Description
Technical field:
The present invention relates to pressure processing machinery equipment, a kind of periodic double-roller cold pilger mill of more specifically saying so.
Background technology:
At present, what the periodic double-roller cold pilger mill adopted is crank offset slide block mechanism, and in its course of work, speed and acceleration change, and mechanism affords very big inertia force and inertia torque.For huge inertia force and the inertia torque of balance milling train in rolling motion process, the balanced controls of manufacturer's employing both at home and abroad have following five kinds: VE, horizontal equilibrium, secter pat balance, hypocycloid balance, air-balance.Specifically, the horizontal equilibrium effect is better, but the manufacturing process complexity, and floor space is big, operating difficulties; The complicated in mechanical structure of hypocycloid balance mode, mechanism is huge, and weight of equipment is higher; The air-balance effect is lower, fault rate height, the maintenance of milling train, repairing inconvenience; The secter pat balance can be divided into single secter pat balance, double-sector block balance, vertical secter pat balance, and single secter pat is general with vertical secter pat counterbalance effect, and the double-sector block counterbalance effect is better; The counterbalance effect of VE is best, and weak point is that the melt pit on basis is darker, the foundation cost height, and machinery wieght is big, the manufacturing cost height of milling train.
Summary of the invention:
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of full equilibration period formula not have the biasing double-roller cold pilger mill, be not provided with and balanced controls by there being biasing, improve the balance inertia properties, improve mill speed, improve running stability, simplify manufacturing process simultaneously, be convenient to maintenance, reduce occupation area of equipment.
Technical solution problem of the present invention adopts following technical scheme:
Design feature of the present invention is that crank connecting rod sliding block mechanism is set, the pass assembly is arranged on the mainframe as slide block, be in the both sides of described mainframe and be symmetrical set two groups of balances and driving mechanism, described driving mechanism is to be connected by connecting rod with mainframe with the crank gear that has balance weight, and rolling centerline is by the center of crank gear; Balanced controls are set to the balance weight gear, and power input gear is meshed with crank gear and balance weight gear respectively.
Design feature of the present invention also is:
The balance weight gear is to be meshing with each other by upward balance weight gear set up and down and following balance weight gear to constitute, the center line of power input gear in height departs from the rolling centerline height, power input gear or with last balance weight gears engaged, or with following balance weight gears engaged.
The pass assembly is a pair of format roll, and the corresponding a pair of format roll driven wheel that is provided with is positioned at the both sides of mainframe, constitutes mainframe translation transmission with synchromesh gear and the driving rack that fixedly installs.
As the power input gear uniform rotation of main motor-driven part, power input gear and crank gear engagement drive the crank gear uniform rotation among the present invention.Crank gear drives mainframe by connecting rod and moves back and forth.The pass assembly is reciprocating jointly with mainframe in the mainframe, thereby realizes translation and rotate superimposed motion, finishes rolling to pipe with this.
Compared with the prior art, beneficial effect of the present invention is embodied in:
One aspect of the present invention is by being provided with balance weight, with this inertia that comes balance portion mainframe and connecting rod to be produced on crank gear; On the other hand by the balance weight gear being set, the inertia that the inertia force that is produced with the balance weight gear comes further balance mainframe and pass assembly to produce.Make mechanism inertia force and the mutual balance of moment of inertia by above two aspect mechanisms, thereby can greatly improve the mill speed of milling train and the performance that operates steadily.
Description of drawings:
Fig. 1 looks schematic diagram for overall structure master of the present invention.
Fig. 2 is an overall structure schematic top plan view of the present invention.
Number in the figure: balance weight gear, 4 crank gears, 5 connecting rods, 6 pass assemblies, 7 mainframes, 8 driving racks, 9 rolling centerlines, 10 synchromesh gears, 11 balance weights on 1 power input gear, the 2 times balance weight gears, 3.
Below pass through the specific embodiment, and in conjunction with the accompanying drawings the present invention be further described:
The specific embodiment:
Referring to Fig. 1, Fig. 2, crank connecting rod sliding block mechanism is set, pass assembly 6 is arranged on the mainframe 7 as slide block, be in the both sides of mainframe 7 and be symmetrical set two groups of balances and driving mechanism, driving mechanism is to be connected by connecting rod 5 with mainframe 7 with the crank gear 4 that has balance weight 11, and rolling centerline 9 is by the center of crank gear 4; Balanced controls are set to the balance weight gear, and power input gear 1 is meshed with crank gear 4 and balance weight gear respectively.
Shown in Figure 1, the balance weight gear can be to be meshing with each other by upward balance weight gear 3 set up and down and following balance weight gear 2 to constitute, rolling centerline 9 is by last balance weight gear 3 and following balance weight gear 2 pitch circle meshing points, the center line of power input gear 1 in height departs from the height of rolling centerline 9, power input gear 1 or with 3 engagements of last balance weight gear, or mesh with following balance weight gear 2.
Fig. 1, shown in Figure 2, pass assembly 6 is a pair of format roll, the corresponding a pair of synchromesh gear 10 that is provided with is positioned at the both sides of mainframe 7, constitutes mainframe translation transmission with synchromesh gear 10 and the driving rack 8 that fixedly installs.
In concrete the enforcement, about two following balance weight gear 2 coaxial settings, about two go up the 3 coaxial settings of balance weight gear, about two power input gear 1 coaxial settings, about two crank gears 4 be separately positioned on about on two axles, connecting rod 5 one ends are connected on the crank gear 4 by bearing pin, the other end is connected on the mainframe 7 by bearing pin, pass assembly 6 is arranged on the mainframe 7, the left and right sides of mainframe 7 is a synchromesh gear 10, synchromesh gear 10 is meshing with each other with the driving rack 8 that fixedly installs respectively, forms mainframe 7 translation transmissions.
