A shot blasting strengthening device

Abstract

This invention provides a shot blasting strengthening device. The high-speed shot impacts the casting, causing it to shake. The shaking casting then hits the buffer plate. The rubber layer not only prevents the casting from being scratched by the impact, but also protects the outer surface of the buffer plate and offsets part of the shot impact. Simultaneously, after being impacted, the buffer plate is compressed by the buffer rod, causing the spring to shrink within the buffer groove. The spring's restoring force offsets another part of the shot impact, preventing the casting or buffer plate from directly hitting the inner wall of the shot blasting chamber and causing damage, thus increasing the service life of the shot blasting chamber. After the casting surface is strengthened, workers wearing cut-resistant gloves can move and screen the shot located on the top surface of the filter plate. Alternatively, a vibrator can be used to vibrate the filter plate, allowing the broken shot and impurities that have fallen off the casting surface to fall into the collection box through the filter plate and guide plate. This avoids the problem of easily scratching the surface of the parts when the broken shot and impurities are collected and thrown out again.

Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, and in particular relates to a shot blasting strengthening device. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot ejected by a shot blaster to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, cores, and clean castings. They can also be used to remove burrs, diaphragms, and rust. Shot blasting machines can also remove surface contaminants from partially coated surfaces and provide a surface profile that increases coating adhesion, thereby strengthening the workpiece.

[0003] Existing shot blasting machines, when strengthening the surface of suspended castings, suspend the casting inside the machine housing, and then the shot blaster throws high-speed shot to strengthen the casting surface. However, when strengthening the surface of small castings, the impact of the high-speed shot on the small casting causes strong shaking, which can cause scratches on the machine housing and scratches on the casting surface. Existing shot blasting machines lack a structure for filtering and removing shot fragments and impurities, which means that when the collected shot fragments are thrown out again, they can easily scratch the surface of the parts, resulting in defective parts. Furthermore, impurities mixed in with the shot and ejected at high speed can also damage the casting. Therefore, this utility model proposes a shot blasting strengthening device to solve the above-mentioned problems. Utility Model Content

[0004] This invention provides a shot blasting strengthening device, which aims to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a shot blasting strengthening device, including a shot blasting chamber;

[0006] An impact plate is fixedly installed on the inner wall of the shot blasting chamber. A suspension mechanism is provided on the impact plate. The suspension mechanism includes a buffer block. The buffer block is fixedly installed on the impact plate. A buffer groove is opened on the buffer block. A spring is provided inside the buffer groove. One end of the spring is connected to the bottom wall of the buffer groove, and the other end is connected to a buffer rod. The end face of the buffer rod is fixedly connected to the buffer plate. A hook is fixedly provided on the outer wall of the buffer plate.

[0007] The inner wall of the shot blasting chamber near the bottom is equipped with a detachable filter plate, the filter plate having a pore size smaller than the diameter of the shot blasting.

[0008] Preferably, the bottom surface of the shot blasting chamber is provided with a collection box, which is connected to the internal space of the shot blasting chamber.

[0009] Preferably, a guide plate is provided between the filter plate and the collection box.

[0010] Preferably, there are multiple suspension mechanisms, and the multiple suspension mechanisms are arranged in a matrix.

[0011] Preferably, a rubber pad is provided on the outer surface of the buffer plate.

[0012] Preferably, the top surface of the inner wall of the shot blasting chamber is provided with a shot blaster.

[0013] Preferably, the top surface of the shot blasting chamber is provided with a shot blasting box, and the shot blasting box is connected to the shot blaster.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. During shot blasting, the high-speed shot will impact the casting. Under the impact, the casting will shake and hit the buffer plate. Since the outer side of the buffer plate is equipped with a rubber layer, the rubber layer can not only prevent the casting from hitting the buffer plate and avoid scratching the casting, but also protect the outer side of the buffer plate and offset part of the impact force of the shot blasting. At the same time, after the buffer plate is impacted, the buffer plate will compress the spring in the buffer groove under the action of the buffer rod. At this time, the restoring force of the spring can offset another part of the impact force of the shot blasting, and also prevent the casting or the buffer plate from directly hitting the inner wall of the shot blasting chamber and causing damage to the inner wall, thus increasing the service life of the shot blasting chamber. After the shot blasting is completed, the other side of the casting can be strengthened, and then the casting with the strengthened surface can be taken out.

[0016] 2. After the surface strengthening of the casting is completed, the worker puts on anti-cut gloves and moves the shot on the top surface of the filter plate to remove the blasting particles. Alternatively, a vibrator can be used to vibrate the filter plate so that the broken shot and impurities that fall off the surface of the casting fall into the collection box through the filter plate and guide plate. Then the remaining shot is recycled into the shot blasting box. This avoids the problem of easily scratching the surface of the parts when the broken shot and impurities are collected and thrown out again. Attached Figure Description

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a shot blasting strengthening device, including a shot blasting chamber 1; an anti-impact plate 2 is fixedly installed on the inner wall of the shot blasting chamber 1, and a suspension mechanism 3 is provided on the anti-impact plate 2. The suspension mechanism 3 includes a buffer block 4, which is fixedly installed on the anti-impact plate 2. A buffer groove 5 is opened on the buffer block 4, and a spring 6 is provided inside the buffer groove 5. One end of the spring 6 is connected to the bottom wall of the buffer groove 5, and the other end is connected to a buffer rod 7. A buffer plate 8 is fixedly connected to the end face of the buffer rod 7, and a hook 9 is fixedly provided on the outer wall of the buffer plate 8; a detachable filter plate 10 is provided on the inner wall of the shot blasting chamber 1 near the bottom, and the filter hole diameter of the filter plate 10 is smaller than the diameter of the shot blasting.

