Description

Technical Field

[0001] The utility model relates to the technical field of pick processing, in particular to a welding device for mining pick processing. Background Art

[0002] In mining fields such as coal mining, mining picks are important tools, and their quality and production efficiency have an important impact on mining production. The core of pick welding is to firmly connect a high-hardness cemented carbide cutting head to a high-strength steel matrix through a brazing process to form a composite structure of "hard edge + strong body" to meet the requirements of high wear resistance and impact resistance in cutting operations.

[0003] Existing conveying devices are difficult to achieve synchronous conveying of picks at equal time intervals and equal distances. The commonly used conveyor belt conveying method is prone to unstable speed and inaccurate positioning during the conveying process, resulting in position deviation of the picks during the welding process and affecting the consistency of welding quality. Moreover, due to the inability to precisely control the conveying interval, the distance between adjacent picks may be unreasonable, affecting the smooth progress of the welding operation and reducing the production efficiency. There is a lack of effective coordination and cooperation between various parts of the existing device, and links such as conveying, heating, and solder addition cannot be well synchronized, resulting in poor coherence and coordination of the entire welding process, further reducing the production efficiency and product quality. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is the insufficient positioning accuracy during the pick conveying process, uneven conveying intervals, and the inability to effectively synchronize links such as conveying, heating, and solder addition, which reduce the production efficiency and product quality.

Detailed Description of the Preferred Embodiment

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a welding device for processing mining picks, the main body of which includes a workbench 1. A conveying mechanism and an output mechanism are respectively arranged on the left and right sides of the workbench 1. The conveying mechanism is used to convey the picks 3 to be welded to the working area, and the output mechanism is used to remove the welded picks 3.

[0030] A combined welding support 2 is provided in the middle of the workbench 1, with a telescopic slot 21 reserved on the top, a hollow cavity formed inside, and a pair of baffles 22 matching the shape of the pick 3 are provided on the top. The two baffles 22 are symmetrically distributed on both sides of the telescopic slot 21, and are used to position the pick 3 to ensure that the pick 3 remains stable during the welding process. The telescopic slot 21 is located at the center of the combined welding support 2, providing a linkage space for the circulating interval conveying mechanism 4 below and the pick 3.

[0031] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 As shown, the cyclic interval conveying mechanism 4 is installed inside the combined welding support 2, including a power mechanism 41, a transmission component and an intermittent conveying component:

[0032] Power mechanism 41: Motor 1 401 is fixedly mounted on the outer wall of the combined welding support 2, and its output shaft passes through the side wall of the combined welding support 2 and is sleeved and fixed with the driving wheel 42. Motor 1 401 drives the driving wheel 42 to rotate, thereby providing power for the cyclic interval conveying mechanism 4.

[0033] Transmission assembly: A pair of rotating rods 43 distributed on the left and right are rotatably arranged on the inner wall of the combined welding support 2, and a synchronous wheel 44 is sleeved and fixed on the rotating rod 43. The synchronous wheel 44 is connected to the driving wheel 42 through a synchronous belt 45, so that the power of the driving wheel 42 is transmitted to the synchronous wheels 44 on both sides, so as to realize the synchronous rotation of the rotating rods 43 on both sides.

[0034] Intermittent conveying assembly: The other end of the first rotating rod 43 is connected to an intermittent conveying unit 46. The intermittent conveying unit 46 includes a pair of second rotating rods 461 arranged centrosymmetrically. The second rotating rods 461 are distributed at the same height as the first rotating rod 43 and are located on the side of the first rotating rod 43 close to the center of the combined welding support 2. The ends of the first rotating rod 43 and the second rotating rods 461 are respectively connected to a first crank 462 and a second crank 463. The rear sides of the other ends of the first crank 462 and the second crank 463 are jointly connected to a U-shaped plate 464. The U-shaped plates 464 on the left and right sides are connected to a toothed plate frame 47 through a connecting rod 465. A number of equally spaced teeth 48 are arranged on the top of the toothed plate frame 47. The teeth 48 are in sliding fit with the outer wall of the pick 3, and the toothed plate frame 47 is in sliding connection with the telescopic groove 21.

