Description

Technical Field

[0001] The present application relates to the technical field of metal electrode pressing and forming, and in particular to a pressing die assembly for pressing metal electrodes. Background Art

[0002] Metal electrodes are bulk metal raw materials squeezed into block electrodes by mechanical external force, and then multiple block electrodes are welded together to form a columnar structure. The columnar body is used as an electrode for electric melting, and then melted in the furnace to form an ingot-shaped billet, which is then further processed into a product. This raw material processing method is a common production process in metal processing, and also includes the operation process of directly melting the raw materials into ingot-shaped billets at high temperature in a heating furnace.

[0003] The current metal electrode pressing die assembly is as shown in the attached manual. Figure 1 As shown, it includes a forming tank body with an upper filling port and a lower discharge port, a pressing body is enclosed in the filling port, and the top of the pressing body is vertically driven by a hydraulic rod arranged on the upper side. The pressing process of the metal electrode is as follows: the forming tank body is placed on the bottom plate and the bottom discharge port is closed, and then the metal raw material is filled into the forming tank body through the upper filling port ( Figure 2 After filling, the pressing body is driven downward by a hydraulic rod and extends from the filling port into the forming tank body to perform external force pressing and forming of the raw materials filled therein ( Figure 3 As shown in the figure), the inner cavity of the forming tank body is used as the outer mold for forming the metal electrode. After forming, the pressing body is moved upward, and then the forming tank body is lifted up, and the formed metal electrode is separated from the upwardly moved forming tank body under the gravity of the formed metal electrode ( Figure 4 As shown), a single metal electrode block is pressed and formed, and then a plurality of block electrodes are welded and then electro-fused into an ingot-shaped blank.

[0004] At present, in the process of pressing the metal raw materials into block electrodes by the above method, since the pressing body needs to apply a large extrusion force to the filling raw materials in the forming tank body to squeeze the bulk raw materials into a block structure, when a large pressing force is applied, the raw materials in the forming tank body will appear Figure 5 The horizontal arrow in the middle shows that the inner wall of the forming tank is squeezed, that is, the electrode pressed into a block is pressed against the inner wall of the forming tank with a large force, and it is difficult to separate the electrode block from the forming tank smoothly when the forming tank is lifted. Figure 6 As shown in the figure, if the electrode block falls, it will break and affect the smooth forming of the electrode block. It needs to be pressed again, which increases the pressing cost. There are also safety hazards when it falls, and the frequent sliding unloading method also causes excessive wear on the inner wall of the forming tank. Summary of the invention

[0005] In view of the above problems, the present application aims to provide a pressing die assembly for pressing metal electrodes, which realizes the lateral separation between the inner wall of the forming groove and the block electrode during unloading, quickly separates the two, and solves the problem of difficult smooth separation caused by long-term contact friction during vertical separation at present.

[0006] To achieve the above object, the technical solution adopted in the present application is as follows: A pressing die assembly for pressing metal electrodes, including a forming groove body with an upper filling port and a lower unloading port, and a pressing body is hermetically penetrated in the filling port. It is characterized in that: a unloading mechanism for laterally separating from the metal electrode during unloading is arranged on the inner wall of the forming groove body.

[0007] Preferably, the unloading mechanism includes separation plates separately arranged on each inner wall of the forming groove body.

[0008] Preferably, each of the separation plates is arranged in an inclined surface contact structure with the inner wall of the forming groove body.

[0009] Preferably, a connecting plate is detachably assembled at the top of the separation plate and the forming groove body.

[0010] The beneficial effect of the present application is that: by arranging a unloading mechanism on the inner wall of the forming groove body for laterally separating from the metal electrode during unloading, the lateral separation between the inner wall of the forming groove body and the block electrode is realized during unloading, quickly separating the two, solving the problem of difficult smooth separation caused by long-term contact friction during vertical separation at present. Furthermore, the present application realizes the quick separation operation between the forming groove body and the block electrode through this unloading mechanism, and also solves problems such as potential safety hazards existing after the block electrode is suspended together with the forming groove body during unloading.

