Description

Water stop device for opener

The invention relates to a steel processing device, in particular to a water blocking device for an opener.

During the steel processing, the steel material heated by the heating furnace is hot rolled by an opener to produce a H-shaped steel embryo.

A prior art opener includes two shaft seats spaced apart in a left-right direction, an upper roller shaft pivotally connected between the shaft seats in the left-right direction and rotatable relative to the shaft seats, and a left and right The direction is pivotally connected between the axle seats and is rotatable relative to the axle seats and disposed on the lower roller shaft, the upper support bars, and the lower support bars below the upper roller shaft. The upper support rods are spaced apart from each other on opposite sides of the upper roll shaft in a front-rear direction and are connected between the equal-axis seats. The lower support rods are spaced apart from each other on opposite sides of the lower roll shaft in the front-rear direction and are connected between the equal-axis seats. The heated steel material is rolled forward between the upper roller shaft and the lower roller shaft in the front-rear direction and processed. The upper support rods and the lower support rods can prevent the steel from being warped during the machining process and inadvertently collide with the upper roller shaft or the lower roller shaft.

In this process, cooling water is sprayed on the upper roller shaft and the lower roller shaft to absorb heat energy to keep the upper roller shaft and the lower roller shaft from softening or being damaged due to excessive temperature. However, the cooling water sprayed on the upper roller shaft flows down to the processed steel material due to gravity, which causes the upper half of the steel material to receive cooling water to accelerate cooling and be different from the cooling rate of the lower half. Different cooling rates can result in uneven texture of the finished product, affecting the quality of the product.

Accordingly, it is an object of the present invention to provide a water retaining device for an opener that can prevent cooling water from flowing to a steel material in processing and thereby improve product quality.

The inner side wall, the connecting wall and the outer side wall together define a mounting groove having an opening facing downward and adapted to receive a portion of the support rod.

The blocking group of each stopping unit has a drainage member extending in the left-right direction and connected to the fixing seats, and an abutting member connected to the drainage member. The drain has an upper arc portion and a lower arc portion connected below the upper arc portion. The upper arc portion and the lower arc portion are curved in a cross section in the left-right direction and collectively define a first drainage groove whose opening faces the other stopping unit and faces upward. The abutting member has a connecting portion connected to the lower arc portion and an abutting portion opposite to the connecting portion. The abutment extends toward the other stop unit and is deflected upwardly and has an abutment edge that cooperates with the shape of the upper roller shaft. Due to gravity, the abutting member is pressed down such that the abutting edge is in close contact with the surface of the upper roller shaft. When the cooling water is sprayed from above the upper roller shaft, the cooling water is blocked by the abutting member without flowing in. The first drainage groove is guided under the upper roller shaft and discharged from both sides in the left and right direction by the first drainage groove.

The lower arc portion 512 also has a plurality of through holes 515 communicating with the second drain groove 561.

In the present embodiment, the abutting members 52 are made of a mixture of rubber and polyurethane, but may be other soft wear-resistant materials, and are not limited to such materials.

During the processing, the upper roller shaft 12 rotates with the lower roller shaft (not shown) located below and rolls the steel material underneath, and the cooling water for cooling the upper roller shaft 12 is sprayed from above the upper roller shaft 12. To cool the upper roller shaft 12. Due to gravity, the abutting members 52 drive the corresponding fixing seats 3 to be biased relative to the corresponding support rods 13. The abutment members 52 are thus depressed against the upper roller shaft 12 such that the abutment edges 523 remain adhered to the surface of the upper roller shaft 12 while rotating. The cooling water sprayed from above the upper roller shaft 12 is stopped by the abutting members 52 without flowing to the processed steel material. The cooling water flows along the stopper group 5 and is guided into the first drainage groove 514 and is discharged by the first drainage groove 514 in both sides of the left-right direction D1, thereby producing an effect of dispersing the water flow.

Since the water flow does not flow to the steel in the process, the steel does not have the problem of different cooling rates as described in the prior art by receiving the cooling water, so that the finished product has a uniform texture and improves product quality. Since the water flow does not flow to the steel being processed, the temperature of the steel can be maintained at a relatively high temperature, so the temperature requirement for the steel before being processed by the opener is relatively lowered. That is to say, the heating furnace can heat the steel to a lower temperature, which can reduce energy consumption and produce a cost-saving effect.

Without the mounting member 4, the abutting members 52 can still drive the corresponding fixing base 3 to be biased relative to the corresponding supporting rod 13. However, by matching the top surface 41 of the mounting member 4 with the corresponding mounting groove 35, a better biasing effect can be produced.

In addition, since the abutting members 52 are pressed by gravity, in order to prevent the device from being unstable due to the excessive angle of the abutting members 52, the first set screws 34 and the respective mounting slots are inserted. Within 35, it is placed against the corresponding support rod 13 to limit the angle of the deflection by the structure. The second set screws 56 penetrate into the respective mounting slots 35 and abut against the top surface 41 of the mounting member 4 to lift the frictional force with the mounting member 4.

In summary, the water retaining device of the opener of the present invention blocks the cooling water by the abutting members 52 of the stopping units 2 and is discharged by the first draining grooves 514 to prevent the cooling water from flowing into the processing. The steel material, and thus the quality of the product, can indeed achieve the object of the present invention.
