Cutting clamp for copper strip machining

Abstract

The utility model discloses a cutting fixture for copper strip processing, which comprises a tensioning cutting fixture, and the tensioning cutting fixture comprises a tool apron, a cutter, a mounting seat, a support, a pressing seat, a fastener and a catching groove. By arranging the tensioning cutting clamp, when the tool apron is hydraulically driven to cut, the pressing bases make contact with the surface of the copper strip to press the copper strip tightly before the cutter, then the support is stressed to be bent and deformed along with downward movement of the tool apron, the pressing bases are driven to move outwards along the surface of the copper strip, and the pressing bases on the two sides move oppositely to tension the copper strip. Compared with a clamp device in the prior art, the pressing base can press the copper strip downwards to achieve the fixing effect, and the copper strip can be tensioned towards the two sides so that the cutting quality can be improved.

Description

Technical Field

[0001] The utility model relates to the technical field of cutting fixtures, in particular to a cutting fixture used for copper strip processing. Background Art

[0002] Copper strip is a strip material made of pure copper or copper-containing alloys. It has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is therefore widely used in industrial and electrical fields. During the processing, copper strip needs to be cut by a cutting machine into lengths that meet production requirements.

[0003] In the prior art, a clamping seat is installed on the knife seat of the cutting machine. When the knife seat is hydraulically driven to perform a cutting action, the clamping seat will press down on the surface of the copper strip before the cutter to press it firmly and securely, ensuring the normal cutting action. However, the clamping seat can only press down vertically to secure the copper strip, making it difficult to tension the copper strip to both sides to improve the cutting quality. Therefore, the clamping seat lacks functionality. Therefore, we propose a cutting fixture for copper strip processing to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a cutting fixture for copper strip processing to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a cutting fixture for copper strip processing, including a tensioning cutting fixture, the tensioning cutting fixture includes a knife seat, a cutter, a mounting seat, a bracket, a pressure seat, a fastener and a buckle groove, the cutter is installed with a bolt in the assembly groove in the middle of the bottom surface of the knife seat, the mounting seats are symmetrically screwed on the left and right side walls of the knife seat, a bracket is provided at the bottom of the mounting seat, a pressure seat is provided at the bottom of the bracket, the height of the pressure seat is lower than the height of the cutter, a fastener is welded on the side of the mounting seat facing the knife seat, buckle grooves are symmetrically provided on the left and right ends of the bottom surface of the knife seat, and the fasteners are buckled into the inner side of the buckle groove from bottom to top.

[0006] Preferably, the mounting seat, the bracket and the pressure seat are cast as one piece, and the mounting seat, the bracket and the pressure seat are made of spring steel as a whole.

[0007] Preferably, the surface of the bracket is provided with bending portions, the number of the bending portions is not less than 2, and the entire bending portions are equidistantly distributed on the surface of the bracket.

[0008] Preferably, the pressure seat adopts an angular structure.

[0009] Preferably, a rubber gasket is laid on the bottom surface of the pressure seat.

[0010] Preferably, when the fastener and the buckle groove are in a connected state, the mounting holes of the mounting seat and the knife seat are aligned with each other.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model is provided with a tensioning cutting clamp. When the knife seat performs a cutting action under hydraulic drive, the pressure seat will contact the surface of the copper strip before the cutter to press it. Then, as the knife seat moves downward, the bracket will bend and deform under force, thereby driving the pressure seat to move outward along the surface of the copper strip, so that the pressure seats on both sides move toward each other to tension the copper strip. Compared with the clamp device in the prior art, the pressure seat in this case can not only press the copper strip downward to fix it, but also tension the copper strip to both sides to improve the cutting quality.

