TECHNICAL FIELD
[0001] The utility model relates to mechanical type clamping compression tool, especially a cantilever type compression tool. BACKGROUND
[0002] When the small bottom pouring type smelting casting furnace is used, the pouring gate of disposable ceramic pouring shell needs to be fixed and compressed in the back center annular matching groove of the pouring hole plate. Because the shape, size and structure of the pouring shell are not fixed, it is impossible to directly apply fastening force to the proximal end of the pouring gate matching surface. The compression tool in the prior art is welded together by two cantilevers and a base plate. Although the tool can fix and compress the pouring gate of the pouring shell on the back of the pouring hole plate through the two cantilevers, the tool has the following problems: first, the two cantilevers need to be welded on the base plate, which requires a long processing cycle; second, the distance between the two cantilevers and the size of the base plate are fixed, and after welding, the size cannot be adjusted according to pouring shells of different shapes and sizes. When pouring shells of different shapes and sizes need to be fixed, tools of different sizes need to be customized. SUMMARY

[0005] In order to simultaneously adjust the height of the first cantilever and the second cantilever, preferably, the adjusting mechanism is arranged on the connecting part.
[0006] In order to adjust the fixed height of the first cantilever and the second cantilever, preferably, the adjusting mechanism comprises an adjusting bolt and a nut, the connecting part is provided with a through hole for the adjusting bolt to pass through, the first end of the adjusting bolt is radially protruded to form a head, the second end passes through the through hole, the adjusting bolt is provided with an external thread, the nut is provided with an internal thread matched with the external thread, a spacing part is formed between the nut and the head, and the height of the spacing part can be adjusted by rotating the nut, and the connecting part is limited in the spacing part. In this way, when the height of the casting shell is low, rotating the nut makes the nut close to the head, so that the height of the connecting part is reduced, and the fixed height of the first cantilever and the second cantilever is reduced; and when the height of the casting shell is high, rotating the nut makes the nut away from the head, so that the height of the connecting part is increased, and the height of the first cantilever and the second cantilever is increased.
[0007] Preferably, a groove part is formed in the connecting part by concave, the first cantilever and the second cantilever are located at the top end of the groove part and extend along the length direction of the groove part, and the through hole is arranged at the bottom of the groove part.
[0008] In order to enhance the strength of the tooling, preferably, the groove part is semicircular or semi-elliptical. In this way, the whole groove part is arc-shaped, which avoids the tooling from being broken due to stress concentration.
[0009] In order to adapt to casting shells with different shapes and sizes, preferably, the distance between the first cantilever and the second cantilever gradually increases along the direction away from the connecting part. When the size of the sprue of the casting shell is large, the end away from the connecting part can be used to fix the casting shell, and when the size of the sprue of the casting shell is small, the end close to the connecting part can be used to fix the casting shell.
[0010] In order to facilitate manufacturing, preferably, the first cantilever, the second cantilever and the connecting part are integrally formed. The integrally formed first cantilever, the second cantilever and the connecting part reduce the welding steps, reduce the processing steps and shorten the manufacturing period.
[0011] Compared with the prior art, the tooling has the advantages that: the tooling can adjust the fixed height of the tooling through the adjusting mechanism, so as to be suitable for casting shells with different shapes and sizes, and has good universality; meanwhile, the first cantilever, the second cantilever and the connecting part of the tooling are integrally formed, the structure is simple, the manufacturing is convenient, and the complicated processing steps during manufacturing are avoided.

[0016] The utility model will be described in further detail below in combination with the drawings.
[0017] As Figures 1-4 shown, it is a preferred embodiment of the utility model. The first cantilever 1, the second cantilever 2, the connecting portion 3 connecting the first cantilever 1 and the second cantilever 2 and the adjusting mechanism 5 capable of adjusting the fixed height of the first cantilever 1 and the second cantilever 2 of the cantilever type pressing tool of the embodiment. Wherein, the first cantilever 1 and the second cantilever 2 are arranged at intervals and form the space 4 capable of fixing the inside of the pouring shell between the first cantilever 1 and the second cantilever 2. In the embodiment, the first cantilever 1, the second cantilever 2 and the connecting portion 3 are integrally formed, the recessed groove portion 32 of semicircle is formed in the middle of the connecting portion 3, the first cantilever 1 and the second cantilever 2 are located at the top of the recessed groove portion 32 and extend along the length direction of the recessed groove portion 32, the work of this shape can be directly line-cutting blanking processed according to the external dimension by industrial steel pipe, the raw material source is wide, the cost is low, and the processing is simple. The interval between the first cantilever 1 and the second cantilever 2 gradually increases along the direction away from the connecting portion 3, the gradually changing cantilever design makes that the cantilever type pressing tool can be suitable for pouring shells of different shapes and different sizes, when the pouring size of the pouring shell is larger, then the end away from the connecting portion 3 can be used to fix the pouring shell, and when the pouring size of the pouring shell is smaller, then the end close to the connecting portion 3 can be used to fix the pouring shell.
[0018] The specific structure of the adjusting mechanism 5 is referred to Figures 2-4The adjusting mechanism 5 comprises an adjusting bolt 51 and a nut 52. The connecting part 3 is provided with a through hole 31 through which the adjusting bolt 51 passes. The through hole 31 is arranged at the bottom of the groove part 32. The first end of the adjusting bolt 51 is radially protruded to form a head 53. The second end of the adjusting bolt 51 passes through the through hole 31. The adjusting bolt 51 is provided with an external thread. The nut 52 is provided with an internal thread matched with the external thread of the adjusting bolt 51. The nut 52 and the head 53 form a spacing part 54 therebetween. The height of the spacing part 54 can be adjusted by rotating the nut 52. The connecting part 3 is limited in the spacing part 54. When the height of the cast shell is low, the nut 52 is adjusted to be close to the head 53 by rotating the nut 52. Thus, the height of the connecting part 3 is reduced, and the fixed height of the first cantilever 1 and the second cantilever 2 is reduced. When the height of the cast shell is high, the nut 52 is adjusted to be far away from the head 53 by rotating the nut 52. Thus, the height of the connecting part 3 is increased, and the height of the first cantilever 1 and the second cantilever 2 is increased. Therefore, the tooling can be applied to cast shells with different heights.
[0019] In summary, the method for using the cantilever pressing tooling is as follows:
[0020] The cast shell is installed on the annular groove on the back of the gating plate. The back of the gating plate is provided with a positioning frame adjacent to the annular groove. The height of the tooling is adjusted according to the height of the sprue of the cast shell. The tooling is pushed into the positioning frame from outside the positioning frame, and the first cantilever 1 and the second cantilever 2 are respectively contacted with the two ends of the sprue of the cast shell. The connecting part 3 is knocked along the length direction of the groove part 32 to further push the tooling into the positioning frame. At this time, the first cantilever 1 and the second cantilever 2 apply force to the cast shell and press the cast shell towards the gating plate. When it is needed to remove the tooling, the first cantilever 1 or the second cantilever 2 is knocked along the length direction of the groove part 32, or the sprue of the cast shell is knocked to be broken. Thus, the tooling can be removed from the positioning frame.
