Description

Technical Field

[0001] This utility model relates to the field of new materials technology, specifically to an extrusion die with a self-locking function. Background Technology

[0002] An extrusion die is a special tool used in the extrusion process of metal materials. It is mainly used to extrude metal billets from the die holes or gaps under triaxial non-uniform compressive stress, causing them to undergo plastic deformation, thereby obtaining extruded products with the required shape, size and properties.

[0003] Traditional extrusion dies present several unresolved issues. During extrusion, the die needs to stably hold the billet or workpiece in place to prevent displacement under high pressure, thus ensuring the quality of the extruded product. However, many existing dies are not ideal in this regard, lacking effective self-locking mechanisms. When the die is subjected to significant extrusion force, the billet is prone to loosening or shifting. This not only leads to deviations in the shape and size of the extruded product, affecting product quality, but may even damage the die, increasing production costs and extending production cycles. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion die with a self-locking function, so as to facilitate the self-locking of the die.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an extrusion die with a self-locking function, comprising a base plate, a controller disposed on the top of the base plate, a support plate fixedly mounted on the top of the base plate, and an extrusion assembly disposed between the base plate and the support plate.

[0006] Preferably, the extrusion assembly includes: a self-locking component disposed on the top of the base plate; and a buffer component disposed on the top of the support plate.

[0007] Preferably, the self-locking component includes: a base, fixedly installed on the top of the base plate; a motor, fixedly installed on one side of the base; and a supporting base plate, fixedly installed on the bottom of the base.

[0008] Preferably, the base has an internal mounting cavity, and the top of the base has symmetrical sliding openings. A lower mold is fixedly installed on the top of the supporting base plate, and horizontal plates are symmetrically fixedly installed on both sides of the lower mold. The output end of the motor is provided with a long shaft, and the other end of the long shaft movably passes through one side of the outer wall of the base, one side of the inner wall of the base, and extends to the other side of the inner wall of the base. It is rotatably connected to the base through a bearing. Threaded grooves are symmetrically opened at both ends of the long shaft.

The slider is slidably connected to the base through the sliding opening. A connecting block is fixedly installed on the top of the slider, and a connecting frame is fixedly installed on the top of the connecting block.

[0009] When the electric actuator retracts, it pushes the movable plate through the isosceles actuator. The movable plate drives the slide bar to slide in the groove of the connecting frame, causing the clamping plate to move in the opposite direction and fix the horizontal plates on both sides of the lower mold.

[0010] Preferably, an electric actuator is fixedly fitted on one side of the connecting frame, and movable openings are respectively provided at the top and bottom of the connecting frame. A sliding groove is provided on the other side of the connecting frame, and the sliding groove is connected to the movable opening. An isosceles actuator is fixedly installed at the telescopic end of the electric actuator, and movable plates are slidably connected to both ends of the isosceles actuator. The outer side of the movable plate movably passes through the movable opening, and a slide rod is fixedly installed on the other side of the movable plate. The slide rod is slidably connected to the connecting frame through the sliding groove. A clamping plate is fixedly installed on the outer side of the movable plate and the slide rod, and on the other side of the slide rod.

[0011] The electric actuator is fixedly sleeved on one side of the connecting frame. When the electric actuator starts to extend or retract, it can precisely drive the isosceles actuator connected to it.

[0012] Preferably, the buffer component includes: guide rods, symmetrically and equidistantly mounted on the top of the base; and a cylinder, fixedly mounted on the bottom of the support plate.

[0013] Preferably, the top end of the guide rod is fixedly connected to the support plate, the telescopic end of the cylinder is fixedly installed with a connecting top frame, the top of the inner wall of the connecting top frame is symmetrically fixedly installed with fixed vertical plates, a connecting rod is fixedly installed between the fixed vertical plates, the outer wall of the connecting rod is symmetrically slidably fitted with a second movable block, the outer wall of the connecting rod is fitted with a spring, and the two ends of the spring are respectively fixedly connected to the second movable block.

[0014] The top of the guide rod is fixedly connected to the support plate, providing a stable support frame for the entire buffer system.

[0015] Preferably, a long push rod is movably provided at the bottom of the second movable block, and the other end of the long push rod is movably connected to a connecting top plate. An inner frame is fixedly installed on the top of the connecting top plate, and the inner frame is slidably fitted inside the connecting top frame. The connecting top plate is slidably fitted with a guide rod, and an upper mold is fixedly installed at the bottom of the connecting top plate. Horizontal plates are symmetrically fixedly installed on both sides of the upper mold.

[0016] Through the connection between the long push rod and the connecting top plate, the spring's buffering effect effectively reduces the impact on the upper mold, protecting it from damage.

