Novel screw heading device and cold heading machining method thereof

Abstract

The invention discloses a novel screw heading device and a cold heading machining method thereof. The device comprises a device base frame, a left end forming assembly mounted on the device base frame, a material moving assembly mounted at a right end of the forming assembly, a feeding assembly which is mounted on the device base frame and located at a rear end of the material moving assembly, a main shaft assembly which is mounted on the device base frame and located at a right end of the material moving assembly, an adjusting assembly located between the main shaft assembly and the materialmoving assembly, a material pushing assembly located on a right side of the main shaft assembly, and a moving mechanism, wherein the forming assembly is provided with a first female die, a second female die and a third female die, the material moving assembly comprises a first fixing hole, a second fixing hole and a third fixing hole which are used for being matched with the first female die, thesecond female die and the third female die respectively, and the moving mechanism is used for moving a metal profile located at the position of the feeding assembly to the first fixing hole, moving the metal profile located in the first fixing hole to the second fixing hole in the working cycle and moving the metal profile located in the second fixing hole to the third fixing hole.

Description

technical field [0001] The invention relates to the technical field of cold heading equipment, in particular to a novel screw head device and a cold heading processing method thereof. Background technique [0002] In the current technology, the screw heading machine belongs to cold heading equipment, and its function is to punch one die and two punch products, mainly for forming the head of screw products. Its working principle is wire straightening, wire feeding, cutting, and feeding into the main die. , One punch for initial forging, two punch forming blank exit. It works in one go, and its production capacity can reach about 200 grains per minute, which is a relatively advanced product at present. Various metal materials can be upset and forged: general steel, carbon steel, stainless steel, copper, aluminum, alloy steel and other materials, with a wide range of uses. (Stainless steel, alloy steel and other materials can be heated to the suitable temperature with a heate...
