Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold drawing forming technology of steel profiles, specifically to a traction device for cold drawing forming of steel profiles. Background Technology
[0002] Cold drawing machines apply pressure to metal materials through molds, causing them to undergo plastic deformation, thereby achieving precise dimensional control. The shape and size of the mold directly determine the final form of the processed metal material, such as round, square, or rectangular. The mold can also improve the surface finish and mechanical properties of the material, such as strength and hardness.
[0003] Existing cold drawing machines require manual application of lubricating oil to the steel surface using a brush during the drawing process. This requires operators to stay near the equipment for extended periods, resulting in a waste of human resources. Furthermore, when using a drawing clamp structure to draw hollow steel sections, one end of the hollow steel section is typically squeezed and deformed to increase the friction surface and thus increase friction for drawing the steel. However, the deformed area is difficult to repair or needs to be removed later, leading to some waste. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing cold drawing machines require constant manual lubrication of the steel profiles, which wastes human resources. Furthermore, the clamping clamps cause severe deformation at one end of the steel profile, necessitating its removal later and resulting in waste.
[0005] To solve the above problems, the technical solution adopted by this utility model is a cold-drawing forming traction device for steel profiles, including: an equipment frame, a pair of positioning frames fixed on the upper side of the equipment frame, a cold-drawing template inserted in the middle of the positioning frames, a chain transmission mechanism and a jaw structure inside the equipment frame, the jaw structure including a sliding plate and clamping clamps, support rods fixed on both sides of the positioning frames on the upper side of the equipment frame, support plates fixed at the top of the support rods, an arc-shaped tube fixed in the middle below the two support plates, a connecting pipe connected to the top of the arc-shaped tube, a pump fixed below the equipment frame, the output end of the pump connected to the connecting pipe, an oil groove opened between the pair of positioning frames on the upper side of the equipment frame, the input end of the pump connected to the oil groove, slots opened on opposite sides of the clamping clamps, and a positioning clamp placed above the sliding plate.
[0006] As a further embodiment of this utility model: the positioning clamp includes a support column, and the top of the support column is rotatably provided with a clamp body one and a clamp body two that are hinged to each other. One end of the clamp body one and the clamp body two is fixed with a pressure handle. Pressing the pressure handle can cause the clamp body one and the clamp body two to expand outward, thereby cooperating with the clamping pliers to clamp the steel. One side of the clamp body one and the clamp body two is fixed with an anti-slip protrusion.
[0007] As a further embodiment of this utility model: a die opening is provided in the middle of the cold drawing template, a clamping module is inserted on the opposite side of the clamping clamp, and a positioning clamp is located in the middle of the die opening and the clamping module. The positioning clamp and the clamping module cooperate to facilitate clamping of the steel profile.
[0008] As a further embodiment of this invention, several drip holes are provided on the lower side of the arc-shaped tube to facilitate the dripping of lubricating oil.
[0009] As a further embodiment of this utility model: a control cabinet is provided on one side of the equipment frame, and both the pump and the control cabinet are electrically connected to an external power source.
[0010] Compared with the prior art, the advantages of this utility model are as follows: This application adds an arc-shaped tube, an oil tank, and a pump. The pump delivers the lubricating oil in the oil tank into the arc-shaped tube, and the lubricating oil drips evenly onto the surface of the steel section through the drip holes on it for lubrication. A positioning clamp structure is added, which can extend into the inside of the steel section for support when the hollow steel section is pulled, thereby cooperating with the clamping pliers to clamp the hollow steel section, which can reduce the deformation of the hollow steel section and thus reduce the waste of steel section.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.
[0020] Combined with appendix Figure 1 , 3 It can be seen that the equipment includes a frame 1, a pair of positioning frames 2 are fixed on the upper side of the frame 1, a cold-drawn template 3 is inserted in the middle of the positioning frame 2, and a die opening 3.1 is opened in the middle of the cold-drawn template 3. A clamping module 5.2 is inserted on the opposite side of the clamping clamp 5. The positioning clamp 10 is located in the middle of the die opening 3.1 and the clamping module 5.2. The positioning clamp 10 and the clamping module 5.2 cooperate to facilitate the clamping of the steel. The equipment frame 1 is equipped with a chain drive mechanism and a jaw structure. The jaw structure includes a sliding plate 4 and clamping clamps 5. Support rods 6 are fixed on both sides of the positioning frame 2 on the upper side of the equipment frame 1. Support plates 7 are fixed at the top of the support rods 6. Arc-shaped tubes 7 are fixed in the middle of the lower part of the two support plates 7. Several drip holes are opened on the lower side of the arc-shaped tubes 7 to facilitate the dripping of lubricating oil. A connecting pipe 8 is connected to the top of the arc-shaped tubes 7. A pump 9 is fixed below the equipment frame 1. The output end of the pump 9 is connected to the connecting pipe 8. An oil tank 1.1 is opened on the upper side of the equipment frame 1 between the pair of positioning frames 2. The input end of the pump 9 is connected to the oil tank 1.1.
[0021] Combined with appendix Figure 2 , 4 It can be seen that the clamping pliers 5 have slots 5.1 on opposite sides. A positioning clamp 10 is placed above the sliding plate 4. The positioning clamp 10 includes a support column 10.1. The top of the support column 10.1 is rotatably provided with a clamp body 10.2 and a clamp body 10.3 that are hinged to each other. A pressure handle 10.4 is fixed at one end of the clamp body 10.2 and the clamp body 10.3. Pressing the pressure handle 10.4 can cause the clamp body 10.2 and the clamp body 10.3 to expand outward, thereby cooperating with the clamping pliers 5 to clamp the steel. An anti-slip protrusion 10.5 is fixed on one side of the clamp body 10.2 and the clamp body 10.3.
[0022] The working principle of this application is as follows: When drawing hollow steel, one end of the hollow steel is first inserted into the die 3.1 and extends out from one end of the cold drawing template 3. Then, the clamping clamp 5 is moved to the side of the cold drawing template 3, and the positioning clamp 10 is placed on the upper side of the sliding plate 4 so that the clamp body 10.2 and clamp body 20.3 can extend into the inside of the hollow steel. When the clamping clamp 5 clamps, it will squeeze the pressure handle 10.4 to make the clamp body 10.2 and clamp body 20.3 expand outward so as to cooperate with the clamping module 5.2 to clamp the hollow steel. Then, the chain drive mechanism can be started to pull the jaw mechanism for drawing. When drawing the steel, lubricating oil is filled into the oil tank 1.1 and the pump 9 is started to pump to the arc tube 7 to lubricate the surface of the steel so as to facilitate smooth drawing.
