用于直进式连续拉丝机的内冷式大盘  Internally cooled large format for straight-through continuous wire drawing machines
技术领域 Technical field
[0001] 本发明涉及一种金属线材拉拔设备中应用的大盘， 特别是一种用 于直进式连续拉丝机的内冷式大盘。 背景技术  [0001] The present invention relates to a large disk for use in a metal wire drawing apparatus, and more particularly to an inner cooling type large disk for a straight-through continuous wire drawing machine. Background technique
[0002] 目前， 用于直进式连续拉丝机的内冷式大盘的结构呈圆盘状， 其 中心部位为带有中心孔的轮毂， 轮毂通过轮辐连接有轮缘， 在轮缘的两侧 边有挡边。 通过中心孔将大盘安装在转动轴上， 转动轴通过减速机构与电 机的输出轴相接。  [0002] At present, the structure of the inner-cooling large-sized disk for the straight-through continuous wire drawing machine has a disk shape, and the center portion thereof is a hub with a center hole, and the wheel hub is connected with a rim through the spokes, on both sides of the rim There are ribs on the side. The large plate is mounted on the rotating shaft through the center hole, and the rotating shaft is connected to the output shaft of the motor through a speed reducing mechanism.
[0003] 上述装置为多组且连续设置， 在每组的大盘前部均设有拉拔模装 置， 金属线材穿过拉拔模并绕在大盘的轮缘外侧且经压线机构排线， 工作 时电机带动大盘转动， 线材与大盘之间的摩擦拉力将线材自拉拔模拉出， 在拉出过程中完成了线材的拉拔。  [0003] The above-mentioned devices are arranged in multiple groups and continuously arranged, and a drawing die device is arranged at the front part of each group of large disks, and the metal wire passes through the drawing die and is wound around the rim of the large disk and is lined by the pressing mechanism. During operation, the motor drives the large disk to rotate, and the frictional pulling force between the wire and the large disk pulls the wire from the drawing die, and the wire is drawn during the pulling process.
[0004] 金属线材在拉拔时， 由于金属变形及线材与拉丝模之间的强烈磨 擦使线材发热， 线材的热量将使拉拔润滑剂失效， 温度过高时还将严重影 响线材的品质。 特别是在高速和连续直进式拉拔过程中. 线材的温升更为 严重， 必须对其进行冷却。  [0004] When the metal wire is drawn, the wire is heated due to metal deformation and strong friction between the wire and the wire drawing die, and the heat of the wire will invalidate the drawing lubricant, and the temperature will be too high to seriously affect the quality of the wire. Especially in high-speed and continuous straight-through drawing processes. The temperature rise of the wire is more serious and must be cooled.
[0005] 现有的连续直进式拉丝机冷却线材的方法， 主要是冷却拉拔线材 的拉丝模和缠绕线材的大盘。 大盘的冷却方法又可分为直接水冷法和间接 水冷法两种。 前者是将缠绕线材的大盘直接在水箱中转动， 虽然具有较好 的冷却效果， 但当线材进入下一道拉丝模之前， 必须采用较大功率的压缩 空气吹干机， 在极短时间内吹干线材表面的水渍， 造成设备结构复杂， 耗 能多， 且吹干不彻底， 少量水份带入下道次拉拔的润滑槽中， 影响润滑效 果； 后者的传统冷却方法， 是把冷却水喷到大盘轮缘的内壁上， 吸收大盘 轮缘的热量， 间接冷却线材， 但由于大盘是转动部件， 喷洒的冷却水不是 处于封闭状态， 必然有一定量冷却水流到大盘轮缘的外侧使线材润湿， 仍 需采用大功率压缩空气机吹干， 同样存在上述缺陷。 发明内容 [0005] A conventional continuous straight-line drawing machine for cooling a wire is mainly for cooling a drawing die of a drawn wire and a large disk of a wound wire. The cooling method of the large plate can be divided into direct water cooling method and indirect water cooling method. The former is to rotate the large wire of the wound wire directly in the water tank. Although it has a good cooling effect, it must be blown dry in a very short time before the wire enters the next wire drawing die. The water stain on the surface of the wire causes the structure of the equipment to be complicated, consumes a lot of energy, and the drying is not thorough. A small amount of water is brought into the lubrication groove drawn by the next pass, which affects the lubrication effect; the latter traditional cooling method is to cool Water is sprayed onto the inner wall of the large rim to absorb the heat of the large rim and indirectly cool the wire. However, since the large plate is a rotating part, the sprayed cooling water is not in a closed state, and a certain amount of cooling water must flow to the outside of the large rim to make the wire Wetting, still need to be blown dry with a high-power compressed air machine, also has the above drawbacks.
