Description

Technical Field

[0001] This utility model relates to the technical field of casting storage equipment, and more specifically to a flexible buffer device for preventing offset between layers of stacked castings. Background Technology

[0002] After the castings have cooled in the workshop, they generally need to be supported and placed on a support frame. When transferring the castings to the next process, the support frame is directly transported.

[0003] According to the publication (announcement) number: CN218175038U, the publication (announcement) date: 2022-12-30, a support for heat treatment of castings is disclosed, including a tray for supporting castings, a base for mounting multiple trays and transferring them, and a buffer plate and spring located inside the tray for cushioning the castings.

[0004] In the prior art, including the aforementioned patent, when placing some small-sized and thick castings, a bracket with a single vertical column is generally used, and the holes of the castings are aligned with the columns. However, the area of ​​the holes on the castings is usually larger than the area of ​​the columns, so there is a certain amount of sliding between the stacked castings. In order to facilitate handling and transportation, such brackets usually cannot meet the requirements of assembling wheels, so there will inevitably be a certain degree of skew during the handling process. This will eventually act on the stacked castings and cause the castings to shift, reducing the overall stability of the stacked castings on the bracket. At the same time, it will also cause unnecessary friction and collision problems, affecting the surface regularity of the castings. Utility Model Content

[0005] The purpose of this invention is to provide a flexible buffer device to prevent offset between stacked layers of castings, aiming to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flexible buffer device for preventing displacement between stacked castings includes a base with a column, on which multiple castings are stacked, and a collar that slides on the column and is located between adjacent castings, with symmetrically arranged pads fixedly installed on the collar.

[0008] Inflatable bladders that abut against the surface of the casting are fixedly installed on both ends of the pad.

[0009] Preferably, pressure rings are slidably provided on both ends of the collar, with adjacent pressure ring ports engaging in abutment.

[0010] Preferably, a toothed ring is fixedly installed at the pressure ring port.

[0011] Preferably, the collar has symmetrically arranged air cavities, and the air cavities have air ports for communicating with the bladder.

[0012] Preferably, a plug ring that slides in the air cavity is fixedly installed on the pressure ring.

[0013] Preferably, an elastic element is fixedly installed between the plug ring and the air cavity.

[0014] Preferably, the outer ring of the plug ring is fixedly fitted with a rubber ring.

[0015] Preferably, the elastic element is a spring.

[0016] Preferably, the capsule is a rubber capsule.

[0017] Preferably, the toothed ring is an alloy metal ring.

[0018] In the above technical solution, the flexible buffer device for preventing offset between stacked castings provided by this utility model has the following beneficial effects: By applying pressure to the upper and lower end faces of the pad by the casting, the bladder is made thinner and has a larger friction area. When offset occurs during the transfer of the casting, the bladder maintains the current deformation thickness while the whole body exhibits a skewed torque. The torque is offset by the bladder itself needing to reset. This achieves an anti-offset function under the combined action of friction and deformation reset capability. Correspondingly, the heavier the casting, the greater the friction, the greater the inertia during offset, and the greater the offsetting force. The casting is more stable during stacked transfer, the anti-offset effect is better, and the safety and surface regularity of the casting are ensured during transportation.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, a flexible buffer device for preventing displacement between stacked castings includes a base 1 with a column 11, and multiple castings 2 are stacked on the base 1. It also includes a collar 3 that slides on the column 11 and is located between adjacent castings 2. Symmetrically arranged pads 31 are fixedly installed on the collar 3.

[0029] Inflatable bladders 5 are fixedly installed on both ends of the pad 31, which abut against the surface of the casting 2.

[0030] Specifically, when the casting 2 is placed on the outside of the column 11, it must be stacked vertically and neatly in order to reduce the offset between the castings 2 in advance. The arm length of the two pads 31 is greater than the shortest width of various castings 2 (as long as the column 11 on the base 1 is used, the size of the casting 2 will meet this setting) so that the casting 2 is given a stable anti-offset treatment.

[0031] By alternately placing the collar 3 and the casting 2 on the outside of the column 11, the casting 2 applies pressure to the bladder 5 on the upper and lower end faces of the pad 31, making the bladder 5 thinner and having a larger friction area (e.g., Figure 5 (See left side of the diagram). While casting 2 experiences displacement during transport, the capsule 5 maintains its current deformation thickness, but exhibits overall skewed torsional force (e.g., ...). Figure 5 (See right side of the diagram), and utilize the cyst body 5 itself to reposition itself (restore to a vertically flattened state, and...) Figure 5 (See the diagram on the left) to counteract the torque, resulting in an anti-deviation function under the combined action of friction and deformation recovery. Correspondingly, the heavier the casting 2, the greater the friction, the greater the inertia during the deviation action, and the greater the counteracting force. The casting 2 is more stable when stacked and transported, with a better anti-deviation effect, ensuring the safety and surface regularity of the casting 2 during transportation.

