Description

Technical Field

[0001] The invention relates to the technical field of convex rice forming dies, and more specifically to a traceless convex rice forming die. Background Art

[0002] One of the main functions of a cam on a stamping is to serve as a positioning point. When two or more stampings need to be combined, the cam ensures that they are accurately aligned and fit together. Usually, the cam on one stamping will match the hole or slot on another stamping to achieve precise assembly. In sheet metal design, cams are often reserved for palletizing, transportation or installation, that is, a cam is punched directly on the product with a punch.

[0003] At present, when stamping a convex structure on the surface of a hardware material plate, it is usually necessary to place the hardware material plate on the lower die stripping plate of the punching machine, and drive the upper die base of the punching machine downward by hydraulic pressure, thereby applying pressure to the surface of the hardware material plate, and at the same time, the stripping spring at the bottom of the lower die stripping plate is contracted, so that the convex mold and the punch needle in the lower die base extend out of the top of the lower die stripping plate, and under the action of hydraulic pressure, the convex mold and the punch needle are punched into the interior of the hardware material plate, thereby forming a convex structure on the surface of the hardware material plate. Traditionally, the convex mold and the punch needle are usually fixed inside the lower die base. Although this can improve the integrity of the convex mold and the punch needle with the lower die base, it also increases Strong structural strength and stability, but it also makes it inconvenient to adjust the convex rice mold and the punch needle according to the specific material of the hardware material plate. For example, aluminum plate and iron plate, under the condition of the same thickness, the toughness and yield strength of aluminum plate and iron plate are significantly different. Aluminum plate has higher toughness, so even if the convex rice mold and the punch needle punch into it at the same time, it is not easy to cause it to break and damage. Compared with aluminum plate, iron plate has lower toughness. When the convex rice mold and the punch needle punch into it at the same time, it is easy to cause excessive local stress of the iron plate and cause damage to the stamping position. Especially when the convex rice area required for stamping is smaller, it is more likely to cause excessive stress concentration. In view of this, we propose a traceless convex rice forming mold. Summary of the invention

[0004] The purpose of the present invention is to provide a traceless convex forming die to solve the technical problem that the aluminum plate has higher toughness, so even if the convex die and the punch needle punch into it at the same time, it is not easy to cause it to break or be damaged, while the iron plate has lower toughness than the aluminum plate, and when the convex die and the punch needle punch into it at the same time, it is easy to cause excessive local stress on the iron plate and cause damage to the stamping position.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a traceless convex rice forming die, comprising a weighted bottom plate with a punch body arranged on one side of the upper end surface;

[0006] A punching assembly for punching a convex structure on the surface of a plate is arranged on the top of the punching machine body, and a supporting assembly is arranged on one side of the punching machine body;

The structure in which the convex ring slightly protrudes from the top of the punch needle is beneficial for first contacting the iron metal plate and applying pressure, thereby increasing the contact area and reducing the contact pressure. The convex ring contacts the iron metal plate to deform it and release the stress, and then the punch needle contacts the iron metal plate to realize the convex processing, avoiding the punch needle and the convex ring from contacting at the same time, resulting in excessive concentration of stress at the contact position and causing damage to the iron metal plate, which is beneficial to achieving the effect of dual-mode convex forming processing.

An upper die rod is detachably installed on the bottom of the stamping seat. An upper die plane is formed at the center of the bottom end of the upper die rod.

[0020] A method for using a traceless convex rice forming mold comprises the following steps:

[0021] S1, convex rice forming processing on the surface of aluminum plate;

[0022] S1.1, stamping;

[0023] The stamping plate made of aluminum material is placed on the supporting platform. Under normal circumstances, the top of the convex rice ring and the punch needle are at the same plane height. By starting the motor 1, the speed reducer is used to slow down the transmission wheel to rotate slowly, and the transmission shaft is driven by the transmission belt to rotate slowly, and the driving disk is driven by the transmission shaft to rotate, and the eccentric wheel is eccentrically rotated with the driving disk as the axis. Through the rotation cooperation of the eccentric wheel and the turntable, the limit cooperation of the limit plate and the limit seat, and the active connection between the universal ball body and the universal ball seat, the stamping component is driven by the motor 1 to perform reciprocating downward pressing and lifting actions. In the process of pressing the stamping component, the upper die plane at the bottom end of the upper die rod contacts the surface of the stamping plate made of aluminum material, and presses the stamping plate, so that the convex rice ring and the punch needle are synchronously pressed into the stamping plate, so that the aluminum material in the stamping plate is pressed into the gap between the convex rice ring and the punch needle under the action of pressure to form a convex rice structure;

