Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, specifically to a cold extrusion forming hydraulic press. Background Technology

[0002] A cold extrusion forming hydraulic press is a mechanical device that uses high-pressure hydraulic fluid to drive a piston for cold extrusion forming. It is widely used in the field of plastic processing of metal materials, such as the manufacturing industries of automotive parts, electronic product casings, and hardware tools. Its core function is to convert mechanical energy into pressure energy through high-pressure hydraulic fluid, apply huge pressure to the metal material, and cause it to undergo plastic deformation in the mold, thereby obtaining parts of the required shape and size.

[0003] Cold extrusion forming hydraulic presses require the use of molds and die heads. The die head is fixed to the pressure plate of the cold extrusion forming hydraulic press, while the mold is fixed to the worktable of the cold extrusion forming hydraulic press through a clamping mechanism. When the workpiece to be cold extruded is large in size and complex in shape, the size and structure of the mold will also increase and become more complex to meet the forming requirements of the workpiece. When the workpiece is large, the volume and weight of the mold will increase significantly, reaching several hundred kilograms or even more. It is inconvenient for the operator to move the mold back and forth between the worktable and the storage box. This problem should be addressed in a targeted manner.

[0004] Therefore, a cold extrusion forming hydraulic press is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cold extrusion forming hydraulic press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A cold extrusion forming hydraulic press includes a base, a press body, a die head, and a mold. The die head is fixedly mounted on the bottom of the pressure plate of the press body. The bottom of the pressure plate of the press body and the surface of the die head are provided with a material ejection mechanism for ejecting material from the die head. One side surface of the press body and the surface of its worktable are provided with a storage auxiliary mechanism for storing and horizontally moving molds. The worktable of the press body is provided with a clamping mechanism for clamping and fixing the molds.

[0008] Furthermore, the stripping mechanism includes a longitudinal guide rail. The bottom of the pressure plate of the hydraulic press body is fixedly provided with the longitudinal guide rail. A longitudinal slider is slidably provided inside the longitudinal guide rail, and the longitudinal slider and the longitudinal guide rail are slidably installed. A return spring is fixedly provided on the opposite surface of the top of the longitudinal slider and the inner top of the longitudinal guide rail. A connecting rod is fixedly provided on the surface of the longitudinal slider. A moving ring is fixedly provided at the other end of the connecting rod, and the moving ring is adapted to the die head.

[0009] Furthermore, the storage auxiliary mechanism includes a storage box, which is fixedly provided on one side surface of the hydraulic press body. A sliding groove is provided on one side inner wall of the storage box. A motor is fixedly provided on the top of the storage box. A threaded rod is rotatably provided on the inner wall of the sliding groove, and the top end of the threaded rod passes through the surface of the storage box and is fixedly connected to the output end of the motor. A movable block is threadedly connected to the surface of the threaded rod, and the movable block is slidably installed with the sliding groove. A support plate is fixedly provided on the surface of the movable block.

[0010] Furthermore, two sets of first transverse guide rails are fixedly provided on the top of the support plate, and two sets of second transverse guide rails are fixedly provided on the worktable of the hydraulic press body. The two sets of second transverse guide rails correspond to the two sets of first transverse guide rails respectively. A horizontal plate is slidably provided inside the two sets of second transverse guide rails, and the mold is set on the top of the horizontal plate.

[0011] Furthermore, the clamping mechanism includes a fixing block and an L-shaped guide rail.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model enables the storage of grinding molds through a storage auxiliary mechanism, which allows the grinding molds to move longitudinally. When the grinding molds move to the outside of the storage auxiliary mechanism, the storage auxiliary mechanism allows the grinding molds to be moved horizontally to the top of the worktable of the hydraulic press body. When the grinding molds correspond to the die head, the clamping mechanism clamps and fixes the grinding molds. When storing the grinding molds, the clamping mechanism releases the clamping mechanism, and the grinding molds are pushed horizontally to the top of the storage auxiliary mechanism. At this time, the storage auxiliary mechanism moves the grinding molds downward into its interior, thus completing the storage of the grinding molds. Relevant personnel can store the grinding molds without having to move them, which saves more effort and provides convenience for relevant personnel. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 4 As shown, a cold extrusion forming hydraulic press includes a base 1, a press body 2, a die head 3, and a mold 4. The die head 3 is fixedly disposed at the bottom of the pressure plate of the press body 2. The bottom of the pressure plate of the press body 2 and the surface of the die head 3 are provided with a stripping mechanism 5 for stripping material from the die head 3. Figure 1 , Figure 2 As shown, specifically, the unloading mechanism 5 includes a longitudinal guide rail 501. The bottom of the pressure plate of the hydraulic press body 2 is fixedly provided with the longitudinal guide rail 501. A longitudinal slider 502 is slidably provided inside the longitudinal guide rail 501, and the longitudinal slider 502 and the longitudinal guide rail 501 are slidably installed. A return spring 503 is fixedly provided on the opposite surface of the top of the longitudinal slider 502 and the inner top of the longitudinal guide rail 501. A connecting rod 504 is fixedly provided on the surface of the longitudinal slider 502. A moving ring 505 is fixedly provided at the other end of the connecting rod 504, and the moving ring 505 is adapted to the die head 3.

