Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die with a guiding mechanism. Background Technology

[0002] Antarctic stamping dies are key equipment for forming sheet metal, widely used in industries such as automotive, home appliances, and electronics. They work by using a press to drive the upper and lower dies to stamp sheet metal into parts of specific shapes. Their core function is to achieve high-precision, high-efficiency mass production, directly impacting the dimensional accuracy, surface quality, and production efficiency of the products.

[0003] In actual production, the guiding effect of stamping dies directly affects the forming quality and equipment stability. When the guiding mechanism wears, the clearance increases, or it is improperly adjusted, the fitting accuracy between the upper and lower dies will decrease significantly, leading to obvious misalignment during the stamping process. This guiding failure can cause burrs, wavy deformation, or dimensional deviations on the edges of stamped parts, and in severe cases, it can even cause sheet metal tearing or die collision damage. Especially in high-speed continuous stamping scenarios, guiding deviations can cause the feeding mechanism and the die to be out of sync, resulting in batches of scrap and forcing the production line to stop frequently for adjustments. In addition, long-term wear of the guiding mechanism will accelerate metal fatigue of key die components, shorten the die's service life, increase maintenance costs and the risk of production interruption, becoming a major bottleneck restricting stamping efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a stamping die with a guiding mechanism, which solves the problem of poor guiding effect of stamping dies.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping die with a guiding mechanism, comprising a mounting plate, a guide rod fixedly connected to the lower end of the mounting plate, a cylinder fixedly mounted inside the mounting plate, a die fixedly connected to the output end of the cylinder, a guide seat slidably sleeved on the outer side of the guide rod, a mounting seat fixedly connected to the side of the guide seats that are close to each other, a fixing plate fixedly connected to the lower end of the mounting seat, the fixing plate contacting the die, a limit frame slidably sleeved on the outer side of the mounting seat, the limit frame contacting the die, a threaded rod rotatably connected inside the limit frame, the threaded rod being threadedly connected to the mounting seat, a limit ring fixedly connected to the outer side of the threaded rod, a knob fixedly connected to the end of the threaded rod away from the mounting seat, the knob contacting the limit frame, and a limit mechanism provided on the limit frame.

[0006] Preferably, a guide block is fixedly connected to the upper end of the mounting base, and the guide block is slidably connected to the limiting frame. Through the design of the guide block, the limiting frame can be guided.

[0007] Preferably, the limiting ring contacts the limiting frame, and the limiting ring is movably connected to the mounting base. Through the design of the limiting ring, the threaded rod can drive the limiting frame to move.

[0008] Preferably, the limiting mechanism includes a positioning frame, with a positioning frame slidably sleeved on the outer side of the limiting frame, a positioning block fixedly connected to the side of the positioning frame near the knob, a fixing rod fixedly connected inside the positioning frame, a fixing block fixedly connected to the upper end of the limiting frame, and a spring provided on the outer side of the fixing rod. Through the design of the limiting mechanism, the limiting frame can remain stable when limiting the mold.

[0009] Preferably, the positioning frame is in contact with the knob, and the positioning block is slidably connected to the knob. Through the design of the positioning frame and the positioning block, the knob can be limited.

[0010] Preferably, the fixing block is slidably connected to the positioning frame and the fixing block is slidably connected to the fixing rod. The design of the fixing block can guide the positioning frame.

[0011] Preferably, one end of the spring contacts the positioning frame, and the other end of the spring contacts the fixing block. Through the design of the spring, the positioning frame can be driven to limit the knob.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides precise linear guidance for the mounting base by setting guide rods and guide seats, ensuring stable motion trajectory; at the same time, the configuration of fixed plate and limit frame forms a multi-limit structure, effectively constraining mold displacement deviation. This design significantly improves the guiding accuracy when the mold is closed, avoids problems such as burrs and dimensional deviations in stamped parts caused by misalignment, and solves the pain point of poor guiding effect of traditional stamping dies.

