Description

Technical Field

[0001] The utility model relates to the technical field of continuous extrusion forming, in particular to an extrusion forming die and a device. Background Art

[0002] Continuous extrusion is an advanced material forming technology that utilizes the friction between the deformed metal and the tool to achieve continuous extrusion through an annular channel formed by a rectangular cross-section groove on the rotating extrusion wheel and a fixed die base. This method does not require external heating because the heat generated by friction is sufficient to heat the metal to the required extrusion temperature.

Therefore, it cannot be understood as a limitation on the present invention.

[0055] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0056] Please refer to Figures 1-4 , Figure 1 An exploded schematic diagram of the extrusion die 100 provided in this embodiment from a first perspective; Figure 2 A schematic structural diagram of the extrusion die 100 provided in this embodiment from a second viewing angle; Figure 3 A schematic structural diagram of the extrusion die 100 provided in this embodiment from a third viewing angle; Figure 4 1 is a cross-sectional view of the first module 110 and the second module 120 provided in this embodiment.

[0057] The utility model provides an extrusion forming device, which includes an extrusion wheel and an extrusion forming die 100; wherein the extrusion forming die 100 includes a first die set 110, a second die set 120 and a forming die set 130; the first die set 110 is provided with a feed channel 112; the second die set 120 is provided with a discharge channel 121; and the forming die set 130 is provided with a forming channel;

[0058] When the first die set 110 , the second die set 120 and the forming die set 130 are in a clamped state, the feed channel 112 , the forming channel and the discharge channel 121 are in communication. The first die set 110 includes a die base 111 and a blocking block 113 .

[0059] The working principle of the extrusion forming device is as follows:

[0060] When the extrusion wheel, the first module 110, the second module 120 and the forming module 130 are in the mold-clamping state, the extrusion wheel and the die base 111 rotate and cooperate to extrude the raw material, so that the temperature of the raw material itself increases and is in a molten state under the action of the mutual extrusion between the extrusion wheel and the first module 110. The raw material moves along the extension direction of the contact surface between the die base 111 and the extrusion wheel. When the raw material moves to the position of the stop block 113, the movement direction of the raw material changes due to the obstruction of the stop block 113, and then enters the feed channel 112, and then enters the forming channel connected to the feed channel 112. In the process of passing through the forming channel, it is transformed according to the shape of the forming channel, and finally the product of the desired shape is output by the discharge channel 121. It should be noted that the raw material in this embodiment is metal wire.

[0061] In this embodiment, the first module 110 and the second module 120 are detachably connected. One or both of the first module 110 and the second module 120 define a receiving cavity 101. The forming module 130 is located within the receiving cavity 101 and is detachably connected to the first module 110 and the second module 120. It will be appreciated that in this embodiment, the first module 110, the second module 120, and the forming module 130 are all detachable. Therefore, when it is necessary to produce products of different shapes, only the forming module 130 needs to be replaced, without having to replace the entire module. This reduces the cost of using the mold and thus improves production efficiency. Furthermore, since there is no need to produce multiple first modules 110 and second modules 120, the cost of mold production is reduced.

[0062] In addition, when one of the first module 110, the second module 120 or the forming module 130 fails, only the structure needs to be replaced, which is more conducive to subsequent maintenance and cleaning and reduces maintenance costs.

[0063] It should be noted that in this embodiment, both the first module 110 and the second module 120 are provided with cavities, and the two cavities are connected, thereby forming a receiving cavity 101 when the first module 110 and the second module 120 are connected. In other embodiments, the receiving cavity 101 may be provided only in the first module 110 or the second module 120 to accommodate the shaping module.

[0064] For further information, please refer to Figures 1-4 The forming module 130 is provided with a limiting portion 131 , which cooperates with the inner wall of the accommodating cavity 101 ; the limiting portion 131 is used to limit the forming module 130 from rotating around the forming channel.

[0065] Specifically, the shaping die is fan-shaped, with the stopper 131 being a flat surface. This surface mates with the inner wall of the feed channel 112, preventing the shaping die 130 from rotating about its axis as the raw material enters the shaping channel, which could result in an irregular product shape. Thus, by providing a stopper to secure the shaping die 130, the product quality rate is guaranteed.

