Description

Technical Field

[0001] The present invention relates to the technical field of die-cutting equipment, and particularly to an automated die-cutting equipment for mechanical manufacturing. Background Art

[0002] Die-cutting is a special cutting process. By using a specially made cutting tool with a specific shape, a pre-designed pattern can be cut out on the processed material. It can be used to process materials such as paper, plastic, rubber, and metal strips, and is widely used in multiple industries such as printing, packaging, electronic appliances, and automobiles.

[0003] In the printing and packaging industries, the processing objects of die-cutting equipment are mostly paper products. While in the fields of mechanical processing and manufacturing such as electronic appliances and automobiles, the die-cutting objects may be rubber, plastic, or even metal. Compared with paper products, these materials have greater hardness, toughness, and higher comprehensive strength, and are more laborious to die-cut.

[0004] Die-cutting itself has no difference in principle from cutting other objects in life. Combining life experience, it can be known that when cutting other objects in life, in addition to applying pressure to the object to be cut, the cutting tool can also move horizontally back and forth to apply frictional force to the object. For example, when cutting vegetables in life, this will be more labor-saving and will cut the object more smoothly.

[0005] However, in the prior art, the cutting tool of die-cutting equipment is not in the shape of a long strip like an ordinary cutting tool in life, but is special or even irregular. Therefore, the cutting tool of die-cutting equipment moves back and forth along a straight line and cannot apply lateral frictional force to the material to be cut, making it more laborious when die-cutting materials with higher strength. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide an automated die-cutting equipment for mechanical manufacturing to solve the problem that it is more laborious in the prior art when die-cutting materials with higher strength.

Detailed implementation manners

Obviously, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0037] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side" and "the other side" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0039] In addition, terms such as "the same" do not mean that the components are required to be absolutely the same, but there may be slight differences. The term "vertical" only means that the positional relationship between components is relatively more vertical compared to "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0040] Please refer to Figures 1-11 , the present invention provides a technical solution: an automated die-cutting device for mechanical manufacturing, including a workbench 1. Two mounting blocks 5 are provided on the top of the workbench 1. A detachable fixing plate 8 is provided at the bottom of the mounting block 5. A die-cutting knife 802 is fixedly provided at the bottom of the left fixing plate 8, and a plurality of pins 801 are fixedly provided at the bottom of the right fixing plate 8;

[0041] The pins 801 are arranged in the same pattern as the die-cutting knife 802. The bottom edge of the die-cutting knife 802 is composed of a plurality of tip protrusions 803. Therefore, the bottom of the die-cutting knife 802 is in an uneven serrated shape. The tip protrusions 803 are in an inverted right-angled triangle shape. The tip protrusions 803 correspond to the pins 801 one by one. The fixing plate 8 can be detachably separated from the mounting block 5 to facilitate changing the die-cutting pattern.

[0042] Move the raw material to be die-cut below the mounting block 5. First, the right mounting block 5 drives the fixing plate 8 at its bottom to move downward and apply a downward pressure to the raw material. Under the action of the downward pressure, the pins 801 puncture a plurality of small holes in the raw material. The small holes are arranged in a corresponding pattern on the raw material. Subsequently, the material moves again so that the part punctured by the pins 801 moves directly below the left mounting block 5, and the punctured small holes are aligned vertically with the tip protrusions 803 one by one. After the left mounting block 5 moves downward, the die-cutting knife 802 and the tip protrusions 803 move downward and apply pressure to the raw material. The tips of the tip protrusions 803 are aligned with the corresponding small holes. As the tip protrusions 803 move downward, the inclined sides on both sides of the tip protrusions 803 will contact and cut the hole walls until all the small holes are connected by cutting, and the raw material is thus completely cut off, thereby cutting out a corresponding shaped pattern from the raw material;

[0043] Since the two sides of the tip projection 803 are inclined, a horizontal frictional force will be generated on the raw material during its vertical downward movement and cutting of the raw material. Combining with common sense in life, even for a high-precision cutting tool, the cutting edge part is uneven after magnification. Therefore, the friction between the cutting edge and the material to be cut in the horizontal direction plays a role similar to that of a saw, enabling smoother cutting and saving more effort. This is also the reason why horizontal back-and-forth sliding is often required when using a cutting tool to cut an object in life. The tip projection 803 of the present invention generates a frictional force in the horizontal direction with the raw material to be die-cut, playing the same role, making the die-cutting smoother and more labor-saving, and being more suitable for die-cutting high-strength materials in the field of mechanical manufacturing;

[0044] In addition, before the die-cutting knife 802 and the tip projection 803 perform die-cutting, the raw material is perforated by the pin 801. The small holes punched are all located at the fracture part of the die-cutting. Therefore, the perforation of the pin 801 can be regarded as the first die-cutting, but the raw material is not completely cut off. Instead, the connection strength between the materials is reduced in the form of perforation. The second die-cutting by the die-cutting knife 802 and the tip projection 803 will completely cut off the raw material. In this way, die-cutting is carried out in two steps before and after, and the raw material is cut off in two steps, further achieving the purpose of saving effort, especially suitable for die-cutting high-strength materials in the field of mechanical manufacturing.

