Description

Technical Field

[0001] The invention relates to the field of processing of lint stripping saw blades, and in particular to a device and method for laser processing chiseling teeth of lint stripping saw blades. Background Art

[0002] After the cleaned cotton seeds enter the working box of the delinting machine, they are formed into cotton seed rolls under the action of the high-speed rotating saw blade. The cotton seeds enter the working point through the hooking and pulling action of the saw teeth. The linear speed difference between the saw blade roller and the cotton seed roll and the damping effect of the row of strips are used to separate the short lint from the cotton seeds. The saw blade should be milled and filed after working for 24 hours to keep the saw teeth sharp to ensure production and quality. The saw blade after milling and filing should maintain the original tooth shape and the sharpness of the front edge, and should be sanded to remove the burrs on the saw teeth caused by milling and filing, otherwise it will increase white stars and iron impurities in the short lint. If the saw blade is found to have reversed teeth during use, it should be repaired in time. If there are many broken teeth continuously, the saw blade should be replaced.

[0003] At present, the processing method of depilatory saw blades is mostly based on traditional equipment chiseling. This processing method has a single equipment and poor precision. Depilatory saw blades have more teeth than woodworking saw blades, and the processing accuracy of the chiseling equipment needs to be accurately controlled. During the long-term processing of the equipment, the tool continues to wear, and the accumulated errors of each tooth can easily cause the last tooth to be missing, broken, or half a tooth. Each processing is a single tooth processing, which is inefficient, has large errors, and cannot be automated. The Chinese patent (application number: CN201920843925.0) designs a method of using a robot to automatically pick up and place saw blades for fully automated chiseling, but does not change the actual single-tooth processing principle. In the process of large-scale processing, the errors caused by the wear of the chiseling tool are becoming more and more serious. Summary of the invention

[0004] The purpose of the present invention is to provide a device and method for laser processing and chiseling teeth of a depilatory saw blade in view of the defects of the prior art. The laser is used to pre-roughly process the saw teeth of the depilatory saw blade, and after cooling, the saw teeth are finely processed in combination with a chiseling tool. A plurality of continuously distributed chiseling protrusions are arranged on the chiseling tool, and a plurality of saw teeth are chiseled at the same time to reduce processing errors such as missing teeth and half teeth, thereby improving processing accuracy and processing efficiency.

[0006] It includes a laser component, a rotating support and a chiseling tool. A clamp is installed on the rotating support. The clamp forms an annular clamping part for accommodating a stripping saw blade. The output end of the laser component faces the edge of the annular clamping part and is used to calibrate the position of the saw teeth of the stripping saw blade and perform rough processing. The chiseling tool is connected to the reciprocating motion mechanism and is arranged on one side of the annular clamping part. The motion trajectory of the chiseling tool is parallel to the axis of the annular clamping part. The chiseling tool is provided with continuously arranged chiseling protrusions that cooperate with multiple saw teeth at the same time.

[0007] Furthermore, a temperature regulating assembly is provided at the edge of the annular clamping portion, and the temperature regulating assembly includes an electromagnetic heating mechanism and a cooling mechanism. The temperature regulating mechanism and the chiseling tool are arranged at intervals and are located at the same circumferential position of the annular clamping portion.

[0008] Furthermore, the temperature regulating assembly comprises an arc-shaped action plate, and a side of the action plate facing the depilatory saw blade forms an action surface, and the electromagnetic heating mechanism and the cooling mechanism act on the depilatory saw blade through the action surface respectively to heat up or cool down the depilatory saw blade.

[0009] Furthermore, the chiseling tool comprises a chiseling tool and a tool holder, and a reciprocating motion mechanism is connected to the tool holder to drive the chiseling tool to reciprocate.

[0010] Furthermore, the chiseling cutter is provided with a plurality of replaceable ones, and the tool holder is detachably connected to the chiseling cutter, and the chiseling protrusions on different chiseling cutters have different specifications to adapt to saw teeth of different specifications.

[0011] Furthermore, the clamp includes a base plate and a pressure plate sleeved on the rotating shaft, an annular clamping portion is formed between the base plate and the pressure plate, and a fastener is provided on the rotating shaft on the side of the pressure plate away from the base plate to maintain the relative position of the base plate and the pressure plate.

