Description

Technical Field

[0001] The utility model relates to an extrusion molding device for a connection terminal, belonging to the technical field of equipment for manufacturing contact components. Background Art

[0002] Transformers are basic equipment for power transmission and distribution, and are widely used in industries, agriculture, transportation, urban communities, and other fields. They are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings. The terminal block is a component used to connect the internal coil of the transformer with the external conductor of the transformer. The terminal block mainly includes an inner connecting plate at both ends, an outer connecting plate, and a conductive rod in the middle, which needs to have good conductivity. The inner connecting plate is connected to the low-voltage end of the internal winding of the transformer, the outer connecting plate is connected to the external conductive component, and the outside of the conductive rod is usually fixed with an insulator.

[0003] In the existing terminal processing technology, in order to improve the conductive performance of the terminal, an integrated manufacturing method is usually adopted, such as a terminal processing method and a stamping die (i.e., a forming assembly) disclosed in the Chinese invention patent application with application publication number CN107895874A and application publication date 2018.04.10, the forming assembly includes an upper forming part and a lower forming part. By setting an avoidance structure at a position corresponding to the conductive rod in the middle of the forming assembly, and using the end faces of the upper and lower forming parts that receive the two ends of the copper rod as the stamping parts for stamping the connecting plate part, the stamping forming assembly can simultaneously stamp out the connecting plates at both ends of the copper rod, thereby obtaining a terminal with an integrated structure. However, since the stamping parts of the upper and lower forming parts in the forming assembly are both planes, it is impossible to limit the material flow direction after the copper rod is pressed, and it is also impossible to ensure the shape of the connecting plate obtained by stamping, so it is necessary to cut and trim the stamped connecting plate to obtain the required connecting plate structure. This not only leads to low production efficiency, but also wastes materials and increases production costs. Utility Model Content

[0004] The utility model aims to provide a terminal extrusion molding device to solve the problem that the upper molding part and the lower molding part of the existing terminal extrusion molding device only extrude the workpiece through a plane, resulting in unrestricted flow of material of the connecting plate during the molding process, and further requiring cutting and trimming, resulting in low production efficiency and high production cost.

[0005] In order to achieve the above-mentioned purpose, the terminal extrusion molding device in the utility model adopts the following technical scheme:

[0006] A wire terminal extrusion forming device includes an upper forming assembly and a lower forming assembly. An upper forming cavity is provided on the upper forming assembly, and a lower forming cavity is provided on the lower forming assembly. When the upper and lower forming assemblies are docked, the upper forming cavity and the lower forming cavity jointly form a forming cavity for forming the wire terminal. The lower forming cavity includes a first lower plate cavity for forming the first connecting plate of the wire terminal, a second lower plate cavity for forming the second connecting plate of the wire terminal, and a lower rod cavity that is communicated with both the first lower plate cavity and the second lower plate cavity and is used for forming the rod-shaped structure of the wire terminal. The lower forming assembly further includes a blanking mechanism for ejecting the formed wire terminal out of the lower forming cavity.

[0007] The beneficial effects of the above technical solution are as follows: The utility model belongs to an improved invention. By setting a forming cavity for forming the wire terminal in the wire terminal extrusion forming device, when the forming assembly extrudes both ends of the copper rod, the material flow is restricted, and it is directly formed into the required connecting plate shape, without the need to cut and trim the connecting plate anymore, thereby improving the production efficiency. At the same time, the material utilization rate is also improved, and the production cost is reduced. In addition, since a lower forming cavity is provided in the lower forming assembly, the extruded and formed wire terminal will be in close contact with the lower forming cavity, making it very inconvenient to manually take. Therefore, by setting a blanking mechanism in the lower forming assembly, the stamped wire terminal can be ejected from the lower forming cavity, facilitating the discharging.

[0008] Furthermore, the upper forming cavity includes a first upper plate cavity for forming the first connecting plate of the wire terminal, a second upper plate cavity for forming the second connecting plate of the wire terminal, and an upper rod cavity that is communicated with both the first upper plate cavity and the second upper plate cavity and is used for forming the rod-shaped structure of the wire terminal.

[0009] Furthermore, the volume of the first upper plate cavity is equal to that of the first lower plate cavity, the volume of the second upper plate cavity is equal to that of the second lower plate cavity, and the volume of the upper rod cavity is equal to that of the lower rod cavity.

