Description

Technical Field

[0001] The invention relates to the technical field of steel plate shearing, and in particular to a steel plate shearing device for ventilation slots of bag dust collectors. Background Art

[0002] The ventilation slot in the bag dust collector refers to the part used to introduce the dust-containing gas into the bag dust collector for filtering treatment. It is also called the gas inlet or air inlet. The ventilation slot plays a key role in the entire bag dust collector system. It introduces the dust-containing gas generated in industrial production into the dust collector, intercepts the dust particles through the filtering action of the filter bag, and then discharges the purified air.

[0003] The ventilation slots of bag dust collectors are usually rectangular and made of steel plates. They are processed through processes such as steel plate cutting, bending, welding and grinding. Among them, steel plate cutting is one of the most important processing processes for the ventilation slots of bag dust collectors.

[0004] The most commonly used shearing equipment in the existing bag filter ventilation slots is a conventional shearing machine, which uses the docking of the moving upper blade and the fixed lower blade to break and separate the plate according to the required size. This equipment generally only has the shearing function. For steel plates that need to be sheared in different sizes, auxiliary conveying equipment is also required to complete the entire process. This type of auxiliary conveying equipment also only has the function of conveying. However, the shearing of steel plates needs to ensure uniformity. At this time, it is necessary to rely on manual judgment of the lifting angle of the crane to correct the angle of the steel plate. The overall process equipment accounts for a large proportion, and each step needs to be controlled step by step, which is not convenient to use. At the same time, the lower blade of the shearing machine is fixed, which will cause a large hard collision with the lower blade due to inertia after each shearing. If this continues for a long time, it will cause wear and tear on the upper and lower blades, shortening the service life of the upper and lower blades. Summary of the invention
