Abstract

The present application provides a kind of stamping equipment with multiple stamping positions;The present application pulls and winds raw material steel strip through the material passage by discharging die set, so that the product raw material on the raw material steel strip is continuously sent into the stamping position for the stamping of the die set, while the post-stamping material is also removed from the material passage along with the movement of the raw material steel strip. At this time, the knockout die set knocks the post-stamping material off the raw material steel strip to complete the material removal. Therefore, the product raw material does not need to be moved between different stamping positions by a handling mechanism or an operator, improving production efficiency and simplifying the production process. The present application belongs to the technical field of stamping dies.

Description

Technical Field

[0001] This invention belongs to the technical field of stamping dies, and particularly relates to a stamping device with multiple stamping positions. Background Technology

[0002] Stamping equipment, also known as a press, stamping machine, hydraulic press, or hydraulic press, is a device that applies pressure to metal materials by driving the mold to open and close, so as to achieve plastic forming of metal materials. It is mainly used in the production of parts for automobile manufacturing, home appliances, electronics, and aerospace, such as steel plate forming, head manufacturing, and container pressing.

[0003] In conventional stamping equipment, raw materials are mainly transported to the mold by a handling mechanism (clamps or suction cups that can move along the xyz axis) or by an operator. After the mold plastically shapes the raw materials, the handling mechanism or operator removes the plastically shaped product from the mold. Finally, another raw material is transported to the mold for plastic shaping. Therefore, loading and unloading are cumbersome and inefficient.

[0004] In addition, traditional handling mechanisms require the use of xyz axis drive modules to drive the fixtures or suction cups to move between the lower and upper modules in order to move the product raw materials to the pressing position and remove the stamped material from the pressing position. Therefore, the range of motion of the xyz axis drive module needs to be greater than that of the lower and upper modules, resulting in high equipment cost and large equipment space occupation.

[0005] Finally, since the lower and upper modules need to open and close during operation, and the conveying mechanism needs to use the xyz axis to drive the module to move the clamp or suction cup between the lower and upper modules, the opening and closing movements of the lower and upper modules can easily conflict with the movement of the clamp or suction cup. Summary of the Invention

[0006] The purpose of this invention is to provide a stamping device with multiple stamping positions to solve the technical problems described in the background art.

[0007] A stamping device with multiple stamping stations includes:

[0008] The feeding module winds up the raw material steel strip, and the part of the raw material steel strip is the product raw material.

[0009] The mold module has a material passage running through it, and the material passage is equipped with several stamping positions, which are used to place the product raw material to be stamped.

[0010] The discharge module is where the raw steel strip is pulled out from the feeding module, passes through the material channel, and is wound onto the discharge module.

[0011] The knockdown module is located between the material passage and the discharge module.

[0012] The material strip is pulled and wound up by the discharge module, so that each part of the material strip passes through the feed channel, so as to continuously feed the product material on the material strip into the stamping position for the die module to stamp and form the stamped material. At the same time, the stamped material is moved out of the feed channel along with the material strip. At this time, the knocking module knocks the stamped material off the material strip to complete the unloading.

[0013] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0014] 1. Since the raw material steel strip is pulled out from the feeding module, passes through the feed channel and is wound onto the output module, when the product raw material is stamped to form the stamped material, it is only necessary to pull and wind the raw material steel strip through the output module to allow each part of the raw material steel strip to pass through the feed channel. This enables the continuous and orderly feeding of several product raw materials into each stamping position for the feeding die module to stamp and form the stamped material, thereby completing the feeding action. Therefore, it is not necessary to move the product raw materials from different stamping positions through a handling mechanism or operator, thereby improving production efficiency and simplifying the production process.

[0015] 2. After the product raw material is stamped, the discharge module pulls and rewinds the raw material steel strip. The stamped material also moves out of the feed channel along with the raw material steel strip. At this time, the knocking module knocks the stamped material off the raw material steel strip to complete the unloading action. Therefore, it further improves production efficiency and simplifies the production process.

[0016] 3. Since there is no need to set up a conveying mechanism between each stamping station, as well as at the loading and unloading ends, it is possible to load the product raw materials, send the stamped materials to each stamping station, and unload the stamped materials, thereby further reducing the manufacturing cost and size of the equipment.

[0017] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0018] In some embodiments, the mold module includes:

[0019] The lower module has a material passage that runs through the top of it.

[0020] The upper module is equipped with a punch. The upper module can move closer to or open with the lower module so that the punch can press the product raw material located in the stamping position to form the stamped material.

[0021] Based on the above technical solution, the product raw material located in the stamping position is stamped and formed by the opening and closing movement of the module and the lower module.

[0022] In some implementations, when it is necessary to stamp the product raw materials in different modes, traditional stamping equipment, after stamping the product raw materials into stamped materials, generally requires the stamped materials to be transported to another stamping equipment for secondary stamping by a handling mechanism (clamps or suction cups that can move along the xyz axis) or an operator, which results in low production efficiency and cumbersome processes; therefore, the present invention further provides the following technical solutions.

