Description

Technical field:

[0001] The utility model relates to the technical field of casting turnover devices, and more specifically to a turnover device for shell castings used for precision casting. Background technology:

[0002] Precision casting is a general term for the process of obtaining castings with precise dimensions. Compared with the traditional sand casting process, the castings obtained by precision casting are more precise in size and have better surface finish. Precision casting is also called lost wax casting. Its products are precise, complex, close to the final shape of the parts, and can be used directly without or with little processing. It is an advanced process for near-net-shape forming. At present, the mold used for precision casting is a sand mold. For some smaller castings, a plurality of mold grooves for pouring castings are provided in the sand mold, so that multiple castings can be poured at the same time. After pouring, the casting needs to be transferred to the crushing station to crush the shell and divide the casting at the same time. The current transportation of castings is to hang them on a turnover car with multiple rows of hanging rods. Because the castings hung on the turnover car are long and short, the hanging rods are generally only set on the top of the turnover car. If they are set in the middle of the turnover car at the same time, it will cause interference to the longer castings. When hanging shorter castings, if the hanging rod is set in the middle of the turnover car, more castings can be hung. Therefore, a turnover car with a hanging rod in the middle of the frame but the hanging rod can be stored and hidden is needed. Utility model content:

Specific implementation method:

[0020] Example: See Figures 1 to 4 As shown, a turnover device for precision casting with shell castings includes a turnover frame 1, the turnover frame 1 includes two vertical beams 11, a horizontal bottom beam 12 is fixedly connected between the lower parts of the vertical beams 11, and upper and lower groups of horizontal support beams 13 are fixedly connected between the upper parts, and the bottom ends of the vertical beams 11 are fixedly connected to longitudinal support plates 14, and the front and rear ends of the support plates 14 are respectively provided with wheels 15, and a plurality of groups of horizontally distributed connecting frames 2 are inserted between the supporting beams 13 at the upper parts of the vertical beams 11; a vertical handle 3 is provided on one side of the turnover frame 1, and the upper and lower ends of the handle 3 are respectively formed with horizontal and horizontal guide shafts 31, and the guide shafts 31 are plugged and fixed on the vertical beams 11 of the turnover frame 1 and are respectively inserted in the upper and lower parts of the connecting frame 2;

[0021] The connecting frame 2 includes a vertical first connecting plate 21, and vertical second connecting plates 22 are provided on both sides of the first connecting plate 21. The upper and lower ends of the second connecting plate 22 and the first connecting plate 21 are respectively fixed to the support beam 13, and two groups of suspension frames 4 are respectively inserted between the second connecting plate 22 and the first connecting plate 21. The two groups of suspension frames 4 are respectively located at the upper and lower parts of the connecting frame 2 and close to the support beam 13.

[0022] The hanging frame 4 comprises a transverse regular quadrangular prism 41, which is inserted into the guide shaft 31, and a T-shaped hanging rod 42 is fixedly connected to the outer wall of one end of the regular quadrangular prism 41; square limiting holes 221 are respectively formed on the two side walls of the second connecting plate 22, and the other end of the regular quadrangular prism 41 is inserted into the limiting hole 221 of the second connecting plate 22; Figure 1 As shown, the suspension rods 42 on the upper part of the connecting frame 2 are staggered to the left and right and extend out of the turnover frame 1 respectively and are arranged horizontally, and the suspension rods 42 on the lower part of the connecting frame 2 are arranged vertically and hidden inside the connecting frame 2.

[0023] There is a gap between one end of the hanging rod 42 on the regular quadrangular prism 41 and the first connecting plate 21, and the distance between the regular quadrangular prism 41 and the first connecting plate 21 is not less than the length of the regular quadrangular prism 41 inserted in the second connecting plate 22. The above-mentioned size setting is to achieve that the regular quadrangular prism 41 can be moved out of the second connecting plate 22, so that the regular quadrangular prism 41 can be rotated and positioned.

[0024] The length of the suspension rod 42 is less than half of the length of the first connecting plate 21 , and the length of the first connecting plate 21 is equal to the length of the second connecting plate 22 , so that the two groups of suspension frames 4 on the connecting frame 2 can be rotated and hidden in the connecting frame 2 .

[0025] A first magnetic ring 5 and a second magnetic ring 6 are respectively inserted between the first connecting plate 21 and the second connecting plate 22 of the connecting frame 2. The first magnetic ring 5 and the second magnetic ring 6 are respectively inserted into the guide shaft 31 and repel each other. The first magnetic ring 5 is fixed on the end face of the regular quadrangular prism 41 close to the first connecting plate 21. The first magnetic ring 5 is embedded and fixed on the first connecting plate 21. Based on the magnetic limit, the regular quadrangular prism 41 on the suspension rod 42 can be limited from being separated from the second connecting plate 22.

[0026] A triangular reinforcing rib 43 is fixedly connected to the outer wall of the hanging rod 42 on the side close to the regular quadrangular prism 41. The reinforcing rib 43 is fixedly connected to the regular quadrangular prism 41. When a casting is hung on the hanging rod 42, the stress generated is concentrated at the connection between the hanging rod 42 and the regular quadrangular prism 41. Therefore, the reinforcing rib 43 is used to reinforce the connection between the hanging rod 42 and the regular quadrangular prism 41.

[0027] The length of the suspension rod 42 is smaller than the vertical distance from the bottom end of the vertical beam 11 to the adjacent support beam 13, so as to prevent the casting suspended on the lower suspension frame 4 of the connecting frame 2 from contacting the ground.

[0028] The regular quadrangular prism 41, the first connecting plate 21 and the second connecting plate 22 are respectively formed with guide holes opposite to the guide shaft 31, and the aperture of the guide hole is equal to the diameter of the guide shaft 31. The guide shaft 31 can play a guiding role as well as a supporting role.

[0029] Working principle: The utility model is a turnover device for precision casting with shell castings, and the turnover device is provided with upper and lower two-layer suspension frames 4. The suspension rod 42 on the suspension frame 4 can hang the casting when it is in a horizontal state; and the suspension frame 4 can rotate after being disengaged from the limiting plug hole 221 of the connecting frame 2 by lateral movement, and then inserted into the limiting plug hole 221 of the connecting frame 2 for positioning after rotation; therefore, there are two positioning states of horizontal setting and vertical setting. When it is set vertically, it is hidden in the connecting frame 2 and will not interfere with the suspended casting;

[0030] There are several ways to set up this circulation device:

[0031] 1. The hanging rods 42 on the hanging frame 4 are all arranged vertically, and then the hanging rods 42 are all hidden in the connecting frame 2, and the state of the turnover device is not in use, which can prevent workers from hanging and touching the hanging rods 42;

[0032] 2. The upper hanging rod 42 of the turnover frame 1 is arranged horizontally, and the lower hanging rod 42 is arranged vertically, which can be used to hang castings with a long length;

[0033] 3. The suspension rods 42 of the upper and lower layers of the turnover frame 1 are both arranged horizontally, so that castings with shorter lengths can be suspended on the suspension rods 42 of the upper and lower layers.

[0034] The embodiments are used to illustrate the present invention, but not to limit the present invention. Any person skilled in the art may modify the embodiments without violating the spirit and scope of the present invention, and therefore the scope of protection of the present invention shall be as set forth in the claims of the present invention.
