Description

Technical Field

[0001] This application relates to the field of welding equipment, and particularly to a feeding device for drill bit welding. Background Art

[0002] To improve the hardness and service life of drill bits, cemented carbide blades are often welded to the ends of drill bits. Compared with drill bits made entirely of cemented carbide, on the one hand, the processing difficulty is reduced, and on the other hand, the production cost of drill bits is reduced.

[0003] When welding a cemented carbide blade to a drill bit, it needs to go through processing at multiple stations, that is, multiple devices need to be correspondingly arranged on the drill bit welding equipment. In the related art, when using a drill bit welding equipment to weld a drill bit and a blade, first, a cutting device is required to open a blade slot for inserting the blade at the end of the drill bit. Then, a copper bar is loaded into the blade slot through a copper bar feeding device, and then a welding powder is loaded into the blade slot through a welding powder feeding device. Then, the blade is loaded into the blade through a blade installation device, and finally, the copper bar, welding powder, drill bit, and blade are heated by a heating device to complete the welding.

[0004] Although the drill bit welding equipment in the related art can weld the blade to the drill bit, the equipment requires a large number of devices, resulting in a large floor area of the equipment, which needs to be improved. Summary of the Invention

[0005] In order to reduce the floor area of the drill bit welding equipment, this application provides a feeding device for drill bit welding.

[0006] A feeding device for drill bit welding provided by this application adopts the following technical solutions:

[0007] A feeding device for drill bit welding includes

[0008] a feeding mechanism, including a feeding seat, a pushing plate slidably arranged on the feeding seat, and a pushing driving source for driving the pushing plate to move;

[0009] a copper bar transmission mechanism for transmitting a copper bar to the feeding seat;

[0010] a cutting mechanism for cutting the copper bar;

[0011] a welding powder transmission mechanism for transmitting welding powder to the feeding seat.

[0012] By adopting the above technical solutions, when welding a drill bit, first, the drill bit is transmitted to the feeding seat. At the same time, the copper bar is transmitted to the feeding seat through the copper bar transmission mechanism and the copper bar is cut by the cutting mechanism. The welding powder is transmitted to the feeding seat through the welding powder transmission mechanism. Then, the pushing driving source drives the pushing plate to move to transmit the copper bar and the welding powder into the blade slot on the drill bit.

[0013] With such a setting, the station for performing the function of feeding the copper strip and the station for performing the function of feeding the welding powder are integrated, so that the feeding of the copper strip and the feeding of the welding powder can be completed at one station, reducing the floor area of the drill bit welding equipment.

[0014] Optionally, it further includes a frame. The feeding seat is slidably arranged on the frame, and the sliding direction of the feeding seat is the same as the sliding direction of the pushing plate. The feeding mechanism further includes a feeding driving source for driving the feeding seat to move.

[0015] By adopting the above technical solution, before loading the copper strip and the welding powder into the blade groove, the feeding driving source is first used to drive the feeding seat to move towards the direction close to the blade groove, so as to minimize the distance between the copper strip and the welding powder and the blade groove, which helps the pushing plate to push the welding powder and the copper strip into the blade groove.

[0016] Optionally, a feeding groove is formed on one side side wall of the feeding seat, a copper strip hole communicating with the feeding groove is formed on the other side side wall of the feeding seat, and the feeding groove communicates with the top wall of the feeding seat.

[0017] By adopting the above technical solution, when transmitting the copper strip, the end of the copper strip is inserted into the copper strip hole so that the end of the copper strip can move into the feeding groove, and then the copper strip is cut off by the cutting mechanism. When transmitting the welding powder, the welding powder is transmitted to the feeding groove through the welding powder transmission mechanism. The groove wall of the feeding groove limits and guides the copper strip cut by the cutting mechanism and the welding powder, which helps the copper strip and the welding powder to enter the blade groove.

[0018] Optionally, it further includes a bracket. The cutting mechanism includes a cutter slidably arranged on the bracket and a cutting driving source for driving the cutter to move. A cutting groove communicating with the feeding groove is formed on the feeding seat, and the cutting groove is used for the end of the cutter to extend into.

