Description

Technical Field

[0001] The invention relates to the technical field of tank production lines, and in particular to a fire extinguisher tank production line. Background Art

[0002] As we all know, a fire extinguisher is a portable fire-fighting tool with chemicals placed inside to assist in extinguishing fires. With the advancement of urbanization, more and more people are living in clusters, so fire safety is more important. Tank fire extinguishers, as one of the effective fire-fighting equipment, have been widely used. The large demand for tank fire extinguishers has also led to a large demand for fire extinguisher tanks. In order to facilitate the preparation of fire extinguisher tanks, we propose a fire extinguisher tank production line.

[0003] After searching, the Chinese patent publication number CN116586996A and the patent publication number CN118180886B respectively disclose a cutting and welding robot system for stainless steel tanks and a chemical material storage tank welding device, wherein the former is roughly described as including an industrial robot arranged on a rotating platform and controlled by a control system, a clamping quick-change joint arranged at the end of the mechanical arm of the industrial robot, a plasma cutting head, an electric grinding head and a welding gun arranged on the rotating platform, a lifting platform arranged at the center position of the rotating platform, and a clamping device and a laser ranging sensor arranged on the lifting platform for clamping the lower end cover of the stainless steel tank. When in use, the plasma cutting head, the electric grinding head and the welding gun are respectively connected to the control system circuit, and work after being clamped by the quick-change joint in steps. The rotating platform and the lifting platform are respectively connected to the control system circuit, and are respectively controlled by the control system to move and fix. The industrial robot is driven by a rotating platform controlled by a control system to rotate around a stainless steel tank body, the latter of which is roughly described as comprising a base, a track plate is fixedly connected to the base, and two tank support blocks arranged in a front-to-back mirrored manner are slidably connected above the track plate, two longitudinal slide grooves arranged in a front-to-back manner are opened on the base and on the left side of the track plate, wherein a cleaning unit is slidably connected in the longitudinal slide groove on the front side, a transverse slide groove is opened on the base and on the left side of the longitudinal slide groove, and two groups of No. 1 electric sliders are slidably connected in the transverse slide groove, wherein a positioning hammer unit is fixedly connected to the No. 1 electric slider on the left side, when in use, the cleaning unit can grind and scrape the weld on the surface of the tank body through grinding parts and scraping parts, can effectively scrape off the welding slag, and can automatically adjust the pressure applied to the tank body by the grinding parts and scraping parts according to the height of the protrusion on the weld through the distance between the guide arc rail and the track arc plate.

[0004] Although the above two existing technical solutions can be used for the welding, forming and cutting operations of the tank body, it can be obviously judged based on the technical solutions of the two combined with their corresponding operating methods that the former is more suitable for the operation of large tanks, while the latter is a single welding station. It is difficult to form an assembly line production mode during the welding operation of both. In order to improve the operational convenience of the fire extinguisher, the fire extinguisher tank body mostly adopts a smaller size. Therefore, the applicability of the existing technical solution is poor, and the production efficiency needs to be further improved. Summary of the invention

When the double-sided pressure roller 48, the gradually deformed pressure roller 49, the spherical pressure roller 50, the centering flanging pressure roller 51, the centering deformed pressure roller 52, the fully closed pressure roller 53 and the multiple upper conveying rollers 66 run smoothly, the sheet material for preparing the fire extinguisher tank body is fed from the rear of the double-sided pressure roller 48, the double-sided pressure roller 48 and the double-sided support rollers 54 cooperate to roll and roll to form the first-level rolling treatment of the sheet material, the gradually deformed pressure roller 49 and the gradually deformed support roller 55 cooperate to roll and roll to form the second-level rolling treatment of the sheet material, and the spherical pressure roller 50 and the spherical support roller 56 cooperate to roll and roll to form the sheet material The sheet is formed into a tube by the three-stage rolling treatment, the centering flanging roller 51 and the centering flanging support roller 57 cooperate to roll and roll to form the four-stage rolling treatment of the sheet, the centering deformation roller 52 and the centering deformation support roller 58 cooperate to roll and roll to form the five-stage rolling treatment of the sheet, and the fully closed roller 53 and the fully closed support roller 59 cooperate to roll and roll to form the six-stage rolling treatment of the sheet, and the sheet is formed into a tube. The centering flanging roller 51 and the centering deformation roller 52 are both provided with an intermediate alignment separation ring to ensure that the conveying direction of the sheet is maintained during the rolling process of the sheet into the tube, and to ensure the alignment of the weld gap of the tube with the inner welding head 4 and the outer welding head 5.

