Description

Technical Field

[0001] The utility model relates to the technical field of polycrystalline diamond composite bits, and specifically relates to a production device for polycrystalline diamond composite bits. Background Art

[0002] A polycrystalline diamond composite bit, abbreviated as a PDC bit, is a small cutting block made of polycrystalline diamond, which is formed by being inlaid or sintered onto a bit body. The design of this bit makes it particularly suitable for soft to medium-hard formations. The advantages of PDC bits include long bit life and high dimensional accuracy. Due to their excellent performance, they are widely used in the oil and gas development industry and have become common rock-breaking tools. Their good drilling ability can effectively shorten the drilling cycle and improve work efficiency. In the prior art, when producing polycrystalline diamond composite bits, the bit body adhered with polycrystalline diamond needs to be placed inside a sintering space, and then heating components such as electric heating plates installed on the inner wall of the sintering space are used to heat the sintering space, thereby realizing the sintering of polycrystalline diamond composite bits. However, the positions of the heating components are fixed, and the temperature rises slowly in the places far from the heating components, which easily leads to uneven temperature rise in the sintering space and affects the production quality of polycrystalline diamond composite bits. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects, provide a production device for polycrystalline diamond composite bits, guide hot air to evenly enter the sintering space, ensure uniform temperature rise in the sintering space, accelerate the temperature rise speed of the sintering space, and improve the production quality of polycrystalline diamond composite bits, which can effectively solve the problems in the background art.

[0007] Further, the flow guiding mechanism further includes a first flow guiding hole and a second flow guiding hole. The first flow guiding holes are respectively arranged on the right side surface of the supporting tray, and the air outlet holes II corresponding to the horizontal positions are all communicated with one first flow guiding hole. The second flow guiding holes are respectively arranged on the left side surface of the supporting tray, and the air outlet holes I corresponding to the horizontal positions are all communicated with one second flow guiding hole, so as to guide the flow track of the hot air.

[0008] Further, the flow guiding mechanism further includes a flow guiding inclined plate, which is respectively arranged at the left end of the first flow guiding hole and the right end of the second flow guiding hole, so that the hot air is blown out obliquely.

[0009] Further, the flow guiding mechanism further includes rubber gaskets, which are respectively arranged in the mounting holes on the upper and lower inner walls of the guide rail frame to seal between the guide rail frame and the supporting tray.

[0010] Further, a single-chip microcomputer is arranged on the surface of the sintering box body. The input end of the single-chip microcomputer is electrically connected to an external power supply to control the start and stop of the whole device.

[0012] Further, handles are arranged at the front ends of the supporting trays to facilitate the movement of the supporting trays.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The production equipment of the polycrystalline diamond composite bit has the following advantages:

[0014] The flow track of the hot air is guided, so that the hot air blows out obliquely from the air holes on the surface of the supporting tray from the middle to both sides, so that the hot air uniformly enters the sintering space.

[0022] Please refer to Figures 1-5 , this embodiment provides a technical solution: a polycrystalline diamond composite bit production device, including a sintering box body 1 and a flow guiding mechanism 5;

[0023] Sintering box body 1: Its interior is provided with a sintering cavity 2, which provides space for the sintering of polycrystalline diamond composite bits. The surface of the sintering box body 1 is provided with a single-chip microcomputer 7. The input end of the single-chip microcomputer 7 is electrically connected to an external power source to control the start and stop of the overall device. The lower end of the single-chip microcomputer 7 is provided with a hot air blower 6. The air outlet of the hot air blower 6 is provided with an air inlet pipe 4. The branch pipes of the air inlet pipe 4 respectively pass through the through holes on the left and right inner walls of the sintering cavity 2. The left and right inner walls of the sintering cavity 2 are respectively provided with air outlet holes 3 to provide heat for the sintering of polycrystalline diamond composite bits;

[0024] Flow guiding mechanism 5: It includes a support pallet 51, a first air outlet hole 52, a second air outlet hole 53 and a guide rail frame 58. The guide rail frames 58 are respectively arranged on the inner walls of the sintering cavity 2. The support pallet 51 is longitudinally slidably connected inside the guide rail frames 58. The support pallets 51 are all hollow plates. The right ends of the upper surfaces of the support pallets 51 are respectively provided with the first air outlet holes 52 for guiding the hot air to blow out obliquely. The left ends of the upper surfaces of the support pallets 51 are respectively provided with the second air outlet holes 53 for guiding the hot air to blow out obliquely. The flow guiding mechanism 5 further includes a first flow guiding hole 54 and a second flow guiding hole 55. The first flow guiding holes 54 are respectively arranged on the right side surfaces of the support pallets 51. The second air outlet holes 53 corresponding to the horizontal positions are all communicated with one first flow guiding hole 54. The second flow guiding holes 55 are respectively arranged on the left side surfaces of the support pallets 51. The first air outlet holes 52 corresponding to the horizontal positions are all communicated with one second flow guiding hole 55. The flow guiding mechanism 5 further includes a flow guiding inclined plate 56. The flow guiding inclined plates 56 are respectively arranged at the left ends of the first flow guiding holes 54 and the right ends of the second flow guiding holes 55. During the production process, the right ends of the first flow guiding holes 54 and the left ends of the second flow guiding holes 55 are respectively communicated with the branch pipes of the air inlet pipe 4. After the hot air enters the first flow guiding holes 54, it flows leftward. Under the guidance of the flow guiding inclined plate 56, the hot air blows out obliquely from the second air outlet holes 53 from right to left. Similarly, after the hot air enters the second air outlet holes 53, it flows rightward and finally blows out obliquely from the first air outlet holes 52 from left to right, so that the hot air evenly enters the sintering space, and at the same time accurately pushes the original air in the sintering space out from the air outlet holes 3.

[0025] The working principle of a polycrystalline diamond composite bit production device provided by the present utility model is as follows: When in use, the bit adhered with polycrystalline diamond is placed on the surface of the support pallet 51. The hot air blower 6 is started through the single-chip microcomputer 7. The hot air generated by the hot air blower 6 is discharged through the branch pipes of the air inlet pipe 4. At this time, the right ends of the first flow guiding holes 54 and the left ends of the second flow guiding holes 55 are respectively communicated with the branch pipes of the air inlet pipe 4. After the hot air enters the first flow guiding holes 54, it flows leftward. Under the guidance of the flow guiding inclined plate 56, the hot air blows out obliquely from the second air outlet holes 53 from right to left. Similarly, after the hot air enters the second air outlet holes 53, it flows rightward and finally blows out obliquely from the first air outlet holes 52 from left to right, so that the hot air evenly enters the sintering space, and at the same time accurately pushes the original air in the sintering space out from the air outlet holes 3. The heat carried by the hot air is used to heat the bit adhered with polycrystalline diamond, and the polycrystalline diamond is fixed on the bit through sintering to produce the polycrystalline diamond composite bit.

[0026] It should be noted that, in the above embodiments, the single-chip microcomputer 7 can be selected as the PIC16F1823-I / P model single-chip microcomputer, and the hot air blower 6 can be freely configured according to the actual application scenario. It is recommended to select the HAM-G3A-11 model hot air blower. The single-chip microcomputer 7 controls the hot air blower 6 to work by using the methods commonly used in the prior art.
