Description

Technical Field

[0001] This utility model relates to the field of alloy resistor processing, and in particular to a cutting device suitable for alloy resistor raw materials. Background Technology

[0002] Figure 1 This is a schematic diagram of the processing flow for alloy resistor raw materials. The raw materials for alloy resistors are in strip form. Before processing the raw materials into alloy resistors, a cutting operation is required. Specifically, the strip 21 is first divided into multiple plates 22 of equal length. Then, the edges of the plates 22 are trimmed, the width of the plates 22 is adjusted, and finally, positioning holes 23 are punched into the plates 22, completing the cutting operation. The cut plates 22 are then transferred to other equipment for further processing into alloy resistors.

[0003] In the above-mentioned cutting process, after the raw material is divided into multiple plates 22 of equal length, it is necessary to trim them to adjust the width of the plates 22, and to punch positioning holes 23 in the plates 22 so that the alloy resistor processing equipment can position the plates 22 and process them to obtain alloy resistors.

[0004] The blanking process is the raw material processing stage for alloy resistors. As can be seen from the above blanking process, the blanking process alone requires three steps, and the raw material needs to be transferred between each step. The blanking process is too long, which is not conducive to improving the processing efficiency of alloy resistors. Utility Model Content

[0034] Please see Figure 2 This utility model provides a cutting device 10 suitable for alloy resistance raw materials, which includes: a hydraulic cylinder 100, a guide bracket 200, a jig 300 and a pressing component 400.

[0035] Please see Figure 2 and Figure 3 The hydraulic cylinder 100 and the fixture 300 are located at both ends of the guide bracket 200. The hydraulic cylinder 100 is used to drive the pressing component 400 to move closer to or further away from the fixture 300 along the guide bracket 200, so that the pressing component 400 moves up and down along the guide bracket 200. When the pressing component 400 moves down, it punches and shapes the plate 22 placed on the fixture 300, and trims the alloy resistor raw material to the target size.

[0036] Please see Figure 3 The fixture 300 is provided with a support platform 310 and two opposing limiting blocks 320. The support platform 310 is used to accommodate the alloy resistor material to be trimmed. The limiting blocks 320 are in contact with the edge of the alloy resistor material. The support platform 310 has two cutting grooves 311. The part of the alloy resistor material to be trimmed is suspended on the cutting grooves 311. When clamping the plate 22, the plate 22 is placed between the two limiting blocks 320 and the edge to be trimmed is suspended on the cutting grooves 311. When the pressing component 400 presses down, it will cut off the part of the plate 22 suspended in the opening of the cutting grooves 311, thereby trimming the width of the plate 22 to the target width.

[0037] Please see Figure 4 and Figure 5The pressing assembly 400 includes a main board 410, a pressure plate 420, and a buffer rod 430, a spring 440, a cutter 450, and a punch 460 located within the pressure plate 420. The main board 410 has a guide hole 411 that matches the guide bracket 200. The buffer rod 430 is slidably mounted on the pressure plate 420. The spring 440 pushes the buffer rod 430 to extend out of the pressure plate 420. The cutter 450 and the punch 460 both face the support platform 310, and the cutter 450 is closer to the support platform 310 than the punch 460. When the pressing assembly 400 contacts the fixture 300, the cutter 450 cuts the edge of the alloy resistor material and penetrates into the cutting groove 311.

[0038] Please see Figure 4 and Figure 5 In this process, the cutter 450 is aligned with the receiving groove 311. After the pressing component 400 and the fixture 300 come together, the cutter 450 will be inserted into the receiving groove 311 and cut off the part of the plate 22 that is suspended in the opening of the receiving groove 311. The length of the cutter 450 is greater than the length of the punch 460. After the cutter 450 cuts off the edge material on the plate 22 and extends into the receiving groove 311, the punch 460 contacts the plate 22 and punches a positioning hole 23 on the plate 22.

[0039] Please see Figure 5 , Figure 6 and Figure 7 The specific process of the cutting device 10 for alloy resistor raw materials for trimming and punching is as follows:

[0040] It should be noted that the alloy resistor raw material mentioned in this application refers to a composite metal material formed by rolling. Its structure is a thin and long strip 21. Before using this material to make alloy resistors, the raw material needs to be divided into plates 22 of fixed size, and positioning holes 23 are opened on the plates 22 to facilitate the positioning and processing operations of subsequent equipment. The cutting process requires first dividing the strip 21 into multiple plates 22 of equal length. The length of the divided plates 22 meets the standard, but the width of the plates 22 does not meet the standard. It needs to be trimmed to a fixed size to ensure that the equipment in the subsequent processing station can properly position the plates 22. The cutting device 10 for alloy resistor raw materials claimed in this application is mainly responsible for trimming the width of the newly divided plates 22 and processing the positioning holes 23 on the plates 22.

