Description

Technical Field

[0001] This application relates to the field of stamping technology, and more specifically, to a multi-station stamping forming die. Background Technology

[0002] Stamping is a forming process that uses a press and a die to apply external force to sheet metal, strip, tube, and profile, causing plastic deformation or separation to obtain workpieces (stamped parts) of the required shape and size. For example, Chinese Patent CN202321584948.7 discloses a multi-station automotive parts stamping die, which includes a housing and a material feed chute. The housing has several material feed chutes on its upper part, and a material drop chute is provided on the outside of the material feed chute. A material blocking plate is provided below the material drop chute, and telescopic rods are fixedly connected to both sides of the material blocking plate. The telescopic rods have plate grooves on their outside, and a material storage box is provided below the material blocking plate. Compared with existing ordinary stamping dies, this multi-station automotive parts stamping die, after completing one stamping operation, has a telescopic rod that drives the material blocking plate to move outward and fit into the plate groove, allowing the product inside the material passage to slide from the drop groove into the storage box below. This enables the operator to directly remove the product, which is safer than the operator directly touching the inside of the material passage to remove the material. It also prevents the material removal process from affecting the die's processing progress, thus improving processing speed and applicability.

[0003] However, this existing technology has certain limitations in its use. Operators need to stop the machine before they can remove the storage box. If it is removed while the equipment is running, the product will fall into the inner cavity of the box and needs to be manually collected again, which affects the continuity of production and the overall work efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a multi-station stamping die that can solve the technical problem in the prior art where operators need to stop the machine before they can remove the storage box. If the box is removed while the equipment is running, the product will fall into the inner cavity of the box and needs to be manually collected again, which affects the continuity of production and the overall work efficiency.

[0005] This application provides a multi-station stamping die, including a housing and a stamping assembly disposed on the upper end of the housing. A material feed groove is provided on the top of the housing, and a material discharge groove is connected to the lower part of the material feed groove. An installation groove is connected to the side of the material discharge groove, and a material storage groove is connected to the lower part of the material discharge groove. A material blocking plate is movably disposed in the material discharge groove, and a first cylinder is fixedly disposed in the installation groove. The piston rod of the first cylinder is connected to the material blocking plate and drives the material blocking plate to move to open or close the material discharge groove. Two material storage boxes are stacked in the material storage groove.

[0006] The storage trough is equipped with a support assembly located between the two storage boxes. The support assembly includes a support plate and an elastic element. A first clearance groove is provided on the side of the storage trough. One end of the support plate is hinged in the first clearance groove, and the other end of the support plate can rotate to the first clearance groove or the storage trough. The elastic element is pre-pressed between the side wall of the first clearance groove and the upper end of the support plate. The storage box can be placed on top of the support plate.

[0007] The support components are arranged in pairs, with at least one pair, and each pair of support components is symmetrically arranged on both sides of the storage tank.

[0008] A connecting rope is provided between the side wall of the first clearance groove and the upper end of the support plate.

[0009] The storage tank is equipped with a lifting plate, and the storage box can be placed on top of the lifting plate. A second cylinder is fixedly installed at the lower end of the box. The piston rod of the second cylinder is connected to the lifting plate and drives the lifting plate to move up and down.

[0010] The storage trough has a second clearance groove connected to its side, and a limit rod is movably installed in the second clearance groove. The outer wall of the storage box has a limit groove, and the side of the box is provided with a transmission assembly. The transmission assembly is used to drive the limit rod to move into the limit groove and slide in a limited manner with the limit groove.

[0011] The transmission assembly includes a screw, a first handle, and a slide rod. The screw is threaded through the housing, one end of the screw is rotatably connected to the limiting rod via a bearing, and the other end of the screw is fixedly connected to the first handle. The slide rod slides through the housing and is fixedly connected to the limiting rod.

[0012] The storage box is equipped with a second handle.

