Efficient sealing multi-head wire drawing machine

Abstract

The invention discloses an efficient sealing multi-head wire drawing machine. The efficient sealing multi-head wire drawing machine comprises a transmission case, a wire drawing wheel axle, a wire drawing wheel and a wire drawing cavity; the wire drawing wheel axle penetrates through the transmission case wall and is rotatably arranged on the transmission case in a supporting mode through a bearing, a sealing spacer bush is arranged between the bearing and the wire drawing wheel and fixedly connected with the wire drawing wheel axle in a sealing mode, a sealing base is arranged between the bearing and the wire drawing wheel, and the sealing base is fixedly connected with the transmission case in a sealing mode; an engine oil sealing ring and a wire drawing oil sealing ring are arranged between the outer circle of the sealing spacer bush and an inner hole of the sealing base, the engine oil sealing ring is adjacent to the bearing, and the wire drawing oil sealing ring is adjacent to thewire drawing wheel; and a wire drawing oil drainage channel is arranged between the wire drawing oil sealing ring and the wire drawing wheel and communicates with the wire drawing cavity, and a leakage detection channel is arranged between the wire drawing oil sealing ring and the engine oil sealing ring and communicates with a viewer. According to the efficient sealing multi-head wire drawing machine, not only can sealing between the transmission case and the wire drawing cavity be guaranteed, but also a failed sealing device can be found in time, and the production efficiency of the wire drawing machine is guaranteed.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a cable drawing machine. Background technique [0002] The multi-head wire drawing machine can realize the drawing of multiple wires at one time. During the wire drawing process, each metal wire is wound in the corresponding wire drawing groove on the wire drawing wheel, and the wires to be drawn are drawn by several wire drawing wheels whose running speed increases sequentially from front to back. Under the limitation of the hole diameter of the wire drawing die between two adjacent wire drawing wheels, plastic deformation occurs and gradually thinned, so as to achieve the required thinner wire specification. The multi-head wire drawing machine has high production efficiency, but the workload is huge during the working process, and the lubrication requirements for the transmission mechanism in the transmission box are also quite high. Usually, a large flow rate of lubricating oil is used f...

Problems solved by technology

Under such working conditions, the seal between the wire drawing wheel shaft passing through the transmission box and the transmission box is particularly important. Once a seal fails among the numerous wire drawing wheel shaft sealing devices, the lubricating oil and the wire drawing oil will leak into each other. Participation will change the performance of the lubricating oil and / or wire drawing oil, resulting in a decrease in the lubrication performance of the transmission mechanism in the transmission box, poor heat dissipation of the wire in the wire drawing chamber, resulting in equipment damage or a decline in wire quality, which cannot guarantee normal production. However, the existing general-purpose sealing device cannot guarantee the required sealing effect, which seriously affects the normal operation and production efficiency of the wire drawing machine, and the existing wire drawing equipment lacks the necessary inspection means for the integrity of the sealing device, often in the sealing Failure can not be found in time, once a sealing device fails, it will inevitably lead to equipment accidents
