Detailed Description of the Embodiment

[0039] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0040] The present invention will be described in detail below with reference to the accompanying drawings. The present embodiment discloses a quick-change gantry device, such as Figure 1 As shown, it includes a base plate 1, which is used to be set on the frame; a parallel guide plate 2 is fixed to the left and right sides of the top surface of the base plate 1, and a gantry 5 is slidably set between the two parallel guide plates 2, and the gantry 5 can slide relative to the base plate 1. A hydraulic cylinder 8 is fixed on the top of the gantry 5, and the hydraulic cylinder 8 is connected to a sliding block 6 through a connecting sleeve 7. The sliding block 6 is slidably set inside the gantry 5; the mold is located directly below the sliding block 6 and is detachably set inside the gantry from the side of the gantry 5. An adjustment mechanism 10 is also provided between the gantry 5 and the base plate 1, and the adjustment mechanism 10 can drive the gantry 5 to slide relative to the base plate 1.

[0041] like Figure 1 、 Figure 2 As shown, the gantry 5 includes two side panels 51, which together with the rear panel, the top panel, and the support frame 52 form the gantry frame, wherein the top panel is shorter than the side panels; the panels are fixedly connected by bolts; Figure 1 、 Figure 2 As shown, the hydraulic cylinder 8 is fixedly arranged at the center position of the top of the support frame 52. It should be noted that the position of the hydraulic cylinder 8 relative to the support frame 52 remains unchanged; the bottom of the side plate 51 is slidably connected to the parallel guide plate 2. Figure 4 As shown, a sliding slot 511 is fixedly connected to the bottom of the side panel 51, and a sliding protrusion is provided on the top of the side of the parallel guide plate 2 facing the side panel 51. The sliding protrusion matches the sliding slot 511. The sliding slots 511 on the two side panels 51 cooperate with the sliding protrusions of the two parallel guide plates 2, thereby realizing a sliding connection between the side panel 51 and the parallel guide plate 2.

[0042] like Figure 2 As shown, the gantry 5 also includes a first transverse plate 53 and a second transverse plate 54 of identical dimensions, disposed between the two side panels 51. A third transverse plate 55 is disposed between the first and second transverse plates 53, 54. It should be noted that the third transverse plate 55 is shorter than the first and second transverse plates 53, 54. All three transverse plates are perpendicular to the side panels 51 and arranged parallel to each other. The first and third transverse plates 53, 55 are spaced a certain distance apart for accommodating profiles. The third transverse plate 55 is fixedly connected to the second transverse plate 54. Two cylindrical beams are also disposed between the side panels 51 to reinforce the connection. The third transverse plate 55 protrudes from the gantry toward the side of the side panel away from the rear panel.

[0043] likeFigure 3 As shown, on the opposite sides of the two side plates 51, limiting and guiding grooves 512 are provided. The sliding block 6 is restricted between the two limiting and guiding grooves 512. Driven by the hydraulic cylinder 8, the sliding block 6 makes vertical reciprocating motions along the limiting and guiding grooves 512. When the output end of the hydraulic cylinder 8 is at the starting position, the device is in the starting state.

[0044] As Figure 1 、 Figure 2 shown, the center of the top of the sliding block 6 is fixedly connected to the center of the bottom of the connecting sleeve 7. The output shaft of the hydraulic cylinder 8 is fixedly wrapped inside the cylindrical connecting sleeve 7, and the center of the output shaft of the hydraulic cylinder 8 and the center of the connecting sleeve 7 are at the same point; this is to ensure that the output shaft of the hydraulic cylinder 8 and the center of the sliding block are coaxial.

[0045] As Figure 2 、 Figure 6 、 Figure 7 shown, the mold 9 is an inlaid separation structure, including a mold core 91. Multiple guiding holes 911 are provided inside the mold core 91. Multiple insert seats 912 are provided on the top surface of the mold core. The insert seats 912 and the centers of the guiding holes 911 are aligned. Multiple inserts 92 are detachably arranged inside the insert seats 912. According to the inner diameters of the inserts 92, they can be divided into multiple specifications. It should be noted that the inner diameter of the guiding hole 911 is larger than the inner diameter of the insert 92. The outer periphery of the insert can be engaged into the insert seat and connected by friction, and will not fall off easily.

[0046] As Figure 2 、 Figure 6 、 Figure 7 shown, the mold 9 further includes a fixing block 95. Multiple punch seats with the same size are provided at the bottom of the fixing block 95; multiple punches 94 are detachably arranged on the fixing block 95. The punch 94 includes a punch plate, and the punch plate is fixedly connected to the punch body. The punch plate is detachably arranged inside the punch seat. It can be understood that the punch plate and the punch seat have the same size, and the punch plate can be engaged into the punch seat and connected by friction, and will not fall off easily. The punches 94 can be divided into multiple specifications according to the thickness of the punch body. The center of the punch is set on the short side center line of the fixing block. Similarly, the centers of the insert and the guiding part are respectively set on the short side center lines of the mold core and the guiding part. The inner diameter of the guiding hole 911 is larger than the inner diameter of the radial cross-section of the punch body.