[0010] Furthermore, the blanking mechanism includes a first ejector rod arranged corresponding to the first lower plate cavity and a second ejector rod arranged corresponding to the second lower plate cavity.

[0011] Furthermore, the rod diameters of the first ejector rod and the second ejector rod are the same and each is provided with more than two. The number of the first ejector rods is greater than that of the second ejector rods.

[0012] Furthermore, the blanking mechanism includes a pushing component and a first guide rod and a second guide rod that are fixedly connected or in a pushing and matching relationship with the pushing component. The lower forming assembly includes a lower forming plate and a lower connecting plate located below the lower forming plate. The lower forming cavity is arranged on the lower forming plate. The first guide rod and the second guide rod both penetrate through the lower connecting plate and are in a guiding cooperation with the lower connecting plate. The first ejector rod is fixed on the top surface of the first guide rod, and the second ejector rod is fixed on the top surface of the second guide rod.

[0013] Further, the lower forming assembly includes a lower backing plate located between the lower forming plate and the lower connecting plate. The lower forming plate, the lower backing plate, and the lower connecting plate are fixedly connected. Annular flanges are respectively provided at the upper ends of the first guide rod and the second guide rod. The lower backing plate is provided with a first guide hole for receiving the first guide rod and guidingly cooperating with it, and a second guide hole for receiving the second guide rod and guidingly cooperating with it.

[0014] Further, the lower forming assembly further includes a positioning plate located below the lower connecting plate and a support plate fixed between the positioning plate and the lower connecting plate. There are two support plates arranged in parallel at intervals. The pushing assembly includes a pushing plate located between the two support plates and a pushing rod arranged below the pushing plate and guidingly cooperating with the positioning plate. The upper end of the pushing rod is used to push the pushing plate, and the lower end is used to connect the power mechanism.

[0015] Further, the pushing plate includes an upper pushing plate and a lower pushing plate arranged up and down and fixedly connected.

[0016] Further, at least two guide columns for guiding the pushing plate up and down are provided between the lower connecting plate and the positioning plate. Description of the Drawings

[0026] The features and performance of the present utility model will be further described in detail below in conjunction with embodiments.

[0027] In view of the technical problems existing in the prior art, the basic technical concept of the present utility model is: in a terminal extrusion forming device, an upper forming cavity and a lower forming cavity are respectively arranged in an upper forming assembly and a lower forming assembly, and the upper forming cavity and the lower forming cavity can enclose a forming cavity for forming a terminal. The lower forming cavity includes a first lower plate cavity for forming a first connecting plate of the terminal, a second lower plate cavity for forming a second connecting plate of the terminal, and a lower rod cavity for forming a rod-shaped structure of the terminal and communicating with both the first lower plate cavity and the second lower plate cavity. When in use, the forming cavity can restrict the material flow direction of the copper bar after being pressed, so that the two ends of the copper bar can be directly extruded into the required connecting plate shape without trimming the connecting plate again, effectively improving the production efficiency and raw material utilization rate and reducing the production cost. In addition, since the extruded terminal will be in close contact with the lower forming cavity and is inconvenient to manually take, a material ejecting mechanism is arranged in the lower forming assembly to eject the stamped terminal from the lower forming cavity for convenient discharging.

[0028] An embodiment of the terminal extrusion forming device in the present utility model:

[0029] As Figures 1-6 shown, the terminal extrusion forming device includes an upper forming assembly and a lower forming assembly. The upper forming assembly includes an upper connecting plate 1, an upper backing plate 2, and an upper forming plate 3 arranged in sequence from top to bottom. The three plates are fixedly connected together by upper connecting screws 4, and a plurality of upper connecting screws 4 are provided. In this embodiment, there are 6. The lower forming assembly includes a lower forming plate 6, a lower backing plate 7, and a lower connecting plate 8 arranged in sequence from top to bottom. The three plates are fixedly connected together by lower connecting screws 9, and a plurality of lower connecting screws 9 are provided. In this embodiment, there are 6.

