Description

Technical Field

[0001] This invention belongs to the field of shot blasting machine parts processing, specifically a processing equipment and method for shot blasting machine parts. Background Technology

[0002] Shot blasting machines, as core equipment for surface cleaning and strengthening of workpieces in industries such as casting and machining, rely heavily on the processing quality of their core components for efficiency, processing accuracy, and operational stability. Among these components, the shot distribution wheel, a key and vulnerable part of the shot blasting assembly, plays a crucial role in receiving, pre-accelerating, and uniformly distributing the shot. It is essential for ensuring a regular shot trajectory and consistent impact force. During shot distribution wheel production, molds are typically used for forming. These molds include an upper mold and a lower mold, with an inner core mold placed between them. The upper mold, lower mold, and inner core mold form the wheel portion of the shot distribution wheel. Additionally, the inner core mold has protrusions at equal angles around its circumference to facilitate the formation of the shot distribution grooves on the circumference of the shot distribution wheel. However, the following defects still exist: The inner core mold is fixed, making it difficult to adjust the number of protrusions in its circumferential direction. During production, the inner core mold needs to be replaced depending on the number of shot-dividing grooves required on the shot-dividing wheel. This necessitates preparing various inner core molds with different numbers of protrusions. Furthermore, when damaged, the entire inner core mold needs to be replaced, resulting in high equipment costs. Summary of the Invention

S5. Molding: The molten metal is fed into the mold cavity through the feed pipe. After the molten metal cools and solidifies, the mold is disassembled and the material is unloaded.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a core block with circumferentially oriented forming parts at equal angles. The circumferential forming parts include groove forming parts and circumferential supplementary parts. This allows for adjustment of the shot distribution groove setting based on the number of groove forming parts used. The groove forming parts and the circumferential supplementary parts form a closed loop outside the core block, improving the shot distribution wheel forming effect and facilitating replacement when damaged, thus saving costs. This invention uses positioning cavity strips set at equal angles on the bottom wall of a fixed cylinder. After the inner core mold is installed, the positioning cavity strips are inserted into the corresponding lower and upper positioning grooves to achieve horizontal positioning of the core block and each circumferential forming part. When the pull plate pulls each vertical plate downward, it can push the first locking block into the corresponding first locking groove to achieve longitudinal positioning of the core block and each circumferential forming part, thereby improving the stability of the shot-forming wheel. This invention, when the pull plate pulls each vertical plate downward, can push the first locking block into the corresponding first locking slot, thereby achieving longitudinal positioning of the core block and each circumferential forming part. At the same time, the first locking block generates pressure on the mounting block towards the circumferential side of the fixed cylinder, improving the tightness between the arc plate and the outer wall of the core block, and improving the forming effect of the shot-forming wheel. In this invention, the top cover is installed on the top of the fixed cylinder, so that a mold cavity is formed between the fixed cylinder, the top cover and the inner core mold. The protrusion is in close contact with the inner wall of the fixed cylinder, which facilitates the formation of the shot distribution groove, while the bottom block is inserted into the top groove, which facilitates the formation of the shot inlet. In this invention, during top cover installation, two positioning rods are inserted into two positioning slots respectively, and the rotating block is rotated to a position where the side block and the side slot are misaligned. When the pull plate moves down, it pulls the top cover and presses it against the top of the fixed cylinder, improving the forming stability of the shot distribution wheel. At the same time, it pushes the push block to move downward, so that the second locking block is locked into the second locking slot, and the core block and the top cover are locked together and fixed, further improving the forming stability of the shot distribution wheel.

After the inner core mold 3 is installed, the positioning cavity strips 1411 are positioned accordingly. Inserted into the corresponding lower positioning groove 34 and upper positioning groove 323, the core block 31 and each circumferential forming part 32 are horizontally positioned. When the pull plate 142 pulls each vertical plate 14113 downward, it can push the first locking block 1417 into the corresponding first locking groove 324, thereby achieving longitudinal positioning of the core block 31 and each circumferential forming part 32, improving the stability of the shot-separating wheel forming. At the same time, the first locking block 1417 generates pressure on the mounting block 322 towards the circumferential side of the fixed cylinder 11, improving the tightness between the arc plate 321 and the outer wall of the core block 31, and improving the shot-separating wheel forming effect.

[0020] Depend on Figures 6-7The upper mold 2 includes a top cover 21 disposed above the fixed cylinder 11. A feed pipe 22 is eccentrically mounted on the top cover 21. A bottom block 23 is mounted on the bottom end of the top cover 21. A mold cavity is formed between the fixed cylinder 11, the top cover 21, and the inner core mold 3. The protrusion 325 is tightly attached to the inner wall of the fixed cylinder 11 to facilitate the formation of the shot chute. The bottom block 23 is inserted into the top groove 35 to facilitate the formation of the shot inlet. The inner cavity of the bottom block 23 is connected to the top of the top cover 21. Second side guide grooves are symmetrically opened on both sides of the bottom block 23. 24. A push block 25 is movably installed inside the bottom block 23.

