Abstract
The utility model relates to a front steel-plate pressing head device of a hot straightening machine. The front steel-plate pressing head device of the hot straightening machine is composed of a frame, a pressing plate, a hydraulic cylinder and a hydraulic control valve stand, wherein the frame is arranged on two sides of an inlet roller bed of the hot straightening machine, a guide trough is arranged on the frame, the pressing plate is arranged in the guide trough, a pressing head used for flattening a steel plate is fixed on the pressing plate, and the pressing plate is driven by the hydraulic cylinder at the top of the frame to be capable of moving vertically. By means of the front steel-plate pressing head device of the hot straightening machine, the steel plate with the upward cocked head can be directly flattened, it is avoided that the surfaces of straightening rollers are damaged in a colliding mode, the problem that the cocked head of the steel plate damages the bodies of the straightening rollers in a colliding mode is solved effectively, non-planned shut-down time is shortened, product quality is improved, and production cost is lowered.
Description
Technical field
The utility model relates to a kind of thermal straightening machine front spring indenter device that is applicable to hot rolled steel plate production line, can flatten processing to steel plate nose, avoids occurring the wound problem of the thermal straightening machine body of roll of steel plate nose.
Background technology
On hot rolled steel plate production line, steel plate is from mill milling completes, must be aligned by thermal straightening machine, some thinner steel plates are from milling train out time, easily occur that head upwarps phenomenon, the smoothing roll roll surface of at this moment will wounding, and then affect plate surface quality, gently need artificial reconditioning surface of steel plate to increase workload, heavy cause plate surface quality defective.At this moment with regard to shutting down, smoothing roll is carried out to reconditioning, cause whole production line to be shut down, increase nonscheduled down time, in downtime, waste again mass energy, increased production cost.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art
,the utility model provides a kind of effective wound problem of the smoothing roll body of roll of steel plate nose that solved, and has minimizing nonscheduled down time, improve the quality of products, and the thermal straightening machine front spring indenter device of the feature that reduces production costs
.
The utility model solves the technical scheme that its technical problem adopts: a kind of thermal straightening machine front spring indenter device, formed by framework, pressing plate, hydraulic cylinder and hydraulic control valve platform, frame installation is in thermal straightening machine inlet roller way both sides, on framework, be provided with guide groove, pressing plate is installed in guide groove, on pressing plate, be fixed with one for flattening the pressure head of steel plate, pressing plate can move up and down by the driving of the hydraulic cylinder of frame roof.
Described pressure head and inlet roller way are designed with chain, and pressing plate does not lift and reaches upper limit, and roller-way cannot move.
Be provided with hydraulic valve platform on described thermal straightening machine front spring indenter device side, hydraulic valve platform and thermal straightening machine share Hydraulic Station.
Described thermal straightening machine front spring indenter device maximum working pressure (MWP) 160bar, approximately 50 tons of maximum pressing plate power.
The beneficial effects of the utility model are: can will occur that the steel plate that head upwarps phenomenon directly flattens by this device; thereby avoid wounding smoothing roll roll surface; effectively solve the wound problem of the smoothing roll body of roll of steel plate nose; reduce nonscheduled down time; improve product quality, reduced production cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is state diagram before the utility model uses;
Fig. 3 is state diagram after the utility model uses.
In figure: 1-framework, 2-pressure head, 3-pressing plate, 4-hydraulic cylinder, 5-guide groove, 6-inlet roller way.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Referring to Fig. 1～Fig. 3, a kind of thermal straightening machine front spring pressure head 2 installs, by framework 1, pressing plate 3, hydraulic cylinder 4 and hydraulic control valve platform form, framework 1 is arranged on thermal straightening machine inlet roller way 6 both sides, on framework 1, be provided with guide groove 5, pressing plate 3 is installed in guide groove 5, on pressing plate 3, be fixed with one for flattening the pressure head 2 of steel plate, pressing plate 3 can move up and down by the driving of the hydraulic cylinder 4 at framework 1 top, pressure head 2 and inlet roller way 6 are designed with chain, pressing plate 3 does not lift and reaches upper limit, roller-way cannot move, at the other hydraulic valve platform that is provided with of described thermal straightening machine front spring pressure head 2 devices, hydraulic valve platform and thermal straightening machine share Hydraulic Station, thermal straightening machine front spring pressure head 2 installs maximum working pressure (MWP) 160bar, approximately 50 tons of maximum pressing plate 3 power.
Can will occur that the steel plate that head upwarps phenomenon directly flattens by this device; thereby avoid wounding smoothing roll roll surface, effectively solved the wound problem of the smoothing roll body of roll of steel plate nose, reduced nonscheduled down time; improve product quality, reduced production cost.
