All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the present embodiment provides a stainless steel bellows processing apparatus, which includes a base 1, and a conveying mechanism 2, a cleaning mechanism 4 and a forming mechanism 3 are sequentially disposed on the base 1 along a moving direction of a steel pipe 5.
In stainless steel course of working, drive steel pipe 5 through conveying mechanism 2 and remove to the direction of forming mechanism 3 gradually, conveying mechanism 2 restriction steel pipe 5 rotates simultaneously, makes steel pipe 5 process into the bellows in forming mechanism 3 department, and before forming mechanism 3 processing, clearance mechanism 4 is cleared up steel pipe 5 surface, avoids debris to adhere to steel pipe 5 surface, the condition of stamping on steel pipe 5 during processing takes place.
Referring to fig. 1, the forming mechanism 3 includes a turntable 31, a first through hole 33 is formed in the middle of the turntable 31, two extrusion units 34 for extruding the steel pipe 5 are fixedly mounted on the turntable 31, and a first driving member 32 for driving the turntable 31 to rotate is mounted on the turntable 31.
The conveying mechanism 2 drives the steel pipe 5 to pass through the first through hole 33 on the rotary table 31, wherein when the steel pipe 5 passes through the extrusion unit 34, the extrusion unit 34 extrudes the surface of the steel pipe 5, so that the surface of the steel pipe 5 is stressed to be concave, and meanwhile, the rotary table 31 is driven by the first driving piece 32 to rotate, so that the surface of the steel pipe 5 forms an annular concave, and then a corrugated pipe is formed.
Referring to fig. 1, two extrusion units 34 are disposed opposite to each other on two sides of the steel pipe 5. The extrusion force of the extrusion unit 34 on the steel pipe 5 is uniformly distributed, and the situation that the steel pipe 5 is extruded and deviated by one side of the extrusion unit 34 is reduced.
Referring to fig. 1-3, further, the extruding unit 34 includes a housing 341, two transmission gears 342 are rotatably mounted in the housing 341, a toothed belt 343 is sleeved on the two transmission gears 342, an electric motor for driving the transmission gears 342 to rotate is fixedly mounted on the housing 341, a plurality of pressing heads 344 are fixedly mounted on the toothed belt 343, a notch 345 is formed on one side of the housing 341 close to the steel pipe 5, and when the pressing heads 344 move to one side of the toothed belt 343 close to the steel pipe 5, the pressing heads 344 pass through the notch 345 and are abutted against the surface of the steel pipe 5.
When the steel pipe 5 moves between the two extrusion units 34, the surface of the steel pipe 5 is firstly contacted with the pressure head 344, wherein the driving gear 342 drives the toothed belt 343 to move so as to drive the pressure head 344 to move, so that the pressure head 344 contacted with the steel pipe 5 and the steel pipe 5 synchronously move along the axial direction of the steel pipe 5, thereby avoiding the steel pipe 5 from being separated from the pressure head 344.
The existing corrugated steel pipe is generally formed by instantaneous extrusion of each corrugated steel pipe, so that the mechanical properties of the steel pipe are seriously damaged, and the processed corrugated steel pipe is poor in flexibility and low in service life.
Referring to fig. 4-6, in order to solve the above-mentioned technical problem, the pressing head 344 includes a fixed block 346 and a top block 347, a sliding hole 348 is formed in the fixed block 346, the axis is perpendicular to the side surface of the toothed belt 343, the top block 347 is located in the sliding hole 348 and slidingly connected with the sliding hole 348, an inclined guide plate 349 is disposed on the inner wall of the casing 341, when the top block 347 moves to move in the same direction as the steel pipe 5, one side of the top block 347 contacts with the surface of the steel pipe 5, the other side of the top block 347 contacts with the surface of the inclined guide plate 349, and the perpendicular distance between the side surface of the inclined guide plate 349 and the axis of the steel pipe 5 along the moving direction of the steel pipe 5 is gradually reduced.
