Description

Technical Field

[0001] This invention belongs to the field of non-cutting metal machining technology, specifically relating to molds, and more particularly to a flat wire forming mold, forming equipment, and method of use. Background Technology

[0002] Flat wire needs to be pressed and shaped during the production process. The bottom surface of the area of ​​the lower mold used to hold the flat wire is not flat. Therefore, when the upper mold presses down to form the flat wire, the part of the flat wire that is not on the flat surface will sink more under pressure, causing the flat wire to curl up and fail to meet the forming requirements.

[0003] Therefore, due to the technical problem that flat wires will warp under pressure during the forming process, making it impossible to meet the forming requirements, it is necessary to design a flat wire forming mold, forming equipment, and usage method.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0005] This disclosure provides at least one flat wire forming mold, forming equipment, and method of using it.

[0006] In a first aspect, embodiments of this disclosure provide a flat wire forming mold, comprising: The lower mold has a receiving area on its top surface for accommodating flat wire, and a pair of positioning components are provided on one side of the receiving area; The bottom surface of the receiving area has a recessed area, and the positioning component is positioned close to the recessed area; The upper mold has a pressing part on its bottom surface that corresponds to the receiving area; After the flat wire is placed in the receiving area, the flat wire in the receiving area is pressed down by the pressing part of the upper mold to form the flat wire, and the positioning component contacts the outer wall of the flat wire when pressing the flat wire.

[0007] In one alternative implementation, the positioning component includes: a rotating column; The rotating column is rotatably mounted on the top surface of the lower mold and positioned close to the recessed area; The side wall of the rotating column is provided with a limit block, and part of the limit block extends out of the side wall of the rotating column; When the upper mold presses down, it drives the rotating column to rotate, so that the side of the limiting block that extends out of the rotating column contacts the outer wall of the flat wire.

[0008] In one optional embodiment, a groove is provided on the side wall of the rotating column, and a portion of the limiting block is located within the groove and is slidably connected to the groove; A spring is provided between the inner wall of the groove and the limiting block; The portion of the limiting block extending out of the groove is provided with a chamfer; When the upper mold presses down to drive the rotating column to rotate, the guide angle contacts the outer wall of the flat wire, causing the limiting block to retract into the groove and compress the spring. When the side of the limiting block extending out of the rotating column contacts the outer wall of the flat wire, the spring causes the limiting block to press against the flat wire.

[0009] In one optional embodiment, a spiral groove is formed on the outer wall of the rotating column, the top end of the spiral groove is open, and the spiral grooves of the two rotating columns are in opposite directions. The bottom surface of the upper mold is provided with a recess corresponding to the rotating column, and a protrusion is provided in the recess; When the upper mold is pressed down, the protrusion enters the corresponding spiral groove, thereby driving the corresponding rotating column to rotate.

[0010] In one alternative embodiment, the rotating column is connected to the lower mold via a torsion spring; The top surface of the lower mold is provided with an installation block, and the side wall of the installation block is provided with a limiting plate corresponding to the rotating column. The side wall of the limiting block outside the rotating column is in contact with the limiting plate.

[0012] Secondly, embodiments of this disclosure also provide a molding apparatus, comprising: The driving device, and the aforementioned flat wire forming mold; The driving device is connected to the flat wire forming mold to drive the flat wire forming mold to extrude the flat wire, thereby forming the flat wire.

[0013] In one alternative embodiment, the driving device is connected to the top surface of the upper mold in the flat wire forming mold; The driving device is adapted to drive the upper mold to press down the flat wire in the lower mold.

[0014] Thirdly, this disclosure also provides a method of using the above-described flat wire forming mold, comprising: After the flat wire is placed in the receiving area, the flat wire in the receiving area is pressed down by the pressing part of the upper mold to form the flat wire, and the positioning component contacts the outer wall of the flat wire when pressing the flat wire.

[0015] In one alternative embodiment, when the upper mold is pressed down to drive the rotating column to rotate, the guide angle contacts the outer wall of the flat wire, causing the limiting block to retract into the groove and compress the spring, so that when the side of the limiting block extending out of the rotating column contacts the outer wall of the flat wire, the limiting block is pressed against the flat wire by the spring.

[0016] The beneficial effects of this invention are as follows: the flat wire forming mold includes: a lower mold, the top surface of which has a receiving area for accommodating the flat wire, and a pair of positioning components are provided on one side of the receiving area; a recessed area is provided on the bottom surface of the receiving area, and the positioning components are provided close to the recessed area; an upper mold, the bottom surface of which has a pressing part corresponding to the receiving area; after the flat wire is placed in the receiving area, the pressing part of the upper mold presses down on the flat wire in the receiving area, thereby forming the flat wire, and when pressing the flat wire, the positioning components contact the outer wall of the flat wire, thereby limiting the flat wire during the pressing and forming process and preventing the flat wire from curling up.