[0012] Furthermore, the bottom plate and the pressure plate are both annular plates, which are coaxially sleeved on the rotating shaft and rotate synchronously with the rotating shaft. A plurality of radially distributed pressure rods are provided on the side of the pressure plate away from the bottom plate.

[0013] Furthermore, the laser assembly includes a laser head, a support arm and an adjustment seat, the adjustment seat is arranged at an interval from the rotating base, the adjustment seat is connected to the laser head through the support arm, and the laser head is suspended above the annular clamping part.

[0014] The second object of the present invention is to provide a working method of a chiseling device using a depilatory saw blade laser processing as described in the first object, comprising:

[0015] The depilatory saw blade is clamped on the rotating support through a fixture, and the laser component acts on the saw teeth to be processed for rough processing;

[0016] Rotate the depilatory saw blade so that the saw teeth after rough processing correspond to the chiseling protrusions of the chiseling tool, and fix the position of the depilatory saw blade;

[0017] The chiseling tool reciprocates to chisel the multiple saw teeth after rough machining;

[0018] The depilatory saw blade is rotated to process a corresponding group of multiple saw teeth by a chiseling tool, wherein the group of saw teeth includes at least one saw tooth processed in the previous group;

[0019] The depilatory saw blade is rotated to perform rough machining and chiseling of all teeth to be processed.

[0020] Furthermore, the laser assembly performs rough processing on all the saw teeth to be processed according to the number of saw teeth set by the depilatory saw blade, and calibrates the working position of the chiseling tool with the saw teeth after rough processing.

[0021] Compared with the prior art, the present invention has the following advantages and positive effects:

[0022] (1) In order to solve the problem that the current sawtooth distribution density of the depilatory saw blade is high, resulting in large chiseling errors, the sawtooth of the depilatory saw blade is pre-rough-processed by laser, and the sawtooth is finely processed by a chiseling tool after cooling. A plurality of continuously distributed chiseling protrusions are arranged on the chiseling tool, and a plurality of sawteeth are chiseled at the same time to reduce processing errors such as missing teeth and half teeth, thereby improving processing accuracy and processing efficiency.

[0023] (2) Use laser for preliminary rough processing. On the one hand, due to the thermal deformation area caused by laser processing, especially near the tooth root, in order to reduce this area, laser processing is used to 2 / 3 of the tooth root, which reduces the difficulty of chiseling and improves processing efficiency. On the other hand, the sawtooth distribution position is calibrated through laser preliminary rough processing to determine the distribution position of each sawtooth, avoid missing teeth, half teeth and other processing problems, improve processing accuracy and reduce processing difficulty.

[0024] (3) After the initial chiseling process, when processing the next set of saw teeth, the position of the upper set of saw teeth is used for position calibration, and continuous processing is performed in an overlapping manner in sequence to reduce the positioning difficulty when processing different groups and improve the processing accuracy.

[0025] (4) A plurality of continuous chiseling protrusions are arranged on the chiseling tool, and a plurality of saw teeth are processed simultaneously by using the plurality of continuous chiseling protrusions, thereby reducing the cumulative error generated when processing a single saw tooth, ensuring the relative position between the plurality of saw teeth processed in the same group is accurate, and being suitable for the depilatory saw blade with a high saw tooth distribution density.

[0026] (5) The laser processing component and the chiseling tool are arranged at intervals to ensure that there is enough time for the saw blade to cool down after laser processing. The depilatory saw blade after laser processing is heated due to the thermal efficiency of the laser, and the subsequent cooling process is combined to achieve the effect of heat treatment. The role of the temperature regulating component is superimposed to achieve secondary heat treatment. Compared with the traditional processing method, the depilatory saw blade can be more wear-resistant. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] Example 1

[0033] In a typical embodiment of the present invention, Figure 1-Figure 3 As shown, a laser processing chiseling device for a lint stripping saw blade is provided.

[0034] like Figure 1 The laser processing chiseling device for the depilatory saw blade shown uses laser to perform rough processing of the teeth of the depilatory saw blade 7, selects a reasonable laser operation process to ensure sufficient time for cooling, and then uses the chiseling tool 2 that can process multiple teeth at the same time to perform fine processing on the rough-processed saw blade 7, thereby improving processing efficiency and ensuring processing accuracy.

