Abstract

The utility model provides a large-scale mould of centrifugal casting is from feeling relieved device, including last stretching strap, bolt and nut threaded connection are in last mould hole, and bolt upper end fixed connection goes up the stretching strap, goes up on stretching strap one end connection lifting hook, and the stretching strap under the bolt still fixedly connected with is drawn down to the bolt, and on the winding mechanism of establishing below the bed die was connected to the lower stretching strap other end, the stretching strap was closed fast to the mould lid on the shrink of winding mechanism down was made on the bed die. The upper die hung in the air can be contracted through the winding mechanism, so that the upper die is quickly close to the lower die, the alignment time of the upper die in the air is shortened, the die assembling efficiency is improved, and the production efficiency is improved.

Description

Self-centering device of large centrifugal casting mold

Technical Field

The utility model relates to a centrifugation equipment production field of pouring, concretely relates to self-centering device of large-scale mould of centrifugal casting.

Background

Centrifugal casting equipment is because bulky, at production centrifugal casting equipment spare part in-process, its mould needs assemble, because the mould size is great, need use the crane to hoist the equipment with relevant mould in the assembling process, but because the crane is difficult control in the air, mould alignment time about often needing longer time adjustment leads to work efficiency to reduce.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a large centrifugal casting mould self-centering device with high working efficiency.

The utility model discloses a following technical scheme realizes: the utility model provides a large-scale mould of centrifugal casting is from feeling relieved device, includes stretching strap, bolt and nut, the bolt with nut threaded connection is in last mould hole, bolt upper end fixed connection go up the stretching strap, go up on stretching strap one end connection lifting hook, stretching strap under the bolt still fixedly connected with, the stretching strap other end is connected and is established on the winding mechanism of bed die below down, winding mechanism shrink the stretching strap makes down it closes to go up the quick lid of mould on the bed die.

Preferably, the winding mechanism comprises a supporting table, rollers are arranged in the supporting table, the rollers are fixedly connected to a rotating shaft, a bearing of the rotating shaft is connected to the supporting table, and one end of the rotating shaft penetrates through the supporting table to be connected with the motor.

Preferably, the lower pull belt comprises a plurality of upper sections and a plurality of lower sections, one end of each upper section is uniformly arranged on the upper die, the other ends of the plurality of upper sections are all fixedly connected with one end of each lower section, and the other ends of the lower sections are wound on the rollers.

Compared with the prior art, the utility model provides a self-centering device of large-scale mould of centrifugal casting, including last stretching strap, bolt and nut threaded connection are in last mould hole, and on the stretching strap was connected to bolt upper end fixed connection, on the lifting hook was connected to last stretching strap one end, the stretching strap under the bolt still fixedly connected with was drawn to the bolt, and on the winding mechanism of drawing the other end connection establishment in the bed die below was drawn to the lower side, the winding mechanism shrink down the stretching strap make the mould fast lid close on the bed die is last. The upper die hung in the air can be contracted through the winding mechanism, so that the upper die is quickly close to the lower die, the alignment time of the upper die in the air is shortened, the die assembling efficiency is improved, and the production efficiency is improved.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is an enlarged view taken at A in FIG. 1;

in the figure: 1. an upper die; 2. a lower die; 3. pulling the belt upwards; 4. a bolt; 5. a nut; 11. an upper die hole; 6. a lower drawstring; 61. an upper section; 62. a lower section; 7. a winding mechanism; 71. a support table; 73. a roller; 72. a rotating shaft; 74. an electric motor.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2: the utility model provides a large-scale mould of centrifugal casting is from feeling relieved device, includes upper stretching strap 3, bolt 4 and nut 5, bolt 4 with nut 5 threaded connection is in

last mould hole

11, 4 upper end fixed connection of bolt on the upper stretching strap 3, on the 3 one end connection lifting hook of upper stretching strap, the crane passes through the lifting hook pulling upper stretching strap 3 will 1 of upper mould lifts by crane, stretching strap 6 under bolt 4 still fixedly connected with, 6 other end connections of lower stretching strap are established on 2 below of bed die winding mechanism 7, winding mechanism 7 shrink down stretching strap 6 makes 1 quick lid of upper mould closes on the bed die 2. When the device is used, the winding mechanism 7 can shrink the upper die 1 hung in the air, so that the upper die 1 is quickly close to the lower die 2, the alignment time of the upper die 1 in the air is shortened, the die assembly efficiency is improved, and the production efficiency is improved.

Winding mechanism 7 includes brace table 71, fixed bed die 2 directly over brace table 71, be equipped with gyro wheel 73 in the brace table 71, the winding goes up on the gyro wheel 73 draw belt 6 down, gyro wheel 73 fixed connection is on pivot 72, pivot 72 bearing is connected on brace table 71, pivot 72 one end is passed brace table 71 links to each other with motor 74. The motor 74 drives the rotating shaft 72 to rotate, so as to drive the roller 73 fixed on the rotating shaft 72 to rotate, the roller 73 rotates to wind the upper pull belt 3 on the roller 73, and then the upper die 1 is pulled to be fast close to the lower die 2, so that the alignment time of the upper die 1 in the air is shortened.

The lower pull belt 6 comprises an upper section 61 and a lower section 62, the upper section 61 is multiple, one end of the upper section 61 is uniformly arranged on the upper die 1, the other end of the upper section 61 is fixedly connected with one end of the lower section 62, and the other end of the lower section 62 is wound on the roller 73. Evenly connect in the upper segment 61 of last mould 1 when mould 1 is gone up in the pulling, can guarantee to go up mould 1 steady movement, can not take place the slope, mould 2 aligns about the convenience.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
