Description

Technical Field

[0001] The present application relates to the technical field of cold heading machine feeding, and in particular to a cold heading machine feeding oiling device. Background Art

[0002] Cold heading machine is a main machine for producing fasteners. At present, cold heading machines generally lack the replenishment of mechanical oil for cooling and lubrication during the upsetting and cutting processes. There is only a small amount of mechanical oil attached to the raw materials. Therefore, the cold heading machine is basically in an oil-deficient state during cutting and upsetting, which can easily cause the ball mold to be difficult to demold after upsetting, quality problems such as continuous balls, and wear of tools and molds, reducing their service life and increasing production costs.

[0003] The Chinese patent application number 201420100626.5 discloses a cold heading machine feed oiling device, which is installed below the feed device of the cold heading machine. Two feed pressing wheels pinch the raw material strip and feed it into the cutting die of the cold heading machine, so that the cutting mechanism and the upsetting mechanism of the cold heading machine cut and upset the raw material strip entering through the cutting die, respectively. The feed oiling device includes an oil pool containing oil arranged below the feed device, and the feed pressing wheel located below is immersed in the oil in the oil pool. The cold heading machine feed oiling device uses the feed pressing wheel to dip the oil in the oil pool and attach the oil to the surface and groove of the feed pressing wheel, so that the raw material strip in contact with the feed pressing wheel is also stained with oil, and finally the cutting knife and upsetting die in contact with the raw material strip are also stained with oil, solving the problem of oil shortage in the cold heading machine.

[0004] However, in the above patent, only the lower pressing wheel of the two feeding pressing wheels can apply oil to the raw material, and due to the gravity of the oil itself, the oil cannot reach the upper part of the raw material, and the overall oiling effect is poor. Therefore, a new technical solution is needed to solve the above problem. Utility Model Content
