Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically a stamping fixture with high protective performance. Background Technology

[0002] In modern manufacturing, stamping is a widely used metal processing method. It uses dies and pressure equipment to plastically deform workpieces such as sheet metal to obtain the desired shape and size. Stamping fixtures, as key equipment in the stamping process, directly affect the quality and production efficiency of stamped products.

[0003] In terms of protective design, traditional stamping fixtures typically cannot effectively prevent the flying debris generated during the stamping process. During stamping, metal materials are punched at high speed under pressure, and the resulting debris flies outwards at extremely high speeds. If this debris gets into the operator's eyes, it can cause serious injury or even blindness.

[0004] Furthermore, the feeding and removal of workpieces during the stamping process are also key factors affecting production efficiency. Some stamping fixtures lack reasonable workpiece feeding and positioning mechanisms, resulting in long operation times, high labor intensity, and hindering the realization of automated production.

[0005] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] A high-protection stamping fixture includes a base on which a protective frame is mounted;

[0008] The protective frame is equipped with a stamping mechanism, which includes an upper die and a lower die that can move relative to each other. The upper die and the lower die cooperate to form a stamping cavity for stamping the workpiece.

[0009] The top of the protective frame is provided with a first driving device. The movable end of the first driving device passes through the protective frame in the vertical direction and is connected to the upper mold, which is used to drive the upper mold to perform stamping motion.

[0010] The protective frame has an opening on the front side. A linear guide rail is installed on the base at the position corresponding to the opening. A movable plate is connected to the linear guide rail via a slider. The movable plate is connected to the lower mold. A handle is connected to the front side of the movable plate. The movable plate can drive the lower mold to enter the protective frame along the linear guide rail and dock with the upper mold. The movable plate can also drive the lower mold to move along the linear guide rail to the outside of the protective frame.

[0011] A second driving device is installed on both the left and right sides of the protective frame. The movable end of the second driving device passes through the protective frame in the horizontal direction and is engaged with the movable plate. The movable plate has a bayonet on both the left and right sides corresponding to the movable end of the second driving device.

[0012] As a further embodiment of this utility model: a protective frame is installed on the base so that the base is located on the front side of the protective frame to form an operating area, and located on the inner side of the protective frame to form a stamping area, and the linear guide rail extends from the operating area to the stamping area.

[0013] As a further embodiment of this utility model: a limiting plate is provided on the base and located in the stamping area, and the movable plate and the limiting plate are limited and abutted together.

[0014] As a further embodiment of this utility model: the movable plate includes a horizontal plate and a connected vertical plate, and the horizontal plate and the vertical plate are connected to form an L-shaped structure;

[0015] The horizontal plate engages with the movable end of the second driving device, and the vertical plate engages with the limiting plate.

[0016] As a further embodiment of this utility model: the bayonet is provided along the end face of the horizontal plate, and the horizontal plate is detachably connected to a flexible component at the bayonet.

[0017] As a further embodiment of this utility model: the shape of the flexible member is adapted to the shape of the movable plate at its slot, so that the inner side of the flexible member fits into the slot, and the outer side of the flexible member forms a slot that cooperates with the second driving device.

[0018] The flexible component is also provided with a connection structure that connects to the movable plate.

[0019] As a further embodiment of this utility model: a control panel is provided on the front side of the base, and a first control button and a second control button electrically connected to the control panel;

[0020] The first control button is electrically connected to the first drive device, and the second control button is electrically connected to the second drive device.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1) The protective frame effectively prevents debris from flying and injuring operators. During the stamping process, the debris is blocked inside the protective frame, which greatly reduces the risk of debris flying and provides operators with a relatively safe working environment.

[0032] 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.

[0033] Please see Figure 1-4 In this embodiment of the present invention, a high-protection stamping fixture includes a base 1, on which a protective frame 2 is installed;

[0034] The protective frame 2 is equipped with a stamping mechanism, which includes an upper die 3 and a lower die 4 that can move relative to each other. The upper die 3 and the lower die 4 cooperate to form a stamping cavity for stamping the workpiece.

[0035] The top of the protective frame 2 is provided with a first driving device 5. The movable end of the first driving device 5 passes through the protective frame 2 in the vertical direction and is connected to the upper mold 3, which is used to drive the upper mold 3 to perform stamping motion.

[0036] The protective frame 2 has a movable opening 6 on its front side. A linear guide rail 7 is installed on the base 1 at the position corresponding to the movable opening 6. A movable plate 8 is connected to the linear guide rail 7 via a slider. The movable plate 8 is connected to the lower mold 4. A handle 9 is connected to the front side of the movable plate 8. The movable plate 8 can drive the lower mold 4 to enter the protective frame 2 along the linear guide rail 7 and dock with the upper mold 3. The movable plate 8 can also drive the lower mold 4 to move along the linear guide rail 7 to the outside of the protective frame 2.

[0037] The protective frame 2 is equipped with a second driving device 10 on both the left and right sides. The movable end of the second driving device 10 passes through the protective frame 2 in the horizontal direction and is connected to the movable plate 8. The movable plate 8 is provided with a bayonet 11 on both the left and right sides corresponding to the movable end of the second driving device 10.

