Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a copper profile processing equipment used in the production of current shunts. Background Technology

[0002] Copper profiles are materials made primarily of copper, possessing specific shapes and dimensions. They exhibit numerous excellent properties and have a wide range of applications. For example, copper connectors are components of current shunt devices. Current shunts utilize two T-shaped copper profiles as connectors, with a bridge plate fixed between them to form the shunt. The production of T-shaped copper profiles for these connectors mainly involves two stages: melting and forming. Electrolytic copper is melted in a cored induction furnace and, after passing chemical analysis, enters the casting process. After casting into ingots, surface quality is inspected. Qualified ingots are sent to the profile workshop, where they are heated in an induction furnace and then extruded, pointed, and drawn. After drawing, they undergo annealing and pickling, followed by straightening and inspection to produce the finished product. Before the formed copper profiles are used to manufacture copper connectors, burrs on the edges need to be removed, and the profiles need to be shaped.

[0003] Therefore, before copper profiles are cut into copper connectors, they generally need to undergo multiple processing steps, including burr removal. Existing burr removal devices typically use a method where the copper profile is fixed and the burr is removed by axially moving a scraper along the burr. Some devices are set up in reverse, where the scraper is fixed and the copper profile is moved along the scraper for removal. One of the characteristics of copper profiles is their high plasticity, which means that when the copper profile is very long, it may deform and bend. Although the overall cross-section still maintains a standard profile, there is a certain degree of axial twisting. This means that the surface of the profile may be damaged during burr removal. Utility Model Content

[0004] To address the shortcomings of the existing technology, this application provides a copper profile processing equipment for the production of current shunts. By setting adaptive and easily adjustable structural components, the scraping efficiency of the copper profile is higher and the scraping effect is better.

[0005] The present invention provides a copper profile processing equipment for the production of current shunts, including a mounting fixture and a cutting disc. The mounting fixture is provided with a mounting ring and a material inlet. The cutting disc includes a blade disc and a scraper. The scraper is fixed in the middle of the blade disc and is also provided with a cutting groove that matches the cross-sectional profile of the copper profile. The cutting disc is movably mounted on the mounting fixture and can rotate relative to the mounting fixture. The blade disc and the mounting ring are concentrically mounted.

[0006] As a further feature of the above solution, the mounting convex ring is provided with a rotating sub-ring and a top claw with helical teeth. The rotating sub-ring rotates circumferentially relative to the mounting convex ring, and the mounting convex ring is also provided with a drive tooth that matches the helical teeth.

[0007] As a further feature of the above scheme, at least three claws are evenly arranged in the circumferential direction relative to the mounting convex ring, and the rotating sub-ring synchronously drives all claws to extend and retract.

[0008] As a further feature of the above solution, an abutment groove is provided at the contact point between the blade disk and the outer side of the front end of the top claw, and the front end of the top claw is configured as a spherical structure, the diameter of which is smaller than the width of the abutment groove.

[0009] As a further provision of the above solution, the mounting fixture includes a fixture frame, the fixture frame includes a base plate on which a mounting protrusion is fixed, the material inlet is located at the middle opening of the mounting protrusion on the base plate, the fixture frame is also provided with guide plates on both sides opposite to the base plate, the fixture frame is provided with a material collecting plate below the mounting protrusion and a baffle plate above the mounting protrusion.

[0010] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0011] 1. Multiple top claws are set to radially extend and lock the blade disc located in the center, radially locking the scraper. By rotating the secondary ring, all top claws can be quickly and synchronously driven to extend and retract, which is convenient for operation.

[0012] 2. The cutting disc is equipped with an abutting groove, and the front end of the top claw matches the abutting groove. During use, the top claw is not locked, which allows for easy adjustment. It can also make slight circumferential movement during turning to adapt to the slight deformation and twisting of the copper profile, thus improving the machining effect.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] like Figure 1-4 The copper profile processing equipment for producing current shunts, as described in this utility model, includes a mounting fixture 1 and a cutting disc 2. The mounting fixture 1 is provided with a mounting protrusion ring 11 and a material inlet 12. The cutting disc 2 includes a blade disc 21 and a scraper 22. The scraper 22 is fixed in the middle of the blade disc 21 and is also provided with a cutting groove 23 that matches the cross-sectional contour of the copper profile. The cutting disc 2 is movably mounted on the mounting fixture 1 and can rotate relative to the mounting fixture 1. The blade disc 21 and the mounting protrusion ring 11 are concentrically mounted.