[0019] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0020] See also Figure 1-5 The utility model provides a cutting fixture for copper strip processing, including a tensioning cutting fixture 1, the tensioning cutting fixture 1 includes a knife seat 11, a cutter 12, a mounting seat 13, a bracket 14, a pressure seat 15, a fastener 16 and a buckle groove 17, the cutter 12 is bolted in the assembly groove in the middle of the bottom surface of the knife seat 11, the mounting seat 13 is symmetrically screwed on the left and right side walls of the knife seat 11, a bracket 14 is provided at the bottom of the mounting seat 13, a pressure seat 15 is provided at the bottom of the bracket 14, the height of the pressure seat 15 is lower than the height of the cutter 12, a fastener 16 is welded on the side of the mounting seat 13 facing the knife seat 11, and buckle grooves 17 are symmetrically provided on the left and right ends of the bottom surface of the knife seat 11, the fastener 16 is buckled into the inner side of the buckle groove 17 from bottom to top, thereby realizing pre-fixation of the mounting seat 13.

[0021] Further explanation: the mounting seat 13, the bracket 14 and the pressure seat 15 are cast as one piece, and the mounting seat 13, the bracket 14 and the pressure seat 15 are made of spring steel as a whole. Spring steel has high strength, hardness and excellent toughness, so that the mounting seat 13, the bracket 14 and the pressure seat 15 have excellent elastic deformation ability to meet the use requirements.

[0022] Further explanation: the surface of the bracket 14 is provided with a bending portion 141, the number of the bending portions 141 is not less than 2, and the overall bending portions 141 are equidistantly distributed on the surface of the bracket 14. The bending portions 141 deform when subjected to force, providing a certain expansion and contraction space for the bracket 14, further improving the elastic deformation ability of the bracket 14, and avoiding the low elastic upper limit of the bracket 14 affecting the normal cutting action of the knife holder 11.

[0023] To further illustrate, the pressure seat 15 adopts an angular structure, which can provide a certain expansion and contraction space for the pressure seat 15, improve the elastic deformation ability of the pressure seat 15, and avoid the elastic upper limit of the pressure seat 15 being too low to affect the normal cutting action of the knife seat 11.

[0024] To further illustrate, a rubber gasket 151 is laid on the bottom surface of the pressure seat 15. The pressure seat 15 can use the rubber gasket 151 to further increase the friction with the copper belt, allowing the pressure seat 15 to more effectively tighten and press the copper belt to both sides.

[0025] To further illustrate, when the fastener 16 and the buckle slot 17 are in a connected state, the mounting holes of the mounting seat 13 and the knife seat 11 are aligned with each other, so that the mounting seat 13 can be pre-fixed, which greatly facilitates the installation operation.

[0026] Here’s how it works:

[0027] First, when assembling the tensioning cutting fixture 1, first fasten the fastener 16 from bottom to top into the inner side of the buckle groove 17 to pre-fix the mounting seat 13. At this time, the mounting holes of the mounting seat 13 and the knife seat 11 are aligned with each other, and the mounting seat 13 and the knife seat 11 can be locked and fixed with screws, making the installation operation convenient.

[0028] Second, when the knife seat 11 performs a cutting action under hydraulic drive, the pressure seat 15 will contact the surface of the copper strip before the cutter 12 to press it, and then as the knife seat 11 moves downward, the bracket 14 will bend and deform under the force, thereby driving the pressure seat 15 to move outward along the surface of the copper strip, so that the pressure seats 15 on both sides move toward each other to tighten the copper strip. Compared with the clamping device in the prior art, the pressure seat 15 in this case can not only press the copper strip downward to fix it, but also tighten the copper strip to both sides to improve the cutting quality.

[0029] Third, by setting a bending portion 141 on the surface of the bracket 14, the bending portion 141 can provide a certain expansion and contraction space for the bracket 14, further improving the elastic deformation ability of the bracket 14, and avoiding the low elastic upper limit of the bracket 14 affecting the normal cutting action of the knife holder 11.

[0030] Fourth, by providing a rubber gasket 151 on the bottom surface of the pressure seat 15, the pressure seat 15 can further increase the friction with the copper strip with the help of the rubber gasket 151, so that the pressure seat 15 can more effectively tighten and press the copper strip to both sides.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
