Description

Technical Field

[0001] The invention belongs to the technical field of metal welding, in particular to a metal product welding machine. Background Art

[0002] Welding is the process of connecting metal parts using various fusible alloys. The melting point of solder is lower than that of the material being welded, so the parts will be welded through the molecular contact on their surface without being melted, and welding ensures the continuity of the metal. It is manifested as a strong metal whole. The metal products industry includes structural metal products manufacturing, metal tool manufacturing, container and metal packaging container manufacturing, stainless steel and similar daily metal products manufacturing, etc. Metal products welding machine is a kind of equipment specially used for welding metal materials. It converts high-frequency electrical energy into mechanical vibration energy, so that high-frequency friction is generated between the workpieces, thereby generating heat between the surfaces of the workpieces and welding them together.

[0003] When metal products are being welded, they need to be fitted together with relevant fixing parts before hot-melt welding. When general desktop welding equipment uses the welding end to weld the workpiece at the bottom, the welding head will be lowered first to ensure that the welding head is in contact with the workpiece below before welding. At this time, the welding end will generate greater pressure on the workpiece. When the end sweeps over the joint of the workpiece, it will suffer obvious wear due to the large extrusion force, which will greatly increase the weld residue and affect the service life of the welding end. Therefore, improvements are needed. Summary of the invention

The bottom end of the deflection rod is rotatably connected to a sliding wheel, and the upper surface of the built-in sliding disk is fixedly connected to a pressure-sensitive pad cylinder through a connecting spring. When the sliding wheel at the bottom is subjected to an upward extrusion force, the built-in sliding disk will be pushed upward through the deflection rod, thereby triggering the pressure-sensitive pad cylinder to sense pressure.

When the guide slide bar slides down, the pressure on the pressure part of the pressure base caused by the buffer spring will gradually increase. At this time, the pressure base will remind the operator through the indicator light bar that gradually turns dark. The top of the guide slide bar is fixedly connected to the lower surface of the clamping inner plate, the left and right sides of the inner cavity of the fixed seat are plugged into the inner cavity of the connecting slider through the plug interface, and the inner wall of the fixed seat is slidably connected to the outer surface of the guide slide bar, and the bottom of the connecting slider is fixedly connected to the pressure surface of the upper surface of the pressure base through the buffer spring.

The compression floppy disk will be compressed.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When the welding equipment uses the welding end to weld the workpiece at the bottom, the welding head will be lowered first to ensure that the welding head is in contact with the workpiece below before welding. At this time, the welding end will generate greater pressure on the workpiece, and wear problems will affect the service life of the welding end. Before the welding end of the device contacts the metal block, it will contact the metal block in advance through the deflection rod of the outer ring, and dynamically adjust the distance between the welding end and the metal block during the welding process, thereby avoiding serious contact friction problems between the welding end and the metal block.

[0014] 2. As the metal block is rotating and turning over, the pressure of the deflection rod in contact with the metal block may change. At this time, the actual height of the welding end is dynamically adjusted through the welding limit mechanism according to the pressure change of the pressure-sensitive pad cylinder. That is, when the pressure of the pressure-sensitive pad cylinder increases, it means that the metal block is pushed upward. At this time, the welding end is pulled upward to avoid excessive contact pressure between the welding end and the metal block; when the pressure of the pressure-sensitive pad cylinder decreases, it means that the metal block is moving downward. At this time, the welding end is pushed downward to avoid separation of the welding end and the metal block, which makes it impossible to perform welding work.

[0015] 3. The welding limit mechanism drives the welding sleeve to slide downward by moving the fixed seat. At this time, the operator can directly observe the gradually deepening indicator light bar from the outside, and then appropriately slow down the work, so as to avoid the phenomenon that the welding end directly hits the suspended metal block, and prevent the clamped suspended metal block from being knocked off, resulting in the misalignment of the merged metal blocks.

