Description

Technical Field

[0001] The present invention belongs to the technical field of stamping dies, and in particular relates to a stamping device with multiple stamping positions. Background Art

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

[0003] In conventional stamping equipment, the product raw material is mainly transported into the mold by a transport mechanism (a clamp or suction cup that can be moved along the xyz axis) or an operator. After the mold plastically forms the product raw material, the transport mechanism or the operator moves the plastically formed product out of the mold, and finally another product raw material is transported to the mold for plastic forming. As a result, loading and unloading are cumbersome and inefficient.

[0004] In addition, since the traditional conveying mechanism needs to use the xyz-axis drive module to drive the clamp or suction cup to move between the lower module and the upper module in order to transport the product raw materials to the pressing position and remove the punched materials from the pressing position, the movement range of the xyz-axis drive module needs to be larger than the lower module and the upper module, resulting in high equipment costs and large equipment space.

[0005] Finally, since the lower module and the upper module need to open and close when working, the transport mechanism needs to use the xyz-axis drive module to drive the clamp or suction cup to move between the lower module and the upper module, which can easily cause the opening and closing movement of the lower module and the upper module to conflict with the movement of the clamp or suction cup. Summary of the Invention

[0006] The purpose of the present 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: The feeding module reels the raw steel strip, and the part on the raw steel strip is the product raw material; A mold module is provided with a material channel running through the mold module. The material channel is provided with a plurality of punching positions, and the punching positions are used to place the raw materials of the products to be punched; Discharging module: the raw steel strip is pulled out from the feeding module, passes through the feeding channel and is wound on the discharging module; Shooting down module, the shooting down module is located between the material channel and the discharging module; The raw steel strip is pulled and rolled up by the discharging module, so that various parts of the raw steel strip pass through the material channel, so as to continuously feed the product raw materials on the raw steel strip into the stamping position for the die module to stamp to form the punched material. At the same time, the punched material is also moved out of the material channel as the raw steel strip moves. At this time, the knocking down module knocks the punched material off the raw steel strip to complete the stripping.

[0008] Based on the above technical solution, the present invention achieves the following beneficial effects: 1. Since the raw steel strip is pulled out from the feeding module, passes through the material channel and is wound on the discharging module, when the product raw material is stamped to form the post-punching material, it is only necessary to pull and wind the raw steel strip through the discharging module, so that various parts of the raw steel strip can pass through the material channel, and a number of product raw materials can be continuously and orderly fed into various stamping positions for the said die module to stamp to form the post-punching material, thereby completing the feeding action. Therefore, it is no longer necessary to move the product raw materials from different stamping positions through a handling mechanism or an operator, thereby improving production efficiency and simplifying the production process; 2. After the product raw materials are stamped, the discharging module pulls and reels the raw steel strip. The punched material also moves out of the material channel as the raw steel strip moves. At this time, the knocking module knocks the punched material off the raw steel strip to complete the unloading action, thereby further improving production efficiency and simplifying the production process. 3. Since there is no need to set up a transport mechanism between each stamping position and at the loading and unloading ends, it is possible to load the product raw materials, send the stamped materials to each stamping position, and unload the stamped materials, thereby further reducing the manufacturing cost of the equipment and the size of the equipment.

[0009] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0010] In some embodiments, the mold module comprises: Lower die set, the material channel runs through the top of the lower die set; The upper die set is provided with a punch, and the upper die set can be moved closer to or opened with the lower die set so that the punch can punch the product raw material located in the punching position to form the punched material.

[0011] Based on the above technical solution, the mold assembly and the lower mold assembly are opened and closed to achieve stamping of the product raw materials located in the stamping position.

[0012] In some embodiments, if different modes of stamping are required for the product raw materials, traditional stamping equipment, after stamping the product raw materials into stamped materials, generally needs to transport the stamped materials to another stamping equipment for secondary stamping through a transport mechanism (a clamp or suction cup movable in the xyz axis) or an operator, resulting in low production efficiency and complicated procedures; therefore, the present invention further provides the following technical solutions.

