Technical Field

[0001] This utility model relates to the field of aluminum profile technology for doors and windows, and in particular to a rolling composite machine for profiles. Background Technology

[0002] The production and processing of thermally broken aluminum profiles for doors and windows requires the use of rolling technology. Rolling is a non-cutting plastic processing method. Its purpose is to reduce the surface roughness of the workpiece and improve the wear resistance, corrosion resistance and fit of the workpiece surface. The rolling spoke is the main component in the rolling composite machine that directly rolls the workpiece. It is mainly composed of three parts: the spoke body, the spoke neck and the shaft head.

[0003] Publication No. CN218743935U discloses a high-efficiency multi-functional rolling mill roll, including a roll body, a roll neck, and a shaft head; the roll neck is installed on the right end face of the roll body, the shaft head is installed on the left end face of the roll body, a connecting shaft is installed on the left end face of the shaft head, a protective ring is detachably installed on the outer wall of the connecting shaft, the outer wall of the protective ring is provided with a friction layer, the outer wall of the protective ring is symmetrically provided with positioning holes, and the bottom surface of the symmetrically arranged positioning holes is provided with through holes.

[0004] Currently, existing rolling mill spokes have the following drawbacks: they lack a detachable structure, and typically require complete replacement after prolonged use due to wear, uneven heat dissipation, and other issues, leading to increased operating costs and hindering the long-term use and development of the rolling mill. Therefore, we propose a new type of rolling mill spoke for a rolling mill. Summary of the Invention

[0005] The main purpose of this utility model is to provide a rolling composite machine for the rolling of spokes, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A roller mill spokes of a composite rolling mill include a spoke body, a sheath, and a spoke neck. The sheath is fitted around the spoke body, and a sliding groove is formed inside the spoke body. A top rod is slidably connected in the sliding groove, and an air cushion is provided on one side of the top rod in the sliding groove. A slot corresponding to the top rod is formed on the inner surface of the sheath.

[0008] Furthermore, both ends of the spoke body are provided with spoke necks, the surface of the spoke necks is provided with sealing grooves, the spoke body is provided with a flow guiding cavity, and the flow guiding cavity is connected to an air cushion. A fixing seat is fixedly provided in the sealing groove, and the air outlet end of the fixing seat is connected to the air cushion. An elastic body is provided on one side of the fixing seat, and the fixing seat is connected to the elastic body by adhesive bonding.

[0009] Furthermore, a return spring is sleeved inside the sliding groove around the top rod.

[0010] Furthermore, the air inlet end of the fixed seat is provided with a one-way valve, and the surface of the fixed seat is provided with a valve core. The fixed seat connects the one-way valve and the valve core through a slot.

[0011] Furthermore, a shaft head is provided at one end of the spoke neck.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating spokes, sheaths, sliding grooves, top rods, air cushions, and slots, a modular structure can be added. After long-term use of the spokes, the sheaths around the spokes can be replaced, reducing the cost of overall replacement and facilitating the long-term use and development of the rolling compounding machine.

[0014] With its spokes, guide cavity, fixing seat, and elastic body, the sheath can be quickly disassembled by manually pressing to inflate and deflate it. The overall structure is simple and compact, low in cost, easy to operate, more flexible and reliable in use, and has high practical value. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 and 2 As shown, a roller compounding machine for spokes includes a spoke body 1, a protective sleeve 2, and a spoke neck 14. The protective sleeve 2 is fitted around the spoke body 1. A sliding groove 3 is provided inside the spoke body 1. A top rod 4 is slidably connected inside the sliding groove 3. An air cushion 5 is provided inside the sliding groove 3 on one side of the top rod 4. A slot 12 corresponding to the top rod 4 is provided on the inner surface of the protective sleeve 2.

[0021] Both ends of the spoke body 1 are provided with spoke necks 14. A sealing groove 6 is provided on the surface of the spoke neck 14. A flow guiding cavity 13 is provided in the spoke body 1 and the flow guiding cavity 13 is connected to the air cushion 5. A fixing seat 7 is fixedly provided in the sealing groove 6 and the air outlet end of the fixing seat 7 is connected to the air cushion 5. An elastic body 8 is provided on one side of the fixing seat 7.

[0022] In this embodiment, as shown Figure 1 As shown, the spokes 14 facilitates installation with the bearing, and the rolling force is transmitted to the frame through the bearing housing and pressing device. The sealing groove 6, the fixed seat 7 and the elastic body 8 facilitate the inflation of the air cushion 5 by utilizing the elastic deformation generated by pressing.

[0023] A return spring 11 is sleeved inside the sliding groove 3 on the periphery of the top rod 4.

[0024] In this embodiment, as shown Figure 2 As shown, the return spring 11 facilitates the use of elastic force to push the top rod 4 back into the sliding groove 3 for reset.

[0025] The fixed seat 7 is provided with a one-way valve 9 at the air inlet end, and a valve core 10 is provided on the surface of the fixed seat 7.

[0026] In this embodiment, as shown Figure 3 As shown, the one-way valve 9 and the valve core 10 facilitate the control of the air entering and exiting the air cushion 5.

[0027] One end of the spoke neck 14 is provided with a shaft head 15.

[0028] In this embodiment, as shown Figure 1 As shown, the shaft head 15 facilitates the connection between the rolling spokes and the connecting shaft to transmit rolling torque.

[0029] It should be noted that this utility model is a roller pressing composite machine for spokes. During operation, the operator first puts the protective sleeve 2 on the outside of the spoke body 1 and manually presses the elastic body 8 of the fixed seat 7 in the sealing groove 6. Utilizing the elastic deformation generated by the elastic body 8, external air is drawn into the air cushion 5 through the one-way valve 9 and the guide cavity 13. The air cushion 5 is inflated and deformed, pushing the top rod 4 to slide out from the sliding groove 3 and insert into the corresponding slot 12, quickly completing the installation of the protective sleeve 2. During use, the spoke body 1 and the protective sleeve 2 are subjected to roller pressing composite processing. When the protective sleeve 2 is damaged and needs to be replaced after long-term use, the operator can release the air from the air cushion 5 through the valve core 10. Under the elastic pushing force of the return spring 11, the top rod 4 is pushed back into the sliding groove 3 to complete the retraction and reset, thereby completing the separation operation of the spoke body 1 and the protective sleeve 2. The overall structure is simple and compact, more flexible and reasonable in use, and also helps to reduce the operating cost of the roller pressing composite machine.