[0016] 4. The pressure sensor acts as a transfer device, and can perform buffering work through the vertical elastic force of the buffer washers on the upper and lower sides, and the actual height of the compressed floppy disk can also be adjusted or compressed through the internal two-way push cylinder. Therefore, the actual height of the welding sleeve can be fine-tuned without using the welding limit mechanism to move the welding sleeve. In conjunction with the feedback of the pressure-sensitive pad cylinder, more sensitive debugging can be achieved when welding smaller metal blocks, making up for the shortcoming that the welding limit mechanism cannot be sensitively debugged.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 6 The present invention provides a technical solution: a metal product welding machine, comprising a frame 1, a guide component 2 is arranged at the top of the inner wall of the frame 1, a main welding component 3 is arranged at the axis of the guide component 2, and a limiting component 4 is arranged at the bottom of the frame 1;

[0028] The main welding component 3 includes a limiting guide plate 31, a buffer tympanum 32 is arranged at the axis center of the inner wall of the limiting guide plate 31, a welding connecting rod 33 is fixedly connected at the axis center of the inner cavity of the buffer tympanum 32, the welding connecting rod 33 slides along the buffer tympanum 32, and the buffer tympanum 32 can reduce the vibration and wear of the limiting guide plate 31 during movement, so as to run smoothly, a welding cylinder 34 is fixedly connected to the top of the welding connecting rod 33, a pressure sensor 5 is fixedly connected to the bottom end of the welding connecting rod 33, a fixing seat 35 is fixedly connected to the bottom end of the pressure sensor 5, and a welding component 6 is arranged at the axis center of the lower surface of the fixing seat 35;

[0029] The guide component 2 includes a clamping inner plate 21, the back of the upper surface of the clamping inner plate 21 is fixedly connected to a rear guide frame 22, the inner cavity of the rear guide frame 22 is rotatably connected to a welding limit mechanism 23, the bottom of the rear guide frame 22 is fixedly connected to a guide slider 24 through a connecting rod, and guide rails 25 are symmetrically arranged on the left and right sides of the outer surface of the guide slider 24. The welding limit mechanism 23 controls the rear guide frame 22 to drive the guide slider 24 below to pull the fixed seat 35 along the guide rail 25 for directional sliding movement, and the lower surface of the clamping inner plate 21 is symmetrically provided with a buffer component 7.

[0030] The welding component 6 includes a welding sleeve 61, a control wire 62 is fixedly connected to the axis of the inner cavity of the welding sleeve 61, and welding ends 63 are evenly arranged at the bottom of the welding sleeve 61. The welding sleeve 61 performs welding work through the welding ends 63 at the bottom, and each welding end 63 can slide downward relative to the welding sleeve 61 to align with different welding points. The outer surface of the welding sleeve 61 is fixedly connected to an external collar 64, and the inner cavity of the external collar 64 is evenly provided with guide slides 65. Both sides of each guide slide 65 are provided with penetrating side grooves. The inner wall of the guide slide 65 is slidably connected to a built-in sliding disk 66, and the lower surface of the built-in sliding disk 66 is fixed at the axis. It is fixedly connected with a deflection shaft 68, and a deflection rod 69 is fixedly connected to the outer surface of the deflection shaft 68. The deflection rod 69 is relatively thin and can pass through the side groove of the guide slide 65, so that the deflection rod 69 can be deflected outward along the outer surface of the deflection shaft 68, and can slide to the outside of the guide slide 65 through the side groove. The bottom end of the deflection rod 69 is rotatably connected with a sliding wheel 610, and the upper surface of the built-in sliding disk 66 is fixedly connected with a pressure-sensitive pad cylinder 67 through a connecting spring. When the sliding wheel 610 at the bottom is subjected to an upward extrusion force, the built-in sliding disk 66 will be pushed upward through the deflection rod 69, thereby triggering the pressure-sensitive pad cylinder 67 to sense pressure.

