Description

Technical Field

[0001] The invention belongs to the field of milling processing. Background Art

[0002] See aluminum ingots such as Figure 1 As shown, it is a flat and long structure with eight circumferential sides. When the milling process is implemented on the eight sides, all eight sides of the aluminum ingot need to be milled. Since the aluminum ingot needs a supporting structure to contact the surface of the aluminum ingot during the milling process, the eight sides of the aluminum ingot cannot be milled at the same time. Since the aluminum ingot itself is huge and difficult to turn over, it is necessary to design a device that can automatically perform complete milling on the eight sides of the aluminum ingot. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a combined unit and working method for automatically milling eight sides of an aluminum ingot, which can realize the automated combined milling process for the eight sides of the aluminum ingot.

[0004] Technical solution: To achieve the above purpose, the present invention provides a combined unit for automatically milling eight sides of aluminum ingots, comprising a first track, a second track, and a first turning unit; the first milling unit and the second milling unit are respectively located on both sides of the first track; the third milling unit and the fourth milling unit are respectively located on both sides of the second track;

[0005] A first slide and a second slide are respectively arranged on the first track and the second track which are parallel to each other; the first flip unit is located at the end of the first track, and the first flip unit is also located at one side of the second track;

[0006] When the first slide moves along the first track to the position closest to the first flip unit, the aluminum ingot to be processed carried by the first slide can be translated along the length direction to transition to the first flip unit;

[0007] When the second slide moves along the second track to one side of the first flip unit, the first flip unit can flip the aluminum ingot to be processed carried by itself 90° toward the second slide and onto the second slide.

[0008] Furthermore, the first milling unit and the second milling unit are on both sides of the first track; the first milling unit includes a first milling machine, a second milling machine and a third milling machine distributed from top to bottom; the second milling unit includes a fourth milling machine, a fifth milling machine and a sixth milling machine distributed from top to bottom.

[0009] Furthermore, the second processing plane of the aluminum ingot to be processed carried on the second slide faces downward; the third milling unit and the fourth milling unit are symmetrical on both sides of the second track; the third milling unit includes a seventh milling machine; and the fourth milling unit includes an eighth milling machine.

[0010] Furthermore, a direction that is horizontal and perpendicular to the length direction of the first track is defined as the Y direction; a plurality of roller bases are fixedly arranged in an array along the length direction on the first slide; at least one pair of active rollers are arranged at the upper end of each roller base, and the axis of each active roller is parallel to the Y direction; the active rollers on the plurality of roller bases jointly lift up the horizontal aluminum ingot to be processed; the driving device can drive the active rollers to actively rotate, thereby causing the aluminum ingot to be processed to translate relative to the first slide along the length direction of the first track.

[0011] Furthermore, the first flipping unit includes a base, a horizontal flipping platform is supported on the upper side of the base, and a plurality of workpiece-carrying rollers with axes in the Y direction are arranged in an array on the upper side of the flipping platform; the end of the flipping platform close to the first track is hinged to the base through a first hinge, and also includes an oblique hydraulic telescope, the upper end of the oblique hydraulic telescope is hinged to the end of the flipping platform away from the first track through a second hinge, and the lower end of the hydraulic telescope is hinged to the base through a third hinge; the third hinge is located below between the first hinge and the second hinge; when the hydraulic telescope gradually extends, the flipping platform flips upward around the first hinge.

[0012] Furthermore, the workpiece carrying roller is at the same height as each active roller support wheel on the first slide.

[0013] Furthermore, a pair of upwardly extending anti-lateral displacement limit piles are fixedly connected to the upper side of one end of the flip platform close to the first hinged member.

[0014] Furthermore, at least one pair of a pushers is fixedly arranged on the flip platform. When the flip platform is horizontal, the pushing direction of the a pushers is upward, and in a top-down view, as shown in the figure, each a pusher is below the gap between two adjacent workpiece-bearing rollers.

[0015] Furthermore, two pairs of b pushers are arranged opposite to each other and extend along the Y direction on both sides of the first track away from one end of the first flip unit; and a pair of c pushers are arranged on one side of the second track away from the first flip unit, extending along the Y direction and with the pushing direction toward the first flip unit.

