Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to a material collection and conveying mechanism for a welding rod traction shearing machine. Background Technology

[0002] Welding electrodes are metal strips that melt and fill the joint of welded workpieces during gas welding or electric welding. They are an indispensable consumable in the welding process.

[0003] The production of welding electrodes mainly involves the preparation of the core and the coating, the pressing of the coating onto the core, drying, and packaging. The core is primarily made by cutting the drawn steel wire to a fixed length using a shearing machine. Modern shearing machines mainly consist of a traction mechanism and a shearing mechanism. The traction mechanism pulls the metal strip to the shearing mechanism and cuts it to a certain length. To ensure stable shearing, existing shearing mechanisms have a shearing table below the cutter. The traction mechanism pulls the metal strip to the shearing table for cutting. However, after shearing, the cut metal strip lingers briefly on the shearing table, resulting in poor unloading and affecting production efficiency.

[0004] Secondly, currently, when receiving materials, the material frame is usually placed directly on the discharge end of the shearing machine, and the sheared welding rods fall directly into the material frame. Therefore, it is inconvenient to inspect the surface of the welding rods after they have been sheared.

[0005] In summary, improvements are needed to the existing traction shearing machine. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welding rod traction shearing machine, which aims to solve the problems mentioned in the background technology.

[0007] The technical solution of this utility model is implemented as follows: a welding electrode traction shearing machine, comprising:

[0008] The frame is equipped with a traction device and a shearing device; the shearing device has a cutter and a shearing table; the traction device is used to pull the welding rod to move onto the shearing table; it also includes an unloading device, which has a movable pusher block that can push the sheared welding rod away from the shearing table when the pusher block moves.

[0009] Preferably, the unloading device includes a bracket mounted on the frame;

[0010] The pusher block is mounted on a rotatable support.

[0011] The pusher block has a pusher section, and the pusher block can be rotated by a first motor.

[0012] Preferably, there are at least two pusher blocks.

[0013] By adopting the above technical solution:

[0014] In order to enable the sheared welding rod to be used on the shearing table more quickly, this utility model provides an unloading device on the support. The unloading device rotates the pusher block under the control of the motor, and pushes the welding rod away from the shearing table through the pusher part on the pusher block, thereby improving the unloading efficiency.

[0015] Preferably, it further includes a material collection device mounted on the frame and located at the bottom of the shearing device, and a conveying device located below the material collection device;

[0016] The material collection device can store the sheared welding rods and control the welding rods to fall onto the conveying device one by one.

[0017] Preferably, the collecting device includes:

[0018] The material collection frame is installed on the frame and has a material collection cavity;

[0019] The material discharge channel is formed inside the material collection frame and is connected to the material collection cavity;

[0020] The material collection frame is rotatably connected to the material discharge rollers located on both sides of the material discharge channel, and the material discharge channel is open to form a discharge port.

[0021] Preferably, the conveying device includes: a conveying support;

[0022] The conveyor roller is rotatably connected to the conveyor support;

[0023] The conveyor belt is connected between the conveyor rollers.

[0024] The conveying roller can be controlled to rotate by a second motor.

[0025] Preferably, the bottom of the collecting chamber is inclined from the side wall towards the material channel.

[0026] Preferably, the material collection frame is rotatably connected to gears that are coaxially connected to each feeding roller, and the gears mesh with each other.

[0027] Preferably, a feeding plate is installed on the conveying support.

[0028] Preferably, the conveying support can be provided with a material frame, and the conveying support is provided with a limiting groove, the width of the limiting groove gradually increasing from the groove opening to the groove bottom;

[0029] The material frame has a limiting block, and the width of the limiting block gradually increases outward from the connection point with the material frame;

[0030] The maximum width of the limiting block is greater than the minimum width of the limiting groove.

[0031] By adopting the above technical solution:

[0032] 1. This utility model is equipped with a material collection device and a conveying device on the frame. The sheared welding rods can be temporarily stored in the material collection device, and then the material discharge rollers of the material collection device drop them one by one onto the conveyor belt. The welding rods on the conveyor belt can be screened by workers, and welding rods that are obviously unqualified (such as those with serious damage to the outer wall) can be removed.

