Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a discharge turning die and a punching assembly. Background Art

[0002] The processing of profiles is generally divided into loading, cutting, punching and unloading. In order to improve the processing efficiency of profiles, a conveyor belt can be used to connect the various processing equipment according to the processing sequence to realize production line production.

[0003] After cutting, the profile forms a plurality of rectangular tubes. The existing automatic punching equipment generally only punches the wide side of the rectangular tube. For example, the "Punching Assembly and Profile Processing Line Including the Same" with publication number CN219786229U, although the prior art can automatically punch the wide sides of a plurality of rectangular tubes at the same time, but for the punching of the narrow side of the rectangular tube, it is easy to fall over due to insufficient stability during transportation. Therefore, punching can only be performed by manual die alignment at present, and the processing efficiency is extremely low.

[0004] After technological iteration, there are now automated punching equipment that can realize automatic punching of the narrow side of rectangular tubes, such as the "Punching Assembly and Profile Processing Line" with publication number CN118122875A, which uses a hanging part to provide overhead support for both ends of the rectangular tube, so that the rectangular tube can be flipped from a horizontal state to a vertical state under gravity deflection.

[0005] Although the above structure can theoretically flip the rectangular tube from a horizontal state to a vertical state, so that the rectangular tube can be transported with its wide side and punched with its narrow side, when facing multiple rectangular tubes with similar length-to-width ratios, when the hanging part extends into the opening of the rectangular tube, the eccentricity of the rectangular tube is not enough to overcome the friction between two adjacent rectangular tubes, so the rectangular tube cannot flip from a horizontal state to a vertical state autonomously, and then interferes with the mold core, eventually causing punching failure. Utility Model Content

[0006] The utility model aims to provide a discharge turning die to eliminate the friction between two adjacent rectangular tubes.

[0007] According to the first aspect of the present invention, the discharge turning mold comprises:

[0008] Next template;

[0009] There are multiple mold cores, and the multiple mold cores are all arranged on the lower mold plate. The multiple mold cores are arranged at intervals along the first straight line direction. Each of the mold cores has a first outer end face, and each of the first outer end faces is provided with a rotary guide head. At least one of the rotary guide heads is provided with a first guide slope for separating and discharging.

[0010] According to the discharge turning mold of the embodiment of the utility model, at least the following beneficial effects are achieved: during processing, the two discharge turning molds are respectively located on both sides of a plurality of rectangular tubes; when all the rectangular tubes reach the designated position and are lifted, the two discharge turning molds move toward the direction close to the rectangular tubes; each two rotary guide heads respectively extend into the inner cavity of a rectangular tube; at this time, the moving path of the first guide slope intersects with the inner wall of the rectangular tube; during this process, the inner wall of the rectangular tube contacts the first guide slopes of the corresponding two rotary guide heads; as the two rotary guide heads gradually go deeper, the two rotary guide heads force the rectangular tube to move along the two first guide slopes, thereby realizing the separation of two adjacent rectangular tubes; when each two adjacent rectangular tubes are separated by the rotary guide heads, all the rectangular tubes are in a separated discharge state, thereby eliminating the friction between the two adjacent rectangular tubes, so that all the rectangular tubes can autonomously flip from a horizontal state to a vertical state in the subsequent flipping process, thereby avoiding punching failure.

[0011] According to some embodiments of the present invention, the projection of the rotary guide on the first outer end surface is within the size range of the first outer end surface. Since the outer size of the mold core just matches the inner size of the rectangular tube, once the rotary guide exceeds the first outer end surface, interference will occur.

[0012] According to some embodiments of the present invention, since the rotary guide head needs to have a function of guiding rotation in addition to a guiding function, all rotary guide heads include a head in the shape of a cone or a truncated cone.

[0013] According to some embodiments of the utility model, all mold cores are provided with a second guiding slope connected to the first outer end surface, and the height of the second guiding slope gradually increases from the first outer end surface. When the two mold cores gradually extend into the two side openings of the rectangular tube, the two ends of the rectangular tube can be respectively positioned and supported outside the two mold cores through the corresponding second guiding slopes, thereby fixing the position of the rectangular tube.

[0014] According to some embodiments of the utility model, in order to punch a rectangular tube, a die hole is provided on the upper end surface of each die core, and the die hole penetrates the die core so as to discharge punching waste.

