require the operator to hold the steel bar body for transport. Under the clamping restriction of the clamping rod, the movement of the steel bar body during cutting can be avoided, making the cutting of the steel bar body more precise.

[0015] 2. The steel bar cutting device for reinforced concrete consists of a conveying assembly. When it is necessary to cut the steel bar body, it is placed between the support wheel and the pressure wheel. Under the push of the spring, the limiting block slides downward. The limiting block drives the pressure wheel downward. The pressure wheel, together with the support wheel, clamps and conveys the steel bar body. With the support of the support wheel, the steel bar body can be conveyed stably.

[0016] This invention solves the problem that existing cutting equipment restricts the reinforcing bars through the operating table and cover plate, making it inconvenient to smoothly transport the reinforcing bars and lacking certain clamping functions. As a result, the reinforcing bars are prone to movement during cutting, leading to a decrease in cutting accuracy and thus reducing the cutting efficiency. Attached Figure Description

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an improved steel bar cutting device for reinforced concrete. The technical solution of this utility model is as follows:

[0028] like Figures 1-6As shown, a steel bar cutting device for reinforced concrete includes a processing table 1. A processing mechanism 4 is provided above the processing table 1. The processing mechanism 4 includes a conveying component 41 and a clamping component 43. The clamping component 43 includes four fixed plates 411 fixedly connected to the top of the processing table 1. Limiting rods 412 are fixedly connected to the sides of every two fixed plates 411 that are close to each other. Sleeve blocks 413 are slidably connected to the outer circumferential walls of the two limiting rods 412. Limiting frames 414 are fixedly connected to the sides of the two sleeve blocks 413 that are close to each other. A rotating ring 418 is provided in the middle of the limiting frame 414. Multiple inclined grooves 419 are provided on the rotating ring 418. Multiple sliding grooves 415 are provided on the limiting frame 414. Sliding sliders 416 are slidably connected to the multiple sliding grooves 415. Each block 416 is fixedly connected with a sliding column 417. One end of each sliding column 417 extends into the inclined groove 419, and the other end of each sliding column 417 is fixedly connected with a clamping rod 421. When the rotating ring 418 rotates, the sleeve block 413 fixedly installed on the outer wall of the limiting frame 414 slides against the outer wall of the limiting rod 412. Under its restriction, the inclined groove 419 on the outer wall of the rotating ring 418 squeezes against the sliding column 417, causing the slider 416 fixedly installed at the end of the sliding column 417 to slide inside the sliding groove 415 opened on the inner side of the limiting frame 414. This causes the clamping rod 421 fixedly installed at the end of the sliding column 417 to move, and the six clamping rods 421 move together. The clamping rods 421 clamp the outer wall of the steel bar body 5. The clamping assembly 43 facilitates the clamping of the steel bar.

[0029] like Figure 3 As shown, in one embodiment, a pull rod 420 is fixedly connected to the outer wall of the rotating ring 418; the pull rod 420 facilitates the movement of the rotating ring 418.

[0030] like Figure 4 and Figure 5 As shown, in one embodiment, the conveying assembly 41 includes four upright plates 431 fixedly connected to the top of the processing table 1. Each pair of upright plates 431 is rotatably connected to a support wheel 432 on the side that is close to each other. Each of the four upright plates 431 has a limit groove 433. Each of the four limit grooves 433 is slidably connected to a limit block 434. Each pair of limit blocks 434 is rotatably connected to a pressure wheel 436 on the side that is close to each other. The conveying assembly 41 facilitates the conveying of steel bars.

[0031] like Figure 6 As shown, in one embodiment, the top inner walls of the four limiting grooves 433 and the tops of the four limiting blocks 434 are respectively fixedly connected with springs 435; the setting of springs 435 facilitates the reciprocating motion of the limiting blocks 434.

[0032] like Figure 1As shown, in one embodiment, a cutting mechanism 3 is fixedly installed on the top surface of the processing table 1, and a steel bar body 5 is provided below the cutting mechanism 3; the setting of the cutting mechanism 3 facilitates the cutting of the steel bar body 5.

[0033] like Figure 1 As shown, in one embodiment, a through groove 2 is provided on the top surface of the processing table 1; the through groove 2 facilitates the removal of waste chips after cutting.

[0034] The specific working method is as follows: When it is necessary to cut the steel bar body 5, place the steel bar body 5 between the support wheel 432 and the pressure wheel 436. Under the push of the spring 435, the limiting block 434 slides downward. The limiting block 434 drives the pressure wheel 436 downward. The pressure wheel 436, in conjunction with the support wheel 432, clamps and transports the steel bar body 5. With the support of the support wheel 432, the steel bar body 5 can be transported stably. When it is necessary to clamp the steel bar body 5, pull the pull rod 420. It drives the rotating ring 418 to rotate. Due to the sliding arrangement of the sleeve block 413 fixedly installed on the outer wall of the limiting frame 414 and the outer wall of the limiting rod 412, under its restriction, the inclined groove 419 opened on the outer wall of the rotating ring 418 is squeezed against the sliding column 417, causing the slider 416 fixedly installed at the end of the sliding column 417 to slide inside the sliding groove 415 opened on the inner side of the limiting frame 414, causing the clamping rod 421 fixedly installed at the end of the sliding column 417 to move. The six clamping rods 421 move in a converging motion, clamping... Rod 421 clamps the outer wall of the rebar body 5. At this time, push the pull rod 420 to drive the rotating ring 418 and the limiting frame 414 to move towards the cutting mechanism 3. The sleeve block 413 fixedly installed on the outer wall of the limiting frame 414 slides on the outer wall of the limiting rod 412 to transport the rebar body 5. When the rebar body 5 is transported to the bottom of the cutting mechanism 3, the cutting work can be carried out. After the cutting is completed, push the pull rod 420 in the opposite direction to make the inclined groove 419 on the outer wall of the rotating ring 418 squeeze with the sliding column 417. Under the sliding restriction of the slider 416 and the sliding groove 415, the clamping rod 421 can be opened. The clamping rod 421 no longer clamps the rebar body 5. Push the pull rod 420 away from the cutting mechanism 3 to transport the rebar body 5 again. This structure does not require the operator to hold the rebar body 5 for transport. Under the clamping restriction of the clamping rod 421, the movement of the rebar body 5 during cutting can be avoided, making the cutting of the rebar body 5 more accurate.

Matters not covered in this utility model are common knowledge to those skilled in the art.
