Description

Technical Field

[0001] The present invention relates to the technical field of metal sheet processing, and particularly to an assembled cylinder production line and a production method. Background Art

[0002] At present, the processing process of assembled powder tank cylinder blocks is as follows: the steel plate is first manually lifted to the shearing machine by hoisting to shear the two long sides to reach the width value set in the drawing, and then manually transferred to the drilling machine to drill all the holes. The large holes need to be cut by plasma. After the hole processing is completed, it is manually transferred to the bending machine. The plate is sucked and lifted by the overhead crane and the electromagnet, placed on the bending machine to bend one side, and then the plate is manually rotated to bend the other side. After bending, it is manually transferred to the three-roll plate rolling machine, and the bent steel plate is transported to the plate rolling machine by manual hoisting and rolled into an arc. Finally, the two short angle irons are welded.

[0003] The existing processing procedures of assembled cylinder blocks are complicated, the production cycle is long, the labor intensity is high, and the production efficiency is low; the entire production process requires manual transfer and hoisting many times. The plate is large and heavy, and there are great safety hazards during the hoisting process; there are many manual operations, the probability of human error is high, and there are no traceable historical data; the equipment used in the original production of assembled cylinders is numerous, occupies a large area, the distance between the equipment is far, the transfer time is long, and the management is inconvenient; the steel plate used for assembled cylinders has a relatively thin thickness, commonly 4mm, is easy to deform, and is easily deformed after multiple transfers, affecting the product size. Before drilling the steel plate, it is necessary to draw a drilling line for positioning and then drill, with low efficiency. The hole processing undergoes two positionings, and the positioning accuracy is poor. During the product manufacturing process, human factors are involved more, the product quality is directly related to the quality of the workers, and the product consistency is poor.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0028] The following combines Figures 1 to 7 to describe the assembled cylinder production line and production method of the embodiments of the present invention.

[0029] Refer to Figure 1 , this embodiment provides an assembled cylinder production line, which includes a CNC punching machine 5, a long-side bending machine 7, a CNC coil plate machine 12 and a short-side bending machine 16 arranged in sequence. The CNC punching machine 5 first automatically punches a workpiece 19 such as a steel plate, which can replace manual scribing and drilling, improve production efficiency, and the hole positioning accuracy is more accurate than that of manual work. Then, the long-side bending machine 7 automatically bends the long side of the workpiece 19. Subsequently, the CNC coil plate machine 12 completes the coiling of the workpiece 19. Then, the short-side bending machine 16 completes the short-side bending of the workpiece 19, thereby completing the production of the assembled cylinder. By replacing the welding angle steel process with short-side bending, the welding amount can be reduced, the labor intensity can be lowered, which is beneficial to shortening the production beat and improving production efficiency.

[0030] The front side of the CNC punching machine 5 is provided with a loading displacement mechanism 2, and the loading displacement mechanism 2 extends to the entrance table surface of the CNC punching machine 5. The entrance side of the CNC punching machine 5 is provided with an entrance table surface, and the workpiece 19 moves from the entrance table surface into the punching machine for punching. The exit of the CNC punching machine 5 is provided with an exit table surface 501 for supporting and placing the workpiece 19 that moves out of the punching machine after punching. The loading displacement mechanism 2 is used to move the workpiece 19 to the entrance table surface of the CNC punching machine 5. The side of the long-edge bending machine 7 is provided with a long-edge bending displacement mechanism 8 for moving the workpiece for long-edge bending operation. The entrance end of the CNC rolling machine 12 is connected with a rolling roller table 11. The exit table surface 501 of the CNC punching machine 5 and the rolling roller table 11 are respectively within the displacement range of the long-edge bending displacement mechanism. The long-edge bending displacement mechanism 8 is used to move the workpiece 19 on the exit table surface 501 of the CNC punching machine 5 into the long-edge bending machine 7 for long-edge bending operation, and is used to place the workpiece 19 on the rolling roller table 11 of the CNC rolling machine 12 after the long-edge bending operation of the workpiece 19. The rolling roller table 11 is a conveying roller structure for conveying the workpiece 19 into the CNC rolling machine 12 for rolling operation. The side of the short-edge bending machine 16 is provided with a short-edge bending displacement mechanism 14 for moving the workpiece for short-edge bending operation. The short-edge bending displacement mechanism 14 is used to move the workpiece 19 after rolling at the exit of the CNC rolling machine 12 to the short-edge bending machine 16 for short-edge bending operation.

