Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a metal part stamping die with a protective structure. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping dies consist of a fixed part and a moving part. The fixed part is fastened to the worktable of the press with pressure plates, bolts, etc., while the moving part is generally fastened to the slide of the press. There are various types of stamping dies, such as blanking dies, drawing dies, bending dies, flanging dies, and hemming dies. They are widely used in various fields, including automobiles, electronics, and daily hardware.

[0003] In current stamping dies, the lower die body is fixed to the press table during stamping, while the upper die body is fixed to the lower part of the driving stamping mechanism. Before and after the upper die body moves down to stamp and closes with the lower die body, the workpiece is manually placed into the lower die body cavity by the operator. When the operator places or removes the workpiece, accidentally triggering the driving stamping mechanism to move down may cause safety hazards to the operator, thus posing a certain degree of danger. To address this problem, we provide a metal part stamping die with a protective structure. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution for a metal stamping die with a protective structure that can solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal stamping die with a protective structure, comprising a die base, an upper end of which is provided with a track groove, and an outer side of which is provided with a side groove communicating with the track groove. A lower die is provided in the inner cavity of the track groove. The lower die consists of a base and a bottom die. Mounting grooves are provided on both sides of the lower die. A fixing component is installed in the inner cavity of the mounting grooves on both sides of the lower die. A first rack is connected to the outer side of the fixing component. An upper die is provided above the lower die. A top seat is installed at the upper end of the upper die. A switching mechanism is installed on the outer side of the top seat.

[0006] The switching mechanism includes a fixed seat connected to the top seat, a support plate installed on the outer side of the fixed seat, a second rack installed on the outer side of the support plate, a second gear meshing on the outer side of the second rack, a transmission shaft installed in the inner cavity of the second gear, and a first gear meshing with the first rack installed on the outer side of the transmission shaft.

[0007] As a further embodiment of this utility model: a support frame is installed at the upper end of the mold base, a hydraulic cylinder is installed at the upper end of the support frame, the output end of the hydraulic cylinder is connected to a mounting base, and the lower end of the mounting base is connected to a top seat.

[0008] As a further embodiment of this utility model: a support seat is movably sleeved on the outer side of the transmission shaft, the support seat is installed at the bottom end of the inner cavity of the side groove, the lower ends of the support plate and the second rack penetrate through the mold seat and extend into the inner cavity of the side groove, and a through groove corresponding to the position of the support plate is provided at the bottom end of the inner cavity of the side groove.

[0009] As a further embodiment of this utility model: square grooves are provided on both the upper and lower parts of the outer side of the support plate, and limiting posts are connected to the inner cavities of the square grooves. A base plate is movably sleeved on the outer side of each limiting post, and a spring is connected to one end of each base plate. A toothed block is movably sleeved on the outer side of each limiting post, and the end of each spring away from the base plate is connected to the toothed block.

[0010] As a further embodiment of this utility model: the fixing component includes two sets of fixing strips disposed in the inner cavities of two mounting slots. Each inner cavity of the mounting slot is provided with multiple threaded holes. Each fixing strip is screwed to the threaded holes by multiple bolts. A sliding strip is symmetrically connected to the outer side of one set of fixing strips. A sliding groove is provided on one side of the inner cavity of the track groove for sliding contact with the sliding strip. A fixing plate is connected to the outer side of the other set of fixing strips. The fixing plate is screwed to the first rack. Two sets of baffles are installed in the inner cavity of the track groove.

[0011] As a further embodiment of this utility model: the upper end of the mold base is connected to four sets of positioning pins, and the upper end of the top base is provided with four sets of positioning holes that are inserted into it.

[0012] As a further embodiment of this utility model: the upper end of the mold base is provided with an outer cover, which is located outside the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Simultaneously, the hydraulic cylinder output drives the mounting base, top seat, and upper die to move downwards. The top seat then drives the switching mechanism downwards, which in turn moves the fixed components and lower die. This allows the base of the lower die to move to the left of the upper die, and the bottom die to move directly below the upper die. This facilitates the closing of the upper and lower dies to complete the stamping of the workpiece. Afterwards, the upper die and other components move upwards and reset, causing the switching mechanism to reset the first rack, fixed components, and lower die. The base of the lower die then moves directly below the upper die, and the bottom die moves to the right of the upper die. This allows workers to easily remove and reposition the workpiece, and automatically moves the bottom die away from the upper die. This prevents workers from accidentally triggering the hydraulic cylinder switch, which could cause the upper die to automatically move downwards during stamping, creating a safety hazard. By moving the bottom die away from the upper die for workpiece removal and placement, safety is significantly improved, enhancing the protective effect of this stamping die.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-7 As shown, a metal stamping die with a protective structure includes a die base 1. The upper end of the die base 1 is provided with a track groove 2. The outer side of the die base 1 is provided with a side groove 14 that communicates with the track groove 2. The inner cavity of the track groove 2 is provided with a lower die 3. The lower die 3 is composed of a base and a bottom die. An upper die 11 is provided above the lower die 3. A top seat 5 is installed at the upper end of the upper die 11. A support frame 8 is installed at the upper end of the die base 1. A hydraulic cylinder 9 is installed at the upper end of the support frame 8. The output end of the hydraulic cylinder 9 is connected to a mounting seat 10. The lower end of the mounting seat 10 is connected to the top seat 5. Four sets of positioning pins 7 are connected to the upper end of the die base 1. Four sets of positioning holes that are inserted into the top seat 5 are provided at the upper end of the top seat 5.