[0013] The stamping assembly includes a fixed rod, a top plate, a hydraulic cylinder, a fixed plate, and a stamping head. The fixed rod is fixedly installed on the upper end of the housing, the top plate is fixedly installed on the upper end of the fixed rod, the hydraulic cylinder is fixedly installed on the lower end of the top plate, the piston rod of the hydraulic cylinder is connected to the fixed plate and drives the fixed plate to move up and down, and the stamping head is installed on the lower end of the fixed plate and is used in conjunction with the material passage.

[0014] The stamping head is provided in multiple forms.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a multi-station stamping forming die. In use, stamping operations are performed through stamping components. After one stamping operation is completed, the first cylinder is activated to drive the material blocking plate to move to open the material discharge groove. The formed product inside the material discharge groove can then fall from the material discharge groove into the storage groove below and be received by the storage box. When the upper storage box is full, it can be removed, and the lower storage box can continue to receive material. After the full storage box is emptied, the storage box that is currently being filled is raised close to the material discharge groove, and the empty storage box is placed back into the storage groove to form a stack, ready for filling again. The stacking design of the two storage boxes constitutes a "one-in-use, one-out-of-use" system, which allows the replacement of a full storage box without stopping the machine, avoiding interruption of the stamping process due to manual intervention, effectively reducing production downtime, ensuring production continuity, and improving production efficiency.

[0034] It should be noted that all electrical components appearing in this application are connected to an external main controller and mains power. The main controller can be a conventional known device such as a computer for control. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets and welding that are mature in the prior art. Furthermore, the machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. These are prior art known to those skilled in the art and will not be described in detail here.

[0035] like Figures 1 to 4 As shown, this application embodiment provides a multi-station stamping forming mold, including a box body 1 and a stamping assembly 2 disposed on the upper end of the box body 1. A material passage trough 11 is opened on the top of the box body 1. A material drop trough 12 is connected to the lower part of the material passage trough 11. An installation groove 13 is connected to the side of the material drop trough 12. A storage groove 14 is connected to the lower part of the material drop trough 12. A material blocking plate 15 is movably disposed in the material drop trough 12. A first cylinder 16 is fixedly disposed in the installation groove 13. The piston rod of the first cylinder 16 is connected to the material blocking plate 15 and drives the material blocking plate 15 to move to open or close the material drop trough 12. Two storage boxes 3 are stacked in the storage groove 14.

[0036] In use, the stamping operation is performed by the stamping component 2. After one stamping operation is completed, the first cylinder 16 is activated to drive the material blocking plate 15 to move to open the material drop chute 12. The formed product inside the material passage chute 11 can fall from the material drop chute 12 into the storage chute 14 below and be received by the storage box 3. When the storage box 3 above is full, it can be taken out and the storage box 3 below can continue to receive material. After emptying the storage box 3 full of product, the storage box 3 that is currently being filled is raised close to the material drop chute 12, and the empty storage box 3 is put into the storage chute 14 to form a stack again, ready for filling again.

[0037] The stacked design of the dual storage boxes 3 constitutes a "one-in-use, one-out-of-use" system, which allows for the replacement of a full storage box 3 without stopping the machine, avoiding interruptions to the stamping process due to manual intervention, effectively reducing production downtime, ensuring production continuity, and improving production efficiency.

[0038] like Figures 1 to 4 As shown, in this embodiment, a support component 4 is provided in the storage tank 14. The support component 4 is located between two storage boxes 3, and the support component 4 includes a support plate 41 and an elastic member 42. A first clearance groove 17 is provided on the side of the storage tank 14. One end of the support plate 41 is hinged in the first clearance groove 17, and the other end of the support plate 41 can be rotated into the first clearance groove 17 or into the storage tank 14. The elastic member 42 is pre-pressed between the side wall of the first clearance groove 17 and the upper end of the support plate 41. The storage box 3 can be placed on the top of the support plate 41.

