Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a steel bar bending machine for engineering construction. Background Technology

[0002] In on-site construction of building projects, steel bars are one of the essential building materials. Some steel bars need to be bent before use. Currently, apart from manual bending, existing steel bar bending equipment is usually used.

[0003] For example, CN221817212U discloses a rebar bending machine for engineering construction, including a motor installed inside the device body with a turntable at its end. The turntable is concentric with the motor's shaft. Two fixed posts are provided on the top surface of the turntable. An annular groove is provided on the top surface of the device body, and the annular groove mates with a retaining ring located on the outer periphery of the turntable and extending downwards. A guide block is provided on one side of the turntable, and a through hole is opened at one end of the guide block facing the turntable. The rebar to be bent, passing through the through hole, is tangent to the outer periphery of the fixed post located in the middle of the turntable. The through hole is connected to a guide groove located inside the guide block. The guide block of this utility model is designed as a groove, so that both sides of the fixed end of the rebar are confined inside the guide block. Simultaneously, the bending point of the rebar is located on the side of the guide block. The annular groove on the surface of the device body, which mates with the turntable retaining ring, shares the radial force experienced by the motor during bending, effectively reducing the risk of motor damage and improving operational safety.

[0004] However, in the existing technology, the bending rod of the traditional bending machine cannot be disassembled, replaced or adjusted according to actual needs. The bending rod is in direct contact with the steel bar. Because the steel bar has high hardness and a rough surface, long-term use will cause wear on the surface of the bending rod, shortening the life of the equipment, thus limiting the practicality of the device to a certain extent. Utility Model Content

Due to the high hardness and rough surface of the reinforcing bar, long-term use leads to wear on the surface of the bending rod, which shortens the life of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel bar bending machine for engineering construction, comprising a main body, supports fixedly installed at the four corners of the lower surface of the main body, a control end fixedly installed on the outer wall of the main body, a motor fixedly installed at the center of the lower surface of the main body, the output end of the motor extending through to the upper part of the main body and driving a mounting plate, a fixing column fixedly installed at the center of the upper surface of the mounting plate, a first connecting column fixedly installed at the top of the fixing column, a plurality of first reserved holes opened around the upper surface of the mounting plate, and the straight-line distance from each first reserved hole to the fixing column is unequal, a first bending rod is inserted into the interior of the first reserved hole, and the control end is connected to the motor by signal control.

[0007] In a preferred embodiment, mounting grooves are symmetrically formed on both sides of the upper surface of the main body, and first mounting holes are symmetrically formed on both ends of the upper surface of the main body near the mounting grooves.

The two ends of the inner cavity of the placement seat are symmetrically provided with second installation holes, and the second installation holes and the first installation holes are located at the same axis point.

[0009] In a preferred embodiment, a locking bolt is placed inside the second mounting hole, and the bottom end of the locking bolt is connected to the internal thread of the first mounting hole.

[0010] In a preferred embodiment, the upper surface of the placement base is provided with a plurality of second reserved holes at equal intervals, and a second bending rod is inserted into the interior of the second reserved holes.

[0011] In a preferred embodiment, a support column is inserted into the second reserved hole in the middle at the same horizontal plane as the fixing column, and a second connecting column is fixedly installed at the top of the support column.

[0012] In a preferred embodiment, a connecting plate is sleeved on the surface of the second connecting post and the first connecting post, and a baffle is fixedly provided on the lower surface of the connecting plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a steel bar bending machine for engineering construction, including a main body 1. Supports 2 are fixedly installed at the four corners of the lower surface of the main body 1. A control end 3 is fixedly installed on the outer wall of the main body 1. A motor 4 is fixedly installed at the center of the lower surface of the main body 1. The output end of the motor 4 extends through to the upper part of the main body 1 and drives a mounting plate 5. A fixing column 8 is fixedly installed at the center of the upper surface of the mounting plate 5. A first connecting column 9 is fixedly installed at the top of the fixing column 8. Several first reserved holes 6 are opened around the upper surface of the mounting plate 5, and each first reserved hole... The straight-line distances from hole 6 to fixed post 8 are all different. A first bending rod 7 is inserted into the first reserved hole 6, and the control end 3 is connected to the motor 4 by signal control. Since the first reserved holes 6 are distributed around the upper surface of the mounting plate 5, and the straight-line distance between each first reserved hole 6 and fixed post 8 is different, the first bending rod 7 can be inserted into the corresponding first reserved hole 6 to perform bending operations on steel bars of different diameters. The insertion design between the first reserved hole 6 and the first bending rod 7 allows for portable replacement of the first bending rod 7, making maintenance convenient.

