Description

A bending machine for processing steel structure bridges Technical Field

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

[0002] In the process of building bridges, the use of steel is essential to meet the strength requirements of the structure. The steel needs to be bent to meet the processing and construction requirements.

[0003] To address this, patent CN208787397U discloses a steel bending machine. Its structure includes a worktable, main body, storage box, warning sign, rollers, support plate, connecting rod, placement platform, and bending rod. The lower surface of the worktable is in contact with the top of the main body. A placement platform is provided, and rotating its knob drives a rotating shaft. The rotating shaft drives a main bevel gear, which in turn drives a rotating shaft via a secondary bevel gear. The rotating shaft, through a small bevel gear, drives a bevel gear, which in turn drives a worm gear. The worm gear moves a mating plate, which in turn moves a moving plate to the left. The moving plate then moves a traction plate, which in turn moves a locking block to the left. When the iron block on the locking block is in contact with the steel, the power switch is turned on, energizing the controller via a wire to the electromagnetic plate. This electromagnetic plate generates electromagnetic force, which then attracts the steel. This process can fix the steel during bending, preventing it from deviating from its position and improving the bending effect.

[0004] The steel used in bridge construction has high strength, but this device is difficult to align and bend into different arcs, thus failing to meet actual usage requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a bending machine for processing steel structure bridges, in order to solve the defect of existing bending machines that are not convenient for bending steel into different arcs with strong force.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bending machine for processing steel structure bridges, comprising a main body and a hydraulic push rod;

[0007] Hydraulic push rods are uniformly fixed on the top of the main body, and each hydraulic push rod is provided with a movable seat at its bottom end. An adjustment structure is provided below the movable seat.

[0008] A control panel is installed on the outer wall of the main body, and a limit structure is provided at the top of the main body;

[0009] The limiting structure includes a bent base set at the top of the main body and reserved slots evenly opened at the top of the main body. A clamping motor is installed on the outer wall of the main body on one side of the reserved slot. A bidirectional lead screw is set on one side of the clamping motor. Clamping blocks are evenly arranged on the outer wall of the bidirectional lead screw.

[0010] Preferably, the adjustment structure includes a bending seat disposed below the movable seat, a limiting groove is formed at the top of the bending seat, fastening bolts are evenly inserted through both sides of the limiting groove, and fixing blocks are evenly fixed on both sides of the movable seat above the bending seat.

[0011] Preferably, the fixing blocks are symmetrically distributed on both sides of the movable seat, and the fastening bolts are evenly distributed on both sides of the limiting groove.

[0012] Preferably, the fixing blocks are all disposed inside the limiting groove, and the bending seat and the fixing blocks are slidably connected through the limiting groove.

[0013] Preferably, all the fixing blocks extend into the interior of the movable seat, and all the fixing blocks are threadedly connected to the movable seat.

[0014] Preferably, the reserved slots are evenly distributed at the top of the main body, and the bidirectional lead screws are all threadedly connected to the clamping blocks.

[0015] Preferably, one side of the clamping block abuts against one side of the bending base, and the clamping block and the bending base form an engaging structure.

[0016] The present invention provides a bending machine for processing steel structure bridges, the advantages of which are:

[0017] By setting a limiting structure, the reserved slots are evenly distributed at the top of the main body, and the clamping motor is started to make the bidirectional lead screw rotate, which in turn makes the two sets of clamping blocks move towards each other on the outer wall of the bidirectional lead screw, thus facilitating the clamping and limiting of the bending base. This makes it less likely for the bending base to shift at the top of the main body, and makes it easier to disassemble and replace the bending base to meet bending requirements, thereby achieving the purpose of improving bending efficiency.

[0018] With the adjustment structure, the bending seat can easily form a sliding connection with the fixed block through the limiting groove, thereby guiding and limiting the bending seat. This makes it easy to initially position the bending seat and rotate the fastening bolt into the interior of the moving seat to install and position the bending seat, thus achieving the purpose of facilitating the disassembly and replacement of the bending seat.

Detailed Implementation

[0025] 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.

[0026] Please refer to Figures 1-5. The present invention provides a bending machine for processing steel structure bridges, including a main body 1 and a hydraulic push rod 2.

[0027] Referring to Figures 1-4, hydraulic push rods 2 are uniformly fixed to the top of the main body 1. Each hydraulic push rod 2 has a movable seat 3 at its bottom. An adjustment structure 4 is provided below the movable seat 3. The adjustment structure 4 includes a bending seat 401 located below the movable seat 3. A limiting groove 402 is provided at the top of the bending seat 401. Fastening bolts 403 are uniformly inserted through both sides of the limiting groove 402. Fixing blocks 404 are uniformly fixed to both sides of the movable seat 3 above the bending seat 401. The fixing blocks 404 are symmetrically distributed on both sides of the movable seat 3. The fastening bolts 403 are evenly spaced on both sides of the limiting groove 402. The fixing blocks 404 are all located inside the limiting groove 402. The bending seat 401 and the fixing blocks 404 are slidably connected through the limiting groove 402. The fixing blocks 404 extend into the interior of the movable seat 3 and are threadedly connected to the movable seat 3.

[0028] In the process of bridge construction, the use of various types of steel is becoming increasingly widespread. To meet the needs of steel use, it is necessary to bend the steel. By setting up an adjustment structure 4, the hydraulic push rod 2 is activated during the bending process, causing the moving seat 3 to move downward to bend the steel. In order to meet the needs of steel with different curvatures, bending seats 401 of different shapes are required for operation. The bending seat 401 and the moving seat 3 are connected by a limiting groove 402 and a fixing block 404 to form a sliding connection, which guides and initially positions the bending seat 401. The bending seat 401 is also positioned by a threaded connection between the bending seat 401 and the moving seat 3 formed by fastening bolts 403, which makes it less likely to shift position during use, thus greatly increasing the practicality of the device.

[0029] Referring to Figures 1, 2, and 5, a control panel 5 is installed on the outer wall of the main body 1. A limiting structure 6 is provided at the top of the main body 1. The limiting structure 6 includes a bending base 601 provided at the top of the main body 1 and reserved slots 602 evenly opened at the top of the main body 1. A clamping motor 603 is installed on the outer wall of the main body 1 on one side of the reserved slot 602. A bidirectional lead screw 604 is provided on one side of the clamping motor 603. Clamping blocks 605 are evenly arranged on the outer wall of the bidirectional lead screw 604. The reserved slots 602 are evenly distributed at the top of the main body 1. The bidirectional lead screw 604 is threadedly connected to the clamping block 605. One side of the clamping block 605 abuts against one side of the bending base 601. The clamping block 605 and the bending base 601 form a locking structure.

[0030] When bending steel, the steel needs to be placed, and the different sized grooves on the top of the bending base 601 facilitate the bending process. When bending steel of different sizes, the bending base 601 needs to be replaced and positioned. By setting a limiting structure 6, the bending base 601 is placed on the top of the main body 1, and the clamping motor 603 is started, causing the bidirectional lead screw 604 to rotate inside the reserved slot 602. The two sets of clamping blocks 605 are threadedly connected to the bidirectional lead screw 604, which causes the two sets of clamping blocks 605 to move towards each other on the outer wall of the bidirectional lead screw 604. This allows one side of the clamping block 605 to be placed inside the bending base 601, forming a locking structure and limiting the bending base 601. This makes it difficult for the clamping block 605 to shift position at the top of the main body 1, thus greatly increasing the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