[0035] like Figure 1 , Figure 3 The laser processing and chiseling device for a depilatory saw blade shown mainly comprises a laser assembly, a rotating support 13 and a chiseling tool 2, which are arranged at intervals and installed together on a base 5. The rotating support 13 is used to carry the depilatory saw blade 7 to be processed, the laser assembly can output laser to perform rough processing on the depilatory saw blade 7, and the chiseling tool 2 can perform fine chiseling on the depilatory saw blade 7 after rough processing.

[0036] A clamp is installed on the rotating support 13, and the clamp forms an annular clamping part for accommodating the stripping saw blade 7. The output end of the laser component faces the edge of the annular clamping part, which is used to calibrate the sawtooth position of the stripping saw blade 7 and perform rough processing.

[0037] The laser assembly includes a laser head 10, a support arm 1 and an adjustment seat 11 which are connected in sequence. The adjustment seat 11 is arranged at an interval with the rotating base 5. The adjustment seat 11 is connected to the laser head 10 through the support arm 1. The laser head 10 is suspended above the annular clamping part.

[0038] The laser head 10 corresponds to a complete laser system. The laser head 10 in this embodiment is the output end of the laser system. For the power supply, adjustment and other components of the matching laser head 10, existing mature equipment is used. At the same time, the corresponding laser head 10 should have an infrared device for positioning. Before processing, the processing position is projected by infrared to facilitate the positioning of the processing position.

[0039] The support arm 1 can be used as an adjustment bracket for the laser head 10, providing the laser head 10 with freedom of movement, realizing the rotation adjustment and orientation adjustment of the laser head 10, and ensuring the accurate positioning of the laser by the adjustment seat 11 combined with the support arm 1.

[0040] In addition, the laser head 10 is adjusted in its action position by rotating and moving the laser in different directions, so as to adapt to different processing positions of peeling saw blades 7 of different diameters, ensuring that saw blades 7 of different diameters can be processed. At the same time, the rotation effect during multi-angle laser processing can change its processing range to meet the different sawtooth sizes corresponding to peeling saw blades 7 of different diameters.

[0041] like Figure 1 As shown, after the laser assembly roughly processes the depilatory saw blade 7, the saw teeth are finely processed by the chiseling tool 2; the chiseling tool 2 is connected to the reciprocating motion mechanism 12 and is arranged on one side of the annular clamping part, the movement trajectory of the chiseling tool 2 is parallel to the axis of the annular clamping part, and the chiseling tool 2 is provided with continuously arranged chiseling protrusions that simultaneously cooperate with multiple saw teeth.

[0042] The shape and number of the chiseling protrusions provided on the chiseling tool 2 are determined according to the size and number of the depilatory saw blades 7 to be processed. The chiseling tool 2 squeezes and cuts the depilatory saw blades 7 so that the cutting position is consistent with the distribution shape of the chiseling protrusions on the chiseling tool 2. In this embodiment, the thickness of the chiseling tool 2 is generally about 10 mm, which is 10 times the thickness of the depilatory saw blade 7 to be processed, so as to provide sufficient wear resistance.

[0043] The chiseling protrusion of the chiseling tool 2 is made of cemented carbide or other alloy materials. During laser rough processing, there will be a thermal deformation area due to laser processing, especially near the tooth root. In order to reduce the influence of the thermal deformation area on the chiseling accuracy, in this embodiment, the laser component is used to process the sawtooth to 2 / 3 of the tooth root, and the sawtooth residue before reaching the target size is processed by the chiseling tool 2.

[0044] like Figure 2As shown, the chiseling tool 2 includes a chiseling tool and a tool holder 4, and a reciprocating mechanism 12 is connected to the tool holder 4 to drive the chiseling tool 2 to reciprocate. The tool holder 4 can be matched with chiseling tools of different specifications, and the chiseling tool is provided with a plurality of replaceable ones. The tool holder 4 can be detachably connected to the chiseling tool, and the chiseling protrusions on different chiseling tools have different specifications to adapt to saw teeth of different specifications.

[0045] In this embodiment, the connecting member 3 can adopt three spaced-apart pins or screws to stably mount the chisel cutter on the tool holder 4, and the tool holder 4 and the chisel cutter act together.

