[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.

[0033] As Figures 1 to 10 shown, a medal fringing device in this embodiment includes a base 1, the base 1 is provided with an installation groove, and a first sliding table 2 is installed in the installation groove; it further includes a feeding support 3 fixedly installed above the base 1 and a mold 4 arranged to be lifted on the feeding support 3;

[0034] The output end of the first sliding table 2 is slidably provided with two oppositely arranged flanging sliders 5, and the inner side of the flanging slider 5 is provided with a flanging surface structure 51; the flanging slider 5 is further provided with a heating plate 52; the base 1 is provided with guiding and driving grooves on both sides of the first sliding table 2, that is, the two guiding and driving grooves are distributed on both sides of the installation groove, and the bottom of the flanging slider 5 is elastically provided with a slide pin 53; the slide pin 53 is movably embedded in the corresponding guiding and driving groove; the bottom of the flanging slider 5 is elastically slidably provided with an unloading push block 54; the base 1 is respectively provided with driving bosses 12 for cooperating with the unloading push block 54 on the outer sides of the guiding and driving grooves; the feeding support 3 is provided with a feeding groove 31 and a pushing component at the bottom of the feeding groove 31; the end of the mold 4 away from the feeding groove 31 is provided with a blocking boss 41. In this embodiment, a cylinder 8 is fixedly installed on the feeding support 3, and the output end of the cylinder 8 is fixedly connected to the mold 4, and the mold 4 is driven to perform lifting movement by the cylinder 8.

[0035] Specifically, when the medal ribbon tab hemming device of this embodiment is actually applied, the metal sheet dovetail grooves are stacked in the feeding groove 31 in sequence. The cylinder 8 drives the mold 4 to the top dead center position. At this time, the pushing component pushes the metal sheet dovetail groove at the bottommost layer out of the feeding groove 31, so that the metal sheet dovetail groove is pushed onto the mold 4 until the metal sheet dovetail groove abuts against the blocking boss 41. Place the ribbon patch with hot melt adhesive on the hemming surface structure 51 of the two hemming sliders 5. The cylinder 8 drives the mold 4 to move to the bottom dead center position. Then the first slide drives the two hemming sliders 5 to move, and the sliding pin 53 moves along the track of the guiding drive groove, so that the two hemming sliders 5 approach and abut against each other. Until the ribbon patch abuts against the blocking boss 41, the ribbon patch and the metal sheet dovetail groove are automatically aligned. As Figure 2 shown, as the hemming slider 5 continues to move, a relative movement is generated between the hemming slider 5 and the ribbon patch. At this time, the hemming surface structure 51 of the hemming slider 5 performs a hemming process on the ribbon patch, so that the ribbon patch is folded and attached to the surface of the metal sheet dovetail groove. The heating plate 52 works. During the movement of the hemming slider 5, the heating plate 52 heats the hot melt adhesive on the ribbon patch, so that the hot melt adhesive on the ribbon patch melts, and then the ribbon patch is bonded to the surface of the metal sheet dovetail groove to obtain the medal ribbon tab. As Figure 3 shown;

[0036] After the heating is completed, the first slide table 2 drives the hemming slider 5 to move in the reverse direction. At this time, under the cooperation of the guiding drive groove and the sliding pin 53, the two hemming sliders 5 move away from each other. When the driving boss 12 contacts and cooperates with the unloading push block 54, the driving boss 12 causes the unloading push block 54 to protrude upward from the hemming surface structure 51. As Figure 4 shown, when the unloading push block 54 moves to abut against the medal ribbon tab, as the hemming slider 5 moves, the unloading push block 54 pushes the medal ribbon tab to gradually disengage from the mold 4 until the medal ribbon tab completely disengages from the mold 4. After the medal ribbon tab disengages, the mold 4 moves up to the top dead center position. Until the driving boss 12 disengages from the unloading push block 54, the medal ribbon tab is pushed out of the working area to achieve unloading, thus completing the hemming and forming process of the medal ribbon tab.

[0037] In this embodiment, two hemming sliders 5 with hemming surface structures 51 are provided, and a heating plate 52 is arranged on the hemming slider 5. Thus, the pushing component pushes the metal sheet dovetail groove onto the mold 4, and the blocking boss 41 is used for limiting. Then, through the blocking boss 41, a relative movement is generated between the ribbon patch and the hemming slider 5, so that the hemming surface structure 51 is used to perform a hemming and attaching process on the ribbon patch. Through the heating of the heating plate 52, the ribbon patch is bonded to the metal sheet dovetail groove; then, the cooperation between the unloading push block 54 and the driving boss 12 is used to realize the unloading of the medal ribbon tab, thus realizing the hemming and forming process of the medal ribbon tab, with higher processing efficiency, better product consistency, and reduced labor intensity.

