Technical Field

[0001] This invention relates to engine cylinder blocks, and more specifically to an engine aluminum alloy cylinder block casting production line and casting method. Background Technology

[0002] After the engine aluminum alloy cylinder block is die-cast, the casting still requires three processes: removal of the gating system, heat treatment, and deburring.

[0027] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] like Figure 1The diagram shows an engine aluminum alloy cylinder block casting production line, comprising multiple die-casting units 2, a heat treatment unit 3, a post-treatment unit 4, a first conveyor line 1 extending in the left-right direction, and a second conveyor line 7 extending in the left-right direction. The multiple die-casting units 2 and the heat treatment unit 3 are arranged beside the first conveyor line 1, with the heat treatment unit 3 located downstream of the multiple die-casting units 2. The multiple die-casting units 2 are arranged sequentially at intervals in the left-right direction. The first conveyor line 1 is used to transport the castings output from the multiple die-casting units 2 to the heat treatment unit 3. The heat treatment unit 3 and the post-treatment unit 4 are both arranged beside the second conveyor line 7, with the post-treatment unit 4 located downstream of the heat treatment unit 3. The second conveyor line 7 is used to transport the castings output from the heat treatment unit 3 to the post-treatment unit 4. By adopting the above technical solution and arranging multiple die-casting units 2, when a device in a die-casting unit 2 malfunctions or needs to be repaired, the other die-casting units 2 can work normally, which can reduce or eliminate the problem of the entire line stopping production due to the failure of a certain piece of equipment; by using the first conveyor line 1 and the second conveyor line 7 to transport castings between units, the automation level of the engine aluminum alloy cylinder block casting production line is improved.

[0030] In some embodiments, the first conveyor line 1 is located in front of the plurality of die-casting units 2 and the plurality of heat treatment units 3, and the second conveyor line 7 is located behind the post-processing unit 4 and the plurality of heat treatment units 3. The above-described technical solution features a reasonable layout and saves space.

[0031] In some embodiments, such as Figure 3 As shown, the heat treatment unit 3 includes a first heat treatment furnace 301 and a second heat treatment furnace 302, which are arranged side-by-side with a gap in the left-right direction. By adopting the above technical solution, and by setting up the first heat treatment furnace 301 and the second heat treatment furnace 302, if either heat treatment furnace malfunctions or needs maintenance, the other heat treatment furnace can be used to ensure the normal operation of the production line, thus mitigating or eliminating the problem of the entire line stopping production due to a single equipment failure.

[0032] As a specific example, both the first heat treatment furnace 301 and the second heat treatment furnace 302 are tunnel-type heat treatment furnaces.

[0033] As a specific example, the heat treatment unit 3 also includes a barcode scanner for distinguishing the type of castings conveyed from the first conveyor line 1; the heat treatment unit 3 also includes a first rotary table 303 for loading castings from the first conveyor line 1 to the first heat treatment furnace 301, a second rotary table 304 for loading castings from the first conveyor line 1 to the second heat treatment furnace 302, a third rotary table 305 for unloading castings output from the first heat treatment furnace 301 to the second conveyor line 7, and a fourth rotary table 306 for unloading castings output from the second heat treatment furnace 302 to the second conveyor line 7. Using rotary tables for automatic loading and unloading improves the level of automation. As a specific example, the heat treatment unit 3 includes a casting hardness sampling platform 307, a maintenance channel for inspecting the heat treatment furnace, and a first temporary casting unloading channel 308 connected downstream of the first conveyor line 1. When a casting is detected to be non-compliant, the non-compliant casting can be output through the first temporary casting unloading channel 308.

