Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of aviation manufacturing, and particularly relates to a wide high-finned wall plate efficient unfolding and straightening integrated device and a method thereof. BACKGROUND

[0002] Aiming at the key bearing components of aviation carrying equipment, such as high-finned wall plates, the manufacturing level has a very important influence on the performance, manufacturing cost and manufacturing cycle of aviation equipment.

[0003] The fuselage wall plate is a key bearing structure of a large aircraft, bears the fuselage bending, shearing and torsional load and the like working conditions, accounts for 35% to 45% of the fuselage structure, and through reasonable structural optimization design, adoption of light materials and advanced manufacturing technology, the weight of the aircraft structure can be greatly reduced, and the comprehensive performance of the aircraft is improved. Since the fuselage wall plate of a large aircraft has very high requirements on bearing performance, a light high-strength aluminum alloy is usually used for manufacturing.

[0004] There are mainly three manufacturing processes for the fuselage wall plate of the existing large aircraft. The first one is to adopt a skin stringer assembly structure, respectively form a skin and a stringer, and then connect the skin and the stringer by riveting. This kind of assembly structure leads to large weight of the wall plate, long manufacturing cycle and difficult to guarantee the riveting quality. The second one is to connect the skin and the stringer by laser welding. Although this kind of connection method can realize weight reduction of the structure, it is easy to cause stress concentration and complex deformation and the like problems, and the welding quality at the interface between the skin and the stringer is difficult to guarantee. The third one is to adopt an extrusion process to extrude a high-finned cylindrical piece, and then to unfold the high-finned cylindrical piece into a high-finned flat piece. This process route can greatly increase the width of the manufactured high-finned wall plate, and is an ideal forming process for manufacturing an integral wide high-finned wall plate.

[0005] Patent document CN109277422A discloses a wide high-fillet thin-walled plate prepared by preheating, extrusion forming, finishing treatment, and unfolding processes, but does not specifically disclose the unfolding details of the cylindrical part. Patent document CN109277422A discloses an unfolding and straightening method for an arc segment of a thin-walled cylindrical part with outer transverse fillets. This patent is only suitable for unfolding and straightening the arc segment of the arc segment thin-walled cylindrical part, but is not suitable for unfolding and straightening the cylindrical part with a "whole circular" cross section. Patent document CN114042779B discloses a method for unfolding an integral extrusion-formed aluminum alloy cylindrical part with fillets into a flat plate part with fillets through processes such as splitting, unfolding, roll initial straightening, stretch straightening, roll intermediate straightening, and roll precision straightening. Compared with the above, this process is relatively complicated, and the efficiency of preparing a wide high-fillet wall plate is not high for aluminum alloys with a large springback amount and a high yield strength. Patent document CN113909329B discloses a wall plate blank formed by an extrusion process through an unfolding die. Compared with the above, the efficiency of the wall plate blank prepared by this process needs to be further improved. With the fierce competition in the field of aerospace among countries in the future, there is a huge demand for wide high-fillet wall plates similar to load-bearing members, and the efficiency of their preparation is an extremely important indicator.

[0118] The application further provides a wide-width high-fillet wallboard high-efficiency unfolding and straightening method, which adopts the wide-width high-fillet wallboard high-efficiency unfolding and straightening integrated device as described above, and specifically comprises the following steps:

[0119] Step 1, drilling and cutting of the ribbed cylindrical part 01;

[0120] Step 2, fixing the ribbed cylindrical part 01 on the cylindrical part fixing lifting table 2;

[0121] Step 3, preliminary stretching of the ribbed cylindrical part 01, stretching from the middle of the left and right side skins of the ribbed cylindrical part to separate the cutting part;

[0122] Step 4, connecting the separated cutting edge of the ribbed cylindrical part with the chain stretching table 3;

[0123] Step 5, secondary stretching of the ribbed cylindrical part, and unfolding to obtain a locally uneven high-fillet wallboard 02;

[0124] Step 6, placing the locally uneven high-fillet wallboard on the roller conveyor 93 and adjusting the position of the high-fillet wallboard 02;

[0125] Step 7, starting the main motor 92 to drive the front end pinch assembly 6 and the straightening roller assembly 7 to rotate through the gear box 8 and the universal coupling assembly 91;

[0126] Step 8, adjusting the front end pinch assembly 6 and the straightening roller assembly 7 according to the situation of the high-fillet wallboard;

[0127] Step 9, feeding the high-fillet wallboard 02 into the front end pinch assembly 6 and the straightening roller assembly 7 from the entrance of the front end pinch assembly 6 to complete the first forward straightening;

[0128] Step 10, starting the main motor 92 to rotate reversely, feeding the high-fillet wallboard 02 into the straightening roller assembly 7 and the front end pinch assembly 6 from the outlet of the straightening roller assembly 7 to complete the first reverse straightening;

[0129] Step 11, after adjusting the front pinch assembly 6 and the straightening roller assembly 7 again, the second forward straightening and the second reverse straightening are completed, and the above adjustment operation and straightening operation are repeated until the high rib wall plate 02 after straightening meets the straightening requirements.

