Abstract

The utility model discloses the buffer unit of cold-rolling mill, including base member case, frame, connecting rod and actuating device, the two ends of described frame are provided with buffer unit.This utility model simple in construction, when frame is in outer dead point or inner dead point, the energy that energy-storaging spring storage is certain so that frame is when changing the direction of motion, and the alternate load that main drive bears has reduced, thus reduces the fluctuation of current of electric.

Description

The buffer unit of cold-rolling mill
Technical field
This utility model relates to mechanical field, is specifically related to the buffer unit of cold-rolling mill.
Background technology
Cold pilger mill is to utilize annular distance shape that hollow forging is carried out the process equipment of cold conditions rolling.These facility have preferable cogging Can, also can roll the metal seamless tube of general precision.Cold pilger mill maximum feature is that stock utilization is high, and precision and surface thick Rugosity is superior to drawn tube.Cold-rolling mill is made up of operating mechanism and drive mechanism, wherein: operating mechanism by frame, roll, roll The part such as roller bearing, roll-adjusting gears, guide device is constituted;Drive mechanism by herringbone gear, reductor, roll, coupling spindle, The part such as shaft coupling is constituted.Cold-rolling mill uses motor to pull reinforcing bar, utilizes the load bearing roller of cold-rolling mill, working roll jointly power to be executed It is added on two faces of hollow forging.Realize rolling out the purpose of different-diameter hollow forging by the size changing two roll seams.Mesh Before, the operating mechanism of dual roll type cold-rolling mill can be reduced to slider-crank mechanism.For making pipe pass through above transmission main shaft, it is necessary to Making rolling centerline be higher than crank up centrage, therefore, the operating mechanism of cold-rolling mill, i.e. stand arrangement motor system, mostly is One offset slider-crank mechanism.The operating mechanism of dual roll type cold-rolling mill can be reduced to slider-crank mechanism.For making pipe from biography Pass through above dynamic main shaft, it is necessary to make rolling centerline be higher than crank up centrage, therefore, the operating mechanism of cold-rolling mill, i.e. machine Rack device motor system, mostly is an offset slider-crank mechanism.For slider-crank mechanism, no matter the invariablenes turning speed of crank with No, motion produces inertia force always, it will be directly connected to duty and the service life of cold-rolling mill.Inertia force big Little quality with component and acceleration are proportional, i.e. with the quality of component, throw of crankshaft, crank rolling velocity square proportional.And The quality of dual roll type cold-rolling mill movable part (operating mechanism) is the biggest, thus operating mechanism is at the inertia produced at the volley Power is the biggest.When crank rotates a circle, inertia force changes twice, and moment of inertia changes four times, thus gross energy also will become Change four times.It addition, in rolling-mill housing is moved, we leave frame outside the farthest extreme position of crank up centrage is called Stop, calls inner dead point extreme position nearest for distance crank up centrage, wink when frame is in outer dead point or inner dead point Shi Sudu is 0.It is continually changing the appearance with peakload so that the main drive of milling train bears the biggest friendship due to energy Varying load, will cause the fluctuation of current of electric, affect electrical machinery life.
Summary of the invention
The technical problems to be solved in the utility model is the buffer unit of cold-rolling mill, solves the continuous of prior art energy The problem that the appearance of change and peakload affects electrical machinery life.
This utility model is achieved through the following technical solutions:
The buffer unit of cold-rolling mill, including base member case, frame, connecting rod and actuating device, the two ends of described frame are provided with Buffer unit.
The further improvement project of this utility model is that described buffer unit includes energy-storaging spring, spring pedestal and spring housing Cylinder.
This utility model further improvement project is that described spring pedestal is fixedly connected in frame.
This utility model further improvement project is that described spring spool is fixedly connected in base member case.
This utility model further improvement project is that one end of described energy-storaging spring is fixedly connected on spring pedestal, The other end is fixedly connected in spring spool.
This utility model compared with prior art, has the advantage that
This utility model simple in construction, when frame is in outer dead point or inner dead point, the energy that energy-storaging spring storage is certain, Making frame when changing the direction of motion, the alternate load that main drive bears has reduced, thus has reduced current of electric Fluctuation.
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model (when not containing base member case).
Detailed description of the invention
As shown in Figures 1 and 2, this utility model includes base member case 01, frame 02, connecting rod 04 and actuating device 05, institute The two ends stating frame 02 are provided with buffer unit 03, and described buffer unit 03 includes energy-storaging spring 32, spring pedestal 31 and spring housing Cylinder 33, described spring pedestal 31 is fixedly connected in frame 02, and described spring spool 33 is fixedly connected in base member case 01, described One end of energy-storaging spring 32 is fixedly connected on spring pedestal 31, and the other end is fixedly connected in spring spool 33.
It should be pointed out that, for those skilled in the art, without departing from this utility model principle On the premise of, it is also possible to making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
