Abstract

The utility model provides a rolling mill multi-length shear control detection device, comprising a detection head respectively arranged at the inlet and outlet ends of a cooling device at the front of the multi-length shear, the two detection heads are electrically connected with the multi-length shear controller. The utility model is characterized in that an area sensor constructed by an emitter and a receiver is arranged at the outlet end of the cooling device, the output end of the receiver of the area sensor is connected with a middle relay having two constant-on contact points, wherein one constant-on contact point is connected with the input module of the multi-length shear controller, the other constant-on contact point is connected with the counter module of multi-length shear controller. In the case of no changing the prior device and control program, the to-be-milled workpiece can be sent into the controller by signal accurately and then the effective shear of the to-be-milled workpiece is performed by using the controller to control the multi-length shear, the utility model not only has effective detection effect but also has wide operation range, moreover, the utility model is not to be affected by the temperature of the to-be-milled workpiece surface, and therefore has reliable and safe operation.

Description

The milling train multiple length is cut the control detection device

Technical field

The utility model relates to a kind of pick-up unit, especially a kind of pick-up unit that provides the milling train multiple length to cut control usefulness.

Background technology

Usually in the operation of rolling to bar, will be through the finished product length after rolling much larger than charge length, therefore, must shear finished product and can change next procedure over to after the segmentation and handle, in the prior art, the equipment that finished product is carried out nibbling shear mostly is multiple length and cuts.Satisfying the condition of work that multiple length cuts is: in the import and the outlet that are positioned at the cooling system of multiple length before cutting two hot metal detectors are installed respectively, two detecting devices are all cut controller with multiple length and are electrically connected, after by controller the signal of gathering being compared, handles, promptly the may command multiple length is cut rolled piece is implemented to shear.Because existing low temperature hot metal detector only could operate as normal when measured object surface emissivity temperature reaches 300～1400 ℃, and the surface temperature of wearing after the water cooling is lower than 300 ℃ rolled piece, then be difficult to operate as normal, the signal that causes rolled piece to pass through can not normally be exported, and can not shear thereby multiple length is cut.Therefore, be necessary prior art is improved.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of milling train multiple length to cut the control detection device,, guarantees that multiple length is cut can shear rolled piece by signal with the detected rolled piece of accurate output on time.

The utility model is realized by following technical proposal: a kind of milling train multiple length is cut the control detection device, comprise be installed in respectively be positioned at multiple length before cutting the cooling device entrance point and the detection head of endpiece, two detection heads all are electrically connected with the controller that multiple length is cut, it is characterized in that being installed in the endpiece of cooling device by the area transducer that transmitter and receiver constitute, and the receiver output terminal of area transducer links to each other with the auxiliary reclay with two normally opened contacts, one of them normally opened contact links to each other with the load module that multiple length is cut controller, and another normally opened contact links to each other with the counting module that multiple length is cut controller.Deliver to respectively in the controller so that will there be signal that rolled piece passes through often to open the high level contact, realize the shearing control that controller is cut multiple length through two of relay.

Described auxiliary reclay coil two ends link to each other with power end respectively, so that power to relay coil.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can be under the situation that does not change original device and control program, only need auxiliary reclay at two normally opened contacts of detection head sensor receiver output terminal connecting band, and two normally opened contacts are connected respectively to load module and the counting module that multiple length is cut controller, rolled piece accurately can be sent in the controller by signal, cut by controller control multiple length again rolled piece is implemented effectively to shear, not only detect effectively, and working range is big, and not influenced by tested rolled piece surface temperature, reliable, safety.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

The inlet end of cutting the cooling device water cooling tube 3 between 5 at milling train 1 and multiple length is provided with thermometal detection head 7, endpiece at water cooling tube 3 is symmetrical arranged the area transducer (being that model is the optoelectronic switch of A80-4CR/E) that is made of transmitter 4 and receiver 6, wherein, milling train 1, cooling device water cooling tube 3, multiple length cut 5, thermometal detection head 7 and area transducer 4,6 are public equipment and element, rolled piece 2 is after milling train 1 comes out, after water cooling tube 3 coolings, enter multiple length and cut 5 cut-outs, as Fig. 1.The input end of area transducer receiver 6 is pressed power supply by switch 13, output terminal 8 links to each other with auxiliary reclay 9, a normally opened contact 10 of auxiliary reclay 9 links to each other with the counting module that multiple length is cut controller, another normally opened contact 11 links to each other with the load module that multiple length is cut controller, the coil of auxiliary reclay 9 connects power supply by power switch 12, as Fig. 2, wherein multiple length is cut controller and counting module and load module, auxiliary reclay thereof and is public technology.
