Positioning mold, special-shaped gas collecting pipe rolling device and rolling method

Abstract

The present application discloses a positioning mold, a rolling device and a rolling method for a special-shaped gas collecting pipe. The positioning mold includes: a positioning body having at least one positioning surface for contacting the blank to be rolled; an adjusting member that is telescopically movable relative to the positioning body; and a positioning protrusion that is arranged on the adjusting member to press the blank through the telescopic movement of the adjusting member until the positioning surface is fully positioned on the blank. In this technical solution, when implementing the rolling operation, it is only necessary to replace the pressure roller originally installed on the pressure roller shaft with the positioning mold, and the positioning mold is used to press the blank to form the special-shaped part. Then, a pressure roller is installed on the pressure roller shaft, and the pressure roller is used to press the blank to form the non-special-shaped part, thereby completing the rolling operation of the gas collecting pipe. Since in this rolling operation, the positioning mold is only selectively installed on the pressure roller shaft, the need to separately implement the processing steps of forming the special-shaped part in the related art is avoided, reducing the complexity of the processing.

Description

Technical Field

[0001] The present application relates to the technical field of gas collecting pipes, and in particular to a positioning mold, a rolling device and a rolling method for special-shaped gas collecting pipes. Background Art

[0002] In coke oven construction, the furnace roof gas collector, a core piping component of the coking process, is crucial for the fabrication of large-diameter, special-shaped pipes. Furthermore, fabrication precision and quality directly impact the quality of coal chemical products. According to design requirements, fabricating large-diameter, special-shaped gas collectors is difficult and time-consuming, and accuracy and quality are challenging. Based on the construction characteristics of coke oven gas collectors and incorporating field experience, a device capable of rolling large-diameter, special-shaped gas collectors was developed.

[0003] In the related art, the common processing method for rolling special-shaped gas collecting pipes is to first use a rolling device to roll the whole pipe into a circular shape, and then use other equipment to press the local position of the circular gas collecting pipe to form the special-shaped part. This makes the rolling process more complicated. Summary of the Invention

[0004] In view of this, the present application provides a positioning mold, a rolling device and a rolling method for a special-shaped gas collecting pipe, which reduces the complexity of rolling.

[0005] In a first aspect, the present application provides a positioning mold, comprising:

[0006] a positioning body having at least one positioning surface for contacting the blank to be rolled;

[0007] an adjusting member configured to telescopically move relative to the positioning body;

[0008] and a positioning protrusion fixedly arranged on the adjustment member to press the blank through the telescopic movement of the adjustment member until the positioning surface is fully positioned on the blank.

[0009] Optionally, the positioning body is constructed to be trapezoidal in shape as a whole.

[0010] Optionally, the positioning surface is inclined at an angle of 120-165° relative to the telescopic movement direction of the adjusting member.

[0011] In a second aspect, the present application provides a method for rolling a special-shaped gas collecting pipe, comprising a positioning mold as described above that can be selectively installed on a pressure roller shaft.

[0012] Optionally include:

[0013] A power member, used for driving the pressure roller shaft;

[0014] At least one fixed roller is configured to support the blank when the pressing roller shaft is driven, so as to cooperate with a positioning module installed on the pressing roller shaft to press the blank until rolling is completed.

[0015] In a third aspect, the present application provides a method for rolling a special-shaped gas collecting pipe, which uses the above-mentioned rolling device to roll the blank.

[0016] The above-described positioning die, rolling device, and rolling method for a special-shaped manifold are provided. During the rolling operation, the roller originally mounted on the pressure roller shaft is replaced with the positioning die. The positioning die presses the blank to form the special-shaped portion. The pressure roller is then reinstalled on the pressure roller shaft and presses the blank to form the non-special-shaped portion, thus completing the rolling operation of the manifold. Since this rolling operation only involves the selective installation of the positioning die on the pressure roller shaft, the need for a separate process for forming the special-shaped portion, as in related technologies, is avoided, reducing the complexity of the process.

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] Before introducing the technical solution of this application, it is necessary to explain the background of the invention of this application.

