Description

Technical Field

[0001] This invention relates to the field of stationery box processing technology, specifically to a stamping die blanking device for stationery box processing. Background Technology

[0002] A pencil case is a box used by students to store stationery such as pens, pencils, rulers, and erasers. They come in many materials, including wood, iron, and plastic, and vary in shape, but are mostly rectangular. Metal pencil cases require molds for stamping and forming. Most existing stationery box stamping and unloading devices use an external swinging robotic arm to load and unload the stamped stationery boxes at fixed points. The stationery box is formed by a stamping block pressing a metal plate placed above the stamping die to separate the finished product from the sheet metal. When the stamping block rises after pressing the metal plate, it may bring up the stamped stationery box and surrounding waste material, causing the position of the formed stationery box to change. This makes it difficult for the external swinging robotic arm to unload the stationery box that has changed position. Stationery boxes that are not successfully unloaded can easily affect the next stamping, thus affecting the efficiency of stationery box loading and unloading and reducing the yield rate of stationery box stamping. Summary of the Invention

[0003] The purpose of this invention is to provide a stamping die blanking device for processing stationery boxes, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a stamping die blanking device for processing stationery boxes, comprising a main body, a stamping block slidably connected to the top inner wall of the main body, and further comprising: The demolding mechanism is installed at the bottom of the stamping block. When the demolding mechanism is in operation, it reduces the chance of the stamped pencil case being lifted up by the stamping block. The anti-wrinkle mechanism is installed at the bottom of the demolding mechanism. When the anti-wrinkle mechanism is in operation, it can reduce the bending of the raw material plate caused by the pushing of the internal parts of the demolding mechanism.

[0008] Furthermore, the stamping assembly includes a push plate fixedly connected to the front and back of the stamping block; Two rotating plates are provided at the bottom of the push plate. The two rotating plates are staggered around the stamping block and are rotatably connected to the inner wall of the main body. A mold is provided on the top of the rotating plate, and the mold is slidably connected to the bottom inner wall of the main body; The bottom of the mold is provided with two partition plates, which are symmetrically distributed around the stamping block. The partition plates are slidably connected to the bottom inner wall of the stamping block. The isolation plate has several springs fixedly connected to its side wall. These springs are evenly distributed around the mold, and the side of the mold furthest from the isolation plate is fixedly connected to the side wall of the main body.

[0009] Furthermore, the support components include support blocks fixedly connected to the left and right sides of the main body; The detachment component includes several elastic plates fixedly connected to the bottom of the stamping block, with the elastic plates arranged in groups of five symmetrically around the stamping block.

[0010] Furthermore, the detachment assembly includes a push-off plate fixedly connected to the bottom of several elastic plates, and a connecting rod is rotatably connected to the side wall of the push-off plate; A movable plate is rotatably connected to the side of the connecting rod away from the push plate, and the side of the movable plate close to the push plate is rotatably connected to the side wall of the push plate. The side of the movable plate away from the push plate is rotatably connected to a one-way wheel; The top of the movable plate is fixedly connected to a reset plate, and the side of the reset plate away from the movable plate is fixedly connected to the side wall of the main body.

[0011] Furthermore, the auxiliary components include two separation plates slidably connected to the top of the push-off plate, the two separation plates being symmetrically distributed around the stamping block; Several springs are fixedly connected to the side wall of the separation plate, and the springs are linearly distributed around the separation plate. The side of spring two furthest from the separation plate is fixedly connected to the side wall of the push-off plate; Two teeth are provided on the right side of the spring two, and the two teeth are fixedly connected to the front and back of the one-way wheel respectively; The top of the tooth is equipped with a blocking tooth, which is rotatably connected to the side wall of the movable plate; A spring three is fixedly connected to the top of the blocking tooth, and the side of the spring three away from the blocking tooth is fixedly connected to the inner wall of the movable plate.

[0012] Furthermore, the leveling assembly includes two synchronizing rods slidably connected to the side wall of the push-off plate, the two synchronizing rods being symmetrically distributed around the stamping block; A rising block is fixedly connected to the bottom of the synchronizing rod, and two rotating blocks are rotatably connected to the bottom of the rising block. The two rotating blocks are evenly distributed with respect to the pushing plate. The side of the rotating block away from the rising block is rotatably connected to the bottom inner wall of the main body.

