As China is in the historical stage of rapid development of urbanization, the demand for building steel is great. As a main building steel material, deformed steel bars occupy a large proportion of the production of Chinese steel materials all the time. The deformed steel bar is made of steel which is necessary for more than medium-sized building components, the cross rib geometry of the domestic deformed steel bar mainly comprises three types of spiral, herringbone and crescent, and the deformed steel bar is mainly based on mechanical process performance or mechanical strength index on the basis of meeting the requirement of the gripping performance required by engineering design.
The specification of the deformed steel bar should be listed in the trade, and generally includes the type code, the nominal diameter of the steel bar, the nominal weight, the specified length, the allowable difference value of the above indexes, and the like. The rolling process of the general deformed steel bar is to carry out negative deviation control on the difference value between the calculated weight of the finished product flying shear and the actual weighing weight of the blank scale, and the negative deviation control of the deformed steel bar finished product can be influenced because the stop position of the blank is difficult to accurately control by the steel feeding roller way and the weighing error of the blank scale is caused by the unstable position of the steel feeding roller way.
Therefore, the blank weighing and positioning device in the screw-thread steel rolling process needs to be designed, has a simple structure, can solve the problem of accurate stop of the rolled steel blank in a roller way, and ensures that the negative deviation of the screw-thread steel finished product can be stably controlled.
Disclosure of Invention
An object of the utility model is to provide a blank positioner that weighs in screw-thread steel rolling solves current advance the steel roll table to be difficult to accurate control to the off-position of blank, leads to the unstable problem of its position.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a blank positioner that weighs in screw-thread steel rolling, includes roll table and the trailing arm that weighs, wherein, the trailing arm that weighs includes a plurality ofly, and a plurality of trailing arms that weigh are arranged along the even interval of roll table traffic direction, still include: the horizontal telescopic unit sets up the roll table is terminal, the telescopic link end-to-end connection of horizontal telescopic unit has the dog that is used for blockking the blank, and first hot metal detector sets up the middle part of roll table, second hot metal detector sets up the end of roll table, and be located before the horizontal telescopic unit.
Preferably, the weighing bracket comprises: the support arm is connected with the connecting arm in a V-shaped manner.
Preferably, the first hot metal detector and the second hot metal detector are both arranged on one side of the roller way through vertical supporting rods.
Preferably, the transverse telescopic unit is a cylinder.
The utility model has the advantages that:
this blank positioner that weighs in screw-thread steel rolling, simple structure has solved current advance the steel roll table and is difficult to accurate control to the off-position of blank, leads to its unstable error that arouses the blank balance to can influence the problem of the off-set control of screw-thread steel finished product, ensure that screw-thread steel finished product off-set can be by stable control.
Drawings
Fig. 1 is a top view of the present invention;
FIG. 2 is a schematic view of a weighing bracket;
in the figure: 1. the device comprises a roller table, 2, a rolling mill, 3, a weighing support arm, 3-1, 3-2, a connecting arm, 3-3, a cylinder for the support arm, 4, a rolled blank, 5, a first hot metal detector, 6, a second hot metal detector, 7, a stop block, 8 and a cylinder for the stop block.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Unless defined otherwise, all references to up, down, left, right, front, back, inner and outer directions herein are to be interpreted as referring to up, down, left, right, front, back, inner and outer directions in the drawings to which the invention is applied, and all references are hereby incorporated herein by reference.
The utility model provides a blank positioner that weighs in screw-thread steel rolling as shown in figure 1, including roll table and the trailing arm that weighs, wherein, the trailing arm 3 that weighs includes a plurality ofly, and a plurality of trailing arms 3 that weigh are along the even interval arrangement of 1 direction of operation of roll table, still include: the horizontal telescopic unit sets up 1 end of roll table, horizontal telescopic unit's telescopic link end-to-end connection has the dog 7 that is used for blockking the blank, and first hot metal detector 5 sets up the middle part of roll table 1, second hot metal detector 6 sets up the end of roll table 1, and is located before the horizontal telescopic unit.
