Description

Technical Field

[0001] The utility model relates to the technical field of compression molding of composite material (glass fiber) products with relatively complex shapes, in particular to a flat battery frame preforming device. Background Art

[0002] The commonly used composite material product forming process includes the following two aspects: 1. Forming, that is, laying the prepreg into a certain shape according to the requirements of the product, which is generally the shape of the product. 2. Curing, that is, the prepreg that has been laid into a certain shape is fixed under the influence of factors such as temperature, pressure, and time, and the expected performance requirements can be achieved. The above-mentioned forming refers to the final product forming. For products with more complex shapes such as flat battery frames, if the RTM process is used for production, when the fiber cloth is laid on the punch, it cannot be attached to the mold surface to form the shape of the product. It is necessary to use a special tooling to do a preforming before this. First, the fiber cloth is cut into the required shape with a cloth cutting machine and laid on the lower mold. The cylinder drives each die to press tightly, the mold is heated to 130°, and the pressure is maintained for 3 minutes to finalize. The preformed fiber cloth is placed on a simple appliance made of steel bars. However, the above preforming seriously affects the overall processing time, and a special flat battery frame preforming device is urgently needed. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a flat battery frame preforming device, which is used to pre-press the composite fiber cloth into the shape of a product before impregnation, so as to facilitate fitting with the mold surface on the RTM production line and ensure good material overlap and stable shape during the mold closing and glue injection process, so as to overcome the shortcomings of the above-mentioned prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A flat battery frame preforming device comprises: a mold frame, an upper die pressing mechanism installed on the top crossbeam of the mold frame, a left oblique die pressing mechanism and a right oblique die pressing mechanism installed on the side pressing bracket of the mold frame and located on both sides of the upper die pressing mechanism, and a left horizontal die pressing mechanism and a right horizontal die pressing mechanism installed on the working table of the mold frame;

[0006] The mold frame includes: a support frame, a work surface mounted on the support frame for mounting the lower mold, a top crossbeam mounted on the support frame and located above the work surface, and side pressure brackets mounted on the support frame and located on both sides of the top crossbeam;

[0007] The base of the lower mold is fixedly connected to the work surface by bolts, and the shape of the lower mold is consistent with the inner cavity of the product;

[0008] Wherein, the upper die pressing mechanism is used to press the top of the lower die, and the upper die pressing mechanism comprises: a first cylinder mounting plate mounted on the top crossbeam, a group of first cylinders mounted side by side on the first cylinder mounting plate, a first connecting plate connected to the piston rod of the first cylinder, an upper die mounted on the first connecting plate for pressing with the lower die, and a first guide sleeve mounted on the first cylinder mounting plate, a first guide rod is arranged between the first cylinder mounting plate and the first connecting plate, one end of the first guide rod is fixedly connected to the first connecting plate, and the other end is slidably connected in the first guide sleeve, and the first cylinder drives the upper die to press the upper end surface of the lower die;

[0009] Wherein, the left oblique pressing die mechanism and the right oblique pressing die mechanism are used for pressing the two side edges and the top edge of the lower mold, and the symmetrically arranged left oblique pressing die mechanism and the right oblique pressing die mechanism are respectively mounted on the two side pressing brackets of the support frame, and the left oblique pressing die mechanism and the right oblique pressing die mechanism respectively comprise: a cylinder mounting frame mounted on the side pressing bracket, a second cylinder mounted on the cylinder mounting frame, a second connecting plate connected to the second cylinder piston rod, an oblique pressing die mounted on the second connecting plate for pressing with the lower mold, and a second guide sleeve mounted on the cylinder mounting frame, a second guide rod is arranged between the cylinder mounting frame and the second connecting plate, one end of the second guide rod is fixedly connected to the second connecting plate, and the other end is slidably connected in the second guide sleeve, and the second cylinder drives the oblique pressing die to press the two side edges and the top edge of the lower mold;

[0010] Among them, the left horizontal pressing die mechanism and the right horizontal pressing die mechanism are used to press the two sides of the lower mold, and the symmetrically arranged left horizontal pressing die mechanism and the right horizontal pressing die mechanism are respectively installed on the work table and located on both sides of the lower mold. The left horizontal pressing die mechanism and the right horizontal pressing die mechanism respectively include: a second cylinder mounting plate and a linear slide rail installed on the work table, a third cylinder installed on the second cylinder mounting plate, a third connecting plate fixedly connected to the third cylinder piston rod and slidably connected to the linear slide rail, and a horizontal pressing die installed on the third connecting plate for pressing with the lower mold, and the third cylinder drives the horizontal pressing die to press the two sides of the lower mold.

[0011] As a preferred embodiment of the present invention, the upper pressing die and the horizontal pressing die are shaped as rectangular pressing plates, and the inclined pressing die is shaped as an L-shaped pressing plate.

[0012] As a preferred embodiment of the utility model, two groups of four linear slide rails are symmetrically installed on both sides of the lower mold, and the bottom of the third connecting plate is slidably connected to a group of linear slide rails through a slider.

[0013] As a preferred embodiment of the present invention, the diameter of the first guide rod is 30 mm, and the diameter of the second guide rod is 40 mm.

[0014] The advantages and positive effects of the utility model are:

[0015] 1. The utility model can quickly complete the preforming of raw materials of composite material products with relatively complex shapes. After being finalized, it is easy to lay on the RTM production line mold, can fit well with the mold, and ensure that the surface of the finished product is smooth and wrinkle-free.

[0016] 2. Since the left oblique die mechanism and the right oblique die mechanism of the utility model press downward at an inclined angle, the weight of the die and the connecting plate will cause the guide rod to bend, so the diameter of the guide rod is increased to 40 mm, and the guide length of the guide sleeve needs to be lengthened. Therefore, the cylinder mounting plate is changed to a welded frame.

[0017] 3. The left horizontal die pressing mechanism and the right horizontal die pressing mechanism of the utility model are arranged horizontally, and the linear slide rails are used instead of the guide rods, which can effectively solve the problem that the guide rods will bend downward after the die is overhanging, and the linear slide rails are also easy to install.

[0018] 4. The utility model can effectively solve the wrinkle problem in the die pressing process by adding a left oblique die pressing mechanism and a right oblique die pressing mechanism to press the edges of both sides of the upper end surface of the lower die and the position of the side surface close to the upper end surface.
