Description

Technical Field

[0001] This utility model relates to flue forming machine technology, and in particular to a multi-hole pipe forming machine. Background Technology

[0002] Thin-walled tubes have a wide range of applications in the construction industry, especially in the smoke exhaust ducts of residential buildings. In recent years, many manufacturers have tried to use integrated internal and external molds to produce smoke ducts, which has greatly improved the strength of the smoke ducts, but there are still many problems.

[0003] CN202491297U discloses an inner mold structure for a square thin-walled tube forming machine. This inner mold structure includes a rectangular frame composed of upper and lower wall panels and left and right wall panels. A drive shaft is located within the rectangular frame, and a limit tube is fitted onto the drive shaft. The drive shaft has multiple inner mold tensioning components, each including an inner mold roller, a track plate, a positioning plate, and an inner mold pull plate. The track plate is welded and fixed to the positioning plate at both ends. The inner mold roller is positioned in the center track of the track plate. The inner mold pull plate and the inner mold roller are connected by bolts or pins. The inner mold pull plate is connected to the upper and lower wall panels and the left and right wall panels by flat-head bolts. The inner mold tensioning components can be single-track, double-track, or multi-track structures. A transmission device drives the drive shaft to reciprocate, causing the inner mold roller in the inner mold tensioning components to move along the grooves in the track plate, creating a pulling force on the inner mold pull plate. The upper and lower wall panels and the left and right wall panels achieve the inner mold tensioning movement under the pull of the inner mold pull plate. Currently, there is no molding machine that can produce porous flues, and the inner mold is difficult to demold, resulting in high labor intensity, high energy consumption, low automation, and low yield.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0024] like Figure 1 and 2 As shown, a multi-hole pipe forming machine includes an inner mold, an outer mold, and a machine head. The inner mold is located inside the outer mold. The outer frame of the inner mold has a rectangular structure. The two side plates of the outer mold are connected by fixing rods to form a U-shaped structure. The gap between the inner mold and the outer mold is used to fill the mixed mortar used to make the pipe. The inner mold includes a main channel inner mold and a secondary channel inner mold. A gap is left between the main channel inner mold and the secondary channel inner mold. The cross-section of the secondary channel inner mold is triangular, and the cross-section of the main channel inner mold is polygonal. The two main channel inner molds and one secondary channel inner mold are arranged in a triangular shape. One end of the two main channel inner molds is connected to a first machine head, and one end of the secondary channel inner mold is connected to a second machine head. Fixtures are provided at both ends of the inner mold.

[0025] like Figure 3As shown, a support is fixed to the bottom of the main channel inner mold, and a top rod passes through the pipe hole on the support. The top rod moves in the pipe hole. A first track plate and a pulley frame are fixed on the top rod. The top plate of the main channel inner mold is connected to the upper part of the support wheel assembly. The lower part of the support wheel assembly is provided with support wheels. The track of the first track plate is not parallel to the top plate of the main channel inner mold. The support wheels slide in the track. The pulleys on the pulley frame are in contact with the inner wall of the side plate of the main channel inner mold. The first machine head is connected to the bottom of the main channel inner mold through a first connecting plate. The top rod is connected to the drive mechanism.

[0026] The polygon is a pentagon with two sets of relatively parallel pentagons, and the interior angles of the pentagons include three right angles.

[0027] like Figure 4 As shown, the inner mold of the secondary channel includes a second connecting plate, a support frame, a second runway plate, a push-pull rod, and an outer inner mold plate. A support frame is fixed to the top inner wall of the outer inner mold plate. Support wheels are provided at the bottom of the support frame, and these wheels slide on the runway of the second runway plate. The support frame is connected to the second machine head via the second connecting plate. The push-pull rod is connected to the second runway plate and moves back and forth. One end of the push-pull rod is provided with a support member located at the opening of the outer inner mold plate. The push-pull rod is connected to a drive device. The support member is circular.

[0028] A vibrator is installed on the frame at the bottom of the inner mold, and an elastic support is provided at the bottom of the outer mold.

[0029] Implementation process: After the first machine head drives the main channel inner mold into the outer mold, the second machine head drives the auxiliary channel inner mold into the predetermined position of the outer mold. The outer mold is then secured with a netting and locked by a fixing rod. A fixture is then placed to fix the main channel inner mold and the auxiliary channel inner mold. Figure 5 As shown, the drive mechanism moves the push rod, which in turn moves the first track plate. The support wheel slides in the ramp track, causing the support wheel assembly to apply outward force to the top plate of the main channel inner mold. Simultaneously, the pulley applies outward force to the side plate of the main channel, achieving the opening effect of the main channel inner mold. The drive mechanism moves the push-pull rod, which in turn moves the second track plate. The support wheel slides in the ramp of the second track plate, causing the support frame to apply outward force to the top of the inner mold outer plate. At the same time, the circular support at one end of the push-pull rod is inserted into the opening of the inner mold outer plate, achieving the opening effect of the secondary channel inner mold. Then, mixed mortar is poured into the gaps between the inner and outer molds, and between the main channel inner mold and the secondary channel inner mold. The vibrator is then activated to compact the mortar and smooth the top. After the pipes solidify, the push rod and push rod return to their original positions under the action of the drive mechanism. The deformation and rebound of the main channel inner mold and the secondary channel inner mold achieve shrinkage. Figure 6As shown, the two machine heads respectively drive the main duct inner mold and the secondary duct inner mold to pull out of the pipe. After the pipe is removed, the production process of the next pipe is carried out. Example

[0030] Unlike Example 1, as Figure 7 As shown, the secondary channel inner mold includes an inner mold outer plate, and an expansion air pipe is provided at the opening of the inner mold outer plate. The expansion air pipe is connected to an air pump. An arc-shaped fixing member is provided on the outer side of the expansion air pipe, and the arc-shaped fixing member is fixed to the inner wall of the opening of the inner mold outer plate.

[0031] Implementation process: After the first machine head drives the main channel inner mold into the outer mold, the second machine head drives the auxiliary channel inner mold into the predetermined position of the outer mold. The outer mold is then secured with a netting and locked by a fixing rod. A fixture is then placed to fix the main channel inner mold and the auxiliary channel inner mold. Figure 5 As shown, the drive mechanism moves the push rod, which in turn moves the first track slab. The support wheel slides in the inclined track, causing the support wheel assembly to apply outward force to the top plate of the main channel inner mold. Simultaneously, the pulley applies outward force to the side plate of the main channel, achieving the opening effect of the main channel inner mold. The air pump inflates the expansion pipe, which then expands and opens the opening of the outer plate of the inner mold, achieving the opening effect of the secondary channel inner mold. Then, mixed mortar is poured into the gaps between the inner and outer molds, and between the main channel inner mold and the secondary channel inner mold. The vibrator is then activated to compact the mortar and smooth the top. After the pipes solidify, the push rod and push rod return to their original positions under the action of the drive mechanism. The main channel inner mold deforms and springs back to shrink, the air pump releases air, and the secondary channel inner mold deforms and springs back to shrink. Figure 6 As shown, the two machine heads respectively drive the main duct inner mold and the secondary duct inner mold to pull out of the pipe. After the pipe is removed, the production process of the next pipe is carried out.