[0032] As a further embodiment provided by this utility model, pressure rings 4 are slidably provided on both ends of the collar 3, and the ports of adjacent pressure rings 4 abut against each other.

[0033] Specifically, the length of the pressure ring 4 extending out of the collar 3 is greater than half the thickness of the casting 2.

[0034] By alternately placing the collar 3 and the casting 2, the vertically stacked collar 3 makes the pressure ring 4 abut against each other, and the friction provided by the pressure ring 4 during the contact process further improves the anti-displacement effect.

[0035] As another embodiment further provided in this utility model, a toothed ring 43 is fixedly installed at the port of the pressure ring 4.

[0036] When the upper and lower pressure rings 4 are squeezed together, the toothed rings 43 interlock and mesh (and every other ring 3 will make the pad 31 be on the same vertical line), so that multiple rings 3 are connected into one, and the offset force on the individual casting 2 is synchronously transmitted to the multi-layer pad 31, and the ability to counteract torque is amplified, thus improving the anti-offset capability.

[0037] As another embodiment further provided by this utility model, the collar 3 has symmetrically arranged air cavities 32, and the air cavities 32 have air ports 33 for communicating with the bladder body 5.

[0038] Specifically, the sum of the thickness of the pad 31 and the bladder 5 on it is less than the thickness of the collar 3, so that the collar 3 has more connection area on the column 11, ensuring the working stability of the pad 31 and the bladder 5, while also allowing the air chamber 32 to have more airflow.

[0039] Furthermore, the dimensions.

[0040] The air inside the air chamber 32 is sent into the bladder 5 through the air port 33 to increase the filling degree of the bladder 5 and further increase the deformation flattening degree when pressure is applied by the casting 2, thereby improving the anti-displacement ability. At the same time, the combination of the entire collar 3 and pressure ring 4 is also convenient for carrying and placing.

[0041] As another embodiment provided in this utility model, a plug ring 41 that slides in the air cavity 32 is fixedly installed on the pressure ring 4.

[0042] Specifically, the plug ring 41 is located on the port opposite to the pressure ring 4 and the toothed ring 43.

[0043] The air is compressed by the moving lower stopper ring 41 into the air chamber 32, thereby transferring and utilizing the air and evenly delivering the air into multiple bladders 5.

[0044] As another embodiment of this utility model, an elastic element 42 is fixedly installed between the plug ring 41 and the air cavity 32.

[0045] Specifically,

[0046] The elastic element 42 enables the pressure ring 4 under pressure to transfer force and perform energy storage, and also provides an auxiliary ejection function for the casting 2.

[0047] As another embodiment of this utility model, the outer ring of the plug ring 41 is fixedly fitted with a rubber ring.

[0048] The rubber ring provides a seal during compressed air delivery, ensuring normal airflow and also providing damping for the boost function.

[0049] As another embodiment further provided in this utility model, the elastic element 42 is specifically a spring.

[0050] The spring makes the movement of the pressure ring 4 more pronounced, the power more stable, and the operating cost lower.

[0051] As another embodiment further provided in this utility model, the capsule 5 is specifically a rubber capsule.

[0052] The rubber material makes the capsule 5 more deformable and gives it better ability to recover from deformation.

[0053] As another embodiment further provided in this utility model, the toothed ring 43 is specifically an alloy metal ring.

[0054] The use of alloy metal materials makes the toothed ring 43 more wear-resistant, pressure-resistant, and impact-resistant, ensuring normal meshing of the teeth.

[0055] Working principle: By alternately placing the collar 3 and the casting 2 on the outside of the column 11, the casting 2 applies pressure to the bladder 5 on the upper and lower end faces of the pad 31, making the bladder 5 thinner and with a larger friction area. When the casting 2 is deviated during transportation, the bladder 5 maintains its current deformation thickness while exhibiting an overall skew torque. The torque is offset by the bladder 5's own need to reset, thus achieving an anti-deviation function under the combined action of friction and deformation reset capability. Furthermore, the interlocking toothed rings 43 connect multiple collars 3 into one unit, and the deviation force on a single casting 2 is synchronously transmitted to the multi-layer pad 31, amplifying the torque offset capability and improving the anti-deviation capability.

[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
