Description

Technical Field

[0001] This utility model relates to the field of hardware straightening technology, and in particular to a hardware straightening device with adjustable spacing. Background Technology

[0002] Hardware straightening refers to the process of restoring deformed or bent hardware parts to their original shape. This is usually because the hardware parts have been deformed or twisted during production, transportation, or use. The purpose of straightening is to ensure that the shape and dimensions of the hardware parts meet design requirements and can be installed and used smoothly.

[0003] A straightening machine for processing metal casings of hardware parts disclosed in announcement number CN218798299U can effectively push the metal parts outward, assisting the metal parts to be flattened better. Furthermore, when the metal parts are flattened, the straightening rollers can be used to straighten the metal parts, thereby improving the flattening and straightening of the metal parts.

[0004] However, the straightening machine for processing metal casings of hardware parts has the following disadvantages: it is not convenient to return unqualified products for re-straightening in a timely manner. The traditional method is to collect unqualified products into a material box and then transfer them back to the production line for re-straightening, which is inefficient. Utility Model Content

Hardware parts that fail straightening are sent to the lower roller conveyor line 11 and sent back for repeated straightening, which improves the work efficiency.

[0028] The adjustment mechanism 4 includes a threaded sleeve 401 and an adjusting screw 402. The threaded sleeve 401 is fixedly installed at the output end of the A servo motor 3, and the adjusting screw 402 is threadedly connected to the inside of the threaded sleeve 401.

[0029] By adjusting the mechanism 4, when the servo motor 3 is powered on, it drives the threaded sleeve 401 to rotate, which causes the adjusting screw 402 to drive the lifting frame 5 to rise and fall, adjusting the distance between it and the upper roller conveyor line 1.

[0030] The transmission mechanism 8 includes an A-wheel 801, a transmission belt 802, and a B-wheel 803. The A-wheel 801 is fixedly mounted on the output end of the B servo motor 7. The transmission belt 802 is sleeved on the surface of the A-wheel 801. The B-wheel 803 is rotatably mounted inside the transmission belt 802.

[0031] Through the transmission mechanism 8, the B servo motor 7 drives the A wheel 801 to rotate, which causes the transmission belt 802 to drive the B wheel 803 to rotate, thereby driving the two sets of straightening rollers 9 to rotate and straighten the hardware parts.

[0032] Four sets of support columns 14 are provided between the upper roller conveyor line 1 and the lower roller conveyor line 11, and the four sets of support columns 14 are distributed in a rectangular array.

[0033] The support column 14 serves to support the upper roller conveyor line 1.

[0037] The mounting plate 6 facilitates the fixing of the B servo motor 7.

[0038] Support legs are fixedly installed around the bottom of the lower roller conveyor line 11, and the four sets of support legs are distributed in a rectangular array.

[0039] The support legs serve to support the lower roller conveyor line 11.

[0040] In this invention, the working steps of the device are as follows:

[0041] First step: After the servo motor 3 is powered on, it drives the threaded sleeve 401 to rotate, which causes the adjusting screw 402 to drive the lifting frame 5 to rise and fall, adjusting the distance between it and the upper roller conveyor line 1.

[0042] The second step: B ​​servo motor 7 drives A roller 801 to rotate, which causes the transmission belt 802 to drive B roller 803 to rotate, which in turn drives two sets of straightening rollers 9 to rotate and straighten the hardware parts. The distance between the straightening rollers 9 and the upper roller conveyor line 1 can be adjusted to adapt to hardware parts of different thicknesses.

[0043] The third step: The upper roller conveyor line 1 is used to transport hardware parts. After straightening is completed, personnel conduct quality inspection at the quality inspection table 10. Hardware parts that pass straightening will enter the next process, while hardware parts that fail straightening will be sent to the lower roller conveyor line 11 for repeated straightening, which improves work efficiency.