[0046] The tool holder 4 can increase the contact area with the chiseling cutter, provide good load-bearing stability for the chiseling cutter, and provide stable output during the chiseling process. The chiseling cutter 2 and the reciprocating motion mechanism 12 are used in conjunction with each other. The reciprocating motion mechanism 12 can be a reciprocating drive mechanism such as a cylinder or an electric cylinder. In this embodiment, a cylinder is used, which can respond quickly and increase the chiseling speed to reduce the deformation of the sawtooth position of the depilatory saw blade 7 during the chiseling process.

[0047] The reciprocating motion mechanism 12 provides the chiseling tool 2 with up and down motion, and performs reciprocating up and down motion during processing to cut the residual allowance of the saw tooth position of the depilatory saw blade 7 left after laser processing.

[0048] The tool holder 4 can adjust the height under the action of the reciprocating motion mechanism 12, and can also change the specifications of the matching chiseling cutter. The bottom surface of the tool holder 4 is connected to the output end of the cylinder, and the top surface of the tool holder 4 can position and connect the chiseling cutter.

[0049] The power element of the cylinder is installed in the base 5. At the same time, one end of the cylinder is also fixed on the base 5. The control element can be arranged in the base 5.

[0050] like Figure 1 , Figure 2 As shown, a temperature regulating assembly 14 is provided at the edge of the annular clamping portion. The temperature regulating assembly 14 includes an electromagnetic heating mechanism and a cooling mechanism. The temperature regulating mechanism is spaced apart from the chiseling tool 2 and is located at the same circumferential position of the annular clamping portion.

[0051] After laser rough processing, since the depilatory saw blade 7 is relatively thin, if reciprocating tooth-slotting processing is performed, the saw blade 7 will be bent and the surface will be uneven. Therefore, in this embodiment, after laser rough processing, the depilatory saw blade 7 is heated by an electromagnetic induction mechanism to raise the temperature of the depilatory saw blade 7 to 800°C-1000°C, and the tooth-slotting processing is performed after the forming performance of the depilatory saw blade 7 is improved. At this time, since the thickness of the chiseling tool 2 is much greater than the thickness of the depilatory saw blade 7, the depilatory saw blade 7 is easy to process under high temperature conditions, and the processing accuracy can be achieved after several reciprocating cycles. After that, the processing position of the depilatory saw blade 7 is cooled by a cooling mechanism, and the cooling can be air cooling, water cooling, oil cooling, etc. Quenching or tempering can be performed. By quenching or tempering the saw teeth separately, the strength of the saw teeth can be increased. At the same time, the toughness of other disc parts of the depilatory saw blade 7 is maintained to ensure that the depilatory saw blade 7 will not be brittle due to low toughness after quenching.

[0052] It can be understood that the temperature regulating component 14 includes an arc-shaped action plate 6, which adapts to the distribution shape of the continuous saw teeth in the area to be processed, improves the action accuracy, and reduces the impact on other non-processing areas. The action plate 6 forms an action surface on the side facing the stripping saw blade 7, and the electromagnetic heating mechanism and the cooling mechanism act on the stripping saw blade 7 through the action surface respectively to heat up or cool down the stripping saw blade 7.

[0053] like Figure 1 , Figure 3 As shown, the clamp includes a base plate and a pressure plate sleeved on the rotating shaft, an annular clamping portion is formed between the base plate and the pressure plate, and a fastener 9 is provided on the rotating shaft away from the side of the pressure plate to maintain the relative position of the base plate and the pressure plate.

[0054] The clamp can provide support and protection for the processing of the depilatory saw blade 7. Since the thickness of the depilatory saw blade 7 is generally 1 mm, the size is thin and the diameter is large, the deformation of the depilatory saw blade 7 can be avoided by the tight clamping effect of the bottom plate and the pressure plate of the clamp during the chiseling and laser processing. Especially during the chiseling process, the impact force is large, which can easily cause the saw blade 7 to bend. By arranging the depilatory saw blade 7 between the bottom plate and the pressure plate, the clamping force and the limit effect are provided from the top and bottom, and the thickness is 3-6 times that of the saw blade 7, the deformation during the processing is reduced.

