Description

Technical Field

[0001] The invention relates to the technical field of sandblasting machines, and mainly relates to a sandblasting device used for surface treatment of a crystallizer copper tube. Background Art

[0002] Sandblasting technology is a process of cleaning and roughening the surface of a substrate by the impact of high-speed sand flow. Sandblasting technology generally uses compressed air as a power source to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, Hainan sand, etc.) at high speed onto the surface of the workpiece to be processed. Due to the impact and cutting effect of the sand material on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating.

[0003] Based on the use of sandblasting technology, sandblasting machines were manufactured. Sandblasting machines are widely used. They are generally powered by compressed air. Sand is fed into the sand conveying pipe and ejected through the nozzle to the surface of the workpiece being processed, so that the high-speed moving sand particles wash the surface of the workpiece to improve the surface quality of the workpiece. There are various types and specifications of sandblasting machines. When processing the crystallizer copper tube, the common sandblasting machine cannot perform all-round sandblasting on the surface of the crystallizer copper tube. Since the crystallizer copper tube is generally directly fixed in the sandblasting machine through the clamping tool, the sand sprayed cannot be effectively sprayed on the bottom surface of the crystallizer copper tube. When sandblasting, it is generally necessary to sandblast the remaining surfaces of the crystallizer copper tube first, and then remove the crystallizer copper tube and turn it over and clamp it again, and sandblast its untreated bottom surface. This is not only troublesome to operate, but also makes the processing time of a workpiece longer, time-consuming and labor-intensive, and inefficient, and cannot meet the needs of batch workpiece processing.

[0004] After searching, relevant patents about sandblasting equipment for sandblasting the surface of the copper tube of the crystallizer have been disclosed. For example, the application case with Chinese patent application number CN201110375747.1 discloses a sandblasting device for the inner surface of the copper tube of the crystallizer, including a frame, a crossbeam is provided above the frame, a support plate is located above the crossbeam, a funnel is fixed on the frame below the right end of the support plate, a sandblasting machine is installed at the outlet below the funnel, and the sandblasting tube and the air jet tube connected to the sandblasting machine are connected to the nozzle. Although this application case performs sandblasting on the copper tube of the crystallizer, it uses a manual handheld nozzle to perform sandblasting from the left port of the copper tube to its inner surface. If the outer surface of the copper tube is sandblasted, a manual handheld nozzle is also required. Its operation is relatively cumbersome and inefficient, and its overall structure needs to be further improved. Summary of the invention

[0011] Preferably, the middle portion of the hole wall of the fixing hole is recessed inward to form an annular groove, and a plurality of rotatable driving wheels are evenly installed at the bottom of the annular groove. The annular clamp is rotatably installed in the annular groove, and the outer side wall of the annular clamp is in contact with the driving wheel, so that the annular clamp rotates by rotating the driving wheel.

[0012] Preferably, the mounting plate is provided with a plurality of spaced mounting grooves, the bottom of the clamping and fixing mechanism is provided with a mounting block, and the two clamping and fixing mechanisms are respectively clamped and installed in the corresponding mounting grooves on the mounting block through the mounting blocks at their bottoms.

[0013] Preferably, it also includes a sandblasting machine housing, which is correspondingly arranged on the top of the sandblasting machine base, and sandblasting tubes are correspondingly arranged around the inside of the sandblasting machine housing. A plurality of nozzles are correspondingly arranged on the sandblasting tube. The sandblasting tube can be connected to the sandblasting box through a pressure pump so that the sand material can be sprayed out through the nozzle and sprayed onto the surface of the crystallizer copper tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention enables a mounting plate to be rotatably mounted on a workbench at the top of a sandblasting machine base, and clamping and fixing mechanisms are correspondingly provided on both sides of the mounting plate, and the two clamping and fixing mechanisms are used to clamp and fix the two sides of the copper tube of the crystallizer; at the same time, the specific structure of the clamping and fixing mechanism is optimized and designed, and a rotatable annular clamp is correspondingly provided at the middle part of the fixing plate, and four clamping elements evenly provided on the inner side of the annular clamp are used to clamp and fix the side walls of the copper tube of the crystallizer, thereby realizing horizontal rotation and vertical flipping of the copper tube of the crystallizer, so as to better perform all-round sandblasting on the surface of the copper tube of the crystallizer.

[0016] In addition, the present invention has also optimized the design of the specific structure of the clamping element. The telescopic driving member drives the clamping head to extend and retract, thereby clamping the side wall of the copper tube of the crystallizer. At the same time, a clamping spring sheet is correspondingly provided at the end of the clamping head. Through the setting of the clamping spring sheet, on the one hand, the contact area with the copper tube of the crystallizer is increased, and on the other hand, the reverse elastic force of the clamping spring sheet is used to further clamp the side wall of the copper tube of the crystallizer, thereby improving its overall clamping and fixing 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.

The mounting plate 4 can be installed on the top of the workbench 3 by a rotating device such as a motor or a rotary cylinder, or a rotary workbench can be directly used, as long as the rotation of the mounting plate 4 can be achieved. Both sides of the mounting plate 4 are correspondingly provided with a clamping and fixing mechanism 5 for fixing the crystallizer copper tube 6, and the two sides of the crystallizer copper tube 6 are clamped and fixed by two clamping and fixing mechanisms 5 respectively, and can be flipped in the vertical direction.

The mounting block 7 can be slidably mounted in the mounting groove 401 and fixed by bolts on both sides. The two clamping and fixing mechanisms 5 are respectively mounted in the corresponding mounting grooves 401 on the mounting block 7 through the mounting blocks 7 at the bottom thereof. By providing a plurality of mounting grooves 401, the specific installation position of the clamping and fixing mechanisms 5 can be quickly adjusted according to the actual length of the crystallizer copper tube 6, so as to meet the actual production needs and improve its scope of application.

