Description
Technical Field
[0001] This utility model relates to a hanger for die-cast parts of a shot blasting machine, and more particularly to the structure of such a hanger. Background Technology
[0002] After die casting is produced, it needs to be shot blasted. The shot blasting machine uses a high-speed turbine to propel a carrier (steel shot) instantaneously, impacting the surface of the die casting to remove sand, cores, and clean it. Shot blasting not only removes oxide scale and adhering sand from the die casting surface, but also detects surface defects such as subcutaneous porosity, slag inclusions, adhering sand, cold shuts, and peeling. For non-ferrous metal castings, such as aluminum alloy castings, in addition to removing oxide scale and detecting surface defects, it is primarily used to remove burrs from the die casting.
[0003] Vertical shot blasting machines require hangers to suspend die-cast parts within the shot blasting chamber for processing. However, existing hangers have several drawbacks, such as low clamping efficiency and a limited number of die-cast parts that can be clamped at a time (typically less than 10), leading to frequent downtime for part replacement and impacting production capacity. There are also numerous blind spots in the shot blasting process, with die-cast parts obstructing each other or the hangers themselves, resulting in incomplete cleaning of internal cavities or threaded holes. Furthermore, the high damage rate of die-cast parts, due to rigid collisions between the parts and the hangers during shot blasting, easily causes scratches or deformation. The hangers also have a short lifespan; prolonged shot blasting impact causes hook deformation and weld cracking, increasing production costs. Additionally, existing hangers are non-adjustable, limiting their use to single-type and single-size die-cast parts, making them inconvenient to use.
[0004] The purpose of this invention is to solve the problems of low clamping efficiency and incomplete cleaning of die-casting parts in existing shot blasting machines. Summary of the Invention
[0005] To address the aforementioned problems, this utility model provides a die-casting part hanger for a shot blasting machine, comprising a bracket 1 and multiple adjusting rods 2. The bracket 1 is a square frame, with a rotating lifting lug 11 at its top for hanging on the hook 51 of the shot blasting machine 5. The adjusting rods 2 are horizontally positioned inside the bracket 1, with both ends detachably connected to the bracket 1. Multiple hooks 3 are provided on the bottom surface of the adjusting rods 2. The multiple adjusting rods 2 are parallel to each other, maintaining a certain distance.
[0006] This invention features multiple adjusting rods 2 inside a support 1, which can move up and down within the support 1. This allows for adjustment of the spacing between the adjusting rods 2 according to the size of the die-cast parts 52, enabling the clamping of die-cast parts 52 of different sizes for shot blasting. This prevents the die-cast parts 52 from obstructing each other or the hangers from blocking them, thus improving the shot blasting effect. Multiple hooks 3 are provided on the adjusting rods 2, allowing for the simultaneous hanging of multiple die-cast parts 52, further increasing shot blasting efficiency. This invention solves the problems of low clamping efficiency and incomplete cleaning in existing shot blasting machines.
[0007] Preferably, multiple adjustment holes 12 are provided on the left and right sides of the bracket 1, and the multiple adjustment holes 12 are equally spaced in the vertical direction. The adjustment rod 2 is connected to the bracket 1 through a pin 21 passing through the adjustment hole 12.
[0008] By setting multiple adjustment holes 12 on the left and right sides of the bracket 1, the adjustment rod 2 is connected to the bracket 1 through the pin 21 passing through the adjustment hole 12, so that the position of the adjustment rod 2 can be easily adjusted. The spacing between the adjustment rods 2 can be adjusted according to the size of the die-casting part 52 to adapt to the shot blasting treatment of die-casting parts 52 of different sizes.
[0009] Preferably, a groove 22 is provided on the bottom surface of the adjusting rod 2, and a plurality of adjusting sliders 23 are provided in the groove 22. The adjusting sliders 23 are slidably disposed in the groove 22, and a threaded rod 24 is provided at the lower end of the adjusting sliders 23. The threaded rod 24 extends vertically, with its upper end connected to the adjusting slider 23 and its lower end extending below the groove 22. A locking nut 25 is provided on the threaded rod 24, and a hook 3 is provided at the lower end of the threaded rod 24.
