Description
Technical field
The utility model relates to sheet metal strip Precise asymptotics equipment technical field, particularly relates to a kind of coiler for trimmings damper mechanism.
Background technology
The coiler for trimmings that current most of Precise asymptotics uses, primarily of parts compositions such as frame, pressure roller, hydraulic cylinder, transmission device and firm bankings, pressure roller is connected with frame by connecting rod, is swung by Driven by Hydraulic Cylinder.During coiler for trimmings work, hydraulic cylinder drives pressure roller pressure by connecting rod, motor is rotated by decelerator driving spool and starts to batch slitter edge, and it is real to ensure its volume that pressure roller compresses slitter edge volume all the time, and the scrambling of rolling up due to slitter edge causes the speed of coiler for trimmings to be difficult to mate with unit speed.Coiler for trimmings excessive velocities may draw bad disc shear edge, so the rotating speed of unit real work speed and maximum slitter edge roll diameter compute motor all pressed by current most of coiler for trimmings, so just cause the linear velocity of coiler for trimmings lower than unit real work speed, slitter edge is caused to cheat windrow, so have many slitter edges to enter coiler for trimmings, and the swing of pressure roller is by Driven by Hydraulic Cylinder, due to the Incoercibility of liquid simultaneously, thus cause the high vibration of equipment, affect its service life.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of coiler for trimmings damper mechanism, and structure is simple, practical, easy to maintenance, achieves the requirement reducing fault, improve service life of equipment.
In order to achieve the above object, the technical solution of the utility model is:
A kind of coiler for trimmings damper mechanism, comprises pressure roller 2, and pressure roller 2 is connected with frame 4 by connecting rod 3, and cylinder 1 drives and connects connecting rod 3, and on connecting rod 3, also install a damper 6, the oscillation center of connecting rod 3 is equipped with a rotary transformer 7 simultaneously.
Described cylinder 1 is middle trunnion type cylinder, and its rod chamber is equipped with pressure relief valve.
The utility model can accurate measurements slitter edge volume diameter, the operating rate of coiler for trimmings is mated with the operating rate of unit, reject dump can not windrow, avoid many slitter edges and enter the equipment high vibration that coiler for trimmings causes simultaneously, bad disc shear edge can not be drawn again simultaneously, thus improve service life of equipment, there is good popularizing application prospect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, a kind of coiler for trimmings damper mechanism, comprise cylinder 1, pressure roller 2, connecting rod 3, frame 4, damper 6 and rotary transformer 7, cylinder 1 drives and connects connecting rod 3, and pressure roller 2 is connected with frame 4 by connecting rod 3, and pressure roller 2 both can rotate around its center and also can swing with connecting rod 3, the swing of pressure roller 2 swings realization by cylinder 1 drive link 3, thus making coiler for trimmings in the course of the work, pressure roller 2 compresses slitter edge volume all the time, ensures that slitter edge volume volume is real.Utilize the compressibility of gas, pressure roller 2 adopts cylinder 1 to drive, and reduces the vibration caused because slitter edge roll-shape is irregular in coiling process, also installs a damper 6, for apparatus with shock absorbing on connecting rod 3 simultaneously.The oscillation center of connecting rod 3 is equipped with a rotary transformer 7, for calculating the diameter of slitter edge volume.
Described cylinder 1 is middle trunnion type cylinder, and its rod chamber is equipped with pressure relief valve.
Operation principle of the present utility model is: when the band steel in unit need carry out trimming process, and delivered to through circle shear by band steel and cut the place's of cutting excision weld seam, coiling machine finishes up, and now unit is shut down completely, and the coil of strip on coiling machine unloads by coil stripping car; Meanwhile, the slitter edge cut is wrapped on coiler for trimmings spool 5, pressure roller 2 is depressed, after confirming safety, coiler for trimmings random groups speed coordinated operation.Along with the carrying out of batching, the radius of slitter edge volume constantly becomes large, pressure roller 2 is constantly lifted, pressure now in cylinder 1 rod chamber raises, when reaching the pressure of pressure relief valve setting, pressure relief valve work, thus can ensure that pressure roller 2 compresses slitter edge volume all the time, make slitter edge volume real, again can not because of the too large damage cylinder 2 of pressure.When slitter edge volume reaches the maximum coil diameter of setting, spool 5 stops, and pressure roller 2 lifts, and is discharged in scrap basket by slitter edge volume.Be arranged on the damper 6 of connecting rod 3 pivot for absorbing the vibration of pressure roller 2 in coiling process.
With reference to Fig. 2, the angle changing value a of what rotary transformer 7 was measured is connecting rod 3 in the coiler for trimmings course of work, the diameter of slitter edge volume can angle calculation obtain thus.The oscillation center of connecting rod 3 and the centre distance of spool 5 are A, and the length of connecting rod 3 is L, and the initial angle of connecting rod 3 and two lines of centres is a
0, the radius of pressure roller 2 is R, just can show that the computing formula of slitter edge volume radius is according to the cosine law
The utility model can accurate measurements slitter edge volume diameter, the operating rate of coiler for trimmings is mated with the operating rate of unit, reject dump can not windrow, avoid many slitter edges and enter the equipment high vibration that coiler for trimmings causes simultaneously, can not bad disc shear edge be drawn again simultaneously, thus improve service life of equipment.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
What finally illustrate is, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and description just illustrates principle of the present utility model, under the prerequisite not departing from principle of the present utility model and scope, various changes and modifications all should be encompassed in the middle of right of the present utility model.
