Description

Technical Field

[0001] The invention belongs to the technical field of glass fiber reinforced plastic processing, and in particular relates to a flow guide pipe processing device. Background Art

[0002] Glass fiber reinforced plastic (FRP), also known as GFRP, is fiber reinforced plastic. It generally refers to unsaturated polyester, epoxy resin and phenolic resin matrix reinforced with glass fiber. It is a reinforced plastic with glass fiber or its products as reinforcing materials. It is called glass fiber reinforced plastic, or FRP. It is light and hard, non-conductive, stable in performance, high in mechanical strength, less recycled, and corrosion-resistant. It can replace steel to manufacture machine parts and automobile and ship hulls.

[0003] Most of the existing FRP products are produced using the RTM process. The specific steps are: first, a reinforcement material preform designed according to performance and structural requirements is laid in the mold cavity, and then a special resin system is injected into the closed mold cavity using an injection device. The exhaust holes set around the mold ensure that the resin flows smoothly and discharges all the gas in the mold cavity and thoroughly infiltrates the fibers, and then the pressure is maintained and heated. To prevent the resin from overflowing, a guide tube (about φ10) is mostly inserted at the exhaust hole for diversion. After the RTM process is completed, the waterproof silicon mud used to seal the outer wall of the guide tube solidifies, and the resin adhered to the inner wall solidifies. In addition, the guide tube is mostly made of plastic, which constitutes solid waste and is very inconvenient to handle. Summary of the invention

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0028] The up-down, left-right, front-back directions described in the present invention refer to Figure 1 The up and down, left and right, inside and outside directions.

[0029] like Figures 1 to 5 As shown, the guide pipe processing equipment provided by the present invention includes: a vertical plate 10, a guide head 20, and a transfer wheel 30, wherein the vertical plate 10 extends vertically in the front-to-back direction, there are two vertical plates 10 and they are spaced apart in the left-to-right direction, a first through hole 11 is opened on the vertical plate 10, and the first through hole 11 is a rectangular hole, the guide head 20 is cylindrical and connected to the front surface of the vertical plate 10, a second through hole 21 is arranged at the center of the guide head 20, and the second through hole 21 is a circular hole, and the transfer wheel 30 is rotatably mounted between the two vertical plates 10, and the transfer wheel 30 includes an upper wheel 30a and a lower wheel 30b correspondingly arranged in the up-down direction, and the corresponding arrangement means that the projections of the upper wheel 30a and the lower wheel 30b in the up-down direction coincide with each other; the inner diameter of the second through hole 21 matches the outer diameter of the guide pipe. Matching means that when the guide tube passes through the second through hole 21, the gap between the inner wall of the second through hole 21 and the outer wall of the guide tube is a matching gap, and the front part of the second through hole 21 is connected with a conical surface 22 extending obliquely backward and outward. The transfer wheel 30 is provided with an annular groove 31, and the annular groove 31 is used to form a cavity 32 aligned with the second through hole 21 between the upper wheel 30a and the lower wheel 30b, and the cavity 32 is used for the guide tube to pass through. The height of the cavity 32 in the up and down direction is smaller than the outer diameter of the guide tube, so that when the guide tube passes through, the upper and lower ends of the guide tube are squeezed tightly, and a blade 12 with a cutting edge 13 facing forward is inserted into the first through hole 11, and the end of the blade 12 passes through the first through hole 11 and extends into the rear of the cavity 32, so as to cut open the guide tube passing through the cavity 32.

[0030] The advantage of such a configuration is that when the guide tube is inserted into the second through hole, the conical surface can be used to separate the waterproof silicon mud on the outer wall of the guide tube, and the guide tube can be introduced into the cavity so that it can be squeezed by the transfer wheel, and then driven to move forward by the rotation of the transfer wheel. During the movement, the guide tube can also be cut open by a blade, thereby facilitating the recycling of the guide tube and the resin. The equipment has high processing efficiency, low use cost, and is suitable for popularization and use.

[0031] The bottom wall of the annular groove 31 is gradually concave from both ends to the middle, forming an arc-shaped clamping surface. The arc-shaped clamping surface can deform the cross-section of the guide tube into an elliptical ring, increase the contact area between the bottom wall of the annular groove 31 and the outer wall of the guide tube, and use the rebound force generated by the deformation of the guide tube to increase the friction between the bottom wall of the annular groove 31 and the outer wall of the guide tube to avoid slipping.