[0013] Furthermore, the tensioning assembly includes a deformation rod that is slidably connected to the side wall of the synchronizing rod; A spring piece is fixedly connected to the bottom of the deformation rod, and the side of the spring piece away from the deformation rod is fixedly connected to the side wall of the synchronizing rod. A drive plate is provided between the two spring pieces, and the left and right sides of the drive plate are rotatably connected to the side wall of the deformation rod; The bottom of the drive plate is fixedly connected with three rubber strips, and the bottom of the drive plate has an inclined surface.

[0014] The present invention has the following beneficial effects: 1. In this invention, the push plate is pushed into the separation plate and pops out under the push of spring two. This reduces the situation where the movement of spring two and the downward movement of the push plate will cause the stamped metal plate and the unstamped metal plate on the outside of the stamping block to be lifted by the movement of the stamping block when a stamped metal plate is lifted. Due to the setting of the push plate and the one-way wheel, the situation where the metal plate is lifted by the stamping block after being stamped and affects the next stamping is reduced. At the same time, the stamped pencil box completes the automatic loading and unloading process as the push plate and the one-way wheel move to the left, which further improves the loading and unloading efficiency after the pencil box is stamped, and indirectly improves the yield rate of the pencil box during stamping.

[0015] 2. In this invention, the rising height of the rising block is consistent with the rising height of the mold. Since the height of the rising block after rising is consistent with the height of the mold after movement, the push plate will first contact the rising block after movement when it descends. Due to the movement of the rising block, the deformation caused by the rising of the mold on the metal plate when the push plate moves downward will be reduced. This will prevent the stamping block from cutting the same amount of material required to stamp into the pencil box during the descent process, further improving the flatness of the metal plate when the pencil box is stamped, and indirectly improving the cutting rate of the metal plate by the stamping block.

[0016] 3. In this invention, the upward movement of the lifting block to the right will cause the top metal plate near the deformation rod to tilt upward. The side of the lifting block near the one-way wheel will first contact the bottom of the metal plate when the lifting block moves. When the metal plate tilts upward on the side near the deformation rod, the deformation area of ​​the deformation rod will block the tilted part of the metal plate. Due to the setting of the deformation rod, the situation where the tilted metal plate moves towards the one-way wheel when the pushing plate moves is reduced due to the tilting of the metal plate to the bottom area of ​​the pushing plate. This further improves the smoothness of loading and unloading of the pencil case before and after stamping.

[0017] 4. In this invention, when the metal plate is lifted, it forms an arc surface. The metal plate does not make close contact with the mold and the plane of the rising block. The setting of the driving plate and the movement of the driving plate will cause the metal plate to move to the left. At this time, there is a one-way wheel on the right side for fixation. The highest point of the arc surface formed by the metal plate will move closer to the top of the mold, reducing the gap between the arc surface and the mold. This indirectly reduces the situation of excessive material during stamping, resulting in wrinkles and material accumulation on the stamped stationery box, and further improves the aesthetic appearance of the stamped stationery.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 - Figure 11 As shown, the present invention is a stamping die blanking device for processing stationery boxes, including a main body 1, a stamping block 101 slidably connected to the top inner wall of the main body 1, and further including: Demolding mechanism 2 is installed at the bottom of stamping block 101. When demolding mechanism 2 is in operation, it reduces the chance of the stamped pencil box being lifted up by stamping block 101. Anti-wrinkle mechanism 3 is installed at the bottom of demolding mechanism 2. When the anti-wrinkle mechanism 3 is in operation, it can reduce the bending of the raw material plate caused by the pushing of the internal parts of demolding mechanism 2.

[0024] Entity 1 includes: Stamping assembly 11 is disposed on the top inner wall of the main body 1; Support component 12 is disposed on the side wall of stamping component 11.

[0025] Demolding mechanism 2 includes: Disengagement component 21 is located at the bottom of stamping block 101; Auxiliary component 22 is located inside the component detached from 21.

[0026] Anti-crease mechanism 3 includes: A leveling component 31 is disposed on the bottom inner wall of the main body 1; The tensioning component 32 is disposed on the side wall of the flattening component 31.

