Description

Technical Field

[0001] This invention belongs to the field of stamping forming, specifically a metal stamping part device that integrates continuous stamping forming and online quality inspection. Background Technology

[0002] Aluminum alloy sheet stamping into cup-shaped parts is one of the key processes in the field of metal plastic processing. With its technical advantages of high forming precision, high production efficiency and low manufacturing cost, it is widely used in many fields such as food packaging containers and daily heat preservation appliances. Cup-shaped stamping parts have become the core basic components for achieving standardized and efficient manufacturing in various industries due to their regular and uniform structure, excellent mechanical load-bearing performance and suitability for large-scale mass production.

[0003] In the existing metal stamping forming equipment operation process, the blank is accurately transported to the designated working position of the equipment through an automated feeding mechanism or manual operation to ensure that the positioning reference of the blank and the upper and lower dies are completely matched. After the equipment is started, the drive mechanism drives the upper die to move downward and gradually achieve the mold closing action with the lower die. During the mold closing process, the die applies a preset forming pressure to the blank, causing the blank to undergo plastic deformation along the mold cavity contour, thereby completing the corresponding stamping process.

[0004] After the existing equipment completes the stamping process, it only performs a simple demolding action. The wall thickness deviation of the workpiece needs to be re-inspected by humans or testing equipment after demolding. This not only increases the process flow time and labor costs, but also makes it impossible to provide real-time feedback of defect data to adjust subsequent stamping parameters, which makes it easy for batch quality problems to occur in the same batch of workpieces.

[0005] Therefore, the present invention provides a metal stamping part device that integrates continuous stamping forming and online quality inspection. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A continuous stamping forming and online quality inspection integrated metal stamping device, comprising a machine body, a first mold, a second mold, and a third mold. The first mold and the second mold are slidably mounted on the machine body. The third mold is adapted to the inner wall contour of a cup-shaped hollow workpiece. The third mold includes: a first cylindrical block and a second cylindrical block; a pneumatic detection and demolding integrated component, comprising: a support rod rotatably mounted inside the first cylindrical block, with the second cylindrical block slidably connected to it; a first air passage channel opened on the second cylindrical block and the support rod; a nozzle slidably mounted on the second cylindrical block, communicating with the first air passage channel; and a sensor mounted on the second cylindrical block. A measurement space is formed between the stamped workpiece and the third mold. The nozzle supplies detection gas into this measurement space. The sensor determines the workpiece wall thickness by detecting changes in gas parameters within the first air passage channel. Simultaneously, the airflow forms an air film between the workpiece and the third mold.

[0008] Preferably, the first gas passage is externally connected to a gas supply system, which is used to supply a constant flow of detection gas. The sensor is a pressure sensor, which determines the change in workpiece wall thickness by detecting the gas pressure fluctuation amplitude in the first gas passage.

[0009] Preferably, the first gas passage is connected to an external gas supply system, which is used to supply constant pressure detection gas. The sensor is a flow sensor, which determines the change in workpiece wall thickness by detecting the flow fluctuation amplitude in the first gas passage.

[0010] Preferably, the nozzles comprise a plurality of nozzles, which are arranged in a ring array on the second cylindrical block; this increases the detection speed, accelerates the demolding process, and adapts to the high-speed operation requirements of continuous stamping production lines.

[0011] Preferably, the integrated pneumatic detection and demolding assembly further includes: a circular plate rotatably mounted on the second cylindrical block; a slider mounted on the nozzle; and a groove formed on the circular plate, in which the slider slides.

[0012] Preferably, the integrated pneumatic detection and demolding assembly further includes: a threaded rod fixedly mounted on the support rod; and a threaded sleeve fixedly mounted on the circular plate. When the circular plate drives the threaded sleeve to rise and fall along the axis of the support rod, the circular plate, together with the threaded sleeve, is driven to rotate synchronously around the axis of the support rod through the threaded transmission between the threaded sleeve and the threaded rod.

[0013] Preferably, the mold further includes: a plurality of grippers rotatably mounted on the second mold for gripping workpieces; a slide plate slidably mounted on the second mold; a pull rope for driving the grippers to rotate, one end of the pull rope being wound around the grippers and the other end of the pull rope being fixedly mounted on the slide plate; and an electromagnet for driving the slide plate to slide, the electromagnet being fixedly mounted on the second mold.