[0039] The elastic element 42 is a spring. When the storage box 3 is raised close to the discharge trough 12, the top of the storage box 3 will press against the support plate 41, causing the support plate 41 to rotate upward against the force of the elastic element 42 and retract into the first clearance groove 17, thereby making room so that the storage box 3 can be raised smoothly. At this time, the elastic element 42 is compressed. When the storage box 3 is raised to the point where it stops pressing the support plate 41, under the elastic force of the elastic element 42, the support plate 41 returns to its original position, remains horizontal, and extends into the storage trough 14, forming a reliable support platform to support the storage box 3. This mold provides automatic and reliable support by setting the support component 4. The elastic element 42 ensures that the support plate 41 always has the tendency to support the storage box 3, ensuring its stability and reliability during production. Moreover, it is convenient to pick up and put down. When replacing the storage box 3, no additional operation is required. It can be lifted directly, and the support plate 41 automatically avoids the gap. The operation is simple and fast, shortening the replacement time.

[0040] like Figures 1 to 4 As shown, in this embodiment, the support components 4 are arranged in pairs, with at least one pair. Each pair of support components 4 is symmetrically arranged on both sides of the storage tank 14. The symmetrical arrangement of the support components 4 ensures that the storage box 3 is subjected to uniform force, avoiding the jamming, tilting or tipping problems that may be caused by unilateral support, ensuring the stability of the operation process. Moreover, multi-point support can support heavier products and storage boxes 3, improving the applicability and reliability of the mold.

[0041] like Figures 2 to 4 As shown, in this embodiment, a connecting rope 18 is provided between the side wall of the first clearance groove 17 and the upper end of the support plate 41; when the support plate 41 rotates downward under the action of elasticity, the connecting rope 18 will be straightened, thereby limiting the maximum rotation angle of the support plate 41 and preventing it from overturning, thus playing a protective role.

[0042] like Figures 1 to 3 As shown, in this embodiment, a lifting plate 19 is movably arranged inside the storage tank 14, and the storage box 3 can be placed on the top of the lifting plate 19. A second cylinder 110 is fixedly arranged at the lower end of the box body 1. The piston rod of the second cylinder 110 is connected to the lifting plate 19 and drives the lifting plate 19 to move up and down.

[0043] When it is necessary to lift the storage box 3, the second cylinder 110 is activated to drive the lifting plate 19 to rise. The storage box 3 located at the top of the lifting plate 19 rises accordingly, thereby lifting the storage box 3 close to the material drop chute 12. The mold can automatically lift the storage box 3 to a suitable receiving height without manual lifting, reducing the labor intensity of operators and improving operating comfort and safety.

[0044] like Figures 1 to 4 As shown, in this embodiment, a second clearance groove 111 is provided on the side of the storage tank 14, and a limit rod 112 is movably provided in the second clearance groove 111. A limit groove 31 is opened on the outer wall of the storage box 3, and a transmission assembly 5 is provided on the side of the box body 1. The transmission assembly 5 is used to drive the limit rod 112 to move into the limit groove 31 and slide in a limited manner with the limit groove 31.

[0045] When the storage box 3 needs to be lifted, the transmission assembly 5 first drives the limiting rod 112 to move into the limiting groove 31, so that the storage box 3 can only rise in a straight line along the limiting rod 112. The cooperation between the limiting rod 112 and the limiting groove 31 plays a guiding and limiting role for the storage box 3, which can ensure the positioning accuracy of the lifting of the storage box 3, and also effectively ensure the stability of the lifting process of the storage box 3, while preventing the storage box 3 from accidentally sliding out or tipping over. When the storage box 3 needs to be removed, the transmission assembly 5 drives the limiting rod 112 to move into the retracted second clearance groove 111, thereby making room so that the storage box 3 can be smoothly removed.

