Description

Technical Field

[0001] This utility model relates to the field of punching and shearing machine technology, and in particular to a hydraulic combined punching and shearing machine. Background Technology

[0002] Hydraulic combined punching and shearing machine is a commonly used metal processing equipment. Powered by a hydraulic system, it can integrate the functions of punching and trimming metal sheets and shearing profiles such as angle steel and channel steel. It is suitable for small and medium-sized hardware processing, steel structure fabrication and other scenarios, and can improve the processing efficiency of metal parts.

[0003] Hydraulic combined punching and shearing machines are a highly efficient piece of equipment that integrates punching, shearing and other functions. They are widely used in the modern metal processing field. The realization of their multi-functionality depends heavily on the frequent replacement of the corresponding lower die (die) for different processing needs (such as different hole diameters and profile specifications).

[0004] However, the installation and fixing methods of the lower die in existing hydraulic combined punching and shearing machines have significant defects, severely restricting further improvements in equipment efficiency. Specifically, the currently commonly used lower die fixing structure mainly relies on traditional bolt fastening methods. That is, the lower die is directly fastened to the machine's worktable by four or more high-strength internal hex bolts. Every time the lower die is replaced, the operator must use a special wrench to manually loosen and remove multiple bolts in sequence, then install the new die, and then tighten all the bolts diagonally in sequence. The entire process is not only physically demanding but also time-consuming. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a hydraulic combined punching and shearing machine.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic combined punching and shearing machine, comprising:

[0007] Base;

[0008] A quick-change mold assembly includes a mounting layer fixedly connected to a base, a hydraulic telescopic rod mounted on the mounting layer, an output end of the hydraulic telescopic rod fixedly connected to a mounting frame, a bottom mold body slidably connected to both sides of the mounting layer, a fixed rod slidably connected to the bottom of the bottom mold body, a lifting plate fixedly connected to the bottom of the fixed rod, a transmission block fixedly connected to the bottom of the lifting plate, a transmission rod slidably connected to the transmission block, a pressing rod slidably connected to the top of the bottom mold body, a hook plate fixedly connected to the pressing rod via an inner sliding plate, a second screw cap rotatably connected to the hook plate, a threaded rod threadedly connected to the second screw cap, an internal threaded frame threadedly connected to the threaded rod, and the internal threaded frame fixedly connected to the mounting layer.

[0009] In a preferred embodiment, a transverse groove is provided on the mounting layer, a hook-shaped rod is slidably connected inside the transmission block, a fixing plate is fixedly connected to the hook-shaped rod, the fixing plate is fixedly connected to the mounting layer, a limit rod is fixedly connected to the transmission rod, the limit rod is slidably connected inside the transverse groove, a threaded groove is provided on the transmission rod, and a first screw cap is threadedly connected to the transmission rod.

[0010] The above technical solution is adopted: during use, a transverse groove is opened on the mounting layer to limit the sliding position of the transmission rod. The transverse groove in the mounting layer is opened into a T-shaped groove, in which the limiting rod on the transmission rod slides, and the transmission rod slides in the inclined groove on the transmission block at the same time.

[0011] In a preferred embodiment, a slot adapted to the pressing rod is provided on the top side of the bottom mold body away from the mounting layer, and the bottom of the pressing rod is slidably connected in the slot on the top of the bottom mold body.

[0012] The above technical solution is adopted: when in use, a slot is opened on the bottom mold body to facilitate the insertion of the pressing rod into the slot to fix the bottom mold body. The slot is opened on the side of the bottom mold body away from the installation layer.

[0013] In a preferred embodiment, a circular iron sheet is fixedly connected to the fixing rod, and an opening is provided at the bottom of the bottom mold body for the fixing rod to slide.

[0014] The above technical solution is adopted: When in use, a circular iron plate is fixedly connected to the fixed rod. The circular iron plate slides on the bottom of the bottom mold body. When the operator moves the transmission rod to both sides, it will drive the transmission block to slide up, causing the fixed rod to slide up. The circular iron plate slides on the bottom side of the bottom mold body near the installation layer. In conjunction with the pressing rod, pressure is applied to both ends of the bottom mold body to fix the bottom mold body on the installation layer.

[0015] In a preferred embodiment, the mounting layer has an opening for the inner sliding plate to slide.

[0016] The above technical solution is adopted: during use, an opening is made in the mounting layer to prevent the sliding plate from being blocked.

[0017] In a preferred embodiment, the mounting frame is slidably connected to the pressing rod on the side near the mounting layer.