The steel pipe 5 is driven by the conveying mechanism 2 to contact with the top block 347, the top block 347 contacted with the steel pipe 5 moves along with the movement of the steel pipe 5, the side surface of the inclined guide plate 349 gradually reduces along the vertical distance between the moving direction of the steel pipe 5 and the axis of the steel pipe 5 due to the fact that the other side of the top block 347 contacts with the inclined guide plate 349, one end of the top block 347 contacted with the steel pipe 5 gradually penetrates into the extrusion unit 34 along with the steel pipe 5, the top block 347 also gradually penetrates into the steel pipe 5, meanwhile, the top block 347 is driven to circumferentially rotate around the axis of the steel pipe 5 due to the rotation of the turntable 31, and accordingly when the top block 347 extrudes the surface of the steel pipe 5, the formed groove 6 is evenly balanced in an arc shape, and along with the movement of the steel pipe 5, the top block 347 gradually pushes the groove 6 formed on the surface of the steel pipe 5 to shrink towards the inner wall of the steel pipe 5, and the corrugated pipe is manufactured.
Due to the operation, the annular groove 6 of the steel pipe 5 is subjected to multiple spinning gradual change molding, so that the mechanical properties and physical properties of raw materials are reserved to the greatest extent, the molding parameters of the corrugated pipe are optimized, the corrugated pipe is softer, the fatigue resistance times are improved, and the service life of the corrugated pipe is greatly prolonged.
In order to avoid the deviation of the top block 347 when it contacts the steel pipe 5 during the movement of the fixing block 346 by the belt, an error occurs in the processed groove 6.
Referring to fig. 4 and 5, a roller 353 is rotatably mounted on a side of the fixed block 346 away from the toothed belt 343, a baffle 354 is fixedly mounted on an inner wall of the housing 341, and when the fixed block 346 moves to a side of the belt close to the steel pipe 5, the roller 353 abuts against the baffle 354.
The contact between the roller 353 and the shutter 354 restricts the occurrence of the condition in which the fixed block 346 moves to bring the top block 347 into deflection.
Referring to fig. 3, in order to reduce friction between the top block 347 and the inclined guide plate 349, one end of the top block 347 located inside the tooth belt 343 is rotatably mounted with a roller 355.
Referring to fig. 5, in order to avoid the situation that the top block 347 deforms by extrusion on the sidewall of the groove 6 formed on the surface of the steel pipe 5 when the top block 347 is turned over, that is, the top block 347 can be separated from the groove 6 in time when turned over, so as to reduce the excessive influence on the forming groove 6. The toothed belt 343 comprises a translation region 3431 and a turnover region 3432, the length of the inclined guide block projected to the translation region 3431 along the moving direction of the steel pipe 5 is smaller than the length of the translation region 3431, a tension spring 350 is fixedly arranged between the top block 347 and the inner wall of the through hole, and when the top block 347 is contacted with the inclined guide plate 349, the tension spring 350 is in a tension state.
The top block 347 on the fixed block 346 moves along the direction of the steel pipe 5 under the driving of the toothed belt 343, the top block 347 gradually moves towards the axis direction of the steel pipe 5 under the pushing of the inclined guide plate 349, and generates a tensile force on the tension spring 350, so that the tension spring 350 is stretched and deformed, meanwhile, the top block 347 presses the surface of the steel pipe 5 to form a groove 6 and deepens the groove 6 gradually, when the top block 347 moves to be separated from the inclined guide plate 349, the top block 347 is still in the translation region 3431 at this time, and the top block 347 is separated from the groove 6 along the radial direction of the steel pipe 5 under the action of the elastic force of the spring due to the fact that the top block 347 is not pushed by the inclined guide plate 349, so that the situation that the side wall of the extrusion groove 6 is deformed due to the fact that the top block 347 moves to the turnover region 3432 cannot be separated from the groove 6 in time is avoided.
The depth of the groove 6 machined on the surface of the steel pipe 5 in the machining process is different according to the different diameters of the steel pipe 5 or the required machining size of the steel pipe 5 due to different machining requirements of different steel pipes 5.