[0023] Furthermore, the present invention provides a plurality of stamping positions arranged in the feed channel. The stamping positions are used to place the raw material to be stamped or the stamped material. Both sides of the stamping position are connected to another adjacent stamping position. When the raw material is pushed into the feed channel, the raw material will push the stamped material in the stamping position to the next adjacent stamping position for secondary stamping by the punch, or push it out from another opening of the feed channel.

[0024] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0025] 1. When the feeding module pushes another product material into the feed channel, the other product material pushes the punched material in the stamping position to the next stamping position adjacent to the stamping position for secondary stamping by the punch. The punched material in the last stamping position is pushed out from another opening of the feed channel by the punched material in the previous stamping position adjacent to the stamping position, thus completing the unloading. Therefore, when it is necessary to stamp the raw material in different modes, it is not necessary to move the punched material from different stamping positions through the handling mechanism or operator, thereby improving production efficiency and simplifying the production process.

[0026] 2. Since there is no need to set up a conveying mechanism between each stamping station, as well as at the loading and unloading ends, it is possible to load the product raw materials, send the stamped materials to each stamping station, and unload the stamped materials, thereby further reducing the manufacturing cost and size of the equipment.

[0027] In some embodiments, the stamping position is provided with a lower elastic component, which pushes a lower top block;

[0028] When the lower and upper dies come together, the product material or post-stamping material pushes the lower ejector block into the lower die. When the lower and upper dies open up, the lower elastic component pushes the lower ejector block to lift the post-stamping material from the stamping position.

[0029] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0030] 1. After the lower and upper dies come together, the product raw material or stamped material is pushed into the lower die by the pressure generated by the lower and upper dies coming together. When the punch presses the product raw material or stamped material, the lower ejector block is avoided from causing pressure damage to the product raw material or stamped material.

[0031] 2. After the punch completes the stamping of the product raw material or the post-stamping material, and the lower die and the upper die open to each other, the lower elastic component pushes the lower top block to lift the post-stamping material from the stamping position, thereby preventing the post-stamping material from sticking to the stamping position and being unable to move.

[0032] In some embodiments, the lower top block is a roller that contacts the raw material steel strip, the product raw material, or the stamped material;

[0033] Based on the above technical solution, when the raw material steel strip, product raw material or stamped material moves in the material passage, the resistance generated by the friction between the lower top block and the raw material steel strip, product raw material or stamped material can be reduced, thereby protecting the product raw material and stamped material.

[0034] In some embodiments, an information strip is provided on the side of the raw material steel strip, the information strip extends from one end of the raw material steel strip to the other end, the surface of the information strip is provided with a magnetic coating, the magnetic field strength and magnetic poles of the magnetic coating change continuously and irregularly, and magnetic sensors for contacting the information strip are distributed at different positions of the material passage.

[0035] As the raw steel strip moves within the feed channel, the magnetic sensor continuously senses the magnetic field strength and magnetic poles on the information band, thereby positioning all parts of the raw steel strip based on the changes in the magnetic field strength and magnetic poles.

[0036] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0037] 1. It can achieve blind-spot-free positioning of all parts of the raw steel strip;

[0038] 2. Compared to the traditional method of arranging several storage units into information codes (binary or digital codes), it increases the amount of information stored.

[0039] In some embodiments, the stamping equipment provided by the present invention further includes: a positioning system, wherein a first magnetic sensor is provided at the beginning of the material passage, the first magnetic sensor is used to pre-acquire the magnetic field strength and magnetic pole changes of the information band and transmit them to the positioning system, the positioning system converts the magnetic field strength and magnetic pole changes sensed by the first magnetic sensor into a continuously changing waveform for reference, the magnetic sensor acquires the magnetic field strength and magnetic pole changes of the information band and transmits them to the positioning system for comparison, and the positioning system converts the magnetic field strength and magnetic pole changes acquired by the magnetic sensor into a continuously changing waveform for comparison.

[0040] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0041] 1. When the continuously changing waveform of one of the magnetic sensors matches a certain segment of the continuously changing waveform used as a reference, the position of each part of the raw steel strip is determined, thereby achieving accurate and efficient positioning of each part of the raw steel strip.

[0042] 2. The speed at which the raw steel strip moves through the feed channel is determined by the time it takes for the continuous waveform used for reference to appear and match the continuous waveform used for comparison. This facilitates the monitoring of equipment performance and the optimization of production plans and capacity expectations.

[0043] In some embodiments, the stamping equipment provided by the present invention further includes a current controller and a coil module. The coil module is located between the material passage and the feeding module. The coil module is used to contact the information tape. The coil module is electrically connected to the current controller. The magnetic coating contains a magnetic powder layer bonded by an adhesive.

[0044] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0045] 1. When the information strip slides past the coil module, the current controller supplies different currents to the coil module, so that the coil module adjusts and arranges the magnetic field change law of the magnetic coating, thereby editing and positioning information for different parts of the raw steel strip;

[0046] 2. The positioning system converts different currents supplied to the coil module by the current controller into another continuously changing waveform for reference. When the continuously changing waveform of one of the magnetic sensors matches a certain segment of the continuously changing waveform used as a reference, the position of each part of the raw material steel strip is determined, thereby achieving accurate and efficient positioning of each part of the raw material steel strip.

