Description

Technical Field

[0001] This utility model relates to the field of electrical assembly technology, and in particular to a device for hard wire forming of a circuit breaker conductive system. Background Technology

[0002] During the production and processing of circuit breakers, the hard wires of the circuit breaker's conductive system need to be bent into a certain shape before they can be connected and installed with other components of the circuit breaker. Currently, the hard wire forming of circuit breakers has always been done using manual clamps. However, the manual method of bending the hard wires using clamps results in inconsistent product dimensions that deviate significantly from technical requirements. Furthermore, it cannot guarantee the consistency of the formed hard wires, making circuit breaker assembly difficult and affecting product quality and production efficiency.

[0003] To improve production efficiency, hard wire forming devices for circuit breaker conductive systems have been developed. However, existing hard wire forming devices can only bend the conductors at a 90° angle. This means that existing devices cannot bend the conductors at small angles (less than 90°), resulting in non-standard conductor dimensions that do not fit well with the magnetic ring. Consequently, circuit breaker assembly becomes difficult, affecting product quality and production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing hard wire forming devices for circuit breaker conductive systems cannot bend conductors at small angles. This invention provides a hard wire forming device for circuit breaker conductive systems that can bend conductors at small angles, thereby enabling the processed conductors to better fit with the magnetic ring, improving the quality and production efficiency of circuit breakers.

[0005] To solve the above-mentioned technical problems, the present invention discloses a hard wire forming device for a circuit breaker conductive system, comprising: a forming base having a wire mounting groove thereon, wherein a wire can be installed in the wire mounting groove, the wire mounting groove comprising a first groove and a second groove connected in sequence, the first groove and the second groove being connected by a non-vertical bottom wall, the depth of the second groove being greater than the depth of the first groove; a pressing forming device disposed above the forming base, the pressing forming device having a pressing block and a pressing forming plate; the pressing block being positioned corresponding to the first groove, the pressing block being used to contact the wire in the first groove; the pressing forming plate being positioned corresponding to the second groove, the pressing forming plate being used to contact the wire in the second groove and press the wire down to contact the bottom wall of the second groove.

[0006] By adopting the above technical solution, firstly, since the shallower first groove and the deeper second groove are connected by a non-vertical bottom wall, the pressing and forming action can be completed directly within the wire mounting groove when the pressing and forming device shapes the wire to be processed placed in the wire mounting groove, without needing to extend the wire to be processed beyond the end of the wire mounting groove. Secondly, since the connecting bottom wall of the first and second grooves is not vertical, the bending angle of the wire to be processed during pressing and forming will not be 90°, but a small angle bend less than 90°. During this process, the pressure block can press and fix the wire to be processed in the wire mounting groove, making it less likely for the wire to fall off, shake, or warp during the bending process of the pressing and forming device. The pressing and forming plate can perform a small angle bend on the wire to be processed placed in the second groove, so that the formed wire can be adapted to the magnetic ring, thereby improving the installation efficiency and product quality of the circuit breaker.

[0007] According to another specific embodiment of the present invention, it further includes: a longitudinal forming device, which is arranged vertically relative to the wire mounting groove; a transverse forming device, which is arranged parallel to the wire mounting groove; a pressing forming device including a pressing driving member, which is driven to be connected to a pressing forming plate, and the pressing forming plate is in contact with the wire surface; a longitudinal forming device including a longitudinal forming plate driven to be connected by a longitudinal driving member, and the longitudinal forming plate is in contact with the wire surface; a transverse forming device including a transverse forming plate driven to be connected by a transverse driving member, and the transverse forming plate is in contact with the wire surface.

[0008] The circuit breaker conductive system hard wire forming device provided by this utility model, employing the above technical solution, further includes a longitudinal forming device and a transverse forming device. The pressing forming device, longitudinal forming device, and transverse forming device can sequentially bend the conductor to be processed, fixed in the conductor mounting groove, in three different directions during a single forming process, so that the produced formed conductor can be adapted to the magnetic ring. The circuit breaker conductive system hard wire forming device of this utility model has a simple structure and produces conductors with consistent dimensions and specifications after processing, thereby improving the product qualification rate.

[0009] According to another specific embodiment of the present invention, the second groove includes a concave arc-shaped bottom wall and a second straight bottom wall. The concave arc-shaped bottom wall is a non-vertical bottom wall. The end of the pressing forming plate includes an arc segment and a second straight segment in sequence. The arc segment corresponds to the position of the concave arc-shaped bottom wall, and the second straight segment corresponds to the position of the second straight bottom wall.

[0010] By adopting the above technical solution, on the one hand, by setting the shape of the end of the pressing forming plate to match the shape of the second groove, it can be ensured that the shape of the wire after forming is consistent with the required shape; on the other hand, when the pressing forming device presses down, the pressing block first presses the wire to be processed; then, the pressing forming plate is pressed into the second groove, and the depth of the second straight segment inserted into the second straight bottom wall is greater than the depth of the arc segment inserted into the concave arc bottom wall. Therefore, the bending angle of the wire formed by pressing is a small angle.

[0011] According to another specific embodiment of the present invention, the bottom wall of the first groove is a first straight bottom wall, the first straight bottom wall and the second straight bottom wall are connected by an inwardly concave arc bottom wall, and the end of the pressing forming plate also includes a first straight segment, the first straight segment corresponding to the position of part of the first straight bottom wall.

