band-it grippers, German band-it models, band-it pricing

band-it grippers are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grasp products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grasping products with rough surfaces, and polyurethane suction cups are highly durable. Additionally, in actual production, if oil resistance is required for the suction cups, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing them. Typically, to avoid scratching the product surface, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

band-it gripper applications

Whether it is a simple hydraulic fixture or a complex integrated production line, the design process for hydraulic fixtures remains the same, proceeding in the following order: formulation of the overall scheme, selection of hydraulic cylinder types and specifications, selection of control valves, design of mechanical components, selection of pump station accessories, and system connection. Hydraulic fixtures provide powerful clamping and positioning forces for various machining processes. Yun Dongli hydraulic cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements provide accurate positioning, swing cylinders and lever cylinders provide clamping force on products, and support cylinders prevent deformation during product machining. From simple fixturing to robot-assisted machining centers, hydraulic cylinders provide clamping and support forces to enhance production efficiency.

band-it gripper structure

The mechanical gripper-type end effectors applied in loading and unloading industrial robots are mostly two-finger grippers. If classified by finger motion, they can be divided into translational and rotary types. If classified by mechanical clamping method, they can be divided into external clamping and internal expansion types. If classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. When the end effector clamps a workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is fully released during movement, dwelling, and loading. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the given tolerance zone.

band-it gripper applications

1) Consistently ensures machining accuracy of workpieces: When clamping workpieces with fixtures, the positional accuracy of the workpiece relative to the tool and machine tool is guaranteed by the fixture, unaffected by the worker's skill level, making the machining accuracy of a batch of workpieces consistent. 2) Reduces auxiliary time and improves labor productivity: Using fixtures makes workpiece clamping convenient and fast; workpieces do not require scribing and alignment, significantly reducing auxiliary time; after clamping in the fixture, the rigidity of the workpiece is improved, allowing for increased cutting parameters; fixtures capable of clamping multiple workpieces or at multiple stations can be used, along with high-efficiency clamping mechanisms, further improving labor productivity. 3) Expands the usage range of machine tools, achieving multi-functionality: Based on the forming motion of the machining machine tool, attaching different types of fixtures can expand the original process range of the machine tool. For example, installing boring jigs on the carriage of a lathe or the table of a radial drilling machine allows for boring operations on box-type parts. 4) Ensures machining accuracy: Installation using fixtures accurately determines the mutual position between the workpiece, machine tool, and cutter. The positional accuracy of the workpiece is guaranteed by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Improves productivity and reduces costs: Clamping workpieces with fixtures allows for rapid positioning and clamping without alignment, significantly reducing auxiliary time; clamping workpieces with fixtures improves workpiece rigidity, allowing for increased cutting parameters; fixtures for clamping multiple workpieces or at multiple stations can be used, along with high-efficiency clamping mechanisms, all of which help improve labor productivity. Additionally, using fixtures stabilizes product quality, reduces scrap rates, allows for the assignment of lower-skilled workers, and significantly lowers production costs. 6) Expands the process range of machine tools: Using special fixtures can change the original purpose of the machine tool and expand its usage range, achieving multi-functionality. For example, after installing boring jig fixtures on lathes or radial drilling machines, boring operations can be performed on hole systems of box parts; special fixtures can also convert lathes for broaching use, fully leveraging the capabilities of general-purpose machine tools. 7) Reduces workers' labor intensity: Clamping workpieces with fixtures is convenient and fast; when using pneumatic, hydraulic, or other clamping devices, workers' labor intensity can be reduced.
