[0027] The present application provides a blanking device 100, which can be applied to the blanking processing of the material belt 200 in the electronic, hardware and other industries, so as to efficiently and accurately complete the blanking separation of the product 2001 from the material belt 200, and realize the convenient collection of the product 2001.

[0028] As shown in the figure, the blanking device 100 provided by the embodiment of the present application comprises: Figure 1 A first die 1 and a second die 2, the first die 1 and the second die 2 are oppositely arranged along a vertical direction, the second die 2 comprises a first sub-die 21 and a second sub-die 22 oppositely arranged along a horizontal direction, the first sub-die 21 and the second sub-die 22 have a material belt passage therebetween, the material belt passage extends along the vertical direction and can pass through the material belt 200, and the first sub-die 21 or the second sub-die 22 has a bearing part 23, the bearing part 23 can fix the material belt 200; A cutting knife 3, one end of the cutting knife 3 is connected to the first die 1, the other end of the cutting knife 3 faces the bearing part 23, and the first die 1 can drive the cutting knife 3 to move along the vertical direction and approach the bearing part 23; A material receiving part 4, the material receiving part 4 faces the bearing part 23, and the material receiving part 4 can collect the cut product 2001.

[0029] ​As shown in Figure 1 The first die 1 and the second die 2 are arranged opposite to each other along the vertical direction to form a basic blanking frame structure. The first die 1 can include a die holder, a backing plate and a clamp plate, and the second die 2 can also include a die holder, a backing plate and a clamp plate. Among them, the first die 1 can move along the vertical direction to approach the second die 2.

[0030] Among them, the first die 1 can be made of high-strength alloy material, so that its structure is firm enough to withstand the reaction force in the blanking process. The first die 1 can be connected and guided with the second die 2 through guide columns, so as to improve the accuracy of the first die 1 when moving along the vertical direction, so that the cutting knife 3 on the first die 1 can accurately cooperate with the material belt 200 on the bearing part 23 for blanking.

[0031] As shown in Figure 2 The second die 2 can include a first sub-die 21 and a second sub-die 22 arranged opposite to each other along the horizontal direction, and a material belt passage is formed between the two, through which the material belt 200 can pass along the vertical direction for blanking. Among them, the first sub-die 21 and the second sub-die 22 can be made of high-strength alloy steel material respectively, so that the second die 2 has high hardness, high wear resistance and good toughness, so as to withstand the huge pressure and friction force generated in the blanking process, thereby ensuring the service life and blanking accuracy of the blanking device 100.

[0032] Among them, the material belt passage is located between the first sub-die 21 and the second sub-die 22, and its width is designed according to the width of the processed material belt 200, which is generally slightly larger than the width of the material belt 200, which can not only ensure the smooth passing of the material belt 200, but also effectively limit the transverse movement of the material belt 200, thereby improving the blanking accuracy.

[0033] With this design, the material belt 200 can move stably along the established passage when entering the device for blanking, and the transverse shaking and deviation of the material belt 200 can be limited. At the same time, the bearing part 23 arranged on the first sub-die 21 or the second sub-die 22 can also firmly fix the material belt 200. The bearing part 23 can be designed according to the characteristics of the material belt 200 and the product 2001, such as its shape being adapted to the bottom profile of the product 2001, the surface being treated with special anti-slip treatment or increasing the friction texture, to ensure that the material belt 200 will not displace due to the impact force of the cutting knife 3 when the cutting knife 3 is blanking the material belt 200, thereby ensuring the accuracy of the blanking position and improving the dimensional accuracy and shape accuracy of the product 2001.

[0034] The inner wall of the material belt channel can be polished to reduce the friction between the material belt 200 and the inner wall of the channel, so that the material belt 200 can move smoothly in the vertical direction, and deformation or damage of the material belt 200 caused by excessive friction can be avoided.

[0035] As shown in Figure 2 and Figure 3 , a bearing part 23, i.e. a processing part, can be arranged on the first sub-mold 21. The bearing part 23 can be a groove 5112 structure with a certain depth and width. The depth can be designed according to the size of the material belt 200 to ensure that the product 2001 on the material belt 200 can be stably carried, thereby facilitating the subsequent cutting process.

