Description

Technical Field

[0001] The invention relates to the technical field of shaping dies, and in particular to a metal part hot pressing shaping device with an optical module positioning function. Background Art

[0002] The hot pressing shaping device is a professional device specially used to optimize the appearance of metal parts and improve their surface flatness. When shaping metal parts, the device rearranges and refines the grain structure inside the metal through heating treatment, thereby effectively eliminating internal residual stress; then, with the help of a specially designed mold, pressure is applied to the metal part to ensure that the surface of the part achieves the ideal flatness effect and successfully completes the shaping and correction process.

[0003] However, in practical applications, especially for hot pressing and shaping operations of sheet metal, current hot pressing and shaping devices often rely on suction cups to grab and transport metal sheets to the preset mold position. Since the temperature of the mold is high when it is working, the suction cup is exposed to high temperature for a long time. This environmental factor causes the suction cup material to gradually age and harden, weakening the sealing performance between it and the metal parts. As the sealing performance decreases, the suction cup's adsorption force on the metal parts weakens, and even desorption may occur, increasing the risk of displacement of metal parts during transportation, which not only affects the accuracy of part placement, but also causes problems such as mold damage or substandard finished product quality.

A positioning module is arranged on the frame 1. The positioning module is composed of an electric push rod and a baffle. The baffle is used to limit the position of the edge of the metal part. The metal part is pushed to move by the telescopic end of the electric push rod so that the edge of the metal part fits with the adjacent baffle, thereby adjusting the position of the metal part and reducing the deviation between the metal part and the mold; the linear slide group 5 is an existing device, and the specific structure will not be described in detail. The linear slide group 5 is used to drive the fixed plate 6 to move up and down and forward and backward. Initially, the fixed plate 6 and the parts thereon are located Between the upper mold 3 and the lower mold 4, the position of the fixed plate 6 shown in the figure is aligned with the metal part. The optical module is an existing device for detecting whether the linear slide group 5 drives the fixed plate 6 to a specified distance. The specific structure will not be described in detail. In this embodiment, the telescopic end of the first elastic telescopic rod 7 does not move, and the first elastic telescopic rod 7 can be regarded as a straight rod. In this embodiment, the connecting ring 8 and the air pipe 9 can be regarded as a fixed connection. The air pipe 9 is externally connected to an air pump. The air pump generates negative pressure by extracting gas from the air pipe 9 to fix the metal part with the suction cup 10. The suction cup 10 is made of high temperature resistant rubber material. When the suction cup 10 is squeezed and contacted with the metal part, the suction cup 10 is deformed and the contact area between it and the metal part is increased. Initially, the telescopic end of the second elastic telescopic rod 12 is in an extended state, and the torsion spring 13 is in a stored force state. The torsion spring 13 is used to drive the second elastic telescopic rod 12 to rotate 90°. Initially, the telescopic end of the second elastic telescopic rod 12 is in an extended state, and the support plate 14 is located below the suction cup 10. The support plate 14 is used to support the parts from the bottom to complete the fixation. The limiting mechanism is used to limit the initial angle of the second elastic telescopic rod 12.

[0021] Further, such as Figure 6-Figure 8 As shown, the limiting mechanism includes: a third elastic telescopic rod 15, which is fixed to the trachea 9, the telescopic end of the third elastic telescopic rod 15 is fixed to the limiting rod 16, the telescopic part of the second elastic telescopic rod 12 is provided with a limiting groove, the limiting rod 16 slides in the limiting groove of the telescopic part of the second elastic telescopic rod 12, and the fixed part of the third elastic telescopic rod 15 is provided with an air inlet and an air outlet; an adjusting component is arranged on the third elastic telescopic rod 15, and the adjusting component is used to adjust the opening and closing of the air inlet on the fixed part of the third elastic telescopic rod 15; a power component is arranged on the trachea 9, and is used to drive the telescopic end of the third elastic telescopic rod 15 to move.