[0017] This utility model provides an extrusion die with a self-locking function. It has the following beneficial effects:

[0018] (1) This utility model is started by a motor, which drives the long shaft to rotate. Since the long shaft has threaded grooves at both ends and is threadedly connected to the moving block 1, the moving block 1 will move along the long shaft when the long shaft rotates. The slider at the top of the moving block 1 slides in the sliding port of the base, so that the position of the connecting frame contacts the horizontal plate 1 and the horizontal plate 2. The electric push rod is started to retract and pull the isosceles push rod. The isosceles push rod pushes the movable plates at both ends. The movable plates slide in the movable port of the connecting frame and drive the slide rod to slide in the sliding groove of the connecting frame. The slide rod drives the clamping plate to move in the opposite direction. The clamping plates on both sides fix the horizontal plate 1 and the horizontal plate 2, achieving the effect of self-locking.

[0019] (2) By starting the cylinder, the upper mold moves downward under external pressure. The connecting top plate slides downward along the guide rod. The connecting top plate pushes the moving block two to slide on the connecting rod through the long push rod. The spring is compressed. The compression of the spring absorbs part of the energy during the downward movement of the upper mold, which plays a buffering role and reduces the impact force on the mold during the extrusion, thus protecting the mold and equipment.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1:

[0030] A preferred embodiment of the extrusion die with self-locking function provided by this utility model is, for example... Figure 1-4As shown: An extrusion die with a self-locking function includes a base plate 1, a controller 2 disposed on the top of the base plate 1, a support plate 3 fixedly mounted on the top of the base plate 1, and an extrusion assembly 4 disposed between the base plate 1 and the support plate 3. The extrusion assembly 4 includes: a self-locking component 41 disposed on the top of the base plate 1; and a buffer component 42 disposed on the bottom of the support plate 3. The self-locking component 41 includes: a base 411 fixedly mounted on the top of the base plate 1; a motor 412 fixedly mounted on one side of the base 411; and a supporting base plate 413 fixedly mounted on the base. The top of base 411; an installation cavity is provided inside base 411, and sliding openings are symmetrically provided on the top of base 411. A lower mold 414 is fixedly installed on the top of support base plate 413, and horizontal plates 415 are symmetrically fixedly installed on both sides of the lower mold 414. A long shaft 416 is provided at the output end of motor 412. The other end of long shaft 416 movably passes through one side of the outer wall of base 411, one side of the inner wall of base 411, and extends to the other side of the inner wall of base 411, and is rotatably connected to base 411 through bearings. The two ends of long shaft 416 are respectively Symmetrically threaded grooves are provided. A movable block 417 is threadedly connected to the long shaft 416 through the threaded grooves. A slider 418 is fixedly installed on the top of the movable block 417. The slider 418 is slidably connected to the base 411 through a sliding port. A connecting block 419 is fixedly installed on the top of the slider 418. A connecting frame 4111 is fixedly installed on the top of the connecting block 419. An electric actuator 4112 is fixedly sleeved on one side of the connecting frame 4111. Movable openings are provided at the top and bottom of the connecting frame 4111, and a sliding port is provided on the other side of the connecting frame 4111. The groove and the sliding groove are connected to the movable opening. An isosceles push rod 4113 is fixedly installed at the telescopic end of the electric push rod 4112. Movable plates 4114 are slidably connected to both ends of the isosceles push rod 4113. The outer side of the movable plate 4114 moves through the movable opening. A slide rod 4115 is fixedly installed on the other side of the movable plate 4114. The slide rod 4115 is slidably connected to the connecting frame 4111 through the sliding groove. A 4117 is fixedly installed on the outer side of the movable plate 4114 and the slide rod 4115. A clamping plate 4116 is fixedly installed on the other side of the slide rod 4115.

[0031] Furthermore, in this embodiment, the motor 412 is activated, driving the long shaft 416 to rotate. Since the long shaft 416 has threaded grooves at both ends and is threadedly connected to the first moving block 417, the first moving block 417 moves along the long shaft 416 when the long shaft 416 rotates. The slider 418 at the top of the first moving block 417 slides within the sliding opening of the base 411, ensuring the stability of the movement. The slider 418 drives the connecting frame 4111 to move through the connecting block 419, thereby adjusting the position of the connecting frame 4111. When the first horizontal plate 415 and the second horizontal plate 4213 come into contact, the electric actuator 4112 is activated and retracts, pulling the isosceles actuator 4113. The isosceles actuator 4113 pushes the movable plates 4114 at both ends. The movable plates 4114 slide in the movable opening of the connecting frame 4111 and drive the slide rod 4115 to slide in the slide groove of the connecting frame 4111. The slide rod 4115 drives the clamping plate 4116 to move in the opposite direction. The clamping plates 4116 on both sides fix the first horizontal plate 415 and the second horizontal plate 4213.