[0036] The surface of the bearing part 23 can be treated by special treatment, such as hard chromium plating process, to increase the hardness and wear resistance of the surface, and to increase the friction between the material belt 200 and the bearing part 23, thereby preventing the material belt 200 from moving during the punching process.

[0037] As shown in Figure 2 and Figure 3 , the cutting tool 3 is connected to the first mold 1, so that the first mold 1 can drive the cutting tool 3 to move in the vertical direction and punch and separate the product 2001 on the material belt 200. One end of the cutting tool 3 can be fixed to the lower surface of the first mold 1 by bolts, so as to ensure that the connection between the cutting tool 3 and the first mold 1 is firm and reliable, and will not loosen during the punching process. In this way, vertical punching can be realized, the punching process can be controlled, and the risk of damage to the product 2001 can be reduced.

[0038] The first mold 1 can be driven by an external power source such as a hydraulic cylinder or an air cylinder to drive the cutting tool 3 to move reciprocally in the vertical direction. During the punching process, the first mold 1 moves downward to drive the cutting tool 3 to gradually approach the material belt 200 on the bearing part 23. When the cutting tool 3 contacts the material belt 200, a pressure is applied to the material belt 200 to punch and separate the product 2001 from the material belt 200. After the punching is completed, the first mold 1 moves upward to drive the cutting tool 3 away from the bearing part 23 and prepares for the next punching. In this way, the vertical punching avoids the lateral force that may be caused by oblique punching, thereby reducing the deformation of the material belt 200 and the wear of the device caused by the lateral force.

[0039] In one embodiment, the cutting tool 3 can be made of high-speed steel, which has high hardness and good wear resistance, so as to maintain a sharp cutting edge during high-speed punching, thereby ensuring that the edges of the punched product 2001 are neat, smooth, burr-free and flash-free.

[0040] In one embodiment, the shape of the cutter 3 can be designed according to the shape of the product 2001. For example, if the product 2001 is rectangular, the cutting edge of the cutter 3 is also rectangular, and the size of the cutter 3 is slightly larger than the size of the product 2001, so as to ensure that the product 2001 can be completely cut off from the strip 200.

[0041] In one embodiment, an elastic gasket can be provided at the connection between the cutter 3 and the first mold 1. The elastic gasket is made of elastic materials such as rubber and has a certain elastic deformation capability. During the punching process, the elastic gasket can play a buffering role, reducing the impact force between the cutter 3 and the first mold 1, thereby extending the service life of the first mold 1. At the same time, it can also ensure the stability of the cutter 3 during the punching process and improve the punching quality.

[0042] like Figure 1 and Figure 3 As shown, the receiving component 4 is connected to the second mold 2 with its receiving end facing the carrier part 23, enabling it to collect the cut products 2001 through the receiving end, thereby realizing an automated production process. This also eliminates the need for manual collection of products 2001, reducing downtime during production and allowing the production line to operate continuously and stably, thus improving overall production efficiency.

[0043] The receiving end can be an inclined trough-shaped structure, with the inclination angle designed according to the falling speed of product 2001 and collection requirements. Generally, the inclination angle is between 30° and 60°. For example, an inclination angle of 45° can be selected so that the cut product 2001 can smoothly slide into the receiving part 4 under its own gravity, thereby realizing automatic collection.

[0044] In one embodiment, the receiving part 4 can be made of materials such as stainless steel. Stainless steel has the advantages of corrosion resistance and easy cleaning, which can ensure that the receiving part 4 is not corroded during long-term use, so as to maintain a smooth surface and reduce the friction between the product 2001 and the receiving part 4, thereby allowing the product 2001 to slide smoothly into the collection container.

[0045] In one embodiment, the surface of the receiving component 4 may be polished to improve the sliding performance of the product 2001, thereby ensuring the smooth collection of the product 2001.