[0031] A prefabricated cylinder production line provided by this embodiment adopts automated production, replaces manual transfer of the workpiece 19 through a displacement mechanism, and replaces manual marking and drilling with a CNC punching machine 5, reducing the labor intensity of workers, greatly shortening the transfer process of the workpiece 19. At the same time, it changes from the existing unitized operation to production line operation, greatly shortening the production beat, which is beneficial to improving production efficiency. Moreover, the production line has a high degree of automation, significantly reducing the proportion of human factors, and is also beneficial to improving safety and product consistency.

[0032] On the basis of the above embodiment, further, refer to Figure 1, a positioning and detection table 4 is also provided on the front side of the CNC punching machine 5, and the positioning and detection table 4 is within the displacement range of the loading displacement mechanism 2. The front side of the CNC punching machine 5 is the side located before the CNC punching machine 5 along the production process. The loading displacement mechanism 2 first places the workpiece 19 on the positioning and detection table 4 for positioning and identification, finds the central positioning point of the workpiece 19, and accurately judges the position of the workpiece 19 based on the central positioning point. Then, the workpiece 19 can be sent into the CNC punching machine 5 according to the preset position, which is beneficial to ensuring the punching accuracy of the CNC punching machine 5. The positioning and detection table 4 includes a table frame and a detection element 203. The detection element 203 is fixed to the loading displacement mechanism 2 and is used for positioning and identifying the workpiece 19 on the table frame and for dimension detection. The table frame is used to support and place the workpiece 19 transferred by the loading displacement mechanism 2. The detection element 203 is arranged on the loading displacement mechanism 2 and can move within its displacement range driven by the loading displacement mechanism 2, so as to detect various parts of the workpiece 19 placed on the table frame, and the position information and comprehensive dimension information of the workpiece 19 can be obtained.

[0033] On the basis of the above embodiment, further, an exchange workbench 1 is provided on the front side of the positioning and detection table 4, and the exchange workbench 1 is within the displacement range of the loading displacement mechanism 2. The exchange workbench 1 is used to store and place the workpiece 19. The workpiece 19 to be produced is initially placed on the exchange workbench 1. The loading displacement mechanism 2 first transfers the workpiece 19 from the exchange workbench 1 to the positioning and detection table 4, and then transfers the workpiece 19 to the entrance tabletop of the CNC punching machine 5 after position recognition and dimension detection.

[0034] Specifically, the exchange workbench 1 includes two work surfaces, and both work surfaces can be used to support and place the workpiece 19, so as to ensure the continuous and stable feeding of the workpiece 19. Further, a limiting member, such as a limiting bar, is provided on the side of the work surface of the exchange workbench 1 for limiting and fixing the workpiece 19.

[0035] On the basis of the above embodiment, further, the table frame of the positioning and detection table 4 has a hollow part, and a marking machine 3 is provided below the positioning and detection table 4 at the hollow part. The marking machine 3 is correspondingly arranged below the hollow part of the positioning and detection table 4. The marking machine 3 is used to print workpiece information on the workpiece 19.

[0036] Further, the table frame of the positioning and detection table 4 is a roller track structure, that is, a plurality of roller shafts are arranged in parallel on the table frame, and the roller shafts are rotatably connected to the table frame. A hollow part is formed between adjacent roller shafts. The marking machine 3 can print information on the workpiece 19 through the gap between adjacent roller shafts. The workpiece information printed by the marking machine 3 on the workpiece 19 can include the dimension information of the workpiece 19 and the material type of the workpiece 19, etc. The dimension information of the workpiece 19 can be the dimension information detected by the positioning and detection table 4; the material type of the workpiece 19 can be the material type input by the operator.