[0013] The present invention further provides a plurality of punching positions arranged in an arrangement on the material passage, and the punching positions are used to place product raw materials to be punched or punched materials. Both sides of the punching position are connected to another adjacent punching position. When the product raw materials are pushed into the material passage, the product raw materials will push the punched material in the punching position to the next punching position adjacent to the punching position for secondary punching, or push it out from another opening of the material passage.

[0014] Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. When the feeding module pushes another product raw material into the material channel, the other product raw material pushes the punched material in the punching position to the next punching position adjacent to the punching position for secondary punching, and the punched material in the last punching position is pushed out from the other opening of the material channel by the punched material in the previous punching position adjacent to the punching position, thus completing the material unloading. Therefore, when different modes of punching are required for the raw materials, there is no need to move the punched materials from different punching positions through the handling mechanism or the operator, thereby improving production efficiency and simplifying the production process; 2. Since there is no need to set up a transport mechanism between each stamping position and at the loading and unloading ends, it is possible to load the product raw materials, send the stamped materials to each stamping position, and unload the stamped materials, thereby further reducing the manufacturing cost of the equipment and the size of the equipment.

[0015] In some embodiments, the punching position is provided with a lower elastic component, and the lower elastic component pushes a lower ejector block; When the lower die set and the upper die set are brought closer to each other, the product raw material or the punched material pushes the lower ejector block into the lower die set, and when the lower die set and the upper die set are opened to each other, the lower elastic component pushes the lower ejector block to lift the punched material from the punching position.

[0016] Based on the technical solution, the present invention further achieves the following beneficial effects: 1. After the lower die set and the upper die set are brought close to each other, the product raw material or the punched material is pushed into the lower die set by the pressing force generated by the lower die set and the upper die set. When the punch is punching the product raw material or the punched material, the lower ejector block is prevented from causing pressure damage to the product raw material or the punched material. 2. After the punch completes punching the product raw material or the post-punching material, and the lower die set and the upper die set open to each other, the lower elastic component pushes the lower ejector block to lift the post-punching material from the punching position, thereby preventing the post-punching material from sticking to the punching position and being unable to move.

[0017] In some embodiments, the lower top block is a roller that contacts the raw steel strip, product raw material, or punched material; Based on the above technical solution, when the raw steel strip, product raw material or punched material moves in the material channel, the resistance generated by the friction between the lower top block and the raw steel strip, product raw material or punched material can be reduced, thereby protecting the product raw material and punched material.

[0018] In some embodiments, an information strip is provided on the side of the steel strip, extending from one end of the steel strip to the other end of the steel strip. A magnetic coating is provided on the surface of the information strip, and the magnetic field strength and magnetic polarity of the magnetic coating change continuously and irregularly. Magnetic sensors for contacting the information strip are distributed at different positions of the material channel. When the steel strip moves in the material channel, the magnetic sensor continuously senses the magnetic field strength and magnetic poles on the information strip, and locates all parts of the steel strip based on the changes in the magnetic field strength and magnetic poles.

[0019] Based on the technical solution, the present invention further achieves the following beneficial effects: 1. It can realize positioning of all parts of the steel belt without blind spots; 2. Compared with the traditional method of arranging several storage units into information codes (binary or digital codes), the information storage capacity is increased.

[0020] In some embodiments, the stamping equipment provided by the present invention also includes: a positioning system, a first magnetic sensor is provided at the head end of the material channel, 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.

[0021] Based on the technical solution, the present invention further achieves the following beneficial effects: 1. When the continuously changing waveform of one of the magnetic sensors matches a certain section of the continuously changing waveform used for reference, the position of each part of the steel strip is determined, thereby achieving accurate and efficient positioning of each part of the steel strip; 2. The moving speed of the steel strip in the material channel 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 used for comparison, so as to facilitate monitoring the performance status of the equipment and optimize the production plan and capacity expectation.

[0022] In some embodiments, the stamping equipment provided by the present invention also includes a current controller and a coil module. The coil module is located between the material channel 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.