[0047] 3. The moving speed of the raw steel strip in the feed channel can be determined by the time from the appearance of another continuously changing waveform used for reference to the time it matches the continuously changing waveform being compared. This facilitates the monitoring of equipment performance and the optimization of production plans and capacity expectations.

[0048] In some embodiments, the upper module is provided with a first elastic component, which pushes a liftable stop plate. The punch passes through the stop plate. When the punch presses the product raw material or the post-punching material, the first elastic component pushes the stop plate to fit with the product raw material and the post-punching material.

[0049] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0050] 1. It can prevent the lower and upper dies from over-closing, which could damage the raw materials or post-punching materials;

[0051] 2. When the punch presses the product raw material or the material after punching, the first elastic component pushes the stop plate to contact the product raw material or the material after punching, thereby fixing the product raw material or the material after punching and preventing the product raw material or the material after punching from shifting.

[0052] 3. When the lower and upper modules are over-closed, the closing force can be buffered, thereby protecting the lower and upper modules, as well as the raw materials and post-punching materials.

[0053] In some embodiments, the stop plate is provided with a second elastic component, which pushes an outward push block;

[0054] When the lower and upper modules come together, the product raw material or post-punching material pushes the push block into the stop plate. When the lower and upper modules open, the second elastic component pushes the push block out of the stop plate to push the post-punching material away from the stop plate.

[0055] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0056] 1. After the lower and upper dies come together, the product raw material or stamped material is pushed into the stop by the pressure generated by the lower and upper dies coming together. This prevents the outer push block from causing pressure damage to the product raw material or stamped material when the punch is pressing the product raw material or stamped material.

[0057] 2. After the punch completes the stamping of the product raw material or the post-stamped material, and the lower die and the upper die open to each other, the second elastic group pushes the outer push block to push the post-stamped material away from the stop plate, thereby preventing the post-stamped material from sticking to the stop plate and being unable to move.

[0064] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided with reference to the accompanying drawings.

[0065] like Figures 1 to 3 As shown in the figure, this specific embodiment provides a stamping device with multiple stamping stations, which includes:

[0066] The mold module includes a lower mold 1 and an upper mold 2 that can be brought close together or opened. The top of the lower mold 1 has a material passage 11 through it. The material passage 11 is provided with a number of stamping positions 12. The stamping positions 12 are used to place the product raw material 61 to be stamped. The upper mold 2 is provided with a punch 21.

[0067] The feeding module 3 is located next to one of the openings of the feed channel 11. The feeding module 3 is used to continuously push the product raw material 61 to be stamped into the stamping position 12 in the feed channel 11 for the punch 21 to stamp and form the stamped material 62. After the product raw material 61 is pushed into the feed channel 11, the product raw material 61 will push the stamped material 62 in the stamping position 12 out from the other opening of the feed channel 11.

[0068] When a large batch of product raw materials 61 needs to be pressed and plastically molded, the feeding module 3 pushes the product raw materials 61 into the feed channel 11. At this time, the product raw materials 61 are located in the stamping position 12, thus completing the loading. The lower module 1 and the upper module 2 move closer together, so that the punch 21 stamps the product raw materials 61 in the stamping position 12 to form the stamped material 62. Then, the lower module 1 and the upper module 2 open up to allow the feeding module 3 to push another product raw material 61 into the feed channel 11. At this time, the other product raw material 61 is located in the stamping position 12. Simultaneously, the other product raw material 61 pushes the stamped material 62 in the stamping position 12 out from another opening of the feed channel 11, thus completing the unloading. Therefore, without the need for a handling mechanism or operator to move the product raw materials 61 and the stamped material 62 between the lower module 1 and the upper module 2, loading and unloading can be achieved, thereby improving the convenience and efficiency of loading and unloading.

[0069] Since the stamping equipment does not require a handling mechanism, it can still achieve loading and unloading, thereby reducing the manufacturing cost and space occupation of the equipment. Furthermore, since there is no need to move the raw material or the stamped material 62 around during loading and unloading, the loading and unloading steps are simplified, thus improving loading and unloading efficiency. In addition, since the stamping equipment does not require a handling mechanism, the possibility of conflict with the opening and closing movements of the lower die group 1 and the upper die group 2 can be effectively avoided during loading and unloading.

[0070] In some embodiments, the feed channel 11 is provided with a plurality of stamping positions 12. The stamping positions 12 are used to place the product raw material 61 to be stamped or the stamped material 62. Each stamping position 12 is connected to another adjacent stamping position 12 on both sides. When the product raw material 61 is pushed into the feed channel 11, the product raw material 61 will push the stamped material 62 in the stamping position 12 to the next adjacent stamping position 12 for secondary stamping by the punch 21, or push it out from another opening of the feed channel 11.

