Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an anti-displacement mold for planetary gear forging. Background Technology

[0002] Planetary gears, as core components of mechanical transmission systems, are widely used in automotive differentials, robot joint reducers, and rail transportation. Their manufacturing precision directly affects transmission efficiency and service life.

[0003] Authorization Announcement No. CN 219966317 U: A planetary gear forging anti-displacement mold includes a fixed base. The top of the fixed base has a limiting groove, and the inner walls of both sides of the limiting groove are provided with locking parts. A forging mold overlaps the bottom of the limiting groove. Slide rails are provided on both sides of the forging mold, and scrapers are sleeved on the slide rails. A push rod is fixedly installed on the side of the scraper away from the forging mold, and a collection box is provided on the side of the forging mold away from the scraper. The beneficial effects of this utility model are: improved stability and firmness of the mold during use, and improved forging quality of planetary gears.

[0004] Although the above equipment can limit the mold of planetary gears, the elastic top contact block enters the mold to fix the mold of planetary gears. However, the elastic top contact block may loosen due to the forging impact, which will reduce the forging quality of the planetary gears. At the same time, when disassembling the mold of the elastic planetary gears, the personnel need to operate the elastic top contact block in different directions. Utility Model Content

[0005] In view of this, the present invention provides an anti-displacement mold for planetary gear forging. The present invention can facilitate operation by personnel in a uniform direction, while preventing loosening caused by forging impact.

[0006] To solve the above-mentioned technical problems, this utility model provides an anti-displacement mold for planetary gear forging, including a base plate, a mold shell on the upper surface of the base plate, a planetary gear mold inside the mold shell, and fixing components on both the mold shell and the planetary gear mold. The fixing components include strip-shaped opening slots on both sides of the mold shell and arc-shaped opening slots on both sides of the mold shell. A rotating rod is hinged to one side of the inner wall of the strip-shaped opening slot, and the arc surface of the rotating rod is located inside the arc-shaped opening slot. That is, after the operator puts the planetary gear mold into the mold shell, the rotating rod is rotated to move its arc surface along the trajectory of the arc-shaped opening slot. When the rotating rod rotates into the arc-shaped opening slot, the rotation of the rotating rod is stopped, thereby fixing and limiting the planetary gear mold, so that the arc surface of the rotating rod fits and contacts the arc-shaped opening slot, preventing loosening caused by forging impact, and facilitating operation by the operator in a unified direction.

[0007] The fixing components also include blocking buttons that are all set on the outer arc surface of the rotating rod; that is, the blocking buttons make it easier for personnel to rotate the rotating rod.

[0008] The fastener also includes an external thread on the outer arc surface of the rotating rod and an internal thread at the through hole of the blocking button; that is, the blocking button is rotated so that the side wall of the blocking button and the side end of the planetary gear mold form a contacting action, which indirectly provides a limiting fixation for the rotating rod.

[0009] The fasteners also include electromagnets installed inside the rotating rods, with arc-shaped opening slots serving as magnetic slots; that is, when the electromagnets are energized, they generate a magnetic field, which attracts the magnetic slot walls, generating an additional normal locking force.

[0010] The upper surface of the mold shell is provided with four limiting holes, and the bottom of the planetary gear mold is provided with four limiting pins, which are located in the four limiting holes; that is, the setting of the limiting pins and limiting holes facilitates the positioning and installation of the planetary gear mold inside the mold shell.

[0011] Both the planetary gear mold and the mold shell are made of medium carbon medium chromium steel; that is, the medium carbon content balances strength and toughness, thus adapting to the forging process of planetary gears.

[0012] The planetary gear mold is provided with planetary gear slots; this makes it easy to add the raw materials for making planetary gears into the planetary gear slots, thus facilitating the subsequent forging of planetary gears.