[0023] Based on the technical solution, the present invention further achieves the following beneficial effects: 1. When the information tape slides over the coil module, the current controller transmits different currents to the coil module, so that the coil module arranges the magnetic field of the magnetic coating, thereby editing the positioning information of different parts of the steel tape; 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 section of the other continuously changing waveform for reference, the position of each part of the steel strip is determined, thereby achieving accurate and efficient positioning of each part of the steel strip.

[0024] 3. The moving speed of the steel strip in the material channel is determined based on the time from the appearance of another continuously changing waveform used for reference to the matching of the continuously changing waveform, thereby facilitating the monitoring of the performance status of the equipment and optimizing the production plan and capacity expectations.

[0025] In some embodiments, the upper die set is provided with a first elastic component, which pushes a stop plate that is movable and retractable. When the punch passes through the stop plate and the punch hits the product raw material or the punched material, the first elastic component pushes the stop plate to fit the product raw material or the punched material. Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. The stop plate can prevent the lower die and upper die from being over-closed, which may cause damage to the product raw materials or punched materials; 2. When the punch punches the product raw material or the punched material, the first elastic component pushes the stop plate to contact the product raw material or the punched material, thereby fixing the product raw material or the punched material, thereby preventing the product raw material or the punched material from shifting; 3. When the lower die and upper die are over-closed, the closing force can be buffered, thereby protecting the lower die, upper die, product raw materials and post-punching materials.

[0026] In some embodiments, the stop plate is provided with a second elastic component, and the second elastic component pushes an outward push block; When the lower die set and the upper die set are brought closer to each other, the product raw material or the punched material pushes the push block into the stop plate, and when the lower die set and the upper die set are opened to each other, the second elastic component pushes the push block out of the stop plate to push the punched material away from the stop plate.

[0027] Based on the technical solution, the present invention further achieves the following beneficial effects: 1. After the lower die set and the upper die set are brought close to each other, the product raw material or the punched material is pushed into the stopper by the pressing force generated by the lower die set and the upper die set. When the punch is punching the product raw material or the punched material, the push-out block is prevented from causing pressure damage to the product raw material or the punched material. 2. After the punch completes punching the product raw material or the post-punching material, and the lower die set and the upper die set open to each other, the second elastic group pushes the push block to push the post-punching material away from the stop plate, thereby preventing the post-punching material from sticking to the stop plate and being unable to move.

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear, the following description is given with reference to the accompanying drawings.

[0032] like Figures 1 to 3 As shown, this embodiment provides a stamping device with multiple stamping positions, which includes: The mold module includes a lower mold assembly 1 and an upper mold assembly 2 that can be moved closer or opened to each other. The top of the lower mold assembly 1 is penetrated by a material channel 11, and the material channel 11 is provided with a plurality of punching positions 12. The punching positions 12 are used to place the product raw material 61 to be punched. The upper mold assembly 2 is provided with a punch 21; The feeding module 3 is located next to one of the openings of the material channel 11. The feeding module 3 is used to continuously push the product raw material 61 to be punched into the punching position 12 in the material channel 11 for the punch 21 to punch and form the punched material 62. When the product raw material 61 is pushed into the material channel 11, the product raw material 61 will push the punched material 62 in the punching position 12 out of the other opening of the material channel 11.

[0033] When a large number of product raw materials 61 need to be pressed and plastically formed, the feeding module 3 pushes the product raw material 61 into the material channel 11. At this time, the product raw material 61 is located in the punching position 12, thereby completing the loading. When the lower module 1 and the upper module 2 move closer to each other, so that the punch 21 punches the product raw material 61 in the punching position 12 to form the punched material 62, the lower module 1 and the upper module 2 open to each other, and then the feeding module 3 pushes another product raw material 61 into the material channel 11. At this time, the other product raw material 61 is located in the punching position 12. At the same time, the other product raw material 61 pushes the punched material 62 in the punching position 12 out of the other opening of the material channel 11, thereby completing the unloading. Therefore, there is no need to use a conveying mechanism or an operator to move the product raw material 61 and the punched material 62 between the lower module 1 and the upper module 2 to achieve loading and unloading, thereby improving the convenience and efficiency of loading and unloading.