[0046] In the punching process, the material belt 200 can be inserted from above the material belt passage, so that the material belt 200 can move vertically downward along the material belt passage until the product 2001 on the material belt 200 is above the bearing part 23. By adjusting the position of the material belt 200, the product 2001 can be accurately placed in the center of the bearing part 23. Then, the external power source is started to drive the first die 1 to move downward, and the first die 1 can drive the cutting knife 3 to gradually approach the material belt 200 on the bearing part 23. When the cutting knife 3 contacts the material belt 200, the material belt 200 is pressed, and the product 2001 is punched and separated from the material belt 200. Then, the cut product 2001 can fall from the bearing part 23 into the receiving member 4 below under the action of gravity, slide along the inclined surface of the receiving member 4 to achieve automatic collection. Finally, the external power source drives the first die 1 to move upward, and the first die 1 drives the cutting knife 3 away from the bearing part 23 to return to the initial position and prepare for the next punching. By repeating the above steps, continuous punching of the material belt 200 can be achieved.

[0047] In this way, the material belt 200 can continuously pass through the material belt passage in the vertical direction to enter the punching device 100 for punching processing. The first die 1 can quickly and accurately drive the cutting knife 3 to reciprocate under the drive of the power device, and high-speed punching can be achieved. Compared with the traditional intermittent punching device 100, the interval time between each punching is shortened, and the punching frequency per unit time is increased, thereby improving the production efficiency.

[0048] As shown in Figure 6 , the cut product 2001 can fall from the bearing part 23 into the receiving member 4 below under the action of gravity, slide along the inclined surface of the receiving member 4 to achieve automatic collection. Then, the receiving member 4 can move transversely to the suction area, and the suction disc in the receiving member 4 can adsorb the product 2001 and place the product 2001 in the product seat 300, thereby achieving the transportation of the product seat 300. In this way, the receiving member 4 only needs to move linearly without turning, which helps to save the punching time and avoid damage to the product 2001 caused by the turning process.

[0049] Optionally, a first positioning member 5 is further included, which is arranged on the second die 2 and can position the material belt 200 in the horizontal direction.

[0050] As shown in Figure 1 and Figure 2As shown, the second mold 2, also known as the lower mold, includes a first sub-mold 21, a second sub-mold 22, a lower mold base, and a lower backing plate. The lower backing plate is located between the first sub-mold 21, the second sub-mold 22, and the lower mold base. A first positioning element 5 can be provided on the lower mold base so that the first positioning element 5 can position the strip 200 passing through it in the horizontal direction, that is, the relative direction of the first sub-mold 21 and the second sub-mold 22, thereby improving the accuracy of subsequent punching.

[0051] Optionally, the first positioning member 5 includes a positioning block 51 and a positioning pin 52, one end of the positioning pin 52 is connected to the positioning block 51, and the other end of the positioning pin 52 can be inserted into the first positioning hole of the material strip 200.

[0052] like Figure 4 As shown, the positioning block 51 can be placed on the lower mold base, and the positioning pin 52 can be connected to the positioning block 51, so that the positioning pin 52 can form a threaded connection, snap-fit ​​connection or other connection with the first positioning hole of the strip 200, thereby realizing the positioning of the strip 200. The top opening of the positioning block 51 can be provided to facilitate the connection of the positioning pin 52.

[0053] Optionally, the positioning block 51 includes a support 511, the support 511 having a baffle 5111 extending along the vertical direction, the baffle 5111 being able to abut against the material strip 200 that passes through it, and the positioning pin 52 passing through the baffle 5111 and connected to the first positioning hole.

[0054] like Figure 4 As shown, the support 511 can be an L-shaped structure or a near-L-shaped structure, and its interior has a baffle 5111 extending in the vertical direction, which can be used to limit the passing material strip 200, so as to facilitate the convenient and reliable connection of the positioning pin 52. In this case, depending on the actual design, the support 511 and the baffle 5111 can be integrally formed, or they can be formed independently.

[0055] like Figure 4 As shown, the positioning block 51 may also include a connecting seat, which is connected to the support 511 in a vertical direction. The connecting seat is used to fix one end of the positioning pin 52, and the other end of the positioning pin 52 passes through the through hole of the baffle 5111 and is connected to the first positioning hole of the material belt 200.

