Description

TECHNICAL FIELD

[0001] The application relates to the alloy steel processing technical field, in particular to an edge cutting device for alloy steel processing. BACKGROUND

[0002] The alloy steel is a metallic material prepared by adding alloy elements such as chromium, nickel, manganese and molybdenum on the basis of carbon steel, and the strength, hardness, corrosion resistance and high-temperature stability of the alloy steel are significantly improved compared with those of the carbon steel. The edge cutting device for alloy steel processing is a special edge cutting equipment suitable for the characteristics of the alloy steel. The device usually adopts high-strength cutting tools, integrates an adjustable pressure cutting assembly and a wear-resistant guide structure, and some devices adapt to different alloy steel hardnesses by optimizing cutting angles and feeding speeds, can accurately cut off the edge excess of the alloy steel workpiece and remove burrs, and guarantee subsequent machining precision. The edge cutting device is an important equipment in the alloy steel component manufacturing process.

[0003] In the prior art, the Chinese patent document with the publication number CN116652289A discloses a composite plate center positioning edge cutting device, which comprises edge cutting devices arranged on both sides of the composite plate. A centering detector is arranged at the middle position of the edge cutting devices on both sides of the composite plate. The centering detector is used for detecting the position of the alignment line on the lower surface of the composite plate. The application has the effect that the two sides of the copper-aluminum composite plate can be cut relatively uniformly.

[0004] In view of the above and the prior art, the inventors believe that the following defects often exist: in the alloy steel plate processing process, in order to ensure that the surface of the plate reaches the specified smoothness standard, the two sides of the plate need to be edge cut. During processing, the plate is clamped and positioned with the operating table through a fixed clamping mechanism. However, after the single-side edge cutting operation is completed, the plate needs to be turned or flipped over for processing on the other side. However, the existing clamping mechanism has functional limitations and cannot automatically complete the plate flipping action. It must rely on auxiliary devices for cooperation and operation. During the operation process, the clamping and fixing need to be released first, and then the clamping and positioning are performed again after the plate is flipped over. This not only increases the additional process, but also prolongs the single processing cycle, ultimately leading to a significant decrease in overall processing efficiency, which is difficult to meet the efficient production requirements.

DETAILED DESCRIPTION

[0019] It is easy to understand that, according to the technical solution of the present application, those skilled in the art can propose a variety of structural ways and implementation ways that can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary descriptions of the technical solution of the present application, and should not be considered as the whole or as a limitation or restriction on the technical solution of the present application.

[0020] Reference Figures 1 to 9 As shown in the figure, the present application provides a technical solution: an edge trimming device for alloy steel processing, comprising a workbench 1, the upper part of the workbench 1 is provided with a placement table 4, the upper part of both ends of the placement table 4 is provided with a conversion assembly 5, the outer surface of the conversion assembly 5 is provided with a clamping assembly 6, both ends of the placement table 4 are provided with a locking assembly 7, the side edge of the upper surface of the workbench 1 is provided with a guiding assembly 8, the side edge of the workbench 1 is provided with a translation mechanism 2, the upper surface of the translation mechanism 2 is movably provided with a trimming mechanism 3.

[0021] In the process of alloy steel plate processing edge cutting, the alloy steel plate to be cut is placed on the guide assembly 8, and the alloy steel plate is put into the clamping assembly 6 in a rolling manner, which is more labor-saving, and the alloy steel plate is clamped stably. Start the translation mechanism 2 and the edge cutting mechanism 3. The edge cutting mechanism 3 runs to cut the edge of the alloy steel plate, and moves along the workbench 1 under the drive of the translation mechanism 2, realizes the complete cutting of the edge of the alloy steel plate, and then the conversion assembly 5 runs to turn over the alloy steel plate, which is convenient for cutting the other side. The locking assembly 7 ensures that the alloy steel plate is in a horizontal stable state after turning over.

[0022] Referring to Figures 2 to 4 As shown in the figure, the conversion assembly 5 includes a vertical plate 51 fixedly connected to the upper surface of the placing table 4, a sliding block 52 slidingly limited in the middle of the vertical plate 51, a sleeve ring 54 movably inserted in the middle of the sliding block 52, a limiting strip 55 slidingly inserted in the inside of the sleeve ring 54, a cross plate 56 fixedly connected to the end of the limiting strip 55, a push plate 57 fixedly connected to the section away from the limiting strip 55 of the cross plate 56, a ratchet wheel 58 fixedly sleeved on the outer surface of the sleeve ring 54, a ratchet strip 59 provided on the outer surface of the vertical plate 51, a horizontal plate 510 rotatably connected to the end away from the cross plate 56 of the limiting strip 55, a lead screw 511 movably inserted into the outer surface of both ends of the horizontal plate 510, the lead screw 511 penetrating through the vertical plate 51 and being threadedly connected with the vertical plate 51, the lead screw 511 being rotatably connected with the horizontal plate 510, a hydraulic rod 53 provided on the top end of the vertical plate 51, the driving end of the hydraulic rod 53 being fixedly connected with the sliding block 52, the sleeve ring 54 being rotatably connected with the sliding block 52, the ratchet strip 59 being provided on the upper half of the vertical plate 51, and the number of teeth of the ratchet strip 59 being half of the number of teeth of the ratchet wheel 58.

