Description

Technical Field

[0001] This invention relates to a processing equipment for tapered tubes with extended diameters in medium-thick plates, belonging to the technical field of machining equipment. Background Technology

[0002] The screw conveyor is an important component of a screw conveyor, and the conical screw conveyor is an important type of screw conveyor. The overall profile of a conical screw conveyor is tapered; therefore, its central shaft is also tapered. The central shaft of a conical screw conveyor is typically made of a tapered tube.

[0003] A certain type of conical spiral auger requires the use of medium-thick plates to process small-diameter, extended-length conical tubes due to parameter requirements. These conical tubes have a large length-to-diameter ratio. Due to operational requirements, segmented manufacturing is not permitted. Currently, there is no suitable equipment, either domestically or internationally, for producing medium-thick plate small-diameter extended conical tubes. Therefore, in response to customer requirements, a processing equipment for medium-thick plate diameter extended conical tubes was manufactured. Summary of the Invention

[0004] The purpose of this invention is to provide a processing equipment for tapered tubes with extended diameters made of medium-thick plates, in order to solve the problem of processing tapered tubes with large length-to-diameter ratios using medium-thick plates.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A processing equipment for tapered tubes with extended diameters of medium-thick plates includes a base platform, a lower tapered tube mold mounted on the base platform, and several pressing components arranged along the length of the lower tapered tube mold; it also includes an upper tapered tube mold; the tapered tube mold is pressed down by the pressing components and cooperates with the lower tapered tube mold to form the tapered tube arc plate; each pressing component presses down synchronously.

[0007] A further improvement to this technical solution is that the pressing assembly includes a pressing rod, an upper frame plate, and at least two support rods; the lower end of the support rod is fixed to the base platform and located on both sides of the lower die of the conical tube, and the upper frame plate is fixed to the upper end of the support rod; the pressing rod is fixed to the lower end face of the upper frame plate and is set downward, and the telescopic end of the pressing rod performs the pressing action.

[0008] A further improvement to this technical solution is that a lower pressure plate is fixedly installed at the telescopic end of the lower pressure rod.

[0009] A further improvement to this technical solution is that the base platform is provided with several mounting holes for cooperating with the support rod, and the support rod is installed in the corresponding position as needed.

[0010] A further improvement to this technical solution is that the lower mold of the conical tube is formed by welding together a base plate, a vertical plate, a reinforcing plate, and a stiffening plate; the vertical plate is provided with a tapered inner cavity; the reinforcing plate and stiffening plate are welded to the side of the vertical plate, and the reinforcing plate and stiffening plate are also welded and fixed to the base plate.

[0011] A further improvement to this technical solution is that the lower mold of the conical tube is set in segments, and the taper of the inner cavity of the vertical plate of each segment of the lower mold of the conical tube is consistent.

[0012] A further improvement to this technical solution is that the base platform includes two sets of steel profiles arranged opposite each other and a steel plate fixed on the steel profiles, with several through holes provided at the edge of the steel plate as mounting holes.

[0013] A further improvement to this technical solution is that it also includes an upper mold for the conical tube; the upper mold for the conical tube is controlled by the pressing component to press down and cooperate with the conical tube mold to extrude and form the second conical tube arc plate; the conical tube mold and the upper mold for the conical tube are placed sequentially as needed.

[0014] A further improvement to this technical solution is that the pressure rod is a hydraulic cylinder.

[0015] Due to the adoption of the above technical solution, the technical effects achieved by this invention are as follows:

[0016] The present invention sets up a conical tube lower mold and a conical tube mold for use on a base platform. After the semi-conical extended tube is unfolded and placed between the conical tube lower mold and the conical tube mold, the semi-conical tube can be pressed into shape by pressing the conical tube mold by the pressing component. Then, the small-diameter extended conical tube can be produced by the axial welding process.

[0017] This invention can also include a conical tube upper mold, which allows for the pressing of two semi-conical extended tubes in a single process. After the first semi-conical extended tube is pressed, the second semi-conical extended tube is directly machined. The two semi-conical extended tubes are pressed into shape through the cooperation between the conical tube upper mold and the conical tube mold. After the two semi-conical extended tubes are pressed, spot welding can be performed on the equipment to form a preliminary connection structure, facilitating subsequent welding. This eliminates the need for butt welding of the two semi-conical extended tubes, thus improving overall work efficiency.

