Description

Technical Field

[0001] This utility model relates to the field of hot-rolled coil technology, specifically to a hot-rolled coil bending and forming machine. Background Technology

[0002] Hot-rolled coils are made from slabs as raw materials, which are heated and then processed into strip steel by roughing and finishing mills. The hot steel strip exiting the last stand of the finishing mill is cooled to a set temperature by laminar flow and then rolled into a coil by a coiler. Hot-rolled coils have excellent properties such as high strength, good toughness, easy processing and forming, and good weldability. Therefore, they are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries. In the process of bending and forming hot-rolled coils, they are usually processed by a coiler.

[0003] The announcement number CN221657599U discloses a hot-rolled coil bending forming machine, including a support base, a hydraulic cylinder and a pressure roller. A rotating roller is suspended from the top of the support base, and a rotating motor is clamped to one end of the rotating roller. A hydraulic cylinder is set at the top of the support base, and an electromagnetic pressure plate is set at the bottom of the hydraulic cylinder. A pressure roller is clamped through one end of the rotating roller, and a lower mold is clamped to the top of the support base.

[0004] In the existing technology, when processing different plates, it is necessary to process them into different curvatures, so the lower mold and pressure roller need to be replaced. The existing device needs to be replaced simultaneously, which requires the operator to spend a long time to operate, making it time-consuming and labor-intensive. Therefore, this device provides a hot-rolled coil bending and forming machine. Utility Model Content

[0005] The purpose of this utility model is to provide a hot-rolled coil bending and forming machine to address the shortcomings of the existing technology and solve the aforementioned technical problems.

[0006] The present invention adopts the following technical solution: a hot-rolled coil bending forming machine includes a fixed frame, a first electric telescopic rod is fixedly installed on the top of the fixed frame, an installation frame is fixedly installed on the output end of the first electric telescopic rod, and a support box is fixedly installed on one side of the installation frame;

[0007] A first motor is fixedly installed on one side of the support box, a first drive shaft is fixedly installed at the output end of the first motor, and a turntable is fixedly installed on the outside of the first drive shaft.

[0008] Multiple rotating shafts are rotatably mounted on the inner side of the turntable, and connecting rollers are fixedly mounted on the outer side of the rotating shafts. Pressure rollers are provided on the outer side of the connecting rollers.

[0009] As a further improvement to the above solution, the bottom of the fixing frame is provided with a lower mold, an insertion block is fixedly installed at the bottom of the lower mold, a forming groove is opened at the top of the lower mold, an installation plate is fixedly installed on one side of the lower mold, and multiple threaded holes are opened on the front side of the installation plate and the fixing frame.

[0010] As a further improvement to the above solution, a second electric telescopic rod is fixedly installed on one side of the mounting bracket, a second motor is fixedly installed at the output end of the second electric telescopic rod, and a second drive shaft is fixedly installed at the output end of the second motor.

[0011] As a further improvement to the above solution, a connecting block is fixedly installed on the outer side of one end of the rotating shaft, and a control block is fixedly installed on the outer side of one end of the second drive shaft.

[0012] As a further improvement to the above solution, a control groove is provided on one side of the connecting block, and the control block fits into the control groove.

[0013] As a further improvement to the above solution, two insertion slots are provided on the front side of the fixing frame, and the insertion block fits into the insertion slots.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] 1. The turntable allows the corresponding pressure roller to move above the lower mold. The first electric telescopic rod is controlled to drive the mounting frame and pressure roller to descend, and the second electric telescopic rod is controlled to drive the control block to move. The control block can slide into the inside of the connecting block after sliding. The second motor can drive the second drive shaft, control block and connecting block to rotate. After the connecting block rotates, it can drive the rotating shaft, connecting roller and pressure roller to rotate. With the lower mold below, different plates can be processed, and the replacement of different pressure rollers is relatively convenient and quick.

[0016] 2. Insert different pressure rollers above the connecting roller. Since the pressure roller has a groove with the same shape as the connecting roller, the connecting roller and the pressure roller can be connected more tightly. When different plates need to be processed into different curvatures, the corresponding lower mold can be inserted into the upper part of the fixing frame through the insertion block. The fixing bolts are used to lock the mounting plate and the fixing frame in place, so that the lower mold will not loosen during the processing. Attached Figure Description
