Description

Technical Field

[0001] The invention relates to the technical field of wire drawing machines, in particular to a double-head wire drawing machine. Background Art

[0002] A wire drawing machine is a processing machine used to draw a metal wire with a larger diameter into a metal wire with a smaller diameter. During processing, when the copper wire passes through the eye die of the wire drawing machine, the inner wall of the eye die produces a large friction on the copper wire, causing the eye die to generate a certain amount of heat. Specifically, when the diameter of the copper wire increases, the heat generated by friction also changes in direct proportion, so it is necessary to add a device for cooling and lubricating the eye die on the basis of the existing wire drawing machine.

[0003] For example, the patent publication number is: CN 217121304 U, which discloses a high-speed wire drawing machine, specifically a turret-type high-speed wire drawing machine, which is composed of a chassis, a mold frame and a mold. A plurality of molds are installed in the wire drawing cavity of the chassis through the mold frame, and a wire drawing turret is installed on the chassis outside the mold frame. The circumference of the wire drawing turret is provided with a plurality of wheel grooves, and the wheel groove diameter decreases step by step from the outer end to the inner end of the wire drawing turret. During the operation of the wire drawing machine, the temperature can be reduced during the wire drawing process through a spray cooling mechanism.

[0004] Another example is the patent publication number: CN204470301U, which discloses an improved structure of a double-head center wire drawing machine, the structure of which is mainly based on a base, a gear box is installed at the rear end of the upper part of the base, and a wire drawing oil tank is arranged at the front end of the upper part of the base; an external motor drives a plurality of double-head wire drawing tower wheels in the wire drawing oil tank of the gear box through the input shaft of the gear box to rotate, and the wire drawing operation of the double wires is carried out simultaneously; an oil storage tank is arranged below the wire drawing oil tank, which is used as a temporary storage and circulation auxiliary for the rapid discharge of oil in the immersion wire drawing oil tank; and a structure of 6 groups of double-head wire drawing tower wheels is arranged in the wire drawing area; by setting the oil storage tank, the external water tank structure is abandoned, the structure is simplified, and when the wire is broken during the wire drawing production, the oil in the wire drawing oil tank is quickly discharged to the oil storage tank below, and the wire is re-inserted into the eye mold to resume production; the double-head wire drawing tower wheel is matched with the eye mold surface reduction rate and the double-head wire drawing machine structure design, and is used to improve the traditional single-head center wire drawing machine to improve production efficiency.

[0005] The above patents lubricate and cool the wires during the wire drawing process, whether through a spray cooling mechanism or an oil storage tank structure, but their structures are all fixed structures. Moreover, during the use of the spray cooling mechanism, if the coolant is improperly selected or overcooled, the cooling characteristics of the quenching medium or the tempering treatment should be mastered. If it is sprayed all the time, the pre-cooling time will be too long during the wire drawing process, and the toughness of the wire will decrease. If the structure of the wire drawing oil tank in the improved structure of the double-head center wire drawing machine is used for cooling and lubrication, its structure is simple, and it only lubricates the wire, and cannot cool the wire in all directions. The lubrication and heat dissipation performance is poor, which often leads to defects in the wire during the heat treatment process of the steel wire, thereby affecting the use effect of the steel wire.

[0006] Therefore, the present invention provides a double-head wire drawing machine with good heat dissipation and lubrication effects during the wire drawing process. Summary of the invention
