Description

Technical Field

[0001] This invention relates to the field of shot blasting machine accessories technology, specifically to an alloy wear-resistant shot blasting machine blade. Background Technology

[0002] Shot blasting machines are primarily used for metal surface treatment, strengthening, and finishing. Their working principle involves feeding steel shot into a high-speed rotating impeller inside the machine. Centrifugal force propels the high-speed steel shot to impact the product surface, achieving the purpose of cleaning or strengthening. The impeller blades are the parts that directly contact the steel shot during blasting. The high-speed friction with the steel shot makes these blades highly susceptible to damage, making their wear resistance a key indicator. Failure of shot blasting machine blades is the result of both wear and fatigue. During the operation of the shot blasting machine blades, they are subjected to the stress of the shot cycle. The blades first undergo basic structural deformation, and the surface matrix structure experiences compressive flow, starting from the stress concentration point on the blade.

[0003] To overcome wear, existing shot blasting machine blades use more wear-resistant alloy materials, thicken the blades to extend their service life after wear, or continuously replace the wear-resistant materials to replace the wear of the blades themselves. However, each replacement of the wear-resistant material results in material waste, and it is difficult to solve the problem of reusing wear-resistant materials with existing technology. Therefore, we propose an alloy wear-resistant shot blasting machine blade. Summary of the Invention

A cone block is fixed to the top of the push spring, and the cone top of the cone block engages with the V-shaped opening.

[0011] Preferably, a second sliding groove, a boss, a serrated groove, and a second adjusting mechanism are used instead of a slanted groove, a bayonet, a V-shaped opening, and a first adjusting mechanism. The second sliding groove is opened on the side surface of the wear-resistant projectile close to the groove, and the second sliding groove is symmetrically distributed about the center line of the wear-resistant projectile. The inner wall of the second sliding groove is provided with a boss distributed in a stepped manner, and the surface of the boss is provided with a serrated groove.

[0012] The blade substrate is provided with a second adjustment mechanism on both sides of the transverse direction, which allows for adjustment of the thickness of the wear-resistant projectile extending into the embedded groove.

[0014] Preferably, a compression block B is sleeved on the outer side of the threaded adjusting rod, and the compression block B is connected to the threaded adjusting rod through a threaded hole in the middle. A serrated protrusion is fixed at the bottom of the compression block B.

[0015] Preferably, the wear-resistant projectile has a triangular wavy pre-reserved slot inside, and a filler layer for energy absorption and buffering is provided inside the pre-reserved slot, with a support layer inserted at the tip of the pre-reserved slot.

[0016] Preferably, the sidewall of the material distribution section of the blade substrate is symmetrically provided with limiting grooves, and a first connecting post and a second connecting post are respectively provided on the side of the blade substrate near the material distribution section.

[0018] Beneficial effects: Compared with the prior art, the advantages of the alloy wear-resistant shot blasting machine blades of the present invention are as follows:

[0019] 1. Rotating the screw along the longitudinal position of the blade drives the extrusion block A to move step by step along the equally spaced inclined grooves. This allows for continuous adjustment of the thickness of the wear-resistant propellant extending outward along the embedded groove, reducing the frequency of replacement. Rotating the threaded adjustment rod along the transverse position of the blade drives the extrusion block B to move upward along the stepped protrusions, allowing for the extrusion of the wear-resistant propellant out of the embedded groove in stages. This facilitates the adjustment of the position of the worn wear-resistant propellant, reducing the frequency of replacement. Furthermore, by setting up replaceable and retractable adjustable alloy wear-resistant components, the high wear resistance and reusability of the shot blasting machine blades can be achieved.

[0020] 2. Insert the support layer of high-chromium cast iron rod into the triangular wavy pre-reserved slot, so that the aluminum liquid fully fills the pre-reserved slot and supports the pre-reserved slot to prevent deformation. After the aluminum liquid cools and solidifies, use a welding machine to weld along the edge of the pre-reserved groove of the wear-resistant projectile to prevent the filler layer from leaking outward when the wear-resistant projectile is impacted by shot blasting. The filler layer made of foamed aluminum can absorb energy and buffer, so that the wear-resistant projectile can reduce the impact when it is impacted, which can improve the service life of the shot blasting machine blades.

