Technical Field

[0001] The utility model belongs to the technical field of alloy bar production, and particularly relates to a countersunk type alloy bar die structure. Background Art

[0002] Carbide rods are carbide cutting tools suitable for various rough grinding parameters, cutting materials, and non-metallic materials. For traditional automatic and semi-automatic lathes, carbide turning tools, such as micro-diameter drills, micro-diameter milling cutters, PCB drills, and milling cutters, are typically produced by first producing cylindrical rods, then grinding the rods to create step differences, and finally grinding the drills at the tips. This production process has the disadvantage that a significant amount of carbide material is lost during the grinding process, resulting in considerable waste. Furthermore, the diamond grinding wheel assembly also experiences wear and tear during the grinding process, resulting in significant cost and time. Utility Model Content

The countersink groove is no longer a cylinder, but consists of an injection groove that runs through the upper surface of the countersink template, a coarse groove in the middle and a fine groove at the bottom. After changing to a new shape, the weight of each rod is greatly reduced, saving production material costs, and in the subsequent grinding process, the amount of alloy that needs to be ground is reduced, and the corresponding diamond grinding wheel group grinding loss is also reduced, making the multi-position grinder have higher efficiency.

The opposite surfaces of the two countersink templates 4 are each provided with a plurality of semicircular countersink mold grooves, and the two opposite semicircular countersink mold grooves form a completed countersink groove, and the countersink groove is divided into an injection groove that passes through the upper surface of the countersink template 4, a coarse groove in the middle and a fine groove at the bottom. The side of the countersink template 4 is fixedly installed with The threaded block 5 and the side of the fixed frame 3 are rotatably installed with a rotating shaft 6, and a motor 7 is fixedly installed on the side of one of the fixed frames 3. The output shaft of the motor 7 is fixedly connected to the rotating shaft 6 at the same side position, and a bidirectional threaded rod 8 is fixedly installed between the two rotating shafts 6. The two threaded blocks 5 are threadedly installed on the two sections of the threaded outer surface of the bidirectional threaded rod 8. A material receiving box 9 is slidably provided on the upper surface of the base 1, and a number of partitions 10 are fixedly installed on the inner wall of the material receiving box 9. The several partitions 10 divide the interior of the material receiving box 9 into a number of material receiving intervals, and a supporting plate 11 is slidably provided in the material receiving interval, and the supporting plate 11 is located directly below the countersunk groove at the corresponding position.

[0026] By setting the countersink template 4 to be used in conjunction with the bidirectional threaded rod 8 and the threaded block 5, the rotation of the bidirectional threaded rod 8 drives the threaded block 5 to drive the countersink template 4 to move, the two countersink templates 4 are close to each other to achieve mold closing, and away from each other to achieve mold separation. The opposite semicircular countersink mold grooves on the two countersink templates 4 form a countersink groove. The countersink groove is no longer a cylindrical shape, but is composed of an injection groove that passes through the upper surface of the countersink template 4, a coarse groove in the middle and a fine groove at the bottom. After changing to the new shape, the weight of each rod is greatly reduced, saving production material costs. In the subsequent grinding process, the amount of alloy that needs to be ground is reduced, and the corresponding grinding loss of the diamond grinding wheel group is also reduced, making the multi-position sharpener more efficient. By setting up a material receiving box 9 for use with the countersink template 4, the material receiving box 9 can receive the formed products, and the partition 10 is used in conjunction with the supporting plate 11, and products of different sizes can be received separately, and the supporting plate 11 can move up and down and be used in conjunction with the spring 20 to achieve material receiving buffering, and the material receiving box 9 is detachable, which is convenient for material retrieval operation.

[0028] Several trapezoidal plugs 14 are fixedly installed on the lower surface of the material receiving box 9, and a trapezoidal slot is opened on the upper surface of the base 1 for the trapezoidal plugs 14 to be inserted. The trapezoidal plugs 14 are used in conjunction with the trapezoidal slots. The trapezoidal plugs 14 are inserted into the trapezoidal slots, which can facilitate the installation of the material receiving box 9 and avoid the movement between the material receiving box 9 and the base 1 after installation.

[0029] An extension plate 15 is fixedly installed on the side of the material receiving box 9, and a locking rod 16 is slidably installed on the extension plate 15. An operating plate 17 is fixedly installed on the top of the locking rod 16. A locking groove for inserting the locking rod 16 is provided on the upper surface of the base 1. After the material receiving box 9 is inserted into the trapezoidal slot through the trapezoidal insert block 14, the locking rod 16 is inserted into the locking groove, which can realize the installation and locking of the material receiving box 9. The locking structure is simple and easy to operate.

[0030] The outer sleeve of the locking rod 16 is provided with a spring 18, and the two ends of the spring 18 are fixedly connected to the opposite surfaces of the extension plate 15 and the operating plate 17 respectively. The elastic force of the spring 18 can be used to drive the locking rod 16 to be quickly inserted into the lock slot, thereby improving the convenience of the locking operation.

A spring 20 is fixedly installed on the lower surface of the limiting slider 19. The spring 20 is fixedly installed on the inner wall of the limiting slot. The limiting slider 19 slides in the limiting slot to achieve stable movement of the supporting plate 11 and avoid shaking. The elastic force of the spring 20 can play a load-bearing buffering effect to avoid hard impact when the product falls.

[0032] During use, the product material mixture is first injected into the countersink groove between the two countersink templates 4. After pressing and forming, the motor 7 is started to drive the rotating shaft 6 to drive the bidirectional threaded rod 8 to rotate, and then drive the threaded block 5 to drive the countersink template 4 to move. The two countersink templates 4 move away from each other to achieve mold separation, and the pressed product falls onto the supporting plate 11 in the material receiving box 9. After receiving the product, the supporting plate 11 will slide downward through the limit slider 19, and use the spring 20 for material buffering. After use, pull the operating plate 17 so that the operating plate 17 drives the locking rod 16 to move. After the locking rod 16 disengages from the locking groove, the material receiving box 9 is unlocked, and the material receiving box 9 is pulled horizontally so that the material receiving box 9 slides out of the base 1 through the trapezoidal plug block 14 to achieve material removal.
