Description

Technical Field

[0001] This application relates to the technical field of processing equipment, in particular to an end plate groove processing system and a working method thereof. Background Art

[0002] ‌The flange end plate‌ is a connecting component used at the end of a flange. It is usually made of a square steel plate with a hole in the middle for easy connection with other components. The grooves of the end plate are cut at the four corners of the end plate, which are usually provided for the purposes of facilitating welding, improving welding quality, and facilitating handling, etc.

[0003] When the required precision for processing the groove is not strict, it can be processed by cutting or planing processes. In the existing end plate groove production line, since the four corners involved in the upper and lower bottom surfaces of the end plate need to be planed out, the processing method adopted by the existing process is usually to plane each side one by one, which makes the planing process take a long time and affects the smooth operation of the production line to a certain extent. Summary of the Invention

[0004] The purpose of this application is to provide an end plate groove processing system and a working method thereof.

[0005] To achieve the above object, the technical solution adopted in this application is as follows: An end plate groove processing system includes a conveying mechanism, a pushing mechanism, a first planing mechanism, a second planing mechanism, and a blanking mechanism. The first planing mechanism and the second planing mechanism are arranged perpendicular to each other, and the ends of the planing trajectories of the first planing mechanism and the second planing mechanism are connected to form an L-shaped configuration. When the pushing mechanism pushes the workpiece located at the first planing mechanism to the maximum stroke, the workpiece does not reach within the planing trajectory of the second planing mechanism. After several workpieces processed by the first planing mechanism are arranged in sequence, the next workpiece processed by the first planing mechanism pushes the frontmost workpiece into the planing trajectory of the second planing mechanism. Subsequently, the pushing mechanism pushes this workpiece to be processed by the second planing mechanism and finally transfers it to the blanking mechanism for blanking.

[0006] Preferably, both the first planing mechanism and the second planing mechanism plane the workpiece to cut out the groove through multiple planings, and the depths of the multiple planings are the same or decrease successively. The first planing mechanism and the second planing mechanism respectively form guide rails at their two planing trajectories. The end of the guide rail at the first planing mechanism extends to the initial end of the guide rail at the second planing mechanism to form an L-shaped configuration.

[0007] As a preference, the planing mechanism includes two symmetrically arranged planing cutter groups, and the two planing cutter groups are respectively used for planing the opposite sides of the workpiece; the same planing cutter group includes a plurality of planing blades arranged at intervals, and a planing spacing is formed between two adjacent planing blades. The depths of all the planing blades in the same planing cutter group increase sequentially along the planing forward direction to a set planing length.

[0008] As a preference, the planing cutter groups on both sides are hingedly installed and can be translated as a whole. The planing cutter group is provided with a corresponding fixing structure, and the planing angle is changed by rotating the planing cutter group during installation; a plurality of the planing spacings are generated between the multiple planing blades in the same planing cutter group and decrease sequentially along the planing forward direction; the increment of the multiple planing blades in the same planing cutter group in the planing depth direction decreases sequentially along the planing forward direction.

[0009] As a preference, the conveying mechanism includes a conveyor belt and a feeding structure. The feeding structure includes a grasping part and a transverse moving part. The transverse moving part drives the grasping part to move, and the grasping part grasps the workpiece so as to transfer the workpiece to the planing trajectory entrance of the first planing mechanism.

[0010] As a preference, the end plate groove processing system further includes an automatic blanking assembly. The automatic blanking assembly includes a grasping and feeding plate with a lifting function, a transverse moving component acting on the grasping and feeding plate, and a liftable blanking stacking table. After each workpiece is stacked on the blanking stacking table, the blanking stacking table descends a set distance so that the top surface of the uppermost workpiece stacked on the blanking stacking table is always at the same height as or below the bottom surface of the workpiece grasped by the grasping and feeding plate when it returns to the initial state after grasping the workpiece.