[0019] By adopting the above technical solution, when cutting off the copper strip, the copper strip is first inserted into the feeding groove and the cutting groove, and then the cutting driving source is used to drive the cutter to move. The end of the cutter moves into the cutting groove and cuts off the copper strip. With such a setting, it helps the cutter to completely cut off the copper strip.

[0020] Optionally, the cutting mechanism further includes a moving seat, a pressing block slidably arranged on the moving seat along the sliding direction of the cutter, a pressing spring for driving the pressing block to move away from the moving seat. The cutting driving source is used to drive the moving seat to move. The cutter is arranged on the moving seat. The feeding groove is used for the pressing block to extend into, and the pressing block is used to press against the copper strip.

[0021] By adopting the above technical solution, when cutting the copper bar, first drive the moving seat to move towards the feeding seat by the cutting drive source. The pressing block and the cutting tool move together until the pressing block presses against the copper bar. Under the action of the pressing spring, the pressing block keeps pressing the copper bar to limit the displacement of the copper bar. Continue to drive the moving seat to move. The pressing block moves relative to the moving seat, and the cutting tool moves together with the pressing block, that is, the cutting tool moves relative to the pressing block, so as to cut the copper bar.

[0022] With such a setting, on the one hand, the movement of the copper bar during cutting is restricted, improving the section quality of the cut copper bar segments. On the other hand, the pressing block and the cutting tool can be driven to move together by the cutting drive source, and at the same time, the relative movement between the pressing block and the cutting tool can be realized. Compared with the cutting tool and the pressing block being controlled by different drive sources respectively, the number of drive sources is reduced, and the integration degree of the feeding device of the present application is further improved.

[0023] Optionally, the solder powder transmission mechanism includes a hopper arranged on the bracket, a telescopic tube with two ends respectively connected to the lower end of the hopper and the pressing block, and a closing component for opening and closing the opening of the telescopic tube. The closing component includes a closing ring arranged in the telescopic tube, a closing plug slidably arranged in the telescopic tube, an opening rod connected to the side of the closing plug away from the hopper, and a closing spring for driving the closing plug to move towards the opening rod. The closing ring is used for the closing plug to be inserted, the closing spring is used for driving the closing plug to be inserted into the closing ring, the opening rod is used for abutting against the closing plug. When the pressing block presses tightly against the copper bar, the opening rod abuts against the wall of the feeding groove, and the closing plug is separated from the closing ring.

[0024] By adopting the above technical solution, when the cutting drive source drives the moving seat to move, the pressing block and the end of the telescopic tube move together, thereby reducing the distance between the end of the telescopic tube and the feeding seat until the pressing block presses tightly against the copper bar. At this time, the end of the telescopic tube extends into the feeding groove and the opening rod abuts against the wall of the feeding groove, so that the closing plug moves to separate itself from the closing ring, and the solder powder in the hopper enters the feeding groove through the telescopic tube. Continue to drive the moving seat to move by the cutting drive source, and the cutting tool cuts the copper strip.

[0025] After the copper strip is cut and the solder powder is transmitted, the moving seat is reset by the cutting drive source, the pressing block and the telescopic tube are reset, the opening rod is separated from the wall of the feeding groove. Under the action of the closing spring, the closing plug moves towards the opening rod, so that the closing plug moves again to tightly abut against the closing ring, thereby restricting the solder powder from flowing out of the telescopic tube.

[0026] With such a setting, when the cutting drive source compresses the copper strip through the pressing block, the inner cavity of the telescopic tube can be opened, and the welding powder is conveyed into the feeding trough. This further improves the integration of the feeding device of the present application and reduces the floor area of the feeding device of the present application. When the pressing block abuts against the copper strip, the telescopic tube starts to discharge material. When the cutter completes the cutting and the pressing block separates from the copper strip, the telescopic tube stops discharging material to ensure sufficient discharge of the welding powder. And by shortening the distance between the telescopic tube and the wall of the feeding trough, the amount of welding powder conveyed into the feeding trough can be controlled.

