Description

Technical Field

[0002] Stamping is a common and widely used method for metal material processing. It forms the metal sheet into the desired geometric shape by placing it on a punch press and using the pressure applied by the punch. Stamping has the characteristics of high efficiency, high precision and good repeatability. It is widely used in various industries such as automobile manufacturing, electronic equipment, and home appliances. As an efficient and high-precision metal material processing method, stamping plays an important role in industrial manufacturing.

[0003] In the stamping processing of metal shells, most of the existing processing steps are usually to manually place the metal sheet cut to a suitable size between the upper die and the lower die of the stamping die, and then start the stamping equipment to punch the metal sheet into the required metal shell through the cooperation of the upper die and the lower die. In the prior art, the above-mentioned processing flow usually still uses manual loading and unloading, and manually lubricates the metal sheet before stamping. Manual loading and unloading is not only prone to accidental damage to the stamped parts, but also difficult to ensure the consistency of processing quality, and various accidents may occur during processing, causing injuries to the processing personnel. At the same time, manual lubrication is difficult to ensure the lubrication effect of the metal sheet, and it is easy to result in poor surface quality of the stamped parts. Summary of the invention

[0016] In addition, the present invention provides a method for a metal shell stamping part processing system, comprising the following steps:

[0017] Step 1: Pre-clean and polish the cut metal sheets of appropriate size;

[0018] Step 2: Feed the pre-treated metal sheets into the feed conveyor belt in sequence through the conveyor belt, and start the equipment through the automatic control machine;

[0019] Step 3: When the metal sheet is fed into the feed conveyor and reaches the leftmost side, the first sensor will sense the presence of the metal sheet, and the automatic control machine will start the rotating assembly on the feeding mechanism to rotate right to the upper part of the feed conveyor, and then control the rotating assembly to cooperate with the lifting assembly to move the electromagnetic absorber to the top of the metal sheet. Then, when the induction probe senses the metal sheet, the induction probe is started to absorb the metal sheet, and then the automatic control machine controls the rotating assembly, lifting assembly, and feeding assembly to cooperate to feed the metal sheet into the lower stamping die seat;

[0020] Step 4: After the metal sheet is moved to the upper side of the lower stamping die base by the cooperation of the rotating component, the lifting component, and the feeding component, the lifting component controls the electromagnetic absorber to move downward to place the metal sheet on the upper surface of the lower stamping die base and the inside of the ejection template. Then the automatic control machine controls the electromagnetic absorber to close and put the metal sheet down. Then the electric push rod on the feeding component is controlled to drive the second connecting block to retract, and the third sensor is used to check whether the metal sheet is placed correctly. If the detection is correct, the automatic control machine starts the pressure component to press the upper die component to stamp the metal sheet. If it is not correct, the automatic control machine will pause the equipment and issue an alarm to notify the processing personnel;

[0021] Step 5: While the pressure component pushes the upper die assembly downward, the upper die base drives the push components on both sides to move to both sides, and pushes the oil spray component to move at the same time. While the oil spray component moves to both sides, it sprays lubricating oil mist to lubricate the upper surface of the metal sheet to reduce the friction between the lower die assembly and the upper die assembly during the stamping process. If it is necessary to lubricate the lower stamping die seat and the ejection template on the lower die assembly, the pressure component is controlled by the automatic control machine to push the upper die assembly to perform air compression once, and the lower stamping die seat and the ejection template can be lubricated through the lubrication mechanism;

[0022] Step 6: After completing the stamping of the metal sheet, the pressure component drives the upper die component to lift up and reset, and at the same time drives the lubrication mechanism to reset. Then, the lower die component, with the cooperation of the ejection spring and the ejection template, ejects the processed metal shell stamping part out of the lower stamping die seat along the ejection guide column. Then, the automatic control machine controls the lifting assembly and the feeding assembly to move the electromagnetic absorber to the upper end of the lower stamping die seat and move downward. When the induction probe senses the metal shell stamping part, the electromagnetic absorber is started to absorb the metal shell, and the metal shell stamping part is moved to the left to the upper side of the discharge conveyor belt through the automatic control machine. After the second sensor senses the metal shell, the automatic control machine turns off the electromagnetic absorber and places the metal shell stamping part on the discharge conveyor belt, and the discharge conveyor belt sends it out of the equipment. Then, the automatic control machine controls the feeding mechanism to reset and prepare for the next stamping process cycle.

