Description

Technical Field

[0001] This utility model relates to a bending forming mold, and more particularly to a bending forming mold for lead wires, belonging to the field of forming mold technology. Background Technology

[0002] In the prior art, such as the invention with application number 202011255404.7, an insulated lead wire bender is disclosed. In use, the insulated lead wire is placed between the moving block and the fixed block. The driving device drives the connecting block to slide in the sliding hole, so that the protrusion of the moving block abuts against the insulated lead wire and inserts into the recess. Under the action of the driving force and the cooperation between the protrusion and the recess, the insulated lead wire is bent and deformed at a certain arc standard.

[0003] The above-mentioned applications still have shortcomings:

[0004] This type of insulated lead wire bender has grooves of fixed size in its protruding and recessed parts, but it can only accommodate lead wires of a specific diameter. For different specifications, the mold needs to be changed, which increases costs and inventory. It is inefficient, and the mold change is time-consuming, which reduces production efficiency, especially when batch operations are carried out. It lacks precision, and the fixed spacing can easily lead to poor lead wire fit, poor bending curvature and dimensional consistency, which cannot meet standardized construction requirements. It may also damage the insulation layer, cause safety hazards, and limit the application scenarios and engineering value.

[0005] To address this issue, a bending forming die for lead wires was designed. Utility Model Content

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a lead wire bending forming mold, which includes a side plate 1. A slider 11 slides on the side plate 1 through a sliding hole. An upper mold 2 is fixed to one side of the slider 11, and the other side of the slider 11 is connected to a driving device. Bolts 4 and sliding rods 14 are symmetrically arranged on both sides of the upper mold 2 diagonally. An upper mold 3 is threaded onto the outer side of the bolts 4, and a connecting hole is provided at the connection between the upper mold 3 and the sliding rod 14. The sliding rod 14 is slidably connected to the connecting hole, and the diameter of the connecting hole is the same as that of the sliding rod 14. The upper mold 1 2 and the upper mold 2 3 are provided with symmetrical inclined grooves 5 at their bottoms. The lower mold 1 6 is fixed on one side of the side plate 1 below the upper mold 1 2. Bolt 2 8 and slide rod 13 are symmetrically arranged on both sides of the diagonal of the lower mold 1 6. The lower mold 2 7 is installed on the outer thread of the bolt 2 8. The lower mold 2 7 and the slide rod 13 are connected with through holes. The bottom of the upper mold 1 2 and the upper mold 2 3 are provided with downward-protruding arc-shaped protrusions. The top of the lower mold 1 6 and the lower mold 2 7 are provided with concave arc-shaped recesses. The two are combined to form a cavity for bending the lead wire.

[0032] The diameter of the through hole matches that of the slide bar 13, and the slide bar 13 is slidably connected to the through hole. The top of the lower mold 16 and the lower mold 27 are provided with mutually symmetrical inclined grooves 29, and a protective component 10 is provided on one side of the lower mold 27.

[0033] Depending on the size of the lead wire, rotate the two sets of bolts 14 diagonally on the upper mold 2 3 with both hands, and rotate bolts 14 so that bolts 14 drive the upper mold 2 3 to slide horizontally along slide bar 2 14 while moving closer to or away from the upper mold 1 2. Adjust the distance between the upper mold 2 3 and the upper mold 1 2 to suit lead wires of different thicknesses. Similarly, adjust the distance between the lower mold 1 6 and the lower mold 2 7 so that the distance between them is the same as the distance between the upper mold 1 2 and the upper mold 2 3. At the same time, the distance between the lower mold 1 6 and the lower mold 2 7 is conducive to the discharge of dust and debris.

[0034] Example 2

[0035] The solution in Example 1 will be further described below with reference to its specific working method.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the protective component 10 further includes a support plate 1001 and an L-shaped limiting strip 1002. The support plate 1001 is symmetrically arranged on the side of the lower mold 7 away from the side plate 1. The top of each support plate 1001 is fixed with an L-shaped limiting strip 1002. The L-shaped limiting strip 1002 leaves a gap between the mounting plate 1003 and one side of the upper and lower molds after installation, preventing the mounting plate 1003 and the transparent protective plate 1005 from being pulled upwards when the mold moves. A limiting plate 1006 is fixed to one side of each L-shaped limiting strip 1002. The mounting plate 1003 is slidably connected to one side of each L-shaped limiting strip 1002. Buffer pads 1004 are evenly arranged on each mounting plate 1003. A transparent protective plate 1005 is fixedly connected to one side of each buffer pad 1004. The transparent protective plate 1005 is a polycarbonate (PC) board with a thickness of 5mm, a light transmittance of ≥92%, and rounded edges to prevent scratches.

