Description

Technical Field

[0001] The invention belongs to the technical field of elliptical can forming, in particular to elliptical can forming equipment. Background Art

[0002] The oval tank of a water heater is a pressure regulating device installed between the hot and cold water pipes of the water heater. It is usually an oval metal container. Its main function is to buffer the water pressure and stabilize the operation of the system. The oval tank of a water heater is often made of stainless steel because it carries hot and cold water for a long time. Special molding equipment is required to assist the molding process.

[0003] Conventional elliptical cans are mainly formed by winding stainless steel plates, and end covers are welded at both ends of the cylinder to form a closed cylindrical elliptical can. During the forming process, the seams need to be welded. During welding, it is usually necessary to limit and fix the elliptical can after winding, and then start welding to weld the seams. A complicated preparation process is required in the continuous welding process.

[0004] At the same time, after completing the linear welding of the elliptical tank, the left and right end covers also need to be welded. In the prior art, different welding devices need to be used to weld different positions respectively, and it is impossible to achieve simultaneous welding of linear welds and circular welds. The overall welding efficiency is low, and the versatility of the welding equipment is poor. Summary of the invention

[0005] The object of the present invention is to provide an oval can forming device to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: an elliptical can forming equipment comprises a machine base, an adjusting track is provided in the middle of the machine base, a top frame located directly above the adjusting track is fixedly installed in the middle of the side surface of the machine base, a main cylinder is fixedly installed in the middle of the bottom end of the top frame, a top movable frame is fixedly installed at the output end of the main cylinder, 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 adjusting screw is threadedly sleeved at the middle of the linear welding assembly, an annular welding assembly is movably sleeved at the left and right ends of the outer side surface of the adjusting screw, the annular welding assembly is not threadedly sleeved with the adjusting screw, an adjusting assembly is fixedly installed at the top end of the annular welding assembly, two adjusting assemblies are symmetrically installed at the middle part of the top movable frame near the left and right sides, clamping assemblies are installed at the front and back sides of the middle part of the top movable frame, two clamping assemblies are symmetrically installed at the front and back sides of the adjusting track, and an extended mounting seat is installed at the relatively far ends of the two annular welding assemblies.

[0007] Before forming the elliptical can, the elliptical can can be placed directly above the machine base, keeping the elliptical can between the two clamping components, and the two annular welding components at both ends of the elliptical can. At the same time, the elliptical can must be kept in a suspended state before clamping, that is, the elliptical can must be kept lifted until the clamping and limiting process is completed.

[0008] As a further technical solution of the present invention, the linear welding assembly includes a guide block, which is movably connected to the linear guide groove, a passive telescopic rod is installed at the bottom end of the guide block, a guide piece is fixedly installed at the bottom end of the passive telescopic rod, a threaded groove is opened in the middle of the guide piece, and the guide piece is threadedly sleeved with the outer side surface of the adjusting screw through the threaded groove.

[0009] As a further technical solution of the present invention, a first micro push rod is fixedly installed on the bottom end of the guide member, a linear welder is fixedly installed on the output end of the first micro push rod, and a linear grinding piece is fixedly sleeved on the outer side surface of the linear welder.

[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 lengthened as a whole, and the guide 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 welder until the linear welder reaches the welding height. At this time, an external motor or manual rotation of the adjusting screw can be used to drive the guide to move linearly relative to the adjusting screw, and cooperate with the welding of the linear welder to complete the linear welding process of the elliptical tank weld.

[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, and the end of the fourth fixed seat away from the top movable frame is movably connected to a linkage rod through a rotating shaft, and the end of the linkage rod away from the fourth fixed seat is movably connected to the third fixed seat through a rotating shaft.

[0012] As a further technical solution of the present invention, a locking piece is fixedly installed at the bottom end of the third fixed seat, and an electric telescopic rod is fixedly installed at one end of the two locking pieces that are relatively close to each other, and a clamping plate is installed at the output end of the electric telescopic rod, and the clamping plate is movably connected to the adjustment track at the bottom, and the clamping plate moves forward and backward relative to the adjustment track.

[0013] Before welding preparation, the main cylinder can be turned on to control its shortening. At this time, the top movable frame will move up accordingly. When the top movable frame moves up, the fourth fixed seat can be driven up synchronously. At this time, the linkage rod will deflect toward the middle and apply thrust to the third fixed seat. At this time, the two clamps can be relatively close to each other under the guidance of the adjustment track. When the top movable frame moves to the predetermined position, the electric telescopic rod is turned on to adjust the distance between the two clamps so that the clamps are in contact with the outer side of the elliptical tank, completing the limit clamping process of the elliptical tank and continuously performing the linear welding process.