[0030] As shown Figure 7 in the figure, a lower forming plate 6 is provided with a lower forming cavity, and the lower forming cavity includes a first lower plate cavity 25, a second lower plate cavity 26 and a lower rod cavity 27. As shown Figure 8 in the figure, an upper forming plate 3 is provided with an upper forming cavity, and the upper forming cavity includes a first upper plate cavity 28, a second upper plate cavity 29 and an upper rod cavity 30. When the upper and lower forming components are buckled, as shown Figure 3 and Figure 6 in the figure, the upper forming cavity and the lower forming cavity can form a forming cavity for the terminal. Among them, the first lower plate cavity 25 and the first upper plate cavity 28 are used to form the first connecting plate of the terminal (not shown in the figure), the second lower plate cavity 26 and the second upper plate cavity 29 are used to form the second connecting plate of the terminal (not shown in the figure), and the lower rod cavity 27 and the upper rod cavity 30 are used to form the conductive rod part of the terminal (not shown in the figure). The forming cavity can limit the flow direction of the material after being pressed, so that the material can be directly formed into the required shape. In this embodiment, the volumes of the upper forming cavity and the lower forming cavity are equal, and the extrusion effect is the best at this time. The raw material can flow into the upper forming cavity and the lower forming cavity at the same time, and the upper forming cavity and the lower forming cavity simultaneously complete the extrusion forming of the raw material, and the forming is more uniform and the efficiency is higher.

[0031] As shown Figure 5 in the figure, two first guide rods 5 are arranged in the upper forming plate 3. In this embodiment, the two first guide rods 5 are symmetrically arranged in the upper forming plate 3. The first guide rods 5 respectively pass through the corresponding through holes in the upper forming plate 3 and the lower forming plate 6, and are inserted into the corresponding through holes in the lower backing plate 7, and the first guide rods 5 are respectively in guiding cooperation with the lower forming plate 6 and the lower backing plate 7. The first guide rods 5 can provide precise guidance for the buckling of the upper and lower forming components. As shown Figure 2 and Figure 5 in the figure, a positioning plate 10 is arranged below the lower connecting plate 8, and a support plate 17 is arranged between the lower connecting plate 8 and the positioning plate 10. The lower connecting plate 8, the support plate 17 and the positioning plate 10 are fixedly connected by second fixing screws 18. Two support plates 17 are arranged and are arranged in parallel at intervals. The support plate 17 can fix and position the lower connecting plate 8 and the positioning plate 10.

[0032] As shown Figure 3 and Figure 6 in the figure, guide columns are arranged between the lower connecting plate 8 and the positioning plate 10. In this embodiment, the guide columns are set as a first guide column 14 and a second guide column 15. Two first guide columns 14 are arranged, both of which are located between the lower connecting plate 8 and the positioning plate 10, and are fixed to the positioning plate 10 by third fixing screws 16. Two second guide columns 15 are arranged, and respectively pass through the positioning plate 10 and the pushing plate 12 and are fixed to the lower connecting plate 8.

[0033] The lower forming assembly further includes a blanking mechanism for ejecting the formed part in the lower forming cavity, facilitating taking. As Figure 3 , Figure 4 and Figure 6 shown, the blanking mechanism includes a second guide rod 19 and a third guide rod 20. Both the second guide rod 19 and the third guide rod 20 include an upper annular flange and a lower rod portion. At positions corresponding to the second guide rod 19 and the third guide rod 20 on the lower backing plate 7, a first guide hole 31 and a second guide hole 32 are respectively provided. The first guide hole 31 and the second guide hole 32 are respectively in guiding cooperation with the annular flanges of the second guide rod 19 and the third guide rod 20. The rod portions of the second guide rod 19 and the third guide rod 20 respectively penetrate through the through holes on the lower connecting plate 8 and are in guiding cooperation with the corresponding through holes.

[0034] As Figure 3 and Figure 6 shown, the tops of the second guide rod 19 and the third guide rod 20 are respectively fixedly connected with a first ejector rod 21 and a second ejector rod 22. The lower ends of the first ejector rod 21 and the second ejector rod 22 are respectively located in the first guide hole 31 and the second guide hole 32, and the upper ends of the first ejector rod 21 and the second ejector rod 22 are respectively located in the first through hole 23 and the second through hole 24. And during the extrusion process, the tops of the first ejector rod 21 and the second ejector rod 22 are flush with the lower forming cavity. In this embodiment, two first ejector rods 21 are provided, four second ejector rods 22 are provided, and the sizes of the first ejector rod 21 and the second ejector rod 22 are the same. When setting the ejector pins for directly ejecting the workpiece, since the middle part of the forming cavity corresponds to the rod-shaped structure of the terminal, it is not convenient to eject through the ejector rod, and the top of the ejector rod also needs to be set as an arc surface, so the corresponding ejector rod size is larger, which makes the aperture of the through hole on the lower forming assembly larger, resulting in a reduction in the strength of the lower forming assembly. Therefore, the positions of the first ejector rod 21 and the second ejector rod 22 respectively correspond to the lower parts of the first lower plate cavity 25 and the second lower plate cavity 26, and pass through the first through hole 23 and the second through hole 24 to contact the first connecting plate and the second connecting plate respectively. During use, the two guide rods can drive the first ejector rod 21 and the second ejector rod 22 to move upward, pass through the first through hole 23 and the second through hole 24 to eject the terminal in the lower forming cavity, facilitating taking. At the same time, the setting of the second guide rod 19 and the third guide rod 20 can reduce the length of the corresponding ejector rod, thereby improving the strength of the ejector rod during use and extending its service life.