[0023] The hydraulic rod 53 pulls the sliding block 52 to slide upward along the inside of the vertical plate 51, and after being separated from the locking assembly 7, the ratchet wheel 58 will engage with the ratchet strip 59. Due to the one-way engagement principle of the ratchet wheel 58 and the ratchet strip 59, during the upward movement of the ratchet wheel 58 along with the sliding block 52, the ratchet wheel 58 and the ratchet strip 59 are in a sliding state. When the ratchet wheel 58 moves to the top end of the ratchet strip 59, the hydraulic rod 53 pushes the sliding block 52 to move downward. At this time, under the limiting action of the ratchet strip 59, the ratchet wheel 58 will be turned over, which will drive the sleeve ring 54 and the limiting strip 55 to rotate synchronously. During the turning over of the limiting strip 55, the alloy steel plate will be turned over by 180 degrees synchronously. Without the need to disengage the clamping assembly 6, the alloy steel plate is automatically turned over, improving the efficiency of alloy steel plate processing.

[0024] Referring to Figures 4 to 6As shown, the clamping assembly 6 comprises a positioning rod 61 movably inserted into the outer surface of the push plate 57, the end of the positioning rod 61 is fixedly connected with an inner plate 62, the outer surface of the positioning rod 61 is sleeved with a compression spring 68, one end of the compression spring 68 is fixed on the end of the positioning rod 61, the other end is fixed on the outer surface of the push plate 57, the upper and lower sides of the inner plate 62 are provided with a wedge block 63, the outer surface of the wedge block 63 is fixedly connected with a clamping plate 65, the outer surface of the push plate 57 is provided with a sliding groove 64, the wedge block 63 is slidingly connected in the sliding groove 64, the outer surface of the wedge block 63 is provided with a slide 67, the upper and lower sides of the inner plate 62 are slidingly connected in the slide 67, and the outer surface of the clamping plate 65 is fixedly connected with a rubber strip 66.

[0025] When the workbench 1 is operated, the rotating screw rod 511 will drive the horizontal plate 510 to move towards the vertical plate 51, at the same time, the horizontal plate 510 will drive the limiting strip 55 to push the cross plate 56, and the operation of the two sides of the workbench 1 can drive the push plates 57 to move close to each other, so that the inner plate 62 abuts against the two ends of the alloy steel plate during the operation, and the continuous rotation will force the inner plate 62 to push the alloy steel plate, and under the reaction force, the inner plate 62 will move close to the push plate 57, thereby sliding the positioning rod 61 and stretching the compression spring 68, so that the compression spring 68 is deformed and stores elastic potential energy. In addition, the upper and lower sides of the inner plate 62 will slide along the slide 67 of the wedge block 63 during the movement of the inner plate 62, due to the inclined arrangement characteristics of the wedge block 63 and the sliding, the inner plate 62 will pull the wedge blocks 63 at both ends to move close to each other during the sliding, so that the wedge blocks 63 will slide along the sliding groove 64 and move to the middle part of the inner plate 62, at the same time, the wedge blocks 63 will drive the clamping plates 65 to move synchronously, and the clamping plates 65 distributed above and below will clamp the alloy steel plate in the middle part, at the same time, the two ends of the alloy steel plate are also clamped by the pushing of the inner plate 62, which improves the stability of clamping, and the rubber strips 66 are arranged on the contact surfaces between the clamping plates 65 and the alloy steel plate, which not only can increase the friction, but also can avoid the damage to the surface of the alloy steel plate caused by clamping.

