A rod falling buffer device

Abstract

This utility model discloses a bar falling buffer device, which relates to the field of bar production technology. It includes a support frame with inclined plates evenly arranged on it. From low to high, the inclined plates are respectively equipped with a blocking buffer device, a second buffer component, and a first buffer component. The tops of both the first and second buffer components extend above the inclined plates. When the bar falls, it is first buffered by the first buffer component, and then rolls onto the second buffer component for further buffering, significantly reducing the impact force when it hits the inclined plates. This better buffers the impact force of the falling bar, preventing deformation. A short-stroke secondary spring assists the main spring component in quickly returning from a compressed state to an extended state, effectively buffering the next bar about to fall.

Description

Technical Field

[0001] This utility model relates to the field of bar production technology, specifically to a bar falling buffer device. Background Technology

[0002] The production process of bar stock requires cutting, especially for steel bars. After cutting, the bars are transported by a conveyor chain and multiple cut steel bars fall one after another to the binding point for binding.

[0003] Patent document CN201520891301.8, entitled "A Straightening and Cutting Mechanism for Building Rebar with Magnetic Guidance," addresses the problem that when rebar falls directly at an angle, it can easily deform if the drop is too high, affecting product quality and posing safety hazards. This technical solution addresses this by using an inclined plate on the worktable to facilitate the rolling of the cut rebar. The rolling motion of the rebar after falling provides initial cushioning. When the rebar touches a telescopic baffle, the baffle tilts, causing the rebar to fall. The baffle then resets under the action of a return spring, achieving further cushioning of the falling material. This prevents rebar deformation, maintains product quality, and reduces the risk of accidents.

[0004] However, since inclined plates are generally made of steel, the falling steel bars will still generate a large impact with the inclined plate, so the buffering effect of this technical solution is not good and cannot effectively prevent quality problems from occurring after the steel bars fall. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rod falling buffer device, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a bar falling buffer device, including a support, on which inclined plates are evenly arranged; The inclined plate is equipped with a blocking and buffering device, a second buffering component, and a first buffering component from low to high, and the tops of the first buffering component and the second buffering component both extend above the inclined plate.

[0007] Preferably, the buffer assembly includes a base plate and a top plate. The base plate is disposed on the inclined plate. A main spring is disposed between the base plate and the top plate. A rubber pad is also disposed on the top of the top plate. A secondary spring is disposed around the bottom of the top plate and connected to the base plate. The stroke of the secondary spring is less than that of the main spring.

[0008] Preferably, the second buffer assembly includes a mounting plate disposed on the inclined plate, and a second rubber pad is disposed on the top of the mounting plate.

[0009] Preferably, the tops of the first rubber pad and the second rubber pad are uniformly provided with raised strips.

[0010] Preferably, guide rods are provided on opposite sides of the bottom plate and the top plate. The top and bottom sides of the main spring member are slidably connected to the guide rods on both sides, and the main spring member is provided with a bolt 1 connected to the guide rod. Guide blocks are provided around the bottom of the top plate. The guide blocks are slidably connected to the top of the secondary spring member, and the secondary spring member is provided with a bolt 2 connected to the guide block. Guide posts are provided around the top of the bottom plate and slidably connected to the secondary spring member, and the secondary spring member is provided with a bolt 3 connected to the guide post.

[0011] Preferably, both the base plate and the mounting plate are L-shaped, and reinforcing blocks are provided at the bends of both the base plate and the mounting plate.

[0012] This invention provides a rod falling buffer device. Compared with the prior art, it has the following advantages: 1. The bar falling buffer device first buffers the bar when it falls, and then rolls onto the second buffer for further buffering. This greatly reduces the impact force when the bar falls onto the inclined plate, thus better buffering the impact force of the falling bar and preventing the bar from deforming.

[0013] 2. The bar falling buffer device has a main spring and a secondary spring on the buffer assembly, which can fully buffer the impact force of the bar falling. The short-stroke secondary spring can assist the main spring in quickly returning from the compressed state to the extended state, thus effectively buffering the next bar about to fall.

Detailed Implementation

[0016] 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.

