Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, and particularly relates to a steel structure processing bending machine. Background Technique

[0002] Steel structure processing is a process of processing steel into components or structures. The processes it involves include operations such as cutting, drilling, welding, bending, as well as subsequent processes such as painting and surface treatment. Steel structure processing is widely used in fields such as construction, bridges, and ships. It has advantages such as light weight, high strength, and good seismic performance. At the same time, it can also achieve modular and engineering production, improving construction efficiency and quality;

[0003] For some existing steel structure processing bending machines, one end of the steel is fixed, and then the hydraulic part is pressurized through a hydraulic pump. The telescopic end of the hydraulic cylinder extends downward to bend the steel;

[0004] There are some problems. For traditional steel structure processing bending machines, the bending point cannot be quickly adjusted before bending. At the same time, after bending, the steel adheres to the lower die and cannot be quickly removed, greatly reducing the working efficiency of workers. For this reason, we propose a steel structure processing bending machine. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, provide a steel structure processing bending machine, which is convenient for quickly adjusting and positioning the bending point of the steel, has a better bending effect, and is also convenient for the steel to be automatically demolded, greatly improving the working efficiency, and can effectively solve the problems in the background technique.

The sliding columns are respectively arranged at the left and right ends of the upper surface of the machine table. The sliding holes at the left and right ends of the sliding plate are slidably connected with the adjacent sliding columns. The middle part of the lower end of the sliding plate is fixedly connected with the upper module;

[0010] Demolding mechanism: It is arranged inside the machine table, facilitating quick adjustment of the bending points of steel, achieving better bending effects, and facilitating automatic demolding of steel, greatly improving work efficiency.

[0011] Furthermore, a control switch group is provided at the left end of the front side of the machine table. The input end of the control switch group is electrically connected to an external power supply to provide electrical connections for each electrical appliance.

[0012] Furthermore, the positioning mechanism further includes a first motor and a sliding rod. The sliding rods are respectively fixedly connected to the right end of the inner side surface of the baffle. The sliding holes at the right end of the fixing strip are respectively slidably connected to the adjacent sliding rods. The first motors are respectively arranged at the left end of the outer side surfaces of the two baffles facing away from each other. The output ends of the first motors are respectively fixedly connected to one end of the longitudinal adjacent lead screws far from the middle of the lower module. The input ends of the first motors are all electrically connected to the output end of the control switch group to provide positioning drive.

[0013] Furthermore, the bending mechanism further includes a support bar and a hydraulic cylinder. The lower ends of the support bars are respectively fixedly connected to the upper ends of the sliding columns. The hydraulic cylinder is arranged in the middle of the upper end of the support bar.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: This steel structure processing bending machine has the following advantages:

[0018] 1. First, place the steel on the upper end of the lower module. Then, adjust the control switch group. When Motor 1 operates, the output shaft of Motor 1 drives the lead screw to rotate. The rotation of the lead screw drives the fixed strip with threads to slide on the slide bar. Under the action of the sliding limit, the fixed strip slides back and forth, and the fixed strip slowly pushes the steel forward until it reaches the point to be bent, realizing the positioning of the point on the steel to be bent. Next, adjust the control switch group. The external hydraulic pump pressurizes the inside of the hydraulic column. After the hydraulic column is pressurized, its telescopic end moves downward. The hydraulic column drives the sliding plate to move downward. The sliding plate drives the upper module to move downward under the sliding action of the sliding column, and the upper module bends the steel. Then, the hydraulic column is depressurized, and its telescopic end contracts, lifting the upper module, thus realizing the bending of the steel, facilitating the quick adjustment of the point on the steel to be bent, and achieving a better bending effect.

[0019] 2. After bending the steel, under the pressing of the hydraulic column on the steel, the steel is likely to adhere to the lower module. When manually removing it, it is rather laborious. Then, by adjusting the control switch group, Motor 2 operates. The output shaft of Motor 2 drives the worm to rotate. The worm drives the engaged worm wheel to rotate, and then drives the threaded rod to rotate. The rotation of the threaded rod drives the inner threaded cylinder with threads to push upward. The upper end of the inner threaded cylinder contacts the lower end of the steel, thus lifting the steel off, facilitating the automatic demoulding of the steel and greatly improving the work efficiency.

The input ends of the first motors 42 are electrically connected to the output end of the control switch group 7. First, place the steel on the upper end of the lower module 3, and then adjust the control switch group 7. The first motor 42 operates, and the output shaft of the first motor 42 drives the lead screw 43 to rotate. The rotation of the lead screw 43 drives the threaded fixed strip 44 to slide on the slide bar 45. Under the action of sliding limit, the fixed strip 44 slides back and forth, and the fixed strip 44 slowly pushes the steel forward until the point to be bent is reached, realizing the positioning of the point to be bent of the steel;

[0028] Bending mechanism 5: It includes slide columns 51, a sliding plate 54 and an upper module 55.

The telescopic end of the hydraulic cylinder 53 is fixedly connected to the middle of the upper end of the sliding plate 54. Then adjust the control switch group 7. The external hydraulic pump pressurizes the inside of the hydraulic cylinder 53. After the hydraulic cylinder 53 is pressurized, the telescopic end of the hydraulic cylinder 53 moves downward. The hydraulic cylinder 53 drives the sliding plate 54 to move downward. The sliding plate 54 drives the upper module 55 to move downward under the sliding action of the slide columns 51. The upper module 55 bends the steel, and then the hydraulic cylinder 53 decompresses, and the telescopic end of the hydraulic cylinder 53 contracts, lifting the upper module 55, thereby realizing the bending of the steel;
