Description

Technical Field

[0001] The invention relates to the field of die cutting machines, in particular to an automatic pop-up and locking device for a movable steel plate. Background Art

[0002] The flat die-cutting machine has a set of movable hardened steel plates on the lower die table to counter the die-cutting edge and install the indentation die. The movable steel plate must have a certain thickness to prevent deformation, so the steel plate will be heavier. Especially for large-format machines, the size of the steel plate will also increase, and the overall weight of the movable steel plate will be heavier. In addition, traditional machines use screws or cylinders to lock the movable steel plate on the lower die table. When the operator installs and checks the indentation die, the locking device must be loosened and the steel plate must be manually pulled out. However, after the machine has been working continuously for a long time, the fit between the movable steel plate and the lower die table becomes closer. In addition, the weight of the movable steel plate itself requires a lot of effort to manually pull out the steel plate, and even requires the assistance of multiple people. The operating experience is very poor, which also affects the production efficiency of the equipment. Summary of the invention

[0006] When in use, when the translation drive mechanism is extended, the slider is extended accordingly, and drives the lock hook swing arm to rotate clockwise on the shaft seat through the connecting rod, so that the first protrusion hooks out of the fixed plate, thereby popping out the movable steel plate;

[0007] When the translation drive mechanism contracts, the slider contracts accordingly, and drives the locking hook swing arm to rotate counterclockwise on the rotating shaft seat through the connecting rod, so that the second protrusion abuts against the fixed plate, thereby locking the movable steel plate.

[0008] Furthermore, the translation driving mechanism includes a cylinder and a cylinder fixing seat, the cylinder fixing seat is installed on the mold platform and fixedly connected to the cylinder, and the output end of the cylinder is connected to the slider.

[0009] Furthermore, the translation drive mechanism also includes a cylinder magnetic induction switch, which is fixedly connected to the cylinder and is used to detect the position of the piston rod in the cylinder.

[0011] Furthermore, side support strips are provided on both sides of the movable steel plate, and multiple bearings are correspondingly provided on both sides of the mold platform. The bearings are protruding relative to the mold table surface of the mold platform, and are used for allowing the side support strips to move on the bearings, thereby allowing the movable steel plate to move on the mold platform, and the mold table surface is used to place the movable steel plate.

[0012] Furthermore, the side support strip is provided with a plurality of arc notches, and the arc notches match the position and shape of the bearing, so that when the arc notches correspond to the position of the bearing, the movable steel plate fits the mold platform.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides an automatic pop-up and locking device for a movable steel plate, which is used for automatically popping out and locking the movable steel plate 2 on the mold platform 1. The device includes a translation drive mechanism, a slider 6, a slide groove 7, a connecting rod 8, a lock hook swing arm 9, a shaft seat 10 and a fixed plate 11. The translation drive structure, the slide groove 7 and the shaft seat 10 are all fixedly connected to the mold platform 1, and the fixed plate 11 is fixedly connected to the movable steel plate 2. The output end of the translation drive structure, the slider 6, the connecting rod 8 and the lock hook swing arm 9 are connected in sequence. The slide groove 7 is connected to the slider 6 for allowing the slider 6 to move. The lock hook swing arm 9 is rotatably connected to the shaft seat 10. The lock hook swing arm 9 is provided with a groove, and the fixed plate 11 is located in the groove. The two ends of the groove are respectively provided with a first protrusion and a second protrusion. The first protrusion is used to hook out the fixed plate, and the second protrusion is used to resist the fixed plate.

[0029] When in use, when the translation drive mechanism is extended, the slider 6 is extended accordingly, and drives the lock hook swing arm 9 to rotate clockwise on the shaft seat 10 through the connecting rod 8, so that the first protrusion hooks out the fixed plate 11, thereby popping out the movable steel plate 2;

[0030] When the translation drive mechanism contracts, the slider 6 contracts accordingly, and drives the lock hook swing arm 9 to rotate counterclockwise on the shaft seat 10 through the connecting rod 8, so that the second protrusion abuts against the fixed plate 11, thereby locking the movable steel plate 2.

[0031] The various components and operating principles of the device are described in detail below.

[0032] 1. Translation drive mechanism

[0033] The translation driving mechanism comprises a cylinder 5 and a cylinder fixing seat 3 . The cylinder fixing seat 3 is installed on the mold platform 1 and fixedly connected to the cylinder 5 . The output end of the cylinder 5 is connected to the slider 6 .