[0017] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A bar falling buffer device includes a support 100, on which inclined plates 200 are evenly arranged for guiding and supporting the bar. The inclined plate 200 is equipped with a blocking and buffering device 300, a second buffering component 500, and a first buffering component 400 from low to high. The tops of the first buffering component 400 and the second buffering component 500 extend above the inclined plate 200. The blocking and buffering device 300 blocks the bar that is ultimately supported by the inclined plate 200. It can be implemented by using the buffering device in patent number CN201520891301.8. When the bar falls, it is first buffered by the first buffering component 400, and then rolls onto the second buffering component 500 for further buffering. This greatly reduces the impact force when the bar falls onto the inclined plate 200, thereby better buffering the impact force of the falling bar and preventing the bar from deforming.

[0018] The buffer assembly 400 includes a base plate 401 and a top plate 402. The base plate 401 is mounted on the inclined plate 200. A main spring 403 is disposed between the base plate 401 and the top plate 402. A rubber pad 404, with the same inclination direction as the inclined plate 200, is also disposed on the top of the top plate 402. Secondary springs 405, connected to the base plate 401, are disposed around the bottom perimeter of the top plate 402. The stroke of the secondary springs 405 is less than the stroke of the main springs 403. The rod falls onto the rubber pad 404. The impact force is buffered by the main spring 403 and the auxiliary spring 405. This effectively buffers the impact force of the falling bar. The short-stroke auxiliary spring 405 has a greater degree of compression, which allows it to reset faster. This helps the main spring 403 to quickly reset from the compressed state to the extended state, thus effectively buffering the next bar that is about to fall. The long stroke of the main spring 403 ensures that it can buffer the larger diameter bars with greater impact force.

[0019] The second buffer assembly 500 includes a mounting plate 501 disposed on the inclined plate 200, and a second rubber pad 502 is disposed on the top of the mounting plate 501. The rods that roll off the first rubber pad 404 fall onto the second rubber pad 502 for further cushioning.

[0020] The tops of rubber pad 1 (404) and rubber pad 2 (502) are uniformly provided with raised strips (406), which can slow down the rolling speed of the rod and help reduce the impact force.

[0021] Guide rods 407 are provided on opposite sides of the base plate 401 and the top plate 402. The top and bottom sides of the main spring component 403 are slidably connected to the guide rods 407 on both sides, and the main spring component 403 is provided with bolts 408 connected to the guide rods 407 for fixation. The guide rods 407 facilitate the positioning and disassembly of the main spring component 403. Guide blocks 409 are provided around the bottom of the top plate 402. The guide blocks 409 are slidably connected to the top of the secondary spring component 405, and the secondary spring component 405 is provided with bolts 4010 connected to the guide blocks 409. The top of the base plate 401 is provided around the top to slidably connect to the secondary spring component 405. The guide post 4011 and the secondary spring component 405 are provided with a bolt 4012 connected to the guide post 4011. The secondary spring component 405 is fixed by bolts 4010 and 4012. The secondary spring component 405 is positioned and disassembled by the guide block 409 and the guide post 4011. It is convenient to replace the damaged main spring component 403 and the secondary spring component 405. The ends of the guide rod 407, the guide block 409 and the guide post 4011 are all provided with blocking structures, which can further position the main spring component 403 and the secondary spring component 405, so that the guide rod 407, the guide block 409 and the guide post 4011 are aligned with the screw holes on the main spring component 403 and the secondary spring component 405.

[0022] The second embodiment differs from the first embodiment in that both the base plate 401 and the mounting plate 501 are L-shaped, and reinforcing blocks are provided at the bends of both the base plate 401 and the mounting plate 501 to improve structural strength.

[0023] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0024] In use, the cut bars roll down one by one, landing on rubber pad 404 for cushioning. At the same time, the main spring 403 and the auxiliary spring 405 provide additional cushioning. Then, they roll onto rubber pad 502 for further cushioning. In this way, the impact force when the bars fall onto the inclined plate 200 is greatly reduced. Finally, the bars roll through the inclined plate 200 to the blocking and buffering device 300 for further cushioning and collection. After collecting a number of bars, they can be bundled together by a bundling machine.
