Description

Technical Field

[0001] This application belongs to the field of wire processing equipment, and in particular relates to a hook frame forming hook device. Background Technology

[0002] The wire hook is a component used for wiring brushless motors. It mainly consists of copper sheets and a structure where multiple copper sheets are injection-molded together using molding compound, with each sheet insulated from the others. After injection molding, at least one end of the copper sheet needs to be bent to form the wire hook. This bending process, also called a bending process, involves bending the wire hook using external equipment and molds. Currently, multi-pass bending processes are used, requiring multiple sets of molds to complete the process. Furthermore, the copper sheets are arranged in an arc shape, requiring repeated positioning during multiple bending processes. The low precision of mold and product positioning easily leads to defective products where the wire hook is misaligned and collides with adjacent hooks. It can also cause significant differences in the bending angle of the wire hooks within the same batch of products. This not only affects assembly compatibility but also results in uneven stress on the wire hooks, making them prone to breakage. Consequently, product yield remains low, production turnaround time is long, and efficiency is low. Therefore, it is necessary to solve these technical problems. Summary of the Invention

[0003] The purpose of this application is to provide a hook-and-hook forming device for hook frames in one step, so as to solve the technical problem of low production yield of hook frames in the prior art.

[0008] The lower mold assembly includes a lower outer mold and a mold core respectively connected to the base plate, and a separation plate connected to the mold core. The lower outer mold cooperates with the mold core to form an arc-shaped channel for the injection molded body on the hook frame to pass through and an arc-shaped notch for the hook on the hook frame to extend out of the arc-shaped channel. The arc-shaped notch is coaxially connected to the arc-shaped channel. A support cone surface coaxially arranged with the arc-shaped channel is also formed on the lower outer mold. The support cone surface gradually converges in the direction close to the arc-shaped notch. The separation plate cooperates with the lower outer mold to form an inlet and an outlet connected to both ends of the arc-shaped channel.

[0009] The upper mold assembly includes a final bending mold sleeve connected to the top plate and a pre-bending mold connected to the final bending mold sleeve. The final bending mold sleeve has an inner conical surface coaxial with the supporting conical surface and is able to cooperate with the pre-bending mold and the supporting conical surface to form a cavity for bending the hook during the movement of following the top plate.

[0010] Optionally, the pre-bending die is slidably connected to the final bending die sleeve, and the upper die assembly further includes springs at both ends that abut against the pre-bending die and the top plate respectively, wherein the axial direction of the springs and the sliding direction of the pre-bending die are both parallel to the axial direction of the inner conical surface;

[0011] The pre-bending die forms a pre-bent conical surface that can abut against the hook frame before the inner conical surface. The pre-bent conical surface forms a preset slope and can pre-bend the hook to a set angle. The spring has a set deformation range and can connect the pre-bent conical surface to the inner conical surface during the sliding of the pre-bending die relative to the final bending die sleeve.

[0012] Optionally, a first arcuate surface is formed on the lower outer mold to connect the supporting cone surface and the inner wall surface of the arcuate channel, and a second arcuate surface is formed on the pre-bending mold to connect with the pre-bending cone surface;

[0013] The second arc-shaped surface can first abut against the top of the hook in the upright state when it approaches the first arc-shaped surface and guide the top of the hook to the pre-bending cone surface to form a pre-bend of the hook at the set angle. The first arc-shaped surface can abut against and support the pre-bent hook's inner arc surface when the inner cone surface approaches the supporting cone surface.

[0014] Optionally, a protrusion is formed on the pre-bending die with its axial direction parallel to the direction of movement of the pre-bending die, and a guide hole is formed on the lower outer die for the protrusion to fit through and be slidably connected with the protrusion.

[0015] Optionally, the pre-bending die and the top plate form a coaxial countersunk hole, and the two ends of the spring are respectively accommodated in the countersunk hole.

[0016] Optionally, a coaxial inner cavity and a guide hole are formed on the final bending die sleeve, wherein the diameter of the inner cavity is larger than the diameter of the guide hole;

[0017] The pre-bending die is slidably connected to the guide hole, and the pre-bending die also forms a flange slidably connected to the inner cavity.

