Cut-off machine for plastic row pins

Abstract

The invention discloses a cut-off machine for plastic row pins. The cut-off machine for plastic row pins consists of a driving device, a contact pin supporting seat, a locating device, a sliding device, a right lateral board, a cover board, a needle dial, a machine cover, a bottom board and a pneumatic foot pedal switch. The driving device is adopted for performing two functions: the pass of force is realized by driving a specially-made rotary block by a cylinder or manually driving a pressing shaft; the locating device is moved by the tilted surface between the specially-made rotary block and a limiting sleeve; the locating part moves back for flexibly locating the plastic row pins, so that the blades and plastic row contact pins are unlikely to be damaged; the plastic row pins are symmetrically cut by blades, so that no powder is generated in the cutting process; slots on the plastic row contact pins are aligned automatically when the contact pins are cut laterally to guarantee the accurate cutting without damaging the pins; and the supporting seats of the pins are composed of three parts with different shapes to form a convex shape to be installed tightly close to two cutters, so that double pins can be cut without being left in the process of cutting a single pin.

Description

technical field [0001] The invention relates to a plastic row pin cutting device, in particular to a plastic row pin cutting machine used for jumping wires on printed circuit boards in the electronics, computer and communication industries. Background technique [0002] There are two ways to shorten the plastic row pins, sawing with a saw blade and cutting with a blade. The technology of the sawing method is relatively mature, but there are several deficiencies. First, dust is generated, which pollutes the environment; second, the grinding wheel or saw blade is easy to wear, and the processing cost is high; third, the processing efficiency is low. Although the blade cutting method does not have the above shortcomings, there are three problems that have not been resolved. The problem of accurate positioning of the plastic row pins and the convenience of adjusting the number of pins; how to cut quickly and accurately with a high yield; When inserting pins, the problem cannot ...

Problems solved by technology

The technology of the sawing method is relatively mature, but there are several deficiencies. First, dust is generated, which pollutes the environment; second, the grinding wheel or saw blade is easy to wear, and the processing cost is high; third, the processing efficiency is low.

Although the blade cutting method does not have the above shortcomings, there are three problems that have not been resolved. The problem of accurate positioning of the plastic row pins and the convenience of adjusting the number of pins; how to cut quickly and accurately with a high yield; When inserting pins, there is a problem that the last stitch and the penultimate stitch cannot be cut off
