Description

TECHNICAL FIELD

[0001] The utility model relates to spring production equipment technical field, concretely relates to a spring color mark pad printing device. BACKGROUND

[0002] There is a color mark process in the production of automobile suspension springs. When the suspension spring production reaches the last process, the force of the spring needs to be measured, and different force values are marked with different colors of ink. The prior art uses a pad printing device to print color marks on the spring. For example, the utility model patent CN 213441668 U discloses a color mark pad printing device for springs. The cover body is provided with a through hole with a required cover pattern contour. The top of the inside of the cover body is provided with a liquid level sensor. When the liquid level sensor cannot detect the liquid level, it feeds back a signal to the controller. The controller controls the lifting mechanism to push the push plate upwards, so that the ink in the barrel rises to the detection range of the liquid level sensor in the through hole. The lifting mechanism stops rising to prevent ink from leaking to the surface of the cover body. The pad printing device can transport the gasket to the upper end of the through hole and the spring conveying device and make reciprocating motion to complete the contact of the gasket with the ink in the through hole or the extrusion of the spring to be printed. This device can reduce the amount of products with excess ink on the surface and increase the pass rate.