[0018] Optionally, the upper mold assembly further includes an upper mold mounting plate detachably connected to the top plate, and the final bending mold sleeve is detachably connected to the upper mold mounting plate.

[0019] Optionally, an abutment platform is formed on the mold core, which is coaxial with the arc-shaped channel and is used to abut against the hook frame;

[0020] The distance between the abutment platform and the arc-shaped notch surface is adapted to the height of the injection molded body.

[0021] Optionally, an annular cavity is formed between the abutment platform and the lower outer mold, communicating with the arc-shaped channel.

[0022] Optionally, the arcuate channel is formed to a predetermined length and is capable of accommodating at least two of the hook frames.

[0023] The beneficial effects of the hook frame one-step forming bending hook device provided in this application are as follows: Compared with the prior art, in the hook frame one-step forming bending hook device provided in this application, the arc-shaped channel and arc-shaped notch formed by the cooperation of the lower outer mold and the mold core can realize the precise positioning of the hook frame injection body in the radial direction. Furthermore, the supporting cone surface on the lower outer mold and the inner cone surface on the final bending mold sleeve can form a rigid closed cavity during the mold closing process. Moreover, the geometry of the cavity can directly limit the final bending angle of the hook. In this way, the hook can be forced to bend to the preset angle in a single stamping action, thereby achieving a high degree of consistency in the bending angle of all hooks in the same batch, fundamentally eliminating the angle dispersion defects of traditional processes, and thus significantly improving the product yield, which is far superior to the prior art.

[0034] Please refer to the following: Figures 1 to 4 The present application provides a one-step forming hook device for a wire hook frame. This one-step forming hook device includes a base plate 101, a column 102, a top plate 103, a lower mold assembly, and an upper mold assembly. Wherein:

[0035] The column 102 is vertically connected to the base plate 101; the top plate 103 is slidably connected to the column 102 and can be close to or away from the base plate 101. In this embodiment, the top plate 103 can be driven by a cylinder or motor or other drive mechanism commonly used in the art. The lower mold assembly includes a lower outer mold 104 and a mold core 105 respectively connected to the base plate 101, and a separation plate 106 connected to the mold core 105. The lower outer mold 104 cooperates with the mold core 105 to form an arc-shaped channel 107 through which the injection body 202 on the hook wire frame 201 adapts and passes, and an arc-shaped notch 108 through which the hook 203 on the hook wire frame 201 extends out of the arc-shaped channel 107. The arc-shaped notch 108 is coaxially connected with the arc-shaped channel 107. A support cone surface 109 coaxially arranged with the arc-shaped channel 107 is also formed on the lower outer mold 104. The support cone surface 109 gradually converges in the direction close to the arc-shaped notch 108. The separation plate 106 cooperates with the lower outer mold 104 to form an inlet 110 and an outlet 111 connected to both ends of the arc-shaped channel 107. The upper mold assembly includes a final bending mold sleeve 112 connected to the top plate 103 and a pre-bending mold 113 connected to the final bending mold sleeve 112. The final bending mold sleeve 112 forms an inner conical surface 114 coaxial with the supporting conical surface 109 and can form a cavity for bending the hook 203 by cooperating with the pre-bending mold 113 and the supporting conical surface 109 during the movement following the top plate 103. In this embodiment, the feed port 110 and the discharge port 111 can be used to allow the hook frame 201 to enter or exit the arc-shaped channel 107. That is, the hook frame 201 blank without the hook 203 is put into the feed port 110 and pushed into the arc-shaped channel 107. The upper mold assembly moves down to bend and shape the hook 203 of the hook frame 201 in the arc-shaped channel 107. For each hook frame 201 blank put into the feed port 110, a finished product will be pushed out from the discharge port 111.

