Abstract
The utility model discloses a cam ring cold finishing die with ratchets. The cam ring cold finishing die comprises an upper die plate, guide sleeves, guide columns, an upper die, a lower die and a bottom die base. A die frame is jointly composed by the upper die plate, the guide sleeves, the guide columns and the bottom die base. The lower die is arranged in the middle of the upper end face of the bottom die base, an opening of a concave die cavity of the lower die faces upwards, wherein the concave die cavity is used for containing a blank, and the concave die cavity for containing three cams of the blank (7) is formed in the cavity bottom. The upper die is arranged on the bottom face of the upper die plate, the upper die faces to the lower die in a coaxial mode, the die head of the upper die is in a thick wall round tube shape, the outer circle of the die head is in interference fit with the concave die cavity of the lower die, and the ratchets are evenly distributed on the end face facing downwards. During cold finishing operation, one face, with the cams, of the blank at normal temperature is horizontally arranged downwards in the concave die cavity of the lower die, the upper die plate and the upper die at the upper position are driven by a pressure head of a pressure machine to press downwards along the guide columns, and the blank in the cold finishing die is extruded out of the ratchets. The ratchets on the cam ring are extruded and formed through the cold finishing die, production efficiency is high, precision is good, and quality is stable.
Description
Technical field
The utility model relates to a kind of forging die structure, and specifically, the utility model relates to a kind of cam ring cold-finish mould with ratchet.
Background technology
Cam ring in automotive transmission belongs to precision component, and its architectural feature is uniform three cams of one side, and another side is provided with three cam coaxials and has the ratchet of higher position precision.For cam ring processing, first industry conventional fabrication processes is made three cams by forge hot and is shaped, and then take three cams as the origin reference location ratchet of milling another side indent sequentially again.Although this kind of substep processing technology is simple, ripe, can reach prospective quality.But, too low by tab order milling ratchet efficiency, and intensity does not reach requirement.Production cost is large, does not conform to batch production beat.
Utility model content
The utility model, mainly for the inefficient problem of prior art substep milling ratchet, proposes a kind of cam ring cold-finish mould with ratchet, and this mould structure is simple, making is easy, compacting efficiency is high, forming quality stable.
The utility model is achieved through the following technical solutions technical goal.
With the cam ring cold-finish mould of ratchet, it comprises cope match-plate pattern, fairlead, guide pillar, upper die and lower die, bed die seat.Described cope match-plate pattern, fairlead and guide pillar, the common mould bases that forms upper and lower relative sliding of bed die seat.Described bed die seat upper surface location and installation counterdie placed in the middle, the matrix cavity that counterdie is taken blank in is upward uncovered, is provided with the cavity of taking three cams of blank at the bottom of chamber.Cope match-plate pattern bottom surface location and installation patrix, patrix is coaxially relative with counterdie.Its improvements are: the die head of described patrix is thick-walled tube shape, the matrix cavity matched in clearance of its cylindrical and counterdie, the uniform ratchet towards lower surface.
The utility model compared with prior art, has following good effect:
The cold-finish mode structure of 1, keeping straight on is up and down simple, is shaped easily, and production efficiency is high;
2, ratchet is by cold-finish mould extrusion molding, and precision is high, steady quality;
3, adopt the ratchet of cold-finish mould extruding still to retain the original metal fibrous tissue of blank, blank facilitates metal structure finer and close after extruding, is conducive to further improve the intensity of ratchet and whole cam ring.
Accompanying drawing explanation
Fig. 1 is the utility model agent structure generalized section.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Shown in Fig. 1, with the cam ring cold-finish mould of ratchet, it comprises cope match-plate pattern 1, fairlead 2, guide pillar 3, patrix 4, counterdie 5, bed die seat 6.Described cope match-plate pattern 1, fairlead 2 and guide pillar 3, the common mould bases that forms upper and lower relative sliding of bed die seat 6, in the present embodiment, bed die seat 6 horizontal are on press bench, and cope match-plate pattern 1 moves up and down with the pressure head of forcing press.Described bed die seat 6 upper surface location and installation counterdies 5 placed in the middle, the matrix cavity that counterdie 5 is taken blank 7 in is upward uncovered, is provided with the cavity of taking 7 three cams of blank at the bottom of chamber.Cope match-plate pattern 1 bottom surface location and installation patrix 4, patrix 4 is coaxial relative with counterdie 5.In the present embodiment, the die head of patrix 4 is thick-walled tube shape, the matrix cavity matched in clearance of its cylindrical and counterdie 5, the uniform ratchet towards lower surface.
In the present embodiment, the blank 7 of cold-finish processing to be done is the semi-finished product through hot forging forming, and the one side that is wherein provided with cam is just swaged into shape, and another side is plane, treats that further cold-extruded extrudes ratchet.During cold-finish operation, first have one of cam to face down the blank of normal temperature 7 and keep flat in the matrix cavity of counterdie 5, be in upper cope match-plate pattern 1 and patrix 4 is driven by press ram, along guide pillar 3, exert pressure downwards, blank 7 is extruded ratchet by cold-extruded in cold-finish mould.Ratchet on cam ring is by cold-finish mould extrusion molding, and production efficiency is high, and precision is good, steady quality.Benefit is on the other hand through the ratchet of cold-finish mould extruding, still retains the original metal fibrous tissue of blank 7 and metal structure finer and close, is conducive to further improve the intensity of ratchet and whole cam ring.
