[0071] The embodiments of the present application will be described in detail below.

[0072] Embodiment 1

[0073] Referring to Figures 1-18 , the present embodiment provides a sintering furnace 8 automatic transfer device, including frame 1, transfer mechanism 2, cooling mechanism, tray conveying tool 4 and mold transfer tool 5.

[0074] The frame 1 is in the shape of a straight line as a whole, and the transfer station 11 and the cooling station 12 are distributed along the length direction of the frame 1, the opposite sides of the transfer station 11 are respectively provided with the feeding station 13 and the lifting platform 81 capable of entering and leaving the sintering furnace 8.

[0075] The transfer mechanism 2 is arranged in the transfer station 11, which is used for transferring the tray 6 located in the feeding station 13 to the transfer station 11 and positioning the tray 6, or for transferring the tray 6 located in the transfer station 11 to the feeding station 13.

[0076] The cooling mechanism is arranged in the cooling station 12, which is used for cooling the mold 7 after the furnace.

[0077] The tray conveying tool 4 is used for moving the tray 6 with the mold 7 to the feeding station 13, or for moving away the tray 6 and the mold 7 located in the feeding station 13.

[0078] The mold transfer tool 5 is used for transferring the mold 7 between the lifting platform 81 and the transfer station 11, and transferring the mold 7 between the cooling station 12 and the transfer station 11.

[0079] In use, first, the tray 6 is placed on the tray conveying tool 4, the mold 7 filled with alloy powder used for producing a drill bit is placed on the tray 6, the tray 6 with the mold 7 placed thereon is moved to the feeding station 13 by means of the tray conveying tool 4, the tray 6 located at the feeding station 13 is moved to the transfer station 11 and positioned by the transfer mechanism 2, the tray conveying tool 4 is removed, the mold 7 on the tray 6 is transferred to the lifting platform 81 by means of the mold transfer tool 5, the lifting platform 81 lifts the mold 7 into the sintering furnace 8 to heat to melt the alloy powder, then, the mold 7 is lowered with the lifting platform 81, the mold 7 on the lifting platform 81 is first transferred to the transfer station 11 and then to the cooling station 12 for cooling by the mold transfer tool 5, and after cooling, the mold 7 is transferred to the transfer station 11 again, the tray 6 and the mold 7 are transferred to the workshop by the tray conveying tool 4, the drill bit in the mold 7 is taken out in the workshop, and thus the sintering processing of the drill bit body is completed. Subsequent processing such as threading and welding of alloy particles into the drill bit body is performed to make the drill bit product for oil drilling.

[0080] It can be seen that the embodiment does not need manual handling of the tray 6 and the mold 7 between stations, thereby reducing the labor intensity of workers and reducing the risk of workers being scalded by the high-temperature mold 7.

[0081] The cooling mechanism includes a cooling support 31, a water storage tank (not shown in the figure), a cooling nozzle (not shown in the figure), and a cooling cover 32.

[0082] The middle part of the cooling support 31 is hollow. The mold 7 after being taken out of the furnace is placed in the middle part of the cooling support 31.

[0083] The cooling nozzle is arranged below the cooling support 31 and is used to spray cooling water upward to contact the bottom of the mold 7.

[0084] The water storage tank is connected with the cooling nozzle and is arranged below the cooling nozzle.

[0085] The cooling cover 32 is hung above the cooling support 31 and is connected with a winding assembly 33, the winding assembly 33 moves the cooling cover 32 up and down through pulleys, connecting ropes, and other components, and the cooling cover 32 is used to cover the mold 7 on the cooling support 31 and prevent the cooling water from splashing outward.

[0086] The working principle of the cooling mechanism is that after the mold 7 taken out of the furnace is placed in the middle part of the cooling support 31, the cooling water sprayed by the cooling nozzle contacts the bottom of the mold 7 through the cooling support 31 and carries away the heat of the mold 7, thereby achieving the cooling of the mold 7. Before the cooling nozzle is opened, the cooling cover 32 can be lowered to cover the mold 7 to prevent the cooling water from splashing outward.