[0014] By utilizing the rising process of the top movable frame and the cooperation between the clamping assembly, the top movable frame and the linear welding assembly, the positioning and preparation of the linear welding can be completed while the limiting fixation of the elliptical tank can be completed simultaneously, so that the subsequent linear welding process can be carried out quickly. The entire welding process does not require complicated preparation processes. When performing batch welding of elliptical tanks, a continuous welding process can be carried out, which effectively improves the overall welding efficiency.

[0015] As a further technical solution of the present invention, the adjustment assembly includes a first fixed seat, the top end of the first fixed seat is connected to the bottom end of the top movable frame, the end of the first fixed seat away from the top movable frame is movably connected to a connecting rod via a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft.

[0016] As a further technical solution of the present invention, the adjustment assembly also includes a mounting member, the bottom end of the mounting member is connected to the top end of the annular welding assembly, and the front and rear sides of the top end of the mounting member are connected to the bottom end of the second fixing 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 toward the middle and apply thrust to the mounting parts. At this time, the two mounting parts are relatively close to each other and drive the annular welding assembly at the bottom to be relatively close.

[0018] As a further technical solution of the present invention, the annular welding assembly includes a movable part, which is movably connected to the adjusting screw rod, and a movable ring is installed at the bottom end of the movable part. The relatively distant ends of the two movable rings are connected to the extended mounting seat, and an annular guide groove is provided on the inner side 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 of the movable part is connected to the middle part of the bottom end of the mounting part, and an annular guide part is installed on the side of the linkage frame away from the motor. The annular guide part is movably connected to the annular guide groove, and the annular guide part rotates relative to the annular guide groove. A second micro push rod is fixedly installed on the bottom end of the annular guide part.

[0021] When the two mounting parts are close to each other, the two movable parts adjust the displacement of the screw rod relatively, and at the same time drive the two movable rings at the bottom to be relatively close, until the two movable rings are moved 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, and at the same time, the motor can be turned on to drive the annular guide to rotate circumferentially relative to the annular guide groove, and complete the welding process of the end of the elliptical tank through the circular welder, completing the end welding and linear welding at the same time.

[0022] By reusing the upward displacement of the top movable frame, it can realize the rapid clamping and positioning of the elliptical tube and the rapid positioning of the end welding. The two can be completed at the same time, and the circumferential welding of the end can be achieved at the same time as the linear welding. There is no need for the complicated step-by-step welding of traditional devices, 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, thereby shortening the welding time and improving the overall welding efficiency.

[0023] After welding is completed, the first micro push rod can be turned on at the same time to control the linear grinding part to descend until the linear grinding part contacts the linear weld, and the second micro push rod can be turned on to extend to control the annular grinding part to descend until it contacts the circumferential weld. The annular grinding part can be rotated in a circular manner by rotating the motor, and the linear displacement of the linear grinding part can be achieved by adjusting the rotation of the lead screw, thereby completing the simultaneous grinding process of the linear weld and the circumferential weld, reducing the subsequent grinding process.

[0024] By reusing the linear welding and circular welding processes, and through the cooperation between the linear welding components and the annular welding components, the weld can be quickly polished after the overall welding of the elliptical tank is completed. The entire polishing process can be completed quickly after the welding is completed, reducing the subsequent polishing process and significantly improving the overall molding quality of the elliptical tank.

[0025] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the rising process of the top movable frame and the cooperation between the clamping assembly, the top movable frame and the linear welding assembly to complete the positioning and preparation of the linear welding while simultaneously completing the limiting fixation of the elliptical tank, so that the subsequent linear welding process can be quickly carried out. The entire welding process does not require a complicated preparation process. When performing batch welding of elliptical tanks, a continuous welding process can be carried out, effectively improving the overall welding efficiency.

[0026] (2) The present invention reuses the upward displacement of the top movable frame to achieve rapid clamping and positioning of the elliptical tube and rapid positioning of the end welding. The two are completed at the same time, and the circular welding of the end can be achieved at the same time as the linear welding. There is no need for the complicated step-by-step welding of the traditional device, and the overall welding process of the elliptical tank can be quickly achieved. There is no need to use two devices for welding, and the overall welding of the elliptical tank can be quickly achieved, thereby shortening the welding time and improving the overall welding efficiency.

[0027] (3) The present invention reuses the linear welding and circular welding processes. Through the cooperation between the linear welding assembly and the circular welding assembly, the weld can be quickly polished after the overall welding of the elliptical tank is completed. The entire polishing process can be completed quickly after the welding is completed, reducing the subsequent polishing process and significantly improving the overall molding quality of the elliptical tank.

