Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a steering processing device. Background Art

[0002] Usually, the mold consists of two parts: the upper mold and the lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed by molds.

[0003] When the existing cylindrical workpiece is rotationally punched, it is necessary to put it on the rotating die, then use a fixing component to tighten it, and then use the stamping upper die to perform intermittent punching. After each punching, the driving device is required to drive the rotating die to turn and change the punching position of the cylindrical workpiece on the rotating die. It cannot use the moving potential energy of the stamping upper die to rotate, which causes the rotary die to consume a certain amount of electrical energy each time it turns, increasing the overall energy consumption and also increasing the workpiece processing cost. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a steering processing device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a steering processing device, including a stamping upper die, a die base is provided under the stamping upper die, and a rotating die is rotatably connected to one side of the outer surface of the die base; a telescopic lifting frame is fixedly installed between the stamping upper die and the die base, and a rack is fixedly installed on one side of the outer surface of the telescopic lifting frame; a mounting shaft is fixedly installed on one side of the outer surface of the die base, and the outer surface of the mounting shaft is rotatably connected to a limited transmission assembly, and the limited transmission assembly and the rack are matched; a rotating assembly is installed between the rotating mold and the limited transmission assembly.

[0006] Furthermore, the telescopic lifting frame includes an L-shaped rod, and the L-shaped rod is fixedly installed on one side of the outer surface of the stamping upper mold, the outer surface of the L-shaped rod is sleeved with an outer frame, and the rack is fixedly installed on one side of the outer surface of the outer frame, and the inner walls on both sides of the outer frame are slidably connected with a lifting plate fixedly connected to the L-shaped rod, and the outer frame and the lifting plate are slidably connected, so that the lifting plate and the outer frame are limited to each other, thereby ensuring the stability of the movement of the outer frame.

[0007] Furthermore, an elastic rope is fixedly connected between the bottom of the outer frame and the mold base, and the provision of the elastic rope is conducive to driving the outer frame to reset.

[0008] Furthermore, the limit transmission assembly includes a first gear, and the first gear is rotatably sleeved on the outer surface of the mounting shaft and meshingly connected with the rack. A stop block is fixedly connected to one side of the outer surface of the first gear, and the setting of the stop block is conducive to the first gear driving the second gear to rotate.

[0009] Furthermore, the limit transmission assembly also includes a second gear, and the second gear is rotatably mounted on the outer surface of the mounting shaft. The outer surface of the second gear is fixedly connected to the limit seat on one side close to the first gear. The inner walls on both sides of the limit seat are rotatably connected to the limit plate. One side of the limit plate is in contact with the inner wall of the limit seat. When the limit plate is subjected to force from the other side, the limit seat can be driven to move, thereby driving the second gear to rotate.

[0010] Furthermore, a torsion spring is fixedly installed at the rotation connection between the limit plate and the limit seat, and the provision of the torsion spring is conducive to resetting the limit plate.

[0011] Furthermore, the rotating assembly includes a large gear, and the large gear is meshed with the second gear. The inner surface of the large gear is fixedly connected with a rotating shaft, and the rotating shaft passes through the mold base and is fixedly connected to the rotating mold. One side of the outer surface of the large gear is abutted with a wear-resistant rubber block, and the wear-resistant rubber block is fixedly connected to the mold base. When the first gear rotates counterclockwise, the stopper also rotates counterclockwise. Because the wear-resistant rubber block generates rotational resistance to the large gear, it generates rotational resistance to the second gear, and the resistance is greater than the elastic force of the torsion spring. Therefore, after the counterclockwise rotating stopper contacts the limit plate, it will not drive the second gear to rotate.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the steering processing device can utilize the kinetic energy of the stamping upper die when it rises to drive the rotating die to rotate through the telescopic lifting frame, rack, limit transmission assembly and rotating assembly, without the need for an additional driving device. This can not only reduce manufacturing costs and driving energy consumption, but also reduce kinetic energy waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, it involves a steering processing device, including a stamping upper die 1, a die base 4 is provided below the stamping upper die 1, and a rotating die 3 is rotatably connected to one side of the outer surface of the die base 4 to form a complete stamping die, which is conducive to punching processing of cylindrical workpieces.

