Description

Technical Field

[0001] The invention relates to the technical field of surface treatment equipment, in particular to an energy-saving metal material surface treatment sandblasting machine. Background Art

[0002] Sandblasting machine is a mechanical device that uses compressed air as power to spray abrasive particles onto the surface of the workpiece to clean or treat the surface of the workpiece. It can remove impurities such as oxide layer, dirt, paint, etc. on the surface of the workpiece, while improving the roughness of the surface of the workpiece, increasing adhesion, and preparing for subsequent painting, spraying or coating processes. The working principle of the sandblasting machine is to accelerate the abrasive particles through compressed air and spray them onto the surface of the workpiece to achieve the effect of cleaning and treatment. According to different application requirements, sandblasting machines can be divided into two categories: dry sandblasting machines and liquid sandblasting machines. Dry sandblasting machines can be further divided into suction type and pressure type. Sandblasting machines are widely used in many fields, including metal processing, automobile manufacturing, ship repair, construction, and aerospace. It is suitable for the surface treatment of various metal and non-metal workpieces, and can meet various needs such as rust removal, grinding, and roughening.

[0003] For some metal bushing accessories of automobiles, due to the influence of the external environment on their surfaces after a long time or storage, there will be impurities and pollutants such as oxidized rust layer and oil stains. If they are recycled and remanufactured, the first step is to treat their surfaces with a sandblasting machine to clean their surfaces, and then spray them and other remanufacturing processes. However, due to some oil stains on the surfaces of the metal accessories, when the surfaces are treated by a sandblasting machine, the oil stains on the surface can easily stick the used corundum into blocks, thereby causing the corundum to clog the sandblasting tube during subsequent recycling, affecting the normal processing operations of the subsequent sandblasting.

