Description

Technical Field

[0001] This utility model relates to the field of commutator technology, and in particular to a cold heading post-punching dovetail device. Background Technology

[0002] Automobiles require various commutators during use. Commutators are an important component of the armature of DC motors and AC commutator motors, and therefore their prospects are very promising.

[0003] Current commutators require dovetail structures to be machined on high-speed stamping presses, resulting in a small footprint suitable for various production line layouts. However, cold-forged copper busbar structures cannot be machined on traditional high-speed stamping presses.

[0004] Therefore, a dovetail punching device after cold heading is provided to solve the problem that the copper busbar structure after cold heading cannot be processed on a traditional high-speed punch press, and to realize the function of high-speed processing of copper busbar dovetails after cold heading. Utility Model Content

[0005] The purpose of this invention is to provide a dovetail punching device after cold heading, which solves the problem that the copper busbar structure after cold heading cannot be processed on a traditional high-speed punch press.

[0006] To achieve the above objectives, this utility model provides a cold heading post-punch dovetail device, including a base, a lower die, a guide assembly, an upper die mounting plate, an upper die punch, a punch insert, and a feeding assembly. The lower die is mounted on the top of the base, and the two ends of the top of the base are connected to one end of the guide assembly. The upper die mounting plate is connected to the other end of the guide assembly. The upper die punch is fixedly connected to the upper die mounting plate and is located at the bottom of the upper die mounting plate. The feeding assembly is connected to the base and is located on one side of the top of the base.

[0007] The guide assembly includes guide pillars and headless guide sleeves. There are two guide pillars, which are fixedly connected to the base and symmetrically installed on the top of the base. There are two headless guide sleeves, which are fixedly installed in the through holes at both ends of the upper mold mounting plate and cooperate with the guide pillars.

[0008] The feeding assembly includes a feeding channel, a pushing block, and a pushing component. The feeding channel is fixedly connected to the base and located on the top side of the feeding channel. The pushing block is slidably connected to the feeding channel through the pushing component. The pushing component is connected to the pushing block and drives the pushing block to move.

[0009] The pushing component includes a feeding cylinder and a connecting member. The output end of the feeding cylinder is fixedly connected to one end of the connecting member and is located in front of the material channel. The other end of the connecting member is fixedly connected to the pushing block. The connecting member connects the feeding cylinder and the pushing block.

[0010] The cold heading post-punching dovetail device further includes a material-blocking cylinder and a limiting cylinder. The material-blocking cylinder is installed on the side near the material channel; the limiting cylinder is installed on the side near the punching insert.

[0011] This utility model discloses a cold-forging post-punching dovetail device. When processing copper busbar products, the device first loads them using an external vibratory feeder. The product is then linearly fed through the feeding assembly. The blocking cylinder is opened first, and then the feeding assembly pushes the product onto the corner insert. Simultaneously, the limiting cylinder limits the movement of the product. Then, the feeding assembly retracts, and the blocking cylinder is closed. This drives the upper mold mounting plate downwards along the guide assembly for corner punching. The guide block guides and aligns the product, ensuring the accuracy of the dovetail punching. This allows for high-speed processing of copper busbar dovetails even after cold forging. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the cold heading post-punching dovetail device of this utility model. Figure 2 This is a partial structural schematic diagram of the cold heading post-punching dovetail device of this utility model. Figure 3 This is a schematic diagram of the connection structure of the feeding assembly of this utility model.

[0019] This utility model discloses a cold-forging post-punching dovetail device, comprising a base 101, a lower die 102, a guide assembly, an upper die mounting plate 103, an upper die punch 104, a punching insert 105, and a feeding assembly. The guide assembly includes a guide post 106 and a headless guide sleeve 107. The feeding assembly includes a material channel 108, a pusher block 109, and a pushing component. The pushing component includes a feeding cylinder 110 and a connecting piece 111. The cold-forging post-punching dovetail device also includes a blocking cylinder 112 and a limiting cylinder 113. This solution solves the problem that existing cold-forged copper busbar structures cannot be processed on traditional high-speed punch presses; it is understood that the aforementioned solution allows for high-speed processing of copper busbar dovetails even after cold forging.