[0015] According to some embodiments of the utility model, the discharge turning mold further comprises an upper mold plate, the upper mold plate is located above the lower mold plate, the upper mold plate is provided with a plurality of punching needles, and all the punching needles are respectively arranged in a one-to-one correspondence with all the mold holes. Since the rectangular tube is located between the mold hole and the punching needle, when the punching needle is inserted into the mold hole, the punching of the rectangular tube is completed.

[0016] According to some embodiments of the utility model, the lower template is connected to a positioning plate, the positioning plate is located between the lower template and the upper template, the positioning plate is provided with a plurality of positioning holes, and all the positioning holes are respectively arranged in a one-to-one correspondence with all the die holes. Although all the punching needles are respectively arranged in a one-to-one correspondence with all the die holes, during the non-punching period, the punching needle needs to leave the die hole. Since the upper template and the lower template are arranged independently of each other, there will inevitably be a certain deviation in the cooperation between the two, which may cause the punching needle to be unable to align with the die hole during the next punching. The arrangement of the positioning plate enables the punching needle to remain in the positioning hole after leaving the die hole. Since the positioning plate is connected to the lower template, the degree of cooperation between the two is high, which is conducive to the alignment of the punching needle with the die hole.

[0017] According to some embodiments of the utility model, since the mold core needs to be inserted into the inner cavity of the rectangular tube, in order to avoid interference, a space is reserved between the positioning plate and each of the mold cores.

[0018] According to some embodiments of the present invention, although the present invention does not limit the setting direction of the die holes, specifically, the center line of each of the die holes is orthogonal to the first straight line direction.

[0019] The punching assembly according to the second embodiment of the utility model includes:

[0020] A discharge turning mold, wherein two discharge turning molds are provided;

[0021] a conveyor belt having a conveying direction parallel to the first linear direction;

[0022] The movable module is provided with two, and the two movable modules are respectively movably connected to the two sides of the conveyor belt, and the moving direction of the movable module is orthogonal to the conveying direction of the conveyor belt. Each of the movable modules is equipped with one of the discharge turning molds, and all the mold cores located on both sides of the conveyor belt are arranged opposite to each other, and at least one of the discharge turning molds is connected to a stamping mechanism;

[0023] The lifting mechanism is provided with a lifting part that can be raised and lowered, the moving path of the lifting part passes through the conveying surface of the conveyor belt, and the lifting part is located between the two discharge turning molds.

[0024] According to the punching assembly of the embodiment of the utility model, at least the following beneficial effects are achieved: when it is necessary to punch the narrow sides of a plurality of rectangular tubes, firstly, the wide sides of the plurality of rectangular tubes are placed on the conveyor belt as the bottom sides; after the conveyor belt transports the plurality of rectangular tubes to the designated positions, the lifting mechanism lifts the plurality of rectangular tubes upwards through the lifting part; then the two movable modules move in a direction close to the rectangular tubes; each two rotary guide heads respectively extend into the inner cavity of a rectangular tube; during this process, the inner wall of the rectangular tube contacts the first guide slopes of the corresponding two rotary guide heads; as the two rotary guide heads gradually go deeper, the two rotary guide heads force the rectangular tube to move along the two first guide slopes, thereby achieving the separation of two adjacent rectangular tubes; and then the lifting mechanism controls its lifting part to descend, so as to reserve enough space for The rectangular tube is flipped. At this moment, since the rectangular tube loses the support of the lifting part, it flips around the rotary guide head under the action of gravity, and then flips from a horizontal state to a vertical state. After that, the two movable modules continue to move toward the direction close to the conveyor belt until the mold cores on both sides respectively extend into the inner cavity of the corresponding rectangular tube. At this time, the two ends of the rectangular tube are respectively supported outside the two mold cores and cover the mold holes. Finally, the punching of the narrow surface of the rectangular tube is achieved through the stamping mechanism. Compared with the prior art, since the discharge and flipping mold can separate and discharge multiple rectangular tubes arranged side by side, the friction between two adjacent rectangular tubes can be eliminated, so that all rectangular tubes can autonomously flip from a horizontal state to a vertical state during the gravity flipping process, thereby avoiding punching failure.

