The method for fixing the mounting mechanism and the special heating die 10 for the channel steel type insulating section comprises the following steps:

firstly, placing two pressing plates 20 on the upper side and the lower side of the special heating mold 10 for the channel steel type insulating section respectively, then respectively penetrating a first screw 40 into a first mounting hole, finally connecting a first nut 41 on the upper end and the lower end of the first screw 40 in a threaded manner, and tightly pressing the pressing plates 20 by the first nut 41, so that the two pressing plates 20 are clamped at the upper end and the lower end of the special heating mold 10 for the channel steel type insulating section finally.

Step two, as the second screw 31 is fixedly connected with the pressure plate 20, the screw connection or the welding fixation can be adopted; the fourth blocking pipe 36 is firstly sleeved outside the second screw rod 31, then the fifth mounting hole 801 in the fourth positioning plate 80 penetrates through the second screw rod 31, then the third blocking pipe 35 is sleeved outside the second screw rod 31, the fourth mounting hole 701 in the third positioning plate 70 penetrates through the second screw rod 31, then the second blocking pipe 34 is sleeved outside the second screw rod 31, the third mounting hole 601 in the second positioning plate 60 penetrates through the second screw rod 31, then the first blocking pipe 33 is sleeved outside the second screw rod 31, the second mounting hole 501 in the first positioning plate 50 penetrates through the second screw rod 31, and finally the second nut 32 is in threaded connection with the second screw rod 31 so that the second nut 32 abuts against the first positioning plate 50.

The cross-sectional area of the second installation hole 501 is smaller than the cross-sectional area of the periphery of the first baffle pipe 33, the cross-sectional area of the third installation hole 601 is smaller than the cross-sectional area of the periphery of the second baffle pipe 34, the cross-sectional area of the fourth installation hole 701 is smaller than the cross-sectional area of the periphery of the third baffle pipe 35, the cross-sectional area of the fifth installation hole 801 is smaller than the cross-sectional area of the periphery of the third baffle pipe 35, and the cross-sectional area of the fifth installation hole 801 is smaller than the cross-sectional area of the periphery of the fourth. This enables the first pipe stopper 33 to limit the distance between the first positioning plate 50 and the second positioning plate 60, the second pipe stopper 34 to limit the distance between the second positioning plate 60 and the third positioning plate 70, the third pipe stopper 35 to limit the distance between the third positioning plate 70 and the fourth positioning plate 80, and the fourth pipe stopper 36 to limit the distance between the fourth positioning plate 80 and the pressing plate 20, which in turn controls the distance between the fourth positioning plate 80 and the inlet end of the special heating mold for channel steel type insulating section 10; finally, the following steps can be achieved: as shown in fig. 2, the distance between the first positioning plate 50 and the second positioning plate 60 is m, the distance between the second positioning plate 60 and the third positioning plate 70 is n, the distance between the third positioning plate 70 and the fourth positioning plate 80 is c, the distance between the fourth positioning plate 80 and the inlet end of the special heating die for a channel steel type insulating section 10 is d, and n > m > c ═ d needs to be satisfied. The reason why n, m, c, d are set according to the above relationship is as follows: because the dispersion degree of first locating plate 50 is the biggest, the dispersion degree of second locating plate 60 is the second, the concentration degree of third locating plate 70 is the highest, through the interval between extension first locating plate 50 and second locating plate 60, and prolong the interval between second locating plate 60 and third locating plate 70 to the biggest, glass fiber yarn and glass felt are passing through first locating plate 50, second locating plate 60, third locating plate 70, the in-process of fourth locating plate 80 in proper order, the resistance change when helping glass fiber yarn and glass felt to be tightened up and be the gradient change, avoid producing great fall, make glass fiber yarn and glass felt atress more even when receiving the bundle, it is more smooth-going in-process, this effectively reduces its probability of taking place wearing and tearing in the bundle receiving process. The utility model discloses in, glass fiber yarn and glass felt in the preforming in-process, through the quartic process of restrainting gradually, for once or twice fashioned restraint, the process of restrainting gradually through the quartic can show probability and the degree of wear that reduces glass felt and glass fiber yarn emergence wearing and tearing, helps improving off-the-shelf qualification rate.