[0026] The positioning holes at the top of the top seat 5 are connected to the four sets of positioning pins 7. When the workpiece is stamped, the output end of the hydraulic cylinder 9 drives the mounting seat 10, the top seat 5 and the upper mold 11 to move down. The top seat 5 moves stably outside the positioning pins 7 through the positioning holes, which makes it easy to ensure that the upper mold 11 can accurately and stably close with the lower mold 3, so as to effectively stamp the workpiece placed in the inner cavity of the lower mold 3.

[0027] Please see Figure 2-5As shown, both sides of the lower mold 3 are provided with mounting grooves 17. The inner cavities of the mounting grooves 17 on both sides of the lower mold 3 are jointly equipped with fixing components 4. The fixing components 4 include two sets of fixing strips 41 set in the inner cavities of the two mounting grooves 17. The inner cavities of the mounting grooves 17 are provided with multiple threaded holes 18. The fixing strips 41 are screwed to the threaded holes 18 by multiple bolts 42. The outer side of one set of fixing strips 41 is symmetrically connected with sliding strips 43. The inner cavity of the track groove 2 is provided with a sliding groove 16 that slides with it. The outer side of the other set of fixing strips 41 is connected with a fixing plate 44. The fixing plate 44 is screwed to the first rack 45. The inner cavity of the track groove 2 is equipped with two sets of baffles 13.

[0028] The fixing strip 41 of the fixing component 4 is screwed into the threaded hole 18 inside the mounting groove 17 on the outside of the two sets of lower molds 3 by bolts 42. This allows the fixing strip 41 to effectively fix the two sets of lower molds 3. When the switching mechanism 6 moves the first rack 45, the first rack 45 moves the fixing strip 41 and the lower mold 3 through the fixing plate 44, so that the base of the lower mold 3 moves to the left and the bottom mold moves directly below the upper mold 11, which facilitates the effective stamping of the workpiece. The slide 43 on the outside of one of the fixing strips 41 slides in the inner cavity of the slide groove 16, which effectively improves the stability of the movement of the two sets of lower molds 3. The two sets of baffles 13 designed by the component effectively shield and protect the lower molds 3.

[0029] Please see Figure 1-2 As shown in Figures 4 and 6-7, a switching mechanism 6 is installed on the outer side of the top seat 5. The switching mechanism 6 includes a fixed seat 61 connected to the top seat 5. A support plate 62 is installed on the outer side of the fixed seat 61. A second rack 63 is installed on the outer side of the support plate 62. A second gear 67 meshes with the outer side of the second rack 63. A drive shaft 65 is installed in the inner cavity of the second gear 67. A first gear 66 meshes with the first rack 45 on the outer side of the drive shaft 65. A support seat 64 is movably sleeved on the outer side of the drive shaft 65. The support seat 64 is installed at the bottom end of the inner cavity of the side groove 14. The lower ends of the support plate 62 and the second rack 63 penetrate the mold seat 1 and extend into the inner cavity of the side groove 14. A through groove 15 corresponding to the position of the support plate 62 is provided at the bottom end of the inner cavity of the side groove 14.

[0030] Square grooves 68 are provided on the upper and lower parts of the outer side of the support plate 62. The inner cavity of the square grooves 68 is connected to the limiting post 610. The outer side of the limiting post 610 is movably sleeved with a base plate 69. One end of the base plate 69 is connected to a spring 611. The outer side of the limiting post 610 is movably sleeved with a toothed block 612. The end of the spring 611 away from the base plate 69 is connected to the toothed block 612.

