Description

Technical Field

[0001] The present invention belongs to the technical field of elliptical tank forming, and specifically relates to an elliptical tank forming device. Background Art

[0002] The elliptical tank of a water heater is a pressure regulating device installed between the cold and hot water pipes of the water heater. It is usually an elliptical metal container, mainly responsible for buffering the water pressure and stabilizing the operation of the system. Since the elliptical tank of the water heater bears cold and hot water for a long time inside, it is usually made of stainless steel. Special forming equipment is needed to assist the forming process during forming.

[0003] Conventional elliptical tanks are mainly formed by winding stainless steel plates, and end caps are welded to both ends of the cylinder to form a closed cylindrical elliptical tank. During the forming process, welding treatment needs to be carried out on the seams. When welding, usually after the wound elliptical tank is limited and fixed, welding is started to weld the seams. A complicated preparation process is required during the continuous welding process.

[0004] At the same time, after the elliptical tank completes the linear welding, the left and right end caps also need to be welded. In the prior art, different welding devices are needed to weld different positions respectively, and it is impossible to weld the linear weld and the circumferential weld simultaneously. The overall welding efficiency is low, and the versatility of the welding equipment is poor. Summary of the Invention

[0005] The purpose of the present invention is to provide an elliptical tank forming device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An elliptical tank forming device, including a machine base. An adjustment track is provided in the middle of the machine base. In the middle of the side of the machine base, a top frame located directly above the adjustment track is fixedly installed. In the middle of the bottom end of the top frame, a main cylinder is fixedly installed. The output end of the main cylinder is fixedly installed with a top movable frame. A linear guide groove is provided at the bottom end of the top movable frame. A linear welding assembly is movably clamped at the bottom end of the linear guide groove. An adjustment screw rod is threadedly sleeved in the middle of the linear welding assembly. On the left and right ends of the outer side of the adjustment screw rod, annular welding assemblies are movably sleeved. The annular welding assemblies are not threadedly sleeved with the adjustment screw rod. Adjustment assemblies are fixedly installed at the top ends of the annular welding assemblies. The two adjustment assemblies are symmetrically installed at positions near the left and right sides in the middle of the top movable frame. Clamping assemblies are installed on the front and rear sides in the middle of the top movable frame. The two clamping assemblies are symmetrically installed at positions on the front and rear sides of the adjustment track. Extension mounting seats are installed at the relatively far ends of the two annular welding assemblies.

[0007] Before forming the elliptical tank, the elliptical tank can be placed directly above the machine base, with the elliptical tank positioned between two clamping assemblies, and two annular welding assemblies located at both ends of the elliptical tank. Meanwhile, the elliptical tank needs to be in a suspended state before clamping, that is, it is held up until the clamping and limiting process is completed.

[0008] As a further technical solution of the present invention, the linear welding assembly includes a guiding block, which is movably clamped with the linear guiding groove. A passive telescopic rod is installed at the bottom end of the guiding block, and a guiding member is fixedly installed at the bottom end of the passive telescopic rod. A threaded groove is formed in the middle of the guiding member, and the guiding member is threadedly sleeved on the outer side of the adjusting screw rod through the threaded groove.

[0009] As a further technical solution of the present invention, a first micro-push rod is fixedly installed at the bottom end of the guiding member, a linear welding machine is fixedly installed at the output end of the first micro-push rod, and a linear grinding member is fixedly sleeved on the outer side of the linear welding machine.

[0010] When the clamping and limiting of the elliptical tank is completed and the linear weld needs to be welded, due to the upward displacement of the top movable frame, the passive telescopic rod is stretched as a whole at this time, and the guiding member maintains the current height. The length of the first micro-push rod can be adjusted according to the height of the elliptical tank from the linear welding machine until the linear welding machine reaches the welding height. At this time, the guiding member can be driven to linearly displace relative to the adjusting screw rod by using an external motor or manually rotating the adjusting screw rod, and cooperate with the welding of the linear welding machine to complete the linear welding process of the weld of the elliptical tank.