[0056] In one embodiment, the connector may be Figure 4 The L-shaped structure shown has one side abutting against the baffle 5111 and the other side parallel to the baffle 5111, so as to facilitate the assembly of the positioning block 51.

[0058] like Figure 4 As shown, the positioning pin 52 may include a large-diameter portion and a small-diameter portion. One end of the large-diameter portion can be connected to one end of the small-diameter portion, the other end of the large-diameter portion can be connected to the connecting seat or support 511, and the other end of the small-diameter portion can be connected to the first positioning hole of the material strip 200. Depending on the actual design, the large-diameter portion and the small-diameter portion can be integrally formed, or they can be formed independently.

[0059] In one embodiment, an external thread can be provided on the small diameter portion, and a corresponding internal thread can be provided in the through hole of the baffle 5111, so that the positioning of the first positioning hole of the strip 200 can be achieved by utilizing the threaded engagement of the two.

[0060] In one embodiment, a first spring 53 may be fitted around the outer periphery of the small diameter portion. One end of the first spring 53 abuts against the large diameter portion, and the other end of the first spring 53 abuts against the baffle 5111. This allows the elastic deformation of the first spring 53 to adjust the insertion depth of the positioning pin 52 and the baffle 5111, thereby adjusting the positioning position of the positioning pin 52 to better adapt to the positioning requirements of different material strips 200.

[0061] In one embodiment, a force transmission rod 54 can also be provided, with one end of the force transmission rod 54 passing through the through hole of the connecting seat and connected to the large diameter part of the positioning pin 52. The other end of the force transmission rod 54 can be connected to the drive structure, so that the drive structure can drive the positioning pin 52 to move through the force transmission rod 54 and realize the engagement of the positioning pin 52 with the first positioning hole of the material strip 200.

[0062] In one embodiment, a horizontal groove 5112 can also be formed on the support 511, with the opening of the groove 5112 facing the baffle 5111, and the sidewall of the groove 5112 being on the same horizontal plane as the bearing portion 23. Thus, when punching the product 2001 of the strip 200 on the bearing portion 23, the groove 5112, being on the same horizontal plane, can also support the remaining products 2001 on the strip 200, thereby enabling vertical positioning of the strip 200, preventing punching abnormalities caused by strip 200 displacement during punching, and facilitating convenient punching of the remaining products 2001 on the strip 200, thus improving punching efficiency.

[0063] Optionally, a second positioning member 6 is further included, the first die 1 includes an upper die 11 and a stripper plate 12 oppositely arranged along the vertical direction, one end of the second positioning member 6 is connected to the stripper plate 12, and the other end of the second positioning member 6 can be penetrated into a second positioning hole of the material belt 200.

Among them, the upper die 11 can move along the vertical direction relative to the stripper plate 12, and the upper die 11 can also move along the vertical direction together with the stripper plate 12.

[0065] As shown in Figure 3 , one end of the second positioning member 6 can be connected to the stripper plate 12, and the other end of the second positioning member 6 can be connected to the second positioning hole of the material belt 200. In the process that the upper die 11 and the stripper plate 12 move along the vertical direction together and approach the bearing part 23, the other end of the second positioning member 6 can be penetrated into the second positioning hole of the material belt 200 and connected with the material belt 200, so as to position the material belt 200, to facilitate subsequent reliable blanking. Among them, the second positioning hole is usually arranged close to the product 2001 to be blanked, so as to improve the blanking accuracy.

[0066] Optionally, a floating part 7 is further included, which is arranged on the second die 2 and can drive the material belt 200 to move along the vertical direction.

[0067] As shown in Figure 2 , the floating part 7 is arranged on the second die 2 and can float along the vertical direction on the second die 2, so as to drive the material belt 200 carried thereby to move together for vertical position adjustment, so as to place the product 2001 on the material belt 200 on the bearing part 23, to facilitate subsequent blanking process.

[0068] Optionally, the number of floating parts 7 is multiple, and the multiple floating parts 7 are arranged on the second die 2 at intervals, so as to use the multiple floating parts 7 to carry different parts of the material belt 200, which helps to improve the reliability and controllability of the movement of the material belt 200.

