Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a steel bar bending device for building construction. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete, with a circular cross section, or sometimes a square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. Since construction sites have different requirements for steel bars, construction workers will use steel bar bending devices to bend the steel bars for use.

[0003] Patent No. CN208866301U is a construction steel bar bending device, whose structure includes a box, a rotating block, a controller, a wire, a pedal transmission, a button, a turntable, a fixing plate, a motor, a power wire, a fixing device and a steel bar strength detection device. The utility model is a construction steel bar bending device, which has the beneficial effect of solving the problem that the steel bars cannot be fixed and are unstable, resulting in easy displacement of the steel bars during bending. By providing a fixing device, one end of the steel bar is placed on the upper end of the fixing groove at the upper end of the fixing frame, and then the knob is held and then rotated clockwise to drive the knob to rotate the screw rod, which is transmitted on the inner side of the fixing frame to drive the clamping block to move to the lower end to clamp the steel bar, thereby achieving the beneficial effect of being able to firmly fix the steel bar and preventing the steel bar from shifting during bending.

[0004] Due to this patent, the support surface of the operating table for the steel bars is small. When the steel bars are long, the unprocessed ends of the steel bars are easily placed on the ground and bent due to gravity, or the operator is required to manually support the steel bars, which is time-consuming and labor-intensive and inconvenient for processing and use. Utility Model Content

[0005] The purpose of the utility model is to provide a steel bar bending device for construction to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction steel bar bending device, comprising an operating table, a supporting mechanism is provided on one side of the operating table, the supporting mechanism comprises a supporting plate, fixed seats are provided on both sides of the supporting plate, and the fixed seat is fixedly connected to the operating table, rotating rods are fixedly connected to both sides of the supporting plate, and the rotating rod and the fixed seat are rotatably connected, locking tongues are relatively slidably connected inside the two fixed seats located at the bottom of the rotating rod, and the surfaces of the locking tongues and the supporting plate are abutted, sliding rods are fixedly connected to the back sides of the two locking tongues, and the sliding rods are slidably connected to the fixed seat, a locking spring is clamped between the locking tongue and the fixed seat, a bending mechanism is provided on the top of the operating table, a positioning mechanism is provided on one side of the bending mechanism, and a driving mechanism is provided between the bending mechanism and the operating table.

[0009] As a preferred implementation, the cross section of the rotating disk is a "cross" shaped structure, and the cross section of the stopper is an "L" shaped structure.

[0010] As a preferred embodiment, the driving mechanism includes a driven gear, and the driven gear is fixedly connected to the rotating disk, a power gear is meshed on one side of the driven gear, and the diameter of the power gear is larger than the diameter of the driven gear, a driving motor is installed at the bottom of the power gear, and the driving motor is fixedly connected to the operating table.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model places the steel bars to be processed on the operating table. When the steel bars are long, the support plate can support the steel bars to avoid a large area of ​​the steel bars being suspended in the air, thereby causing the steel bars to tilt up or the unprocessed ends to bend due to gravity, which affects the processing and use effects of the steel bars. The operator does not need to manually support the steel bars, which is more labor-saving. When the steel bars do not need to be supported, the sliding rods are pulled to both sides, and the sliding rods drive the lock tongues to move and contract the locking springs. When the lock tongues move to the inner side of the fixed seat, the support plate rotates downward due to gravity, thereby realizing storage and saving space.

[0015] The utility model manually rotates the handle, and the handle drives the driving screw to rotate. Under the limit of the moving block on the operating table, the moving block drives the baffle to realize linear movement, so as to adjust the position of the baffle and the bending mechanism, and then realize the bending of steel bars at different positions. The scope of use is wider, and the setting of the baffle can make the processing position of the steel bar more accurate, without the need for manual measurement and marking of the processing position, which is more time-saving and labor-saving.

When the steel bars are long, the support plate 402 can support the steel bars to avoid a large area of ​​the steel bars being suspended in the air, which causes the steel bars to tilt up or the unprocessed ends to bend due to gravity, affecting the processing and use effect of the steel bars. There is no need for the operator to manually support the steel bars, which is more labor-saving. When there is no need to support the steel bars, the sliding rods 403 are pulled to both sides, and the sliding rods 403 drive the locking tongue 405 to move and cause the locking spring 406 to retract. When the locking tongue 405 moves to the inner side of the fixed seat 401, the support plate 402 rotates downward due to gravity, thereby achieving storage and saving space.

The shape of the rotating rod 404 is convenient for the rotation and installation of the support plate 402.

[0028] Specifically, Figure 1 and Figure 3As shown, the bending mechanism 2 includes a rotating disk 201, and the rotating disk 201 is rotatably connected to the operating table 1. A fixed rod 202 is provided at the center of the rotating disk 201, and the fixed rod 202 is fixedly connected to the operating table 1.

The turning handle 302 is manually turned, and the turning handle 302 drives the driving screw 304 to rotate. Under the limitation of the moving block 305 by the operating table 1, the moving block 305 drives the baffle 301 to achieve linear movement, thereby adjusting the position of the baffle 301 and the bending mechanism 2, and then the bending of the steel bars at different positions can be achieved, and the scope of use is wider. The setting of the baffle 301 can make the processing position of the steel bars more accurate, and there is no need to manually measure and mark the processing position, which is more time-saving and labor-saving.

When the steel bar is long, the support plate 402 can support the steel bar to avoid a large area of ​​the steel bar being suspended in the air, thereby causing the steel bar to tilt up or the unprocessed end to be bent due to gravity, affecting the processing and use effect of the steel bar. There is no need for the operator to manually support the steel bar, which is more labor-saving. When there is no need to support the steel bar, pull the sliding rod 403 to both sides, and the sliding rod 403 drives the locking tongue 405 to move and make the locking spring 40 6 retracts, when the locking tongue 405 moves to the inner side of the fixing seat 401, the supporting plate 402 rotates downward due to gravity, thereby realizing storage and saving space. After the steel bars are placed, the driving motor 503 is controlled to work, and the driving motor 503 drives the driven gear 501 to rotate through the power gear 502, thereby realizing the rotation of the rotating disk 201. During the rotation of the rotating disk 201, under the joint action of the bending rod 203 and the fixing rod 202, the steel bars are bent. The turning handle 302 is manually turned, and the turning handle 302 drives the driving screw 304 to rotate. Under the limit of the moving block 305 on the operating table 1, the moving block 305 drives the baffle 301 to realize linear movement, thereby adjusting the positions of the baffle 301 and the bending mechanism 2, and then the bending of the steel bars at different positions can be realized. The scope of use is wider, and the setting of the baffle 301 can make the processing position of the steel bars more accurate, without the need to manually measure and mark the processing position, which is more time-saving and labor-saving.