Referring to fig. 3 and 5, in order to solve the above-mentioned problems, a shaft cylinder 351 and an adjusting unit 36 for adjusting the rotation of the inclined guide plate 349 are fixedly installed on one side of the inclined guide plate 349 away from the steel pipe 5, a supporting rod 352 is rotatably installed on the shaft cylinder 351, two ends of the supporting rod 352 are fixedly connected with the housing 341, and the adjusting unit 36 is closer to one end of the inclined guide plate 349, which is closer to the turntable 31, than the shaft cylinder 351.
When it is necessary to adjust the depth of the pressing unit 34 pressing the groove 6 against the steel pipe 5. The inclined guide plate 349 is driven to rotate around the axis of the shaft cylinder 351 by the adjusting unit 36, so that one end of the inclined guide plate 349, which is close to the turntable 31, moves towards the direction of the steel pipe 5, the vertical distance between one end of the inclined guide plate 349, which is close to the turntable 31, and the steel pipe 5 is reduced, and the depth of the groove 6 applied by the top block 347 on the surface of the steel pipe 5 is deeper in the process that the top block 347 abuts against the inclined guide plate 349.

Referring to fig. 1, 7 and 8, the cleaning mechanism 4 includes a shaft 41 fixedly mounted on the supporting disk 38, a linkage gear 42 is rotatably mounted on a surface of the shaft 41, a first positioning block 43 is fixedly mounted on a shaft side surface of the linkage gear 42, a second positioning block 44 is fixedly mounted on a peripheral side surface of the shaft 41, a return spring 45 is fixedly mounted between the shaft 41 and the linkage gear 42, the return spring 45 is a spiral spring, a brush plate 47 is fixedly mounted on a side, away from the supporting disk 38, of the linkage gear 42, an arc toothed plate 46 for meshing with the linkage gear 42 is fixedly mounted on the second arc bracket 40, and a material removing plate 48 is fixedly mounted on a side, away from the supporting disk 38, of the arc toothed plate 46.
In the initial state, the first positioning block 43 is abutted with the second positioning block 44, the linkage gear 42 is in a static state relative to the shaft rod 41, the brush plate 47 is in surface contact with the steel pipe 5, when the linkage gear 42 moves to be meshed with the arc toothed plate 46, the first positioning block 43 is separated from the second positioning block 44, the linkage gear 42 drives the brush plate 47 to rotate towards the material removing plate 48 until the brush plate 47 is contacted with the material removing plate 48, and when the linkage gear 42 is separated from the arc toothed plate 46, the scroll spring drives the linkage gear 42 to rotate, and the brush plate 47 is restored to the initial position.
In the process that the steel pipe 5 passes through the supporting plate 38, the hairbrush plate 47 arranged on the supporting plate 38 is contacted with the surface of the steel pipe 5, and meanwhile, the supporting plate 38 rotates along with the rotary plate 31, so that the hairbrush plate 47 is driven to rotate together, and the surface of the steel pipe 5 is cleaned comprehensively. In order to avoid that the brush plate 47 has too much attachments carried on the surface during cleaning the steel pipe 5, the cleaning effect is poor, and the attachments are easy to separate from the brushes and adhere to the surface of the steel pipe 5 again.
As shown in fig. 7, when the supporting disk 38 drives the brush plate 47 to rotate clockwise, the driving gear is brought into contact with the arc toothed plate 46, so that the driving gear drives the brush plate 47 to rotate counterclockwise relative to the shaft 41, meanwhile, the first positioning block 43 is separated from the second positioning block 44, the spiral spring is internally contracted to collect elastic potential energy, and as the supporting disk 38 continues to rotate, the rotation angle of the brush plate 47 is larger until the brush heads on the brush plate 47 face downwards and contact with the material removing plate 48, and in the process of the brush on the brush plate 47 and the material removing plate 48, the brush shakes, and most of attachments on the brush are separated from the brush.
When the supporting disk 38 drives the brush plate 47 to move upwards, the driving gear is separated from the arc toothed plate 46, the spiral spring drives the driving gear to reset and rotate relative to the shaft rod 41, and the rotation is stopped until the first positioning block 43 is abutted with the second positioning block 44, at this time, the brush on the brush head is also contacted with the surface of the steel pipe 5 again, and cleaning work is continuously performed on the surface of the steel pipe 5.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