[0021] As a further provision of the above scheme, the mounting protrusion ring 11 is provided with a rotating sub-ring 13 and a top claw 14 with helical teeth 141. The rotating sub-ring 13 rotates circumferentially relative to the mounting protrusion ring 11, and the mounting protrusion ring 11 is also provided with a drive tooth 142 that matches the helical teeth 141. The rotating sub-ring 13 is axially fixed relative to the mounting protrusion ring 11 and is circumferentially rotatable. It is also provided with a handle for easy pushing and rotating.

[0022] As a further provision of the above scheme, the top claw 14 is provided with at least three evenly spaced grooves on the circumference of the mounting protrusion 11. Figure 1As shown, additional blades can be added according to the size of the blade disc 21, but they need to be evenly distributed in the circumferential direction. The rotating sub-ring 13 synchronously drives all the top claws 14 to extend and retract, and they radially and synchronously abut against the blade disc 21. The outer side of the blade disc 21 and the front end of the top claw 14 are provided with an abutment groove 24. The front end of the top claw 14 is set as a spherical structure 15. The diameter of the spherical structure 15 is smaller than the width of the abutment groove 24. When the top claw 14 is not locked, the spherical structure 15 at the front end of the top claw 14 can be inserted into the abutment groove 24 to form an axial limit on the blade disc 21, but it can rotate in the circumferential direction. Firstly, it is convenient to adjust and then lock. Secondly, it can be processed without locking. When not locked, the blade disc 21 can rotate to a certain extent according to the extension of the copper profile to adapt to the deformation of the copper profile, and improve the surface finish of the copper profile.

[0023] As a further provision of the above solution, the mounting fixture 1 includes a fixture frame 10, the fixture frame 10 includes a base plate 101 on which a mounting protrusion 11 is fixed, the material inlet 12 is located at the middle opening of the mounting protrusion 11 on the base plate 101, the fixture frame 10 is also provided with guide support plates 102 on both sides opposite to the base plate 101, the fixture frame 10 is provided with a material collecting plate 103 below the mounting protrusion 11, and a baffle plate 105 is provided above the mounting protrusion 11.

[0024] The copper profile processing equipment for producing current shunts in this embodiment includes a mounting fixture 1 and a cutting disc 2, such as... Figure 1-2 As shown, in this embodiment, the cutting disc 2 is mounted on the mounting fixture 1 by the cooperation of at least three claws 14. The claws 14 employ a chuck-like structure to achieve synchronous radial extension and retraction. The outer edge of the cutting disc 21 on the cutting disc 2 has an abutment groove 24 opposite to the claws 14. The claws 14 with a certain spherical structure 15 at their front ends extend directly into the abutment groove 24. Figure 3-4As shown, the processing equipment in this embodiment, compared to the prior art, uses a structure where the top claw 14 clamps the blade disc 21. Firstly, this allows for quick disassembly and replacement of the blade disc 21. Secondly, when the long, strip-shaped copper profile exhibits bending or twisting issues as in the prior art, the angle of the scraper 22 fixed on the blade disc 21 can be quickly adjusted by driving the rotating sub-ring 13 to slightly loosen the radial locking of the top claw 14, thus facilitating use. Thirdly, in this embodiment, the end of the blade disc 21 that abuts against the top claw 14 during radial clamping has a spherical structure 15. Although... The front end is flat, but if it is slightly loosened, the radial locking force on the blade disc 21 will be slightly smaller. This allows the blade disc 21 to rotate circumferentially during use, so that the scraper 22 can have a certain degree of rotational adaptive adjustment when removing burrs from the copper profile. This avoids excessive scraping of the copper profile surface and damage to the copper profile contour. In addition, in this embodiment, the clamp frame 10 is provided with a guide support plate 102 and a baffle plate 105 on the side of the copper profile that extends into the scraper 22, which blocks multiple sides of the profile, reduces the flying of copper shavings during scraping, and improves the recycling effect of powder burrs.

[0025] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0026] This specification and accompanying drawings are merely illustrative examples of this application and are intended to cover any and all modifications, variations, combinations, or equivalents within the scope of this application. Clearly, those skilled in the art can make various alterations and modifications to this application without departing from its scope. Therefore, if such modifications and modifications fall within the scope of this application and its equivalents, this application intends to include such modifications and modifications.
