Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of punching processing, in particular to a blanking and punching compound die. Background Art
[0002] Punching refers to placing the raw material on a die, and then using a hydraulic device to drive the punch head down to punch holes on the surface of the raw material. A compound die usually refers to a die structure in which the punch press can complete multiple processes such as blanking and punching in one stroke, and is mostly used in the field of metal manufacturing technology.
[0003] Application number 202223035766.2 discloses a cold stamping, punching, and blanking composite die, comprising a static die base and a dynamic die base. A forming static die is disposed on the top of the static die base, the dynamic die base is located above the forming static die, and a forming dynamic die is fixedly mounted on the bottom of the dynamic die base. Two sets of support plates are fixedly mounted on the top of the static die base, and a forming static die is fixedly mounted on the top of the support plates. A punching hole is provided in the middle of the forming static die, and a punching rod that cooperates with the punching hole and a guide column that cooperates with the forming static die are fixedly mounted on the bottom of the forming dynamic die. In this cold stamping, punching, and blanking composite die, the waste material after punching falls along the punching hole into the top of the blanking plate, thereby collecting the waste material. At the same time, the waste material can slide outward along the inclined surface of the top of the blanking plate to prevent waste material from accumulating inside the die.
[0004] Although this technical solution facilitates the discharge of blanking materials, after a period of use, the structure is easily damaged by the long-term impact of falling waste, thereby increasing the resistance of the waste to sliding out. As time goes by, it is easy to cause the blanking plate to break, causing the waste to pass directly through the blanking plate and be difficult to be discharged by the blanking plate. Utility Model Content
[0005] Based on this, the purpose of the present invention is to provide a blanking and punching compound die to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blanking and punching compound die, comprising a fixed die and a blanking plate, a baffle connected to the top of the blanking plate, and a limiting plate connected to one side of the baffle, a magnetic plate fixed to the top of the limiting plate, a connecting shaft connected between the limiting plate and the baffle, and a nut sleeved on the outside of the connecting shaft.
[0007] By adopting the above technical solution, the blanking plate is shielded by the baffle to prevent the blanking plate from being damaged by falling waste. When the baffle is damaged, the limit plate is rotated to end the limitation of the baffle, and then the baffle is pushed to the upper right direction so that the baffle can be separated from the blanking plate, thereby facilitating disassembly; during assembly, the baffle is placed in the upper right corner of the blanking plate, and then the baffle is pulled toward the lower left, and then the limit plate is rotated to make the magnetic plate and the blanking plate engage to limit the limit plate, thereby limiting the baffle. If the limit plate is not damaged, the limitation of the connecting shaft can be ended by unscrewing the nut, and then the connecting shaft can be pulled out from the baffle and the limit plate, thereby completing the disassembly of the limit plate, and then the limit plate can be installed on other baffles to reduce resource waste.
[0008] Furthermore, the cross section of the baffle is in the shape of an inverted "J", and the limiting plate is in the shape of an "L".
[0009] By adopting the above technical solution, the limit plate is rotated to end the limitation of the baffle, and then the baffle is pushed to the upper right direction so that the baffle can be separated from the blanking plate. During assembly, the baffle is placed in the upper right corner of the blanking plate, and then the baffle is pulled toward the lower left, and then the limit plate is rotated to limit the baffle.
[0010] Furthermore, the baffle is detachably connected to the blanking plate, and the limiting plate abuts against the blanking plate.
[0011] By adopting the above technical solution, when the baffle is damaged, the limiting plate is rotated to end the limiting of the baffle, so that the baffle can be separated from the blanking plate.
[0012] Furthermore, the limiting plate is rotatably connected to the baffle via a connecting shaft.
[0013] By adopting the above technical solution, during assembly, the baffle is placed in the upper right corner of the blanking plate, then the baffle is pulled toward the lower left, and then the limit plate is rotated so that the magnetic plate and the blanking plate are attracted to limit the limit plate, thereby limiting the baffle.
[0014] Furthermore, two nuts are provided, and both nuts are threadedly connected to the connecting shaft.
[0015] By adopting the above technical solution, if the limit plate is not damaged, the limiting of the connecting shaft can be ended by unscrewing the nut, and then the connecting shaft can be pulled out from the baffle and the limit plate to complete the disassembly of the limit plate. The limit plate can then be installed on other baffles to reduce resource waste.
[0016] Furthermore, a blanking hole is opened on the top of the fixed mold, a blanking seat is connected to the bottom of the fixed mold, and a spring and a telescopic rod are respectively connected to the bottom of the blanking seat, and the blanking plate is connected to the spring and the top of the telescopic rod.
[0017] By adopting the above technical solution, part of the impact force after the waste falls will act on the spring, causing the spring to deform and prompt the blanking plate to swing back and forth for a period of time, thereby reducing the occurrence of waste staying in the blanking seat.
[0018] Furthermore, the blanking hole is located above the blanking plate, and the blanking plate is arranged at an angle.
[0019] By adopting the above technical solution, after the material is punched, the waste generated by the punching passes through the blanking hole and falls onto the baffle, and then the slope generated by the inclination of the blanking plate guides the waste out.
[0020] Furthermore, a buffer pad is fixed on the top of the baffle, and the buffer pad is made of rubber material.
[0021] By adopting the above technical solution, the impact force of the waste falling is buffered by the provision of the buffer pad, thereby reducing the impact force on the baffle and extending the service life of the baffle.
