Description

Technical Field

[0001] The present invention relates to the field of drill bit sintering, and more particularly to a drill bit sintering device with good flattening effect. Background Art

[0002] The drill bit used as a cutting edge is called a diamond drill bit. This drill bit is an integral drill bit, and there are no movable parts in the whole drill bit. The structure is relatively simple, and it has the capabilities of high strength, high wear resistance and impact resistance. Field use has proved that when the diamond drill bit is drilled in soft-medium hard formations, it has the advantages of fast speed, more footage, long life, stable operation, fewer downhole accidents and good wellbore quality.

[0003] Referring to the comparative document with the publication number of CN113230978A, the present invention relates to the field of diamond drill bit sintering technology, and specifically to a diamond drill bit sintering device and process, including a sintering machine and a special press. A sintering fixed workbench, a sintering lifting workbench and four sintering guide columns are installed in the sintering machine. A pick-and-place plate is installed on one of the four sintering guide columns near the right front side. A cold pressing fixed workbench, a cold pressing lifting workbench and four pressing guide columns are installed in the special press. A feeding plate is installed on one of the four pressing guide columns near the left front side. A plurality of open rings are connected to the pick-and-place plate and the feeding plate. Driving structures and lifting pushing structures are installed on both the sintering machine and the special press. A transfer bridge structure is installed between the sintering machine and the special press. The sintering machine is equipped with a blanking structure. It improves the manufacturing level, reduces the production cost, has a relatively high degree of automation and production efficiency, and is relatively practical.

[0004] When sintering a diamond drill bit, diamond powder generally needs to be put into a mold and then flattened. Generally, the flattening work usually needs to be completed manually. Manual flattening is time-consuming and laborious, affecting the sintering efficiency. At the same time, before sintering the diamond drill bit, it is necessary to ensure the cleanliness of the mold surface. If the mold is not clean and there are impurities attached to the surface, such as the filler stone powder accidentally spilled on the mold surface, the stone powder or other impurities will react at high temperature during sintering, affecting the sintering. At the same time, after the drill bit is sintered, only when the temperature of the mold surface drops to a suitable temperature for the worker to pick up can the production of the next drill bit start. Since the temperature of the mold surface is very high during the processing, and there is no cooling mechanism in the comparative document, the required cooling time is relatively long, and new drill bits cannot be processed during the cooling time, thus reducing the work efficiency and being inconvenient to use.

[0005] How to invent a drill bit sintering device with good flattening effect to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0044] Refer to Figures 3-7 For wiping mechanism: Wiping boxes 101 are arranged on the left and right sides of the sintering table 1. A heat reaction cavity 107 is fixedly connected to the top of the wiping box 101. Mercury is arranged on the inner side wall of the heat reaction cavity 107.

The sintering furnace 112 is located inside the sintering table 1. A jacking spring 110 is arranged inside the sintering furnace 112. A sliding tray 114 is arranged on the jacking spring 110;

[0045] The drill bit mold 103 is arranged on a sliding tray 114, a heating element 113 is arranged at the bottom of the sintering furnace 112, the inner wall of the wiping box 101 is slidably connected with a connecting rod 104, the end of the connecting rod 104 passes through the outside of the wiping box 101, the end of the connecting rod 104 is fixedly connected with a wiping piece 102, the wiping piece 102 is arranged in an arc shape, and the curvature of the wiping piece 102 itself is adapted to the surface curvature of the drill bit mold 103, the tail of the connecting rod 104 is fixedly connected with a contact spring 105, and the outer wall of the connecting rod 104 is fixedly connected with a driving plate 106.

[0046] The working principle of this drill bit sintering device with good flattening effect:

