Description

Technical Field

[0001] The utility model is applicable to the technical field of steel component processing, in particular to a bending machine for steel component processing. Background Art

[0002] At present, steel components refer to steel structure composite components that can bear and transfer loads and are connected by cold bending or welding processes such as steel plates, angle steels, channel steels, and I-beams. Before the steel structure is combined and connected, the steel is generally bent and cut so that the individual steel parts can be adapted for connection. A bending machine is a mechanical equipment used for bending high-hardness materials such as steel.

[0003] However, when using a bending machine to bend steel components, the steel component to be bent is inserted into two sets of guide rollers and rotating rollers, and the steel component is pushed and bent by the rotation of the rotating roller on one side. In this process, the spacing between multiple sets of rollers cannot be adjusted for steel components of different diameters. As a result, when the rotating roller is performing rotational bending, the bending angle is easily insufficient due to insufficient squeezing force on the outer wall of the steel component, which affects the bending quality of the steel component. Therefore, a bending machine for steel component processing is proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide a bending machine for processing steel components, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A hollow frame is fixedly mounted on the side surface of the bottom of the processing table, a transmission mechanism is provided inside the hollow frame, and a first mounting bracket is slidably mounted on both ends of the side of the bottom of the processing table close to the hollow frame, a rotating roller is rotatably sleeved on the top of the first mounting bracket through a bearing, and the rotating roller is movably arranged on the top surface of the processing table;

[0008] A pushing mechanism is provided on the outer side of the first mounting frame, and the pushing mechanism is transmission-connected to the transmission mechanism.

[0009] By adopting the above technical solution, the two sets of first mounting frames and the guide rollers on their tops can be driven to move horizontally synchronously through the transmission action of the transmission mechanism and the pushing mechanism, and the spacing between the guide rollers, the bending rollers and the rotating rollers can be adjusted to ensure that steel components of different diameters can be guided and quickly bent, thereby improving the bending applicability of the overall mechanism.

[0010] As an optional solution to the technical solution of the present application, the transmission mechanism includes a bidirectional screw and a transmission sleeve, the bidirectional screw is rotatably installed on the middle end of the inner side of the hollow frame through a bearing, a servo motor is fixedly installed on the side surface of the hollow frame, and the side of the servo motor transmission shaft is fixedly connected to the outer side of the bidirectional screw through a coupling, and the outer end surfaces of the bidirectional screw are movably sleeved with a transmission sleeve, and each of the outer middle end surfaces of the transmission sleeve is fixedly installed with a sliding block, and the sliding block is slidably inserted into the inside of the side of the hollow frame.

[0011] By adopting the above technical solution, the two sets of transmission sleeves can be driven to move synchronously toward each other or horizontally relative to each other under the rotation action of the bidirectional screw on the transmission sleeve.

[0012] As an optional solution of the technical solution of the present application, the pushing mechanism includes a transmission rod, and a connecting frame is fixedly installed on the outer side of each sliding block and the side surface of the first mounting frame, and the two ends of the side of the transmission rod are hinged to the outer side of the connecting frame through a rotating shaft, and guide grooves are provided inside the two ends of the side of the hollow frame, and the sliding block is slidably inserted into the guide grooves, and limiting grooves are provided inside the two ends of the side of the processing table, and the top of the first mounting frame is slidably inserted into the limiting grooves.

[0013] By adopting the above technical solution, the horizontal moving force of the transmission sleeve can be converted into a driving force for the first mounting bracket through the transmission conversion action of the transmission rod.

[0014] As an optional solution to the technical solution of the present application, a driving motor is fixedly installed on the bottom side of the processing table, a pushing rod is fixedly installed on the top surface of the driving motor transmission shaft, a second mounting bracket is slidably installed on the bottom side of the processing table, and the bending roller is rotatably sleeved on the outside of the second mounting bracket, the side of the pushing rod is fixedly connected to the bottom surface of the second mounting bracket, a sliding groove is opened inside the side of the processing table, and the top of the second mounting bracket is slidably inserted into the sliding groove.

[0015] By adopting the above technical solution, the second mounting frame and the bending roller can be driven to rotate synchronously through the structural function of the driving motor to perform bending processing on the steel member.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A bending machine for processing steel components according to the technical solution of the present application is provided with a hollow frame at the bottom of the processing table and a bidirectional screw rod inside the hollow frame. Combined with the rotational transmission action of the bidirectional screw rod on the transmission sleeve, the two groups of transmission sleeves can be synchronously moved horizontally toward or relative to each other inside the hollow frame, and then the two ends of the transmission rod are respectively connected to the first mounting frame and the outer side of the transmission sleeve in combination with the rotating shaft, so that the transmission rod can convert the horizontal movement force of the transmission sleeve into a horizontal push-pull force on the two groups of first mounting frames, and then drive the two groups of first mounting frames and the guide rollers on their tops to move horizontally synchronously, and adjust the spacing between the guide rollers, the bending rollers and the rotating rollers to ensure that steel components of different diameters can be guided and quickly bent, thereby improving the bending applicability of the overall mechanism.

[0018] 2. The technical solution of the present application is a bending machine for processing steel components. Through the guiding sliding action of the guide groove on the sliding block, and the guiding sliding action of the limit groove on the first mounting frame, when the bidirectional screw rotates, the transmission sleeve can only move horizontally toward or relative to each other, and the first mounting frame and the rotating roller can move horizontally outside the processing table, thereby avoiding arbitrary lateral displacement of the first mounting frame and the rotating roller to affect the bending quality of the steel component.

[0024] In this technical solution (through Figure 1 、 Figure 2 and Figure 3 As shown), a pushing mechanism is provided on the outside of the first mounting frame 24, and the pushing mechanism and the transmission mechanism are connected in transmission. The pushing mechanism includes a transmission rod 26. A connecting frame 25 is fixedly installed on the outside of each sliding block 23 and the side surface of the first mounting frame 24, and the two ends of the side of the transmission rod 26 are hinged to the outside of the connecting frame 25 through a rotating shaft.