[0018] Using the above technical solution: When in use, the pressing rod slides on the top of the mounting frame away from the mounting layer.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] This invention utilizes a quick-change structure composed of a transmission rod, transmission block, fixing rod, and hook plate. This eliminates the need for a dedicated wrench to loosen and tighten multiple bolts. Simply move the transmission rod with both hands to slide the fixing rod upwards and clamp the mold. Then, tighten the second cap to secure the other end via the hook plate. This significantly simplifies mold changing operations and reduces repetitive physical labor. It also eliminates the need to tighten multiple bolts with a wrench when changing the lower mold. Operators can securely clamp the lower mold within seconds with simple levering and rotating operations, greatly improving mold changing efficiency, reducing equipment downtime, and lowering the labor intensity and skill requirements for operators. Furthermore, the T-shaped transverse groove of the mounting layer, in conjunction with the limiting rod of the transmission rod, limits the sliding trajectory and ensures the clamping position of the fixing rod. The slot in the bottom mold body facilitates quick insertion and positioning of the pressing rod, and the inner sliding plate opening of the mounting layer prevents parts from jamming, further improving mold changing accuracy and operational smoothness, eliminating the need for repeated mold position adjustments.

[0033] 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.

[0034] like Figures 1 to 6 As shown, this utility model provides a technical solution: a hydraulic combined punching and shearing machine, comprising:

[0035] Base 1;

[0036] The quick-change mold assembly 2 includes a mounting layer 21 fixedly connected to the base 1. A hydraulic telescopic rod 3 (model: HSG-125 / 90E-200) is mounted on the mounting layer 21. The output end of the hydraulic telescopic rod 3 is fixedly connected to a mounting frame 31. Both sides of the mounting layer 21 are slidably connected to a bottom mold body 27. A fixing rod 26 is slidably connected to the bottom of the bottom mold body 27. A lifting plate 25 is fixedly connected to the bottom of the fixing rod 26. A transmission block 24 is fixedly connected to the bottom of the lifting plate 25. A transmission rod 23 is slidably connected to the transmission block 24. A pressing rod 28 is slidably connected to the top of the bottom mold body 27. A hook plate 210 is fixedly connected to the pressing rod 28 via an inner sliding plate 29. A second screw cap 212 is rotatably connected to the hook plate 210. A threaded rod 213 is threadedly connected to the second screw cap 212. An inner threaded frame 211 is threadedly connected to the threaded rod 213. The inner threaded frame 211 is fixedly connected to the mounting layer 21.

[0037] like Figures 1 to 7As shown, this utility model, through a quick-change structure composed of a transmission rod 23, a transmission block 24, a fixing rod 26, and a hook plate 210, directly eliminates the need for a special wrench to loosen and tighten multiple bolts. When changing the mold, first insert the new bottom mold body 27 into the opening of the mounting layer 21, so that its top protrusion abuts against the mounting layer 21. Then unscrew the first cap 214 to move it away from the mounting layer 21. Simply move the transmission rod 23 closer together with both hands, causing the transmission block 24 to slide upward under the guidance of the inclined groove, thereby driving the fixing rod 26. The fixed rod 26 slides upward, causing the circular iron block on the fixed rod 26 to press against the bottom of the bottom mold body 27 near the mounting layer 21, thus tightly clamping one side of the bottom mold body 27. Then, the second screw cap 212 is turned, causing it to drive the threaded rod 213 to rotate and slide down within the inner thread frame 211. This causes the hook plate 210 to drive the inner slide plate 29 to slide down. The inner slide plate 29 further drives the pressing rod 28 to slide down, so that the pressing rod 28 presses against the end of the bottom mold body 27 away from the mounting layer 21, locking it onto the mounting layer 21. Finally, the first screw cap is turned. The cover 214 is secured near the mounting layer 21 and clipped onto the transmission block 24, significantly simplifying the mold-changing operation and reducing repetitive physical labor. Simultaneously, the circular iron block on the fixing rod 26 pushes upwards from the bottom of the bottom mold body 27 near the mounting layer 21, while the hook plate 210, via the inner sliding plate 29 and the pressing rod 28, presses downwards from the top of the bottom mold body 27 away from the mounting layer 21, forming a bidirectional synchronous clamping. This ensures a fixation stability no less than traditional bolt tightening, while significantly shortening mold-changing time and reducing labor costs through a two- or three-step operation process. The equipment downtime waiting time is reduced. In addition, the T-shaped transverse groove 22 of the mounting layer 21 and the limiting rod 42 of the transmission rod 23 can limit the sliding trajectory of the transmission rod 23, ensuring the precise clamping position of the fixing rod 26. The slot of the bottom mold body 27 facilitates the quick insertion and positioning of the pressing rod 28. The opening of the inner slide plate 29 of the mounting layer 21 avoids component jamming, further improving the mold changing accuracy and operation smoothness. There is no need to repeatedly adjust the position of the bottom mold body 27 (the punch has been fixed to the mounting frame 31 with bolts beforehand, taking into account the reliability of the punch fixation).