[0023] A telescopic lifting frame is fixedly installed between the stamping upper die 1 and the die base 4, and the telescopic lifting frame includes an L-shaped rod 2, and the L-shaped rod 2 is fixedly installed on one side of the outer surface of the stamping upper die 1, the outer surface of the L-shaped rod 2 is sleeved with an outer frame 6, and the rack 8 is fixedly installed on one side of the outer surface of the outer frame 6, and the inner walls on both sides of the outer frame 6 are slidably connected with a lifting plate 5 fixedly connected to the L-shaped rod 2, and an elastic rope 7 is fixedly connected between the bottom of the outer frame 6 and the die base 4. The setting of the outer frame 6 and the lifting plate 5 can form a stroke difference when the L-shaped rod 2 rises, thereby preventing the rotating die 3 from rotating while the stamping upper die 1 rises, thereby causing the workpiece to be damaged by collision.

[0024] A mounting shaft 10 is fixedly mounted on one side of the outer surface of the mold base 4, and the outer surface of the mounting shaft 10 is rotatably connected to a limited transmission assembly, the limited transmission assembly includes a first gear 14, and the first gear 14 is rotatably sleeved on the outer surface of the mounting shaft 10 and meshed with the rack 8, a stopper 16 is fixedly connected to one side of the outer surface of the first gear 14, and the limited transmission assembly also includes a second gear 9, and the second gear 9 is rotatably sleeved on the outer surface of the mounting shaft 10, and the outer surface of the second gear 9 is close to one side of the first gear 14 The limiting seat 15 is fixedly connected, and the inner walls on both sides of the limiting seat 15 are rotatably connected to the limiting plate 17. A torsion spring is fixedly installed at the rotation connection between the limiting plate 17 and the limiting seat 15. One side of the limiting plate 17 is in contact with the inner wall of the limiting seat 15. When the limiting plate 17 is subjected to the force from the other side, the limiting seat 15 can be driven to move. When the limiting plate 17 receives the force from the same side, the limiting plate 17 will be driven to rotate by the contact. The force on the limiting seat 15 is small, and the torsion spring can assist in resetting the limiting plate 17 that has undergone rotational displacement.

[0025] A rotating assembly is installed between the rotating mold 3 and the limiting transmission assembly. The rotating assembly includes a large gear 11, and the large gear 11 is meshed with the second gear 9. The inner surface of the large gear 11 is fixedly connected with a rotating shaft 12, and the rotating shaft 12 passes through the mold base 4 and is fixedly connected to the rotating mold 3. A wear-resistant rubber block 13 is abutted on one side of the outer surface of the large gear 11, and the wear-resistant rubber block 13 is fixedly connected to the mold base 4. The wear-resistant rubber block 13 generates rotational resistance to the large gear 11, and thus generates rotational resistance to the second gear 9. The resistance is greater than the elastic force of the torsion spring. Therefore, after the counterclockwise rotating block 16 contacts the limiting plate 17, it will not drive the second gear 9 to rotate.

[0026] Working principle: First, install the whole fixed on the punching machine, and then fix the workpiece. After a punching is completed, the punching upper die 1 rises under the action of the punching machine. When the punching upper die 1 rises, it drives the L-shaped rod 2 to rise. When the lifting plate 5 also rises along the outer frame 6, when the lifting plate 5 contacts the inner top of the outer frame 6, the outer frame 6 also rises. The outer frame 6 drives the rack 8 to rise. After the rack 8 contacts the first gear 14, it drives the first gear 14 to rotate clockwise. When the stopper 16 contacts the limit plate 17, the first gear 14 drives the second gear 9 to rotate, and the second gear 9 drives the large gear 11 to rotate slightly. The rotating shaft 12 drives the rotating mold 3 to rotate a certain angle. When the stamping upper mold 1 descends, the L-shaped rod 2 drives the lifting plate 5 to descend, and the outer frame 6 descends under the action of the elastic rope 7. The outer frame 6 drives the rack 8 to descend, and the rack 8 drives the first gear 14 to rotate counterclockwise. At this time, the stopper 16 rotates counterclockwise, and because the wear-resistant rubber block 13 produces rotational resistance to the large gear 11, it produces rotational resistance to the second gear 9, and its resistance is greater than the elastic force of the torsion spring. Therefore, after the counterclockwise rotating stopper 16 contacts the limit plate 17, it will not drive the second gear 9 to rotate. At this time, the rotating mold 3 will not rotate and normal punching can be achieved.