[0027] The stamping assembly 11 includes a push plate 111 fixedly connected to the front and back sides of the stamping block 101; Two rotating plates 112 are provided at the bottom of the push plate 111. The two rotating plates 112 are staggered around the stamping block 101. The rotating plates 112 are rotatably connected to the inner wall of the main body 1. A mold 113 is provided on the top of the rotating plate 112, and the mold 113 is slidably connected to the bottom inner wall of the main body 1; The bottom of the mold 113 is provided with two partition plates 114, which are symmetrically distributed around the stamping block 101. The partition plates 114 are slidably connected to the bottom inner wall of the stamping block 101. Among them, several springs are fixedly connected to the side wall of the isolation plate 114. The springs are evenly distributed around the mold 113. The side of the mold 113 away from the isolation plate 114 is fixedly connected to the side wall of the main body 1. The movement of the stamping block 101 will drive the push plate 111 to move synchronously. The movement of the push plate 111 will drive the rotating plate 112 to rotate. The simultaneous rotation of the two rotating plates 112 will push the mold 113 to move upward. The stamping block 101 and the mold 113 squeeze each other to complete the stamping of the metal plate.

[0028] Support component 12 includes support blocks 121 fixedly connected to the left and right sides of the main body 1; The detachment component 21 includes several elastic plates 211 fixedly connected to the bottom of the stamping block 101. The elastic plates 211 are distributed symmetrically with five of them around the stamping block 101.

[0029] The release assembly 21 includes a push-off plate 212 fixedly connected to the bottom of a plurality of elastic plates 211, and a connecting rod 213 is rotatably connected to the side wall of the push-off plate 212; A movable plate 214 is rotatably connected to the side of the connecting rod 213 away from the push plate 212, and the side of the movable plate 214 near the push plate 212 is rotatably connected to the side wall of the push plate 111. A one-way wheel 215 is rotatably connected to the side of the movable plate 214 away from the push plate 111; Among them, a reset plate is fixedly connected to the top of the movable plate 214. The side of the reset plate away from the movable plate 214 is fixedly connected to the side wall of the main body 1. The movement of the stamping block 101 will squeeze the elastic plate 211, causing the elastic plate 211 to deform and thus continue to exert elastic force. When the top inner wall of the stamping block 101 contacts the top of the push-off plate 212, the stamping block 101 is at the lowest point, which is the state of stamping completion.

[0030] The auxiliary component 22 includes two separation plates 221 that are slidably connected to the top of the push-off plate 212, and the two separation plates 221 are symmetrically distributed with the stamping block 101 as the center. A number of springs 222 are fixedly connected to the side wall of the separation plate 221, and the springs 222 are linearly distributed around the separation plate 221. The side of spring 222 away from the separation plate 221 is fixedly connected to the side wall of the push-off plate 212; Two teeth 223 are provided on the right side of the second spring 222, and the two teeth 223 are fixedly connected to the front and back of the one-way wheel 215 respectively; The top of the tooth 223 is provided with a blocking tooth 224, which is rotatably connected to the side wall of the movable plate 214. A spring three is fixedly connected to the top of the blocking tooth 224. The side of the spring three away from the blocking tooth 224 is fixedly connected to the inner wall of the movable plate 214. The teeth 223 on the side wall of the one-way wheel 215 and the blocking tooth 224 are arranged so that the one-way wheel 215 will not rotate when it moves toward the stamping block 101.

[0031] The leveling component 31 includes two synchronizing rods 311 that are slidably connected to the side wall of the push-off plate 212. The two synchronizing rods 311 are symmetrically distributed with the stamping block 101 as the center. The bottom of the synchronizing rod 311 is fixedly connected to a rising block 312, and the bottom of the rising block 312 is rotatably connected to two rotating blocks 313, which are equidistantly distributed with respect to the pushing plate 212. The side of the rotating block 313 away from the rising block 312 is rotatably connected to the bottom inner wall of the main body 1. The rotation of the rotating block 313 will cause the rising block 312 to rise when it moves in the direction of the one-way wheel 215. When the rising block 312 moves in the direction of the one-way wheel 215, it will squeeze the top return plate 314 and deform it, causing the top return plate 314 to bulge upward.

[0032] The tensioning assembly 32 includes a deformation rod 321 that is slidably connected to the side wall of the synchronizing rod 311; A spring piece 322 is fixedly connected to the bottom of the deformation rod 321, and the side of the spring piece 322 away from the deformation rod 321 is fixedly connected to the side wall of the synchronizing rod 311. A drive plate 323 is provided between the two spring pieces 322, and the left and right sides of the drive plate 323 are rotatably connected to the side walls of the deformation rod 321. Among them, three rubber strips are fixedly connected to the bottom of the driving plate 323. The bottom of the driving plate 323 has an inclined surface. When the deformation rod 321 deforms, the driving plate 323 between the deformation rods 321 will be squeezed by both sides and deform to a certain extent, so that the driving plate 323 gradually approaches the surface of the metal plate and finally contacts the metal plate. At this time, the top push plate 212 will continue to move downward. At this time, the driving plate 323 applies downward pressure to the metal plate under the action of the downward moving deformation rod 321.