[0024] When the upper die plane at the bottom of the upper die rod contacts the stamping plate and applies pressure, the stripper plate moves downward under the pressure, causing the serpentine spring to deform under pressure until the stripper plate moves down to be flush with the surface of the support platform and is stamped into place. The height difference between the stripper plate and the support platform is the stroke length of the convex structure.

[0025] S1.2, maintain pressure;

[0026] After the convex rice on the surface of the stamping plate is formed, the motor is turned off so that the upper die plane stays in place to continuously maintain the pressure on the stamping plate;

[0027] S1.3, leveling the convex rice;

[0028] Starting the second motor causes the machine shaft to rotate and drives the driving gear to rotate, which drives the driven gear to rotate through the meshing action of the gears, thereby causing the sun gear and the punch needle to rotate. At this time, the punch needle is in a clockwise rotation state. Limited by the clamping and limiting action of the ratchet, the rotation of the punch needle will drive the triangular bracket to rotate as a whole, thereby causing the planetary gear to revolve around the axis of the punch needle while rotating on itself, thereby causing the punch needle and the cam ring to be in a rotating state. The rotation of the punch needle and the cam ring realizes the rotation and leveling of the inner wall of the cam structure at the bottom of the stamping plate, repairs the unevenness on the inner wall of the cam structure caused by defects on the surface of the cam ring and the punch needle due to long-term use, and improves the processing quality of the cam stamping.

[0029] S1.4, material return;

[0030] After the convex rice at the bottom of the stamping plate is stamped and formed, the motor 1 is started again, and the stamping part is driven to rise under the rotation of the eccentric wheel. When the stamping part rises, the elastic force stored in the serpentine spring is released, and the convex rice structure of the stamping plate is separated from the convex rice ring and the punching needle through the stripping plate;

[0031] S2, convex rice forming processing on the surface of iron plate;

[0032] S2.1, drop adjustment;

[0033] Start the second motor to rotate the shaft and drive the driving gear to rotate, and drive the driven gear to rotate through the meshing action of the gears, so that the sun gear and the punch needle rotate. At this time, the punch needle is in a counterclockwise rotation state. In the counterclockwise rotation state, there is no interference between the ratchet wheel and the ratchet teeth. The cylindrical cam synchronizes the punch needle to rotate. Under the rotation of the cylindrical cam, the spherical block is forced to move in the guide groove, thereby forcing the triangular bracket 1 to climb as a whole, so that the convex rice ring protrudes slightly from the top of the punch needle. Turn off the second motor, so that the convex rice ring protrudes from the top of the punch needle and remains stationary.

[0034] S2.2, stamping;

[0035] The stamping plate made of iron material is placed on the supporting platform. The top of the convex ring slightly protrudes from the top of the punch needle in the drop state. By starting the motor 1, the transmission wheel is slowed down by the reducer, and the transmission shaft is driven to rotate slowly by the transmission belt. The drive disk is driven to rotate by the transmission shaft, and the eccentric wheel is rotated eccentrically with the drive disk as the axis. Through the rotation cooperation of the eccentric wheel and the turntable, the limit cooperation of the limit plate and the limit seat, and the active connection between the universal ball body and the universal ball seat, the stamping component is driven by the motor 1 to perform reciprocating downward and upward movements. In the process of pressing the stamping component, The upper die plane at the bottom end of the upper die rod contacts the surface of the stamping plate made of iron material and applies pressure to the stamping plate, so that the convex ring is first pressed into the stamping plate. Since the stamping plate is in a ring-shaped structure, it has a larger contact area than the top of the punch needle, thereby reducing the contact pressure during the stamping process. The stamping plate is first deformed at the location where the convex ring is squeezed and the stress is released through deformation. As the upper die plane continues to apply pressure to the stamping plate, the punch needle is pressed into the stamping plate, so that the iron material in the stamping plate is pressed into the gap between the convex ring and the punch needle under the action of pressure, forming a convex structure.