[0022] Further, such as Figure 8 As shown, the diameter of the air inlet hole on the fixing portion of the third elastic telescopic rod 15 is not less than the diameter of the air outlet hole thereon.

[0023] The above scheme provides a method for limiting the rotation of the second elastic telescopic rod 12; the end of the limiting rod 16 close to the second elastic telescopic rod 12 is a hemispherical head, which is used to facilitate the limiting rod 16 to enter the limiting groove of the second elastic telescopic rod 12, and the depth of the upper limiting groove on the second elastic telescopic rod 12 is greater than the radius of the hemispherical head on the limiting rod 16, which is used to ensure that the limiting rod 16 cannot separate from the limiting groove of the second elastic telescopic rod 12 by itself, and the diameter of the air inlet hole on the third elastic telescopic rod 15 is not less than the diameter of the air outlet hole thereon, ensuring that the telescopic end of the third elastic telescopic rod 15 does not move when the air inlet hole is not sealed.

[0024] Further, such as Figure 6-Figure 8 As shown, the adjustment component includes: a sealing frame 19, which is slidably connected to the fixed part of the third elastic telescopic rod 15, and the sealing frame 19 is used to seal the air inlet hole on the fixed part of the third elastic telescopic rod 15. The sealing frame 19 is fixedly connected to an adjustment block 1901, and an inclined surface is arranged on the lower side of the adjustment block 1901. A tension spring 20 is arranged between the sealing frame 19 and the air pipe 9.

[0025] Further, such as Figure 4-Figure 7 As shown, the adjustment component also includes: an adjustment ring 17, which is fixed to the suction cup 10 and contacts the air pipe 9; a trapezoidal block 18, which is fixed to the adjustment ring 17 and is used to push the adjustment block 1901 to move.

[0026] The above scheme provides a method for sealing the air inlet hole of the third elastic telescopic rod 15 after the suction cup 10 contacts the metal part; the sealing frame 19 is composed of a full ring and a half ring, wherein the half ring of the sealing frame 19 is used to seal the air inlet hole on the third elastic telescopic rod 15, and the length of the half ring is greater than the diameter of the air inlet hole on the third elastic telescopic rod 15, and the tension spring 20 is used to drive the sealing frame 19 to reset; the cross-section of the trapezoidal block 18 is a right-angled trapezoid, and the inclined surface of the trapezoidal block 18 is used to squeeze the inclined surface of the adjusting block 1901, so that the adjusting block 1901 drives the sealing frame 19 to move.

[0027] Further, such as Figure 5-Figure 7 As shown, the power assembly includes: a fourth elastic telescopic rod 21, which is fixed to the trachea 9, and the fixed part of the fourth elastic telescopic rod 21 is connected to the trachea 9; an arc frame 22, which is fixed to the telescopic end of the fourth elastic telescopic rod 21, and the arc frame 22 is slidably connected to the fixed part of the third elastic telescopic rod 15, and the arc frame 22 is fixed with a connecting pipe for connecting the third elastic telescopic rod 15 and the trachea 9.

[0028] Further, such as Figure 6-Figure 8As shown, it also includes: piston plates 901, the number of which is the same as the number of tracheas 9, which are slidably connected to adjacent tracheas 9, a first spring 902 is fixedly connected between the piston plate 901 and the trachea 9, the piston plate 901 divides the trachea 9 into two upper and lower chambers, the third elastic telescopic rod 15 is connected to the upper chamber of the trachea 9, and the fourth elastic telescopic rod 21 is connected to the lower chamber of the trachea 9.

[0029] The above scheme provides a method for extracting the gas in the third elastic telescopic rod 15 after the fixing force of the suction cup 10 on the metal part is reduced; initially, the telescopic end of the fourth elastic telescopic rod 21 is in an extended state; an annular protrusion is provided in the air pipe 9 to limit the position of the piston plate 901, so that the piston plate 901 cannot move to the connection between the air pipe 9 and the connecting pipe thereon, and the first spring 902 is used to push the piston plate 901 to reset, and the rate at which the gas in the third elastic telescopic rod 15 enters the air pipe 9 is much lower than the rate at which the air pump extracts the gas in the air pipe 9, so that the normal movement of the piston plate 901 is not affected.