[0036] In this embodiment, the separator plate 106 can be detachably connected to the mold core 105. This allows the size of the inlet 110 or outlet 111 to be changed by replacing different separator plates 106, and also facilitates the replacement of easily worn separator plates 106 during long-term use. Furthermore, since the hook 203 is generally made of copper or copper-silver alloy and has a certain degree of elasticity, in specific implementations, the taper of the supporting cone surface 109 can be set slightly smaller than the target bending angle of the hook 203. This way, when the final bending die sleeve 112 moves away from the lower outer die 104, the hook 203 can reduce the friction between itself and the supporting cone surface 109 through a certain degree of rebound. This not only makes it easier for the hook frame 201 to move in the arc-shaped channel 107, but also helps to make the bending angle of the hook 203 more in line with the expected target value.

[0037] According to the structure provided in this embodiment, in the hook frame forming bending device provided in this embodiment, the arc-shaped channel 107 and arc-shaped notch 108 formed by the cooperation of the lower outer mold 104 and the mold core 105 can achieve precise radial positioning of the hook frame 201 injection body 202. Furthermore, the supporting cone surface 109 on the lower outer mold 104 and the inner cone surface 114 on the final bending die sleeve 112 can form a rigidly closed cavity during the mold closing process. Moreover, the geometry of this cavity can directly limit the final bending angle of the hook 203. Thus, the hook 203 can be forcibly bent to a preset angle in a single stamping action. Furthermore, the inner cone surface 114 on the final bending die sleeve 112 is a complete conical structure. Therefore, the hook frame 201... In the arc-shaped channel 107, all subsequent positions except the first hook position can be corrected again by the inner conical surface 114. That is, when the hook frame 201 blank is put into the feed port 110 and pushed to the first position in the arc-shaped channel 107, after the upper die assembly moves down to bend the hook 203, the hook frame 201 with the bent hook 203 is between this position and the discharge port 111. Each time the upper die assembly moves down to bend the new hook frame 201 blank, the hook 203 of the hook frame 201 with the bent hook 203 is corrected once. In this way, the bending angle of all hooks 203 in the same batch can be highly consistent, fundamentally eliminating the angle dispersion defects of traditional processes, thereby significantly improving the product yield, which is far superior to the existing technology.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The pre-bending die 113 is slidably connected to the final bending die sleeve 112. The upper die assembly also includes a spring 115 with its two ends abutting against the pre-bending die 113 and the top plate 103 respectively. The axial direction of the spring 115 and the sliding direction of the pre-bending die 113 are both parallel to the axial direction of the inner conical surface 114. A pre-bending conical surface 116 is formed on the pre-bending die 113, which can abut against the hook frame 201 before the inner conical surface 114. The pre-bending conical surface 116 forms a preset slope and can pre-bend the hook 203 to a set angle. The spring 115 has a set deformation range and can connect the pre-bending conical surface 116 to the inner conical surface 114 during the sliding of the pre-bending die 113 relative to the final bending die sleeve 112.

