Description

Technical Field

[0001] The utility model relates to a blowing device, in particular to an iron core progressive die blowing device which can prevent foreign matter from entering. Background Art

[0002] A progressive die is a die used for metal stamping and forming, usually used to complete multiple processes in one stamping process. It uses a series of die cavities and slider designs to enable metal materials to gradually complete multiple processes from raw materials to final products in each stamping cycle. The core progressive die is a die specially used to manufacture core components in equipment such as motors and transformers. It processes metal materials into the required shape and size through a multi-step stamping and forming process.

[0003] During the continuous stamping production of the iron core progressive die, an uninterrupted supply of metal materials is required. If there are foreign objects on the surface of the metal material during stamping, the size of the iron core produced by the stamping will be different. Therefore, whether there are foreign objects on the surface of the metal material determines the stamping quality of the iron core produced by the stamping. In the current use process of the iron core progressive die, there is no mechanism for removing foreign objects attached to the surface of the metal material, which will cause foreign objects to adhere to the metal material and be stamped together with the progressive die, affecting the stamping production quality of the iron core.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] See also Figures 1 to 11In an embodiment of the present invention, a blowing device for a progressive die for an iron core that prevents foreign matter from entering is provided at both ends of a lower die base 1 along the length direction of the lower die base 1. An upper die base 2 for cooperating with the lower die base 1 for stamping is vertically movably provided above the lower die base 1. The blowing device for a progressive die for an iron core that prevents foreign matter from entering comprises a high-pressure air distribution pipe 16. A plurality of nozzles 17 are linearly and evenly spaced in the length direction of the high-pressure air distribution pipe 16. At least one end of the high-pressure air distribution pipe 16 is connected to and fixedly provided with an air supply pipe 18, and the air supply pipe 18 is connected to an air pump.

[0041] A driving structure that cooperates with the high-pressure gas distribution pipe 16 is provided between the lower mold base 1 and the upper mold base 2. When the lower mold base 1 and the upper mold base 2 are closed or opened, the driving structure enables the high-pressure gas distribution pipe 16 to move from one side of the lower mold base 1 to the other side along the width direction of the lower mold base 1;

[0042] In addition, when the high-pressure air distribution pipe 16 moves, the nozzle 17 sprays air to blow away foreign matter remaining on the lower die base 1 due to stamping.

[0043] In this embodiment, when the lower mold base 1 and the upper mold base 2 are closed or opened, the driving structure can be driven to operate. The high-pressure air distribution pipe 16 on the driving structure will slide in the width direction of the lower mold base 1, and cooperate with the air supply pipe 18 to connect with the external air pump. The external air pump supplies air to the high-pressure air distribution pipe 16 through the air supply pipe 18. A solenoid valve is provided at the nozzle 17 to control the air outlet and air closing state of the nozzle 17, and the nozzle 17 is set at a 60-degree inclination angle with the high-pressure air distribution pipe 16. When the lower mold base 1 and the upper mold base 2 are opened, The high-pressure air distribution pipe 16 is displaced on the driving structure in the inclined direction toward the nozzle 17. At this time, the solenoid valve at the nozzle 17 is opened, and the air flow supplied into the high-pressure air distribution pipe 16 will pour out to blow away the foreign matter on the lower mold base 1. When the mold is closed, the high-pressure air distribution pipe 16 is reset. At this time, the solenoid valve on the nozzle 17 is in a closed state, and the air pump connected to the air supply pipe 18 continues to pump air into the high-pressure air distribution pipe 16, waiting for the next time the nozzle 17 is deflated for use, which can increase the air flow intensity and improve the effect of blowing and cleaning foreign matter.

[0044] As a further solution of the present invention, the driving structure includes a fixing assembly provided at both ends of the lower die base 1 in the longitudinal direction, a screw 6 provided on the fixing assembly, a linkage assembly provided at both ends of the screw 6, and a transmission assembly connected to the linkage assembly;

[0045] The fixing assembly includes a mounting frame 3 mounted on the lower die base 1 by bolts, a U-shaped frame 4 fixedly connected at both ends of the mounting frame 3, and a guide column 5 integrally formed at the bottom of the U-shaped frame 4 on the side away from the mounting frame 3, and the screw 6 is rotatably connected between the two U-shaped frames 4 at both ends of the mounting frame 3;

[0046] The transmission assembly is detachably mounted on the upper die base 2 , and the transmission assembly drives the linkage assembly to operate when the upper die base 2 is in mold closing or mold opening motion.

[0047] In this embodiment, the installation and use of various components of the device can be met by the setting of the fixing components. The mounting frame 3 is installed at both ends of the length direction of the lower mold base 1 by bolts. U-shaped frames 4 are fixedly provided at both ends of the mounting frame 3. The connecting screw 6 is rotated between the two U-shaped frames 4, and the linkage part is moved through the transmission part, so that the screw 6 connected to the linkage part can be rotated to meet the needs of movement.

[0048] As a further solution of the present invention, the linkage assembly includes a first bevel gear 7 fixedly connected to both ends of the screw 6, a second bevel gear 8 meshing with the first bevel gear 7, a bearing 9 whose inner ring is fixedly connected to the second bevel gear 8, and a first ball 10 rotatably engaged with the inner wall of the bearing 9;

[0049] The outer ring of the bearing 9 is fixedly connected to the top of the U-shaped frame 4 on the side away from the mounting frame 3, and the bearing 9 is concentrically arranged with the guide column 5;

[0050] The bearing 9 is sleeve-connected to the transmission assembly, and the first ball 10 is in sliding contact with the transmission assembly.