[0014] Preferably, the device further includes: a telescopic rod fixedly mounted on the support rod; a round rod mounted on the second mold, the round rod being slidably mounted on the machine body; a transmission assembly mounted on the round rod; and a driving component that drives the second mold to move via the transmission assembly and the round rod; wherein the transmission assembly includes a first disc and a second disc, the first disc being fixedly connected to the round rod, the second disc being fixedly connected to the end of the driving component, a planetary gear transmission mechanism connecting the first disc and the second disc, a first ring being fixedly mounted on the internal gear ring of the planetary gear transmission mechanism, a second ring being fixedly mounted on the machine body, the first ring and the second ring being threadedly driven, the end of the telescopic rod rotating unidirectionally with the sun gear of the planetary gear transmission mechanism, the end of the telescopic rod being rotatably connected to the first disc, and the sun gear of the planetary gear transmission mechanism being rotatably connected to the first disc and the second disc.

[0015] Preferably, the integrated pneumatic detection and demolding assembly further includes a second air passage channel on the support rod, the second air passage channel being used to transport gas, allowing the second cylindrical block to slide relative to the support rod. A slip ring is rotatably mounted on the support rod and the slip ring is fixedly connected to the machine body. The slip ring has a first chamber and a second chamber, the first chamber communicating with the second air passage channel and the second chamber communicating with the first air passage channel. A three-way valve communicating with the first chamber and the second chamber is provided on the slip ring.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses an integrated metal stamping device for continuous stamping and online quality inspection, which integrates the metal stamping process and the online workpiece wall thickness inspection process into the same device. It eliminates the need to transfer the stamped workpiece to a dedicated inspection device for offline inspection. The inspection process is synchronized with the demolding action, which is suitable for the high-speed operation requirements of continuous stamping production lines. It significantly shortens the production cycle of a single workpiece, improves the overall operating efficiency of the production line, and can provide real-time feedback of defect data to adjust subsequent stamping parameters, thus ensuring quality.

[0017] 2. The integrated metal stamping device for continuous stamping and online quality inspection described in this invention uses two modes: constant flow air pressure detection or constant pressure flow detection. Based on the influence of gap changes on gas flow resistance, the device uses sensors to capture fluctuations in air path parameters to determine the workpiece wall thickness deviation. The continuously supplied airflow during the detection process can form an air film between the workpiece and the contact surface of the third mold, reducing the friction between the mold and the workpiece and improving the yield of finished products.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-8As shown in the figure, an integrated metal stamping device for continuous stamping and online quality inspection according to an embodiment of the present invention includes a machine body 1, a first mold 2, a second mold 3, and a third mold 4. The first mold 2 and the second mold 3 are both slidably mounted on the machine body 1 and cooperate with the third mold 4 to complete the stamping. The third mold 4 is adapted to the inner wall contour of the cup-shaped hollow workpiece. The third mold 4 includes: a first columnar block 41 and a second columnar block 42 mounted on the machine body 1 for forming the inner wall shape of the workpiece. The first columnar block 41 is fixedly connected to the machine body 1; and a pneumatic inspection and demolding integrated component 43, which includes: a component rotatably mounted inside the first columnar block 41. The support rod 431 is slidably connected to the second cylindrical block 42; a first air passage 432 is opened on the second cylindrical block 42 and the support rod 431; a nozzle 433 is slidably installed on the second cylindrical block 42 and is connected to the first air passage 432; a sensor 434 is installed on the second cylindrical block 42; wherein, a measuring space is formed between the stamped workpiece and the third mold 4, the nozzle 433 supplies detection gas into the measuring space, and the sensor 434 determines the workpiece wall thickness by detecting the change of gas parameters in the first air passage 432. At the same time, the airflow forms an air film between the workpiece and the third mold 4 to achieve assisted demolding.

[0022] The No. 1 gas passage 432 is connected to an external gas supply system, which is used to supply a constant flow of detection gas. The sensor 434 is a pressure sensor, which determines the change in workpiece wall thickness by detecting the gas pressure fluctuation amplitude in the No. 1 gas passage 432.

[0023] The No. 1 gas passage 432 is connected to an external gas supply system, which is used to supply constant pressure detection gas. The sensor 434 is a flow sensor, which determines the change in workpiece wall thickness by detecting the fluctuation of flow rate in the No. 1 gas passage 432.

