Description
Technical Field

[0002] In manufacturing, nuts are widely used components for connecting and fastening various mechanical structures. The production quality and efficiency of nuts are of great significance to the entire industrial production process. With the acceleration of industrialization, the demand for nuts is constantly increasing, and the requirements for their quality and precision are also becoming more and more stringent. As a metal processing machine, the punch press plays an important role in nut production. With the advancement of technology and the development of manufacturing processes, modern industry has placed higher demands on punch presses used in nut production.
[0003] In traditional nut manufacturing processes, machining the nut and rounding the machined area are two completely separate processes. After the initial machining of the nut is completed, it needs to be transferred to a special rounding equipment or process. This not only increases the complexity of the production process but also leads to an extension of production time. Due to the additional process and equipment requirements, labor costs and equipment investment increase significantly. This distributed processing method means that each process requires separate time and resource investment, making it impossible to complete the processing in one go, which seriously restricts the production efficiency of nuts. Therefore, a punch press for nut production is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Please refer to Figure 1 - Figure 2 This utility model provides an embodiment of a punch press for nut production, including a worktable 1, which serves to stabilize the bottom of the device. A mounting block 2 is fixedly connected to the front of the worktable 1. The mounting block 2 is a metal box with a rectangular groove on the top. A mounting frame 3 is fixedly connected to the top of the worktable 1. The mounting frame 3 is an arc-shaped support frame. A functional box 4 is fixedly connected to the front of the mounting frame 3. The functional box 4 is equipped with a pull rod 5. A cylinder 6 is installed on the top of the functional box 4. The functional box 4, pull rod 5 and cylinder 6 are all prior art, so they will not be described in detail below. A rounding mechanism 7 is provided at the bottom of the functional box 4. A clamping mechanism 8 is provided inside the mounting block 2.
[0025] Please refer to Figure 1 - Figure 3The rounding mechanism 7 consists of a drive assembly and a rounding assembly. The rounding assembly includes a telescopic rod 704, which connects to the mounting plate 702 and the pressing plate 705. The bottom of the telescopic rod 704 is fixedly connected to the pressing plate 705. The telescopic rod 704 drives the pressing plate 705 to press against the surface of the nut to be processed. A rounding block 706 is installed on the inner side of the pressing plate 705. A grinding strip is provided at the bottom of the rounding block 706 for rounding work. The top of the telescopic rod 704 is fixedly connected to the bottom of the mounting plate 702.
[0026] Please refer to Figure 1 - Figure 3 The drive assembly includes a hydraulic rod 701. By pulling the pull rod 5, the cylinder 6 drives the hydraulic rod 701 to move downward. The surface of the hydraulic rod 701 is rotatably connected to the mounting plate 702. The downward movement of the hydraulic rod 701 drives the mounting plate 702 to move downward. The bottom of the hydraulic rod 701 is fixedly connected to the opening head 703. The mounting plate 702 drives the opening head 703 and the telescopic rod 704 to move downward. The surface of the opening head 703 is fixedly connected to the inner wall of the rounding block 706 through the connecting rod. This enables the rounding of the nut processing area during the nut processing process, reducing the complexity of the production process and eliminating the need for additional processes and equipment to round the nut processing area.
[0027] Please refer to Figure 4 - Figure 5 The clamping mechanism 8 includes a motor 801, with a rotating rod 802 fixedly connected to the output end of the motor 801. When the motor 801 is started, it drives the rotating rod 802 to rotate. The rotating rod 802 has a threaded groove on its surface and a movable block 803 on its surface. The rotating rod 802 drives the movable block 803 to move relative to it. The motor 801 is fixedly connected to the left side of the mounting block 2, and the surface of the rotating rod 802 is rotatably connected to the inner wall of the mounting block 2. The clamping mechanism 8 also includes a fixed rod 804. The movable block 803 drives the fixed rod 804 to move. A clamping frame 805 is fixedly connected to the top of the fixed rod 804, and the fixed rod 804 drives the clamping frame 805 to move relative to it. A fixed block 806 is elastically slidably connected to the inner wall of the clamping frame 805. A pressing plate 807 is rotatably connected to the inner left side of 806, causing the clamping frame 805 to drive the fixing block 806 to clamp the nut to be processed. While in contact with the nut, the pressing plate 807 on its inner wall rotates. The bottom of the fixing rod 804 is fixedly connected to the top of the moving block 803, so that the pressing plate 807 tilts down to press the top of the nut. The inner wall of the fixing rod 804 is slidably connected to the inner wall of the top of the mounting block 2. The bottom of the clamping frame 805 is in contact with the top of the mounting block 2. This allows for the simultaneous pressing of the top of the nut while clamping nuts of different sizes during nut processing, preventing the nut from shifting or tilting during punching, thereby increasing the rework rate, reducing the number of scraps caused by punching deviation, and saving materials and production costs.
[0028] Working Principle: During operation, the operator places the nut to be processed on the top surface of the mounting block 2 at the front of the workbench 1. Then, the motor 801 is started, driving the rotating rod 802 to rotate. The rotating rod 802 causes the moving block 803 on its surface to move relative to the nut. The moving block 803 causes the fixed rod 804 to move, which in turn causes the clamping frame 805 to move relative to the nut. This causes the clamping frame 805 to clamp the fixed block 806, and simultaneously, the inner wall pressing plate 807 rotates, causing the pressing plate 807 to tilt and press down on the top of the nut. This allows for clamping nuts of different sizes while simultaneously pressing the top of the nut during processing, preventing the nut from shifting or tilting during punching, thus reducing rework rate and minimizing the impact of punching defects. The reduced number of defective products due to hole deviation saves materials and production costs. After the nut is fixed, the operator pulls the lever 5, which in turn moves the cylinder 6 to lower the hydraulic rod 701. The lowering of the hydraulic rod 701 moves the mounting plate 702, which in turn moves the punch head 703 and the telescopic rod 704. The lowering of the telescopic rod 704 moves the pressing plate 705, bringing it into contact with the nut surface. Then, the punch head 703 continues to descend to punch the nut hole and moves the rounding block 706 on its surface to further round the nut. This allows for rounding of the nut's machining area during the nut machining process, reducing complex production processes. No additional steps or equipment are needed to round the nut's machining area, completing the machining in one go, saving time and labor costs, and greatly improving the nut production efficiency.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
