Abstract
The utility model discloses an improved high-speed wire rod vertical loop device. The improved high-speed wire rod vertical loop device comprises a loop wheel and a loop wheel shaft, wherein the loop wheel axle is a stepped shaft, a lubricating oil channel is arranged inside the loop wheel shaft, one end of the lubricating oil channel is arranged at the end portion of the loop wheel shaft and the other end of the lubricating oil channel is arranged on the peripheral wall of the middle of the loop wheel shaft. Two end covers of the loop wheel are arranged inside flanges at two ends of the loop wheel. The improved high-speed wire rod vertical loop device improves design and installment faults, prolongs service life, reduces processing cost of replacement parts and is easy to maintain.
Description
Technical field
The utility model relates to the vertical looper of a kind of improved high-speed rod.
Background technology
High line unit is arranged the vertical looper of 1#, the vertical looper of 2#, the vertical looper of 3# between 11H to 14V milling train, amount to 3 vertical looper devices.The major function of 3 vertical loopers is: it makes rolled piece between adjacent frame without storing certain kink amount under the tension force, buffering link when speed is inharmonious between frame, dynamic speed changes the workpiece measurement fluctuation that causes between each frame thereby eliminate in the operation of rolling.The design feature of 3 vertical loopers: support the carrying roller of rolled piece by the little roller bearings of frictional resistance, reduced the surface tear to rolled piece, it is arranged on the swing span, utilize cylinder rapid-action characteristics directly to drive swing span, make carrying roller have certain active force and supporting all the time rolled piece, avoid rolled piece to cause wave.Especially most important when rolling welding wire steel.
The online looper that uses has following defective: 1, the kink wheel shaft is without tank filler sleeve, and causing can't be grease-added lubricated to bearing online, the frequent scaling loss of bearing.2, the bearing type selecting is less, and original-pack bearing designation is 6209 deep groove ball bearings, and the loading ability of bearing load-bearing capacity is lower.3, the gland material is the 45# steel, is installed in kink wheel outside, and its outer rim directly contacts with blank, and the attachment bolt that serious wear and itself and kink are taken turns ruptures in the operation of rolling easily, and service life is lower.4, the material of kink wheel is the 45# steel, and not wear-resistant, frequent wear is serious.5, be unkitted cooling water, cause the temperature rise of kink wheel too high, lubricating grease is heated, and dilution is deviate from, bearing reduces service life, kink wheel wear resistance decrease.6, playing cover wheel shaft and deflector roll seat is interference fits, dismounting inconvenience, and site space is little in addition, minimum 1.5 hours of the time of at every turn changing.Because the existence of above defective, the service life of vertical looper is extremely low, and average life was at 2 days.And because looper when in use breaking down, tends to cause becoming silted up bar heap steel, all affect larger on lifting and the lumber recovery of rhythm of production.More seriously, when rolling welding wire steel, because if the lower hardness of welding wire steel without looper, is easy to cause silt bar heap steel, be the bottleneck place of variety development.
Summary of the invention
The purpose of this utility model is to provide a kind of improved high-speed rod to found looper, can effectively improve lubricant effect, extension device service life.
The purpose of this utility model is to realize like this, a kind of improved high-speed rod founds looper, comprise kink wheel and kink wheel shaft, the kink wheel shaft is multidiameter, in the kink wheel shaft grease channel is being set, one end of grease channel is positioned at the end of kink wheel shaft, and the other end of grease channel is positioned on the periphery wall at kink wheel shaft middle part; The two ends end cap of kink wheel is installed in the wheel rim at kink wheel two ends by bolt.
The utility model is by arranging grease channel and bearing (ball) cover being positioned in the wheel rim of kink wheel, improved lubricant effect, eliminated the wear-out defect of kink wheel, effectively improved its design and installation defective, improved service life, reduce the spare part processing cost, be easy to equipment maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
A kind of improved high-speed rod founds looper, as shown in Figure 1, comprise kink wheel 2 and kink wheel shaft 5, kink wheel shaft 5 is multidiameter, the kink wheel shaft 5 interior grease channels 4 that arranging, one end of grease channel 4 is positioned at the end of kink wheel shaft, and the other end of grease channel 4 is positioned on the periphery wall at kink wheel shaft 5 middle parts; The two ends end cap 1 of kink wheel 2 is installed in by bolt in the wheel rim at kink wheel two ends, in order to bearing 3 is compressed, eliminates simultaneously the wear-out defect of end cap 1, avoids directly contacting with blank, and infinitely prolong service life, abrasion condition again do not occur.Because online kink wheel bearing 3 rotating speeds are 2800r/min, although being 6209 deep groove ball bearing rotating speed, bearing originally meets the demands, and bearing capacity is lower, and bearing is shorter service life.Now change 6311 deep groove ball bearing into, bearing load carrying capacity has increased by 120%, the phenomenal growth in service life.Original-pack kink wheel material is the 45# steel, and not wear-resistant, frequent wear is serious.It is can not use with regard to serious wear about 1 week that kink is taken turns average life.Now change high-abrasive material GSiMnMoVXt into, be 2-3 month service life, and significantly prolong service life, and effect is remarkable.
