Description

Technical Field

[0001] This utility model belongs to the technical field of printing product processing equipment, specifically relating to a high-pressure punching device for printing products. Background Technology

[0002] In the production process of printed products, punching is often required to facilitate subsequent processes. However, existing punching devices for printed products have some shortcomings. On the one hand, for multiple stacked printed products, the pressure of ordinary punching devices is insufficient, resulting in poor punching effects and problems such as uneven hole edges and incomplete penetration. On the other hand, existing punching devices are difficult to adjust the initial positioning position of printed products according to different specifications and requirements, resulting in poor versatility and difficulty in meeting the needs of small-batch, multi-specification production.

[0003] Therefore, there is an urgent need for a high-pressure punching device for printed products that can provide strong pressure and flexibly adjust the product positioning. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high-pressure punching device for printed products, which solves the problems of insufficient pressure and poor versatility of the punching devices for printed products in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-pressure punching device for printed products, including a quick clamp, a base plate and a top plate suspended above the base plate, a booster cylinder is provided on the top plate, a punching die is detachably connected to the base plate, and a punching cutter that matches the punching die and can be pressed vertically downward toward the punching die is detachably connected to the output end of the booster cylinder;

[0006] The base plate is slidably connected with a first baffle and a second baffle in the horizontal direction. The limiting surfaces on the first baffle and the second baffle for blocking the product are perpendicular to each other. The moving directions of the first baffle and the second baffle are perpendicular to each other, and the moving direction of the first baffle is perpendicular to its limiting surface. The output end of the quick clamp can press down the first baffle and the second baffle so that they are tightly against the base plate.

[0007] Optionally, the first baffle and the second baffle are T-shaped, and the output end of the quick clamp can press down on the top side of the support leg on the first baffle and the second baffle, which is perpendicular to its limiting surface;

[0008] The quick clamp is positioned outside the vertical projection range of the top plate.

[0009] Optionally, the base plate is provided with multiple sets of limiting grooves along the moving direction of the first baffle and the second baffle, and the bottom of the first baffle and the second baffle is provided with limiting ribs that cooperate with the limiting grooves.

[0010] Optionally, the base plate is provided with multiple sets of scale lines along the moving direction of the first baffle and the second baffle.

[0011] Optionally, a plurality of parallel support shafts are provided between the top plate and the bottom plate, and the central axis of the support shafts is parallel to the moving direction of the output end of the booster cylinder.

[0012] Optionally, the output end of the quick clamp is provided with a rubber post that can abut against the surfaces of the first baffle and the second baffle.

[0013] Optionally, the base plate is provided with a recessed groove for embedding the lower punch die, and the lower punch die is provided with a bolt that can be threaded to the bottom side of the recessed groove. When the lower punch die is embedded in the recessed groove, the upper surface of the lower punch die and the upper surface of the base plate are at the same horizontal plane.

[0014] Optionally, the outer periphery of the output end of the booster cylinder is provided with an external thread or an internal thread that can be threadedly connected to the punching tool.

[0015] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: A first and second baffle, which can slide horizontally on the base plate and whose moving directions are perpendicular to each other, and whose limiting surfaces are also perpendicular to each other, precisely position the printed product placed on the base plate. The pressurization characteristics of the booster cylinder are used to complete the high-quality punching operation of the printed product. Furthermore, after punching the same batch of printed products, the positions of the first and second baffles can be quickly adjusted according to the product specifications. The positions of the first and second baffles on the base plate can be quickly and safely fixed using a quick clamp, thereby meeting the precise positioning requirements of products with different specifications and improving the flexibility and positioning accuracy of the punching device.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] like Figure 1As shown, a high-pressure punching device for printed products includes a quick clamp 1, a base plate 2, and a top plate 3 suspended above the base plate 2. A booster cylinder 4 is mounted on the top plate 3. Both the booster cylinder 4 and the quick clamp 1 are existing technologies. The booster cylinder 4 is electrically connected to a piston cylinder, a booster tank (air storage tank), and a control valve, among other components, and can convert low-pressure gas (the power source) into high-pressure gas, thereby enabling the piston cylinder's output end to obtain greater output force and speed during operation. The quick clamp 1 mainly consists of a chuck, a linkage mechanism, and a handle. The operator can drive the chuck to rotate or extend by controlling the handle. Furthermore, a punching die 5 is detachably connected to the base plate 2, and a punching tool 6, matching the punching die 5 and capable of vertically pressing down towards the punching die 5, is detachably connected to the output end of the booster cylinder 4. Both the punching cutter 6 and the punching die 5 are existing technologies. The punching cutter 6 and the punching die 5 work together, and driven by the booster cylinder 4, they can punch multiple printed products stacked on the base plate 2. Because the booster cylinder 4 has a strong output effect, the punching device in this technical solution can effectively avoid problems such as uneven punching edges and incomplete penetration during the punching process. Simultaneously, in this technical solution, a first baffle 7 and a second baffle 8 are slidably connected to the base plate 2 in the horizontal direction. The limiting surfaces 78 on the first baffle 7 and the second baffle 8, used to block products, are perpendicular to each other. The moving directions of the first baffle 7 and the second baffle 8 are perpendicular to each other, and the moving direction of the first baffle 7 is perpendicular to its limiting surface 78. This allows the technical solution to adjust the distance between the limiting surfaces 78 on the first baffle 7 and the second baffle 8 and the punching die 5 by moving the positions of the first baffle 7 and the second baffle 8 on the base plate 2, thereby meeting the positioning requirements of products of different specifications. At the same time, the output end of the quick clamp 1 can press down the first baffle 7 and the second baffle 8 to fit tightly against the base plate 2, so that the first baffle 7 and the second baffle 8 can be quickly fixed by operating the quick clamp 1 after the position has been adjusted.

