Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a cutting device for the production of inductor coils. Background Technology

[0002] The production of inductor coils typically includes winding, fixing, insulation treatment, and cutting. During winding, the conductor is wound onto the bobbin according to the designed number of turns using an automatic winding machine to form the coil structure. It is then fixed by applying glue or binding wire to ensure structural stability. Next, it is impregnated with varnish or coated with insulating material to improve its withstand voltage and temperature performance. After that, the coil is cut from the bobbin, and finally, after deburring, cleaning, and testing, the finished product is completed.

[0003] Chinese patent discloses a cutting device for inductor coils (publication number: CN221715544U). This device mounts the main body to a corresponding position using fixing bolts, aligning the cutter with the coil to be cut. A control device controls a motor to rotate a threaded rod, simultaneously causing a pulling component to move closer to the main body. During this process, the pulling component pushes a push rod, actuating the corresponding cutter. The two sets of cutters operate on the same principle, thus cutting the coil at the corresponding position. It can be used with coil winding equipment. When the pulling component is removed, manual operation involves simultaneously squeezing both sets of push rods to directly actuate the cutter for coil cutting. It is suitable for manual coil processing. However, this device still has the following problems:

[0004] In the above-mentioned device, when manually controlling the cutting blade to cut the inductor coil, it is necessary to push both blades at the same time, which is not labor-saving. When the force applied by the two blades is uneven, and the coil is squeezed by the two blades in different directions, the central area of ​​the coil is easily stretched and deformed, resulting in uneven cuts and an unsightly cut. It can also easily lead to local cracking of the insulation layer. Therefore, a cutting device for inductor coil production is proposed to solve the above problems. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cutting device for producing inductor coils includes a guiding mechanism, the upper end of which is provided with two cutting mechanisms;

[0007] The cutting mechanism includes a mounting plate, which has through holes on both the front and back sides. There are two through holes in total, and the two through holes are located on the same vertical line. Positioning recesses are provided on the surface of the mounting plate on both sides of the through holes. Each positioning recess extends vertically, and the lower end of the positioning recess extends to the bottom surface of the mounting plate.

[0008] The mounting plate has a blade on one side and an anvil on the other side, with the thickness of the anvil being greater than the thickness of the blade.

[0009] As a further embodiment of this utility model: the guiding mechanism includes a bracket, and mounting seats are fixedly installed at the lower ends of the front and back sides of the bracket, with bolt holes opened in the middle and on both sides of the surface of each mounting seat.

[0010] As a further embodiment of this utility model: guide grooves are provided on both the front and back of the bracket, each guide groove extends in a horizontal direction, and lower positioning holes are symmetrically provided on the surface of the bracket below each guide groove.

[0011] As a further embodiment of this utility model: the inner wall of the bracket is provided with a receiving opening in the middle, and sliders are slidably connected to both sides of the inner wall of the receiving opening. Guide plates are fixedly installed on the lower ends of the front and back sides of each slider. Each guide plate is slidably connected to the inner side of the adjacent guide groove. Each guide plate is provided with an upper positioning hole on its surface.

[0012] As a further embodiment of this utility model: a handle is fixedly installed on the side of adjacent guide plates, the handle being located outside the bracket, and an installation plate is fixedly installed on the side of the slider and above the handle.

[0013] As a further embodiment of this utility model: each of the sliders has two mounting holes in the middle of its front and back sides, and the two mounting holes are located on the same vertical line. The inner wall of the slider is also provided with a clamping groove, and the two sides of the inner wall of the clamping groove are symmetrically fixedly connected with positioning protrusions.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model fixes the mounting plate by inserting it into the clamping grooves in the sliders on both sides. A blade is provided on one side of the mounting plate and an anvil is provided on the other side. When manually cutting the coil, the blade and anvil are respectively placed on both sides of the coil to form a single-blade pliers structure. Then, the coil can be cut by pushing the blade on one side, which is more labor-saving. In addition, the sharp blade on one side can reduce the deformation of the compression. Similar to the "cutting" action, it can ensure that the cut is flat, which is suitable for fine cutting of thin wires and other materials that require manual operation.

