Technical Field

[0001] The invention relates to the field of copper wire component processing, and in particular to a copper wire component cutting tool with a long service life. Background Art

[0002] The existing automobile starter armature component flat copper wire cutting tool consists of an upper cutting knife die and a lower cutting knife die. A cutting station is formed between the upper cutting knife die and the lower cutting knife die. The flat copper wire passes through the cutting station. The upper cutting knife die is pressed down by a moving device, and the flat copper wire is cut in cooperation with the lower cutting knife die.

[0003] In the process of cutting the flat copper wire, since the cutting of the flat copper wire requires square cutting of the flat copper wire, the smaller the width of the flat copper wire waste generated in the process of cutting the flat copper wire, the better. In the actual cutting process, since the width of the flat copper wire waste is small, the reaction force generated when the upper cutting die and the lower cutting die contact with the flat copper wire for extrusion cutting is large, and the actual cutting surface of the upper cutting die and the lower cutting die is small. When affected by the reaction force, the blades of the upper cutting die and the lower cutting die are under great burden, so they are prone to breakage during long-term use, and their service life is not high. Summary of the invention

[0004] The present application provides a high-life copper wire element cutting tool, which can solve the technical problem of short service life of the upper cutting knife die and the lower cutting knife die in the prior art.

[0005] The embodiment of the present application provides a long-life copper wire element cutting tool, which includes:

[0006] An upper cutting tool, the upper cutting tool is used to connect the power device, the upper cutting tool is provided with a cutting blade, and auxiliary forming blocks are connected to both sides of the cutting blade in the length direction, the thickness of the two auxiliary forming blocks is not less than the thickness of the cutting blade, and the cross-sectional size S of the auxiliary forming block gradually increases from the end close to the cutting blade toward the end away from the cutting blade;

[0007] And, a lower cutting tool, the lower cutting tool is provided with a moving channel for the copper wire element to be cut to pass through, and the lower cutting tool is also provided with a cutting matching groove for accommodating the cutting blade and the two auxiliary forming blocks. When the cutting blade and the two auxiliary forming blocks are located in the cutting matching groove, the interval between the edges of the cutting blade and the two auxiliary forming blocks and the edges of the cutting matching groove forms a cutting gap, and the moving channel passes through the cutting matching groove.

[0008] In one embodiment, the cutting length L of the cutting blade is set to 4 mm, and the cutting gap is set in the range of 0.15-0.2 mm.

[0009] In one embodiment, the thickness of the two auxiliary forming blocks is flush with that of the cutting blade, and the cutting blade and the two auxiliary forming blocks are integrally formed.

[0010] In one embodiment, the connection between the cutting blade and the two auxiliary forming blocks is arranged in an arc shape.

[0011] In one embodiment, the cutting edge inclination angle of the cutting blade is set to 45-55 degrees.

[0012] In one embodiment, the cut-off fitting groove comprises:

[0013] A blade receiving groove, the blade receiving groove is used to receive the cutting blade;

[0014] And, a forming block accommodating groove, wherein the forming block accommodating groove is used to accommodate the two auxiliary forming blocks, and the forming block accommodating groove is communicated with the blade accommodating groove.

[0015] In one embodiment, the blade receiving groove and the forming block receiving groove are both provided with cutting edges at their openings.

[0020] The beneficial effects brought by the technical solution provided in the embodiments of the present application include:

[0021] By adding auxiliary forming blocks on both sides of the cutting blade of the upper cutting tool, when the upper cutting tool is pushed by the power device to move downward to cut the copper wire element to be cut, the auxiliary forming blocks can disperse the stress on the cutting blade, reduce the wear of the cutting blade in the upper cutting tool, and at the same time, when the upper cutting tool presses down to cut the copper wire element to be cut, a cutting matching groove is opened on the moving channel of the copper wire element on the lower cutting tool to cooperate with the cutting blade to cut the copper wire element to be cut, and the cut copper wire waste can directly fall along the cutting matching groove to prevent the cut copper wire waste from staying on the moving channel and affecting the subsequent movement of the copper wire element to be cut, which is more convenient to use. There is a cutting gap between the cutting blade and the edges of the two auxiliary forming blocks and the cutting matching groove. By adding the cutting gap, not only a buffer space is provided for possible minor errors in the cutting process, and the mechanical wear that may be caused by excessively high requirements for precise alignment is reduced, but also the service life of the cutting blade and the two auxiliary forming blocks is further extended by reducing unnecessary friction and collision between the cutting blade and the edges of the two auxiliary forming blocks and the cutting matching groove. The invention solves the problem of short service life of the upper cutting knife die and the lower cutting knife die in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The embodiment of the present application provides a long-life copper wire element cutting tool, which can solve the problem of short service life of the upper cutting knife die and the lower cutting knife die in the prior art.

