Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a stamping die with a blank conveying mechanism. Background Art

[0002] A stamping die is a specialized piece of equipment used to process materials into parts or semi-finished products. This process primarily involves driving a punch inside the die to apply significant pressure to the metal material, causing it to plastically deform and shear, thereby completing the metal processing.

[0003] When producing products with shapes too complex to be formed in one go (e.g., requiring multiple processes like punching, bending, drawing, and flanging), the metal material must be stamped multiple times. Conventional stamping lines typically use a conveyor system to move the metal material one by one to multiple stamping dies for stamping. This results in a cumbersome and inefficient stamping process. Utility Model Content

[0004] The purpose of the utility model is to provide a stamping die with a blank conveying mechanism to solve the technical problems described in the background technology.

[0005] The stamping die with a blank conveying mechanism comprises:

[0006] The lower die and upper die can be moved closer or open to each other, the lower die is provided with a material channel running through its top surface, the material channel is arranged with a number of stamping stations, and the upper die is provided with a punch head for entering the stamping station, a punch and a positioning column;

[0007] The blank conveying mechanism pulls and moves the steel strip raw materials, which enter the material channel and pass through all stamping stations;

[0008] The blank conveying mechanism moves various parts of the steel strip raw material to the stamping station in sequence and in an orderly manner for the stamping head to punch processing. The punching punch is used to enter the first stamping station to punch out positioning holes in the steel strip raw material. Except for the first stamping station, the remaining stamping stations all have corresponding positioning columns, so that when various parts of the steel strip raw material are moved from the first stamping station to the remaining stamping stations, the positioning columns are used to insert into the positioning holes to position various parts of the steel strip raw material and prevent the steel strip raw material from shifting.

[0009] Based on the technical solution, the utility model can achieve the following beneficial effects:

[0010] 1. When multiple stamping of metal raw materials is required, since the steel strip raw material passes through all the stamping stations and the blank conveying mechanism can pull and move the steel strip raw material, the various parts of the steel strip raw material are moved to the stamping stations in sequence and in an orderly manner for the punching head to perform stamping processing, thereby completing multiple stamping of the steel strip raw material. Therefore, compared with conventional stamping lines, it is possible to complete multiple stamping without the need for a conveying mechanism to transport the metal raw material (corresponding to the various parts of the steel strip raw material described in the utility model) back and forth to each stamping die, thereby simplifying the stamping process and improving the stamping efficiency;

[0011] 2. Since the raw material that needs to be stamped multiple times (i.e., a certain part of the steel strip raw material) is pulled by the blank conveying mechanism to realize horizontal movement between multiple stamping stations, a positioning hole is punched out of the steel strip raw material at the first stamping station by a punching punch. At this time, when the part to be stamped of the steel strip raw material is moved to other stamping stations, the positioning column is inserted into the positioning hole to realize the positioning of the part to be stamped of the steel strip raw material, and when the punching head stamps the part to be stamped of the steel strip raw material, the displacement of the part to be stamped of the steel strip raw material can be avoided, thereby improving the stamping accuracy.

[0012] 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.

[0013] In some embodiments, the blank conveying mechanism includes a first winding mechanism and a second winding mechanism, the first winding mechanism winding the steel strip raw material, one end of the steel strip raw material is pulled out from the first winding mechanism into the material channel and passes through all the stamping stations and is finally wound up by the second winding mechanism, and the second winding mechanism is connected to the conveying power module;

[0014] The conveying power module is used to drive the second winding mechanism to wind the steel strip material, so that various parts of the steel strip material are pulled out from the first winding mechanism and moved to the stamping station in sequence and in an orderly manner for stamping processing by the stamping head.

[0015] Based on the technical solution, the utility model can further achieve the following beneficial effects:

[0016] 1. When multiple stamping of metal raw materials is required, the stamping die provided by the utility model only needs to drive the second winding mechanism to reel the steel strip raw material through the conveying power module, so that various parts of the steel strip raw material are pulled out from the first winding mechanism and moved to the stamping station in sequence and orderly for the punching head to stamp, thereby completing multiple stamping of the steel strip raw material. Therefore, compared with conventional stamping lines, it is possible to complete multiple stamping without the need for a transport mechanism to transport the metal raw material (corresponding to the various parts of the steel strip raw material described in the utility model) back and forth to transport each stamping die, thereby simplifying the stamping process and improving the stamping efficiency;

[0017] 2. In conventional stamping lines, multiple independent stamping dies are generally required to complete multiple stamping steps of metal raw materials. However, the stamping die provided by the utility model can complete multiple steps of stamping metal materials with a single stamping die, thereby reducing the equipment cost and space occupation of the stamping line;

[0018] 3. When a part of the steel strip material is transferred to the first stamping station, or when it is transferred from one stamping station to the next stamping station, the part of the steel strip material located in a stamping station is synchronously moved to the next stamping station, or removed from the last stamping station, thereby improving the transfer efficiency and stamping efficiency;

[0019] 4. When the punching head is punching the metal raw material in a certain punching station (i.e. a certain part of the steel strip raw material), the other punching heads will simultaneously punch the metal raw materials in their corresponding punching stations, thereby further improving the stamping efficiency.