[0011] As a preference, an electrically controlled lifting structure and a pressure sensor are arranged at the bottom of the blanking stacking table. When the number of workpieces stacked on the blanking stacking table increases, the pressure sensor senses the increase in weight, so that the electrically controlled lifting structure automatically descends a set distance; when the number of workpieces stacked on the blanking stacking table decreases, the pressure sensor senses the decrease in weight, so that the electrically controlled lifting structure automatically rises a set distance.

[0012] As a preference, the blanking stacking table is provided with a guiding structure and an elastic supporting structure. When the number of workpieces stacked on the blanking stacking table increases, the elastic supporting structure descends a set distance under the action of the increased gravity of the workpieces, so that the top surface height of the uppermost workpiece on the blanking stacking table descends a set distance; when the number of workpieces stacked on the blanking stacking table decreases, the elastic supporting structure automatically rises a set distance under the action of the reduced gravity, so that the top surface height of the uppermost workpiece on the blanking stacking table rises a set distance.

[0013] As an optimization, the end plate bevel processing system further includes a loading and centering structure, which includes a slidably arranged first limiting part, a second limiting part arranged at the end of the conveying mechanism, and a third limiting part arranged on the side of the end of the conveying mechanism facing the planing mechanism. When the workpiece is conveyed to the end by the conveying mechanism, it abuts against the second limiting part and is aligned. Subsequently, the first limiting part slides to move the workpiece towards the third limiting part and finally abuts, so that the workpiece remains in a fixed position before loading.

[0014] On the other hand, the present application proposes a working method for end plate bevel processing, which includes the above-mentioned end plate bevel processing system and further includes the following steps;

[0015] a. Preliminary loading of the workpiece; during preliminary loading, the side of the workpiece is made parallel to the planing direction of the planing equipment and finally stops at the initial end of the planing trajectory of the planing equipment;

[0016] b. Further loading of the workpiece: Set a pusher device to perform parallel pushing from the initial end of the planing trajectory of the planing equipment, so that the workpiece advances in a suitable moving direction and finally passes through the planing equipment;

[0017] c. Planing treatment: The planing equipment planes out a triangular prism-shaped bevel at the four corners and edges of the workpiece, and the cut-away part has a triangular cross-section as a whole. The blades of the planing equipment are parallel to the bevel, starting from the edges at the four corners of the workpiece towards the bevel. The greater the depth, the gradually increasing the thickness of the cut-away part. The planing equipment performs multiple planings by setting multiple spaced blades. The thickness of the waste material cut by the multiple planing blades along the planing direction decreases in turn. Each planing removes a part to reduce the wear of the planing blades. According to the increasing thickness of the planing waste material, the planing depth is gradually reduced. At the same time, the intervals between the multiple planing blades along the planing direction decrease in turn. The first few planing blades cut a larger thickness, with less waste material curling and larger occupied space. The larger set intervals reduce waste material accumulation. The subsequent planing blades cut a smaller thickness, with more waste material curling and smaller occupied space. The smaller set intervals are sufficient for waste material removal.

[0018] Compared with the prior art, the beneficial effects of the present application are as follows:

[0019] The required pushing stroke of the pusher mechanism can be greatly reduced, and at the same time, the pusher mechanism can return in time for the processing of the next workpiece. When the pusher mechanism reaches its maximum stroke, the length between the pusher mechanism and the entrance of the planing trajectory of the second planing mechanism can be set to an integer multiple of the length of the workpiece. In this way, after each complete pushing by the pusher mechanism, exactly one workpiece is pushed into the planing trajectory of the second planing mechanism, thus ensuring the smooth operation of the entire system.

[0020] Through the adjustment settings of the planing depth and the planing spacing, increasing the planing depth successively along the planing direction and with the increasing amount decreasing successively can play a certain role in calibrating the wear of the blades in the same group, making the wear rates of the planing blades in the same group similar, so that when replacing, the remaining blades can be replaced together; on the other hand, through the adjustment of the planing spacing, decreasing successively along the planing direction can ensure the better discharge of the planing waste.