[0028] Furthermore, when the pipe material passes over the parallel mounting frame 24, the first electric drive rod 25 works to control the transmission column 27 to move relative to the cantilever mounting tube 21. Under the transmission action of the transmission column 27, the moving transmission column 27 will realize the rotational drive of the first parallel rod 22 relative to the cantilever mounting tube 21. The first parallel rod 22 rotating relative to the cantilever mounting tube 21 can realize the distance between the parallel mounting frame 24 and the cantilever mounting tube 21, that is, the inner welding head 4 on the parallel mounting frame 24 and the double-sided roller 40 are close to the welding seam to be welded of the pipe material, and finally the double-sided roller 40 contacts the inner side wall of the pipe material and forms an interaction force, which is transmitted to the upper probe frame 39 via the double-sided roller 40, and finally passes through the elastic connected to the upper probe frame 39. The transmission of the elastic spring 43 and the pressure plate 44 in the elastic spring 43 forms a pressure value on the pressure sensor 45 in the parallel mounting frame 24, and the relative position between the inner welding head 4 and the pipe material is recognized according to the pressure value, so that the inner welding head 4 has a suitable welding distance, and in order to ensure the welding quality of the inner welding head 4, the parallel mounting frame 24 is located below the fully closed pressure roller 53, so as to ensure that the double-sided roller 40 will not cause the expansion of the weld seam of the pipe material when the double-sided roller 40 applies pressure to the pipe material. After the welding of the inner welding head 4 is completed, the pipe material will pass directly under the outer welding head 5. When the pipe material passes directly under the outer welding head 5, the second electric drive rod 38 is powered on to realize the relative position adjustment of the lifting frame 37 relative to the outer welding mounting frame 3, so as to form a relative position between the outer welding head 5 and the middle side roller 42. As the pipe approaches, the middle side roller 42 finally contacts the outer side wall of the pipe and forms an interaction force, which is transmitted to the lower probe frame 41 via the middle side roller 42, and finally forms a pressure value for the pressure sensor 45 in the lifting frame 37 through the transmission of the elastic spring 43 connected to the lower probe frame 41 and the pressure transmission plate 44 in the elastic spring 43. The relative position between the outer welding head 5 and the pipe is identified based on the pressure value, so that the inner welding head 4 has a suitable welding distance. When the detection values ​​of the two pressure sensors 45 are read and judged by the control processing computer, the welding machine is powered on to realize the welding operation of the inner welding head 4 and the outer welding head 5, and also controls the first electric drive rod 25 and the second electric drive rod 38 to stop running, so as to achieve the inner welding. The relative position of the joint 4 relative to the pipe material is maintained, and the relative position of the external welding joint 5 relative to the pipe material is maintained. After welding, the pipe material will be transported into the fixed frame 6 through the rotation of the upper conveying roller 66 and the lower conveying roller 67. According to the movement of the pipe material relative to the fixed frame 6, the two spindle motors 18 are powered on to realize the rotation drive of the two synchronous cutting blades 9 respectively, and the rotation operation state of the two synchronous cutting blades 9 is maintained. The servo motor 28 is powered on to realize the rotation drive of the driving rotating frame 29. Under the transmission action between the spiral side groove 30 and the transmission pin 33, the rotating driving rotating frame 29 will realize the movement of the mobile frame 7 relative to the fixed frame 6, and the moving speed of the mobile frame 7 is controlled to be the same as the moving speed of the pipe material, so as to realize the relative stillness between the pipe material and the mobile frame 7.After that, the electric telescopic rod 10 works to realize the synchronous motion drive of the two drive sleeves 13 through the synchronous drive ring 11. Under the transmission action of the two drive columns 19 and the two threaded grooves 20 respectively, the synchronous motion of the two drive sleeves 13 will realize the synchronous relative rotation drive of the two mounting shafts 12, so that the two rotating arms 16 form a synchronous rotation motion, and finally the relative positions of the two synchronous cutting blades 9 relative to the pipe material are close, until the two synchronous cutting blades 9 form a cutting depth relative to the pipe material that exceeds the wall thickness of the pipe material, and then the electric telescopic rod 10 stops.

[0029] Furthermore, the reduction motor 34 is powered on to realize the rotation drive of the driving gear 35. Under the meshing action of the driving gear 35 and the transmission gear 36, the rotating driving gear 35 realizes the rotation drive of the annular frame 8 relative to the moving frame 7. The rotation of the annular frame 8 will drive the two synchronous cutting blades 9 to form a synchronous rotation movement. The two synchronously rotating synchronous cutting blades 9 will realize the annular cutting of the pipe material, forming the cutting of the pipe material. After the pipe material is cut, the electric telescopic rod 10 enters the shortened state from the parked state. Under the transmission action of the synchronous driving ring 11, the two driving sleeves 13, the two driving columns 19 and the two mounting shafts 12, the reverse rotation reset of the two rotating arm frames 16 is realized, so that the two synchronous cutting blades 9 on the two rotating arm frames 16 are synchronously moved away from the pipe material, and the moving speed of the pipe material is controlled. The size of the gradual quick reset groove 31 is adapted so that after the synchronous cutting blade 9 completes the entire process of entering, circular cutting and retracting the cutting blade relative to the pipe material, the transmission pin 33 just completely moves in the spiral side groove 30, that is, the synchronous cutting blade 9 completes one cutting, and the transmission pin 33 just completely passes through the spiral side groove 30, and moves out of the spiral side groove 30 and enters the gradual quick reset groove 31, so as to facilitate the rapid movement and reset of the movable frame 7 relative to the fixed frame 6, in preparation for the cutting operation of the next pipe material cutting position. Along with the cutting of the pipe material, the pipe material to be cut will form an auxiliary forward push for the already cut pipe material to ensure the auxiliary unloading of the cut pipe material. The unloading completed pipe material can be used as the middle straight cylinder part of the fire extinguisher tank body, and the top cap and bottom cap of the fire extinguisher tank body can be prepared and welded later through other external equipment.