[0035] As Figure 3 , Figure 4 and Figure 6 shown, the bottoms of the second guide rod 19 and the third guide rod 20 are in pushing cooperation with a pushing assembly, and the pushing assembly includes a pushing plate 12. As Figure 2As shown, the push plate 12 is located between two support plates 17. The support plates 17 can provide space for the assembly and operation of the push plate 12, facilitating the arrangement of the push plate 12. As Figure 4 shown, the push plate 12 includes an upper push plate 121 and a lower push plate 122 arranged vertically. The upper push plate 121 and the lower push plate 122 are fixedly connected by a first fixing screw 13. By setting the push plate as two fixedly connected plates, it is convenient to adjust the total thickness of the push assembly. For example, when the depth of the lower forming cavity increases and the ejector rod cannot completely eject the workpiece from the lower forming cavity, one of the plates can be removed to reduce the total thickness of the push plate, increasing the moving distance of the ejector rod, so that the workpiece can be completely ejected. The push plate 12 is in guiding cooperation with both the first guiding column 14 and the second guiding column 15. The first guiding column 14 and the second guiding column 15 provide precise guidance for the up and down movement of the push plate 12. In this embodiment, two groups of guiding columns are provided to make the movement guidance of the push plate 12 more precise.

[0036] As Figure 3 and Figure 6 shown, the push assembly further includes a push rod 11, and the push rod 11 is arranged below the lower push plate 122. An annular flange is provided at the upper end of the push rod 11, and a guiding hole is provided at the corresponding position on the positioning plate 10. The guiding hole is a stepped hole. The annular flange of the push rod 11 is located in the large-diameter hole above the stepped hole, and the rod part passes through the small-diameter hole below the stepped hole to connect to the power mechanism. During the extrusion process, the top of the push rod 11 is flush with the top of the positioning plate 10. In use, the power mechanism can move the push rod 11 upward along the guiding hole on the positioning plate 10.

[0037] In use: Place the copper bar into the lower forming cavity of the lower forming plate 6. When the upper forming assembly and the lower forming assembly are buckled, the upper forming cavity and the lower forming cavity can form the forming cavity of the terminal. The upper forming assembly and the lower forming assembly extrude both ends of the copper bar. At the same time, the forming cavity restricts the material flow direction of the copper bar, so that both ends of the copper bar are formed into the shape restricted by the forming cavity, and there is no need to cut and trim the formed connecting plate anymore. After the extrusion is completed, start the power mechanism at the bottom of the push rod 11 to move the push rod 11 upward. The push rod 11 pushes the push plate 12 at the top upward. The push plate 12 pushes the second guiding rod 19 and the third guiding rod 20 at the top upward, so that the second guiding rod 19 and the third guiding rod 20 drive the first ejector rod 21 and the second ejector rod 22 at the top upward, so that the first ejector rod 21 and the second ejector rod 22 eject the terminal out of the lower forming cavity, facilitating taking.

[0038] In other embodiments, when setting the upper forming cavity in the forming assembly, the first upper plate cavity and the second upper plate cavity may not be provided. At this time, the volumes of the first lower plate cavity and the second lower plate cavity of the lower forming cavity are enlarged to form the corresponding connecting plates. At the same time, the upper rod cavity and the lower rod cavity are set to larger sizes to form an avoidance structure for avoiding the middle rod-shaped structure of the wiring terminal. During extrusion molding, the copper bar in the lower forming cavity is extruded by the plane corresponding to the connecting plate of the wiring terminal in the upper forming plate. The first lower plate cavity and the second lower plate cavity in the lower forming cavity limit the material flow at both ends of the copper bar, so that both ends of the copper bar are respectively formed into the corresponding connecting plates.