[0025] Flat wire needs to be pressed and shaped during the production process. The bottom surface of the area of ​​the lower mold used to hold the flat wire is not flat. Therefore, when the upper mold presses down to form the flat wire, the part of the flat wire that is not on the flat surface will sink more under pressure, causing the flat wire to curl up and fail to meet the forming requirements.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, at least one other disclosed embodiment provides a flat wire forming mold, including: a lower mold 1, the top surface of which has a receiving area 11 for receiving a flat wire 4, and a pair of positioning components 2 are provided on one side of the receiving area 11; a recessed area 12 is provided on the bottom surface of the receiving area 11, and the positioning components 2 are provided close to the recessed area 12; an upper mold 3, the bottom surface of which has a pressing part 31 corresponding to the receiving area 11; after the flat wire 4 is placed in the receiving area 11, the pressing part 31 of the upper mold 3 presses down on the flat wire 4 in the receiving area 11, so that the flat wire 4 is formed, and when pressing the flat wire 4, the positioning components 2 contact the outer wall of the flat wire 4, thereby realizing the limiting of the flat wire 4 during the pressing and forming process, and preventing the flat wire 4 from lifting.

[0029] In this embodiment, during the forming process of the flattened wire 4, the positioning component 2 contacts the side wall of the flattened wire 4 to limit the flattened wire 4, so that when the flattened wire 4 located in the recessed area 12 is pressed into the recessed area 12, the other end of the flattened wire 4 is prevented from sticking out.

[0030] like Figure 4 As shown, in an optional embodiment, the positioning component 2 includes: a rotating column 21; the rotating column 21 is rotatably disposed on the top surface of the lower mold 1 and is disposed near the recessed area 12; a limiting block 22 is provided on the side wall of the rotating column 21, and a portion of the limiting block 22 extends out of the side wall of the rotating column 21; when the upper mold 3 is pressed down, the rotating column 21 is driven to rotate, so that the side of the limiting block 22 extending out of the rotating column 21 contacts the outer wall of the flat wire 4.

[0031] In this embodiment, the two positioning components 2 rotate in opposite directions, for example, one rotates clockwise and the other rotates counterclockwise, so that the corresponding limiting block 22 gradually approaches the flat wire 4 during rotation, and finally one side of the limiting block 22 contacts the side wall of the flat wire 4, thus completing the limiting of the flat wire 4. Furthermore, by having one side of the limiting block 22 contact the side wall of the flat wire 4, surface-to-surface contact is achieved, which can ensure the limiting effect.

[0032] like Figure 5As shown, in one optional embodiment, a groove 23 is provided on the side wall of the rotating column 21, and a portion of the limiting block 22 is located in the groove 23 and is slidably connected to the groove 23; a spring 27 is provided between the inner wall of the groove 23 and the limiting block 22; a guide angle 24 is provided on the portion of the limiting block 22 that extends out of the groove 23; when the upper mold 3 is pressed down to drive the rotating column 21 to rotate, the guide angle 24 contacts the outer wall of the flat wire 4, causing the limiting block 22 to retract into the groove 23 and compress the spring 27, so that when the side of the limiting block 22 that extends out of the rotating column 21 contacts the outer wall of the flat wire 4, the spring 27 causes the limiting block 22 to press against the flat wire 4.

[0033] In this embodiment, the spring 27 ensures that the limiting block 22 presses against the flat wire 4 when it contacts the flat wire 4, thus ensuring the limiting effect.

[0034] In this embodiment, by setting a guide angle 24, as the rotating column 21 rotates and drives the limiting block 22 to gradually approach the flat wire 4, when the guide angle 24 contacts the flat wire 4, the corner of the limiting block 22 will not get stuck with the side wall of the flat wire 4, so that the rotating column 21 can rotate smoothly and the surface of the limiting block 22 contacts the side wall of the flat wire 4. When the guide angle 24 of the limiting block 22 contacts the side wall of the flat wire 4, the limiting block 22 can be squeezed into the groove 23 to compress the spring 27, so that one side of the limiting block 22 can smoothly contact the side wall of the flat wire 4.

[0035] like Figure 3 and Figure 4 As shown, in one optional embodiment, a spiral groove 25 is provided on the outer wall of the rotating column 21, the top end of the spiral groove 25 is open, and the spiral grooves 25 of the two rotating columns 21 are in opposite directions; a recess 32 corresponding to the rotating column 21 is provided on the bottom surface of the upper mold 3, and a protrusion 33 is provided in the recess 32; when the upper mold 3 is pressed down, the protrusion 33 enters the corresponding spiral groove 25 to drive the corresponding rotating column 21 to rotate.