[0024] Specifically, the workpiece is placed on the second mold 3 and the third mold 4 through an automated feeding mechanism or manual operation (initially, the upper surfaces of the third mold 4 and the second mold 3 are at the same height). Then, the first mold 2 is controlled to move downward until it fits against the second mold 3 to press the edge of the workpiece. Then, the second mold 3 and the first mold 2 are controlled to move downward together, causing the workpiece to undergo plastic deformation along the contour of the third mold 4, thereby completing the corresponding stamping process. After the stamping operation is completed, a measurement space is formed between the workpiece and the third mold 4. This space provides the necessary detection environment for gas detection. During demolding, the first mold 2 is first controlled to move upward to its initial position, and then the second cylindrical block 42 is controlled to move upward, exposing the nozzle 433 and stopping. Simultaneously, the second mold 3 is controlled to move upward synchronously and continuously to complete the initial demolding action. Then, the nozzle 433 is controlled to slide relative to the second cylindrical block 42, bringing the nozzle 433 closer to the inner wall of the workpiece and reducing the gap between them. Subsequently, the nozzle 433 stably supplies detection gas into the measurement space. At the same time, the support rod 431 is controlled to rotate, causing the nozzle 433 to rotate synchronously, so that the gas is evenly sprayed into the measurement space. If there is a deviation in the workpiece wall thickness, it will affect the measurement space. Changes in the gap size affect the gas flow resistance, causing corresponding fluctuations in the gas parameters within the first gas passage 432. The sensor 434 captures these parameter changes in real time and transmits the signal to the control system. The control system accurately determines whether the workpiece wall thickness meets the standard by using a preset parameter threshold and deviation calculation model (details of the control system model algorithm are not described in detail here). Meanwhile, the continuously supplied airflow forms an air film between the workpiece and the third mold 4. This air film reduces the friction between the workpiece and the mold, assisting in demolding and reducing the probability of scratches or deformations on the workpiece surface caused by traditional mechanical demolding methods. The demolding and inspection of the workpiece are completed when the second mold 3 returns to its initial height. Constant flow detection mode: When the workpiece wall thickness is too thick, the measurement space gap becomes smaller, the gas flow resistance increases, and the gas pressure in the gas path rises. When the workpiece wall thickness is too thin, the gap becomes larger, the flow resistance decreases, and the gas pressure in the gas path decreases. The pressure sensor captures this fluctuation and feeds it back to the control system to realize wall thickness detection. Constant pressure detection mode: When the workpiece wall thickness is too thick, the measurement space gap becomes smaller, the gas flow resistance increases, and the gas flow rate in the gas path will decrease. When the workpiece wall thickness is too thin, the gap becomes larger, the gas resistance decreases, and the flow rate will increase. The flow sensor captures this fluctuation signal and transmits it to the control system to realize wall thickness detection.

[0025] like Figure 5 As shown, there are several nozzles 433, and they are arranged in a ring array on the second columnar block 42; this improves the detection speed, speeds up the demolding process, and adapts to the high-speed operation requirements of continuous stamping production lines.

[0026] like Figures 5-7 As shown, the pneumatic detection and demolding integrated component 43 also includes: a circular plate 435 rotatably mounted on the second columnar block 42; a slider 436 mounted on the nozzle 433; and a groove 437 formed on the circular plate 435, in which the slider 436 slides.

[0027] The integrated pneumatic detection and demolding assembly 43 also includes: a threaded rod 438 fixedly mounted on the support rod 431; and a threaded sleeve 439 fixedly mounted on the circular plate 435. When the circular plate 435 drives the threaded sleeve 439 to rise and fall along the axis of the support rod 431, the circular plate 435 and the threaded sleeve 439 are driven to rotate synchronously around the axis of the support rod 431 through the threaded transmission between the threaded sleeve 439 and the threaded rod 438.

[0028] Specifically, when the second cylindrical block 42 moves upward relative to the first cylindrical block 41, it drives the circular plate 435 and the threaded sleeve 439 to move upward synchronously. Through the threaded transmission between the threaded sleeve 439 and the threaded rod 438, the circular plate 435 rotates. Since the slider 436 slides in the groove 437 of the circular plate 435, based on the guiding effect of the groove 437, after the circular plate 435 rotates, the slider 436 drives the nozzle 433 to move closer to the inner wall of the workpiece, reducing the gap between the two and providing spacing conditions for subsequent pneumatic inspection operations.