[0038] Furthermore, an I-shaped block is installed at the bottom of the bottom mold body 27, and through holes for the I-shaped block to slide are opened on both sides of the mounting layer 21.

[0039] like Figures 1 to 2As shown, a transverse groove 22 is provided on the mounting layer 21. A hook-shaped rod 4 is slidably connected inside the transmission block 24. A fixing plate 43 is fixedly connected to the hook-shaped rod 4 and fixedly connected to the mounting layer 21. A limit rod 42 is fixedly connected to the transmission rod 23 and slidably connected inside the transverse groove 22. A threaded groove is provided on the transmission rod 23 and a first screw cap 214 is threadedly connected to the transmission rod 23. In use, the sliding position of the transmission rod 23 is limited by the transverse groove 22 provided on the mounting layer 21. The transverse groove 22 in the mounting layer 21 is a T-shaped groove in which the limit rod 42 on the transmission rod 23 slides. At the same time, the transmission rod 23 slides in the inclined groove on the transmission block 24.

[0040] like Figures 3 to 6 As shown, a slot adapted to the pressing rod 28 is provided on the top of the bottom mold body 27 on the side away from the mounting layer 21. The bottom of the pressing rod 28 is slidably connected in the slot on the top of the bottom mold body 27. In use, the slot on the bottom mold body 27 facilitates the insertion of the pressing rod 28 into the slot to fix the bottom mold body 27. The slot is provided on the side of the bottom mold body 27 away from the mounting layer 21.

[0041] like Figures 4 to 5 As shown, a circular iron plate is fixedly connected to the fixing rod 26. The bottom of the bottom mold body 27 has an opening for the fixing rod 26 to slide. In use, a circular iron plate is fixedly connected to the fixing rod 26. The circular iron plate slides on the bottom of the bottom mold body 27. When the operator moves the transmission rod 23 to both sides, it will drive the transmission block 24 to slide up, causing the fixing rod 26 to slide up. The circular iron plate slides on the bottom side of the bottom mold body 27 near the mounting layer 21. With the help of the pressing rod 28, pressure is applied to both ends of the bottom mold body 27 to fix the bottom mold body 27 on the mounting layer 21.

[0042] like Figures 1 to 3 As shown, the mounting layer 21 has an opening for the inner slide plate 29 to slide. During use, the opening in the mounting layer 21 prevents the slide plate from being blocked.

[0043] like Figures 1 to 3 As shown, the mounting frame 31 is slidably connected to the pressing rod 28 on the side near the mounting layer 21. In use, the pressing rod 28 slides on the top of the mounting frame 31 away from the mounting layer 21.

[0044] Working principle:

[0045] like Figure 1-7As shown, the mounting layer 21 has an opening for the bottom mold body 27 to pass through. When changing the mold, the new bottom mold body 27 is inserted into the mounting layer 21. The protruding part of the bottom mold body 27 abuts against the mounting layer 21. The operator unscrews the first screw cap 214 to move it away from the mounting layer 21. The operator moves the transmission rod 23 closer to each other with both hands, causing the transmission block 24 to slide upward under the guidance of the inclined groove. The transmission block 24 causes the fixed rod 26 to slide upward, causing the round iron block on the fixed rod 26 to abut against the bottom of the bottom mold body 27 near the mounting layer 21, so that it is tightly against the mounting layer 21.

[0046] The operator turns the second screw cap 212, causing the second screw cap 212 to drive the threaded rod 213 to rotate and slide down in the inner threaded frame 211, causing the hook plate 210 to drive the inner slide plate 29 to slide down, causing the inner slide plate 29 to drive the pressing rod 28 to slide down, so that the pressing rod 28 slides down and abuts against the end of the bottom mold body 27 away from the mounting layer 21, locking the end of the bottom mold body 27 away from the mounting layer 21 onto the mounting layer 21, completing the replacement. Turning the first screw cap 214 closer to the mounting layer 21, the first screw cap 214 is locked onto the transmission block 24, completing the fixation.

[0047] Prior to this, the operator fixed the punch (upper die) to the mounting frame 31 with bolts. At this time, the lower die was not installed, and there was a large operating space.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