[0038] In this utility model, the protective frame 2 is made of metal material. Its structural design can effectively block the flying debris generated during the stamping process. It surrounds the stamping mechanism to form a closed space, which restricts the debris generated during the stamping process to the inside. The inner wall of the protective frame 2 is smooth and has a certain strength, which can withstand the impact force generated during stamping and prevent the debris from breaking through the protective frame 2. At the same time, the top and sides of the protective frame 2 are provided with sealing structures to prevent the debris from escaping from the gaps.

[0039] The protective frame 2 is tightly connected to the base 1, providing stable support for the stamping mechanism. The base 1 is fixed to the protective frame 2 with bolts to ensure that the protective frame 2 will not shift during the stamping process. The internal structure of the protective frame 2 is reasonably designed to accommodate all the components of the stamping mechanism and provide them with sufficient space.

[0040] The upper die 3 and the lower die 4 are the core components of the stamping mechanism. Their shape and size are designed according to the requirements of the workpiece. The stamping mechanism uses pressure to make the upper die 3 and the lower die 4 move relative to each other to stamp the workpiece. When the first drive device 5 drives the upper die 3 to move downward, pressure is generated between the upper die 3 and the lower die 4, causing the workpiece to undergo plastic deformation under the action of the die.

[0041] The first drive device 5 is installed on the top of the protective frame 2, and its movable end is connected to the upper mold 3 through a connecting component. The drive device adopts a hydraulic or electric drive method and can provide stable power output. The second drive device 10 is installed on the left and right sides of the protective frame 2. Its movable end is connected to the movable plate 8 through a connecting component (such as a connecting pin, which can be cylindrical or other shapes, with one end fixed to the movable end of the second drive device 10 and the other end inserted into the corresponding slot 11 on the movable plate 8). The second drive device 10 can adopt an electric drive method and can achieve precise positioning of the movable plate 8.

[0042] The movable plate 8 is connected to the linear guide rail 7 via a slider. The slider slides on the linear guide rail 7, and the bottom of the movable plate 8 is fixedly connected to the slider to ensure that the movable plate 8 can move smoothly on the linear guide rail 7. The movement of the movable plate 8 is manual. The operator pushes the movable plate 8 along the linear guide rail 7 by holding the handle 9. The movement speed and direction of the movable plate 8 can be adjusted according to the operator's needs. When the movable plate 8 enters the protective frame 2, the movable end of the second drive device 10 is inserted into the slot 11 of the movable plate 8 to achieve the positioning of the movable plate 8. Then, the first drive device 5 is driven to drive the upper mold 3 to perform a stamping motion.

[0043] In summary, the protective frame 2 effectively prevents debris from splashing and injuring operators. During the stamping process, debris is blocked inside the protective frame 2, greatly reducing the risk of debris splashing and providing operators with a relatively safe working environment. The design of the movable plate 8 makes the loading and unloading of workpieces more convenient and faster. Operators can push the movable plate 8 with the handle 9 to send the workpiece into the protective frame 2 and then perform the stamping operation. At the same time, the design of the second drive device 10 enables the movable plate 8 to be precisely positioned. After the movable plate 8 enters the protective frame 2, the movable end of the second drive device 10 inserts into the bayonet 11 of the movable plate 8 to achieve the positioning of the movable plate 8. After the stamping is completed, the lower die 4 can be pulled out, which facilitates the operator to load and unload materials.

[0044] In this embodiment of the utility model, a protective frame 2 is installed on the base 1 so that the base 1 forms an operating area 12 on the front side of the protective frame 2 and a stamping area 13 on the inner side of the protective frame 2. The linear guide rail 7 extends from the operating area 12 to the stamping area 13.

[0045] The protective frame 2 divides the area where the base 1 is located. The base 1 is located in front of the protective frame 2 to form the operating area 12, which is used to place the workpiece to be processed, tools, and operators for operation. The inner side of the protective frame 2 forms the stamping area 13, which is the area where the stamping mechanism works. Through this division, the functions are separated, so that the operators can work safely and orderly in the operating area 12, while avoiding the danger of the stamping area 13 affecting the operating area 12.

[0046] The linear guide rail 7 extends from the operating area 12 to the stamping area 13. This design allows the movable plate 8 to move smoothly between the operating area 12 and the stamping area 13. The movable plate 8 is connected to the linear guide rail 7 via a slider and moves on the linear guide rail 7 to realize the back-and-forth movement of the lower die 4 between the operating area 12 and the stamping area 13. The design of the linear guide rail 7 ensures the movement trajectory and stability of the movable plate 8, so that the lower die 4 can accurately enter the stamping area 13 and dock with the upper die 3. It also facilitates the return of the lower die 4 to the operating area 12 after stamping.

[0047] In this embodiment of the utility model, a limiting plate 14 is provided on the base 1 and located in the stamping area 13, and the movable plate 8 is limited and abutted with the limiting plate 14.

