Description

Technical Field

[0001] The present invention relates to the technical field of shell reinforcement, and particularly relates to a tool for reinforcing the shell of a frame-type precision casting. Background Art

[0002] Existing shell reinforcement usually uses the method of shell making in sand casting. The shell after coating is placed in an iron frame for rectangular sand mold shaping, and the gap between the shell and the iron frame is filled with silica sand. After the silica sand is solidified, it hugs the shell for fixation. The advantage of this method is that the sand is in close contact with the shell at room temperature and the strength of the sand is very high. However, after baking at a certain temperature, the sand will collapse, directly resulting in a significant reduction in the shell reinforcement force.

[0003] The prior art discloses a cage structure composed of longitudinal keels and transverse beams. However, the mentioned reinforcement is a flexible rope, which requires the flexible rope to be a non-metallic material with high temperature resistance and a small linear / body shrinkage ratio, and there are limitations in material selection. At the same time, the adopted bottom plate is a single solid structure. For non-standard shells of different shapes, the shape of this tool can be adapted, but it cannot achieve that one tool can be used for non-standard shells of multiple shapes, and there is a problem of repeatedly processing the reinforcement body adapted to it. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a tool for reinforcing the shell of a frame-type precision casting. This patent avoids the limitation of sand collapse during baking at a certain temperature, uses metal materials and high-temperature-resistant materials, can be applicable to high-temperature heating, and avoids environmental pollution.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a tool for reinforcing the shell of a frame-type precision casting, including a bottom plate, two parallel main plates, two side plates arranged between the two main plates, and fasteners for reinforcing the precision casting. Both main plates are installed above the bottom plate. One end of the side plate is installed on one of the main plates, and the other end of the side plate is installed on the other main plate. A cavity is jointly formed between the two main plates and the two side plates, and the precision casting is arranged in this cavity.

[0006] Further, a number of mutually parallel installation grooves Ⅰ are provided on the bottom plate. The number of installation grooves Ⅰ is arranged at intervals along the length direction of the bottom plate, and the main plate is installed on the bottom plate through the installation grooves Ⅰ.

[0007] Further, the installation groove Ⅰ is in the shape of a dovetail groove.

[0008] Further, through holes are provided on the bottom plate.

[0009] Further, a number of installation grooves Ⅱ are arranged along the height direction of the inner side of the main plate, and the side plate is installed on the main plate through the installation grooves Ⅱ.

[0010] Further, a plurality of reinforcing grooves I are formed on the main board, and the plurality of reinforcing grooves I are arranged at intervals in the vertical direction.

[0011] Further, a plurality of reinforcing grooves II are formed on the side board, and the plurality of reinforcing grooves II are arranged at intervals in the vertical direction.

[0012] Further, fasteners can be arranged at the positions of the reinforcing grooves I and the reinforcing grooves II.

[0013] Further, the fastener includes a reinforcing block, a connecting rod, an adjusting spring and a locking nut. The reinforcing block and the adjusting spring are both arranged in the cavity.

[0036] Embodiment 1

[0037] Next, various exemplary embodiments, features, and aspects of the present invention will be described in detail with reference to the accompanying drawings.

[0038] First, in combination with Figures 8 to 9 to illustrate the structure of the device for reinforcing the shell of the frame-type casting of the present invention.

[0039] An industrial tool for reinforcing the shell of a frame-type precision casting of the present invention: a bottom plate 1, a main board 2 fixed on the bottom plate 1, a side board 3 connected to the main board 2, and a targeted fastening member 4 for the special-shaped part of the casting. One end of the reinforcement block 9 of the fastening member 4 away from the connecting rod 10 is pasted with asbestos felt. The reinforcement block 9 does not directly contact the casting, but contacts the casting after setting asbestos felt on the surface of the reinforcement block 9. The adjusting spring 11 is sleeved outside the connecting rod 10.

[0040] Next, in combination with the structure of the above industrial tool for reinforcing the shell of a frame-type precision casting, for the convenience of applying to large-scale frame-type castings, the assembly method of the device for reinforcing the shell according to the present invention that can achieve rapid installation will be described. First, the casting is tightly wound with a high-temperature-resistant material, such as asbestos felt, etc., and placed on the bottom plate 1, and the gate position is aligned with the through hole 101 on the bottom plate 1. The main board 2 is inserted into the outermost side of the bottom plate 1 through the dovetail groove structure 5 of the installation groove I 5 on the bottom plate 1. The remaining dovetail groove structures 5 on the bottom plate 1 can be filled with T-shaped blocks that completely match the dovetail groove structure, or can be left unfilled. The side board 3 is connected to the main board 2 through the installation groove II 6 on the main board 2 and is inserted into the installation groove II 6 on the outer side of the main board 2. The cross-section of the installation groove II 6 is a U-shaped groove structure.

[0041] According to the special-shaped parts of the frame-type casting, such as irregular grooves, for the irregular grooves that cannot be completely contacted with the wound asbestos felt, flexible materials are used for complete filling, and then the fastening member 4 is used to tightly press the grooves. According to the specific positions of the grooves or other special-shaped structures, targeted fastening can be carried out through the reinforcement groove I 7 on the main board 2 and the reinforcement groove II 8 on the side board 3.

[0042] And the different positions at approximately the height of the casting or the different positions at different heights are simultaneously fastened through the reinforcing groove I 7 on the main board 2 and the reinforcing groove II 8 on the side board 3.

[0043] The fastener 4 is connected to the main board 2 or the side board 3 through a rectangular or T-shaped locking nut 12, and the locking nut 12 connects the connecting rod 10 to the main board 2 or the side board 3 through a screw.