[0037] On the basis of the above embodiments, further, a blanking displacement mechanism 6 is provided corresponding to the outlet table 501 of the CNC punching machine 5, and the blanking displacement mechanism 6 extends to within the displacement range of the long-side bending displacement mechanism 8. The blanking displacement mechanism 6 is connected between the outlet of the CNC punching machine 5 and the long-side bending displacement mechanism 8. After the workpiece 19 is punched by the CNC punching machine 5, it first moves along the outlet table 501 through the blanking displacement mechanism 6. When it moves to within the displacement range of the long-side bending displacement mechanism 8, the long-side bending displacement mechanism 8 drives it to perform the long-side bending operation.

[0038] By providing the blanking displacement mechanism 6, the workpiece 19 can be first pulled out of the CNC punching machine 5, so that the workpiece 19 is exposed on the outlet table 501 of the CNC punching machine 5, which is convenient for the long-side bending displacement mechanism 8 to adsorb and fix the workpiece 19; at the same time, the displacement span of the long-side bending displacement mechanism 8 can be reduced.

[0039] Specifically, referring to Figure 2 , the blanking displacement mechanism 6 includes a blanking displacement component arranged along the outlet table 501 of the CNC punching machine 5 and a jaw component 602 connected to the blanking displacement component. The blanking displacement component is arranged on the side of the outlet table 501 along the moving direction of the workpiece 19 of the CNC punching machine 5. The jaw component 602 is used to clamp the side of the workpiece 19. Specifically, referring to Figure 2 , in this embodiment, the blanking displacement component includes a blanking support 601 arranged on the side of the outlet table 501 of the CNC punching machine 5. The jaw component 602 is connected to a jaw support 604, and the jaw support 604 is slidably connected to the blanking support 601 along the moving direction of the workpiece 19 of the CNC punching machine 5. A blanking guide rail 603 can be arranged on the blanking support 601 along the moving direction of the workpiece 19 of the CNC punching machine 5, and the jaw support 604 is slidably connected to the blanking guide rail 603. The jaw component 602 can include a plurality of jaws arranged side by side.

[0040] When the CNC punching machine 5 finishes punching the workpiece 19, the jaw component 602 can be driven to move towards the outlet of the CNC punching machine 5, and the side of the workpiece 19 is clamped by the jaw component 602. Then the jaw component 602 is driven to move in the direction away from the outlet of the CNC punching machine 5, so that under the pulling of the jaw component 602, the workpiece 19 moves away from the outlet of the CNC punching machine 5. The workpiece 19 is pulled out by the blanking displacement mechanism 6 and placed on the outlet table 501 and within the displacement range of the long-side bending displacement mechanism 8, which is convenient for the long-side bending displacement mechanism 8 to suck the workpiece 19.

[0041] On the basis of the above embodiments, further, referring to Figure 3, there is a roller table positioning station 9 at 7 places of the long-side bending machine. The roller table positioning station 9 is used to position and identify the workpiece 19 before the long-side bending operation. The roller table positioning station 9 is arranged within the displacement range of the long-side bending displacement mechanism 8. When the punching of the workpiece 19 is completed, the long-side bending displacement mechanism 8 first moves the workpiece 19 to the roller table positioning station 9 for positioning and identification, and then moves the workpiece 19 to the long-side bending machine 7 according to the positioning of the workpiece 19 for the long-side bending operation at a preset position.

[0042] Reference Figure 3 , the roller table positioning station 9 is of a roller table surface structure. A detection element 203 is also arranged on the roller table positioning station 9 or the long-side bending displacement mechanism 8, which is used to identify and position the workpiece 19 on the roller table positioning station 9 to obtain the real-time positioning of the workpiece 19. Preferably, the roller table positioning station 9 is arranged along the numerical control punching machine 5 at the end of the numerical control punching machine 5; the long-side bending machine 7 is arranged on one side of the roller table positioning station 9, and the long-side bending displacement mechanism 8 is arranged on the other side of the roller table positioning station 9.

[0043] On the basis of the above embodiments, further, reference Figure 1 , there is an auxiliary bracket 13 at the outlet of the numerical control rolling machine. The auxiliary bracket 13 is arranged within the displacement range of the short-side bending displacement mechanism 14. The long-side bending displacement mechanism 8 sends the workpiece 19 after the long-side bending operation to the rolling roller table 11. The rolling roller table 11 is of a conveying roller structure, which is used to convey the workpiece 19 into the rolling machine for rolling. Among them, the bent part of the long side of the workpiece 19 is located on both sides of the rolling roller table 11 and the rolling machine and does not enter the rolling machine for rolling. At the same time, the bent parts on both sides can also play a limiting role.