[0033] In use, the operator first places the long strip of metal to be stamped into the bottom inner wall of the main body 1, with one side of the metal plate placed at the bottom of the stamping block 101. Then the machine is started, and the stamping block 101 moves downward. The movement of the stamping block 101 drives the push plate 111 to move synchronously. The movement of the push plate 111 drives the rotating plate 112 to rotate. The simultaneous rotation of the two rotating plates 112 pushes the mold 113 upward. The mutual squeezing of the stamping block 101 and the mold 113 completes the stamping of the metal plate. After the stamping is completed, the stamping block 101 rises. Due to the rise of the stamping block 101, the pushing force on the rotating plate 112 disappears. Under the influence of its own gravity, the rotating plate 112 rotates downward to complete the reset. The mold 113 moves downward when the rotating plate 112 resets to complete the unloading.

[0034] When the stamping block 101 moves downward, the one-way wheel 215 first contacts the stamping platform. Under the downward thrust of the stamping block 101, the movable plate 214 rotates under the drive of the one-way wheel 215, causing the side not connected to the push plate 111 to move away from the push plate 212. At this time, the reset plate at the top of the movable plate 214 is deformed by compression. As the movable plate 214 gradually moves away from the push plate 212, it will drive the push plate 212 to move in the direction of the one-way wheel 215. At this time, the stamping block 101 is still descending. Due to the drive of the movable plate 214, the push plate 212 gradually moves to directly below the stamping block 101. When the stamping block 101 continues to move downward, the cutting part of the stamping block 101 will pass through... When the stamping block 101 partially passes through the pusher plate 212, it pushes the separating plate 221 outward. The continued downward pressure of the stamping block 101 causes the pusher plate 212 to contact the bottom metal. The movement of the stamping block 101 compresses the elastic plate 211, causing it to deform and accumulate elastic force. When the top inner wall of the stamping block 101 contacts the top of the pusher plate 212, the stamping block 101 is at its lowest point, indicating the stamping is complete. After stamping, the stamping block 101 begins to move upward. At this time, the pusher plate 212 moves downward under the push of the elastic plate 211, causing the bottom of the pusher plate 212 to adhere to the top of the metal plate. At this point, due to… The upward movement of the stamping block 101 causes the deformed reset plate to push the movable plate 214 to rotate closer to the stamping block 101. Due to the teeth 223 and blocking teeth 224 on the side wall of the one-way wheel 215, it does not rotate when it moves closer to the stamping block 101. At the same time, the rotation of the movable plate 214 toward the stamping block 101 will drive the connecting rod 213 to apply a leftward thrust to the push plate 212. At this time, under the combined influence of the metal plate being attached to the bottom of the push plate 212 and the one-way wheel 215 not rotating when moving toward the stamping block 101, the automatic feeding and unloading of the metal plate is completed. As the stamping block 101 gradually moves away from the push plate 212, the push plate 212 is squeezed. The separation plate 221 will pop out under the push of the second spring 222, thereby reducing the situation where the movement of the second spring 222 and the downward movement of the push plate 212 will cause the stamped metal plate and the unstamped metal plate on the outside of the stamping block 101 to be lifted by the movement of the stamping block 101 when the stamped metal plate is lifted. Due to the setting of the push plate 212 and the one-way wheel 215, the situation where the metal plate is lifted by the stamping block 101 after being stamped and affects the next stamping is reduced. At the same time, the stamped pencil box completes the automatic loading and unloading process by the leftward movement of the push plate 212 and the one-way wheel 215, which further improves the loading and unloading efficiency after the pencil box is stamped, and indirectly improves the yield rate of the pencil box during stamping.

