Abstract
The utility model relates to a ejecting rod device driven by a connecting rod. The device comprises an upper footstock, a lower footstock, a pedal and an ejecting rod, and is characterized in that the ejecting rod is thick at one end and thin at the other end, the upper footstock is placed at a hole with a diameter of phi 160mm in the center of a working table board of a single-pole hydraulic straightening machine, the lower footstock is fixed right under the working table board of a single-pole hydraulic straightening machine and corresponds to the upper footstock, the pedal is fixed on the lower footstock, the thin end of the ejecting rod penetrates through the upper footstock and the hole with the diameter of phi 160mm in the center of the working table board of the single-pole hydraulic straightening machine and is hinged with a connecting rod fixed by the pedal, and the ejecting rod can move vertically by 0mm-70mm. According to the device, the ejecting rod is small in stress and deviation-proof swing, good in stability and convenient to arrange and debug, the service life of the single-pole hydraulic straightening machine is prolonged, simultaneously, the device can be arranged on various presses, the labor intensity is reduced greatly, the working efficiency is improved, and reliability for safe working is increased.
Description
Technical field
The utility model belongs to the steel body structure device, and feature relates to the connecting rod that is installed on the single-column hydraulic straightening machine and drives pin-lift arrangement.
Background technology
The single-column hydraulic straightening machine is to carrying out alignment behind the high temperature solid solution of 20 rod operation roll of mill, carry out high tempering again, makes its interior tissue recrystallization, and the austenite homogenising has reached the purpose of turning, obtains satisfied high-quality service condition after reaching quenching.Because 20 rod operation roll of mill are woollen, almost be the twice of working roll, its specification is the oval steel of Ф 100mm*1800mm, the weight of 20 rod operation roll of mill is:
G=π r
2H ρ (density)=3.14*5
2* 221 jin/root of 1800=110920.5g ≈, the coefficientoffrictionμ of steel and steel=0.15*4(rubbing surface)=0.6, because frictional force is caused by gravitation, the gravity of every 20 rod operation roll of mill is G=mg=110.92kg*10kg/N=1109.2N, when 20 rod operation roll of mill woolen cloths are carried out alignment, on two v blocks of single-column hydraulic flattening machine worktable, when promoting, be exactly that 4 faces are subjected to frictional resistance so, suffered frictional force F=μ G=660N, it is large to push away woollen personnel's physical demands, and labour intensity is high.
Summary of the invention
The purpose of this utility model is large for the personnel's physical demands that pushes away woolen cloth that overcomes above-mentioned existence, labour intensity is high, and provide a kind of connecting rod to drive pin-lift arrangement, and the frictional force of alignment 20 rod operation roll of mill woolen cloths is reduced half, greatly reduce operating personnel's labour intensity and physical demands.
The technical solution of the utility model is:
Connecting rod drives pin-lift arrangement, comprise footstock, lower footstock, foot pedal, push rod, it is characterized in that: described push rod is that the thick end of an end is thin, the diameter that upper footstock is positioned over single-column hydraulic straightening machine work top center is place, Φ 160mm hole, lower footstock is fixed on vertical place, single-column hydraulic straightening machine work top below and corresponding with upper footstock, foot pedal is fixed on the lower footstock, the diameter that the taper end of push rod is passed single-column hydraulic straightening machine work top center is being hingedly connected together of the fixing connecting rod of Φ 160mm hole and upper footstock and foot pedal, push rod also can move up and down 0mm-70mm, and workpiece is slowly held up.The diameter of described push rod taper end is 10-30mm, and the diameter of push rod butt end is 70-100mm.
The utility model also comprises movable pulley and two bearings, and the butt end of described push rod is hollow, and movable pulley is placed the middle vacancy of the butt end of push rod, and is fixed in the push rod butt end at the axle of movable pulley by two bearings.
The utility model also comprises spring, and spring is fixed on the lower footstock and two ends link to each other with lower footstock with foot pedal respectively.
Push rod of the present utility model is stressed little, and anti-bias swing is little, and stability is better, and installation and debugging are more convenient, prolongs single-column hydraulic straightening machine service life, can be installed on all kinds of forcing presses simultaneously.Alleviate greatly labour intensity, improved operating efficiency, increased the reliability of trouble free service.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, the utility model comprises footstock 1, lower footstock 2, foot pedal 5, push rod 6, spring 4, movable pulley 7 and two bearings 8, and described push rod 6 is that the thick end of an end is thin, and the diameter of push rod taper end is 30mm, and the diameter of push rod butt end is 85mm; The butt end of described push rod is hollow, the diameter that upper footstock 1 is positioned over single-column hydraulic straightening machine work top center is place, Φ 160mm hole, lower footstock 2 is fixed on vertical place, single-column hydraulic straightening machine work top below and corresponding with upper footstock 1, foot pedal 5 is fixed on the lower footstock 2 by bolt 3, and spring is fixed on the lower footstock and two ends link to each other with lower footstock with foot pedal respectively; It is hinged with the fixing connecting rod of foot pedal 5 that the diameter that the taper end of push rod 6 is passed single-column hydraulic straightening machine work top center is Φ 160mm hole and upper footstock 1, the middle vacancy that movable pulley 7 is placed the butt end of push rod, and be fixed in push rod 6 butt ends at the axle of movable pulley 7 by two bearings 8, push rod 6 also can move up and down 0mm-70mm, and workpiece is slowly held up.
When coming alignment 20 rod operation roll of mill woollen with the utility model, the step pedal 5 that tramps with one's feet moves up and down push rod 6 in 0mm-70mm, hold up workpiece, workpiece holds up in the V-type groove of single-column hydraulic straightening machine work top, promoted the workpiece transverse shifting by the people, make the workpiece crooked position among two V-type grooves.Pushed by the single-column hydraulic straightening machine, make workpiece crooked position aligning, spring 4 makes foot pedal 5 return to original state.Wait work.