[0055] The bottom plate and the pressure plate are both annular plates, which are coaxially sleeved on the rotating shaft and rotate synchronously with the rotating shaft. A plurality of radially distributed pressure rods are provided on the side of the pressure plate away from the bottom plate. The top of the pressure rod is circular arc-shaped to reduce scratches from sharp edges and effectively protect personnel safety.

[0056] The fastener 9 can clamp the top plate 8 and the bottom plate from the top and bottom surfaces of the depilatory saw blade 7 , and a threaded sleeve mechanism can be selected, and its size is determined according to the diameter of the central circular hole of the depilatory saw blade 7 .

[0057] The rotating support 13 drives the clamp and the stripping saw blade 7 to rotate a certain angle after each tooth chiseling process. A servo motor structure can be used to ensure that each rotation angle is as accurate as possible.

[0058] Example 2

[0059] In another typical embodiment of the present invention, Figure 1-Figure 3 As shown, a working method of a laser processing chiseling device for a lint stripping saw blade is provided.

[0060] Using the laser processing chiseling device of the depilatory saw blade in Example 1, the working method includes:

[0061] The depilatory saw blade 7 is clamped on the rotating support 13 by a clamp, and the laser assembly acts on the saw teeth to be processed for rough processing;

[0062] Rotate the depilatory saw blade 7 so that the saw teeth after rough processing correspond to the chiseling protrusions of the chiseling tool 2, and fix the position of the depilatory saw blade 7;

[0063] The chiseling tool 2 reciprocates to chisel the plurality of saw teeth after rough machining;

[0064] The depilatory saw blade 7 is rotated to process a corresponding group of multiple saw teeth through the chiseling tool 2, wherein the group of saw teeth includes at least one saw tooth processed in the previous group;

[0065] The depilatory saw blade 7 is rotated to perform rough processing and chiseling processing on all the saw teeth to be processed.

[0066] In addition, the laser component sets the number of teeth on the depilatory saw blade 7 and performs rough processing on all the teeth to be processed accordingly, and calibrates the working position of the chiseling tool 2 with the rough-processed teeth.

[0067] Specific, combined Figure 1-Figure 3 In combination with Embodiment 1, the top plate 8 and the bottom plate of the clamp are used to maintain the overall flatness of the depilatory saw blade 7 during the processing. The top plate 8 and the bottom plate are combined with the fastener 9 to make the depilatory saw blade 7 fit, so as to achieve stable tightening of the depilatory saw blade 7.

[0068] The infrared device in the laser assembly is first positioned to ensure the range of the number of teeth to be processed and the processing depth. When it is ensured that there are no missing teeth or broken teeth, the laser device is started. Cooperate with the support arm 1 and the laser head 10 to perform multi-angle rotation processing. In order to avoid the influence of thermal deformation, the path of laser processing needs to be set. The number of teeth of the depilatory saw blade 7 is an even number, and the teeth are generally processed to ensure that there is enough time for cooling. At the same time, due to the thermal effect of the laser, the saw teeth after laser processing can reduce secondary heat treatment, which is more wear-resistant than traditional processing.

[0069] When all teeth of the depilatory saw blade 7 are roughly processed, fine processing begins. At this time, the number of chiseling protrusions on the chiseling tool 2 is 1 / 4 or 1 / 6 of the total number of teeth of the depilatory saw blade 7, and the shape and specification of the chiseling protrusions should match the tooth shape of the depilatory saw blade 7 to be processed.

[0070] During processing, the depilatory saw blade 7 is first heated to a temperature that is convenient for processing, and the infrared device of the laser is used to assist in cooperation to ensure that the processing size meets the requirements. Then the chiseling tool 2 is raised or lowered to keep the rotating support 13 stable to avoid secondary damage caused by rotation.

[0071] After the chiseling is completed, the cooling mechanism is started and begins to spray coolant to quickly cool the teeth of the depilatory saw blade 7. After one processing is completed, the depilatory saw blade 7 is rotated and adjusted under the drive of the rotating support 13, and each tooth position is located by the infrared device. The above processing process is repeated and cycled in sequence until the depilatory saw blade 7 is removed after the processing is completed. A new round of processing is carried out after the workpiece is replaced.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
