Description

Technical Field

[0001] This utility model belongs to the field of metal parts processing technology, specifically relating to a loading and unloading device for cold extrusion forming molds of metal parts. Background Technology

[0002] Metal parts refer to a collective term for metal blocks, rods, tubes, etc., of various specifications and shapes manufactured from metallic materials. Materials for metal parts include iron and steel, and non-ferrous metals (or non-ferrous metals). Iron and steel: Iron alloys with a carbon content of 2%–4.3% are cast iron, while iron alloys with a carbon content generally between 0.03% and 2% are steel. Various appropriate amounts of alloying elements are intentionally added to Fe-C alloys to improve the strength, hardness, wear resistance, and corrosion resistance of steel. Applications include machining, stamping, precision casting, powder metallurgy, metal injection molding, laser processing, electrical discharge machining, ultrasonic processing, electrolytic machining, particle beam machining, and ultra-high-speed machining. Similar to turning, milling, forging, casting, and grinding, CNC machining and CNC numerical control centers are all conventional machining processes. During the production and processing of metal parts, cold extrusion processing is required. However, currently, the cold extrusion of metal parts is carried out in a mold, which often requires manual assembly and disassembly. This makes it inconvenient to unload the cold-extruded metal parts in a timely manner, affecting the subsequent cold extrusion processing effect. Therefore, a loading and unloading device for cold extrusion forming molds of metal parts is needed. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a loading and unloading device for cold extrusion forming molds of metal parts. This solves the problem that in current cold extrusion processing of metal parts, since the metal parts are cold extruded and formed inside the mold, the mold often needs to be assembled and disassembled manually, which makes it inconvenient to unload the cold extruded metal parts in a timely manner, thus affecting the subsequent cold extrusion processing effect of metal parts.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a loading and unloading device for a cold extrusion forming die for metal parts, comprising a processing shell, a first electric push rod fixedly installed on both sides of the inner wall of the processing shell, a connecting plate fixedly connected to one end of the first electric push rod, a forming die fixedly installed on one side of the connecting plate, a die forming cavity opened on the surface of the forming die, an insertion hole opened on one side of the forming die, an insertion rod fixedly installed on one side of the forming die, a support frame fixedly installed on the surface of the processing shell, an electric hydraulic push rod fixedly installed on the surface of the support frame, a connecting plate fixedly connected to one end of the electric hydraulic push rod, a forming punch fixedly installed at the bottom of the connecting plate, a U-shaped support block fixedly installed on the back of the processing shell, a second electric push rod fixedly installed on the inner wall of the U-shaped support block, a discharge push plate fixedly connected to one end of the second electric push rod, and a discharge groove opened on the inner wall of the processing shell.

[0005] Preferably, the front hinge of the processing shell is connected to a protective baffle, and a handle is fixedly installed on one side of the protective baffle.

[0006] Preferably, there are four sockets and four insertion rods, and the sockets and insertion rods are divided into groups of two.

[0007] Preferably, the electro-hydraulic push rod is connected to the forming punch via a connecting plate, and the forming punch is located above the forming mold.

[0008] Preferably, a sound insulation plate is fixedly installed on the inner wall of the processing shell.

[0009] Preferably, an anti-slip protrusion is fixedly installed on one side of the unloading push plate, and the unloading push plate is located inside the processing shell.

