Description

Technical Field

[0001] This utility model relates to the field of disc shear processing, and in particular to a processing fixture for disc shears. Background Technology

[0002] Disc shears are a type of cutting tool used in sock knitting machines. In the production process, several raw materials are typically stacked and fixed, and then triangular blades are machined using molybdenum wire. Because the circular edge of the disc shears has a ring of blades, when the molybdenum wire rotates 360 degrees to complete the processing of the disc shears, a notch is also cut into the base plate used to hold the raw materials. This means that the base plate needs to be replaced when processing the next batch of raw materials, which is inconvenient to operate and also not conducive to saving materials. Utility Model Content

[0003] The purpose of this invention is to provide a processing fixture for a disc shear. After fixing the raw material, the molybdenum wire is processed 180 degrees first, then paused, the raw material is rotated 180 degrees, and then processing continues. It has the advantages of convenient operation and no need to replace the base plate.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A machining fixture for a disc shear includes an installation frame and at least one tooling roller. A limiting plate is fixedly provided at the bottom of the tooling roller, and a second limiting plate is detachably connected to the top of the tooling roller. Both the top and bottom surfaces of the tooling roller are provided with protruding shafts. One side of the top and bottom plates of the installation frame is provided with an installation notch corresponding to each tooling roller, and both sides of the top and bottom plates of the installation frame are provided with movable notches for cooperating with the movement of molybdenum wires. After the two protruding shafts of the tooling roller are inserted into the corresponding installation notches, the tooling roller can rotate around its own axis. A limiting component that can restrict the rotation of the tooling roller can also be detachably connected inside the installation notch. The installation frame is also provided with an adjustment component corresponding to each tooling roller, and the adjustment component can rotate the tooling roller 180 degrees.

[0006] Using the above technical solution, the raw material is first installed onto the tooling roller, then the tooling roller is installed onto the mounting frame, then the limiting component is installed to limit the rotation of the tooling roller, and then processing begins. After the molybdenum wire is processed 180 degrees, the equipment is paused, the component is adjusted to make the tooling roller rotate 180 degrees, and finally the molybdenum wire continues to process the remaining part.

[0007] Preferably, the limiting component includes a limiting block and an adjusting block. The width of the limiting block and the adjusting block are both equal to the width of the mounting notch. The side of the limiting block closest to the tooling roller is in a matching arc shape. The two sides of the adjusting block and the inner walls of the two sides of the mounting notch are provided with matching protrusions and slots. The adjusting block is also provided with a threaded through hole, and a bolt is provided in the threaded through hole.

[0008] By using the above technical solution, rotating bolt one causes it to contact the limiting block, which in turn presses the protruding shaft, thus restricting the rotation of the tooling roller.

[0009] Preferably, the adjustment component includes a connecting block and a pin. The connecting block and the protruding shaft are detachably connected. One end of the connecting block is provided with a first insertion hole that matches the pin. The top surface of the mounting frame is provided with a second insertion hole and a third insertion hole, and the second insertion hole and the third insertion hole are spaced 180 degrees apart.

[0010] Using the above technical solution, after the molybdenum wire is processed 180 degrees, the equipment is paused, the connecting block is installed on the upper protruding shaft, and then the connecting block is rotated to align the first and second insertion holes. The pin is inserted to fix the connecting block and the protruding shaft. Then, the two bolts are loosened, the pin is pulled out, the connecting block is rotated to drive the tooling roller to rotate until the first and third insertion holes are aligned. The pin is then inserted, the two bolts are tightened again, the pin is pulled out, and the connecting block is removed.

[0011] Preferably, the upper protruding shaft protrudes through the mounting frame, the connecting block is provided with a through hole that matches the protruding shaft, and the connecting block is provided with a dividing slit on both sides of the through hole to connect the through hole. The dividing slit away from the insertion hole one divides the corresponding part of the connecting block into connecting part one and connecting part two, and bolt two is also provided between connecting part one and connecting part two.

[0012] By using the above technical solution, tightening bolt two will fix the connecting block and the protruding shaft together.

[0013] Preferably, the adjustment component is a servo motor, with the upper protruding shaft protruding through the mounting frame, and both the protruding part of the protruding shaft and the output shaft of the servo motor are equipped with gears, and a gear belt is provided between the two gears.

[0014] Using the above technical solution and employing a servo motor, when adjusting the angle, simply loosen bolt one first, and after the servo motor drives the tooling roller to rotate 180 degrees, tighten bolt one again.

[0015] Preferably, the molybdenum wire is kept on the outside of the gear belt during processing.

[0016] Using the above technical solution, the gear belt does not affect the movement of the molybdenum wire.

[0017] Preferably, the tooling roller may also be fitted with several sleeves of different heights.

[0018] Using the above technical solution, because sometimes the amount of raw materials being processed is small, the second limiting plate and the first limiting plate cannot press the raw materials tightly, so several sleeves of different heights can be fitted onto the tooling roller. Depending on the specific amount of raw materials, the sleeves are fitted to replace part of the raw materials, ensuring that the second limiting plate and the first limiting plate press the raw materials tightly.

[0019] Preferably, the diameter of the sleeve is smaller than the diameter of the raw material, and the molybdenum wire is kept on the outside of the sleeve during processing.

