Description

Technical Field

[0001] This utility model belongs to the field of sintered felt processing technology, and in particular relates to a pre-compression tooling for metal fiber sintered felt. Background Technology

[0002] Metal fiber sintered felt is a porous material formed by the disordered stacking and high-temperature sintering of metal fibers (such as stainless steel and nickel-based alloys). It features high porosity, large specific surface area, high temperature resistance, and corrosion resistance. Its three-dimensional network structure endows it with excellent filtration, separation, noise reduction, and catalytic carrier functions, making it widely used in chemical, energy, environmental protection, and biomedical fields. During the processing of metal fiber sintered felt, a pre-compression device is generally used to pre-compress it.

[0003] However, existing metal fiber sintered felts often exhibit numerous burrs on their surface during pre-compression. Because current technologies lack a heating softening device, the surface of the metal fiber sintered felt is difficult to smooth during pre-compression. Furthermore, the pre-compression devices used lack adaptive adjustment based on the thickness of the metal fiber sintered felt, making it impossible to pre-compress metal fiber sintered felts of varying thicknesses. Therefore, we provide a metal fiber sintered felt pre-compression fixture to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-compression fixture for metal fiber sintered felt. The heating pipe increases the temperature of the surface of the compression roller, thereby increasing the temperature of the surface of the metal fiber sintered felt and softening the soft structure on the surface of the metal fiber sintered felt, making the metal fiber sintered felt flat. At the same time, the compression roller can be adaptively adjusted according to the metal fiber sintered felt by moving up and down inside the U-shaped frame.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a pre-compression fixture for metal fiber sintered felt, including a base plate; a U-shaped frame is fixed on the upper end face of the base plate, and multiple sets of evenly distributed compression rollers are arranged between the U-shaped frame and the base plate. The compression rollers are composed of two sets of semi-cylindrical columns, and each compression roller has a circuit tube inside. The surface wall of each circuit tube is fixed with a heating tube, and an adjustment plate is arranged between the U-shaped frame and the compression rollers.

[0007] The present invention is further configured such that adjustment openings are provided on both sides of the U-shaped frame, and the two ends of the adjustment plate are slidably disposed in the corresponding adjustment openings.

[0008] The present invention is further provided that the end face of the adjusting plate passing through the adjusting port is provided with a locking strip that connects to the side wall of the U-shaped frame, and the locking strip is threadedly connected to the adjusting plate by bolts.

[0009] The present invention is further configured such that connecting plates are fixed on the lower end faces of the adjusting plates located on the left and right sides of the compression roller, and shafts communicating with the interior of the semi-cylindrical column are fixed on the end faces of the semi-cylindrical column. Two adjacent shafts on each compression roller are connected to form a cylindrical shape, and the two cylindrical shafts rotate through the holes on the connecting plates.

[0010] The present invention is further configured such that each shaft cylinder has an annular opening on its outer wall, and each shaft cylinder has an assembly ring fitted on its outer wall. A protruding ring is fixed inside the annular opening on the inner side of the assembly ring, and two sets of adjacent assembly rings are connected by bolts.

[0011] The present invention is further configured such that positioning rings are fitted on the outer walls of the circuit cylinders located on the left and right sides of the heating tube, and the positioning rings are slidably connected to the inner side wall of the compression roller.

[0012] The present invention is further configured such that a plurality of evenly distributed positioning cylinders are fixed on the lower end face of the U-shaped frame, and a plurality of positioning posts are fixed on the upper end face of the adjusting plate, which are respectively inserted into the corresponding positions inside the positioning cylinders. A spring is fixed on the upper end face of each positioning post to abut against the inner end face of the positioning cylinder.

[0013] This utility model has the following beneficial effects:

[0014] The metal fiber sintered felt undergoes preliminary compression by the compression rollers, putting it in a pre-compression state. Simultaneously, the heating tubes raise the temperature of the compression roller surface. Through contact between the compression rollers and the metal fiber sintered felt, the surface temperature of the metal fiber sintered felt is increased, softening the soft structure on the surface and improving the flatness of the metal fiber sintered felt.

[0015] Since the adjusting plate can move up and down inside the U-shaped frame, it will drive the compression roller to move up and down above the base plate, thus enabling the compression roller to be adaptively adjusted according to the metal fiber sintered felt. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figures 1 to 5 This utility model is a pre-compression fixture for metal fiber sintered felt. The heating pipe 207 increases the surface temperature of the compression roller 2, thereby increasing the surface temperature of the metal fiber sintered felt and softening the soft structure on the surface of the metal fiber sintered felt, making the metal fiber sintered felt flat. At the same time, through the up and down movement of the compression roller 2 inside the U-shaped frame 101, the compression roller 2 can be adaptively adjusted according to the metal fiber sintered felt.