[0021] 3. By connecting the blade base with the first and second connecting columns as needed, the blade of the shot blasting machine can be lengthened, thereby reducing the shot blasting volume. Conversely, by removing the first and second connecting columns on one side of the blade base and installing the blade base at an equal angle on the mounting plate, the length of the blade base can be reduced, allowing the shot blasting machine to increase the shot blasting volume during shot blasting. This allows the shot blasting machine blade to adjust the shot blasting volume according to the actual shot blasting processing needs. Attached Figure Description

[0039] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 12 The alloy wear-resistant shot blasting machine blade of the present invention includes a blade base 1, reinforcing ribs 2, and an embedded groove 3. Limiting seats 101 are integrally formed on both sides of the blade base 1. The blade base 1 adopts an arc-shaped structure. The front arc surface of the blade base 1 is the blasting working part, and the rear arc surface of the blade base 1 is the material distribution working part. A reinforcing rib 2 for blade pressure resistance is provided in the middle of the outer wall of the blade base 1, ensuring that the shot blasting machine blade has a central pressure resistance effect during rotating shot blasting, and preventing damage to the blade during shot blasting. Excessive pressure caused deformation in the middle section. An embedding groove 3 is laterally opened on the inner side of the projectile working section of the blade base 1. A rotating groove 301 is opened on the front edge of the embedding groove 3 near the material distribution working section. A card seat 302 is opened on the front edge of the embedding groove 3 near the projectile working section. The card seat 302 is L-shaped. Tensioning springs 303 are installed at equal intervals in the middle of the inner wall of the embedding groove 3. A plug plate 304 is welded to one end of the tensioning spring 303. The length of the plug plate 304 is less than the width of the wear-resistant projectile 5.

[0041] A wear-resistant projectile 5 is inserted into the interior of the embedded groove 3. The wear-resistant projectile 5 is connected to the rotating groove 301 via a rotating column 501 on one side. The wear-resistant projectile 5 is connected to the insert plate 304 via a groove 502 on one side. The groove 502 has a "C" shaped cross section. A protrusion 503 is fixed on the side of the wear-resistant projectile 5 away from the rotating column 501, and the protrusion 503 is mated in the card seat 302. The wear-resistant projectile 5 forms a rotating structure between the rotating column 501 and the rotating groove 301. The insert plate 304 and the groove 502 on the surface of the wear-resistant projectile 5 are slidably connected. Side blocks 507 are integrally formed on both sides of the wear-resistant projectile 5.

[0042] In specific implementation, the wear-resistant projectile 5 is inserted into the embedding groove 3 on the concave side of the blade base 1, and the rotating column 501 on one side and the protrusion 503 on the other side of the wear-resistant projectile 5 are respectively inserted into the rotating groove 301 and the card seat 302, so that the wear-resistant projectile 5 made of high chromium cast iron can be quickly assembled into the blasting working area of ​​the blade base 1. When multiple blade bases 1 distributed at equal angles are assembled around the center hole of the matching mounting plate, the rotating shot blasting machine blades will distribute steel shot along the rear side of the blade base 1 and perform high-speed centrifugal shot blasting along the wear-resistant projectile 5 of the front side of the shot blasting working area of ​​the blade base 1. The thickened wear-resistant projectile 5 can improve the wear resistance and practicality of the shot blasting machine blades, and the sliding insertion and removal along the side of the embedding groove 3 can facilitate the replacement of the wear-resistant projectile 5.

[0043] Meanwhile, the insert plate 304 welded to one side of the tensioning spring 303 is slidably inserted into the "C"-shaped groove 502 on the surface of the wear-resistant projectile 5, so that the wear-resistant projectile 5 can be tightened and fitted into the embedding groove 3. By setting side stops 507 on both sides of the wear-resistant projectile 5, the side stops 507 are flush with the outer side of the limiting seat 101. When the shot blasting machine blade is assembled, the limiting seats 101 on both sides of the blade base 1 are connected to the reserved groove of the matching mounting plate, so that the wear-resistant projectile 5 abuts against the reserved groove of the matching mounting plate through the side stops 507 on both sides, thereby preventing the wear-resistant projectile 5 from wobbling left and right after installation.

