Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe forming machines, in particular to a forming machine with a sheet-type frame structure which can process steel pipes of any length. Background Art

[0002] At present, large steel pipes are usually processed by steel pipe forming machines, which have high processing efficiency and low cost. With the continuous progress of the times, the most commonly used in the existing technology is the heavy-duty bending press forming machine with archway-style columns. It adopts an integrated archway-style structure, which is compact and has good working reliability. However, this equipment has certain limitations on the length of steel pipe processing. The workbench can usually only process steel pipes with a maximum length of 16 meters. For steel pipes longer than 18 meters, if the forming machine structure is still used for processing, the size and weight of the workbench and the upper beam need to be greatly increased, which will become very bulky and the manufacturing cost is extremely high. It has no market competitiveness. In addition, it also brings relatively large troubles to the lifting, transportation, assembly and other tasks. Utility Model Content

[0003] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a forming machine with a sheet-type frame structure that can process steel pipes of any length, thereby effectively solving a series of problems such as equipment transportation, equipment installation and lifting, and user factory building height. It can flexibly process steel pipes of various lengths and sizes and is flexible and convenient to use.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A forming machine with a sheet frame structure that can process steel pipes of any length includes a foundation with a pit dug therein. A plurality of gantries are evenly spaced from one end to the other in the pit. A conveying roller device for conveying steel plates is provided on the inner side of all the gantries. An oil cylinder is fixedly installed on the top of a single gantry by fasteners. A heavy-duty connecting slider is also installed on the output end of all the oil cylinders. An upper mold is installed on the bottom of the connecting slider by fasteners. The head of the upper mold is a pressure head. A fixed seat is installed below all the gantries at the same time. A lower mold matching the upper mold is installed on the top surface of the fixed seat.

[0006] As a further improvement of the above technical solution:

[0007] The structure of each gantry is the same.

[0008] A flexible connection is used between the bottom of a single gantry and the foundation.

[0009] The bottom of a single gantry is connected to the foundation by disc springs and fasteners.

[0010] A sliding connection mechanism is provided between the two groups of gantries located at the end portions.

[0011] The specific structure of the sliding connection mechanism is: it includes a guide rail seat, one end of the guide rail seat is fixed to the gantry on the corresponding side by a fastener, the other end of the guide rail seat is installed with a guide rail plate, the guide rail plate is cooperated with the slider installed, and the slider is fixed to the gantry on the corresponding side by screws.

[0012] The slider is a right-angle structure.

[0013] A fixed connection mechanism is provided between adjacent gantries located in the middle.

[0014] The specific structure of the fixed connection mechanism is: it includes a fixed support with an "I"-shaped structure, the two ends of the fixed support are locked between the two adjacent gantries by fasteners, and support rods are respectively provided above and below the fixed support, and the two ends of the support rods are fixed between the two adjacent gantries.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model has a compact and reasonable structure and is easy to operate. By redesigning the forming machine, it is designed into a sheet-type frame structure. The number of gantries can be increased or decreased according to the length of the steel pipe, so as to meet the needs of forming and processing steel pipes of any length without increasing the size and weight of the equipment. The overall working flexibility and working reliability are good.

[0017] The utility model is also designed with a sliding connection mechanism, which can ensure stability when processing longer steel pipes. Sliding can be generated between the stressed gantry and the unstressed gantry, thereby ensuring the reliability of the entire equipment.

[0018] The utility model is designed with a fixed connection mechanism to ensure the stability between two adjacent gantries. A flexible connection is adopted between the gantries and the ground plane to allow the gantries to slide within the compression range of the disc spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0030] like Figure 1-Figure 7 As shown, the forming machine of the sheet frame structure of the present embodiment, which can flexibly process pipes of arbitrary lengths, includes a foundation 1 with a pit dug therein, and a plurality of gantries 2 (nine gantries 2 in the present embodiment) are evenly spaced from one end to the other in the pit, and a conveying roller device for conveying steel plates is provided on the inner side of all the gantries 2. A cylinder 3 is fixedly installed on the top of a single gantry 2 by fasteners, and a heavy-duty connecting slider 4 is also installed on the output end of all the cylinders 3. An upper mold 5 is installed on the bottom of the connecting slider 4 by fasteners, and the head of the upper mold 5 is a pressure head 6. A fixing seat 8 is also installed below all the gantries 2, and a lower mold 7 matching the upper mold 5 is installed on the top surface of the fixing seat 8.

[0031] Each gantry 2 has the same structure.

[0032] A flexible connection is adopted between the bottom of a single gantry 2 and the foundation 1 .

[0033] The bottom of a single gantry 2 is connected to the foundation 1 by using disc springs 9 and fasteners.

[0034] A sliding connection mechanism 10 is provided between the two groups of gantries 2 at the end portions.

[0035] The specific structure of the sliding connection mechanism 10 is: it includes a guide rail seat 1004, one end of the guide rail seat 1004 is fixed to the gantry 2 on the corresponding side by a fastener, the other end of the guide rail seat 1004 is installed with a guide rail plate 1003, the guide rail plate 1003 is cooperated with the slider 1001 to be installed, and the slider 1001 is fixed to the gantry 2 on the corresponding side by a screw 1002.

[0036] The slider 1001 has a rectangular structure.

[0037] A fixed connection mechanism 11 is provided between adjacent gantries 2 located in the middle.

[0038] The specific structure of the fixed connection mechanism 11 is: it includes a fixed support 1102 with an "I"-shaped structure, and the two ends of the fixed support 1102 are locked between the two adjacent gantries 2 through fasteners. Support rods 1101 are also provided above and below the fixed support 1102, and the two ends of the support rod 1101 are fixed between the two adjacent gantries 2.

[0039] In the process of processing steel pipes in this embodiment, the raw material is a large flat plate, which is gradually transported by the conveying mechanism and continuously forged through the cooperation between the upper die 5 and the lower die 7 until a circular structure is formed, and then transported to the next process for welding.

[0040] When the workpiece being bent is 9 meters long, only five gantries 2 are required to bear the load. Finite element analysis and the load conditions show that the other four gantries 2, unloaded, will move upward, causing slippage between the loaded and unloaded gantries 2. To address this issue, a sliding connection is implemented between the loaded and unloaded gantries 2 to ensure slippage. Furthermore, each gantries 2 is flexibly connected to the ground, allowing for slippage within the compression range of the disc springs 9.

[0041] The utility model can freely select which gantries 2 to use according to the length of the steel pipe that needs to be processed, and has good overall working flexibility and good working reliability.

[0042] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