[0032] Before forming the elliptical can, the elliptical can can be placed directly above the machine base 1, keeping the elliptical can between the two clamping components 12, and the two annular welding components 11 at both ends of the elliptical can. At the same time, the elliptical can needs to be kept in a suspended state before clamping, that is, the elliptical can is kept lifted until the clamping and limiting process is completed.

[0033] like Figure 1 and Figure 5 As shown, the linear welding assembly 7 includes a guide block 701, which is movably connected 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 opened in the middle of the guide member 703, the guide member 703 is threadedly sleeved with the outer side surface of the adjusting screw 8 through the threaded groove 704, a first micro push rod 705 is fixedly installed at the bottom end of the guide member 703, a linear welder 706 is fixedly installed at the output end of the first micro push rod 705, and a linear grinding member 707 is fixedly sleeved on the outer side surface of the linear welder 706.

[0035] like Figure 1 and Figure 6 as well as Figure 8 As shown, the clamping assembly 12 includes a fourth fixed seat 125, and the fourth fixed seat 125 is symmetrically installed at the front and rear ends of the top movable frame 5. The end of the fourth fixed seat 125 away from the top movable frame 5 is movably connected with a linkage rod 126 through a rotating shaft, and the end of the linkage rod 126 away from the fourth fixed seat 125 is movably connected with a third fixed seat 124 through a rotating shaft.

[0036] Embodiment: Before welding preparation, the main cylinder 4 can be turned on to control its shortening. At this time, the top movable frame 5 moves up accordingly. When the top movable frame 5 moves up, the fourth fixed seat 125 can be driven to move up synchronously. At this time, the linkage rod 126 deflects toward the middle and applies a thrust to the third fixed seat 124. At this time, the two splints 121 can be relatively close to each other under the guidance of the adjustment track 2. When the top movable frame 5 moves to a predetermined position, the electric telescopic rod 122 is turned on to adjust the distance between the two splints 121, so that the splints 121 are in contact with the outer side of the elliptical tank, completing the limit clamping process of the elliptical tank, and continuously performing the linear welding process.

[0037] By utilizing the rising process of the top movable frame 5 and the cooperation between the clamping assembly 12, the top movable frame 5 and the linear welding assembly 7, the positioning and preparation for linear welding can be completed while the limiting fixation of the elliptical tank can be completed simultaneously, so that the subsequent linear welding process can be carried out quickly. The entire welding process does not require complicated preparation processes. When performing batch welding of elliptical tanks, a continuous welding process can be carried out, effectively improving the overall welding efficiency.

[0038] like Figure 1 and Figure 7 As shown, the adjustment component 9 includes a first fixed seat 901, the top of the first fixed seat 901 is connected to the bottom end of the top movable frame 5, the 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, and the 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 component 9 also includes a mounting member 903, the bottom end of the mounting member 903 is connected to the top of the annular welding assembly 11, and the front and rear sides of the top of the mounting member 903 are connected to the bottom end of the second fixed seat 902.

[0039] When the top movable frame 5 moves upward, the multiple first fixed seats 901 move upward accordingly, and drive the multiple connecting rods 904 to deflect. At this time, the multiple connecting rods 904 can deflect toward the middle and apply thrust to the mounting parts 903. At this time, the two mounting parts 903 are relatively close to each other and drive the annular welding assembly 11 at the bottom to be relatively close.

[0040] like Figure 1 and Figure 6 as well as Figure 8As shown, the annular welding assembly 11 includes a movable part 111, which is movably sleeved with the adjusting screw rod 8. A movable ring 112 is installed at the bottom end of the movable part 111. The ends of the two movable rings 112 that are relatively far away are connected to the extended mounting seat 10. An annular guide groove 113 is opened on the inner side of the movable ring 112. A motor 118 is installed at the end of the extended mounting seat 10 close to the movable ring 112. A linkage frame 119 is installed at the output end of the motor 118. The top of the movable part 111 is connected to the mounting seat 10. The middle part of the bottom end of the member 903 is connected, and an annular guide member 114 is installed on the side of the linkage frame 119 away from the motor 118. The annular guide member 114 is movably connected with the annular guide groove 113, and the annular guide member 114 rotates relative to the annular guide groove 113. The bottom end of the annular guide member 114 is fixedly installed with a second micro push rod 115, and the output end of the second micro push rod 115 is fixedly installed with a circumferential welder 116, and the outer side surface of the circumferential welder 116 is fixedly sleeved with an annular grinding member 117.