[0026] Referring to Figure 2 and Figure 7 As shown, the locking assembly 7 comprises a support 71 fixedly connected to the side of the workbench 1, a round rod 72 movably inserted into the middle part of the support 71, the top end of the round rod 72 is fixedly connected with a clamping seat 73, the upper surface of the clamping seat 73 is provided with a clamping groove 74, the outer surface of the round rod 72 is sleeved with a butterfly spring 76, one end of the butterfly spring 76 abuts against the upper surface of the support 71, the other end abuts against the lower surface of the clamping seat 73, the upper and lower sides of the sleeve ring 54 are fixedly connected with an extension rod 75, the clamping groove 74 is arranged in U type with the bottom concave, and the extension rod 75 is slidingly connected in the clamping groove 74.

[0027] During the continuous downward movement of the slider 52, the extension rod 75 will slide into the clamping groove 74 at the upper part of the clamping seat 73. Since the upper part of the clamping groove 74 is designed in an arc shape, if the extension rod 75 is in a vertical state, it will be clamped into the bottom of the clamping groove 74, achieving the locking of the sleeve ring 54. If the extension rod 75 is slightly inclined due to excessive rotation of the sleeve ring 54, the extension rod 75 will touch the inner wall of the clamping groove 74, which will force it to reverse during the downward movement until the extension rod 75 is clamped into the bottom of the clamping groove 74. A round rod 72 is arranged at the bottom of the clamping seat 73, and a butterfly spring 76 is sleeved on the outer surface of the round rod 72, achieving elastic buffering. The locking assembly 7 is used to lock the conversion assembly 5, ensuring that the alloy steel plate is in a horizontal stable state after being flipped.

[0028] Referring to Figure 8 and Figure 9 As shown in the drawings, the guide assembly 8 comprises a base 81 fixedly connected to the upper surface of the workbench 1. The outer surface of the base 81 is rotatably connected with a shaft seat 82. The top end of the shaft seat 82 is fixedly connected with a table plate 83. The outer surface of the shaft seat 82 is provided with a torsional spring 87. One end of the torsional spring 87 is fixedly connected to the outer surface of the shaft seat 82, and the other end is fixedly connected to the outer surface of the base 81. The upper surface of the table plate 83 is provided with a grid 84 plate. The outer surface of the grid 84 plate is provided with a plurality of nodes 85. The middle part of the nodes 85 is movably inserted with a rolling ball 86. The nodes 85 wrap about one-half of the middle part of the rolling ball 86. The upper surface of the nodes 85 is flush with the upper surface of the table plate 83.

[0029] The alloy steel plate to be trimmed is placed on the guide assembly 8. By pressing the edge of the alloy steel plate, the shaft seat 82 is deflected around the base 81, and the torsional spring 87 is twisted and stores elastic potential energy. The deflection of the table plate 83 causes one side of the alloy steel plate to be inclined upward and the other side to be inclined downward. After the alloy steel plate is aligned with the clamping assembly 6, the alloy steel plate is pushed along the table plate 83 to the clamping assembly 6. The design of the rolling ball 86 converts the sliding friction between the alloy steel plate and the table plate 83 into rolling friction, greatly reducing the friction and facilitating the movement of the alloy steel plate.