[0012] Using the above technical solution, the pressure block and the first straight segment correspond to the position of the first groove. Under the combined action of the pressure block, the first straight segment, and the first groove, the wire to be processed in the first groove becomes a straight segment after forming. Under the combined action of the arc segment and the concave arc bottom wall, the wire to be processed above the concave arc bottom wall becomes an arc segment after forming. Under the combined action of the second straight segment and the second straight bottom wall, the wire to be processed above the second straight bottom wall becomes a straight segment after forming. That is, after forming, the wire to be processed consists of connected straight segments, arc segments, and straight segments, with a small bending angle.

[0013] According to another specific embodiment of the present invention, the pressing forming device includes a pressing mold base, and the pressing block is elastically connected to the pressing mold base to adjust the distance between the lower surface of the pressing block and the lower surface of the pressing mold base.

[0014] By adopting the above technical solution, the pressure block can, on the one hand, press the wire in the guide mounting groove to prevent the end of the wire to be processed from sticking up. On the other hand, the distance between the lower surface of the pressure block and the lower surface of the lower pressing mold base is adjustable, which makes it easy to adjust the distance between the lower surface of the pressure block and the wire mounting groove so that it is compatible with the wire to be processed. Thus, the pressure block and the lower pressing forming plate work together to make the wire forming more accurate.

[0015] According to another specific embodiment of the present invention, the pressing die base is provided with a first hole and a second hole that are connected. The cross-sectional area of ​​the first hole is larger than that of the second hole. Part of the pressing block is disposed in the first hole and part of the pressing block is disposed in the second hole. A limiting member is provided on the side wall of the pressing block. The limiting member is used to abut against the bottom of the first hole. The pressing forming device also includes: a connecting cover plate covering the first hole; and an elastic member. The two ends of the elastic member abut against the connecting cover plate and the pressing block respectively. The elastic member is used to apply a force to the pressing block so that the lower end of the pressing block protrudes out of the second hole.

[0016] According to another specific embodiment of the present invention, the pressure block is also provided with a blind hole, and the elastic element is provided in the blind hole, and the two ends of the elastic element abut against the connecting cover plate and the blind hole respectively.

[0017] According to another specific embodiment of the present invention, the lower pressure mold base is also provided with an installation groove, the lower pressure forming plate is disposed in the installation groove, and the distance between the upper surface of the lower pressure forming plate and the lower surface of the connecting cover plate is adjustable.

[0018] Using the above technical solution, the relative position of the pressing forming plate and the connecting cover plate can be adjusted, thereby adjusting the depth of the lower end of the pressing forming plate inserted into the second groove, so that the wire to be processed can be processed into the required angle and shape according to actual needs.

[0019] According to another specific embodiment of the present invention, the connecting cover plate is provided with a threaded hole, and the lower pressing mold base also includes an adjusting screw, which is threadedly connected to the threaded hole, and the end of the adjusting screw abuts against the upper surface of the lower pressing forming plate.

[0020] By adopting the above technical solution and setting an adjusting screw, the pressing forming plate can be limited to prevent it from moving upward under excessive pressure, thereby affecting the wire forming effect.

[0021] According to another specific embodiment of the present invention, it further includes: a positioning block, which is disposed on the forming seat, and an opening is provided on one side of the third groove in the extension direction. The positioning block is disposed on one side of the opening and is used to abut against the wire in the third groove. The distance between the positioning block and the end face of the third groove is adjustable.

[0022] The positioning component, when using the above technical solution, limits the length of the wire to be processed extending out of the wire mounting groove, making the formed wire more accurate and improving the reliability of the device.

[0023] According to another specific embodiment of the present invention, a guide member is provided on the lower die base, and a guide groove corresponding to the guide member is provided on the forming base, and the guide member can slide in the guide groove.

[0024] According to another specific embodiment of the present invention, the wire mounting groove further includes a longitudinal forming groove, which is connected to the first groove body and is set at an angle. The longitudinal forming groove includes a bottom wall and a side wall. The lower surface of the pressure block is provided with a limiting surface. The limiting surface and the bottom wall and side wall of the longitudinal forming groove form an inclined groove. The inclined groove has a groove opening, which is opposite to the side wall. The inclined groove is inclined downward relative to the horizontal surface. The longitudinal forming plate is used to press the end of the wire extending out of the first groove body into the longitudinal forming groove.

[0025] Using the above technical solution, the longitudinal forming plate and the longitudinal forming groove work together to bend the wire to be processed in a second direction. On the one hand, when the longitudinal forming plate bends the wire longitudinally, the longitudinal forming groove mainly plays a limiting role, ensuring the stability and accuracy of the wire during bending, so that the wire after longitudinal bending can be accurately positioned in front of the moving direction of the transverse forming device. On the other hand, after the longitudinal forming device completes the longitudinal bending, it stays at this position, providing the bending conditions for transverse bending.

[0026] According to another specific embodiment of the present invention, the lower end of the longitudinal forming plate is connected to a longitudinal guide plate, and the forming base is provided with a longitudinal guide hole, and the longitudinal guide plate can slide in the longitudinal guide hole.

[0027] The longitudinal guide hole extends in a downward-sloping direction relative to the horizontal plane;

[0028] The forming base is also equipped with a baffle, which is located in front of the outlet of the longitudinal guide hole and is used to abut against the end of the longitudinal guide plate;

[0029] The baffle is equipped with a limit screw, which is threadedly connected to the baffle. The end of the limit screw is used to abut against the end of the longitudinal guide plate.