[0130] In step 1, the line is drawn on the cut and drilled area of the ribbed cylindrical part 01. The material of the ribbed cylindrical part is high-strength aluminum alloy. The drilled area is drilled to form an expanded hole. The diameter of the expanded hole is 6mm. The arrangement of the expanded hole is arranged according to the through hole of the expanded bolt set installed on the second expanding clamp. The cut line is cut.

[0131] In step 2, first, the ribbed cylindrical part after cutting and drilling is placed on the I-beam base with the cut seam facing up. The two cylindrical part end blocks are respectively abutted against the two end faces of the ribbed cylindrical part. The two small sliders are respectively slid into the grooves of the I-beam base. The inner hexagonal bolts are passed through the through holes of the bottom grooves of the cylindrical part end blocks, and are screwed into the threaded holes of the small sliders. The inner hexagonal bolts and the small sliders are screwed to fix the cylindrical part end blocks, thereby limiting the movement of the ribbed cylindrical part in the forward and backward directions.

[0132] Secondly, the cylindrical part pressing block is added on the inside bottom skin of the ribbed cylindrical part. The cylindrical part pressing block, the cylindrical part end block and the I-beam base are connected together through the cylindrical part fixing bolts to prevent the rotation of the ribbed cylindrical part during the unfolding process.

[0133] In addition, the I-beam base and the screw I-beam base connecting sleeve are connected together by bolt connection. The side with threaded holes of the screw I-beam base connecting sleeve is threadedly connected with the upper end of the screw in the elevator. The screw elevators are commercially purchased. By rotating the hand crank, the input shaft of the screw elevator is rotated through the coupling, thereby driving the screw of the screw elevator to move up and down, and the I-beam base of the cylindrical part fixing lifting platform is moved up and down.

[0134] In step 3, first, the hand crank is rotated to raise the I-beam base of the cylindrical part fixing lifting platform to an appropriate height. The first expanding clamp is used to clamp the middle part of the left and right side skins of the ribbed cylindrical part, and the expanding chain is in a relatively horizontal position. The first expanding clamp and the expanding chain are connected through the connecting ear hole, the clasp ring and the slotted pin. During the expanding process of the expanding chain, the rotation of the servo motor at both ends of the steel frame drives the servo screw to rotate. The ball screw shaft sleeve of the chain expanding table is connected with the servo screw through threads, so that the two chain expanding tables move to the left and right ends along the second guide rail on the steel frame. The distance of the chain expanding table sliding along the guide rail is accurately controlled by the servo motor.

[0135] The speed reducer motor on the left / right chain stretching station is turned on, the speed reducer motor rotates to drive the rubber synchronous belt and the synchronous belt pulley to rotate, and further transmits the torque to the transmission shaft to drive the chain wheel to rotate, the chain and the chain wheel are engaged to realize the stretching of the chain on the ribbed cylindrical part, the stretching process is as slow as possible, the rotating speed is adjusted to be less than or equal to 5 revolutions per minute, and after multiple reciprocating stretching, the ribbed cylindrical part is stretched until the distance between the cut edges of the ribbed cylindrical part is greater than the radius of the ribbed cylindrical part after the stretching chain is removed.

[0136] In step 4, the ribbed cylindrical part after the initial stretching is clamped at the cut edge by the second stretching clamp. The second stretching clamp includes a stretching upper clamp, a stretching lower clamp, and a stretching bolt set. The stretching upper clamp and the stretching lower clamp each have six 6mm diameter countersunk holes. The stretching bolt set is tightened after passing through the countersunk holes of the stretching upper clamp, the stretching holes of the cut edge of the ribbed cylindrical part, and the countersunk holes of the stretching lower clamp, so that the second stretching clamp clamps the cut edge of the ribbed cylindrical part.