[0036] When the upper die plane at the bottom of the upper die rod contacts the stamping plate and applies pressure, the stripper plate moves downward under the pressure, causing the serpentine spring to deform under pressure until the stripper plate moves down to be flush with the surface of the support platform and is stamped into place. The height difference between the stripper plate and the support platform is the stroke length of the convex structure.

[0037] S2.3, maintain pressure;

[0038] After the convex rice on the surface of the stamping plate is formed, the motor is turned off so that the upper die plane stays in place to continuously maintain the pressure on the stamping plate;

[0039] S2.4, convex rice filling;

[0040] Starting the second motor causes the machine shaft to rotate and drives the driving gear to rotate, which drives the driven gear to rotate through the meshing action of the gears, thereby causing the sun gear and the punch needle to rotate. At this time, the punch needle is in a clockwise rotation state. Limited by the clamping and limiting action of the ratchet, the rotation of the punch needle will drive the triangular bracket to rotate as a whole, thereby causing the planetary gear to revolve around the axis of the punch needle while rotating on itself, thereby causing the punch needle and the cam ring to be in a rotating state. The rotation of the punch needle and the cam ring realizes the rotation and leveling of the inner wall of the cam structure at the bottom of the stamping plate, repairs the unevenness on the inner wall of the cam structure caused by defects on the surface of the cam ring and the punch needle due to long-term use, and improves the processing quality of the cam stamping.

[0041] S2.5, material return;

[0042] After the convex rice at the bottom of the stamping plate is stamped and formed, continue to start motor 1, and the stamping component is driven to rise under the rotation of the eccentric wheel. When the stamping component rises, the elastic force stored in the serpentine spring is released, and the convex rice structure of the stamping plate is separated from the convex rice ring and the punching needle through the stripping plate.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The present invention designs movable parts and driving parts. Under normal conditions, the convex ring is flush with the top of the punch needle, which is used for convex forming processing of aluminum metal plates with good toughness. The second motor can also be started to rotate the machine shaft and drive the driving gear to rotate, and the driven gear is driven to rotate through the meshing action of the gears, so that the sun gear and the punch needle rotate. At this time, the punch needle is in a counterclockwise rotation state. In the counterclockwise rotation state, there is no interference between the ratchet wheel and the ratchet teeth. The cylindrical cam synchronizes the rotation of the punch needle. Under the rotation action of the cylindrical cam, the spherical block is forced to move in the guide groove, thereby forcing the triangular bracket to climb as a whole, so that the convex ring is slightly protruding from the top of the punch needle, which is used for processing iron metal plates with weaker toughness than aluminum metal plates. The structure in which the convex ring slightly protrudes from the top of the punch needle is conducive to first contacting the iron metal plate and applying pressure, thereby increasing the contact area and reducing the contact pressure. The convex ring contacts the iron metal plate to deform it and release the stress, and then the punch needle contacts the iron metal plate to realize the convex processing, avoiding the punch needle and the convex ring from contacting at the same time, resulting in excessive concentration of stress at the contact position and causing damage to the iron metal plate, which is conducive to achieving the effect of dual-mode convex forming processing and solving the problem that the aluminum plate has high toughness, so even if the convex mold and the punch needle punch into it at the same time, it is not easy to cause it to break and damage. The iron plate has lower toughness than the aluminum plate. When the convex mold and the punch needle punch into it at the same time, it is easy to cause excessive local stress on the iron plate and cause damage to the stamping position.

[0045] 2. The present invention also designs a ratchet and a rotating shaft, and starts the second motor to rotate the machine shaft and drive the driving gear to rotate, and drives the driven gear to rotate through the meshing action of the gears, thereby rotating the sun gear and the punch needle. At this time, the punch needle is in a clockwise rotation state. Limited by the clamping and limiting effect of the ratchet, the rotation of the punch needle will drive the triangular bracket to rotate as a whole, so that the planetary gear revolves around the axis of the punch needle and rotates at the same time, so that the punch needle and the cam ring are both in a rotating state, so that the rotation of the punch needle and the cam ring can realize the rotation and leveling of the inner wall of the cam structure at the bottom of the stamping plate, and repair the unevenness on the inner wall of the cam structure caused by defects on the surface of the cam ring and the punch needle due to long-term use, thereby achieving the effect of improving the cam forming processing quality.