[0035] When the stamping block 101 descends, the pusher plate 212 moves towards the one-way wheel 215. This movement of the pusher plate 212 towards the one-way wheel 215 causes the synchronizing rod 311 to move towards the one-way wheel 215. The movement of the synchronizing rod 311 causes the lifting block 312 to move towards the one-way wheel 215. As the lifting block 312 moves towards the one-way wheel 215, the rotating block 313 at the bottom of the lifting block 312 rotates under its influence. This rotation causes the lifting block 312 to rise as it moves towards the one-way wheel 215. When the lifting block 312 moves towards the one-way wheel 215, it presses against the return plate 314. The deformation causes the top return plate 314 to bulge upwards, and the rising height of the rising block 312 is consistent with the rising height of the mold 113. Since the rising block 312 is consistent with the height of the mold 113 after it moves after it rises, the push plate 212 will first contact the rising block 312 after it moves down. Due to the movement of the rising block 312, the deformation caused by the rising of the mold 113 on the metal plate when the push plate 212 moves down will be reduced. This will cause the stamping block 101 to be unable to cut the same amount of material required to stamp into the pencil box during the descent process, which will further improve the flatness of the metal plate when the pencil box is stamped, and indirectly improve the cutting rate of the metal plate by the stamping block 101.

[0036] When the synchronizing rod 311 moves towards the one-way wheel 215, its movement drives the deformation rod 321 to move towards the one-way wheel 215. At this time, the end of the deformation rod 321 near the push plate 111 is squeezed by the push plate 111 and moves towards the synchronizing rod 311. When the end of the deformation rod 321 near the push plate 111 moves, the deformation area in the middle of the deformation rod 321 deforms, and the two deformation rods 321 deform in opposite directions. After deformation, the top of the deformation rod 321 is squeezed by the push plate 212 as it descends, causing it to move synchronously with the descent of the push plate 212. At this time, the spring piece 322 accumulates elastic force under the pressure of the push plate 212. After the compression is complete, the elastic force of the spring piece 322 is released, causing the deformation rod 321 to reset, thus not affecting the feeding operation of the extruded pencil box. The deformation area of ​​the deformation rod 321 is located near the push plate 111. When the metal plate is deformed under the push of 1, it will be located on the outside of the pushed plate 212 after the movement. When the metal plate is just put into the stamping area, since there is no waste material connected to the metal plate formed by stamping the stationery box on the left side of the stamping area, the upward and rightward movement of the lifting block 312 will push the side of the top metal plate near the deformation rod 321 to tilt up. The side of the lifting block 312 near the one-way wheel 215 will contact the bottom of the metal plate first when the lifting block 312 moves. When the metal plate tilts up on the side near the deformation rod 321, the deformation area of ​​the deformation rod 321 will block the tilted part of the metal plate. Due to the setting of the deformation rod 321, the situation where the metal plate tilts to the bottom area of ​​the push plate 212 and the push plate 212 moves will be reduced, thus driving the tilted metal plate to move towards the one-way wheel 215, thereby further improving the smoothness of loading and unloading of the stationery box before and after stamping.

[0037] When the deformation rod 321 deforms, the driving plate 323 between the deformation rods 321 will deform due to the pressure from both sides when the deformation rod 321 deforms. This causes the driving plate 323 to gradually approach the surface of the metal plate and eventually contact it. At this time, the top push plate 212 will continue to move downward. Driven by the downward-moving deformation rod 321, the driving plate 323 applies downward pressure to the metal plate. Under the push of the deformation rod 321 and the obstruction of the bottom metal plate, the driving plate 323 will rotate on the deformation rod 321. When the driving plate 323 rotates under pressure, the inclined surface on the top will contact the bottom metal plate. The top deformation rod 321 will continue to apply downward force to the driving plate 323 due to the continued pressure from the top push plate 212. Since the inclined surface of the driving plate 323 is already in contact with the metal plate, When pressure is applied to the metal plate, the drive plate 323 will continue to rotate to the left. When the drive plate 323 rotates, the rubber strip at the bottom of the drive plate 323 will move the bottom metal plate a distance to the left. At this time, the metal plate is in a state where it is lifted by the mold 113 and the rising block 312. When the metal plate is lifted, it will form an arc surface. The metal plate will not be in close contact with the plane of the mold 113 and the rising block 312. The setting of the drive plate 323 and the movement of the drive plate 323 will drive the metal plate to move to the left. At this time, there is a one-way wheel 215 on the right side for fixing. The highest point of the arc surface formed by the metal plate will move closer to the top of the mold 113, reducing the gap between the arc surface and the mold 113. This indirectly reduces the situation where too much material is used during stamping, resulting in wrinkles and material accumulation on the stamped stationery box, and further improves the aesthetic appearance of the stamped stationery.
