Abstract
The utility model relates to a crankshaft nitriding rack which is provided with a rectangular supporting framework; the supporting framework consists of upright posts, transverse connecting plates and two lateral connecting beams, wherein the upright posts and the transverse connecting plates are processed and manufactured by angle irons; four corners of the supporting framework are fixed in material tray positioning holes by positioning columns; and a bending support plate with three supporting positions is arranged on each transverse connecting beam. Each bending support plate is in a wave-shaped structure formed by bending and connecting a steel plate; and an included angle formed by steel plates on the two sides of each supporting position is 90 DEG. In the crankshaft nitriding rack, the space of material trays can be reasonably utilized under the condition that other facilities and the process of a crankshaft nitriding production line are not changed, the purpose that three crankshafts are stably placed one each layer of material rack is realized and a great amount of crankshafts can be assembled, thereby improving the production efficiency.
Description
Technical field
The utility model relates to a kind of bent axle thermal treatment bracing or strutting arrangement, specifically a kind of bent axle nitrogenize bin.
Background technology
We know that thermal treatment bin commonly used mostly is flatwise, places formula or suspension type vertically.What the continous way nitempering furnace used is stepped start-stop system bent axle nitrogenize feeding rack, and these how tame at home engine works of stepped start-stop system bent axle nitrogenize feeding rack are extensive use of.The flatwise nitrogenize bin that adopts is the traditional design thinking, is generally 2 layered material framves, puts 2 bent axles for every layer, and bin horizontal support bent axle also needs balance weight iron, is symmetry arrangement, and production efficiency is lower.Generally be according to designing during existing bin design with the maximum rotating diameter, for preventing to touch between workpiece, the bent axle symmetry arrangement, space availability ratio is low, and production efficiency is on the low side.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple and reasonable for structure, under the prerequisite that does not change nitrogenize apparatus for production line and other technology, rationally utilize the space, built-up crankshaft quantity is many, the bent axle nitrogenize bin of enhancing productivity greatly.
The technical scheme in the invention for solving the above technical problem is: a kind of bent axle nitrogenize bin, it is provided with a rectangle support frame, support frame is made up of column, cross connecting plate, side tie-beam, column, cross connecting plate are by the angle bar processing and fabricating, four root post bottoms have been welded to connect retaining plate respectively, two cross connecting plates are fixedly mounted on the retaining plate respectively, the retaining plate downside is provided with reference column, it is characterized in that: be respectively equipped with a bending back up pad with three support levels on two cross connecting plates.
The Wave-shaped structural of three support levels that bending back up pad described in the utility model connects to form for the steel plate bending, the steel plate angle of each support level both sides are 90 degree.
The utility model is owing to be respectively equipped with a bending back up pad with three support levels on two cross connecting plates, can support on two bending back up pads and place 3 bent axles, during use, four jiaos of support frames are fixed in the charging tray pilot hole by reference column, the utility model can also be arranged to two-layer up and down as required, upper strata bin and lower floor's bin are by four stud location, lower floor's bin reference column directly is positioned to prevent that the upper strata bin is with respect to lower floor's bin in process of production in the existing installation stepping charging tray pilot hole, about lower floor's bin occurs with respect to charging tray and front and back jump.Against existing technologies, the utility model changes horizontal symmetrical support bent axle in the prior art, every bent axle adopts suitable angle to support, realize the steadily purpose of three bent axles of placement of every layered material frame, with the space utilization maximization, under the prerequisite that does not change other facility of bent axle nitrogenize production line and technology, rationally utilize the charging tray space, built-up crankshaft quantity is many, has improved production efficiency greatly.

Embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of bent axle nitrogenize bin, it is provided with a rectangle support frame, support frame is made up of column 1, cross connecting plate 5, side tie-beam 3, side tie-beam 4, column 1, cross connecting plate 5 are by the angle bar processing and fabricating, and four root posts, 1 bottom has been welded to connect 6, two cross connecting plates 5 of retaining plate respectively and has been fixedly mounted on respectively on the retaining plate 6, side tie-beam 3,4 is connected to upper and lower between two columns, constitutes the rectangle support frame.Be provided with reference column 7 below four root posts, the 1 bottom retaining plate 6, four jiaos of support frames are fixed in the charging tray pilot hole by reference column 7.Bent axle nitrogenize charging tray is the parts in the existing stepped start-stop system bent axle nitrogenize equipment.
Characteristics of the present utility model are: be respectively equipped with a bending back up pad 2 with three support levels on two cross connecting plates 5.The Wave-shaped structural of three support levels that described bending back up pad 2 connects to form for the steel plate bending, the steel plate angle of each support level both sides are 90 degree.Like this, can support 3 bent axles of placement on two bending back up pads 2.Four jiaos of support frames are fixed in the charging tray pilot hole by reference column 7.
The utility model can also be arranged to two-layer up and down as required, and its lower floor's bin as shown in Figure 3.Its essentially consist, structure are identical with upper layer material shelf structure shown in Figure 1.Different is the bending position difference of bending back up pad 2, wherein three support levels and upper strata shown in Figure 1 bin complementation.The double-deck combination of the utility model synoptic diagram as shown in Figure 4, upper strata bin and lower floor's bin are by four stud location, lower floor's bin reference column directly is positioned in the existing installation stepping charging tray pilot hole, jumps before and after preventing to reach about the upper strata bin occurs with respect to charging tray with respect to lower floor's bin, lower floor's bin in process of production.Like this, every bent axle adopts suitable angle to support, and realizes the steadily purpose of three bent axles of placement of every layered material frame, with the space utilization maximization, under the prerequisite that does not change other facility of bent axle nitrogenize production line and technology, rationally utilize the charging tray space, built-up crankshaft quantity is many, has improved production efficiency greatly.
