Description

Technical Field

[0001] The utility model relates to the technical field of profile turning tooling, in particular to a device for profile turning operations. Background Art

[0002] Before L-shaped profiles are processed on the cutting platform, they need to be manually numbered on the front of the profiles on the ground, and the length, node positions, and specifications of the profiles to be cut are drawn. Then, a large number of profiles are hoisted onto the cutting platform for cutting using an electromagnetic crane. Figure 4 As shown, when a large number of profiles are placed on the cutting platform 10, some profiles 9 will be in a state with the reverse side 900 facing upward. Since the cutting mark is on the front side 901 of the profile, workers cannot cut according to the board surface information. At this time, tools are needed to flip the profile to a state with the front side 901 facing upward.

[0003] The traditional method uses a fixed wrench as a flipping tool, which requires two operators to stand on the two end faces of the profile, insert the opening of the wrench into the edge of the length direction of the profile respectively, and flip it in the counterclockwise direction by exerting force upward at the same time. Since the profile is a one-time, large-scale profile released onto the cutting platform 10 by an electromagnetic crane at the same time, the end faces of adjacent profiles may be uneven, and the two ends of the L-shaped profile may not be at the two ends of the platform, but one end is on the platform, and the other end is exposed more on one side of the platform. In this case, the operating space distance of the end on the platform is not enough, and it cannot be flipped directly by inserting the wrench. A crane is required to cooperate with the moving profile to adjust the end on the platform to a protruding state on one side of the cutting platform 10 before the flipping operation can be performed. Therefore, the use of traditional wrenches as flipping profiles is limited, and the operation is difficult. Two people are required to operate, and the wrench is prone to slipping out of the hand or rebounding during flipping. Utility Model Content

[0004] In view of the above problems, the utility model proposes a device for turning over profiles, which enables the profiles to be turned over to the front side conveniently and quickly while reducing safety risks.

[0005] To achieve the above purpose, the following technical scheme is adopted: a device for profile flipping operation, including a force arm body, a first support rod and a second support rod, and all three are square steel, the force arm body includes a square steel long arm and a square steel short arm, the square steel long arm serves as a hand-held end, and the square steel short arm serves as a support end for a workpiece, and there is an obtuse angle and an arc transition between the two, and reinforced ribs are welded; the center of the first support rod in the length direction is welded to the workpiece support surface of the square steel short arm, and the center of the second support rod in the length direction is welded to the end face of the square steel short arm, the first support rod and the second support rod are in a parallel state, and a clamping space for the workpiece is formed between the two.

[0006] Furthermore, the distance between two welding points of the square steel short arm and the first support rod and the second support rod is greater than half of the width of the profile.

[0007] Furthermore, the arc transition between the square steel long arm and the square steel short arm is 130°-140°.

[0008] Furthermore, the length of the long arm of the square steel is at least 5 times the length of the short arm of the square steel.

[0009] Furthermore, the lengths of the first support rod and the second support rod are 100 mm-150 mm.

[0010] Beneficial effects of the utility model: The first support rod and the second support rod of the utility model are respectively welded to the workpiece support end of the lever arm body to form a support space at the end of the profile. By clamping the end of the profile and using the handheld end of the lever arm body as a long lever arm to exert downward force, the profile can be flipped. Compared with the prior art,

[0011] 1. Flipping can be achieved by inserting one end of the profile, which is not restricted by the placement of adjacent profiles and does not require electromagnetic crane to move and adjust the position of the profile;

[0012] 2. The handheld force end and the clamping end form a large arc, which changes the direction of the flipping force from upward force to downward force, which is more conducive to the worker's force when flipping the profile;

[0013] 3. Compared with using a wrench to clamp and flip the profile at the edge, when clamping the profile at the end, the handheld end is long enough, and the profile will not fall out of the hand or rebound during the flipping process, which greatly reduces the safety risk.

[0019] The following is further described with reference to the accompanying drawings: Figure 1This is a schematic diagram of this example. As shown in the figure, a device for T-profile flipping operation includes a lever arm body 1, a first support rod 2 and a second support rod 3, and all three are square steel. The lever arm body 1 includes a square steel long arm 100 and a square steel short arm 101. The square steel long arm 100 serves as a hand-held end, and the square steel short arm 101 serves as a support end for a workpiece. There is a large arc transition between the two and a reinforcing rib 4 is welded. The center of the first support rod 2 in the length direction is welded to the workpiece support surface of the square steel short arm 101, and the center of the second support rod 3 in the length direction is welded to the end face of the square steel short arm 101. The first support rod 2 and the second support rod 3 are in parallel, and a clamping space for the workpiece is formed between the two.

[0020] The length of the processed L-shaped profile 9 on the market is about 8-15 meters, and the width is between 75-300mm. In this specific implementation, three square steels are used as the arm body 1, the first support rod 2 and the second support rod 3. The square steel long arm 100 of the arm body 1 is at least 5 times the square steel short arm 101. The longer the arm, the more labor-saving it is, ensuring that the profile can be pried manually. The end of the square steel short arm 101 is stamped by cold pressing equipment, so that the end of the square steel long arm 100 and the end of the square steel short arm 101 produce an arc of 130°-140°. In this example, the arc is stamped into 135°. The length of the selected first support rod 2 and the second support rod 3 is 100mm-150mm, ensuring sufficient insertion depth to ensure stability when clamping the end face of the profile. The first support rod 2 and the second support rod 3 are welded to the square steel short arm 101 respectively, and the distance between the two welding points is greater than half of the width of the profile 9. The larger the distance between the two, the larger the arm at the clamping point, and the more labor-saving it is. The reinforcing rib 4 is connected to the end of the square steel short arm 101 and the end of the square steel long arm 100 by welding, which plays a role in strengthening and stabilizing and preventing deformation during use.

[0021] When turning over the profile 9, Figure 2-3 As shown, on one side end face of the L-shaped profile 9, the second support rod 3 is placed below the profile 9, and the first support rod 2 is placed above the profile 9, and is pushed inward along the length direction of the profile 9 until the end of the profile 9 is completely fitted and close to the end of the square steel short arm 101, and the first support rod 2 and the second support rod 3 are respectively fitted with the upper and lower surfaces of the profile 9. At this time, the state is as shown in FIG. Figure 3 The worker holds the end of the square steel long arm 100, quickly presses the profile 9 downward to a certain angle, and then quickly pulls the profile 9 outward during the flipping process, and the profile 9 can complete the flipping operation by inertia.
