The objective table 8 makes of metal material, is cylindrical-shaped structure, is equipped with one the in 8 upper surface of objective table Second ring outer 80, the circumferencial direction in the described second annular outer 80 are uniformly provided with two groups of cylindrical body through-holes, circle described in every group Cylinder through-hole arranges four the second cylindrical body through-holes 801 in rectangular layout by two rows two and forms, for assigning the screw rod 3, with The bearing block 6 carries out positioning assembling；Four are along the circumferential direction uniformly provided in the outer ring surface upper end of the described second annular outer 80 A second key mapping hole 802；Four the second key mappings hole 802 is corresponded with four first key mappings hole 103, and described second Key mapping hole 802 can make up a complete key mapping with adjacent first key mapping hole 103 and cheat, for placing the key 7.

The bearing block 6 makes of metal material, and the bearing block 6 is convex shape symmetrical structure, along the bearing block 6 Axis is equipped with a cylinder bore hole, and for placing the rolling bearing 4, two bearing blocks 6, which carry out cooperation for one group, to be made With；It is respectively equipped with a cylindrical body through-hole on two insteps of the bearing block 6, for assigning the screw rod 3.

The roll 5 makes of metal material, is made of the roll neck at the body of roll and both ends, for conveying high temperature steel member；It is described The roll neck at both ends can be inserted into respectively one group described in the rolling bearing 4 in bearing block 6.

The rolling bearing 4, the key 7, the screw rod 3 and the nut 2 are standard component.

The utility model has the following characteristics:

Since the present apparatus uses a pedestal, an objective table, six rolls, 12 bearing blocks, 13 axis of rolling Hold, four pieces of keys, 24 screw rods and 24 nuts form, material is common and easy to process, therefore, the production of the present apparatus Advantage of lower cost；

Since the inner ring surface of pedestal and the outer ring surface of objective table are uniformly provided with four the first key mapping holes in circumferencial direction respectively It is cheated with the second key mapping, adjacent first key mapping hole and the second key mapping hole can make up a complete key mapping hole, often One piece of key is respectively installed in a key mapping hole, therefore, the rotating accuracy of the present apparatus is relatively high；

Since rolling bearing is mounted in the cylinder bore hole of pedestal, the objective table for being inserted into rolling bearing inner ring can be light Realization return in the horizontal plane turn 90 degrees, 180 degree or 270 degree, therefore, the operating process of the present apparatus is by a relatively simple；

By the utility model patent device, the purpose turned round on roller-way to high temperature steel member is realized, there is life Produce feature at low cost, that rotating accuracy is high and easy to operate.

Assembling process: as shown in Figures 1 to 6, the pedestal 1 is stably placed on ground first, then by an institute Rolling bearing 4 is stated to be mounted in the cylinder bore hole 102 of the pedestal 1, it so, can be by a rolling bearing 4 It is assembled with the pedestal 1.

Then a rolling bearing 4 is respectively installed in the cylinder bore hole of each bearing block 6, it then will be each The both ends of the roll 5 be inserted into one group respectively described in two rolling bearings 4 being installed of bearing block 6, so, can Six rolls 5 to be assembled with bearing block 6 described in six groups.

Then bearing block 6 described in one group of the roll 5 will be installed be placed on the annular outer of the pedestal 1, so This is organized to cylindrical body through-hole centering described in one group of the four cylindrical body through-holes and the pedestal 1 on the bearing block 6 afterwards, then The screw rod 3 is respectively assigned in each cylindrical body through-hole in, then in each twist-on of the other end of the every screw rod 3 One nut 2；So, bearing block 6 and the pedestal 1 described in one group can be subjected to positioning assembling, with same Bearing block 6 and the pedestal 1 described in other three groups can be carried out positioning assembling by method.

Then the objective table 8 is inserted into the inner ring of the rolling bearing 4 in the cylinder bore hole 102；Then will Bearing block 6 described in two groups of residue of the roll 5 is installed and the objective table 8 carries out positioning assembling.

Then the objective table 8 is rotated, guarantees that 103 centerings are cheated with first key mapping in the second key mapping hole 802, then Four pieces of keys 7 are separately mounted in four complete key mapping holes, so, package unit is completed, and can be put into It uses.

Use process: it before the assembled present apparatus is placed in the roller-way of rolling mill first, should ensure that on the objective table 8 Then the roller-way axis centering of roller-way axis and the rolling mill that two rolls 5 are constituted is transported high temperature steel member by roller-way It is sent on two 5 passes of roll of the objective table 8, and is parked；Then by four pieces of keys 7 from four key position holes In take out one by one, then the objective table 8 is rotated to, so, the objective table 8 and the height by scheduled angle Warm steel part has turned round a scheduled angle jointly.

Embodiment 1: the objective table 8 is rotated by 90 ° in the direction of the clock, then each in the key position hole in One piece of key 7 is installed, the roll 5 on the objective table 8 is then rotated, then high temperature steel member is pierced by the left of the present apparatus, real 90 degree of revolutions of existing high temperature steel member, as shown in Figure 4.

Embodiment 2: rotating 180 degree for the objective table 8 in the direction of the clock, then each in the key position hole in One piece of key 7 is installed, then rotates the roll 5 on the objective table 8, then high temperature steel member is pierced by front side of the present apparatus, edge Backtracking realizes the 180 degree revolution of high temperature steel member, as shown in Figure 2.

Embodiment 3: rotating 270 degree for the objective table 8 in the direction of the clock, then each in the key position hole in One piece of key 7 is installed, the roll 5 on the objective table 8 is then rotated, then high temperature steel member is pierced by the right side of the present apparatus, real 270 degree of revolutions of existing high temperature steel member, as shown in Figure 4.
