Specific embodiments

[0027] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the present invention in combination with the drawings and the descriptions of the embodiments or the prior art. Obviously, the following descriptions of the structures of the drawings are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but do not constitute a limitation to the present invention.

[0028] Embodiment:

[0029] As Figure 1-8As shown in the figure, this embodiment provides a new type of automatic die-casting island, which includes a die-casting machine 1 and a die-casting part 8. The die-casting part 8 is output through the discharge port of the die-casting machine 1. It further includes a material-removing handle device 4, which includes a frame 41. In the middle of the frame 41, there is an installation box 46. Inside the installation box 46, there is a movable cutting assembly 44 that can move left and right. On the left and right sides of the inner wall of the frame 41 and corresponding to the left and right sides of the top of the box, there are two groups of servo slides 45 symmetrically arranged. On the sliding surfaces of the servo slides 45, there are positioning clamping platforms 43 symmetrically arranged. At the discharge port of the die-casting machine 1, there is a transfer manipulator 2. The transfer manipulator 2 grabs the die-casting part 8 and places it into one of the positioning clamping platforms 43 on one side of the material-removing handle device 4 for clamping. The positioning clamping platform 43 drives through the sliding surface of the servo slide 45 to cut the handle of the die-casting part 8 through the movable cutting assembly 44. In the middle of the positioning clamping platform 43, there is a handle-breaking mechanism 47, which breaks the cut handle through the handle-breaking mechanism 47. The movable cutting assembly 44 moves left and right reciprocally to alternately cut the two die-casting parts 8 on the two positioning clamping platforms 43. On the loading and unloading sides of the frame 41, there are anti-spray safety doors 42. On the other side of the material-removing handle device 4, there is a picking manipulator 5. Near the picking manipulator 5, there are three groups of conveyor belt devices 7 arranged side by side. On the top of one of the conveyor belt devices 7, there are multiple empty placement trays 6 stacked. On the tops of the other two conveyor belt devices 7, there are several placement trays 6 filled with die-casting parts 8.

[0030] Specifically, as Figure 1-3 shown in the figure, after the molten iron is fed into the die-casting machine 1 by the ladle and cast into the die-casting part 8, the transfer manipulator 2 takes out the die-casting part 8 from the die-casting machine 1 and places it into the positioning clamping platform 43 of the material-removing handle device 4 for clamping and fixing. Then, the industrial control computer controls the movable cutting assembly 44 to start and makes the cutting saw disc 447 rotate. At the same time, the positioning clamping platform 43 is moved through the servo slide 45 and passes through the cutting saw disc 447, so as to cut both sides of the handle of the die-casting part 8. After cutting, the industrial control computer controls the handle-breaking mechanism 47 to break the cut handle and let it fall for centralized collection. During this process, the movable cutting assembly 44 will adjust its left and right horizontal movement according to the position of the positioning clamping platform 43 (there are two positioning clamping platforms 43 in the embodiment) placed by the transfer manipulator 2. The transfer manipulator 2 alternately places the die-casting parts 8 into the two positioning clamping platforms 43, and then the picking manipulator 5 on one side of the material-removing handle device 4 puts the separated die-casting parts 8 into the placement trays 6 on the conveyor belt device 7 one by one. The conveyor belt device 7 is set to three groups. The group closest to the picking manipulator 5 is set for loading the empty placement trays 6. The picking manipulator 5 puts the die-casting parts 8 into the control panel. After it is full, it is transferred to the other two conveyor belt devices 7 for discharging. The whole process is monitored by the industrial control computer, which effectively reduces the manual labor intensity, reduces the occurrence of safety accidents, and at the same time significantly improves the production efficiency of the die-casting parts 8 and increases the output of finished products.

[0031] In a preferred embodiment of the present utility model, further, the positioning and clamping table 43 includes a positioning table 431. One side of the positioning table 431 is fixedly installed on the sliding surface of the servo sliding table 45. Pressing cylinders 432 are fixedly installed on both the left and right sides of the top of the positioning table 431. A pressing rod 433 is fixedly installed at the end of the output shaft of the pressing cylinder 432. The die casting 8 is positioned and placed on the top of the positioning table 431 by the transfer manipulator 2, and the pressing rod 433 drives to press the die casting 8 on the top of the positioning table 431 through the pressing cylinder 432.

[0032] Specifically, as Figure 4 shown, the die casting 8 with a material handle is placed on the positioning table 431 of the positioning and clamping table 43 by the transfer manipulator 2 to position and place it, thereby restricting its freedom in the horizontal direction. At the same time, pressing cylinders 432 are arranged on both the left and right sides of the top of the positioning table 431. By the contraction of the pressing cylinder 432, the pressing rod 433 is driven to descend, and the top of the die casting 8 is pressed by the square part arranged at its bottom, thereby restricting its freedom in the vertical direction. The die casting 8 is completely fixed in sequence, making the workpiece firmly clamped and reliable, and increasing the safety performance of the cutting equipment.

[0033] In a preferred embodiment of the present utility model, further, the material handle breaking mechanism 47 includes a rotary cylinder 471. The rotary cylinder 471 is fixedly installed at the center of the top of the positioning table 431. A breaking plate 472 is fixedly installed at the end of the rotary shaft of the rotary cylinder 471. One side of the top of the breaking plate 472 is arranged at the bottom of the material handle in the middle of the die casting 8.

[0034] Specifically, as Figure 5 shown, by the rotation of the output shaft of the rotary cylinder 471, the breaking plate 472 arranged in a Z shape is driven to turn upwards and break the material handle, so that it falls off and is centrally collected, preventing it from scattering in the working site and causing safety accidents.

[0035] In a preferred embodiment of the present utility model, further, the wandering cutting assembly 44 includes a mounting frame 441 and a lifting cylinder 449.

[0037] Specifically, Figure 6-7 As shown, by sliding the movable cylinder 442 left and right, the connecting plate 444 is driven to slide back and forth, so that the cutting saw disk 447 installed thereon has the function of adjusting the position laterally. At the same time, the motor base 4410 of the cutting motor 446 on which the cutting saw disk 447 is installed is connected to the connecting plate 444 by vertical sliding through the third linear guide rail group 445, and the motor mounting seat is driven to move back and forth vertically by the lifting cylinder 449, so that the cutting saw disk 447 has the ability to be raised and lowered, so that the cutting saw disk 447 is driven by the lifting cylinder 449 to extend or retract into the installation box 46, and is adjusted laterally according to the upper position of the die-casting 8, and is cut, which in turn simplifies the number of equipment components, reduces the size of the equipment, reduces the equipment manufacturing cost and energy consumption, and has high advancedness and practical performance.