[0036] In this embodiment, by setting the spiral groove 25, the upper mold 3 can cause the rotating column 21 to rotate during the pressing process. The top opening of the spiral groove 25 facilitates the entry of the protrusion 33 into the spiral groove 25, so that the spiral groove 25 can rotate.

[0037] In this embodiment, the spiral grooves 25 of the two rotating columns 21 are in opposite directions so that the two rotating columns 21 rotate in opposite directions when the upper mold 3 is pressed down.

[0038] In one optional embodiment, the rotating column 21 is connected to the lower mold 1 by a torsion spring; the top surface of the lower mold 1 is provided with a mounting block 13, and the side wall of the mounting block 13 is provided with a limiting plate 14 corresponding to the rotating column 21, and the side wall of the limiting block 22 located outside the rotating column 21 contacts the limiting plate 14.

[0039] In this embodiment, when the upper mold 3 is not pressed down, the torsion spring drives the rotating column 21 to rotate towards the corresponding limiting plate 14, so as to ensure that the side wall of the limiting block 22 outside the rotating column 21 contacts the limiting plate 14, thereby positioning the top opening of the spiral groove 25. When the upper mold 3 is pressed down, it ensures that the protrusion 33 can smoothly enter the corresponding spiral groove 25.

[0040] In this embodiment, the top end of the rotating column 21 can be conical, making it easy to extend into the corresponding recess 32.

[0041] like Figure 4 As shown, in one optional embodiment, the groove 23 stores lubricating oil; the limiting block 22 has an oil outlet hole 26 on one side that contacts the flat wire 4, and the oil outlet hole 26 communicates with the groove 23.

[0042] In this embodiment, when the limiting block 22 rotates closer to the flat wire 4, and when the limiting block 22 is squeezed and retracts into the groove 23, the lubricating oil in the groove 23 is squeezed out from the oil outlet 26 to be applied to the outer wall of the flat wire 4.

[0043] In this embodiment, the groove 23 can be connected to an external oil tank via an oil passage to replenish lubricating oil into the groove 23. A solenoid valve can be installed in the oil passage. When lubricating oil needs to be replenished, the solenoid valve opens, allowing lubricating oil to enter the groove 23. Then the solenoid valve closes, causing the limiting block 22 to be squeezed and contracted into the groove 23, which can squeeze the lubricating oil in the groove 23 out of the oil outlet 26.

[0044] At least one other disclosed embodiment also provides a forming apparatus, including: a driving device and the above-described flat wire forming mold; the driving device is connected to the flat wire forming mold to drive the flat wire forming mold to extrude the flat wire 4, thereby forming the flat wire 4.

[0045] In one alternative embodiment, the driving device is connected to the top surface of the upper mold 3 in the flat wire forming mold; the driving device is adapted to drive the upper mold 3 to press down the flat wire 4 in the lower mold 1.

[0046] At least one other disclosed embodiment also provides a method of using the flat wire forming mold described above, comprising: placing the flat wire 4 in the receiving area 11, pressing the flat wire 4 in the receiving area 11 by the pressing part 31 of the upper mold 3 to form the flat wire 4, and contacting the outer wall of the flat wire 4 by the positioning component 2 when pressing the flat wire 4.

[0047] In one alternative embodiment, when the upper mold 3 is pressed down to drive the rotating column 21 to rotate, the guide angle 24 contacts the outer wall of the flat wire 4, causing the limiting block 22 to retract into the groove 23 and compress the spring 27, so that when the side of the limiting block 22 extending out of the rotating column 21 contacts the outer wall of the flat wire 4, the limiting block 22 is pressed against the flat wire 4 by the spring 27.

[0048] In one alternative embodiment, when the upper mold 3 is not pressed down, the side wall of the limiting block 22 located outside the rotating column 21 contacts the limiting plate 14.

[0049] In summary, this flat wire forming mold includes: a lower mold 1, the top surface of which has a receiving area 11 for receiving the flat wire 4, and a pair of positioning components 2 are provided on one side of the receiving area 11; a recessed area 12 is provided on the bottom surface of the receiving area 11, and the positioning components 2 are located close to the recessed area 12; an upper mold 3, the bottom surface of which has a pressing part 31 corresponding to the receiving area 11; after the flat wire 4 is placed in the receiving area 11, the pressing part 31 of the upper mold 3 presses down on the flat wire 4 in the receiving area 11, so that the flat wire 4 is formed, and when pressing the flat wire 4, the positioning components 2 contact the outer wall of the flat wire 4, thereby limiting the flat wire 4 during the pressing and forming process and preventing the flat wire 4 from lifting.