[0030] Further, such as Figure 3 As shown, the frame body 1 is fixed with the same number of reset blocks 141 as the support plates 14 . The reset blocks 141 are provided with inclined surfaces. The reset blocks 141 are used to squeeze the adjacent support plates 14 and make them rotate.

[0031] The above scheme provides a method for driving the support plate 14 to reset during the process of placing the metal part into the lower mold 4; there are four reset blocks 141 on the frame 1, and taking the direction of the inclined surface on the reset block 141 on the right rear side as an example, the inclined surface on the reset block 141 faces the right front, and when the metal part is placed into the lower mold 4, the inclined surface of the reset block 141 squeezes the support plate 14, causing the support plate 14 to rotate and move out from the bottom side of the metal part.

[0032] Workflow: When the metal parts need to be hot-pressed and trimmed, the staff will place the metal parts between the electric push rod and the baffle in sequence through the existing loading device. Then the staff will start the electric push rod, and the telescopic end of the electric push rod will extend and push the metal parts to the right until the right side of the metal part contacts the baffle. The telescopic end of the electric push rod stops moving and completes the preliminary calibration of the metal part. Then the staff will start the two linear slide groups 5, and the linear slide groups 5 will drive the parts thereon to move forward.

[0033] The following takes the moving direction of the right linear slide group 5 and the parts thereon as an example. In the process of the linear slide group 5 moving forward, the linear slide group 5 drives the two first elastic telescopic rods 7 to move forward through the fixed plate 6, and the telescopic end of the first elastic telescopic rod 7 drives the adjacent air pipe 9 and the parts thereon to move forward through the connecting ring 8. When the linear slide group 5 moves to the specified position, it stops moving forward. At this time, the center line of the fixed plate 6 and the center line of the metal part are located on the same vertical plane. The linear slide group 5 drives the first elastic telescopic rod 7 and the parts thereon to move downward through the fixed plate 6. As the first elastic telescopic rod 7 moves downward, the first elastic telescopic rod 7 drives the air pipe 9 to move downward through the connecting ring 8, and the air pipe 9 drives the suction cup 10 and the connecting frame 11 to move downward. The connecting frame 11 drives the support plate 14 to move downward through the second elastic telescopic rod 12. When the lower side of the support plate 14 contacts the frame body 1, the support plate 14 stops moving, and the fixed part of the second elastic telescopic rod 12 continues to move and its telescopic end is gradually retracted (in this process, the limit rod 16 is always located in the limit groove of the telescopic part of the second elastic telescopic rod 12).

[0034] During the process of gradually retracting the telescopic end of the second elastic telescopic rod 12, when the suction cup 10 contacts the metal part, the two squeeze each other, causing the suction cup 10 to gradually deform and fit the adjacent area of ​​the metal part. At this time, the air pump starts and extracts the gas in the upper chamber of the air pipe 9, causing the piston plate 901 to move upward and compress the first spring 902. The air pressure in the lower chamber of the air pipe 9 decreases, generating an upward force on the metal part until the suction cup 10 can no longer be deformed, the air pipe 9 stops moving, and the linear slide group 5 stops driving the fixed plate 6 to move downward.

[0035] During the process of the air pump extracting gas from the trachea 9, as the piston plate 901 moves upward, the air pressure in the lower chamber of the trachea 9 and the fourth elastic telescopic rod 21 decreases, the telescopic end of the fourth elastic telescopic rod 21 is retracted and drives the arc frame 22 to move toward the axial direction of the trachea 9, so that the third elastic telescopic rod 15 is no longer connected to the trachea 9.