[0030] By adopting the above technical solution, compared with the existing technology that uses linear guide rails for guidance, the sliding of the longitudinal guide plate in the longitudinal guide hole can make the entire device structure more compact and smaller in size; setting a baffle can limit the movement distance of the longitudinal guide plate, thereby controlling the movement distance of the longitudinal forming plate along the longitudinal forming groove, so that the length of the longitudinally formed wire meets the set requirements.

[0031] According to another specific embodiment of the present invention, a transverse forming groove is provided on the transverse forming plate, and the transverse forming groove is used to contact the end of the wire extending out of the longitudinal forming groove.

[0032] The transverse forming plate is provided with a transverse guide plate, and the forming base is provided with a transverse guide hole, which allows the transverse guide plate to slide within the transverse guide hole.

[0033] Using the above technical solution, the transverse forming groove enables the wire to bend in the third direction, and at the same time makes the wire more stable and accurate in the transverse forming process. Compared with the existing technology that uses linear guide rails for guidance, the transverse guide plate sliding in the transverse guide hole can make the entire device structure more compact and smaller in size.

[0062] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0063] The conductors in a circuit breaker's conductive system are mostly solid wires. During circuit breaker assembly, these solid wires need to be bent into a specific shape before they can be assembled with the magnetic ring in the circuit breaker. The bent conductors can then be fitted with the magnetic ring for assembly. Current solid wire forming devices for circuit breaker conductive systems have conductor placement slots for holding the conductors to be processed. These slots are of uniform depth. When the conductor is placed in the slot, the formed end of the conductor must extend completely beyond the end of the slot. This means that when the pressing mechanism presses down vertically, the angle between the bent conductor and the conductor in the slot is 90°. In other words, current solid wire forming devices for circuit breaker conductive systems can only bend the conductor at 90° angles during pressing down, and cannot bend the conductor at smaller angles (bends less than 90°). This results in non-standard conductor dimensions, poor fit with the magnetic ring, and consequently, difficulties in circuit breaker assembly, affecting product quality and production efficiency.

[0064] This utility model discloses a conductor forming device for a circuit breaker's conductive system, which includes a conductor mounting groove. This groove consists of a first groove and a second groove of different depths, connected by a non-vertical bottom wall. The non-vertical bottom wall means that it does not extend vertically, and the angle between the bottom wall and the extending directions of the two end grooves is not 90°. Therefore, when the forming plate is pressed down, it can automatically bend the conductor at a small angle, allowing the formed conductor to fit the magnetic ring, thereby improving the circuit breaker's installation efficiency and product quality.

[0065] Figure 1 This diagram shows the shape of the conductor 1 after being processed by the circuit breaker conductive system hard wire forming device in an embodiment of the present invention. The forming device can process the conductor to be processed (e.g., a straight conductor extending along the X direction) in three different directions (e.g., respectively). Figure 1 The conductor 1 is formed by sequentially bending in the Z, Y, and X directions (where Z is the downward forming direction, Y is the longitudinal forming direction, and X is the transverse forming direction), performing downward bending, longitudinal bending, and transverse bending. The resulting conductor 1 corresponds to a main body 110, a downward bending section 120, a longitudinal bending section 130, and a transverse bending section 140. The downward bending section 120 is located at one end of the main body 110, while the longitudinal bending section 130 and the transverse bending section 140 are located at the other ends of the main body 110. The downward bending section 120 includes a bending segment 121 and a straight segment 122. The bending angle between the bending segment 121 and the main body 110 is as follows: Figure 1 As shown by angle α, which is an acute angle and represents a small-angle bend. For example, angle α can be 15°, 30°, or 45°, etc. The straight line segment 122 does not bend and extends in the same direction as the main body 110.

[0066] The following is combined with Figures 2 to 11 The pressing and forming process of the circuit breaker conductive system hard wire forming device in the embodiments of this application is described by way of example.

[0067] Figure 2 This diagram illustrates the structure of the hard wire forming device for the circuit breaker conductive system in an embodiment of the present invention. Figure 3 A schematic diagram of the molding base 2 in an embodiment of this utility model is shown. Figure 4 It shows Figure 3 Cross-sectional view of the middle forming seat 2. (See figure) Figure 2As shown, the circuit breaker conductive system hard wire forming device in this embodiment includes a forming base 2, a pressing forming device 3, a longitudinal forming device 4, a transverse forming device 5, and a frame base plate 6. The forming base 2, pressing forming device 3, longitudinal forming device 4, and transverse forming device 5 are all mounted on the frame base plate 6. The forming base 2 has a wire mounting groove 21 for placing the wire to be processed. The pressing forming device 3, longitudinal forming device 4, and transverse forming device 5 are used to process and shape the wire placed in the wire mounting groove 21. The pressing forming device 3 is correspondingly arranged to the forming base 2 and is used to press down on the wire to form a pressing bend 120. The longitudinal forming device 4 is vertically arranged relative to the wire mounting groove 21 and is used to longitudinally shape the wire to form a longitudinal bend 130. The transverse forming device 5 is parallel to the wire mounting groove 21 and is used to transversely shape the wire to form a transverse bend 140.