[0044] The auxiliary bracket 13 is arranged at the outlet of the rolling machine and is used to support and place the workpiece 19 after being rolled by the rolling machine. The short-side bending displacement mechanism 14 sucks the workpiece 19 from the auxiliary bracket 13 and then drives the workpiece 19 to move for short-side bending. The auxiliary bracket 13 is of a frame structure and has multiple hollow parts. The specific form is not limited, aiming to be able to support the rolled workpiece 19 and facilitate the short-side bending displacement mechanism 14 to remove the workpiece 19.

[0045] On the basis of the above embodiments, further, the loading displacement mechanism 2 includes a loading displacement component, the long-side bending displacement mechanism 8 includes a long-side bending displacement component, and the short-side bending displacement mechanism 14 includes a short-side bending displacement component; an adsorption structure for adsorbing and fixing the workpiece 19 is respectively connected to the loading displacement component, the long-side bending displacement component and the short-side bending displacement component. The displacement component is used to provide spatial displacement; the adsorption structure is used to adsorb and fix the workpiece 19; the displacement component can drive the adsorption structure to move in space. By sucking and fixing the workpiece 19 through the adsorption structure, damage to the surface of the workpiece 19 can be avoided.

[0046] The adsorption structure includes a negative pressure suction cup and / or an electromagnetic suction cup. Preferably, both a negative pressure suction cup and an electromagnetic suction cup are provided on each displacement component. This can improve the reliability of sucking the workpiece 19, avoid the workpiece 19 from falling due to sudden situations such as insufficient air pressure causing the failure of the negative pressure suction cup, and improve safety.

[0047] On the basis of the above embodiments, further, a tooling rack is respectively connected to the loading displacement component, the long-side bending displacement component, and the short-side bending displacement component, and an adsorption structure is provided on the tooling rack. Multiple adsorption structures can be arranged in an array on the tooling rack, which is beneficial to increasing the adsorption area of the workpiece 19 and improving the adsorption stability and reliability. And the tooling rack connected to the short-side bending displacement component is arc-shaped. Refer to Figure 4 , since the workpiece 19 is formed into an arc shape through rolling during the short-side bending process, setting the short-side bending tooling rack 15 to be arc-shaped can better adapt to the curvature of the workpiece 19, which is beneficial to firmly and stably adsorb and fix the workpiece 19.

[0048] Further, the loading tooling rack 201 on the loading displacement mechanism 2 and the long-side bending tooling rack 10 on the long-side bending displacement mechanism 8 can be planar structures.

[0049] Further, refer to Figure 1 , a terminal conveying mechanism 18 is provided at the rear side of the short-side bending machine 16, and one end of the terminal conveying mechanism 18 is located within the displacement range of the short-side bending displacement mechanism 14. The short-side bending displacement mechanism 14 drives the rolled workpiece 19 to perform short-side bending operations, and then places the finished product 17 on the terminal conveying mechanism 18 for output of the finished product 17.

[0050] Further, refer to Figure 5 , the detection element 203 of the positioning and detection table 4 can be connected to the loading tooling rack 201 of the loading displacement mechanism 2. The loading displacement mechanism 2 can drive the loading tooling rack 201 and then drive the detection element 203 to move within the displacement range of the loading displacement mechanism 2, so as to detect different parts of the workpiece 19 and obtain the dimensional information of each side of the workpiece 19. Further, a detection support 202 can be connected to the loading tooling rack 201, and the detection element 203 can be slidably connected to the detection support 202. This can increase the displacement range of the detection element 203 and facilitate comprehensive detection of the workpiece 19.

