Description

Technical Field

[0001] This utility model belongs to the technical field of shot blasting hangers for cast iron parts. Specifically, this utility model relates to a shot blasting hanger structure for cast iron parts. Background Technology

[0002] For small-scale production lines producing stop blocks and 063 iron cores, the castings are small in size and have thin ingates, making them prone to scattering during vibration sand removal and roller blasting. Existing tooling cannot handle the scattered castings during shot blasting; instead, the iron cores are simply thrown directly into the shot blasting chamber, leading to quality issues such as over-blasting and under-blasting. Furthermore, removing the cores from the chamber increases equipment downtime. On average, out of 5,000 pieces produced per month, 500 are scattered, requiring 10 processing cycles. Each processing cycle takes an average of 20 minutes, resulting in 20 minutes of equipment downtime and an average monthly processing time of 66 hours, impacting production efficiency.

[0003] Chinese Patent (Publication No.: 222521014U) discloses a small-scale shot blasting fixture structure for castings, including an adjusting block, a lifting block, a moving block, a displacement block, a lead screw, and a driving component. The lead screw rotates to move the moving block and the displacement block within an adjusting groove. The movement of the moving block and the displacement block causes the adjusting block and the lifting block to move within the range of the hook's main rod, thereby adjusting the distance between them. This small-scale shot blasting fixture structure for castings is prone to wear on the iron core, causing damage to the castings. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a shot blasting hanger structure for cast iron parts that is suitable for small-sized cast iron parts with matching shapes and sizes. To achieve the above objective, the technical solution adopted by this utility model is as follows: a shot blasting hanger structure for cast iron parts, including a suspension plate, the suspension plate being connected to a shot blasting machine, and the suspension plate being connected to a suspension assembly.

[0005] The suspension assembly includes a main rod connected to a suspension plate, a first crossbar connected to the main rod, and a first iron core placement rod disposed on the first crossbar.

[0006] One end of the main rod is connected to a second crossbar, and a second iron core placement rod is provided on the second crossbar. A support rod is provided between the first crossbar and the second crossbar.

[0007] A third crossbar is connected to the main rod, and a third iron core placement rod is provided on the third crossbar.

[0008] A fourth iron core placement rod is provided on the support rod.

[0009] The first iron core placement rod, the second iron core placement rod, the third iron core placement rod, and the fourth iron core placement rod are all arc-shaped structures.

[0010] The suspension plate is provided with suspension holes, which are connected to the shot blasting machine.

[0011] The first, second, and third crossbars are arranged symmetrically around the main rod.

[0012] The first iron core placement rod is set at equal intervals on the first horizontal bar, the second iron core placement rod is set at equal intervals on the second horizontal bar, the third iron core placement rod is set at equal intervals on the third horizontal bar, and the fourth iron core placement rod is set at equal intervals on the support rod.

[0013] The technical advantages of this invention are as follows: the first, second, and third crossbars are symmetrically arranged around the main rod, with the third crossbar forming a 30-degree angle with the first crossbar. This layout creates a compact and rational three-dimensional suspension space. Combined with the equally spaced iron core placement rods on the crossbars, this greatly improves space utilization, allowing more iron cores to be processed in a single shot blasting process, thus significantly improving shot blasting efficiency.

[0014] The first, second, third, and fourth iron core placement rods all adopt an arc-shaped structure with an upward tilt of 5-15° at the end, which matches the shape of the iron core and can firmly fix the iron core. The iron core is well fixed, effectively preventing the iron core from falling out of the shot blasting machine. The first, second, and third crossbars and the support rod provide installation support for the first, second, third, and fourth iron core placement rods, further enhancing space utilization.

[0015] The staggered spatial arrangement of the first, second, third, and fourth iron core placement rods avoids the problem of shot blasting obstruction caused by the close proximity of the cast iron parts. This ensures that each iron core is fully exposed within the shot impact range, guaranteeing the uniformity and comprehensiveness of shot blasting, thereby improving the shot blasting quality of the cast iron parts.

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0020] like Figure 1 As shown, a shot blasting hanger structure for cast iron parts includes a suspension plate 1, which is connected to a shot blasting machine. The suspension plate 1 is also connected to a suspension assembly 2. The suspension plate 1 serves as the connection hub between the entire hanger structure and the shot blasting machine, its main function being to achieve a stable connection between the hanger structure and the shot blasting machine. The suspension holes 101 provided on the suspension plate 1 can engage with corresponding chain hooks on the shot blasting machine, accurately and securely installing the hanger structure inside the machine. The suspension assembly 2 engages with the cast iron parts, providing a placement position for the iron core.

[0021] The suspension assembly 2 includes a main rod 201, which is connected to the suspension plate 1. A first crossbar 202 is connected to the main rod 201, and a first iron core placement rod 203 is provided on the first crossbar 202. The main rod 201 is the core support component of the suspension assembly 2. The first crossbar 202 is used to connect the first iron core placement rod 203. By fitting the iron core onto the first iron core placement rod 203, the iron core is firmly fixed during shot blasting, and the iron core is not easy to fall out of the shot blasting machine after placement.