[0025] More specifically, the pressure plate of the hydraulic press body 2 presses down, causing the die head 3, the longitudinal guide rail 501, and the moving ring 505 to move downwards simultaneously. The die head 3 is pressed down and embedded inside the mold 4, and the bottom of the moving ring 505 abuts against the top of the mold 4. Under the action of force, the longitudinal slider 502 squeezes the return spring 503. When the die head 3 moves upward and returns to its original position, the longitudinal slider 502 returns to its original position under the action of the return spring 503, thereby causing the connecting rod 504 and the moving ring 505 to return to their original positions. When the moving ring 505 returns to its original position, it applies a downward force to the material on the surface of the die head 3, thereby causing the material to fall off.

[0026] The hydraulic press body 2 has a storage auxiliary mechanism 6 on one side surface and the surface of its worktable for storing the grinding wheel 4 and for horizontally moving grinding wheel 4, such as... Figure 1 , Figure 2 and Figure 3As shown, specifically, the storage auxiliary mechanism 6 includes a storage box 601. The storage box 601 is fixedly mounted on one side surface of the hydraulic press body 2. A sliding groove 602 is formed on the inner wall of one side of the storage box 601. A motor 603 is fixedly mounted on the top of the storage box 601. A threaded rod 604 is rotatably mounted on the inner wall of the sliding groove 602. The top end of the threaded rod 604 penetrates the surface of the storage box 601 and is fixedly connected to the output end of the motor 603. A movable block 605 is threadedly connected to the surface of the threaded rod 604. The movable block 605 and the slide groove 602 are slidably installed. A support plate 606 is fixedly provided on the surface of the movable block 605. Two sets of first transverse guide rails 607 are fixedly provided on the top of the support plate 606. Two sets of second transverse guide rails 608 are fixedly provided on the worktable of the hydraulic press body 2. The two sets of second transverse guide rails 608 correspond to the two sets of first transverse guide rails 607 respectively. A horizontal plate 609 is slidably provided inside the two sets of second transverse guide rails 608. The mold 4 is provided on the top of the horizontal plate 609.

[0027] More specifically, when the motor 603 starts, its output drives the threaded rod 604 to rotate, thereby causing the movable block 605 to slide longitudinally, which in turn causes the support plate 606 to move longitudinally. The longitudinal movement of the support plate 606 allows the grinding mold 4 to move longitudinally inside the storage box 601, thus realizing the storage and removal of the grinding mold 4. When the support plate 606 moves to the top, the two sets of first transverse guide rails 607 correspond to the two sets of second transverse guide rails 608 respectively. At this time, the horizontal plate 609 is moved horizontally, thereby causing the grinding mold 4 on its surface to move. When the horizontal plate 609 slides into the interior of the two sets of first transverse guide rails 607, the grinding mold 4 is positioned above the support plate 606. Relevant personnel can store and retrieve the grinding mold 4 without having to move it, thus providing convenience.

[0028] The hydraulic press body 2 is equipped with a clamping mechanism 7 for clamping and fixing the grinding mold 4 on its worktable, such as... Figure 1 , Figure 4 As shown, specifically, the clamping mechanism 7 includes a fixing block 701 and an L-shaped guide rail 702. The fixing block 701 and the L-shaped guide rail 702 are fixedly provided on the worktable of the hydraulic press body 2. A stud 703 is threadedly connected to the L-shaped guide rail 702. A knob 704 is fixedly provided at one end of the stud 703. An abutment block 705 is provided at the other end of the stud 703. The abutment block 705 is correspondingly arranged with the fixing block 701. One side of the abutment block 705 is rotatably installed with one end of the stud 703. The bottom of the abutment block 705 is slidably installed with the surface of the L-shaped guide rail 702.

[0029] More specifically, rotating the knob 704 causes the stud 703 to rotate, thereby causing the abutment block 705 to move. When the mold 4 is located between the fixed block 701 and the abutment block 705, the abutment block 705 moves closer to one side of the mold 4 and abuts against that side, thereby clamping the mold 4. The L-shaped guide rail 702 can limit the abutment block 705. When the knob 704 is rotated, the stud 703 moves, thereby causing the abutment block 705 to move. The L-shaped guide rail 702 can limit the abutment block 705.

[0030] In summary: The storage auxiliary mechanism 6 can store the mold 4, and it also allows the mold 4 to move longitudinally. When the mold 4 moves to the outside of the storage auxiliary mechanism 6, it can be moved horizontally to the top of the worktable of the hydraulic press body 2. When the mold 4 corresponds to the die head 3, the clamping mechanism 7 clamps and fixes the mold 4. The hydraulic press body 2 starts, causing the die head 3 to extrude and shape the material on the mold 4. When the die head 3 presses down, it triggers the ejector mechanism 5. When the die head 3 returns to its original position, the ejector mechanism 5... Under its action, the material on the die head 3 can be detached, eliminating the need for personnel to remove the material from the die head 3, thus improving work efficiency. When storing the mold 4, the clamping mechanism 7 releases the clamp on the mold 4 and pushes the mold 4 horizontally, thereby pushing the mold 4 above the storage auxiliary mechanism 6. At this time, the storage auxiliary mechanism 6 moves the mold 4 downward into its interior, thus completing the storage of the mold 4. Personnel do not need to move the mold 4 to store it, which saves more effort and provides convenience for relevant personnel.
