Description

A shearing machine for processing guardrail accessories

Technical Field

The utility model relates to the technical field of shearing machines, and in particular to a shearing machine for processing guardrail accessories.

Background Art

Guardrail accessories refer to the hardware decorations that are necessary for the installation of various guardrails. Their main functions are fixing, connecting and decorating. They are mainly suitable for balcony guardrails, stair guardrails, road traffic guardrails, fences, fences, shutters and anti-theft windows. In the processing of guardrail accessories, they need to be sheared by shearing machines. The shearing machines can use the moving upper blade and the fixed lower blade, and adopt reasonable blade gaps to apply shearing force to guardrail accessories of various thicknesses, so that the guardrail accessories can be broken and separated according to the required size. However, the current shearing machines have poor limiting effect on the guardrail accessories during the shearing process, which easily causes the guardrail accessories to warp during the shearing process, which will cause uneven burrs at the sheared parts of the guardrail accessories, which will reduce the shearing quality of the guardrail accessories;

After searching, the utility model with patent publication number CN216575774U discloses a shearing mechanism for a shearing machine, which clamps and fixes the plate through a clamping mechanism to improve the stability of shearing; the cooperation of the guide sleeve and the guide rod can avoid the deviation of the knife seat and improve the stability of the upper blade during the shearing process; the plate is pressed and fixed during the shearing process through the setting of the first spring and the pressure plate to avoid the edge of the plate from warping during the shearing process. Although it is convenient to limit and shear the plate, after shearing a certain part of the plate, it is necessary to release the limit of the plate, adjust the shearing position, and then limit the plate again before shearing. The cutting time is long, and the cutting efficiency of plates such as guardrail accessories is low.
