Description

Technical Field

[0002] Engineering construction covers construction projects, line pipeline and equipment installation projects, and building decoration and renovation projects, etc., involving various forms of fixed asset formation processes such as new construction, expansion and reconstruction. The rebar bending machine is a mechanical equipment used to bend rebar into various shapes. The rebar bending machine is mainly composed of a working disk, an insert seat, a clamp, etc., and is powered by an electric motor and a gear reduction system. The rebar bending machine drives the working disk to rotate through the electric motor, and uses the interaction between the iron block shaft and the forming shaft to bend the rebar.

[0003] Publication number CN219805295U discloses a steel bar bending machine for engineering construction, comprising a workbench, one side of the top of the workbench is fixedly connected to the fixed table, the output end of the servo motor extends to the outside of the workbench and is fixedly connected to the rotating disk by a coupling. The two ends of the top of the rotating disk are fixedly connected to the fixed plate, and a slide groove is provided on the top of the rotating disk at one end of the fixed plate, and the internal sliding connection of the slide groove is connected to a sliding seat, and one end of the top of the sliding seat is movably connected to a bending column. Through the set fixed length component, the fixed length threaded rod is driven to rotate by rotating the fixed length handle, so that the fixed length screw block moves smoothly and drives the thrust plate to slide, and the accurate sliding position of the thrust plate is judged by using a ruler, so that when subsequent staff perform steel bar bending, they only need to press one end of the steel bar against one side of the thrust plate to perform bending processing, avoiding the errors caused by the traditional need for manual judgment and improving its practicality.

Since the top of the steel bar may have bulges due to burrs or shearing, the contact between the steel bar and the thrust plate will be poor, resulting in deviation in the positioning of the bending position of the steel bar.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model describes a steel bar bending machine for engineering construction, comprising a processing table 1, a fixed plate 2, a connecting cover 3 and a support plate 4. A bending mechanism 11 is installed on one side of the outer wall of the upper end of the processing table 1, and fixed plates 2 are installed on the outer walls of both sides of the processing table 1 away from the bending mechanism 11. The fixed plate 2 is internally threaded with a screw 21, a connecting cover 3 is provided on the outer wall of one side of the processing table 1, and a screw body 35 is installed on one side of the inner wall of the connecting cover 3. The outer wall of the upper end of the screw body 35 is fixed with a support plate 4, a support disk 42 is rotatably installed inside the support plate 4, and a limit disk 43 is installed on the outer wall of one side of the support disk 42.

[0031] When in use, the bending mechanism 11 bends the steel bar, and the screw body 35 can adjust the use position of the support plate 4, and the limit plate 43 can adjust the protruding length of the steel bar.

[0032] For clamping steel bars, for example, Figure 3 As shown, a slider 22 is rotatably mounted on the outer wall of one end of the screw rod 21 , and a clamping wheel 23 is rotatably mounted inside the slider 22 .

[0033] During use, the staff manually rotates the screw 21, and the screw 21 can drive the slider 22 to move horizontally, and can adjust the distance between the two clamping wheels 23 to ensure that the position of the steel bar between the clamping wheels 23 is relatively stable, and the clamping wheel 23 can clamp and fix one side of the steel bar to keep the position of the steel bar stable during the bending process, and the external motor can drive the clamping wheel 23 to rotate, which can drive the steel bar to move.

[0034] In order to fix the connection cover 3, for example, Figure 1 As shown, fixing blocks 32 are installed on both sides of the outer wall of the lower end of the connecting cover 3. Screws are provided inside the fixing blocks 32, and the fixing blocks 32 are connected to the outer wall of the processing table 1 through the screws.

[0035] When in use, the screws can fix the fixing block 32 to keep the fixing block 32 stable at the outside of the processing table 1, thereby keeping the use position of the connecting cover 3 stable.