[0025] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] like Figures 1 to 3As shown, the discharge turning die according to the first embodiment of the utility model comprises a lower base plate 110, a lower template 120 and an upper template 210, wherein the lower template 120 is connected to the lower base plate 110, and the upper template 210 is located above the lower template 120, and the upper template 210 is separately arranged from the lower template 120. Generally speaking, the lower template 120 is a fixed component, and the upper template 210 is a movable component, specifically, the lower base plate 110 is fixedly connected to the base by bolts, and the upper template 210 is fixedly connected to the punch 721 of the punching mechanism 720 by bolts, and when the punching mechanism 720 drives its punch 721 to extend downward, the upper template 210 moves downward toward the lower template 120. However, the present invention does not limit the installation method of the upper template 210 and the lower template 120. In some other embodiments, the lower template 120 can also be a movable component, while the upper template 210 is a fixed component. At this time, the lower base plate 110 is connected to the punch 721 of the stamping mechanism 720, and the upper template 210 is connected to the base.

[0037] Regardless of the installation method of the upper template 210 and the lower template 120, the lower template 120 is provided with a plurality of mold cores 300, and the plurality of mold cores 300 are arranged at intervals along the first straight line direction. For the convenience of description, in this embodiment, the first straight line direction is specifically the front-to-back direction. The plurality of mold cores 300 can be connected to the lower template 120 by bolts, so that different working conditions can be dealt with by replacing different mold cores 300. However, in this embodiment, the lower template 120 is integrally formed with all the mold cores 300. When facing different working conditions, different lower templates 120 can be replaced as a whole to deal with them, thereby improving work efficiency.

[0038] Since the utility model needs to separate and discharge multiple rectangular tubes, the number of mold cores 300 is at least two. In this embodiment, the number of mold cores 300 is five, and the five mold cores 300 are arranged at intervals along the front-to-back direction. The utility model does not limit the spacing between two adjacent mold cores 300, which can be arranged equidistantly or unequally. Since the shape of the mold core 300 needs to match the inner cavity shape of the rectangular tube, each mold core 300 has an upper end face, a lower end face, an inner end face, an outer end face and two side end faces. It can be understood that the upper end face of the mold core 300 faces upward, the lower end face of the mold core 300 faces downward, the inner end face of the mold core 300 is away from the rectangular tube, the outer end face of the mold core 300 is close to the rectangular tube, and the side end faces of two adjacent mold cores 300 face each other. If the lower mold plate 120 is integrally formed with all the mold cores 300, then the inner end face may no longer exist in a separate form. For the convenience of description, the outer end surface of the mold core 300 is defined as a first outer end surface 310 hereinafter.

[0039] In order to be able to flip the multiple rectangular tubes from a horizontal state to an upright state, each first outer end face 310 is provided with a rotary guide head 320, and the projection of the rotary guide head 320 on the first outer end face 310 is located within the size range of the first outer end face 310, that is, the rotary guide head 320 does not exceed the first outer end face 310. Each rotary guide head 320 includes an integrally formed rod portion 321 and a head portion 322, and a mounting hole 311 for mounting the rod portion 321 is provided on the first outer end face 310, and the head portion 322 extends outward from the first outer end face 310, and the head portion 322 can be selected as a cone or a truncated cone, so that the rotary guide head 320 has a first guide inclined surface 323, and at this time, the rotary guide head 320 has a function of guiding rotation in addition to the guiding function.

[0040] During processing, the two discharge flip molds are respectively located on both sides of the plurality of rectangular tubes. When all the rectangular tubes reach the designated position and are lifted, the two discharge flip molds move toward the direction close to the rectangular tubes. Every two rotary guide heads 320 extend into the inner cavity of a rectangular tube respectively. At this time, the moving path of the first guide slope 323 intersects with the inner wall of the rectangular tube. During this process, the inner wall of the rectangular tube contacts the first guide slopes 323 of the corresponding two rotary guide heads 320. As the two rotary guide heads 320 gradually go deeper, the two rotary guide heads 320 force the rectangular tube to move along the two first guide slopes 323, thereby realizing the separation of two adjacent rectangular tubes. When every two adjacent rectangular tubes are separated by the rotary guide heads 320, all the rectangular tubes are in a separated discharge state, thereby eliminating the friction between the two adjacent rectangular tubes. After that, the lifting part 810 for lifting multiple rectangular tubes descends to reserve enough space for the rectangular tubes to flip over. At this moment, since the rectangular tubes lose the support of the lifting part 810, they flip around the rotating guide head 320 under the action of gravity, and then flip from a horizontal state to a vertical state.