[0018] In this invention, the pressing component is mounted on the base platform via a support rod. The support rod is installed in a detachable manner, allowing it to be installed at the appropriate position as needed. This enables the pressing component to be installed at different positions along the axial direction of the lower die of the conical tube according to the requirements of different conical tube parameters.

[0019] In this invention, the upper mold for the conical tube is segmented, and the taper of the inner cavity of each segment of the upper mold is consistent. The upper mold for the cylindrical tube of the corresponding length can be assembled and set according to the actual length of the conical tube to be processed. The number of pressing components is also installed according to actual needs.

[0020] This invention solves the problem of machining conical tubes with a large length-to-diameter ratio using medium-thick plates, and improves the overall machining efficiency. Attached Figure Description

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] This invention relates to a processing equipment for medium-thick plate diameter extended tapered tubes, used to process medium-thick plate small-diameter extended tapered tubes. This type of tapered tube is characterized by a large length-to-diameter ratio. Tapered tubes are an important component of spiral augers. The processing equipment of this invention forms two semi-tapered tubes by pressing them together with a mold, and then achieves the production of small-diameter extended tapered tubes through axial welding.

[0031] like Figures 1-7As shown, the equipment mainly includes a base platform 1, a pressing assembly, a lower conical tube mold 2, an upper conical tube mold 3, and a conical tube mold 4, wherein the upper conical tube mold 3 is an optional part. The lower conical tube mold 2 has a tapered inner cavity and can be considered as half of a conical tube. The upper conical tube mold 3 also has a tapered inner cavity and can be considered as half of a conical tube. The conical tube mold 4 is an integral conical tube structure.

[0032] The conical tube lower mold 2 is fixedly installed on the base platform 1. Multiple pressing components are provided, and the pressing components are arranged sequentially along the length direction of the conical tube lower mold 2.

[0033] During use, the conical tube mold 4 is pressed down by the pressing assembly, which cooperates with the lower conical tube mold 2 to form the conical tube arc plate. During operation, all pressing assemblies need to maintain synchronous pressing to ensure uniform force application. Two extended semi-conical tubes are formed by pressing down two semi-conical extended tube unfolding plates, and then the two extended semi-conical tubes are welded together to form a single extended conical tube.

[0034] like Figure 4 , Figure 5 As shown, in specific implementation, the pressing assembly includes a pressing rod 5, an upper frame plate 6, and at least two support rods 7. Generally, two support rods 7 are provided, located on both sides of the lower conical tube mold 2. The lower ends of the support rods 7 are fixedly installed on the base platform 1, and the upper frame plate 6 is fixedly installed on the upper ends of the support rods 7, keeping the upper frame plate 6 in a horizontal state. The pressing rod 5 is fixed to the lower end face of the upper frame plate 6. The pressing rod 5 is generally downward-facing, and its telescopic end specifically performs the pressing action, moving downward to apply force during pressing. Furthermore, a pressing plate 8 is fixedly installed at the telescopic end of the pressing rod 5, which contacts the conical tube mold 4, thereby pressing down on the conical tube mold 4, and subsequently, the conical tube mold 4 presses down on the conical tube arc plate.

[0035] Several pressing components are set. Since the conical tube mold 4 has a certain taper, the starting height position of the pressing rod 5 of the pressing component is not on a horizontal line but matches the taper of the conical tube mold 4, and maintains matching with the conical tube mold 4 during the pressing process.

[0036] In this invention, the pressing assembly is mounted on the base platform via a support rod 7. Preferably, the support rod 7 is installed in a detachable manner, allowing it to be installed at appropriate positions as needed. This enables the pressing assembly to be installed at different positions along the axial direction of the lower die 2 of the conical tube, depending on the required parameters of different conical tubes. Specifically, several mounting holes 9 are provided on the base platform 1, which are used to mate with the support rod 7, allowing the support rod 7 to be installed within the corresponding mounting holes 9. For example, a nut can be used for fixing.

[0037] In this invention, the lower mold 2 of the conical tube is a mold that enables the lower arc plate of the conical tube to be formed. For example... Figure 7 As shown, the structure of the conical tube lower mold 2 includes a base plate 2-1, a vertical plate 2-2, a reinforcing plate 2-3, and a stiffening plate 2-4. These plates are made of steel and are connected to each other by welding. The vertical plate 2-2 has a tapered inner cavity; the reinforcing plate 2-3 and stiffening plate 2-4 are welded to the side of the vertical plate 2-2 and then fixed to the base plate 2-1 by welding.

