Description

Technical Field

[0001] This utility model relates to the field of hardware processing, and in particular to a flipping device for hardware stamping dies. Background Technology

[0002] Hardware products, also known as "small hardware," refer to various metal parts made from metals such as iron, steel, and aluminum through physical processing such as forging, rolling, and cutting. Stamping dies are special process equipment used in cold stamping to process materials into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies installed on a press at room temperature to apply pressure to materials, causing them to separate or plastically deform, thereby obtaining the desired parts. When producing dies, the dies need to be flipped for further processing.

[0003] A search of Chinese patents revealed publication number CN216263129U: a molding die flipping mechanism, comprising a base, a fixed part of a telescopic device fixedly connected to the upper middle position of the base, a movable part of the telescopic device fixedly connected to a box for storing lubricating oil, a U-shaped plate with an arc shape fixedly connected to the upper end of the box and positioned between two transmission gears, an arc-shaped toothed plate fixedly connected to the bottom inside the U-shaped plate and meshing with an arc-shaped rack, the arc-shaped rack being arranged through the U-shaped plate. This design utilizes an electric push rod to drive the box, U-shaped plate, and arc-shaped toothed plate to move upward, causing the arc-shaped toothed plate to mesh with the arc-shaped rack, thereby restricting the arc-shaped rack and effectively counteracting the force applied by the arc-shaped mounting block and the molding die made of anti-radar honeycomb material, preventing damage to the arc-shaped rack and transmission gears, improving service life, and providing good stability.

[0004] Existing flipping devices lack a fixing function. Generally, when flipping a mold, the mold is placed directly on the device. During the flipping process, the mold slides under gravity, causing it to collide with the device, which can easily damage the mold. This makes the device inconvenient to use and difficult to remove. Typically, when flipping a mold, the mold is mechanically placed on the outside of the device, and then manually moved to the inside of the flipping device to make it fit snugly against the surface. After flipping, the mold is manually moved to the outside again for mechanical removal. This process is cumbersome, increases workload, and reduces work efficiency. To solve the above problems, we propose a flipping device for metal stamping dies. Utility Model Content

[0005] The purpose of this utility model is to provide a flipping device for stamping dies of hardware parts, which has the advantages of fixing function and easy mold handling.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flipping device for stamping dies of hardware parts, including a base, a plurality of support wheels rotatably connected to the inner wall of the base, a circular outer shell rollingly connected to the surface of the support wheels, a driving mechanism provided at the bottom of the circular outer shell, a fixed shell bolted to the inner wall of the circular outer shell, a partition bolted to the inner wall of the fixed shell, four screws rotatably sleeved between the inner wall of the partition and the inner wall of the fixed shell, a lifting plate threaded to the surface of the screws, a lifting rod bolted to the bottom of the lifting plate, and the lifting rod slidingly sleeved with the inner wall of the fixed shell, a synchronous wheel fixedly sleeved to the top of the screws, a synchronous belt drivingly connected to the surface of the synchronous wheel, and a first motor connected to the top of the screws on the left side of the front through a coupling, and the first motor bolted to the top of the fixed shell.

[0007] By adopting the above technical solution, the rotation of the first motor causes the screw to drive the synchronous pulley, which in turn drives the synchronous belt to rotate. The rotation of the synchronous belt causes the other screws to rotate, and the rotation of the screws drives the lifting plate, which in turn drives the lifting rod to lower the top conveyor roller, thus pressing the mold. This method can achieve the purpose of fixing the mold, ensuring the stability of the mold's rotation and improving its practicality.

[0008] The present invention is further configured such that: a conveying seat is bolted to the bottom of the lifting rod and the surface of the circular outer shell; a second motor is bolted to the surface of the conveying seat; the output end of the second motor extends into the interior of the conveying seat and is connected to a worm gear via a coupling; the other end of the worm gear is rotatably connected to the inner wall of the conveying seat; multiple worm wheels mesh with the surface of the worm gear; a conveying roller is fixedly sleeved at the axis of the worm wheel; and the conveying roller is rotatably sleeved with the inner wall of the conveying seat.

[0009] By adopting the above technical solution, the mold is placed on the bottom conveyor roller by using a machine, and the second motor is turned on to make the worm gear drive the worm wheel to rotate. The rotation of the worm wheel drives the conveyor roller to move the mold to the inside and make it stick to the rubber pad. This method can facilitate the picking and placing of the mold, reduce the workload, and improve the efficiency of work.

