Description

Technical Field

[0001] This utility model belongs to the field of mold positioning and relates to a mold positioning structure for punch presses. Background Technology

[0002] In modern industrial production, the punch press is a key piece of equipment for forming metal sheets. The performance of its mold positioning structure directly affects the quality of stamped parts, production efficiency, and mold life. As the manufacturing industry transforms towards a multi-variety, small-batch, and flexible production model, higher requirements are placed on the flexibility, versatility, and adaptability of the mold positioning structure. There is an urgent need for a positioning technology that can quickly adapt to different workpiece specifications to meet diverse production needs.

[0003] Currently, the positioning structure of punch press dies mainly adopts fixed positioning methods, such as positioning the die and the punch press table by cooperating with positioning pins and positioning holes, or setting fixed blocks and positioning plates on the die to limit the workpiece. The technical principle of this type of positioning structure is to form a fixed positioning reference through the precise machining and assembly of mechanical parts, so as to ensure the positional accuracy of the die during the stamping process. In addition, some high-precision dies also use the cooperation of guide pillars and guide sleeves to achieve precise guidance of the upper and lower dies through sliding or rolling contact. These traditional structures can ensure high positioning accuracy and stability in the mass production of a single product.

[0004] However, the existing fixed positioning structure is difficult to adapt to the production mode of multiple varieties and small batches. When it is necessary to produce workpieces of different specifications, it is often necessary to replace the entire set of molds or reprocess and modify the molds. Not only is the mold replacement time long and the downtime cost increased, but frequent mold replacement also leads to high mold development and maintenance costs, which seriously restricts the improvement of production efficiency and the control of production costs. Utility Model Content

[0005] The purpose of this utility model is to provide a die positioning structure for punch presses, which aims to solve the problem that the existing fixed positioning structure is difficult to adapt to the frequent die changes in multi-variety, small-batch production, resulting in low efficiency and high cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A die positioning structure for a punch press includes a punch press body, a die slidably connected to the top of the punch press body, and a plurality of positioning components disposed on the top of the punch press body;

[0008] Each of the aforementioned positioning components includes a connecting rod. The bottom of the connecting rod is fixedly connected to the upper surface of the punch press body. A screw is threaded inside the connecting rod, and a slider is slidably connected inside the connecting rod. One end of the screw is rotatably connected inside the slider. A support plate is fixedly connected to the upper surface of the slider. A spring is provided on one side of the support plate. One end of the spring is fixedly connected to the side wall of the support plate, and the other end is fixedly connected to a clamping block. The clamping block fits against the outer wall of the mold. An installation component is provided on one side of the connecting rod.

[0009] As a further description of the above technical solution:

[0010] The mounting assembly includes a connecting shaft and a sliding column. One side of the connecting shaft is fixedly connected to the side wall of the connecting rod, and the sliding column is slidably connected inside the connecting shaft.

[0011] As a further description of the above technical solution:

[0012] The punch press body has a slot inside, and two symmetrical springs are installed inside the punch press body.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the inner wall of the slot, and the other end is fixedly connected to a rubber ring.

[0015] As a further description of the above technical solution:

[0016] A locking post is fixedly connected to the outer wall of the sliding post. The locking post engages with the locking groove, and the outer wall of the locking post contacts the upper surface of the rubber ring.

[0017] As a further description of the above technical solution:

[0018] A knob is fixedly connected to the top of the sliding column, and an extrusion disc is fixedly connected to the outer wall of the sliding column. The extrusion disc slides inside the connecting shaft.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the sliding column is provided with a spring three. One end of the spring three is fixedly connected to the inner wall of the connecting shaft, and the other end is fixedly connected to the side wall of the extrusion plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by rotating the screw, the slider is pushed to slide inside the connecting rod. The sliding of the connecting rod further drives the clamping block to contact the outer wall of the mold, compressing the spring and causing the spring to undergo elastic deformation. This achieves the effect of positioning according to different mold sizes, solving the problem of time-consuming and labor-intensive frequent mold changes in multi-variety production, and improving production efficiency and mold versatility.

[0023] 2. In this utility model, by inserting the sliding post into the slot and then rotating the knob to make the sliding post drive the locking post to rotate synchronously inside the slot, the positioning component can be quickly installed and disassembled, which solves the problem of cumbersome disassembly of the fixed positioning structure and improves the flexibility of the structure.

[0030] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the die positioning structure for a punch press proposed by this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0031] Reference Figures 1-3The present invention provides an embodiment of a die positioning structure for a punch press, comprising a punch press body 1, a die 2 slidably connected to the top of the punch press body 1, and a plurality of positioning components provided on the top of the punch press body 1 for positioning the die 2 to ensure the stability and accuracy of the die 2 during the punching process.