[0066] Furthermore, the present invention includes multiple forming modules 130, and any one of the multiple forming modules 130 is accommodated in the accommodating cavity 101. In this embodiment, the multiple forming modules 130 are used to form products of different shapes. If, after completing the processing of a product of one shape, another product of a different shape needs to be processed, the forming module 130 can be replaced to continue processing the product of the other shape, thereby reducing the use cost, improving production efficiency, and improving the efficiency of subsequent maintenance and cleaning.

[0067] Based on the above configuration, this embodiment provides three types of forming modules 130, including a flat module 140, a tube module 150, and a wire module 160. It should be noted that in addition to the three types of modules provided in this embodiment, other forming modules such as special-shaped modules can also be used, or forming modules 130 that are configured differently from this embodiment but still produce the same shape can also be used.

[0068] Please refer to Figures 1-6 , Figure 5 An exploded schematic diagram of the flat panel module 140 provided in this embodiment; Figure 6 A cross-sectional view of an extrusion forming die 100 provided in this embodiment.

[0069] The flat panel module 140 includes an adjusting member 141, an extending member 142, a flow blocking member 143, a flat panel shaping member 144, and a flat panel protective member 145, which are sequentially stacked in a first direction. The flat panel protective member 145 has a first receiving groove 1452, and the flat panel shaping member 144 is detachably received in the first receiving groove 1452. The adjusting member 141 has an adjusting hole 1411. The extending member 142 has an extending hole 1421. The flow blocking member 143 has a blocking hole 144. Flow hole 1431; the flat plate shaping part 144 is provided with a flat plate shaping hole 1441; the flat plate protective part 145 is provided with a flat plate avoidance hole 1451; when the first module 110, the second module 120 and the flat plate module 140 are in the mold closing state, the adjustment hole 1411, the extension hole 1421, the flow blocking hole 1431, the flat plate shaping hole 1441 and the flat plate avoidance hole 1451 are connected to each other, and are connected to the feed channel 112 and the discharge channel 121.

[0070] It can be understood that after the flat plate modules 140 are stacked one after another, the axes of the adjustment hole 1411, the extension hole 1421, the flow blocking hole 1431, and the flat plate shaping hole 1441 coincide with each other. After passing through the feed channel 112, the raw material will sequentially pass through the adjustment hole 1411, the extension hole 1421, the flow blocking hole 1431, the flat plate shaping hole 1441, and the flat plate avoidance hole 1451; then, it will enter the discharge channel 121 and be discharged from the discharge channel 121. The adjustment hole 1411, the extension hole 1421, the flow blocking hole 1431, the flat plate shaping hole 1441, and the flat plate avoidance hole 1451 form the shaping channel of the flat plate module 140.

[0071] It should be noted that the adjustment hole 1411, the extension hole 1421 and the flow-blocking hole 1431 are all used to adjust the shape of the raw material. After the raw material passes through the flat forming hole 1441 of the flat forming member 144, its shape no longer changes, and a flat product is formed.

[0072] Flat plate shaping member 144 is housed within first receiving groove 1452 and protected by flat plate guard 145 to prevent wear and tear, thereby ensuring product quality. Furthermore, flat plate shaping member 144 is removable. Since flat plate shaping member 144 rubs against the raw material to shape it, if worn, maintenance can be completed by simply replacing flat plate shaping member 144, thereby improving maintenance efficiency and saving costs.

[0073] The cross-sectional area of ​​the flat plate avoidance hole 1451 in the second direction increases along the first direction; the projection of the flat plate shaping hole 1441 in the first direction lies within the outlines of the flow-blocking hole 1431 and the flat plate avoidance hole 1451. As can be understood, the flat plate avoidance hole 1451 gradually expands along the first direction to prevent contact between the product and the flat plate guard 145, preventing the flat plate guard 145 from hindering the product's movement and causing wear on the product, thereby ensuring product quality.

[0074] It should be noted that the first direction is the movement direction of the raw material in the forming channel.

[0075] The flat plate module 140 is provided with an adjusting member 141 , an extending member 142 and a flow blocking member 143 to stabilize the flow rate of the raw material, thereby preventing the product from being unable to form a desired shape due to unstable metal flow and improving the qualified rate of the product.