[0027] The clamping and fixing mechanism 5 includes a fixing plate 501, and an I-shaped mounting block 7 is correspondingly provided at the bottom of the fixing plate 501. A fixing hole 5011 is correspondingly provided in the middle of the fixing plate 501, and a rotatable annular clamp 502 is correspondingly installed in the fixing hole 5011. Four clamping elements 503 are evenly distributed around the inner side of the annular clamp 502. The side end of the crystallizer copper tube 6 passes through the middle of the annular clamp 502 and is clamped and fixed by the four clamping elements 503. The present invention provides a rotatable mounting plate 4 on the top of the workbench 3, and provides clamping and fixing mechanisms 5 on both sides of the mounting plate 4, and clamps and fixes the two sides of the crystallizer copper tube 6 through the two clamping and fixing mechanisms 5; at the same time, the specific structure of the clamping and fixing mechanism 5 is optimized and designed, and a rotatable annular clamp 502 is correspondingly provided in the middle of the fixing plate 501, and four clamping elements 503 evenly provided on the inner side of the annular clamp 502 are used to clamp and fix the side walls of the crystallizer copper tube 6, thereby realizing horizontal rotation and vertical flipping of the crystallizer copper tube 6, so as to better perform all-round sandblasting on the surface of the crystallizer copper tube 6. The operation is simple and convenient. Compared with the traditional method of first sandblasting the remaining surfaces of the crystallizer copper tube and then removing and flipping it and clamping it again for sandblasting, the processing time is effectively shortened, the efficiency is improved, the burden on the staff is reduced, and the demand for batch workpiece processing can be better met.

[0028] The clamping element 503 includes a telescopic driving member 5031 and a clamping head 5032. A groove is provided at a corresponding position on the inner side wall of the annular clamping member 502, and the telescopic driving member 5031 is installed in the groove on the inner side wall of the annular clamping member 502. The clamping head 5032 is installed at the telescopic end of the telescopic driving member 5031, and the side wall of the crystallizer copper tube 6 is pressed by the clamping head 5032. The telescopic driving member 5031 can be specifically a telescopic device such as a cylinder or an electric telescopic rod, as long as the telescopic movement of the clamping head 5032 can be achieved.

The middle part of the clamping spring sheet 5034 is correspondingly set to a long strip, and its two sides are correspondingly provided with outward arc edges. The middle portion of the clamping spring piece 5034 is connected to the clamping head 5032 , and the arc edges on both sides of the clamping spring piece 5034 are correspondingly pressed against the inner side wall of the annular clamp 502 . When not working, the telescopic drive component 5031 will control the clamping head 5032 and the clamping spring sheet 5034 to extend, so that the arc edges on both sides of the clamping spring sheet 5034 do not contact the inner wall of the annular clamp 502; when fixing the crystallizer copper tube 6, the telescopic drive component 5031 will control the clamping head 5032 and the clamping spring sheet 5034 to move to a suitable position, so that the clamping head 5032 presses the side wall of the crystallizer copper tube 6. At this time, the arc edges on both sides of the clamping spring sheet 5034 will also contact and squeeze the inner wall of the annular clamp 502, causing it to generate a reverse elastic force, further squeezing and clamping the side wall of the crystallizer copper tube 6, thereby improving its clamping and fixing effect; and the setting of the clamping spring sheet 5034 also increases the contact area with the crystallizer copper tube 6, so as to effectively improve its overall clamping and fixing effect. A spring shock absorber 5033 is correspondingly installed between the telescopic driving member 5031 and the clamping head 5032. The spring shock absorber 5033 is provided to absorb the vibration of the workpiece during the sandblasting process, thereby playing a shock absorbing role and improving the service life of the clamping and fixing mechanism 5.

[0029] The middle part of the hole wall of the fixing hole 5011 is inwardly recessed to form an annular groove, and a plurality of rotatable driving wheels 504 are evenly installed at the bottom of the annular groove. The annular clamp 502 is rotatably installed in the annular groove, and the outer wall of the annular clamp 502 is in contact with the driving wheel 504, and the annular clamp 502 is rotated by the rotation of the driving wheel 504. A driving device such as a small motor can be installed on the driving wheel 504, and the driving wheel 504 is controlled to rotate by the motor (for example, the Chinese patent application number CN202020037423.1, the Chinese patent application number CN202021902999.6, etc.), which belongs to the prior art and is very common at present, so it will not be elaborated here.

[0030] The sandblasting equipment of the present invention also includes a sandblasting machine housing 2, and the sandblasting machine housing 2 is correspondingly arranged on the top of the sandblasting machine base 1. The front side of the sandblasting machine housing 2 is correspondingly provided with a two-opening sealed door 201, and the sealed door 201 is correspondingly provided with an observation window 202, and the sealed door 201 is also correspondingly provided with a handle 203. The sandblasting machine housing 2 is correspondingly provided with a sandblasting tube around the inside, and the sandblasting tube is correspondingly provided with a plurality of nozzles. The sandblasting tube can be connected to the sandblasting box through a pressure pump so that the sand material can be sprayed through the nozzle and sprayed onto the surface of the crystallizer copper tube 6 to process the surface. The sandblasting machine base 1 can also be correspondingly provided with a sand material collection device to recover the sand material (the setting of the sandblasting tube and the recovery of the sand material here are common structures in the existing sandblasting machine, that is, they belong to the prior art, and are not the improvement of the present invention, so they are not elaborated here). It is worth noting that the present invention is mainly for sandblasting the outer wall of the crystallizer copper tube 6. By setting nozzles at special positions and special angles, the inner wall of the crystallizer copper tube 6 can also be sandblasted.