[0031] The top of the welding sleeve 61 is rotatably connected to the axis of the lower surface of the fixing seat 35 through the control shaft, the outer surface of the control wire 62 is slidably connected to the inner cavity of the fixing seat 35 through the through hole, and the top of the control wire 62 is fixedly connected to the bottom of the inner cavity of the welding cylinder 34. The outer surface of the clamping inner plate 21 is fixedly connected to the top of the inner wall of the frame 1, the front of the guide slider 24 is fixedly connected to the back of the outer surface of the fixing seat 35, the bottom of the guide slide rail 25 is fixedly connected to the inner wall of the frame 1 through the wall fixing plate 26, the bottom of the limit guide plate 31 is fixedly connected to the upper surface of the clamping inner plate 21, and the outer surface of the welding limit mechanism 23 is fixedly connected to the side of the frame 1.

[0032] The limiting component 4 includes a fixed bottom plate 41, a shading plate 42 is fixedly connected to the upper surface of the fixed bottom plate 41, an air suction machine 43 is symmetrically arranged on the front and rear sides of the inner wall of the shading plate 42, and a side controller 44 is symmetrically arranged on the left and right sides of the outer surface of the shading plate 42. The outer surface of the side controller 44 is fixedly connected to a fixed clamping plate 45 through a control rod. The side controllers 44 on both sides clamp the metal blocks to be welded by squeezing the fixed clamping plates 45 against each other, and are suspended at a certain height to ensure that when the side controller 44 twists the fixed clamping plates 45, the clamped metal blocks can be driven to rotate synchronously. There are two side controllers 44, the lower surface of the side controller 44 is fixedly connected to the upper surface of the fixed bottom plate 41, the bottom of the frame 1 is fixedly connected to the upper surface of the fixed bottom plate 41, and the outer surface of the air suction machine 43 is fixedly connected to the inner wall of the shading plate 42.

[0033] When using the device for welding, the two metal blocks are set in the bottom limiting component 4 for clamping and fixing, and then the operator controls the upper welding limiting mechanism 23, so that the bottom of the rear guide frame 22 slides the guide slider 24 and the fixed seat 35 downward along the guide rail 25 through the push rod. At this time, the welding connecting rod 33 slides downward relative to the welding cylinder 34, and the fixed seat 35 drives the welding component 6 below to approach the welding component 6 at the bottom.

[0034] Before welding, adjust the upper deflection rod 69 according to the width of the clamped metal block, that is, manually twist the deflection rod 69 so that the deflection rod 69 can slide relative to the outer surface of the deflection shaft 68, change the relative height of the sliding wheel 610 at the bottom of the deflection rod 69, and then insert the deflection rod 69 into the internal groove of the deflection shaft 68. At this time, the deflection rod 69 is fixed on the deflection shaft 68 at a specific angle, and itself may slide out through the side groove of the guide slide 65.

[0035] Before the welding end 63 is about to contact the welding metal block at the bottom, the deflection rod 69 located on the outside will first be squeezed with the upper surface of the metal block through the sliding wheel 610 at the bottom, and then the deflection rod 69 is subjected to the reaction force to push the built-in sliding plate 66 to slide up along the inner wall of the guide slide cylinder 65, and then trigger the pressure-sensitive pad cylinder 67 through pressure. At this time, the welding limit mechanism 23 needs to control the downward movement of the welding sleeve 61 at a relatively low speed until the indication of the pressure-sensitive pad cylinder 67 no longer changes. At this time, the welding end 63 has contacted the outer surface of the metal block, but it is not sure whether the extrusion force applied is too large, so the position of the welding sleeve 61 needs to be reversed to ensure that the welding end 63 is slightly in contact with the metal block without generating a large extrusion force.

[0036] When welding, the welding end 63 welds the welds of the metal blocks on both sides. Since the metal blocks are suspended and clamped by the fixed clamping plate 45, the fixed clamping plate 45 can move the metal blocks left and right and rotate the metal blocks during welding. Then, without moving the welding end 63, the welds are aligned with the welding end 63, and the toxic gases generated by welding are absorbed by the suction machines 43 on both sides.

