[0002] Hard alloy green compacts must be sintered to become hard alloy materials. Before sintering, hard alloy green compacts must be placed on a treated graphite boat in a certain way, which is called boat loading. The way of boat loading will directly affect the sintering quality of hard alloy, mainly manifested as bending deformation, and the types include: side bending, front bending, side and front bending, etc. Severe bending deformation will cause product rejection.

[0003] For example, a tooling for loading hard alloy thin long strip product green compacts disclosed in Chinese Patent (CN205147318U) includes a graphite boat. Two parallel graphite bars are installed on the graphite boat. A plurality of product grooves are provided on the opposite surfaces of the two graphite bars. The product grooves of the two graphite bars correspond to each other one by one. The product groove is a through groove that is wider at the top and narrower at the bottom. Both side groove surfaces of the product groove are inclined surfaces. This utility model reduces the influence of the graphite tooling on the carbon content of the product, the boat loading is stable and reliable, the whole structure is simple, the operation is convenient, the deformation of the produced product is very small, the qualified rate is high, there is no need to increase the size of the green compact and subsequent finishing machining, and the production cost is reduced.

[0004] The above solution still has the following technical deficiencies. The above solution is not convenient for adjusting the distance between the two graphite bars. Since the two graphite bars must be kept parallel to ensure that the alloy does not deform during sintering, and the graphite bars are prone to change in angle during placement and movement, and it is difficult to visually identify whether the two graphite bars are parallel, so it is difficult to adjust the graphite bars. Based on this, a tooling for loading alloy green compacts into boats is proposed. Summary of the Utility Model

An installation box 305 is fixed to the end of the limiting rod 303 away from the baffle 304. One end of the limiting rod 303 close to the installation box 305 is fixed to the side of the installation box 305 close to the vertical plate 2. A first bearing seat 306 is fixed to the side of the installation box 305 close to the screw rod 301. The screw rod 301 rotates inside the first bearing seat 306. Placing grooves 307 are formed inside the opposite sides of the two installation boxes 305, and the graphite blocks 7 can be placed in the placing grooves 307.

[0025] In the distance adjustment mechanism 300 of this embodiment, by rotating the first handle 302, the screw rod 301 can be driven to rotate. The screw rod 301 can drive the installation box 305 to move. The limiting rod 303 can limit the installation box 305 by sliding in the through hole. The placing groove 307 is used to facilitate the placement of the graphite blocks 7.

[0026] It should be noted that the installation box 305 is used to facilitate the installation of the clamping mechanism 400. The baffle 304 is used to prevent the limiting rod 303 from detaching from the vertical plate 2. The bottom side of the graphite block 7 is mutually attached to the bottom side of the placing groove 307.

[0027] Please refer to Figure 1 and Figure 4 , To facilitate the clamping of the graphite blocks 7, the clamping mechanism 400 in this embodiment includes a moving rod 401 movably connected inside the top side wall of the installation box 305. A second handle 402 is fixed to the top side of the moving rod 401. A lead screw 403 is fixed to the outer surface of the moving rod 401. A second threaded hole is formed inside the top side wall of the installation box 305, and the lead screw 403 can be threadedly connected to the second threaded hole. The clamping mechanism 400 further includes a clamping plate 404 movably connected inside the placing groove 307. A rubber pad is fixed to the bottom side of the clamping plate 404.

[0029] It should be noted that rotating the second handle 402 can drive the lead screw 403 to rotate. The limiting plate 406 slides in the limiting groove to limit the clamping plate 404.

[0030] The working principle of the above embodiment is as follows:

[0031] When it is necessary to adjust the distance between the two graphite strips 6, rotate the first handle 302. The first handle 302 drives the screw rod 301 to rotate. The screw rod 301 drives the mounting box 305 to move. At the same time, the mounting box 305 drives the limiting rod 303 to slide in the through hole of the vertical plate 2. When the graphite block 7 enters the mounting box 305, stop rotating the first handle 302. Move the second handle 402 downward. The second handle 402 drives the moving rod 401 to move downward. The moving rod 401 drives the clamping plate 404 and the limiting plate 406 to move together. The limiting plate 406 slides in the limiting groove. When the lead screw 403 abuts against the top side of the mounting box 305, rotate the second handle 402. The second handle 402 drives the lead screw 403 to rotate. The lead screw 403 drives the moving rod 401 and the clamping plate 404 to move. The clamping plate 404 clamps the graphite block 7. Then rotate the first handle 302. The first handle 302 drives the mounting box 305 to move. The mounting box 305 drives the graphite strip 6 to adjust the distance. After the adjustment is completed, rotate the second handle 402. The second handle 402 drives the clamping plate 404 to separate from the graphite block 7. Then take away the graphite boat 5 and the graphite strip 6 from the base 1.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