[0010] Preferably, mounting plates are fixedly installed on both sides of the processing shell, and mounting grooves are formed on the surface of the mounting plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The first electric push rod can drive the forming mold to contract and move. The insert rod is inserted into the insertion hole to assemble the two forming molds. Conversely, the insert rod is moved out of the insertion hole to separate and disassemble the two forming molds. The second electric push rod drives the unloading push plate to move and push the metal parts, so that the metal parts are moved out of the processing shell along the inclined discharge groove, and the metal parts are unloaded. This avoids the need for manual assembly and disassembly of the molds, and facilitates timely unloading of the metal parts after cold extrusion forming, ensuring the effect of subsequent cold extrusion processing of metal parts.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides the following technical solution: a loading and unloading device for a cold extrusion forming mold of metal parts, including a processing shell 1, a first electric push rod 4 fixedly installed on both sides of the inner wall of the processing shell 1, a connecting plate 5 fixedly connected to one end of the first electric push rod 4, a forming mold 6 fixedly installed on one side of the connecting plate 5, a mold forming cavity 7 opened on the surface of the forming mold 6, an insertion hole 8 opened on one side of the forming mold 6, an insertion rod 9 fixedly installed on one side of the forming mold 6, a support frame 10 fixedly installed on the surface of the processing shell 1, an electric hydraulic push rod 11 fixedly installed on the surface of the support frame 10, a connecting plate 12 fixedly connected to one end of the electric hydraulic push rod 11, a forming punch 13 fixedly installed at the bottom of the connecting plate 12, a U-shaped support block 14 fixedly installed on the back of the processing shell 1, a second electric push rod 15 fixedly installed on the inner wall of the U-shaped support block 14, a discharge push plate 16 fixedly connected to one end of the second electric push rod 15, and a discharge groove 17 opened on the inner wall of the processing shell 1.

[0021] The activation of the first electric push rod 4 can move the connecting plate 5 and the forming mold 6. After the two forming molds 6 are moved and adjusted, the two sets of insert rods 9 can be inserted into the two sets of insert holes 8, assembling the two forming molds 6 and improving the sealing of the assembly. This facilitates the use of the forming molds 6. After assembly, the operator can place the metal part blank into the forming cavity 7 of the mold. The activation of the electric hydraulic push rod 11, through the connecting plate 12, can drive the forming punch 13 to adjust its lifting motion, allowing the forming punch 13 to perform cold extrusion processing on the metal part blank in the forming cavity 7 of the forming mold 6. The metal part blank in the forming cavity 7 is cold extruded and formed by pressure. After the metal part is cold extruded and formed, the activation of the first electric push rod 4, through the connecting plate 5, can move the forming mold 6. The retraction and reset process removes the insert rod 9 from the insertion hole 8, thereby separating the two forming molds 6 and disassembling them. After disassembly, the metal parts in the forming cavity 7 of the mold fall into the processing shell 1. At this time, the second electric push rod 15 is activated to drive the unloading push plate 16 to move. After adjustment, the unloading push plate 16 located in the processing shell 1 can push the cold-extruded metal parts in the processing shell 1, causing the metal parts to fall into the discharge groove 17 and move out of the processing shell 1 along the inclined discharge groove 17, thereby unloading the metal parts. This avoids the need for manual assembly and disassembly of the mold, facilitates timely unloading of the cold-extruded metal parts, and ensures the effect of subsequent cold extrusion processing of metal parts. All electrical equipment in this device is powered by an external power supply.

[0022] In one aspect of this embodiment, two sets of insert rods 9 can be inserted into two sets of insert holes 8 to assemble two molding molds 6, thereby improving the sealing of the molding mold 6 assembly and facilitating the use of the molding mold 6.

[0023] In one aspect of this embodiment, the protective baffle 2 can be moved by the handle 3, thereby opening or closing the processing shell 1 to facilitate the handling of metal part blanks. At the same time, the protective baffle 2 can protect the inside of the processing shell 1 to prevent the metal part blanks from splashing during the cold extrusion process.

[0024] In one aspect of this embodiment, after the electric hydraulic push rod 11 is started, it can drive the forming punch 13 to perform lifting and lowering motion adjustment through the connecting plate 12, so that the forming punch 13 performs cold extrusion processing on the metal part blank in the forming cavity 7 of the forming mold 6, and the metal part blank in the forming cavity 7 is cold extruded and formed by pressure.

[0025] In one aspect of this embodiment, the sound insulation plate inside the processing shell 1 can enhance the sound insulation effect inside the processing shell 1 and prevent the metal part blank from generating large noise during the cold extrusion process.

[0026] In one aspect of this embodiment, the mounting plate 18 can be fixed to the ground via a mounting slot, thereby installing and securing the device.

[0027] In one aspect of this embodiment, after the unloading push plate 16 located inside the processing shell 1 is moved and adjusted, the unloading push plate 16 can push the metal parts that have been cold extruded and formed inside the processing shell 1, thereby unloading the metal parts, and the anti-slip protrusions can enhance the anti-slip effect of the unloading push plate 16.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