[0034] Because the stamping equipment does not require a transport mechanism, it can also achieve loading and unloading, thereby reducing the equipment's manufacturing costs and space usage. In addition, because the raw material punches or punched material 62 do not need to be moved back and forth during loading and unloading, the loading and unloading steps are simplified, thereby improving loading and unloading efficiency. In addition, because the stamping equipment does not require a transport mechanism, the possibility of collision with the opening and closing movement of the lower die assembly 1 and the upper die assembly 2 can be effectively avoided during loading and unloading.

[0035] In some embodiments, the material passage 11 is arranged with a plurality of punching positions 12, and the punching positions 12 are used to place the product raw material 61 to be punched or the punched material 62 that has been punched. Both sides of the punching position 12 are connected to another adjacent punching position 12. When the product raw material 61 is pushed into the material passage 11, the product raw material 61 will push the punched material 62 in the punching position 12 to the next punching position 12 adjacent to the punching position 12 for secondary punching by the punch 21, or push it out from another opening of the material passage 11.

[0036] When the feeding module 3 pushes another product raw material 61 into the material channel 11, the other product raw material 61 pushes the punched material 62 in the punching position 12 to the next punching position 12 adjacent to the punching position 12 for secondary punching by the punch 21, and the punched material 62 in the punching position 12 at the end is pushed out from the other opening of the material channel 11 by the punched material 62 in the previous punching position 12 adjacent to the punching position 12, thereby completing the unloading. Therefore, when different modes of punching of the raw materials are required, there is no need to move the punched material 62 from different punching positions 12 through a conveying mechanism or an operator, thereby improving production efficiency and simplifying the production process.

[0037] Since there is no need to set up a conveying mechanism between each stamping position 12, and at the loading and unloading ends, the product raw material 61 can be loaded, the punched material 62 can be delivered to each stamping position 12, and the punched material 62 can be unloaded, thereby further reducing the manufacturing cost of the equipment and the volume of the equipment.

[0038] In some embodiments, the stamping equipment also includes a discharge module 4, which is located next to the other opening of the material channel 11. The discharge module 4 is used to pull the punched material 62 out from the other opening of the material channel 11, thereby preventing the punched material 62 from getting stuck in the other opening of the material channel 11, thereby improving the stability of the punched material 62.

[0039] In some embodiments, the feeding module 3 is a front winder, the discharging module 4 winds up the raw steel strip 6, the product raw material 61 is one part of the raw steel strip 6, the discharging module 4 is a rear winder, the raw steel strip 6 is pulled out from the feeding module 3, passes through the material channel 11 and is wound on the discharging module 4, and the discharging module 4 is used to pull and wind up the raw steel strip 6.

[0040] Therefore, the unwinding speed of the raw steel strip 6 is controlled by the feeding module 3, and the raw steel strip 6 is wound by the discharging module 4, so that the product raw material 61 can be moved horizontally and stably and smoothly into the material channel 11, and the punched material 62 can be delivered to each punching position 12 and unloaded.

[0041] In some embodiments, a knockdown module 5 is provided between the other opening of the feed channel 11 and the discharge module 4. The knockdown 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 steel strip 6. After the punched material 62 is pulled out from the other opening of the feed channel 11, it can be taken out of the raw steel strip 6, thereby facilitating the centralized collection and management of the punched material 62 that has completed the stamping.

[0042] In some embodiments, the punching station 12 is provided with a lower elastic component 13, which pushes a lower ejector block 14. When the lower die 1 and the upper die 2 are brought closer together, the product raw material 61 or the punched material 62 pushes the lower ejector block 14 into the lower die 1. When the lower die 1 and the upper die 2 are opened apart, the lower elastic component 13 pushes the lower ejector block 14 to lift the punched material 62 from the punching station 12.

[0043] After the lower die group 1 and the upper die group 2 move closer to each other, the product raw material 61 or the punched material 62 is pushed into the lower die group 1 by the pressing force generated by the lower die group 1 and the upper die group 2 moving closer to each other, so that when the punch 21 punches the product raw material 61 or the punched material 62, the lower top block 14 is prevented from causing pressure damage to the product raw material 61 or the punched material 62.