[0051] Further, refer to Figure 6 and Figure 7, a detection guide rail 204 is provided along the length direction of the detection support 202 on the detection support 202. The detection element 203 is slidably connected to the detection guide rail 204, and the detection element 203 is connected with a driving structure for driving the detection element 203 to move along the detection guide rail 204. Specifically, the driving structure can be a driving member 205 and a synchronous belt 206 structure. The detection element 203 is connected to the synchronous belt 206, and the driving member 205 can be a driving motor for driving the synchronous belt 206 to move, thereby driving the detection element 203 to move. Further, the detection element 203 can be a vision camera and / or a laser sensor; for the purpose of realizing the positioning and dimension detection of the workpiece 19, it is not specifically limited. When positioning and identifying the workpiece 19, the relative position relationship between the workpiece 19 and the positioning detection table 4 can be obtained by using the detection element 203, and then the positioning of the workpiece 19 can be obtained according to the position of the positioning detection table 4.

[0052] Further, the loading displacement mechanism 2, the long-side bending displacement mechanism 8, and the short-side bending displacement mechanism 14 can be respectively a truss robotic arm structure or a robot structure for providing spatial movement with multiple degrees of freedom. The specific setting can be determined according to the actual needs of the process and is not limited. Specifically, the loading displacement mechanism 2 is used to realize the transfer of the workpiece 19 between the exchange workbench 1, the positioning detection table 4, and the entrance tabletop of the CNC punching machine 5, and can be a three-dimensional spatial displacement structure. On the basis of realizing the transfer of the workpiece 19, the long-side bending displacement mechanism 8 is also used to send the workpiece 19 into the long-side bending machine 7 for long-side bending operation; and the long-side bending operation involves the bending of the two long sides of the workpiece 19, and the workpiece 19 needs to be flipped. Therefore, the long-side bending displacement mechanism 8 can be set as a six-axis spatial displacement mechanism, that is, it can realize six degrees of freedom of movement to meet the requirements of the long-side bending process. Specifically, the displacement component of the long-side bending displacement mechanism 8 can include a three-dimensional linear displacement component and a three-dimensional angular swing component connected to the three-dimensional linear displacement component. The short-side bending displacement mechanism 14 is similar to the long-side bending displacement mechanism 8 and can also be a six-axis spatial displacement mechanism.

[0053] On the basis of the above embodiments, further, this embodiment provides an assembled cylinder production method based on the assembled cylinder production line described in any of the above embodiments. The assembled cylinder production method includes: detecting and obtaining the actual size of the workpiece 19 and determining the central positioning point of the workpiece; when the actual size of the workpiece 19 meets the preset range, taking the central positioning point of the workpiece as a reference, sequentially performing punching, long-side bending, rolling, and short-side bending processes on the workpiece 19, and adaptively adjusting the bending amount in the long-side bending and short-side bending processes according to the deviation between the actual size and the preset size of the workpiece 19.

[0054] The production method of the assembled cylinder body provided by this embodiment detects the actual size of the workpiece 19 before performing the process operations, and then makes adaptive adjustments to the subsequent processes according to the actual size of the workpiece 19, which can replace manual measurement and shearing operations, is beneficial to reducing labor intensity, improving production efficiency, enhancing safety, improving production accuracy and improving product consistency. While detecting the actual size of the workpiece 19, the production method of the assembled cylinder body also positions the workpiece 19, obtains the position information of the workpiece 19, and then obtains the central positioning point of the workpiece 19, and transfers the workpiece to the next process based on the central positioning point and performs subsequent process operations based on the central positioning point. Specifically, the central positioning point of the workpiece 19 can be made to correspond to the central point in the subsequent process operations for subsequent operations to ensure the accuracy of the workpiece position. The production method of the assembled cylinder body can use the raw material of the fixed-length workpiece 19, improve the qualification rate of the size of the raw material of the workpiece 19, and cancel the shearing operation.

[0055] Making adaptive adjustments to the bending amount in the long-side bending and short-side bending processes according to the deviation between the actual size and the preset size of the workpiece 19 specifically includes: taking the central positioning point of the workpiece 19 as the reference, when the width of the workpiece 19 is greater than or less than the preset width, correspondingly increasing or decreasing the long-side folding size. That is, when the actual size of the workpiece 19 is within the preset range, the actual size of the workpiece 19 is further compared and analyzed with the preset size. When the actual width of the workpiece 19 is wider than the preset width, the long-side bending amount can be appropriately increased in the long-side bending process; when the actual width of the workpiece 19 is less than the preset width, the long-side bending amount can be appropriately decreased in the long-side bending process to ensure that the width of the workpiece 19 after long-side bending meets the preset width.