[0011] As a further technical solution of the present invention, the clamping assembly includes a fourth fixed seat, which is symmetrically installed at the front and rear ends of the top movable frame. One end of the fourth fixed seat away from the top movable frame is movably connected to a linkage rod through a rotating shaft, and one end of the linkage rod away from the fourth fixed seat is movably connected to a third fixed seat through a rotating shaft.

[0012] As a further technical solution of the present invention, locking members are fixedly installed at the bottom ends of the third fixed seats. Electric telescopic rods are fixedly installed at one ends of the two locking members close to each other. Clamping plates are installed at the output ends of the electric telescopic rods. The clamping plates are movably clamped with the adjusting track at the bottom end, and the clamping plates displace back and forth relative to the adjusting track.

[0013] Before welding preparation, the main cylinder can be activated to control its shortening. At this time, the top movable frame moves upward accordingly. When the top movable frame moves upward, the fourth fixed seat can be synchronously driven to move upward. At this time, the linkage rod deflects towards the middle accordingly and applies a thrust to the third fixed seat. At this time, the two clamping plates can approach relatively under the guiding action of the adjusting track. When the top movable frame moves upward to a predetermined position, the electric telescopic rod is activated to adjust the distance between the two clamping plates, so that the clamping plates are in contact with the outer side surface of the elliptical tank, completing the limiting clamping process of the elliptical tank, and continuously performing the straight welding process.

[0014] By utilizing the rising process of the top movable frame and the cooperation between the clamping component, the top movable frame and the straight welding component, while completing the positioning and preparation of the straight welding, the limiting fixation of the elliptical tank can be synchronously completed, and then the subsequent straight welding process can be quickly carried out. The entire welding process does not require a complicated preparation process. When batch welding elliptical tanks, a continuous welding process can be carried out, effectively improving the overall welding efficiency.

[0015] As a further technical solution of the present invention, the adjusting component includes a first fixed seat. The top end of the first fixed seat is connected to the bottom end of the top movable frame. One end of the first fixed seat away from the top movable frame is movably connected to a connecting rod through a rotating shaft, and one end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0016] As a further technical solution of the present invention, the adjusting component further includes a mounting member. The bottom end of the mounting member is connected to the top end of the annular welding component, and the front and rear sides of the top end of the mounting member are connected to the bottom end of the second fixed seat.

[0017] When the top movable frame moves upward, multiple first fixed seats move upward accordingly and drive multiple connecting rods to deflect. At this time, multiple connecting rods can deflect towards the middle and apply a thrust to the mounting member. At this time, the two mounting members approach relatively and drive the annular welding component at the bottom end to approach relatively.

[0018] As a further technical solution of the present invention, the annular welding component includes a movable member. The movable member is movably sleeved on the adjusting lead screw. A movable ring is installed at the bottom end of the movable member. One end of the two movable rings away from each other is connected to an extended mounting seat. An annular guiding groove is formed on the inner side surface of the movable ring. A motor is installed at one end of the extended mounting seat close to the movable ring, and a linkage frame is installed at the output end of the motor.

[0019] As a further technical solution of the present invention, the top end of the movable member is connected to the middle of the bottom end of the mounting member. On the side of the linkage frame away from the motor, annular guiding members are installed. The annular guiding members are movably clamped with the annular guiding grooves, and the annular guiding members rotate relative to the annular guiding grooves. At the bottom ends of the annular guiding members, second micro-push rods are fixedly installed.

[0020] As a further technical solution of the present invention, at the output ends of the second micro-push rods, circumferential welders are fixedly installed. On the outer sides of the circumferential welders, annular grinding members are fixedly sleeved.

[0021] When the two mounting members approach each other, at this time the two movable members move relative to the adjusting screw rod accordingly, and at the same time drive the two movable rings at the bottom ends to approach each other until the two movable rings are displaced to the end cover welding position of the elliptical tank. At this time, the top movable frame stops moving upward, completing the positioning of the end welding position. At the same time, the motor can be started to drive the annular guiding member to rotate circumferentially relative to the annular guiding groove, and the circumferential welding of the end of the elliptical tank can be completed through the circumferential welder, completing the end welding and the straight welding at the same time.