[0033] 2. One end of the feeding roller of this utility model is coaxially connected to a gear, and the gears on each feeding roller mesh with each other. Therefore, only one motor is needed to drive the two feeding rollers to rotate relative to each other.

[0034] 3. To assist in material feeding, this utility model includes an inclined feeding plate on the conveying support. To prevent the material frame from moving during material receiving, limiting blocks and limiting grooves are provided on the material frame and the conveying support. During material receiving, the material frame can be restricted to the conveying support. Since the conveying device can deliver welding rods when the empty material frame is receiving material, the welding rods may fall into the material frame and impact it, which can easily cause the material frame to deviate. This utility model restricts the material frame to the conveying support to prevent the material frame from deviating.

[0035] Unless otherwise specified, the welding rod in this utility model refers to the welding rod substrate formed after cutting a metal strip, and the welding rod substrate is the substrate before the flux coating process. Attached Figure Description

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Example 1:

[0049] like Figures 1-4 As shown, this utility model discloses a welding electrode traction shearing machine, comprising:

[0050] The frame 10 is equipped with a traction device and a shearing device; the shearing device has a cutter and a shearing table; the traction device is used to pull the welding rod to move onto the shearing table.

[0051] In this embodiment, the traction device includes a housing 20 fixedly mounted on the frame 10, a traction bracket 21 fixed on the frame on one side of the housing 20, and a traction roller 22 rotatably connected to the traction bracket. Each traction roller 22 is coaxially connected to a traction gear 23. In this embodiment, the upper traction gear 23 and the lower traction gear 23 mesh with each other, and a traction motor 24 is installed inside the housing 20. The principle of the traction device in this embodiment is that the traction motor controls the rotation of the traction gear and the rotation of the lower traction roller. The lower traction gear controls the rotation of the upper traction gear and synchronously drives the upper traction roller to rotate. When the upper and lower traction rollers rotate synchronously, they drive the metal strip to move towards the shearing device.

[0052] In this embodiment, the shearing device includes a shearing bracket 30 fixed on the frame 10, a hydraulic cylinder 31 mounted on the shearing bracket 30, and a first shearing table 32 and a second shearing table 33 arranged longitudinally at intervals (the first shearing table 32 and the second shearing table constitute the shearing table in this embodiment). A cutter 34 is mounted on the piston shaft (that is, the output end of the hydraulic cylinder) of the hydraulic cylinder 31. During shearing, the metal strip is controlled by the traction device to move between the first shearing table and the second shearing table. Then, the hydraulic cylinder 31 controls the cutter to reciprocate up and down and cut the metal strip below the cutter, thereby forming a welding rod substrate.

[0053] It also includes an unloading device, which has a movable pusher block 40 that can push the sheared welding rod away from the shearing table when the pusher block 40 is movable.

[0054] In this embodiment: the unloading device includes: a bracket 41, which is mounted on the frame 10;

[0055] The pusher block 40 is rotatably supported on the bracket 41 via the drive shaft 40a;

[0056] The pusher block 40 has a pusher part 40b, and the pusher block 40 can be rotated by the first motor 43.

[0057] In this embodiment: there are two pusher blocks 40, and the pusher blocks 40 are coaxially arranged, that is, the two pusher blocks 40 are axially spaced on the transmission shaft 40a.

[0058] In this embodiment, the frame 10 is provided with a discharge port 50, and a limiting frame 51 located at the discharge port 50 is provided on the frame 10. The limiting frame 51 in this embodiment is L-shaped.

[0059] The unloading principle of this embodiment is as follows: after the metal strip is cut on the cutting table, the first motor drives the pusher block to rotate, and the pusher pushes the cut welding rod away from the support and falls into the discharge port.

[0060] The limiting frame set in this embodiment can prevent the welding rod from falling into the area outside the discharge port when the pusher block unloads the material.

[0061] Example 2 differs from Example 1 in that:

[0062] like Figures 5-10 As shown, in this embodiment, a material collection device 6 located at the bottom of the shearing device and a conveying device located below the material collection device are installed on the frame 10.

[0063] The material collection device 6 can store the sheared welding rods and control the welding rods to fall onto the conveying device one by one.