[0071] When the feeding module 3 pushes another product material 61 into the feed channel 11, the other product material 61 pushes the punched material 62 in the stamping position 12 to the next stamping position 12 adjacent to the stamping position 12 for the punch 21 to stamp a second time. The punched material 62 in the last stamping position 12 is pushed out from another opening of the feed channel 11 by the punched material 62 in the previous stamping position 12 adjacent to the stamping position 12, thus completing the unloading. Therefore, when it is necessary to stamp the raw material in different modes, it is not necessary to move the punched material 62 from different stamping positions 12 through the handling mechanism or operator, thereby improving production efficiency and simplifying the production process.

[0072] Since there is no need to set up a conveying mechanism between each stamping station 12, as well as at the loading and unloading ends, it is possible to load the product raw material 61, send the stamped material 62 to each stamping station 12, and unload the stamped material 62, thereby further reducing the manufacturing cost and size of the equipment.

[0073] In some embodiments, the stamping equipment further includes a discharge module 4 located next to another opening of the feed channel 11. The discharge module 4 is used to pull the stamped material 62 out from the other opening of the feed channel 11, thereby preventing the stamped material 62 from getting stuck in the other opening of the feed channel 11 and thus improving the stability of the stamped material 62.

[0074] In some embodiments, the feeding module 3 is a front winding machine, the discharging module 4 winds up the raw material steel strip 6, the product raw material 61 is one part of the raw material steel strip 6, the discharging module 4 is a rear winding machine, the raw material steel strip 6 is pulled out from the feeding module 3, passes through the feed channel 11 and is wound onto the discharging module 4, and the discharging module 4 is used to pull and wind up the raw material steel strip 6.

[0075] Therefore, by controlling the unwinding speed of the raw material steel strip 6 through the feeding module 3, and simultaneously winding the raw material steel strip 6 through the discharge module 4, the product raw material 61 can be fed into the feed channel 11 in a stable and flat manner, the stamped material 62 can be sent to each stamping position 12, and the material can be unloaded.

[0076] In some embodiments, a knocking-off module 5 is provided between the other opening of the feed channel 11 and the discharge module 4. The knocking-off module 5 is used to knock the punched material 62 pulled out from the other opening of the feed channel 11 away from the raw material steel strip 6. After the punched material 62 is pulled out from the other opening of the feed channel 11, it can be removed from the raw material steel strip 6, thereby facilitating the centralized collection and management of the punched material 62 that has been completed.

[0077] In some embodiments, the stamping position 12 is provided with a lower elastic component 13, which pushes a lower push block 14. When the lower die 1 and the upper die 2 are close together, the product raw material 61 or the stamped material 62 pushes the lower push block 14 into the lower die 1, and when the lower die 1 and the upper die 2 are open, the lower elastic component 13 pushes the lower push block 14 to lift the stamped material 62 from the stamping position 12.

[0078] After the lower die 1 and the upper die 2 come together, the product raw material 61 or the stamped material 62 is pushed into the lower die 14 by the pressing force generated by the lower die 1 and the upper die 2 coming together. This avoids the lower ejector block 14 causing pressure damage to the product raw material 61 or the stamped material 62 when the punch 21 is pressing the product raw material 61 or the stamped material 62.

[0079] After the punch 21 completes the stamping of the product raw material 61 or the stamped material 62, and the lower die 1 and the upper die 2 open up to each other, the lower elastic component 13 pushes the lower top block 14 to lift the stamped material 62 from the stamping position 12, thereby preventing the stamped material 62 from sticking to the stamping position 12 and being unable to move.

[0080] In some embodiments, the lower top block 14 is a roller that contacts the raw material steel strip 6, the product raw material 61, or the stamped material 62. This reduces the resistance generated by friction between the lower top block 14 and the raw material steel strip 6, the product raw material 61, or the stamped material 62 as they move within the feed channel 11, thereby protecting the product raw material 61 and the stamped material 62.

[0081] In some embodiments, an information strip 63 is provided on the side of the steel strip, the information strip 63 extends from one end of the raw material steel strip 6 to the other end of the raw material steel strip 6, the surface of the information strip 63 is provided with a magnetic coating 64, the magnetic field strength and magnetic poles of the magnetic coating 64 change irregularly and continuously, and magnetic sensors 7 for contacting the information strip 63 are distributed at different positions of the material passage 11.

[0082] When the raw material steel strip 6 moves within the feed channel 11, the magnetic sensor 7 continuously and uninterruptedly senses the magnetic field strength and magnetic poles on the information strip 63, and registers the positioning and processing information of all parts of the raw material steel strip 6 based on the changes in the magnetic field strength and magnetic poles.

[0083] Therefore, it can achieve blind-spot-free positioning and processing information registration for all parts of the raw steel strip 6; in addition, compared with the traditional method of arranging several storage units into information codes (binary or digital codes), it increases the information storage capacity.