[0071] Before punching, under the driving of the upper die 11, the limiting column 71 can drive the tape 200 carried thereby to descend in the vertical direction through the floating block 72 until the product 2001 on the tape 200 is on the carrying part 23 for the subsequent punching process, and meanwhile, the deformation of the tape 200 caused by the direct contact of the stripper plate 12 with the tape 200 can be avoided, which helps to improve the punching reliability; after the punching is completed, under the driving of the upper die 11, the limiting column 71 can drive the tape 200 carried thereby to ascend in the vertical direction through the floating block 72 until the product 2001 on the tape 200 leaves the carrying part 23 for the replacement of the product 2001.

[0073] As shown, Figure 5 one end of the second spring 73 abuts against the limiting column 71, and the other end of the second spring 73 abuts against the upper die 11, so that when the upper die 11 moves downward, the upper die 11 can compress the second spring 73, and the second spring 73 can elastically deform to buffer part of the pressure, so that the upper die 11 can drive the tape 200 carried thereby to slowly and smoothly descend in the vertical direction through the limiting column 71 and the floating block 72 to avoid the abnormality of the tape 200 caused by the sudden change of the pressure; after the punching is completed and the downward pressure applied to the upper die 11 is removed, the second spring 73 can elastically reset and drive the tape 200 carried thereby to ascend in the vertical direction to the initial position through the floating block 72, which can also save the driving force and help to reduce the overall energy consumption of the punching device 100.

[0074] As shown, Figure 2 the floating block 72 can comprise a first part and a second part (not shown in the figure) connected by bending, the first part is arranged on the second die 2 and connected with the limiting column 71, and the second part extends into the tape passage and can carry the tape 200. Among them, the second part can be provided with a carrying table for carrying the bottom of the tape 200.

[0075] In one embodiment, the first part can be designed in an I-shaped structure to facilitate the connection of the upper limiting column 71 and improve the structural stability of the floating block 72.

[0076] In one embodiment, the second part can be designed in an L-shaped structure, one side wall of the L-shaped structure is connected to the first part, and the other side wall of the L-shaped structure is used to bear the bottom of the material belt 200.

[0077] Optionally, a limiting piece 8 is further included, one end of the limiting piece 8 is connected to the first mold 1, and the other end of the limiting piece 8 abuts against the material receiving piece 4.

[0078] As shown in Figure 2 and Figure 3 , one end of the limiting piece 8 is connected to the first mold 1, so that the first mold 1 can drive the limiting piece 8 to move vertically until the other end of the limiting piece 8 abuts against the material receiving piece 4, at this time, the limiting piece 8 can push the material receiving piece 4 to move vertically downward to the avoiding position, so as to avoid the material receiving piece 4 from pressing the product 2001 during the punching process, and also avoid the interference of the material receiving piece 4 to the punching process; after the punching is completed, the first mold 1 can drive the material receiving piece 4 to move vertically upward to the receiving position through the limiting piece 8, so as to facilitate the product 2001 after punching to fall into the material receiving piece 4.

[0079] Among them, the connection position of the limiting piece 8 and the first mold 1 in the vertical direction is lower than the connection position of the limiting piece 8 and the cutting tool 3, so that during the vertical downward movement of the first mold 1, the limiting piece 8 can first contact the material receiving piece 4 and press downward to the avoiding position, and then the cutting tool 3 contacts the product 2001 and performs punching, so as to ensure the safety of the punching process.

[0080] In one embodiment, the limiting piece 8 can be long handle-shaped to facilitate the connection with the first mold 1. The end thereof is directed towards the material receiving piece 4 to abut against or abut the material receiving piece 4.

[0081] In one embodiment, a third spring can be arranged between the material receiving piece 4 and the bearing surface of the bearing part 23, so that during the process that the limiting piece 8 pushes the material receiving piece 4 to move vertically downward to the avoiding position, the third spring can be constantly compressed, and after the pressure of the limiting piece 8 is removed, the third spring can be elastically reset and drive the material receiving piece 4 to move vertically upward to the receiving position, at this time, only the other end of the limiting piece 8 needs to abut against the material receiving piece 4, without the need for connection, and the assembly process of the punching device 100 can be simplified.

