Description
Technical field
The present invention relates to welded tube weld seam treating apparatus, particularly relate to a kind of welded tube weld seam pressuring flat device.
Background technology
The employed stainless steel welded pipe of industry such as chemical industry, food hygiene all requires its smooth welded seam, clearly stipulated the width of Welded Joint in Steel butt welded seam and the requirement of reinforcement among the mechanical industry standard JB/T7949-1999 of China " Steel Structure Weld appearance and size ", required to seamlessly transit between welding bead and welding bead and welding bead and the base metal.
Be arranged on the apparatus for producing tube welded tube weld reinforcement treatment facility afterwards of stainless steel welded pipe manufacturing process at present, the normal processing mode that adopts is: inner wall of welded pipe adopts special cutter to wipe crator off, and the welded tube outside adopts glossing to remove crator.The shortcoming that adopts cutter and glossing is that after treatment welded tube surfaces externally and internally exists unfavorable tool marks, influences the quality of welded tube.For stainless steel welded pipe, the commissure exists metal molten and recrystallization process in the manufacturing process, performance parameters such as the hardness on weld seam and joint edge edge, intensity, toughness and base metal there are differences, only adopt simple polishing, cutter to scrape technology and be difficult to eliminate this species diversity, cause product quality to descend the most at last.
Summary of the invention
Purpose of the present invention promptly provides the welded tube weld seam pressuring flat device that a kind of mode that rolls by roll flattens weld seam, can satisfy the quality requirement of welded tube product after the use fully, and the precision height, and the scope of application is wide.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of welded tube weld seam pressuring flat device, comprise guide holder and be located at roll mount pad on the guide holder, it is characterized in that, described roll mount pad comprises dolly, and dolly is provided with lift cylinder, bottom roll, topping roll, lift cylinder that links to each other with topping roll and the adjusting knob that links to each other with bottom roll; Described pressuring flat device also is provided with the plug that places in the welded tube, be fixed on the plug fixed block on the guide holder and connect the spring of plug fixed block and plug.
Preferably, described guide holder comprises that frame and level be located at two parallel guide bars on the frame.
Preferably, described topping roll and described bottom roll all have groove, and the groove diameter of topping roll is greater than the groove diameter of bottom roll.
Preferably, the weld seam of described welded tube places in the groove of described bottom roll.
Preferably, also be provided with a coolant pipe on the guide holder of described pressuring flat device, cooling fluid flow on the described bottom roll in the pipe.
Preferably, the horizontal air cylinder of described pressuring flat device and lift cylinder all adopt PLC to control automatically.
The mode that welded tube weld seam pressuring flat device of the present invention rolls by roll flattens the welded tube weld seam, use between back welding bead and welding bead and welding bead and the base metal to seamlessly transit, and the performance parameter difference of welding bead and base metal is little, can satisfy the product quality requirement fully; Use PLC (Programmable Logic Controller, Programmable Logic Controller) control, the precision height; Have adjusting knob and can satisfy welded tube diameter in a big way, the scope of application is wide.

The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, a kind of welded tube weld seam pressuring flat device, comprise guide holder and be located at roll mount pad on the guide holder, the roll mount pad comprises dolly 7, and dolly 7 is provided with horizontal air cylinder 6, bottom roll 3, topping roll 5, lift cylinder 8 that links to each other with topping roll 5 and the adjusting knob 11 that links to each other with bottom roll 3; Also be provided with the plug 4 that places in the welded tube 12 in addition, be fixed on the plug fixed block 10 on the guide holder and connect the spring 1 of plug fixed block 10 and plug 4.Guide holder comprises that frame 13 and level be located at two parallel guide bars 9 on the frame 13.
After welded tube steel band roll forming and the welding, insert plug 4 and coupled spring 1 therein, topping roll 5 and bottom roll 3 all have groove, and weld seam 2 places the groove of bottom roll 3.Adjusting knob 11 is regulated bottom roll 3 in the vertical direction displacement, makes bottom roll 3 block welded tube 12.Dolly 7 places on two parallel guide bars 9 of guide holder, can do horizontal reciprocating movement on guide holder under the piston pulling of horizontal air cylinder 6.Lift cylinder 8 pistons descend, and drive topping roll 5 and descend, and the groove of topping roll 5 blocks welded tube 12.The groove diameter of topping roll 5 is greater than the groove diameter of bottom roll 3, wherein bottom roll 3 less groove diameter can increase the pressure of its butt welded seam 2, and topping roll 5 bigger groove diameter can reduce its pressure to welded tube 12, prevent that the tube wall of welded tube 12 from being pressed modification.
Dolly 7 is advanced along the tubulation direction, the roll rotation, roll weld seam 2 prominences by 4 pairs of welded tubes 12 of plug, clamping plug 4 simultaneously travels forward, the spring 1 that connects plug fixed block 10 and plug 4 stretches, dolly 7 walks to terminal point, horizontal air cylinder 6 commutations, the lift cylinder 8 that link to each other with topping roll 5 this moment rises, and topping roll 5 rises, the grinding pressure of 3 pairs of welded tubes 12 of bottom roll disappears, upper and lower roll also disappears to the clamping action of plug 4, spring 1 retraction, and plug 4 is got back to the home position, for rolling, next round prepares, so repeatedly.Horizontal air cylinder 6 and lift cylinder 8 all adopt PLC (Programmable Logic Controller, Programmable Logic Controller) control automatically, can control its stroke, make dolly 7 speeds of service much larger than tubulation speed, roll surpasses 30 times the per minute that rolls of welded tube 12, guarantees that weld seam 2 and base metal seamlessly transit.
The guide holder of pressuring flat device is provided with a coolant pipe 14, selects different cooling fluid types for use according to different welded tube materials, and cooling fluid flow on the bottom roll 3 that rolls weld seam 2, can reduce its frictional heat, takes away heat, prevents the cause thermal damage device.
