Description

Grinding table support and roll grinder equipment

The present invention relates to a grinder apparatus, and more particularly to a grinder seat and roll grinder apparatus.

The hot rolling mill is mainly used to provide various rolls for rolling strips in hot-rolled steel strip plants. In order to meet different needs, a general roll mill and a back roll grinder are usually provided in a general hot rolling mill. Among them, the work roll grinder is mainly used to grind a finishing roll with a bearing housing, while the back roll grinder is used to grind other types of rolls.

Since the back roll grinder needs to grind a plurality of rolls, and the roll diameters or roll neck positions of the various rolls are different, a seat is usually provided in the back roll grinder to support the rolls. Among them, the design of the seat can be divided into two types: the big seat and the small seat. Please refer to FIG. 1 first, which is a schematic diagram showing the use of a large-seat grinding roll for a conventional back roll grinder. In the conventional back roll grinder 100, the large mount 110 is mainly suitable for supporting a roll having a larger roll diameter or a bearingless case, such as a finishing roll, a rough rolling mill (Roughing Mill, RM) back roll, R1 work. Roll, R2 work roll, T1 (NO3) work roll, T4 (NO4) work roll and T5 (NO3) back roll.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is a schematic view showing the use of a small seat grinding roll by a conventional back roll grinder. In the conventional back roll In the grinding machine 100, when the roll 150 of a smaller roll diameter or the finishing roll with a bearing case is to be ground, the large seat 110 must be replaced with the small seat 130. However, the operation procedure and the steps of replacing the large support 110 with the small support 130 or replacing the small support 130 with the large support 110 are quite complicated and take a long time. The back roll grinder must remove the cutting fluid baffle, replace the reversing device, the top center, the fuel injection system, the seat, and the correction roll center, etc., and the operation risk is high. Furthermore, in the process of changing the seat, the staff must use the crane to hang the entire seat, and there are many dangers in hanging the seat with considerable weight, and the long operating time of the crane causes other work. Personnel cannot use the crane effectively.

Accordingly, it is an object of the present invention to provide a grinder seat and roll grinder apparatus that can accommodate different types of rolls and improve the efficiency of use.

According to the above object of the present invention, a grinding machine seat is proposed. This grinding machine seat is suitable for supporting a roll. The grinding machine seat includes a base, a first support portion, a second support portion, a first size adjustment member, and a second size adjustment member. The first support portion and the second support portion are disposed on the base. The first size adjustment member is detachably disposed on the first support portion. The second size adjustment member is detachably disposed on the second support portion.

According to an embodiment of the present invention, each of the first size adjustment member and the second size adjustment member are babbitt adjustment members.

According to another embodiment of the present invention, the roll neck of the roll is supported by the first support surface and the second size adjuster of the first size adjustment member. Second support surface.

According to still another embodiment of the present invention, the first support portion and the second support portion respectively have a first center line and a second center line, wherein the first center line and the second center line respectively extend to the axis of the roll And perpendicular to the axis.

According to still another embodiment of the present invention, the roll is a finishing roll, and the finishing roll further comprises a bearing housing.

According to still another embodiment of the present invention, the above-mentioned grinding machine seat further comprises a support base. A support base is provided on the base to support the bearing housing.

According to the above object of the present invention, a roll grinder apparatus is further proposed. This roll grinder equipment includes a grinder seat, a headstock and a tailstock. The grinding machine seat is suitable for supporting a roll. The grinding machine seat includes a base, a first support portion, a second support portion, a first size adjustment member, and a second size adjustment member. The first support portion and the second support portion are disposed on the base. The first size adjustment member is detachably disposed on the first support portion. The second size adjustment member is detachably disposed on the second support portion. The head seat is placed on one side of the grinding machine seat to drive the roll to rotate. The tailstock is placed on the other side of the grinding machine seat to limit the rolls.

According to an embodiment of the present invention, the roll grinder apparatus described above further includes a suspension device. The suspension device is disposed beside the grinding machine support for suspending the first size adjustment member or the second size adjustment member.

According to another embodiment of the present invention, each of the first size adjustment member and the second size adjustment member has a suspended perforation. Moreover, the suspension device includes a suspension and a pair of movable hooks. The movable hook is arranged on the suspension, And the movable hook can be correspondingly clamped in the hanging perforation of the first size adjustment member or the second size adjustment member.

According to still another embodiment of the present invention, the suspension device further includes a slide rail and an elastic member. The slide rails are connected to the suspension members, and the movable hooks are disposed on the slide rails. The elastic members are disposed between the movable hooks and connected to the movable hooks.

It can be seen from the above that the novel type through the design of the replaceable first size adjusting member and the second size adjusting member enables the grinding machine to support the function of the large seat and the small seat. Thereby, the roll grinding machine of the present invention can grind rolls of various sizes and types without changing the seat of the grinding machine. Since the roll grinder equipment of the present invention does not need to replace the grinder seat, it is possible to avoid the problem that a lot of time is wasted due to the replacement of the seat, the disassembly and assembly of the seat is difficult, the danger is high, and the crane is occupied.

It can be seen from the above that the roll grinding machine of the present invention does not need to use the overhead crane to replace the whole grinding machine seat, but provides the operator to suspend and replace the first size adjusting piece and the second size through the simple operation suspension system. Adjustments can save time and improve operational safety. Thereby, the roll grinding machine of the present invention can support the grinding operation of the rolls of different types and sizes in a short time, and can improve the efficiency of the roll feeding mill to the rolling mill.