[0016] Further, the working method of the combined unit for automatically milling eight sides of the aluminum ingot is as follows: Step 1, placing the aluminum ingot to be processed on the first slide;

[0017] Step 2, controlling the aluminum ingot to be processed on the first slide to gradually pass through between the first milling unit and the second milling unit along the first track path, so as to perform plane milling on the first to-be-processed plane, the second to-be-processed plane, the third to-be-processed plane, the fourth to-be-processed plane, the fifth to-be-processed plane and the sixth to-be-processed plane of the aluminum ingot to be processed;

[0018] The first slide is controlled to translate along the first track to the position closest to the first flip unit; then, each active roller on the first slide, which is originally in a braking state, is driven to rotate synchronously and actively, and driven by the rolling friction of each active roller, the aluminum ingot to be processed translates relative to the first slide along the length direction of the first track toward the direction close to the first flip unit, until the aluminum ingot to be processed smoothly transitions from the first slide to the first flip unit;

[0019] Step 3, controlling the second slide to translate along the second track to one side of the first flip unit, so that the second slide corresponds to the flip platform;

[0020] Step 4: Control the hydraulic expansion joint on the first flip unit to gradually extend until the flip platform flips the aluminum ingot to be processed upward by 90° around the first hinge, and the original vertical pusher a becomes extended along the Y direction, and at this time, the pusher a and the pusher c are in a relative state; at the same time, the aluminum ingot to be processed that has been flipped upward by 90° around the first hinge has reached the gantry on the second slide and is supported by the second slide, and at this time, the second surface to be processed of the aluminum ingot to be processed faces downward; at this time, the aluminum ingot to be processed is between the pusher a and the pusher c, and the aluminum ingot to be processed is finely translated in the Y direction through the cooperation of the pushers a and c on both sides of the aluminum ingot to be processed, so that the center line of the aluminum ingot to be processed in the top view coincides with the center line of the second slide;

[0021] Step six, control the second slide and the aluminum ingot to be processed on the second slide to gradually pass through the third milling unit and the fourth milling unit along the second track path. In the process of the aluminum ingot to be processed gradually passing through the third milling unit and the fourth milling unit along the second track path, the milling ends of the seventh milling machine and the eighth milling machine respectively perform plane milling on the seventh to-be-processed plane and the eighth to-be-processed plane of the aluminum ingot to be processed carried on the second slide; finally, the milling process of the eight surfaces of the aluminum ingot to be processed is completed.

[0022] Beneficial effect: The present invention can realize the automatic joint milling process of the eight sides of the aluminum ingot. In "step four", the turning platform turns the aluminum ingot to be processed upward by 90° around the first hinge, and the original vertical pusher a becomes extended along the Y direction, so that the pusher a and the pusher c are in a relative state; at the same time, the aluminum ingot to be processed that is turned upward by 90° around the first hinge has reached the gantry on the second slide and is supported by the second slide, and at this time, the second surface to be processed of the aluminum ingot to be processed faces downward; the aluminum ingot to be processed is between the pusher a and the pusher c, and the aluminum ingot to be processed is finely translated in the Y direction through the cooperation of the pushers a and c on both sides of the aluminum ingot to be processed, so that the center line of the aluminum ingot to be processed in the top view coincides with the center line of the second slide, thereby achieving the purpose of smoothly switching the milling surface.

[0041] Let the direction which is horizontal and perpendicular to the length direction of the first track 1 be the Y direction;

[0042] like Fig.10 As shown, a plurality of roller bases 63 are fixedly arranged in an array along the length direction on the first slide 4; at least a pair of active rollers 63 are arranged at the upper end of each roller base 63, and the axis of each active roller 63 is parallel to the Y direction; the active rollers 63 on the plurality of roller bases 63 jointly lift up the horizontal aluminum ingot 2 to be processed; the driving device can drive the active rollers 63 to actively rotate, so that the aluminum ingot 2 to be processed can be translated relative to the first slide 4 along the length direction of the first track 1.

[0043] like Figure 5 , 6 7. The first flip unit 11 includes a base 32, and a horizontal flip platform 25 is supported on the upper side of the base 32. A plurality of workpiece-carrying rollers 24 with axes in the Y direction are arranged in an array on the upper side of the flip platform 25. The workpiece-carrying rollers 24 are at the same height as the active rollers 63 on the first slide 4. The end of the flip platform 25 close to the first track 1 is hinged to the base 32 through a first hinge 29, and also includes an oblique hydraulic telescope 27. The upper end of the oblique hydraulic telescope 27 is hinged to the end of the flip platform 25 away from the first track 1 through a second hinge 26, and the lower end of the hydraulic telescope 27 is hinged to the base 32 through a third hinge 28. The third hinge 28 is located below the first hinge 29 and the second hinge 26. When the hydraulic telescope 27 is gradually extended, the flip platform 25 flips upward around the first hinge 29. A pair of upwardly extending anti-lateral displacement limit piles 33 are fixedly connected to the upper side of the end of the flip platform 25 close to the first hinge 29.