[0013] Working principle: When remanufacturing some recycled automobile axle sleeve accessories, the positioning drive mechanism is started first, and the staff first opens the upper box through the opening handle on the upper box. Then, after the upper box is opened, the staff will place the automobile axle sleeve to be processed vertically on the mounting seat on the top of the mesh plate, and at the same time, the lower sleeve, pressure plate and rubber ring seat on the rotating seat are inserted into the interior of the sleeve, thereby completing the first step of preparation for the sleeve before processing. After the first step of preparation for the sleeve is completed, the staff will rotate and reset the upper box on the lower box, so that the interior of the upper box and the lower box are in a closed state, and then the electric cylinder in the upper box The electric cylinder is started, and the rod body on it is pushed out after starting. The rod body of the electric cylinder drives the contact seat on it to move down synchronously while being pushed out. When the bottom of the contact seat contacts the top of the upper sleeve and the uppermost pressure plate, the contact seat continues to move down, and the contact seat continues to move down while squeezing the upper sleeve and the pressure plate, so that the spring in the upper sleeve contracts, and at the same time, the pressure plate also synchronously squeezes the rubber ring seat at the bottom to deform it, so that the deformed rubber squeezes the automobile sleeve, so that the sleeve is centrally positioned and fixed on the rotating seat, thereby completing the second step of preparation for the sleeve before processing. After completing the second step of transformation of the sleeve, the drive motor at the bottom of the mesh plate The drive motor is started, and the drive motor drives the rotating shaft thereon to rotate while starting. The rotating shaft of the drive motor drives the rotating seat on the mounting seat to rotate while rotating. The rotating seat drives the automobile shaft sleeve thereon and the contact seat therein to rotate synchronously while rotating. At the same time, the sandblasting gun on the upper box body is started, and the diamond sand is sprayed on the outer wall of the automobile shaft sleeve through the sandblasting gun, so as to complete the positioning of the automobile shaft sleeve and drive the sandblasting treatment; at the same time, the multiple dust reduction mechanisms are started, and while the positioning drive mechanism is sandblasting the automobile shaft sleeve, the high-power fan on the lower box body is started. After starting, the high-power fan draws the air inside the mounting box on the upper box body through the connecting pipe, so that A short negative pressure state is formed inside the installation box. At this time, as the sandblasting process proceeds, the dust generated by the sandblasting process inside the upper box enters the installation box through the drainage channel. First, when the air carrying dust passes through the water curtain sprayed by the water curtain spray, most of the dust carried in the air is filtered and absorbed by the water curtain. Then, the air carrying dust passes through the filter cotton plate on the installation frame for multiple filtering treatments on the dust it carries. Finally, the air after the secondary filtering treatment passes through the collection bag on the partition plate 2 when it is discharged, and the dust remaining in the air is finally collected by the collection bag, thereby completing the multiple dust reduction and purification treatments during the sandblasting process of the automobile shaft sleeve;At the same time, multiple noise reduction mechanisms are activated. When the staff places the automobile axle sleeve to be processed in the upper box, the staff resets and closes the upper box. At this time, the metal convex strip on the upper box also enters the groove on the lower box simultaneously. The metal convex strip entering the groove is affected by the magnetic coating, so that the metal convex strip squeezes the silicone layer in the groove to deform. The deformed silicone layer fills and seals the gap between the upper box and the lower box after sealing. At the same time, when the automobile axle sleeve is sandblasted, the The noise is firstly treated with the sound-absorbing cotton layer inside the box body for preliminary noise reduction treatment, and then the noise after the noise reduction treatment is secondary absorbed and reduced by the honeycomb noise reduction plate, and finally the final absorption and noise reduction treatment is carried out by the sound-absorbing cotton layer on the outside, thereby completing the multiple noise reduction treatments on the noise generated during the sandblasting process; then the sorting circulation mechanism is started, and during the sandblasting process of the automobile shaft sleeve, the diamond abrasive material used in the sandblasting process falls through the mesh holes on the mesh plate, and then passes through the inclined guide seat 1 and the inclined guide seat 3 in the lower box body during the falling process. The guide of the inclined guide seat 1 causes the diamond sand to fall from the gap between the two. At the same time, the airflow separator at the bottom of the inclined guide seat 1 is started. If the diamond sand material after use is contaminated by oil and sticks into blocks, the airflow generated by the airflow separator cannot blow it. Therefore, the diamond sand raw material contaminated by oil and sticks into blocks falls on the side of the inclined guide seat 2 close to the airflow separator for collection. The diamond sand that is not contaminated by oil is lighter in weight, so when it passes through the airflow generated by the airflow separator, it is blown and falls on the sieve plate through the guidance of the inclined guide seat 2. At the same time, the vibrator on the sub-screen plate is started, and the vibrator vibrates after starting, thereby promoting the use of the corundum material on the sub-screen plate to fall, and then the qualified corundum material after screening falls to the bottom of the sub-screen plate. When it is used again, it can be pumped and transported by the suction device on the lower box body for reuse. After a certain number of corundum blocks contaminated by oil are collected, the staff can open the door on the lower box body to centrally process them, thereby completing the sorting and recycling of corundum materials. ;

[0014] The present invention provides an energy-saving metal material surface treatment sandblasting machine, which has the following beneficial effects: 1. The present invention adds and sets a positioning drive mechanism. First, the mechanism can effectively solve the problem of fixing the shaft sleeve accessories during sandblasting. Accurate positioning ensures that the accessories remain motionless during the treatment process, greatly improving the stability and accuracy of the sandblasting treatment. Then, after the fixing is completed, it is driven to rotate immediately. In conjunction with the sandblasting gun, the shaft sleeve can be treated with all-round surface treatment without dead angles, so that the sandblasting effect of the shaft sleeve surface is uniform and consistent, and its surface quality and finish are significantly improved. It not only enhances the wear resistance of the shaft sleeve, but also provides reliable guarantee for subsequent remanufacturing treatment, greatly improving the overall process level and efficiency of automobile shaft sleeve production.

[0015] 2. The present invention realizes efficient treatment of dust generated by sandblasting by adding and setting multiple dust removal mechanisms. During the treatment process, the multiple dust removal mechanisms of the mechanism work together to quickly capture large particles of dust in the air to prevent them from floating around, and then deeply adsorb and filter the fine dust, greatly reducing the dust concentration in the workshop. This treatment method not only effectively improves the working environment of the workshop and reduces the potential harm of dust to the health of operators, but also prevents dust from adhering to the surface of the sleeve to affect the treatment effect and product quality, providing a cleaner, safer and more efficient process guarantee for the production of automobile sleeves.