[0064] In this embodiment: the collecting device includes:

[0065] The material collection frame 60 is installed on the frame 10 and has a material collection cavity 61;

[0066] The material discharge channel 62 is formed inside the material collection frame 60 and is connected to the material collection cavity 61;

[0067] The material collection frame 60 is rotatably connected to the material discharge channel 62 on both sides. The material discharge channel 62 is open and forms a discharge port. The material discharge rollers 63 can be driven by a third motor 63a.

[0068] In this embodiment, the frame 10 is provided with an installation port 64 for placing the collection frame 60. The inner wall of the installation port 64 is provided with a support plate 65, and the collection frame 60 is provided with a limiting plate 66. When the collection frame 60 is placed in the installation port 64, the limiting plate 66 is supported by the support plate 65.

[0069] In this embodiment: the conveying device includes: a conveying support 70;

[0070] The conveyor roller 71 is rotatably connected to the conveyor support 70 via a rotating shaft;

[0071] The conveyor belt 72 is driven between the conveyor rollers 71;

[0072] The conveying roller 71 can be controlled to rotate by the second motor 73.

[0073] In this embodiment, the bottom of the collecting chamber 61 is inclined from the side wall towards the material channel 62.

[0074] In this embodiment: the material collection frame 60 is rotatably connected to a gear 80 coaxially connected to each feeding roller 63, and each gear 80 meshes with each other. The gear 80 can be coaxially connected to the feeding roller 63 through a shaft.

[0075] In this embodiment: a feeding plate 70a is installed on the conveying bracket 70. The feeding plate is inclined downward to guide the welding rod into the material frame.

[0076] In this embodiment: the conveying bracket 70 can be limited to a material frame 9. In this embodiment, the material frame 9 is preferably a material cart, so that the bottom is equipped with wheels for easy movement.

[0077] In this embodiment, the conveying bracket 70 is provided with a limiting groove 92, the width of the limiting groove 92 gradually increases from the groove opening to the groove bottom, and the limiting groove 92 is a dovetail groove;

[0078] The material frame 9 has a limiting block 93, which can be welded to the side wall of the material frame 9. The width of the limiting block 93 gradually increases outward from the connection with the material frame 9. The limiting block 93 is a dovetail block.

[0079] Among them, the maximum width h1 of the limiting block 93 is greater than the minimum groove width h2 of the limiting groove 92.

[0080] In this embodiment, the limiting plate 66 of the material collection frame 60 is provided with a first handle 94 and a second handle 95.

[0081] In this embodiment, the limiting frame includes a first plate 96 on the mounting frame 10 and a second plate 97 mounted on the limiting plate 66.

[0082] refer to Figures 5-10 The principle of this embodiment is:

[0083] The cut welding rod substrate falls into the collection frame for storage, and then when the third motor controls the relative rotation of the feeding rollers (such as...), Figure 9 As shown, the left feeding roller rotates clockwise and the right feeding roller rotates counterclockwise, driving the welding rods in the collection chamber to be discharged one by one from the discharge port and fall onto the conveyor belt. The conveyor belt controls the welding rods to move towards the material frame and discharges the welding rods into the material frame through the feeding plate.

[0084] As the welding rods move on the conveyor belt, workers can screen them and remove those that are obviously defective (such as those with cracks or severe outer wall defects).

[0085] It should be noted that: In this embodiment, limiting grooves and limiting blocks are set on the conveying bracket and the material frame. When the material frame is moved, the limiting block can be inserted into the limiting groove. This way, when the welding rod falls into the material frame, the material frame will not move significantly, thus ensuring that the welding rod enters the frame. In this embodiment, the dimensions of the limiting groove and the limiting frame do not need to be matched. Furthermore, in order to move the material frame efficiently, the size of the limiting groove should be as large as possible than the limiting block. It is only necessary to ensure that the maximum width of the limiting block is greater than the minimum groove width of the limiting groove.

[0086] Secondly, the material collection device in this embodiment can also be removed from the frame. One way to remove the material collection device is to lift one end of the material collection device with the first handle or the second handle and slowly move it until the frame of the material collection frame leaves the installation port. Then, lift the material collection device through the bottom of the material collection frame and take it out. The first handle and the second handle can be used by multiple people to lift the material collection device at the same time.

[0087] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
