Description

A corrugated plate forming mold

technical field

The utility model relates to a sheet metal forming die, in particular to a corrugated plate forming die.

Background technique

Mold molding is often used in plate processing, and the processing of corrugated plates is especially common. In the prior art, the processing of corrugated plates is mostly processed by single corrugated continuous stamping, but this processing efficiency is low and the precision is difficult to control. There is a deviation in the distance between the molds. The other mold is one-time stamping, that is, the upper mold and the lower mold are a whole forming mold. Although this forming mold has high efficiency, this mold is only suitable for forming sheets with good plasticity. If this kind of mold is used to process the plate with poor plasticity, the plate will be easily torn. Even if the plate with good plasticity is processed, the plate will be stretched during the processing to make the plate thinner and affect the performance.

Utility model content

In order to solve the deficiencies in the prior art, a corrugated plate forming mold is provided which has high processing efficiency, reduces stretching during plate processing, avoids tearing of plates with poor plasticity during processing, and maintains the thickness of the plate to the greatest extent.

The molding surfaces of two adjacent molding blocks are connected to each other, and an elastic member is provided between the molding blocks and the upper mold base, and a set of upper modules starts from the upper module at the lowest position. The rise is arranged in steps; the upper module at the lowest position first touches the plate through the downward movement of the upper die base, the forming surface and the corrugated surface cooperate to deform the plate through the force exerted by the elastic member, and the upper module deforms the plate in sequence according to the height of the steps.

Finally, the upper die base directly applies force to the upper module to form the sheet.

The waveform of the molding surface is 0.5-1.5 wavelengths.

Two adjacent forming blocks are combined through dovetail grooves.

A limiting block for positioning the plate and capable of movable adjustment is arranged on the lower mold base.

A group of the upper modules rises from the edge position successively and is arranged in steps.

A set of upper modules rises from the central position to both sides successively and is arranged in steps.

The elastic member is a compression spring.

The mold with the above structure, because the upper module on the upper mold base is combined, and the upper module is distributed in steps, so that the molding block at the lowest position first contacts the sheet during the molding process, and the molding block is firstly moved by the elastic force of the elastic piece. The sheet is deformed, and then the adjacent forming blocks contact the sheet, and then contact the sheet in turn for deformation according to the height of the arrangement, so that the extrusion will not cause the entire sheet to be stressed together, thereby reducing the tensile extension and maintaining the thickness of the sheet at the same time It avoids tearing and can meet the processing of plates with poor plasticity; secondly, only one upper and lower die can be closed to realize the processing of a whole corrugated plate, thus improving the processing efficiency.

detailed description

The corrugated plate forming mold shown in Figures 1 to 3 includes: a lower mold base 1 and an upper mold base 2, the lower mold base 1 is provided with a corrugated surface 1-1, and the upper mold base 2 is provided with a set of upper modules 3 , the upper module 3 includes a guide column 3-1 and a molding block 3-2, an installation hole 2-1 and a cavity 2-2 are provided on the upper mold base 2, and the guide column 3-1 is located in the installation hole 2 -1 can move up and down along the mounting hole 2-1. The guide column 3-1 given in this embodiment is not limited to a columnar structure and can also be a traditional structure such as a cuboid that can guide. The column 3-1 slips off from the installation hole 2-1, and the stopper 3-4 is set on the guide column 3-1 to prevent the upper module 3 from falling off from the upper mold base 2. Of course, other conventional means can also be used to guide the slide The column 3-1 acts as a limiter, the forming block 3-2 is arranged at one end of the guide column 3-1, and each forming block 3-2 is provided with a forming surface 3-3 matching the corresponding corrugated surface 1-1 , the forming surface 3-3 cooperates with the corrugated surface 1-1 to deform the plate 6 into a corrugated plate, and the forming surfaces 3-3 of two adjacent forming blocks 3-2 are connected to each other, that is, the adjacent forming surfaces 3-3 are disconnected connected to form a complete corrugated transition, as shown in Figure 4, after all the forming surfaces 3-3 are combined, a complete wavy surface that matches the corrugated surface 1-1 as a whole will be formed. 2 and the upper mold base 2 are provided with an elastic member 4, the elastic member 4 is a compression spring that exerts a certain elastic force on the upper module 3 when the mold is closed so that the sheet can be formed by the cooperation of the forming surface 3-3 and the corrugated surface 1-1 out of shape. In the molding die, the upper modules 3 are arranged in steps, and there is an upper module 3 at the lowest position in a group of upper modules 3, and then the upper modules 3 at the lowest position are arranged in steps in sequence.