[0016] 3. The present invention can effectively intervene in various noise sources generated by sandblasting by adding and setting multiple noise reduction mechanisms. First, the mechanism can absorb the high-frequency noise generated by the operation of the equipment, greatly reducing its sharp and harsh feeling, and at the same time block and reduce the low-frequency noise generated by the sandblasting impact, so that the overall noise level is significantly reduced. This treatment method greatly improves the acoustic environment of the workshop, reduces the damage of noise to the hearing of operators, reduces work fatigue and misoperation risks caused by noise, creates a more comfortable and safe working atmosphere, and effectively improves the level of occupational health protection in the production process of automobile bushings.

[0017] 4. The present invention adds and sets a sorting circulation mechanism. During the sandblasting operation, the mechanism performs multi-step fine sorting of corundum, accurately identifies and removes sticky blocks formed by oil pollution. This measure effectively ensures the stability and uniformity of the sandblasting process, avoids poor sandblasting effect caused by sticky blocks, and this treatment method not only reduces the amount of corundum discarded due to raw material pollution and reduces production costs, but also improves the recycling rate of corundum, so that resources can be fully utilized. At the same time, a stable supply of raw materials also helps to improve the quality and efficiency of automobile shaft sleeve surface treatment, and has a good energy-saving effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please see attached Figure 1 - Attachment Figure 2The embodiment of the present invention provides an energy-saving metal material surface treatment sandblasting machine, including an upper box body 1, which is used as the basic component of the overall device for assembling and carrying a positioning drive mechanism and a multiple dust reduction mechanism and their lower structural parts; a lower box body 6, which is rotatably connected to one side of the bottom of the upper box body 1, and is used for assembling and carrying multiple noise reduction mechanisms and a sorting circulation mechanism and their lower structural parts; an air compressor 2 is arranged in the middle of the top of the upper box body 1, an observation window 3 is arranged in the middle of the front side of the upper box body 1, and operation panels 7 are arranged on both sides of the middle of the front end of the upper box body 1, and opening handles 4 are fixedly connected to both sides of the bottom end of the front side of the upper box body 1.

[0022] Please see attached Figure 4 - Attachment Figure 5 , a positioning drive mechanism, which is arranged in the upper box body 1, and is used to position the automobile shaft sleeve parts to be processed and drive the sandblasting process; The positioning drive mechanism includes a mesh plate 28, the mesh plate 28 is fixedly connected to the middle and upper part of the inner wall of the lower box body 6, the mounting seat 30 is fixedly connected to the middle part of the top of the mesh plate 28, the middle part of the mounting seat 30 is rotatably connected to the rotating seat 32, the middle part of the rotating seat 32 is fixedly connected to the lower sleeve 29, the inner middle and upper part of the lower sleeve 29 is slidably connected to the upper sleeve 34, a spring 43 is arranged inside the upper sleeve 34, and a plurality of pressure plates 14 and rubber ring seats 33 are staggered on the outer wall of the upper sleeve 34.

[0023] When the positioning drive mechanism is started, the staff first opens the upper box body 1 through the opening handle 4 on the upper box body 1. Then, after the upper box body 1 is opened, the staff vertically places the automobile axle sleeve to be processed on the mounting seat 30 on the top of the mesh plate 28, and also makes the lower sleeve 29, the pressure plate 14 and the rubber ring seat 33 on the rotating seat 32 inserted into the interior of the axle sleeve, thereby completing the first step of preparation of the axle sleeve before processing.

[0024] The positioning drive mechanism also includes a drive motor 31. The drive motor 31 is arranged in the middle of the bottom end of the mesh plate 28, and the output end of the drive motor 31 passes through the mounting seat 30 and is connected to the middle of the rotating seat 32. A protective cover 24 is arranged at the bottom end of the mesh plate 28, and an electric cylinder 16 is arranged in the middle of the top end of the inner wall of the upper box body 1. The bottom end of the rod body of the electric cylinder 16 is rotatably connected to the contact seat 17, and a sandblasting gun 12 is arranged in the middle and lower parts of both sides of the inner wall of the upper box body 1.

