Description

Technical Field

[0001] This invention relates to the field of shot blasting, and more particularly to a grinding and polishing device and method for iron accessories. Background Technology

[0002] Polishing and grinding of batches of iron accessories is generally carried out using shot blasting. Shot blasting is performed by projecting high-speed shot onto the surface of the iron accessories to achieve grinding, while the repeated collisions of the shot separate the waste material from the iron accessories. Shot blasting is a highly efficient mechanical surface treatment technology that thoroughly removes oxide scale, rust, and dirt through impact, and can generate compressive stress on the metal surface.

[0003] In the current shot blasting process, after shot blasting, iron fittings still need to undergo high-pressure blowing for cleaning. The purpose of this cleaning is to remove impurities (metal slag) and shot residue remaining on the surface of the iron fittings. The cleaning structure includes a high-pressure airflow nozzle and a roller brush. The high-pressure airflow nozzle sprays high-pressure airflow, which works in conjunction with the rolling roller brush to clean the surface of the iron fittings.

[0004] However, for iron fittings with multiple pits on their surface, such as holes and other pits, the pits can accumulate a lot of projectiles and impurities. When blown by high-pressure airflow, these projectiles and impurities will be dispersed and fall into other pits, making the cleaning process cumbersome and incomplete.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the aforementioned shortcomings, the present invention aims to provide a grinding and polishing device and method for iron accessories, which thoroughly cleans iron accessories with multiple pits on their surface. Through the ingenious combination of high-pressure nozzles and rollers, and the design of guide plates and guide grooves, the accurate introduction and storage of shot are achieved, and the shot is conveniently discharged from the outlet. This solves the problem of shot dispersing under high-pressure airflow and accumulating again in other pits, and achieves efficient cleaning of residual shot and impurities on the surface of iron accessories.

[0007] To achieve the above objectives, the present invention provides a grinding and polishing device for iron accessories, comprising: a high-pressure nozzle for spraying airflow onto the iron accessories; at least one roller body located to the side of the high-pressure nozzle, the roller body having a storage space and a guide groove extending from the side wall to the storage space; a guide plate provided on the outer wall of the roller body, which, after the roller body is driven to rotate, cooperates with the guide plate to guide the shot blown by the airflow through the guide groove into the storage space; an outlet provided on the roller body for discharging the shot collected in the roller body; and a cleaning part provided on the surface of the roller body for contacting the iron accessories when it rotates.

[0008] According to the present invention, the high-pressure nozzle and the roller are both mounted on a movable seat, which is driven to move relative to the iron accessory placement table.

[0009] According to the present invention, the iron accessory grinding and polishing device is rotatably mounted on the roller body and opens / closes the guide groove when driven; when the guide plate is in the open state, it guides the shot; when the outlet is discharging the shot, the guide plate enters the closed state.

[0010] According to the iron accessory grinding and polishing device of the present invention, the guide plate is an arc-shaped plate structure, and its curvature is consistent with the curvature of the outer wall of the roller.

[0011] According to the present invention, the iron accessory grinding and polishing apparatus has the cleaning section disposed on the side wall of the guide plate away from the guide groove.

[0012] According to the iron accessory grinding and polishing device of the present invention, the roller body is provided with multiple sets of guide grooves, which are distributed in a ring around the axis of the roller body. Each guide groove extends along the axial direction of the roller body, and all sets of guide grooves are connected to the storage space. The guide plate is provided with multiple sets of guide grooves, and they correspond one-to-one.

[0013] According to the iron accessory grinding and polishing device of the present invention, the guide groove is a slanted straight groove or a slanted arc groove; its radial offset direction corresponds to the rotation direction of the roller.

[0014] According to the iron accessory grinding and polishing device of the present invention, a drive rod is installed inside the roller storage space, which is driven to reciprocate along the roller axis; an adapter is installed on the roller, the adapter including an "L"-shaped connecting rod, the middle of the connecting rod is hinged to the roller, one end of the connecting rod is a connecting end, and the other end is a driving end; the guide plate has a groove, and the connecting end is rotatably installed in the groove; the end of the drive rod has a boss; when the drive rod moves, the boss engages with the driving end to drive the connecting rod to rotate, and further drive the guide plate to rotate.

[0015] According to the present invention, the iron accessory grinding and polishing device has two sets of rollers, and the high-pressure nozzle is disposed between the two sets of rollers.

[0016] According to the present invention, the iron accessory grinding and polishing device is provided with a shot nozzle for ejecting shot on the movable seat.

[0017] This invention discloses a method for grinding and polishing iron accessories, comprising the following steps: The iron fittings are fed into the polishing equipment mentioned above, and the polishing equipment is used to propel high-speed shot onto the surface of the iron fittings for grinding and polishing.

The roller body is driven to rotate, and the bullets and debris raised by the airflow are guided by the guide plate on the outer wall and guided into the storage space inside the roller body for temporary storage. At the same time, the cleaning part on the surface of the roller body continuously contacts the surface of the iron accessories as it rotates, sweeping away the residual bullets and grinding impurities. Once a certain amount of shot has been collected in the roller body, it is discharged uniformly through the pre-set discharge port of the roller body.