[0020] In some embodiments, the positioning post is movably disposed on the upper mold, and the upper mold is provided with a distance sensor located above the positioning post;

[0021] When the upper mold and the lower mold are closed, the distance sensor is used to sense the distance of the positioning pin and determine whether the positioning pin enters the positioning hole to control the closing of the upper mold and the lower mold.

[0022] Based on the above technical solution, during the closing process of the upper and lower molds, if the positioning post does not enter the positioning hole, the steel strip raw material will push the positioning post close to the distance sensor. At this time, the distance sensor sends a signal to stop the closing of the upper and lower molds, thereby protecting the steel strip raw material. At this time, the position of the steel strip raw material (various parts) can be adjusted.

[0023] In some embodiments, a pulley is provided at the bottom end of the positioning column. When the steel strip raw material moves, the upper mold approaches the lower mold, causing the pulley to contact and slide with the steel strip raw material until the pulley slides into the positioning hole to position various parts on the steel strip raw material. When the upper mold and the lower mold are opened, the upper mold drives the positioning column to move out of the positioning hole and controls the distance between the upper mold and the lower mold so that the pulley contacts the surface of the steel strip raw material.

[0024] In some embodiments, the upper mold is provided with a fixed plate that can be raised and lowered and floated. When the upper mold and the lower mold are closed, the fixed plate is pre-contacted with the steel strip raw material to fix the steel strip raw material, so that the punching head can punch various parts of the steel strip raw material more stably.

[0025] In some embodiments, the lower die is provided with a guide hole and a spring, the guide hole is connected to the bottom wall of the stamping station, and an ejector pin connected to the spring is movably provided in the guide hole;

[0026] When the upper and lower molds are closed, the fixed plate pushes the steel strip material to push the ejector pin into the guide hole;

[0027] When the upper and lower molds are opened, the spring pushes the ejector pin to the stamping station to separate the steel strip from the stamping station, thereby preventing the steel strip from sticking to the stamping station and being damaged when the steel strip moves.

[0028] In some embodiments, the first winding mechanism is transmission-connected to an auxiliary power module;

[0029] When the upper and lower dies are closed, the auxiliary power module is used to drive the first winding mechanism to loosen the steel strip material, so that the steel strip material falls to the stamping station due to its own gravity and deformation characteristics;

[0030] When the upper and lower molds are closed, the auxiliary power module is used to drive the first winding mechanism to tighten the steel strip material, so as to separate the steel strip material from the stamping station, thereby avoiding damage caused by friction between the steel strip material and the stamping station during movement.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is an enumerated description with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 3 As shown, this specific embodiment provides a stamping die with a blank conveying mechanism, which includes a lower die 1, an upper die 2 and a blank conveying mechanism.

[0040] The lower die 1 and upper die 2 can be hydraulically driven to move toward or away from each other. The lower die 1 is provided with a material passage 11 extending through its top surface. This passage 11 is used to allow the steel strip 5 to pass through. Several punching stations 12 are arranged along the passage 11. When the steel strip 5 passes through the passage 11, it has already passed through the punching stations 12.

[0041] The upper die 2 is provided with a punching head 21, a punching punch 22 and a positioning column 23. The punching punch 22 is used to enter the first stamping station 12 to punch out a positioning hole 51 for the steel strip raw material 5. Except for the first stamping station 12, the remaining stamping stations 12 all have corresponding positioning columns 23, so that when various parts of the steel strip raw material 5 are moved from the first stamping station 12 to the remaining stamping stations 12, the positioning columns 23 are used to insert into the positioning holes 51 to position various parts of the steel strip raw material 5; the positioning columns 23 are movably arranged on the upper die 2, and the positioning columns 23 can be lifted and lowered by being mounted in the upper die 2 without falling off. The upper die 2 is provided with a distance sensor 24 located above the positioning column 23. The distance sensor 24 is used to measure the distance from the top of the positioning column 23. The distance sensor 24 can be an infrared distance sensor; the bottom end of the positioning column 23 is provided with a pulley 231, which is used to contact the steel strip raw material 5 and slide on the surface of the steel strip raw material 5. Each stamping station 12 has a corresponding punch head 21 that can enter the punch head 21. The punch head 21 is used to stamp the steel strip material 5 in the stamping station 12. The upper die 2 is provided with a floating fixed plate 25 that can be raised and lowered. The fixed plate 25 can be raised and lowered by sliding on the guide pillars. The fixed plate 25 can be mounted on the bottom of the guide pillars by setting a limiter to prevent it from separating from the upper die 2. When the upper die 2 and the lower die 1 are closed, the fixed plate 25 is pre-contacted with the steel strip material 5 by its own weight or the thrust of the spring 14 to fix the steel strip material 5.

