Description

Die for controlling length of head of oil core
Technical Field
The invention belongs to the field of assembly of an aviation turbine cooler oil core, and particularly relates to a die for controlling the length of the head of the oil core.
Background
The oil core is an important part for ensuring cooling and lubrication of the ball bearing turbine cooler, and directly influences the service life of the ball bearing. The length control of the oil core head is related to the effective cooling and lubrication of the ball bearing. The oil core used by the turbine cooler is usually made of wool felt materials and is processed and formed by adopting an extrusion method, the size of the head of the oil core often exceeds a required value, and the accurate control of the length of the head of the oil core is an important means for ensuring the reliability of the ball bearing turbine cooler.
Disclosure of Invention
The invention aims to provide a die for controlling the length of an oil core head, which can realize accurate control of the length of the oil core head.
Technical scheme
A mould for controlling the length of the head of an oil core,
comprises a bottom die 1, a pin 2 and a top die 3;
the bottom die 1 and the top die 3 are fixedly connected through a pin 2.
The bottom die 1 and the top die 3 are respectively provided with 6 groups of semicircular grooves.
The diameter of the semicircular groove is phi 7.
The depth of the semicircular groove is 3.5 mm.
Has the advantages that: the die for controlling the length of the oil core head can realize the accurate control of the length of the oil core head and improve the cooling and lubricating effects of the ball bearing of the turbine cooler.
Drawings
FIG. 1 is a block diagram of an oil core and an oil core head;
wherein 4 is the head part of the oil core, and 5 is the base body of the oil core.
FIG. 2 is a diagram of a die structure for controlling the length of a wick head;
FIG. 3 is a schematic diagram of the operation of the die for controlling the length of the wick according to the present invention;
1-bottom die, 2-pin, 3-top die, 4-oil core head and 5-oil core base body.
Detailed Description
The invention is described in further detail below with reference to the accompanying drawings, which refer to fig. 1-3 of the specification.
FIG. 1 is a structural diagram of an oil core and an oil core head, wherein the oil core head is in a cylindrical convex shape, the length of the head of the oil core is 3.5, the oil core plays a vital role in cooling and lubricating a ball bearing, the oil core is made of wool felt, and the part of the cylindrical convex part of the oil core is processed by extrusion forming.
Referring to fig. 2, the invention relates to a die for controlling the length of an oil core head, which comprises a bottom die 1, a pin 2 and a top die 3.
Wherein, the bottom die 1 and the top die 3 are fixedly connected through the pin 2. The bottom die 1 and the top die 3 are respectively provided with 6 groups of semicircular grooves with the diameter of phi 7 and the depth of 3.5 mm.
FIG. 3 is a schematic diagram of the operation of a die for controlling the length of a wick head according to the present invention. When the oil core 5 falls into the semicircular groove of the bottom die 1 and is fixedly connected through the pin 2, the bottom die 1 is combined with the top die 3, the oil core 5 is pulled to enable the head part 4 of the oil core to be embedded into a phi 7 hole groove of the die, and the length of the head part 4 of the oil core extending out of or lower than the end faces of the bottom die 1 and the top die 3 is observed. The extending part of the oil core head part 4 is trimmed by a blade, the oil core head part 4 is lower than the end surfaces of the bottom die 1 and the top die 3, and the oil core 5 is replaced, so that the length of the oil core head part is accurately measured.
