Description

Technical Field

[0001] The utility model relates to the field of steel bar processing equipment, in particular to a steel bar guiding and pulling device. Background Art

[0002] In the production of steel bar processing, the steel bar is often moved step by step to the next processing station for cutting, bending or other processing steps. In this process, the relative position of the stepping clamping and traction device and the processing device on the next station will change during the stepping process.

[0003] At present, fixed guide tubes or traction wheels are usually used for traction feeding. The maximum distance between the end of the guide tube or traction wheel and the next station needs to be no less than the step distance of the steel bar each time, otherwise a collision will occur. This results in the steel bar not being guided to the next station for at least the length of the step distance. There is a risk of the steel bar being bent during this distance. If the steel bar is severely bent, the lack of full-length guidance may also make it impossible for the steel bar to enter the device of the next station smoothly.

[0004] The Chinese patent document with publication number CN220005770U discloses a steel bar straightening machine, in which a clamping mechanism reciprocates to feed the steel bar to be straightened, and a guide assembly includes a guide seat, on which a guide tube or a guide hole is provided. In this technical solution, the guide tube or the guide hole is used to guide the steel bar fed in a step-by-step manner, and there is the above-mentioned problem of no guide section between the guide tube or the guide hole and the clamping mechanism.

[0030] The devices at adjacent workstations may be processing devices for cutting, bending or other processing steps.

[0031] Furthermore, in this embodiment, the first guide tube 31 is an outer tube, and the second guide tube 32 is an inner tube. The inner tube has a smaller diameter, and the inner tube is connected to the device of the adjacent station, which facilitates the smooth entry of the steel bar 6 into the device of the adjacent station and improves the guiding effect. Of course, in other embodiments, the first guide tube 31 can also be an inner tube, and correspondingly, the second guide tube 32 is an outer tube.

[0032] Furthermore, in this embodiment, two guide mechanisms 3 are provided and are respectively located on both sides of the clamping mechanism 2.