[0022] By making use of the upward displacement of the top movable frame again, while realizing the quick clamping and positioning of the elliptical tube, it can also realize the quick positioning of the end welding. The two are completed at the same time, and the circumferential welding of the end can be realized while the straight welding is carried out. There is no need for the complex step-by-step welding of the traditional device, and the overall welding process of the elliptical tank can be quickly realized. There is no need to use two devices for welding, and the overall welding of the elliptical tank can be quickly realized, shortening the welding time and improving the overall welding efficiency.

[0023] After the welding is completed, the first micro-push rod can be started at the same time to control the straight grinding member to descend until the straight grinding member contacts the straight weld, and the second micro-push rod is started to extend to control the annular grinding member to descend until it contacts the circumferential weld. Through the rotation of the motor, the circumferential rotation of the annular grinding member is realized, and through the rotation of the adjusting screw rod, the linear displacement of the straight grinding member is realized, completing the simultaneous grinding process of the straight weld and the circumferential weld, reducing the subsequent grinding process.

[0024] By making use of the straight welding and circumferential welding processes again, through the cooperation between the straight welding assembly and the annular welding assembly, after the overall welding of the elliptical tank is completed, the weld can be quickly ground. The entire grinding process can be quickly completed after the welding is finished, reducing the subsequent grinding process and significantly improving the overall forming quality of the elliptical tank.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) By utilizing the ascending process of the top movable frame and the cooperative action among the clamping assembly, the top movable frame, and the linear welding assembly, the present invention can complete the positioning and preparation for linear welding while simultaneously completing the limit fixation of the elliptical tank, enabling the subsequent linear welding process to be carried out rapidly. The entire welding process does not require a complicated preparation process. During the batch welding of elliptical tanks, a continuous welding process can be carried out, effectively improving the overall welding efficiency.

[0027] (2) By reusing the upward displacement of the top movable frame, the present invention can achieve the rapid clamping and positioning of the elliptical pipe while also achieving the rapid positioning of the end welding. Both are completed simultaneously, and the circumferential welding of the end can be achieved while performing linear welding. It does not require the complicated step-by-step welding of traditional devices, can rapidly complete the overall welding process of the elliptical tank, does not require the use of two devices for welding, can rapidly complete the overall welding of the elliptical tank, shorten the welding time, and improve the overall welding efficiency.

[0028] (3) By reusing the linear welding and circumferential welding processes and through the cooperative action between the linear welding assembly and the annular welding assembly, the present invention can rapidly perform a grinding operation on the weld seam after completing the overall welding of the elliptical tank. The entire grinding process can be rapidly completed after welding, reducing the subsequent grinding process and significantly improving the overall forming quality of the elliptical tank.

Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] As Figures 1 to 8 shown, in the embodiment of the present invention, the elliptical tank forming device includes a base 1. An adjustment track 2 is provided in the middle of the base 1. In the middle of the side of the base 1, a top frame 3 located directly above the adjustment track 2 is fixedly installed. In the middle of the bottom end of the top frame 3, a main cylinder 4 is fixedly installed. The output end of the main cylinder 4 is fixedly installed with a top movable frame 5. A linear guide groove 6 is provided at the bottom end of the top movable frame 5. At the bottom end of the linear guide groove 6, a linear welding assembly 7 is movably clamped. The middle of the linear welding assembly 7 is threadedly sleeved with an adjustment screw rod 8. On the left and right ends of the outer side of the adjustment screw rod 8, annular welding assemblies 11 are movably sleeved. The annular welding assemblies 11 are not threadedly sleeved with the adjustment screw rod 8. At the top ends of the annular welding assemblies 11, adjustment assemblies 9 are fixedly installed. The two adjustment assemblies 9 are symmetrically installed at positions near the left and right sides in the middle of the top movable frame 5. On the front and rear sides of the middle of the top movable frame 5, clamping assemblies 12 are installed. The two clamping assemblies 12 are symmetrically installed at positions on the front and rear sides of the adjustment track 2. At the relatively far ends of the two annular welding assemblies 11 away from each other, extended mounting seats 10 are installed.

