Technical Field
The utility model belongs to the technical field of auto-parts, especially, relate to a mandrel forging.
Background
A forging is a workpiece or a blank obtained by forging and deforming a metal blank. The mechanical properties of the metal blank can be changed by applying pressure to the metal blank to generate plastic deformation. The forging is divided into cold forging and warm forging and hot forging according to the temperature of the blank during processing. Cold forging is generally conducted at room temperature, and hot forging is conducted at a temperature higher than the recrystallization temperature of the metal ingot. The metal looseness and holes can be eliminated through forging, so that the mechanical property of the forging is improved.
The existing mandrel forging still has the following defects: in the subsequent processing process, the fixing and positioning of the workpiece are inconvenient; and the connecting part of the conical body and the flange plate is easy to break, so that the service life of the flange plate is influenced.

The utility model aims at providing a simple structure, be convenient for carry out follow-up processing, improve its bulk strength and improve life's dabber forging to it, especially be fit for being used in automobile speed change mechanism's transmission.
The technical scheme of the utility model is that: a mandrel forging comprises a conical body and a flange plate, wherein the conical body is connected with the flange plate through a reinforcing body, a plurality of annular grooves are sequentially arranged on the circumferential outer side of the conical body from top to bottom, the annular grooves are flared, the width of a notch of each annular groove is larger than that of each groove, an upper blind hole which is sunken towards a large end is formed in the small end of the conical body, the large end of the conical body is coaxially connected with the flange plate, a plurality of protruding cylinders are arranged on the flange plate and far away from the conical body, fixing grooves which are towards the grooves of the flange plate are formed in the outer sides of the protruding cylinders, a fixing area is formed by the plurality of protruding cylinders below the flange plate, the reinforcing body comprises a trapezoidal body which is hollow, reinforcing ribs are arranged in the trapezoidal body, and the short edges of the trapezoidal body are connected with the large end of the conical body, the upper edge end of the trapezoid body is connected with the upper surface of the flange plate.
Furthermore, the conical body, the reinforcing body and the flange are of an integrated structure.
Furthermore, the upper blind hole is an oval blind hole.
Further, the cross section of the annular groove is arc-shaped.
Further, the fixing area is a conical area or a square area.
Furthermore, the side of the flange plate, which is far away from the conical body, is provided with anti-skid grains.
Furthermore, the reinforcing ribs are reinforcing steel bars.
The utility model has the advantages and positive effects that: by adopting the technical scheme, the arranged reinforcing body improves the integral strength of the mandrel forging and improves the quality of the mandrel forging; the upper blind hole, the lower blind hole and the fixing groove are arranged, so that the axial positioning of the fixing groove is convenient during later processing; the annular groove is convenient for circumferential positioning.

Detailed Description
As shown in figure 1, the technical scheme of the utility model is a mandrel forging, which comprises a conical body 1 and a flange 2, wherein the conical body 1 is connected with the flange 2 through a reinforcing body 3,
a plurality of annular grooves 8 are sequentially arranged on the circumferential outer side of the conical body 1 from top to bottom, the annular grooves 8 are in a flaring shape, the width of the groove opening of each annular groove 8 is larger than that of the groove body, the small head end of the conical body 1 is provided with an upper blind hole which is sunken towards the large head end, the large head end of the conical body 1 is coaxially connected with the flange plate 2,
a plurality of protruding cylinders 5 are arranged on the flange 2 far away from the conical body 1, a fixing groove 6 facing the groove of the flange 2 is arranged at the outer side end of each protruding cylinder 5, a fixing area 7 is formed by the plurality of protruding cylinders 5 below the flange 2,
the reinforcing body 3 comprises a trapezoid body, the trapezoid body is hollow, a reinforcing rib is arranged in the trapezoid body, the short side end of the trapezoid body is connected with the large end of the conical body 1, and the upper side end of the trapezoid body is connected with the upper surface of the flange 2.
In this embodiment, the conical body 1, the reinforcement body 3 and the flange 2 are an integral structure.
In this embodiment, the upper blind hole 4 is an elliptical blind hole.
In this embodiment, the fixing region 7 is a tapered region or a square region.
In this embodiment, the side of the flange plate 2 away from the conical body 1 is provided with anti-skid grains.
In this embodiment, the annular groove 8 has an arc-shaped cross section.
In this embodiment, the reinforcing ribs are reinforcing steel bars.
In this embodiment, the protruding column 5 and the flange 2 are integrally formed.