[0047] Before sintering the diamond drill bit, the operator can pour diamond powder into the drill bit mold 103. After pouring, the operator can turn on the telescopic motor 202 to make the telescopic motor 202 drive the telescopic rod 205 to extend downward. When the telescopic rod 205 extends downward, it will drive the mounting plate 204 to move downward. When the mounting plate 204 moves downward, the smaller lower layer of the flattening circular plate 208 will enter the drill bit mold 103 to compact the diamond powder in the drill bit mold 103. As the telescopic rod 205 continues to extend downward, the elastic support rod 207 in the flattening groove 206 will shrink, and the drill bit mold 103 will be pressed down by the flattening circular plate 208, so that the drill bit mold 103 is squeezed and moved into the sintering furnace 112, and the drill bit mold 103 is pressed and moved into the sintering furnace 112. The sliding tray 114 overcomes the elastic force of the lifting spring 110 and moves downward. When the drill mold 103 moves downward, the wipers 102 contacting the surfaces of both sides of the drill mold 103 will contact and wipe the surface of the drill mold 103 to prevent impurities from adhering to the surface of the drill mold 103. When the sliding tray 114 contacts the bottom of the sintering furnace 112, the larger upper layer of the flattened circular plate 208 will block the outlet of the sintering furnace 112 as a whole to prevent hot air from leaking out of the outlet of the sintering furnace 112 during heating. It should be noted that the entire flattened circular plate 208 and the sliding tray 114 are made of high temperature resistant materials. After the outlet of the sintering furnace 112 is blocked, the operator can turn on the heating element 113 to allow the entire sintering furnace 112 to perform high temperature sintering.

[0048] After sintering is completed, the operator can turn off the heating element 113, and then start the telescopic motor 202 again to contract the telescopic rod 205, driving the flattening circular plate 208 to move upward. At this time, without the pressing of the flattening circular plate 208, the elastic force of the jacking spring 110 will jack up the sliding tray 114, causing the drill bit mold 103 to move upward slowly with the flattening circular plate 208. Since the drill bit mold 103 has a relatively high temperature after sintering, when the drill bit mold 103 moves upward, its own high heat will cause the mercury in the heat reaction cavity 107 to undergo a thermal expansion reaction through the heat conduction of the heat absorption block 111, and drive the convex block 109 to push the push rod 108 to move. When the push rod 108 is pushed, it will contact and push the driving plate 106, causing the driving plate 106 to drive the wiping member 102 to contract into the wiping box 101 through the connecting rod 104, avoiding contact with the surface of the drill bit mold 103 and being burned out;

[0049] While the flattened circular plate 208 is slowly moved upward, the top of the drill bit die 103 is always in contact with the flattened circular plate 208. At this time, the relatively high temperature of the drill bit die 103 itself will also be conducted by the heat absorber 210 in the mercury reaction chamber 211, causing the mercury in the mercury reaction chamber 211 to also have a thermal expansion reaction, and causing the push plate 212 to move, so that the contact bump 213 enters the mounting hole 209 through the trigger slot 203. As the telescopic rod 205 continues to contract, the mounting disc 204 will continue to move upward. At this time, the trigger box 304 directly above the mounting hole 209 will enter the mounting hole 209, and the trigger bump 303 on the water outlet baffle 306 will contact and enter the contact bump 213 in the mounting hole 209. When the contact bump 213 contacts the trigger bump 303, it will push the water outlet baffle 306 to the right side of the trigger box 304 along the hypotenuse of the trigger bump 303, and the water delivery hole 307 will be pushed into the water delivery channel 308. At this time, the water originally blocked by the non-perforated part of the water outlet baffle 306 will flow out of the trigger box 304 through the water delivery hole 307 and drip onto the surface of the drill bit die 103 to cool the drill bit die 103. When the surface of the drill bit die 103 drops to the normal temperature, the mercury in the mercury reaction chamber 211 will have a contraction reaction. At this time, the push plate 212 will be pushed back to its original position by the small elastic rod, and the contact bump 213 will retract back into the mercury reaction chamber 211. At this time, without the contact of the contact bump 213, the water outlet baffle 306 will also move leftward back to its original position under the action of the elastic force of the return spring 305. At this time, the water delivery hole 307 in the water delivery channel 308 will be ejected, and the non-perforated part of the water outlet baffle 306 will continue to block the water in the water storage tank 301 to prevent the water from dripping out. When the drill bit die 103 cools down to the normal temperature, it will also cause the mercury in the heat reaction chamber 107 to have a contraction reaction. At this time, under the action of the elastic force of the contact spring 105, the originally inwardly contracted wiping member 102 will be ejected again to contact the surface of the drill bit die 103, facilitating the continuous cleaning of the surface of the drill bit die 103 during the next sintering.

[0050] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0051] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