[0036] During the deformation of the suction cup 10, the air pipe 9 drives the third elastic telescopic rod 15 and the fourth elastic telescopic rod 21 to move downward, the third elastic telescopic rod 15 drives the adjusting block 1901 to move synchronously through the sealing frame 19, and the fourth elastic telescopic rod 21 and the arc frame 22 move downward synchronously. When the adjusting block 1901 contacts the trapezoidal block 18, the trapezoidal block 18 squeezes the adjusting block 1901, so that the adjusting block 1901 drives the sealing frame 19 to move and stretch the tension spring 20. After the air pipe 9 stops moving, the sealing frame 19 stops moving and seals the air inlet hole of the third elastic telescopic rod 15.

[0037] As the air pump continues to extract the gas in the air pipe 9, the piston plate 901 continues to move upward and compress the first spring 902. When the piston plate 901 contacts the annular protrusion in the air pipe 9, the piston plate 901 stops moving, and the air pressure in the lower chamber of the air pipe 9 stops changing. The air pump stops extracting the gas in the upper chamber of the air pipe 9 and keeps the internal air pressure unchanged. The suction cup 10 completes the fixation of the metal part, and the linear slide group 5 drives the fixed plate 6 and the parts thereon to move upward. The suction cup 10 drives the metal parts to move synchronously, and the telescopic end of the second elastic telescopic rod 12 extends and resets. When the fixed plate 6 moves to the specified height, the linear slide group 5 drives the fixed plate 6 to move backward and reset, so that the metal plate moves to the top of the upper mold 3. Then the linear slide group 5 drives the parts on it to move downward through the fixed plate 6. When the metal plate contacts the upper mold 3, the air pump disconnects from the air pipe 9, so that the outer The boundary gas enters the upper chamber of the air pipe 9, and the first spring 902 pushes the piston plate 901 to move downward and reset, so that the suction cup 10 releases the fixation of the metal plate and resets, and then the linear slide group 5 moves upward and forward again to move out from between the upper mold 3 and the lower mold 4, and the frame 1 starts the induction heater inside it to heat the upper mold 3 and the lower mold 4. At the same time, the telescopic end of the hydraulic push rod 2 drives the upper mold 3 to move downward and cooperate with the lower mold 4 to perform hot pressing and shaping on the metal parts. After the shaping is completed, the hydraulic push rod 2 drives the upper mold 3 to reset, and the linear slide group 5 repeats the above process of fixing the metal parts to re-fix the metal parts and take them out from the lower mold 4, and then moves the metal parts to the storage rack of the frame 1, and then repeats the above process to shape other metal parts. After the shaping of this batch of metal parts is completed, the linear slide group 5 drives the parts thereon to reset to the initial state.

[0038] In the process of the suction cup 10 driving the metal part to move upward, if the suction cup 10 is damaged and the sealing between it and the metal part is reduced, in the process of the suction cup 10 fixing the metal part, the outside air gradually enters the lower chamber inside the trachea 9, and the air pressure in the lower chamber inside the trachea 9 and the fourth elastic telescopic rod 21 gradually recovers, and the telescopic end of the fourth elastic telescopic rod 21 drives the arc frame 22 to reset, so that the third elastic telescopic rod 15 is connected to the trachea 9 (at this time, the sealing frame 19 seals the air inlet of the third elastic telescopic rod 15), the air pump extracts the gas from the third elastic telescopic rod 15, the telescopic end of the third elastic telescopic rod 15 extends out and drives the limiting rod 16 to move synchronously, so that the limiting rod 16 is separated from the limiting groove on the second elastic telescopic rod 12, and the torsion spring 13 drives the support plate 14 to rotate 90° clockwise (with the limiting groove on the second elastic telescopic rod 12) through the second elastic telescopic rod 12. Figure 5 The rotation direction of the middle support plate 14 is used as a reference (looking from top to bottom), so that the support plate 14 swings to the bottom of the metal part, supporting the metal part from below, so that the metal part is supported by sufficient force to prevent it from sliding or even falling off due to reduced fixing force during transportation, affecting the normal production of the metal part.