When the channel steel type insulating section is produced by the company, the glass felts are arranged into three layers and are arranged in an upper, middle and lower mode, and a plurality of glass fiber yarns are filled between every two adjacent layers of glass felts, so that the compressive strength and the tensile strength of the finished section can be obviously improved. Therefore, when the impregnated glass mats pass through the first positioning plate 50, the uppermost glass mat passes through the first through-mat holes 51 and the length of the first through-mat holes 51 matches the width of the glass mat, the middle glass mat passes through the second through-mat holes 52 and the length of the second through-mat holes 52 matches the width of the glass mat, the lowermost glass mat passes through the third through-mat holes 53 and the length of the third through-mat holes 53 matches the width of the glass mat, and the first through-mat holes 51, the second through-mat holes 52 and the third through-mat holes 53 exactly match the glass mats; the distance between the first felt penetrating holes 51 and the second felt penetrating holes 52 is equal to the distance between the second felt penetrating holes 52 and the third felt penetrating holes 53, the length of the first felt penetrating holes 51 is greater than that of the third felt penetrating holes 53, and the length of the third felt penetrating holes 53 is greater than that of the second felt penetrating holes 52. The equal spacing arrangement is beneficial to the uniform distribution of the glass felt, and the lengths of the first felt penetrating hole 51, the second felt penetrating hole 52 and the third felt penetrating hole 53 are determined by the production process.

Further, the first threading holes 551 in the first threading hole group 55 are arranged at equal intervals, and the first threading holes 551 in two adjacent rows of the first threading hole groups 55 are arranged in a staggered manner, for example, the first threading holes 551 in the first row of the first threading hole group 55 and the first threading holes 551 in the second row of the first threading hole group 55 are arranged in a staggered manner. The glass fiber yarns after gum dipping are mutually supplemented, and are dispersed more uniformly in the section. According to the process requirements of my company, the number of first threading holes 551 in the first threading hole group 55 in the first row is 14, the number of first threading holes 551 in the first threading hole group 55 in the second row is 13, the number of first threading holes 551 in the first threading hole group 55 in the third row is 14, and the number of first threading holes 551 in the first threading hole group 55 in the fourth row is 13.

That is, the first felt penetration hole 51, the second felt penetration hole 52, the third felt penetration hole 53 and the first yarn penetration hole 551 mainly function as a limit.

Glass mat and glass fiber yarn can continue to pass second locating plate 60 after passing first locating plate 50, and second locating plate 60 plays limiting displacement on the one hand, and simultaneously, second locating plate 60 can also carry out first step to glass mat and glass fiber yarn and receive, and the concrete principle is as follows:

the restriction of the length of the glass mat as it passes through the fourth puncture hole 61 is enforced. When the glass yarn passes through the second punch group 62 arranged in the "means" form as a whole, the entire glass yarn layer is also forcibly restricted to the "means" form. As shown in fig. 7 and 8, the fourth felt penetration hole 61 includes a horizontal hole section 611, long strip hole sections 612 are respectively disposed on two sides of the horizontal hole section 611, the long strip hole sections 612 are communicated with the horizontal hole section 611, and an included angle between the two long strip hole sections 612 is 100 °. The second thread hole group 62 comprises a horizontal unit 621 which is horizontally arranged, two sides of the horizontal unit 621 are respectively provided with an inclined unit 622 which is obliquely arranged, and an included angle between the two inclined units 622 is 109 degrees; the horizontal unit 621 includes a plurality of second threading holes 6211 arranged in a horizontal line shape, and the inclined unit 622 includes a plurality of third threading holes 6221 arranged in an inclined line shape. The included angle between the two strip hole sections 612 is 100 degrees, and the included angle between the two inclined units 622 is 109 degrees; there is an angle difference, which makes the glass fiber yarn layer between the adjacent two fourth through holes 61 easier to be wrapped and bent by the glass mat. That is, the glass mat and the glass fiber yarns are forced to be shaped with the cross section in the shape of the "restriction" during the process of passing through the second positioning plate 60, so as to facilitate the subsequent shaping again into the groove-shaped structure.