[0023] Working principle: When using the device, the metal sheets cut to appropriate sizes are first polished and cleaned for pretreatment, and then conveyed to the feed conveyor on the work surface in sequence. After the metal sheet reaches the left side of the feed conveyor, the first sensor arranged on the front side of the feed conveyor will sense the arrival of the metal sheet. Subsequently, the rotating assembly, lifting assembly, and feeding assembly on the control feeding mechanism of the automatic control machine cooperate to take the metal sheet out of the feed conveyor and send it into the stamping mechanism for stamping. When the pressure assembly pushes the upper mold assembly downward, the linkage between the upper mold assembly and the lubrication mechanism can drive the pushing assembly to move to both sides. While the pushing assembly is moving, the pushing assembly will squeeze the oil spray assembly through the internal structure, driving the oil spray assembly to spray lubricating oil mist to the metal sheet, thereby reducing the friction between the upper mold assembly and the lower mold assembly when stamping the metal sheet, thereby improving the surface quality of the metal shell stamping parts.

[0024] The present invention provides a metal shell stamping parts processing system and method thereof, which has the following beneficial effects:

[0025] 1. The present invention automatically performs loading and unloading operations through the cooperation of the rotating assembly, the lifting assembly and the feeding assembly inside the feeding mechanism, and the loading and unloading processes are fully automated through the control of the automatic control machine, without the need for manual loading and unloading. While reducing the workload of the processing personnel, it also avoids the problem of various accidents that may cause injuries to the processing personnel during processing.

[0026] 2. The present invention lubricates the metal sheet being stamped by a lubrication mechanism linked to the upper die assembly on both sides of the upper die assembly. The lubrication mechanism can ensure that the metal sheet can be fully lubricated during the stamping process, reduce the friction between the upper die assembly and the lower die assembly on the surface of the metal shell stamping part, and improve the surface quality of the metal shell stamping part.

[0027] 3. The present invention lubricates the upper die assembly and the lower die assembly of the stamping process through the lubrication mechanism linked to the upper die assembly on both sides of the upper die assembly, and when the upper die assembly and the lower die assembly need to be lubricated, the pressure assembly is started to compress the air to drive the lubrication mechanism to lubricate the upper die assembly and the lower die assembly.

[0028] 4. The present invention is provided with a third sensor to check whether the metal sheet is placed correctly during stamping. If it is detected that the placement is correct, the automatic control machine starts the stamping mechanism to press down the upper die assembly and cooperate with the lower die assembly to stamp the metal sheet, and the metal sheet is processed into a metal shell stamping part. If the third sensor detects that the placement is incorrect, the automatic control machine will pause the equipment and sound an alarm to notify the processing personnel, so as to prevent material loss and equipment damage caused by improper placement of the metal sheet.

[0041] Example:

[0042] Please refer to the attached Figure 1 - Attachment Figure 3The embodiment of the present invention provides a metal shell stamping processing system, including a work surface 1, an automatic control machine 2 is fixedly connected to the upper surface of the front right side of the work surface 1, a conveying mechanism 3 is arranged at the rear side of the automatic control machine 2, the conveying mechanism 3 includes a feeding conveyor belt 301 and a discharging conveyor belt 303, a first sensor 302 is arranged at the front side of the feeding conveyor belt 301, and a second sensor 304 is arranged at the front side of the discharging conveyor belt 303, the lower ends of the feeding conveyor belt 301, the first sensor 302, the discharging conveyor belt 303, the discharging conveyor belt 303, and the second sensor 304 are all fixedly connected to the upper surface of the work surface 1, and the first sensor 302 and the second sensor 304 are all electrically connected to the automatic control machine 2;

[0043] A feeding mechanism 4 is arranged between the feeding conveyor belt 301 and the discharging conveyor belt 303. The feeding mechanism 4 includes a rotating assembly 5, a lifting assembly 6, and a feeding assembly 7. The lower end of the rotating assembly 5 is fixedly connected to the upper surface of the work table 1, the upper end of the rotating assembly 5 is fixedly connected to the lifting assembly 6, and the interior of the lifting assembly 6 is fixedly connected to the feeding assembly 7. A stamping mechanism 8 is arranged at the rear side of the feeding mechanism 4. Under the control of the automatic control machine 2, the conveying mechanism 3 cooperates with the feeding mechanism 4 to automatically lift the metal sheet from the feeding conveyor belt 301 through the feeding mechanism 4 and feed it into the stamping mechanism 8 for stamping processing. After the processing is completed, the completed sheet is automatically sent to the stamping mechanism 8 through the feeding mechanism 4. The stamped metal shell stamping parts are taken out from the stamping mechanism 8 and put into the discharge conveyor 303 to be sent out of the equipment. Specifically, when using the device, the metal sheets cut to suitable sizes are first polished and cleaned for pretreatment, and then conveyed to the feed conveyor 301 on the work table 1 in sequence. After the metal sheets reach the left side of the feed conveyor 301, the first sensor 302 arranged on the front side of the feed conveyor 301 will sense the arrival of the metal sheet, and then the rotating component 5, the lifting component 6, and the feeding component 7 on the control feeding mechanism 4 of the automatic control machine 2 cooperate to take the metal sheet out from the feed conveyor 301 and send it into the stamping mechanism 8 for stamping processing.

