Description

Technical Field

[0001] This utility model relates to the field of non-standard equipment technology, specifically to a copper plate stamping and riveting device. Background Technology

[0002] A copper plate riveting device is a machine that uses a riveting process to join parts. The riveting process involves applying axial force directly to the workpiece on a press through a punch, causing the material to expand radially to achieve plastic deformation. Then, a riveting head is used to press the plastically deformed parts together to achieve riveting.

[0003] However, due to the relatively soft material of copper plates, copper shavings will be generated on the surface of the copper plates due to damage during the stamping and riveting process. Some of the copper shavings will fall off directly, while some will follow the punch back into the punch's working space, causing copper shavings to accumulate, reducing the punch stroke or causing the punch to jam. The existing way to clean copper shavings is mainly to make the punch detachable and then use an air nozzle to blow them clean. However, this method obviously wastes time and reduces stamping and riveting efficiency. At the same time, frequent disassembly of the punch will also reduce stamping and riveting accuracy. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a copper plate stamping and riveting device, which aims to provide a copper plate stamping and riveting device that can quickly clean copper shavings, so as to improve the stamping and riveting efficiency and ensure the stamping and riveting accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A copper plate stamping and riveting device, the device comprising:

[0007] A base and a guide sleeve, wherein the guide sleeve is nested inside the base;

[0008] An anvil, located on top of the base, is used to support the copper plate to be processed, and a through hole is provided through the anvil. The anvil, the base, and the guide sleeve enclose and form an accommodating space.

[0009] A punching component is mounted on the top of a guide rod via a fixing plate. The guide rod is slidably connected to the guide sleeve. Driven by a driver, the punching component reciprocates within the accommodating space to punch the copper plate to be processed on the anvil when passing through the through hole of the anvil.

[0010] The cutting board is provided with several air inlet channels facing the accommodating space. The fixed plate is provided with a first air outlet channel, and the guide rod is provided with a second air outlet channel communicating with the first air outlet channel. When airflow is introduced through the air inlet channels, the airflow blows away the copper shavings attached to the accommodating space and discharges them through the first air outlet channel and the second air outlet channel.

[0011] According to one aspect of the above technical solution, the cutting board is provided with multiple air intake channels.

[0012] According to one aspect of the above technical solution, the air intake channel includes a first air intake channel and a second air intake channel, and the first air intake channel and the second air intake channel are connected within the anvil.

[0013] According to one aspect of the above technical solution, the first air intake channel is arranged in a circumferential array along the anvil, and the second air intake channel is arranged in a radial array along the anvil.

[0014] According to one aspect of the above technical solution, the cross-sections of the first air intake channel and the second air intake channel are arranged in an L-shape.

[0015] According to one aspect of the above technical solution, the second air intake channel penetrates vertically along the axial direction of the anvil to connect to the first air intake channel, or penetrates obliquely to connect to the first air intake channel.

[0016] According to one aspect of the above technical solution, the fixing plate is provided with a plurality of first air outlet channels, and the guide rod is provided with a plurality of second air outlet channels corresponding to the first air outlet channels.

[0019] According to one aspect of the above technical solution, the device further includes a riveting component facing the through hole of the anvil, for riveting the perforated copper plate on the anvil.

[0020] Compared with the prior art, the copper plate stamping and riveting device shown in this utility model has the following advantages:

[0021] The device shown in this utility model embeds a guide sleeve inside the base, and then sets an anvil on the base to support and fix the copper plate to be processed. The anvil is perforated to form a through hole, so that the anvil, the base, and the guide sleeve enclose a receiving space.

Detailed Implementation

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Example 1

[0032] Please see Figures 1-4 The first embodiment of this utility model provides a copper plate punching and riveting device. The device shown in this embodiment is used to punch and rivet copper plates to be processed, including punching holes in at least two copper plates that are stacked on each other, and then riveting them at the punched positions after punching. In this process, this utility model aims to process the copper shavings generated during punching and riveting to optimize the working environment inside the device, thereby improving the punching and riveting efficiency and ensuring the punching and riveting accuracy.