[0076] Specifically, the cross-sectional areas of adjustment hole 1411 and extension hole 1421 in the second direction increase along the first direction, thereby increasing the amount of raw material entering the forming channel. Because the flow rate at both ends of the raw material is lower than that in the center, flow blocking hole 1431 is provided. The width of the cross-sectional area in the second direction of flow blocking hole 1431 is smaller in the middle than at the ends. The first and second directions are perpendicular to each other to balance the flow rates at various locations, thereby ensuring product quality.

[0077] It can be understood that the projections of the adjustment hole 1411 and the flow blocking hole 1431 in the first direction are located within the outline of the extension hole 1421; the projection of the flat plate shaping hole 1441 in the first direction is located within the outlines of the flow blocking hole 1431 and the flat plate avoidance hole 1451;

[0078] Based on the above settings, please refer to Figures 1-6 The adjustment member 141 further includes a positioning portion 1412 , which surrounds the outer edge of the contour of the adjustment hole 1411 ; at least a portion of the positioning portion 1412 extends into the feed channel 112 and cooperates with the feed channel 112 .

[0079] Therefore, when installing the flat plate module 140 , the installation position can be positioned by the positioning portion 1412 so that the adjustment hole 1411 , the extension hole 1421 , the flow blocking hole 1431 , the flat plate shaping hole 1441 and the flat plate avoidance hole 1451 can be connected to the feed channel 112 .

[0080] It should be noted that the cross-sectional shapes of the adjustment hole 1411, the extension hole 1421, the flat plate shaping hole 1441 and the flat plate avoidance hole 1451 in the second direction are all square, while the cross-sectional shape of the flow blocking hole in the second direction is two square shapes, thus making the product a flat plate structure.

[0081] Please refer to Figures 1-8 , Figure 7 An exploded schematic diagram of the pipe module 150 provided in this embodiment; Figure 8 A cross-sectional view of another extrusion die 100 provided in this embodiment.

[0082] The pipe module 150 includes a dividing piece 151, a welding piece 152, a pipe shaping piece 153 and a pipe protection piece 154 which are stacked in sequence along a first direction; the pipe protection piece 154 is provided with a second accommodating groove, and the pipe shaping piece 153 is detachably accommodated in the second accommodating groove; the dividing piece 151 is provided with a dividing portion 1511 and two arc-shaped holes 1512; the welding piece 152 is provided with a welding hole 1521; the pipe shaping piece 153 is provided with a pipe shaping hole 1531; the pipe protection piece 154 is provided with a pipe avoidance hole 1541; when the first module 110, the second module 120 and the pipe module 150 are in a mold closing state, the two arc-shaped holes 1512, the welding hole 1521, the pipe shaping hole 1531 and the pipe avoidance hole 1541 are connected to each other, and are all connected to the feed channel 112 and the discharge channel 121.

[0083] Similarly, after the raw material passes through the tube shaping hole 1531 of the tube shaping member 153, its shape does not change and it becomes a tubular product. In addition, the two arc holes 1512, the welding hole 1521, the tube shaping hole 1531 and the tube avoidance hole 1541 serve as the forming channels of the tube module 150.

[0084] The pipe protection member 154 protects the pipe shaping member 153, preventing wear and tear caused by friction between the pipe shaping member 153 and the inner wall of the accommodating chamber 101. Furthermore, the cross-sectional area of ​​the pipe avoidance hole 1541 in the second direction gradually increases along the first direction, ensuring that products passing through the pipe avoidance hole 1541 do not come into contact with the pipe protection member 154, thus preventing wear and tear and improving product qualification rates.

[0085] Moreover, after the split piece 151 , the welding piece 152 , the pipe shaping piece 153 and the pipe protection piece 154 are stacked together in sequence, the axis of the welding hole 1521 , the axis of the pipe shaping hole 1531 and the axis of the pipe avoidance hole 1541 coincide with each other.

[0086] In this embodiment, two arc-shaped holes 1512 are arranged circumferentially around the dividing portion 1511. Because the raw material in this embodiment is a solid metal wire, and the desired tubular structure is hollow, the dividing portion 1511 is provided to divide the wire into two portions. Each portion passes through an arc-shaped hole 1512, thus forming two arc-shaped structures.

