Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fiber composite material forming, and particularly relates to a basalt fiber composite material grid forming device. BACKGROUND

[0002] Basalt fiber is a continuous fiber drawn from natural basalt. Basalt fiber is a continuous fiber drawn at high speed through a platinum-rhodium alloy wire drawing bushing, and the color is generally brown. Basalt fiber is a new type of inorganic, environmentally friendly and high-performance fiber material, which is made by high-temperature melting of basalt ore and wire drawing.

[0003] When the basalt fiber composite material grid is made, the fiber strips made of basalt fiber are generally arranged into a grid shape and placed in a mold, and then the fiber strips in the mold are hot-pressed by a hot-pressing mechanism to form the basalt fiber composite material grid.

[0004] In this process, due to the difference in thickness of the fiber strips, the hot-pressing force on the grid nodes of the fiber strips is deviated during hot-pressing. The fiber strips at the grid nodes with larger hot-pressing force are prone to hot fracture, and the fiber strips at the grid nodes with smaller hot-pressing force have poor connection stability, thereby resulting in poor tensile performance of the basalt fiber composite material grid after forming, which is prone to breakage during subsequent use, affecting the forming quality and subsequent service life of the basalt fiber composite material grid.

It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0045] The specific implementation of the present application is described in detail below in combination with specific examples.

[0046] As Figures 1-9As shown, the basalt fiber composite grid forming device provided by the application comprises a support frame 1, the support frame 1 is fixedly connected with a base 2, a plurality of node adjusting mechanisms 6 are arranged at equal intervals in the base 2, the node adjusting mechanism 6 can limit the fiber strips at the grid node position, and the node adjusting mechanism 6 can push the fiber strips near the grid node position to move;

[0048] The support frame 1 is fixedly connected with an upper top plate 12, the upper top plate 12 is fixedly connected with a hot-pressing forming mechanism 7, the hot-pressing forming mechanism 7 can hot-press all the grid nodes at the same time, and the upper top plate 12 is further connected with a flattening mechanism 8, the flattening mechanism 8 can flatten the thickness of the grid nodes;

[0049] The base 2 is provided with an electric heater 10 and a water pump 11, one end of the water pump 11 is communicated to the outside of the base 2, under the pump pressure of the water pump 11, the node adjusting mechanism 6 can spray and cool the fiber strips near the grid node position.

[0050] In this embodiment, a plurality of fiber strips are cross-placed on the upper side of the base 2, one end of each fiber strip is elastically limited by the positioning mechanism 3, and the other end of the fiber strip is tensioned and positioned by the tension mechanism 4, at this time, the grid nodes formed by the cross of all the fiber strips are correspondingly distributed on the upper side of each node adjusting mechanism 6;

[0051] The flattening mechanism 8 is started, the flattening mechanism 8 can hot-press and flatten the thickness of the grid nodes on each node adjusting mechanism 6, the material body at the grid node with a relatively thick thickness is flattened, and the effect of heat makes the material body better plasticity after being pressed, the node adjusting mechanism 6 can limit the fiber strips at the grid node position, so as to avoid the grid nodes formed by the cross of the fiber strips from deviating from the position under the action of the pressure and affecting the hot-pressing forming effect of the fiber strips at the grid nodes; before this, the water pump 11 is used to pass clean water into the base 2, and the electric heater 10 is started to heat the clean water, the hot water preheats the fiber strips at the grid nodes through the node adjusting mechanism 6, and further improves the plasticity effect of the fiber strips;

[0052] When the fiber strips at each grid node are flattened by the flattening mechanism 8, the fiber strips are prone to deformation and adhesion, and the fiber strips are prone to generate more burrs after being reciprocally extruded by the flattening mechanism 8. At this time, the node adjusting mechanism 6 is started to push the fiber strips near the grid node position to move, so that the fiber strips are fully separated from each other, facilitating the subsequent start of the tensioning mechanism 4 to tension and limit all the fiber strips again, thereby improving the uniformity of the distribution of the fiber strips and the thickness uniformity of each grid node; then the hot-press forming mechanism 7 is started to hot-press and bond the flattened and repositioned grid nodes, so that the fiber strips form a net body.

[0053] When the net body is hot-pressed and formed, the hot-press forming mechanism 7 is started to end the hot-pressing of the fiber strips at each grid node of the net body, and the node adjusting mechanism 6 is started to spray and cool the fiber strips near the grid node position, and the node adjusting mechanism 6 can push the fiber strips near the grid node position to move, avoiding the adhesion of the fiber strips at each grid node to the surface of the node adjusting mechanism 6.

[0054] As shown in Figure 7 and Figure 8 , the node adjusting mechanism 6 of the basalt fiber composite grid forming equipment provided by the application comprises a sliding rod 61, a support disc 62, a limiting column 63 and a spray hole 64;

[0055] A plurality of sleeves 9 are rotationally connected to the upper end surface of the base 2 at equal intervals, and a sliding rod 61 is vertically and slidingly connected in each sleeve 9. The upper end of the sliding rod 61 is fixedly connected with a support disc 62. Four limiting columns 63 are arranged in a rectangular shape on the support disc 62. All the limiting columns 63 are vertically and slidingly and elastically connected with the support disc 62. A plurality of spray holes 64 are formed in the limiting column 63 near the root. A driving assembly 65 is connected with all the sliding rods 61. The driving assembly 65 is used to drive all the sliding rods 61 to reciprocally rotate at the same time.

