Description

Technical Field

[0001] This invention relates to the field of crimping mold technology, specifically to a cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles. Background Technology

[0002] The ring terminal crimping mold for high-voltage cables in new energy vehicles is a precision tooling specifically designed for cold-pressing connections between large-diameter high-voltage cables and O-type / ring terminals. It consists of upper and lower hard alloy modules that fit together. The cavity is mostly hexagonal or polygonal with rounded transitions. With the help of a servo / hydraulic press, several tons to tens of tons of pressure are applied, causing the ring terminal metal to plastically deform and tightly wrap around the conductor core, forming a low-resistance, high-tensile-strength, airtight cold welded connection. It is suitable for high-current and strong vibration conditions in high-voltage circuits such as power batteries and motors.

[0003] However, existing technology uses a rigid positioning reference for the head of the annular end cap (i.e., using the head of the annular end cap as an axial limit), and requires operators to manually overcome the curvature of the cable for forced alignment during operation. Therefore, when a curved cable is fed into the mold, the worker needs to forcefully press the end cap head against the limiting workpiece and forcibly straighten the tilted annular end cap head to meet the positioning conditions. This results in the pre-crimping terminal and the wire tube being in an unnatural state of stress coupling. As the mold presses down, the upper mold forcibly flattens the tilted end cap. During this process, the end cap head and the limiting workpiece experience hard friction and plating peeling under the huge crimping force, leading to plating peeling, exposure and oxidation of the copper substrate, and a significant increase in contact resistance. Under high current, this can easily cause abnormal heating or even ablation, posing certain safety hazards. Summary of the Invention

[0004] (a) Technical problems to be solved: To address the shortcomings of existing technologies, this invention provides a cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles, which solves the problem mentioned in the background technology of rigid positioning reference and reliance on manual overcoming of cable curvature, resulting in hard friction and plating peeling at the end head.

[0005] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles, comprising: A crimping mechanism for crimping annular ends; An adjustment mechanism is set on the other side of the high-voltage line entering the crimping mechanism. It includes a damping rotating plate with a rotating shaft set at its bottom. The adjustment mechanism is used to position the head of the annular end of the crimping mechanism by using the fixed damping rotating plate. During the crimping process, the damping rotating plate is released from its fixed position and rotated under the action of the deformed annular end, preventing the annular end from coming into close contact with the damping rotating plate and causing wear. A limiting plate, disposed between the pressing mechanism and the damping rotating plate, includes a plate body with a straight slot in the middle for the insertion of a high-voltage line. The limiting plate is used to position the high-voltage line outside the high-voltage line and guide the head of the annular end to move vertically using the side wall of the straight slot. In conjunction with the adjusting mechanism, the vertical deformation of the head of the annular end is completely converted into the rotational force of the damping rotating plate.

The first toothed plate is fixedly connected to the top of the V-shaped plate, and has several locking teeth on the side near the mold body; The contact side is fixedly connected to the fixing frame and located outside the connecting rod. It is inclined on one side wall away from the mold body to fit the side wall of the connecting rod after rotation. An alarm is fixedly connected to the end of the contact side away from the connecting rod, and is used to issue an alarm to remind the operator that the damping plate has rotated too much due to the high-voltage line being inserted too deeply. An alarm button is located at one end of the alarm near the connecting rod and inserted into the inside of the contact side, for being pressed by the rotating connecting rod to trigger the alarm.

[0008] Preferably, the fixing frame is connected to the damping rotating plate for damping rotation.

[0009] Preferably, the damping plate has a sliding groove for the movable plate to slide vertically.

[0010] Preferably, the adjustment mechanism further includes: An identification block is disposed on the side wall of the damping rotating plate and located in the middle of the sliding groove, and is integrally formed with the damping rotating plate; The marking line is applied to the middle of the marking line, and when aligned with the marking block, the movable plate is located in the middle of the sliding groove.

[0011] Preferably, the damping plate, the movable plate, the connecting rod, and the roller are all made of lightweight, rigid materials.