[0045] In this embodiment, a cushion block 9 and a template 11 are provided at the top of the workbench 1. The cushion block 9 is directly below the right fixing plate 8, and the template 11 is directly below the left fixing plate 8. A through groove with the same shape as the pattern of the die-cutting knife 802 is opened on the template 11. A support frame 1101 is provided at the bottom of the template 11, and the support frame 1101 is fixed to the top of the workbench 1. A rubber block 901 is inlaid on the cushion block 9, and the tops of the template 11, the cushion block 9 and the rubber block 901 are flush.

[0046] When the installation block 5 on the right perforates the raw material, the raw material is placed on the tops of the cushion block 9 and the rubber block 901. The downward-moving pin 801 pierces the raw material and also pierces into the rubber block 901 downward, which does not affect the perforation and also provides support for the raw material during perforation. When the die-cutting knife 802 and the tip projection 803 perform die-cutting, the template 11 is placed at the bottom of the raw material to support the raw material. After the die-cutting knife 802 and the tip projection 803 move downward, they pass through the raw material and cut it off, and the die-cutting knife 802 is closely embedded in the through groove along the edge position of the through groove, so as to push the cut part into the through groove.

[0047] In this embodiment, a collection box 2 is fixedly provided at the bottom end of the workbench 1. A communication port 101 is opened on the workbench 1. The collection box 2 communicates with the support frame 1101 through the communication port 101. A base 3 is fixedly provided at the bottom end of the collection box 2. Two closed doors are movably connected to the front side of the collection box 2 through hinges. An exhaust fan 201 is fixedly provided on the outer vertical surface of the collection box 2. The exhaust fan 201 can be selected from the LH-DFJ-B03 series exhaust fans.

[0048] During die-cutting, the exhaust fan 201 operates and extracts the air in the collection box 2, generating negative pressure inside the collection box 2. Then, the parts die-cut from the raw material are inhaled into the collection box 2 through the support frame 1101 and the communication port 101 at the through groove for collection. After all die-cutting work is completed, the closed doors can be opened to collect these die-cut parts.

[0049] In this embodiment, two driving components 4 are provided at the top end of the workbench 1. The template 11 and the cushion block 9 are located between the two driving components 4. The driving components 4 can drive the die-cutting material to move from right to left. The driving component 4 includes a bracket 401 provided at the top end of the workbench 1. Two central shafts 402 are rotatably connected to the inner wall of the bracket 401;

[0050] Gears 405 are fixedly provided at the outer ends of the two central shafts 402. The two gears 405 are meshed with each other. Rubber rollers 403 are fixedly provided at the outer ends of the central shafts 402. The die-cutting material is clamped between the two rubber rollers 403. A driving motor 404 for driving one of the central shafts 402 to rotate is fixedly provided on the front side of the bracket 401. The driving motor 404 can be selected from the YVP series motors.

[0051] The raw material to be die-cut is generally wound into a long strip. Pull out one end of it, make it pass through the two rubber rollers 403 of the right driving component 4 first, and then pass through the two rubber rollers 403 of the left driving component 4. And the raw material is in a straightened state between the two driving components 4. During die-cutting, turn on the driving motor 404. The driving motors 404 of the two driving components 4 rotate at the same speed. The driving motor 404 drives the central shaft 402 to rotate. The central shaft 402 drives the gear 405. The two gears 405 are meshed. Therefore, the two central shafts 402 of the driving component 4 rotate synchronously, and the two rubber rollers 403 also rotate synchronously, pulling the raw material clamped therein to move, so as to realize the continuous and automatic movement of the raw material, and further realize automatic die-cutting. The moving distance and speed of the raw material can be adjusted by itself;

[0052] When the two mounting blocks 5 perform die-cutting, the driving component 4 pauses operation, enabling the raw material to be die-cut in a stationary state. After the die-cutting is completed, the raw material continues to move. Each die-cutting takes 5 seconds. Therefore, for each die-cutting, the driving component 4 will pause for 5 seconds, and the distance that the raw material moves under the drive of the driving component 4 each time is also preset to ensure that the raw material after perforation can accurately move under the die-cutting blade 802, aligning the tip protrusions 803 with the holes on the raw material one by one, so that the die-cutting blade 802 can perform die-cutting again.