[0056] The limiting column 63 is in communication with the inner cavity of the base 2 through the support disc 62 and the sliding rod 61. A one-way hydraulic valve is arranged in the sliding rod 61.

[0057] In this embodiment, the support disc 62 can support each grid node, and each limiting column 63 on the support disc 62 can limit the fiber strips around the grid node. When the hot-press forming mechanism 7 is pressed down, all the sliding rods 61 can push the corresponding support disc 62 to maintain the same extrusion force as the hot-press forming mechanism 7 under the action of the water pressure in the base 2, so that all the grid nodes can be uniformly stressed.

[0058] The starting driving assembly 65 drives all the sliding rods 61 to reciprocating rotate, all the sliding rods 61 drive the support disc 62 connected therewith to reciprocating rotate, and each limiting column 63 on the support disc 62 reciprocating pulls the fiber strips around the grid node, so that the fiber strips can be dispersed among each other.

[0059] When the net body is hot-pressed, the hot-pressing mechanism 7 is started to lift the height to end the hot-pressing of the fiber strips at each grid node of the net body, and after the downward pressure of the hot-pressing mechanism 7 is lost, each limiting column 63 extends outside the support disc 62, the water pump 11 is started to increase the water pressure in the base 2, the one-way hydraulic valve in all the sliding rods 61 is conducted, the support disc 62 drives all the limiting columns 63 to spray and cool the grid node, so that each grid node can be quickly cooled and solidified, and in the process, the support disc 62 reciprocating rotates, the support disc 62 drives all the limiting columns 63 to reciprocating pull the fiber strips near the grid node, effectively avoiding the fiber strips at the grid node from sticking and solidifying on the surface of the support disc 62.

At this time, the guide shaft 83 guides the electric telescopic frame 81. By starting the electric telescopic frame 81 to extend, the electric heating roller 84 descends in the height direction. The electric heating roller 84 can roll each grid node while moving horizontally.

[0067] When the electric heating roller 84 moves horizontally to roll each grid node, if the value of the pressure sensor exceeds the pressure threshold in the data processor, the motor 85 drives the threaded shaft 82 to rotate back and forth, so that the electric heating roller 84 on the electric telescopic frame 81 rolls back and forth near this part of the grid node, thereby improving the flatness of the grid node.

[0068] During this process, each limiting post 63 on the support plate 62 can elastically contact the electric heating roller 84, thereby limiting each grid node and preventing the fiber strip from detaching from the surface of the support plate 62 under the action of roller pressure.

[0089] During this process, each limiting column 63 on the support disc 62 can be in elastic contact with the electric heating roller 84, thereby limiting each grid node, avoiding the fiber strips from separating from the surface of the support disc 62 under the action of the roller pressure, and avoiding the grid nodes formed by the crossing of the fiber strips from deviating from the position under the action of the pressure, thereby affecting the hot-pressing forming effect of the fiber strips at the grid nodes; before this, the water pump 11 is used to pass clean water into the base 2, and the electric heater 10 is started to heat the clean water, the hot water heats the sliding rod 61, the sliding rod 61 conducts heat to the support disc 62 to preheat the fiber strips at the grid nodes, thereby further improving the plasticity of the fiber strips;

[0090] When the fiber strips at each grid node are flattened by the flattening mechanism 8, the fiber strips are easily deformed and adhered to each other, and a large number of burrs are easily generated after the fiber strips are reciprocatingly extruded by the flattening mechanism 8, and when the fiber strips are subsequently pulled tight, the fiber strips are easily rubbed and pulled by each other;

[0091] At this time, the driving assembly 65 is started to drive all the sliding rods 61 to reciprocatingly rotate, all the sliding rods 61 drive the support discs 62 connected thereto to reciprocatingly rotate, and each limiting column 63 on the support disc 62 reciprocatingly pulls the fiber strips around the grid node, and the burrs on the surface of the fiber strips can be removed through each limiting column 63, thereby fully separating the fiber strips from each other, facilitating the subsequent starting of the tensioning mechanism 4 to pull and limit all the fiber strips again, thereby improving the uniformity of the distribution of the fiber strips and the thickness of each grid node;

[0092] Subsequently, the hot-pressing forming mechanism 7 is started to heat-press and bond each grid node after being flattened and repositioned, so that the grid body is formed between the fiber strips;

[0093] When the grid body is hot-pressed and formed, the hot-pressing forming mechanism 7 is started to lift to an end height to heat-press the fiber strips at each grid node of the grid body, and after the downward pressure of the hot-pressing forming mechanism 7 is lost, each limiting column 63 extends to the outside of the support disc 62, the water pump 11 is started to increase the water pressure in the base 2, all the one-way hydraulic valves in the sliding rods 61 are conducted, the support disc 62 drives all the limiting columns 63 to spray and cool the grid nodes, so that each grid node can be quickly cooled and solidified, and during this process, the support disc 62 reciprocatingly rotates, the support disc 62 drives all the limiting columns 63 to reciprocatingly pull the fiber strips near the grid nodes, thereby effectively avoiding the fiber strips at the grid nodes from adhering and solidifying to the surface of the support disc 62.