[0041] It is known that the length of the plate 22 has reached the standard after the initial cutting. When clamping the plate 22, the two cut edges on the plate 22 are used as reference edges to make it fit against the limiting block 320 for positioning. The two edges in the width direction of the plate 22 will be suspended on the opening of the knife groove 311.

[0042] Hydraulic cylinder 100 drives the lowering assembly 400 to descend, and buffer rod 430 first contacts plate 22, pressing plate 22 firmly. Figure 5 As shown, to prevent the board 22 from shifting; then the cutter 450 contacts the board 22 and cuts off the portion of the board 22 suspended above the opening of the cutter groove 311. At this time, the width of the board 22 is trimmed to the target length, and the cutter 450 will further penetrate into the cutter groove 311, with the outer wall of the cutter 450 adhering to the trimmed surface of the board 22, as shown. Figure 7 As shown, at this time, the cutter 450 and the limiting block 320 cooperate to restrict the four sides of the plate 22, preventing the plate 22 from shifting laterally. The buffer rod 430, under the action of the spring 440, holds the plate 22 in place, preventing it from jumping. In this state, the punching needle 460 punches the positioning hole 23 into the plate 22. Figure 7 As shown.

[0043] The cutting device 10 suitable for alloy resistance raw materials has the following beneficial effects:

[0044] 1. The trimming of the board 22 and the processing of the positioning holes 23 are completed on the same equipment, which helps to improve the cutting efficiency.

[0045] 2. The cutter 450 performs the trimming operation, and the cutter 450 contacts the plate 22 before the punching pin 460. This allows the plate 22 to be positioned after the edge material is removed, preventing the plate 22 from shifting during the punching process, ensuring the positional accuracy of the positioning hole 23, and eliminating the need to re-clamp the plate 22. This further improves the cutting efficiency and helps to shorten the processing flow of the alloy resistor.

[0046] 3. Before the cutter 450 trims the edge material on the board 22, the buffer rod 430 holds the board 22 down to improve the accuracy of edge material removal.

[0047] In one embodiment, the number of cutters 450 is the same as the number of slots 311, and the thickness of the cutters 450 is the same as the width of the slots 311, which improves the accuracy of edge material removal and reduces the probability of burrs forming on the plate 22 after the cutters 450 punch.

[0048] Please see Figure 5 In one embodiment, a positioning surface 451 is provided on the side of the cutter 450 near the center of the support platform 310. After the cutter 450 extends into the knife groove 311, the positioning surface 451 fits against the edge of the plate 22, providing a limit to the plate 22 and preventing the plate 22 from shifting during subsequent punching operations.

[0049] Please see Figure 5In one embodiment, the cutting groove 311 penetrates the support platform 310. The support platform 310 has a discharge hole 312, and the punching pin 460 is aligned with the discharge hole 312. The fixture 300 also includes a collection box 330 located below the support platform 310. The collection box 330 is used to receive waste material falling from the discharge hole 312 and the cutting groove 311. Waste material generated by the cutting blade 450 and the punching pin 460 can fall into the collection box 330, facilitating the cleaning of waste generated during the processing.

[0050] Please see Figure 5 In one embodiment, the pressure plate 420 has a clearance hole 421, and the buffer rod 430 is disposed in the clearance hole 421. A soft pad 431 is provided on the end of the buffer rod 430 facing the fixture 300, and the soft pad 431 is used to adhere to the alloy resistance material. This increases the friction between the buffer rod 430 and the plate 22, preventing deviation during punching of the plate 22, and the soft pad 431 reduces the impact force of the buffer rod 430 on the plate 22, preventing scratches on the surface of the plate 22.

[0051] Please see Figure 5 In one embodiment, the cutter 450 is provided with a cutting portion 452, and the thickness of the cutting portion 452 increases from the side facing the fixture 300 to the side connected to the pressure plate 420.

[0052] Please see Figure 2 In one embodiment, the cutting device 10 suitable for alloy resistance raw materials also includes a control box 500. The control box 500 is located on the edge of the support platform 310. The control box 500 is equipped with an emergency stop button and a start button. When the equipment malfunctions, the operator can start or stop the equipment through the emergency stop button and the start button on the control box 500.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
