Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of U-ring manufacturing technology, and more specifically, to a punch press for processing U-ring fittings. Background Technology

[0002] U-rings are components shaped like the letter "U". They are divided into power-related (metallic material, load-bearing and corrosion-resistant, used for connecting insulators or conductors in high-voltage lines) and daily or industrial (various materials, used as connectors, fasteners or hooks, easy to install), adapting to different scenarios.

[0003] When operators process U-ring fittings, punch presses are often used for punching operations. Although existing punch presses have the basic punching function for U-ring fittings, in actual processing, the U-ring needs to have pin holes punched symmetrically at the ends of its two arms. Although the punch press is equipped with two punching heads, the distance between the two punching heads is fixed, so it can only adapt to the punching requirements of a single specification of U-ring and cannot meet the processing requirements of different specifications of U-rings. This greatly reduces the versatility of the punch press and makes it difficult to adapt to diverse production scenarios. Therefore, it needs to be improved. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a punch press for processing U-shaped ring fittings, which solves the technical problem in the related art that it cannot adapt to diverse production scenarios.

[0005] According to one aspect, at least one embodiment of this disclosure provides a punch press for processing U-shaped ring fittings, including a worktable, a gantry frame fixedly connected to the rear of the top of the worktable, a servo motor fixedly mounted on the top of the back of the gantry frame, a rotating shaft fixedly sleeved at the other end of the output shaft of the servo motor, a long rod fixedly sleeved on the outer surface of the rotating shaft, two movable rods hinged to both ends of the long rod, and two moving blocks hinged to the other ends of the two movable rods on the left and right sides inside the top of the gantry frame, the outer surfaces of the two moving blocks being movably connected to the interior of the gantry frame.

[0006] As a preferred embodiment of this utility model, both ends of the two moving blocks are fixedly connected to a movable block located inside the gantry frame, and the outer surface of the movable block is movably connected to the interior of the gantry frame.

[0007] As a preferred embodiment of this utility model, a first hydraulic cylinder is fixedly connected to the bottom end of each of the two moving blocks. There are two first hydraulic cylinders, and a housing is fixedly installed at the bottom end of each of the two first hydraulic cylinders. There are two housings, and the two housings are of the same size.

[0008] As a preferred embodiment of this utility model, two stamping heads are movably connected inside the two housings, and the bottom ends of the two stamping heads pass through the two housings and extend to the outside of the bottom ends of the two housings.

[0009] As a preferred embodiment of this utility model, two round rods are movably connected inside the two stamping heads. The other ends of the two round rods pass through the two stamping heads and the two housings in sequence and extend to the outside of the back of the two housings, and their outer surfaces are movably connected to the inside of the two housings.

[0010] As a preferred embodiment of this utility model, two circular blocks are fixedly connected to the other ends of the two circular rods, and the outer surfaces of the two circular blocks are rough.

[0011] As a preferred embodiment of this utility model, springs are movably connected to the outer surfaces of the two circular rods. There are two springs in total. One end of each spring is fixedly connected to the front of the two circular blocks, and the other end of each spring is fixedly connected to the back of the two housings.

[0012] As a preferred technical solution of this utility model, two hydraulic cylinders are fixedly installed at the top of both the left and right sides of the workbench. The number of the two hydraulic cylinders is two. A rectangular block is fixedly installed at the other end of each of the two hydraulic cylinders. The number of the two rectangular blocks is two. A guide block located inside the workbench is fixedly connected to the bottom end of each of the two rectangular blocks. The outer surface of the guide block is movably connected to the inside of the workbench.

[0013] As a preferred embodiment of this utility model, a No. 3 hydraulic cylinder is fixedly installed at the top of the front of the workbench, and a movable block is fixedly connected to the other end of the No. 3 hydraulic cylinder. A limiting block located inside the workbench is fixedly installed at the bottom of the movable block, and the outer surface of the limiting block is movably connected to the interior of the workbench.

[0014] As a preferred embodiment of this utility model, a positioning rod is movably connected to the front of the top of the workbench, and the bottom end of the positioning rod extends into the interior of the workbench and is threadedly connected to the interior of the workbench.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, by setting up a servo motor, a rotating shaft, a long rod, a movable rod, and a moving block, the operator starts the servo motor, which causes the rotating shaft and the long rod to rotate. This causes the long rod to drive the two moving blocks to move the two No. 1 hydraulic cylinders in opposite directions through the two movable rods. At this time, the distance between the two No. 1 hydraulic cylinders will increase, so that the two punch heads can subsequently perform punching operations on U-shaped ring fittings of different specifications. This increases the application range of the punch press and makes it adaptable to diverse production scenarios.

[0016] 2. In this disclosure, by setting up a round rod, round block, and spring, the operator pulls the two round blocks in sequence, which will cause the two round rods to disengage from the inside of the two punch heads in sequence, thereby releasing the fixing effect on the two punch heads in sequence. At this time, the two springs will be in a stretched state in sequence, and then the operator can replace the two punch heads in sequence. This allows the operator to quickly perform punching operations of different specifications on the U-shaped ring fittings in subsequent punching operations, thus bringing convenience to the operator.

[0020] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0021] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0022] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0023] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-6 As shown, a punch press for processing U-shaped ring fittings according to an embodiment of the present disclosure is illustrated. It includes a worktable 1, a gantry 2 fixedly connected to the rear of the top of the worktable 1, a servo motor 3 fixedly mounted on the top of the back of the gantry 2, a rotating shaft 4 fixedly sleeved at the other end of the output shaft of the servo motor 3, a long rod 5 fixedly sleeved on the outer surface of the rotating shaft 4, and two movable rods 6 hinged to both the front and rear ends of the long rod 5. The other ends of the two movable rods 6 are hinged to two moving blocks 7 located on the left and right sides inside the top of the gantry 2. The outer surfaces of the two moving blocks 7 are movably connected to the interior of the gantry 2.