[0032] It is common in the related art to roll a special-shaped manifold. The common processing method is to first use a rolling device to roll the circular manifold 10 into an overall circular shape, and then use other equipment to process the circular manifold 10 at a local position to form the special-shaped portion 11. Since the processing step of forming the special-shaped portion 11 requires the use of additional processing equipment, in actual operation, this will undoubtedly lead to the blank 900 being unloaded from a workstation, transferred, and then entered into another workstation. This undoubtedly increases the complexity of the entire processing process and reduces processing efficiency.

[0033] Based on the inventors' awareness of the above-mentioned difficulties, the inventors have proposed a rolling device and method for a positioning mold 100 and a special-shaped gas collecting pipe. During the rolling operation, it is only necessary to replace the pressure roller 310 originally installed on the pressure roller shaft 300 with the positioning mold 100. The positioning mold 100 can press the blank 900 to form the special-shaped portion 11. Then, the pressure roller 310 is restored to the pressure roller shaft 300, and the pressure roller 310 can press the blank 900 to form the non-special-shaped portion 12, thereby completing the rolling operation of the gas collecting pipe. Because in this rolling operation, only the positioning mold 100 is selectively installed on the pressure roller shaft 300, the need to separately implement the processing step of forming the special-shaped portion 11 in the related art is avoided, reducing the complexity of the processing. Thus, the present invention was created.

[0034] refer to Figure 2 , an embodiment of the present application provides a rolling device for a special-shaped gas collecting pipe, including a positioning mold 100 that can be selectively installed on a pressure roller shaft 300.

[0035] It should be understood that the term "optionally mounted" here means that the positioning mold 100 is not the only one mounted on the pressure roller shaft 300 during operation. Specifically, as previously described, the positioning mold 100 is mounted on the pressure roller shaft 300 only when required to form the deformed portion 11. When the pressure roller shaft 300 is in operation to form the non-deformed portion 12, the pressure roller 310 is mounted on the pressure roller shaft 300.

[0036] As a way to implement selective installation, based on the need for convenient disassembly and assembly, conventional detachable structures in the field can be adopted, such as screw connection, clip connection, etc., which is completely within the general design capabilities of technical personnel in the relevant field.

[0037] The above-mentioned rolling device can completely adopt a rolling machine known in the art for forming the gas collecting pipe 10. Of course, the pressure roller shaft 300 of the known rolling machine can be conventionally designed to achieve its detachability.

[0038] Reference again Figure 2 As an exemplary implementation, the rolling device includes:

[0039] A power member 200 for driving the pressure roller shaft 300;

[0040] At least one fixed roller 400 is configured to support the blank 900 when the pressing roller shaft 300 is driven, so as to cooperate with a positioning module installed on the pressing roller shaft 300 to press the blank 900 until rolling is completed.

[0041] The rolling mechanism of the above-described structure is as follows: a blank 900, which can be a metal plate of a desired material, is placed on the fixed roller 400. The power element 200 is activated, and the pressure roller shaft 300, driven by the power element 200, moves toward the fixed roller 400 until the pressing component on the pressure roller shaft 300 (designated as the positioning mold 100 or the pressure roller 310) contacts and presses the blank 900. Because the fixed roller 400 supports the blank 900, the pressing component deforms the blank 900 to complete the rolling process.

[0042] Please refer again Figure 2 When the pressing member is the positioning mold 100, the positioning mold 100 can form the special-shaped portion 11. Figure 1 When the pressing component is a pressing roller 310, a normal non-special-shaped portion 12 is formed.

[0043] Here, the power component may be a hydraulic cylinder, or other forms.

[0044] The number of fixed rollers 400 may be as follows: Figure 1 Two are shown, and of course different quantities can be selected according to actual needs.

[0045] Since the fixed roller 400 and the nip roller are well known in the art, their shapes, sizes or structures are not described in detail herein.

[0046] It is easy to imagine that the fixed roller 400 and the pressing material can be installed on the base 700. In order to operate the pressing roller shaft 300, a fixed handle 500 can be installed on the pressing roller shaft 300.

[0047] refer to Figure 2 、 Figure 5 and Figure 6 , the positioning mold 100 includes:

[0048] A positioning body 120 having at least one positioning surface 120a for contacting the blank 900 to be rolled;

[0049] an adjusting member 130 , configured to telescope relative to the positioning body 120 ;

[0050] A positioning protrusion 140 is fixedly configured on the adjustment member 130 to press the blank 900 through the telescopic movement of the adjustment member 130 until the positioning surface 120 a is fully positioned on the blank 900 .