[0022] One end of the main rod 201 is connected to a second crossbar 3, on which a second iron core placement rod 301 is installed. A support rod 302 is installed between the first crossbar 202 and the second crossbar 3. One end of the second crossbar 3 is connected to the main rod 201. The second crossbar 3 mainly provides installation support for the second iron core placement rod 301. By fitting the iron core onto the second iron core placement rod 301, the iron core is firmly fixed during shot blasting, preventing it from falling out of the shot blasting machine. The first crossbar 202 and the second crossbar 3 are arranged parallel to each other. The support rod 302 connects the first crossbar 202 and the second crossbar 3, enhancing the overall strength and stability of the hanger structure. It prevents the first crossbar 202 and the second crossbar 3 from deforming or being damaged due to excessive force. At the same time, the support rod 302 makes the force on the first crossbar 202 and the second crossbar 3 more balanced in all directions.

[0023] A third crossbar 4 is connected to the main rod 201, and a third iron core placement rod 401 is mounted on the third crossbar 4. The third crossbar 4 is connected to the main rod 201 and provides an installation position for the third iron core placement rod 401. The third crossbar 4 is located between the first crossbar 202 and the second crossbar 3. From a top-down view, the third crossbar 4 forms a 30-degree angle with the first crossbar 202, creating a more compact and reasonable three-dimensional suspension space. When the cast iron parts are suspended on the third iron core placement rod 401, they are spatially offset from the cast iron parts suspended on the first iron core placement rod 203 and the second iron core placement rod 301, avoiding the problem of iron core obstruction caused by excessive proximity. This significantly improves the uniformity and comprehensiveness of shot blasting.

[0024] A fourth iron core placement rod 5 is provided on the support rod 302. The iron core can be sleeved on the fourth iron core placement rod 5. The iron core can be sleeved on the first iron core placement rod 203, the second iron core placement rod 301, the third iron core placement rod 401 and the fourth iron core placement rod 5. Multiple iron cores can be processed in one shot blasting process, which improves shot blasting efficiency.

[0025] The first iron core placement rod 203, the second iron core placement rod 301, the third iron core placement rod 401, and the fourth iron core placement rod 5 are all arc-shaped structures. The arc-shaped structure means that the ends of the first iron core placement rod 203, the second iron core placement rod 301, the third iron core placement rod 401, and the fourth iron core placement rod 5 are inclined upward at 5-15°, which makes it easier for the iron core to not fall off in the shot blasting machine after placement.

[0026] The suspension plate 1 is provided with a suspension hole 101, which is connected to the shot blasting machine. The suspension hole 101 is connected to the chain hook of the shot blasting machine, allowing the entire structure to enter the shot blasting chamber of the shot blasting machine via the chain.

[0027] The first crossbar 202, the second crossbar 3, and the third crossbar 4 are arranged symmetrically around the main rod 201. This increases space utilization, allowing more iron cores to be processed in a single shot blasting process.

[0028] The first iron core placement rod 203 is evenly spaced on the first crossbar 202, the second iron core placement rod 301 is evenly spaced on the second crossbar 3, the third iron core placement rod 401 is evenly spaced on the third crossbar 4, and the fourth iron core placement rod 5 is evenly spaced on the support rod 302. This design increases space utilization, allowing more iron cores to be processed in a single shot blasting process.

[0029] The role and effect of the embodiments

[0030] The first crossbar 202, the second crossbar 3, and the third crossbar 4 are arranged symmetrically around the main rod 201, with the third crossbar 4 forming a 30-degree angle with the first crossbar 202. This layout creates a compact and efficient three-dimensional suspension space. Combined with the equally spaced iron core placement rods on the crossbars, this greatly improves space utilization, allowing more iron cores to be processed in a single shot blasting process, significantly enhancing shot blasting efficiency.

[0031] The first iron core placement rod 203, the second iron core placement rod 301, the third iron core placement rod 401, and the fourth iron core placement rod 5 all adopt an arc-shaped structure with an upward tilt of 5-15° at the end, which matches the shape of the iron core and can firmly fix the iron core. The iron core is well fixed, effectively preventing the iron core from falling out of the shot blasting machine. The first crossbar 202, the second crossbar 3, the third crossbar 4, and the support rod 302 provide installation support for the first iron core placement rod 203, the second iron core placement rod 301, the third iron core placement rod 401, and the fourth iron core placement rod 5, further enhancing the space utilization rate.

[0032] The staggered spatial arrangement of the first iron core placement rod 203, the second iron core placement rod 301, the third iron core placement rod 401, and the fourth iron core placement rod 5 avoids the problem of shot blasting obstruction caused by the close proximity of the cast iron parts. This ensures that each iron core is fully exposed within the impact range of the shot, guaranteeing the uniformity and comprehensiveness of shot blasting, thereby improving the shot blasting quality of the cast iron parts.