[0030] Working principle: During the processing and trimming of alloy steel plates, the alloy steel plate to be trimmed is first placed on the guide assembly 8. By pressing the edge of the alloy steel plate, the bearing seat 82 can be rotated around the base 81, which in turn causes the torsion spring 87 to twist and store elastic potential energy. The platform 83 is then rotated, causing one side of the alloy steel plate to face upwards and the other side to face downwards. After the alloy steel plate is aligned with the clamping assembly 6, it is pushed along the platform 83 towards the clamping assembly 6. Since the upper cavity of the platform 83 is equipped with a grid 84, and each node 85 of the grid 84 is equipped with a ball 86, the alloy steel plate is held in place by the grid. The sliding friction between plates 83 is converted into rolling friction, greatly reducing the friction force and facilitating the movement of the alloy steel plate. After the alloy steel plate is placed between the two clamping plates 65, it leaves the table 83. Under the rotational force of the torsion spring 87, it drives the bearing 82 to rotate, thereby driving the table 83 to return to a horizontal state. At this time, rotating the lead screw 511 will drive the horizontal plate 510 to move towards the vertical plate 51. At the same time, the horizontal plate 510 will drive the limit bar 55 to push the cross plate 56. Simultaneous operation on both sides of the worktable 1 can drive the push plates 57 to move closer to each other. This continues until the inner plate 6... 2. The inner plate 62 pushes the alloy steel plate at both ends as it continues to rotate, forcing the inner plate 62 to push the alloy steel plate. Under the reaction force, the inner plate 62 moves closer to the push plate 57, which in turn pushes the positioning rod 61 to slide and stretches the compression spring 68, causing the compression spring 68 to deform and store elastic potential energy. In addition, during the movement of the inner plate 62, the upper and lower sides of the inner plate 62 slide along the slide rail 67 of the wedge block 63. Due to the inclined setting characteristics of the wedge block 63 and the sliding, the inner plate 62 will pull the wedge blocks 63 at both ends closer to each other during the sliding process. In this way, the wedge blocks 63 will slide along the slide groove 64 and move towards the middle of the inner plate 62. At the same time, the wedge blocks 63 will drive the clamping plate. The 65-axis synchronous movement, with the upper and lower distributed clamping plates 65 clamping the alloy steel plate in the middle, while the two ends of the alloy steel plate are also pushed and clamped by the inner plate 62, improving the stability of the clamping. In addition, rubber strips 66 are set on the contact surface between the clamping plates 65 and the alloy steel plate, which not only increases the friction but also avoids damage to the surface of the alloy steel plate caused by clamping. After the alloy steel plate is clamped and fixed, the translation mechanism 2 and the edge cutting mechanism 3 are started. The edge cutting mechanism 3 will cut the edge of the alloy steel plate. At the same time, driven by the translation mechanism 2, it will move along the worktable 1 to achieve complete cutting of the edge of the alloy steel plate. After cutting one side of the alloy steel plate, the edge cutting mechanism 3 first moves away from the alloy steel plate, and then the hydraulic rod 53 operates to pull the sliding block 52 to slide upward along the inside of the vertical plate 51. After being separated from the locking assembly 7, the ratchet wheel 58 will engage with the pawl strip 59. Due to the one-way engagement principle of the ratchet wheel 58 and the pawl strip 59, during the upward movement of the ratchet wheel 58 with the sliding block 52, the ratchet wheel 58 and the pawl strip 59 are in a sliding state. When the ratchet wheel 58 moves to the top end of the pawl strip 59, the hydraulic rod 53 pushes the sliding block 52 to move downward. At this time, under the limiting action of the pawl strip 59, the ratchet wheel 58 will be flipped, which will drive the sleeve ring 54 and the limiting strip 55 to rotate synchronously. Since the number of teeth of the pawl strip 59 is half of that of the ratchet wheel 58, the ratchet wheel 58 will rotate 180 degrees under the action of the pawl strip 59. The limiting strip 55 is connected with the push plate 57 through the cross plate 56, and the clamping assembly 6 inside the push plate 57 fixes the alloy steel plate, so the limiting strip 55 will flip the alloy steel plate by 180 degrees during the flipping process. Without the need to disengage the clamping assembly 6, the alloy steel plate is automatically flipped, improving the efficiency of alloy steel plate processing. During the continuous downward movement of the sliding block 52, the extension rod 75 will slide into the clamping groove 74 on the upper part of the clamping seat 73. Since the upper part of the clamping groove 74 is designed in an arc shape, if the extension rod 75 is in a vertical state, it will be clamped into the bottom of the clamping groove 74, achieving the locking of the sleeve ring 54. If the extension rod 75 slightly tilts due to excessive rotation of the sleeve ring 54, the extension rod 75 will touch the inner wall of the clamping groove 74, forcing it to flip in the opposite direction during the downward movement until the extension rod 75 is clamped into the bottom of the clamping groove 74. A round rod 72 is arranged at the bottom of the clamping seat 73, and a butterfly spring 76 is sleeved on the outer surface of the round rod 72, achieving elastic buffering, and the rebound amplitude of the butterfly spring 76 is relatively low, so it will not rebound greatly during the upward movement of the conversion assembly 5. Combined with the limited ratchet wheel 58, it ensures that the extension rod 75 is in the clamping groove 74 when the ratchet wheel 58 encounters the pawl strip 59, achieving limiting. When the conversion assembly 5 moves downward, the ratchet wheel 58 moves to the bottom of the pawl strip 59, and the extension rod 75 is in a downward inclined position and has slid into the inner range of the clamping groove 74. Combined with the buffering of the butterfly spring 76, the clamping seat 73 is pushed downward, giving the extension rod 75 enough time and space to complete the clamping. The locking assembly 7 is used to lock the conversion assembly 5, ensuring that the alloy steel plate is in a horizontal stable state after flipping. Finally, the edge cutting mechanism 3 cuts the edges of the flipped alloy steel plate, thus completing the cutting of the edges of the alloy steel plate on both sides. Reverse rotation of the lead screws 511 at both ends forces the clamping plate 65 and the inner plate 62 to move away from the alloy steel plate, and the processed alloy steel plate is taken out. The alloy steel plate to be processed is loaded for reciprocating processing.

[0031] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should all belong to the protection scope of the present application.
