Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the utility model is now described with reference to the accompanying drawings.

As shown in Fig. 1 and Fig. 2 and Fig. 3, the fixed-to-length baffle device according to the embodiment of the present invention includes: a cylinder 20, a connecting rod 22, a support 24, a pendulum shaft 21, and a stopper 23;

Described cylinder 20, is arranged on the car body 16 of dolly of fixed length, for example cylinder is fixed on the car body 16 of dolly of fixed length by cylinder bracket 26; Cylinder 20 connects gas storage tank, and gas storage tank is for example arranged on the car body, The volume of the gas storage tank is, for example, 2m ³ , the cylinder 20 and the gas storage tank provide power, and the compressible characteristics of the gas are used to achieve a cushioning effect; the rodless chamber of the cylinder is the working chamber. When the cylinder has a rod chamber to pass compressed air, the head Swing backwards, this structure can avoid friction with the steel plate bonding surface when the stop head is lifted, and realize that the position of the fixed-length steel plate remains unchanged; the junction point of the cylinder 20 and the connecting rod 22 is arranged at the same height as the stop head, The cylinder adopts the tail swing shaft installation method. The advantages of this layout structure are reflected in: the cylinder has a strong ability to withstand the impact force of the steel plate; the mechanism has a large swing space; the stroke of the cylinder is short and the lifting height of the stopper is high;

The support 24 is fixedly connected to the vehicle body 16;

The connecting rod 22 has three ends, respectively: the first end of the connecting rod 22, the second end of the connecting rod 22 and the third end of the connecting rod 22, the first end of the connecting rod 22, the second The line connecting the end and the third end forms a triangle;

The first end of the connecting rod 22 is hinged with the cylinder 20 through a pin 29, and the second end of the connecting rod 22 is hinged with the support 24 through the swing shaft 21;

The blocking head 23 is connected to the third end of the connecting rod 22 and is used to block the plate or steel plate 60 . As shown in Figure 2, when the plate or steel plate 60 hits the stopper 23 along the running direction 70, the impact force is transmitted to the cylinder 20 through the stopper 23, and the impact is absorbed by the cylinder 20. When the impact force of the steel plate is too large and the stopper 23 retreats , the active force of the cylinder 20 is enough to push the steel plate and the stopper 23 back to the initial fixed-length position of the stopper 23, and the stroke of the cylinder is, for example, 400mm, so that the steel plate finally stops at the ideal fixed-length position; this structure effectively utilizes the cylinder 20 machine The cushioning characteristics of the gas storage tank with a volume of ^2m3 , combined with the structural layout and force analysis, it is calculated that the force of the cylinder is greater than the friction force of the steel plate on the roller table, so that the steel plate stops at the ideal fixed length position, and at the same time The impact of the steel plate on the support and the car body is reduced, thereby ensuring the stability of the car body and improving the position accuracy of the car body.

Further, the balance shaft is an eccentric shaft. As shown in Figure 1, the eccentricity d of the pendulum shaft is, for example, 5 mm, so the installation position of the stopper can be adjusted in height within the range of 0 to 10 mm through the (eccentric) pendulum shaft. Therefore, the height of the installation position of the baffle lifting mechanism is adjustable. This design structure, on the one hand, can ensure that the distance between the stopper and the roller table is adjusted to the theoretical design value during installation, so as to compensate for the accumulated errors in the manufacturing and installation stages; The deformation of the cover plate after long-term use causes partial interference between the head and the cover of the roller table) flexibly adjust the height and position of the head to avoid the occurrence of interference.

Moreover, the (eccentric) pendulum shaft makes the time for the stopper 23 to return to the blocking position (lower limit position) from the lifted position (upper limit position) shorter than that of the symmetrical pendulum shaft, and the sizing is more timely and accurate. As shown in Figure 2, the maximum height h (from the roller surface of the grooved roll) of the stop head is for example: 120mm, so that the thick plate (thickness > 60mm) that is not cut to length can pass under the stop head without jamming resistance phenomenon.