[0087] The opposite two sides of the tray 6 are provided with rollers 61, and the bottom edge is provided with a traction hole 62 which is a strip-shaped hole; the tray 6 is further provided with a hook 63 and a plug cylinder 64.

[0088] The transfer mechanism 2 comprises a guide frame 21, a guide roller 22, a chain wheel 23, a chain 24, a traction hook 25 and a transfer limiting assembly.

[0089] The rollers 61 are used for rolling contact with the guide frame 21 to guide the movement of the tray 6 through the guide frame 21.

[0090] A plurality of guide rollers 22 are rotationally arranged on the guide frame 21.

[0091] The chain wheel 23 is arranged on the guide frame 21 and located obliquely below the guide roller 22. The chain wheel 23 is driven by electricity.

[0092] The chain 24 is engaged with the chain wheel 23, and the two are used in cooperation.

[0093] The traction hook 25 is arranged on the chain 24, and the traction hook 25 is used for being inserted into the traction hole 62 to pull the tray 6. The traction hook 25 is in the shape of an inverted T, and the horizontal part thereof is used for connecting with the side surface of the chain 24, and the vertical part thereof is used for being inserted into the traction hole 62.

[0094] The transfer limiting assembly is used for limiting the movement of the tray 6 on the guide roller 22. The transfer limiting assembly comprises a latch 26 which is slidingly connected with the frame 1 and cooperates with the plug cylinder 64 on the tray 6 to position the tray 6.

[0095] The working principle of the transfer mechanism 2 is that, in the process of being driven by the chain wheel 23, the traction hook 25 moves with the chain 24 and is inserted into the traction hole 62 to pull the tray 6, so as to realize the transfer of the tray 6 between the transfer station 11 and the feeding station 13. When it is needed to limit the movement of the tray 6 on the transfer station 11 to position the tray 6, the latch 26 is inserted into the plug cylinder 64.

[0096] The tray conveying tool 4 comprises a tray conveying chassis 41, a lifting platform 42, a lifting frame 43, a roller 44 and a tray 6 conveying limiting assembly.

[0097] The tray conveying chassis 41 has a walking function. The tray conveying chassis 41 can be a trolley or an AGV trolley. The lower part of the tray conveying chassis 41 is provided with a positioning pin gear 411, and the transfer station 11 is provided with a positioning hole which is used in cooperation with the positioning pin gear 411.

[0098] The lifting platform 42 is arranged above the tray conveying chassis 41.

[0099] The lifting frame 43 is arranged on the tray conveying chassis 41 and is used for adjusting the vertical distance between the lifting platform 42 and the tray conveying chassis 41.

[0100] A plurality of rollers 44 are rotatably arranged on the lifting platform 42, and the rollers 44 and the guide rollers 22 are capable of rotating in the same direction.

[0101] The tray 6 conveying limiting assembly is used to limit the movement of the tray 6 on the rollers 44, so as to prevent the tray 6 from falling off the lifting platform 42 during the movement of the tray conveying tool 4. The tray 6 conveying limiting assembly comprises side plates 45, a baffle 46 and a pull hook 47.

[0102] The side plates 45 are arranged on the lifting platform 42, and two side plates 45 are arranged at the two ends of the rollers 44 respectively. The rollers 61 are capable of rolling contact with the side plates 45, so as to guide the movement of the tray 6 through the side plates 45.

[0103] The baffle 46 is arranged on the lifting platform 42 and located between the two side plates 45. The baffle 46 and the side plates 45 form a three-sided enclosing structure, and one side of the three-sided enclosing structure is open, and the tray 6 can enter and exit the three-sided enclosing structure through the opening.

[0104] The pull hook 47 is arranged on the lifting platform 42 and used to cooperate with the hook 63 to limit the movement of the tray 6 away from the baffle 46.