[0041] like Figure 2 As shown, the purpose of the present technology is to separate and discharge multiple rectangular tubes through the rotary guide head 320 of the mold core 300. Taking the number of mold cores 300 as five as an example, and marked as #1, #2, #3, #4 and #5 respectively, the following embodiments can achieve the above purpose:

[0042] Embodiment 1: All the mold cores 300 are in the same horizontal plane, wherein the rotary guide heads 320 of at least four mold cores 300 have the first guide slope 323 that can contact the inner wall of the rectangular tube, and the rotary guide heads 320 of the remaining mold cores 300 may not have the first guide slope 323 or even if they have the first guide slope 323, they do not contact the inner wall of the rectangular tube. Through the above-mentioned setting, in the process of separating and discharging multiple rectangular tubes, first determine a rectangular tube that remains stationary, and then the remaining four rectangular tubes are all moved in the horizontal direction under the guidance of the rotary guide head 320, so as to achieve the separation and discharge of all rectangular tubes in the horizontal direction.

[0043] Embodiment 2: Two non-adjacent cores 300 (#2 and #4) are not in the same horizontal plane as the other cores 300 (#1, #3 and #5), wherein the rotary guide heads 320 of at least two cores 300 have a first guide slope 323 that can contact the inner wall of the rectangular tube, and the rotary guide heads 320 of the remaining cores 300 may not have the first guide slope 323 or even if they have the first guide slope 323, they do not contact the inner wall of the rectangular tube. Through the above-mentioned setting, in the process of separating and discharging multiple rectangular tubes, a group of cores 300 located in the same horizontal plane forces the corresponding rectangular tubes to move in the vertical direction through their rotary guide heads 320, and then the remaining rectangular tubes remain stationary, thereby realizing the separation and discharge of all rectangular tubes in the vertical direction.

[0044] Embodiment 3: All the cores 300 are in the same horizontal plane, but the rotary guide heads 320 of two non-adjacent cores 300 (#2 and #4) are not in the same horizontal plane as the rotary guide heads 320 of other cores 300 (#1, #3 and #5), wherein the rotary guide heads 320 of at least two cores 300 have a first guide slope 323 that can contact the inner wall of the rectangular tube, and the rotary guide heads 320 of the remaining cores 300 may not have the first guide slope 323 or even if they have the first guide slope 323, they do not contact the inner wall of the rectangular tube. Through the above-mentioned setting, in the process of separating and discharging multiple rectangular tubes, a group of rotary guide heads 320 located in the same horizontal plane forces the corresponding rectangular tube to move in the vertical direction, and then the remaining rectangular tubes remain stationary, thereby realizing the separation and discharge of all rectangular tubes in the vertical direction.

[0045] For Example 1, the rotary guide heads 320 of the four mold cores 300 can be selected as oblique cone components to expand the moving path of their first guide slopes 323 so that their first guide slopes 323 have a moving path that intersects with the inner wall of the rectangular tube, and the rotary guide heads 320 of the remaining mold cores 300 can be selected as right cone components to limit the moving path of their first guide slopes 323 so that their first guide slopes 323 do not have a moving path that intersects with the inner wall of the rectangular tube.

[0046] Furthermore, if the rotary guide head 320 of the #1 core 300 or the #5 core 300 is selected as a right circular cone component, and the rotary guide heads 320 of the other cores 300 are selected as oblique circular cone components and are all inclined toward the direction close to the #1 core 300 or the #5 core 300, then for the farthest rectangular tube, its position after separation and discharge is far away from the position before separation and discharge, which is not easy to achieve in structure. In order to better separate and discharge the five rectangular tubes, in this embodiment, the rotary guide head 320 of the #3 core 300 is selected as a right circular cone component, and the rotary guide heads 320 of the other cores 300 are selected as oblique circular cone components, and the rotary guide heads 320 of the #1 core 300 and the #2 core 300 are inclined toward the direction close to the #3 core 300, and the rotary guide heads 320 of the #4 core 300 and the #5 core 300 are inclined toward the direction close to the #3 core 300.

[0047] It is understandable that in other embodiments, a technical solution can be adopted to separate and discharge all rectangular tubes in the vertical direction and the horizontal direction. As long as the separation and discharge of multiple rectangular tubes are achieved through the rotary guide head 320 of the core mold 300, no matter how the core mold 300 or the rotary guide head 320 is set, it falls within the protection scope of the present utility model.

