Description

Technical Field

[0001] This utility model relates to the field of aging furnace structure technology, and in particular to a stepping frame moving device for a continuous aging furnace. Background Technology

[0002] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry, and are extensively used in aerospace, automotive, machinery manufacturing, shipbuilding, construction, decoration, and chemical industries. After production, aluminum alloy profiles require aging treatment. Aging treatment refers to a heat treatment process where, after solution treatment, cold plastic deformation, casting, or forging, the alloy workpiece is placed at a high temperature or at room temperature to maintain its properties, shape, and dimensions over time.

[0003] Currently, large quantities of aluminum alloy profiles are usually framed and then fed into the aging furnace. However, batch feeding requires a high-load-bearing frame-shifting mechanism. But the space inside the aging furnace is limited, and the high-load-bearing frame-shifting mechanism is large in size, which not only affects the space inside the aging furnace, but also increases the overall cost of the aging furnace. Utility Model Content

[0004] The purpose of this invention is to provide a continuous aging furnace step-by-step frame moving device, which moves the material frames into the aging furnace one by one in a step-by-step manner, thereby solving the defects of the existing frame moving mechanism.

[0005] To solve the above-mentioned technical problems, this utility model provides a continuous aging furnace walking frame moving device, including fixed supports symmetrically arranged at the bottom of the continuous aging furnace for supporting the material frame;

[0006] Multiple stepping frame units are provided between the two sets of fixed supports, and the multiple stepping frame units are connected sequentially along the length direction;

[0007] The first stepping frame unit in the stepping direction is connected to a lifting piston cylinder and a stepping piston cylinder;

[0008] The lifting piston cylinder drives the stepping frame unit to rise or fall vertically;

[0009] The stepping piston cylinder drives the stepping frame moving unit and the raised material frame above to move horizontally.

[0010] Preferably, the stepping frame unit includes a support frame, a lifting frame, and a traveling roller assembly. The lifting frame is located inside the support frame and can be driven to rise, thereby lifting the material frame on the fixed support.

[0011] The traveling roller assembly is vertically arranged below the load-bearing frame to drive the load-bearing frame and its raised material frame to move horizontally.

[0012] Preferably, the load-bearing frame is provided in two sets, which are respectively arranged inside the two sets of fixed supports and extend parallel to the length direction of the fixed supports.

[0013] Preferably, the lifting frame is also provided in two sets, which are respectively arranged inside the two sets of the load-bearing frame and extend parallel to the length direction of the load-bearing frame.

[0014] Preferably, the traveling roller assembly includes a central support rod and rollers mounted at both ends of the central support rod, and the central support rod and the rollers at both ends are connected by an eccentric shaft.

[0015] Preferably, the lifting frame is connected to the eccentric shaft via a crank. When the lifting frame moves horizontally with the lifting piston cylinder, under the combined action of the eccentric shaft and the crank, the lifting frame performs a periodic upward and downward motion as the roller rotates.

[0016] Preferably, the load-bearing frames in the multiple stepping frame units are connected in sequence, so that the multiple load-bearing frames are synchronously pulled by the stepping piston cylinder; and the lifting frames are movably connected by tie rods, so that the multiple lifting frames are synchronously pulled by the lifting piston cylinder.

[0017] Preferably, there are two lifting piston cylinders, which are symmetrically installed on both sides of the traction plate, and the two lifting piston cylinders move synchronously, driving multiple stepping frame units to rise and fall synchronously.

[0018] Preferably, a linear guide rail is provided below the traction plate, the stepping piston cylinder is connected to the traction plate, and under the action of the stepping piston cylinder, the traction plate and the multiple stepping frame units move horizontally along the linear guide rail.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This continuous aging furnace walking frame moving device moves the material frames one by one into the aging furnace in a stepping manner. Specifically, the walking frame moving unit first lifts and then moves forward, then lowers and returns to the initial position, and repeats this cycle to achieve the stepping frame moving. In this way, the material frames can move forward one by one on the fixed support. Compared with batch frame moving by transmission, there is no need for lifting operations.

[0033] This utility model provides a walking beam frame moving device for a continuous aging furnace. Please refer to [link / reference]. Figures 1-3 The system includes fixed supports 1 symmetrically arranged at the bottom of the continuous aging furnace to support the material frame; multiple stepping frame units 2 are provided between the two sets of fixed supports 1, and the multiple stepping frame units 2 are connected in sequence along the length direction; the first stepping frame unit 2 in the stepping direction is connected to a lifting piston cylinder 3 and a stepping piston cylinder 4; the lifting piston cylinder 3 drives the stepping frame unit 2 to rise or fall in the vertical direction; the stepping piston cylinder 4 drives the stepping frame unit 2 and the material frame above it to move horizontally.

[0034] For details, please refer to Figures 4-6 The stepping frame unit 2 includes a support frame 201, a lifting frame 202, and a traveling roller assembly 203. The lifting frame 202 is disposed inside the support frame 201 and can be driven to rise, thereby lifting the material frame on the fixed support 1. The traveling roller assembly 203 is vertically arranged below the support frame 201 to drive the support frame 201 and the lifted material frame to move horizontally.

[0035] Furthermore, the load-bearing frame 201 is provided in two sets, respectively located inside the two sets of fixed supports 1, and extends parallel to the length direction of the fixed supports 1; the lifting frame 202 is also provided in two sets, respectively located inside the two sets of load-bearing frames 201, and extends parallel to the length direction of the load-bearing frame 201.

[0036] For further information, please refer to the following: Figure 7The traveling roller assembly 203 includes a central support rod 2031 and rollers 2032 mounted at both ends of the central support rod 2031. The central support rod 2031 and the rollers 2032 at both ends are connected by an eccentric shaft 2033. The lifting frame 202 is connected to the eccentric shaft 2033 by a crank 2034. When the lifting frame 202 moves horizontally with the lifting piston cylinder 3, under the combined action of the eccentric shaft 2033 and the crank 2034, the lifting frame 202 performs a periodic upward and downward motion as the rollers 2032 rotate.

Specifically, the walking frame moving unit first lifts (roller high position) and then moves forward, then lowers (roller low position) and returns to the initial position, and repeats this cycle to achieve the stepping frame moving. In this way, the material frames can move forward one by one on the fixed support. Compared with batch frame moving by transmission, there is no need for lifting operations, and the lifting device structure is more compact, occupies less space, and has a lower cost.