[0032] Example 2:

[0033] Based on Embodiment 1, a preferred embodiment of the extrusion die with a self-locking function provided by this utility model is as follows: Figure 1-4 As shown: The buffer component 42 includes: guide rods 421, symmetrically and equidistantly installed on the top of the base 411; cylinders 422, fixedly installed on the bottom of the support plate 3; the top end of the guide rods 421 is fixedly connected to the support plate 3; a connecting top frame 423 is fixedly installed on the telescopic end of the cylinder 422; fixed vertical plates 424 are symmetrically fixedly installed on the top of the inner wall of the connecting top frame 423; connecting rods 425 are fixedly installed between the fixed vertical plates 424; movable blocks 426 are symmetrically slidably sleeved on the outer wall of the connecting rods 425; and springs 426 are sleeved on the outer wall of the connecting rods 425. 28. The two ends of the spring 428 are fixedly connected to the second movable block 426. The bottom of the second movable block 426 is movably provided with a long push rod 427. The other end of the long push rod 427 is movably connected to a connecting top plate 429. The top of the connecting top plate 429 is fixedly installed with an inner frame 4211. The inner frame 4211 is slidably sleeved inside the connecting top frame 423. The connecting top plate 429 is slidably sleeved with the guide rod 421. The bottom of the connecting top plate 429 is fixedly installed with an upper mold 4212. The two sides of the upper mold 4212 are symmetrically fixedly installed with a second horizontal plate 4213.

[0034] Furthermore, in this embodiment, by activating cylinder 422, the upper mold 4212 moves downward under external pressure, the connecting top plate 429 slides downward along guide rod 421, and the connecting top plate 429 pushes the moving block 426 to slide on connecting rod 425 via long push rod 427. The spring 428 is compressed, and the compression of the spring 428 absorbs some of the energy during the downward movement of the upper mold 4212, playing a buffering role, reducing the impact force on the mold during extrusion, and protecting the mold and equipment. At the same time, if pressure fluctuations occur during the extrusion process, the spring 428 can also adjust the position of the upper mold 4212 by extension and retraction to ensure the stability of extrusion.

[0035] During use, the die is placed in a suitable working position via the base plate 1, and the controller 2 is in standby mode, capable of controlling and monitoring the entire extrusion process. The support plate 3 provides stable support for the upper buffer component 42. The billet to be extruded is placed on the lower die 414, which is fixed to the base 411 via the support base plate 413. Before extrusion begins, the cylinder 422 is in its initial state, and its telescopic end connecting top frame 423 is connected to the upper die 4212 via components such as the fixed vertical plate 424, connecting rod 425, moving block 2 426, spring 428, long push rod 427, and connecting top plate 429. The guide rod 421 ensures the connection top plate 429. The accuracy of the vertical movement of the upper die 4212 is ensured. When extrusion begins, the cylinder 422 is activated, and the upper die 4212 moves downward under external pressure. The connecting top plate 429 slides downward along the guide rod 421. The connecting top plate 429 pushes the moving block 426 to slide on the connecting rod 425 via the long push rod 427. The spring 428 is compressed. The compression of the spring 428 absorbs some of the energy during the downward movement of the upper die 4212, playing a buffering role and reducing the impact force on the die during extrusion, protecting the die and equipment. At the same time, if pressure fluctuations occur during extrusion, the spring 428 can also adjust the position of the upper die 4212 by extending and retracting. To ensure the stability of the extrusion, motor 412 starts, driving the long shaft 416 to rotate. Since the long shaft 416 has threaded grooves at both ends and is threadedly connected to the first moving block 417, the first moving block 417 moves along the long shaft 416 as it rotates. The slider 418 at the top of the first moving block 417 slides within the sliding opening of the base 411, ensuring stable movement. The slider 418 drives the connecting frame 4111 to move via the connecting block 419, thereby adjusting the position of the connecting frame 4111, which then contacts the first horizontal plate 415 and the second horizontal plate 4213. The electric actuator 4112 starts, retracting and pulling the isosceles actuator 4113, which then pushes... The movable plates 4114 at both ends slide within the movable opening of the connecting frame 4111, and drive the slide rod 4115 to slide within the slide groove of the connecting frame 4111. The slide rod 4115 drives the clamping plate 4116 to move in the opposite direction. The clamping plates 4116 on both sides fix the first horizontal plate 415 and the second horizontal plate 4213. During the extrusion process, the reaction force generated by the pressure on the billet will cause the clamping plate 4116 to tend to move outward. However, due to the thrust of the electric push rod 4112 and the connection structure of the isosceles push rod 4113 and the movable plate 4114, the clamping plate 4116 remains stable, realizing the self-locking function and preventing the billet from moving during the extrusion process.

[0036] 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.