[0044] Refer to the attached Figure 6 With attached Figure 8The stamping mechanism 8 includes a pressure component 9, an upper die component 10, and a lower die component 11.

During the stamping process, the upper die component 10 is pushed down by the pressure component 9 and cooperated with the lower die component 11 to stamp the metal sheet into a metal shell stamping part. At the same time, in the process of the pressure component 9 pushing the upper die component 10 down, the oil spraying components 14 will be pushed synchronously. The moving component 13 drives the oil spray component 14 to spray lubricating oil mist toward the metal sheet, thereby achieving the purpose of synchronous lubrication during stamping processing. Specifically, when the pressure component 9 pushes the upper mold component 10 to move downward, the linkage between the upper mold component 10 and the lubrication mechanism 12 can drive the pushing component 13 to move to both sides. While the pushing component 13 moves, the pushing component 13 will squeeze the oil spray component 14 through its internal structure, thereby driving the oil spray component 14 to spray lubricating oil mist toward the metal sheet, thereby reducing the friction between the upper mold component 10 and the lower mold component 11 when stamping the metal sheet, thereby improving the surface quality of the metal shell stamping parts.

[0046] Specifically, when the automatic controller 2 is used to control the feeding mechanism 4 , the automatic controller 2 controls the rotation angle of the rotating disk 502 and the rotating shaft 503 by controlling the rotation of the servo rotating base 501 , thereby controlling the specific orientation angles of the lifting assembly 6 and the feeding assembly 7 .

[0050] Specifically, after the automatic control machine 2 controls the servo rotating base 501 and the servo lifting motor 606 to drive the feeding assembly 7 to rotate to the set angle and height, the automatic control machine 2 controls the bottom plate 901 to push the second connecting block 702 to the set position. When the sensing probe 704 on the second connecting block 702 contacts and senses the metal sheet, the automatic control machine 2 starts the electromagnetic absorber 703 and energizes it to absorb the metal sheet. Subsequently, the automatic control machine 2 controls the servo rotating base 501, the sliding frame 601, the electric push rod 701, and the electromagnetic absorber 703 to cooperate with each other to send the metal sheet into the stamping mechanism 8 for stamping processing.

[0052] Specifically, after the metal sheet is fed into the stamping mechanism 8 and inspected, the automatic control machine 2 can start the hydraulic rod 904 inside the pressure assembly 9 to push the upper die assembly 10 to move downward, provide pressure for the stamping process of the upper die assembly 10 and the lower die assembly 11, and lift the upper die assembly 10 after the stamping is completed.

The lower ends of the guide columns 1003 are fixedly connected to the lower mold assembly 11.

[0054] Specifically, when the automatic control machine 2 starts the pressure assembly 9 to move downward, the hydraulic rod 904 pushes the upper mold base 1001 to move downward, and at the same time, the upper mold base 1001 will overcome the elastic force of the auxiliary spring 1004 when moving, and drive the upper stamping die base 1002 to move downward along the guide column 1003. Starting the guide column 1003 can guide the upper mold base 1001 and the upper stamping die base 1002, and the auxiliary spring 1004 can assist in resetting the upper stamping die base 1002 when resetting.

The lower surface of the lower die base 1101 is fixedly connected to the upper surface of the bottom plate 901.

The ejection guide pillar 1103 penetrates the lower stamping die seat 1102 and is slidably connected to the inner surface of the lower die base 1101. Multiple groups of third sensors 1106 are provided on the left and right sides of the lower die base 1101. The lower ends of the third sensors 1106 are fixedly connected to the upper surface of the bottom plate 901, and the third sensors 1106 are electrically connected to the automatic control machine 2.