[0053] In this embodiment, support blocks 10 are provided on the front and rear sides of both the spacer block 9 and the template 11. The support blocks 10 are detachably provided on the top of the workbench 1. The top of the support blocks 10 is flush with the top of the spacer block 9 and the top of the template 11. The width of the die-cutting material is slightly larger than the widths of the spacer block 9 and the template 11. Pressing components 7 are provided on the front and rear sides of both mounting blocks 5. The pressing components 7 correspond to the support blocks 10 one by one, and the support blocks 10 are located directly below the corresponding pressing components 7.

[0054] During the movement of the raw material, its bottom contacts the tops of the template 11 and the spacer block 9, and the edge positions on the front and rear sides of the raw material respectively rest on the tops of the support blocks 10 on the front and rear sides. The pressing component 7 presses the edge positions of the raw material against the tops of the support blocks 10 as the mounting block 5 presses down, preventing the raw material from shifting during die-cutting.

[0055] In this embodiment, the pressing component 7 includes a side plate 701 provided on the outer end of the mounting block 5 through bolts. A pressing plate 704 is provided at the bottom of the side plate 701. Two springs 703 are provided between the pressing plate 704 and the side plate 701. A U-shaped rod 702 penetrating the side plate 701 is provided on the side plate 701. Both ends of the U-shaped rod 702 are fixedly connected to the top of the pressing plate 704. The two springs 703 are respectively sleeved on the outer sides of both ends of the U-shaped rod 702, and both ends of the springs 703 are fixedly connected to the side plate 701 and the pressing plate 704 respectively.

[0056] During die-cutting, the pressing component 7 can move downward with the mounting block 5. The position of the pressing plate 704 is lower than that of the mounting block 5 and the fixing plate 8, so it first contacts the material and presses on the top of the material. Subsequently, the mounting block 5 continues to move downward, driving the side plate 701 to move downward. The side plate 701 slides along the U-shaped rod 702 and compresses the spring 703, causing the spring 703 to be compressed. The spring 703 thus generates an elastic force and pushes the pressing plate 704 downward, pressing the raw material tightly against the top of the support block 10. After the die-cutting is completed, the mounting block 5 moves upward, driving the entire pressing component 7 to move upward, thereby releasing the fixation of the raw material.

[0057] In this embodiment, two lifting components 6 are provided at the rear side of the workbench 1. The lifting component 6 includes a bottom plate 602 fixedly connected to the rear edge of the base 3. A column 601 is fixedly provided at the top of the bottom plate 602, and a sliding seat 604 capable of sliding up and down is sleeved on the outer end of the column 601.

[0058] The two lifting components 6 are respectively used to drive the two mounting blocks 5 to operate. The mounting blocks 5 are connected to the sliding seats 604 of the corresponding lifting components 6. By driving the sliding seats 604 to move up and down along the bottom plate 602, the mounting blocks 5 are driven to move up and down, so as to perform die cutting.

[0059] In this embodiment, a hydraulic cylinder 603 is provided at the top of the bottom plate 602 and located at the rear side of the column 601. The top of the hydraulic cylinder 603 is detachably connected to the sliding seat 604. The hydraulic cylinder 603 can be selected from the HSG series of hydraulic cylinders for industrial machinery. A connecting arm 605 is fixedly provided on the front side of the sliding seat 604. The front ends of the connecting arms 605 of the two lifting components 6 are respectively detachably connected to the tops of the two mounting blocks 5.

[0060] The corresponding mounting block 5 is connected to the front side of the sliding seat 604 through the connecting arm 605. The expansion and contraction of the hydraulic cylinder 603 controls the up and down sliding of the sliding seat 604, and further controls the up and down movement of the mounting block 5, so as to perform die cutting. The hydraulic cylinder 603 provides the pressure required for die cutting.

[0061] Working principle: The raw materials for die cutting are clamped on the driving components 4, and the two driving components 4 drive the raw materials to move for automatic feeding. The moving raw materials are first die cut for the first time by the mounting block 5 and the fixing plate 8 on the right side to punch holes on the surface of the raw materials. Then the raw materials continue to move to the lower part of the mounting block 5 on the left side. The mounting block 5 and the fixing plate 8 on the left side move down and perform die cutting for the second time. Corresponding patterns are cut out on the raw materials through two die cuttings successively. The raw materials continue to run, and the above operations are repeated to perform die cutting continuously and automatically. The whole process is controlled by a pre-set program, and the automated die cutting equipment and related programs are all mature existing technologies, so no more details will be given.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