[0012] Preferably, the limiting plate further includes: The driven plate is fixedly connected to the output end of the telescopic rod and moves synchronously with the output end of the telescopic rod. The driven plate extends from the inside of the mold body to the outside of the mold body. The second toothed plate is fixedly connected to the top of the driven plate at the end away from the telescopic rod, and has several locking teeth on the side away from the mold body; The contact ring is fixedly connected to the side wall of the straight groove of the plate body. The side away from the plate body is set with a rounded corner to avoid the head of the annular end from contacting the contact ring and causing scratches. A camera is fixedly connected to the side of the plate near the damping plate and located above the contact ring, for monitoring the condition of the lower annular end. The display is fixedly connected to the top of the base and located on the side of the mold body where the high-voltage line is inserted. The display is connected to the camera via a wire and is used to provide the operator with specific information about the high-voltage line insertion and crimping process.

[0013] Preferably, the contact ring is made of a material with a low coefficient of friction.

[0014] Preferably, it further includes: A transmission gear is rotatably connected to the fixed frame and is located between the first toothed plate and the second toothed plate, meshing with both the first toothed plate and the second toothed plate simultaneously. It is used to drive the first toothed plate to move in the opposite direction by moving the second toothed plate. A dustproof frame is fixedly connected to the side wall of the mold body near the transmission gear, and shields the first tooth plate, the second tooth plate and the transmission gear to prevent external dust and objects from affecting the transmission between the first tooth plate, the second tooth plate and the transmission gear; The controller is fixedly connected to the top of the mold body and is connected to the telescopic rod, the alarm and the display via wires. It is used to control the operation of the telescopic rod, the alarm and the display and to supply power.

[0015] (III) Beneficial Effects: The cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles provided by this invention has the following beneficial effects: 1. This is a cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles. Before crimping, the ring end head is axially positioned by a damping rotating plate. During the crimping process, the fixed constraint is automatically released and the end head rotates synchronously with the deformation. This transforms the strong extrusion and hard friction between the end head and the positioning part into smooth rotation, avoiding scratching and peeling of the end head plating and exposure and oxidation of the copper conductor. This reduces contact resistance, eliminates the safety hazards of heat generation and ablation under high current conditions, and improves the long-term reliability of high-voltage connections.

[0016] 2. This is a cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles. By using a limiting plate, the ring end is constrained to deform and displace only in the vertical direction, avoiding horizontal offset and lateral tilt that would cause wear and scratches on various parts of the ring end. The deformation and displacement energy of the end is converted into the rotational force of the damping plate, further enhancing the rotational effect of the damping plate. This avoids hard impact, jamming, and poor crimping caused by offset, ensuring uniform crimping dimensions and consistent stress, and improving the connection strength and conductivity stability between the end and the cable.

[0017] 3. This is a cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles. The high-voltage line is radially centered and vertically guided by a limiting plate. The adjustment mechanism provides an axial positioning reference with a damping rotating plate, directly positioning the end of the inserted high-voltage line, reducing the difficulty of operation and improving the consistency of crimping.

[0018] 4. This cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles automatically unlocks and resets by using a telescopic rod to drive the toothed plate and gears. With the help of a camera and display, the end position status is displayed in real time. When the insertion is too deep or the rotation is too large, an alarm is automatically triggered to remind you. This can significantly reduce the error of manual alignment and the risk of operation, improve crimping accuracy, production efficiency and equipment safety, and meet the needs of mass production and high consistency of new energy high-voltage lines.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 refer to Figures 1 to 10 A preferred embodiment of the present invention, a cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles, will be described in detail below: A cable ring end crimping mold for manufacturing high-voltage lines for new energy vehicles, comprising: A crimping mechanism is used to crimp ring-shaped terminals. This crimping mechanism is existing technology and typically uses a hexagonal crimping method to mechanically crimp the ring-shaped terminal to the high-voltage cable, ensuring that the resulting electrical connection has low resistance and high tensile strength.