[0044] After the punch 21 completes punching the product raw material 61 or the punched material 62 and the lower die set 1 and the upper die set 2 open to each other, the lower elastic component 13 pushes the lower ejector block 14 to lift the punched material 62 from the punching position 12, thereby preventing the punched material 62 from sticking to the punching position 12 and being unable to move.

[0045] In some embodiments, the lower top block 14 is a roller in contact with the raw steel strip 6, the product raw material 61, or the punched material 62. This allows the raw steel strip 6, the product raw material 61, or the punched material 62 to move in the material passage 11 while reducing the resistance generated by the friction between the lower top block 14 and the raw steel strip 6, the product raw material 61, or the punched material 62, thereby protecting the product raw material 61 and the punched material 62.

[0046] In some embodiments, an information belt 63 is provided on the side of the steel belt, and the information belt 63 extends from one end of the steel belt to the other end of the steel belt. A magnetic coating 64 is provided on the surface of the information belt 63. The magnetic field strength and magnetic pole of the magnetic coating 64 change irregularly and continuously. Magnetic sensors 7 for contacting the information belt 63 are distributed at different positions of the material channel 11.

[0047] When the steel strip moves in the material channel 11, the magnetic sensor 7 continuously and uninterruptedly senses the magnetic field strength and magnetic poles on the information strip 63, so as to locate and register processing information of all parts of the steel strip based on the changes in the magnetic field strength and magnetic poles.

[0048] Therefore, it is possible to realize the positioning and processing information registration of all parts of the steel strip without blind spots; in addition, compared with the traditional arrangement of several storage units into information codes (binary or digital codes), the information storage capacity is increased.

[0049] In some embodiments, the stamping equipment also includes a positioning system. A first magnetic sensor 7 is provided at the head end of the material transfer channel 11. The first magnetic sensor 7 is used to pre-acquire the magnetic field strength and magnetic pole changes of the information band 63 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 7 into a continuously changing waveform for reference. The magnetic sensor 7 obtains the magnetic field strength and magnetic pole changes of the information band 63 and transmits them to the positioning system for comparison. The positioning system converts the magnetic field strength and magnetic pole changes obtained by the magnetic sensor 7 into a continuously changing waveform for comparison.

[0050] When the continuously varying waveform displayed by one of the magnetic sensors 7 matches a certain segment of the reference continuously varying waveform, the position of each part of the steel strip is determined, thereby achieving accurate and efficient positioning of each part of the steel strip. In addition, the speed of the steel strip in the material channel 11 is determined based on the duration between the appearance of the reference continuously varying waveform and the match of the continuously varying waveform, thereby facilitating monitoring of equipment performance and optimizing production plans and capacity expectations.

[0051] In some embodiments, the stamping equipment also includes a current controller and a coil module 72. The coil module 72 is located between the material channel 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 countless ferromagnetic nanoparticles (such as barium ferrite BFe).

[0052] When the information tape 63 slides over the coil module 72, the current controller transmits different currents to the coil module 72, causing the coil module 72 to generate a high magnetic field to arrange the countless ferromagnetic nanoparticles in the magnetic powder layer of the magnetic coating 64, change the magnetic field of the magnetic coating 64, and thus edit the positioning information of different parts of the steel tape.

[0053] According to the current controller, different currents are supplied to the coil module 72, which are converted into another reference continuously changing waveform. When the compared continuously changing waveform of one of the magnetic sensors 7 matches a certain section of the continuously changing waveform of the other reference, the positions of various parts of the steel strip are judged, thereby achieving accurate and efficient positioning of various parts of the steel strip. In addition, the moving speed of the steel strip in the material channel 11 is judged based on the length of time from the appearance of another reference continuously changing waveform to the matching of the compared continuously changing waveform, thereby facilitating monitoring of the performance status of the equipment and optimizing production plans and capacity expectations.