[0038] As Figure 7 shown, in some embodiments of a hemming device for military service medal ribbons and clasps according to this embodiment, the guiding and driving groove includes a first parallel section 111, a first inclined section 112, a second parallel section 113, and a second inclined section 114 that are connected end to end in sequence; the first parallel section 111 and the second parallel section 113 are arranged parallel to each other, and the first parallel section 111 is located inside the second parallel section 113; a step 115 is provided between the second parallel section 113 and the second inclined section 114, and a transition inclined surface 116 is provided inside the second inclined section 114.

[0039] Specifically, initially, the sliding pin 53 is located at one end of the second inclined section 114 close to the second parallel section 113. The webbing patch is placed on the two hemming surface structures 51, and then the first sliding table 2 drives the hemming slider 5 to move. The sliding pin 53 moves along the second inclined section 114, causing the two hemming sliders 5 to move towards each other until the sliding pin 53 enters the first horizontal section from the second inclined section 114. At this time, the two hemming sliders 5 are in a state of being in contact with each other. The sliding pin 53 moves along the first horizontal section, so as to perform hemming on the webbing patch through the hemming surface structures 51 of the two hemming sliders 5, making the webbing patch fit on the surface of the dovetail groove of the metal sheet. The heated plate 52 is used to heat the hemmed webbing patch, so that the webbing patch is bonded to the surface of the dovetail groove of the metal sheet, automatically realizing the hemming and fitting process of the webbing patch, with high processing efficiency. Until the sliding pin 53 enters the first inclined section 112 from the first horizontal section, the sliding pin 53 moves along the first inclined section 112, causing the two hemming sliders 5 to move away from each other, and the sliding pin 53 moves to the junction of the first inclined section 112 and the second horizontal section;

[0040] When the first sliding table 2 drives the hemming slider 5 to move in the reverse direction, the sliding pin 53 moves along the track of the second horizontal section, so that the unloading push block 54 cooperates with the driving boss 12, thereby enabling the unloading push block 54 to separate the military service medal ribbon and clasp after the hemming forming process from the mold 4 until the sliding pin 53 crosses the step 115 and returns to the second inclined section 114.

[0041] As Figure 3 and Figure 8 shown, in some embodiments of a hemming device for military service medal ribbons and clasps according to this embodiment, the heated plate 52 is arranged on the hemming surface structure 51 and is adapted to the hemming surface structure 51. With such an arrangement, the heated plate 52 can fully heat the hot melt adhesive on the webbing patch, and the heating is more uniform, so that the webbing patch is more firmly bonded to the dovetail groove of the metal sheet, and the hemming forming effect is better.

[0042] As Figure 3 、 Figure 4 and Figure 8As shown in the figure, a hemming device for military decoration ribbons and medals in this embodiment. In some embodiments, a first spring 55 is connected between the hemming slider 5 and the first slide 2. In this embodiment, by setting the first spring 55, when the sliding pin 53 is located on the first inclined section 112 and moves along the first inclined section 112, the first spring 55 resumes its deformation and pushes the hemming slider 5 to slide outward until the sliding pin 53 enters the second horizontal section. When the sliding pin 53 is located in the second inclined section 114 and moves along the second inclined section 114, the hemming slider 5 moves inward against the elastic force of the first spring 55 until the sliding pin 53 enters the first horizontal section.

[0043] As Figure 8 As shown in the figure, a hemming device for military decoration ribbons and medals in this embodiment. In some embodiments, a chute 56 is recessed inward at the bottom of the hemming slider 5. A second spring 57 is provided in the chute 56. The unloading push block 54 is slidably disposed in the chute 56 and connected to the second spring 57. In this embodiment, by setting the chute 56, it is convenient for the installation of the second spring 57 and the unloading push block 54, and at the same time provides guidance and limitation for the unloading push block 54, making the movement of the unloading push block 54 more stable. By setting the second spring 57, when the unloading push block 54 cooperates with the driving boss 12, the unloading push block 54 can compress the second spring 57 and move upward along the chute 56, so that when the hemming slider 5 returns, the military decoration ribbon and medal can be detached from the mold 4, realizing the effect of automatic unloading, making the hemming operation more convenient and efficient.