[0027] Optionally, the closing assembly further includes a corrugated sleeve sleeved on the closing spring.

[0028] By adopting the above technical solution, by sleeving a corrugated sleeve on the closing spring, direct contact between the welding powder and the closing spring is isolated while minimizing the influence on the expansion and contraction of the closing spring, which helps the closing spring to expand and contract normally.

[0029] Optionally, the pushing plate includes a lower pushing plate, an upper baffle plate slidably disposed on the upper side of the lower pushing plate, and a spacer spring connecting the upper pushing plate and the lower pushing plate. A limiting plate for abutting against the upper baffle plate is disposed in the feeding trough. The pushing drive source is used to drive the lower pushing plate to move. The sliding direction of the upper baffle plate is the same as that of the lower pushing plate. When the spacer spring is in a natural state, the end of the upper baffle plate close to the limiting plate is located on the side close to the limiting plate of the end of the lower baffle plate close to the limiting plate.

[0030] By adopting the above technical solution, since the end of the upper baffle plate close to the limiting plate is located on the side close to the limiting plate of the end of the lower baffle plate close to the limiting plate when the spacer spring is in a natural state, when the pushing drive source drives the lower pushing plate to move, the upper baffle plate and the lower pushing plate move together. The upper baffle plate first enters the feeding trough so that the copper strip and the welding powder are located between the upper baffle plate and the wall of the feeding trough until the upper baffle plate abuts against the limiting plate. Continuing to drive the lower pushing plate to move through the pushing drive source, the lower pushing plate moves relative to the upper pushing plate, thereby pushing the welding powder and the copper strip to move so that the copper strip and the welding powder enter the blade groove. With such a setting, when the lower pushing plate pushes the welding powder and the copper strip to move, the offset of the copper strip and the dispersion of the welding powder are effectively restricted, which helps the copper strip and the welding powder to enter the blade groove.

[0031] Optionally, the copper strip transmission mechanism includes a clamping assembly for clamping the copper strip and a moving member for driving the clamping assembly to move.

[0032] By adopting the above technical solution, when transmitting the copper strip, first clamp the copper strip through the clamping assembly, and then drive the clamping assembly to move through the moving member to make the copper strip move. Through the copper strip transmission mechanism, the full automation of copper strip transmission is realized.

[0033] Optionally, the copper strip transmission mechanism includes a guide plate, and the guide plate is provided with a guide hole for the copper strip to pass through.

[0034] By adopting the above technical solution, when transmitting the copper bar, the end of the copper bar is first passed through the guiding hole on the guiding plate. The guiding hole plays a guiding role for the copper bar, and it can avoid the deviation of the copper bar during transmission as much as possible.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. The copper bar is transmitted to the loading seat through the copper bar transmission mechanism and the cutting mechanism, and the welding powder is transmitted to the loading seat through the welding powder transmission mechanism. Then, the welding powder and the copper bar are transmitted to the blade groove through the loading mechanism. With such a setting, the functions of loading the copper bar and loading the welding powder are integrated, reducing the floor area of the drill welding equipment;

[0037] 2. When cutting the copper bar, the moving seat is driven to move by the cutting driving source, so that the pressing block and the cutting knife move together first. After the pressing block presses against the copper bar, the cutting knife moves relative to the pressing block and cuts the copper bar. Compared with controlling the movement of the pressing block and the cutting knife respectively by different driving sources, with such a setting, the number of driving sources is reduced, and the integration degree of the loading device of the present application is further improved;

[0038] 3. When the cutting driving source drives the moving seat to move, the end of the pressing block and the telescopic tube move together with the pressing block to reduce the distance between the end of the telescopic tube and the wall of the loading groove. When the pressing block presses against the copper bar, under the action of the opening rod, the closing plug is separated from the closing ring, and the welding powder enters the loading groove, further improving the integration degree of the loading device of the present application and reducing the floor area of the loading device of the present application; Description of the Drawings

The limiting plate 65 is fixed on the groove wall of the loading groove 611 and is used for abutting against the limiting plate 65. The spacer spring 633 expands and contracts along the sliding direction of the lower pushing plate 631, and both ends of the spacer spring 633 are respectively fixed on the upper baffle plate 632 and the lower pushing plate 631. When the spacer spring 633 is in a natural state, the end of the upper baffle plate 632 close to the limiting plate 65 is located on the side close to the limiting plate 65 of the end of the lower baffle plate close to the limiting plate 65.