[0029] Reference Figure 1 and Figure 2 The present application discloses a high-life copper wire element cutting tool, comprising an upper cutting tool 1 and a lower cutting tool 2. The upper cutting tool 1 is provided with a cutting blade 11, and both sides of the cutting blade 11 in the length direction are connected with auxiliary forming blocks 12, so that when the cutting blade 11 cuts downwardly the copper wire element 3 to be cut, when the cutting blade 11 is subjected to the reaction force from the copper wire element 3 to be cut, the reaction force on the surface of the cutting blade 11 can be diffused toward the auxiliary forming block 12, and the auxiliary forming block 12 can share the reaction force from the copper wire element 3 to be cut for the cutting blade 11, so that the reaction force can be more evenly dispersed on the cutting blade 11, thereby reducing the possibility that the cutting blade 11 is easily broken due to the concentrated support force; and the cross-sectional size S of the auxiliary forming block 12 gradually increases from the end close to the cutting blade 11 to the end away from the cutting blade 11, and the cross-sectional size S of the auxiliary forming block 12 is gradually increased ... The larger the size S is, the larger the sharing area can be provided for the cutting blade 11, thereby providing support for the cutting blade 11, reducing the burden of the copper wire element 3 to be cut on the cutting blade 11, so as to extend the service life of the cutting blade 11; and when the cutting blade 11 and the two auxiliary forming blocks 12 are located in the cutting matching groove 22, the interval between the edges of the cutting blade 11 and the two auxiliary forming blocks 12 and the edges of the cutting matching groove 22 forms a cutting gap, which provides a buffer space for minor errors that may exist during the cutting operation, reduces the mechanical wear that may be caused by excessively high requirements for precise alignment, and reduces unnecessary friction and collision between the edges of the cutting blade 11 and the two auxiliary forming blocks 12 and the cutting matching groove 22, further extending the service life of the cutting blade 11 and the two auxiliary forming blocks 12, and solves the problem of short service life of the upper cutting die and the lower cutting die in the prior art.

[0030] More specifically, the upper cutting tool 1 is provided with four bolt holes for connecting to the power device, so that when the copper wire element 3 to be cut is cut, the upper cutting tool 1 can be fixed to the power device, so that the power device can drive the upper cutting tool 1 to press down at a uniform speed to achieve the cutting operation of the copper wire element 3 to be cut. The power device can select a hydraulic cylinder or a telescopic cylinder according to the actual working conditions. The two auxiliary forming blocks 12 are flush with the thickness of the cutting blade 11, and the cutting blade 11 and the two auxiliary forming blocks 12 are made in one piece, eliminating the possible gap between the cutting blade 11 and the two auxiliary forming blocks 12, so that the connection between the cutting blade 11 and the two auxiliary forming blocks 12 is tighter, and the structural strength is stronger, thereby providing a more stable support force for both ends of the cutting blade 11, and can assist the cutting blade 11 in forming and cutting the copper wire element 3 to be cut.

[0031] In one embodiment of the present application, the cutting length L of the cutting blade 11 in the upper cutting tool 1 is set to 4mm, and the range of the cutting gap is specifically set between 0.15-0.2mm. By increasing the length of the cutting gap, the mechanical wear that may be caused by the high requirement for precise alignment is reduced, and the reaction force of the copper wire element 3 to be cut on the cutting blade 11 when being cut is reduced, thereby extending the service life of the cutting blade 11. Further, the edge width setting can be adjusted between 0.3-0.4mm, the edge height can be set between 0.4-0.5mm, and the edge inclination angle of the cutting blade 11 can be set between 45-55 degrees. The specific numerical setting of the cutting blade can be flexibly adjusted according to the actual strength of the copper wire element 3 to be cut and the cutting requirements.

[0032] Furthermore, the connection between the cutting blade 11 and the two auxiliary forming blocks 12 is arranged in an arc shape, so that the connection between the cutting blade 11 and the auxiliary forming blocks 12 is smoother, thereby reducing the possibility of fracture between the cutting blade 11 and the auxiliary forming blocks 12.

[0033] Reference Figure 1 and Figure 3The lower cutting tool 2 is provided with a moving channel 21 for the copper wire element 3 to be cut to pass through. When the copper wire element 3 to be cut is cut, the copper wire element 3 to be cut moves through the moving channel 21 at a uniform speed; the moving channel 21 passes through the cutting matching groove 22, and the lower cutting tool 2 is provided with a cutting matching groove 22 for accommodating the cutting blade 11 and the two auxiliary forming blocks 12, so that when the upper cutting tool 1 is slowly pressed down, the cutting blade 11 and the two auxiliary forming blocks 12 can cooperate with the cutting matching groove 22 to cut the copper wire element 3 to be cut, and when the upper cutting tool 1 is pressed down, the cutting blade 11 and the two auxiliary forming blocks 12 can extend into the cutting matching groove 22, so that the cut copper wire waste can pass through the cutting matching groove 22, which will not affect the subsequent copper wire element 3 to be cut from the moving channel 21, and it is more convenient to use.