[0040] Before forming the elliptical tank, the elliptical tank can be placed directly above the machine base 1, with the elliptical tank held between the two clamping components 12, and the two annular welding components 11 located at both ends of the elliptical tank. At the same time, before clamping, the elliptical tank needs to be in a suspended state, that is, the elliptical tank is held up until the clamping and limiting process is completed.

[0041] As Figure 1 and Figure 5 shown, the linear welding component 7 includes a guide block 701, which is movably clamped with the linear guide groove 6. A passive telescopic rod 702 is installed at the bottom end of the guide block 701. A guide member 703 is fixedly installed at the bottom end of the passive telescopic rod 702. A threaded groove 704 is provided in the middle of the guide member 703. The guide member 703 is threadedly sleeved on the outer side of the adjusting screw rod 8 through the threaded groove 704. A first micro-pusher 705 is fixedly installed at the bottom end of the guide member 703. A linear welding machine 706 is fixedly installed at the output end of the first micro-pusher 705. A linear grinding member 707 is fixedly sleeved on the outer side of the linear welding machine 706.

[0042] When the clamping and limiting of the elliptical tank is completed and the linear weld needs to be welded, due to the upward displacement of the top movable frame 5, at this time, the passive telescopic rod 702 is stretched as a whole, and the guide member 703 maintains the current height, and the length of the first micro-pusher 705 can be adjusted according to the height of the elliptical tank from the linear welding machine 706 until the linear welding machine 706 reaches the welding height. At this time, the external motor or manually rotating the adjusting screw rod 8 can be used to drive the linear displacement of the guide member 703 relative to the adjusting screw rod 8, and cooperate with the welding of the linear welding machine 706 to complete the linear welding process of the weld of the elliptical tank.

[0043] As Figure 1 and Figure 6 and Figure 8 shown, the clamping component 12 includes a fourth fixed seat 125, which is symmetrically installed at the front and rear ends of the top movable frame 5. One end of the fourth fixed seat 125 away from the top movable frame 5 is movably connected to a linkage rod 126 through a rotating shaft. One end of the linkage rod 126 away from the fourth fixed seat 125 is movably connected to a third fixed seat 124 through a rotating shaft. Locking members 123 are fixedly installed at the bottom ends of the third fixed seats 124. Electric telescopic rods 122 are fixedly installed at the relatively close ends of the two locking members 123. Clamping plates 121 are installed at the output ends of the electric telescopic rods 122. The clamping plates 121 are movably clamped with the adjusting track 2 at the bottom end, and the clamping plates 121 move back and forth relative to the adjusting track 2.

[0044] Embodiment: Before welding preparation, the main cylinder 4 can be activated to control its shortening. At this time, the top movable frame 5 moves upward accordingly. When the top movable frame 5 moves upward, the fourth fixed seat 125 can be driven to move upward synchronously. At this time, the linkage rod 126 deflects toward the middle accordingly and applies a thrust to the third fixed seat 124. At this time, the two clamping plates 121 can move relatively closer under the guiding action of the adjustment track 2. When the top movable frame 5 moves upward to a predetermined position, the electric telescopic rod 122 is activated to adjust the distance between the two clamping plates 121 so that the clamping plates 121 are in contact with the outer side of the elliptical tank, completing the limiting clamping process of the elliptical tank and continuously performing the straight-line welding process.

