There are mainly 5 working steps using a blade root skin cutting device:
(1) carrying and assembling equipment:
a. two operators carry the guide unit to the blade root tile die, place the guide unit into the positioning pin and install the guide unit by using a butterfly bolt;
b. two operators carry the base unit to the guide unit and install the base unit by using butterfly bolts;
c. two operators transfer the machining unit to the sliding table unit and install the machining unit by using the butterfly bolt.
(2) A connecting system: an operator screws the dust removal pipe to the connection mechanism using the hose clamp, and places the submersible pump in the water tank.
(3) Electrifying: an operator turns on the main switches of the dust removal equipment, the submersible pump and the processing unit.
(4) Cutting: and (5) horizontally pushing equipment by an operator to finish skin cutting. During the cutting process, an operator can put the string on the string according to the requirement
And moving the processing unit to ensure the cutting effect.
(5) Tool homing: after the machining is finished, two operators gradually disassemble the machining unit, the sliding table unit and the guide unit.
In the process of assembling and disassembling the blade root skin cutting equipment, two operators are required to participate, and the total time of the actual assembling and disassembling process is within 10 minutes.
Compared with the prior art, the cutting process for the blade root skin has the following five differences:
(1) personnel: in the existing skin cutting process, two operators are adopted, one operator is responsible for cutting the skin, and the other operator is responsible for spray cooling
Water cooling, dust removal and other auxiliary work. The operator in charge of the auxiliary work cannot perform the cooling water spraying and dust removing work at the same time. The sprayed cooling water can cool the grinding wheel and also can play a role in dust removal;
in the project scheme, two operators complete the dismounting work of the skin cutting equipment, and only one operator is responsible for cutting. Another operator may simultaneously cut the other side of the die. The dust removal device and the cooling water system are integrated on the processing unit. Although no separate operator is responsible for dust removal and water cooling, both tasks can be performed automatically by the apparatus at the same time.
(2) A machine: the equipment needed to be used in the existing skin cutting process comprises: angle grinder, dust collecting equipment, watering can and main forming die.
The equipment that needs to be used in this project scheme is: blade root skin cutting equipment, dust catcher, blade root tile mould. The submersible pump nozzle and the dust collector equipment pipeline are integrated on the blade root skin cutting equipment processing unit.
(3) Materials: the existing skin cutting is carried out on a semi-finished blade before a main forming die is bonded, and the time of a main forming procedure is occupied.
The cutting of the blade root skin in the device is carried out on the blade root tile prefabricated part of the blade root tile mould. The time of the main forming procedure is not occupied.
(4) The method comprises the following steps: the existing skin cutting process comprises the following steps: firstly, building a dustproof shed → secondly wearing protective clothing → thirdly, repeatedly cutting a blade root skin by an operator so as to ensure the surplus height without damaging a die; one operator does auxiliary work such as dust removal and cooling → two operators arrange the angle grinder and the dust removal system back to the original position.
The skin cutting process of the device comprises the following steps: firstly, two operators wear protective clothing → secondly, the two operators carry, assemble and cut the equipment → thirdly, one operator uses the equipment to cut the blade root tile skin → fourthly, the two operators arrange the equipment and the dust removal system to return to the original position.
(5) Environment: the existing skin cutting process needs to be provided with a dustproof shed to ensure that the dust removal efficiency meets the environmental protection requirement. This equipment has improved dust collection efficiency greatly through automatic water feeding system. Because the improvement of dust collection efficiency, this device need not set up dustproof canopy on probation. The dust removing equipment configuration can also be reduced.
In the original process, as the blade root skin is cut on the main forming die, in order to avoid the reaction of moisture and ammonia in the adhesive glue, the moisture is not allowed to be used for dust reduction. In the device, the blade root skin is sprayed with water and cut on the blade root tile die, after cutting, the die is removed, and after about 2 hours, the blade root skin can be poured, and the 2 hours are enough to ensure the complete evaporation of water.
The above is only a preferred embodiment of the invention, and any simple modifications, variations and equivalents of the invention may be made by anyone in light of the above teachings and fall within the scope of the invention.