[0044] The rectangular or T-shaped locking nut 12 directly contacts the adjusting spring 11 and keeps the adjusting spring 11 in a compressed state all the time. The rectangular or T-shaped locking nut 12 contacts the reinforcing groove I 7 on the main board 2 and the reinforcing groove II 8 on the side board 3, and the reinforcing groove I 7 and the reinforcing groove II 8 limit the rectangular or T-shaped locking nut 12.

[0045] The screw on the locking nut 12 is connected to the reinforcing groove I 7 on the main board 2 or the reinforcing groove II 8 on the side board 3 through a through hole opened on the rectangular or T-shaped locking nut 12.

[0046] In this embodiment, both the reinforcing groove I 7 and the reinforcing groove II 8 can be of a multi-step groove structure. The reinforcing groove I 7 includes an outer groove and an inner groove. The inner groove is arranged inside the outer groove. The outer wall of the inner groove is communicated with the outer groove, and the inner wall of the inner groove is communicated with the cavity 13. Groove openings are respectively opened on the upper and lower inner walls of the inner groove, and the groove openings are communicated with the outer groove.

[0047] The groove openings divide the upper and lower inner walls of the inner groove into two steps. The lower step is denoted as the second step, denoted as A2. The side wall of the groove opening is a three-level side wall, denoted as B3. The bottom of the outer groove is the first step, denoted as A1. The side wall of the outer groove is denoted as a first-level side wall, denoted as B1. The side wall of the inner groove is a second-level side wall, denoted as B2.

[0048] The structure of the reinforcing groove II 8 is the same as that of the multi-step groove structure of the reinforcing groove I 7 and will not be described repeatedly here.

[0049] The rectangular or T-shaped locking nut 12 contacts the second step A2 on the reinforcing groove I 7 on the main board 2 and the reinforcing groove II 8 on the side board 3. The screws on the locking nut 12 can be threadedly connected to the threaded counterbores opened on the first-level side wall B1, the second-level side wall B2, and the three-level side wall B3 respectively.

[0050] The reinforcing groove I 7 and the reinforcing groove II 8 are arranged in a multi-step groove structure. On the one hand, the positioning of the locking nut 12 can be placed inside and does not need to appear on the surface of the frame. On the other hand, if the locking nut 12 is only placed on the surface of the frame, it will be difficult to adjust the locking nut 12 in the width direction.

[0051] The connection of the fastener 4 to the main board 2 and the side board 3 is not limited to threaded connection and dowel pin connection.

[0052] Embodiment 2

[0053] Combined with the above-mentioned tool for reinforcing the shell of a frame-type precision casting, for the convenience of applying it to small-sized frame-type castings, the assembly method of the device for reinforcing the shell according to the present invention that can achieve rapid installation will be described. First, the casting is tightly wound with a high-temperature resistant material such as asbestos felt, and placed on the bottom plate 1, and the gate position is aligned with the through hole 101 on the bottom plate 1. The main board 2 is inserted into the innermost side of the bottom plate 1 through the installation groove I5 on the bottom plate 1, and the installation groove I5 is in the shape of a dovetail groove. The remaining installation grooves I5 on the bottom plate 1 can be filled with T-shaped blocks that completely match the shape of the installation groove I5, or they can not be filled. The side plate 3 is inserted into the U-shaped groove inside the main board through the installation groove II6 on the main board 2. The installation groove II6 can be a U-shaped groove structure, and the installation groove II6 is connected to the main board 2.

[0054] According to the special-shaped parts of the frame-type casting, such as irregular grooves, the irregular grooves that cannot be in complete contact with the wound asbestos felt are filled completely with a flexible material, and then the groove is tightened with the fastener 4. According to the specific position of the groove or other special-shaped structures, it can be tightened specifically through the reinforcing groove I7 on the main board 2 and the reinforcing groove II8 on the side plate 3. In this embodiment, both the reinforcing groove I7 and the reinforcing groove II8 are rectangular groove structures, and through the parallel arrangement of the reinforcing groove I7 on the main board 2 and the reinforcing groove II8 on the side plate 3, different positions at approximately the same height or different positions at different heights of the casting can be tightened simultaneously.

[0055] The fastener 4 is connected to the main board 2 or the side plate 3 through a rectangular or T-shaped locking nut 12 and a screw provided on the locking nut 12. The rectangular or T-shaped locking nut 12 is in direct contact with the adjusting spring 11, and keeps the spring in a compressed state all the time. The rectangular or T-shaped locking nut 12 is in contact with the reinforcing groove I7 - rectangular groove structure on the main board 2 and the reinforcing groove II8 - rectangular groove structure on the side plate 3, and the reinforcing groove I7 and the reinforcing groove II8 limit the rectangular or T-shaped nut 12.

[0056] The screw on the locking nut 12 is connected to the reinforcing groove I7 on the main board 2 or the reinforcing groove II8 on the side plate 3 through a through hole opened on the rectangular or T-shaped locking nut 12. The two sides of the rectangular groove structure on the main board 2 and the side plate 3 are denoted as side walls B. The rectangular or T-shaped locking nut 12 is in contact with the main board 2 and the side plate 3. The screw on the locking nut 12 is threadedly connected to the threaded counterbore opened on the side wall.

[0057] The connection of the fastener 4 to the main board 2 and the side plate 3 is not limited to threaded connection and positioning pin connection.

[0058] This patent avoids the limitation that the sand collapses during baking at a certain temperature. It uses metal materials and high-temperature resistant materials, can be applied to high-temperature heating, and avoids environmental pollution.

[0059] In the working state of this patent, the adjusting spring is in a compressed state, which can eliminate the problem of inconsistent shrinkage ratios between the fasteners and the casting line / body.

[0060] This patent completely avoids the rupture of all weak parts by stuffing refractory asbestos felt and through the targeted reinforcement of fasteners.
