[0002] Spring steel is a special alloy steel used to manufacture various springs and other elastic components. Based on performance requirements and application conditions, it can be divided into ordinary alloy spring steel and special alloy spring steel. Spring steel possesses excellent comprehensive properties, including superior metallurgical quality, good surface finish, and precise shape and dimensions.
[0003] Currently, we generally cut the spring steel we receive directly without correcting its curvature. This results in many spring steel sections still having curvature being processed directly, leading to some finished materials failing to meet requirements. While various types of spring steel cutting equipment exist, there is a lack of pre-processing for straightening the curvature of the spring steel. This issue is a problem that urgently needs to be addressed by those in the field. Utility Model Content

[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0022] Please see Figure 1-5 The present invention provides a technical solution: a spring steel cutting device, including a horizontal band saw 1, a straightening component and a clamping component. The horizontal band saw 1 is provided with a worktable 9, and a worktable 8 is fixedly connected to the rear of the worktable 9. The straightening component is provided on the upper surface of the worktable 8 for straightening the curvature of the spring steel. The clamping component is fixed above the worktable 9 for clamping the straightened spring steel.
[0023] Two sets of supports 7 are provided on the upper surface of the workbench 28. The two sets of supports 7 are symmetrically distributed on the upper surface of the workbench 28 and are used to place the spring steel that needs to be straightened.
[0024] The straightening components are divided into left and right groups. Each group of straightening components includes a linear motor 2, a drag chain fixing plate 3, a cylinder 4, a roller 5, and a bracket 6. Each group of straightening components is symmetrically distributed on the upper surface of the workbench 2 8. The linear motor 2 is fixedly connected to the upper surface of the workbench 2 8. The drag chain fixing plate 3 is slidably connected to the linear motor 2 to achieve sliding straightening of the roller 5. The cylinder 4 is fixedly connected to the upper part of the drag chain fixing plate 3. The output end of the cylinder 4 is fixedly connected to one side of the bracket 6. The roller 5 is installed inside the bracket 6. When straightening the spring steel, the cylinder 4 is started, which pushes the bracket 6 forward with the output end, so that the roller 5 applies pressure inward to the spring steel to straighten the curvature. The linear motor 2 is started, which makes the drag chain fixing plate 3 slide along a straight line, while driving the roller 5 to straighten the curvature of the left and right sides of the spring steel along a straight line, thus improving the straightening efficiency.
[0025] The clamping components include a bed 10, a handwheel 11, a lead screw 12, and two vises 13. The bed 10 is fixed above the worktable 9. The lead screw 12 is fixedly connected inside the bed 10. A hydraulic clamping cylinder 14 is provided on the left side of the bed 10. The hydraulic clamping cylinder 14 has an inner hole. The left end of the lead screw 12 passes through the inner hole of the hydraulic clamping cylinder 14 and is fixedly connected. The left end of the lead screw 12 is fixedly connected to the handwheel 11 (e.g., ...). Figure 5 As shown, the right vise 13 is fixedly connected to the bed 10, and the left vise 13 is slidably connected to the lead screw 12 to clamp the straightened spring steel. The spring steel is placed on the bed 10 with the right surface of the right vise 13 against it. The worker rotates the handwheel 11, which causes the left vise 13 to move to the right under the drive of the lead screw 12, thereby pressing against and clamping the spring steel.
[0026] A feed plate 15 is provided at the front of the bed 10 to place the cut spring steel and some of the iron filings generated during cutting.
[0027] The horizontal band saw 1 is equipped with a control panel 16 on the top. The control panel 16 is electrically connected to the linear motor 2 and the cylinder 4 to drive the linear motor 2 and the cylinder 4.
[0028] The surface of roller 5 that contacts the spring steel is arc-shaped, which makes it easier for roller 5 to better fit the spring steel and apply straightening force inward.
[0029] Working principle: First, the spring steel needs to be straightened. The worker places both ends of the spring steel on the support 7 and uses the straightening component to correct its curvature. The worker uses the control panel 16 to start the cylinder 4, so that the rollers 5 on the left and right sides are in contact with the surface of the spring steel and apply force inward. Then, the linear motor 2 is started, so that the rollers 5 can move in a straight line under the drive of the drag chain fixing plate 3, and the surface of the spring steel is straightened. In this way, the curvature of the spring steel surface can meet the actual requirements before the spring steel is cut, reducing the defect rate.
[0030] Secondly, after the straightening is completed, the worker pushes the spring steel forward to the bed 10. The spring steel is placed on the bed 10 with the right vise 13 against it. Then, the handwheel 11 is turned so that the left vise 13 slides to the right under the drive of the screw 12 until the left vise 13 presses against the spring steel. The worker then presses the clamping or loosening button on the control panel 16 to clamp or loosen the spring steel.
[0031] Finally, the clamped spring steel is cut.