[0069] Embodiment 1:

[0070] A method for using a traceless convex rice forming mold comprises the following steps:

[0071] S1, convex rice forming processing on the surface of aluminum plate;

[0072] S1.1, stamping;

[0073] The stamping plate 14 made of aluminum material is placed on the supporting platform 802. Under normal conditions, the convex ring 1211 and the top of the punching needle 1307 are at the same plane height. By starting the motor 601, the transmission wheel 603 is slowed down by the speed reducer 602, and the transmission shaft 605 is driven to rotate slowly through the transmission belt 604, and the driving disk 606 is driven to rotate through the transmission shaft 605, and the eccentric wheel 607 is eccentrically rotated with the driving disk 606 as the axis. Through the rotation cooperation of the eccentric wheel 607 and the rotating disk 608, and the limiting cooperation of the limiting plate 612 and the limiting seat, The movable connection between the universal ball body and the universal ball seat 611 enables the stamping component 7 to perform reciprocating pressing and lifting actions under the driving action of the motor 601. During the pressing process of the stamping component 7, the upper die plane 704 at the bottom end of the upper die rod 703 contacts the surface of the stamping plate 14 made of aluminum material and applies pressure to the stamping plate 14, so that the convex ring 1211 and the punch needle 1307 are synchronously pressed into the stamping plate 14, so that the aluminum material in the stamping plate 14 is pressed into the gap between the convex ring 1211 and the punch needle 1307 under the action of pressure, forming a convex structure;

[0074] When the upper die plane 704 at the bottom of the upper die rod 703 contacts the stamping plate 14 and applies pressure, the stripping plate 1003 moves downward under the pressure, causing the serpentine spring 1002 to deform under pressure, until the stripping plate 1003 moves downward to be flush with the surface of the supporting platform 802 and is stamped into place. The height difference between the stripping plate 1003 and the supporting platform 802 is the stroke length of the convex structure.

[0075] S1.2, maintain pressure;

[0076] After the convex rice on the surface of the stamping plate 14 is formed, the motor 1 601 is turned off, so that the upper die plane 704 stays in place to continuously maintain the pressure on the stamping plate 14;

[0077] S1.3, leveling the convex rice;

[0078] Start the second motor 1101, so that the machine shaft 1102 rotates and drives the driving gear 1103 to rotate, and drives the driven gear 1305 to rotate through the gear meshing action, so that the sun gear 1302 and the punch needle 1307 rotate. At this time, the punch needle 1307 is in a clockwise rotation state. Limited by the clamping and limiting effect of the ratchet 1209, the rotation of the punch needle 1307 will drive the triangle bracket 1201 to rotate as a whole, so that the planetary gear 1303 revolves around the axis of the punch needle 1307 and rotates at the same time, so that the punch needle 1307 and the convex rice ring 1211 are both in a rotating state, so that the rotation of the punch needle 1307 and the convex rice ring 1211 can realize the rotation and leveling of the inner wall of the convex rice structure at the bottom of the stamping plate 14, and repair the unevenness on the inner wall of the convex rice structure caused by the surface defects of the convex rice ring 1211 and the punch needle 1307 due to long-term use, thereby improving the processing quality of the convex rice stamping;

[0079] S1.4, material return;

[0080] After the convex rice at the bottom of the stamping plate 14 is stamped and formed, the motor 1 601 is started again, and the stamping component 7 is driven to rise under the rotation of the eccentric wheel 607. When the stamping component 7 rises, the elastic force stored in the serpentine spring 1002 is released, and the convex rice structure of the stamping plate 14 is separated from the convex rice ring 1211 and the punching needle 1307 through the stripping plate 1003;

[0081] Embodiment 2:

[0082] A method for using a traceless convex rice forming mold comprises the following steps:

[0083] S2, convex rice forming processing on the surface of iron plate;

[0084] S2.1, drop adjustment;