[0037] The transparent protective plate 1005 is inserted from top to bottom between the L-shaped limiting strips 1002, so that the transparent protective plate 1005 drives the mounting plate 1003 to be inserted between the L-shaped limiting strips 1002, until the bottom of the mounting plate 1003 contacts the top of the support plate 1001, thus completing the installation of the transparent protective plate 1005. This facilitates the disassembly and cleaning of the transparent protective plate 1005, and also facilitates the maintenance of the lower mold 1 6 and the lower mold 2 7 and the cleaning of the gap between them. The buffer pad 1004 provides cushioning and protection for the transparent protective plate 1005, while leaving a gap between the transparent protective plate 1005 and the lower mold 2 7, which allows splashed debris to be discharged downwards.

[0038] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, a sealing ring is evenly fitted on the end of bolt 4 away from upper mold 2 3, and the sealing ring is rotatably connected to both sides of upper mold 2.

[0039] The sealing rings on both sides, which are slidably connected to the upper mold 2, serve as a limiting force between the upper mold 2 and the bolt 4, so that the upper mold 2 and the bolt 4 remain rotatably connected.

[0040] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a retaining ring is evenly fitted on the end of bolt 2 8 away from lower mold 2 7, and the retaining ring is rotatably connected to both sides of lower mold 1 6.

[0041] The retaining rings on the outside of bolt 28 limit the movement of the lower mold 16 on both sides to prevent the lower mold 16 from dislodging from the outside of bolt 28.

[0042] like Figure 2 As shown, in a preferred embodiment, based on the above method, a scale plate 12 is further installed on both the upper and lower positions of one side of the side plate 1, and the scale plate 12 is slidably connected to the top of the upper mold 3 and the bottom of the lower mold 7 respectively. The scale plate 12 adopts laser etching scale, with each grid representing a 1mm pitch, which matches the bolt pitch.

[0043] The scale plate 12 enables visual positioning for spacing adjustment, allowing operators to precisely control the mold opening and closing dimensions and ensure consistent bending accuracy for lead wires of different diameters.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the buffer pad 1004 is a memory foam buffer layer, and the support plate 1001 is set as an L-shaped plate.

[0045] The memory foam buffer layer effectively absorbs the impact force on the transparent protective plate 1005, preventing accidental displacement caused by vibration when the lead wire bends; the L-shaped support plate 1001 plays a limiting role for the transparent protective plate 1005.

[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, the inclined surfaces of inclined groove 5 and inclined groove 9 are further coated with a protective layer, and the protective layer is a polytetrafluoroethylene coating.

[0047] The PTFE coating significantly reduces the coefficient of friction between the lead wire and the beveled surface of the mold, reduces wear and scratches on the insulation layer during bending, and improves the smoothness of debris sliding, making subsequent cleaning and maintenance easier.

[0048] Example 3

[0049] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0050] Based on the lead wire diameter, rotate the bolts 14 diagonally opposite each other on the upper mold 2 3 with both hands to drive the upper mold 2 3 to slide horizontally along the slide bar 2 14, thereby adjusting the distance between the upper mold 1 2 and the upper mold 2 3 to move closer or further away, adapting to lead wires of different thicknesses; similarly, adjust the distance between the lower mold 2 7 and the lower mold 1 6 to ensure that the upper and lower molds open and close synchronously, and the gap design facilitates the automatic discharge of dust and debris, reducing the frequency of cleaning and maintenance;

[0051] The transparent protective plate 1005 is placed between the L-shaped limiting strips 1002 from top to bottom. Its bottom mounting plate 1003 slides along the L-shaped limiting strips 1002 until it is in contact with the top of the support plate 1001. It can be quickly assembled and disassembled without tools, which facilitates the cleaning of the transparent protective plate 1005 and the lower mold 6 and the lower mold 7. The buffer pad 1004 is evenly distributed between the mounting plate 1003 and the transparent protective plate 1005 to provide elastic cushioning and avoid rigid damage to the transparent protective plate 1005 by the impact force during bending, thereby improving structural stability and operational safety.

[0052] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
