Description

Technical Field

[0001] This invention relates to the field of zinc diffusion equipment, and more specifically, to an in-furnace transfer drive device for zinc diffusion equipment. Background Technology

[0002] Powder zinc diffusion treatment is one of the widely used anti-corrosion methods for bullet clips. It involves a diffusion reaction on the surface of the clip to form a zinc-diffused layer, which possesses excellent density, toughness, corrosion resistance, and wear resistance.

[0003] In the zinc diffusion process, the spring needs to be buried in a sealed tank containing zinc powder and heated. During this process, the tank rotates to ensure that the zinc powder and the spring come into uniform contact.

[0004] Traditional zinc diffusion equipment typically includes a zinc diffusion furnace and a sealed tank. After the springs are bundled together, they are placed into the sealed tank, and then zinc powder is added to the sealed tank. The whole process is then placed in the zinc diffusion furnace and rotated for zinc diffusion. This process is cumbersome, cannot achieve continuous zinc diffusion, and results in products with poor uniformity in quality and performance, as well as low zinc diffusion efficiency. Summary of the Invention

This in-furnace transfer drive device can push the zinc diffusion pot from the inlet to the outlet according to the station, and stay at each station for a certain period of time. The total residence time of each zinc diffusion pot in the furnace is equal to the process specified time. It can also drive the zinc diffusion pot it carries to rotate axially, thereby improving the zinc diffusion effect.

[0006] To achieve the above objectives, the present invention provides an in-furnace conveying drive device for a zinc diffusion equipment.

Detailed Implementation

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] In this invention, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0026] See Figure 1-2 The furnace in-furnace transfer drive device shown in the zinc diffusion equipment includes: a stepping lifting mechanism, a fixed support frame 14, and a rotating support mechanism. The upper part of the stepping lifting mechanism is provided with a lifting platform 12, and multiple positioning slots are arranged along its length on the lifting platform 12. The fixed support frame 14 is located above the stepping lifting mechanism. The two ends of the rotating support mechanism are installed on both sides of the fixed support frame 14 and are used to support the zinc diffusion tank 7 and drive the zinc diffusion tank 7 to rotate axially. A passage gap is formed in the middle of the rotating support mechanism for the passage of the lifting platform 12.

[0027] Through the implementation of the above technical solution, the furnace in-process transmission drive device can push the zinc diffusion pot 7 from the inlet to the outlet according to the station, and stay at each station for a certain period of time. The total residence time of each zinc diffusion pot 7 in the furnace is equal to the process specified time. It can also drive the zinc diffusion pot 7 it carries to rotate axially, thereby improving the zinc diffusion effect.

[0028] During the zinc diffusion process, a continuous conveying process is achieved from the inlet to the outlet of the zinc diffusion tank. As a result of the continuous conveying, the quality uniformity of the zinc-dipped products is good and the zinc diffusion efficiency is high.

[0029] Because multiple zinc-diffusion pots 7 can be placed in the large zinc-diffusion furnace at the same time, and the zinc-diffusion pots 7 can be automatically ejected, the performance consistency of products in the same batch is good.

[0030] After being pushed out of the furnace, the zinc-diffused tank 7 is unloaded outside the furnace and then automatically transported back to the inlet position for reuse via a chain conveyor outside the furnace.

[0031] In practical use, the lifting platform 12 is lifted by the stepping lifting mechanism and then moved horizontally towards the outlet position. It then moves downwards and returns horizontally, allowing multiple zinc-distillation tanks 7 to be simultaneously pushed into one storage position. At this time, the rotating bearing mechanism at the inlet position is vacated, and the zinc-distillation tanks 7 to be zinc-distilled are sent onto the vacated rotating bearing mechanism by a hoisting device. This repetitive motion allows multiple zinc-distillation tanks 7 to move from the inlet to the outlet position of the zinc-distillation furnace 9 according to a preset rhythm. Multiple temperature zones can be set along the length of the zinc-distillation furnace 9 to continuously complete the process requirements of different temperature zones. Furthermore, since each zinc-distillation tank 7 experiences the same zinc-distillation time and temperature, the resulting elastic strip product has stable quality. Simultaneously, the zinc-distillation tanks 7 can rotate axially during the zinc-distillation process, ensuring more thorough zinc distillation.