[0020] Using the above technical solution, the sleeve does not affect the movement of the molybdenum wire. Attached Figure Description

Detailed Implementation

[0026] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model. Example

[0027] like Figure 1 and Figure 2 As shown, a processing fixture for a disc shear includes a mounting frame 1 and at least one fixture roller 2. The mounting frame 1 includes a top plate, a bottom plate, and two side plates, which are fixed together by bolts. In this embodiment, there are two fixture rollers 2. A limiting plate 21 is fixedly provided at the bottom of the fixture roller 2, and a second limiting plate 22 is detachably connected to the top of the fixture roller 2. The second limiting plate 22 is removed first, and then the overlapping raw materials are sequentially placed onto the fixture roller, and then the second limiting plate 22 is installed.

[0028] After controlling the position of the second limiting plate 22, it is installed on the tooling roller 2 and, together with the first limiting plate 21, presses the raw material tightly. Sometimes, because the quantity of raw material being processed is small, the second limiting plate 22 and the first limiting plate 21 may not be able to press the material tightly enough. Therefore, several sleeves of different heights can be fitted onto the tooling roller 2. Depending on the quantity of raw material, the sleeves are inserted to replace part of the material, ensuring that the second limiting plate 22 and the first limiting plate 21 press the material tightly. The diameter of the sleeve is smaller than the diameter of the raw material, and during processing, the molybdenum wire remains on the outside of the sleeve to prevent the sleeve from interfering with the processing.

[0029] The tooling roller 2 has protruding shafts 23 on both its top and bottom surfaces. The top and bottom plates of the mounting frame 1 have mounting notches 011 on one side corresponding to each tooling roller 2. The top and bottom plates of the mounting frame 1 also have moving notches 012 on both sides of the mounting notches 011 to accommodate the movement of the molybdenum wire. One end of the mounting notch 011 is arc-shaped to fit the protruding shaft 23. The two protruding shafts 23 of the tooling roller 2 are inserted into the corresponding mounting notches 011, and the mounting notches 011 and the arc-shaped end are aligned. At this point, the tooling roller 2 can rotate around its own axis.

[0030] A detachable limiting component that restricts the rotation of the tooling roller 2 is also detached within the mounting notch 011. This limiting component is installed after the tooling roller is mounted onto the mounting frame 1. The limiting component includes a limiting block 3 and an adjusting block 4, both with widths equal to the width of the mounting notch 011. The limiting block 3 has a matching arc shape on the side closest to the tooling roller 2. The limiting block 3 is inserted into the mounting notch 011 and can move back and forth within it. The two sides of the adjusting block 4 and the inner walls of the two sides of the mounting notch 011 have matching protrusions and slots, restricting its movement after insertion. The adjusting block 4 also has a threaded through hole 62 with a bolt 5 inside. Rotating the bolt 5 causes it to abut against the limiting block 3, pressing the limiting block 3 against the protruding shaft 23, thus restricting the rotation of the tooling roller 2.

[0031] like Figure 3 As shown, the mounting frame 1 also has an adjustment component for each tooling roller 2, which includes a connecting block 6 and a pin 7. One end of the connecting block 6 has a first insertion hole 61 that mates with the pin 7. The top surface of the mounting frame 1 has two insertion holes 013 and 014, which are spaced 180 degrees apart. The upper protruding shaft 23 protrudes from the mounting frame 1. The connecting block 6 has a through hole 62 that mates with the protruding shaft 23, and the connecting block 6 has a dividing slit 63 on both sides of the through hole 62 that connects to the through hole 62. The dividing slit 63 away from the first insertion hole 61 divides the corresponding part of the connecting block 6 into connecting part one and connecting part two. A bolt 64 is also provided between connecting part one and connecting part two.

[0032] The working principle of this utility model is briefly described as follows: First, the raw material is installed onto the tooling roller, then the tooling roller 2 is installed onto the mounting frame 1. Next, the limiting component is installed, and bolt 5 is rotated to press the two protruding shafts 23 of the tooling roller 2, restricting the rotation of the tooling roller. Then, processing begins. After the molybdenum wire is processed 180 degrees, the equipment is paused. The connecting block 6 is installed onto the upper protruding shaft 23. Then, the connecting block 6 is rotated to align the insertion hole 61 and the insertion hole 013. The pin 7 is inserted, and bolt 64 is tightened. Then, the two bolts 5 are loosened, the pin 7 is pulled out, and the connecting block 6 is rotated to drive the tooling roller to rotate until the insertion hole 61 and the insertion hole 014 are aligned. The pin 7 is inserted, the two bolts 5 are retightened, bolt 64 is loosened, the pin 7 is pulled out, and the connecting block 6 is removed. Finally, the molybdenum wire continues to process the remaining part. Example

[0033] like Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the adjustment component is a servo motor, which is fixedly connected to the mounting frame 1. The upper protruding shaft 23 extends through the mounting frame 1, and both the protruding portion of the protruding shaft 23 and the output shaft of the servo motor are equipped with gears, with a gear belt between the two gears. A gear of suitable size is selected, and during processing, the molybdenum wire remains on the outside of the gear belt. Using a servo motor, when adjusting the angle, it is only necessary to first loosen bolt 5, allow the servo motor to rotate the tooling roller 180 degrees, and then retighten bolt 5. Compared to Embodiment 1, the operation is more convenient, but the volume of the mounting frame 1 is correspondingly increased. A suitable implementation method can be selected according to specific circumstances.