[0022] The punching die 5, which is detachably connected to the base plate 2 as described above, is specifically as follows: Figure 1 As shown, the base plate 2 has a recessed groove (not shown) for embedding the lower punch die 5, and a bolt (not shown) passes through the lower punch die 5 and can be threaded to the bottom of the recessed groove. When the lower punch die 5 is embedded in the recessed groove, the upper surface of the lower punch die 5 and the upper surface of the base plate 2 are at the same level. By loosening the bolt that passes through the lower punch die 5 and is threaded to the bottom of the recessed groove, the lower punch die 5 can be easily removed from the base plate 2, so that the operator can replace different types of lower punch dies 5 according to the needs of use, improving the flexibility of the punching device. Similarly, the punching tool 6, which is detachably connected to the output end of the booster cylinder 4, can also be flexibly disassembled and replaced according to the needs of use. Specifically, as shown... Figure 1 As shown, the outer periphery of the output end of the booster cylinder 4 is provided with an external thread (not shown in the figure) or an internal thread (not shown in the figure) that can be threadedly connected to the punching tool 6.

[0023] Furthermore, the output end of the quick clamp 1 is provided with a rubber post 101 that can abut against the surfaces of the first baffle 7 and the second baffle 8 to increase the friction when the output end of the quick clamp 1 contacts the first baffle 7 and the second baffle 8. At the same time, it can also prevent the output end of the quick clamp 1 from rigidly contacting the first baffle 7 and the second baffle 8, thus affecting the positioning accuracy of the first baffle 7 and the second baffle 8.

[0024] Furthermore, in this technical solution, such as Figure 1 As shown, the first baffle 7 and the second baffle 8 are T-shaped, and the output end of the quick clamp 1 can press down on the top side of the support leg 7801 on the first baffle 7 and the second baffle 8, which is perpendicular to its limiting surface 78. The quick clamp 1 is positioned outside the vertical projection range of the top plate 3, which facilitates operation by the operator and effectively prevents the operator from accidentally entering the working area of ​​the punching device while operating the quick clamp 1, thus improving the safety of the operator.

[0025] Furthermore, such as Figure 1 As shown, multiple sets of limiting grooves 201 are respectively provided on the base plate 2 along the moving direction of the first baffle 7 and the second baffle 8, and the bottom of the first baffle 7 and the second baffle 8 are respectively provided with limiting ribs 7802 that cooperate with the limiting grooves 201. The limiting ribs 7802 on the first baffle 7 and the second baffle 8 can be movably embedded in the limiting grooves 201 on the base plate 2, so that the first baffle 7 and the second baffle 8 can move linearly along the corresponding limiting grooves 201, which is convenient for operators to operate.

[0026] The above description is provided to facilitate operators' intuitive understanding of the straight-line distances between the first baffle 7, the second baffle 8, and the lower punch die 5. Figure 1 As shown, multiple sets of scale lines 202 are provided on the base plate 2 along the moving direction of the first baffle 7 and the second baffle 8.

[0027] In this embodiment, multiple parallel support shafts 9 are arranged between the top plate 3 and the bottom plate 2. The two ends of each support shaft 9 can be embedded in the top plate 3 and the bottom plate 2 respectively, and are fixedly connected to the top plate 3 and the bottom plate 2 respectively by bolts passing through them, thus ensuring the strength of the entire structure. It should be noted that the central axis of the support shaft 9 is parallel to the direction of movement of the output end of the booster cylinder 4. This ensures that when the booster cylinder 4 drives the punching tool 6 to punch the printed product placed on the bottom plate 2, the support shaft 9 is only subjected to a reaction force acting along its axial direction, thereby preventing bending and deformation of the support shaft 9, ensuring structural stability, and improving the service life of the device.

[0028] Working Principle: The printed products placed on the base plate 2 are precisely positioned by the first baffle 7 and the second baffle 8, which can slide horizontally and move perpendicularly to each other, and whose limiting surfaces 78 are also perpendicular to each other. Then, the quick clamp 1 is used to fix the position of the first baffle 7 and the second baffle 8. After the operator places several stacked printed products on the base plate 2 and completes the positioning by the first baffle 7 and the second baffle 8, the pressure cylinder 4 on the top plate 3 is activated. Its output end drives the punching cutter 6, which matches the punching die 5, to press down vertically. The pressure increase characteristic of the pressure cylinder 4 completes the punching of the product. After the pressure cylinder 4 resets, the punched printed product is removed, and the next operation of products of the same specification can be carried out. After the punching operation of the same batch of printed products is completed, the position of the first baffle 7 and the second baffle 8 can be quickly adjusted according to the specifications of the products, thereby meeting the needs of precise positioning of products of different specifications and improving the flexibility and positioning accuracy of the punching device.

[0029] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
