Description

Technical Field

[0001] The utility model relates to a graphite bracket device and belongs to the field of industrial processing. Background Art

[0002] H112 state pipes are large-diameter, small-wall-thickness pipes. During the production and extrusion process, such pipes need to be lifted and transported by rollers. However, due to the aging of the rollers, the contact between the pipes and the aged rollers at high temperatures is prone to cause pits and flat defects. The thin-walled pipes produced at this time cannot meet the appearance and dimensional tolerance requirements and need to go through a shaping process, which increases the risk of pipe scrapping and reduces efficiency and yield rate. Utility Model Content

[0003] The technical problem to be solved by the utility model is that in the prior art, during the extrusion process of the pipe, when the high-temperature pipe contacts the aged roller, pits and flat defects are easily caused.

[0004] In order to solve the above technical problems, a technical solution provided by the utility model is:

[0005] A graphite bracket device comprises an upper support plate and a lower support plate, wherein the upper support plate and the lower support plate are connected together by a support column, the upper support plate is provided with a limit groove which passes through from top to bottom, the limit groove is provided with a limit column which can reciprocate in the limit groove, a graphite block is placed on the upper end surface of the upper support plate near the limit groove, and the upper end surface of the graphite block is provided with an arc groove which matches the shape of a pipe to be supported.

[0006] The limit block is arranged in the advancing direction of the pipe, and the graphite block is arranged behind the limit block. When the graphite block lifts the pipe, the limit block blocks the graphite block in front of the graphite block to prevent the graphite block from moving forward with the pipe.

[0007] The upper end of the limiting column extends out of the upper end surface of the limiting groove to facilitate limiting the graphite block. The lower end of the limiting column is arranged on the lower support plate, and a side wing plate with a first bolt hole is arranged on the side surface of the lower end of the limiting column.

[0008] The side wing plates are fixedly connected to the limiting columns and are arranged at an angle of 90 degrees.

[0009] Or the side wing plate is hingedly connected to the limiting column.

[0010] There are two limit columns, and each limit column is also provided with a side wing plate. At least four pairs of second bolt holes are provided on the lower support plate on the horizontal line corresponding to the side wing plate, and the second bolt holes correspond to the first bolt holes up and down. The limit column is fixed to the lower support plate by the first bolt hole and the second bolt hole using the first bolt hole.

[0011] After the bracket is placed at the predetermined position, a graphite block matching the outer dimensions of the pipe is placed on the upper end surface of the upper support plate so that the graphite block is close to the limiting groove, and then two limiting columns are moved in the limiting groove so that one of the limiting columns is located at a position corresponding to the left end of the graphite block and the other limiting column is located at a position corresponding to the right end of the graphite block, and they are fixed to limit the graphite block. Note that the limiting block cannot be located at a position corresponding to the arc groove of the graphite block, because in this case, the protruding limiting block will touch the pipe and cause damage to the pipe.

[0012] Different graphite blocks are provided with different sizes. When the outer diameter of the tube changes, graphite blocks of different sizes can be replaced according to the change in the size of the tube.

[0013] The graphite blocks have different sizes. When limiting the graphite blocks of different sizes, the limiting blocks need to be in different positions. Therefore, at least four pairs of second bolt holes are provided to facilitate fixing the limiting blocks in different positions, and the scope of use is wide.

[0014] The upper support plate is provided with upper bolt holes penetrating from top to bottom at four corners, and the lower support plate is provided with lower bolt holes penetrating from top to bottom at positions corresponding to the upper bolt holes.

[0015] The support column is a long bolt with two nuts. The long bolt passes through the lower end surface of the lower bolt hole and comes out from the upper end surface of the upper bolt hole. A nut is provided on the upper end surface and the lower end surface of the long bolt. The two nuts fix the upper support plate on the long bolt.

[0016] Long bolts are used as support columns to facilitate adjustment of the distance between the upper support plate and the lower support plate so that it can adapt to pipes at different heights from the ground.

[0017] In the above device, the upper support plate, the lower support plate and the limiting column are all assembled by using steel plates.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model uses a graphite support and a graphite block to hold up the pipe during extrusion, so that the extruded pipe fits closely with the graphite, avoiding pits and flat defects caused by the contact of the pipe with the roller under high temperature. The pipe contacts the roller after cooling down, so that the produced thin-walled pipe meets the appearance and dimensional tolerance requirements, eliminating the shaping process and the risk of scrapping, and improving efficiency and yield rate.

[0020] 2. In the utility model, the graphite blocks are provided with different sizes, and the arc grooves on the graphite blocks are also provided with different sizes, which can adapt to the lifting of pipes of different sizes and has a wide range of applications.

[0021] 3. The utility model is provided with a limiting groove with a limiting column and a plurality of second bolt holes, which facilitates the limiting fixation of limiting blocks of different sizes at different positions, which is simple and convenient.

The upper support plate 1 is provided with upper bolt holes 4 extending vertically at four corners, and the lower support plate 2 is provided with lower bolt holes extending vertically at positions corresponding to the upper bolt holes 4.

[0035] Each pair of corresponding upper bolt holes 4 and lower bolt holes is connected and fixed by a long bolt 3 , and there are four long bolts 3 in total, and each long bolt 3 is provided with two nuts 5 .

[0036] The long bolt 3 passes through the lower end surface of the lower bolt hole and comes out from the upper end surface of the corresponding upper bolt hole 4, and a nut 5 is provided on the upper end surface and the lower end surface of the upper support plate 1 on the long bolt 3.
