Abstract
The utility model provides a clutch hub-type parts cold-working forming mold, comprising an upper mold and a lower mold, wherein the upper mold is a cylindrical raised mold, the perimeter of the upper mold is provided with external splines corresponding to the shape of internal splines of the clutch hub-type parts; the lower mold is a dish-shaped mold set and divided into three layers and opened with mold cavities and a lower mandrel is arranged in the mold cavity. The clutch hub-type parts are subject to cold-working one-time forming, the work load is lightened and the working efficiency is increased.
Description
Technical field
The utility model belongs to mould applications, relates in particular to a kind of clutch in the automatic transmission or brake hub class part carried out cold-formed mould.
Background technology
In automatic transmission, it is many that clutch or brake hub class part are used, and this type part adopts SPCC, and cold rolling or hot rolled steel plate such as SPHD has the structure of interior external tooth.
Such part is general to adopt cold-formed technology, because complex structure, conventional molds adds need process repeatedly man-hour; Not only workload is big, and working (machining) efficiency is low, does not meet the demand of batch process; Therefore, need produce special-purpose mould and adopt the cold working one-shot forming.
Summary of the invention
The goal of the invention of the utility model is can the one-time formed mould of clutch hub class part cold working be alleviated workload in order to solve deficiency of the prior art, to design, and increases work efficiency.
To achieve these goals; The technical scheme that the utility model adopted is: propose a kind of clutch hub class part and be cold worked into type die; Mould comprises patrix, and counterdie, patrix are cylindrical male; The patrix cylindrical has external splines, and external splines is corresponding with the internal spline shape of clutch hub class part; Counterdie is discoid set of molds, is divided into three layers, all has die cavity; Be provided with lower spindle in the die cavity; The die cavity wall of counterdie ground floor is a smooth surface, and the die cavity wall of the counterdie second layer is made up of a plurality of rollers, and roller quantity is identical with the external splines quantity of clutch hub class part; The shape that roller is formed is corresponding with the external splines shape of clutch hub class part, and the 3rd layer of counterdie is identical with counterdie second layer structure.
Further, counterdie can be divided into multilayer, and the number of plies is more than three, and from the mould layer of counterdie below the 3rd layer, structure is all identical with the counterdie second layer.
The procedure of processing of using the utility model to process is:
(1) will the fall blank of honest material is placed on directly over the die cavity on the counterdie.
(2) along with the moving down of patrix, blank receives the pressure of patrix, is deformed into cylinder downwards, and along with lower spindle moves down, blank forms cylindric through the extruding of counterdie ground floor.
(3) patrix continues to move down, and blank through the counterdie second layer, receives the extruding of roller along with lower spindle moves down together under the pressure of patrix, begins to take shape spline.
(4) patrix continues to move down, and blank through the 3rd layer of counterdie, receives the extruding of roller along with lower spindle moves down together once more under the pressure of patrix, and spline finally forms.
The beneficial effect of the utility model is: use the utility model, can clutch hub class part cold working one-shot forming be alleviated workload, increase work efficiency.

The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
As shown in Figure 1, the utility model comprises patrix 1, counterdie, and patrix 1 is columniform punch, and patrix 1 cylindrical has external splines 2, and external splines 2 is corresponding with the internal spline shape of clutch hub class part; Counterdie is discoid set of molds, is divided into three layers, all has die cavity 4; Be provided with lower spindle 8 in the die cavity; The die cavity wall of counterdie ground floor 5 is a smooth surface, and the die cavity wall of the counterdie second layer 6 is made up of a plurality of rollers 9, and roller 9 quantity are identical with the external splines quantity of clutch hub class part; The shape that roller 9 is formed is corresponding with the external splines shape of clutch hub class part, and the 3rd layer 7 of counterdie is identical with the counterdie second layer 6 structures.
Procedure of processing:
(1) will the fall blank 3 of honest material is placed on directly over the die cavity 4 of counterdie.
(2) as shown in Figure 2, along with moving down of patrix 1, blank 3 receives the pressure of patrix 1, is deformed into cylinder downwards, and along with lower spindle 8 moves down, blank 3 forms cylindric through the extruding of counterdie ground floor 5.
(3) as shown in Figure 3, patrix 1 continues to move down, and blank 3 through the counterdie second layer 6, receives the extruding of roller 9 along with lower spindle 8 moves down together under the pressure of patrix 1, begins to take shape spline.
(4) as shown in Figure 4, patrix 1 continues to move down, and blank 3 is along with lower spindle 8 moves down together under the pressure of patrix 1, and the 3rd layer 7 of process counterdie receives the extruding of roller 9 once more, and spline finally forms.
The above only is the preferred embodiment of the utility model; Be not that scope to the utility model limits; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the utility model protection domain.
