Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of barrel surface processing, and particularly relates to an alloy barrel surface processing device of an extruder. BACKGROUND

[0002] The aluminum alloy barrel of the extruder is a core pressure-bearing component, and the surface thereof needs to have wear resistance, hardness, corrosion resistance and dimensional stability. The surface of the aluminum alloy barrel of the extruder needs to be sandblasted during processing. For the extruder barrel that needs to be overlaid or sprayed with wear-resistant alloy (such as a bimetallic barrel), sandblasting is a necessary prerequisite for obtaining good metallurgical bonding or mechanical bonding. Sandblasting forms a uniform and microscopically rough profile on the surface of the barrel. Such roughness greatly increases the surface area, providing excellent mechanical bonding force (anchoring effect) for subsequent coatings (such as wear-resistant alloy coating, corrosion-resistant coating, bimetallic layer) or adhesion.

[0003] At present, when the surface of the aluminum alloy barrel is sandblasted, it is generally manually held by a sandblasting gun to sandblast the surface, or the barrel is placed on a conveying roller and clamped and fixed by a three-jaw clamping mechanism. During sandblasting, the three-jaw clamping mechanism drives the barrel to move under the sandblasting gun and rotates the barrel, so that the barrel is sandblasted at the part under the sandblasting gun. After the part is processed, the barrel is moved a distance again for sandblasting until the barrel is completely sandblasted. The above-mentioned method is to clamp and fix each barrel separately during sandblasting. After the sandblasting of one barrel is completed, the barrel needs to be removed before a new barrel can be placed for processing, which leads to a complex processing operation mode, a long clamping time and low processing efficiency. Therefore, the alloy barrel surface processing device of the extruder is designed. SUMMARY

[0024] A part of the side of the abutting head 732 close to the driving ring 63 is cut off to form an abutting inclined surface 733, a plurality of contact balls 75 are embedded in the abutting inclined surface 733 at equal intervals, the contact balls 75 enable the abutting head 732 to slide with the driving inclined surface 631, and the abutting head 732 can also rotate circumferentially along the driving inclined surface 631, the contact balls 75 roll with the driving inclined surface 631 of the driving ring 63, the side of the abutting head 732 close to the driving ring 63 is arc-shaped, and the slope of the abutting inclined surface 733 is the same as the slope of the driving inclined surface 631; When the push rod of the electric push rod 61 is elongated to make the driving ring 63 as a whole move to the left, the driving inclined surface 631 on the driving ring 63 will push the contact balls 75 to make the abutting head 732 move to the side away from the driving ring 63, so that the whole clamping rod 73 and the clamping arc plate 72 move to the side away from the driving ring 63, that is, the plurality of clamping arc plates 72 will be synchronized to move inward and close to each other, so that the plurality of clamping arc plates 72 clamp and fix the workpiece at the same time; Conversely, when the driving ring 63 moves to the right under the action of the electric push rod 61, since the jacking spring 74 makes the clamping rod 73 always have a tendency to move to the side of the driving ring 63, the clamping arc plate 72 will move to the side of the driving ring 63 away from the workpiece under the action of the jacking spring 74, and the clamping and fixing of the workpiece are released; When the driving ring 63 is at the rightmost inside of the moving collar 6, the upper left of the driving slope 631 is still in contact with the contact ball 75, which facilitates the subsequent driving of the ring 63 to the left to push the abutting head 732 again.

[0025] Referring to Figures 5-9 , the turnover structure 8 comprises a driving gear 82, the right side of the driving gear 82 is welded with a mounting collar 821, the lower right side of the moving collar 6 is fixed with a fixed shaft seat 822, the fixed shaft seat 822 is rotatably connected with the driving gear 82 through bearings and the mounting collar 821, the lower side of the moving collar 6 is provided with an engagement notch 601 of arc structure, the outer ring of the rotating ring 62 is provided with a plurality of engagement grooves 621 arranged in an annular array, the driving gear 82 is engaged with the engagement grooves 621 through the engagement notch 601, and the rotation of the driving gear 82 can make the rotating ring 62 rotate circumferentially, so that the plurality of clamping structures 7 fixed on the rotating ring 62 rotate synchronously, and the workpiece between the plurality of clamping structures 7 can also rotate synchronously.

[0026] The upper side of the base 1 is rotatably installed with a transmission shaft 83 through a bearing seat, a plurality of key grooves 831 arranged in an annular array are formed on the outer surface of the transmission shaft 83, a plurality of connecting keys 823 uniformly distributed are integrally formed on the inner ring of the mounting collar 821, the mounting collar 821 is slidingly inserted on the transmission shaft 83, and the plurality of connecting keys 823 are respectively slidingly arranged in the plurality of key grooves 831, when the moving collar 6 moves left and right, the mounting collar 821 and the driving gear 82 can move left and right linearly along the transmission shaft 83, a speed reducer 81 is installed on the upper side of the base 1, and the transmission shaft 83 is connected with the output end of the speed reducer 81.