[0044] As Figure 3 and Figure 6 As shown in the figure, a hemming device for military decoration ribbons and medals in this embodiment. In some embodiments, a first inclined surface 121 is provided at the end of the driving boss 12 away from the feeding groove 31; the unloading push block 54 is provided with a second inclined surface 541. Specifically, when the first slide 2 drives the hemming slider 5 to return, since the two hemming sliders 5 cooperate with the sliding pins 53 on the first inclined section 112 respectively, the hemming sliders 5 move outward, so that the unloading push block 54 moves to a position corresponding to the driving boss 12. As the hemming slider 5 moves, the second inclined surface 541 of the unloading push block 54 contacts the first inclined surface 121 of the driving boss 12, and the driving boss 12 exerts an extrusion force on the unloading push block 54, making the unloading push block 54 move upward against the elastic force of the second spring 57, so as to protrude above the hemming surface structure 51 until the unloading push block 54 contacts the hemmed military decoration ribbon and medal, and exerts a thrust on the military decoration ribbon and medal, making the military decoration ribbon and medal gradually detach from the mold 4, thus realizing the unloading operation.

[0045] As Figure 8As shown in the figure, a hemming device for military service medals and ribbons according to this embodiment. In some embodiments, a receiving hole is provided at the bottom of the hemming slider 5. A third spring 58 is provided in the receiving hole. The sliding pin 53 is slidably inserted into the receiving hole and connected to the third spring 58. By providing the receiving hole in this embodiment, it is convenient for the installation of the third spring 58 and the sliding pin 53. By providing the third spring 58, the sliding pin 53 can always maintain the cooperation with the guiding drive groove, and the structural reliability is higher.

[0046] As Figure 5 As shown in the figure, a hemming device for military service medals and ribbons according to this embodiment. In some embodiments, the feeding assembly includes a second slide table 61, a feeding block 62 provided at the output end of the second slide table 61, and a feeding channel 63 penetrating through the feeding support 3; the feeding channel 63 is communicated with the feeding groove 31; the feeding block 62 is located in the feeding channel 63. Initially, the second slide table 61 drives the feeding block 62 to move to the end of the feeding channel 63 away from the mold 4. When feeding is required, the second slide table 61 drives the feeding block 62 to move along the feeding channel 63, so as to push the dovetail groove of the metal sheet located in the feeding channel 63 onto the mold 4, thereby realizing the feeding operation until the dovetail groove of the metal sheet completely enters the mold 4. At this time, the dovetail groove of the metal sheet in the feeding groove 31 is blocked by the feeding block 62 and cannot enter the feeding channel 63. Then the second slide table 61 drives the feeding block 62 to reset. At this time, the lowermost dovetail groove of the metal sheet in the feeding groove 31 enters the feeding channel 63 to wait for the pushing of the feeding block 62; in this way, there is no need for manual operation to place the dovetail groove of the metal sheet on the mold 4, and the processing efficiency is higher.

[0047] As Figure 5 and Figure 10 As shown in the figure, a hemming device for military service medals and ribbons according to this embodiment. In some embodiments, a blanking slider 71 and a locking slider 72 are slidably provided at one end of the base 1 close to the feeding groove 31. A fourth spring 73 is connected between the blanking slider 71 and the base 1; the blanking slider 71 protrudes from the top surface of the base 1 under the action of the fourth spring 73; the two locking sliders 72 are distributed on both sides of the blanking slider 71; a tension spring 74 is connected between the locking slider 72 and the base 1; the sliding direction of the locking slider 72 is perpendicular to the sliding direction of the blanking slider 71; the blanking slider 71 is provided with a third inclined surface 711, and the locking slider 72 is provided with a fourth inclined surface 721; the locking slider 72 is cooperated with the third inclined surface 711 through the fourth inclined surface 721 under the action of the tension spring 74, so that the blanking slider 71 retracts into the base 1.

[0048] Specifically, initially, under the pulling force of the tension springs 74, the two locking sliders 72 cooperate with the third inclined surfaces 711 through the fourth inclined surfaces 721, applying a downward pressure to the blanking slider 71, causing the blanking slider 71 to retract into the base 1 against the elastic force of the fourth spring 73. When the unloading push block 54 pushes the hemmed and formed military medal out of the mold 4 until the center of gravity of the military medal crosses the position of the blanking slider 71, as the hemming slider 5 moves, the hemming slider 5 contacts the locking slider 72 and pushes the locking slider 72 to slide against the pulling force of the tension spring 74, so that the locking of the blanking slider 71 by the locking slider 72 is released. At this time, the blanking slider 71 protrudes outwards under the elastic force of the fourth spring 73, thereby lifting the military medal for blanking of the military medal, so as to perform hemming and forming of the next military medal.

[0049] As Figure 5 shown, in a military medal hemming device of this embodiment, in some embodiments, a blanking chute 75 is provided at one end of the base 1 close to the feeding chute 31; the blanking chute 75 is located between the two locking sliders 72. By providing the blanking chute 75 in this embodiment, the hemmed and formed military medal can be moved out of the working area.