[0024] like Figure 1-4 As shown, mounting grooves 12 are symmetrically provided on both sides of the upper surface of the main body 1. First mounting holes 13 are symmetrically provided at both ends of the upper surface of the main body 1 near the mounting grooves 12. Mounting blocks 14 are fitted inside the mounting grooves 12. Placement seats 15 are fixedly provided on the upper surface of the mounting blocks 14. Second mounting holes 16 are symmetrically provided at both ends of the inner cavity of the placement seats 15, and the second mounting holes 16 and the first mounting holes 13 are located at the same axis. Locking bolts 17 are placed inside the second mounting holes 16, and the bottom end of the locking bolts 17 is connected to the internal thread of the first mounting holes 13. A symmetrical layout design is adopted. Mounting grooves 12 are provided on both sides of the upper surface of the main body 1, and coaxial first mounting holes 13 are provided at the end of the grooves. Through the combination structure of the embedded mounting blocks 14 and the placement seats 15, the axial alignment design of the second mounting holes 16 and the first mounting holes 13 is used to achieve precise positioning and stable connection with the locking bolts 17.

[0025] like Figure 1-4 As shown, a number of second reserved holes 18 are equidistantly opened on the upper surface of the placement base 15. A second bending rod 19 is inserted into the interior of the second reserved hole 18. A support column 20 is inserted into the middle of the second reserved hole 18 at the same horizontal plane as the fixed column 8. A second connecting column 21 is fixedly installed at the top of the support column 20. A connecting plate 10 is sleeved on the surface of the second connecting column 21 and the first connecting column 9. A baffle 11 is fixedly installed on the lower surface of the connecting plate 10. By inserting and installing the second bending rod 19 in the second reserved hole 18 at the corresponding position, when the first bending rod 7 and the fixed column 8 work together to bend the steel bar, the second bending rod 19 can perform an auxiliary secondary bend on the bent end of the steel bar.

[0026] Working principle: In use, first insert the mounting block 14 at the bottom of the placement seat 15 into the mounting groove 12, so that the second mounting hole 16 corresponds to the axis of the first mounting hole 13. Then, tighten the locking bolt 17 through the second mounting hole 16 into the first mounting hole 13. Next, insert the support column 20 into the second bending rod 19 at the same horizontal position as the fixed column 8. Then, fit the connecting plate 10 between the first connecting column 9 and the second connecting column 21. When processing the steel bar, push the steel bar forward along the baffle 11 to the gap between the first bending rod 7 and the fixed column 8. Press the control terminal 3 to start the motor 4. The motor 4 drives the mounting plate 5 to rotate. The mounting plate 5 drives the first bending rod 7 and the fixed column 8 to rotate to perform bending operations on the steel bar. When the fixed column 8 rotates, it will synchronously drive the first connecting column 9 to rotate inside the connecting plate 10. The positions of 10 and baffle 11 will not change. When processing steel bars of different diameters, since the first reserved holes 6 are distributed around the upper surface of the mounting plate 5 and the straight distance between each first reserved hole 6 and the fixed column 8 is different, the first bending rod 7 can be inserted into the corresponding first reserved hole 6 to perform bending operations on steel bars of different diameters. The insertion design between the first reserved hole 6 and the first bending rod 7 allows for portable replacement of the first bending rod 7, making maintenance convenient. By inserting and installing the second bending rod 19 into the corresponding second reserved hole 18, when the first bending rod 7 and the fixed column 8 work together to bend the steel bar, the second bending rod 19 can perform auxiliary secondary bending on the bent end of the steel bar. Moreover, the device as a whole adopts a modular disassembly and assembly design, which facilitates subsequent maintenance and replacement, is easy to operate, and is suitable for large-scale promotion and application.