[0037] Embodiment:

[0038] Refer to Figures 1 to 11 , this embodiment proposes an end plate groove processing system, including a conveying mechanism 1, a pusher mechanism 3, a first planing mechanism 4, a second planing mechanism 5, and a blanking mechanism 6. The first planing mechanism and the second planing mechanism 5 are arranged perpendicular to each other, and the ends of the planing trajectories of the first planing mechanism and the second planing mechanism 5 are joined to form an L-shaped configuration. When the pusher mechanism 3 pushes the workpiece 7 located at the first planing mechanism 4 to the maximum stroke, the workpiece 7 does not reach within the planing trajectory of the second planing mechanism 5. After several workpieces 7 processed by the first planing mechanism 4 are arranged in sequence, the next workpiece 7 processed by the first planing mechanism 4 pushes the workpiece 7 at the frontmost position into the planing trajectory of the second planing mechanism 5. Subsequently, the pusher mechanism pushes this workpiece 7 to be processed by the second planing mechanism 5, and finally transfers it to the blanking mechanism 6 for blanking.

[0039] In this embodiment, the conveying mechanism 1 is used to orderly convey materials. Common existing conveying mechanisms 1 include chain wheel conveying or conveyor belts.

[0040] In this embodiment, the pusher mechanism 3 is a commonly used device for horizontally pushing materials. Common examples include air cylinders and screw sliders. Through simple modification and adding a suitable pusher head 19 (see Figure 8 ), it can be used to push the workpiece 7 in this embodiment.

[0041] The planing mechanism in this embodiment refers to a planing device that cuts the surface of the workpiece 7 with a blade, so as to form a relatively smooth surface on the surface of the workpiece 7.

[0042] End plates are commonly used at flange end covers. The common shapes are square or rectangular. During processing, holes are drilled in the middle. Many end plates have their tips cut off at the corners, which makes subsequent welding more convenient, improves welding quality, and can also prevent the corners from being too sharp. At the same time, after cutting the groove, the end plate is easier to be grasped and used. The planing device is a mechanical device commonly used for processing the corners of end plates. Its structure is simple and can meet the usage requirements because such cutting usually does not require high precision. The specific structure of the end plate used for illustration in this embodiment can be referred to Figure 1 .

[0043] In this embodiment, the planing operation is carried out by the planing device. Different from common planing devices, this device is usually used for production on an assembly line. Therefore, the planing device is usually located in a relatively fixed area and position. Moreover, in order to ensure relative consistency after processing the same batch of products, the planing device is usually adjusted to the set position before use and will not move anymore, which limits its use to a certain extent. Obviously, the planed part at the corner is usually not too thin, because when the cutting is thin, the formed groove has little impact on welding. For this reason, in this embodiment, both the first planing mechanism 4 and the second planing mechanism 5 perform multiple planings on the workpiece 7 to cut out the groove, and the depths of the multiple planings are the same or decrease in sequence. The first planing mechanism 4 and the second planing mechanism 5 respectively form a guide track at their respective two planing tracks. The end of the guide track at the first planing mechanism 4 extends to the initial end of the guide track at the second planing mechanism 5 to form an L-shaped configuration.

