Description

Technical Field

[0001] This utility model relates to the field of metal stamping technology, specifically a metal stamping forming device. Background Technology

[0002] Hardware parts refer to products made from metals such as gold, silver, copper, iron, and tin through processing and casting. In the manufacturing process of hardware parts, stamping is generally used. Stamping is a forming process that uses a press and mold to apply external force to sheet metal, strip, tube and profile, causing plastic deformation or separation, thereby obtaining stamped parts of the required shape and size. It is frequently used in the production and processing of hardware parts.

[0003] In traditional stamping forming equipment, workers need to place the workpieces to be stamped one by one into the bottom mold. Then the top mold moves down and works with the bottom mold to complete the stamping of the workpieces. Since multiple hardware workpieces are involved, workers need to manually and accurately place them in the designated positions. This repetitive action greatly increases the labor intensity of workers. At the same time, workers' hands are easily injured by the stamping forming equipment during frequent operation, making the stamping forming equipment a safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a metal stamping forming device. This solves the problem that in traditional stamping forming devices, operators must place the workpieces to be stamped one by one into the bottom mold, and then the top mold moves downwards to cooperate with the bottom mold to complete the stamping of the workpieces. Since multiple metal workpieces are involved, operators need to manually and precisely place them in designated positions. This repetitive action greatly increases the labor intensity of the operators. At the same time, the operators' hands are easily injured by the stamping forming device during frequent operation, creating a safety hazard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal stamping forming device, comprising a device frame, a worktable fixedly connected to the bottom of the device frame, support legs fixedly connected to the bottom of the worktable, a control panel fixedly connected to the top of the worktable, a storage box installed inside the device frame, and a feeding mechanism provided in the storage box, the feeding mechanism comprising: two limiting plates, both fixedly connected to the upper inner wall of the storage box; a second electric push rod rotatably connected to one end of the two limiting plates and electrically connected to the control panel via a wire; a rotating block rotatably connected to the output end of the second electric push rod and rotatably connected to the inner wall of the storage box away from the limiting plates via a bearing; and two baffles, both slidably engaged in the groove of the rotating block and inserted into the inner wall of the storage box; wherein, when the second electric push rod is working, it drives the two baffles to move up and down alternately through the rotating block, restricting the internal pipes of the storage box from being discharged outwards in sequence to complete the feeding.

[0006] Preferably, a collection box is placed inside the support leg on the side away from the control panel, and a hopper is fixedly connected to the inner wall of the workbench on the side away from the control panel, with the hopper extending through the bottom of the workbench.

[0007] Preferably, a bottom mold is fixedly connected to the top of the workbench by bolts, and a top mold is provided on the top of the bottom mold.

[0008] Preferably, the internal structure of the device frame includes a moving mechanism comprising: a servo motor, fixedly connected to the outer wall of the device frame near the control panel and electrically connected to the control panel via a wire; a lead screw, rotatably connected to the inner wall of the device frame via a bearing and fixedly connected to the output end of the servo motor; a sliding plate, threadedly connected to the outer wall of the lead screw near the servo motor and slidably engaged with the inner wall of the device frame; two first electric push rods, both fixedly connected to the bottom of the sliding plate and electrically connected to the control panel via wires; a base plate, fixedly connected to the output ends of the two first electric push rods and fixedly connected to the top of the top mold via bolts; and an electromagnet, fixedly connected to the inner wall of the base plate and electrically connected to the control panel via a wire. When the servo motor operates, it drives the sliding plate to move via the lead screw, and the sliding plate drives the top mold below the base plate to a designated position via the two first electric push rods.

[0009] Preferably, the bottom of the skateboard is fixedly connected to two curved plates.

[0010] Beneficial effects

[0011] This utility model provides a metal stamping forming device. It has the following advantages: This metal stamping forming device, through a feeding mechanism, sequentially places metal tubes above the bottom mold. During the stamping process, the metal tubes do not require frequent handling by operators, reducing the labor intensity of workers. Simultaneously, the workers' hands do not come into contact with the stamping forming device, preventing accidental injury to their hands and solving the safety hazard problem associated with stamping forming devices.

[0012] The moving mechanism drives the top and bottom molds to close, completing the stamping process of the metal pipe. The moving mechanism then moves the processed metal pipe to the top of the hopper, where the electromagnet stops working. At the same time, the formed metal pipe is restricted by the bending plate and falls downwards into the collection box, facilitating its collection. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] In the traditional stamping forming equipment, the operator needs to place the workpieces to be stamped one by one into the bottom mold. Then the top mold moves down and works with the bottom mold to complete the stamping of the workpieces. Since multiple hardware workpieces are involved, the operator needs to manually and accurately place them in the designated positions. This repetitive action greatly increases the labor intensity of the operator. At the same time, the operator's hands are easily injured by the stamping forming equipment during frequent operation, which makes the stamping forming equipment a safety hazard.

[0022] In view of this, the present invention provides a metal stamping forming device, which places metal tubes sequentially above the bottom mold through a feeding mechanism. During the stamping process, the metal tubes do not require frequent operation by the operator, reducing the labor intensity of the workers. At the same time, the workers' hands will not come into contact with the stamping forming device, preventing accidental injury to the workers' hands and solving the safety hazard problem of the stamping forming device.