[0085] Start the second motor 1101, so that the machine shaft 1102 rotates and drives the driving gear 1103 to rotate, and drives the driven gear 1305 to rotate through the meshing action of the gears, so that the sun gear 1302 and the punching needle 1307 rotate. At this time, the punching needle 1307 is in a counterclockwise rotation state. In the counterclockwise rotation state, there is no interference between the ratchet 1308 and the ratchet 1209. The cylindrical cam 1309 synchronizes the punching needle 1307 to rotate. Under the rotation of the cylindrical cam 1309, the spherical block 1204 is forced to move in the guide groove 1310, thereby forcing the triangular bracket 1201 to climb as a whole, so that the convex rice ring 1211 slightly protrudes from the top of the punching needle 1307, and the second motor 1101 is turned off, so that the convex rice ring 1211 protrudes from the top of the punching needle 1307 and remains stationary;

[0086] S2.2, stamping;

[0087] A stamping plate 14 made of iron material is placed on a supporting platform 802, and the top of the convex ring 1211 slightly protrudes from the top of the punching needle 1307 in the drop state. By starting the motor 601, the transmission wheel 603 is slowed down by the speed reducer 602, and the transmission shaft 605 is driven to rotate slowly by the transmission belt 604, and the driving disk 606 is driven to rotate by the transmission shaft 605, and the eccentric wheel 607 is rotated eccentrically with the driving disk 606 as the axis. Through the rotation cooperation of the eccentric wheel 607 and the turntable 608, the limiting cooperation of the limiting plate 612 and the limiting seat, and the active connection between the universal ball body and the universal ball seat 611, the stamping component 7 is driven by the motor 601 to perform reciprocating downward and lifting actions. During the process, the upper die plane 704 at the bottom end of the upper die rod 703 contacts the surface of the stamping plate 14 made of iron material, and applies pressure to the stamping plate 14, so that the convex ring 1211 is first pressed into the stamping plate 14. Since the stamping plate 14 is annular in structure, it has a larger contact area than the top of the punch needle 1307, thereby reducing the contact pressure during the stamping process. The stamping plate 14 is first deformed at the location where the convex ring 1211 is squeezed, and the stress is released through the deformation. As the upper die plane 704 continues to apply pressure to the stamping plate 14, the punch needle 1307 is pressed into the stamping plate 14, so that the iron material in the stamping plate 14 is pressed into the gap between the convex ring 1211 and the punch needle 1307 under the action of pressure, forming a convex structure.

[0088] When the upper die plane 704 at the bottom of the upper die rod 703 contacts the stamping plate 14 and applies pressure, the stripping plate 1003 moves downward under the pressure, causing the serpentine spring 1002 to deform under pressure, until the stripping plate 1003 moves downward to be flush with the surface of the supporting platform 802 and is stamped into place. The height difference between the stripping plate 1003 and the supporting platform 802 is the stroke length of the convex structure.

[0089] S2.3, maintain pressure;

[0090] After the convex rice on the surface of the stamping plate 14 is formed, the motor 1 601 is turned off, so that the upper die plane 704 stays in place to continuously maintain the pressure on the stamping plate 14;

[0091] S2.4, convex rice filling;

[0092] Start the second motor 1101, so that the machine shaft 1102 rotates and drives the driving gear 1103 to rotate, and drives the driven gear 1305 to rotate through the gear meshing action, so that the sun gear 1302 and the punch needle 1307 rotate. At this time, the punch needle 1307 is in a clockwise rotation state. Limited by the clamping and limiting effect of the ratchet 1209, the rotation of the punch needle 1307 will drive the triangle bracket 1201 to rotate as a whole, so that the planetary gear 1303 revolves around the axis of the punch needle 1307 and rotates at the same time, so that the punch needle 1307 and the convex rice ring 1211 are both in a rotating state, so that the rotation of the punch needle 1307 and the convex rice ring 1211 can realize the rotation and leveling of the inner wall of the convex rice structure at the bottom of the stamping plate 14, and repair the unevenness on the inner wall of the convex rice structure caused by the surface defects of the convex rice ring 1211 and the punch needle 1307 due to long-term use, thereby improving the processing quality of the convex rice stamping;

[0093] S2.5, material return;

[0094] After the convex portion at the bottom of the stamping plate 14 is stamped and formed, continue to start the motor 601, and the stamping component 7 is driven to rise under the rotation of the eccentric wheel 607. When the stamping component 7 rises, the elastic force stored in the serpentine spring 1002 is released, and the convex portion structure of the stamping plate 14 is separated from the convex portion ring 1211 and the punching needle 1307 through the stripping plate 1003.