[0034] In some embodiments, such as Figure 4As shown, the post-processing unit 4 includes a first slide 401 extending in the front-back direction, a second slide 402 extending in the front-back direction, a first handling robot 403 mounted on the first slide 401, a second handling robot 404 mounted on the second slide 402, and a plurality of machining centers 407 for removing castings. The first slide 401 is arranged at intervals and side by side on the left side of the second slide 402. The plurality of machining centers 407 are respectively arranged on the left side of the first slide 401 and the right side of the second slide 402. The first handling robot 403 and the second handling robot 404 are used for loading and unloading materials for the plurality of machining centers 407. The first handling robot 403 can slide along the first slide 401, and the second handling robot 404 can slide along the second slide 402. By adopting the above technical solution and setting up multiple machining centers 407, the problem of production line shutdown due to equipment failure can be mitigated or eliminated. The use of the first slide 401, second slide 402, first handling robot 403, and second handling robot 404 for loading and unloading is characterized by reasonable layout and space saving. The post-processing unit 4 can replace manual labor to complete the burr removal work of castings. The first handling robot 403 and second handling robot 404 are used for loading and unloading castings, and multiple machining centers 407 are used for burr removal. As a specific example, the post-processing unit 4 also includes a barcode scanner for distinguishing the type of castings conveyed from the second conveyor line 7, an aluminum chip collection device 408 for collecting aluminum chips generated by the machining centers 407, a fifth rotary table 405 for receiving castings conveyed from the second conveyor line 7, and a second temporary casting unloading channel 406 connected downstream of the second conveyor line 7. As a specific example, at least three machining centers 407 are arranged sequentially at intervals in the front-back direction on the left side of the first slide rail 401 and the right side of the second slide rail 402.

[0035] In some embodiments, the engine aluminum alloy cylinder block casting production line further includes a casting framing area 5 located in front of the after-processing unit 4 and a third conveyor line 503 for conveying the castings output from the after-processing unit 4 to the casting framing area 5. Positioning the casting framing area 5 in front of the after-processing unit 4 makes efficient use of the space in front of the after-processing unit 4.

[0036] In some embodiments, the casting framing area 5 is provided with a third handling robot 505 for transporting castings from the third conveyor line 503 to the material frame. Using the third handling robot 505 for framing castings helps to improve the automation level of the engine aluminum alloy cylinder block casting production line.

[0037] In some embodiments, the third conveyor line 503 includes a first section extending in a left-right direction and a second section extending in a front-back direction. The first section is located in front of the post-processing unit 4, and the rear end of the second section connects to the right end of the first section. The third handling robot 505 is located to the left of the second section, and multiple fourth conveyor lines 506 with lengths extending in the front-back direction are arranged to the left of the third handling robot 505. The fourth conveyor lines 506 are used to convey the material frame. By adopting the above technical solution, and by reasonably setting the structure of the third conveyor line 503 and the length direction of the fourth conveyor lines 506, the arrangement space can be reasonably utilized, which facilitates the transfer of the material frame containing the casting out of the casting loading area 5. As a specific example, two sixth rotary tables 501 are provided on the first section for receiving castings output by the first handling robot 403 and castings output by the second handling robot 404, respectively. As a specific example, a seventh rotary table 502 is provided between the rear end of the second section and the right end of the first section. As a specific example, the casting framing area 5 is also equipped with an automatic framing system control panel, a manual visual inspection platform 504 for cleaning and recording casting burrs, and a third temporary casting off-line channel 507 connected downstream of the third conveyor line 503.

[0038] In some embodiments, the engine aluminum alloy cylinder block casting production line further includes a casting storage area 6 located in front of the casting loading area 5. The casting frames in the casting loading area 5 containing castings can be transferred to the casting storage area 6 by a transfer forklift 8.