[0087] The two arcuate structures then move to welding hole 1521. Because the cross-sectional area of ​​welding hole 1521 in the second direction gradually decreases along the first direction, the distance between the two arcuate structures gradually decreases, and the two arcuate structures come into contact. Because the metal is molten in the forming channel, the two arcuate structures weld together after contact, forming a hollow structure. The arcuate structures then continue to move to tube shaping hole 1531 to form a tubular structure.

[0088] It can be understood that the projection of the tube shaping hole 1531 in the first direction is located within the contours of the welding hole 1521 and the tube avoidance hole 1541; the cross-sectional area of ​​the tube avoidance hole 1541 in the second direction gradually increases along the first direction.

[0089] It should be noted that the cross-sections of the welding holes 1521 , the tube shaping holes 1531 and the tube avoidance holes 1541 on the second square are circular, so that the product has a tube structure.

[0090] Based on the above, please refer to Figures 1-8 The dividing portion 1511 includes a first portion and a second portion. The first portion protrudes in a first direction toward the feed channel 112 and extends into the feed channel 112. The first portion is spaced from the inner wall of the feed channel 112. Specifically, the first portion is hemispherical. By providing the raised first portion, the raw material is pre-divided in the feed channel 112, thereby ensuring that the solid structure can be transformed into a hollow structure.

[0091] The second portion protrudes along the first direction toward the welding hole 1521 and extends into the welding hole 1521. The cross-section of the second portion in the second direction gradually decreases along the first direction. The second portion is spaced apart from the inner wall of the welding hole 1521. This prevents the two arc-shaped structures from being welded together prematurely and becoming a solid structure, thereby improving the product qualification rate.

[0092] Please refer to Figures 1-10 , Figure 9 An exploded schematic diagram of the wire module 160 provided in this embodiment from a first perspective; Figure 10 This is a schematic exploded view of the wire module 160 provided in this embodiment from a second perspective.

[0093] The wire module 160 includes an adjusting member 161, a wire shaping member 162 and a wire protection member 163 which are stacked in sequence along a first direction; the wire protection member 163 is provided with a third accommodating groove, and the wire shaping member 162 is accommodated in the third accommodating groove; the adjusting member 161 is provided with an adjusting hole 1611; the wire shaping member 162 is provided with a wire shaping hole 1621; the wire protection member 163 is provided with a wire avoidance hole 1631; when the first module 110, the second module 120 and the wire module 160 are in a mold closing state, the adjusting hole 1611, the wire shaping hole 1621 and the wire avoidance hole 1631 are connected to each other, and are all connected to the feed channel 112 and the discharge channel 121.

[0094] The cross-sectional area of ​​the adjustment hole 1611 in the second direction gradually decreases along the first direction; the cross-sectional area of ​​the wire avoidance hole 1631 in the second direction gradually increases along the second direction; the projection of the wire shaping hole 1621 in the first direction is located within the contours of the adjustment hole 1611 and the wire avoidance hole 1631.

[0095] Similarly, the adjustment hole 1611, the wire shaping hole 1621, and the wire avoidance hole 1631 form the forming channel of the wire module 160. After the adjustment member 161, the wire shaping member 162, and the wire protection member 163 are stacked together, the axis of the adjustment hole 1611, the axis of the wire shaping hole 1621, and the axis of the wire avoidance hole 1631 coincide.

[0096] The adjusting member 161 is used to adjust the speed of the raw material during forming to ensure that the product shape is regular. The wire guard 163 is used to protect the wire shaping member 162. The wire avoidance hole 1631 is used to prevent the product from contacting the wire guard 163 and causing wear, thereby ensuring the product qualification rate.

[0097] It should be noted that the cross-sectional shape of the adjusting hole 1611 , the wire shaping hole 1621 and the wire avoiding hole 1631 in the second direction is circular to form the wire.

[0098] In light of the above, when the raw material needs to be processed into a flat plate structure, the flat plate module 140 is placed in the accommodating chamber 101 to process the flat plate product. When the desired number of flat plate products is reached, it is necessary to stop processing the flat plate product and proceed to processing the pipe or wire material. In this way, the shape and structure of the processed product can be changed by replacing the flat plate module 140 with the pipe module 150 or the wire module 160, eliminating the need to replace the entire module, thereby reducing operating costs and improving production efficiency.