[0054] In some embodiments, the upper die set 2 is provided with a first elastic component 22, and the first elastic component 22 pushes a stop plate 23 that is movable and can be raised and lowered. When the punch 21 passes through the stop plate 23 and the punch 21 hits the product raw material 61 or the punched material 62, the first elastic component pushes the stop plate 23 to fit the product raw material 61 and the punched material 62. Therefore, the stop plate 23 can prevent the lower die set 1 and the upper die set 2 from being over-closed and causing 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 the product raw material 61 or the punched material 62, the product raw material 61 or the punched material 62 is fixed, thereby preventing the product raw material 61 or the punched material 62 from shifting.

[0055] When the lower die set 1 and the upper die set 2 are excessively closed, the closing force can be buffered, thereby protecting the lower die set 1 , the upper die set 2 , the product raw material 61 and the punched material 62 .

[0056] In some embodiments, the stop plate 23 is provided with a second elastic component 24 , and the second elastic component 24 pushes an outward pushing block 25 .

[0057] When the lower die set 1 and the upper die set 2 move closer to each other, the product raw material 61 or the punched material 62 pushes the push-out block 25 into the stop plate 23 . When the lower die set 1 and the upper die set 2 move away from each other, the second elastic component 24 pushes the push-out block 25 out of the stop plate 23 to push the punched material 62 away from the stop plate 23 .

[0058] After the lower die group 1 and the upper die group 2 move closer to each other, the product raw material 61 or the punched material 62 is pushed into the stop block by the pressing force generated by the lower die group 1 and the upper die group 2 moving closer to each other, so that when the punch 21 punches the product raw material 61 or the punched material 62, the push-out block 25 is prevented from causing pressure damage to the product raw material 61 or the punched material 62.

[0059] After the punch 21 completes punching the product raw material 61 or the punched material 62 and the lower die set 1 and the upper die set 2 open to each other, the second elastic group pushes the push block 25 to push the punched material 62 away from the stop plate 23, thereby preventing the punched material 62 from sticking to the stop plate 23 and being unable to move.

[0060] In order to further explain the stamping equipment with multiple stamping stations described in this specific embodiment, the following examples are listed.

[0061] The following is Example 1 like Figure 1 and 2 As shown, this embodiment provides a stamping device with multiple stamping positions, which includes a mold module and a feeding module 3.

[0062] The mold module includes a lower mold group 1 and an upper mold group 2 that can be moved closer or opened to each other. The top of the lower mold group 1 is penetrated by a feed channel 11. The feed channel 11 is provided with several punching positions 12. The punching positions 12 are used to place the product raw materials 61 to be punched. The upper mold group 2 is provided with a punch 21.

[0063] The feeding module 3 is located next to one of the openings of the material passage 11. The feeding module 3 is used to continuously push the product raw material 61 to be punched into the punching position 12 in the material passage 11 for the punch 21 to punch and form the punched material 62. The feeding module 3 can be a conventional vibrating plate or other mechanism that can push the product raw material 61 into the material passage 11.

[0064] The following is a working description of the stamping equipment described in this embodiment.

[0065] When a large number of product raw materials 61 need to be pressed and plastically formed, the feeding module 3 pushes the product raw material 61 into the material channel 11. At this time, the product raw material 61 is located in the punching position 12, thereby completing the loading. After that, the lower die 1 and the upper die 2 move closer to each other, so that the punch 21 punches the product raw material 61 in the punching position 12 to form the punched material 62; after that, the lower die 1 and the upper die 2 open to each other. Subsequently, the feeding module 3 pushes another product raw material 61 into the material channel 11. At this time, the other product raw material 61 is located in the punching position 12.

Subsequently, the feeding module 3 continues to control the unwinding of the raw steel strip 6. At the same time, the discharging module 4 rewinds the raw steel strip 6, thereby feeding another product raw material 61 of the raw steel strip 6 into the material channel 11. At this time, the raw steel strip 6 drives the punched material 62 to move to the next punching position 12 adjacent to the punching position 12 for the punch 21 to punch a second time. At the same time, the raw steel strip 6 drives the punched material 62 in the punching position 12 at the end to be sent out from another opening of the material channel 11, thereby completing the unloading.