[0068] Further reference Figure 3 and Figure 4 As shown, the wire mounting groove 21 includes a first groove 211 and a second groove 212 that are connected to each other. The first groove 211 and the second groove 212 are connected by a non-vertical bottom wall, and the depth of the second groove 212 is greater than the depth of the first groove 211. Further, the bottom wall of the first groove 211 is a first straight bottom wall 2111, and the second groove 212 includes a second straight bottom wall 2121 and a concave arc-shaped bottom wall 2122. The non-vertical bottom wall is the concave arc-shaped bottom wall 2122. The first straight bottom wall 2111 and the second straight bottom wall 2121 are connected by the concave arc-shaped bottom wall 2122. It should be noted that the first straight bottom wall 2111 and the second straight bottom wall 2121 refer to the extension direction of the bottom wall as shown in the figure. Figure 4 The straight line shown in the X direction, as for the shape of the first straight bottom wall 2111 and the second straight bottom wall 2121, can be either a plane or an arc surface.

[0069] Preferably, since the outer surface of the conductor to be processed is a circumferential surface, in order to improve the compatibility with the conductor, the bottom walls of the first straight bottom wall 2111 and the second straight bottom wall 2121 are both curved surfaces. Furthermore, the extending directions of the two side walls of the first groove 211 are perpendicular to the extending direction of the first straight bottom wall 2111, and the extending directions of the two side walls of the second groove 212 are perpendicular to the extending direction of the second straight bottom wall 2121.

[0070] It should be noted that in this embodiment, the non-vertical bottom wall is a concave arc-shaped bottom wall. Figure 5 A schematic diagram of a modified embodiment of the present invention with a non-vertical bottom wall is shown. (Reference) Figure 5 In other embodiments, the non-vertical bottom wall can be as follows: Figure 5 (a) shows a straight inclined bottom wall 2124, or as shown in the figure. Figure 5 (b) shows the wavy, sloping bottom wall 2125 or as shown in the image. Figure 5 (c) shows the convex arc-shaped bottom wall 2126, etc.

[0071] Furthermore, the wire to be processed can be installed in the wire mounting groove 21. When the wire to be processed is installed in the wire mounting groove 21, one end of the wire to be processed corresponds to the position of the first groove 211 and the second groove 212, and the other end of the wire to be processed extends out of the first groove 211. The portion of the wire to be processed corresponding to the first groove 211 forms the main body 110 after molding. The portion of the wire to be processed corresponding to the second groove 212 forms a downward bending portion 120 after molding. Specifically, the portion corresponding to the concave arc-shaped bottom wall 2122 forms a bent section 121 after molding, and the portion corresponding to the second straight bottom wall 2121 forms a straight section 122 after molding. The portion of the wire to be processed extending beyond the first groove 211 forms a longitudinal bending portion 130 and a transverse bending portion 140 after molding.

[0072] refer to Figure 2 and Figure 4 A pressing forming device 3 is positioned above the forming base 2. The pressing forming device 3 includes a pressing block 31 and a pressing forming plate 32. The pressing block 31 corresponds to the position of the first groove 211 and is used to contact the wire to be processed in the first groove 211 to press and fix the wire. The pressing forming plate 32 corresponds to the position of the second groove 212 and is used to contact the wire in the second groove 212 and press the wire to be processed down to contact the bottom wall of the second groove 212. Under the pressure of the pressing forming plate 32 and the limiting effect of the concave arc-shaped bottom wall 2122 and the second straight bottom wall 2121, the wire to be processed forms a pressed bending portion 120.

[0073] Using the above technical solution, firstly, since the shallower first groove 211 and the deeper second groove 212 are connected by a non-vertical bottom wall, when the pressing forming device 3 shapes the conductor to be processed placed in the conductor mounting groove 21, it can be completed directly in the conductor mounting groove 21 without the conductor to be processed extending out of the end of the conductor mounting groove 21. Secondly, since the connecting bottom wall of the first groove 211 and the second groove 212 is not perpendicular, the bending angle of the conductor during pressing forming will not be 90°, but a bending angle less than 90°. In addition, the pressure block 31 can press and fix the conductor to be processed in the conductor mounting groove 21, making it less likely for the conductor to fall off, shake, or warp during the bending process of the pressing forming device 3. The pressing forming plate 32 can bend the conductor placed in the second groove 212 at a small angle, so that the formed conductor 1 can be adapted to the magnetic ring, thereby improving the installation efficiency and product quality of the circuit breaker.

[0074] Further reference Figure 2 The pressing forming device 3 includes a pressing drive component 33, which is drivenly connected to the pressing forming plate 32. The pressing drive component 33 drives the pressing forming plate 32 in the vertical direction (e.g., Figure 2 The plate moves in the Z direction and the pressing forming plate 32 contacts the surface of the conductor to be processed, so that the conductor to be processed is pressed and bent.

[0075] Figure 6 The structural schematic of the pressing forming plate 32 in an embodiment of this application is shown. Figure 6 In the embodiment of the pressing forming plate 32 shown, the end of the pressing forming plate 32 includes a first straight segment 321, a concave arc segment 322, and a second straight segment 323. The first straight segment 321 corresponds to the position of the first straight bottom wall 2111, the concave arc segment 322 corresponds to the position of the concave arc bottom wall 2122, and the second straight segment 323 corresponds to the position of the second straight bottom wall 2121.

[0076] Furthermore, the pressing forming device 3 includes a pressing die base 34, which is movable in the vertical direction to drive the pressing block 31 and the pressing forming plate 32 to move in the vertical direction. The pressing block 31 is elastically connected to the pressing die base 34 to adjust the distance between the lower surface of the pressing block 31 and the lower surface of the pressing die base 34, thereby adjusting the distance between the lower surface of the pressing block 31 and the wire mounting groove 21 to match the diameter of the wire to be processed.