[0084] In some embodiments, the stamping equipment further includes a positioning system. A first magnetic sensor 7 is provided at the beginning of the material passage 11. The first magnetic sensor 7 is used to pre-acquire the changes in the magnetic field strength and magnetic poles of the information band 63 and transmit them to the positioning system. The positioning system converts the changes in the magnetic field strength and magnetic poles sensed by the first magnetic sensor 7 into a continuously changing waveform for reference. The magnetic sensor 7 acquires the changes in the magnetic field strength and magnetic poles of the information band 63 and transmits them to the positioning system for comparison. The positioning system converts the changes in the magnetic field strength and magnetic poles acquired by the magnetic sensor 7 into a continuously changing waveform for comparison.

[0085] When the continuously changing waveform of one of the magnetic sensors 7 matches a segment of the reference continuously changing waveform, the position of each part of the raw material steel strip 6 is determined, thereby achieving precise and efficient positioning of each part of the raw material steel strip 6. Furthermore, the moving speed of the raw material steel strip 6 in the feed channel 11 is determined based on the time from the appearance of the reference continuously changing waveform to its match with the compared continuously changing waveform, thus facilitating the monitoring of equipment performance and optimizing production plans and capacity expectations.

[0086] In some embodiments, the stamping equipment further includes a current controller and a coil module 72. The coil module 72 is located between the material passage 11 and the feeding module 3. The coil module 72 is used to contact the information tape 63. The coil module 72 is electrically connected to the current controller. The magnetic coating 64 contains a magnetic powder layer bonded by an adhesive. The magnetic powder layer is composed of numerous ferromagnetic nanoparticles (such as barium ferrite BFe).

[0087] As the information strip 63 slides past the coil module 72, the current controller supplies different currents to the coil module 72, causing the coil module 72 to generate a high magnetic field. This allows the magnetic powder layer of the magnetic coating 64 to be arranged with countless ferromagnetic nanoparticles, thus changing the magnetic field of the magnetic coating 64 and thereby editing and positioning information for different parts of the raw material steel strip 6.

[0088] The current controller supplies different currents to the coil module 72, which are then converted to a continuously changing waveform of another reference. When the continuously changing waveform of one of the magnetic sensors 7 matches a certain segment of the continuously changing waveform of the other reference, the position of each part of the raw material steel strip 6 is determined, thereby achieving precise and efficient positioning of each part of the raw material steel strip 6. In addition, the moving speed of the raw material steel strip 6 in the feed channel 11 is determined based on the time from the appearance of the continuously changing waveform of the other reference to its match with the continuously changing waveform of the comparison, thereby facilitating the monitoring of the equipment's performance status and optimizing production plans and capacity expectations.

[0089] In some embodiments, the upper module 2 is provided with a first elastic component 22, which pushes a movable stop plate 23. The punch 21 passes through the stop plate 23. When the punch 21 punches the product raw material 61 or the punched material 62, the first elastic component pushes the stop plate 23 to fit against the product raw material 61 and the punched material 62. Therefore, the stop plate 23 can prevent the lower module 1 and the upper module 2 from being over-closed, thus preventing damage to the product raw material 61 or the punched material 62. In addition, since the first elastic component 22 pushes the stop plate 23 to contact the product raw material 61 or the punched material 62 when the punch 21 punches it, the product raw material 61 or the punched material 62 is fixed, thereby preventing displacement of the product raw material 61 or the punched material 62.

[0090] When the lower module 1 and the upper module 2 are over-closed, the closing force can be buffered, thereby protecting the lower module 1, the upper module 2, the product raw material 61, and the stamped material 62.

[0091] In some embodiments, the stop plate 23 is provided with a second elastic component 24, which pushes an outward push block 25.

[0092] When the lower module 1 and the upper module 2 come together, the product raw material 61 or the post-punching material 62 pushes the push block 25 into the stop plate 23. When the lower module 1 and the upper module 2 open up to each other, the second elastic component 24 pushes the push block 25 out of the stop plate 23 to push the post-punching material 62 away from the stop plate 23.

[0093] After the lower module 1 and the upper module 2 come together, the product raw material 61 or the stamped material 62 is pushed into the stop by the pressing force generated by the lower module 1 and the upper module 2 coming together. This prevents the outer push block 25 from causing pressure damage to the product raw material 61 or the stamped material 62 when the punch 21 is pressing the product raw material 61 or the stamped material 62.

[0094] After the punch 21 completes the stamping of the product raw material 61 or the stamped material 62, and the lower die 1 and the upper die 2 open up to each other, the second elastic group pushes the outer push block 25 to push the stamped material 62 away from the stop plate 23, thereby preventing the stamped material 62 from sticking to the stop plate 23 and being unable to move.

[0095] To further explain the stamping equipment with multiple stamping positions described in this specific embodiment, the following examples are provided.

[0096] The following is Example 1

[0097] like Figure 1 and 2 As shown, this embodiment provides a stamping equipment with multiple stamping positions, which includes a die module and a feeding module 3.

