Description

Technical Field

[0001] The invention belongs to the technical field of leisure chair processing equipment, in particular to a leisure chair steel pipe angle bending equipment. Background Art

[0002] A leisure chair is a piece of furniture designed to provide a comfortable sitting or lying experience. It is usually placed in homes, offices, public places and other environments for people to rest, relax or engage in light activities. Choose a suitable leisure chair according to the occasion and needs. For example, you can choose a rocking chair or a folding lounge chair on the balcony, and an electric functional chair or a comfortable sofa chair in the office.

[0003] During the production and processing of leisure chairs, the brackets need to bend the steel pipes to different degrees in order to meet different production needs. However, the bending range of traditional processing equipment is relatively limited, and the residual stress of the steel pipes after bending cannot be well released, which is not conducive to subsequent production and processing. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides an angle bending device for steel pipes for leisure chairs, which solves the problem that the bending range of traditional processing equipment is relatively limited and the residual stress of the steel pipe cannot be well released after bending, which is not conducive to subsequent production and processing.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a leisure chair steel pipe angle bending equipment, including a mounting frame, a brake cylinder, a support frame, a negative pressure arc plate and a servo motor, the brake cylinder is fixedly connected to the inner top of the mounting frame, the driving end of the brake cylinder is fixedly connected to a limit frame, an adjusting screw is arranged inside the limit frame, the outer wall of the limit frame is fixedly connected to a servo motor, the driving end of the servo motor penetrates the side wall of the limit frame and extends to the inside thereof and is fixedly connected to one end of the adjusting screw, the outer surface thread of the adjusting screw is divided into two sections with opposite thread directions and equal lengths, the outer surface thread sleeve of the adjusting screw is provided with two adjusting seats, the positions of the two adjusting seats are symmetrically distributed about the middle position of the adjusting screw, the bottoms of the two adjusting seats are fixedly connected with connecting short shafts, the ends of the two connecting short shafts away from the adjusting seats penetrate the limit frame and extend to the bottom thereof and are fixedly connected to the two ends of the negative pressure arc plate, the bottom of the limit frame is fixedly connected with a support rod, and the end of the support rod away from the limit frame is fixedly connected to the top of the negative pressure arc plate.

[0006] Preferably, the mounting bracket is fixedly arranged on the top of the supporting bracket, and two fixing brackets are fixedly arranged on the top of the supporting bracket, and support shafts are rotatably arranged inside the two fixing brackets.

[0007] Preferably, a U-shaped limiting guide groove is provided at the bottom of the limiting frame, and the connecting short shaft is slidably engaged in the U-shaped limiting guide groove.

[0008] Working principle: When in use, the steel pipe to be processed is placed above the fixed frame. When the steel pipe is bent into different angles as needed, the servo motor is started, and the driving end of the servo motor drives the adjusting screw to rotate. Since the thread on the outer surface of the adjusting screw is divided into two sections with opposite thread directions and equal lengths, when the adjusting screw rotates, the distance between the two adjusting seats arranged on the outer surfaces of the two sections of the thread on its outer surface will change. By adjusting the distance between the two adjusting seats and cooperating with the support rod, the bending degree of the negative pressure arc plate can be changed, thereby obtaining different processing negative pressures to achieve processing requirements of different bending degrees. During the processing, since a long-sized negative pressure arc plate is used for force processing, the negative pressure arc plate will be kept in contact with the steel pipe to be processed during the processing, so that the stress at the bending part of the steel pipe will be released, which is more conducive to subsequent processing. During the pressure application process of the negative pressure arc plate, since the support shaft is rotatably connected to the fixed frame, when the steel pipe is bent, the relative movement between the material itself and the support shaft will be smoother, which is more conducive to processing.

[0009] (III) Beneficial effects The present invention provides a leisure chair steel pipe angle bending device, which has the following beneficial effects: 1. The leisure chair steel pipe angle bending equipment, when the adjusting screw rod rotates, the distance between the two adjustment seats arranged on the outer surfaces of the two sections of the threads on its outer surface will change. By adjusting the distance between the two adjustment seats and cooperating with the support rod, the bending degree of the negative pressure arc plate can be changed, thereby obtaining different processing negative pressures to achieve processing requirements with different bending degrees.

[0010] 2. During the processing, the leisure chair steel pipe angle bending equipment will keep the negative pressure arc plate in close contact with the steel pipe to be processed, so that the stress at the bending part of the steel pipe will be released, which is more conducive to subsequent processing.

[0011] 3. During the pressure application process of the negative pressure arc plate, since the support shaft is rotationally connected to the fixed frame, when the steel pipe is bent, the relative movement between the material itself and the support shaft will be smoother, which is more conducive to the processing.