[0051] In this embodiment, when the transmission assembly moves up and down, it can drive the linkage assembly to move, thereby causing the second bevel gear 8 to rotate, and the first bevel gear 7 meshing with it to rotate synchronously, thereby causing the screw 6 fixedly connected to the first bevel gear 7 to rotate, thereby satisfying the driving use of the blowing structure, so that the blowing structure can blow and clean foreign matter on the lower mold base 1, ensuring the use effect.

[0052] As a further solution of the present invention, the transmission assembly includes four mounting rods 11 mounted on the four corners of the upper die base 2 by bolts, a driving rod 12 fixedly arranged in a vertical direction away from the end of the mounting rod 11 connected to the upper die base 2, a threaded groove 13 provided at the center of the driving rod 12, a vertical groove 14 opened on the upper die base 2 and connected to both ends of the threaded groove 13, and a guide hole 15 opened on the end of the driving rod 12 away from the mounting rod 11;

[0053] The driving rod 12 is slidably inserted between the inner ring of the bearing 9 and the center of the second bevel gear 8, and the first ball 10 is connected by rolling and contacting along the threaded groove 13 and the vertical groove 14;

[0054] The guide hole 15 is slidably plugged into the guide post 5 , and the guide post 5 is used to guide the guide hole 15 .

[0055] In this embodiment, when the upper mold base 2 moves in the vertical direction to close or open the mold, the mounting rod 11 installed on the upper mold base 2 will follow the movement, and the driving rod 12 on the mounting rod 11 is inserted into the inner ring of the bearing 9. The threaded groove 13 and the vertical groove 14 on the driving rod 12 conflict with the first ball 10. Therefore, when the driving rod 12 is inserted and moved inside the bearing 9, since the outer ring of the bearing 9 is fixed and the inner ring of the bearing 9 is movable, the inner ring of the bearing 9 can be rotated when the driving rod 12 is inserted and moved, thereby causing the second bevel gear 8 fixed to the inner ring of the bearing 9 to rotate, so that the transmission component can realize the use requirements of the linkage component transmission.

[0056] As a further solution of the present invention, the spiral directions of the threaded grooves 13 provided on the two groups of the driving rods 12 symmetrically arranged in the width direction of the upper die base 2 are opposite;

[0057] When the upper mold base 2 is closed or opened so that the vertical groove 14 moves to the position of the first ball 10, the bearing 9 remains in the disabled state;

[0058] When the threaded groove 13 moves to the position of the first ball 10 , the inner ring of the bearing 9 rotates as the first ball 10 moves along the trajectory of the threaded groove 13 .

[0059] In this embodiment, when the upper mold base 2 is closing or opening the mold, when the first ball 10 is in contact with the trajectory of the threaded groove 13 and the vertical groove 14, when the upper mold base 2 is opening the mold, the bottom height of the upper mold base 2 is lower than the height of the high-pressure air distribution pipe 16. At this time, the first ball 10 is in a state of contact with the vertical groove 14. When the upper mold base 2 is raised to a bottom height higher than the top height of the high-pressure air distribution pipe 16, the first ball 10 will contact with the threaded groove 13. At this time, the first ball 10 will move under the plug-in movement of the drive rod 12, thereby causing the bearing 9 to rotate. The bearing 9 can drive the above-mentioned second bevel gear 8 to rotate, thereby causing the screw 6 to rotate, satisfying the linkage use effect.

[0060] As a further solution of the present invention, when the inner ring of the bearing 9 rotates, the second bevel gear 8 rotates accordingly, and the first bevel gear 7 meshing with the second bevel gear 8 rotates synchronously;

[0061] When the first bevel gear 7 rotates, it rotates synchronously with the screw 6 fixed thereto.

[0062] In this embodiment, when the bearing 9 is driven to rotate by the transmission assembly, the second bevel gear 8 will rotate together. Since the second bevel gear 8 and the first bevel gear 7 are engaged, the vertical rotational force of the second bevel gear 8 is converted into the horizontal rotational force of the first bevel gear 7. The first bevel gear 7 is fixedly connected to the screw 6 so that the screw 6 can rotate. Since the threaded grooves 13 with opposite spiral directions are provided on the driving rods 12 at both ends of the screw 6, when the upper mold base 2 moves up and down so that the driving rod 12 is inserted into the inner ring of the bearing 9, it does not affect the driving of the driving rods 12 on both sides of the upper mold base 2, so that the screw 6 can be rotated and adjusted in a linked manner.

[0063] As a further solution of the present invention, L-shaped rods 19 are fixedly provided at both ends of the high-pressure gas distribution pipe 16. The L-shaped rods 19 are provided with sleeve holes, which are sleeved on the screw rod 6. A second ball 20 is rotatably fitted on the inner wall of the sleeve hole.

[0064] The second ball 20 slides in the thread groove on the screw 6. When the screw 6 rotates, the L-shaped rod 19 arranged above slides and displaces on the screw 6, thereby causing the high-pressure air distribution pipe 16 to move from one side to the other in the width direction of the lower mold base 1.

[0065] In this embodiment, when the screw 6 rotates, the L-shaped rod 19 fixedly connected at both ends of the high-pressure air distribution pipe 16 is sleeved on the screw 6, and the second ball 20 rotatably embedded in the inner wall of the L-shaped rod 19 contacts the groove opened on the screw 6. Therefore, when the screw 6 rotates, the L-shaped rod 19 sleeved on the screw 6 will slide, so the high-pressure air distribution pipe 16 will slide and adjust on the screw 6, and move along the width direction of the lower mold base 1. The nozzle 17 cooperates with the ejected air flow to blow away foreign matter on the lower mold base 1, thereby preventing foreign matter from entering the mold and affecting the effect of the metal material during mold closing and stamping.

[0066] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