[0105] When the tray conveying tool 4 is used to transfer the tray 6 from the feeding station 13 to the transfer station 11, the tray 6 is placed on the rollers 44, the rollers 61 of the tray 6 are in rolling contact with the side plates 45, the pull hook 47 is sleeved on the hook 63 of the tray 6, and the movement of the tray 6 away from the baffle 46 is limited, so as to facilitate the transfer of the tray 6 and the mold 7 loaded with the alloy powder on the tray 6 to the feeding station 13 through the tray conveying tool 4. The positioning insert teeth 411 are pushed into the positioning insert holes, so as to play a positioning role on the tray conveying tool 4. Then, the pull hook 47 and the hook 63 are separated, the traction hook 25 of the transfer mechanism 2 is inserted into the traction hole 62 of the tray 6, the tray 6 is pulled to the guide roller 22 of the transfer mechanism 2, and then the latch 26 is inserted into the insertion cylinder 64 of the tray 6, so as to position the tray 6, thereby facilitating the transfer of the mold 7 on the tray 6. When the tray conveying tool 4 is used to transfer the tray 6 from the transfer station 11 to the feeding station 13, the above process is reversed.

[0106] The mold 7 is in a whole cylindrical shape, and the diameter of the middle part of the mold 7 is greater than the diameter of the two ends of the mold 7.

[0107] The mold transfer tool 5 comprises a mold transfer base plate 51, a transfer support 52, a sliding table 53, a pushing piece 54, an anti-tilting piece 55 and a pull-back piece 56.

[0108] The mold transfer base plate 51 is capable of walking between the cooling station 12 and the transfer station 11. The tray conveying base plate 41 can be a handcart or an AGV trolley.

[0109] The transfer support 52 is arranged on the mold transfer chassis 51. The transfer support 52 has or does not have a lifting function.

[0110] The sliding table 53 is slidingly connected to the top of the transfer support 52. The sliding table 53 is connected to the transfer support 52 through a first driving source. The first driving source is used to make the sliding table 53 reciprocate linearly along a pushing direction. The pushing direction refers to the direction of the shortest line between the lifting platform 81 and the transfer station 11.

[0111] The pushing member 54 is connected to one end of the sliding table 53. The pushing member 54 is used to push the mold 7 from the transfer station 11 to the lifting platform 81. One side of the pushing member 54 is arc-shaped and can contact the lower part of the mold 7.

[0112] The anti-tilting member 55 is located above the pushing member 54 and is used to support one side or multiple sides of the middle part of the mold 7. The anti-tilting member 55 is slidingly connected to the sliding table 53. The sliding table 53 is provided with a second driving source. The second driving source is used to make the anti-tilting member 55 reciprocate linearly along the pushing direction and relative to the sliding table 53, so as to make the anti-tilting member 55 close to or away from the mold 7.

[0113] The pull-back member 56 is rotationally connected to the first side rail 57. The first side rail 57 moves with the anti-tilting member 55. One end of the pull-back member 56 is drivingly connected to a third driving source, and the other end is a free end. The third driving source is installed on the first side rail 57 and is used to rotate the pull-back member 56 along the vertical plane, so that the pull-back member 56 can be in a vertical state or a horizontal state.

[0114] The working principle of the mold transfer tool 5 is that, when the mold 7 is in the transfer station 11, the anti-tilting piece 55 is first moved to the vicinity of the mold 7 by the mold transfer chassis 51, the pull-back piece 56 is rotated to the vertical state by the third driving source, the anti-tilting piece 55 is moved in the pushing direction to approach the side surface of the mold 7 by the second driving source, so as to prevent the mold 7 from tilting in a certain direction in the subsequent process of being “pushed” and “swept”; the pull-back piece 56 is rotated to the horizontal state, and the slide table 53, the pushing piece 54, the anti-tilting piece 55 and the pull-back piece 56 are moved together by the first driving source, so that the mold 7 is pushed from the transfer station 11 to the lifting platform 81 by the pushing piece 54, the lifting platform 81 is raised to send the mold 7 into the sintering furnace 8 for heating, after the heating is completed, the lifting platform 81 drives the mold 7 to descend, so that the mold 7 returns to the position between the pull-back piece 56 and the anti-tilting piece 55, and then the slide table 53, the pushing piece 54, the anti-tilting piece 55 and the pull-back piece 56 are reversely moved together by the first driving source, so that the mold 7 is moved from the lifting platform 81 to the transfer station 11 by the pull-back piece 56; subsequently, the mold transfer chassis 51 is moved, the mold 7 on the transfer station 11 is “swept” to the cooling station 12 by the first side rail 57 for cooling, after the cooling is completed, the mold 7 returns to the tray 6 in the transfer station 11, and subsequently the tray 6 and the mold 7 are transferred to the workshop together by the tray conveying tool 4, the drill bit in the mold 7 is taken out in the workshop, and the sintering process of the drill bit body is completed; subsequently, the drill bit body is processed by threading, welding and embedding alloy particles, and the drill bit product for oil drilling is manufactured.