[0032] In order to achieve synchronous rotation of the upper wheel 30a and the lower wheel 30b and avoid slipping between the upper wheel 30a and the lower wheel 30b, and to achieve the purpose of driving the guide tube to move backward in the horizontal direction, in this embodiment, an annular tooth surface 33 is provided on the upper wheel 30a and the lower wheel 30b, and the annular tooth surface 33 is composed of a number of racks extending in the horizontal direction, and these racks are evenly distributed along the circumferential direction of the upper wheel 30a or the lower wheel 30b. The annular tooth surface 33 is located on both sides of the annular groove 31, and the lower part of the annular tooth surface 33 on the upper wheel 30a is meshed with the upper part of the annular tooth surface 33 on the lower wheel 30b, so that the upper wheel 30a and the lower wheel 30b can maintain synchronous rotation with the same rotation speed and opposite rotation direction.

[0033] In this embodiment, a horizontal knife groove 14 for placing a blade 12 is connected to the vertical plate 10, and the horizontal knife groove 14 extends in the horizontal direction. A notch 15 for placing the blade 12 is opened on the horizontal knife groove 14, and the end of the horizontal knife groove 14 is aligned with the first through hole 11. The blade 12 and the notch 15 of the horizontal knife groove 14 are of equal width. The blade 12 can be slidably placed in the notch 15 of the horizontal knife groove 14, and the horizontal plane where the cutting edge 13 of the blade 12 is located is at an equal distance from the axis of the upper wheel 30a and the lower wheel 30b. The advantage of this arrangement is that it can The side wall of the notch 15 is used to press the blade 12 against the blade for fixation, and the blade 12 can be easily repaired and replaced after it is worn. During debugging, the cutting effect of the guide tube can be adjusted by simply pushing or pulling out the blade 12. The operation is convenient. The angle between the horizontal knife groove 14 and the vertical plate 10 is 50-60°. Specifically, the angle is 56°, so that the extension direction of the blade 12 can also present an angle of 56° with the travel direction of the guide tube, which can reduce the resistance to the guide tube and make it travel smoothly, and can also reduce the wear degree of the blade 12 and extend its service life.

[0034] In this embodiment, there are two horizontal knife grooves 14, which are respectively connected to the two vertical plates 10 and symmetrically distributed along the axis of the second through hole 21. The advantage of this arrangement is that the two blades 12 can be used to split the guide tube from both sides at the same time. During splitting, the forces applied by the two blades 12 in the radial direction of the guide tube offset each other, and no additional bending of the guide tube is caused, making it more convenient to separate the resin from the guide tube later.

[0035] The height of the cavity 32 in the up and down directions is very important. If the height is too high, the degree of deformation of the guide tube will be too small, the contact area between the bottom wall of the annular groove 31 and the outer wall of the guide tube will be too small, and the friction will be insufficient. When the transfer wheel 30 rotates, relative sliding is likely to occur between the guide tube and the transfer wheel 30. If the height is too low, the degree of deformation of the guide tube will be too large, the inner walls on both sides of the guide tube will be squeezed against each other, and the clamping force on the blade 12 will be too large, which will accelerate the wear of the blade 12 and affect the movement of the guide tube. Preferably, the height is 70%-90% of the outer diameter of the guide tube. In the present embodiment, the height is 86% of the outer diameter of the guide tube.

[0036] To facilitate replacement of the guide head 20 , in this embodiment, the guide head 20 is inserted into a guide head seat 23 and fixed to the front surface of the vertical plate 10 through the guide head seat 23 . A locking bolt 24 for fixing the position of the guide head 20 is provided on the guide head seat 23 .

[0037] The cone angle of the conical surface 22 is very important. If the cone angle is too large, the scraped waterproof silicon mud will easily accumulate in the front of the second through hole 21, affecting the movement of the guide tube. If the cone angle is too small, the scraped waterproof silicon mud will easily adhere to the conical surface 22, especially the waterproof silicon mud at the upper part, which is not easy to fall off by itself. The cone angle is preferably 65-85°. In the present embodiment, the cone angle is 77°.

[0038] In this embodiment, in order to ensure that the spacing between the vertical plates 10 remains stable, a spacer column 16 is further provided between the two vertical plates 10. To facilitate driving and installation and fixation, the guide tube processing equipment also includes a motor 41, a base plate 42, and a frame 43. The motor 41 is connected to one of the vertical plates 10 and is used to drive the lower wheel 30b to rotate. The base plate 42 is used to support the vertical plate 10, and the base plate 42 is arranged on the top of the frame 43.

[0039] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
