Description

A mould for 45 bordures

Technical Field

The utility model relates to the field of dies, in particular to a die for producing 45-degree edge wrapping of a refrigerator door shell.

Background

When the refrigerator door shell is produced, in order to enable the edge to be matched with a concave-convex die, a groove with a sinking structure is pushed out, namely 45-degree wrapping is carried out, the forming wrapping is provided with two bending surfaces relative to a plate to be processed, the first bending surface is a vertical surface, the other bending surface is a parallel surface which is concave downwards, in order to save production arrangement, the structure is supported by a wrapping concave die, and a corresponding shape is pushed out by a wrapping convex die.

The traditional package Bian Aomo is flat cuboid supporting shoe, and package Bian Tumo is L type structure, and the product is fixed on the die of borduring, and reuse press promotes package Bian Tumo, extrudees required bordure, but traditional terrace die end only adopts the button head design, can wait to process the board edge and can appear fold, tear, the condition such as oblique line because of the atress is inhomogeneous at the initial stage in the extrusion process, causes product defect, and similar defective rate is relatively higher moreover.

If the product is an internal part, the small defects can not cause product quality problems, but similar defects can not be shielded after paint spraying aiming at external devices such as refrigerator door shells, and the product appearance is affected, so that the existing edge-covering die needs to be improved, and the product defect rate is reduced.

Disclosure of Invention

The utility model aims to solve the technical problem of realizing a 45-degree edge-wrapping die capable of improving the production qualification rate.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a mould for 45 bordures, mould includes die and the terrace die of borduring, the terrace die of borduring comprises fixed part and shaping portion L shape structure, the tip of shaping portion bottom surface is equipped with down the inclined plane, the tip of shaping portion both sides is equipped with the side inclined plane.

And a round angle is arranged between the side inclined surface and the end surface of the forming part.

The radius of the round angle is 220-280mm

The width of the end face of the forming part is 20+/-1 mm.

The widths of the side inclined planes and the lower inclined plane are 35+/-1 mm.

The package Bian Aomo is a flat cuboid metal block, and the edge-wrapping female die is used for fixing a plate to be processed.

And the fixing part and the forming part of the edge-covering male die are respectively provided with a mounting hole for fixing the edge-covering male die on the press.

The utility model has the advantages that the die only changes the male die structure, increases the multi-side bevel structure, reduces the equipment upgrading cost, ensures that the stress of the plate to be processed is more uniform when the plate is initially pushed in, greatly reduces the processing defective rate, and can be suitable for 45-degree edge-covering processing of the refrigerator door shell.

the labels in the above figures are: 1. a plate to be processed; 2. a binding area; 3. a bag Bian Aomo; 4. a bag Bian Tumo; 5. a side slope; 6. and a lower inclined plane.

Detailed Description

The following detailed description of the embodiments of the utility model, such as the shape and construction of the components, the mutual positions and connection relationships between the components, the roles and working principles of the components, the manufacturing process and the operating and using method, etc., is provided to assist those skilled in the art in a more complete, accurate and thorough understanding of the inventive concept and technical solution of the present utility model.

The die comprises an edge-covering female die 3 and an edge-covering male die 4, the edge-covering female die 3 is of an original structure, the whole body is a flat cuboid metal block, a mounting hole matched with a press is formed in the die, the edge-covering female die 3 is used for fixing a plate 1 to be processed, when the refrigerator door shell is used, the edge of the plate 1 to be processed (the refrigerator door shell) which needs to be subjected to edge-covering treatment is fixed on the edge-covering female die 3 at one time, the part of the edge of which is provided with the edge-covering structure extends out of the edge-covering female die 3, the part is extruded by the edge-covering male die 4 and bends, and the working relative position between the edge-covering male die 4 and the edge-covering female die 3 is shown in fig. 4.

The die is an improvement on the existing die, mainly comprises an edge-covering male die 4, the structure of the edge-covering male die 4 is shown in fig. 1-3, the edge-covering male die 4 is in an L shape, one section is a fixing part, the other section is a forming part, the fixing part is mainly used for being fixed, the forming part is used for being in extrusion contact with a plate 1 to be processed, in order to ensure that the pressure in two directions at the initial stage of contact is slowly improved, the conditions of tearing, wrinkling, inclined lines and the like caused by excessive extrusion are avoided, a lower inclined plane 6 is arranged at the end part of the bottom surface of the forming part, side inclined planes 5 are arranged at the end parts of the two sides of the forming part, the bottom surface of the forming part is one surface which is in contact with the plate 1 to be processed, and the bottom surface and the side surface of the forming part are all the positions which are in contact with the plate 1 to be processed at first, so that the defective rate can be greatly reduced through inclined plane buffering.

Both sides all set up the production demand of borduring that side inclined plane 5 can use the different sides of product, have the fillet between side inclined plane 5 and the shaping portion terminal surface for further promotion cushioning effect, and the radius of fillet is 220-280mm, adopts R250mm preferably to the size of shaping portion preferably adopts the width of terminal surface to be 20+ -1 mm, and the width of side inclined plane 5 and lower inclined plane 6 is 35+ -1 mm.

The fixing part and the forming part of the edge-covering male die 4 are respectively provided with a mounting hole for fixing to a press, and the mounting holes of the fixing part and the forming part are respectively provided with two mounting holes for adapting to the installation requirements of the press matched at present. Because the improvement only adjusts the structure of the edge-covering male die 4, other parts are changed, and the size of the edge-covering male die 4 is unchanged, the stress of the plate 1 to be processed is more uniform when the product equipment is initially pushed in without adjustment, the processing defective rate is greatly reduced, the refrigerator door shell 45-degree edge-covering processing can be adapted, the improvement cost of the improved equipment is extremely low, and the popularization and promotion are also utilized.

While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is capable of being modified or applied directly to other applications without modification, as long as various insubstantial modifications of the method concept and technical solution of the utility model are adopted, all within the scope of the utility model.