[0098] The mold module includes a lower mold 1 and an upper mold 2 that can be brought close together or opened. The top of the lower mold 1 has a material passage 11 through it. The material passage 11 is provided with several stamping positions 12. The stamping positions 12 are used to place the product raw material 61 to be stamped. The upper mold 2 is provided with a punch 21.

[0099] The feeding module 3 is located next to one of the openings of the feed channel 11. The feeding module 3 is used to continuously push the product raw material 61 to be stamped into the stamping position 12 in the feed channel 11 for the punch 21 to stamp and form the stamped material 62. The feeding module 3 can be a conventional vibratory feeder or other mechanism that can push the product raw material 61 into the feed channel 11.

[0100] The following is a description of the operation of the stamping equipment described in this embodiment.

[0101] When a large batch of raw material 61 needs to be pressed and plastically molded, the feeding module 3 pushes the raw material 61 into the feed channel 11. At this time, the raw material 61 is located in the stamping position 12, thus completing the feeding. Subsequently, the lower die group 1 and the upper die group 2 move closer together, causing the punch 21 to stamp the raw material 61 in the stamping position 12 to form the stamped material 62. After that, the lower die group 1 and the upper die group 2 open up to each other. Then, the feeding module 3 pushes another raw material 61 into the feed channel 11. At this time, the other raw material 61 is located in the stamping position 12. At the same time, the other raw material 61 pushes the stamped material 62 in the stamping position 12 out from another opening of the feed channel 11, thus completing the unloading.

The discharge module 4 is used to pull the punched material 62 out from the other opening of the feed channel 11. The discharge module 4 can be a horizontally movable clamp, suction cup, or other module that can pull the punched material 62 out from the other opening of the feed channel 11.

[0107] The following is a description of the operation of the stamping equipment described in this embodiment.

[0108] When a large batch of product raw materials 61 needs to be pressed and plastically molded, the feeding module 3 pushes the product raw materials 61 into the feed channel 11. At this time, the product raw materials 61 are located in the stamping position 12, thus completing the feeding. Subsequently, the lower die group 1 and the upper die group 2 move closer to each other, so that the punch 21 stamps the product raw materials 61 in the stamping position 12 to form the stamped material 62. After that, the lower die group 1 and the upper die group 2 open up to each other. Then, the feeding module 3 pushes another product raw material 61 into the feed channel 11. At this time, the other product raw material 61 pushes the stamped material 62 in the stamping position 12 to the next stamping position 12 adjacent to the stamping position 12 for the punch 21 to stamp a second time. The stamped material 62 in the last stamping position 12 is pushed out from another opening of the feed channel 11 by the stamped material 62 in the previous stamping position 12 adjacent to the stamping position 12, thus completing the unloading.

[0109] The following is Example 3

[0110] like Figure 1 and 2 As shown, this embodiment provides a stamping equipment with multiple stamping positions, which includes a mold module, a feeding module 3 and an output module 4.

[0111] The mold module includes a lower mold 1 and an upper mold 2 that can be brought close together or opened. The top of the lower mold 1 has a material passage 11 through it. The material passage 11 is provided with a number of stamping positions 12. The stamping positions 12 are used to place the product raw material 61 to be stamped or the stamped material 62. Both sides of the stamping position 12 are connected to another adjacent stamping position 12. The upper mold 2 is provided with a punch 21.

[0112] The feeding module 3 is located next to one of the openings of the feed channel 11. The feeding module 3 is used to continuously push the product raw material 61 to be stamped into the stamping position 12 in the feed channel 11 for the punch 21 to stamp and form the stamped material 62. The feeding module 3 is a front winding machine, and the discharge module 4 winds up the raw material steel strip 6. The product raw material 61 is a part of the raw material steel strip 6.

[0113] The discharge module 4 is located next to another opening of the feed channel 11. The discharge module 4 is used to pull the punched material 62 out from the other opening of the feed channel 11. The discharge module 4 is a rear winding machine. The raw material steel strip 6 is pulled out from the front winding machine, passes through the feed channel 11 and is wound onto the discharge module 4. The discharge module 4 is used to pull and wind up the raw material steel strip 6.

[0114] The following is a description of the operation of the stamping equipment described in this embodiment.

[0115] When a large batch of product raw materials 61 needs to be pressed and plastically molded, the feeding module 3 controls the unwinding of the raw material steel strip 6, while the discharging module 4 rewinds the raw material steel strip 6, so that the product raw materials 61 located on the raw material steel strip 6 are fed into the material passage 11. At this time, the product raw materials 61 are located in the stamping position 12, thus completing the feeding. Afterwards, the lower die group 1 and the upper die group 2 move closer to each other, so that the punch 21 stamps the product raw materials 61 in the stamping position 12 to form the stamped material 62; afterwards, the lower die group 1 and the upper die group 2 open to each other. Subsequently, the feeding module 3 continues to control the unwinding of the raw material steel strip 6, while the discharging module 4 rewinds the raw material steel strip 6, thereby sending another product material 61 from the raw material steel strip 6 into the material passage 11. At this time, the raw material steel strip 6 drives the punched material 62 to move to the next punching position 12 adjacent to the punching position 12 for a second punching by the punch 21. At the same time, the raw material steel strip 6 drives the punched material 62 located in the last punching position 12 to be sent out from another opening of the material passage 11, thereby completing the unloading.