[0056] Specifically, first, through the cooperation of the internal components of the feeding mechanism 4, the metal sheet is placed on the upper surface of the lower stamping die base 1102 and the inside of the ejection template 1105, and then the automatic control machine 2 controls the electromagnetic absorber 703 to release the metal sheet, and retracts the electric push rod 701 to the second connecting block 702 to wait for the stamping to end. At the same time, the third sensor 1106 is used to check whether the metal sheet is placed correctly. If the detection is correct, the automatic control machine 2 starts the hydraulic rod 904 to press down the upper stamping die base 1002 and cooperate with the lower stamping die base 1102 to stamp the metal sheet, and the metal sheet is processed into a metal shell stamping part. If the third sensor 1106 detects that the placement is incorrect, the automatic control machine 2 will pause the equipment and issue an alarm to notify the processing personnel. After the stamping is completed, the hydraulic rod 904 will drive the upper stamping die base 1002 to rise, and at the same time, 1005 will move upward along the ejection guide column 1103 under the push of the auxiliary spring 1004, and the metal shell stamping parts after stamping will be ejected from the lower stamping die base 1102. Then the automatic control machine 2 controls the feeding assembly 7 to push the second connecting block 702 and the electromagnetic absorber 703 to absorb and remove the metal shell stamping parts, and send the metal shell stamping parts to the discharge conveyor 303 and then to the delivery device.

[0057] Refer to the attached Figure 8 With attached Fig. 9The pushing assembly 13 includes a connecting push rod 1301 and a T-shaped slider 1302. The upper ends of the connecting push rods 1301 are hinged to the left and right sides of the upper mold base 1001, and the lower ends of the connecting push rods 1301 are hinged to the upper side of the T-shaped slider 1302. The lower surface of the T-shaped slider 1302 is slidably connected with a support plate 1305. The front and rear sides of the support plate 1305 are fixedly connected with side guide plates 1303. The upper adjacent sides of the side guide plates 1303 are preset with guide grooves 1304. The inner surface of the slide groove 1304 is slidably connected to the outer surfaces of the front and rear sides of the T-shaped slider 1302, the upper surface of the far end of the support plate 1305 is fixedly connected with the fixing plate 1306, the adjacent sides of the support plate 1305 are fixedly connected with the limiting plate 1307, the lower surface of the side guide plate 1303 is fixedly connected with the mounting block 1308, the lower surface of the mounting block 1308 is fixedly connected to the upper surface of the work table 1, and the inner surface of the T-shaped slider 1302 is fixedly connected to the injection assembly 14.

[0058] Specifically, when the hydraulic rod 904 pushes the lower mold base 1101 downward, the connecting push rod 1301 hinged on both sides of the lower mold base 1101 can push the T-shaped slider 1302 to slide along the guide groove 1304 on the side guide plate 1303. While moving, the fixed plate 1306 squeezes the injection assembly 14 installed on the T-shaped slider 1302 as a power to spray lubricating oil mist to lubricate the metal sheet. The mounting block 1308 can fix the T-shaped slider 1302 on the upper surface of the work table 1, and the limit plate 1307 can limit the T-shaped slider 1302.

[0059] The fuel injection assembly 14 includes a pressure push rod 1401 and a fuel injection cylinder 1402. The distal ends of the pressure push rod 1401 are fixedly connected to the adjacent sides of the fixed plate 1306. The outer surfaces of the pressure push rod 1401 are slidably connected to the inner surfaces of the fuel injection cylinder 1402. The outer surfaces of the fuel injection cylinder 1402 are fixedly connected to the inner surfaces of the T-shaped slider 1302. The outer surfaces of the pressure push rod 1401 are provided with return springs 1403. The upper sides of the fuel injection cylinders 1402 are fixedly connected to the fuel delivery pipes 1404. The adjacent sides of the fuel injection cylinders 1402 are fixedly connected to the nozzles 1405. The adjacent sides of the nozzles 1405 are fixedly connected to the atomizing nozzles 1406.

