Description
Technical Field
The utility model relates to the field of metal extrusion forming tools, in particular to a vehicle oil plug cold forming die assembly.
Background
The cold extrusion molding is a mainstream means for manufacturing fasteners nowadays due to high material utilization rate, high productivity and good product size consistency. The cold extrusion forming process (cold heading process) mainly uses a multi-station cold heading machine to cold-heading round rod and wire materials into various parts, the wire materials are provided in a coiled form by a long wire material with the weight of ton, and after the wire materials are introduced into the cold heading machine, the round rod and wire materials with the length required by the product are cut off by an internal material cutting mechanism of the equipment in a cutting and material cutting mode to carry out subsequent cold heading processing. The material cutting mechanism has a certain choice on influencing related parameters of the quality of a sheared and cut material section in order to keep up with the production rhythm of cold heading and stabilize feeding, so that the end surface collapse and unevenness of the cold heading material cutting cannot be avoided, a vehicle oil blocking product is a countersunk head bolt part, a sealing effect is required besides a screwing effect through threads, and the requirements on related sizes and form and position tolerances of conical surfaces of the parts are high. In general, in the conventional process, a semi-finished product is processed to the required precision requirement by a machining method and then is extruded into an inner hexagon, so that the material utilization rate is low, the stability of the machining performance is poor, the machining time of a single machine is long, and the efficiency is low. On the other hand, the formation of the conical surface of the oil plug is necessarily performed before the formation of the inner hexagon during the cold heading process, if the inner hexagon is formed first and then the inner hexagon is formed, the inner hexagon deforms to cause the dimensional requirement to be not met, and the formed conical surface is tilted to some extent during the formation of the inner hexagon, so that the precision requirement of the oil plug product cannot be met.
