Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing devices, in particular to a shearing support mechanism for slender cylindrical hardware. Background Art

[0002] The main function of slender cylindrical hardware is to support and fix other parts and provide the necessary mechanical strength and stability. Slender cylindrical hardware is characterized by being slender and cylindrical, usually made of metal materials such as steel, aluminum or copper, etc. Its length is much larger than its diameter, and it usually has high precision and smooth surface quality so that it can fit closely with other parts. In machinery and tool manufacturing, slender cylindrical hardware is widely used. For example, it can be used as bearings, bushings, piston rods, gas cylinders, fasteners, support rods, etc.

[0003] In the existing hardware shearing process, most of the operators use tools such as hand saws to shear the hardware. This method has the disadvantages of low shearing efficiency and poor installation matching due to uneven shearing, and is less practical. Chinese patent CN210523941U discloses a hardware shearing device. The operator places the hardware on the top of the workbench, measures the required cutting length, slides the sliding baffle, makes the left end of the sliding baffle contact with the right end of the workpiece to be processed, rotates the bolt to fix the sliding baffle, then starts the cylinder, the bottom end of the cylinder outputs power, the piston moves down, the bottom end of the cutting blade contacts with the top of the hardware, and then starts the motor, the right end of the motor outputs power, drives the cutting blade to rotate at high speed through the transmission and the transmission shaft, and the cutting blade shears the hardware. The sheared hardware falls through the through hole to the collection device at the bottom for collection. By setting the above device, the operator can use the hand saw to shear the hardware instead of the operator, so that the shearing section is flat, the work efficiency is improved, and the hardware can be collected, reducing the labor pressure of the operator and improving the practicality.

[0004] The above technical solution also has the following defects: the hardware shearing device mainly uses a sliding baffle to limit the position of the hardware, but lacks a structure to fix and support the hardware, so the hardware will still shake violently during the shearing process. Since slender cylindrical hardware is prone to rolling when placed, the hardware shearing device cannot meet the shearing requirements for slender cylindrical hardware. Summary of the invention