[0010] A groove 22 is provided on the bottom surface of the adjusting rod 2, and an adjusting slider 23 is provided within the groove 22. The hook 3 is connected to the adjusting slider 23 via a threaded rod 24. By sliding the adjusting slider 23 within the groove 22, the position of the hook 3 can be adjusted, thereby adjusting the spacing of the hooks 3. This allows for the hanging and shot blasting of die-cast parts 52 of different sizes, preventing the die-cast parts 52 from obstructing each other during shot blasting, which would result in numerous blind spots and affect the shot blasting effect. A locking nut is provided on the threaded rod 24. By rotating the locking nut 25, the nut 25 abuts against the adjusting rod 2, which can fix the adjusting slider 23 and prevent the hook 3 from shaking during shot blasting.
[0011] Preferably, the hook 3 is connected to the lower end of the threaded rod 24 via a universal ball joint 31. By connecting the hook 3 to the lower end of the threaded rod 24 via the universal ball joint 31, the angle of the hook 3 can be rotated as needed to adapt to the shot blasting angle requirements of workpieces with different shapes.
[0012] Preferably, it also includes a counterweight mechanism 4, which includes a slide rail 41, a counterweight slider 42, and a counterweight block 43. The slide rail 41 is fixedly disposed at the bottom of the bracket 1, the counterweight slider 42 is slidably disposed on the slide rail 41, and the counterweight block 43 is fixedly disposed on the counterweight slider 42.
[0013] By setting a counterweight 43 at the bottom of the bracket 1, the position of the center of gravity of the bracket 1 can be adjusted by moving the counterweight 43, ensuring that the hanger remains vertical in the shot blasting chamber, reducing swaying and improving the shot blasting effect.
[0014] Preferably, the bracket 1 is welded from a square steel tube.
[0015] Preferably, a buffer pad is provided on the outer periphery of the hook 3 and the bracket 1. By providing a buffer pad on the outer periphery of the hook 3 and the bracket 1, deformation and weld cracking caused by shot blasting impact can be prevented, thus extending their service life.

[0025] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0026] like Figure 1 and Figure 2 As shown, the die-casting fixture for shot blasting machine includes a bracket 1, a counterweight mechanism 4, and multiple adjusting rods 2. The bracket 1 is a square frame structure, which is welded together from four square steel pipes located on the top, bottom, left, and right sides of the bracket 1.
[0027] The top of the bracket 1 is equipped with a rotating lifting lug 11, which can be used to suspend the bracket from the hook 51 of the shot blasting machine 5.
[0028] The counterweight mechanism 4 includes a slide rail 41, a counterweight slider 42, and a counterweight block 43. The slide rail 41 is fixedly installed at the bottom of the bracket 1, the slider is slidably installed on the slide rail 41, and the counterweight block 43 is fixedly installed on the counterweight slider 42.
[0029] By setting a counterweight 43 at the bottom of the bracket 1, the position of the center of gravity of the bracket 1 can be adjusted by moving the counterweight 43, ensuring that the hanger remains vertical in the shot blasting chamber, reducing swaying and improving the shot blasting effect.
[0030] Multiple adjustment holes 12 are provided on the left steel pipe 13 and the right steel pipe 14 of the bracket 1, and the multiple adjustment holes 12 are equally spaced in the vertical direction.
[0031] The adjusting rod 2 is horizontally installed inside the bracket 1. Both ends of the adjusting rod 2 are connected to the bracket 1 through pins 21 passing through the adjusting hole 12. Multiple hooks 3 are provided on the bottom surface of the adjusting rod 2.
[0032] Therefore, the adjusting rod 2 is connected to the bracket 1 by a pin 21 passing through the adjusting hole 12. Pulling out the pin 21 can move the position of the adjusting rod 2, and inserting the pin 21 can fix the adjusting rod 2 and the bracket 1, thereby facilitating the adjustment of the position of the adjusting rod 2. The spacing between the adjusting rods 2 can be adjusted according to the size of the die-casting part 52 to adapt to the shot blasting treatment of die-casting parts 52 of different sizes.
[0033] In this embodiment, three adjusting rods 2 are provided, which are parallel to each other and maintain a certain distance. In other embodiments, other numbers of adjusting rods 2 can be provided as needed, such as four, five or more.
[0034] like Figure 3 and Figure 4 As shown, a groove 22 is provided on the bottom surface of the adjusting rod 2, and multiple adjusting sliders 23 are provided in the groove 22. The adjusting sliders 23 are slidably disposed in the groove 22, and a threaded rod 24 is provided at the lower end of the adjusting sliders 23.