[0044] Please see Figure 8 , Figure 9 , Figure 13 and Figure 14 The wear-resistant projectile 5 has a triangular wavy reserved slot inside, and a filler layer 7 for energy absorption and buffering is provided in the reserved slot. A support layer 8 is inserted into the tip of the reserved slot. The filler layer 7 is made of aluminum foam, and the support layer 8 is made of rod-shaped high-chromium cast iron.

[0045] In practice, aluminum blocks are melted in a melting furnace, and the molten aluminum is then foamed in a foaming furnace. The foamed aluminum is then poured into the triangular wavy pre-reserved slot inside the wear-resistant projectile 5 for casting. During casting, a support layer 8 of rod-shaped high-chromium cast iron is inserted into the triangular wavy pre-reserved slot to ensure that the aluminum fully fills the slot and supports it to prevent deformation. After the aluminum cools and solidifies, a welding machine is used to weld along the edge of the pre-reserved slot of the wear-resistant projectile 5 to prevent the filler layer 7 from leaking out when the wear-resistant projectile 5 is impacted by shot blasting. The filler layer 7, made of foamed aluminum, can absorb energy and buffer, allowing the wear-resistant projectile 5 to reduce impact when subjected to impact, thus improving the service life of the shot blasting machine blades.

[0046] Please see Figure 3 , Figure 4 , Figure 5 and Figure 7 The side wall of the material distribution section of the blade base 1 is symmetrically provided with limiting grooves 102. On the side of the blade base 1 near the material distribution section, a first connecting post 9 and a second connecting post 901 are respectively provided. The end of the first connecting post 9 is provided with a socket 902, and the end of the second connecting post 901 is provided with a magnetic insert 903.

[0047] In practice, the first connecting post 9 and the second connecting post 901 are connected by the attraction of the socket 902 and the magnetic plug 903, respectively, so that the first connecting post 9 and the second connecting post 901 have a locking connection effect.

[0048] Please see Figure 3 , Figure 5 and Figure 7 An arc-shaped block 904 is welded to one end of the first connecting column 9 and the second connecting column 901 away from each other. A barbed hook block 905 is provided on one side of the arc-shaped block 904, and the arc-shaped block 904 is engaged with the limiting groove 102. The barbed hook block 905 is used to engage with the central hole wall of the shot blasting machine mounting plate. The thickness of the barbed hook block 905 is the same as the thickness of the limiting seat 101.

[0049] In practice, the arc-shaped block 904 and the barbed clip 905 are placed on the mounting plate of the shot blasting machine blade. Then, the limiting groove 102 of the blade base 1 is clipped onto the arc-shaped block 904. Then, the first connecting post 9 and the second connecting post 901 are magnetically engaged and plugged in through the socket 902 and the magnetic plug 903, respectively. When the two sets of mounting plates are clamped, the engagement between the mounting plate and the barbed clip 905 and the engagement between the arc-shaped block 904 and the limiting groove 102 ensures that the blade base 1 can be prevented from swinging off when rotating at high speed. If necessary, the blade base 1 can be combined and connected with the first connecting post 9 and the second connecting post 901 to lengthen the shot blasting machine blade, thereby reducing the shot blasting volume.

[0050] Conversely, by removing the No. 1 connecting post 9 and the No. 2 connecting post 901 on one side of the blade base 1, and installing the blade base 1 at an equal angle on the mounting plate, the length of the blade base 1 is reduced, allowing the shot blasting machine to increase the shot blasting volume. Furthermore, after removing the No. 1 connecting post 9, the No. 2 connecting post 901, the socket 902, the magnetic rod 903, the arc block 904, and the barbed clip 905, since the blade base 1 is arc-shaped and is installed at an equal angle on the mounting plate, the centrifugally rotating blade base 1 will abut against the reserved groove on the mounting plate through its outer arc surface, thus preventing the blade base 1 from flying off. Example 1