[0056] Taking the central positioning point of the workpiece 19 as the reference, when the length of the workpiece 19 is greater than or less than the preset length, correspondingly increasing or decreasing the short-side folding size. When the actual length of the workpiece 19 is longer than the preset length, the short-side bending amount can be appropriately increased in the short-side bending process; when the actual length of the workpiece 19 is less than the preset length, the short-side bending amount can be appropriately decreased in the short-side bending process to ensure that the length of the workpiece 19 after short-side bending meets the preset length.

[0057] Furthermore, when the actual size of the workpiece 19 obtained in the initial detection is not within the preset range, the subsequent processes are not started. That is, at this time, it is judged that the workpiece 19 does not meet the production requirements, and the workpiece 19 needs to be removed from the production line to avoid producing unqualified products. An alarm prompt can also be given at this time to remind to remove the workpiece 19 that does not meet the requirements.

[0058] Furthermore, an assembled cylinder production line provided in this embodiment further includes a general control console, which is respectively connected to the positioning and detection table 4, each displacement mechanism, a CNC turret punch press 5, a long-edge bending machine 7, a plate rolling machine, and a short-edge bending machine 16, and is used to realize the overall intelligent control of the production line.

[0059] Based on the above embodiment, further, referring to Figure 1 , this embodiment provides an automated assembled powder tank cylinder flexible production line and a production method. The production line and the production method are specifically as follows: The electric exchange workbench 1 and the truss loading manipulator, i.e., the loading displacement mechanism 2, can realize the automatic loading and transfer of raw materials, replacing manual labor, reducing labor intensity, and improving production efficiency; the positioning and detection table 4 can directly measure the size of the raw material steel plate, and the measurement accuracy can reach ±0.1 mm, replacing manual measurement and improving the measurement accuracy; the CNC turret punch press combined with the punch press unloading manipulator, i.e., the unloading displacement mechanism 6, can realize automatic punching, replacing manual scribing and drilling, improving production efficiency, and the hole positioning accuracy is more accurate than that of manual work.

[0060] The CNC plate rolling machine 12 and the plate rolling machine auxiliary bracket 13 are responsible for completing the rolling of the steel plate, replacing the manual plate rolling process, with light labor and high efficiency. The 6-axis truss hemming manipulator, i.e., the short-edge bending displacement mechanism 14, combined with the CNC short-edge hemming machine completes the short-edge bending of the powder tank cylinder, replacing the welding angle steel process, reducing the welding amount, lowering the labor intensity, and shortening the production cycle. According to the cutting size of the powder tank cylinder, the steel plate is specified in size, and the cut-to-size steel plate is purchased, canceling the shearing process.

[0061] The specific production process of this production line is as follows: The operator places steel plates of different specifications on the electric exchange platform through a crane or a forklift, selects the corresponding raw materials according to the program, that is, inputs the determined raw material type into the production line; the punch press loading manipulator automatically sucks the steel plate and places it on the positioning and detection table 4, detects the error between the width and length of the steel plate and the standard steel plate, and transmits the detection data to all subsequent equipment. After the detection is completed, the marking machine 3 works to print the raw material and workpiece 19 information in the specified area of the steel plate; after the marking is completed, the punch press loading manipulator sends the steel plate to the CNC turret punch press for stamping. After the stamping is completed, the punch press unloading manipulator transfers the steel plate to the starting position of the long-edge bending; the 7-axis truss bending manipulator moves to the starting position of the bending, the long-edge bending tooling rack 10 sucks the steel plate, places the steel plate on the roller path positioning table 9 for secondary positioning. After the positioning is completed, the long-edge bending tooling rack 10 sucks the steel plate and bends the two long edges on the CNC bending machine.