[0044] At least one pair of pushers 30 is fixedly arranged on the flip platform 25. When the flip platform 25 is horizontal, the pusher 30 is facing upward, and in a top-down perspective, Figure 7 Each ejector 30 is below the gap between two adjacent workpiece carrying rollers 24.

[0045] like Figure 2As shown: two pairs of pushers b 17 are arranged opposite to each other and extend along the Y direction on both sides of the first track 1 away from the first flip unit 11; a pair of pushers c 15 are arranged on the side of the second track 14 away from the first flip unit 11 and extend along the Y direction, with the push direction facing the first flip unit 11; a pusher d 12 is arranged on the side of the second track 14 away from the second flip unit 20 and extends along the Y direction, with the push direction facing the second flip unit 20.

[0046] like Fig. 9 A gantry 22 is fixedly installed on the second slide 21, and the aluminum ingot 2 to be processed carried by the second slide 21 is on the inner side of the gantry 22; a plurality of e pushers 23 with a downward pushing direction are fixed on the top frame of the gantry 22, and the downward extension of the plurality of e pushers 23 plays a clamping role.

[0047] The working process and working principle of this scheme: Step 1, in the initial state, the first slide 4 is at the end of the first track 1 away from the first flip unit 11, and the aluminum ingot 2 to be processed after rough processing is placed on the first slide 4 along the length direction through the lifting mechanism, and the active rollers 63 on the plurality of roller bases 63 placed on the first slide 4 jointly lift the horizontal aluminum ingot 2 to be processed upwards, and at this time, the eighth processing plane 2h of the aluminum ingot 2 to be processed carried on the first slide 4 faces downward; then, through the cooperation of the two pairs of b pushers 17 on both sides of the aluminum ingot 2 to be processed, the aluminum ingot 2 to be processed is finely adjusted in the Y direction, so that the center line of the aluminum ingot 2 to be processed in the top view coincides with the center line of the first slide 4;

[0048] Step 2, controlling the first slide 4 and the aluminum ingot 2 to be processed on the first slide 4 to gradually pass through between the first milling unit 16 and the second milling unit 18 along the path of the first track 1;

[0049] In the process that the aluminum ingot 2 to be processed gradually passes between the first milling unit 16 and the second milling unit 18 along the path of the first track 1, the milling ends 5 of the first milling machine 6a, the second milling machine 6b, the third milling machine 6c, the fourth milling machine 6d, the fifth milling machine 6e and the sixth milling machine 6f respectively perform plane milling on the first to-be-processed plane 2a, the second to-be-processed plane 2b, the third to-be-processed plane 2c, the fourth to-be-processed plane 2d, the fifth to-be-processed plane 2e and the sixth to-be-processed plane 2f of the aluminum ingot 2 to be processed carried on the first slide 4;

[0050] After completing the milling of the first plane 2a to be processed, the second plane 2b to be processed, the third plane 2c to be processed, the fourth plane 2d to be processed, the fifth plane 2e to be processed and the sixth plane 2f to be processed, the first slide 4 is controlled to translate along the first track 1 to the position closest to the first flip unit 11; then the active rollers 63 on the first slide 4 which was originally in the braking state are driven to rotate synchronously and actively, and driven by the rolling friction of the active rollers 63, the aluminum ingot 2 to be processed slowly translates relative to the first slide 4 along the length direction of the first track 1 toward the first flip unit 11, until the aluminum ingot 2 to be processed smoothly transitions from the first slide 4 to the first flip unit 11, at which time the workpiece bearing rollers 24 on the first flip unit 11 jointly carry the aluminum ingot 2 to be processed;

[0051] Step 3, control the second slide 21 to translate along the second track 14 to the side of the first flip unit 11, so that the gantry 22 on the second slide 21 corresponds to the flip platform 25;

[0052] Step 4: Control the hydraulic expansion joint 27 on the first flip unit 11 to gradually extend, so that the flip platform 25 flips upward with the aluminum ingot 2 to be processed around the first hinge 29, and the anti-lateral displacement limit pile 33 prevents the aluminum ingot 2 to be processed from sliding sideways; until the flip platform 25 flips upward with the aluminum ingot 2 to be processed around the first hinge 29 by 90°, at which time the originally vertical a pusher 30 becomes extended along the Y direction, and at this time the a pusher 30 and the c pusher 15 are in a relative state; at the same time, the aluminum ingot 2 to be processed that has flipped upward by 90° around the first hinge 29 has reached the gantry 22 on the second slide 21 and is supported by the second slide 21, and at this time the second to-be-processed plane 2b of the aluminum ingot 2 to be processed faces downward;