[0039] In some embodiments, such as Figure 2As shown, the die-casting unit 2 includes a die-casting main unit 201, a fourth handling robot 205, a cylinder liner conveyor belt 203, a cylinder liner heater 204, a deburring device 207, a material removal device 209, a laser marking device 211, a finished product conveying channel 214, a casting transfer table 208, a fifth handling robot 210, and a core breakage inspection device 212; the die-casting main unit 201, cylinder liner heater 204, cylinder liner conveyor belt 203, deburring device 207, and casting transfer table 208 are arranged around the fourth handling robot 205. The casting transfer table 208, the material removal device 209, the laser marking device 211, the core breakage inspection device 212, and the casting conveying channel are arranged around the periphery of the fifth handling robot 210 and are all within the gripping range of the fifth handling robot 210. The output end of the finished product conveying channel 214 is connected to the first conveying line 1. In specific implementation, the output end of the finished product conveying channel 214 is connected to the first conveying line 1 through the eighth rotary table 215. Using the above technical solution, the die casting unit 2 can realize the automatic production and transfer of castings. As a specific example, the die casting unit 2 also includes a fourth temporary casting channel 213 set next to the core breakage inspection device 212, a spraying robot 202 for spraying castings, and a waste conveying area 206 for waste disposal.

[0040] Using the above-mentioned engine aluminum alloy cylinder block casting production line, the casting transmission process is as follows: Castings are produced by multiple并排 arranged die-casting units 2. The castings are transmitted by the first conveyor line 1, enter the heat treatment unit 3 through the first rotary table 303 and the second rotary table 304. After the castings complete heat treatment, they enter the post-treatment unit 4 through the third rotary table 305 and the fourth rotary table 306. After the reading device of the post-treatment unit 4 identifies the castings, they enter the fifth rotary table 405. The first handling robot 403 and the second handling robot 404 complete the feeding work of the castings. After the burrs of the castings are removed at multiple machining centers 407, the castings are taken offline through the sixth rotary table 501. The third handling robot 505 identifies the castings through the vision system and frames the castings in the casting framing area 5. The framed castings are transferred to the casting storage area 6 through a transfer forklift 8. The present invention solves the problems of how to automatically transmit the castings between the die-casting unit 2, the heat treatment unit 3, the post-treatment unit 4, and the casting framing area 5, and the shutdown of the entire line caused by the failure of a single device, which is mainly reflected in the following points: 1. The multiple-chain automatic conveyor line is adopted between each process to realize the automatic transmission of castings, replacing the conventional forklift transfer method for castings; 2. The burrs of the aluminum alloy cylinder block castings are cleaned by the equipment fully automatically instead of manually; 3. Multiple die-casting units 2 and two heat treatment furnaces are arranged side by side in an "II" shape. When a certain device fails, the other device operates normally; The multiple machining centers 407 for deburring castings are arranged in a "field" shape in parallel. When a certain machining center 407 fails or needs to be overhauled, the other machining centers 407 operate normally; 4. The overall line personnel configuration of the fully automatic production line is reduced from 26 people to 7 people.

[0041] As Figure 5 shown, the present invention also proposes a casting method for casting an engine aluminum alloy cylinder block. Using the engine aluminum alloy cylinder block casting production line described in any one of the above, it includes the following steps:

[0042] S100. At least one die-casting unit 2 among multiple die-casting units 2 casts and outputs castings;

[0043] S200. The first conveyor line 1 conveys the castings output by the die-casting unit 2 to the heat treatment unit 3;

[0044] S300. The heat treatment unit 3 performs heat treatment on the castings and outputs the heat-treated castings;

[0045] S400. The second conveyor line 7 conveys the castings output by the heat treatment unit 3 to the post-treatment unit 4;

[0046] S500. The post-treatment unit 4 performs post-treatment on the castings and outputs the post-treated castings.

[0047] In some embodiments, the casting method described above further includes the following steps: when some die casting units in a plurality of die casting units malfunction, shutting down the malfunctioning die casting unit and using other normal die casting units to cast and output castings; when one heat treatment furnace in a heat treatment unit malfunctions, shutting down the malfunctioning furnace and using other normal furnaces to heat treat the castings; when some machining centers in a post-processing unit malfunction, shutting down the malfunctioning machining centers and using other normal machining centers to deburr the castings.