[0048] like Figure 1 and Figure 3 As shown, in order to punch the narrow surface of the rectangular tube, the upper end surface of each die core 300 is provided with a die hole 330, and the die hole 330 runs through the die core 300. Correspondingly, the upper die plate 210 is provided with a plurality of punching pins 211, and all the punching pins 211 are respectively arranged in a one-to-one correspondence with all the die holes 330. Taking the lower die plate 120 as a fixed component and the upper die plate 210 as a movable component as an example, when the punch 721 of the stamping mechanism 720 extends downward, it drives the upper die plate 210 to move in the direction of the lower die plate 120 until each punching pin 211 is inserted into the corresponding die hole 330.

[0049] After the rectangular tube is flipped from a horizontal state to an upright state, the two discharge flip dies continue to move toward the direction close to the rectangular tube until the mold cores 300 located on both sides extend into the inner cavity of the corresponding rectangular tube respectively. At this time, the two ends of the rectangular tube are supported outside the two mold cores 300 and block the mold holes 330. Finally, the stamping mechanism 720 drives the upper mold plate 210 to move toward the lower mold plate 120 to punch out a circular hole on the narrow surface of the rectangular tube. Since the mold hole 330 runs through the mold core 300, the waste of the punching sheet can be discharged outside the mold core 300 to avoid blockage. When it is necessary to punch two narrow surfaces of the rectangular tube at the same time, the moving path of the punch needle 211 should run through the entire rectangular tube, and the waste of the punching sheet completely leaves the rectangular tube; when only one narrow surface of the rectangular tube needs to be punched, the moving path of the punch needle 211 only needs to run through the upper surface of the rectangular tube, and the waste of the punching sheet remains in the inner cavity of the rectangular tube.

[0050] Furthermore, the lower template 120 is connected with a positioning plate 400, and the positioning plate 400 is located between the lower template 120 and the upper template 210. The positioning plate 400 is provided with a plurality of positioning holes 410, and all the positioning holes 410 are respectively arranged in a one-to-one correspondence with all the die holes 330. Although all the punching needles 211 are respectively arranged in a one-to-one correspondence with all the die holes 330, during the non-punching period, the punching needles 211 need to leave the die holes 330. Since the upper template 210 and the lower template 120 are arranged independently of each other, there will inevitably be a certain deviation in the cooperation between the two, which may cause the punching needle 211 to be unable to align with the die hole 330 during the next punching period. The arrangement of the positioning plate 400 allows the punching needle 211 to remain in the positioning hole 410 after leaving the die hole 330. Since the positioning plate 400 is connected to the lower template 120, the degree of cooperation between the two is relatively high, which is conducive to the alignment of the punching needle 211 with the die hole 330.

[0051] It should be noted that, since the mold core 300 needs to be inserted into the inner cavity of the rectangular tube, in order to avoid interference, a clearance space 420 is reserved between the positioning plate 400 and each mold core 300. In order to allow the mold core 300 to be smoothly inserted into the inner cavity of the rectangular tube, the four sides of each first outer end face 310 are chamfered to form a second guide slope 340, and the height of the second guide slope 340 gradually increases from the first outer end face 310. When the mold cores 300 located on both sides gradually extend into the openings on both sides of the rectangular tube, the two ends of the rectangular tube can be positioned and supported outside the two mold cores 300 through the second guide slopes 340, thereby fixing the position of the rectangular tube.

[0052] In some embodiments of the present invention, although the present technology does not limit the setting direction of the die hole 330, the die hole 330 can be set obliquely or vertically, but in this embodiment, the center line of each die hole 330 is orthogonal to the first straight line direction, so as to select the technical solution of vertically setting the die hole 330. Of course, when the customer has special process requirements, the die core 300 with an inclined die hole 330 can also be replaced, and at this time, the stamping mechanism 720 also needs to extend and retract its punch 721 at an inclined angle.

[0053] like Figure 4 As shown, the punching assembly according to the second embodiment of the utility model includes the discharge flip mold according to the above-mentioned first embodiment of the utility model, and also includes a frame 500, a conveyor belt 600, a movable module 700 and a lifting mechanism 800. The front and rear sides of the frame 500 are respectively provided with a first slide rail 510 arranged along the left and right directions. The frame 500 is connected with a conveyor belt 600, and the conveyor belt 600 has a conveying direction from back to front. The conveying end of the conveyor belt 600 is provided with a downwardly inclined unloading plate 610. The conveyor belt 600 can be selected as a conveyor belt 600 with a certain width, or it can be composed of two conveying sub-lines 620 that are parallel to each other and spaced apart. In this embodiment, in order to adapt to rectangular tubes of different lengths, the conveyor belt 600 is preferably composed of two conveying sub-lines 620 that are parallel to each other and spaced apart.