[0060] Specifically, when the connecting push rod 1301 pushes the T-shaped slide block 1302 to move to both sides, the T-shaped slide block 1302 drives the fuel injection cylinder 1402 fixed inside to move to both sides, pushing the fuel injection cylinder 1402 to overcome the elastic force of the return spring 1403 and move along the pressure push rod 1401. Since the far sides of the pressure push rod 1401 are fixed on the adjacent sides of the fixed plate 1306, the pressure push rod 1401 will form a contact with the fuel injection cylinder 1402 as the fuel injection cylinder 1402 moves. 2. As the pressure inside the oil spray barrel 1402 increases, the lubricating oil inside the oil spray barrel 1402 will flow along the nozzle 1405 to the atomizing nozzle 1406, and after reaching the pressure threshold, it will be atomized and sprayed out through the atomizing nozzle 1406. The sprayed lubricating oil mist forms a low friction layer on the surface of the metal sheet to reduce the friction generated when the upper stamping die base 1002 and the lower stamping die base 1102 stamp the metal sheet, thereby improving the surface quality of the metal shell stamping parts.

[0061] In addition, refer to the attached Figure 1-10 The present invention provides a method for a metal shell stamping part processing system, comprising the following steps:

[0062] Step 1: Pre-clean and polish the cut metal sheets of appropriate size;

[0063] Step 2: The pre-treated metal sheets are sequentially fed into the feed conveyor belt 301 via the conveyor belt, and the equipment is started by the automatic control machine 2;

[0064] Step 3: When the metal sheet is fed into the feeding conveyor belt 301 and reaches the leftmost side, the first sensor 302 senses the presence of the metal sheet, and starts the rotating assembly 5 on the feeding mechanism 4 through the automatic control machine 2 to rotate rightward to the upper part of the feeding conveyor belt 301, and then controls the rotating assembly 5 to cooperate with the lifting assembly 6 to move the electromagnetic absorber 703 to the top of the metal sheet, and then when the sensing probe 704 senses the metal sheet, the sensing probe 704 is started to absorb the metal sheet, and then the rotating assembly 5, the lifting assembly 6, and the feeding assembly 7 are controlled by the automatic control machine 2 to cooperate to feed the metal sheet into the lower stamping die base 1102;

[0065] Step 4: After the metal sheet is moved to the upper side of the lower stamping die base 1102 by the cooperation of the rotating component 5, the lifting component 6, and the feeding component 7, the lifting component 6 controls the electromagnetic absorber 703 to move downward to place the metal sheet on the upper surface of the lower stamping die base 1102 and the inside of the ejection template 1105, and then the automatic control machine 2 controls the electromagnetic absorber 703 to close and put the metal sheet down, and then controls the electric push rod 701 on the feeding component 7 to drive the second connecting block 702 to retract, and uses the third sensor 1106 to check whether the metal sheet is placed correctly. If the detection is correct, the automatic control machine 2 starts the pressure component 9 to press the upper die component 10 to stamp the metal sheet. If it is not correct, the automatic control machine 2 will pause the equipment and issue an alarm to notify the processing personnel;

[0066] Step 5: While the pressure component 9 pushes the upper die component 10 downward, the upper die base 1001 drives the push components 13 on both sides to move to both sides, and pushes the oil spray component 14 to move. While the oil spray component 14 moves to both sides, it sprays lubricating oil mist to lubricate the upper surface of the metal sheet to reduce the friction between the lower die component 11 and the upper die component 10 during the stamping process. If it is necessary to lubricate the lower stamping die base 1102 and the ejection template 1105 on the lower die component 11, the automatic control machine 2 controls the pressure component 9 to push the lower die component 11 to perform air compression once, so that the lower stamping die base 1102 and the ejection template 1105 can be lubricated through the lubrication mechanism 12;

[0067] Step 6: After completing the stamping of the metal sheet, the pressure component 9 drives the lower die component 11 to lift up and reset, and at the same time drives the lubrication mechanism 12 to reset. Then, the lower die component 11, under the cooperation of the ejection spring 1104 and the ejection template 1105, pushes the processed metal shell stamping part out of the lower stamping die seat 1102 along the ejection guide column 1103. Then, the automatic control machine 2 controls the lifting component 6 and the feeding component 7 to move the electromagnetic absorber 703 to the upper end of the lower stamping die seat 1102 and move it downward, and the induction probe When 704 senses the metal shell stamping part, the electromagnetic absorber 703 is started to absorb the metal shell, and the metal shell stamping part is moved to the left to the upper side of the discharge conveyor belt 303 through the automatic control machine 2. After the second sensor 304 senses the metal shell, the automatic control machine 2 turns off the electromagnetic absorber 703 and places the metal shell stamping part on the discharge conveyor belt 303, and the discharge conveyor belt 303 sends it out of the equipment. Then the automatic control machine 2 controls the feeding mechanism 4 to reset and prepare for the next stamping process cycle.
