Spring press

Abstract

The invention discloses a spring press. A rack is provided with a doubling-up press die, a striking block support, a speed reduction motor, an eccentric shaft, a lever, a connection rod and a gap bridge support, wherein a firing pin is positioned in a groove of the doubling-up press die, a striking block extends from a through hole of the striking block support, a cam is arranged in the middle of the eccentric shaft, and a belt wheel is arranged at the input end of the eccentric shaft, the speed reduction motor is connected with the belt wheel by a belt, two ends of the connection rod are movably connected with the eccentric shaft and a gap bridge shaft respectively; one end of the gap shaft, close to the connection rod, is a U-shaped fork, the other end of the gap bridge shaft extends out from a through hole of the gap bridge support, one end of the lever is meshed with the cam by a roller, and the other end of the lever is positioned on an upper press plate of the doubling-up press die. After the structure is adopted, the upper press plate of the doubling-up press die is tightly pressed by the lever, the manual press is avoided, the labor intensity is reduced, a traction electromagnet is replaced by the eccentric shaft, the connection rod and the gap bridge shaft, so that the maintaining cost is lowered, the degree of automation of a doubling-up machine is improved, and the operational difficulty of workers is reduced.

Description

technical field [0001] The invention relates to a spring press. Background technique [0002] In the traditional spring press, the machine frame is equipped with a ring-joining die, a bumper support, a traction electromagnet and a foot switch. The lower pressing plates are connected together, the open end is provided with an opening spring, the striker is located in the groove of the parallel die, the striker protrudes from the through hole of the striker support, and a return spring is arranged in the striker support, and the striker It is located on the same axis as the firing pin. During production, one hand puts one end of the spring into the paralleling die, and the other hand presses the upper platen of the paralleling die. At the same time, use the foot to activate the foot switch to pull the electromagnetic The iron is energized and sucked, so that the bump hits the firing pin, and the firing pin presses the spring to realize the parallel coil. Such a winding machi...

AI Technical Summary

Problems solved by technology

Such a winding machine has a high frequency of traction electromagnets, the coil is easy to burn out, and the maintenance cost is high. In addition, workers need to use both hands and feet when operating, which is labor-intensive, low in production efficiency, and requires high operating skills.