[0010] The present invention is further configured such that: the driving mechanism includes a reducer, the reducer is bolted to the surface of the base, a third motor is installed on the top of the reducer, the output end of the reducer extends into the interior of the base and is connected to a transmission shaft via a coupling, and the other end of the transmission shaft is rotatably connected to the inner wall of the base, and two gears are fixedly sleeved on the surface of the transmission shaft, the surface of the gears is meshed with a toothed ring, and the toothed ring is bolted to the surface of the circular outer shell.

[0011] By adopting the above technical solution, a drive mechanism is set up so that the motor rotates and drives the reducer to rotate, the reducer rotates and drives the gear on the transmission shaft to rotate, and the gear rotates so that the gear ring drives the circular outer shell to rotate, which facilitates the flipping of the mold.

[0012] The present invention is further configured such that a rubber pad is bolted to the surface of the circular outer shell.

[0013] By adopting the above technical solution, rubber pads are set to prevent the mold from colliding with the circular outer shell, thus protecting the mold.

[0014] The present invention is further configured such that: the inner wall of the base and the inner wall of the conveyor seat are both bolted with a fixing plate, and the transmission shaft and the worm gear are rotatably sleeved with the fixing plate.

[0015] By adopting the above technical solution, the drive shaft and worm gear are fixed by setting a fixing plate, thereby improving stability.

[0016] The present invention is further configured such that: a pressure roller is rotatably connected to the inner wall of the base, and the pressure roller is in rolling connection with the surface of the circular outer shell.

[0017] By adopting the above technical solution, pressure rollers are set to press the circular outer shell, thereby improving stability.

[0018] The present invention is further configured such that a limiting plate is bolted to the surface of the circular outer shell.

[0019] By adopting the above technical solution, a limit plate is set to prevent the circular outer shell from rotating excessively, thereby improving stability.

[0020] The present invention is further configured such that the conveying roller is a rubber roller.

[0021] By adopting the above technical solution, rubber rollers are used for the conveyor rollers. Rubber rollers have a good anti-slip effect and will not damage the mold.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model achieves the purpose of fixing the mold by rotating the first motor to drive the screw to drive the synchronous pulley to drive the synchronous belt to rotate, the synchronous belt to drive the other screws to rotate, and the screw rotation to drive the lifting plate to drive the lifting rod to drive the top conveyor roller to descend, thereby pressing the mold.

[0034] Brief description of the operation: Using mechanical equipment, the mold is placed on the bottom conveyor roller 17. The second motor 14 is turned on, causing the worm gear 15 to rotate. The worm gear 15 rotates, which in turn rotates the worm wheel 16. The worm wheel 16 rotates, which in turn rotates the conveyor roller 17. The rotating conveyor roller 17 transports the mold to the inside of the device, where it is pressed tightly against the rubber pad 23. Then, the first motor 12 rotates, causing the screw 7 to rotate. The screw 7 rotates, which in turn rotates the synchronous pulley 10. The synchronous pulley 10 rotates, which in turn rotates the synchronous belt 11. The synchronous belt 11 rotates, which in turn rotates the other synchronous pulleys 10, causing the other screws 7 to rotate. The rotating screws 7 cause the lifting plate 8 to descend, which in turn causes the lifting rod 9 to descend, which in turn lowers the top conveyor... Roller 17 descends, pressing and fixing the mold. Then, the third motor 19 is turned on. The rotation of the third motor 19 drives the transmission shaft 20 to rotate, which in turn drives the gear 21 to rotate. The gear 21 then drives the gear ring 22 to rotate, which in turn causes the circular outer shell 3 to rotate. The rotation of the circular outer shell 3 causes the mold to rotate, flipping the mold 180 degrees. After the mold is flipped into place, the top conveyor roller 17 is at the bottom, and the third motor 19 stops rotating. Then, the first motor 12 reverses, causing the conveyor roller 17 to move the rubber and loosen the pressure on the mold. The second motor 14 reverses, causing the conveyor roller 17 to transport the mold to the outside of the device. The mold is then removed using mechanical equipment, thus facilitating the removal and placement of the mold.
