One-shot molding production equipment for pushpins and production process for pushpins

Abstract

The invention provides a one-time pushpin forming production equipment and a pushpin production process, including a workbench, a wire straightening mechanism and a column are arranged on the workbench, a through hole for the wire to pass through is arranged on the column, and a fixing seat is arranged on the column The fixed seat is rotatably connected with a bearing that is consistent with the axis of the through hole. One end of the bearing is provided with a gear, and the other end is provided with a steel wire guide column. The steel wire guide column is provided with a vertical downward incision. For the first cutting block and the second cutting block for cutting the steel wire, the first cutting block is connected with a second cylinder, the top of the column is provided with a vertically downward first cylinder, and the first cylinder is connected with a production plate, The side and bottom surface of the production plate facing the column are slotted. One side of the production plate is provided with a vertical rack that cooperates with the gear. For a pin cap plate, the invention provides a low-cost and reliable one-step forming production equipment for push pins and a production process for the push pins.

Description

technical field [0001] The invention relates to the technical field of thumbtack production devices, in particular to a pushpin one-time forming production equipment and a pushpin production process. Background technique [0002] In the existing drawing pin processing technology, the nail cap and nail pin are processed separately first, and then the nail cap and nail pin are combined by special equipment. There are too many mechanical processing steps, more equipment is required, and a large energy space is occupied. Because the nail pin and the nail cap are processed in combination, whether it is a welding combination or a stamping combination, if the quality control is not uniform during production, the connection force between the nail cap and the nail pin will not be firm, and it is easy to appear that the nail cap and the nail when prying out the thumbtack during use. Needle detachment problem. In view of the above problems, this case was born. Contents of the invent...