From Fig. 1 to Fig. 3, it can be seen that the upper modules 3 of the three embodiments are arranged:

Example 1

As shown in FIG. 1 , the upper module 3 at the lowest position is located at the edge, so these upper modules 3 are sequentially raised from the edge and arranged in steps, and the upper module 3 at the edge on the other side is at the highest position.

Example 2

As shown in Figure 2, the upper module 3 at the central position is located at the lowest position, from the upper module 3 at the central position it rises symmetrically to both sides in a stepped arrangement, and the upper modules 3 at both sides are at the highest position.

Example 3

As shown in Figure 3, any upper module 3 in the middle is at the lowest position, and the upper module 3 at the lowest position rises sequentially to both sides in a step arrangement. Although the two sides are asymmetrical, they are equidistant from the upper module 3 at the lowest position. The modules 3 have the same height (symmetrical and equal heights on both sides are also applicable to Embodiment 2, and the same symmetrical and unequal heights on both sides but arranged in steps are also applicable to Embodiments 2 and 3).

In order to prevent the sheet material 6 from moving and twisting during the forming process, and to ensure accurate positioning when placing the sheet material 6, some limit blocks 5 are set on the edge of the lower mold base 1, and the sheet material 6 is arranged between the limit block blocks 5, passing through the limit block 5 Restricting the movement and twisting of the plate 6, and better positioning when placing the plate 6 on the mold at the same time, in order to adapt to plates 6 of different sizes, the limit block 5 is made adjustable, so that the limit block 5 can be adjusted The distance between them meets the requirements of plates 6 of different sizes. The contact surfaces of two adjacent molding blocks 3-2 are connected by a longitudinal (ie moving direction) dovetail groove.

The forming process is carried out as follows: first, the upper mold base 2 moves downward to drive the upper module 3 to move together, and when the upper module 3 at the lowest position touches the plate 6 placed on the corrugated surface 1-1, the upper mold base 2 still continues Moving downwards, at this time, the elastic member 4 will exert a force on the upper module 3. Since the forming surface 3-3 at this position matches the opposite corrugated surface 1-1, the elastic member 4 exerts force to make the forming surface 3-3 correspond to the corrugated surface 1-1. The corrugated surface 1-1 cooperates to press the plate 6 in the contact part into a corrugation that matches the shape of the forming surface 3-3. When the plate 6 is deformed to a certain extent, the elastic member 4 will be squeezed to keep the upper module 3 in one position. , and the upper module 3 adjacent to the stagnant upper module 3 continues to move downward and deforms the opposite part of the plate 6, and this is done in turn until the last upper module stagnates to complete the processing of the entire plate 6, as shown in the figure As shown in 4, the entire plate 6 is formed into a corrugated plate. In the final stage, the upper mold base 2 actually directly exerts force on all the upper modules 3 to make the plate 6 finally form. During the final force application process, it is kept for a period of time to reduce the return of the plate after the mold is opened. Elastic deformation. It can be seen from the above structure and working process that if a flat plate 6 is to be transformed into a corrugated plate, if the distance in the horizontal direction remains unchanged, the plate will actually be stretched. When the mold and the lower mold are formed, the sheet will be stretched and stretched, thereby making the sheet thinner. From the perspective of the working process of the utility model, each section of corrugation is formed sequentially in a separate order, so that the deformation of the deformed part during forming Because one side of the sheet is a free end, it will not be restricted, so the sheet will only produce very little stretching and extension during forming. After the entire sheet is formed into a corrugated sheet, the thickness of the sheet can be kept to the maximum extent, and the best sheet performance can be maintained. Moreover, the structural method is not easy to cause fractures for plates with poor plasticity, and the yield of finished products is improved.