[0137] One stretching chain on the chain stretching station is connected to one chain connecting hole on the second stretching clamp through a slotted pin and a snap ring, and the other stretching chain on the chain stretching station is also connected to the other chain connecting hole on the second stretching clamp through a slotted pin and a snap ring.

[0138] In step 5, in order to stretch the circular arc segment at the cut edge into a relatively flat state, the sliding lifting support tables on both sides need to move horizontally along the left and right directions of the first guide rail during the stretching process. The servo motor is turned on to make the chain stretching stations on both sides move slowly along the second guide rail to the left and right ends of the steel frame. The speed reducer motors on the chain stretching stations on both sides are turned on to realize the secondary stretching of the ribbed cylindrical part by the chain stretching stations.

[0139] During the secondary stretching process, the horizontal movement distance of the sliding lifting support tables on both sides needs to be adjusted constantly. The speed reducer motor drives the second lead screw lifters through the couplings to simultaneously lift the lead screws in the two second lead screw lifters. During the chain stretching process, the two flanges fitted on the sliding support round bars are respectively abutted against the two end faces of the ribbed cylindrical part.

[0140] At this time, the first lead screw lifter needs to be adjusted by hand to adjust the lifting height of the lead screw, so that the stretching chain is at a suitable stretching angle. The movement distance of the chain stretching station, the fulcrum height of the sliding support round bar of the sliding lifting support table, and the lifting height of the cylindrical part fixing lifting table are adjusted multiple times during the chain stretching process until the ribbed cylindrical part is stretched to the over-bending state.

[0141] Finally, slowly move the chain stretching and reducing station and lower the lifting height of the cylindrical part fixing lifting station, so that the stretching and reducing chain is in a non-tight state, the stretching and reducing chain is unloaded, the ribbed cylindrical part rebounds, and the required local uneven high-rib wall plate 02 is formed.

[0142] In step 6, the local uneven high-rib wall plate is placed on the drum conveyor 93, and when the position of the high-rib wall plate is adjusted, the four ribs of the high-rib wall plate correspond to the four grooves on the upper front end lower pressing pinch roller respectively.

[0143] At this time, the side limiting assemblies on both sides of the inlet of the front end pinch assembly respectively abut against the two end faces of the high-rib wall plate. The subsequent feeding of the high-rib wall plate into the front end pinch assembly is prevented from moving in the two side directions, so that the rib position deviates, the rib cannot be smoothly transmitted along the grooves of the upper lower pressing No. 1 roller and the upper lower pressing No. 2 roller, and the rib of the high-rib wall plate is at risk of being damaged.

[0144] In step 7, the main motor is started to rotate in the forward direction through the operation panel, the forward rotation of the main motor transmits the torque to the lower pinch transmission shaft with a key groove through the large coupling, the lower pinch transmission shaft drives the lower pinch universal coupling through the flange shaft sleeve, and the lower pinch universal coupling further transmits the torque to the lower front end pinch roller through the flange shaft sleeve connection and rotates the lower front end pinch roller.

[0145] At the same time, the rotation of the lower pinch transmission shaft with a key groove drives the lower bevel gear and the lower spur gear to rotate through the key connection, the rotation of the lower bevel gear drives the upper bevel gear to rotate through gear meshing, and further the rotation of the upper bevel gear drives the upper pinch transmission shaft with a key groove and the upper spur gear to rotate through the key connection.

[0146] At the same time, the rotation of the upper pinch transmission shaft with a key groove transmits the torque to the flange shaft sleeve, drives the upper pinch universal coupling connected with the flange shaft sleeve to rotate, and further transmits the torque to the flange shaft sleeve through the upper pinch universal coupling, and drives the upper front end lower pressing pinch roller to rotate.

[0147] At the same time, the rotation of the upper spur gear drives the 1# transmission spur gear to rotate through gear meshing, the rotation of the 1# transmission spur gear drives the straightening upper 1# gear to rotate through gear meshing, the rotation of the straightening upper 1# gear drives the 2# transmission spur gear to rotate through gear meshing, and the rotation of the 2# transmission spur gear drives the straightening upper 2# gear to rotate through gear meshing.

[0148] Similarly, the lower spur gear rotates through gear engagement to make the 3# transmission spur gear rotate, the 3# transmission spur gear rotates through gear engagement to make the straightening lower 3# gear rotate, the straightening lower 3# gear rotates through gear engagement to make the 4# transmission spur gear rotate, the 4# transmission spur gear rotates through gear engagement to make the straightening lower 4# gear rotate, the straightening lower 4# gear rotates through gear engagement to make the 5# transmission spur gear rotate, and the 5# transmission spur gear rotates through gear engagement to make the straightening lower 5# gear rotate. In turn, the entire gear box is engaged and rotated.