[0077] Figure 7A A schematic diagram of the structure of the compression molding machine in the compression state is shown. Figure 1 , Figure 7B A schematic diagram of the structure of the compression molding machine in the compression state is shown. Figure 2 , Figure 8A schematic diagram of the conductor 1 after pressing and forming according to this utility model is shown. (Reference) Figure 7A When the pressing mold base 34 moves downward in the vertical direction, the pressing block 31 first contacts the wire to be processed in the wire mounting groove 21 to achieve the pre-clamping action of the wire to be processed. At this time, the end of the pressing forming plate 32 does not contact the wire to be processed in the wire mounting groove 21.

[0078] refer to Figure 7B As the pressing die 34 continues to move downwards vertically until it contacts the forming seat 2, the forming seat 2 applies a reaction force to the pressing block 31, causing the pressing block 31 to retract upwards against the resistance of the elastic element 36. Simultaneously, the second straight segment 323 of the pressing forming plate 32 first contacts the wire to be processed above the second straight bottom wall 2121 and presses this portion of the wire into contact with the second straight bottom wall 2121. Subsequently, the concave arc segment 322 contacts the wire to be processed above the concave arc bottom wall 2122 and presses this portion of the wire into contact with the concave arc bottom wall 2122. The pressing forming plate 32 is in position when the first straight segment 321 contacts the wire in the second groove 212. At this point, the lower surface of the pressing block 31 is flush with the first straight segment 321, and the pressing forming plate 32 has completed the small-angle bending of the wire to be processed. (Reference) Figure 8 The conductor to be processed forms a downward bending section 120. Specifically, as shown... Figure 8 As shown, the bending angle between the extending directions of the main body 110 (that is, the wire in contact with the first straight bottom wall 2111) and the bent segment 121 in the downward bending portion 120 (that is, the wire in contact with the concave arc-shaped bottom wall 2122) is as follows: Figure 8 As shown by angle α, the included angle α is less than 90°, which is a small-angle bend. The extension direction of the straight segment 122 (that is, the wire in contact with the second straight bottom wall 2121) is parallel to the extension direction of the main body 110. In particular, the pressing forming device 3 remains in this position after completing the pressing bend and does not immediately return to its original position, thus providing conditions for subsequent longitudinal and transverse bending.

[0079] By adopting the above technical solution, on the one hand, by setting the shape of the end of the pressing forming plate 32 to match the shape of the second groove 212, it can be ensured that the shape of the formed wire 1 is consistent with the required shape. On the other hand, when the pressing forming device 3 presses down, the pressure block 31 first presses the wire to be processed. Then, the pressing forming plate 32 is pressed into the second groove 212, and the depth of the second straight segment 323 inserted into the second straight bottom wall 2121 is greater than the depth of the concave arc segment 322 inserted into the concave arc bottom wall 2122. Therefore, the bending angle of the wire 1 after pressing and bending is a small angle of less than 90°.

[0080] The specific structure of the pressure mold base 34 in this application is described below with reference to the accompanying drawings.

[0081] Figure 9 and Figure 10 A specific embodiment of the pressure die holder 34 is shown, wherein Figure 9 An exploded view of the lower pressure mold base 34 is shown. Figure 10 It shows Figure 9 A partial sectional view of the middle and lower pressure die holder 34. (See attached image.) Figure 9 and Figure 10 As shown, the pressing die base 34 has a first hole 341 and a second hole 342 that are connected. The cross-sectional area of ​​the first hole 341 is larger than that of the second hole 342. Part of the pressing block 31 is disposed in the first hole 341 and part of the pressing block 31 is disposed in the second hole. The pressing block 31 can slide in the first hole 341 and the second hole 342. For example, the pressing block 31 is a cuboid extending in the vertical direction, and the first hole 341 and the second hole 342 are both rectangular holes extending in the vertical direction. The side wall of the pressing block 31 is provided with a stepped surface 311 (as an example of a limiting member). The stepped surface 311 is used to abut against the connection 3421 of the first hole 341 and the second hole 342 to prevent the pressing block 31 from falling out of the second hole 342. The pressing forming device 3 also includes a connecting cover plate 35 and an elastic member 36. The connecting cover plate 35 is detachably connected above the lower pressure mold base 34 and covers the first hole 341 to prevent the pressure block 31 from falling out from above the first hole 341. Specifically, in this embodiment, the elastic element 36 is a rubber block. The rubber block is disposed above the pressure block 31, and both ends of the rubber block abut against the lower surface of the connecting cover plate 35 and the upper surface of the pressure block 31, respectively. The rubber block is used to apply force to the pressure block 31 so that the lower end of the pressure block 31 protrudes out of the second hole 342.

[0082] The specific structure of the pressing die base 34 in this application embodiment is not limited to this, for example Figure 11 Another specific embodiment of the pressure mold base 34 is shown. In this embodiment, the elastic element 36 is a plurality of connected metal sheets. Exemplarily, the upper end of the metal sheet is parallel to the lower surface of the connecting cover plate 35, and the lower end of the metal sheet is parallel to the upper surface of the pressure block 31. When the upper end of the metal sheet abuts against the lower surface of the connecting cover plate 35, the lower end of the metal sheet can apply a force to the upper surface of the pressure block 31, so that the lower end of the pressure block 31 protrudes out of the second hole 342.