[0039] According to the structure provided in this embodiment, the pre-bent conical surface 116 can abut against the hook 203 before the inner conical surface 114. When the abutment force between the hook 203 and the pre-bent conical surface 116 overcomes the elastic force of the spring 115, the pre-bending die 113 can slide relative to the final bending die sleeve 112 and pre-bend the hook 203 to a set angle. When the pre-bent conical surface 116 is connected to the inner conical surface 114, the inner conical surface 114 can quickly bend the hook 203 to the target angle. This not only improves the forming efficiency of the hook 203, but also further improves the bending forming yield of the hook 203.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The lower outer mold 104 also forms a first arcuate surface 117 for connecting the supporting cone surface 109 and the inner wall of the arcuate channel 107. The pre-bending mold 113 forms a second arcuate surface 118 that connects to the pre-bending cone surface 116. The second arcuate surface 118 can first abut against the top of the upright hook 203 and guide the top to the pre-bending cone surface 116 to pre-bend the hook 203 at a set angle when it approaches the first arcuate surface 117. The first arcuate surface 117 can abut against and support the inner arc surface of the pre-bent hook 203 when the inner cone surface 114 approaches the supporting cone surface 109. According to the above structure provided in this embodiment, the bending position of the hook 203 can form a smooth transition fillet, ensuring that the inner hook arc of the hook 203 is within the set range value, which is beneficial to further improve the forming yield of the hook frame 201.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 A protrusion 119 is formed on the pre-bending die 113 with its axial direction parallel to the moving direction of the pre-bending die 113. A guide hole 120 is formed on the lower outer die 104 for the protrusion 119 to fit through and to slide with the protrusion 119. According to the structure provided in this embodiment, the protrusion 119, which can extend into and slide with the guide hole 120, can not only provide a moving guide for the movement of the pre-bending die 113, but also bear a certain shear bending moment during the bending process of the final bending die sleeve 112 on the hook 203. This can reduce the bending force on the column 102 and make the overall structure more stable, thereby helping to further improve the forming yield of the hook frame 201.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 A coaxial countersunk hole 121 is formed on the pre-bending die 113 and the top plate 103, and both ends of the spring 115 are respectively accommodated in the countersunk hole 121. According to the structure provided in this embodiment, the countersunk hole 121 formed on the pre-bending die 113 and the top plate 103 can keep the spring 115 in good positional stability, which can make the pre-bending die 113 slide more stably relative to the final bending die sleeve 112, thereby also helping to further improve the forming yield of the hook frame 201.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The final bending die sleeve 112 forms a coaxial inner cavity 122 and a guide hole 123, with the diameter of the inner cavity 122 being larger than the diameter of the guide hole 123. The pre-bending die 113 is slidably connected to the guide hole 123, and the pre-bending die 113 also forms a flange 124 slidably connected to the inner cavity 122. According to the structure provided in this embodiment, the flange 124 formed on the pre-bending die 113 can not only improve the sliding stability of the pre-bending die 113 relative to the final bending die sleeve 112, but also prevent the pre-bending die 113 and the final bending die sleeve 112 from separating from each other, which is also conducive to further improving the forming yield of the hook frame 201.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The upper mold assembly also includes an upper mold mounting plate 125 detachably connected to the top plate 103, and a final bending die sleeve 112 detachably connected to the upper mold mounting plate 125. According to the structure provided in this embodiment, the detachable connection between the upper mold mounting plate 125, the final bending die sleeve 112, and the top plate 103 not only facilitates the installation of the final bending die sleeve 112 but also makes subsequent maintenance and replacement more convenient, thus further improving the forming yield of the hook frame 201.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 An abutment platform 126, coaxial with the arc-shaped channel 107 and used to abut against the hook frame 201, is formed on the mold core 105. The distance between the abutment platform 126 and the opening of the arc-shaped notch 108 is adapted to the height of the injection molded body 202. According to the structure provided in this embodiment, the abutment platform 126 formed on the mold core 105 can further define the position of the injection molded body 202, so that the hook 203 connected to the injection molded body 202 can be better adapted to the position of the support cone surface 109, ensuring that the length of the hook 203 is within the set value range after bending, thereby helping to further improve the molding yield of the hook frame 201.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 An annular cavity 127 is formed between the abutment platform 126 and the lower outer mold 104, communicating with the arc-shaped channel 107. According to the structure provided in this embodiment, the annular cavity 127 formed between the abutment platform 126 and the lower outer mold 104 can reduce the friction between the hook frame 201 and the lower outer mold 104 in this embodiment, allowing it to move more smoothly within the arc-shaped channel 107, which is also beneficial to further improve the molding yield of the hook frame 201.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The arc-shaped channel 107 is formed to a predetermined length and can accommodate at least two hook frames 201. According to the structure provided in this embodiment, multiple hook frames 201 can be simultaneously installed in the arc-shaped channel 107. Thus, a hook frame 201 entering the arc-shaped channel 107 later can push the hook frame 201 that entered the arc-shaped channel 107 earlier to move and exit the arc-shaped channel 107 from the discharge port 111. Furthermore, the hooks 203 already formed to the target angle on the hook frame 201 can be repeatedly corrected by the final bending die sleeve 112 during movement within the arc-shaped channel 107, which also helps to further improve the forming yield of the hook frame 201.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