[0051] Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 10 and Figure 11 The wear-resistant projectile 5 has equally spaced inclined grooves 504 on one side surface near the groove 502. The bottom of the inclined groove 504 has a bayonet 505. The outer wall of the wear-resistant projectile 5 is an arc structure. The equally spaced inclined grooves 504 on the outer wall of the wear-resistant projectile 5 are arranged with increasing height from left to right. The wear-resistant projectile 5 is made of high-chromium cast iron. The upper inner wall of the bayonet 505 has a V-shaped opening 506. The inner cavity of the blade base 1 near the inclined groove 504 is provided with a first adjustment mechanism 4 that can adjust the thickness of the wear-resistant projectile 5 extending out of the embedded groove 3.

[0052] The first adjustment mechanism 4 consists of a first slide groove 401, a screw rod 402, a guide groove 403, an extrusion block A 404, a guide plate 405, a toothed block 406, a push spring 407, and a cone block 408. The first slide groove 401 is symmetrically opened in the upper cavity wall of the embedded groove 3. The screw rod 402 is connected to the inside of the first slide groove 401 through a bearing. The operating end of the screw rod 402 is set in the reserved groove on the outer edge of the front part of the blade base 1.

[0053] The inner wall of the first chute 401 is symmetrically provided with guide grooves 403 on both sides. An extrusion block A404 is inserted into the inside of the first chute 401. The guide plates 405 on both sides of the extrusion block A404 are slidably connected to the guide grooves 403. The top of the extrusion block A404 is fixed with a toothed block 406 that meshes with the spiral rod 402. The lower side wall of the extrusion block A404 abuts against the inclined groove 504. The lower edge of the extrusion block A404 is provided with a flange that connects to the bayonet 505. A push spring 407 is connected in the reserved groove inside the flange. A cone block 408 is fixed to the top of the push spring 407. The cone top of the cone block 408 is engaged with the V-shaped opening 506.

[0054] In practice, when the shot blasting machine uses the blade substrate 1 to perform shot blasting, the steel shot will cause extrusion wear against the wear-resistant propellant 5 on the inner side of the blade substrate 1. By periodically checking the thickness of the wear-resistant propellant 5 in the insertion groove 3, and rotating the screw rod 402 along the first slide groove 401, the screw rod 402 will mesh with the toothed block 406 on the top of the extrusion block A404 during rotation. This causes the toothed block 406 to drive the guide plates 405 on both sides of the extrusion block A404 to slide along the guide groove 403. As the extrusion block A404 moves step by step along the equally spaced inclined grooves 504, the extrusion block A404 will gradually move. The inclined groove 504 of the wear-resistant projectile 5 is pushed, so that the wear-resistant projectile 5 rotates around the rotating groove 301 through the rotating column 501, which facilitates the discharge of the wear-resistant projectile 5. When the extrusion block A404 corresponds to the inclined groove 504 at other positions, a gap will be generated between the extrusion block A404 and the inclined groove 504 at other positions. When the tightening spring 303 pulls the insert plate 304 to retract inward, the traction action of the tightening spring 303 can cause the wear-resistant projectile 5 to generate a slight reverse deflection inward on the extrusion block A404, so that the bottom of the extrusion block A404 is in contact with the inclined groove 504 at other positions again.

[0055] After completing the above operations, by rotating the screw rod 402 in the opposite direction, the toothed block 406 and the guide plate 405 move a small distance in the opposite direction, so that the flange at the bottom of the extrusion block A404 is locked in the bayonet 505, and the push spring 407 inside the flange squeezes the cone block 408 in the V-shaped opening 506, so that the connection between the extrusion block A404 and the bayonet 505 has a stable effect. Each time the docking position of the extrusion block A404 and the inclined groove 504 is adjusted, the thickness of the wear-resistant projectile 5 extending outward along the embedded groove 3 can be continuously adjusted, which can adapt to the continuous wear of the wear-resistant projectile 5 and reduce the number of times the wear-resistant projectile 5 is replaced. During adjustment, the operating end of the screw rod 402 is located at the front edge of the blade base 1. The wear-resistant projectile 5 can be adjusted when the shot blaster is removed and the mounting plate assembly is not removed.