[0054] Specifically, each of the conveying branch lines 620 is a narrow conveyor belt 600, one of which is fixedly connected to the frame 500 through a mounting plate 630, and the other conveying branch line 620 is slidably connected to the two first slide rails 510 of the frame 500 through an external slide plate 640, so that the spacing between the two conveying branch lines 620 is adjustable. In order to adjust the spacing between the two conveying branch lines 620, the mounting plate 630 is connected to a lead screw 650 through a bearing seat, the slide plate 640 is provided with a nut block 651 threadedly connected to the lead screw 650, and a hand wheel 652 is provided at the end of the lead screw 650. When the user rotates the hand wheel 652, the lead screw 650 also rotates, and then drives the nut block 651 to move along the length direction of the lead screw 650, and finally realizes the spacing adjustment of the two conveying branch lines 620.

[0055] In addition, the number of movable modules 700 and the number of discharge flip molds are both two, and the two movable modules 700 are respectively located on the left and right sides of the conveyor belt 600. The upper surface of the slide plate 640 connected to the conveying branch line 620 is provided with two second slide rails arranged along the left and right directions, and one of the movable modules 700 is slidably connected to the two second slide rails of the slide plate 640, and a first oil cylinder is connected between the movable module 700 and the slide plate 640, and the position of the movable module 700 on the slide plate 640 is controlled by the first oil cylinder. At the same time, another movable module 700 is slidably connected to the two first slide rails 510 of the frame 500, and a second oil cylinder is connected between the movable module 700 and the fixed conveying branch line 620, and the position of the movable module 700 on the frame 500 is controlled by the second oil cylinder. In summary, the moving directions of the two movable modules 700 are orthogonal to the conveying direction of the conveyor belt 600. When the user rotates the handwheel 652, the movable conveying branch line 620 and the movable module 700 connected thereto can move relative to the fixed conveying branch line 620 at the same time to adapt to rectangular tubes of different lengths. After the user adjusts the relative positions of the various components according to the size of the rectangular tubes, the two movable modules 700 can approach or move away from the conveyor belt 600 at the same time under the drive of their respective cylinders.

[0056] The two discharge turning molds are respectively installed on the two movable modules 700, and all the mold cores 300 on both sides of the conveyor belt 600 are arranged opposite to each other. Among them, the lower bottom plate 110 of the discharge turning mold is fixedly connected to the movable module 700 by bolts, and the movable module 700 is connected with a punching mechanism 720 above the lower mold plate 120, and the punching mechanism 720 is connected to the movable module 700 through a guide sleeve and a guide column. The punching mechanism 720 can be selected as an oil cylinder or an air cylinder, and its punch 721 is fixedly connected with a guide plate 722, and the guide plate 722 is connected along the guide column for guiding, and the upper mold plate 210 is fixedly connected to the guide plate 722 by bolts.

[0057] Since the rectangular tube is transported under the drive of the conveyor belt 600, before punching the rectangular tube, it is necessary to limit the position of the rectangular tube on the conveyor belt 600, so that when the two movable modules 700 are close to the conveyor belt 600 at the same time, all the rotary guide heads 320 located on the front and rear sides can extend into the openings on both sides of the corresponding rectangular tube. To this end, the two conveying branch lines 620 are connected with a material blocking mechanism 900, which can be a cylinder. The material blocking mechanism 900 is provided with a material blocking part 910 that rises and falls in the up and down direction, and each material blocking part 910 is connected with a first induction switch, and the material blocking part 910 can rise to a conveying surface higher than the conveyor belt 600, or fall to a conveying surface lower than the conveyor belt 600. When multiple rectangular tubes are placed on the conveyor belt 600 at the same time, if the first rectangular tube is blocked by the material blocking part 910, the multiple rectangular tubes are arranged side by side in the front and back direction, so that all the rotary guide heads 320 located on the left and right sides can accurately extend into the openings on both sides of the corresponding rectangular tube.