[0045] By utilizing the rising process of the top movable frame 5 and the cooperative action between the clamping assembly 12, the top movable frame 5, and the straight-line welding assembly 7, while completing the positioning and preparation of the straight-line welding, the limiting fixation of the elliptical tank can be synchronously completed, and then the subsequent straight-line welding process can be quickly carried out. The entire welding process does not require a complicated preparation process. When batch-welding elliptical tanks, a continuous welding process can be carried out, effectively improving the overall welding efficiency.

[0046] As Figure 1 and Figure 7 shown, the adjustment assembly 9 includes a first fixed seat 901. The top end of the first fixed seat 901 is connected to the bottom end of the top movable frame 5. One end of the first fixed seat 901 away from the top movable frame 5 is movably connected to a connecting rod 904 through a rotating shaft. One end of the connecting rod 904 away from the first fixed seat 901 is movably connected to a second fixed seat 902 through a rotating shaft. The adjustment assembly 9 further includes a mounting member 903. The bottom end of the mounting member 903 is connected to the top end of the annular welding assembly 11. The front and rear sides of the top end of the mounting member 903 are connected to the bottom end of the second fixed seat 902.

[0047] When the top movable frame 5 moves upward, at this time, the plurality of first fixed seats 901 move upward accordingly and drive the plurality of connecting rods 904 to deflect. At this time, the plurality of connecting rods 904 can deflect toward the middle and apply a thrust to the mounting member 903. At this time, the two mounting members 903 move relatively closer and drive the annular welding assembly 11 at the bottom to move relatively closer.

[0048] As Figure 1 and Figure 6 and Figure 8As shown, the annular welding assembly 11 includes a movable part 111, which is movably sleeved with the adjusting screw rod 8. An movable ring 112 is installed at the bottom end of the movable part 111. One end of the two movable rings 112 facing away from each other is connected to the extended mounting base 10. An annular guiding groove 113 is formed on the inner side surface of the movable ring 112. A motor 118 is installed at one end of the extended mounting base 10 close to the movable ring 112. A linkage frame 119 is installed at the output end of the motor 118. The top end of the movable part 111 is connected to the middle part of the bottom end of the mounting part 903. Annular guiding members 114 are installed on one side of the linkage frame 119 away from the motor 118. The annular guiding members 114 are movably clamped with the annular guiding groove 113. The annular guiding members 114 rotate relative to the annular guiding groove 113. Second micro-push rods 115 are fixedly installed at the bottom ends of the annular guiding members 114. Circumferential welding machines 116 are fixedly installed at the output ends of the second micro-push rods 115. Annular grinding members 117 are fixedly sleeved on the outer side surfaces of the circumferential welding machines 116.

[0049] Embodiment: When the two mounting parts 903 approach each other, at this time, the two movable parts 111 displace relative to the adjusting screw rod 8 accordingly, and at the same time drive the two movable rings 112 at the bottom ends to approach each other until the two movable rings 112 are displaced to the end cover welding position of the elliptical tank. At this time, the top movable frame 5 stops moving upward, completing the positioning of the end welding position. At the same time, the motor 118 can be started to drive the annular guiding member 114 to rotate circumferentially relative to the annular guiding groove 113, and the circumferential welding machine 116 is used to complete the welding process of the end of the elliptical tank, completing the end welding and the straight welding at the same time.

[0050] By reusing the upward displacement of the top movable frame 5, while realizing the quick clamping and positioning of the elliptical pipe, it can also realize the quick positioning of the end welding. The two are completed at the same time, and the circumferential welding of the end can be realized while the straight welding is carried out. There is no need for the complex step-by-step welding of the traditional device, and the overall welding process of the elliptical tank can be quickly realized. There is no need to use two devices for welding, and the overall welding of the elliptical tank can be quickly realized, shortening the welding time and improving the overall welding efficiency.

[0051] After the welding is completed, the first micro-push rod 705 can be started at the same time to control the straight grinding member 707 to descend until the straight grinding member 707 contacts the straight weld, and the second micro-push rod 115 is started to extend to control the annular grinding member 117 to descend until it contacts the circumferential weld. Through the rotation of the motor 118, the circumferential rotation of the annular grinding member 117 is realized, and through the rotation of the adjusting screw rod 8, the linear displacement of the straight grinding member 707 is realized, completing the simultaneous grinding process of the straight weld and the circumferential weld, reducing the subsequent grinding process.