[0025] See Figure 1 , Figure 2 , Figure 3 This invention provides a grinding and polishing device and method for iron accessories. The grinding and polishing device includes a chamber 1, and the chamber 1 is provided with: A high-pressure nozzle 2 is used to spray airflow onto the iron fittings. The high-pressure nozzle 2 is connected to an air supply component via a pipe. This air supply component can be an air pump. The air pump generates a high-pressure airflow, which is sprayed by the high-pressure nozzle 2 onto the iron fittings, blowing away shot and impurities adhering to the surface of the iron fittings. At least one roller 3 is located to the side of the high-pressure nozzle 2. The roller 3 has a storage space 5 and a guide groove 4 extending from the side wall into the storage space 5.Figure 5 (As shown); the outer wall of the roller body 3 is provided with a guide plate 6. After the roller body 3 is driven to rotate, the guide plate 6, together with the guide plate 6, guides the projectile blown by the airflow through the guide groove 4 into the storage space 5; the roller body 3 is provided with a discharge port 7 ( Figure 8 As shown), it is used for discharging the projectiles collected in the storage space 5; the roller body 3 is provided with a cleaning section 8 ( Figure 4 As shown), the cleaning part 8 can contact the iron attachment when the roller 3 rotates, so as to clean the stubborn impurities adhering to the surface of the iron attachment. The cleaning part 8 can be a structure with cleaning and sweeping effect such as hair or flexible cotton, such as a brush.

[0026] During operation, the high-pressure nozzle 2, driven by an air pump, sprays a powerful airflow directly onto the surface of the iron attachment to be cleaned. As this airflow rapidly agitates the shot remaining in the pits of the iron attachment, the shot disperses in all directions. Simultaneously, the roller 3 located to the side of the high-pressure nozzle 2 rotates, and the guide plate 6 on its outer wall catches the dispersed shot, guiding it accurately through the guide groove 4 into the storage space 5 of the roller 3, and then discharging it from the outlet 7.

[0027] This invention can effectively clean iron attachments with multiple pits on their surface using shot. Through the ingenious combination of the high-pressure nozzle 2 and the roller 3, and the design of the guide plate 6 and the guide groove 4, the accurate introduction and storage of shot, as well as its final discharge, are achieved.

[0028] See Figure 2 and Figure 3 In some embodiments of the present invention, the equipment can be moved either by the iron attachments or by the processing components during shot blasting and cleaning. For example, in this embodiment, after the iron attachments are fixed in position, the processing components move relative to the iron attachments. Specifically, the high-pressure nozzle 2 and the roller 3 are both mounted on a movable base 9, which moves relative to the iron attachment placement platform. The movable base 9 is driven by a displacement mechanism in the X, Y, and Z directions. This displacement mechanism can be a motor-driven lead screw structure, rack and pinion structure, etc. The high-pressure nozzle 2 is connected to an air supply component via a flexible hose. With the iron attachments fixed in position, the movable base 9 moves the high-pressure nozzle 2 and the roller 3 along a preset trajectory, ensuring that every part of the iron attachment surface is uniformly blown and cleaned, increasing the flexibility of the equipment.

[0029] Preferably, the movable base 9 is equipped with a shot nozzle 15 for ejecting shot. The shot nozzle 15 is connected to a shot supply assembly, i.e., a shot supply pump, via a hose. The shot nozzle 15 and the high-pressure nozzle 2 can be selectively used in operation. During the polishing of the iron accessories, the movable base 9 moves, and the shot nozzle 15 can spray shot onto the surface of the iron accessories. The impact force of the shot further removes stubborn impurities and oxide layers from the surface of the iron accessories. Subsequently, the high-pressure nozzle 2 performs high-pressure gas purging, forming a continuous cleaning process of "shot impact - high-pressure purging," significantly improving the cleaning effect and processing efficiency of the equipment on complex iron accessory surfaces. At the same time, the above structure also increases the integration of the equipment and reduces the footprint of components.

[0030] See Figure 4 , Figure 5 and Figure 6 In some embodiments of the present invention, the guide plate 6 is rotatably mounted on the roller body 3, and rotates under drive to open / close the guide groove 4; the guide plate 6 in the open state performs the guiding function; when the discharge port 7 is discharging the shot, the guide plate 6 enters the closed state. The rotatable design of the guide plate 6 allows for flexible control of the opening and closing of the guide groove 4 according to actual needs during the cleaning process. When shot collection is required, the guide plate 6 opens to ensure that the shot can smoothly pass through the guide groove 4 into the storage space 5; when the shot in the storage space 5 needs to be discharged, the guide plate 6 closes to prevent the shot from scattering and falling out again during the discharge process, thereby improving the efficiency of shot recovery.

[0031] In some embodiments of the present invention, the guide plate 6 is an arc-shaped plate structure, the curvature of which is consistent with the curvature of the outer wall of the roller body 3. This design allows the guide plate 6 to better fit the roller body 3, reduce gaps, optimize the blocking effect, and prevent the shot from flowing back and scattering during the discharge process, further improving the stability of shot recovery.

