Description
Technical Field
The invention belongs to the technical field of steel wire manufacturing, and particularly relates to a winding drum of a wire drawing machine.
Background
The wire drawing machine is a machining device commonly used in the metal wire product industry, takes wires of various materials and different diameters as raw materials, produces wire finished products or semi-finished products of different diameters through cold drawing, and is widely applied to industries such as wire drawing, rope making, cables, standard parts and the like at home and abroad.
The winding drum of the wire drawing machine is an important part on the wire drawing machine, the winding drum of the wire drawing machine is mainly used for drawing a steel wire wound on the winding drum, and the steel wire drawn by the winding drum of the wire drawing machine is sent to the next procedure by the wire outlet guide wheel.
In the drawing process of the wire drawing machine, 60-70% of drawing heat needs to be taken away by cooling a winding drum; the cooling mode has wind cooling and water cooling, but common fountain water cooling sprays the cooling water that will have certain pressure on the reel inner wall after the reducing nozzle with the cooling water pressure boost, and the steel wire transmits the drawing heat on the reel and is taken away.
Based on above-mentioned water cooling's process, the inner structure of reel is equipped with annular water cavity at its inboard, the stack shell of reel is exactly the lateral wall of annular water cavity, the cooling water sprays on the lateral wall of annular water cavity, the heat conduction on the wire of winding on the rotatory reel stack shell gives the stack shell, also conduct the lateral wall for annular water cavity, the lateral wall gives the water of annular water cavity with the heat conduction, water takes away the heat through flowing, realize reducing the mesh of wire temperature.
Because the contact time of unit volume's water and annular water cavity wall body is long in the annular water cavity, this makes the temperature of the longer water of dwell time also rise a lot, and higher temperature's water is unfavorable for carrying out better cooling, and the difference in temperature in each region is big in the annular water cavity moreover, also makes the cooling effect poor.
Disclosure of Invention
The invention aims to provide a winding drum of a wire drawing machine, and solves the problems that in the prior art, the contact time of unit volume of water and the wall body of an annular water cavity is long, and the cooling effect is poor.
The winding drum of the wire drawing machine comprises a winding drum body, wherein an annular water cavity is formed in the wall of the winding drum body, a water main for leading water flow is arranged in the winding drum body, the winding drum further comprises a plurality of water distribution pipes communicated with the water main, a plurality of partition plates are arranged in the extending direction of the annular water cavity to divide the annular water cavity into a plurality of cooling cavities, a water inlet hole is formed in the inner side of one end of each cooling cavity in a surrounding mode, a water outlet hole is formed in the inner side of the other end of each cooling cavity in a surrounding mode, and the diameter of the water outlet hole is larger than that of the water inlet hole; the water outlets on all the cooling cavities are communicated with water guide pipes, all the water guide pipes are communicated through the same water discharge pipe, and each water inlet is communicated with one water distribution pipe.
The working principle and the beneficial effects of the scheme are as follows: adopt the baffle to separate into a plurality of cooling chambeies with annular water cavity, the independent intercommunication cooling water in every cooling chamber, the cooling water of unit volume shortens with the contact time in annular water cavity, strengthens the cooling effect, also makes the temperature in each region of annular water cavity more close, reaches more even, faster cooling effect.
Furthermore, one end of the water distribution pipe communicated with the water inlet hole is provided with a pressurizing nozzle. Increase the water velocity, the reel body can be continuous cools off the steel wire, can also prevent through the rapid movement of rivers and impact that the cooling water velocity of rivers in the annular water cavity from depositing at a slow speed and producing the incrustation scale, has guaranteed the heat exchange efficiency of reel.
Further, the outer side wall of the annular water cavity is provided with a plurality of insections. Specific insection is the inboard that is located the lateral wall of annular water cavity, sets up the surface that lies in smooth surface optimization unevenness with the conventionality different like this, has also increased the area of contact of lateral wall with water when increasing heat radiating area, and the last absorptive heat of reel body can in time conduct feedwater, therefore, the cooling effect obtains obviously improving.
Further, the insection is a thread tooth or a sawtooth shape.
Furthermore, an electroplating rust-proof layer is arranged on the inner wall of the annular water cavity. Prevent the inner wall of the annular water cavity from rusting.
Further, the outer surface of the winding drum body is provided with a nickel-based alloy powder remelting layer. Spraying particles of the nickel-based alloy powder on the outer surface of the winding drum body at a high speed, and then melting the alloy powder to form a hardened alloy protective layer on the outer surface of the winding drum body; the wear resistance, the corrosion resistance and other properties of the winding drum body are improved, and the service life of the winding drum is prolonged.