[0025] After the first step of preparation for the sleeve is completed, the staff rotates and resets the upper box body 1 on the lower box body 6, so that the interior of the upper box body 1 and the lower box body 6 are in a closed state, and then the electric cylinder 16 in the upper box body 1 is started. After the electric cylinder 16 is started, the rod body on it is pushed out, and the rod body of the electric cylinder 16 drives the contact seat 17 on it to move downward synchronously while pushing out. When the bottom of the contact seat 17 contacts the top of the upper sleeve 34 and the uppermost pressure plate 14, the contact seat 17 continues to move downward, and the contact seat 17 continues to move downward while squeezing the upper sleeve 34 and the pressure plate 14, so that the spring 43 in the upper sleeve 34 contracts, and at the same time, the pressure plate 14 also synchronously squeezes the rubber ring seat 33 at its bottom to deform it, so that the deformed rubber squeezes the automobile sleeve, so that the sleeve is centered and fixed on the rotating seat 32, thereby completing the second step of preparation for the sleeve before processing.

[0026] After completing the second step of transformation of the sleeve, the drive motor 31 at the bottom of the mesh plate 28 is started. When the drive motor 31 is started, it drives the rotating shaft thereon to rotate. When the rotating shaft of the drive motor 31 rotates, it drives the rotating seat 32 on the mounting seat 30 to rotate. When the rotating seat 32 rotates, it drives the automobile sleeve thereon and the contact seat 17 therein to rotate synchronously. At the same time, the sandblasting gun 12 on the upper box body 1 is started, and the diamond sand is sprayed onto the outer wall of the automobile sleeve through the sandblasting gun 12, thereby completing the positioning of the automobile sleeve and driving the sandblasting process.

[0027] Please see attached Figure 7 , a multiple dust reduction mechanism, which is arranged at the rear side of the upper box body 1, and is used for multiple dust reduction and adsorption purification treatment of dust generated during the sandblasting process of the automobile shaft sleeve accessories by the positioning drive mechanism; The multiple dust reduction mechanisms include an installation box 11, which is arranged in the middle of the rear side of the upper box body 1, a drainage channel 13 is arranged on one side of the rear end of the inner wall of the upper box body 1, and the interior of the drainage channel 13 is connected with the interior of the installation box 11, and a high-power fan 9 is arranged in the middle of the rear side of the lower box body 6, and the air inlet of the high-power fan 9 is connected with the bottom side of the upper box body 1 through a connecting pipe.

[0028] When the multiple dust reduction mechanisms are started, while the positioning drive mechanism is sandblasting the automobile axle sleeve, the high-power fan 9 on the lower box body 6 is started. After starting, the high-power fan 9 draws the air inside the installation box 11 on the upper box body 1 through the connecting pipe, thereby forming a short negative pressure state inside the installation box 11. At this time, as the sandblasting process proceeds, the dust generated by the sandblasting process inside the upper box body 1 enters the installation box 11 through the drainage channel 13.

[0029] The multiple dust reduction mechanisms also include a partition plate 35, a partition plate 35 is fixedly connected to one side in the middle of the bottom end of the inner wall of the installation box 11, a water curtain spray 36 is arranged on one side of the top end of the inner wall of the partition plate 35, a circulation pump 10 is arranged in the middle of one side of the outer wall of the installation box 11, and the liquid inlet of the circulation pump 10 is connected to one side of the bottom end of the inside of the installation box 11 through a connecting pipe, and the liquid outlet of the circulation pump 10 is connected to the liquid inlet of the water curtain spray 36 through a connecting pipe, a plurality of installation frames 40 are fixedly connected at equal intervals to the middle of the inner side of the installation box 11, and filter cotton plates 37 are arranged on the inner sides of the installation frames 40, a partition plate 2 39 is fixedly connected to the side of the inside of the installation box 11 away from the installation frame 40, and a plurality of collection bags 38 are arranged at equal intervals on the partition plate 2 39.

[0030] First, when the dust-carrying air passes through the water curtain sprayed by the water curtain spray 36, most of the dust carried in the air is filtered and absorbed by the water curtain, and then the dust-carrying air passes through the filter cotton plate 37 on the mounting frame 40 to perform multiple filtering treatments on the dust it carries. Finally, the air after the secondary filtering treatment passes through the collecting bag 38 on the partition plate 2 39 when it is discharged, and the dust remaining in the air is finally collected by the collecting bag 38, thereby completing the multiple dust reduction and purification treatments during the sandblasting process of the automobile shaft sleeve.