[0044] For the convenience of pipeline production, the end plate is subjected to two rounds of planing by a first planing mechanism 4 and a second planing mechanism 5 which are arranged perpendicular to each other, so as to produce a suitable bevel at the corners of the end plate. And the two planing mechanisms need to enable the workpiece 7 to move between them. Obviously, during pipeline production, the workpiece 7 generally enters and exits the planing mechanism by translation. Therefore, during the process from the start to the departure of the workpiece 7 for both the first planing mechanism 4 and the second planing mechanism 5, the route that the workpiece 7 passes through is called the planing trajectory. After the workpiece 7 is processed by the first planing mechanism 4, it transfers to the entrance of the planing trajectory of the second planing mechanism 5. Therefore, it can be understood that the planing trajectories of the first planing mechanism 4 and the second planing mechanism 5 are connected and form an L-shaped configuration. For specific reference, Figure 8 as shown in the arrow direction. The arrow direction shows the L-shaped trajectory and also shows the moving direction of the workpiece 7. To ensure the stability of the workpiece 7 during movement, obviously, guide rails can be set at the planing trajectory to limit the workpiece 7. Of course, Figure 8 at the planing trajectory shown, a rectangular groove is formed at both of its two positions. The workpiece 7 is located in the groove for sliding. During planing, it mainly acts on the corners. Therefore, the edge of the workpiece 7 can be completely fitted with the edge of the groove (of course, not absolutely fitted), which can ensure that the direction of the workpiece 7 remains stable during movement, that is, it moves towards the groove, which is the planing trajectory.

[0045] So when this processing system is working, the workpiece 7 moves on the L-shaped planing track by the pushing mechanism 3. If the pushing mechanism 3 directly pushes the workpiece through the first planing mechanism 4 and then continues to push it to the entrance of the planing track of the second planing mechanism 5, on the one hand, the stroke requirement of the pushing mechanism 3 is too long, and on the other hand, during this process, the first planing mechanism 4 is in an unworking state. Therefore, this is not the best implementation method. For this reason, another preferred implementation method is proposed: the pushing mechanism 3 does not have to directly push the workpiece 7 to the second planing mechanism 5. When the pushing mechanism 3 completes its pushing stroke, there is still a certain distance between the workpiece 7 and the entrance of the planing trajectory of the second planing mechanism 5. At this time, the pushing mechanism 3 returns and pushes the next workpiece 7 through the first planing mechanism 4 and then continues to push until the two workpieces 7 are in contact. At this time, the latter workpiece 7 pushes the former workpiece 7 forward by the distance of one workpiece 7. When circulating like this, obviously, the required pushing stroke of the pushing mechanism 3 can be greatly reduced, and at the same time, the pushing mechanism 3 can return in time to process the next workpiece 7. Further, to ensure the smooth processing of the workpiece 7, when the pushing mechanism 3 reaches its maximum stroke, the length between the pushing mechanism 3 and the entrance of the planing trajectory of the second planing mechanism 5 can be set to an integer multiple of the length of the workpiece 7. In this way, every time the pushing mechanism 3 completes a complete push, exactly one workpiece 7 is pushed into the planing trajectory of the second planing mechanism 5, thus ensuring the smooth operation of the entire system.

[0046] The planing mechanism includes two symmetrically arranged planing cutter groups, which are respectively used to plane the opposite sides of the workpiece 7; the same planing cutter group includes several planing blades arranged at intervals, and a planing spacing is formed between two adjacent planing blades. The depths of all the planing blades in the same planing cutter group increase sequentially along the planing forward direction to the set planing length. As Figure 6 , Figure 7 shown, Figure 6 The shown planing blade includes a first planing blade 16 and a second planing blade 17. In fact, we only look at the first planing blade 16. Based on the understanding of the setting of the first planing blade 16, the second planing blade 17 can be inferred. The following mainly discusses the setting and specific working principle of the first planing blade 16.

[0047] As Figure 6 is the corresponding view of the first planing mechanism 4. There is a dotted line below the first planing blade 16, which reflects the height conditions of the bottoms of three first planing blades 16 arranged at intervals among different first planing blades 16. Figure 6 From left to right in it is the planing direction of the workpiece 7. It can be seen that the leftmost first planing blade 16 protrudes the least, and at this time the corresponding depth of planing and contacting the workpiece 7 is also smaller. The middle first planing blade 16 is slightly lower, so the corresponding planing depth of this workpiece 7 increases. The rightmost first planing blade 16 has the largest depth, so the corresponding planing depth continues to increase. And the cutting schematic of the workpiece 7 can be referred to Figure 7 , Figure 7 In it, d1 is the schematic of the cutting depth of the leftmost first planing blade 16, d2 is the schematic of the cutting of the middle first planing blade 16, and d3 is the schematic of the cutting of the rightmost first planing blade 16. If the planing blade directly planes at the depth of d3, due to the large depth, the reaction force on the blade is large, so the blade is easy to be damaged. After multiple planings, the damage of the blade can be effectively reduced.

