Description

Technical Field

[0001] The utility model relates to the field of bending machine guide rails, in particular to a full-servo bending machine needle roller guide rail structure. Background Art

[0002] A bending machine is a metal processing equipment, which is mainly used to bend metal plates, bars, etc. to form the required bending angle and shape. During the operation of the bending machine, the rotating needle roller replaces the bending machine to contact the processing material. The rotating needle roller can directly avoid the friction caused by pressing and cause damage to the equipment and materials. When the needle roller is installed inside the bending machine, it needs to be clamped and fixed at both ends of the needle roller through the guide rail structure;

[0003] A Chinese patent with publication number CN218873364U discloses a bending machine needle roller guide device, including a guide rail seat, a limiting device and two pairs of linkage devices. A "V"-shaped bending groove is opened on the top of the guide rail seat, and placement grooves are opened on the inner walls on both sides of the bending groove near the top. The threaded frame is rotated by the provided limiting device. Under the action of the threaded frame, the movable plate gradually moves toward the guide rail seat, thereby limiting the two rows of needle rollers. Compared with the traditional method of limiting the two rows of needle rollers by two baffles, the device is more convenient to operate and saves the time of the staff.

[0004] During the installation of the bending machine needle roller guide device of the above-mentioned patent, the rotation direction of the guide rod is fixed, so that the bending machine needle roller guide cannot be used in a narrow environment during the installation process. The protruding structure corresponding to the threaded frame needs to be rotated at a fixed angle, which is not convenient for users to use and is not convenient for the installation and disassembly of the internal needle roller.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a full-servo bending machine needle guide structure, including a guide rail seat, placement grooves are provided on both sides of the upper end of the guide rail seat, and rollers are provided inside the two placement grooves, and a first assembly block is provided at one end of the two placement grooves, and a connecting plate is provided at the other end of the guide rail seat, and third assembly blocks are provided on both sides of the front and rear ends of the connecting plate facing the end of the needle roller, one side of one of the third assembly blocks is provided with a threaded rod, one end of the threaded rod is embedded in the connecting plate and connected to the rotating slot inside the connecting plate, and a third sector gear is welded to one end of the threaded rod inside the connecting plate.

[0007] Preferably, a first sector gear is arranged at the upper end of the outside of the third sector gear, a second sector gear is arranged at one side of the outside of the third sector gear, and the second sector gear, the third sector gear and the first sector gear are meshed and connected in sequence.

[0008] Preferably, a second transmission block is welded to one end of the first sector gear, and a first transmission block is welded to one end of the second sector gear.

[0009] Preferably, one end of the second sector gear and the first sector gear are both connected to the internal rotation slot of the connecting plate.

[0010] Preferably, an active cavity is provided at one end of the third sector gear, and the active cavity passes through the connecting plate and is embedded in the outside of the third sector gear.

[0011] Preferably, another section of the guide rail seat is recessed toward the threaded rod to form a first mounting hole, and the interior of the first mounting hole is matched with the external thread of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model can fix the connecting plate by rotating the threaded rod in the first mounting hole, and a third sector gear for transmission is arranged at one end of the threaded rod, and the first sector gear and the second sector gear are arranged around the outside of the third sector gear. Firstly, the rotation of the second transmission block position can drive the threaded rod to rotate through the first sector gear, and secondly, the rotation of the first transmission block position can also drive the threaded rod to rotate through the second sector gear.