[0031] Please see attached Figure 4 and attached Figure 8 , multiple noise reduction mechanisms, which are arranged in the lower box body 6, are used for multiple absorption and noise reduction of the noise generated during the sandblasting process of the automobile shaft sleeve accessories by the positioning drive mechanism; The multiple noise reduction mechanisms include a metal convex strip 15, which is fixedly connected to the middle of the bottom end of the upper box body 1, and a magnetic coating 27 is provided on the outer wall of the metal convex strip 15. A groove 18 is opened in the middle of the top end of the lower box body 6, and a silicone layer 26 is provided on the inner wall of the groove 18. A honeycomb noise reduction plate 41 is provided in the middle of the inner side of the upper box body 1 and the lower box body 6, and sound-absorbing cotton layers 42 are provided on both sides of the honeycomb noise reduction plate 41.

[0032] When the multiple noise reduction mechanisms are started, the staff places the automobile axle sleeve to be processed into the upper box body 1, and the staff resets and closes the upper box body 1. At this time, the metal convex strip 15 on the upper box body 1 also enters the groove 18 on the lower box body 6 simultaneously. The metal convex strip 15 entering the groove 18 is affected by the magnetic coating 27, so that the metal convex strip 15 squeezes the silicone layer 26 in the groove 18 to deform. The deformed silicone layer 26 fills and seals the gap that exists after the upper box body 1 and the lower box body 6 are closed. At the same time, when the automobile axle sleeve is sandblasted, the noise generated by it is first subjected to preliminary noise reduction treatment by the sound-absorbing cotton layer 42 on the inside of the box body, and then the noise after the noise reduction treatment is completed is subjected to secondary absorption and noise reduction by the honeycomb noise reduction plate 41, and finally the final absorption and noise reduction treatment is performed by the outer sound-absorbing cotton layer 42, thereby completing the multiple noise reduction treatment of the noise generated during the sandblasting process.

[0033] Please see attached Figure 4 The sorting and recycling mechanism is arranged at the inner lower part of the lower box body 6 and is used for sorting and recycling the diamond abrasive raw materials used in the sandblasting process of automobile shaft sleeve accessories.

[0034] The sorting circulation mechanism includes an inclined guide seat 19, an inclined guide seat 19 is arranged on one side of the middle and upper part of the inner wall of the lower box body 6, an inclined guide seat 3 25 is arranged on the side of the inner wall of the lower box body 6 away from the inclined guide seat 19, an airflow sorter 20 is arranged at the bottom of the inclined guide seat 19, an inclined guide seat 21 is fixedly connected to one side of the middle part of the bottom end of the inner side of the lower box body 6, a screening plate 23 is fixedly connected to the middle and upper part of one side of the inclined guide seat 21, a vibrator 22 is arranged at the middle part of the bottom end of the screening plate 23, an opening door 5 is arranged at the bottom of the front end of the lower box body 6, and a suction device 8 is arranged at the middle part of the bottom end of the rear side of the lower box body 6.

[0035] When the sorting circulation mechanism is started, during the sandblasting process of the automobile axle sleeve, the corundum material used in the sandblasting process falls through the mesh holes on the mesh plate 28, and then falls from the gap between the inclined guide seat 19 and the inclined guide seat 3 25 in the lower box 6 during the falling process, and at the same time, the airflow sorter 20 at the bottom of the inclined guide seat 19 is started.

[0036] If the used corundum material is contaminated by oil and sticks together, the airflow generated by the airflow separator 20 cannot blow it away, so the corundum raw material contaminated by oil and sticks together falls to the side of the inclined guide seat 21 close to the airflow separator 20 for collection.

[0037] Since the corundum that is not contaminated by oil is lighter in weight, it is blown when it passes through the airflow generated by the airflow sorter 20 and falls onto the sub-screen plate 23 through the guidance of the inclined guide seat 21. At the same time, the vibrator 22 on the sub-screen plate 23 is started. After starting, the vibrator 22 vibrates, thereby promoting the used corundum material on the sub-screen plate 23 to fall. Then, the qualified corundum material after screening falls to the bottom of the sub-screen plate 23. When it is used again, it can be pumped and transported by the suction device 8 on the lower box 6 for reuse. After a certain number of corundum sticking blocks contaminated by oil are collected, the staff can centrally process them by opening the opening door 5 on the lower box 6, thereby completing the sorting and recycling of the corundum material.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