[0048] Of course, when the end plate is placed horizontally, all four corners of its upper side and lower side need to be planed. Therefore, as Figure 6 shown, the second planing blade 17 is used to plane the two corners of the lower side of the end plate (or the workpiece). It can be seen from left to right that a total of 4 second planing blades 17 are provided. The protruding distances of the first three increase gradually, and the protruding distance of the fourth is the same as that of the third. The fourth second planing blade 17 can be regarded as secondary processing of the end plate to ensure the planing quality of the bottom of the end plate.

[0049] On the other hand, if the values of d1, d2, and d3 mentioned above are the same, it can be seen that the part removed by the groove machining is a triangular prism bar. Correspondingly, the part actually removed by the blade of d1 will be the least. Therefore, for the first planing blade 16 on the left, its wear rate will be significantly less than that of the subsequent blades, which will cause problems when replacing the grinding blades, as it is inconvenient to handle due to the different wear degrees of different blades. Of course, this solution can be implemented, but it is not the most optimal solution. In fact, referring to Figure 7 as shown, d1, d2, and d3 gradually decrease. Because we can continue to refer to Figure 7 the gradually increasing s1, s2, and s3 in. In fact, generally speaking, the greater the removed part, the greater the reaction force. Therefore, considering comprehensively, setting d1, d2, and d3 to gradually decrease can play a certain role in calibrating the wear of the three, making the wear rates of the three first planing blades 16 corresponding to d1, d2, and d3 similar, so that the remaining blades can be replaced together when replacing.

[0050] In addition, since the above-mentioned d1, d2, and d3 gradually decrease, during corresponding cutting, the waste materials corresponding to d1, d2, and d3 in the removed waste materials become thinner and thinner. When metal cutting, thinner cutting will make the cutting waste curl more completely, so that the waste materials after cutting occupy less space and are easy to discharge. While the thicker the waste material, the less obvious the curling, so the occupied area will slightly increase. Therefore, the spacing of the three cutting blades as shown in Figure 6 can be set differently according to the cutting thickness. Since d1 > d2 > d3, the planing spacing will correspondingly become smaller and smaller, which is convenient for discharging waste materials.

[0051] The following gives the specific installation scheme of the planing tool group. As shown in Figure 5 and Figure 6 as shown, the planing tool groups on both sides are hinged and can be translated as a whole. The planing tool group is provided with corresponding fixing structures. During installation, the planing tool group is rotated to change the planing angle; multiple planing spacings are generated between multiple planing blades in the same planing tool group and gradually decrease along the planing forward direction (corresponding to the removal of the above-mentioned waste materials); the increase amounts of multiple planing blades in the same planing tool group in the planing depth direction gradually decrease along the planing forward direction (that is, d3 < d2 < d1). Figure 6 The three first planing blades 16 shown in are combined into a group, and a hinge shaft structure is arranged in the planing seat 18. Obviously, the groove of the planing seat 18 for accommodating the planing tool group is a long groove, which can be used for the planing tool group to perform small-angle rotation adjustment. The planing seat 18 is integrally detachably installed and can be adjusted for front-back translation.