[0035] The threaded rod 24 extends vertically, with its upper end connected to the adjusting slider 23 and its lower end extending below the slide groove 22. A locking nut 25 is provided on the threaded rod 24. By rotating the locking nut 25, the nut 25 abuts against the adjusting rod 2, which can fix the adjusting slider 23 and prevent the hook 3 from shaking during shot blasting.
[0036] Therefore, by adjusting the slider 23 to slide within the groove 22, the position of the hook 3 can be adjusted, thereby adjusting the spacing of the hook 3. This allows for the hanging and shot blasting of die-cast parts 52 of different sizes, preventing the die-cast parts 52 from blocking each other during shot blasting, which would result in many blind spots and affect the shot blasting effect.
[0037] The hook 3 is connected to the lower end of the threaded rod 24 via a universal ball joint 31. By connecting the hook 3 to the lower end of the threaded rod 24 via the universal ball joint 31, the angle of the hook 3 can be rotated as needed to adapt to the shot blasting angle requirements of workpieces with different shapes.
[0038] The hook 3 has a spring clip 32. By setting the spring clip 32 on the hook 3, the die-cast part 52 can be prevented from falling off during shot blasting.
[0039] A cushioning pad with anti-slip texture is provided on the outer periphery of hook 3 and bracket 1. The cushioning pad is made of polyurethane material. By providing a cushioning pad on the outer periphery of hook 3 and bracket 1, deformation and weld cracking caused by shot blasting impact can be prevented, thus extending their service life.
[0040] like Figure 5 As shown, during use, first, adjust the spacing of each adjusting rod 2 according to the size and structure of the die-cast part 52. To adjust, pull the pin 21 out of the bracket 1 and the adjusting rod 2, then move the adjusting rod 2 to the appropriate position, and then insert the pin 21 from the adjusting hole 12 on the bracket 1 into the adjusting rod 2 to fix it. Next, adjust the spacing between each hook 3 on the adjusting rod 2 according to the size and structure of the die-cast part 52. To adjust, first loosen the locking nut 25 on the threaded rod 24, then move the adjusting slider 23 to move the hook 3 to the appropriate position, and then tighten the locking nut 25 on the threaded rod 24 to fix the hook 3. Finally, suspend the fixture on the hook 51 of the shot blasting machine 5 via the rotating lifting lug 11, and then hang the die-cast part 52 sequentially on each hook 3 to begin shot blasting treatment of the die-cast part 52.
[0041] This invention features multiple adjusting rods 2 inside a support 1, which can move up and down within the support 1. This allows for adjustment of the spacing between the adjusting rods 2 according to the size of the die-cast part 52, accommodating shot blasting of die-cast parts 52 of different sizes. This prevents the die-cast parts 52 from obstructing each other or the hanging fixtures from blocking them, thus improving the shot blasting effect. Multiple hooks 3 are also provided on the adjusting rods 2, allowing for the simultaneous hanging of multiple die-cast parts 52, further enhancing shot blasting efficiency.
[0042] By setting multiple adjustment holes 12 on the left and right sides of the bracket 1, the adjustment rod 2 is connected to the bracket 1 through the pin 21 passing through the adjustment hole 12, so that the position of the adjustment rod 2 can be easily adjusted. The spacing between the adjustment rods 2 can be adjusted according to the size of the die-casting part 52 to adapt to the shot blasting treatment of die-casting parts 52 of different sizes.
[0043] A groove 22 is provided on the bottom surface of the adjusting rod 2, and an adjusting slider 23 is provided within the groove 22. The hook 3 is connected to the adjusting slider 23 via a threaded rod 24. By sliding the adjusting slider 23 within the groove 22, the position of the hook 3 can be adjusted, thereby adjusting the spacing of the hooks 3. This allows for the hanging and shot blasting of die-cast parts 52 of different sizes, preventing the die-cast parts 52 from obstructing each other during shot blasting, resulting in numerous blind spots and affecting the shot blasting effect. A locking nut is provided on the threaded rod 24. By rotating the locking nut 25, the nut 25 abuts against the adjusting rod 2, which can fix the adjusting slider 23 and prevent the hook 3 from shaking during shot blasting. A counterweight 43 is provided at the bottom of the support 1. Moving the counterweight 43 can adjust the position of the center of gravity of the support 1, ensuring that the hanger remains vertical in the shot blasting chamber, reducing shaking and improving the shot blasting effect.
[0044] It should be noted that the above embodiments are illustrative of the present invention and not intended to limit the present invention.