[0023] An adjustment mechanism is set on the other side of the high-voltage line entering the crimping mechanism. It includes a damping rotating plate 31 with a rotating shaft at its bottom. The adjustment mechanism is used to position the annular end head entering the crimping mechanism using the fixed damping rotating plate 31. During the crimping process, the damping rotating plate 31 is released from its fixed position and rotated under the action of the deformed annular end head. This releases the hard contact force between the annular end head and the positioning structure, converting the original hard friction into the rotational motion of the damping rotating plate 31, and preventing the annular end head from coming into close contact with the damping rotating plate 31 and causing wear. A limiting plate, positioned between the pressing mechanism and the damping rotating plate 31, includes a plate body 42 with a straight slot in the middle for the insertion of the high-voltage line. The limiting plate is used to position the high-voltage line outside the high-voltage line and guide the head of the annular end to move vertically using the side wall of the straight slot. This ensures that the head of the annular end moves in a predetermined direction during deformation and directly pushes the damping rotating plate 31 to rotate, preventing the head of the annular end from moving to other directions and causing the damping rotating plate 31 to be unable to rotate along the axis and produce hard contact. In conjunction with the adjustment mechanism, the vertical deformation of the head of the annular end is completely converted into the rotational force of the damping rotating plate 31.

[0024] The crimping mechanism includes: The base 10 provides stable support for the entire mold.

[0025] The mold body 20 is fixedly connected to the top of the base 10; The upper pressing block 21 is slidably connected to the inside of the mold body 20, and has an upper pressing end at the bottom. The lower pressing block 22 is slidably connected inside the mold body 20 and located below the upper pressing block 21. The top is provided with a lower pressing end aligned with the upper pressing block 21. When the upper pressing end and the lower pressing end are combined, a pressing cavity is formed, which presses the original annular end into a hexagonal end. It can also be adjusted to a quadrilateral pressing according to existing technology, pressing the annular end into a quadrilateral end.

[0026] The telescopic rod 23 is vertically set and fixedly connected to the mold body 20. Its output end is fixedly connected to the top of the upper pressing block 21 and is used to drive the upper pressing block 21 to move in the vertical direction to press the annular joint.

[0027] The regulating mechanism also includes: The fixing bracket 30 is fixedly connected to the top of the base 10 and is located on the other side of the mold body 20 where the high voltage line enters, so that the inserted high voltage line and the annular end head on the outer side of its end can pass through the mold body 20 and contact the damping rotating plate 31.

[0028] The movable plate 32 is slidably connected to the middle of the fixed frame 30 and aligned with the upper and lower pressing ends of the upper pressing block 21 and the lower pressing block 22. When the annular end is pressed and deformed or displaced, the movable plate 32 can move with the head of the annular end (the displacement of the annular end is limited to the vertical direction by the limiting plate, which facilitates the sliding of the movable plate 32), thereby reducing the friction when in contact with the annular end.

[0029] Two connecting rods 33 are spaced apart from each other, and their bottoms are fixedly connected to the top of the damping rotating plate 31 for easy connection of the roller 34.

[0030] Roller 34 is positioned between two connecting rods 33 and rotatably connected to them. V-shaped plate 35 has a diameter larger than the width of the two connecting rods 33, allowing it to contact the V-shaped plate 35 before the connecting rods 33. Rolling during the downward stroke of the V-shaped plate 35 reduces resistance and prevents jamming of the damping plate 31, thus facilitating the V-shaped plate 35 to return the damping plate 31 to a vertical position (e.g., ...). Figure 3 As shown, the entire mold is in standby mode at this time.

[0031] V-shaped plate 35, which is set as an inverted "V" shape, is located on the top outer side of roller 34 and its inner wall is spaced from the connecting rod 33. It is used to descend with its inner inclined surface to contact roller 34 and guide V-shaped plate 35 back to the vertical position. The first toothed plate 351 is fixedly connected to the top of the V-shaped plate 35, driving the V-shaped plate 35 to move synchronously with itself, and several locking teeth are provided on the side near the mold body 20.

[0032] The contact side 36 is fixedly connected to the fixing frame 30 and located outside the connecting rod 33. The side wall away from the mold body 20 is inclined to fit against the side wall of the rotating connecting rod 33 to increase the contact area with the connecting rod 33 and avoid collision. It also limits the maximum rotation angle of the damping plate 31, prevents the damping plate 31 from rotating excessively, and provides a mounting base for the alarm 37.