[0035] When the first motor 401 drives the driving wheel 42 to rotate, the synchronous wheel 44 and the first rotating rod 43 are driven to rotate through the synchronous belt 45. The first crank 462 on the first rotating rod 43 rotates accordingly, and the toothed plate frame 47 is driven to perform a lifting and rotating cyclic movement in the telescopic groove 21 through the U-shaped plate 464 and the connecting rod 465. When the toothed plate frame 47 rises, the teeth 48 contact the outer wall of the pick 3 and push the pick 3 forward by a certain distance; when the toothed plate frame 47 descends, the teeth 48 disengage from the pick 3, completing one conveying cycle, thereby realizing the synchronous conveying of the picks 3 at equal time intervals and equal distances.

[0036] The induction welding mechanism 5 is installed on the workbench 1, and a high-frequency induction coil 6 is extended and arranged on its front side. The induction welding mechanism 5 energizes the high-frequency induction coil 6 for operation. The high-frequency induction coil 6 includes bent induction coils 61 arranged at its left and right ends. The bent induction coils 61 are located above the pick 3 and fit the shape of the pick 3, and can more accurately perform induction heating on the welding part of the pick 3, improving the welding efficiency and quality. The induction welding mechanism 5 and the high-frequency induction coil 6 are both prior arts and are used for metal welding.

[0037] Please refer to the attached Figure 1 、attached Figure 2 、attached Figure 6 and attached Figure 7 As shown in the figures, a fixed bracket 7 is arranged at the rear side of the combined welding support 2. A solder adding mechanism 8 is installed on the fixed bracket 7, including a power unit, a transmission unit, and a feeding unit:

[0038] Power unit: The second motor 81 is fixedly installed on the fixed bracket 7. After its output shaft passes through the fixed bracket 7, it is eccentrically connected to a grooved wheel 82.

[0039] Transmission unit: An annular sliding groove 83 is reserved on the front side of the grooved wheel 82. An installation bracket 84 is arranged below the grooved wheel 82. A feeding pipe 85 is slidably arranged on the installation bracket 84. A connecting block 86 is arranged at the top of the feeding pipe 85. A linkage rod 87 is arranged on the connecting block 86. The linkage rod 87 is in sliding fit with the annular sliding groove 83.

[0040] Filler unit: The filler pipe 85 is located directly above the pick 3 and is connected to an external solder conveying mechanism for conveying solder to the welding part of the pick 3.

[0041] When the second motor 81 drives the sheave 82 to rotate, the annular chute 83 rotates accordingly, and drives the connecting block 86 and the filler pipe 85 to reciprocate up and down on the mounting bracket 84 through the linkage rod 87. When the pick 3 is conveyed to the welding position, the filler pipe 85 descends to an appropriate height to precisely release solder onto the top of the pick 3, and then rises and resets to wait for the next addition operation. This mechanism realizes the precise quantitative addition of solder through cooperation with the cyclic intermittent conveying mechanism 4.

[0042] In the specific implementation of the present utility model: The pick 3 to be welded is conveyed by the conveying mechanism to the combined welding support 2. After being positioned by the baffle 22, the tooth block 48 of the cyclic intermittent conveying mechanism 4 pushes the pick 3 to move equidistantly along the telescopic groove 21 towards the output mechanism. At the same time, the solder adding mechanism 8 makes a lifting cyclic movement on the fixed support 7 and releases solder onto the top of the pick 3 at an appropriate time. When the pick 3 moves inside the high-frequency induction coil 6, the high-frequency induction coil 6 inductively heats the welding part of the pick 3, and the bending induction coil 61 inductively heats the top of the pick 3. The solder melts at high temperature to realize the welding of the pick 3. After welding is completed, the pick 3 continues to be conveyed by the cyclic intermittent conveying mechanism 4 to the output mechanism to complete the entire welding process.

[0043] It is worth mentioning that the first motor 401, the second motor 81, the induction welding mechanism 5, and the high-frequency induction coil 6 in this new type are all well-known existing devices in the art, and their circuit connection methods and usage control methods are all prior arts.

[0044] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
