Machine grinding working principle:
Workpieces enter the circular track via the left-side loading mechanism and are driven by the conveyor to pass through the grinding stations sequentially. After completion, they are unloaded from the right side, achieving continuous production. The four grinding heads are divided into two unit groups, with each group corresponding to the simultaneous processing of two beer cans. The grinding hea ds use high-speed rotating grinding wheels to perform rough grindi ng (deburring and removing oxide layers) and fine grinding (improv ing surface finish) on the can surface. The beer cans are fixed by special clamps during the conveying process,and the grinding hea ds can be automatically adjusted according to preset parameters (such as pressure and speed)to ensure uniform grinding.
Machine tool component parameters:
Base and frame structure:
The main frame is constructed from high-quality Q235 square steel tubing, ensuring high rigidity and resistance to deformation. The l oad-bearing platform is covered with 10mm thick anti-slip steel pla tes and features localized reinforcing ribs. The machine tool frame feet are equipped with adjustable anchor bolts to accommodate i nstallation on uneven ground.
Workpiece grinding system (four grinding heads):
The grinding unit is divided into two grinding sections (rough grind ing and fine grinding), each equipped with two grinding heads. Ea ch set of grinding heads is driven by an independent motor to en sure balanced load. The grinding head end is equipped with a do uble pressure wheel device to apply constant pressure to the work piece surface, ensuring consistent grinding. The grinding head is eq uipped with a forward and backward slide table. The transverse st roke of the grinding head is 0-150mm, consisting of a cylinder an d a lead screw. The lead screw is used for cylinder stroke limit an d can be manually adjusted to a specified position according to th e can diameter and grinding wheel wear.
Workpiece conveying system:
It adopts double-row chain drive, which has a strong load-bearing capacity; each station is equipped with a dedicated rotating fixture, and the fixture part is made of wear-resistant nylon material to avoid scratching the workpiece; the fixture moves in a circular motion with the chain and has a self-locking function to prevent it from loosening midway; the conveying speed is adjustable and controlled by a frequency converter, matching the workpiece conveying speed to the grinding time (1-5m/min).
Workpiece rotating components (four sets of rotating component s):
Each grinding head's grinding area is equipped with a workpiece r otation component, consisting of two sets of rollers and a workpie ce rotation motor. Each grinding area selection component is electr ically movable, primarily for workpiece conveying and switching bet ween different pipe diameters. The rotation component has a strok e of 200mm. The workpiece rotation speed can be set on the tou chscreen and optimized according to the can type and abrasive. T he startup logic is linked to the grinding head: rotation and grindi ng only start when the workpiece is in place and clamped; it auto matically stops after grinding is complete, reducing idling wear.
Machine dust prevention and observation system:
The fully enclosed grinding area cover is made of welded steel pla tes, effectively isolating dust from spreading; a tempered glass obs ervation window is provided on the front for real-time monitoring of the grinding process; maintenance doors are reserved on both s ides of the cover, and a top exhaust port (Φ150mm flange) conne cts to a central dust collection system (vacuum cleaner optional).
Electrical control components:
The machine uses a PLC programming control cabinet, consisting o f a frequency converter, PLC, touch screen, and other low-voltage electrical components, and achieves automatic grinding through PLC programming. The machine tool consists of a power cabinet and an operating cabinet. An emergency stop button, a red mushroom- shaped button, is additionally located at both the loading and unl oading ends.