[0039] In the process of the linear slide group 5 driving the fixed plate 6 to move downward to place the metal plate into the lower mold 4, as the support plate 14 moves downward, after the support plate 14 contacts the reset block 141, the support plate 14 rotates in the opposite direction and resets under the extrusion of the reset block 141, and the support plate 14 drives the second elastic telescopic rod 12 to rotate synchronously and causes the torsion spring 13 to store force. When the air pump is turned off, the telescopic end of the third elastic telescopic rod 15 drives the limit rod 16 to reset, so that the limit rod 16 enters the limit groove of the second elastic telescopic rod 12 to complete the limit again. After the placement is completed, the staff replaces the damaged suction cup 10, and then repeats the above process to continue to shape the metal part.

[0040] Since the shape of existing metal parts is not flat, there are protrusions and depressions on the surface of the metal parts. After the metal casting is completed, the shrinkage deformation of the metal parts will change the positions of the protrusions and depressions on them, resulting in the protrusions and depressions on the metal parts being misaligned with the corresponding positions on the mold when the metal parts are placed, affecting the shaping effect of the metal parts and easily causing damage to the mold.

[0041] Further, such as Figure 3 , Figure 4 and Fig. 9 As shown, it also includes: a vibration component, the number of which is the same as the number of the air pipes 9, all of which are arranged on the frame 1, and are used to drive the air pipes 9 to shake, and the vibration component includes: a support frame 23, fixed to the frame 1, and the support frame 23 is fixed with a vibration plate 24; a transmission rod 25, fixed to the telescopic part of the first elastic telescopic rod 7, and the vibration plate 24 is provided with a wavy surface, and the wavy surface of the vibration plate 24 is used to push the telescopic end of the transmission rod 25 to move.

[0042] The above scheme provides a method for driving the metal part to shake when there is a protrusion on the surface of the metal part (hereinafter, the metal part is introduced as having only a protrusion), thereby further adjusting the position of the metal part to ensure that the position of the protrusion of the metal part is in contact with the corresponding position of the mold; in this embodiment, four vibration plates 24 are arranged on the support frame 23, and two vibration plates 24 form a group, and the two vibration plates 24 are respectively located on both sides of the axis of the adjacent first elastic telescopic rod 7, and the upper parts of the two vibration plates 24 in the same group are inclined outwardly, which is used to guide the transmission rod 25, so that the transmission rod 25 can enter between the two vibration plates 24 in the same group, so that the transmission rod 25 moves along the wave surface of the vibration plate 24. In this embodiment, the first elastic telescopic rod 7 has two symmetrically distributed transmission rods 25, so that the telescopic end of the first elastic telescopic rod 7 is evenly stressed.

[0043] Workflow: This section takes the moving direction of the linear slide group 5 on the right and the parts thereon as a reference. After the linear slide group 5 drives the fixed plate 6 to move backward to the specified position (at this time the metal part moves to the top of the lower mold 4), the linear slide group 5 drives the fixed plate 6 to move downward, and the fixed plate 6 drives the transmission rod 25 to move downward through the first elastic telescopic rod 7. As the transmission rod 25 moves downward, the transmission rod 25 gradually approaches the two adjacent vibration plates 24 until the metal part approaches the lower mold 4. The transmission rod 25 enters between the two adjacent vibration plates 24. The staff turns off the air pump to make the metal part fall into the lower mold 4. The transmission rod 25 moves downward along the wave surface of the vibration plate 24, so that the transmission rod 25 drives the expansion and contraction of the first elastic telescopic rod 7. The first elastic telescopic rod 7 drives the air pipe 9 to move synchronously through the connecting ring 8, so that the suction cup 10 squeezes the metal part through friction (in this process, the suction cup 10 has a downward squeezing force on the metal part), thereby driving the metal part to shake left and right, so that the protrusion on the metal part corresponds to the lower mold 4. When the protrusion on the metal part is aligned with the corresponding position on the lower mold 4, the metal part is stuck and no longer moves until the transmission rod 25 is separated from the wavy surface of the vibration plate 24. The linear slide group 5 stops driving the fixed plate 6 to move downward, the suction cup 10 stops shaking to complete the final adjustment of the position of the metal part, and the linear slide group 5 drives the parts on it to move in the opposite direction and reset. Then the hydraulic push rod 2 drives the upper mold 3 to move downward to shape the metal part.