[0115] In the embodiment, the anti-tilting piece 55 has a gap 551 facing the pull-back piece 56, the mold 7 can enter and exit the gap 551, and the two side walls opposite to each other in the gap 551 can support the two opposite side surfaces of the middle part of the mold 7, so that the anti-tilting effect is good.

[0116] Further, the width of the gap 551 gradually decreases in the direction away from the pull-back piece 56, so that the mold 7 of different sizes can be matched (or be used for contacting different diameter parts of the same mold 7), and the mold 7 can be located on the symmetry line of the gap 551 when the mold 7 is pushed, so that the mold 7 can be accurately pushed to the specified area of the lifting platform 81.

[0117] It should be noted that, in the above scheme, the anti-tilting piece 55 is located above the pushing piece 54; in other embodiments, the anti-tilting piece 55 can also be located below the pushing piece 54. In the above scheme, the anti-tilting piece 55 is formed by two components arranged symmetrically and connected to each other in the shape of a straight-angle trapezoid; in other embodiments, the anti-tilting piece 55 can also be integrally formed.

[0118] Furthermore, the anti-tilt component 55 is also connected to a second side rail 58, which is parallel to the first side rail 57 and moves with the anti-tilt component 55. One end of the second side rail 58 is provided with a supporting component 581, which is used to support the free end of the pull-back component 56 when the pull-back component 56 is in a horizontal state. With the arrangement of the first side rail 57, the second side rail 58 and the supporting component 581, on the one hand, it is beneficial to maintain the horizontal state of the pull-back component 56 during the process of "pulling" the mold 7 from the lifting platform 81 to the transfer platform. On the other hand, during the process of moving the mold 7 from the cooling station 12 to the transfer station 11, the mold 7 in the cooling station 12 can be "sweeped" onto the tray 6 of the transfer station 11 by means of the second side rail 58.

[0119] The slide table 53 is slidably connected to the top of the transfer bracket 52 in the following manner: the bottom of the slide table 53 is connected to the ball bearing 532 via the support leg 531, and the top of the transfer bracket 52 is provided with a guide rail, along which the ball bearing 532 rolls.

[0120] The anti-tilt component 55 and the slide table 53 are slidably connected in the following manner: pulleys 533 are provided on both sides of the slide table 53, and the cross-section of the first side rail 57 and the second side rail 58 is C-shaped. The first side rail 57 and the second side rail 58 are respectively connected to the corresponding pulleys 533. In this way, when the anti-tilt component 55 is moved along the pushing direction to approach the side of the mold 7 by the second driving source, the anti-tilt component 55, the pull-back component 56, the first side rail 57 and the second side rail 58 move relative to the slide table 53 as a whole and can be well supported and guided.

[0121] The first drive source includes a multi-stage electric cylinder 534. The mounting end of the multi-stage electric cylinder 534 is connected to the transfer bracket 52, and the movable end of the multi-stage electric cylinder 534 is connected to the bottom of the slide table 53, so as to realize the overall movement of the slide table 53, the pusher 54, the anti-tilt member 55 and the pull-back member 56 through the first drive source.

[0122] The second drive source includes a lead screw 552 and a slider 553. The two ends of the lead screw 552 are mounted on the upper side of the slide table 53 via bearings.
