Technical Field

The utility model relates to the technical field of mold, specifically be a assembling die for producing wheel hub forging.

Background

The wheel hub is a cylindrical metal component with the inner contour of the tire supporting the tire and the center of the metal component is arranged on a shaft, and is also called a rim, a steel ring, a wheel and a tire bead. The hub is of various kinds according to diameter, width, molding mode and material. The production process of the wheel hub needs a die, which refers to various dies and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts.

After the former die is used, the problem that a horn mouth appears at the bottom due to uneven thickness and different cooling speed after a forged piece is cooled is found, part of the forged piece is unqualified, and a common middle section die is easy to damage and is generally made into a whole.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a assembling die for producing wheel hub forging to the mould before proposing in solving above-mentioned background art uses the back discovery forging cooling back because thickness is uneven, and cooling rate is different, causes horn mouth problem to appear in the bottom, and partial forging is unqualified, and general interlude mould damages easily, makes integratively usually, if each part damages, must all change, thereby causes the problem of maintaining required time and cost-push.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a assembling die for producing wheel hub forging, includes straight fundamental mode and core roller shell, the profile shapes is installed to one side of straight fundamental mode, and the inside of profile shapes is provided with the bottom roller shell, the core roller axle has been run through to the inside of core roller shell, and the core roller shell is located the top of bottom roller shell, the preceding table wall of core roller axle is provided with the spacing groove, and the inside of spacing groove is provided with spacing strip.

Preferably, the interior of the straight main mold is in a hollow cylindrical structure, and a central axis of the straight main mold is parallel to a central axis of the special-shaped piece.

Preferably, a part of the surface of one side of the inner wall of the special-shaped piece is tightly attached to the surface of the other side of the outer wall of the bottom roller sleeve, and the interior of the special-shaped piece is of a hollow cylindrical structure.

Preferably, the inner surface of the bottom roller sleeve is partially and tightly attached to the outer surface of the core roller shaft, and a trapezoidal structure is arranged above the cross section of the bottom roller sleeve.

Preferably, the inner wall size structure of the core roller sleeve is matched with the outer wall size structure of the core roller shaft, and the central axis of the core roller sleeve is coincided with the central axis of the core roller shaft.

Preferably, the core roller shaft and the core roller sleeve form a detachable structure through the matching between the limiting groove and the limiting strip, and the size structure of the inner wall of the limiting groove is matched with the size structure of the outer wall of the limiting strip.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses be provided with the profile shapes, the material is saved about 14% overall, the mould adopts 1 degree of tapering, because the mould used before found after the forging cools off because thickness is uneven, the cooling rate is different, cause to appear the horn mouth problem in the bottom, lead to part forging unqualified, after adopting 1 degree of tapering, the effectual problem of solving, adjusted the fillet and connected the inclined plane angle of fillet, do benefit to the mould and intervene the blank, accord with a material flow trend more, easily shaping, easily divide the material, avoid pressing from both sides the skin;

2. the utility model discloses a core roller adopts the combination formula, separately make core roller axle and core roller cover, save core roller manufacturing cost about 8%, save a large amount of core roller preparation time simultaneously, ordinary core roller preparation cycle is about 30 days, use behind the combination core roller, because the inner core roller of factory is standing by, consequently only need design preparation core roller cover when meetting the new product can, core roller cover preparation cycle is about 7 days, this makes the mill improve greatly to the response speed of new product, save mould change time in addition, general interlude mould damages easily, make integrative usually, if each part damages, must all change, and make that part that the components of a whole that can function independently only need to change the damage, save mould cost and live time.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a combined die for producing a hub forging comprises a straight main die 1 and a core roller sleeve 4, wherein a special-shaped piece 2 is installed on one side of the straight main die 1, a bottom roller sleeve 3 is arranged inside the special-shaped piece 2, the straight main die 1 is of a hollow cylindrical structure, the central axis of the straight main die 1 is parallel to the central axis of the special-shaped piece 2, one side surface of the inner wall of the special-shaped piece 2 is partially and tightly attached to the other side surface of the outer wall of the bottom roller sleeve 3, and the special-shaped piece 2 is of a hollow cylindrical structure;

core roller cover 4's inside is run through cored roller 5, and core roller cover 4 is located the top of bottom roller cover 3, the part closely laminates between the internal surface of bottom roller cover 3 and the surface of core roller 5, and the top of 3 cross sections of bottom roller cover sets up to trapezoidal structure, coincide each other between the outer wall dimensional structure of inner wall dimensional structure and the core roller 5 of core roller cover 4, and coincide each other between the axis of core roller cover 4 and the axis of core roller 5, the preceding table wall of core roller 5 is provided with spacing groove 6, and the inside of spacing groove 6 is provided with spacing 7, core roller 5 constitutes detachable construction through cooperation between spacing groove 6 and the spacing 7 with core roller cover 4, and coincide each other between the outer wall dimensional structure of inner wall dimensional structure and the spacing 7 of spacing groove 6.

The working principle is as follows: when using this assembling die for producing wheel hub forging, at first, separately make core roller 5 and core roller cover 4, ordinary core roller preparation cycle is about 30 days, after using the combination core roller, because factory's inner core roller 5 is standing by, consequently meet when new product only need design preparation core roller cover 4 can, core roller cover 4 preparation cycle is about 7 days, this makes the response speed of mill to new product improve greatly, and 1 tapering of accessible profile part 2, can effectually solve the mould and use the back discovery forging cooling because thickness is uneven, cooling rate is different, cause the problem that the horn mouth appears in the bottom.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