[0054] Referring to Figure 2 , when the lower pushing plate 631 is driven by the pushing driving source 64 to move towards the direction close to the limiting plate 65, under the action of the spacer spring 633, the upper baffle plate 632 and the lower pushing plate 631 move until the upper baffle plate 632 abuts against the limiting plate 65. At this time, when the lower pushing plate 631 continues to move, the lower pushing plate 631 moves relative to the upper pushing plate.

[0055] Reference Figure 3 As shown in Figure 3 , the cutting mechanism 4 includes a cutting drive source 41, a moving seat 42, a pressing block 43, a cutting knife 44, and two pressing springs 45.

The moving seat 42 is slidably arranged on the bracket 2 in the vertical direction. The cutting knife 44 is fixed on the moving seat 42 to move together with the moving seat 42. A cutting groove 613 penetrating the feeding seat 61 in the vertical direction is formed on the top wall of the feeding seat 61.

The feeding groove 611 is used for the pressing block 43 to extend into, and the pressing block 43 is used to press against the copper strip. Two connecting rods 46 are arranged on the pressing block 43. One end of the connecting rod 46 is fixedly connected to the pressing block 43. A limiting block 47 with a diameter larger than that of the connecting rod 46 is fixed at one end of the connecting rod 46. The connecting rod 46 penetrates and is slidably arranged on the moving seat 42 in the vertical direction. When the limiting block 47 abuts against the moving seat 42, the lower end surface of the pressing block 43 is flush with the lower end surface of the cutting knife 44. The two pressing springs 45 are respectively sleeved on different connecting rods 46. The pressing springs 45 expand and contract in the vertical direction, and the two ends of the pressing springs 45 respectively abut against the moving seat 42 and the adjacent pressing block 43 to apply a force to the pressing block 43 in the direction away from the moving seat 42.

[0058] Reference Figure 1 、 Figure 3 As shown in Figure 1 and Figure 3 , when cutting the copper strip, first, the end of the copper strip is transported into the feeding groove 611 of the feeding seat 61 through the copper strip transmission mechanism 3, and then the cutting drive source 41 drives the moving seat 42 to move downward. Under the action of the pressing spring 45, the limiting block 47, and the connecting rod 46, the pressing block 43 moves downward with the moving seat 42. At this time, the cutting knife 44 and the pressing block 43 move downward together until the pressing block 43 presses against the copper strip. Continuing to drive the moving seat 42 to move downward through the cutting drive source 41, the cutting knife 44 moves downward with the moving seat 42, and the end of the cutting knife 44 extends into the cutting groove 613, thereby cutting off the copper strip.

[0059] Reference Figure 3 、 Figure 4, the solder powder transfer mechanism 5 includes a hopper 51 disposed on the bracket 2, a telescopic tube 52 located below the hopper 51, and a closing assembly 53 for opening and closing the opening of the telescopic tube 52. The hopper 51 is used to load solder powder, and the opening of the hopper 51 faces downward. The two ends are respectively fixed on the hopper 51 and the pressing block 43. The telescopic tube 52 is a corrugated tube. The telescopic tube 52 extends in the vertical direction, and the telescopic tube 52 penetrates through the pressing block 43 and the moving seat 42 in the vertical direction. The moving seat 42 is fixedly connected to the telescopic tube 52.

[0060] Refer to Figure 4 , the closing assembly 53 includes a closing ring 531 disposed in the telescopic tube 52, a closing plug 532 slidably disposed in the telescopic tube 52, a mounting bracket 533 connected to the inner wall of the telescopic tube 52, three closing springs 534 disposed between the mounting bracket 533 and the closing plug 532, and three bellows sleeves 535 respectively sleeved on different closing springs 534. The closing ring 531 is fixed to the lower end of the inner wall of the telescopic tube 52, and the closing ring 531 is used for the closing plug 532 to be inserted.