[0034] The translation drive mechanism further includes a cylinder magnetic induction switch 4 , which is fixedly connected to the cylinder 5 and is used to detect the position of the piston rod in the cylinder 5 .

[0035] In this embodiment, the cylinder fixing seat 3 is fixedly connected to the mold platform 1 by bolts, and the cylinder magnetic induction switch 4 is connected to the cylinder 5 by an elastic clip.

[0036] The device also includes a controller, which is connected to the cylinder 5 and the cylinder magnetic induction switch 4 respectively.

[0037] 2. Slider 6

[0038] The shape and size of the slide groove 7 match those of the slide block 6 and are used to limit the radial displacement of the slide block 6 .

[0039] In this embodiment, the slide block 6 is a rectangular parallelepiped structure. The slide slot 7 is fixedly connected to the mold platform 1 by bolts.

[0040] 3. Other settings

[0041] like Figure 3 As shown, side support bars 13 are provided on both sides of the movable steel plate 2, and multiple bearings 12 are correspondingly provided on both sides of the mold platform 1. The top of the bearing 12 is higher than the mold surface of the mold platform 1, that is, the bearing 12 is raised relative to the mold surface of the mold platform 1, and is used for the side support bars 13 to move on the bearing 12, thereby allowing the movable steel plate 2 to move on the mold platform 1, and the mold surface is used to place the movable steel plate 2.

[0042] The side support strip 13 is provided with a plurality of arc notches, which match the position and shape of the arc notches with the bearing 12, so that when the arc notches correspond to the positions of the bearing 12, the movable steel plate 2 fits the die table 1. The arc surface size of the arc notches does not exceed one quarter of the outer circumference of the bearing 12.

[0043] A plurality of bearings 12 are evenly distributed on both sides of the mold platform 1 .

[0044] In this embodiment, three bearings 12 are respectively arranged on two opposite sides of the mold platform 1 .

[0045] 4. Action principle

[0046] The cylinder 5 is fixed on the die table 1 (the lower die table in this embodiment) by the cylinder fixing seat 3. The cylinder magnetic induction switch 4 is installed on the cylinder 5 to detect the position of the cylinder piston rod. The slider 6 is installed at the front end of the cylinder piston rod. The slide groove 7 is installed on the die table 1, and the slider 6 can only slide left and right in the slide groove 7. The slide groove 7 is used to eliminate the radial force on the cylinder 5. The rotating shaft seat 10 is fixed on the die table 1, and the lock hook swing arm 9 is installed on the rotating shaft seat 10 and can rotate. The connecting rod 8 connects the lock hook swing arm 9 with the slider 6. The fixed plate 11 is installed at the front end of the movable steel plate 2, and the side support strips 13 are installed on both sides of the movable steel plate 2. Six bearings 12 are installed on both sides of the die table 1, and the side support strips 13 can move on it.

[0047] When the cylinder 5 is ventilated, the cylinder piston rod extends, and drives the lock hook swing arm 9 to rotate clockwise around the rotating shaft seat 10 through the slider 6 and the connecting rod 8. The lock hook swing arm 9 will hook the fixed plate 11 outwards, and the movable steel plate will move outward as a whole. Figure 3 When the arc notches on the bottom surfaces of the support strips 13 on both sides of the movable steel plate pass over the bearings 12 at different distribution positions, the bottom surface of the movable steel plate 2 will be separated from the upper plane of the die table 1 by a distance, which is equivalent to a number of bearings 12 supporting the movable steel plate 2 as a whole. At this time, the movable steel plate 2 can be flexibly moved in and out on the bearings 12. Even if the movable steel plate 2 is very heavy, it can be easily moved on the bearings 12.

[0048] When the cylinder 5 is back-ventilated, the cylinder piston rod retracts, and the lock hook swing arm 9 rotates counterclockwise, which will press the fixed plate 11, and then lock the movable steel plate 2. At this time, the arc notches at the bottom of the supporting strips 13 on both sides of the movable steel plate just avoid the supported bearings 12, and the bottom surface of the movable steel plate 2 will fit with the upper plane of the die table 1, and will be pressed when used for die cutting and creasing. At the same time, the cylinder magnetic induction switch 4 will detect the position of the cylinder piston rod in real time to ensure that the movable steel plate 2 is always in a locked state when the machine is working.

[0049] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