[0014] 2. This utility model, by setting up a positioning frame, positioning block, and spring, utilizes the spring force to drive the positioning block to accurately engage with the knob slot, achieving rapid locking of the knob. This structure effectively prevents the knob from loosening and causing displacement of the threaded rod, ensuring stable clamping force of the limit frame on the mold. It solves the problem of positional deviation caused by vibration or external force after the stamping mold is limited, thus improving the reliability of mold positioning.

[0020] 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.

[0021] Please see Figure 1-4 A stamping die with a guiding mechanism includes a mounting plate 1, a guide rod 11 fixedly connected to the lower end of the mounting plate 1, a cylinder 12 fixedly installed inside the mounting plate 1, a die 13 fixedly connected to the output end of the cylinder 12, a guide seat 2 slidably sleeved on the outer side of the guide rod 11, a mounting seat 3 fixedly connected to the side of the guide seats 2 that are close to each other, a fixing plate 31 fixedly connected to the lower end of the mounting seat 3, the fixing plate 31 contacting the die 13, and a limit frame 32 slidably sleeved on the outer side of the mounting seat 3, the limit frame 32 contacting the die 13.

[0022] Please see Figure 2-4 A guide block 33 is fixedly connected to the upper end of the mounting base 3. The guide block 33 is slidably connected to the limiting frame 32. The guide block 33 is designed to guide the limiting frame 32. A threaded rod 34 is rotatably connected inside the limiting frame 32. The threaded rod 34 is threadedly connected to the mounting base 3. A limiting ring 35 is fixedly connected to the outer side of the threaded rod 34. The limiting ring 35 is in contact with the limiting frame 32 and is movably connected to the mounting base 3. The limiting ring 35 is designed to allow the threaded rod 34 to move the limiting frame 32. A knob 36 is fixedly connected to the end of the threaded rod 34 away from the mounting base 3. The knob 36 is in contact with the limiting frame 32. A limiting mechanism 4 is provided on the limiting frame 32.

[0023] Please see Figure 2-4The limiting mechanism 4 includes a positioning frame 41. The positioning frame 41 is slidably sleeved on the outer side of the limiting frame 32. A positioning block 42 is fixedly connected to the side of the positioning frame 41 near the knob 36. The positioning frame 41 contacts the knob 36, and the positioning block 42 is slidably connected to the knob 36. Through the design of the positioning frame 41 and the positioning block 42, the knob 36 can be limited. A fixing rod 43 is fixedly connected inside the positioning frame 41. A fixing block 44 is fixedly connected to the upper end of the limiting frame 32. The fixing block 44 is slidably connected to the positioning frame 41 and the fixing rod 43. Through the design of the fixing block 44, the positioning frame 41 can be guided. A spring 45 is provided on the outer side of the fixing rod 43. One end of the spring 45 contacts the positioning frame 41, and the other end of the spring 45 contacts the fixing block 44. Through the design of the spring 45, the positioning frame 41 can be driven to limit the knob 36. Through the design of the limiting mechanism 4, the limiting frame 32 can remain stable when limiting the mold 13.

[0024] The specific implementation process of this utility model is as follows: In use, the cylinder 12 drives the mold 13 to contact the fixed plate 31, and then the positioning frame 41 is moved away from the knob 36, so that the positioning frame 41 drives the fixed rod 43 to slide in the fixed block 44, so that the positioning frame 41 squeezes the spring 45, and the positioning frame 41 drives the positioning block 42 to slide out of the knob 36, thus releasing the limitation on the knob 36;

[0025] By rotating the knob 36, the knob 36 drives the threaded rod 34 to rotate, causing the threaded rod 34 to move with the mounting base 3. This causes the threaded rod 34 to move the limiting frame 32, which then moves on the mounting base 3, thus limiting the mold 13. Then, by releasing the positioning frame 41, the spring force of the spring 45 can move the positioning frame 41, causing the positioning frame 41 to slide the positioning block 42 into the knob 36, thus restoring the limiting function of the knob 36.

[0026] When the cylinder 12 drives the mold 13 to move, the mold 13 can drive the fixed plate 31 and the limit frame 32 to move, which in turn can drive the mounting base 3 to move, and the mounting base 3 can drive the guide seat 2 to move on the guide rod 11, thus guiding the mold 13.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