Further, the lower bottom surface of the stop head is processed into a sawtooth shape, the lower bottom surface of the stop head is alternately arranged with the grooved rollers of the conveying roller table, and the lowest point of the stop head movement track is located directly below the swing shaft, and the stop head When swinging, the center of the circle is aligned with the rightmost end face of the stopper in the vertical direction. This design structure, on the one hand, can ensure that the distance between the stopper and the roller surface and between the stopper and the roller cover is less than the thinnest plate thickness (5mm); On the other hand, it can avoid interference with the roller table or the roller table cover when the stop head is raised.

Further, as shown in FIG. 4 and FIG. 5 , the grooved roller 40 includes: protrusions 400 and grooves 405 between the protrusions, and the bottom of the head has a matching groove containing the protrusions 235.

Further, as shown in FIG. 4 and FIG. 5 , the lower bottom surface of the stop head 23 is processed into a sawtooth shape, and the lower bottom surface of the stop head 23 is alternately arranged with the grooved rollers of the conveying roller table. In other words, the lower bottom surface or bottom 230 of the stop head 23 has a matching groove 235 that accommodates the protruding portion 400 of the grooved roll, and the groove 405 or the grooved portion of the grooved roll is formed between the protruding portions 400 of the adjacent grooved roll , the number of matching grooves 235 is one or more, and the number of matching grooves 235 is equal to the number of grooves 405 or grooved parts of the grooved roller. The shape of the matching grooves 235 is, for example, a rectangular open groove, which is convenient for processing; The grooved rollers of the conveying roller table are arranged in a staggered manner, which prevents the steel plate from penetrating into the bottom surface of the head when the head is above the roller table.

Further, as shown in FIG. 4 and FIG. 5 , the height difference t1 between the lower bottom surface 230 of the stopper head (lowest bottom surface of the stopper head) and the bottom surface 430 of the groove 405 is 2-4 mm, for example, 3 mm. The height difference t2 between the lower bottom surface 230 of the stopper head (the lowest surface of the stopper head) and the top surface of the cover plate is 2-4 mm, for example, 3 mm. In this way, the gap between the stop head and the roller table and the gap between the stop head and the cover plate are less than 5mm, for example, 3mm, so that the thinnest medium-thick plate cannot pass through the gap between the stop head and the roller table, as well as the stop head and the cover plate The gap between them, so as to avoid the phenomenon that the thin plate penetrates into the bottom surface of the stopper.

The depth m of the groove 405 of the grooved roll is 25mm. The depth k of the matching groove 235 of the stopper is 25 mm, and the upper side of the grooved roller of the conveying roller table is covered with a cover plate 50, and the top surface of the cover plate is lower than the highest point of the circumference of the grooved roller 25 mm, that is, the height difference s between the cover plate and the grooved roller is 25 mm, the plate is a medium plate, and the thickness of the plate is 5 to 50 mm.

In the prior art, the height difference between the stop head and the roller table is 4mm, and the roller table cover is lower than the roller table surface (for example, 10mm), so the height difference between the bottom surface of the stop head and the cover plate will be greater than 5mm (for example, 14mm), the utility model’s fixed-length plate thickness range or steel plate thickness range: 5-50mm, that is, the thickness of the thinnest steel plate for medium and thick plates is 5mm. Therefore, when the stopper is above the cover plate, the existing equipment is prone to thin plate wear steel phenomenon. However, in the utility model, the height difference t1 between the lower bottom surface of the stopper head and the groove of the roller table is reduced to 2-4mm, and at the same time, the height difference t2 between the lower bottom surface of the stopper head and the cover plate is ensured to be 2-4mm, which realizes the When the head is above the cover plate, the phenomenon that the steel plate penetrates into the bottom surface of the head is avoided.

Compared with the prior art, the utility model has the following characteristics and advantages:

Avoid interference with steel penetration: the height of the stopper is adjustable, and at the same time, the stopper and the grooved rollers of the conveying roller table are arranged alternately. Interference involves the phenomenon of thin plate piercing steel.

High sizing accuracy: effective use of the cushioning characteristics of the cylinder to make the steel plate finally stop at the ideal sizing position;

The utility model is not only used for measuring medium and thick plates, but also can be widely used in the precise determination of finished plates on medium and thick plate production lines in the metallurgical industry and other plate production lines.

The above descriptions are only illustrative specific implementations of the present utility model, and are not intended to limit the scope of the present utility model. Because the components of this utility model can be combined with each other under the condition of no conflict, any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principles of this utility model shall belong to this utility model.
