Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-speed feeders, in particular to a multi-guide column oil circuit structure. Background Art
[0002] A feeder is a machine that uses the force of mechanical motion to apply force to materials, moving and transporting them. It is an indispensable piece of equipment for both light and heavy industries, and the clamp in a feeder is a key component that primarily grips and delivers the material. In particular, in the field of metal stamping, feeders can feed strips or sheets of material into the stamping die, adjusting the size of the die.
[0003] In actual material transportation, there is a mobile clamping block at the bottom of the mobile clamp that can move with the mobile clamp. The bottom of the mobile clamping block is connected to the guide slider through a plug-in column and can move up and down. Since the guide slider and the mobile clamping block are in a state of high-speed back and forth motion for a long time, and the mobile clamping block moves up and down alternately during the back and forth movement, it is easy to cause serious wear of the plug-in hole in the guide slider over a long period of time. Our company has developed a feeder with a multi-guide column structure to form a horizontal limit structure with multiple guide columns, which can effectively distribute the lateral offset force of the plug-in column to both sides of the socket hole and the guide column, and reduce the friction deformation between the plug-in column and the plug-in hole from the force-bearing structure.
[0004] Lubricant is required between the socket hole and the guide column to lubricate both. However, since the movable clamp and the guide slider maintain a high degree of rotation for a long time during operation, it is difficult to provide an effective lubrication solution. Therefore, in view of these current situations, it is urgent to develop a multi-guide column oil circuit structure to meet the needs of actual use. Utility Model Content
