Description

Technical Field

[0001] The utility model discloses a casting riser impact removal device, which belongs to the field of casting processing. Background Art

[0002] After the casting is cast, a riser will be formed on its surface. The riser needs to be removed by impact. An impact block is installed at the movable end of the hydraulic cylinder. When the movable end of the hydraulic cylinder is extended, the impact block is driven to move so that the impact block squeezes the riser of the casting to achieve the purpose of removing the riser of the casting by impact. The movable end of the hydraulic cylinder is generally connected and fixed to the impact block by multiple screws. When the impact block squeezes the riser of the casting, the reaction force received by the impact block close to the surface of the casting is greater than the reaction force received by the impact block away from the surface of the casting, that is, the two sides of the connection between the hydraulic cylinder and the stamping block are subjected to unbalanced reaction forces, and the strength requirements of the connection between the movable end of the hydraulic cylinder and the impact block are relatively high. Utility Model Content

[0005] Furthermore, an insert plate is connected and fixed to one end of the transverse strip close to the impact block, the middle position of the upper surface of the impact block is recessed downward to form a rectangular groove, the insert plate is inserted in the rectangular groove, and the insert plate is connected and fixed to the impact head by a positioning screw.

[0006] Furthermore, two threaded holes are provided at the upper position of one side of the impact block facing the column rod, the threaded holes are communicated with the rectangular groove, and the positioning screws are threadedly connected in the threaded holes.

[0007] Furthermore, the plug plate and the transverse strip are an integrally formed structure, and the plug plate and the transverse strip are arranged perpendicular to each other.

[0008] Furthermore, a step groove is provided at the lower position of one side of the impact block facing away from the column rod, and a guard plate is provided in the step groove, and the thickness of the guard plate is the same as the depth of the step groove; two through holes are provided at the lower position of one side of the impact block facing the column rod, and the through holes are communicated with the step groove; two threaded blind holes aligned with the through holes are provided on one side of the guard plate, and connecting screws are inserted in the through holes, and one end of the connecting screw is threadedly connected in the threaded blind hole.

[0010] Beneficial effects of the utility model:

[0011] 1. Use the positioning screws to install the plug plate in the rectangular groove to complete the assembly of the cross-slat and the impact block. Connect the limit screws through the screw holes on the cross-slat so that the lower end of the limit screws extends into the limit holes on the column. At this time, the reaction force received by the impact block acts on the column through the cross-slat and the limit screws, so that the reaction force received by the connection between the impact block and the column is dispersed on the column, reducing the strength requirements for the connection between the impact block and the column and improving the stability of the structure.

[0012] 2. Install a guard plate in the stepped groove. When the hydraulic cylinder drives the impact block to contact the riser of the casting, the guard plate directly contacts the riser of the casting. When the guard plate is worn, the connecting screws can be removed to replace the guard plate without replacing the entire impact block, thereby reducing the cost of parts replacement.