[0061] Refer to Figure 4 , the mounting bracket 533 is fixed at the connection between the telescopic tube 52 and the moving seat 42 so that the mounting bracket 533 is fixed relative to the moving seat 42. The closing spring 534 expands and contracts in the vertical direction, and the two ends of the closing spring 534 abut against the mounting bracket 533 and the closing plug 532 to apply a downward force to the closing plug 532. The two ends of the bellows sleeve 535 are respectively fixedly connected to the mounting bracket 533 and the closing plug 532 to minimize the influence of solder powder on the expansion and contraction of the closing spring 534. Two guide rods 536 extending in the vertical direction are fixed on the closing plug 532. The guide rods 536 penetrate through and are slidably disposed on the mounting bracket 533 in the vertical direction to guide the sliding of the closing plug 532.

[0062] Refer to Figure 4 , the closing assembly 53 further includes a plurality of opening rods 537 fixed to the lower side of the closing plug 532. The length of the opening rod 537 is greater than the diameter of the copper bar. The opening rod 537 is used to abut against the closing plug 532. When the pressing block 43 abuts against the copper bar, the opening rod 537 abuts against the groove wall of the feeding trough 611, and the closing plug 532 is separated from the closing ring 531.

[0063] Refer to Figure 3 , Figure 4, when transporting the welding powder, the cutting drive source 41 drives the moving seat 42 and the pressing block 43 to move downward, and the lower end of the telescopic pipe 52 moves downward. Under the action of the closing spring 534, the closing plug 532 remains tightly pressed against the closing ring 531 until the opening rod 537 presses against the wall of the feeding trough 611. Continuing to drive the moving seat 42 and the pressing block 43 downward, the pressing block 43, the lower end of the telescopic pipe 52, and the closing ring 531 continue to move downward, so that the closing plug 532 is separated from the closing ring 531, the inner cavity of the telescopic pipe 52 is opened, and the welding powder in the telescopic pipe 52 leaks downward into the feeding trough 611. After the welding powder is transported, the cutting drive source 41 drives the moving seat 42 and the pressing block 43 to move upward and reset. Under the action of the closing spring 534, the closing plug 532 moves back to tightly press against the closing ring 531 by itself.

[0064] The implementation principle of the feeding device for drill bit welding in the embodiment of the present application is as follows: when welding a drill bit, first, the end of the copper bar is transported into the feeding trough 611. Secondly, the cutting drive source 41 drives the moving seat 42 to move downward until the pressing block 43 tightly presses against the copper bar and the closing plug 532 moves to separate from the closing ring 531 by itself. At this time, the welding powder enters the feeding trough 611 from the telescopic pipe 52. Then, continue to drive the moving seat 42 to move downward through the cutting drive source 41, and the cutting tool 44 moves relative to the pressing block 43 to cut off the copper bar. Then, the cutting drive source 41 resets the moving seat 42 upward, the closing plug 532 tightly presses against the closing ring 531 again, and the telescopic pipe 52 and the pressing block 43 move upward and reset. Then, the feeding drive source 62 drives the feeding seat 61 to move to reduce the distance between the feeding seat 61 and the drill bit. Finally, the pushing drive source 64 drives the lower pushing plate 631 to move, and the lower pushing plate 631 drives the upper baffle plate 632 to move through the spacer spring 633 until the upper baffle plate 632 tightly presses against the limiting plate 65. At this time, the copper bar and the welding powder are located between the upper baffle plate 632 and the wall of the feeding trough 611. Continuing to drive the lower pushing plate 631 to move, the lower pushing plate 631 moves relative to the upper baffle plate 632 to push the welding powder and the copper bar into the blade groove.

[0065] With such a setting, the feeding device of the present application integrates the feeding of the copper bar and the feeding of the welding powder, effectively reducing the floor area of the drill bit welding equipment.

[0066] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
