Embodiment 1

[0029] refer to figure 1 , a fully automatic hydraulic glue injection machine, including a motor 1, an oil pump 2, a three-way overflow valve 4, an oil tank 3, a first electric four-way valve 5, a power pump 6, a working pump 7, a glue inlet valve 12, a first Travel switch 9 and second travel switch 10.

[0030] The bottom of oil tank 3 is provided with oil outlet, and the top of oil tank 3 is communicated with oil return pipe 17, and oil return pipe 17 rings a water-cooled box 16, and the top of water-cooled box 16 has water outlet, and the bottom has water inlet.

[0031] The oil pump 2 is driven by the motor 1, the oil inlet of the oil pump 2 communicates with the oil outlet of the fuel tank 3 through a pressure-resistant pipe, and the oil outlet of the oil pump 2 is connected with a three-way overflow valve 4.

[0032] The overflow port of the three-way relief valve 4 is connected to the fuel tank 3 through a pressure-resistant pipe, and the fuel tank 3 → oil pump 2 → thr...

Embodiment 2

[0054] refer to Image 6 , the difference between this embodiment and embodiment 1 is that the miniature piston pump 14 in the glue feeding control device is changed to compressed air drive:

[0055] The two ends of the micro-piston cylinder are provided with air ports respectively, and the two air ports are respectively communicated with the two connecting ports of the second electric four-way valve (15) through pressure-resistant pipes, and the other two ports of the second electric four-way valve (15) are The connection ports are respectively a compressed air interface and an exhaust port; the first travel switch (9) and the second travel switch (10) are electrically connected to the second electric four-way valve (15).

[0056] When in use, connect the compressed air interface of the second electric four-way valve (15) to the compressed air source with a pressure-resistant tube. The main difference between the working process of this embodiment and Embodiment 1 is the glue...

Embodiment 3

[0058] refer to Figure 7 , the difference between this embodiment and Embodiment 1 is that the glue feeding control device is changed to an electric valve 23, the electric valve 23 is connected to the glue feeding valve 12, the glue feeding valve 12 is driven by the electric valve 23, the first stroke switch 9 and the second stroke The switch 10 is also electrically connected to the electric valve 23 .

[0059] The difference between the working process of this embodiment and Embodiment 1 lies in the glue feeding control device: during the glue suction process, the electric valve 23 drives the glue inlet valve 12 to keep it in the open state. When the stroke switch 9 is touched), the electric valve 23 immediately drives the glue inlet valve 12 to close it, and then enters the glue injection process. During the glue injection process, the glue inlet valve 12 is always in the closed state. When the glue injection is completed (the connecting flange 8 moves to the second travel...

Abstract

The invention relates to a device for manufacturing a fiber enhanced compound part by using a pultrusion technique and provides a full-automatic hydraulic glue-injection machine, which comprises an oil tank, a motor, an oil pump, a three-way overflow valve, two first motor-driven four-way valves, a power pump, a working pump, a glue-feeding control device, a glue-feeding valve, and the like, wherein the loop of a driving oil channel is formed by connection of the oil tank, the oil pump, the three-way overflow valve, a first motor-driven four-way valve, the power pump, a first motor-driven four-way valve, and the oil tank in sequence; the end parts of piston rods of the power pump and the working pump are coaxially firmly connected through a flange; the working pump is connected to a glue-feeding pipe and a glue-injection pipe; the glue-feeding valve is arranged on the glue-feeding pipe and is driven by the glue-feeding control device; and first and second position switches are connected to the first motor-driven four-way valve and the glue-feeding control device and are triggered by the connected flange. The full-automatic hydraulic glue-injection machine has the substantial characteristics and obvious progresses that: 1) resins are supplied to a sealed bath slot, the pressure of the resins in the sealed bath slot is kept stable, and the manufacturing quality of the compound part is increased; and 2) the structure is simple, the degree of automation is high, the working is stable, and the machine is safe and reliable.

Description

technical field [0001] The invention relates to equipment for manufacturing fiber-reinforced composite parts by pultrusion molding technology, and is particularly suitable for a glue injection machine for manufacturing composite parts with epoxy resin or polyurethane resin as a matrix. Background technique [0002] The process of manufacturing composite parts with epoxy resin or polyurethane resin as the matrix is ​​as disclosed in Chinese patent 200680043251, which is to pass the drawn tow of fiber material (such as glass fiber, polymer fiber, or carbon fiber) through a liquid An atmospheric pressure bath (usually an open tank or cylinder) of resin material is used to coat it, and after coating, the fiber tow is drawn through a curing die to polymerize and cure the resin. One of the difficulties of coating the tow in a normal pressure bath is that the individual fibers or filaments in the tow cannot be fully coated with resin, which directly affects the quality of the manuf...