[0042] The blank conveying mechanism includes a first winding mechanism 3 and a second winding mechanism 4. The first winding mechanism 3 winds up the steel strip raw material 5. One end of the steel strip raw material 5 is pulled out from the first winding mechanism 3 into the material channel 11 and passes through all the stamping stations 12 and is finally wound up on the second winding mechanism 4. The first winding mechanism 3 is connected to an auxiliary power module, which can be a motor. The second winding mechanism 4 is connected to a conveying power module, which can be a motor. The conveying power module is used to drive the second winding mechanism 4 to reel the steel strip raw material 5, so that various parts of the steel strip raw material 5 are pulled out from the first winding mechanism 3 and moved in sequence and orderly to the stamping station 12 for stamping processing by the punch head 21.

[0043] The following is a working description of the stamping die described in this embodiment.

[0044] One end of the steel strip material 5 is pulled out from the first winding mechanism 3 into the material channel 11 and passes through all the stamping stations 12 and is finally wound up in the second winding mechanism 4. During the stamping process, the upper die 2 and the lower die 1 are closed. At this time, the fixing plate 25 is in contact with the steel strip material 5 in advance to fix the steel strip material 5; then, the punch head 21 punches a certain part of the steel strip material 5 in the stamping station 12. At the same time, the punch 22 punches a positioning hole 51 in the steel strip material 5 in the first stamping station 12. After that, the upper die 2 and the lower die 1 are opened, and the punch head 21 and the punch 22 are away from the steel strip material 5; then, the upper die 2 and the lower die 1 are moved closer to each other so that the pulley 231 is in contact with the steel strip material 5. Afterwards, the conveying power module drives the second winding mechanism 4 to wind the steel strip material 5, so that the steel strip material 5 moves in the material passage 11, thereby driving the portion of the steel strip material 5 in the front stamping station 12 to move to the next stamping station 12 to be stamped, driving the portion of the steel strip material 5 in the last stamping station 12 to move out of the material passage 11 for discharge, and driving the new portion of the steel strip material 5 to enter the first stamping station 12 to be stamped. When the steel strip material 5 moves, the pulley 231 slides on the surface of the steel strip material 5 until the pulley 231 slides into the positioning hole 51. When the distance sensor 24 senses that the positioning column 23 is away, the pulley 231 slides into the positioning hole 51. At this time, the distance sensor 24 sends a signal to close the upper mold 2 and the lower mold 1 for a second pressing; and so on, until the processed part on the steel strip material 5 passes through all the pressing stations.

[0045] When the conveying power module drives the second winding mechanism 4 to wind the steel strip material 5, the auxiliary power module drives the first winding mechanism 3 and the second winding mechanism 4 to work synchronously, so that the steel coil passes through all the stamping stations 12 horizontally.

[0046] You can choose: when the upper mold 2 and the lower mold 1 are closed, the auxiliary power module is used to drive the first winding mechanism 3 to loosen the steel strip raw material 5, so that the steel strip raw material 5 falls and sticks to the stamping station 12 due to its own gravity and deformation characteristics; when the upper mold 2 and the lower mold 1 are closed, the auxiliary power module is used to drive the first winding mechanism 3 to tighten the steel strip raw material 5, so that the steel strip raw material 5 is separated from the stamping station 12, thereby avoiding damage caused by friction between the steel strip raw material 5 and the stamping station 12 when the steel strip raw material 5 moves.

[0047] Example 2

[0048] like Figures 1 to 3 As shown, this specific embodiment provides a stamping die with a blank conveying mechanism, which includes a lower die 1, an upper die 2 and a blank conveying mechanism.

[0049] The lower die 1 and upper die 2 can be moved toward or away from each other by a hydraulic press. The lower die 1 is equipped with a feed channel 11 extending through its top surface. This channel 11 allows the steel strip 5 to pass through. Several punching stations 12 are arranged in a row along the feed channel 11. When the steel strip 5 passes through the feed channel 11, it passes through the punching stations 12. The lower die 1 is equipped with a guide hole 13 and a spring 14. The guide hole 13 is connected to the bottom wall of the punching station 12. An ejector pin 15 connected to the spring 14 is movably mounted within the guide hole 13.

