Description

Technical Field

[0001] This utility model relates to the field of gear forging, and in particular to a truck gear forging die that is easy to inspect and maintain. Background Technology

[0002] Truck gears, as core components of the transmission system, must withstand harsh conditions such as high-frequency impacts and heavy-load friction, requiring extremely high forming precision and structural strength. Gear forging dies, as key equipment in gear forming, directly determine the processing quality and production efficiency of the gears.

[0003] In large-scale production scenarios, molds need to withstand high temperature and high pressure environments for a long time. The cavity is prone to wear, scratches, cracks and other damage. Regular disassembly, inspection, grinding and maintenance or replacement of parts are required to avoid an increase in the defect rate of gears due to mold failure.

[0004] Traditional truck gear forging dies often use a multi-bolt fastening method for installation, resulting in a complex connection structure between the die and the equipment. Disassembly requires loosening each bolt individually, and some bolts are prone to corrosion and jamming due to high temperatures. This not only requires multiple people to work together but also necessitates the use of specialized tools, leading to a lengthy disassembly and assembly process for each maintenance, which seriously affects production continuity. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a truck gear forging die that is convenient for inspection and maintenance, aiming to improve the problems of "cumbersome disassembly and assembly process and low maintenance efficiency" in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a truck gear forging mold that is convenient for inspection and maintenance, comprising an upper mold and a lower mold. An installation mechanism is provided at the upper part of the upper mold and the lower part of the lower mold. The installation mechanism includes a pin and a mounting base. The pin is fixedly connected to the upper part of the upper mold. The outer side of the pin is provided with staggered slots. The pin is inserted into the inner wall of the mounting base. Two sets of limiting members are rotatably provided on the inner wall of the mounting base. Limiting grooves are provided through the outer side of the limiting members. The limiting grooves engage with the slots. Positioning components are fixedly connected to the left side of each set of limiting members. A bidirectional screw is threaded through the inner wall of the positioning component. A limiting component for positioning the bidirectional screw is provided on the left side of the mounting base.

[0007] As a further description of the above technical solution: the positioning component includes a fixed rod, which is fixedly connected to the left side of the limiting member. A movable rod is movably connected to the inner wall of the left side of the fixed rod. A connecting seat is rotatably connected to the left side of the movable rod. A bidirectional screw is threadedly connected to the inner wall of the connecting seat. A connecting rod is fixedly connected to the left side of the mounting seat. The bidirectional screw is rotatably connected to the inner wall of the connecting rod.

[0008] As a further description of the above technical solution: the limiting component includes a housing, the housing is fixedly connected to the upper part of the connecting rod, a positioning element is slidably connected through the inner wall of the housing, an anti-slip groove is provided on the outer side of the bidirectional screw near the connecting rod, the lower part of the positioning element is engaged with the anti-slip groove, and the housing and the positioning element are elastically connected by a spring.

[0009] As a further description of the above technical solution: a support member is provided on the outer side of the positioning member, and a cylindrical protrusion is provided on the outer side of the positioning member, and the cylindrical protrusion of the positioning member slides on the inner wall of the groove of the support member.

[0010] As a further description of the above technical solution: the upper part of the positioning member is provided with a T-shape.

[0011] As a further description of the above technical solution: the two sets of limiting members are arranged alternately, one above the other.

[0012] As a further description of the above technical solution: regular hexagonal blocks are fixedly connected to both the front and rear sides of the bidirectional screw.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by using the installation mechanism, when it is necessary to disassemble the mold, it is only necessary to rotate the bidirectional screw, which engages with the threaded connection seat in the positioning component, and will drive the movable rod to slide along the inner wall of the fixed rod, thereby pulling the two sets of limiting parts to rotate synchronously, so that the limiting groove on the limiting part disengages from the slot on the outside of the plug pin. At this time, the upper mold or lower mold along with the plug pin can be directly pulled out from the mounting seat. It can be operated by a single person, which significantly shortens the disassembly and assembly time during maintenance.