[0062] After the long-side bending is completed, the bending robotic arm transports the sheet metal to the roller table of the plate rolling machine. The roller table rotates to feed the sheet metal into the CNC plate rolling machine for rolling and forming. After the rolling is completed, the auxiliary bracket 13 of the plate rolling machine supports the arc-shaped sheet metal. The 6-axis truss flanging robotic arm sucks the arc-shaped sheet on the auxiliary bracket 13 of the plate rolling machine through the arc flanging tooling fixture, i.e., the short-side bending tooling fixture 15, and places it on the CNC flanging machine to fold the two short sides. After the flanging, the final product is completed. The flanging robotic arm places the finished product 17 on the end roller table and transfers it to the next process of welding and bending the edges.

[0063] This production line and production method are beneficial to reducing labor intensity: The assembled powder tank cylinder production line adopts automated production. Trusses and robotic arms are used to replace workers for loading and unloading, bending, and plate rolling, and punches and loading robotic arms are used to replace workers for marking and drilling, reducing the labor intensity of workers and improving the safety factor. For example, previously, more than 12 people were required for each shift of production, but now only 3 - 4 people are needed for raw material supply and finished product 17 transfer.

[0064] Improving production efficiency: The production process of the assembled powder tank cylinder fully adopts mechanical automation operations, greatly reducing the product transfer process. Punching replaces drilling, improving production efficiency. According to the processing technological process, the main equipment is integrated into a production line, and at the same time, the original unitized operation is changed to production line operation, shortening the transfer distance. Combining with the truss robotic arm, the operation rhythm is improved, greatly shortening the production rhythm and improving production efficiency. For example, previously 30 pieces were produced per shift, but now 80 pieces are produced per shift, and the production efficiency has increased by 267%.

[0065] Improving safety: The transfer and loading and unloading of sheet metal are all completed by the truss robotic arm, avoiding safety accidents that occur during manual operations. Improving precision: Previously, the dimensions of the steel plate were measured and positioned by workers, and the interference of human factors was large, and the dimensional accuracy control was low. Now, automatic measurement is realized through the positioning detection table 4, and the positioning accuracy can be controlled within ±0.1 mm, greatly improving the dimensional accuracy. The original processing holes required two processes of marking and drilling, and the secondary positioning would cause large hole position deviations. Now, the CNC punch 5 is used for one-time processing, and the hole position can be controlled within ±0.1 mm, with high positioning accuracy.

[0066] Integrated site for convenient management: The production of the assembled powder tank cylinder body has changed from the original 4 independent devices to the current automated production line. The distance between the devices has been shortened, and the overall floor area has been reduced by more than half compared to the original, making management more convenient. The assembled powder tank cylinder body production line uses truss robotic arms for all transfers. The suction cups are fixed on the steel plate without damaging the steel plate, ensuring the quality of the product. Substantial reduction in production costs: Previously, after the steel plates were returned to the factory, they needed to be sheared, drilled, and finally angle irons were welded. Now, fixed-length steel plates are used without any leftover tailings, greatly improving the material utilization rate. By restricting the fixed length of the raw materials, the shearing process can be cancelled. The punching process forms in one step instead of drilling, significantly reducing the working hours and labor costs. Design optimization: The two short sides are directly flanged, and four small corners are welded, eliminating the need for welding angle irons and reducing the welding workload. Data is recorded for each process in the production process of the powder tank cylinder body. The system can store and trace the processing data, always ensuring the quality of the product. The assembled powder tank cylinder body production line has a high degree of automation, significantly reducing the proportion of human factors and greatly improving the product consistency.

[0067] Robots can be used to replace the truss robotic arms to achieve the transfer of workpiece 19. The entire automated assembled powder tank cylinder body flexible production line can achieve the automated production of the assembled powder tank cylinder body blocks, and this processing technology is leading. The entire automated assembled powder tank cylinder body flexible production line can automatically complete the measurement and positioning of the steel plate size through the positioning table, with an accuracy within ±0.1 mm, which is the basis for the subsequent sheet metal processing and positioning. The rolling unit (CNC rolling machine 12, rolling machine roller table, rolling machine auxiliary bracket 13) can automatically complete the rolling action of the sheet metal, and the rolling unit can be connected to the truss robotic arm to complete the material transfer. The 7-axis truss robotic arm can complete the automatic loading and unloading and transfer of the sheet metal. Combined with the CNC bending machine, it can achieve the bending action of the sheet metal at any angle without secondary grasping.