[0023] In order to enable those of ordinary skill in the art to better understand the technical solution of the present application, the technical solution of the present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Referring to Figures 1-9 A pressing die assembly for pressing metal electrodes as shown, including a forming tank 1 having an upper filler port 1a and a lower discharge port 1b. A pressing body 2 is hermetically inserted in the filler port 1a, and the top of the pressing body 2 is vertically driven by a hydraulic rod provided on the upper side. The pressing process of the metal electrode is as follows: Place the forming tank 1 on the bottom plate and seal the bottom discharge port 1b, and then fill the metal raw material into the forming tank 1 through the upper filler port 1a. After filling, drive the pressing body 2 to move downward through the hydraulic rod and extend into the forming tank 1 from the filler port 1a, and then apply external force to press the filled raw material into shape. The inner cavity of the forming tank 1 serves as the outer mold for the metal electrode to be formed.

[0025] To solve the problem that it is difficult for the metal electrode block to be smoothly separated from the forming tank after press forming, as Figures 7-8As shown, a discharging mechanism is provided on the inner wall of the forming tank body 1 for laterally separating from the metal electrode during the discharging process. After the raw material is pressed into a block structure and the pressing body 2 is moved upward, the inner wall of the forming tank body 1 is laterally separated from the block electrode through the discharging mechanism. Since there is a large vertical separation friction between the block electrode and the inner wall of the forming tank body 1 during the current separation process of the forming tank body 1, it is difficult for the two to separate smoothly. Therefore, the present application uses the discharging mechanism to laterally separate the inner wall of the forming tank body 1 from the block electrode, that is, to quickly separate the two, solving the problem of difficulty in smooth separation caused by long-term contact friction during vertical separation. Furthermore, the present application uses the discharging mechanism to realize the rapid separation operation of the forming tank body 1 and the block electrode, and also solves the safety hazards and other problems that exist after the block electrode is suspended together with the forming tank body 1 during the current unloading.

[0026] Specifically, Figures 7-8 As shown, the unloading mechanism includes a detachment plate 11 which is separately arranged on each inner wall of the forming tank body 1. When the raw material is pressed and formed, the raw material is squeezed by the pressed body 2 and contacts the inner surface of the detachment plate 11. Then, when detaching, due to the large contact friction between the block electrode and the detachment plate 11, the forming tank body 1 on the outside of the detachment plate 11 is lifted up, and the two are preferably in contact with a smooth surface, which can smoothly realize the rapid detachment of the forming tank body 1 and the detachment plate 11, and then directly detach each detachment plate 11 from the block electrode horizontally, and the unloading operation can be successfully completed.

[0027] During the process of the above-mentioned forming tank body 1 being lifted up and separated from the separation plate 11, there is still contact friction between the two within the height range. Therefore, in order to further solve the long-term contact friction, as Figures 7-8 As shown, each of the separation plates 11 is provided with an inclined contact structure with the inner wall of the forming tank body 1. The inclined contact structure makes the inner width of the forming tank body 1 gradually increase downward, and then after the forming tank body 1 is lifted up, it can be quickly and directly separated from the separation plate 11. When the forming tank body 1 continues to be lifted up, it is no longer in contact with the separation plate 11, and then after the forming tank body 1 is raised above the separation plate 11, the separation plate 11 is laterally separated from the block electrode, and the unloading operation is completed.

[0028] In the initial stage of filling, in order to achieve the relative positioning of the release plate 11 and the forming tank body 1 and avoid the free dumping of the release plate 11 and affecting the smooth filling operation, Figure 9As shown, a connecting plate 3 is detachably assembled at the top end of the separating plate 11 and the forming groove body 1. One side of the connecting plate 3 is rotatably connected to the top surface of the forming groove body 1, while the other side is connected to the top surface of the separating plate 11 by passing through a screw rod, thereby realizing the relative positioning of the separating plate 11 and the forming groove body 1 in the initial stage of filling, and thus facilitating the filling of the filler. In the subsequent discharging stage, after disassembling the connecting plate 3 and the separating plate 11, lifting the forming groove body 1 and laterally disassembling the separating plate 11 can complete the discharging operation of the block electrode.

[0029] The principle of this application is as follows: During the pressing operation of the metal electrode, first, the separating plate 11 is connected to the forming groove body 1 through the connecting plate 3 to achieve relative positioning. Then, the metal raw material is filled into the forming groove body 1 through the filling port 1a. After filling, the pressing body 2 is driven by the hydraulic rod to move downward and extend into the forming groove body 1 through the filling port 1a, and then the raw material filled therein is externally pressed into shape.

[0030] During discharging, after disassembling the connecting plate 3 and the separating plate 11, lifting the forming groove body 1 and then laterally disassembling the separating plate 11 can complete the discharging operation of the block electrode.

[0031] The above shows and describes the basic principle, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