[0022] In summary, the present invention has the following beneficial effects:
[0023] 1. The utility model uses the arrangement of a baffle, a limit plate, a connecting shaft and a magnetic plate to shield the blanking plate through the baffle to prevent the blanking plate from being damaged when the waste falls. When the baffle is damaged, the limit plate is rotated to end the limit of the baffle, and then the baffle is pushed to the upper right direction to separate the baffle from the blanking plate, thereby facilitating disassembly. When assembling, the baffle is placed in the upper right corner of the blanking plate, and then the baffle is pulled toward the lower left, and then the limit plate is rotated to make the magnetic plate and the blanking plate engage to limit the limit plate, thereby limiting the baffle and preventing the blanking plate from being damaged.
[0024] 2. The utility model is provided with a connecting shaft and a nut. If the limit plate is not damaged, the limit of the connecting shaft can be ended by unscrewing the nut, and then the connecting shaft can be pulled out from the baffle and the limit plate to complete the disassembly of the limit plate. The limit plate can then be installed on other baffles to reduce resource waste; it is convenient to recycle the non-damaged structure, thereby reducing resource waste and saving costs.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0031] The following describes an embodiment of the present invention based on its overall structure.
[0032] Example 1:
[0033] A blanking and punching compound die, such as Figures 1-4 As shown, it includes a fixed mold 1 and a blanking plate 3, and a baffle 6 is connected to the top of the blanking plate 3, which blocks the blanking plate 3 through the baffle 6 to prevent the blanking plate 3 from being damaged when the waste falls; the cross section of the baffle 6 is in an inverted "J" shape, and the baffle 6 is detachably connected to the blanking plate 3. One side of the baffle 6 is connected to a limit plate 7, and the limit plate 7 is in an "L" shape. The limit plate 7 abuts against the blanking plate 3, and the limit plate 7 is rotatably connected to the baffle 6 through a connecting shaft 8. The limit plate 7 is rotated to end the limit of the baffle 6, and then the baffle 6 is pushed to the upper right direction so that the baffle 6 can be separated from the blanking plate 3, thereby facilitating disassembly; the top of the limit plate 7 A magnetic plate 10 is fixed on the part, and the limit plate 7 is rotated so that the magnetic plate 10 and the blanking plate 3 are attracted to limit the limit plate 7, thereby limiting the baffle 6; a connecting shaft 8 is connected between the limit plate 7 and the baffle 6, and a nut 9 is sleeved on the outside of the connecting shaft 8. There are two nuts 9, and both nuts 9 are threadedly connected to the connecting shaft 8. If the limit plate 7 is not damaged, the limit of the connecting shaft 8 can be ended by unscrewing the nut 9, and then the connecting shaft 8 can be pulled out from the baffle 6 and the limit plate 7, thereby completing the disassembly of the limit plate 7, and then the limit plate 7 can be installed on other baffles 6 to reduce resource waste.
[0034] See Figure 1 and Figure 2 In the above embodiment, a blanking hole 2 is opened on the top of the fixed mold 1. After the raw material is punched, the waste generated by punching falls through the blanking hole 2; the bottom of the fixed mold 1 is connected to a blanking seat 12, and the bottom of the blanking seat 12 is respectively connected to a spring 4 and a telescopic rod 5, and a blanking plate 3 is connected to the top of the spring 4 and the telescopic rod 5. The blanking hole 2 is located above the blanking plate 3, and the blanking plate 3 is tilted. After the waste falls, part of the impact force will act on the spring 4, causing the spring 4 to deform and prompting the blanking plate 3 to swing back and forth up and down for a period of time, thereby reducing the occurrence of waste staying in the blanking seat 12.
[0035] Example 2:
[0036] On the basis of the above embodiment 1, in order to reduce the damage to the baffle 6 caused by falling waste, the following settings are now adopted.
[0037] See Figure 2 and Figure 4 In the above embodiment, a buffer pad 11 is fixed on the top of the baffle 6. The buffer pad 11 is made of rubber material. The buffer pad 11 is set to buffer the impact force when the waste falls, reduce the impact force on the baffle 6, and extend the service life of the baffle 6.
[0038] The implementation principle of the utility model is as follows: first, after the raw material is punched, the waste material generated by the punching passes through the blanking hole 2 and falls onto the buffer pad 11. The buffer pad 11 is provided to cushion the impact force of the waste material when it falls, reducing the impact force on the baffle 6 to extend the service life of the baffle 6. Then, the slope generated by the inclination of the blanking plate 3 guides the waste material out, and part of the impact force after the waste material falls will act on the spring 4, causing the spring 4 to deform and prompt the blanking plate 3 to rock back and forth for a period of time, thereby reducing the phenomenon of waste material staying in the blanking seat 12.
[0039] The blanking plate 3 is shielded by the baffle 6 to prevent the waste from hitting the blanking plate 3 when falling. When the baffle 6 is damaged, the limit plate 7 is rotated to end the limit of the baffle 6, and then the baffle 6 is pushed to the upper right direction so that the baffle 6 can be separated from the blanking plate 3, thereby facilitating disassembly. If the limit plate 7 is not damaged, the limit of the connecting shaft 8 can be ended by unscrewing the nut 9, and then the connecting shaft 8 can be pulled out from the baffle 6 and the limit plate 7, thereby completing the disassembly of the limit plate 7, and then the limit plate 7 can be installed on other baffles 6 to reduce resource waste.
[0040] During assembly, place the baffle 6 at the upper right corner of the blanking plate 3, then pull the baffle 6 toward the lower left, and then rotate the limit plate 7 so that the magnetic plate 10 and the blanking plate 3 are attracted to limit the limit plate 7, thereby limiting the baffle 6.
[0041] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