[0046] like Figures 1 to 4 As shown, in this embodiment, the transmission assembly 5 includes a screw 51, a first handle 52, and a slide rod 53. The screw 51 is threaded through the housing 1. One end of the screw 51 is rotatably connected to the limiting rod 112 through a bearing, and the other end of the screw 51 is fixedly connected to the first handle 52. The slide rod 53 slides through the housing 1 and is fixedly connected to the limiting rod 112.

[0047] When the limiting rod 112 needs to be moved, the first handle 52 is turned to drive the screw 51 to rotate, and the screw 51 drives the limiting rod 112 to move. The mechanical locking provides a reliable fixing force, effectively preventing the storage box 3 from moving and ensuring the stability of the collection process. Moreover, the threaded drive is easy to control, requires little effort to operate, and is self-locking, maintaining the locked state without the need for continuous force. The sliding rod 53, in cooperation with the box 1, guides and limits the limiting rod 112, ensuring that the limiting rod 112 accurately inserts into or exits the limiting groove 31.

[0048] like Figure 1 and 4 As shown, in this embodiment, a second handle 32 is fixedly provided on the storage box 3; the second handle 32 makes it easier for the operator to apply force to remove the storage box 3, thus improving the ease of use.

[0049] like Figure 1 As shown, in this embodiment, the stamping assembly 2 includes a fixing rod 21, a top plate 22, a hydraulic cylinder 23, a fixing plate 24, and a stamping head 25. The fixing rod 21 is fixedly installed on the upper end of the housing 1, the top plate 22 is fixedly installed on the upper end of the fixing rod 21, the hydraulic cylinder 23 is fixedly installed on the lower end of the top plate 22, the piston rod of the hydraulic cylinder 23 is connected to the fixing plate 24 and drives the fixing plate 24 to move up and down, the stamping head 25 is installed on the lower end of the fixing plate 24, and the stamping head 25 is used in conjunction with the material feed chute 11.

[0050] During the stamping operation, the hydraulic cylinder 23 is activated to drive the fixed plate 24 to move downwards. The stamping head 25 moves downwards along with the fixed plate 24 and cooperates with the material feed groove 11 to complete the stamping and forming of the sheet metal.

[0051] like Figure 1 As shown, in this embodiment, multiple stamping heads 25 are provided; multiple stamping heads 25 allow multiple products to be produced simultaneously in one stamping stroke, realizing multi-station stamping and forming operations and increasing output per unit time.

[0052] Working principle: When the multi-station stamping forming mold provided in this application is used, the stamping component 2 performs the stamping operation. After completing one stamping operation, the first cylinder 16 is activated to drive the material blocking plate 15 to move to open the material dropping groove 12. The formed product inside the material passing groove 11 can fall from the material dropping groove 12 into the storage groove 14 below and be received by the storage box 3.

[0053] Once the upper storage box 3 is full, it can be removed, and the lower storage box 3 can be used to continue receiving material. After emptying the full storage box 3, turn the first handle 52 to drive the screw 51 to rotate. The screw 51 drives the limit rod 112 to move into the limit groove 31, so that the storage box 3 can only rise in a straight line along the limit rod 112. Then, the second cylinder 110 is activated to drive the lifting plate 19 to rise. The storage box 3 located at the top of the lifting plate 19 rises accordingly, thereby lifting the storage box 3, which is currently being filled, closer to the discharge chute 12 for material storage. The top of the box 3 will press against the support plate 41, causing the support plate 41 to rotate upward against the force of the elastic member 42 and retract into the first clearance groove 17, thereby making space so that the storage box 3 can be lifted smoothly. At this time, the elastic member 42 is squeezed. When the storage box 3 is lifted to the point where it stops pressing the support plate 41, under the elastic force of the elastic member 42, the support plate 41 returns to its original position, remains horizontal, and extends into the storage tank 14, forming a reliable support platform to support the storage box 3. Then, the empty storage box 3 is placed into the storage tank 14 to form a stack again, ready for refilling.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