[0083] Alternatively, in some possible implementations, Figure 12Another specific embodiment of the lower pressure mold base 34 is shown. In this embodiment, the elastic element 36 is a compression spring. The pressure block 31 is also provided with a blind hole 312. Exemplarily, there are two blind holes 312 and two compression springs, with each compression spring disposed in one of the two blind holes 312, and each end of the compression spring abutting against the lower surface of the connecting cover plate 35 and the bottom wall of the blind hole, respectively. When the upper end of the compression spring abuts against the lower surface of the connecting cover plate 35, the lower end of the compression spring can apply a force to the upper surface of the pressure block 31, so that the lower end of the pressure block 31 protrudes out of the second hole 342. In this embodiment, by placing the compression spring in the blind hole 312, slippage of the compression spring end can be prevented, thereby improving the stability of the connection.

[0084] Further reference Figure 12 The pressing die base 34 is also provided with a mounting groove 343, in which the pressing forming plate 32 is disposed. Furthermore, the distance between the upper surface of the pressing forming plate 32 and the lower surface of the connecting cover plate 35 is adjustable. Further, the pressing forming plate 32 is provided with a waist-shaped hole 324, and the pressing die base 34 is also provided with a bolt (not shown in the figure), which passes through the waist-shaped hole 324 and is threadedly connected to the pressing die base 34. For example, there are two waist-shaped holes 324 and two bolts. The waist-shaped hole 324 allows adjustment of the relative position of the pressing forming plate 32 and the pressing die base 34, thereby adjusting the depth at which the lower end of the pressing forming plate 32 is inserted into the second groove 212, thus allowing the wire to be processed to the required angle and shape according to actual needs.

[0085] Further reference Figure 12 The connecting cover plate 35 is provided with a threaded hole 351. The lower pressing mold base 34 also includes an adjusting screw 37, which is threadedly connected to the threaded hole 351, and the lower end of the adjusting screw 37 abuts against the upper surface of the lower pressing forming plate 32. By setting the adjusting screw 37, on the one hand, the upper and lower installation positions of the lower pressing forming plate 32 can be finely adjusted, and on the other hand, the lower pressing forming plate 32 can be limited to prevent it from moving upward under excessive pressure, thereby affecting the forming effect of the formed wire 1.

[0086] Further reference Figure 7A and Figure 7BThe forming base 2 is also provided with a positioning block 38. An opening 2123 is provided on one side of the second groove 212 along its extension direction. The positioning block 38 is located on one side of the opening 2123 and is used to abut against the wire to be processed in the second groove 212. The function of the positioning block 38 is to limit the length of the wire to be processed extending out of the second groove 212, making the formed wire 1 more accurate and improving the reliability of the device. Furthermore, the distance between the positioning block 38 and the end face of the second groove 212 is adjustable, thereby adjusting the extension length of the wire to be processed relative to the second groove 212 according to actual needs. For example, the method of adjusting the distance between the positioning block 38 and the end face of the second groove 212 can refer to the method of adjusting the distance between the upper surface of the pressing forming plate 32 and the lower surface of the connecting cover plate 35, which will not be elaborated here.

[0087] Further reference Figure 3 and Figure 12 The lower die holder 34 is provided with a guide member 344, and the forming seat 2 is also provided with a guide groove 23 corresponding to the guide member 344. The guide member 344 can slide in the guide groove 23. For example, the guide member 344 and the guide groove 23 extend in the same direction, both extending vertically. The guide member 344 is a guide rod, and there are two guide rods and two guide grooves 23. When the lower die holder 34 moves vertically, the two guide rods can slide in the two guide grooves 23 respectively to ensure that the lower die holder 34 and the forming seat 2 are positioned corresponding in the vertical direction.

[0088] The following is combined Figures 13 to 18 The longitudinal forming process in the embodiment of the circuit breaker conductive system hard wire forming device in this application is illustrated by way of example. Figure 13 A schematic diagram of the structure of the pressure block 31 is shown. Figure 14 A schematic diagram of the longitudinal forming device 4 and the transverse forming device 5 is shown. Figure 15 A schematic diagram of the structure after longitudinal forming is shown. Figure 16 A schematic diagram of the inclined groove in an embodiment of this utility model is shown. Figure 17 This diagram shows the structure of the longitudinally formed conductor of this invention. Figure 18 It shows Figure 17 Side view of the center guide line extending along the main body 110.

[0089] like Figure 13 As shown, the lower surface of the pressure block 31 is provided with a limiting surface 313, which is used to control the bending direction of the wire to be processed. Specifically, the limiting surface 313 is an inclined surface located at one corner of the lower surface of the pressure block 31. Figure 14As shown, the wire mounting groove 21 also includes a longitudinal forming groove 22, which is connected to the first groove body 211 and is set at an angle. The longitudinal forming groove 22 includes a bottom wall 221 and a side wall 222. Further, the longitudinal forming device 4 includes a longitudinal driving member 41, which is drivenly connected to the longitudinal forming plate 42. The longitudinal driving member 41 drives the longitudinal forming plate 42 along a second direction (e.g., Figure 14 and Figure 15 The longitudinal forming plate 42 moves in the Y direction and contacts the surface of the conductor to be processed, so that the conductor to be processed is bent longitudinally.