[0052] As shown in Figure 1 and Figure 2 and Figure 9As shown, the preferred conveying mechanism 1 includes a conveyor belt and a loading structure 2. The loading structure 2 includes a grasping part 9 and a transverse movement part. The transverse movement part drives the grasping part 9 to move and grasp the workpiece, so as to transfer the workpiece 7 to the entrance of the planing track of the first planing mechanism 4. The transverse movement part can be set as a common translation drive structure such as a cylinder or a lead screw slide table, and its principle is easy to understand and will not be elaborated here. Of course, the grasping part 9 can also be provided with a lifting part such as a cylinder to realize its lifting function.

[0053] Furthermore, the end plate groove processing system further includes a loading centering structure. The loading centering structure includes a first limiting part 22 slidably arranged, a second limiting part 21 arranged at the end of the conveying mechanism 1 (here it is the end of the conveyor belt), and a third limiting part 20 arranged on the side of the end of the conveying mechanism 1 facing the planing mechanism. When the workpiece 7 is conveyed to the end by the conveying mechanism 1, it abuts against the second limiting part 21 and is corrected. Subsequently, the first limiting part 22 slides to make the workpiece 7 move towards the third limiting part 20 and finally abut against it, so that the workpiece 7 is kept in a fixed position before loading. The conveyor belt can convey the object to the end position as shown in Figure 9 As shown. When the workpiece 7 moves, the workpiece 7 with an inclined orientation will rotate to abut against and align with the second limiting part 21, so it can be corrected. At this time, the first driving part moves towards the third limiting part 20, and the first driving part pushes the workpiece 7 to abut against the third limiting part 20. At this time, it can be ensured that the workpiece 7 is aligned with the third limiting part 20. Through the above processing, it can be ensured that each workpiece 7 can be guaranteed to be in this final position when it is conveyed. Therefore, the grasping part 9 can grasp the workpiece 7 at a fixed position and can ensure the correct orientation of the workpiece 7. Subsequently, the transverse movement part drives the grasping part 9 to move to the entrance of the planing track of the first planing mechanism 4 and corresponds to the pusher mechanism 3. Subsequently, the pusher mechanism 3 pushes the workpiece 7 for subsequent processing.

[0054] The above-mentioned loading centering structure and the loading structure 2 can realize the oriented loading of the workpiece 7, and the whole process does not require complex electric control or manual processing.

[0055] As Figure 1 、 Figure 2 and Figure 11As shown in the figure, the local end plate groove processing system further includes an automatic blanking assembly 8. The automatic blanking assembly 8 includes a gripping plate 12 with a lifting function, a transverse movement member acting on the gripping plate 12, and a liftable blanking stacking table 11. After each workpiece 7 is stacked on the blanking stacking table 11, the blanking stacking table 11 descends a set distance, so that the top surface of the uppermost workpiece 7 stacked on the blanking stacking table 11 is always at the same height or below the bottom surface of the workpiece 7 grabbed by the gripping plate 12 when it returns to the initial state after grabbing the workpiece 7. In this embodiment, through the automatic lifting of the blanking stacking table 11, it can be ensured that when the workpieces 7 are stacked, after increasing or decreasing the workpieces 7, the blanking stacking table 11 always remains in a relatively fixed position. In this way, when the gripping plate 12 grabs the workpiece 7 and transfers it to the blanking stacking table 11, stacking blanking can be carried out relatively accurately. When lifting, the gripping plate 12 refers to Figure 3 , its top can be driven to lift by setting a gripping cylinder 14. The piston rod at the bottom of the gripping cylinder 14 can be connected to the gripping plate 12 by setting a movable block 13, and an electromagnet can be set at the bottom of the gripping plate 12 to grab. Although the top of the gripping plate 12 can be provided with a gripping cylinder 14 for lifting, due to the stacking of the workpieces 7, when the height of the workpieces stacked on the top of the blanking stacking table 11 increases to a certain extent, when the gripping cylinder 14 rises to the top, it is no longer possible to continue stacking materials.

[0056] The following presents two preferred implementation schemes for the automatic lifting of the blanking stacking table 11.