[0048] When the movable plate 8 moves along the linear guide 7 into the stamping zone 13, it will contact the limiting plate 14. The position of the limiting plate 14 is determined according to the working requirements of the stamping zone 13 and the movement trajectory of the movable plate 8, ensuring that the movable plate 8 can accurately reach the designated position when entering the stamping zone 13. The limiting plate 14 and the movable plate 8 adopt a limiting abutment cooperation method. When the movable plate 8 moves along the linear guide 7 to the stamping zone 13, the edge of the movable plate 8 abuts against the limiting plate 14. This abutment method can limit the position of the movable plate 8 and prevent the movable plate 8 from moving excessively or moving to the wrong position in the stamping zone 13. That is, the design of the limiting plate 14 makes the movement of the movable plate 8 in the stamping zone 13 more stable and ensures the smooth progress of the stamping process.

[0049] In this embodiment of the utility model, the movable plate 8 includes a horizontal plate 15 and a connected vertical plate 16, and the horizontal plate 15 and the vertical plate 16 are connected to form an L-shaped structure;

[0050] The horizontal plate cooperates with the movable end of the second driving device 10, and the vertical plate 16 cooperates with the limiting plate 14.

[0051] The horizontal plate 15 is mainly used to dock with the movable end of the second drive device 10. By connecting the component to the movable end of the second drive device 10, the movable plate 8 can move in the horizontal direction. The vertical plate 16 is used to cooperate with the limiting plate 14 to position and limit the position of the movable plate 8 in the stamping area 13.

[0052] The L-shaped structure causes the movable plate 8 to be subjected to different forces in different directions. The horizontal plate 15 is subjected to the force of the second driving device 10 in the horizontal direction, while the vertical plate 16 is subjected to the force of the limiting plate 14 in the vertical direction. This structural design can effectively disperse the force borne by the movable plate 8 and improve the stability and reliability of the movable plate 8.

[0053] In this embodiment of the utility model, the bayonet 11 is provided along the end face of the horizontal plate 15, and the horizontal plate 15 is detachably connected to the flexible member 17 at the bayonet 11.

[0054] The shape of the flexible member 17 is adapted to the shape of the movable plate 8 at its slot 11, so that the inner side of the flexible member 17 fits into the slot 11, and the outer side of the flexible member 17 forms a slot 18 that cooperates with the second driving device 10.

[0055] The flexible component 17 is also provided with a connection structure 19 that is connected to the movable plate 8.

[0056] A slot 11 is provided along the end face of the horizontal plate 15. The shape and size of the slot 11 are designed according to the connection requirements between the movable plate 8 and the second drive device 10. The slot 11 is a groove with a certain depth and shape, used to accommodate the flexible part 17.

[0057] The shape of the flexible part 17 is adapted to the shape of the movable plate 8 at the bayonet 11. It is made of a soft and elastic material and can fit tightly to the bayonet 11 of the movable plate 8. The inner side of the flexible part 17 is fitted into the bayonet 11 to ensure that its connection with the movable plate 8 is stable. At the same time, the outer side of the flexible part 17 forms a groove 18 that cooperates with the second drive device 10. The shape and size of the groove 18 match the movable end of the second drive device 10, which can achieve precise docking between the two.

[0058] The flexible component 17 is provided with a connection structure 19 that connects to the movable plate 8. This connection structure 19 can be in the form of bolts, nuts, buckles, etc., and the flexible component 17 and the movable plate 8 are firmly connected together through these connection structures 19.

[0059] The flexible component 17 is connected to the movable plate 8 through the connecting structure 19. During the installation process, the inner side of the flexible component 17 is embedded into the bayonet 11, and then it is fixed to the movable plate 8 through the connecting structure 19. This connection method makes the flexible component 17 and the movable plate 8 form a tight connection, which can withstand a certain amount of external force.

[0060] The outer side of the flexible member 17 forms a slot 18 that cooperates with the second drive device 10. When the movable end of the second drive device 10 is inserted into the slot 18, the flexible member 17 can transmit the force of the second drive device 10 to the movable plate 8. The softness of the flexible member 17 allows it to buffer the impact force of the second drive device 10 to a certain extent, preventing the movable plate 8 from being damaged by excessive force. At the same time, the elasticity of the flexible member 17 can also ensure the stability of the connection between the second drive device 10 and the movable plate 8, improving the reliability of the connection.

[0061] In this embodiment of the utility model, a control panel 20 is provided on the front side of the base 1, as well as a first control button 21 and a second control button 22 electrically connected to the control panel 20;

[0062] The first control button 21 is electrically connected to the first drive device 5, and the second control button 22 is electrically connected to the second drive device 10.

[0063] The control panel 20 is equipped with a first control button 21 and a second control button 22, which correspond to the first drive device 5 and the second drive device 10, respectively. With this layout, the operator can easily operate the different functions of the stamping fixture. When the operator presses the first control button 21, the first drive device 5 receives a signal and starts the stamping movement of the upper die 3. Similarly, when the second control button 22 is pressed, the second drive device 10 receives a signal and realizes the snap-fit ​​positioning of the movable plate 8.

[0064] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