[0032] Multiple positioning components include connecting rods 3. The bottom of the connecting rods 3 is fixedly connected to the upper surface of the punch press body 1 to ensure that the positioning components can be stably held in the designated position. A screw 4 is threaded inside the connecting rod 3, and a slider 5 is slidably connected inside the connecting rod 3. One end of the screw 4 is rotatably connected inside the slider 5. A support plate 6 is fixedly connected to the upper surface of the slider 5. A spring 7 is provided on one side of the support plate 6 to adjust the strength of the positioning force, ensuring that the clamping block 8 can stably and tightly fit against the outer wall of the mold 2. Under the action of the spring 7, the clamping block 8 can adapt to different shapes of molds 2 and make close contact with the outer wall of the mold 2, thereby achieving effective clamping of the mold 2. One end of the spring 7 is fixedly connected to the side wall of the support plate 6, and the other end is fixedly connected to the clamping block 8, which fits against the outer wall of the mold 2. An installation component is provided on one side of the connecting rod 3 to realize the adjustment and disassembly functions of the positioning components, so as to facilitate the adjustment of the clamping position of the mold 2 as needed.

[0033] Specifically, when the punch press needs to accommodate workpieces of different specifications, molds 2, or to produce multiple varieties, firstly, the operator carefully places the mold 2 on the surface of the punch press body 1, ensuring the initial position of the mold 2 is correct. Next, by rotating the screw 4, the operator drives the screw 4 to rotate, causing the screw 4 to engage with the internal thread of the connecting rod 3, thereby pushing the slider 5 to slide within the connecting rod 3. As the slider 5 moves, the clamping block 8 gradually moves closer to the outer wall of the mold 2. The contact between the clamping block 8 and the outer wall of the mold 2 applies pressure, causing the spring 7 to be compressed. The spring 7 begins to undergo elastic deformation and stores elastic potential energy. Through this process, the clamping force of the clamping block 8 on the mold 2 can be adjusted according to the different sizes of the mold 2, ensuring the stability and reliability of the mold 2 on the punch press.

[0034] Reference Figure 4 and Figure 5The mounting assembly includes a connecting shaft 9 and a sliding column 10. One side of the connecting shaft 9 is fixedly connected to the side wall of the connecting rod 3. The sliding column 10 is slidably connected inside the connecting shaft 9, allowing it to move linearly along the direction of the connecting shaft 9. A slot 11 is provided inside the punch press body 1, located at an appropriate position within the punch press body 1 to facilitate cooperation with other components. Symmetrical springs 12 are installed inside the punch press body 1. One end of each spring 12 is fixedly connected to the inner wall of the slot 11, and the other end is fixedly connected to a rubber ring 13. The rubber ring 13 provides a cushioning effect, effectively reducing... To reduce vibration and friction during movement, and increase the friction of the locking column 16, the locking column 16 is fixedly connected to the outer wall of the sliding column 10. The locking column 16 engages with the locking groove 11. The outer wall of the locking column 16 contacts the upper surface of the rubber ring 13, further enhancing the stability of the structure and providing additional support for the sliding column 10. A knob 17 is fixedly connected to the top of the sliding column 10. An extrusion plate 14 is fixedly connected to the outer wall of the sliding column 10. The extrusion plate 14 slides inside the connecting shaft 9. A spring 15 is provided on the outer wall of the sliding column 10. One end of the spring 15 is fixedly connected to the inner wall of the connecting shaft 9, and the other end is fixedly connected to the side wall of the extrusion plate 14.

[0035] Specifically, when the positioning assembly needs to be disassembled or reassembled, the user first inserts the sliding column 10 into the slot 11 inside the punch press body 1. The inner wall of the slot 11 fits tightly with the outer wall of the engaging column 16, ensuring that the sliding column 10 can be stably inserted and slide inside it. After the sliding column 10 enters the slot 11, the engaging column 16 will be tightly engaged in the predetermined position of the slot 11 by the elastic force of the second spring 12. At this time, one end of the second spring 12 is fixedly connected to the inner wall of the slot 11, and the other end is connected to the rubber ring 13. By compressing the second spring 12, an upward counterforce is provided to the sliding column 10, ensuring that the engaging column 16 can be firmly fixed in the correct position. The user then rotates the knob 17 to drive the engaging column 16 to rotate synchronously. The rotation of the engaging column 16 inside the slot 11 makes the two engage, further simplifying the disassembly and assembly of the positioning assembly, thereby ensuring that the positioning assembly can be quickly and stably disassembled or installed, greatly improving the user's work efficiency.

[0036] Working principle: When using the die positioning structure for this punch press, the operator first places the die 2 on the surface of the punch press body 1. Then, by rotating the screw 4, the slider 5 slides inside the connecting rod 3, which in turn causes the clamping block 8 to contact the outer wall of the die 2. The clamping block 8 compresses the spring 7, causing it to undergo elastic deformation and store elastic potential energy, thereby achieving the positioning effect according to the size of different dies 2. When disassembling and assembling the positioning component, the operator first inserts the sliding column 10 into the slot 11. The engaging column 16 compresses the spring 12, causing it to undergo elastic deformation and providing an upward counterforce to the sliding column 10. At the same time, the operator rotates the knob 17, causing the engaging column 16 to rotate synchronously inside the slot 11, thereby achieving a quick fixation effect and facilitating the operator's quick assembly and disassembly of the positioning component.

[0037] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
