Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing equipment, and more specifically relates to a bar end face chamfering and shaping device with size calibration. Background Art

[0002] At present, in the production of metal bars, in order to improve efficiency, a continuous production line is generally used, that is, the wire is straightened, cut, ground, heat treated (surface treated), polished, and end-face processed to finally form a qualified bar. In the end-face processing, in addition to shaping the end face of the bar, it is also necessary to chamfer the end face of the bar.

[0003] In the current chamfering shaping devices, most of them convey the bar to a conveyor chain with multiple V-blocks. When the bar is conveyed to the processing position by the conveyor chain, the bar on the V-block is clamped, and then the rotating tool approaches the end face of the bar to shape and chamfer the end face. In general, processing equipment is set on both sides of the conveyor chain, that is, the two end faces of the bar are processed at the same time. Therefore, the bar is usually conveyed to the V-block of the conveyor chain from the side (such as Figure 2 shown).

[0004] Currently, sufficient size is reserved when cutting bars, so that there can be a large margin for end face shaping during chamfering. Therefore, as long as the position of the bar falling on the V-block is roughly accurate, the bar can be directly pressed and processed, which is highly efficient but wastes the bar material. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a bar end face chamfering and shaping device with size calibration, which reduces the processing allowance in the bar cutting stage and saves bar material.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bar end chamfering and shaping device, comprising a stacking rack and a conveying chain, an inclined material guide plate is arranged between the stacking rack and the conveying chain, push plates are arranged on both sides of the material guide plate, a driving device is connected to the push plates, the two push plates can move closer to or away from each other, first length sensors are arranged at both ends of the push plates, a first material stop plate is arranged at the end of the material guide plate close to the conveying chain, and a driving device is connected to the first material stop plate.

[0007] Furthermore, a pressing plate is arranged above the push plate, an elastic friction pad is arranged on the side of the pressing plate facing the material guide plate, and a driving device is connected to the pressing plate.

[0008] Furthermore, the push plate is slidably connected to the material guide plate, and a movement sensor is arranged between the push plate and the material guide plate.

[0009] Furthermore, a second length sensor is arranged above the stacking rack.

[0010] Furthermore, a second material baffle plate is provided on one end of the material stacking rack close to the material guide plate, and a driving device is connected to the second material baffle plate.

[0011] Compared with the prior art, the beneficial effect of the utility model is that after the bar rolls down from the stacking rack onto the guide plate, through multiple inspections and adjustments, the two ends of the bar can be more accurately aligned with the processing position, thus reducing the processing allowance of the bar during the cutting stage and saving bar material.