[0050] The upper die 2 is provided with a punching head 21, a punching punch 22 and a positioning column 23. The punching punch 22 is used to enter the first stamping station 12 to punch out a positioning hole 51 for the steel strip raw material 5. Except for the first stamping station 12, the remaining stamping stations 12 all have corresponding positioning columns 23, so that when various parts of the steel strip raw material 5 are moved from the first stamping station 12 to the remaining stamping stations 12, the positioning columns 23 are used to insert into the positioning holes 51 to position various parts of the steel strip raw material 5; the positioning columns 23 are movably arranged on the upper die 2, and the positioning columns 23 can be lifted and lowered by being mounted in the upper die 2 without falling off. The upper die 2 is provided with a distance sensor 24 located above the positioning column 23. The distance sensor 24 is used to measure the distance from the top of the positioning column 23. The distance sensor 24 can be an infrared distance sensor; the bottom end of the positioning column 23 is provided with a pulley 231, which is used to contact the steel strip raw material 5 and slide on the surface of the steel strip raw material 5. Each stamping station 12 has a corresponding punch head 21 that can enter the punch head 21. The punch head 21 is used to stamp the steel strip material 5 in the stamping station 12. The upper die 2 is provided with a floating fixed plate 25 that can be raised and lowered. The fixed plate 25 can be raised and lowered by sliding on the guide pillars. The fixed plate 25 can be mounted on the bottom of the guide pillars by setting a limiter to prevent it from separating from the upper die 2. When the upper die 2 and the lower die 1 are closed, the fixed plate 25 is pre-contacted with the steel strip material 5 by its own weight or the thrust of the spring 14 to fix the steel strip material 5.

[0051] The blank conveying mechanism includes a first winding mechanism 3 and a second winding mechanism 4. The first winding mechanism 3 winds up the steel strip raw material 5. One end of the steel strip raw material 5 is pulled out from the first winding mechanism 3 into the material channel 11 and passes through all the stamping stations 12 and is finally wound up on the second winding mechanism 4. The first winding mechanism 3 is connected to an auxiliary power module, which can be a motor. The second winding mechanism 4 is connected to a conveying power module, which can be a motor. The conveying power module is used to drive the second winding mechanism 4 to reel the steel strip raw material 5, so that various parts of the steel strip raw material 5 are pulled out from the first winding mechanism 3 and moved in sequence and orderly to the stamping station 12 for stamping processing by the punch head 21.

[0052] The following is a working description of the stamping die described in this embodiment.

[0053] One end of the steel strip material 5 is pulled out from the first winding mechanism 3 into the material channel 11 and passes through all the stamping stations 12 and is finally wound up in the second winding mechanism 4. During the stamping process, the upper die 2 and the lower die 1 are closed. At this time, the fixing plate 25 is in contact with the steel strip material 5 in advance to fix the steel strip material 5; then, the punch head 21 punches a certain part of the steel strip material 5 in the stamping station 12. At the same time, the punch 22 punches a positioning hole 51 in the steel strip material 5 in the first stamping station 12. After that, the upper die 2 and the lower die 1 are opened, and the punch head 21 and the punch 22 are away from the steel strip material 5; then, the upper die 2 and the lower die 1 are moved closer to each other so that the pulley 231 is in contact with the steel strip material 5. Afterwards, the conveying power module drives the second winding mechanism 4 to wind the steel strip material 5, so that the steel strip material 5 moves in the material passage 11, thereby driving the portion of the steel strip material 5 located in the front stamping station 12 to move to the next stamping station 12 to be stamped, driving the portion of the steel strip material 5 located in the last stamping station 12 to move out of the material passage 11 for discharge, and driving the new portion of the steel strip material 5 to enter the first stamping station 12 to be stamped. When the steel strip material 5 moves, the pulley 231 slides on the surface of the steel strip material 5 until the pulley 231 slides into the positioning hole 51. When the distance sensor 24 senses that the positioning column 23 is away, the pulley 231 slides into the positioning hole 51. At this time, the distance sensor 24 sends a signal to close the upper mold 2 and the lower mold 1 for a second pressing; and so on, until the processed part on the steel strip material 5 passes through all the pressing stations.

[0054] When the upper mold 2 and the lower mold 1 are closed, the fixed plate 25 pushes the steel strip raw material 5 to push the ejector pin 15 into the guide hole 13; when the upper mold 2 and the lower mold 1 are opened, the spring 14 pushes the ejector pin 15 to extend to the stamping station 12 to separate the steel strip raw material 5 from the stamping station 12.
