Abstract
Disclosed is a spring-shaped heated treating mold of a clutch diaphragm for producing diaphragm springs, comprising an upper mold, a lower mold and a locating core, wherein the upper mold and the lower mold are in engagement, and the locating core is arranged between the upper mold and the lower mold. A cooling cavity, a cooling fluid inlet and a cooling fluid outlet are installed in the upper mold and in the lower mold, and the cooling fluid inlet and the cooling fluid outlet are corresponded to each other. The yield of the diaphragm springs made by the utility model is high, and the shape of the diaphragm springs can be controlled at will, thereby meeting the need of the loading section between a peak value and a valley.
Description
Technical field: the utility model relates to a kind of thermal treatment mould, particularly the thermomechanical treatment mould of clutch diaphragm spring.
Background technology: the technical requirements for the diaphragm spring in the clutch coupling is quite strict, and its deformation quantity and number of times standard are all very high.General diaphragm spring thermomechanical treatment mould is with workpiece clamp die mould between upper and lower mould, is provided with the straight-through workpiece in quenching oil duct when keeping shape in upper and lower mould, quenching oil is pressed into to contact with workpiece quenches.Adopt this formed in mould diaphragm spring shape to be difficult to control, deflection is big, requires between the peak value of diaphragm spring and valley loading zone to be difficult to satisfy and to adjust to adapt to, and yield rate is low.
Summary of the invention: at the deficiency of existing mold, the utility model provides a kind of yield rate height, the controllable clutch diaphragm spring thermomechanical treatment of forming shape mould.
The utility model comprises the upper die and lower die that match, and places location core between the two, is equipped with cooling chamber and corresponding cooling fluid and imports and exports in upper die and lower die.
Workpiece is placed on upper and lower mould to compressing moulding, in cooling chamber, feeds cooling fluid simultaneously, utilize the thermal conduction of mould and workpiece that workpiece is quenched, the diaphragm spring deformation quantity that makes is very little, shape can be controlled arbitrarily, can adapt to requirement between peak value and valley loading zone, the yield rate height.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the main synoptic diagram of embodiment.
Embodiment: as shown in the figure, location core 3 places between patrix 1 and the counterdie 2, is equipped with cooling chamber 4 and corresponding cooling fluid and imports and exports 5 in patrix 1 and counterdie 2.Safeguard for convenience and processing cooling chamber 4, can all be sealedly connected with die cap 6 above the patrix 1 or below the counterdie 2, the cut-out driving fit of the cut-out of die cap 6 and corresponding patrix 1 or counterdie 2 constitutes cooling chamber 4.
Patrix 1 and counterdie 2 are generally used low alloy steel, and both die faces can be processed into multiple shape, and diaphragm spring also is shaped to corresponding shape, owing to adopt thermal conduction to quench, can adjust between the peak value of diaphragm spring and valley loading zone and satisfy the demands the yield rate height.
Claims (2)