[0020] In this embodiment, the lower die 102 is mounted on the top of the base 101, and the two ends of the top of the base 101 are connected to one end of the guide assembly. The upper die mounting plate 103 is connected to the other end of the guide assembly. The upper die punch 104 is fixedly connected to the upper die mounting plate 103 and is located at the bottom of the upper die mounting plate 103. The feeding assembly is connected to the base 101 and is located on one side of the top of the base 101. The material blocking cylinder 112 is installed on one side near the material channel 108. The limiting cylinder 113 is installed on one side near the punch insert 105. The base 101 has through holes at both ends for bolt positioning and mounting of the cold heading post-punch dovetail device. The lower die 102 is fixedly mounted at the top center of the base 101. The front side of the lower die 102 has a groove for engaging with the upper die punch 104. A guide assembly is mounted with the lower die 102 as its central axis, and the guide assembly is connected to the upper die mounting plate 103. The same guide assembly vertically guides the punching movement of the upper die mounting plate 103. The upper die punch 104 is fixedly installed at the bottom of the upper die mounting plate 103, so that the guide assembly can also limit the punching trajectory of the upper die punch 104 and prevent the upper die punch 104 from deviating. The front end of the lower die 102 is equipped with the corner insert 105. Now, the stop cylinder 112 is opened, and the copper busbar product is fed to the corner insert 105 through the feeding assembly, and the stop cylinder 113 limits the feeding position of the product to ensure the feeding position. Then the stop cylinder 112 is closed. The material cylinder 112 then drives the upper die mounting plate 103 downwards along the guide assembly for corner punching. A guide block is also installed on the upper die mounting plate 103, located directly in front of the upper die punch 104, to guide and align the product before corner punching, ensuring the accuracy of the dovetail punch. Therefore, when processing copper busbar products using the cold heading and dovetail punching device, the material is first fed by an external vibratory feeder, and the product is linearly fed through the feeding assembly. The material-blocking cylinder 112 is opened, and then the product is pushed onto the corner insert 105 by the feeding assembly. At the same time, the limiting cylinder 113 limits the movement of the product. Then the feeding assembly retracts and the material-blocking cylinder 112 is closed, which drives the upper mold mounting plate 103 to perform corner punching along the guide assembly. The product is guided and aligned by the guide block to ensure the accuracy of the dovetail punching, thus enabling high-speed processing of copper busbar dovetails even after cold heading.

[0021] The guide post 106 comprises two parts, each fixedly connected to the base 101 and symmetrically mounted on the top of the base 101. The headless guide sleeve 107 comprises two parts, each fixedly mounted in the through holes at both ends of the upper mold mounting plate 103 and engaging with the guide post 106. The two guide posts 106 are cylindrical, with their bottom ends engaging with the through holes at both ends of the base 101 and fixedly mounted thereto. The upper mold mounting plate 103 is semi-circular, with through holes at both ends where the headless guide sleeves 107 are fixedly mounted. By having the two headless guide sleeves 107 respectively fitted onto the two guide posts 106 and slidably connected, the movement of the upper mold mounting plate 103 is limited and guided, thereby ensuring the overlap between the upper mold punch 104 and the lower mold 102.

[0022] Secondly, the feed channel 108 is fixedly connected to the base 101 and located on the top side of the feed channel 108; the pusher block 109 is slidably connected to the feed channel 108 through the pusher member; the pusher member is connected to the pusher block 109 and drives the pusher block 109 to move. The feed channel 108 is a straight feed channel 108, and its groove mates with the copper busbar product. One side of the feed channel 108 is provided with a through hole that mates with the pusher block 109 to limit the movement range of the pusher block 109. The rear end of the pusher block 109 has an L-shaped structure. A pusher plate is fixedly installed in the front groove of the pusher block 109. The rear end of the pusher block 109 is connected to the pusher member. The pusher member drives the pusher block 109 to move horizontally along the feed channel 108, pushing the product onto the feed channel 108. The pusher member drives the pusher block 109 to push the product onto the feed channel 108.

[0023] Meanwhile, the output end of the feeding cylinder 110 is fixedly connected to one end of the connecting member 111 and is located in front of the material channel 108; the other end of the connecting member 111 is fixedly connected to the pusher block 109. The connecting member 111 connects the feeding cylinder 110 and the pusher block 109. The feeding cylinder 110 is fixedly installed by a mounting bracket. The output end of the feeding cylinder 110 drives the connecting member 111 to move horizontally and along the through hole of the material channel 108. The movement of the connecting member 111 drives the pusher block 109 to move synchronously. Thus, the feeding cylinder 110 of the pushing member drives the connecting member 111 to move horizontally. The connecting member 111 drives the fixedly connected pusher block 109 to move in the material channel 108, realizing the pusher block 109 to perform linear feeding of the product.

[0024] When using the cold heading post-punching dovetail device of this utility model, when processing copper busbar products through the cold heading post-punching dovetail device, the product is first fed by an external vibratory plate. The product is fed linearly by the feeding component. First, the blocking cylinder 112 is opened, and then the product is pushed onto the corner insert 105 by the feeding component. At the same time, the limiting cylinder 113 limits the movement position of the product. Then the feeding component retracts, and the blocking cylinder 112 is closed. This drives the upper mold mounting plate 103 to punch the corner downwards along the guide component. The product is guided and aligned by the guide block to ensure the accuracy of punching the dovetail, thereby enabling high-speed processing of copper busbar dovetails even after cold heading.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