[0037] When the metal block is rotating and turning over, the pressure of the deflection rod 69 in contact with the metal block may change. At this time, the actual height of the welding end 63 is dynamically adjusted through the welding limiting mechanism 23 according to the pressure change of the pressure-sensitive pad tube 67. That is, when the pressure of the pressure-sensitive pad tube 67 increases, it means that the metal block is pushed upward. At this time, the welding end 63 is pulled upward to avoid excessive contact pressure between the welding end 63 and the metal block; when the pressure of the pressure-sensitive pad tube 67 decreases, it means that the metal block is moving downward. At this time, the welding end 63 is pushed downward to avoid separation of the welding end 63 from the metal block, resulting in the inability to perform welding.

[0038] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the buffer component 7 includes a pressure base 71, the side of the pressure base 71 is fixedly connected with an indicator light bar 72, the upper surface of the pressure base 71 is evenly provided with a guide slide bar 73, the inner wall of the guide slide bar 73 is slidably connected with a connecting slider 74, and the upper and lower sides of the outer surface of the connecting slider 74 are symmetrically provided with a buffer spring 75. When the guide slide bar 73 slides down, the pressure on the pressure part of the pressure base 71 caused by the buffer spring 75 will gradually increase. At this time, the pressure base 71 will remind the operator through the indicator light bar 72 that gradually turns dark. The top of the guide slide bar 73 is fixedly connected to the lower surface of the clamping inner plate 21, the left and right sides of the inner cavity of the fixed seat 35 are plugged into the inner cavity of the connecting slider 74 through the plug interface, and the inner wall of the fixed seat 35 is slidably connected to the outer surface of the guide slide bar 73, and the bottom of the connecting slider 74 is fixedly connected to the pressure surface of the upper surface of the pressure base 71 through the buffer spring 75.

[0039] The pressure sensor 5 includes a compression disk 51, an axial sleeve 52 is slidably connected to the axis of the inner wall of the compression disk 51, and buffer washers 53 are symmetrically arranged on the upper and lower sides of the outer surface of the axial sleeve 52. A bidirectional push cylinder 54 is evenly arranged on the outer surface of the axial sleeve 52, and the end of the bidirectional push cylinder 54 shaft rod end close to the inner wall of the compression disk 51 is rotatably connected to the built-in pull sleeve 55, and the outer surface of the built-in pull sleeve 55 is fixedly connected to the inner cavity of the compression disk 51, and the upper surface of the compression disk 51 is connected to the inner cavity of the compression disk 51 through the upper buffer washer. 53 is fixedly connected to the bottom end of the welding connecting rod 33, and the lower surface of the compression disk 51 is fixedly connected to the upper surface of the fixing seat 35 through the lower buffer gasket 53. The actual height of the compression disk 51 can be increased by screwing the threaded push rods on both sides of the two-way push cylinder 54. When the two-way push cylinder 54 controls the threaded push rods to rotate clockwise, the threaded push rods will gradually slide out from the inside of the two-way push cylinder 54, and then the upper and lower sides of the compression disk 51 will be stretched by pushing the built-in pull sleeve 55, and vice versa, the compression disk 51 will be compressed.

[0040] The welding limit mechanism 23 drives the welding sleeve 61 to slide downward by moving the fixed seat 35. During this process, the guide slide rod 73 performs the guiding work, and the more the movable fixed seat 35 slides downward, the greater the pressure applied by the connecting slider 74 to the pressure base 71 through the buffer spring 75. At this time, the operator can directly observe the gradually deepening indicator light bar 72 from the outside, and then appropriately decelerate the work, thereby avoiding the phenomenon that the welding end 63 directly hits the suspended metal block.

[0041] The pressure sensor 5 plays a role of adapter, and can perform buffering work through the vertical elastic force of the buffer washers 53 on the upper and lower sides, and the actual height of the compressed floppy disk 51 can also be adjusted or compressed through the internal two-way push cylinder 54. Therefore, without using the welding limit mechanism 23 to move the welding sleeve 61, the actual height of the welding sleeve 61 can be fine-tuned. In conjunction with the feedback work of the pressure-sensitive pad cylinder 67, more sensitive debugging can be achieved when welding smaller metal blocks.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