[0099] For further information, please refer to Figures 1-11 , Figure 11 This is a schematic diagram of the structure of the filler 132 provided in this embodiment. The extrusion die 100 also includes a filler 132, which is detachably connected to the forming die 130 and the second die 120. The filler 132 defines a through hole 1321, which communicates with the forming channel and the discharge channel 121. The projection of the forming channel in the first direction is located within the outline of the through hole 1321.

[0100] Specifically, the number of components required for the three aforementioned forming modules 130, namely, the flat plate module 140, the tube module 150, and the wire module 160, varies. However, the volume of the accommodating chamber 101 remains unchanged. To fill the accommodating chamber 101, a filler 132 is provided to ensure that the accommodating chamber 101 is completely filled by the forming module 130. This ensures that, after the forming module 130 is installed, the accommodating chamber 101 is disconnected from the feed channel 112 and the discharge channel 121. This prevents raw materials from entering the accommodating chamber 101 and causing its shape to change, thereby ensuring a satisfactory product quality.

[0101] Furthermore, the through hole 1321 can allow products of various shapes to pass through, thereby preventing the filling member 132 from hindering the movement of the products and preventing friction between the products and the filling member 132 from causing wear of the products.

[0102] It is understood that the forming module 130 is composed of a combination of multiple structural components, with different forming modules 130 having different combinations of specific structural components. In this embodiment, each structural component in the forming module 130 is also provided with a positioning protrusion 133 and a positioning groove 134, which are located on opposite sides. The positioning protrusion 133 of a single structural component cooperates with the positioning groove 134 of an adjacent structural component to accurately position the installation of multiple structural components, thereby ensuring the qualified rate of the product.

[0103] In summary, the extrusion forming mold 100 includes a first module 110, a second module 120 and a forming module 130; the first module 110 and the second module 120 are detachably connected, and one or both of the first module 110 and the second module 120 are provided with a accommodating cavity 101; the forming module 130 is located in the accommodating cavity 101 and is detachably connected to the first module 110 and the second module 120; the first module 110 is provided with a feed channel 112; the second module 120 is provided with a discharge channel 121; the forming module 130 is provided with a forming channel; when the first module 110, the second module 120 and the forming module 130 are in a mold closing state, the feed channel 112, the forming channel and the discharge channel 121 are connected.

[0104] If a flat-plate product is to be produced, the flat-plate module 140 is installed in the accommodating chamber 101. The material first flows through the adjustment hole 1411 on the adjustment member 141, the extension hole 1421 on the extension member 142, and the flow-blocking hole 1431 on the flow-blocking member 143 to adjust the shape of the material and stabilize the flow of the material; then, the material flows through the flat-plate shaping hole 1441 on the flat-plate shaping member 144 to form a flat-plate product.

[0105] When the desired number of flat-plate products is reached and tubular products need to be produced, the flat-plate module 140 in the extrusion die 100 can be replaced with the tubular module 150. After the replacement is completed, the material continues to enter through the feed channel 112, is squeezed by the dividing portion 1511 on the dividing member 151, flows through the arc-shaped hole 1512, then enters the welding hole 1521 on the welding member 152 to be welded into a hollow tube, and finally flows through the tube shaping hole 1531 on the tube shaping member 153 to form a tubular product.

[0106] Similarly, when the desired number of tubular products is reached and wire production is required, the tube module 150 in the extrusion die 100 can be replaced with the wire module 160. After the replacement is completed, the material continues to enter the feed channel 112, first flowing through the adjustment hole 1611 on the adjustment member 161, and then through the wire shaping hole 1621 on the wire shaping member 162 to form the wire.

[0107] When replacing different forming modules 130 , since different forming modules 130 have different structural quantities, when replacing the flat module 140 with a larger structural quantity with the pipe module 150 with a smaller structural quantity, the extra space in the accommodating cavity 101 can be filled by adding a filler 132 .

[0108] The extrusion die 100 detachably connects the forming module 130 to the first module 110 and the second module 120, allowing the forming module 130 to be directly replaced when a product of a different shape is required, rather than replacing the entire die. This reduces the cost of using the die and improves production efficiency. Since the manufacturing cost of the die is relatively high, only the corresponding forming module 130 needs to be produced for replacement, thereby reducing manufacturing costs. Furthermore, since the first module 110, the second module 120, and the forming module 130 are all detachable, subsequent maintenance and cleaning of the extrusion die 100 is facilitated.

[0109] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