[0057] (1) An electrically controlled lifting structure and a pressure sensor are provided at the bottom of the blanking stacking table 11. When the stacking quantity of the workpieces 7 on the blanking stacking table 11 increases, the pressure sensor senses the increased weight, so that the electrically controlled lifting structure automatically descends a set distance; when the stacking quantity of the workpieces 7 on the blanking stacking table 11 decreases, the pressure sensor senses the decreased weight, so that the electrically controlled lifting structure automatically rises a set distance (here, the electrically controlled lifting structure can be the Figure 3 , Figure 11 shown lifting cylinder 10). In this embodiment, the sensor can also be set as other sensor types such as a vision sensor. The principle of the sensor identifying the height of the top workpiece 7 is relatively simple, so this solution will not be described in detail.

[0058] (2) The blanking stacking table 11 is provided with a guiding structure and an elastic supporting structure. When the stacking quantity of the blanking parts 7 on the blanking stacking table 11 increases, the elastic supporting structure descends a set distance under the action of the gravity of the increased parts 7, so that the top surface height of the uppermost part 7 on the blanking stacking table 11 descends a set distance; when the stacking quantity of the blanking parts 7 on the blanking stacking table 11 decreases, the elastic supporting structure automatically rises a set distance under the action of the reduced gravity, so that the top surface height of the uppermost part 7 on the blanking stacking table 11 rises a set distance. The above elastic supporting structure can be a spring. In the initial position, there are no blanking parts 7 stacked on the blanking stacking table 11. At this time, the spring descends to the initial position under the gravity of the blanking stacking table 11. When the parts 7 are increased at this time, the spring will descend when the force on the spring increases, and the spring will reset after the parts 7 are taken away. Therefore, only a spring with an appropriate elastic coefficient needs to be selected to achieve this. After the spring is used for a long time, its performance changes, but the influence is small. In fact, the positions of the blanking stacking tables 11 do not need to be exactly the same, as long as they are generally the same. When the gripping plate 12 grips and places the part 7, there can be a certain gap between the gripping plate 12 and the uppermost part 7 on the blanking stacking table 11.

[0059] On the other hand, the present application proposes a working method for end plate groove processing, based on the above end plate groove processing system, including the following steps:

[0060] a. Preliminary feeding of the part 7: When feeding preliminarily, make the side surface of the part 7 parallel to the planing direction of the planing equipment and finally stop at the initial end of the planing track of the planing equipment; this step can be realized by the conveying mechanism 1, the feeding structure 2, the feeding centering structure, the pushing mechanism 3, the first planing mechanism 4 and the second planing mechanism 5.

[0061] b. Further feeding of the part 7: Set the pushing equipment to start parallel pushing from the initial end of the planing track of the planing equipment, so that the part 7 advances in a suitable moving direction and finally passes through the planing equipment; this step can be realized by the cooperation of the pushing mechanism 3 with the first planing mechanism 4 and the second planing mechanism 5.

[0062] c. Planing treatment: The planing equipment planes a triangular prism-shaped groove at the four corners and edges of the workpiece 7. The overall cross-section removed is triangular. The blades of the planing equipment are parallel to the groove. Starting from the edges at the four corners of the workpiece 7 and moving towards the groove, the depth increases and the thickness removed also gradually increases. The planing equipment performs multiple planings by setting multiple spaced blades. The thickness of the waste removed by multiple planing blades along the planing direction decreases in sequence. Each planing removes a part to reduce the wear of the planing blades. The planing depth is reduced successively according to the increase in the thickness of the planing waste. At the same time, the intervals between multiple planing blades along the planing direction decrease in sequence. The first few planing blades remove a larger thickness. The waste has a small amount of curling and occupies a large space. The larger set intervals reduce the waste accumulation. The subsequent planing blades remove a small thickness. The waste has a large amount of curling and occupies a small space. The smaller set intervals are sufficient for waste removal. This step is achieved by the first planing mechanism 4 and the second planing mechanism 5.