[0082] Optionally, the first mold 1 includes an upper mold 11 and a stripper 12 arranged opposite in the vertical direction, the limiting piece 8 is connected to the stripper 12, and the cutting tool 3 is connected to the upper mold 11.

[0083] AsFigure 1 As shown, the first mold 1 may include an upper mold 11 and a stripper plate 12 arranged opposite each other along the vertical direction. The upper mold 11 may include an upper mold base, an upper pad, and an upper clamping plate. The upper pad is clamped between the upper mold base and the upper clamping plate. The upper mold 11 and the stripper plate 12 may be connected by guide posts. The upper mold 11 may move vertically relative to the stripper plate 12, and the upper mold 11 may also move vertically together with the stripper plate 12.

[0084] like Figures 1 to 3 As shown, the limiting member 8 can be connected to the stripper plate 12, so that the stripper plate 12 can drive the limiting member 8 to move vertically until the other end of the limiting member 8 abuts against the receiving member 4. At this time, the limiting member 8 can push the receiving member 4 vertically downward to the avoidance position, thereby avoiding the receiving member 4 from crushing the product 2001 during the punching process, and also avoiding the receiving member 4 from interfering with the punching process. After the punching is completed, the stripper plate 12 can drive the receiving member 4 vertically upward to the receiving position through the limiting member 8, so that the punched product 2001 can fall into the receiving member 4.

[0085] The device is configured such that, in the vertical direction, the limiting member 8 is connected to the stripper plate 12 and the cutting blade 3 is connected to the upper mold 11. This allows the limiting member 8 to contact the receiving member 4 and press down to the avoidance position before the cutting blade 3 contacts the product 2001 and performs punching, thus ensuring the safety of the punching process.

[0086] Optionally, the receiving component 4 includes a third part 41 and a fourth part 42 that are bent and connected, the third part 41 being disposed on the bearing part 23, and the fourth part 42 extending to the outside of the bearing part 23; And / or, the receiving part 4 has a suction nozzle connected to the carrier part 23.

[0087] like Figure 3 As shown, the included angle between the third part 41 and the fourth part 42 is adapted to the structure of the support part 23, such that the third part 41 is located on the support surface of the support part 23, while the fourth part 42 can extend to the outside of the support part 23. In this way, the punched product 2001 can fall into the third part 41 and enter the interior of the receiving part 4 through the fourth part 42 for subsequent recycling.

[0088] During the punching process, the cut-off product 2001 will fall smoothly into the receiving component 4 under its own weight or guided by the receiving component 4, and will be collected into a designated container through the guiding structure (such as an inclined slide) within the receiving component 4. This design eliminates the need for manual collection of product 2001, reduces downtime during production, enables the production line to operate continuously and stably, and thus improves overall production efficiency.

[0089] In one embodiment, a suction nozzle can also be provided in the receiving part 4. The suction nozzle can use negative pressure to adsorb the product 2001 that has fallen after the punching is completed, and guide the product 2001 to fall into a predetermined position in the receiving part 4.

[0090] The present invention also provides a conveying system, including a material belt 200 and the aforementioned punching device 100, wherein the receiving member 4 is detachably connected to the bearing portion 23 along the vertical direction. Thus, the cut product 2001 can fall from the bearing portion 23 into the receiving member 4 below under its own weight, and slide along the inclined surface of the receiving member 4 for automatic collection.

[0091] Depending on the product 2001 being cut, different receiving parts 4 can be replaced, thereby simplifying the receiving process.

[0092] Optionally, it also includes a product seat 300, wherein the receiving member 4 is movable between the punching device 100 and the product seat 300.

[0093] like Figure 6 As shown, the cut product 2001, under its own weight, falls from the supporting part 23 into the receiving part 4 below, sliding along the inclined surface of the receiving part 4 for automatic collection. Afterwards, the receiving part 4 can move laterally to the suction area, where the suction cups inside the receiving part 4 can pick up the product 2001 and place it into the product holder 300, thus achieving conveying of the product holder 300. In this way, the receiving part 4 only performs linear movement without flipping, which helps save punching time and avoids abnormalities such as damage to the product 2001 caused by the flipping process.