[0029] like Figure 5 As shown, it also includes: several grippers 5 rotatably mounted on the second mold 3, the grippers 5 being used to clamp workpieces; a slide plate 6 slidably mounted on the second mold 3; a pull rope 7 for driving the grippers 5 to rotate, one end of the pull rope 7 being wound around the grippers 5, and the other end of the pull rope 7 being fixedly mounted on the slide plate 6; and an electromagnet 8 for driving the slide plate 6 to slide, the electromagnet 8 being fixedly mounted on the second mold 3.

[0030] Specifically, a torsion spring for resetting is provided between the gripper 5 and the second mold 3. During the demolding process of the first mold 2 moving upward, the electromagnet 8 is activated simultaneously to drive the slide plate 6 to slide downward, thereby pulling the pull rope 7 to rotate the gripper 5, so that the end of the gripper 5 presses against the upper part of the workpiece corner, thereby achieving the limiting and fixing of the workpiece (the clamping force applied by the gripper 5 does not need to be too large, only to limit the rotation of the workpiece), preventing the workpiece from rotating and shifting during the demolding process.

[0031] like Figure 2 , Figure 3 and Figure 8As shown, it also includes: a telescopic rod 9 fixedly mounted on the support rod 431; a round rod 10 mounted on the second mold 3, the round rod 10 being slidably mounted on the machine body 1; a transmission assembly 11 mounted on the round rod 10; and a driving component 12 that drives the second mold 3 to move via the transmission assembly 11 and the round rod 10; wherein, the transmission assembly 11 includes a first disc 111 and a second disc 112, the first disc 111 being fixedly connected to the round rod 10, the second disc 112 being fixedly connected to the end of the driving component 12, and the first disc 111... A planetary gear transmission mechanism 113 is connected between the first and second disks 112. A first ring 114 is fixedly installed on the internal gear ring of the planetary gear transmission mechanism 113, and a second ring 115 is fixedly installed on the body 1. The first ring 114 and the second ring 115 are threadedly driven. The end of the telescopic rod 9 rotates unidirectionally with the sun gear of the planetary gear transmission mechanism 113. The end of the telescopic rod 9 is rotatably connected to the first disk 111. The sun gear of the planetary gear transmission mechanism 113 is rotatably connected to the first disk 111 and the second disk 112.

[0032] Specifically, the drive component 12 can be a conventional drive element such as a cylinder or hydraulic cylinder. The movement drive of the first mold 2 also adopts the same adaptation method as described above. The sun gear only drives the telescopic rod 9 to rotate synchronously during the upward movement of the second mold 3. During the upward movement of the drive component 12, the second disc 112, the transmission component 11, the first disc 111, the round rod 10, and the second mold 3, the first ring 114 moves upward synchronously. Since the first ring 114 and the second ring 115 are threadedly driven, the first ring 114 rotates and drives the internal gear ring of the planetary gear transmission mechanism 113 to rotate synchronously. Through the transmission of the planetary gears mounted on the first disc 111 and the second disc 112, the sun gear is driven to rotate. The sun gear drives the telescopic rod 9 to rotate synchronously, thereby driving the support rod 431, the second cylindrical block, and the nozzle 433 to rotate synchronously.

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, the pneumatic detection and demolding integrated component 43 also includes a second air passage 4310 opened on the support rod 431. The second air passage 4310 is used to transmit gas, so that the second cylindrical block 42 slides relative to the support rod 431. A slip ring 4311 is rotatably installed on the support rod 431. The slip ring 4311 is fixedly connected to the body 1. A first chamber 4312 and a second chamber 4313 are opened on the slip ring 4311. The first chamber 4312 is connected to the second air passage 4310, and the second chamber 4313 is connected to the first air passage 432. A three-way valve 4314 is provided on the slip ring 4311, which is connected to the first chamber 4312 and the second chamber 4313.

[0034] Specifically, the three-way valve 4314 is electrically controlled and connected to an external air supply system. The first chamber 4312 is also connected to an external air intake system. During operation, the three-way valve 4314 is first connected to the first chamber 4312 of the slip ring 4311. The gas is input into the gap between the second cylindrical block 42 and the support rod 431 through the second air passage 4310. The second cylindrical block 42 is lifted upward under pressure. After the processing is completed, the air intake system is switched to operate, so that the second cylindrical block 42 is reset under the action of air pressure difference.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