[0026] Specifically, the base plate 1 has a U-shaped frame 101 fixed on its upper surface. Multiple sets of evenly distributed compression rollers 2 are arranged between the U-shaped frame 101 and the base plate 1. Each compression roller 2 is composed of two sets of semi-cylindrical columns. Each compression roller 2 has a circuit tube 205 inside. Each circuit tube 205 has a heating tube 207 fixed on its outer wall. An adjustment plate 3 is arranged between the U-shaped frame 101 and the compression roller 2.

[0027] The operation process of this embodiment is as follows: By setting and using the above structure, the wires on the line cylinder 205 are pulled out and connected to the power supply. Therefore, after the metal fiber sintered felt passes through the position between the base plate 1 and the compression roller 2, the heating tube 207 inside the compression roller 2 can be controlled to perform heating. At the same time, after the metal fiber sintered felt passes through the bottom of the compression roller 2, it is connected to the external traction device. The external traction device drives the metal fiber sintered felt to move. Therefore, the compression roller 2 performs preliminary compression treatment on the metal fiber sintered felt, so that the metal fiber sintered felt is in pre-compression. At the same time, the operation of the heating tube 207 increases the temperature of the surface wall of the compression roller 2. Through the contact between the compression roller 2 and the metal fiber sintered felt, the surface temperature of the metal fiber sintered felt is increased, and the soft structure of the surface of the metal fiber sintered felt is softened. At the same time, since the adjusting plate 3 can move up and down inside the U-shaped frame 101, the adjusting plate 3 will drive the compression roller 2 to move up and down above the base plate 1, so that the compression roller 2 can be adaptively adjusted according to the metal fiber sintered felt. Example 2

[0028] Please see Figure 2 , Figure 4 and Figure 5 Based on Example 1, the compression force of the compression roller 2 on the metal fiber sintered felt is increased by the spring 303 pushing the positioning column 302.

[0029] Specifically, both sides of the U-shaped frame 101 are provided with adjustment ports 102. The two ends of the adjustment plate 3 are slidably disposed in the corresponding adjustment ports 102. The end face of the adjustment plate 3 passing through the adjustment port 102 is provided with a locking strip 304 that connects with the side wall of the U-shaped frame 101. The locking strip 304 is threadedly connected to the adjustment plate 3 by bolts. The lower end face of the U-shaped frame 101 is fixed with a plurality of evenly distributed positioning cylinders 103. The upper end face of the adjustment plate 3 is fixed with a plurality of positioning pins 302 that are respectively inserted into the internal position of the corresponding positioning cylinders 103. The upper end face of the positioning pins 302 is fixed with a spring 303 that abuts against the inner end face of the positioning cylinder 103.

[0030] The operation process of this embodiment is as follows: When the compression roller 2 moves up and down, the compression roller 2 will drive the adjusting plate 3 to slide in the adjusting port 102. The adjusting plate 3 is limited by the locking strip 304 to ensure that the adjusting plate 3 can slide stably in the adjusting port 102. At the same time, the adjusting plate 3 will drive the positioning column 302 to move in the positioning cylinder 103 and compress the spring 303. Therefore, the spring 303 pushes the adjusting plate 3, which can improve the compression force of the compression roller 2 on the metal fiber sintered felt. Example 3

[0031] Please see Figure 3 and Figure 4Based on Example 1, the use of the positioning ring 206 and the shaft cylinder 201 facilitates the disassembly and assembly of the compression roller 2, thereby enabling the maintenance of the heating tube 207 therein.

[0032] Specifically, connecting plates 301 are fixed to the lower end faces of the adjusting plates 3 located to the left and right of the compression roller 2. Shaft cylinders 201 connected to the interior of the semi-cylindrical column are fixed to the end faces of the semi-cylindrical column. Two adjacent shaft cylinders 201 on each compression roller 2 are connected to form a cylindrical shape. The two cylindrical shaft cylinders 201 rotate through the openings on the connecting plates 301. The outer wall of each shaft cylinder 201 is provided with an annular opening 202. An assembly ring 203 is fitted on the outer wall of each shaft cylinder 201. A convex ring 204 is fixed inside the annular opening 202. Two sets of adjacent assembly rings 203 are connected by bolts. Positioning rings 206 are fitted on the outer wall of the line cylinders 205 located to the left and right of the heating tube 207. The positioning rings 206 are slidably connected to the inner wall of the compression roller 2.

[0033] The operation process of this embodiment is as follows: the two sets of assembly rings 203 are disassembled, so that the assembly rings 203 will not limit the shaft cylinder 201. At this time, the shaft cylinder 201 is moved to the through position on the side wall of the connecting plate 301, and the compression roller 2 can be removed from the position between the two sets of connecting plates 301. The compression roller 2 can be disassembled, and the heating tube 207 can be removed and replaced. At the same time, when the convex ring 204 is in the ring opening 202, the ring opening 202 limits the convex ring 204, thereby ensuring that the assembly ring 203 stably assembles the two sets of shaft cylinders 201, ensuring the assembly stability of the compression roller 2. At the same time, the positioning ring 206 limits the line cylinder 205, ensuring that the line cylinder 205 is stably in the compression roller 2.
