Technical Field
[0001] The utility model relates to the field of die-cutting equipment, in particular to an automatic die-cutting advance and retreat device. Background Art
[0002] The working principle of die cutting is to use a die cutter, a steel knife, and a metal mold to apply a certain pressure to the mold to cut the product into a certain shape. Among them, the mold is the key to product formation. Specifically, the raw materials of the product, such as steel strips and plates, pass through the mold continuously, and the die cutter cuts the raw materials on the mold to obtain the target product.
[0003] In the prior art, the die cutter is directly driven by a cylinder, and the stroke of the die cutter is equal to the stroke of the cylinder. When the size of the equipment is small, the stroke of the cylinder can only be set too small, which is easy to cause misoperation, that is, the die cutter does not have enough reset distance and scratches the product.

[0015] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.
[0016] like Figure 1 As shown, a die-cutting automatic advance and retract device includes a frame 1 and two positioning columns 2 arranged in the frame 1, and the two positioning columns 2 are sequentially provided with a first positioning plate 3, a second positioning plate 4 and a third positioning plate 5 that can slide freely, the first positioning plate 3 is connected to a cylinder, and the first positioning plate 3 and the second positioning plate 4 are respectively provided with a bottom die 7 and a cutting die 8 on the sides facing each other, the two ends of the first positioning plate 3 are respectively rotatably connected to one end of a first crank 9, the two ends of the third positioning plate 5 are respectively rotatably connected to one end of a second crank 10, the other ends of the first crank 9 and the second crank 10 are respectively rotatably connected to the two ends of a rotating plate 11, the middle part of the rotating plate 11 is rotatably connected to the frame 1, and the third positioning plate 5 is elastically connected to the second positioning plate 4.
[0017] A limiting post 12 is provided between the second positioning plate 4 and the third positioning plate 5, and the limiting post 12 is fixedly connected to only one of the second positioning plate 4 or the third positioning plate 5. A spring 13 is provided between the second positioning plate 4 and the third positioning plate 5. A cutting knife 14 is provided in the cutting die 8, and the two ends of the cutting knife 14 are respectively connected to connecting posts 6, which pass through the second positioning plate 4 and are fixedly connected to the third positioning plate 5.
[0018] Working principle:
[0019] by Figure 1For example, when the cylinder contracts, it drives the first positioning plate 3 to move right, and the first crank 9 pulls the rotating plate 11 to rotate clockwise, so that the second crank 10 pushes the third positioning plate 5 to move left, and the third positioning plate 5 elastically drives the second positioning plate 4 to move left, and the cutting die 8 and the bottom die 7 are separated. When the cylinder extends, it drives the first positioning plate 3 to move left, and similarly, the third positioning plate 5 moves right. At this time, the cutting die 8 and the bottom die 7 are close. After the two are in contact, the first positioning plate 3 and the second positioning plate 4 move slightly to the left as a whole, but the third positioning plate 5 is elastically connected to the second positioning plate 4, so it will continue to drive the connecting column 6 to move right, and the cutter 14 presses against the bottom die 7, so that the product between the bottom die 7 and the cutting die 8 is cut, until the limit column 12 contacts the second positioning plate 4 and the third positioning plate 5 respectively and stops moving.
[0020] Beneficial effects:
[0021] Based on the set first crank 9, second crank 10 and rotating plate 11, when the first positioning plate 3 is driven to move, the second positioning plate 4 and the third positioning plate 5 will also move accordingly to realize the opening and closing of the cutting die 8 and the base plate, and the opening and closing distance between the cutting die 8 and the base plate is equal to twice the cylinder stroke.
[0022] Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present disclosure can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be widely interpreted within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