[0051] The positioning mold 100 of the above structure produces the working principle of the shaped portion 11 as follows: operate the adjusting member 130, even if it is moved along the Figure 2 As shown, the positioning protrusion 140 contacts and finally presses the blank 900. Since the blank 900 is supported on the fixed roller 400, under the pressure of the positioning protrusion 140, the blank 900 moves relative to the adjustment member 130 in the direction of expansion and contraction (i.e. Figure 2 The positioning body 120 is driven by the power component, and the positioning surface 120a is driven by the power component. The positioning surface 120a will produce an extrusion pressing action on the blank 900 as the positioning body 120 is driven. It should be noted that since the positioning protrusion 140 is always pressed against other positions of the blank during the pressing action of the positioning surface 120a, the positioning protrusion 140 is prevented from causing the blank 900 to slide as a whole due to the pressing of the positioning surface 120a. Of course, it is easy to realize that the positioning protrusion does not only prevent the blank 900 from sliding as a whole. Since the positioning protrusion will also move relative to the blank 900 as the positioning body 120 is driven, the positioning protrusion will produce an extrusion action on the blank 900, thereby producing pressing at another position.

[0052] That is to say, the pressing of the positioning surface 120a and the pressing of the positioning protrusion form a mutual cooperation from beginning to end (that is, whether before the positioning body 120 is driven or during the entire process of the positioning body 120 being driven) to complete the operation of forming the blank 900 into the special-shaped part 11.

[0053] The positioning body 120 may be in the form of a pin, and its shape may be trapezoidal.

[0054] Here, the specific trapezoidal shape is conducive to forming a strong extrusion force on the blank 900, thereby forming it better.

[0055] As an exemplary implementation, the positioning body 120 has a top surface that is wider at the top, a bottom surface that is narrower at the bottom, and two positioning surfaces 120 a located on both sides.

[0056] The shape of the positioning surface 120 a can be a flat surface, or can be conventionally adjusted according to the shape required by the actual shaped portion 11 .

[0057] Reference Figure 3 and Figure 4The positioning surface 120a is inclined at an angle of 120-165° relative to the telescopic movement direction of the adjusting member 130.

[0058] In this way, the forming accuracy can be improved.

[0059] As an exemplary implementation of the positioning protrusion 140, it can be any protrusion, such as a round rod, a sphere, a square block, or a Figure 7 Round steel tube form shown.

[0060] The adjusting member 130 may be a bolt member. In this case, the positioning body 120 is configured with a screw hole.

[0061] As another implementation of the adjusting member 130, the bolt member can also be replaced with a rod, and the positioning body 120 is configured with a non-threaded socket. In order to facilitate the fixing of the adjusting member 130 in this implementation, a stopper (not shown) can also be configured.

[0062] As another implementation of the adjusting member 130 (not shown in the figure), the adjusting member 130 is an electric push rod, a pneumatic push rod, a hydraulic push rod, etc.

[0063] Now, the operation process of the rolling of the present application will be described in a common application scenario. It should be noted that this common implementation scheme cannot be used as a basis for understanding the essential features of the technical problem claimed to be solved by the present application, and it is only an example.

[0064] The rolling operation process of the gas collecting pipe 10 is as follows:

[0065] S1. Replace the pressure roller 310 on the pressure roller shaft 300 of the tube reel with the positioning mold 100.

[0066] S2. Place the steel plate (i.e., the blank 900 ) into the accommodation space surrounded by the pressing roller 310 and the fixing roller 400 .

[0067] S3. The hydraulic cylinder (i.e., the power member 200 ) is opened, and the positioning die 100 is driven downward to press the steel plate into the special-shaped portion 11 .

[0068] S4 , loosen the positioning mold 100 , lift the steel plate with the special-shaped portion 11 , and replace the positioning mold 100 with the pressing roller 310 .

[0069] S5, use the guide chain to move the steel plate, according to the layout, press the roller 310 down, and start rolling to form a circular part until the gas collecting pipe 10 is finally obtained, refer to Figure 6 .

[0070] S6. Close and weld the gas collecting pipe 10 and the cross support 13.

[0071] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