[0149] Among them, the 1# transmission spur gear, the 2# transmission spur gear, the 3# transmission spur gear, the 4# transmission spur gear and the 5# transmission spur gear only play a transmission role through gear engagement. However, the straightening upper 1# gear, the straightening upper 2# gear, the straightening lower 3# gear, the straightening lower 4# gear and the straightening lower 5# gear each need to transmit torque to the corresponding flange shaft sleeve, the corresponding universal coupling and the corresponding roller through the corresponding key groove transmission shaft, so as to realize the rotation of the upper 1# roller, the upper 2# roller, the lower 3# rotating roller, the lower 4# rotating roller and the lower 5# rotating roller.

[0150] Among them, the rotation direction of the upper 1# roller and the upper 2# roller is opposite to the rotation direction of the lower 3# rotating roller, the lower 4# rotating roller and the lower 5# rotating roller.

[0151] In step 8, first, the maximum height H of the uneven area of the high-stiffness wall plate skin is measured, and then the amount of the first time is set. The roller gap between the upper front end pinch roller and the lower front end pinch roller is set to H-1mm. At the same time, the roller gap between the upper 1# roller, the upper 2# roller and the lower 3# rotating roller, the lower 4# rotating roller and the lower 5# rotating roller is also H-1mm. The upper 1# roller, the upper 2# roller and the upper front end pinch roller have a downward movement. Each roller with a downward movement is matched with a downward mechanism. Taking the upper 1# roller as an example, its corresponding downward mechanism is the 1# roller downward mechanism.

[0152] The third worm gear reducer rotates to transmit torque to the input shaft of a third screw rod elevator to make it rotate, and then the screw rod of the third screw rod elevator moves downward, so that the first lower block connected to the lower end of the screw rod realizes the downward movement. At the same time, the connecting rod transmits torque to the other third screw rod elevator through the coupling to realize the synchronous downward movement of the two first lower blocks. The two ends of the upper 1# roller are placed in the roller mounting holes of the two first lower blocks, and the synchronous downward movement of the two first lower blocks realizes the downward movement of the upper 1# roller on the high-stiffness wall plate.

[0153] In step 9, the high-stiffness wall plate is clamped into the upper front end pinch roll and the lower front end pinch roll, and sequentially passes through the lower 3# rotating roll, the upper 1# pinch roll, the lower 4# rotating roll, the upper 2# pinch roll, the lower 4# rotating roll, until the high-stiffness wall plate is conveyed to the roller conveyor at the rear end, i.e. the first forward straightening is completed.

[0154] In step 10, the main motor is reversed, the position of the high-stiffness wall plate is adjusted on the roller conveyor at the rear end, and the four ribs of the high-stiffness wall plate correspond to the four grooves of the upper 2# pinch roll. At this time, the side limit assemblies at the outlet of the straightening roll assembly abut against the two end faces of the high-stiffness wall plate. The high-stiffness wall plate sequentially passes through the lower 5# rotating roll, the upper 2# pinch roll, the lower 4# rotating roll, the upper 1# pinch roll, the lower 3# rotating roll, the upper front end pinch roll and the lower front end pinch roll, until it is conveyed to the roller conveyor at the front end, and the first reverse straightening is completed.

[0155] In step 11, the amount of the second pinch is set so that the roll gap of the upper 1# pinch roll, the upper 2# pinch roll, the lower 3# rotating roll, the lower 4# rotating roll and the lower 5# rotating roll is H-1.5mm. After the second forward / reverse straightening of the high-stiffness wall plate, the amount of the third pinch is set so that the roll gap of the upper 1# pinch roll, the upper 2# pinch roll, the lower 3# rotating roll, the lower 4# rotating roll and the lower 5# rotating roll is H-2mm, and the third forward / reverse straightening is completed. After the amount of the pinch is set for several times, the amount of the pinch is set in the last step so that the roll gap of the upper 1# pinch roll, the upper 2# pinch roll, the lower 3# rotating roll, the lower 4# rotating roll and the lower 5# rotating roll is the skin thickness 2.4mm. Since the high-stiffness wall plate has a certain rebound phenomenon after each pinch, the high-stiffness wall plate needs to be repeatedly straightened in the forward / reverse direction until the local uneven area is straightened to a flat state.