[0014] 2. In this utility model, the outer shell and the positioning component are elastically connected by a spring in the limiting component. The spring always applies downward elastic pressure to the positioning component, so that the lower part of the positioning component is continuously engaged with the anti-slip groove of the bidirectional screw, reducing the risk of the limiting component loosening or the groove separating from the limiting groove due to vibration, and ensuring the installation stability of the mold throughout the entire working cycle.

[0017] 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.

[0018] Reference Figure 1 , 2 and Figure 6 This utility model provides an embodiment of a truck gear forging die that is easy to inspect and maintain. It includes an upper die 1 and a lower die 2, directly participating in the forging and forming of truck gears. It serves as a direct forming carrier for the gear's outline and dimensional accuracy. Both the upper part of the upper die 1 and the lower part of the lower die 2 are provided with mounting mechanisms 3. The mounting mechanisms 3 are bolted to the press and worktable. The lower mounting mechanism 3 has a through hole and includes a pin 31 and a mounting base 33. The pin 31 is fixedly connected to the upper part of the upper die 1, serving as the connection between the die and the mounting base 33. The connecting carrier is embedded into the inner wall of the mounting base 33 via a plug-in method to achieve initial positioning of the mold. The outer side of the plug pin 31 is provided with staggered slots 32, which engage with the limiting slots 36 to form a fixed locking point for the mold. The staggered slots 32 can cooperate with two sets of staggered limiting members 35 to constrain and position from multiple directions, avoiding radial displacement. The plug pin 31 is inserted into the inner wall of the mounting base 33. The mounting base 33 provides the insertion space for the plug pin 31 and the installation support for the limiting members 35. It is a transition component for connecting the mold to external equipment, ensuring the stability of the mold after installation. Reference Figures 2-4The inner wall of the mounting base 33 is rotatably equipped with two sets of limiting members 35. The two sets of limiting members 35 are staggered vertically and engage with the slot 32 of the insertion pin 31 through the limiting groove 36 to achieve final fixation of the mold. The two sets of staggered layout can constrain the insertion pin 31 from different heights and angles to avoid axial movement and radial displacement. The outer side of the limiting member 35 has a limiting groove 36 that runs through it. By engaging with the slot 32, the insertion pin 31 is locked in the mounting base 33 to prevent loosening during mold operation. The limiting groove 36 and the slot 32 engage with each other. The left side of each of the two sets of limiting members 35 is fixedly connected with a positioning component 34. The inner wall of the positioning component 34 is threaded with a bidirectional screw 37. By rotating, the two sets of connecting seats 343 move synchronously in opposite directions, thereby controlling the opening and closing of the limiting member 35. The movable rod 342 is driven to slide through the threaded transmission, which drives the limiting member 35 to rotate, thus completing the engagement or unlocking. The left side of the mounting base 33 is provided with a limiting component 38 for positioning the bidirectional screw 37.

[0019] Reference Figures 3-5 The positioning component 34 includes a fixed rod 341, which is fixedly connected to the left side of the limiting member 35, connecting the limiting member 35 and the movable rod 342. It provides rigid support for the limiting member 35, ensuring that the driving force of the movable rod 342 can be accurately transmitted to the limiting member 35, causing it to rotate stably. The movable rod 342 is movably connected to the inner left side of the fixed rod 341. The left side of the movable rod 342 is U-shaped to support the connecting seat 343, compensating for displacement deviations when the bidirectional screw 37 rotates. It adapts to the movement trajectory of the connecting seat 343 through sliding and rotation, avoiding... To prevent interference between components and ensure precise resetting and locking of the limiting component 35, the left side of the movable rod 342 is rotatably connected to the connecting seat 343, which converts the rotational motion of the bidirectional screw 37 into linear motion. Through threaded engagement, the movable rod 342 slides left and right, thereby driving the limiting component 35 to rotate. The bidirectional screw 37 is threadedly connected to the inner wall of the connecting seat 343. The left side of the mounting base 33 is fixedly connected to the connecting rod 344, which provides rotational support for the bidirectional screw 37 and ensures its coaxiality during rotation. The bidirectional screw 37 is rotatably connected to the inner wall of the connecting rod 344.

