Drawing pin one-time forming production equipment and drawing pin production process

Abstract

The invention provides drawing pin one-time forming production equipment and a drawing pin production process. The equipment comprises a worktable, a steel wire straightening mechanism and a stand column are mounted on the worktable, a through hole allowing a steel wire to penetrate through is formed in the stand column, a fixing base is arranged on the stand column, a bearing consistent with theaxis of the through hole is rotatably connected to the fixed base, a gear is arranged at one end of the bearing, the other end of the bearing is provided with a steel wire guide column, a vertical downward cut opening is formed in the steel wire guide column, a first cutting pressing block and a second cutting pressing block used for cutting off the steel wire are arranged on the two sides of thefixing base, the first cutting pressing block is connected with a second aircylinder, the top of the stand column is provided with a vertical downward first air cylinder, the first air cylinder is connected with a making plate, the side, facing the stand column, and the bottom face of the making plate are provided with grooves, a vertical rack matched with the gear is arranged on one side in the making plate, and the other side in the making plate is provided with a pressing needle cap plate with one end abutting against the circumference side wall of the steel wire guide column. The drawing pin one-time forming production equipment and the drawing pin production process are low in cost and reliable.

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...
