Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, specifically a cold heading mold that is easy to replace. Background Technology

[0002] A cold heading machine is a forging and forming device that thickens the top of bars or wires at room temperature. It is a specialized machine mainly used for mass production of fasteners such as nuts and bolts. The cold heading machine uses the cold heading method to upset the head of bolts and screws, which can minimize cutting work and directly form them into the required shape and size. This not only saves a lot of materials, but also greatly improves production efficiency and significantly improves the mechanical strength of the upset parts. Therefore, each branch mechanism in the cold heading machine is a very important component.

[0003] A search revealed Chinese Patent No. CN 220920809 U, which discloses a cold heading machine with an easy-to-change mold. The machine includes a body, a base fixedly connected to the top of the body, and a fixed frame fixedly connected to the top of the base. The fixed frame contains an easy-to-change component, which includes a fixed rod fixedly connected inside the fixed frame. Multiple movable blocks are slidably connected to the outside of the fixed rod. The advantages of this invention are: The mold can be changed according to the workpiece to be processed. The mold is placed between a first clamping block and a second clamping block. Through the magnetic attraction and magnets inside the first and second clamping blocks, the movable blocks move outside the fixed rod, clamping the mold. This easily achieves mold replacement, reducing equipment costs and improving the practicality of the cold heading machine.

[0004] However, the existing technology described above still has the following problems:

[0005] Although the first and second clamping blocks work together to move the moving block outside the fixed rod through magnetic attraction and magnetism, allowing the first and second clamping blocks to hold the mold and thus easily change the mold, thereby reducing equipment costs and improving the practicality of the cold heading machine, the process of changing the cold heading mold still requires manual handling of each mold. This makes the change of the cold heading mold inconvenient and reduces the efficiency of cold heading mold replacement.

[0006] Therefore, this utility model provides a cold heading mold that is easy to replace, in order to solve the above problems. Utility Model Content

[0007] This utility model provides a cold heading die that is easy to replace, aiming to solve the problems mentioned in the background art, such as the need for manual handling of each cold heading die during replacement, which makes the replacement of cold heading dies inconvenient and reduces the efficiency of cold heading die replacement.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cold heading mold that is easy to replace, comprising a horizontally arranged working base plate, a drive mechanism mounted on the upper surface of the working base plate, a mounting plate mounted on one side of the upper surface of the working base plate, a mold assembly mounted in a path array on one side of the mounting plate, and a unloading mechanism mounted on the surface of the drive mechanism.

[0009] The unloading mechanism includes two fixed plates mounted on the surface of the mold assembly, a drive motor disposed inside one of the fixed plates, a drive rod disposed at the output end of the drive motor, a flip plate disposed on the surface of the drive rod, insertion slots arranged in a path array on the surface of the flip plate, a storage slot disposed inside the insertion slot, a fixing ring connected inside the insertion slot, a servo motor disposed inside the flip plate, a bidirectional threaded rod disposed at the output end of the servo motor and connected inside the flip plate, and a discharge mechanism mounted on the middle of the upper surface of the working base plate.

[0010] The retaining ring is connected to the bidirectional threaded rod.

[0011] Furthermore, in the aforementioned easily replaceable cold heading die, the drive mechanism includes two sliding grooves formed at the two edges of the upper surface of the working base plate, a sliding block connected inside the sliding groove, a threaded rod disposed inside the two sliding grooves, and an adjusting motor disposed inside the sliding groove and whose output end is connected to the threaded rod.

[0012] Furthermore, in the aforementioned easily replaceable cold heading die, the die assembly includes a left mounting block connected to the surfaces of two sliding blocks, a connecting block connected in a path array to one side of the left mounting block, a left die disposed inside the connecting block, and a limiting plate disposed on the surface of the left die and corresponding to the insertion slot.

[0013] Furthermore, in the aforementioned easily replaceable cold heading mold, the mold assembly also includes a right mounting block connected to one side of the mounting plate surface, a right mold connected to one side of the right mounting block in a path array and corresponding to the left mold, and a feed chute opened on one side of the right mounting block and the mounting plate (2).

[0014] Furthermore, in the aforementioned easily replaceable cold heading mold, the discharge mechanism includes a storage box connected to the middle of the upper surface of the working base plate, a guide groove disposed on the surface of the storage box and corresponding to the left mold, a discharge plate disposed inside the guide groove, and a pushing mechanism mounted on the surface of the storage box.

[0015] Furthermore, in the aforementioned easily replaceable cold heading mold, the pushing mechanism includes a pushing motor mounted on one side of the storage box, a drive gear disposed at the output end of the pushing motor, a drive rack meshing with the surface of the drive gear, and a locking block connected to the drive rack and the discharge plate.

[0016] Beneficial effects:

[0017] By configuring the mold assembly and unloading mechanism, the drive motor is activated, causing the tilting plate to rotate the left mold, which then inserts into the receiving slot. A servo motor drives a bidirectional threaded rod to move the fixing ring, removing it from the limiting plate's position. This allows the left mold to fall into the guide slot. A push motor then drives a drive gear to rotate a rack, causing a locking block to move the ejector plate within the receiving slot, thus unloading the left mold from the guide slot. This eliminates the need for manual handling when removing the cold heading mold; the ejector plate unloads the entire mold, improving the efficiency of cold heading mold replacement.