[0044] Further, such as Figure 5 and Fig.10 As shown, it also includes: a fixed component, the number of which is the same as the number of the first elastic telescopic rods 7, which are respectively arranged on adjacent first elastic telescopic rods 7 and are used to limit the height of the trachea 9, and the fixed component includes: an extrusion block 26, which is fixedly connected to the telescopic part of the first elastic telescopic rod 7, the connecting ring 8 is slidably connected to the trachea 9, the extrusion block 26 is provided with an inclined surface, and a second spring 27 is fixedly connected between the connecting frame 11 and the connecting ring 8; a connecting plate 28, which is fixedly connected to the adjacent connecting frame 11, and the connecting plate 28 is slidably connected with an L-shaped plate 29, the L-shaped plate 29 is located on the moving path of the adjacent extrusion block 26, the support frame 23 is located on the moving path of the adjacent L-shaped plate 29, and a third spring 30 is fixedly connected between the L-shaped plate 29 and the connecting plate 28.

[0045] The above scheme provides a way to reduce the downward extrusion force on the metal parts when the metal plate is driven to shake; the inclined surface of the extrusion block 26 is used to extrude the L-shaped plate 29. In this embodiment, the connecting ring 8 and the air pipe 9 can slide relative to each other, and the second spring 27 is used to push the air pipe 9 downward relative to the connecting ring 8 through the connecting frame 11; the third spring 30 is always in a compressed state, which is used to maintain the stability of the position of the L-shaped plate 29.

[0046] Working process: in the above process of placing the metal part into the lower mold 4, as the first elastic telescopic rod 7 drives the air pipe 9 to move downward through the connecting ring 8, the first elastic telescopic rod 7 drives the extrusion block 26 to move downward, the air pipe 9 drives the connecting plate 28 to move downward through the connecting frame 11, and the connecting plate 28 drives the L-shaped plate 29 and the third spring 30 to move downward until the L-shaped plate 29 contacts the support frame 23, the L-shaped plate 29 stops moving downward (at this time, the transmission rod 25 is about to enter the wave area of ​​the vibration plate 24), the connecting plate 28 stops moving downward, the connecting frame 11 and the air pipe 9 stop moving downward, at this time the air pump is turned off, the metal part falls into the lower mold 4, and the downward extrusion force of the suction cup 10 on the metal part no longer increases, so as to avoid excessive extrusion force of the suction cup 10 on the metal part, which makes the metal part unable to move and affects the adjustment of the position of the metal part.

[0047] As the connecting ring 8 drives the parts on it to continue to move downward, the second spring 27 is gradually compressed, the transmission rod 25 drives the telescopic end of the first elastic telescopic rod 7 to shake and repeats the above process to adjust the position of the metal plate. When the inclined surface of the extrusion block 26 contacts the L-shaped plate 29, the extrusion block 26 pushes the L-shaped plate 29 to move to the left and compresses the third spring 30 until the lower side of the L-shaped plate 29 is separated from the support frame 23. The second spring 27 pushes the air pipe 9 downward through the connecting frame 11 (in this process, the L-shaped plate 29 will not move to the lower side of the support frame 23, and the L-shaped plate 29 is in contact with the side adjacent to the support frame 23), so that the extrusion force of the suction cup 10 on the metal part increases, completing the final fixation of the metal part, and then the linear slide group 5 drives the parts on it to move in the opposite direction and reset.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
