Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe stretching equipment, specifically a safety protection device for stainless steel coil stretching equipment. Background Technology

[0002] The drawing machine is a key piece of equipment for the precision processing of metal tubes and wires. It mainly achieves material diameter reduction, wall thickness control, and performance optimization through continuous drawing process. Its working principle is that metal billets (such as copper tubes, aluminum tubes, steel tubes, etc.) are fed in by a wire feeding device and pass through multiple sets of drawing dies of different specifications in sequence. Under the action of traction force, they undergo plastic deformation and gradually reach the target size. At the same time, the drawn material is continuously wound up by a take-up reel, forming a closed-loop production process. The drawing machine has the characteristics of continuous production, high efficiency, and high material utilization rate. It is widely used in air conditioning and refrigeration, automotive piping, electronic communications and other fields, and is the core equipment for manufacturing precision metal tubes.

[0003] Transmission stainless steel coil stretching equipment often uses a cylinder to push a pressure roller to squeeze the stainless steel tube on the outside of the disc. This structure often requires a cylinder with a large thrust to achieve the clamping effect. After long-term use, the problem of insufficient pressure failing to suppress the stress rebound of the tube may occur. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a safety protection device for stainless steel coil stretching equipment, thereby solving the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety protection device for a stainless steel coil stretching equipment, comprising a coil stretching machine main frame, a drive unit and a coil, wherein a jaw assembly is provided in the recess inside the coil, a stretching die assembly is also provided on the front side of the coil stretching machine main frame, and protective components are provided on both sides inside the coil stretching machine main frame. The protective assembly includes a first fixed base and a second fixed base. A first rotating shaft is provided on the outer side of the first fixed base. A clamping rod is rotatably mounted on the outer side of the first fixed base via the first rotating shaft. A bracket is fixedly mounted on the side of the clamping rod facing the disc cylinder away from the first rotating shaft. A pressure roller is rotatably mounted on the inner side of the bracket. A fixed plate is fixedly mounted on the outer side of the second fixed base. An ear seat is fixedly mounted on the outer side of the fixed plate away from the second fixed base. A second rotating shaft is rotatably mounted on the inner side of the ear seat. A push rod cylinder is fixedly mounted on the outer side of the second rotating shaft. A connecting rod is fixedly mounted on the movable end of the push rod cylinder. An inner groove is provided on the inner side of the clamping rod. A guide strip is fixedly mounted inside the inner groove. A slide is slidably mounted inside the inner groove. A third rotating shaft is provided between the slide and the connecting rod.

[0006] Preferably, the main frame of the coiling machine includes a top plate, a first leg, a second leg, and a reinforcing plate. The lower part of the top plate is provided with two identical first legs and second legs. A reinforcing plate is provided between the first legs and the second legs. The first fixed seat is fixedly connected to the first leg, and the second fixed seat is fixedly connected to the second leg.

[0007] Through the above technical solution, the first and second legs provide a reliable support foundation for the protection components, while the reinforcing plate further enhances the overall structural strength and stability of the main frame, ensuring that the protection components will not shift or shake due to force during operation.

[0008] Preferably, two identical protective components are provided, and the two protective components are diagonally distributed about the center line of the disc.

[0009] Through the above technical solution, the two diagonally distributed protective components can provide symmetrical protection for the stainless steel coil during the stretching process from both sides of the cylinder, ensuring that the coil remains in a stable protective state during the stretching process and effectively reducing the risk of safety accidents caused by force imbalance.

[0010] Preferably, the push rod cylinder is located between the ear seat and the slide seat, the push rod cylinder is rotatably connected to the ear seat via the second rotating shaft, and the connecting rod is rotatably connected to the slide seat via the third rotating shaft.

[0011] Preferably, there are two identical guide bars, which are symmetrically distributed on the outside of the slide block, and the guide bars are slidably connected to the slide block.

[0012] Through the above technical solution, during the use of the protective components, the push rod cylinder pushes the clamping rod to rotate around the rotating shaft through the connecting rod and the slide. During the process of the push rod cylinder pushing the connecting rod and the slide, the slide slides under the guidance of the guide bar. At the same time, the distance between the pressure roller and the disc decreases, and the spirally wound stainless steel tube is clamped to prevent the stainless steel tube from being broken by stress during spiral winding, thus playing a protective role.

[0013] Compared with the prior art, this utility model provides a safety protection device for stainless steel coil stretching equipment, which has the following beneficial effects: This safety protection device for stainless steel coil stretching equipment uses a push rod cylinder, connecting rod, and slide block to drive the clamping rod to rotate, reducing the distance between the pressure roller and the coil. This effectively clamps the spirally wound stainless steel tube, preventing it from bursting due to stress during the winding process and providing safety protection. The protection component only requires a short cylinder to clamp the stainless steel tube on the outside of the coil, making it more practical. Furthermore, two diagonally distributed protection components provide symmetrical protection from both sides of the coil, ensuring that the stainless steel coil remains in a stable protective state during the stretching process. By balancing the force, the device effectively reduces the risk of safety accidents caused by imbalance. Attached Figure Description

[0018] Example 2: like Figure 2-8 As shown, as an improvement to the previous embodiment, in order to keep the coil in a stable protective state during the stretching process.

[0019] Specifically, the protection component 6 includes a first fixing seat 601 and a second fixing seat 604. A first rotating shaft 602 is provided on the outer side of the first fixing seat 601. A clamping rod 603 is rotatably mounted on the outer side of the first fixing seat 601 via the first rotating shaft 602.

A pressure roller 615 is rotatably mounted on the inner side of the bracket 614. A fixing plate 605 is fixedly mounted on the outer side of the second fixing seat 604. The fixing plate 605 is located away from the second fixing seat 604. 04. An ear seat 606 is fixedly installed on the outer side of one end. A rotating shaft 607 is rotatably installed on the inner side of the ear seat 606. A push rod cylinder 608 is fixedly installed on the outer side of the rotating shaft 607.

During the process of the push rod cylinder 608 pushing the connecting rod 609 and the slide 611, the slide 611 slides under the guidance of the guide bar 613. At the same time, the distance between the pressure roller 615 and the disc 3 decreases, and the spirally wound stainless steel tube is clamped to prevent the stainless steel tube from being broken by stress during spiral winding, thus playing a protective role.