[0047] It can be understood that the position of the punch seat corresponds to the position of the insert seat, and the center of the punch seat corresponds to the center of the insert seat. The punches 94 and the inserts 92 are used in matching. Punches 94 of the same specification can pass through the inner diameter of the insert 92. As Figure 6 、 Figure 7As shown, the mold 9 further includes a guide member 93, and a guide hole is also provided in the guide member 93. The position of the guide hole corresponds to the positions of the punch 94 and the insert 92 one by one. It should be noted that when the output end of the hydraulic cylinder 8 is in the starting position, that is, when punching has not been performed and the device is in the starting state, the end of the punch 94 away from the sliding block is flush with the bottom of the guide member.

[0048] As Figure 2 , Figure 3 , Figure 5 As shown, a fixing block groove 61 is formed at the bottom of the sliding block 6. The fixing block groove 61 is perpendicular to the side plate 51 and is symmetric about the short-side center line of the sliding block 6 for setting the fixing block. Right below the fixing block groove 61, a guide member groove 531 is formed on the first horizontal plate 53 for setting the guide member; a die core groove 551 is formed on the third horizontal plate 55 for setting the die core; a waste groove 541 is formed on the second horizontal plate 54 for discharging waste; the short-side center lines of the guide member groove 531, the waste groove 541, the die core groove 551, and the fixing block groove 61 correspond.

[0049] As Figure 2 As shown, the die core 91 is inserted into the die core groove 551 for setting, the guide member 93 is inserted into the guide member groove 531 for setting, and the fixing block 95 is inserted into the fixing block groove 61 for setting and is fixed by friction; it is not difficult to find that the short-side center line of the mold 9 in this embodiment always coincides with the short-side center line of the sliding block 6, which can also ensure that the center of the mold 9 is always coaxial with the output shaft of the hydraulic cylinder 8. When the hydraulic cylinder 8 drives the sliding block 6 to descend, the fixing block 95 drops, and multiple punches 94 pass through the corresponding guide holes of the guide member, then pass through the profile between the guide member 93 and the die core 91, and finally drive the waste of the punching through the insert 92.

[0050] As Figure 5 As shown, a first side opening 513 is formed on the side plate 51. The length of its long side is set according to the size of the profile, and the length of its wide side is equal to the distance between the first horizontal plate and the third horizontal plate, for ensuring that the profile passes through and enters the inside of the gantry; guide blocks 3 are arranged on the upper and lower sides of the first side opening 513 to provide guidance for the profile to enter and exit the gantry 5; above the upper guide block 3, a pressing plate 4 is fixed to the side plate 51 by bolts outside the guide member groove 531. It can be understood that below the lower guide block 3, a pressing plate 4 is fixed to the side plate 51 by bolts outside the die core groove 551.

[0051] It can be understood that the pressing plate 4 can prevent the die core and the guide member from sliding out of the gantry 5. At the same time, since the punch 94 is always located inside the guide member, the pressing plate 4 can fix the mold 9 inside the gantry 5.

[0052] As Figure 5As shown, a second side opening 514 is further formed on the side plate 51. The second side opening 514 is perpendicular to the first side opening 513. The bottom of the second side opening 514 is flush with the bottom of the die core groove. When the output end of the hydraulic cylinder 8 is in the starting state, the top of the fixed block groove is flush with the top of the second side opening 514. The width of the second side opening 514 is the same as the widest width among the die core groove, the guide member groove, and the fixed block groove.

[0053] As Figure 2 shown, the adjusting mechanism 10 includes a nut seat 102 arranged at the middle position on the side of the second cross plate 54 away from the rear plate, and a fixing plate 101 arranged at the middle position on the side of the bottom plate away from the rear plate. A screw rod is arranged between the fixing plate 101 and the nut seat 102. A handle is arranged at the top of the screw rod. By rotating the handle, the distance between the nut seat and the fixing plate is changed, so as to adjust the position of the gantry 5 relative to the bottom plate 1.

[0054] A waste opening is arranged on the bottom plate 1 for discharging the waste falling from the waste chute 541.

[0055] The positions of the holes on different profiles are different. When replacing different profiles, the positions of the corresponding hydraulic cylinders need to be adjusted. At this time, the position of the entire gantry 5 can be directly adjusted through the adjusting mechanism. Then, according to the requirements of the profile, the die 9 is disassembled, and the corresponding number of punch heads is arranged on the fixed block. It can be understood that the distance between the punch heads can be adjusted. For example, in this embodiment, the number of punch heads is six. One type of profile uses six punch heads, while another type of profile only uses three punch heads, namely the first, fourth, and sixth punch heads. Moreover, for different profiles, the specifications and combinations of the punch heads used are also different. Just replace the punch heads and the corresponding inserts with the corresponding specifications as required. The utility model can conveniently adjust the position of the hydraulic cylinder when the specification model of the processed profile changes, without the need to disassemble / install a large number of bolts, saving the adjustment time. And the main axis of the piston rod of the hydraulic cylinder is always coaxial with the center line of the die, which can ensure the punching accuracy; there is no need to manufacture a large number of dies, saving costs.

[0056] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
