[0001] This utility model relates to the field of cemented carbide processing technology, and in particular to a cemented carbide rod pressing die device. Background Technology
[0002] Cemented carbide rods are also known as cemented carbide round rods or tungsten carbide rods. Simply put, they are tungsten carbide round rods or cemented carbide round rods. Currently, the methods for producing cemented carbide long rods with holes include: powder extrusion, dry bag isostatic pressing, wet bag cold isostatic pressing, and electroporation after sintering. Cemented carbide rods produced by sintering are then pressed into the required shape using molds.
[0003] In the prior art, patent publication number CN212822674U discloses "a mold for manufacturing cemented carbide round bars", which includes side plates, fixed clamping plates, upper punches, lower punches, clamping grooves, and wedge plates. There are two side plates and two fixed clamping plates, arranged vertically and symmetrically. Round bar mold grooves are formed on the opposite sides of each side plate. The two fixed clamping plates are fixed between the two side plates. The lower punch is located between the two side plates and below the round bar mold grooves. The upper punch is located between the two side plates and above the round bar mold grooves. Both side plates and the wedge plates are placed in the clamping grooves, and the clamping force between the two side plates is controlled by the wedge plates.
[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: When pressing cemented carbide rods, workers typically use hand tools to remove the formed rods from the mold, which is time-consuming, labor-intensive, inconvenient, reduces work efficiency, and increases labor intensity, leaving room for improvement.

[0009] The pressing mechanism includes a mounting plate, mold plate one, mold plate two, mold plate three, a horizontal plate, a hydraulic cylinder, and a slider. The same mounting plate is fixedly installed between two support plates. A sliding groove two is opened on the mounting plate, and mold plate one and mold plate two are slidably connected in the sliding groove two. A groove one is opened on mold plate one, and mold plate three is slidably connected in the groove one. One end of mold plate three is fixedly connected to the base. Through the cooperative design between the base, support plate, partition plate, and pressing mechanism, not only can the effect of automatically pressing and forming sintered cemented carbide rods be achieved, but also the effect of automatic material discharge can be realized, improving convenience and efficiency. Moreover, the structure is simple and more practical.
[0010] Specifically, multiple hydraulic cylinders are fixedly mounted on the mounting plate, and horizontal plates are fixedly mounted on the output ends of the multiple hydraulic cylinders.

[0026] Reference Figure 1-4A cemented carbide rod pressing die device includes a base 1 and a pressing mechanism 3;
[0027] Two support plates 2 are fixedly connected to the base 1, and the same pressing mechanism 3 is provided between the two support plates 2. The pressing mechanism 3 is connected to the base 1.
[0028] The pressing mechanism 3 includes a mounting plate 31, a first mold plate 33, a second mold plate 34, a third mold plate 35, a horizontal plate 36, a hydraulic cylinder 37, and a slider 38. The same mounting plate 31 is fixedly installed between the two support plates 2. The mounting plate 31 has a second sliding groove 32, in which the first mold plate 33 and the second mold plate 34 are slidably connected. The first mold plate 33 has a first groove 7, in which the third mold plate 35 is slidably connected. One end of the third mold plate 35 is fixedly connected to the base 1. Through the cooperative design between the base 1, the support plate 2, the partition plate 5, and the pressing mechanism 3, not only can the effect of automatically pressing and forming sintered hard alloy rods be achieved, but also the effect of automatic material discharge can be realized, improving convenience and efficiency. Moreover, the structure is simple and the practicality is higher.
[0029] In this embodiment, a plurality of hydraulic cylinders 37 are fixedly installed on the mounting plate 31. A horizontal plate 36 is fixedly installed on the output end of each of the plurality of hydraulic cylinders 37. The plurality of horizontal plates 36 are connected to the first mold plate 33 and the second mold plate 34 and are used to drive the first mold plate 33 and the second mold plate 34.
[0030] In this embodiment, sliders 38 are fixedly connected to both ends of multiple horizontal plates 36. The multiple sliders 38 are slidably connected to two mold plates 33 and 34 respectively for transmission.
[0031] In this embodiment, the same cemented carbide rod forming groove 9 is provided on the mold plate 1 33, mold plate 2 34 and mold plate 3 35 for qualitative determination of the sintered cemented carbide rod. Multiple sliding grooves 1 8 are provided on both mold plate 1 33 and mold plate 2 34, and multiple sliders 38 slide in the multiple sliding grooves 1 8 for transmission.
[0032] In this embodiment, one of the two support plates 2 is provided with a feed port 4, which corresponds to the cemented carbide rod forming groove 9, so as to facilitate the conveying of the sintered cemented carbide rod to the mold.
[0033] In this embodiment, one of the two support plates 2 is provided with a sliding groove 3, and a partition 5 is slidably connected in the sliding groove 3. The partition 5 corresponds to the cemented carbide rod forming groove 9 and the feed port 4, which can seal one end of the cemented carbide rod forming groove 9 and prevent the sintered cemented carbide rod from extending towards the feed port during the pressing process.
[0034] In this embodiment, a rubber pad 6 is provided on the base 1, and the rubber pad 6 corresponds to the mold plate 35. The base 1 is tilted at a certain angle to play a buffering role.
[0035] In this embodiment, multiple hydraulic cylinders 37 are arranged at equal intervals on the mounting plate 31, so that the mold plate 33 and the mold plate 34 are subjected to uniform force.
[0036] Working principle: During use, through the synchronous drive of multiple hydraulic cylinders 37 and the transmission of multiple horizontal plates 36 and sliders 38, the mold plate 1 33 and mold plate 2 34 slide downwards synchronously in the sliding groove 2 32 for a certain distance, and one end of the mold plate 35 is inserted between the mold plate 1 33 and mold plate 2 34. Then, the sintered alloy rod is transported to the space between the mold plate 1 33, mold plate 2 34 and mold plate 35 through the feed port 4, and the partition plate 5 is inserted into the corresponding sliding groove 3 of the support plate 2. After that, the multiple hydraulic cylinders 37 are started again, so that the mold plate 1 33, mold plate 2 34 and mold plate 35 move closer to each other and press the sintered alloy rod into shape, thereby achieving the effect of pressing the alloy rod in and out.
[0037] Subsequently, through the directional drive of multiple hydraulic cylinders 37, mold plate 1 33 and mold plate 2 34 gradually detach from mold plate 3 35. During this process, when the distance between mold plate 2 34 and mold plate 3 35 is greater than the diameter of the alloy rod after pressing, it falls from mold plate 3 35 onto rubber pad 6, thereby achieving the effect of automatic material handling.
[0038] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the sintered cemented carbide rods be automatically pressed and shaped, but the material discharge can also be automatically achieved, improving convenience and efficiency. Moreover, the structure is simple and the practicality is higher.