[0027] Working principle: in the initial state, the push rod of the hydraulic cylinder 5 is in the elongated state, at this time, the plurality of moving collars 6 are at the rightmost end that can be moved, and the push rod of the electric push rod 61 is in the telescopic state, the driving ring 63 is at the rightmost inside of the moving collar 6, the clamping arc plates 72 in the plurality of clamping structures 7 are away from each other under the action of the jacking spring 74, and the circular inner diameter formed by the plurality of clamping arc plates 72 is greater than the outer diameter of the cylinder.

[0028] First, the same is placed on the upper right side of the plurality of guide rollers 2, and the cylinder is pushed to the left for a distance, so that the left end of the cylinder is partially inserted into the inside of the moving collar 6, then the elongation of the push rod of the hydraulic cylinder 5 can drive the push frame 51 and the two moving columns 4 to move rightward synchronously along the guide frame 11, thereby driving the plurality of moving collars 6 and the clamping structure 7 to move rightward synchronously, at this time, the circular inner diameter formed by the plurality of clamping arc plates 72 is greater than the outer diameter of the cylinder, so the left end of the cylinder will be inserted into the circular structure formed by the plurality of clamping arc plates 72; Afterwards, the push rod of the electric push rod 61 is elongated, so that the driving ring 63 as a whole moves to the left, and the driving slope 631 on the driving ring 63 will push the contact ball 75, so that the abutting head 732 moves away from the side of the driving ring 63, and in turn, the whole clamping rod 73 and the clamping arc plate 72 move away from the side of the driving ring 63, that is, the plurality of clamping arc plates 72 will synchronously move inward and close to each other, and in turn, the plurality of clamping arc plates 72 are in contact with the outer surface of the cylinder at the same time to clamp and fix; After the plurality of clamping arc plates 72 clamp and fix the outer surface of the cylinder, the push rod of the hydraulic cylinder 5 is retracted, so that the moving sleeve ring 6 and the clamping structure 7 synchronously move to the left by a distance, so that the cylinder clamped in the plurality of clamping structures 7 moves along the guide roller 2 to the left by a distance, which is less than the width that can be sandblasted by the sandblasting structure. This cycle makes the leftmost end of the cylinder extend into the processing box 3, and after the left end of the cylinder is below the sandblasting structure, the sandblasting machine will perform sandblasting treatment on the surface of the cylinder through the sandblasting structure. During the sandblasting treatment, the speed reducer 81 will make the transmission shaft 83 rotate, and the rotating transmission shaft 83 will drive the driving gear 82 to rotate through the connecting key 823, so that the rotating ring 62 synchronously rotates with the driving gear 82. The rotation of the rotating ring 62 can drive the plurality of clamping structures 7 on the rotating ring 62 to rotate together, so that the cylinder clamped on the plurality of clamping structures 7 rotates circumferentially. The cylinder can be fully sandblasted during rotation.

[0029] After the cylinder rotates one circle, the push rod of the electric push rod 61 is retracted, so that the driving ring 63 moves to the right under the action of the electric push rod 61. Since the clamping rod 73 always has a tendency to move to the side of the driving ring 63 due to the jacking spring 74, the clamping arc plate 72 will move away from the workpiece to the side of the driving ring 63 under the action of the jacking spring 74, thereby releasing the clamping and fixing of the workpiece. Then, the push rod of the hydraulic cylinder 5 is elongated again to drive the push frame 51 and the two moving columns 4 to synchronously move to the right along the guide frame 11, and in turn, the plurality of moving sleeve rings 6 and the clamping structures 7 synchronously move to the right. Then, the electric push rod 61 drives the clamping structure 7 to clamp and fix the cylinder through the driving ring 63. Then, the hydraulic cylinder 5 synchronously moves the moving sleeve ring 6 and the clamping structure 7 to the left by a distance, and in turn, the cylinder synchronously moves to the left. Then, the cylinder rotates one circle for sandblasting treatment, so that the cylinder continuously and intermittently moves to the left, and after each movement to the left by a distance, the part below the sandblasting structure can be fully sandblasted, until the cylinder is fully sandblasted.

[0030] When the right side remaining part of the barrel is not sandblasted, the guide roller 2 on the right side of the device has a larger space at this time, and the new barrel to be sandblasted can be directly placed above the guide rollers 2, and the barrel can be continuously moved to the left, and after the sandblasting of the previous barrel is completed, the barrel can also smoothly enter the sandblasting process, and the operation is continuously repeated, so that the barrels can be continuously sandblasted, improving the processing efficiency.

[0031] By arranging a plurality of linearly distributed moving collars 6, the plurality of moving collars 6 are synchronously linearly moved through the moving column 4, and the clamping structure 7 arranged in the moving collar 6 and the driving ring 63 are matched, the clamping structure 7 can clamp and fix the barrel, and intermittently move the barrel, so that the barrel can enter the sandblasting structure below for processing in sections, and the barrels can be continuously sandblasted while feeding and discharging, improving the processing efficiency. By rotatingly installing the rotating ring 62 in the moving collar 6, the clamping structure 7 is installed on the rotating ring 62, and the clamping structure 7 and the driving ring 63 can be simultaneously slidably and rotatably connected, and the overturning structure 8 is matched, the barrel can be rotated after moving a section under the sandblasting structure, so that the barrel can be sandblasted in all directions, improving the processing efficiency.
