Abstract
The utility model discloses a material blocking plate for shaft part forging rolling. The material blocking plate for shaft part forging rolling comprises fixed plates, wherein a forwards-protruding circular arc portion is arranged on the front side of each fixed plate, a plurality of grooves which are evenly distributed are formed in the circular arc portions, rollers are arranged in the grooves respectively, and fixing hinge pins penetrate through the rollers arranged in the grooves so that the rollers can be connected with the fixed plates. The material blocking plate for shaft part forging rolling solves the problem that an existing material blocking plate is prone to scratches, the design is simple, and the structure is reasonable; due to the facts that a possible contact surface between the material blocking plate and a workpiece, and a possible contact surface between the material blocking plate and a die are designed to be of a circular-arc shape, and the rollers are distributed in the circular arc portions respectively, sliding friction is replaced by rolling friction, loss of the material blocking plate is effectively avoided, and the service life of the material blocking plate for shaft part forging rolling is prolonged.
Description
Technical field
The utility model relates to Machining of Shaft-type Parts equipment technical field, specifically belongs to a kind of axle class part forging rolling striker plate.
Background technology
In the operation of rolling of axial workpiece, after bar heating, send in the middle of mould and backgauge guide plate, with original maximum gauge place, leaning on backgauge guide plate starts to rotate, along with bar generation radial compression distortion with extend axially distortion, bar part stepped diameters diminishes, but the maximum gauge place that there is no distortion is leaning on backgauge guide plate always and is rotating, and frictional resistance is very large, is easy to scratch workpiece or backgauge guide plate is caused to damage.Solving at present axial workpiece maximum gauge place is to strengthen intensity, polishing backgauge guide plate and the workpiece contact position of backgauge guide plate by scratch and the impaired main method of backgauge guide plate.But this can increase cost undoubtedly, increase operation.
Utility model content
The purpose of this utility model has been to provide a kind of axle class part forging rolling striker plate, solved the problem that damage is scraped in the easy scratch of existing striker plate, simplicity of design, rational in infrastructure, by striker plate and workpiece and mould likely contact-making surface be designed to circular arc, circular arc is provided with roller bearing in distributing, and by rolling friction, replaces sliding friction, effectively avoid striker plate loss, service life.
The technical solution adopted in the utility model is as follows:
A kind of axle class part forging rolling striker plate, comprise fixed head, described fixed head front side has the circular arc portion protruding forward, and circular arc portion has the groove of a plurality of even minute, in groove, be provided with roller bearing, the roller bearing in a plurality of grooves has fixedly pivot pin through being connected with fixed head.
Described roller bearing face and circular arc portion cambered surface are tangent, and circular arc portion front side is opening.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model by striker plate and workpiece and mould likely contact-making surface be designed to circular arc, circular arc is provided with roller bearing in distributing, and by rolling friction, replaces sliding friction, effectively avoids striker plate loss, service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of axle class part forging rolling striker plate, comprise fixed head 1, fixed head 1 front side has the circular arc portion 2 protruding forward, circular arc portion 2 has the groove 201 of a plurality of even minute, is provided with roller bearing 3 in groove 201, and the roller bearing 3 in a plurality of grooves 201 has fixedly pivot pin 4 through being connected with fixed head 1,3 of roller bearings are tangent with circular arc portion 2 cambered surfaces, and circular arc portion front side is opening.Send into workpiece 5 and between top and bottom rolls 6, carry out forging rolling, striker plate and workpiece and mould likely contact-making surface are designed to circular arc, and circular arc is provided with roller bearing in distributing, and by rolling friction, replace sliding friction, effectively avoid striker plate loss, service life.