[0032] In this embodiment, in order to further provide a stepping lifting mechanism that enables the zinc plating tank 7 to have a better propulsion effect, the stepping lifting mechanism includes: a first-layer frame 3 and a second-layer frame 5. The bottom of the first-layer frame 3 is connected to a lifting mechanism that drives its vertical movement. The second-layer frame 5 is connected to a second-layer drive 11 that drives its horizontal sliding movement. The first-layer frame 3 and the second-layer frame 5 are slidably connected. The lifting platform 12 is disposed on the top of the second-layer frame 5. When the stepping lifting mechanism is working, it first lifts the first-layer frame 3, and then lifts the second-layer frame 5, so that the positioning slots on the lifting platform 12 are engaged with the zinc-distillation tanks 7 one by one. Then, the second-layer drive 11 pushes the second-layer frame 5 towards the outlet direction to advance all the zinc-distillation tanks 7 into a storage position. Then, the lifting mechanism drives the second-layer frame 5 to move downward. At this time, the zinc-distillation tanks 7 fall on the corresponding rotating bearing mechanism to continue rotating zinc-distillation. At this time, the zinc-distillation tank 7 at the front end is removed from the zinc-distillation furnace 9 and lifted away by the hoisting equipment to proceed to the next process. The empty rotating bearing mechanism at the rear end is loaded with a new zinc-distillation tank 7 by the hoisting equipment.

[0033] In this embodiment, to further provide a lifting mechanism, the lifting mechanism includes: multiple inclined rails 2 disposed on both sides of a first-layer frame 3; multiple rollers 4 disposed on the inclined surfaces of the inclined rails 2 on both sides of the first-layer frame 3; and a first-layer drive 1 connected to the first-layer frame 3 for pushing it to move laterally. In use, the first-layer drive 1 pushes the first-layer frame 3 to move laterally, causing the first-layer frame 3 to rise and fall under the guidance of the multiple inclined rails 2. Then, through the transmission effect of the rollers 4, the second-layer frame 5 is pushed upward, or when the first-layer drive 1 is retracted, the second-layer frame 5 descends under the action of gravity.

[0034] In this invention, the first-layer drive 1 and the second-layer drive 11 are hydraulic telescopic rods, electric telescopic rods, or pneumatic telescopic rods, and the connection at both ends is through hinges.

[0035] In this embodiment, the ramp track 2 is fixedly installed on the bottom support panel 13, the first-layer drive 1 is installed on the upper surface of the bottom support panel 13, and the second-layer drive 11 is installed on the front or rear side of the bottom support panel 13. The bottom support panel 13 allows for better and more stable installation of the first-layer drive 1 and the second-layer drive 11, resulting in better driving performance.

[0036] In this embodiment, lower extension frames 6 are provided on both sides of the bottom surface of the second-layer frame 5, and the bottom surface of the lower extension frames 6 rolls in contact with the plurality of rollers 4. With this arrangement, the middle part of the second-layer frame 5 is suspended, which can optimize the utilization of lateral space. For example, the second-layer drive 11 is set on the bottom side of the second-layer frame 5, with one end hinged to the inner side of the bottom support panel 13 and the other end hinged to the bottom side of the second-layer frame 5.

[0037] In this embodiment, the outer side of the roller 4 is provided with at least one limiting annular groove, and the inclined track 2 is provided with a guide strip corresponding to the limiting annular groove. This arrangement prevents the roller 4 from slipping laterally during rolling, and the limiting annular groove always rolls on the guide strip.

[0038] In this embodiment, the inclined track 2 comprises, from top to bottom, a rail bearing surface, a support member, and a base, wherein the base is configured as a height-adjustable structure. The support member can be hollow, and the base can be height-adjustable. Specifically, the base can be a double-layer structure, connected by multiple height-adjusting bolts to adjust the support height of the base, facilitating fine-tuning so that the rail bearing surface is at the same support height.

[0039] In this embodiment, the plurality of ramp tracks 2 on each side are equally spaced along the length direction parallel to the zinc plating tank 7. To increase the backward slip stability of the rollers 4, the plurality of ramp tracks 2 on each side are equally spaced along the length direction parallel to the zinc plating tank 7.

[0040] In this embodiment, the rotating bearing mechanism includes two sets of support rollers symmetrically arranged on both sides of the lifting platform 12. Each set of support rollers is used to support one end of the zinc plating tank 7, and at least one roller shaft 10 in each set of support rollers is capable of rotation. The rotation of the roller shaft 10 drives the supported zinc plating tank 7 to rotate. All four roller shafts 10 in each set of support rollers can rotate in the same direction, or two roller shafts 10 on the same side can rotate in the same direction.

[0041] In this embodiment, to further provide an installation method for the roller shaft 10, the roller shaft 10 is mounted on the fixed support frame 14 via a bearing seat 8, and the roller shaft 10, which serves as the drive, is connected to a drive motor. Alternatively, multiple roller shafts 10 can be driven synchronously as a whole through shaft linkage. Multiple active bevel gears are sleeved on the linkage shaft, and a passive bevel gear meshing with the active bevel gear is installed on each drive roller shaft 10. The drive motor is connected to the linkage shaft, and only the rotation of the linkage shaft is needed to synchronously drive the rotation of multiple drive roller shafts 10.

However, the present invention is not limited to the specific details of the above embodiments.
