A hydraulic shaft is fixedly installed at the output end of the hydraulic press body, and a mounting block is fixedly installed at the bottom end of the hydraulic shaft. A plug-in sleeve is threaded onto the outer wall of the mounting block, and a pressure block is inserted into the bottom end of the plug-in sleeve. The outer diameter of the pressure end portion of the pressure block is larger than the outer diameter of the plug-in sleeve. A locking rod, threaded and rotatable on the plug-in sleeve, is inserted into the pressure block. The stamping head structure and small hydraulic press provided by this utility model allow for the replacement of pressure blocks to utilize different sized pressure ends, depending on the required hydraulic end face size.

Description

Technical Field

[0001] This utility model relates to the field of small hydraulic press technology, specifically to a stamping head structure and a small hydraulic press. Background Technology

[0002] Small hydraulic presses typically refer to hydraulic presses with compact structures, relatively low load-bearing capacity, and suitable for scenarios such as experiments, mold processing, and parts pressing.

[0003] According to patent publication number CN212171404U, published on December 18, 2020, a hydraulic press for processing and recycling waste metal is disclosed, including a hydraulic tank. A hanging device is fixedly installed in the middle of the left side of the hydraulic tank. Rollers are fixedly installed at the bottom of the hydraulic tank. A first power pump is fixedly installed in the lower left corner of the hydraulic tank. A first power rod is movably connected to the right side of the first power pump. A horizontal hydraulic plate is fixedly connected to the other end of the first power rod. A second power pump is fixedly installed in the middle of the top of the hydraulic tank. The bottom of the second power pump is fixedly connected to... The hydraulic tank is equipped with a second power rod, the other end of which is fixedly connected to a vertical hydraulic plate. A die-casting box is fixedly installed at the lower part of the hydraulic tank, and a feeding hopper is fixedly installed above the die-casting box. A feed inlet is fixedly installed on the right side of the feeding hopper. A movable plate is movably connected to the bottom of the die-casting box, and a rack is fixedly installed in the middle of the movable plate. A gear is meshed on the rack, and a motor is fixedly connected in the middle of the gear. A feeding trough is opened in the middle of the bottom surface of the hydraulic tank, and a receiving net is fixedly installed below the feeding trough. A controller is fixedly installed on the front of the hydraulic tank.

[0004] In the prior art, including the aforementioned patent, a first power pump, a movable plate, and gears are used to automatically compress and form scrap metal. Simultaneously, the movement of the movable plate allows the compressed metal to fall automatically, avoiding manual pressing and unloading. This ensures stable and efficient scrap metal recycling, saving time and labor, and improving the rationality and reliability of the device. However, in the use of such common hydraulic presses, depending on the volume being compressed and the object being compressed, different types of extrusion heads often need to be replaced at the extrusion end to perform cutting and extrusion operations of different sizes. It is known that the smaller the extrusion head, the greater the force per unit area under the same hydraulic force. However, replacing the extrusion head is often cumbersome and not convenient for quick replacement. Utility Model Content

[0005] The purpose of this invention is to provide a stamping head structure and a small hydraulic press to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping head structure, including a hydraulic platform and a hydraulic press body fixedly installed thereon, a hydraulic shaft fixedly installed at the output end of the hydraulic press body, an mounting block fixedly installed at the bottom end of the hydraulic shaft, a plug sleeve threaded on the outer wall of the mounting block, a pressure block inserted into the bottom end of the plug sleeve, and the outer diameter of the pressure end of the pressure block is larger than the outer diameter of the plug sleeve, and a locking rod threaded on the plug sleeve is inserted into the pressure block.

[0007] Preferably, the outer wall of the mounting block has cut sections arranged in a circular array, and the multiple through holes on the plug sleeve correspond to the threaded holes on the cut sections.

[0008] Preferably, the bottom end of the pressure block is provided with a cutting plate.

[0009] Preferably, a pad is inserted into the plug sleeve, and the horizontal plates symmetrically arranged on the pad are respectively movably arranged on the notches symmetrically opened on the cutter plate. A main spring is fixedly installed between the cutter plate and the hydraulic table.

[0010] Preferably, when the notch is attached to the hydraulic table, the bottom end of the cutter plate and the bottom surface of the pressure end are on the same horizontal plane.

[0011] Preferably, when the bottom surfaces of the cutter plate and the pressure end are on the same horizontal plane, the positioning hole on the cutter plate is located on the path of the locking rod.

[0012] Preferably, the cutting plate is made of steel plate.

[0013] Preferably, the top surface of the pallet fixedly mounted on the hydraulic platform and the bottom surface of the pressure end are parallel.

[0014] Preferably, the insertion sleeve is a steel sleeve.

[0015] A small hydraulic press includes the stamping head structure described in the above-mentioned solution.

[0016] In the above technical solution, the punch head structure and small hydraulic press provided by this utility model have the following beneficial effects: by using the mounting block as the fixed end, and fixing it by threading the plug sleeve onto the mounting block, the plug sleeve is used as the mounting part for quick insertion of the pressure block. Thus, the pressure block can be replaced to use different sizes of pressure end face as needed according to the required hydraulic end face size. Since the outer diameter of the pressure end face is larger than the outer diameter of the plug sleeve, when the pressure end face is subjected to force, it can directly act on the plug sleeve and transmit the force to the hydraulic shaft. Thus, it can be locked with the locking rod for quick replacement of the pressure block. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution, including the following embodiments:

[0027] Example 1

[0028] Combination Figure 1 , Figure 5 This embodiment aims to solve the problem of inconvenient replacement of the extrusion head at the extrusion end of a traditional hydraulic press during hydraulic operation. Therefore, based on this problem, this embodiment facilitates the quick replacement of extrusion heads of different sizes and types by switching the traditional bolt-mounted extrusion head method.