[0017] 2. The outer side of the slider can be connected to the extension end of the drive components such as the cylinder through the mounting plate and fasteners such as bolts, so as to control the sliders on both sides to retract at the same time. When fixing the mounting plate, it is suitable to point the blades on both sides towards the cutting coil at the same time, and the double-sided blade edge squeezes and cuts, similar to the "scissor" action. The squeeze cutting speed is fast and suitable for batch processing. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, a cutting device for inductor coil production includes a guiding mechanism 1, with two cutting mechanisms 2 disposed at the upper end of the guiding mechanism 1. Each cutting mechanism 2 includes a mounting plate 201. Two through holes 203 are provided on both the front and back sides of the mounting plate 201, and both through holes 203 are located on the same vertical line. Positioning recesses 202 are provided on the surface of the mounting plate 201 on both sides of the through holes 203. Each positioning recess 202 extends vertically, and its lower end extends to the bottom surface of the mounting plate 201. A blade 204 is provided on one side of the mounting plate 201, and an anvil 205 is provided on the other side of the mounting plate 201. The thickness of the anvil 205 is greater than the thickness of the blade 204. Figure 5 As shown, the thickness of the blade 204 is between 1.5 mm and 2 mm, while the thickness of the cutting board 205 is at least 6 mm.

[0027] The guide mechanism 1 includes a bracket 101, and mounting seats 102 are fixedly installed on the lower ends of both the front and back sides of the bracket 101. Bolt holes are formed in the center and on both sides of the surface of each mounting seat 102. Figures 1-2 As shown, the bolt passes through the bolt hole and is fixed on the support plane, so the bracket 101 remains relatively fixed relative to the operating environment;

[0028] The bracket 101 has guide grooves 103 on both its front and back sides, each extending horizontally. Symmetrical lower positioning holes 104 are formed on the surface of the bracket 101 below each guide groove 103. A receiving opening 105 is formed in the center of the inner wall of the bracket 101. Sliding sliders 106 are slidably connected to both sides of the inner wall of the receiving opening 105. Guide plates 107 are fixedly installed at the lower ends of the front and back sides of each slider 106. Each guide plate 107 is slidably connected to the inner side of the adjacent guide groove 103. Upper positioning holes 108 are formed on the surface of each guide plate 107. Figure 2 As shown, the bolt can pass through both the lower positioning hole 104 and the upper positioning hole 108 simultaneously;

[0029] A handle 109 is fixedly installed on the side of adjacent guide plates 107. The handle 109 is located outside the bracket 101. A mounting plate 110 is also fixedly installed on the side of the slider 106, above the handle 109. Figure 2 As shown, the mounting plate 110 has a flange structure, which facilitates fixing to the extension end of external equipment such as cylinders using fasteners;

[0030] Each slider 106 has two mounting holes 113 in the center of its front and back sides. Both mounting holes 113 are located on the same vertical line. A clamping groove 111 is also provided in the center of the inner wall of the slider 106. Positioning protrusions 112 are symmetrically fixed to both sides of the inner wall of the clamping groove 111. The inside of the clamping groove 111 is inserted into the mounting plate 201. The positioning protrusions 112 slide along the inner side of the positioning recess 202, and the mounting holes 113 are aligned with the through holes 203. Figures 3-5 As shown, when connecting the mounting plate 201 and the slider 106, the mounting plate 201 is inserted into the clamping groove 111 from top to bottom, so that the positioning protrusion 112 slides along the positioning recess 202, thereby facilitating the alignment of the mounting hole 113 and the through hole 203. Finally, fasteners such as screws are inserted into the mounting hole 113 and the through hole 203, and the screw threads are locked inside the slider 106, thereby limiting the mounting plate 201.

[0031] The working principle of this utility model:

[0032] When the device is in use, the mounting base 102 is placed in the designated position, and the bolts are passed through the mounting base 102 and then fixed on the support plane. After the wire is wound on the skeleton according to the designed number of turns by the automatic winding machine, the wire passes through the mounting plates 201 on both sides and waits for cutting.

[0033] The extension ends of the external cylinders and other drive components are fixed to the surface of the mounting plate 110 with bolts. By controlling the two cylinders, the mounting plates 201 on both sides can be controlled to close or open respectively. When fixing the mounting plate 201, it is necessary to ensure that the blades 204 on both sides are facing the coil wire. When the cylinder closes the mounting plate 201 in the air, the two blades squeeze the coil wire at the same time, thereby achieving rapid cutting.

[0034] In addition, when manual fine cutting is required, to ensure that the mounting plate 201 is fixed, the blade 204 and the anvil 205 are respectively installed on both sides of the coil wire, and the slider 106 below the corresponding anvil 205 is fixed to the bracket 101. When fixing, the bolt is passed through the lower positioning hole 104 and the upper positioning hole 108, and then the nut is tightened on the end of the bolt, so that the anvil 205 is relatively fixed with the operating environment. The operator only needs to push the handle at the position of the blade 204 to drive the single blade to cut the coil wire under the support of the anvil.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