[0033] The alarm 37 is fixedly connected to the end of the contact side 36 away from the connecting rod 33. It is used to issue an alarm to remind the operator that the damping plate 31 has rotated too much due to the high voltage line being inserted too deeply, so as to avoid continuing the crimping work and causing greater wear to the ring end. At this time, the insertion of the high voltage line end too deeply may also cause the ring end to shift and not fully enter the crimping range, resulting in crimping defects.

[0034] The alarm button 371 is the trigger element of the alarm 37. It is located at one end of the alarm 37 near the connecting rod 33 and inserted into the inside of the contact side 36. It is used to trigger the alarm 37 by being pressed by the rotating connecting rod 33, ensuring that the alarm is activated only when the damping plate 31 rotates too much, thus avoiding false alarms that may interfere with normal production.

[0035] The fixed frame 30 is connected to the damping rotating plate 31 in a damping rotational connection, so that the damping rotating plate 31 maintains its current position when no external force is applied, and prevents the damping rotating plate 31 from swinging freely due to gravity or slight vibration.

[0036] The damping plate 31 has a sliding groove for the movable plate 32 to slide vertically, ensuring deformation under the action of the limiting plate. The annular end of the displacement accurately triggers the movable plate 32 to follow the movement, further avoiding hard contact between the movable plate 32 and the annular end, which would cause wear.

[0037] The regulating mechanism also includes: The marker block 311 is set on the side wall of the damping rotating plate 31 and located in the middle of the sliding groove. It is integrally formed with the damping rotating plate 31 and provides an adjustment reference for the movable plate 32 when it shifts due to long-term use. It is also used to help the operator judge whether the movable plate 32 is in the center position.

[0038] Marking line 321 is applied to the middle of the marking line 321. When aligned with marking block 311, the movable plate 32 is located in the middle of the sliding groove, which reduces the alignment difficulty for operators and improves positioning accuracy.

[0039] The damping plate 31, movable plate 32, connecting rod 33 and roller 34 are all made of lightweight rigid materials. Specifically, plastic materials such as PEEK (polyether ether ketone) can be selected, as well as aluminum alloy, titanium alloy, or carbon fiber composite materials. This makes the rotation response of the damping plate 31 more sensitive and reduces the additional pressure exerted by its own weight on the annular end.

[0040] The following is the complete working process and working principle of the above embodiments: The operator inserts the ring-shaped high-voltage cable between the upper crimping block 21 and the lower crimping block 22. The head of the ring-shaped cable first contacts the damping rotating plate 31, which is in a fixed state, to achieve axial positioning. At the same time, the movable plate 32 automatically adjusts its position within the sliding groove of the damping rotating plate 31 according to the position of the cable head. The operator judges whether the insertion depth is appropriate by checking the alignment of the marker block 311 and the marker line 321. Subsequently, the operator activates the telescopic rod 23. Driven by the limit plate and the transmission gear 50, the V-shaped plate 35 rises and no longer contacts the roller 34, releasing the fixed constraint on the damping rotating plate 31. As the upper pressing block 21 continues to press down for pressing, the annular end head pushes the movable plate 32 to slide vertically within the sliding groove of the damping rotating plate 31, causing the damping rotating plate 31 to rotate around its bottom axis. This transforms the hard friction that might have occurred between the annular end head and the damping rotating plate 31 into the rotational motion of the damping rotating plate 31, preventing the end head from coming into close contact with the damping rotating plate 31 and causing the plating to peel off. Simultaneously, if the damping rotating plate 31 rotates too much, the inclined sidewall of the contact side 36 will adhere to the sidewall of the connecting rod 33, limiting the continued rotation of the damping rotating plate 31 and preventing structural interference due to excessive rotation. During this process, the connecting rod 33 will press the alarm button 371, triggering the alarm 37 to sound an alarm and remind the operator to stop pressing. After crimping is completed, the telescopic rod 23 drives the upper crimping block 21 to reset, and the driven plate 40 rises synchronously. Through the transmission gear 50, it drives the V-shaped plate 35 to move in the opposite direction. The inclined surface of the inner wall of the V-shaped plate 35 contacts the roller 34 and guides the connecting rod 33 to retract inward and reset. Under the damping action of the damping rotation connection, the damping rotating plate 31 returns to its initial fixed state (e.g., Figure 5 (As shown), to prepare for the next crimping.