[0036] To collect metal chips, for example, Figure 1 As shown, connecting pipes 33 equidistantly and parallelly distributed are installed on the outer walls of both sides of the connecting cover 3 . The connecting pipes 33 are designed in a curved shape, and a dust suction pipe 34 is installed on the outer wall of one end of the connecting pipe 33 .

[0037] When in use, the dust suction pipe 34 is connected to an external vacuum cleaner, and the vacuum cleaner can collect the metal debris that falls off during the grinding of the connection cover 3 through the dust suction pipe 34 and the connecting pipe 33 to prevent the metal debris from scattering.

[0038] In order to observe the inside of the connection cover 3, for example, Figure 1 As shown, a transparent plate 31 is embedded and installed on one side of the outer wall of the upper end of the connection cover 3, and the transparent plate 31 is designed in a rectangular shape.

[0039] When in use, the staff can observe the working status inside the connection cover 3 through the transparent plate 31, which helps the staff to adjust the bending process of the steel bars in time.

[0040] To drive the rotation, for example, Figure 4 As shown, the support disc 42 passes through the outer wall of one end of the support plate 4 and a motor body 41 is provided. The motor body 41 is connected to the outer wall of the support plate 4.

[0041] When in use, the motor body 41 can drive the support plate 42 to rotate in a circle, thereby adjusting the use positions of the limit plate 43 and the grinding plate 44 to ensure that the limit plate 43 and the grinding plate 44 are respectively controlled to contact the steel bars.

[0042] For grinding steel bars, for example, Figure 4 As shown, a grinding disc 44 is provided on the outer wall of the support plate 42 facing away from the limiting plate 43, and bolts 45 distributed in a circular array are provided inside the support plate 42. The grinding disc 44 is connected to the support plate 42 through the bolts 45, and the outer wall of the grinding disc 44 facing away from the support plate 42 protrudes from the limiting plate 43.

[0043] During use, the bolt 45 can fix the grinding disc 44, keeping the grinding disc 44 stable in the position outside the limit plate 43. The support plate 42 can drive the grinding disc 44 to grind and polish the end face of the steel bar. And because the grinding disc 44 protrudes from the limit plate 43, it can ensure that the steel bar is prevented from contacting the limit plate 43 during the grinding process.

[0044] When the utility model is in use, the staff takes the steel bar and passes it through the clamping wheel 23, and the staff manually rotates the screw 21, which drives the slider 22 to move horizontally, thereby achieving the purpose of adjusting the distance between the clamping wheels 23 and ensuring the squeezing force between the clamping wheels 23 and the steel bar;

[0046] The lead screw body 35 drives the support plate 4 to move horizontally, and the use position of the support disc 42 can be adjusted until the grinding disc 44 contacts one end of the steel bar, and the motor stops, and the motor body 41 drives the support disc 42 and the grinding disc 44 to rotate, so that the grinding disc 44 grinds and polishes the outer wall of one end of the steel bar, and can remove burrs or shearing bumps on the cross section of the steel bar, and can ensure the limiting accuracy of the limit disc 43 on the steel bar. During the grinding process, the vacuum cleaner can collect the metal debris that falls off the connecting cover 3 during the grinding through the dust suction pipe 34 and the connecting pipe 33 to prevent the metal debris from scattering.

[0047] The motor body 41 drives the support plate 42 to rotate, so that the limit plate 43 contacts the outer wall of the steel bar. By adjusting the position of the limit plate 43 by the screw body 35, the size of the steel bar inside the connecting cover 3 can be adjusted, thereby achieving the purpose of limiting the position of the steel bar inside the bending mechanism 11.

[0048] According to the above-mentioned position adjustment steps, the clamping wheel 23 maintains the position of the steel bar stable, and the external driving structure drives the bending mechanism 11 to rotate. The steel bar is bent through the interaction between the iron stop shaft and the forming shaft on the bending mechanism 11, and the bending angle of the steel bar can be adjusted according to the rotation angle of the bending mechanism 11.