After the glass mat and the glass fiber yarns pass through the second positioning plate 60, the glass mat and the glass fiber yarns can continue to pass through the third positioning plate 70, on one hand, the third positioning plate 70 plays a limiting role, and meanwhile, the third positioning plate 70 can further bundle the glass mat and the glass fiber yarns so that the glass mat and the glass fiber yarns are forcibly shaped into a groove-shaped structure. The groove-shaped structure is the section shape of the channel steel. As is well known, channel steel is a long steel bar with a groove-shaped cross section; therefore, the first through-hole 71 and the second through-hole 81 can be said to be configured to conform to the shape of the channel.

The glass mat and the glass fiber yarns can continuously pass through the fourth positioning plate 80 after passing through the third positioning plate 70, the fourth positioning plate 80 plays a limiting role on the one hand, and meanwhile, the fourth positioning plate 80 can also carry out final bundling on the glass mat and the glass fiber yarns so that the glass mat and the glass fiber yarns are thoroughly shaped into a groove-shaped structure. The first and second through

holes

71 and 81 are through holes through which the glass mat and the glass fiber yarn are commonly passed. Wherein the first through holes 71 have a hole width x, the second through holes 81 have a hole width y, and x > y. This makes the hole width of the first perforation 71 wider, that is, the glass mat and the glass fiber yarn are pre-shaped into the groove-shaped structure at the first perforation 71 and finally completely shaped into the groove-shaped structure at the second perforation 81, and the glass mat and the glass fiber yarn at the second perforation 81 will be squeezed more densely, which is beneficial for the glass mat and the glass fiber yarn to enter the interior of the special heating mold 10 for channel steel type insulation section in the following process.

In the above embodiment, the glass mat and the glass fiber yarn are limited and positioned after passing through the first positioning plate 50; the first extrusion of the glass mat into the 'comfort' shape and the first extrusion of the glass fiber yarn layer into the 'comfort' shape by the second positioning plate 60; the glass fiber mat and the glass fiber yarns are extruded into a preformed structure with uniform and compact structure distribution before entering the special heating mould 10 for the channel steel type insulating section, so that the glass fiber mat and the glass fiber yarns can conveniently enter the special heating mould 10 for the channel steel type insulating section, the abrasion between the glass fiber mat and the glass fiber yarns and the special heating mould 10 for the channel steel type insulating section is small, the abrasion between the glass fiber mat and the glass fiber yarns is small, the distribution is uniform, the structure is complete, the prepared channel steel type insulating section has uniform texture, and the mechanical property of the channel steel type insulating section is improved; in addition, first locating plate 50, second locating plate 60, third locating plate 70 and fourth locating plate 80 all have the effect of location to can prevent effectively that glass felt and glass fiber yarn from taking place the dislocation, just also effectively reduce the finished product and weave the defect that shows, the surface is coarse, the size is unstable, is showing the qualification rate that improves the finished product. The probability of defects of weaving appearance, rough surface, unstable size and the like of a finished product is not more than 0.9 percent, the qualification rate of the finished product is obviously improved, and the finished product has smooth surface, stable size, high mechanical strength and good quality.

The pre-forming device for the channel steel type insulating section is simple in structure and convenient to install, disassemble and replace; the glass mat and the glass fiber yarns are preformed by four groups of positioning plates (a first positioning plate 50, a second positioning plate 60, a third positioning plate 70 and a fourth positioning plate 80) for performing, and the glass mat and the glass fiber yarns are separated, so that the glass mat and the glass fiber yarns can be distributed and distributed clearly, and the processing is convenient; meanwhile, the damage of the glass felt and the glass fiber yarns caused by one-step forming can be effectively prevented.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