[0032] In some embodiments of the present invention, the roller body 3 is provided with multiple sets of guide grooves 4, which are distributed in a ring around the axis of the roller body 3. Each guide groove 4 extends along the axial direction of the roller body 3, and all sets of guide grooves 4 are connected to the storage space 5. The guide plate 6 is provided with multiple sets corresponding to the guide grooves 4, and they correspond one-to-one. By arranging multiple sets of guide grooves 4 and guide plates 6 according to the above structure, the collection efficiency of the roller body 3 for projectiles can be increased when it rotates.

[0033] See Figure 4In some embodiments of the present invention, the cleaning section 8 is disposed on the side wall of the guide plate 6 away from the guide groove 4. Since multiple sets of guide plates 6 can surround the roller body 3 when in the closed state, that is, can form a circumferential structure, the cleaning section 8 is disposed on the outer wall of the guide plate 6, which can make full use of the guide plate 6 in the closed state, effectively increase the distribution area of ​​the cleaning section 8, ensure the cleaning effect, and also increase the integration of the equipment.

[0034] See Figure 5 In some embodiments of the present invention, the guide groove 4 is a slanted straight groove or a slanted arc groove; its radial offset direction corresponds to the rotation direction of the roller 3. The slanted straight groove or slanted arc groove design can match the rotation direction of the roller, promoting smooth flow of the shot into the storage space. Simultaneously, rotational inertia can be used to prevent the shot from falling out again, ensuring the continuity and stability of shot movement during shot blasting.

[0035] See Figure 7 and Figure 8 In some embodiments of the present invention, a drive rod 10 is installed inside the storage space 5 of the roller body 3, which is driven to reciprocate along the axial direction of the roller body 3; the moving drive rod 10 can push the projectile located in the storage space 5 out of the discharge port 7.

[0036] An adapter 11 is installed on the roller body 3. The adapter 11 includes an "L"-shaped connecting rod 110, which is hinged to the roller body 3 in the middle. One end of the connecting rod 110 is a connecting end 12, and the other end is a driving end 13. The guide plate 6 has a groove 16, and the connecting end 12 is rotatably installed in the groove 16. The end of the driving rod 10 has a boss 14. When the driving rod moves, the boss 14 engages with the driving end 13 to drive the connecting rod to rotate, which in turn drives the guide plate 6 to rotate.

[0037] A torsion spring is installed at the hinge of the connecting rod 110 to drive it to return to its original position. When the drive rod 10 pushes the projectile out, the boss 14 releases its pressure on the adapter 11, the adapter 11 returns to its original position, and drives the guide plate 6 to close. The above structure can form an efficient working cooperation to achieve the working state of projectile discharge and guide plate 6 closure.

[0038] During operation, the drive rod, driven by an external power source (such as a cylinder), reciprocates along the axis of the roller. As the drive rod moves, the boss at its end gradually approaches and contacts the drive end of the adapter. The contact between the boss and the drive end forces the adapter 11 to rotate, which in turn drives the connecting end 12 to change the angle of the guide plate. The groove design on the guide plate allows the connecting end to rotate and move within the groove, thereby ensuring that the guide plate can smoothly switch its working state, such as from the open state to the closed state, or vice versa.

[0039] The rotation drive of roller 3 is provided by a separate power mechanism, which can be a motor connected to the end of the roller via gear transmission or belt transmission. When the equipment starts, the power mechanism drives the roller to rotate at a set speed, and the rotation direction of the roller needs to be adapted to the guide plate 6 and the guide groove 4. This rotation drive design, together with the angle switching mechanism of the guide plate, constitutes the core working system of the iron accessory grinding and polishing device, effectively improving the overall cleaning efficiency and automation level of the equipment.

[0040] In some embodiments of the present invention, two sets of rollers 3 are provided, and the high-pressure nozzles 2 are disposed between the two sets of rollers 3. This layout allows the high-pressure nozzles 2 to work effectively in conjunction with the rollers 3 on both sides, improving cleaning efficiency. At the same time, this structure makes the force more balanced, enhancing the stability of the equipment.

[0041] This invention also discloses a method for grinding and polishing iron accessories, comprising the following steps: The iron fittings are fed into the polishing equipment mentioned above, and the polishing equipment is used to propel high-speed shot onto the surface of the iron fittings for grinding and polishing. The high-pressure nozzle sprays high-pressure airflow into the grinding area, blowing away the shot and grinding debris that adhered to the surface of the iron attachments and fell into the processing area after grinding. The roller body is driven to rotate, and the bullets and debris raised by the airflow are guided by the guide plate on the outer wall and guided into the storage space inside the roller body for temporary storage. At the same time, the cleaning part on the surface of the roller body continuously contacts the surface of the iron accessories as it rotates, sweeping away the residual bullets and grinding impurities. Once a certain amount of shot has been collected in the roller body, it is discharged uniformly through the pre-set discharge port of the roller body. The shot is then screened to separate the reusable shot from the grinding waste debris. The qualified shot is sent back to the polishing equipment for reuse, thus completing the grinding and polishing process of the iron accessories.

[0042] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
