Description
Technical field
The utility model relates to fine spining machine, especially the tensioner of fine spining machine.
Background technology
The rolling disk of fine spining machine is under motor-driven, and by spindle band and under the tensioning of tension pulley, the transmission spindle rotates.At present, a kind of pair of tension pulley device arranged on the market, two tension pulleies are connected with support arm respectively, the other end of each support arm is fixedlyed connected with little axle (10), on the little axle spring torque arm is housed, and connects with spring between two torque arm, in the spring torque arm limited block is housed, the tension force box adopts the snap-in complex structure of forward and backward, last three surface elastics, and fixedly the tension axis of tension force box is passed by tension force box middle part, and axle is a sleeve type with the installation form of box.The above-mentioned pair of shortcoming that the tension pulley device exists: (1) tension force box and tension axis adopt sleeve structure, during the maintain and replace part, need the tension axis dismounting, and all tension pulleies that need will be sleeved on the axle are pulled down operating difficulties, time-consuming.In addition, axle radially wobbles for preventing with the sleeve structure of box, and fit tolerance requires high, has increased manufacture difficulty.Spring between (2) two torque arm adopts regular length, and under the situation of using different wharve diameters and spindle band error in length and elongation, spindle band tension force is non-adjustable, easily causes the ingot of spindle and spindle fast poor.The fastening of (3) three tension force boxes adopts snap, complex structure sealing poor stability, and service life is short.The limited block of (4) two opening different width of tubesheet hole groove and last tension force box are same part, spare part cost height.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of fine spining machine two tension pulley devices, have simple and reasonable for structure, good airproof performance, advantage such as easy to loading and unloading.
Following technical measures have been taked for realizing goal of the invention the utility model: the two tension pulley devices of a kind of fine spining machine, comprise: under rolling disk drives, by spindle band and in two tension pulleies under the tensioning, the rotation of transmission spindle, two tension pulleies are connected with support arm respectively, the other end of each support arm is fixedlyed connected with little axle, on the little axle spring torque arm is housed, connect with spring between two spring torque arm, limited block is equipped with in two spring torque arm tops, forward pull box (front of box) fastens with backward pull box (back of box), and forward and backward tension force box middle part is connected with tension axis.Described little axle is equipped with the left spring torque arm on its left-small-axis, right spring torque arm is housed on the right-small-axis, the rear end of left spring torque arm, right spring torque arm respectively with backward pull box sliding bearing, the front end of left spring torque arm, right spring torque arm respectively with forward pull box sliding bearing, hook has the adjustable spring assembly between the left and right spring torque arm.
Described adjustable spring assembly is: carbine hangs in the spring torque arm of a left side (or right), and screw rod is connected with spring with pin, and the other end of screw rod is combined with adjusting nut by connecting ring and right (or left side) spring torque arm hook on the screw rod.Described forward and backward tension force box is connected with tension axis, be on forward and backward tension force box, position that tension axis is installed offers breach, the tension force shaft-cup that is mated in the indentation, there setting, and being screwed.Being connected between described forward pull box and the backward pull box, adopt the Hafu type fastening structure, and fastening with counter-sunk screw.The limited block of described left spring torque arm top, the angle of oscillation α of its opening groove width
1=4 °, the limited block of right spring torque arm top, the angle of oscillation α of its opening groove width
2=30 °.On the described forward pull box, the position that is positioned at adjusting nut has the adjusting window of a sealing.
The utility model compared with prior art because the spring between the left and right spring torque arm is the adjustable spring assembly, changes the length of spring by adjusting nut, thereby can change the size of spindle band tension force, ingot speed high conformity.On the tension force box, a window is offered in corresponding adjusting nut position simultaneously, does not need to take apart the tension force box and just can regulate, and has made things convenient for use.Because the tension force box has adopted with the mounting structure of tension axis and has separated Hafu type, be about to the tension force box and be positioned at the tension axis centerline and offer breach, the tension force shaft-cup in that the setting of breach correspondence position is mated is screwed.When needs overhaul, just can open shaft-cup as long as take off screw, take out the tension force box, realized that single cover changes, do not influence other tension force box, advantage such as it is easy to have loading and unloading, and tension axis processing is simple.Simultaneously, fastening with screw, firm stable, in addition, breathe out furan and fasten good airproof performance.Because the setting of two limited blocks and the difference of opening groove width thereof make its angle of oscillation different, have not only prevented part collision accident, and have improved the adaptability to the occasion position, in addition, two limited blocks are separate component, and the spare part cost is low.