[0090] like Figure 15 and Figure 16 As shown, further, the extending directions of the limiting surface 313, the longitudinal forming groove 22, and the longitudinal forming plate 42 are all parallel and extend along the second direction. When the pressure block 31 moves vertically to the end position (i.e., the upper surface of the pressure block 31 abuts against the lower surface of the connecting cover plate 35), the limiting surface 313 forms an inclined groove 44 with the bottom wall 221 and the side wall 222 of the longitudinal forming groove. The inclined groove 44 has a groove opening 441, which is opposite to the side wall 222 of the longitudinal forming groove. The inclined groove 44 is inclined downward relative to the horizontal surface.

[0091] After the bending is completed, a portion of the wire extends from the end of the first groove 211. At this time, the longitudinal forming plate 42 moves along the second direction, pressing the wire extending from the first groove 211 into the longitudinal forming groove 22, thus bending the wire 90° along the second direction. (Reference) Figure 16 and Figure 17 A longitudinal bending portion 130 is formed, and the longitudinal bending portion 130 and the downward bending portion 120 are respectively placed at both ends of the main body portion 110, with the end of the longitudinal bending portion 130 extending out of the longitudinal forming groove 22 to facilitate subsequent lateral bending. (Reference) Figure 18 Since both the inclined groove 44 and the longitudinal forming plate 42 are inclined downwards relative to the horizontal plane, the longitudinally bent portion 130 is not parallel to the horizontal plane after longitudinal bending, but rather forms an angle with the horizontal plane. This angle is as follows: Figure 18 As shown in the figure, β is an acute angle. For example, β can be 15°, 30°, or 45°, etc.

[0092] The longitudinal forming plate 42 and the longitudinal forming groove 22 in this application work together to make the longitudinal forming more precise: on the one hand, when the longitudinal forming plate 42 performs longitudinal bending on the wire to be processed, the longitudinal forming groove 22 mainly plays a limiting role, ensuring the stability and accuracy of the wire to be processed during bending, so that the wire 1 after longitudinal forming can be accurately positioned in front of the transverse forming plate 52 in the moving direction. On the other hand, after the longitudinal forming plate 42 completes the longitudinal bending, it stays at this position, so that the length of the wire 1 after longitudinal forming meets the set requirements, while providing the bending conditions for transverse bending.

[0093] Continue to refer to Figure 14 The lower end of the longitudinal forming plate 42 is connected to a longitudinal guide plate 43. The forming base 2 has a longitudinal guide hole 24, allowing the longitudinal guide plate 43 to slide within it. For example, the longitudinal guide hole 24 is a through hole, penetrating two opposite sides of the forming base 2. The longitudinal guide plate 43 and the longitudinal forming plate 42 are integrally formed. The extending directions of the longitudinal guide plate 43 and the longitudinal guide hole 24 are parallel and both inclined downwards relative to the horizontal plane. Specifically, the extending directions of the longitudinal forming plate 42, the longitudinal guide plate 43, and the longitudinal guide hole 24 all extend along a second direction to ensure that when the longitudinal guide plate 43 moves within the longitudinal guide hole 24, the longitudinal forming plate 42 moves along the second direction. Compared to the prior art using linear guides for guidance, this application utilizes the sliding of the longitudinal guide plate 43 within the longitudinal guide hole 24, resulting in a more compact and smaller overall device structure.

[0094] Continue to refer to Figure 14 and Figure 15 The forming base 2 is also equipped with a baffle 25, which is located in front of the outlet of the longitudinal guide hole 24 and abuts against the end of the longitudinal guide plate 43. The baffle 25 can limit the movement distance of the longitudinal guide plate 43, thereby controlling the movement distance of the longitudinal forming plate 42 along the longitudinal forming groove 22, so that the length of the longitudinally formed wire 1 meets the set requirements. Furthermore, the baffle 25 is equipped with a limiting screw 26, which is threadedly connected to the baffle 25, and the end of the limiting screw 26 abuts against the end of the longitudinal guide plate 43. By adjusting the relative position of the limiting screw 26 and the baffle 25, the movement distance of the longitudinal forming plate 42 along the longitudinal forming groove 22 can be controlled, thereby adjusting the length of the longitudinally formed wire 1.

[0095] The following is combined with Figures 19 to 20 The transverse forming process in the embodiment of the circuit breaker conductive system hard wire forming device in this application is described by way of example. Figure 19 This diagram illustrates the structure of the present invention during transverse forming. Figure 20 A schematic diagram of the transverse forming groove in an embodiment of this utility model is shown. (Reference) Figure 19 and Figure 20 The transverse forming plate 52 is provided with a transverse forming groove 521, which is used to contact the end of the wire to be processed extending out of the longitudinal forming groove 22. Furthermore, the transverse forming groove 521 has a flared opening at one end near the longitudinal forming groove 22, facilitating the smooth entry of the longitudinally formed wire 1 into the transverse forming groove 521. In this embodiment, the extending direction of the transverse forming groove 521 is consistent with the extending direction of the transverse forming plate 52, both along a third direction (as shown in Figures 14 and 15). Figure 19 The transverse forming groove 521 extends in the X direction. In other embodiments, the extension direction of the transverse forming groove 521 can be set according to actual needs.