[0039] In other embodiments, when setting the forming cavity, the upper forming cavity and the lower forming cavity may be asymmetrically arranged. For example, the volumes of the first upper plate cavity and the second upper plate cavity of the upper forming cavity are reduced and are less than the volumes of the first lower plate cavity and the second lower plate cavity of the lower forming cavity. At the same time, the lower rod cavity and the upper rod cavity are set as avoidance structures to avoid the middle rod-shaped structure of the wiring terminal, so that the extruded wiring terminal can be ejected from the lower forming cavity. Of course, the volume of the lower forming cavity can also be reduced, the volume of the upper forming cavity is correspondingly increased, and the lower rod cavity and the upper rod cavity are set as avoidance structures to avoid the middle rod-shaped structure of the wiring terminal, so that the extruded wiring terminal can be ejected from the lower forming cavity.

[0040] In other embodiments, the first ejector rod and the second ejector rod in the ejector mechanism can be replaced by an ejector post. The top of the ejector post is set as an arc-shaped concave surface and is consistent with the radian of the middle rod-shaped structure of the wiring terminal. The ejector post is arranged correspondingly below the middle of the middle rod-shaped structure of the wiring terminal, and the bottom of the ejector post is connected to the push plate. During ejection, the top of the ejector post can contact the rod-shaped structure and eject it, thereby ejecting the wiring terminal.

[0041] In other embodiments, when setting the sizes and quantities of the first ejector rod and the second ejector rod, the first ejector rod and the second ejector rod can be set to the same size. At this time, the quantity of the first ejector rod can be the same as that of the second ejector rod. The first ejector rod and the second ejector rod can also be set to different sizes. For example, the size of the first ejector rod is set to be smaller than that of the second ejector rod. At this time, the quantity of the first ejector rod can be the same as that of the second ejector rod or can be greater than that of the second ejector rod. Of course, the size of the first ejector rod can also be set to be larger than that of the second ejector rod.

[0042] In other embodiments, when setting the first guide rod and the second guide rod in the ejector mechanism, the bottoms of the first guide rod and the second guide rod can be fixedly connected to the pushing assembly. The guide rod can also be set to one. In this case, the first ejector rod and the second ejector rod are fixedly connected to the top of the guide rod. Of course, the guide rod can also be not provided. In this case, the first ejector rod and the second ejector rod are directly fixedly connected to the pushing plate. Correspondingly, through holes for guiding and cooperating with the ejector rods are provided on the lower connecting plate and the lower backing plate. When in use, the first ejector rod and the second ejector rod can be directly pushed upward by the pushing plate.

[0043] In other embodiments, when setting the first guide rod and the second guide rod, an annular flange can be not provided at the upper end, so that the upper and lower rod diameters of the guide rod are the same, and the diameters of the corresponding through holes on the lower backing plate are adaptively reduced to be respectively adapted to and guide and cooperate with the corresponding guide rods. The lower backing plate can also be not provided, so that the lower forming assembly is composed of the lower connecting plate and the lower forming plate. In this case, the first guide rod and the second guide rod are respectively located in the corresponding through holes on the lower connecting plate and are respectively in guiding cooperation with the lower connecting plate. When ejecting the material, the first guide rod and the second guide rod can respectively drive the ejector rods fixedly connected to the top to move upward under the cooperation of the corresponding through holes.

[0044] In other embodiments, the support plate can be not provided. In this case, a bracket is provided outside the extrusion molding device. The bottom plate of the bracket is composed of a positioning plate. The lower connecting plate and the positioning plate are both fixedly connected to the side wall of the bracket. The upper forming assembly is in sliding cooperation with both sides of the bracket, so that the upper forming assembly can move downward to be buckled with the lower forming assembly and can be lifted upward. A power rod penetrating through the top plate of the bracket is provided at the top of the bracket. The bottom of the power rod is fixedly connected to the upper forming assembly and can drive the upper forming assembly to move up and down. In other embodiments, the support plate can also be set as a "hui"-shaped plate. In this case, the four side edges of the support plate are respectively located below the four side edges of the lower connecting plate, and the pushing plate is arranged inside the support plate.

[0045] In other embodiments, when setting the pushing plate, the pushing plate can be set as one plate.

[0046] In other embodiments, when setting the guide posts of the pushing plate, only two guide posts can be provided. In this case, the guide posts are arranged between the positioning plate and the lower connecting plate and are respectively fixedly connected to the positioning plate through fixing screws.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