[0041] Example 2 refer to Figures 1 to 6 , Figure 11 The limit plate also includes: The driven plate 40 is fixedly connected to the output end of the telescopic rod 23 and moves synchronously with the output end of the telescopic rod 23 to realize the linkage of pressing, positioning and auxiliary adjustment. The driven plate 40 extends from the inside of the mold body 20 to the outside of the mold body 20. The second toothed plate 41 is fixedly connected to the top of the driven plate 40 at the end away from the telescopic rod 23, and has several locking teeth on the side away from the mold body 20. The contact ring 43 is fixedly connected to the side wall of the straight groove of the plate 42. The side away from the plate 42 is set with a rounded corner to avoid the head of the annular end from contacting the contact ring 43 and causing scratches, and also to facilitate the vertical displacement of the annular end.

[0042] Camera 44 is fixedly connected to the side of plate 42 near damping plate 31 and located above contact ring 43. It collects real-time position images of the annular end head to monitor the condition of the annular end head below and provides visual assistance to operators.

[0043] The display 45 is fixedly connected to the top of the base 10 and is located on the side of the mold body 20 where the high-voltage line is inserted. The display 45 is connected to the camera 44 via a wire and is used to provide the operator with specific information about the high-voltage line insertion and crimping process.

[0044] The contact ring 43 is made of a low coefficient of friction material, specifically ceramic material, which ensures hardness while having a low coefficient of friction, thereby further reducing the sliding resistance between the ring end head and the limiting plate, reducing the risk of wear on the plating and sidewalls, and extending the service life of the mold.

[0045] Also includes: The transmission gear 50 is rotatably connected to the fixed frame 30 and is located between the first toothed plate 351 and the second toothed plate 41, meshing with both. It is used to drive the first toothed plate 351 to move in the opposite direction via the movement of the second toothed plate 41, achieving reverse linkage between the V-shaped plate 35 and the plate body 42. This causes the V-shaped plate 35 to rise during the pressing process, contacting the constraint on the roller 34, and then descend after pressing, repositioning the roller 34 to a vertical position (e.g., ...). Figure 9 (As shown).

[0046] The dustproof frame 60 is fixedly connected to the side wall of the mold body 20 near the transmission gear 50, and shields the first tooth plate 351, the second tooth plate 41 and the transmission gear 50 to prevent external dust and objects from affecting the transmission between the first tooth plate 351, the second tooth plate 41 and the transmission gear 50, thereby extending their service life and improving the stability of operation.

[0047] The controller 70 is fixedly connected to the top of the mold body 20 and is connected to the telescopic rod 23, the alarm 37 and the display 45 via wires. It is used to regulate the operation of the telescopic rod 23, the alarm 37 and the display 45 and to supply power. Specifically, it can coordinate the pressing action, alarm triggering and display feedback, thereby realizing automated control.

[0048] The following is the complete working process and working principle of the above embodiments: The operator passes the high-voltage wire with a ring-shaped end through the straight slot of the limiting plate 42. The side wall of the straight slot and the low-friction rounded corner contact ring 43 forcibly constrain the ring-shaped end to move only in the vertical direction, precisely limiting its horizontal and lateral displacement. Guided and positioned by the low-friction rounded corner contact ring 43 to avoid rubbing, the end head reaches the damping rotating plate 31 to complete axial positioning. The camera 44 collects the end position in real time and transmits it to the display 45 for the operator to confirm. When the telescopic rod 23 is activated to drive the upper pressing block 21 to press down, the driven plate 40 moves down synchronously with the telescopic rod 23 and drives the transmission gear 50 to rotate through the second toothed plate 41, thereby driving the first toothed plate 351 and the inverted V-shaped plate 35 to rise, releasing the fixed constraint on the roller 34 and the damping rotating plate 31. After the pressing is completed, the telescopic rod 23 is reset, the driven plate 40 moves up and drives the V-shaped plate 35 to descend via the transmission gear 50, and the roller 34 and the damping rotating plate 31 are reset to the initial positioning state by the inclined surface. The dustproof frame 60 protects the transmission components, and the controller 70 coordinates the pressing, alarm, display and power supply. The entire process combines limit guidance, synchronous transmission, visual monitoring, overload alarm and damping anti-wear structure.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