[0116] The following is Example 4

[0117] like Figure 1 and 2 As shown, this embodiment provides a stamping equipment with multiple stamping positions, which includes a die module, a feeding module 3, a discharge module 4, and a knock-down module 5.

[0118] The mold assembly includes a lower mold assembly 1 and an upper mold assembly 2 that can be brought closer together or opened. A feed channel 11 extends through the top of the lower mold assembly 1, and several stamping positions 12 are arranged along the feed channel 11. Each stamping position 12 is used to hold the product raw material 61 to be stamped or the stamped post-stamping material 62. Each stamping position 12 is connected to another adjacent stamping position 12 on both sides. Each stamping position 12 is equipped with a lower elastic component 13, which pushes a lower top block 14, which can be embedded within the lower mold assembly 1. The upper mold assembly 2 is equipped with a punch 21. The upper mold assembly 2 is equipped with a first elastic component 22, which pushes a movable stop plate 23. The punch 21 passes through the stop plate 23. When the punch 21 stamps the product raw material 61 or the stamped post-stamping material 62, the first elastic component pushes the stop plate 23 to conform to the product raw material 61 and the stamped post-stamping material 62. The stop plate 23 is provided with a second elastic component 24, which pushes an outward push block 25, which can be embedded in the stop plate 23.

[0119] The feeding module 3 is located next to one of the openings of the feed channel 11. The feeding module 3 is used to continuously push the product raw material 61 to be stamped into the stamping position 12 in the feed channel 11 for the punch 21 to stamp and form the stamped material 62. The feeding module 3 is a front winding machine, and the discharge module 4 winds up the raw material steel strip 6. The product raw material 61 is one part of the raw material steel strip 6.

[0120] The discharge module 4 is located next to another opening of the feed channel 11. The discharge module 4 is used to pull the punched material 62 out from the other opening of the feed channel 11. The discharge module 4 is a rear winding machine. The raw material steel strip 6 is pulled out from the front winding machine, passes through the feed channel 11 and is wound onto the discharge module 4. The discharge module 4 is used to pull and wind up the raw material steel strip 6. The lower top block 14 is a roller that contacts the raw material steel strip 6, the product raw material 61 or the punched material 62.

[0121] The knock-off module 5 is located between the other opening of the feed channel 11 and the discharge module 4. The knock-off module 5 is used to knock the punched material 62 pulled out from the other opening of the feed channel 11 away from the raw material steel strip 6. The knock-off module 5 can be a mechanical mechanism such as a cylinder or electric cylinder that can knock the punched material 62 away from the raw material steel strip 6.

[0122] The following is a description of the operation of the stamping equipment described in this embodiment.

[0123] When a large batch of product raw materials 61 needs to be pressed and plastically molded, the feeding module 3 controls the unwinding of the raw material steel strip 6, while the discharging module 4 rewinds the raw material steel strip 6, so that the product raw materials 61 located on the raw material steel strip 6 are fed into the material passage 11. At this time, the product raw materials 61 are located in the stamping position 12, thus completing the feeding. Afterwards, the lower die group 1 and the upper die group 2 move closer to each other, so that the punch 21 stamps the product raw materials 61 in the stamping position 12 to form the stamped material 62; afterwards, the lower die group 1 and the upper die group 2 open to each other. Subsequently, the feeding module 3 continues to control the unwinding of the raw material steel strip 6, while the discharging module 4 rewinds the raw material steel strip 6, thereby sending another product material 61 from the raw material steel strip 6 into the material passage 11. At this time, the raw material steel strip 6 drives the punched material 62 to move to the next punching position 12 adjacent to the punching position 12 for a second punching by the punch 21. At the same time, the raw material steel strip 6 drives the punched material 62 located in the last punching position 12 to be sent out from another opening of the material passage 11, thereby completing the unloading.

[0124] When the punched material 62 is pulled out from the other opening of the feed channel 11, the knocking module 5 knocks the punched material 62 pulled out from the other opening of the feed channel 11 off the raw material steel strip 6.

[0125] After the lower module 1 and the upper module 2 come together, the product raw material 61 or the stamped material 62 is pushed into the lower module 1 by the pressing force generated by the lower module 1 and the upper module 2 coming together, and the outer push block 25 is pushed into the stop plate. At the same time, the first elastic component 22 pushes the stop plate 23 to contact the product raw material 61 or the stamped material 62 to fix the product raw material 61 or the stamped material 62.

[0126] After the punch 21 completes the stamping of the product raw material 61 or the stamped material 62, and the lower die 1 and the upper die 2 open up to each other, the lower elastic component 13 pushes the lower top block 14 to lift the stamped material 62 from the stamping position 12, thereby preventing the stamped material 62 from sticking to the stamping position 12 and being unable to move. At the same time, the second elastic component pushes the outer push block 25 to push the stamped material 62 away from the stop plate 23, thereby preventing the stamped material 62 from sticking to the stop plate 23 and being unable to move.