The punching position 12 is provided with a lower elastic component 13, and the lower elastic component 13 pushes a lower top block 14, and the lower top block 14 can be embedded in the lower die group 1. The upper die group 2 is provided with a punch 21. The upper die group 2 is provided with a first elastic component 22, and the first elastic component 22 pushes a stop plate 23 that can be raised and lowered. The punch 21 passes through the stop plate 23. When the punch 21 hits the product raw material 61 or the punched material 62, the first elastic component pushes the stop plate 23 to fit the product raw material 61 and the punched material 62. The stop plate 23 is provided with a second elastic component 24 . The second elastic component 24 pushes an outward push block 25 . The outward push block 25 can be embedded in the stop plate 23 .

[0080] The feeding module 3 is located next to one of the openings of the material passage 11. The feeding module 3 is used to continuously push the product raw material 61 to be punched into the punching position 12 in the material passage 11 for the punch 21 to punch and form the punched material 62; the feeding module 3 is a front winder, and the discharging module 4 winds up the raw material steel strip 6, and the product raw material 61 is one part of the raw material steel strip 6.

[0081] The discharge module 4 is located next to the other opening of the feed channel 11 and is used to pull the punched material 62 out of the other opening of the feed channel 11. The discharge module 4 is a rear winder. The raw steel strip 6 is pulled from the front winder, passes through the feed channel 11, and is wound on the discharge module 4.

The knockdown module 5 can be a mechanical mechanism such as a pneumatic cylinder or an electric cylinder to realize the separation of the punched material 62 from the raw steel strip 6 by impact.

[0083] The following is a working description of the stamping equipment described in this embodiment.

[0084] When a large number of product raw materials 61 need to be pressed and plastically formed, the feeding module 3 controls the unwinding of the raw steel strip 6, while the discharging module 4 rewinds the raw steel strip 6, so that the product raw materials 61 on the raw steel strip 6 are fed into the material channel 11. At this time, the product raw materials 61 are located in the punching position 12, thus completing the loading. Afterwards, the lower die set 1 and the upper die set 2 move closer to each other, so that the punch 21 punches the product raw materials 61 in the punching position 12 to form the punched material 62; afterward, the lower die set 1 and the upper die set 2 open to each other. Subsequently, the feeding module 3 continues to control the unwinding of the raw steel strip 6. At the same time, the discharging module 4 rewinds the raw steel strip 6, thereby feeding another product raw material 61 of the raw steel strip 6 into the material channel 11. At this time, the raw steel strip 6 drives the punched material 62 to move to the next punching position 12 adjacent to the punching position 12 for the punch 21 to punch a second time. At the same time, the raw steel strip 6 drives the punched material 62 in the punching position 12 at the end to be sent out from another opening of the material channel 11, thereby completing the unloading.

[0085] When the punched material 62 is pulled out from the other opening of the material passage 11 , the knocking-off module 5 knocks the punched material 62 pulled out from the other opening of the material passage 11 away from the raw steel strip 6 .

[0086] After the lower die set 1 and the upper die set 2 move closer to each other, the product raw material 61 or the punched material 62 is pushed into the lower die set 1 and the push block 25 is pushed into the stop block by the pressing force generated by the lower die set 1 and the upper die set 2 moving closer to each other. At the same time, the first elastic component 22 pushes the stop plate 23 to contact the product raw material 61 or the punched material 62 to fix the product raw material 61 or the punched material 62.

[0087] After the punch 21 completes punching the product raw material 61 or the punched material 62, and the lower die set 1 and the upper die set 2 open to each other, the lower elastic component 13 pushes the lower push block 14 to lift the punched material 62 from the punching position 12, thereby preventing the punched material 62 from sticking to the punching position 12 and being unable to move. At the same time, the second elastic group pushes the outward push block 25 to push the punched material 62 away from the stop plate 23, thereby preventing the punched material 62 from sticking to the stop plate 23 and being unable to move.

[0088] The following is Example 5 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. In addition, it also includes a positioning system.