[0052] By reusing the straight-line welding and circumferential welding processes, through the cooperation between the straight-line welding assembly 7 and the annular welding assembly 11, the welds can be quickly ground after the overall welding of the elliptical tank is completed. The entire grinding process can be quickly completed after welding, reducing subsequent grinding processes and significantly improving the overall forming quality of the elliptical tank.

[0053] Working principle and usage process:

[0054] Before forming the elliptical tank, the elliptical tank can be placed directly above the machine base 1, keeping the elliptical tank between the two clamping assemblies 12, and the two annular welding assemblies 11 at both ends of the elliptical tank. At the same time, the elliptical tank needs to be in a suspended state before clamping, that is, keep lifting the elliptical tank until the clamping and limiting process is completed;

[0055] Before welding preparation, the main cylinder 4 can be activated to control it to shorten. At this time, the top movable frame 5 moves upward accordingly. When the top movable frame 5 moves upward, it can synchronously drive the fourth fixed seat 125 to move upward. At this time, the linkage rod 126 deflects toward the middle accordingly and exerts a thrust on the third fixed seat 124. At this time, the two clamping plates 121 can approach each other relatively under the guiding action of the adjustment track 2. When the top movable frame 5 moves upward to a predetermined position, the electric telescopic rod 122 is activated to adjust the distance between the two clamping plates 121 so that the clamping plates 121 are in contact with the outer side of the elliptical tank, completing the limiting clamping process of the elliptical tank and continuously performing the straight-line welding process;

[0056] When the clamping and limiting of the elliptical tank are completed and the straight weld needs to be welded, due to the upward displacement of the top movable frame 5, the passive telescopic rod 702 is stretched as a whole at this time, and the guide member 703 maintains the current height and can adjust the length of the first micro-push rod 705 according to the height of the elliptical tank from the straight-line welding machine 706 until the straight-line welding machine 706 reaches the welding height. At this time, the external motor or manual rotation of the adjustment screw rod 8 can be used to drive the guide member 703 to linearly displace relative to the adjustment screw rod 8 and cooperate with the welding of the straight-line welding machine 706 to complete the straight-line welding process of the weld of the elliptical tank;

[0057] When the top movable frame 5 moves upward, at this time, multiple first fixed seats 901 move upward accordingly and drive multiple connecting rods 904 to deflect. At this time, multiple connecting rods 904 can deflect toward the middle and exert a thrust on the mounting member 903. At this time, the two mounting members 903 approach each other relatively and drive the annular welding assembly 11 at the bottom to approach each other relatively;

[0058] When the two mounting members 903 approach each other, the two movable members 111 are displaced relative to the adjusting screw rod 8 accordingly. At the same time, the two movable rings 112 at the bottom are driven to approach each other until the two movable rings 112 are displaced to the end cap welding position of the elliptical tank. At this time, the top movable frame 5 stops moving upward, completing the positioning of the end welding position. Meanwhile, the motor 118 can be started to drive the annular guide member 114 to rotate circumferentially relative to the annular guide groove 113, and the circumferential welding machine 116 is used to complete the welding process of the end of the elliptical tank, completing the end welding and the straight welding simultaneously.

[0059] After the welding is completed, the first micro-push rod 705 can be started simultaneously to control the straight grinding member 707 to descend until the straight grinding member 707 contacts the straight weld. And the second micro-push rod 115 is started to extend to control the annular grinding member 117 to descend until it contacts the circumferential weld. Through the rotation of the motor 118, the circumferential rotation of the annular grinding member 117 is realized, and through the rotation of the adjusting screw rod 8, the linear displacement of the straight grinding member 707 is realized, completing the simultaneous grinding process of the straight weld and the circumferential weld, reducing the subsequent grinding process.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