[0058] Finally, in order to flip the rectangular tube from a horizontal state to an upright state, the conveyor belt 600 is connected to a lifting mechanism 800 at an upstream position of the blocking mechanism 900. Since the conveyor belt 600 is composed of two conveying branch lines 620, the number of the lifting mechanisms 800 can be selected to be two, and the two lifting mechanisms 800 are respectively connected to the two conveying branch lines 620. The lifting mechanism 800 can be selected as a cylinder, which is provided with a lifting part 810 that rises and falls in the up and down directions. The upper surface of each lifting part 810 is provided with a magnetic part 811, and the magnetic part 811 can be selected as a permanent magnet. The lifting part 810 can rise to a conveying surface higher than the conveyor belt 600, or fall to a conveying surface lower than the conveyor belt 600, and the lifting part 810 is located between the two discharge flip molds, so that the rising path of the rectangular tube can intersect with the moving path of the mold core 300. It can be understood that the lifting mechanism 800 can also be connected to the frame 500, and is not limited to the above embodiment.

[0059] With the above structure, when it is necessary to punch the narrow side of the rectangular tube, firstly, the wide sides of the plurality of rectangular tubes are placed as the bottom side on the conveyor belt 600, and the conveyor belt 600 conveys the plurality of rectangular tubes, and the blocking portion 910 of the blocking mechanism 900 is higher than the conveying surface of the conveyor belt 600, thereby limiting the position of the plurality of rectangular tubes on the conveyor belt 600. After a period of time has passed since the first induction switch on the blocking portion 910 was triggered, the lifting mechanism 800 drives the lifting portion 810 to lift the plurality of rectangular tubes upwards. In this embodiment, the lifting height of the lifting portion 810 is limited by setting a second induction switch, so that the rectangular tubes can match the height of the rotary guide head 320. After that, the two movable modules 700 are driven by their respective oil cylinders to move toward the conveyor belt 600 until the rotary guide heads 320 on both sides extend into the inner cavity of the corresponding rectangular tube, and each two rotary guide heads 320 extend into the inner cavity of a rectangular tube. During this process, the inner wall of the rectangular tube contacts the first guide slopes 323 of the corresponding two rotary guide heads 320. As the two rotary guide heads 320 gradually go deeper, the two rotary guide heads 320 force the rectangular tube to move along the two first guide slopes 323, thereby separating the two adjacent rectangular tubes. Then, the lifting mechanism 800 controls its lifting part 810 to descend, and the material blocking mechanism 900 controls its material blocking part 910 to descend, so as to reserve enough space for the rectangular tube to flip. At this moment, since the rectangular tube loses the support of the lifting part 810, the rectangular tube can flip around the rotating guide head 320 under the action of gravity, and at the moment when the lifting part 810 leaves the rectangular tube downward, the magnetic part 811 strengthens the inertial deflection of the rectangular tube through magnetic force, thereby flipping the rectangular tube from a horizontal state to a vertical state.

[0060] Subsequently, the two movable modules 700 continue to move in the direction close to the conveyor belt 600 until the mold cores 300 on both sides extend into the inner cavity of each rectangular tube respectively. When the mold cores 300 on both sides gradually extend into the openings on both sides of the rectangular tube, the two ends of each rectangular tube can be positioned and supported outside the two mold cores 300 and cover the mold holes 330 through the second guide slopes 340, thereby fixing the position of each rectangular tube. Finally, the stamping mechanism 720 drives the upper mold plate 210 to stamp in the direction of the mold holes 330, thereby completing the punching of the narrow surface of the rectangular tube. It should be noted that since the upper surface of the lifting part 810 is provided with a magnetic part 811, the relative positions between the multiple rectangular tubes are temporarily fixed during the process of the lifting part 810 lifting the multiple rectangular tubes upward, thereby avoiding the deviation of the positions of the multiple rectangular tubes during the lifting process.

[0061] After punching, the upper template 210 is reset upwards under the drive of the punching mechanism 720, and the two movable modules 700 are driven by their respective cylinders to move in a direction away from the conveyor belt 600, so that the plurality of rectangular tubes can fall back onto the conveyor belt 600. Once the plurality of rectangular tubes pass over the blocking portion 910, the blocking mechanism 900 drives the blocking portion 910 to rise, and finally the plurality of rectangular tubes are unloaded under the conveyance of the conveyor belt 600. Since the rectangular tubes can be unloaded directly after punching, even if the rectangular tubes fall over when they fall back onto the conveyor belt 600, it will not affect the subsequent unloading.

[0062] In other embodiments, if single-side punching is performed on a plurality of rectangular tubes, only one of the movable modules 700 needs to be provided with a punching mechanism 720 , or only one of the two punching mechanisms 720 needs to be activated.

[0063] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