[0053] At this time, the aluminum ingot 2 to be processed is between the a pusher 30 and the c pusher 15, and the aluminum ingot 2 to be processed is finely adjusted in the Y direction by the cooperation of the a pusher 30 and the c pusher 15 on both sides of the aluminum ingot 2 to be processed, so that the center line of the aluminum ingot 2 to be processed in a top view coincides with the center line of the second slide 21;

[0054] Step six, control the second slide 21 and the aluminum ingot 2 to be processed on the second slide 21 to gradually pass through the third milling unit 13 and the fourth milling unit 19 along the second track 14 path. In the process of the aluminum ingot 2 to be processed gradually passing through the third milling unit 13 and the fourth milling unit 19 along the second track 14 path, the milling ends 5 of the seventh milling machine 6g and the eighth milling machine 6h respectively perform plane milling on the seventh to-be-processed plane 2g and the eighth to-be-processed plane 2h of the aluminum ingot 2 to be processed carried on the second slide 21; finally, the milling process of the eight surfaces of the aluminum ingot 2 to be processed is completed.

[0055] like Figure 2A second flipping unit 20 is provided on one side of the second track 14; except that there is no workpiece carrying roller 24 on the flipping platform 25, the other structures of the second flipping unit 20 are consistent with the structure of the first flipping unit 11. The second flipping unit 20 cooperates with the pusher 12 to flip and unload the aluminum ingot 2 that has been processed on the second slide 21.

[0056] like Figures 10 to 12 The milling ends 5 of the first milling machine 6a, the second milling machine 6b, the third milling machine 6c, the fourth milling machine 6d, the fifth milling machine 6e, the sixth milling machine 6f, the seventh milling machine 6g and the eighth milling machine 6h all include a rotary cutter disc 40 driven by a rotating shaft capable of high-speed rotation. The rotary cutter disc 40 is provided with a plurality of milling cutter inserting openings 41 along the outer contour. A milling cutter head 42 is fixedly embedded in each milling cutter inserting opening 41. The two ends of the milling cutter head 42 are respectively a tail end 51 of the cutting end 49. The tail end 51 and the cutting end 49 protrude from the inner and outer disc surfaces of the rotary cutter disc 40 respectively. One side of the milling cutter head 42 is formed to extend from the cutting end 49 to the tail end 51. A chip guide surface 50 is formed on the side of the milling cutter head 42 close to the chip guide surface 50, and a chip suction channel 48 that runs through the front and rear of the rotary cutter disc 40 is formed; a fixed cutter disc guard 43 is provided on the outer periphery of the rotary cutter disc 42, a circulation air duct 11 is formed in the cutter disc guard 43, and the circulation air duct 11 is on the back side of the rotary cutter disc 42; the circulation air duct 11 is connected to a discharge pipe 45 at a position deviating from the axis of the rotary cutter disc 40; an annular back plate 46 is fixed to the back side of the cutter disc guard 43, an inner ring wall 47 coaxial with the rotary cutter disc 40 is fixed to the inner ring of the annular back plate 46, and the circulation air duct 11 is on the outer ring of the inner ring wall 47; the tail wing end 51 of each milling cutter head 42 is in the circulation air duct 11.

[0057] During the high-speed rotation of the rotary cutter head 40, the cutting end 49 of each milling cutter head 42 performs milling on the processing surface. At the same time, the tail wing end 51 of each milling cutter head 42 stirs the circulating air duct 11 to form a high-speed circulating flow. The high-speed circulating gas in the circulating air duct 11 is continuously thrown out through the discharge pipe 45 under the action of centrifugal force. According to the Bernoulli equation of fluid mechanics, the gas pressure decreases accordingly under the condition of high flow rate, so that a continuous negative pressure is formed in the circulating air duct 11, and the negative pressure is transmitted to each chip suction channel 48, so that each milling cutter head 42 The metal chips cut off by the cutting end 49 are immediately sucked into the high-speed circulating gas in the circulating air duct 11 through the chip suction channel 48 continuously and quickly under the action of the corresponding chip suction channel 48 and the smooth chip guide surface 50, thereby avoiding the problem of chips splashing outward and scratching the surface of the workpiece, and at the same time achieving the purpose of accurate chip suction. The metal chips entering the circulating air duct 11 rotate synchronously with the high-speed circulation, and finally the metal chips rotating at a high speed in the circulating air duct 11 are continuously thrown out to the chip collection device through the discharge pipe 45 under the action of centrifugal force.

[0058] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