[0038] Furthermore, the lower conical tube mold 2 is preferably segmented, with the inner cavities of the vertical plates 2-2 of each segment of the lower conical tube mold 2 having the same taper. Each segment of the lower conical tube mold 2 is welded and fixed to the base plate 2-1 by the reinforcing plates 2-3 and ribs 2-4 of each segment. The upper conical tube mold 3 and the conical tube mold 4 can also adopt a segmented structure.

[0039] In this invention, the base platform 1 functions as a base. Specifically, the base platform 1 includes two sets of opposing steel profiles and steel plates. The steel plates are fixed to the steel profiles, and several through holes 9 are provided at the edges of the steel plates as mounting holes. The steel profiles used here can be I-beams. The steel plates are mounted on the steel profiles, thus creating an open structure at the bottom of the steel plates, providing working space for the installation of the support rods 7 and the base platform 1.

[0040] In specific implementations of this invention, the lowering rod 5 is preferably selected as a hydraulic cylinder, and a hydraulic pump station is correspondingly configured. The hydraulic cylinder pressurizes smoothly and can provide sufficient pressure.

[0041] The above-mentioned equipment of the present invention uses a conical tube lower mold 2 and a conical tube mold 4 to press down and form two semi-conical extended tubes respectively. The two semi-conical extended tubes are processed by two pressing actions. Then, the two semi-conical extended tubes are accurately joined together and welded to form a complete extended conical tube.

[0042] This invention also includes an optional upper conical tube mold 3, with the lower conical tube mold 2 and upper conical tube mold 3 having the same structure. The difference lies in that the lower conical tube mold 2 is fixed to the base platform 1, while the upper conical tube mold 3 is an independent semi-conical tube placed in the appropriate position during use. The upper conical tube mold 3 is pressed down by the pressing component, working in conjunction with the conical tube mold 4 to form the upper arc plate of the conical tube. By using the upper conical tube mold 3, the second semi-conical extended tube can be processed without removing the first semi-conical extended tube. After both semi-conical extended tubes are pressed and formed, spot welding is performed on the equipment to form a preliminary connection structure, facilitating subsequent welding processing.

[0043] During operation, the conical tube mold 4 and the upper conical tube mold 3 need to be placed sequentially as required. Specifically, first, the prepared semi-conical extended tube unfolded sheet is placed between the lower conical tube mold 2 and the conical tube mold 4. Then, the lowering rod 5 on the lowering assembly drives the lowering plate 8 to apply downward force, thereby causing the conical tube mold 4 to move downward. During operation, each lowering assembly should apply force reasonably according to the deformation of the semi-conical tube to ensure uniform force distribution during the manufacturing process. After the first tapered extension plate is formed, the second semi-tapered extension tube is placed on the tapered tube mold 4. Then, the upper tapered tube mold 3 is placed on the second semi-tapered extension tube. At this point, the lower pressure rod 5 drives the lower pressure plate 8 to press down on the upper tapered tube mold 3, thus pressing the second semi-tapered extension tube. After ensuring accurate positioning, the lower pressure rod 5 applies downward force. After pressing down, the second semi-tapered extension tube is completed, and the two semi-tapered extension tubes are in a mating state. Workers can slightly adjust the two semi-tapered extension tubes as needed. After adjustment, the mating joint of the two semi-tapered extension tubes is spot-welded for fixation. Then, the entire tapered extension tube is removed for subsequent welding processing. Because it is a tapered tube, and the tapered tube mold is also a tapered tube, the tapered tube mold can be removed from the large-diameter end of the overall tapered extension tube structure.

[0044] In the above process, in order to maintain balance, support frames can be set at both ends of the base platform to support the second semi-conical extended tube unfolding plate and maintain balance. It is preferable to set the support frame to be a liftable structure. Especially at the beginning of the pressing down, the support frame needs to support the second semi-conical extended tube unfolding plate while also descending synchronously with the pressing component.

[0045] This invention enables the fabrication of small-diameter extended tapered tubes using medium-thick plates, resulting in tubes with a large length-to-diameter ratio. The invention utilizes a lower and a higher conical tube mold to press two semi-conical tubes together, allowing for axial welding to create the small-diameter extended tapered tube. Furthermore, by using an upper conical tube mold, two semi-conical extended tubes can be pressed in a single process. After pressing, spot welding can be performed on the equipment to form a preliminary connection between the two tubes, facilitating subsequent welding.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
