Abstract
The utility model discloses a stop guide plate for a wedge cross rolling mill, wherein a plurality of nicks are arranged at one side of the stop guide plate at intervals; each nick is provided with an idler wheel; and the idler wheels are connected with the stop guide plate through a pin shaft. In the process of working, a rolled part is fed into the middle of a die and the stop guide plate; then, equipment begins to start; the rolled part rotates along the die so as to be deformed radially and axially; the part having the maximum diameter of the rolled part is contacted with the idler wheels; the idler wheels also rotate around the pin shaft along with rotation of the rolled part; therefore, friction resistance is reduced; furthermore, the part having the maximum diameter of the rolled part contacted with the idler wheels cannot be scraped by the stop guide plate; therefore, the quality of the rolled part is ensured.
Description
Technical field
The utility model relates to a kind of cross wedge rolling machine, particularly a kind of backgauge guide plate for cross wedge rolling machine.
Background technology
Cross wedge rolling is a kind of multidiameter class part forming new technology, its basic principle is: the bar after will heating is sent in the middle of two homodromal moulds with the wedge shape projection, bar is under the effect of wedge shape mould, do the gyration reverse with mould, bar generation radial compression is out of shape and is extended axially distortion simultaneously, thus shaping ladder axial workpiece.This technology is mainly for the production of large in batches axial workpiece, comprise: the axial workpieces such as automobile, gear box of tractor one axle, two axles, jackshaft, back axle bevel gear shaft, engine cam, all kinds of motor shafts, cross wedge rolling technique technique has efficiently, low consumption, the characteristics such as energy-conservation, is the advanced technology of producing axial workpiece.
The effect of backgauge guide plate is the process unit that keeps rolled piece stable rotation in the space that limits in the cross wedge rolling, is to guarantee normally stable important device of carrying out of cross wedge rolling forming technique.The backgauge guide plate of cross wedge rolling is an independent plate at present, and the local frictional resistance power that contacts with workpiece is very large.
The present situation of present cross wedge rolling backgauge guide plate:
In the operation of rolling of axial workpiece, send in the middle of mould and the backgauge guide plate after the bar heating, leaning on the backgauge guide plate with original maximum gauge place begins to rotate, along with bar generation radial compression distortion with extend axially distortion, bar part stepped diameters diminishes, but the maximum gauge place that does not have distortion is leaning on the backgauge guide plate always and is rotating, and frictional resistance is very large, is easy to the scratch workpiece or the backgauge guide plate is caused damage.
Solving at present axial workpiece maximum gauge place is to strengthen the intensity of backgauge guide plate, polishing backgauge guide plate and workpiece contact position by scratch and the impaired main method of backgauge guide plate.But this can increase cost undoubtedly, increases operation.
The utility model content
The utility model has overcome above-mentioned the deficiencies in the prior art, and a kind of backgauge guide plate that is difficult for scratch, damage is provided.
The technical solution of the utility model is achieved in that
The backgauge guide plate that is used for cross wedge rolling machine is interval with a plurality of breach in a side of backgauge guide plate, is equipped with roller in each breach, and described roller links to each other with the backgauge guide plate by bearing pin.
As preferably, described bearing pin crosses whole backgauge guide plate.
Adopted the beneficial effects of the utility model of technique scheme to be:
At work, rolled piece is sent in the middle of mould and the backgauge guide plate, then equipment begins to start, and rolled piece begins to occur radial and axial distortion along with mould rotates, maximum gauge place and the roller contact of rolled piece, along with the rotation of rolled piece, roller also and then rotates around bearing pin, thus capable of reducing friction resistance, and with the rolled piece maximum gauge place of roller contact can be by the scratch of backgauge guide plate, thereby guarantee the quality of rolled piece.
Description of drawings
Fig. 1 is working state schematic representation of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is as follows:
Embodiment: a kind of backgauge guide plate for cross wedge rolling machine, as shown in Figure 1, be interval with a plurality of breach 5 in a side of backgauge guide plate 1, in each breach 5, be equipped with roller 2, described roller 2 links to each other with backgauge guide plate 1 by bearing pin 3.For the ease of installing, described bearing pin 3 crosses whole backgauge guide plate 1.
At work, rolled piece 4 is sent in the middle of mould and the backgauge guide plate, then equipment begins to start, and rolled piece 4 begins to occur radial and axial distortion along with the mould rotation, maximum gauge place and the roller contact of rolled piece 4, along with the rotation of rolled piece, roller 2 also and then rotates around bearing pin, thus capable of reducing friction resistance, and with the rolled piece maximum gauge place of roller contact can be by the scratch of backgauge guide plate, thereby guarantee the quality of rolled piece.
Claims (2)
1. be used for the backgauge guide plate of cross wedge rolling machine, it is characterized in that: the side at the backgauge guide plate is interval with a plurality of breach, is equipped with roller in each breach, and described roller links to each other with the backgauge guide plate by bearing pin.
2. the backgauge guide plate for cross wedge rolling machine according to claim 1, it is characterized in that: described bearing pin crosses whole backgauge guide plate.