[0096] Furthermore, as described above, since the longitudinally formed wire 1 can be accurately positioned in front of the transverse forming plate 52 in the moving direction (i.e., the end of the longitudinally formed wire 1 extends out of the longitudinal forming groove 22), when the transverse drive member 51 drives the transverse forming plate 52 to move forward in the third direction, the end of the longitudinally bent portion 130 can smoothly enter the transverse forming groove 521. Afterwards, since the longitudinal forming plate 42 stops at this position after completing the longitudinal bend, the front end face 421 of the longitudinal forming plate can also serve as a limit for the wire to be processed in the subsequent transverse bend. Therefore, as... Figure 19 As shown, when the transverse forming plate 52 continues to move forward along the third direction, the front end face 421 of the longitudinal forming plate and the transverse forming groove 521 work together to bend the end of the longitudinal bending part 130, forming the transverse bending part 140. The wire bending forming process is then complete, and the formed wire 1 has the shape shown in the figure. Figure 1 As shown. By setting the transverse forming groove 521, this application enables the wire to be processed to be more stable and accurate during the transverse forming process.

[0097] Continue to refer to Figure 14The transverse forming device 5 includes a transverse driving member 51, which is drivenly connected to the transverse forming plate 52. The transverse driving member 51 drives the transverse forming plate 52 to move along a third direction, and the transverse forming plate 52 contacts the surface of the wire to be processed, so that the wire to be processed is transversely bent. The transverse forming plate 52 is provided with a transverse guide plate 53, and the forming base 2 is provided with a transverse guide hole 27. The transverse guide plate 53 can slide in the transverse guide hole 27. For example, the transverse guide hole 27 is a through hole, penetrating through the other two opposite sides of the forming base 2. The transverse guide plate 53 and the transverse forming plate 52 are integrally set. The extension direction of the transverse guide plate 53 and the extension direction of the transverse guide hole 27 are parallel and both are inclined downward relative to the horizontal surface. Specifically, the extension directions of the transverse forming plate 52, the transverse guide plate 53, and the transverse guide hole 27 are all parallel and all extend along a third direction to ensure that when the transverse guide plate 53 moves in the transverse guide hole 27, the transverse forming plate 52 moves along a third direction. Compared to the existing technology that uses linear guides for guidance, this application uses a transverse guide plate 53 to slide in the transverse guide hole 27, which makes the entire device structure more compact and smaller in size.

[0098] Continue to refer to Figure 14 The longitudinal forming device 4 includes a longitudinal floating joint 45, which is located between the longitudinal driving member 41 and the longitudinal forming plate 42. The transverse forming device 5 includes a transverse floating joint 54, which is located between the transverse driving member 51 and the transverse forming plate 52. The longitudinal floating joint 45 and the transverse floating joint 54 can compensate for positional errors between the longitudinal driving member 41 and the longitudinal forming plate 42, and between the transverse driving member 51 and the transverse forming plate 52, respectively. They can also absorb mechanical vibrations, thereby protecting the stable operation of the circuit breaker conductive system hard wire forming device. In this embodiment, the downward driving member 33, the longitudinal driving member 41, and the transverse driving member 51 are all cylinders to improve the stability of the operation process. In other embodiments, other driving elements, such as motors, can be selected.

[0099] Figure 21 This diagram illustrates the structure of the hard-wire forming device for the circuit breaker conductive system of this invention from another perspective. (Reference) Figure 2The frame base plate 6 is equipped with four rubber feet 14 to ensure it stands stably on the ground. A vertical mounting plate 9 is installed in the middle of the frame base plate 6. A pressing mold base 34 and a pressing drive component 33 are mounted on one surface of the vertical mounting plate 9. A forming seat 2 is installed directly below the pressing mold base 34, and longitudinal forming devices 4 and transverse forming devices 5, respectively, are fixed to the frame base plate 6 on both sides of the forming seat 2. A two-hand start button and an emergency stop button 8 are installed on the side of the frame base plate 6. Specifically, the two-hand start button includes a first start button 71 and a second start button 72, which are respectively installed on two opposite sides of the frame base plate 6. (Reference) Figure 21 A reinforcing plate 10 is connected to both sides of the vertical mounting plate 9. A pressure regulating valve filter assembly 11, a valve island 12, and an electrical control box 13 are mounted on the other surface of the vertical mounting plate 9 for precise control of the molding process. In this invention, the molding seat 2, the lower pressing molding device 3, the longitudinal molding device 4, and the transverse molding device 5 are all centrally located on the frame base plate 6, making the structure simpler and more compact. Furthermore, the two-hand start buttons are located on both sides of the frame base plate 6 for greater convenience during processing, and their placement on both sides also prevents accidental operation.

[0100] In summary, the circuit breaker conductive system hard wire forming device disclosed in this utility model has a conductor mounting groove 21 consisting of a shallower first groove 211 and a deeper second groove 212 connected by a non-vertical bottom wall. When the pressing forming device 3 presses the conductor to be processed placed in the conductor mounting groove 21, the pressing forming action can be completed directly in the conductor mounting groove 21, without needing to extend the conductor to be processed out of the end of the conductor mounting groove 21. Secondly, the connecting bottom wall of the first groove 211 and the second groove 212 is not vertical. Therefore, the bending angle between the bent section 121 in the pressing bending portion 120 formed by the pressing forming device 3 and the main body 110 will not be 90°, but a small angle bend less than 90°. Then, the longitudinal forming device 4 and the transverse forming device 5 perform longitudinal bending and transverse bending on the conductor to be processed, respectively, to form the longitudinal bending part 130 and the transverse bending part 140, so that the formed conductor 1 can be better adapted to the magnetic ring, thereby improving the quality of the circuit breaker product and the production efficiency of the circuit breaker.