[0025] 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.

[0026] This utility model provides a cold heading die that is easy to replace, such as Figures 1 to 4 As shown, the cold heading mold includes a horizontally arranged working base plate 1, a drive mechanism mounted on the upper surface of the working base plate 1, a mounting plate 2 mounted on one side of the upper surface of the working base plate 1, a mold assembly mounted in a path array on one side of the mounting plate 2, and a unloading mechanism mounted on the surface of the drive mechanism.

[0027] The unloading mechanism includes two fixed plates 3 mounted on the surface of the mold assembly, a drive motor 4 set inside one of the fixed plates 3, a drive rod 5 set at the output end of the drive motor 4, a flip plate 6 set on the surface of the drive rod 5, insertion slots 7 arranged in a path array on the surface of the flip plate 6, a storage slot 8 set inside the insertion slot 7, a fixing ring 9 connected inside the insertion slot 7, a servo motor 10 set inside the flip plate 6, a bidirectional threaded rod 11 set at the output end of the servo motor 10 and connected inside the flip plate 6, and a discharge mechanism mounted on the middle of the upper surface of the working base plate 1.

[0028] The retaining ring 9 is connected to the bidirectional threaded rod 11.

[0029] When it is necessary to replace the left mold 18 in the mold assembly, start the drive motor 4, so that its output end drives the drive rod 5 to rotate on the surface of the fixed plate 3, which drives the flip plate 6 to rotate. This causes the flip plate 6 to drive the left mold 18, which is inserted into the insertion slot 7, to rotate, so that the left mold 18 is disengaged from the connecting block 17. Then, start the servo motor 10, so that its output end drives the bidirectional threaded rod 11 to rotate, thereby causing the two fixing rings 9 to move away from each other, so that the fixing rings 9 no longer limit the left mold 18.

[0030] The discharge mechanism includes a storage box 22 connected to the middle of the upper surface of the working base plate 1, a guide groove 23 disposed on the surface of the storage box 22 and corresponding to the left mold 18, a discharge plate 24 disposed inside the guide groove 23, and a pushing mechanism installed on the surface of the storage box 22.

[0031] When the retaining ring 9 no longer limits the left mold 18, the left mold 18 is disengaged from the insertion groove 7 and inserted into the guide groove 23. The guide groove 23 supports and limits the left mold 18.

[0032] The pushing mechanism includes a pushing motor 25 installed on one side of the storage box 22, a drive gear 26 disposed at the output end of the pushing motor 25, a drive rack 27 meshing with the surface of the drive gear 26, and a locking block connected to the drive rack 27 and the discharge plate 24.

[0033] After the left mold 18 is inserted into the guide groove 23, the drive motor 25 is started, causing its output end to drive the drive gear 26 to rotate inside the storage box 22. This causes the drive rack 27 to rotate inside the storage box 22, which in turn causes the locking block to slide on the inner wall of the storage box 22. This causes the ejector plate 24 to slide on the inner bottom wall of the guide groove 23, pushing the left mold 18 inserted into the guide groove 23 to move and remove the left mold 18 from the storage box 22. This eliminates the need for manual removal of the left mold 18 when it is replaced, thus improving the efficiency of the left mold 18 replacement.

[0034] For example, a cold heading die that can be easily replaced can be used to perform cold heading stamping on materials, such as... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the drive mechanism includes two sliding grooves 12 opened at the two edges of the upper surface of the working base plate 1, a sliding block 13 connected inside the sliding groove 12, a threaded rod 14 disposed inside the two sliding grooves 12, and an adjusting motor 15 disposed inside the sliding grooves 12 and whose output end is connected to the threaded rod 14.

[0035] By starting the regulating motor 15, its output end drives the corresponding threaded rod 14 to rotate, causing the sliding block 13 to slide inside the sliding groove 12, which in turn drives the left mounting block 16 to slide on the surface of the working base plate 1, thereby moving the left mold 18 to the inside of the right mold 21 for cold heading of the material inside the right mold 21.

[0036] The mold assembly includes a left mounting block 16 connected to the surfaces of two sliding blocks 13, a connecting block 17 connected to one side of the left mounting block 16 in a path array, a left mold 18 disposed inside the connecting block 17, and a limiting plate 19 disposed on the surface of the left mold 18 and corresponding to the insertion slot 7.

[0037] By setting the connecting block 17, the left mold 18 is inserted into the inside of the connecting block 17 and connected to the left mounting block 16. The left mold 18 is limited by the setting of the limiting plate 19. Thus, through the mutual cooperation between the limiting plate 19 and the fixing ring 9, the installation of the left mold 18 and the insertion groove 7 is more stable, and the left mold 18 is more stable during use.

[0038] The mold assembly also includes a right mounting block 20 connected to one side of the surface of the mounting plate 2, a right mold 21 connected to one side of the right mounting block 20 in a path array and corresponding to the left mold 18, and a feed chute opened on one side of the right mounting block 20 and the mounting plate 2.

[0039] The material is inserted into the inside of the right mold 21 through the feed chute to prepare for the cold heading process of the left mold 18.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