[0029] For further details, please refer to Figure 3 There are multiple suspension mechanisms 3, which are arranged in a matrix.

[0030] Furthermore, a rubber pad is provided on the outer surface of the buffer plate 8.

[0031] For further details, please refer to Figure 3 The shot blasting chamber 1 is equipped with a shot blaster 13 on the top surface of its inner wall.

[0032] For further details, please refer to Figure 1 The top surface of the shot blasting chamber 1 is provided with a shot blasting box 14, which is connected to the shot blaster 13.

[0033] In this embodiment, when it is necessary to strengthen the surface of a suspended casting, the casting is hung on hook 9. Multiple castings can be hung at once. Then, the door of the shot blasting chamber 1 is closed, and sufficient shot is added to the shot blasting box 14. Then, the shot blaster 13 is started, and a large number of shot are thrown out to hit the surface of the suspended casting, strengthening the surface of the casting (sand removal, core removal, and cleaning, etc.). During the shot blasting process, the high-speed shot will give the casting an impact force. Under the action of the impact force, the casting will shake. The shaking of the casting will hit the buffer plate 8. Due to the outer surface of the buffer plate 8... The side is provided with a rubber layer, which not only prevents the casting from hitting the buffer plate 8 and avoiding scratches on the casting, but also protects the outer side of the buffer plate 8 and can offset part of the impact force of shot blasting. At the same time, after the buffer plate 8 is impacted, it will squeeze the spring 6 into the buffer groove 5 under the action of the buffer rod 7. At this time, the restoring force of the spring 6 can offset another part of the impact force of shot blasting, and also prevent the casting or the buffer plate 8 from directly hitting the inner wall of the shot blasting chamber 1 and causing damage to the inner wall, thus increasing the service life of the shot blasting chamber 1. After the shot blasting is completed, the other side of the casting can be strengthened, and then the casting with the strengthened surface can be taken out.

[0034] After the surface strengthening of the casting is completed, the worker puts on cut-resistant gloves and moves the shot on the top surface of the filter plate 10 to remove impurities. Alternatively, a vibrator can be used to vibrate the filter plate 10, so that the broken shot and impurities falling off the surface of the casting fall into the collection box 12 through the filter plate 10 and the guide plate 11. Then the remaining shot is recycled into the shot blasting box 14. This avoids the problem of easily scratching the surface of the parts when the broken shot and impurities are collected and thrown out again. Then the broken shot and impurities in the collection box 12 are recycled.

[0035] For further details, please refer to Figure 3 The bottom surface of the shot blasting chamber 1 is provided with a collection box 12, which is connected to the internal space of the shot blasting chamber 1.

[0036] For further details, please refer to Figure 3 A guide plate 11 is provided between the filter plate 10 and the collection box 12.

[0037] In this embodiment, after the surface strengthening of the casting is completed, the worker wears cut-resistant gloves and moves the shot blasting material on the top surface of the filter plate 10 to remove it. Alternatively, a vibrator can be used to vibrate the filter plate 10, so that the broken shot and impurities falling off the surface of the casting fall into the collection box 12 through the filter plate 10 and the guide plate 11. Then, the remaining shot blasting material is recycled into the shot blasting box 14. This avoids the problem that the broken shot and impurities are easily scratched on the surface of the parts when they are collected and thrown out again.

[0038] For further details, please refer to Figure 3 The shot blasting chamber 1 is equipped with a shot blaster 13 on the top surface of its inner wall.

[0039] In this embodiment, the shot blasting machine 13 is provided in multiple sets. The multiple sets of shot blasting machines 13 can cooperate to blast shot in any direction in the shot blasting chamber 1, so that more castings can be surface strengthened at the same time in the shot blasting chamber 1.

[0040] The working principle and usage process of this utility model are as follows: When it is necessary to strengthen the surface of a suspended casting, the casting is hung on hook 9. Multiple castings can be hung at once. Then, the door of the shot blasting chamber 1 is closed, and sufficient shot is added to the shot blasting box 14. Then, the shot blaster 13 is started, and a large number of shot are thrown out to hit the surface of the suspended casting, strengthening the surface of the casting (sand removal, core removal, and cleaning, etc.). During the shot blasting process, the high-speed shot will give the casting an impact force. Under the action of the impact force, the casting will shake. The shaking of the casting will hit the buffer plate 8. Due to the buffer... The outer side of plate 8 is provided with a rubber layer. The rubber layer can not only prevent the casting from hitting the buffer plate 8 and avoid scratching the casting, but also protect the outer side of the buffer plate 8 and offset part of the impact force of shot blasting. At the same time, after the buffer plate 8 is impacted, it will squeeze the spring 6 into the buffer groove 5 under the action of the buffer rod 7. At this time, the restoring force of the spring 6 can offset another part of the impact force of shot blasting, and also prevent the casting or the buffer plate 8 from directly hitting the inner wall of the shot blasting chamber 1 and causing damage to the inner wall, thus increasing the service life of the shot blasting chamber 1. After the shot blasting is completed, the other side of the casting can be strengthened, and then the casting with the strengthened surface can be taken out.

[0041] After the surface strengthening of the casting is completed, the worker puts on cut-resistant gloves and moves the shot on the top surface of the filter plate 10 to remove the blasting particles. Alternatively, a vibrator can be used to vibrate the filter plate 10, so that the broken shot and impurities that fall off the surface of the casting fall into the collection box 12 through the filter plate 10 and the guide plate 11. Then the remaining shot is recycled into the shot blasting box 14. This avoids the problem of easily scratching the surface of the parts when the broken shot and impurities are collected and thrown out again.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