[0041] Embodiment: When the two mounting parts 903 are close to each other, the two movable parts 111 are moved relative to the adjusting screw rod 8, and at the same time, the two movable rings 112 at the bottom are driven to move relatively close, until the two movable rings 112 are moved to the end cover welding position of the elliptical tank. At this time, the top movable frame 5 stops moving upward, and the positioning of the end welding position is completed. At the same time, the motor 118 can be turned on to drive the annular guide part 114 to rotate circumferentially relative to the annular guide groove 113, and the welding process of the end of the elliptical tank is completed through the circular welder 116, and the end welding and linear welding are completed at the same time.

[0042] By reusing the upward displacement of the top movable frame 5, it can realize the rapid clamping and positioning of the elliptical tube and the rapid positioning of the end welding. The two are completed at the same time, and the circular welding of the end can be realized at the same time as the linear welding. There is no need for the complicated step-by-step welding of the traditional device, and the overall welding process of the elliptical tank can be realized quickly. There is no need to use two devices for welding, and the overall welding of the elliptical tank can be realized quickly, thereby shortening the welding time and improving the overall welding efficiency.

[0043] After welding is completed, the first micro push rod 705 can be turned on at the same time to control the linear grinding part 707 to descend until the linear grinding part 707 contacts the linear weld, and the second micro push rod 115 can be turned on to extend and control the annular grinding part 117 to descend until it contacts the circumferential weld. The annular grinding part 117 can be rotated in a circle by rotating the motor 118, and the rotation of the screw rod 8 can be adjusted to realize the linear displacement of the linear grinding part 707, thereby completing the simultaneous grinding process of the linear weld and the circumferential weld, and reducing the subsequent grinding process.

[0044] By reusing the linear welding and circular welding processes, and through the cooperation between the linear welding component 7 and the annular welding component 11, the weld can be quickly polished after the overall welding of the elliptical tank is completed. The entire polishing process can be completed quickly after the welding is completed, reducing the subsequent polishing process and significantly improving the overall molding quality of the elliptical tank.

[0045] Working principle and usage process: Before forming the elliptical can, the elliptical can can be placed directly above the machine base 1, and the elliptical can is kept between the two clamping components 12, and the two annular welding components 11 are located at both ends of the elliptical can. At the same time, the elliptical can needs to be kept in a suspended state before clamping, that is, the elliptical can is kept lifted until the clamping and limiting process is completed; Before welding preparation, the main cylinder 4 can be turned on to control its shortening, and the top movable frame 5 moves up accordingly. When the top movable frame 5 moves up, the fourth fixed seat 125 can be synchronously driven to move up. At this time, the linkage rod 126 deflects toward the middle and applies thrust to the third fixed seat 124. At this time, the two clamping plates 121 can be relatively close to each other under the guidance of the adjustment track 2. When the top movable frame 5 moves up to the predetermined position, the electric telescopic rod 122 is turned on 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 limit clamping process of the elliptical tank, and continuously performing the linear welding process; When the clamping limit 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, 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 push rod 705 can be adjusted according to the height of the elliptical tank from the linear welder 706 until the linear welder 706 reaches the welding height. At this time, the guide member 703 can be driven to move linearly relative to the adjusting screw rod 8 by using an external motor or manually rotating the adjusting screw rod 8, and cooperate with the welding of the linear welder 706 to complete the linear welding process of the elliptical tank weld; When the top movable frame 5 moves upward, the multiple first fixing seats 901 move upward accordingly, and drive the multiple connecting rods 904 to deflect. At this time, the multiple connecting rods 904 can deflect toward the middle and apply thrust to the mounting member 903. At this time, the two mounting members 903 are relatively close to each other, and drive the annular welding assembly 11 at the bottom to be relatively close to each other; When the two mounting parts 903 are close to each other, the two movable parts 111 are relatively adjusted to move the screw rod 8, and at the same time, the two movable rings 112 at the bottom are relatively close, until the two movable rings 112 are moved to the end cover welding position of the elliptical tank, and the top movable frame 5 stops moving upward, and the end welding position is positioned, and the motor 118 can be turned on to drive the annular guide 114 to rotate circumferentially relative to the annular guide groove 113, and the circumferential welder 116 is used to complete the welding process of the end of the elliptical tank, and the end welding and linear welding are completed at the same time; After welding is completed, the first micro push rod 705 can be turned on at the same time to control the linear grinding part 707 to descend until the linear grinding part 707 contacts the linear weld, and the second micro push rod 115 can be turned on to extend and control the annular grinding part 117 to descend until it contacts the circumferential weld. The annular grinding part 117 can be rotated in a circle by rotating the motor 118, and the rotation of the screw rod 8 can be adjusted to realize the linear displacement of the linear grinding part 707, thereby completing the simultaneous grinding process of the linear weld and the circumferential weld, and reducing the subsequent grinding process.
