Description

Technical Field

[0001] The utility model relates to the technical field of corrugated board processing, in particular to a metal corrugated board forming device. Background Art

[0002] In the field of stainless steel corrugated board forming, roller forming is a common technical means. Taking the roller forming of stainless steel honeycomb inclined tube corrugated board for water treatment as an example, it uses a rolling forming wheel set composed of multiple pairs of upper and lower rollers with complementary concave and convex shapes. The plate is formed by gradually deepening the rolling deformation through each roller. First, the center wave of the plate width is rolled by the first roller, and then the corrugations are symmetrically rolled from the center to both sides in sequence. During the forming process, the two unformed sides are in a free state, and at least one more pass is maintained for shaping after each wave is formed.

[0003] The roller forming technology has the following disadvantages:

[0004] 1) The equipment structure is complex: Roller forming requires a rolling forming wheel set composed of multiple pairs of upper and lower rollers with complementary concave and convex shapes. The arrangement and coordinated operation between each wheel set are relatively complex, resulting in a large and cumbersome overall structure of the equipment. This not only increases the manufacturing difficulty and cost of the equipment, but also makes the maintenance and debugging work of the equipment more difficult, reducing the production stability and reliability.

[0005] 2) It cannot use thinner materials: Due to the bending and extrusion methods of the plate during the roller forming process, thinner materials are prone to problems such as uneven deformation and cracking during the forming process, which cannot guarantee the forming quality. Therefore, the use of thin materials is restricted, increasing the raw material cost, and it also cannot meet some application scenarios with requirements for thin and light materials.

[0006] 3) The mold cost is high: The mold for roller forming consists of multiple groups of rollers, and these rollers need to be processed and manufactured with high precision to ensure the accuracy of the forming dimensions. Moreover, in order to meet different size requirements such as wave height and wave pitch, multiple sets of rollers with different specifications need to be equipped, further increasing the manufacturing cost of the mold.

[0007] 4) Difficult to change dimensions: When corrugated boards of different sizes need to be produced, the roller forming equipment needs to replace a large number of roller sets. The replacement process is cumbersome and requires professional personnel for debugging and installation, consuming a large amount of time and labor costs. This makes a device often limited to producing corrugated boards of one size in actual production, unable to quickly adapt to the diverse market demands, and reducing the production efficiency and economic benefits of the equipment.

[0008] 5) The shape of the corrugated board is produced along the feeding direction, and the cutting process is difficult. The cutting tool needs to match the cutting shape, and different sizes of corrugated boards require different sizes of cutting tools. Content of the Utility Model

[0009] The purpose of the present utility model is to provide a metal corrugated board forming device to solve the problems existing in the above-mentioned prior art, which can simplify the device structure, reduce the manufacturing and maintenance costs of the device; can use thinner stainless steel materials to reduce the raw material costs; reduce the mold costs and improve the universality of the molds.

[0017] Preferably, a resilient spring is embedded inside the lower mold. A pushing block is arranged at the top of the resilient spring. An adaptation hole for the pushing block to extend or retract is arranged on the lower mold. When the resilient spring is in its original state, the pushing block extends out of the interior of the lower mold. When the upper mold and the lower mold are closed, the pushing block is compressed back into the lower mold. When the upper mold and the lower mold are opened, the pushing block rebounds under the action of the resilient spring and pushes out the corrugated board formed by pressing from the mold groove of the lower mold.

[0018] Preferably, a finished product platform is arranged at the rear of the main machine frame. The cutting device is arranged at the front end of the finished product platform. The cutting device includes a cutting support and a laser cutting module, and the laser cutting module is supported by the cutting support.

Compared with the complex structure of at least more than a dozen roller forming stations in traditional roller forming, the length and floor area of this equipment are smaller, the failure rate is lower, and the maintenance is more rapid and convenient. This not only reduces the manufacturing and maintenance costs of the equipment, but also improves the stability and reliability of production.

[0023] 2) The utility model can accurately design the geometric shapes of the upper and lower molds to ensure the forming springback coefficient, enabling thin materials to be well formed and enabling corrugated boards to be formed using thinner stainless steel materials.

[0024] 3) Due to the action mode of the mold forming on the sheet material, the thin material can be uniformly stressed during the forming process, avoiding problems such as uneven deformation and cracking that are prone to occur in roll forming, and ensuring the forming quality.

[0042] The purpose of the present invention is to provide a metal corrugated board forming device to solve the problems existing in the prior art.

[0043] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0044] The metal corrugated board forming device in this embodiment, as Figures 1-3 shown, includes a raw material conveying device 1, a material pressing and feeding device 2, a forming device 3 and a cutting device 4.

The material pressing and feeding device 2 includes conveying rollers arranged oppositely up and down. The board passes between the conveying rollers and is conveyed to the forming device 3. The forming device 3 includes an upper mold 31 and a lower mold 32 arranged oppositely up and down. The corrugation of the corrugated board is formed on the board through the closing of the upper mold 31 and the lower mold 32. The cutting device 4 is arranged behind the forming device 3 and is used to cut the formed corrugated board semi-finished product. The steel coil feeding device feeds the board on the steel coil 11 into the equipment. The material pressing and feeding device 2 adjusts the feeding speed of the board by adjusting the rotation speed of the conveying rollers, and then adjusts the required feeding distance within a set time, and accurately feeds the material into the forming device 3. The upper mold 31 and the lower mold 32 work together to apply pressure to the board to form it into a corrugated board. The equipment identifies the number of corrugations through the internal detection device. When the number of corrugations meets the requirements, the laser cutting module 42 located at the rear end of the bending mechanism starts to work, and finally the inclined tube corrugated board semi-finished product is obtained. These semi-finished products are then welded according to the product size requirements to form a whole stainless steel corrugated board product.

The mold cavity is adapted to the corrugations of the corrugated board. The two fixed molds 8 can respectively face any two adjacent ones among the multiple corrugations of the corrugated board, and a laser cutting gap is left between the two fixed molds 8 to ensure that the cutting position is consistent each time. After the semi-finished corrugated board after forming is fed in place by the material pressing and feeding device 2, the fixed mold 8 presses down to accurately position the cutting position to fix the corrugated board. The laser cutter cuts the semi-finished corrugated board horizontally along the cutting seam in the middle of the fixed mold 8. After cutting is completed, the laser cutter lifts and resets, and then the fixed mold 8 lifts and resets.