[0033] The device shown in this embodiment mainly includes: a base 10, a guide sleeve 20, an anvil 30, and a punching component 60.

[0034] The base 10 is hollow and cylindrical in shape. The guide sleeve 20 is nested inside the hollow base 10. The anvil 30 is located on top of the base 10 and is used to create a supporting plane on the base 10 to support and fix the copper plate to be processed. The anvil 30 is also provided with an anvil through hole 31. The anvil 30, the base 10 and the guide sleeve 20 enclose a receiving space 40. The punching component 60 (i.e., the punch) is located on top of a guide rod 70 through a fixing plate 50. The guide rod 70 is slidably connected to the inside of the guide sleeve 20. Driven by a preset driver, the guide rod 70 drives the punching component 60 to reciprocate within the receiving space 40. The punching component 60 can instantly pass through the anvil through hole 31 and retract under the drive of the guide rod 70, punching the plate 90 to be processed fixed on the anvil 30, thereby obtaining a punched plate.

[0035] It should be noted that when the punching component 60 punches the plate 90 to be processed, the plate 90 undergoes plastic deformation due to the creation of through holes. The copper material that makes up the plate 90 to be processed will be partially peeled off, forming copper shavings that fall off. Some of the detached copper shavings will fly directly, while some will follow the punching component 60 back into the receiving space 40. Under the cyclical movement of the punching component 60, they will detach from the receiving space 40. Long-term accumulation will reduce the movement stroke of the guide, causing the punching component 60 to not move in place, and may also get stuck between the guide and the guide sleeve 20, causing the reciprocating movement of the guide to become stuck.

[0036] In this embodiment, in order to quickly clean the copper shavings in the accommodating space 40, several air inlet channels 32 are provided through the anvil 30, and the air inlet channels 32 face into the accommodating space 40. A first air outlet channel 51 is provided through the fixed plate 50, and a second air outlet channel 71 is provided through the guide rod 70. The first air outlet channel 51 and the second air outlet channel 71 are interconnected. When a preset blower is used to introduce airflow into the accommodating space 40 through the air inlet channels 32, the airflow can blow away the copper shavings attached to the inner side wall of the guide sleeve 20, the upper surface of the fixed plate 50, and the lower surface of the anvil 30 in the accommodating space 40. As a result, the copper shavings are discharged from the accommodating space 40 through the first air outlet channel 51 and the second air outlet channel 71 with the airflow, thus ensuring the cleanliness of the accommodating space 40.

[0037] The cutting board 30 is provided with multiple air intake channels 32. Each air intake channel 32 is connected to a blower through a pipe. Each air intake channel 32 includes a first air intake channel 321 and a second air intake channel 322. The first air intake channel 321 and the second air intake channel 322 are connected. Specifically, the first air intake channel 321 extends into the interior of the cutting board 30, and the second air intake channel 322 extends into the interior of the cutting board 30. The first air intake channel 321 and the second air intake channel 322 are connected inside the cutting board 30 to transport airflow.

[0038] More specifically, multiple first air intake channels 321 are arranged in a circumferential array along the anvil 30, while multiple second air intake channels 322 are arranged in a radial array along the anvil 30. That is, the first air intake channels 321 penetrate to the outer circumferential surface of the anvil 30, while the second air intake channels 322 penetrate to the lower surface of the anvil 30. The cross-sections of the first air intake channels 321 and the second air intake channels 322 are arranged in an L-shape, which is convenient to obtain by drilling holes in the anvil 30. In this embodiment, the second air intake channels 322 penetrate vertically along the axial direction of the anvil 30 to connect to the first air intake channels 321. When the airflow passes through the first air intake channels 321 and exits through the second air intake channels 322, the airflow will blow the copper shavings in the accommodating space 40 in a vertical direction.

[0039] In some preferred embodiments, the second air intake channel 322 is inclined through to connect to the first air intake channel 321. Since the second air intake channel 322 has a certain inclination angle and each second air intake channel 322 has a different inclination direction, it is beneficial for multiple airflows to concentrate on blowing a specific area or to disperse blowing multiple areas, thereby quickly blowing away the copper shavings attached to the accommodating space 40.