[0127] The following is Example 5

[0128] like Figure 3 As shown, this embodiment provides a stamping device with multiple stamping positions, which includes all the features of the stamping device described in Embodiment 3 or 4. Furthermore, it also includes a positioning system.

[0129] An information strip 63 is provided on the side of the raw material steel strip 6, extending from one end to the other. The surface of the information strip 63 is coated with a magnetic coating 64, the magnetic field strength and poles of which change irregularly and continuously. Magnetometers 7 for contacting the information strip 63 are distributed at different positions on the feed channel 11. The first magnetometer 71 is located at the beginning of the feed channel 11.

[0130] The following is a description of the operation of the stamping equipment described in this embodiment.

[0131] When the raw material steel strip 6 moves within the feed channel 11, the first magnetic sensor 71 acquires the changes in the magnetic field strength and magnetic poles of the information strip 63 in advance and transmits them to the positioning system. The positioning system converts the changes in the magnetic field strength and magnetic poles sensed by the first magnetic sensor 71 into a continuously changing waveform for reference.

[0132] The magnetic sensor 7 acquires the changes in the magnetic field strength and magnetic poles of the information strip 63 and transmits them to the positioning system for comparison. At this time, the positioning system converts the changes in the magnetic field strength and magnetic poles acquired by the magnetic sensor 7 into a continuously changing waveform for comparison. When the continuously changing waveform of one of the magnetic sensors 7 matches a certain segment of the continuously changing waveform used for reference, the position of each part of the raw material steel strip 6 is determined, thereby locating each part of the raw material steel strip 6. At the same time, the moving speed of the raw material steel strip 6 in the feed channel 11 is determined based on the time from the appearance of the continuously changing waveform used for reference to the matching of the continuously changing waveform.

[0133] The following is Example 6

[0134] like Figure 3 As shown, this embodiment provides a stamping device with multiple stamping positions, which includes all the features of the stamping device described in Embodiment 3 or 4. It also includes a positioning system, a coil module 72, and a current controller.

[0135] An information strip 63 is provided on the side of the raw material steel strip 6, extending from one end to the other. The surface of the information strip 63 is coated with a magnetic coating 64, the magnetic field strength and magnetic poles of which change irregularly and continuously. The magnetic coating 64 contains a layer of magnetic powder bonded together with an adhesive. Magnetometers 7 are distributed at different positions on the feed channel 11 to contact the information strip 63.

[0136] The coil module 72 is located between the feed channel 11 and the feeding module 3. The coil module 72 is used to contact the information tape 63 and is connected to the current controller via electrical signals.

[0137] The following is a description of the operation of the stamping equipment described in this embodiment.

[0138] As the raw material steel strip 6 moves within the feed channel 11, the information strip 63 slides past the coil module 72. At this time, the current controller supplies different currents to the coil module 72, causing the coil module 72 to adjust and arrange the magnetic field changes of the magnetic coating 64, thereby editing the positioning information for different parts of the raw material steel strip 6. Furthermore, the positioning system converts the different currents supplied to the coil module 72 by the current controller into another continuously changing waveform for reference. When the continuously changing waveform observed by one of the magnetic sensors 7 matches a segment of the other continuously changing waveform used as a reference, the position of each part of the raw material steel strip 6 is determined. Simultaneously, the moving speed of the raw material steel strip 6 within the feed channel 11 is determined based on the time from the appearance of the other continuously changing waveform to its match with the compared continuously changing waveform.

[0139] The following is Example 7

[0140] This embodiment provides a stamping device with multiple stamping positions 12, which includes a feeding module 3, a die module, an output module 4, and a knock-down module 5.

[0141] The feeding module 3 winds up the raw material steel strip 6, and the part on the raw material steel strip 6 is the product raw material 61.

[0142] The mold module has a material passage 11 running through it. The material passage 11 is provided with several stamping positions 12, which are used to place the product raw material 61 to be stamped.

[0143] The raw material steel strip 6 is pulled out from the feeding module 3, passes through the material passage 11 and is wound onto the discharge module 4.

[0144] The knockdown module 5 is located between the material passage 11 and the discharge module 4.

[0145] The following is a description of the operation of the stamping equipment described in this embodiment.

[0146] When the product raw material 61 is stamped to form the stamped material 62, the raw material steel strip 6 can be pulled and wound up by the discharge module 4 so that each part of the raw material steel strip 6 passes through the feed channel 11, thereby continuously and orderly feeding several product raw materials 61 into each stamping position 12 for the feeding module 3 to stamp to form the stamped material 62, thus completing the feeding action.

[0147] After the product raw material 61 is stamped, the discharge module 4 pulls and rewinds the raw material steel strip 6. The stamped material 62 also moves out of the feed channel 11 along with the movement of the raw material steel strip 6. At this time, the knocking module 5 knocks the stamped material 62 off the raw material steel strip 6 to complete the unloading action.