[0020] Reference Figure 3 and Figure 5The limiting component 38 includes a housing 381, which is fixedly connected to the upper part of the connecting rod 344. The housing 381 provides installation space and protection for the positioning member 382 and the spring 384, constraining the movement direction of the positioning member 382 to ensure it can only slide up and down. The positioning member 382 is slidably connected through the inner wall of the housing 381. The lower part engages with the anti-slip groove 383 to lock the bidirectional screw 37, preventing it from rotating during operation. The bidirectional screw 37 has an anti-slip groove 383 on its outer side near the connecting rod 344, increasing the contact friction between the positioning member 382 and the bidirectional screw 37. The engagement structure restricts the rotational freedom of the bidirectional screw 37, preventing loosening due to vibration. The lower part of the positioning member 382 engages with the anti-slip groove 383. The housing 381 and the positioning member 382 are elastically connected by the spring 384, applying downward elastic pressure to the positioning member 382 to ensure that the lower part of the positioning member 382 is continuously embedded in the anti-slip groove 383, achieving automatic locking. A support member 385 is provided on the outer side of the positioning member 382. A cylindrical protrusion is provided on the outer side of the positioning member 382. The cylindrical protrusion of the positioning member 382 slides on the inner wall of the groove of the support member 385, constraining the position of the positioning member 382 after sliding, thereby facilitating the operation of rotating the bidirectional screw 37. A T-shape is provided on the upper part of the positioning member 382 for easy manual pulling to unlock. Regular hexagonal blocks are fixedly connected to both the front and rear sides of the bidirectional screw 37.

[0021] Working principle: During installation, the upper mold 1 and lower mold 2 are first inserted into the inner wall of the corresponding mounting base 33 through their upper and lower insertion pins 31 to complete the initial positioning. Then, the T-shaped positioning member 382 in the limiting assembly 38 is pulled upward, so that its lower part is disengaged from the anti-slip groove 383 of the bidirectional screw 37, and the spring 384 is compressed. With the help of the regular hexagonal blocks at both ends of the bidirectional screw 37, the bidirectional screw 37 is rotated with a tool. Its threaded engagement with the connecting base 343 in the positioning assembly 34 will drive the two sets of connecting bases 343 to move synchronously in opposite directions, thereby driving the movable rod 342 to slide along the inner wall of the fixed rod 341, pulling the two sets of upper and lower staggered limiting members 35 to rotate inward, so that the limiting groove 36 on the limiting member 35 is precisely engaged with the staggered slot 32 on the outside of the insertion pin 31.

[0022] When the positioning component 382 is released, the spring 384 returns to its elastic deformation, pushing the positioning component 382 downward to reset. Its lower part is embedded in the anti-slip groove 383. At the same time, the cylindrical protrusion on the outside of the positioning component 382 slides along the groove of the support component 385, ensuring that the positioning component 382 stably locks the bidirectional screw 37, preventing it from rotating, thus completing the firm installation of the mold and ensuring the positioning accuracy during mold closing forging.

[0023] When maintenance is required, pull the positioning piece 382 upwards again to unlock the bidirectional screw 37. Rotate the bidirectional screw 37 in the opposite direction to drive the two sets of connecting seats 343 to separate in the opposite direction. The movable rod 342 pushes the limiting piece 35 to rotate outwards, causing the limiting groove 36 to disengage from the slot 32. At this time, the upper mold 1 or lower mold 2, along with the insertion pin 31, can be directly pulled out from the mounting base 33 without disassembling other fixing parts. A single person can quickly complete the disassembly, facilitating the inspection and replacement of mold cavities or parts.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