[0029] Specifically, the hydraulic shaft 21 is fixedly installed on the output end of the hydraulic press body 2 by welding, and then fixed by the mounting block 3. The plug sleeve 4 is threaded onto the mounting block 3 for fixation. The plug sleeve 4 is used as a quick-connect fitting for the pressure block 6. As needed, the pressure block 6 can be replaced with different sized pressure ends 62. Since the outer diameter of the pressure end 62 is larger than the outer diameter of the plug sleeve 4, when the pressure end 62 is under force, it can directly act on the plug sleeve 4 and transmit the force to the hydraulic shaft 21, thereby cooperating with the locking rod 7 to lock and quickly replace the pressure block 6. Furthermore, the plug sleeve 4 is threaded onto the outer wall of the mounting block 3. At this time, the multiple through holes 41 correspond to the threaded holes 32 opened on the cut surface 31, which facilitates the subsequent use of bolts to pass through the multiple through holes 41 and thread them onto the threaded holes 32, thereby preventing the plug sleeve 4 from loosening. The inner wall of the plug sleeve 4 is provided with a sliding groove 42. The protrusion 61 fixedly installed on the pressure block 6 is an integral structure with the pressure block 6. The protrusion 61 slides in the sliding groove 42 to guide and limit the sliding of the pressure block 6.

[0030] Example 2

[0031] Combination Figure 2 As shown, this embodiment describes in detail how, for different hydraulic and cutting needs, a cutting component is added to facilitate more tearing hydraulic cutting, thereby adapting to different cutting needs and other needs such as interference fits and crushing of scrap non-ferrous metals.

[0032] Specifically, the cutting plate 5 is slidably disposed on the pressure block 6 and the pressure end 62, and the bottom end of the cutting plate 5 extends out of the bottom surface of the pressure end 62. By inserting the horizontal plate 81 on the pad 8 into the insertion sleeve 4, the horizontal plate 81 on the pad 8 can block and support the upward sliding of the cutting plate 5 relative to the pressure block 6. Thus, when the pressure end 62 moves downward, the bottom end of the cutting plate 5 is subjected to force to cut the object, so as to meet the needs of different cutting or hydraulic systems.

[0033] Example 3

[0034] Combination Figure 5 As shown, this embodiment aims to solve the problem that some hydraulically manipulated objects deform and become nested on the pressure end 62 during hydraulic operation, making them difficult to detach.

[0035] Specifically, the two ends of the main spring 53 are fixedly installed on the mounting block 3 and the cutting plate 5, respectively. In the default state, the main spring 53 pushes the cutting plate 5 to extend out of the bottom surface of the pressing end 62. At this time, when the pressing end 62 moves down, the bottom end of the cutting plate 5 is subjected to force to cut the object. During the process of being subjected to force, the cutting plate 5 slides up a distance relative to the pressing block 6 and stops under the obstruction of the horizontal plate 81. Then the main spring 53 stores force, which makes it easier for the cutting plate 5 to be removed from the object. When the cutting plate 5 is removed from the object, the main spring 53 releases the stored force and moves down relative to the pressing end 62, thereby pushing the object and reducing the object from getting stuck on the side of the pressing end 62.

[0036] Example 4

[0037] Combination Figure 4 and Figure 5 As shown, this embodiment aims to solve how to store the cutting plate 5 when using hydraulic pressure on the pressure end 62, or how to quickly protrude from the bottom surface of the pressure end 62 when the cutting plate 5 needs to be used for cutting.

[0038] Specifically, the horizontal plate 81 is symmetrically fixedly welded to the pad 8, and the support plate 11 is fixedly welded to the hydraulic table 1. When it is necessary to position the bottom end of the cutter plate 5 and the bottom surface of the pressing end 62 on the same horizontal plane, the horizontal plate 81 on the insertion sleeve 4 is pulled out, and then the hydraulic press body 2 is driven to move the pressing end 62 downward, so that the cutter plate 5 is attached to the top of the support plate 11. Then, when the pressing end 62 is completely attached to the top of the support plate 11, the notch 52 on the cutter plate 5 is attached to the hydraulic table 1. At this time, the positioning hole 51 is located on the path of the locking rod 7. Then, by continuing to rotate the locking rod 7 by thread, the locking rod 7 is inserted into the positioning hole 51. At this time, the main spring 53 deforms and stores force, so that the cutter plate 5 is kept in the state of being housed in the pressure block 6, and the bottom end of the cutter plate 5 and the bottom surface of the pressing end 62 are always on the same horizontal plane, so as to make use of the bottom surface of the pressing end 62 for hydraulic force application. Similarly, when the cutter plate 5 needs to be used again, the locking rod 7 is rotated and disengaged from the positioning hole 51. Then, when the pressure end 62 disengages from the top of the support plate 11, the main spring 53 releases its stored force to push the cutter plate 5, causing the bottom end of the cutter plate 5 to protrude again from the bottom surface of the pressure end 62. Then, the horizontal plate 81 is inserted into the insertion sleeve 4 again, so that during hydraulic operation, the cutter plate 5 remains protruding from the bottom surface of the pressure end 62 for cutting. Thus, through the cooperation of the cutter plate 5, locking rod 7, and horizontal plate 81, it is possible to retract the cutter plate 5 when the pressure end 62 is hydraulically operated, or to quickly protrude from the bottom surface of the pressure end 62 for cutting. This solves the problems of cumbersome traditional bolt installation.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