[0034] More specifically, refer to Figure 3 The cutting matching groove 22 includes a blade accommodating groove 221 and a forming block accommodating groove 222. The blade accommodating groove 221 is used to accommodate the cutting blade 11, and the forming block accommodating groove 222 is used to accommodate two auxiliary forming blocks 12. When the cutting blade 11 and the two auxiliary forming blocks 12 are located in the blade accommodating groove 221 and the forming block accommodating groove 222, there is a cutting gap of 0.15-0.2mm between the edges of the blade accommodating groove 221 and the forming block accommodating groove 222 and the edges of the cutting blade 11 and the two auxiliary forming blocks 12, and the forming block accommodating groove 222 is communicated with the blade accommodating groove 221, so that the cutting matching groove 22 can cooperate with the cutting blade 11 and the two auxiliary forming blocks 12 to complete the cutting of the copper wire element 3 to be cut.

[0035] Furthermore, the notches of the blade receiving groove 221 and the forming block receiving groove 222 are both provided with cutting edges to cooperate with the cutting blade 11 to cut the copper wire element 3 to be cut, which is more convenient to use.

[0036] In order to further facilitate the installation of the two auxiliary forming blocks 12, a guide block 13 is also provided on the upper cutting tool 1. Two guide blocks 13 are also provided, and each auxiliary forming block 12 is connected to one end away from the cutting blade 11 with a guide block 13. The corresponding guide block 13 on the lower cutting tool 2 is also provided with a guide receiving groove 23 for accommodating the guide block 13, so as to cooperate with the two guide blocks 13 to drive the two auxiliary forming blocks 12 and the cutting blade 11 to be pressed down.

[0037] In order to make the upper cutting tool 1 and the lower cutting tool 2 cooperate to cut the copper wire element 3 to be cut more accurately and reduce the possibility of slipping of the copper wire element 3 to be cut during the cutting operation, a clamping channel 14 for a clamping device to pass through is provided on the upper cutting tool 1 and the lower cutting tool 2. The clamping channel 14 includes an upper clamping channel 141 provided on the upper cutting tool 1 and a lower clamping channel 142 on the lower cutting tool 2. When the copper wire element 3 to be cut is cut, an external clamping device, such as a guide post spring connected to the telescopic end of the hydraulic cylinder, is passed through the upper clamping channel 141 and the lower clamping channel 142. The hydraulic cylinder is turned on to move the guide post spring toward the direction of the copper wire element 3 to be cut, and the copper wire element 3 to be cut is temporarily fixed when the upper cutting tool 1 presses down to cut the copper wire element 3 to be cut, thereby reducing the possibility of slipping of the copper wire element 3 to be cut and making it more convenient to use.

[0038] More specifically, there are two upper clamping channels 141, and the two upper clamping channels 141 are respectively opened at the two ends of the cutting blade 11 along the moving extension direction of the copper wire element 3 to be cut, and there are also two lower clamping channels 142, and the two lower clamping channels 142 are arranged on the moving channel 21 at the two ends of the blade accommodating groove 221 along the moving extension direction of the copper wire element 3 to be cut, thereby temporarily clamping the copper wire element 3 to be cut.

[0039] Furthermore, when manufacturing the upper cutting tool 1 and the lower cutting tool 2, in order to ensure that the upper cutting tool 1 and the lower cutting tool 2 can meet the requirements of efficient and accurate cutting and extend their service life, high-strength steel materials can be selected for production. After proper heat treatment, the high-strength steel can significantly improve the hardness, so that the upper cutting tool 1 and the lower cutting tool 2 can resist the friction and wear generated during the cutting process, thereby extending the service life of the upper cutting tool 1 and the lower cutting tool 2. This is particularly important for scenarios where hard materials need to be cut frequently. In addition, the high-strength steel material also has sufficient toughness, which means that the upper cutting tool 1 and the lower cutting tool 2 are not easy to break when subjected to impact or pressure, ensuring the continuity and safety of the cutting operation of the copper wire element 3 to be cut. In addition, the high-strength steel material also has excellent fatigue resistance, which can effectively reduce the failure of the upper cutting tool 1 and the lower cutting tool 2 caused by material fatigue, and ensure cutting efficiency and quality.

[0040] Therefore, when manufacturing the upper cutting tool 1 and the lower cutting tool 2, the use of high-strength steel materials can not only significantly increase the service life of the upper cutting tool 1 and the lower cutting tool 2, but also reduce long-term operating costs while ensuring cutting efficiency and accuracy. Of course, according to the specific application scenario and the characteristics of the cutting material, other factors need to be considered comprehensively, such as the design of the tool, the manufacturing process, and whether special coating treatment is required, in order to maximize the overall performance and life of the upper cutting tool 1 and the lower cutting tool 2.