[0048] When all equipment on the engine aluminum alloy cylinder block casting production line is operating normally, the above casting method includes the following steps: After the casting is ejected from the die-casting host 201, it is picked up by the fourth handling robot 205 and moved to the de-firing device 207 to complete the de-firing of the casting. The fourth handling robot 205 places the de-fired casting on the casting transfer table 205; the fifth handling robot 210 takes the casting from the casting transfer table 205 and places it on the de-firing shank device 209 to complete the de-firing of the casting. Then, the de-firing shank device grabs the casting after de-firing and sends it to the laser marking device 211 for marking. The marked casting is then placed on the core breakage inspection device 212 for core breakage detection; the fifth handling robot 210 grabs the inspected casting and sends it to the finished product conveying channel 214 to output the casting. The casting arrives at the scanning device of the heat treatment unit through the first conveyor line 1 for identification. Then, the casting enters the first heat treatment furnace 301 through the first rotary table 303 or enters the second heat treatment furnace 302 through the second rotary table 304. After heat treatment, the castings are output to the second conveyor line 7 via the third rotary table 305 or the fourth rotary table 306. The second conveyor line 7 transports the castings to the post-processing unit 4. The castings arrive at the post-processing unit 4 via the second conveyor belt 7 and are identified by a barcode scanner. Then, the castings are positioned and wait on the fifth rotary table 405. The first handling robot 403 and the second handling robot 404 sequentially pick up the castings and send them to six identical machining centers 407 for deburring. After the machining center 407 sends a completion signal, the first handling robot 403 and the second handling robot 404 unload the deburred castings and output them to the sixth rotary table 501 and the seventh rotary table 502. The castings then enter the manual visual inspection platform 504 via the third conveyor line 503. The third handling robot 505 uses a vision positioning system integrated on the robot to grasp the castings and automatically frame them. Aluminum chips generated during deburring in the post-processing unit 4 are collected by the aluminum chip collection device 408 from the six machining centers.

[0049] When a single piece of equipment fails, the casting flow process is as follows: When one die-casting unit 2 fails, all four die-casting units 2 continue to operate, and the casting logistics still follows the conventional heat treatment and post-processing routes, reducing capacity by 1 / 5; When some equipment within die-casting unit 2 fails, the logistics situation is as follows: When the deburring device 207 fails, the fourth handling robot 205 discharges the casting through the scrap channel. After manual deburring, the casting is transported to the die-casting unit through the fourth temporary casting channel 213. The fifth handling robot 210 continues to complete the removal of the material handle, laser marking, etc. The core breakage inspection process involves equipment repair via a safety gate. When the material removal device 209 or the core breakage inspection device 212 malfunctions, the signal at that location is blocked. The fourth handling robot 205 and the de-branching device 207 operate normally. De-branched castings are output through the scrap channel. The die-casting unit operates normally, and equipment repair is performed via a safety gate. After the material removal device 209 and the core breakage inspection device 212 are functioning normally, temporary castings are fed into the fourth casting temporary channel 213 to complete material removal. At this time, the de-branching device and the fourth handling robot 205 are blocked from operation. When one of the first heat treatment furnace 301 or the second heat treatment furnace 302 malfunctions, a single heat treatment furnace is used for heat treatment. This reduces capacity by half. Both die-casting units 2 are shut down to match capacity, and the post-processing unit 4 and three machining centers 407 are shut down to match capacity. Casting logistics proceed as normal. Since the processing steps of the six machining centers 407 in the post-processing unit 4 are completely identical, when one of them fails, the other five machines can still continue to operate, reducing the production capacity by 1 / 6.

[0050] The conventional personnel configuration for separating each process in existing technology is: 20 people for 5 die-casting units, 4 people for 1 heat treatment unit, and 2 people for forklift transportation. The personnel configuration for the engine aluminum alloy cylinder block casting production line proposed in this invention is: 5 people for 5 die-casting units, 0 people for 1 heat treatment unit, 2 people for 1 post-processing unit, and 0 people for forklift transportation.