[0040] In this embodiment, since the copper shavings attached to the accommodating space 40 are mainly cleaned by airflow, it includes not only an air inlet channel 32 but also an air outlet channel, which facilitates the airflow to pass through and carry the copper shavings out.

[0041] The fixed plate 50 is provided with multiple first air outlet channels 51, and at the bottom of the fixed plate 50, the guide rod 70 is provided with second air outlet channels 71 corresponding to the multiple first air outlet channels 51. For example, if there are 3 first air outlet channels 51 on the fixed plate 50, there are also 3 second air outlet channels 71 on the guide rod 70. The first air outlet channels 51 and the second air outlet channels 71 are connected to each other to form a complete air outlet channel. Under the action of pressure difference, the introduced airflow blows the copper shavings in the accommodating space 40 and the copper shavings can be discharged from the air outlet channel with the airflow, thereby reducing the copper shavings attached in the accommodating space 40 and ensuring the cleanliness of the accommodating space 40.

[0042] Specifically, in this guide, one end of the second air outlet channel 71 is connected to the first air outlet channel 51 on the fixed plate 50, and the other end of the second air outlet channel 71 is inclined downward to pass through a preset neck surface 72 in the guide rod 70. The diameter of the neck surface 72 is slightly smaller than that of other parts of the guide, so that a corresponding collection pipe can be arranged in the part other than the neck surface 72 of the guide, thereby collecting copper shavings into the external space.

[0043] In addition, the device also includes a riveting component 80 (i.e., a riveting head), which is positioned above the anvil 30 and directly opposite the anvil through hole 31. Under the drive of the driver, the riveting component 80 performs a riveting process on the punched copper plate on the anvil 30, thereby enabling multiple stacked copper plates to be riveted together at the punching position.

[0044] In the above-mentioned process, when a large amount of copper shavings appear in the accommodating space 40 and affect the reciprocating motion of the guide and punch components, the blower will be activated. Airflow will be introduced into the accommodating space 40 through the first air intake channel 321 and the second air intake channel 322 on the anvil plate 30. The airflow blows away the copper shavings attached to the accommodating space 40 (e.g., the outer surface of the punch component 60, the inner wall of the guide sleeve 20, and the lower surface of the anvil plate 30). Under the action of pressure difference, the copper shavings will be discharged through the first air outlet channel 51 and the second air outlet channel 71 with the airflow, reducing the amount of copper shavings attached to the accommodating space 40, which helps to improve the cleanliness of the accommodating space 40, optimizes the working environment of the accommodating space 40, improves the riveting efficiency, and ensures the riveting accuracy.

[0045] Of course, in some other feasible embodiments, the space 40 can be blown immediately after each riveting process of the plate 90 to be processed, so as to avoid copper shavings from clumping together and increasing the difficulty of cleaning, and to further improve the cleanliness of the space 40.

[0046] In summary, compared with the prior art, the copper plate stamping and riveting device shown in this embodiment has the following advantages:

[0047] The device shown in this embodiment embeds a guide sleeve 20 inside the base 10, and then sets an anvil 30 on the base 10 to support and fix the copper plate to be processed. The anvil 30 is perforated to obtain an anvil through hole 31, so that the anvil 30, the base 10 and the guide sleeve 20 enclose a receiving space 40. The punching component 60 is set on the top of the guide rod 70 through the fixing plate 50. The guide rod 70 is slidably connected in the guide sleeve 20. The guide rod 70 is driven by the driver to drive the punching component 60 to reciprocate so as to punch the plate 90 to be processed when passing through the anvil through hole 31. The copper shavings generated by punching can be introduced into the airflow in the receiving space 40 through the air inlet channel 32 and blown away. The copper shavings will follow the airflow and be discharged from the first air outlet channel 51 on the fixing plate 50 and the second air outlet channel 71 on the guide rod 70, reducing the adhesion of copper shavings in the receiving space 40, which is beneficial to improving the cleanliness of the receiving space 40, optimizing the working environment in the receiving space 40, improving the punching efficiency and ensuring the punching accuracy.