[0023] Example 1: By Figure 1 , 2 As can be seen from points 3, 4, and 5, a metal stamping forming device includes a device frame 1. A workbench 4 is fixedly connected to the bottom of the device frame 1, and a support leg 8 is fixedly connected to the bottom of the workbench 4. A control panel 11 is fixedly connected to the top of the workbench 4. A storage box 6 is installed inside the device frame 1. The storage box 6 is equipped with a feeding mechanism 7. The feeding mechanism 7 includes: two limiting plates 71, both fixedly connected to the upper inner wall of the storage box 6; and a second electric push rod 72 rotatably connected to the two limiting plates 71. One end of the device is connected to the control panel 11 via a wire; the rotating block 73 is rotatably connected to the output end of the second electric push rod 72 and is rotatably connected to the inner wall of the storage box 6 away from the limiting plate 71 via a bearing; two baffles 74 are provided, both of which are slidably engaged in the groove of the rotating block 73 and are inserted into the inner wall of the storage box 6; wherein, when the second electric push rod 72 is working, it drives the two baffles 74 to move up and down alternately through the rotating block 73, restricting the internal pipes of the storage box 6 to be discharged outward in sequence to complete the feeding;

[0024] In the specific implementation process, it is worth noting that the support leg 8 makes the workbench 4 more stable when in use. The metal pipe raw materials are placed inside the storage box 6. The control panel 11 and the second electric push rod 72 are not limited in model, as long as they meet the usage requirements. When the second electric push rod 72 is working, it drives the rotating block 73 to rotate. The rotating block 73 drives the two baffles 74 to move up and down alternately, so as to discharge the pipes inside the storage box 6 outward in sequence, thereby completing the expected operation.

[0025] Furthermore, a collection box 9 is placed inside the support leg 8 on the side away from the control panel 11, and a hopper 10 is fixedly connected to the inner wall of the workbench 4 on the side away from the control panel 11, with the hopper 10 extending through the bottom of the workbench 4.

[0026] In the specific implementation process, it is worth noting that the formed metal pipes fall from the hopper 10 into the collection box 9 for centralized collection.

[0027] Furthermore, a bottom mold 5 is fixedly connected to the top of the workbench 4 by bolts, and a top mold 3 is provided on the top of the bottom mold 5;

[0028] In the specific implementation process, it is worth noting that the bolt fixing method makes it easy to disassemble and replace the bottom mold 5, which is used in conjunction with the top mold 3;

[0029] Specifically, when using this metal stamping and forming device, the bottom mold 5 is fixed above the worktable 4 with bolts. The formed metal pipe falls into the collection box 9 through the hopper 10. The operator puts the metal pipe to be processed into the storage box 6 and controls the second electric push rod 72 through the control panel 11. The second electric push rod 72 drives the rotating block 73 to drive the two baffles 74 to move up and down alternately. When the baffle 74 on the side closer to the limit plate 71 moves upward, the metal pipe rolls downward due to gravity and is blocked by the baffle 74 on the side farther away from the limit plate 71. When the baffle 74 on the side farther away from the limit plate 71 moves upward, the metal pipe rolls from the storage box 6 to the top of the bottom mold 5. The baffle 74 on the side closer to the limit plate 71 blocks other metal pipes inside the storage box 6. This method can automatically feed metal pipes and reduce the workload of the operator.

[0030] Example 2: From Figure 1 , 2As shown in section 4, the internal structure of the device frame 1 is equipped with a moving mechanism 2, which includes: a servo motor 21, fixedly connected to the outer wall of the device frame 1 near the control panel 11 and electrically connected to the control panel 11 via a wire; a lead screw 22, rotatably connected to the inner wall of the device frame 1 via a bearing and fixedly connected to the output end of the servo motor 21; a sliding plate 23, threadedly connected to the outer wall of the lead screw 22 near the servo motor 21 and slidably engaged with the inner wall of the device frame 1; two first electric push rods 24, both fixedly connected to the bottom of the sliding plate 23 and electrically connected to the control panel 11 via a wire; a base plate 25, fixedly connected to the output ends of the two first electric push rods 24 and fixedly connected to the top of the top mold 3 via bolts; and an electromagnet 26, fixedly connected to the inner wall of the base plate 25 and electrically connected to the control panel 11 via a wire. When the servo motor 21 is working, it drives the sliding plate 23 to move via the lead screw 22, and the sliding plate 23 drives the top mold 3 below the base plate 25 to a designated position via the two first electric push rods 24.

[0031] In the specific implementation process, it is worth noting that the models of servo motor 21, first electric push rod 24 and electromagnet 26 are not limited, as long as they meet the usage requirements. The servo motor 21 drives the lead screw 22 to rotate, and the lead screw 22 drives the two first electric push rods 24 to move through the slide plate 23. The two first electric push rods 24 drive the top mold 3 under the base plate 25 to move to the designated position. The electromagnet 26 can attract the formed metal tube to the bottom of the top mold 3.

[0032] Furthermore, two curved plates 231 are fixedly connected to the bottom of the skateboard 23;

[0033] In the specific implementation process, it is worth noting that when the skateboard 23 moves, it drives the two curved boards 231 to move;

[0034] Specifically, based on the above embodiment 1, the operator controls the two first electric push rods 24 through the control panel 11. The two first electric push rods 24 drive the top mold 3 to move downward through the base plate 25. The top mold 3 cooperates with the bottom mold 5 to stamp and form the metal tube. The operator controls the electromagnet 26 to work. The electromagnet 26 attracts the formed metal tube below the top mold 3. The two first electric push rods 24 drive the formed metal tube to half the height of the stroke of the first electric push rods 24. The operator controls the servo motor 21 to work. The servo motor 21 drives the slide plate 23 to move through the lead screw 22. The slide plate 23 drives the top mold 3 under the base plate 25 to move through the first electric push rods 24. After the top mold 3 drives the formed metal tube to move above the discharge hopper 10, the electromagnet 26 stops working. At the same time, the two first electric push rods 24 drive the lower top mold 3 to continue to move upward. The metal tube below the top mold 3 is restricted by the two bending plates 231 and falls into the collection box 9 through the discharge hopper 10.