[0089] An information strip 63 is installed on the side of the steel strip, extending from one end to the other. A magnetic coating 64 is applied to the surface of the strip, and the magnetic field strength and polarity of the coating 64 vary continuously and irregularly. Magnetic sensors 7 are located at various locations along the feed channel 11, each designed to contact the information strip 63. The first magnetic sensor 71 is located at the head end of the feed channel 11.

[0090] The following is a working description of the stamping equipment described in this embodiment.

[0091] When the steel strip moves in the material channel 11, the first magnetic sensor 71 pre-acquires the magnetic field strength and magnetic pole changes of the information strip 63 and transmits them to the positioning system. The positioning system converts the magnetic field strength and magnetic pole changes sensed by the first magnetic sensor 71 into a continuously changing waveform for reference.

[0092] The magnetic sensor 7 obtains the magnetic field strength and magnetic pole changes of the information belt 63 and transmits them to the positioning system for comparison. At this time, the positioning system converts the magnetic field strength and magnetic pole changes obtained by the magnetic sensor 7 into a continuously changing waveform for comparison. When the continuously changing waveform of the comparison appearing in one of the magnetic sensors 7 coincides with a certain section of the continuously changing waveform used for reference, the positions of various parts of the steel belt are judged, thereby locating various parts of the steel belt; at the same time, the moving speed of the steel belt in the material channel 11 is judged according to the time length from the continuous changing waveform used for reference to the continuous changing waveform that coincides with the comparison.

[0093] The following is Example 6 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. In addition, it also includes a positioning system, a coil module 72 and a current controller.

[0094] An information strip 63 is installed on the side of the steel strip, extending from one end to the other. A magnetic coating 64 is applied to the surface of the strip. The magnetic field strength and polarity of the coating 64 vary continuously and irregularly. The coating 64 contains a layer of magnetic powder bonded with an adhesive. Magnetic sensors 7 are located at various locations along the feed channel 11, designed to contact the information strip 63.

[0095] 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.

[0096] The following is a working description of the stamping equipment described in this embodiment.

[0097] As the steel strip moves within the feed channel 11, the information strip 63 slides past the coil module 72. At this point, the current controller delivers different currents to the coil module 72, causing it to align the magnetic field of the magnetic coating 64, thereby compiling positioning information for different parts of the steel strip. Furthermore, the positioning system converts the currents delivered by the current controller to another continuously varying reference waveform. When the continuously varying waveform displayed by one of the magnetic sensors 7 matches a certain section of the other continuously varying reference waveform, the position of each part of the steel strip is determined. Simultaneously, the speed of the steel strip within the feed channel 11 is determined based on the duration from the appearance of the other continuously varying reference waveform to the matching continuously varying waveform.

[0098] The following is Example 7 This embodiment provides a stamping device with multiple stamping positions 12, which includes a feeding module 3, a die module, a discharging module 4 and a knocking module 5.

[0099] The feeding module 3 winds up a raw steel strip 6 , and the portion on the raw steel strip 6 is the product raw material 61 .

[0100] A material passage 11 runs through the mold module. The material passage 11 is provided with a plurality of punching positions 12. The punching positions 12 are used to place product raw materials 61 to be punched.

[0101] The raw steel strip 6 is pulled out from the feeding module 3 , passes through the material passage 11 and is wound on the discharging module 4 .

[0102] The knock-down module 5 is located between the material passage 11 and the discharging module 4 .

[0103] The following is a working description of the stamping equipment described in this embodiment.

[0104] When the product raw material 61 is punched to form the post-punching material 62, it is only necessary to pull and roll the raw steel strip 6 through the discharge module 4, so that various parts of the raw steel strip 6 can pass through the material channel 11, and continuously and orderly feed several product raw materials 61 into each stamping position 12 for the feeding module 3 to punch to form the post-punching material 62, thereby completing the loading action.

[0105] After the product raw material 61 is stamped, the discharging module 4 pulls and reels the raw steel strip 6, and the punched material 62 also moves out of the material channel 11 as the raw steel strip 6 moves. At this time, the knocking module 5 knocks the punched material 62 off the raw steel strip 6 to complete the material removal, thereby completing the unloading action.