[0013] The base plate has four mounting holes, which facilitates the installation of the base plate on the forging machine body.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By rotating the stop button on the rotating rod, the side end of the stop button contacts the side end of the planetary gear mold, thus limiting the rotation rod. Then, the electromagnet inside the rotating rod is energized, causing it to attract to the magnetic groove of the arc-shaped opening slot. This improves the fixation of the rotating rod to the planetary gear mold and prevents loosening caused by forging impact. At the same time, when the stop button is rotated in the opposite direction, the electromagnet is de-energized, which indirectly releases the limitation of the rotating rod, making it easier to rotate the rotating rod and allowing personnel to operate in a unified direction.

[0015] 2. By inserting the limiting pin on the bottom of the planetary gear mold into the limiting hole inside the mold shell, the planetary gear mold can be quickly positioned. Attached Figure Description

Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0018] like Figure 1-3 As shown: This embodiment provides an anti-displacement mold for planetary gear forging, including a base plate 100. A mold shell 102 is provided on the upper surface of the base plate 100. The mold shell 102 is installed on the upper surface of the base plate 100. A planetary gear mold 103 is provided inside the mold shell 102. The side end of the planetary gear mold 103 is aligned with one side of the inner wall of the mold shell 102 for installation. Thus, the planetary gear mold 103 is used to add the raw material for making planetary gears into the mold, and then forge the raw material for planetary gears by forging or the like. Both the mold shell 102 and the planetary gear mold 103 are provided with fixing members 200. The fixing members 200 include those provided on the mold. The shell 102 has strip-shaped opening slots 202 on both sides, and arc-shaped opening slots 206 on both sides. The opening directions of the arc-shaped opening slots 206 and the strip-shaped opening slots 202 correspond one-to-one. A rotating rod 201 is hinged to one side of the inner wall of the strip-shaped opening slot 202. The arc surface of the rotating rod 201 is located inside the arc-shaped opening slot 206. By rotating the rotating rod 201, the rotating rod 201 enters the arc-shaped opening slot 206. Then the rotating rod 201 stops rotating, so that the arc surface of the rotating rod 201 fits and touches the arc-shaped opening slot 206, preventing loosening caused by forging impact, and facilitating operation by personnel in a unified direction. Fastener 200 Figure 2 As shown, The fixing component 200 also includes blocking buttons 203 that are all disposed on the outer arc surface of the rotating rod 201; The fastener 200 also includes an external thread 205 provided on the outer arc surface of the rotating rod 201, and an internal thread provided at the through hole of the blocking button 203; The blocking button 203 rotates on the rotating rod 201, causing the side end of the blocking button 203 to contact the side end of the planetary gear mold 103, thereby achieving the function of limiting the rotating rod 201. At the same time, when the blocking button 203 rotates in the opposite direction, it can indirectly release the limitation of the rotating rod 201, thus facilitating the rotation of the rotating rod 201.

[0019] The fastener 200 also includes an electromagnet 204 disposed inside the rotating rod 201. The electromagnet 204 is installed inside the rotating rod 201, and the arc-shaped opening slot 206 is a magnetic slot; that is, when the electromagnet 204 is energized, it generates a magnetic field, which forms an attractive force with the wall of the magnetic slot, generating an additional normal locking force.

[0020] Four limiting holes 105 Figure 2 and Figure 3 As shown, The upper surface of the mold shell 102 is provided with four limiting holes 105, and the bottom of the planetary gear mold 103 is provided with four limiting posts 106. The four limiting posts 106 are located in the four limiting holes 105, which makes it easy to install the planetary gear mold 103 in the mold shell 102 and can quickly position the planetary gear mold 103. Planetary gear mold 103 Figure 1 As shown, Both the planetary gear mold 103 and the mold shell 102 are made of medium carbon medium chromium steel. The medium carbon content balances strength and toughness, thus adapting to the forging process of planetary gears. The planetary gear mold 103 is provided with a planetary gear groove 104, which makes it easy to add the raw materials for making planetary gears into the planetary gear groove 104, indirectly facilitating the subsequent forging of planetary gears. The base plate 100 is provided with four mounting holes 101, which facilitates the installation of the base plate 100 on the forging machine body; Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