[0056] The wear-resistant projectile 5 is supported by two symmetrically distributed extrusion blocks A404. When the blade substrate 1 is centrifugally rotated and shot blasted, the wear-resistant projectile 5 can be subjected to pressure. It should be noted that when installing the wear-resistant projectile 5, the inclined groove 504 on the wear-resistant projectile 5 needs to be aligned with the extrusion block A404 to complete the positioning and assembly. Example 2

[0057] Please see Figures 12-16 The second chute 508 is opened on the side surface of the wear-resistant projectile 5 near the groove 502, and the second chute 508 is symmetrically distributed about the center line of the wear-resistant projectile 5. The inner wall of the second chute 508 is provided with a stepped protrusion 509, and the surface of the protrusion 509 is provided with a serrated groove 510.

[0058] The blade base 1 is provided with two adjustable adjustment mechanisms 6 on both sides of the transverse side, which allow the adjustable wear-resistant projectiles 5 to extend out of the embedded grooves 3 to adjust the thickness.

[0059] The second adjustment mechanism 6 consists of a moving cavity 601, a threaded adjustment rod 602, a pressing block B603, and a serrated protrusion 604. The moving cavity 601 is symmetrically opened on both sides of the blade base 1. The threaded adjustment rod 602 is connected to the inside of the moving cavity 601 through a bearing. The operating end of the threaded adjustment rod 602 is set in the reserved groove inside the limit seat 101.

[0060] A pressing block B603 is sleeved on the outer side of the threaded adjusting rod 602, and the pressing block B603 is connected to the threaded adjusting rod 602 through the threaded hole in the middle. A serrated protrusion 604 is fixed at the bottom of the pressing block B603. An inclined pressing part is provided on the inclined side of the pressing block B603 near the boss 509. The size of the serrated protrusion 604 matches the size of the serrated groove 510, and the serrated groove 510 and the serrated protrusion 604 are engaged.

[0061] In specific implementation, by rotating the operating end of the threaded adjusting rod 602 forward along the lateral side of the limiting seat 101, the threaded adjusting rod 602 rotates and generates threaded transmission with the extrusion block B603 in the moving cavity 601. This facilitates pushing the extrusion block B603 along the second slide groove 508, causing the inclined extrusion part on one side of the bottom of the extrusion block B603 to extrude the inclined edge of the boss 509, so that the wear-resistant projectile 5 rotates around the rotating column 501. By continuously rotating the threaded adjusting rod 602 forward, the extrusion block B603 can be driven to move upward along the stepped boss 509, thereby extruding the wear-resistant projectile 5 in stages and leading it out of the embedded groove 3. This facilitates the adjustment of the position of the worn wear-resistant projectile 5 and reduces the number of replacements.

[0062] When the serrated protrusion 604 at the bottom of the extrusion block B603 engages with the serrated groove 510 on the surface of the boss 509, the extrusion block B603 can be restrained, and the reverse rotation of the threaded adjusting rod 602 can prevent the wear-resistant projectile 5 from retracting into the embedded groove 3. By setting the second adjusting mechanism 6 into two sets, it is convenient to provide stable and balanced support for both sides of the wear-resistant projectile 5. Furthermore, the second adjusting mechanism 6 adopts the transverse rotation operation of the threaded adjusting rod 602, and the adjustment operation of the wear-resistant projectile 5 can be performed without the obstruction of the mounting plate assembly.

[0063] In summary, by inserting the wear-resistant propellant 5 into the recessed groove 3 on the inner side of the blade base 1, the wear-resistant propellant 5, made of high-chromium cast iron, can be assembled in the blasting working area of ​​the blade base 1. Conversely, the wear-resistant propellant 5 can also be disassembled and replaced. Therefore, the replacement wear-resistant propellant 5 is provided, which makes it convenient to replace the wear-prone parts of the shot blasting machine blade with the wear-resistant propellant 5, which facilitates the long-term use of the shot blasting machine blade. Furthermore, by adjusting the thickness of the wear-resistant propellant 5 extending out of the recessed groove 3, the number of times the wear-resistant propellant 5 needs to be replaced can be reduced.
