Description

Technical Field

[0001] This utility model relates to the field of casting production technology, and in particular to an adjusting clamping mechanism for casting shaping. Background Technology

[0002] During the cooling process of castings, the different wall thicknesses result in inconsistent cooling rates, leading to stress in the last solidified areas and causing casting deformation. When the wall thickness difference is too large, the thinner areas cool rapidly while the thicker areas cool more slowly, causing uneven cooling, hindering normal shrinkage, and also causing casting deformation. Therefore, some castings require shaping equipment for shaping after production.

[0003] Existing forming devices mainly apply pressure to the deformed position using hydraulic equipment. Since the position of the casting needs to be frequently adjusted during the forming process, and the support position also needs to be adjusted, it is extremely inconvenient to manually control the position of large castings and frequently rotate them. Therefore, it is necessary to make it easy to adjust the casting while also being able to change the support position and the distance between the support blocks to ensure the forming effect.

Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-4 The diagram shows an adjusting clamping mechanism for casting shaping, comprising an operating table 1, a support mechanism 2, a first clamping mechanism 3, a second clamping mechanism 4, and a handle 5. The support mechanism 2 is fixedly mounted on the top of the operating table 1. The first clamping mechanism 3 and the second clamping mechanism 4 are fixedly mounted on the upper surface of the operating table 1 and are located on the outer sides of the support mechanism 2. The first clamping mechanism 3 and the second clamping mechanism 4 include a guide seat 31, a sliding frame 32, a sleeve 33, a guide rod 34, a first spring 35, a connecting pipe 36, a rotating shaft 37, a clamping seat 38, a pressure plate 39, a screw 310, and a first spring 5. Two springs 311, a sliding frame 32 is locked inside the guide seat 31, a sleeve 33 is sleeved on the top outer side of the sliding frame 32, a guide rod 34 is fixedly set inside the sleeve 33, a first spring 35 is set between the top inner side of the sleeve 33 and the top of the sliding frame 32, a connecting pipe 36 is fixedly set on the top of the sleeve 33, a rotating shaft 37 is movably connected to the connecting pipe 36, a clamping seat 38 is fixedly set at one end of the rotating shaft 37, a pressure plate 39 is locked inside the clamping seat 38, a screw 310 is fixedly set at the bottom of both ends of the pressure plate 39, and a second spring 311 is sleeved outside the screw 310.

[0025] Specifically, the support mechanism 2 includes an adjustment frame 21, a support base 22, and a handle 23. The support base 22 is mounted on the top of the adjustment frame 21, and the handle 23 is fixedly mounted on the outside of the support base 22. In the second clamping mechanism 4, the length of the rotating shaft 37 is longer than the length of the rotating shaft 37 in the first clamping mechanism 3. The handle 5 is fixedly mounted on the tail end of the rotating shaft 37 in the second clamping mechanism 4. A limit strip is fixed on the inner side of the top of the support base 22. A guide limit groove that cooperates with it is opened laterally on the surface of the adjustment frame 21. The two ends of the pressure plate 39 pass through and extend to the outside of one side of the clamping base 38. The two sides of the clamping base 38 are provided with pressure grooves that cooperate with the two ends of the pressure plate 39. The bottom of the screw 310 passes through and extends to the outside of the bottom of the clamping base 38. A clamping nut is provided on the outside of the screw 310 at the bottom of the clamping base 38. A sliding plate is provided on the bottom of the sliding frame 32. A sliding groove that cooperates with it is opened on the inner side of the guide seat 31. A waist-shaped hole that cooperates with the guide rod 34 is opened vertically on the surface of the sliding frame 32.

[0026] In this embodiment, the casting is first installed. After the sliding bracket 32 ​​is slid into the guide seat 31 to a suitable position, both ends of the casting are respectively clamped into the clamping seat 38. Then, the locking nut on the surface of the screw 310 is tightened. Due to the action of the second spring 311, the pressure plate 39 is in an upward state, which facilitates the installation of the casting end. Tightening the locking nut can control the pressure plate 39 to press down, thereby realizing the effective clamping of the casting end by the pressure plate 39, and completing the casting installation work.

[0027] Further, the shaping process begins. According to the required support position, the position of the support seat 22 on the surface of the adjusting frame 21 can be adjusted by holding the handle 23, thereby changing the support point position and the distance between the support points. After the hydraulic pressure is applied to the surface of the casting, the pressure on the casting will cause the sleeve 33 to move down on the top of the sliding frame 32, causing the first spring 35 to be compressed and contracted until the casting contacts the top of the support seat 22. Further pressure is applied to achieve the shaping process. The position adjustment of the sliding frame 32 in the guide seat 31 can be controlled by operating the handle 5, and the rotation of the handle 5 can control the rotation of the rotating shaft 37 in the connecting pipe 36. The pressure surface is adjusted by rotation. The ideal pressure shaping effect is achieved by adjusting the pressure area, the pressure surface, the support point position, and the distance between the support points.