[0031] Simultaneously, the output end of the hydraulic cylinder 9 drives the mounting base 10, the top seat 5, and the upper mold 11 to move downwards. The top seat 5 also drives the fixed base 61, the support plate 62, and the second rack 63 to move downwards. At this time, a workpiece is placed in the bottom mold cavity of the lower mold 3. As the support plate 62 and the second rack 63 move downwards, the second rack 63 drives the meshing second gear 67 to rotate. The transmission shaft 65 inside the second gear 67 rotates synchronously, simultaneously driving the first gear 66 to rotate. The first gear 66 then drives the first rack 45 to move. The first rack 45 drives the fixed assembly and the lower mold 3 to move. At this time, the base of the lower mold 3, which is located directly below the upper mold 11, moves to the left, and the bottom mold of the lower mold 3 moves directly below the upper mold 11. Meanwhile, the top seat 5 and the upper mold 11 continue to move downward, and the second rack 63 moves downward until it disengages from the second gear 67. At the same time, the tooth block 612 meshes with the second gear 67, thereby limiting and fixing the second gear 67, that is, limiting the transmission shaft 65, the first gear 66, and the first rack 45. The top seat 5 and the upper mold 11 are fixed, thus limiting and fixing the position of the fixed component 4 and the lower mold 3. As the top seat 5 and the upper mold 11 continue to move downward, the top seat 5 drives the fixed seat 61 and the support plate 62 to continue to move downward. The support plate 62 begins to compress the spring 611, always keeping the tooth block 612 meshing with the second gear 67 to limit and fix it. This ensures that the upper mold 11 can stably press down and close with the bottom mold of the lower mold 3, facilitating precise stamping of the workpiece. After the workpiece is stamped, the upper mold and other components move upward and reset, causing the switching mechanism 6 to drive the first rack 45, the fixed component 4, and the lower mold 3 to reset. As a result, the base of the lower mold 3 moves to the bottom of the upper mold 11 and resets, while the bottom mold moves to the right side of the upper mold 11, making it convenient for the operator to pick up and reposition the workpiece. This allows the bottom mold to automatically move away from the upper mold 11, avoiding the operator accidentally triggering the hydraulic cylinder switch, which could cause the upper mold 11 to automatically move downward and stamp, creating a safety hazard. Thus, by moving the bottom mold away from the upper mold 11 for picking up and placing the workpiece, the safety of the operation is effectively improved, and the operational efficiency is increased.

[0032] The upper end of the mold base 1 is provided with an outer cover 12, which is located outside the support plate 62. This facilitates effective protection and shielding of the support plate 62 and other components, thus providing effective protection.

[0033] Working principle: Simultaneously, the output end of the hydraulic cylinder 9 drives the mounting base 10, top seat 5, and upper mold 11 to move downwards. The top seat 5 then drives the fixed base 61, support plate 62, and second rack 63 to move downwards. Subsequently, the second rack 63 drives the meshing second gear 67 to rotate. The transmission shaft 65 within the second gear 67 rotates synchronously, simultaneously driving the first gear 66 to rotate. The first gear 66 then drives the first rack 45 to move, which in turn moves the fixed assembly and lower mold 3. At this time, the base of the lower mold 3, located directly below the upper mold 11, moves. The lower mold 3 moves to the left, and the bottom mold of the lower mold 3 moves directly below the upper mold 11. At the same time, the top seat 5 and the upper mold 11 continue to move downwards, while the second rack 63 moves downwards until it disengages from the second gear 67. Simultaneously, the tooth block 612 meshes with the second gear 67, thereby limiting and fixing the second gear 67, that is, limiting and fixing the transmission shaft 65, the first gear 66, and the first rack 45, thereby limiting and fixing the position of the fixing component 4 and the lower mold 3. As the top seat 5 and the upper mold 11 continue to move downwards, the top seat 5 drives the fixing seat 61 and the support plate 62 to continue moving downwards. As the upper die moves downward, the support plate 62 compresses the spring 611, maintaining the meshing and limiting fixation of the toothed block 612 and the second gear 67. This ensures that the upper die 11 can stably press down and close with the bottom die of the lower die 3, facilitating precise stamping of the workpiece. After stamping, the upper die and other components move upward and reset, causing the switching mechanism 6 to drive the first rack 45, the fixing component 4, and the lower die 3 to reset. Consequently, the base of the lower die 3 moves to the right side of the upper die 11, facilitating the removal and repositioning of parts by the workers. The workpiece is moved away from the upper mold 11 by the bottom mold, which facilitates automatic removal of the workpiece from the upper mold 11. This avoids the safety hazards caused by workers accidentally triggering the hydraulic cylinder switch, which could lead to the upper mold 11 automatically moving down for stamping. The operation of picking up and placing the workpiece by moving the bottom mold away from the upper mold 11 effectively improves safety and enhances the operational efficiency. At the same time, the toothed block 612 in the inner cavity of the other square groove 68 of the support plate 62 meshes with the lower part of the second gear 67 to limit and fix the current position of the lower mold 3, making it easier for workers to pick up or place the workpiece from the lower mold 3 more stably, thus effectively improving the operational efficiency.