Positioning pressure-bearing components 29 are symmetrically installed on both sides of the pressure plate 28. The positioning and pressure-bearing component 29 includes side arms 291 symmetrically installed on both sides of the pressure plate 28. A positioning rod 292 is fixedly installed at the bottom end of the side arm 291. A limiting groove 293 is formed at the bottom end of the positioning rod 292. A rotating block 294 is provided below the positioning rod 292. A limiting block 295 is fixedly installed at the top end of the rotating block 294. The limiting block 295 is rotatably connected to the limiting groove 293. A side block 296 is fixedly installed on one side of the limiting block 295. The top cover 21 is installed... At the same time, the two positioning rods 292 are inserted into the two positioning slots 1442 respectively, and the rotating block 294 is rotated to the position where the side block 296 and the side groove 1443 are misaligned. When the pull plate 142 moves down, it pulls the top cover 21 and the top of the fixed cylinder 11 to press together, thereby improving the forming stability of the shot distribution wheel. At the same time, it pushes the push block 25 to move down, so that the second locking block 26 is locked into the second locking groove 36, thereby locking and fixing the core block 31 and the top cover 21, and further improving the forming stability of the shot distribution wheel.

[0021] Working principle: During use, the core block 31 is adjusted according to the number of shot-separating grooves required on the shot-separating wheel. In this application, the core block 31 has eight circumferential mounting grooves 33, which can produce shot-separating wheels with 2, 4, and 8 shot-separating grooves. When the shot-separating wheel has 2 shot-separating grooves, 2 groove forming parts 32a and 6 circumferential supplementary parts 32b are selected for installation. When the shot-separating wheel has 4 shot-separating grooves, 4 groove forming parts 32a and 4 circumferential supplementary parts 32b are selected for installation. When the shot-separating wheel has 8 shot-separating grooves, 8 groove forming parts 32a are selected for installation, so that the groove forming parts 32a can be set at equal angles on the outside of the core block 31 to achieve equal angle setting of the shot-separating grooves. After selection, the mounting block 322 on the arc plate 321 is inserted into the mounting groove 33 in the circumferential direction of the core block 31, so that the arc plate 321 is in close contact with the outer wall of the core block 31, thereby connecting the arc plates 321 in the circumferential direction of the core block 31 end to end to form a cylindrical shape, which is tightly attached to the outside of the core block 31. After installation, the core block 31 is positioned according to the corresponding positions of the lower positioning groove 34 and the positioning cavity strip 1411. The inner core mold 3 is then placed into the fixed cylinder 11, so that the positioning cavity strip 1411 is inserted into the lower positioning groove 34 and the upper positioning groove 323 on the mounting block 322 in the mounting groove 33, thereby positioning and fixing the core block 31 and each circumferential forming part 32, and completing the installation. Then, a top cover 21 is installed on the top of the fixed cylinder 11, so that the bottom block 23 at the bottom of the top cover 21 is inserted into the top groove 35 at the top of the core block 31, and the positioning rods 292 on both sides are inserted into the positioning slots 1442 of the side plates 1441 on both sides of the pull plate 142. When the rotating block 294 passes through the positioning slot 1442, the side block 296 needs to be rotated to the position corresponding to the side groove 1443. After installation, the rotating block 294 is rotated so that the side block 296 is rotated to the position offset from the side groove 1443. Then, the hydraulic cylinder 143 is activated, pulling the pull plate 142 downwards, resulting in the following actions: First, the vertical plate 14113 is pulled downward, which in turn pulls the rack 14112 downward. Since the rack 14112 is meshed with the gear 14111, it drives the extrusion cam 1419 to rotate and push the pressure plate 1412 downward. Then, through the first connecting rod 1418, the first locking block 1417 is pushed outward, so that the first locking block 1417 is locked into the first locking groove 324, thereby achieving longitudinal positioning of the core block 31 and each circumferential forming part 32. In addition, pressure is generated on the mounting block 322 towards the axis of the core block 31, so that the arc plate 321 can be tightly attached to the outer wall of the core block 31. In addition, since the side block 296 is misaligned with the side groove 1443, when the pull plate 142 moves downward, it exerts downward pressure on the side block 296, which in turn pulls the pressing plate 28 downward. After the bottom wall of the pressing cylinder 210 contacts the top wall of the top cover 21, it exerts downward pressure on the top cover 21, pressing the top cover 21 and the fixed cylinder 11 together. At the same time, the push block 25 moves downward along the bottom block 23, and pushes the two second locking blocks 26 outward through the two second connecting rods 27 to lock into the second locking groove 36, thereby locking and fixing the top cover 21 and the core block 31, improving the tightness of the connection and improving the molding effect. After the mold is assembled, molten metal is introduced into the mold through the feed pipe 22. The molten metal cools and solidifies inside the mold. The presence of the bottom block 23 forms a shot inlet on the workpiece, and the presence of each protrusion 325 forms a shot distribution groove on the workpiece. Finally, the hydraulic cylinder 143 drives the pull plate 142 to move upward and rotates the rotating block 294 to the position where the side block 296 corresponds to the side groove 1443. The lower mold 1, the upper mold 2, and the inner core mold 3 are then disassembled, and the cooled and solidified shot distribution wheel can be taken out.