[0027] The servo motor 3 has excellent self-locking function, which ensures that the rotating shaft 4, the long rod 5 and the two movable rods 6 always remain stable even when the machine is stopped, without displacement or shaking, thus providing a solid foundation for subsequent structural adjustments.

[0028] In some examples, both ends of the two moving blocks 7 are fixedly connected to the movable blocks 8 located inside the gantry 2, and the outer surface of the movable blocks 8 is movably connected to the interior of the gantry 2.

[0029] The design of four moving blocks 8 effectively limits the movement of the two moving blocks 7.

[0030] In some examples, the bottom ends of the two moving blocks 7 are fixedly connected to a No. 1 hydraulic cylinder 9. There are two No. 1 hydraulic cylinders 9. The bottom ends of the two No. 1 hydraulic cylinders 9 are fixedly installed with a housing 10. There are two housings 10, and the two housings 10 are the same size.

[0031] Since the tops of the two housings 10 are fixedly connected to the bottoms of the two hydraulic cylinders 9, when the two hydraulic cylinders 9 are in operation, the two housings 10 will move downwards.

[0032] In some examples, two stamping heads 11 are movably connected inside the two housings 10, and the bottom ends of the two stamping heads 11 pass through the two housings 10 and extend to the outside of the bottom ends of the two housings 10.

[0033] The design of the two stamping heads 11 enables subsequent stamping and punching operations on the U-ring.

[0034] In some examples, two round rods 12 are movably connected inside the two stamping heads 11. The other ends of the two round rods 12 pass through the two stamping heads 11 and the two housings 10 in sequence and extend to the outside of the back of the two housings 10, and the outer surfaces of the two round rods 12 are movably connected to the inside of the two housings 10.

[0035] When the two round rods 12 are located inside the two stamping heads 11, they will have a fixing effect on the two stamping heads 11.

[0036] In some examples, two circular blocks 13 are fixedly connected to the other end of the two circular rods 12, and the outer surfaces of the two circular blocks 13 are rough.

[0037] Because the outer surfaces of the two round blocks 13 are rough, the operator can pull the two round blocks 13 with less effort.

[0038] In some examples, springs 14 are movably connected to the outer surfaces of the two round rods 12. There are two springs 14. One end of each spring 14 is fixedly connected to the front of the two round blocks 13, and the other end of each spring 14 is fixedly connected to the back of the two housings 10.

[0039] The design of the two springs 14 enables them to effectively reset the movement of the two round rods 12.

[0040] In some examples, two hydraulic cylinders 15 are fixedly installed at the top of both sides of the workbench 1. The other end of each of the two hydraulic cylinders 15 is fixedly installed with a rectangular block 16. The bottom end of each of the two rectangular blocks 16 is fixedly connected to a guide block 17 located inside the workbench 1. The outer surface of the guide block 17 is movably connected to the interior of the workbench 1.

[0041] The design of the two guide blocks 17 effectively limits the movement of the two rectangular blocks 16.

[0042] In some examples, a third hydraulic cylinder 18 is fixedly installed at the top of the front of the workbench 1, and a movable block 19 is fixedly connected to the other end of the third hydraulic cylinder 18. A limiting block 20 located inside the workbench 1 is fixedly installed at the bottom of the movable block 19, and the outer surface of the limiting block 20 is movably connected to the inside of the workbench 1.

[0043] Due to the design of the limit block 20, the movement of the movable block 19 can be well guided.

[0044] In some examples, a positioning rod 21 is movably connected to the front of the top of the worktable 1, and the bottom end of the positioning rod 21 extends into the interior of the worktable 1 and is threaded into the interior of the worktable 1.

[0045] Due to the design of the positioning rod 21, the U-shaped ring can be pre-positioned.

[0046] Working principle and usage process of this utility model: First, the operator needs to replace the positioning rod 21 according to the U-shaped ring fitting to be processed. Rotating the positioning rod 21 will disengage its bottom end from the inside of the worktable 1. Then, the operator selects a positioning rod 21 that matches the inner surface of the U-shaped ring fitting and rotates its bottom end back into the worktable 1. At this point, the operator places the inner side of the U-shaped ring against the outer surface of the positioning rod 21. Subsequently, the two hydraulic cylinders 15 and 18 are activated. The operation of the two hydraulic cylinders 15 causes the two rectangular blocks 16 to move towards each other, thereby squeezing the left and right sides of the U-shaped ring. The operation of hydraulic cylinder 18 will press and fix the front of the U-ring, thereby further increasing the stability of the U-ring during subsequent processing. At this time, the operator starts the servo motor 3, which will cause the rotating shaft 4 and the long rod 5 to rotate. This will cause the long rod 5 to move in opposite directions through the two movable rods 6, and the two moving blocks 7 and the two hydraulic cylinders 9, so that the two punch heads 11 can punch U-rings of different specifications. Then, the operator runs the two hydraulic cylinders 9, which will cause the two housings 10 to move downwards, so that the two punch heads 11 can punch U-rings.

[0047] Finally, when the operator needs to perform punching operations of different specifications on the U-ring, the operator pulls the two round blocks 13 in sequence, so that the two round rods 12 will disengage from the inside of the two punch heads 11 in sequence and release the fixing effect on the two punch heads 11 in sequence. At this time, the two springs 14 will be stretched in sequence, and then the operator can replace the two punch heads 11 in sequence. After the replacement is completed, the operator releases the two round blocks 13 in sequence, so that the two springs 14 will move the two round rods 12 into the inside of the two punch heads 11 in sequence due to the restoring effect of the elastic force, thereby completing the fixing effect on the two punch heads 11.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
