Description

Technical Field

[0001] This invention relates to the field of mold ejection technology, specifically to a quick positioning ejection device for a hydroforming mold. Background Technology

[0002] Hydraulic expansion molding refers to a forming method in which hollow parts or tubular materials expand from the inside out through a mold using liquids such as water, emulsion, or oil as the force transmission medium, in a frictionless state. It is widely used in the processing and forming of metal pipes, thermos bottles, and utensils, and is also commonly known as soft mold expansion molding.

[0003] However, this forming method relies on manual loading and unloading of materials, which is highly dangerous. When unloading large forming pipes, there are many pick-up points, and the material may get stuck in the forming channel of the mold base. In such cases, manual intervention is required, with the part positioned between the molds to retrieve the material. For example, small T-shaped copper pipes used in air conditioners and refrigerators have low hardness and are easily stuck in the forming channel of the lower mold base during the water-expansion forming process. During unloading, workers need to insert a steel rod into one end of the copper pipe to pry it out. However, if the T-shaped copper pipe is stuck too tightly, the force applied to the pipe opening by the worker using the steel rod will also increase accordingly, leading to deformation of the pipe opening and resulting in defective products. Furthermore, the process of prying out the T-shaped copper pipe with a steel rod is time-consuming, and the worker is positioned between the upper and lower mold bases, posing a significant safety hazard. Summary of the Invention

[0004] To address the aforementioned issues, a rapid positioning and ejection device for water-expanding molding dies is provided. This device not only automatically feeds T-shaped copper pipes without damaging the pipe openings, but also solves the technical problems of long feeding times, significant safety hazards, and easy damage to pipe openings in existing technologies.

[0005] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0006] A rapid positioning and unloading device for a water-expanding forming mold includes a coordinate robot and a clamping module fixedly installed at the output end of the coordinate robot via a connecting seat. Multiple clamping modules are arranged in a triangular vertical configuration directly below the connecting seat. Three clamping modules correspond one-to-one with the three ends of a T-tube formed in the forming channel of the lower mold base. All three clamping modules are synchronously driven by a synchronous driver vertically positioned in the middle of the connecting seat to synchronously clamp each end of the T-tube. Each clamping module also has a clamping element elastically provided at its end, which can adaptively embed into the end of the T-tube under the drive of the synchronous driver.

[0007] Preferably, the clamping module has a rotating part, which is vertically fixed on the lower surface of the connecting seat, and a telescopic component is coaxially fixed at the lower end of the rotating part; the clamping member is coaxially elastically disposed at the lower end of the telescopic component.

[0008] Preferably, the rotating part includes a fixed hinge seat and a movable hinge column; the fixed hinge seat is vertically fixedly disposed directly below the connecting seat and directly above one end of the tee pipe; the movable hinge column is vertically hinged directly below the fixed hinge seat; in the non-driving state, the fixed hinge seat and the movable hinge column are coaxially arranged.

[0009] Preferably, the telescopic component includes a fixed sleeve and an adjusting stud; the fixed sleeve is coaxially fixedly disposed directly below the movable hinge column; the adjusting stud is coaxially screwed inside the fixed sleeve and disposed near the bottom of the fixed sleeve.

[0010] Preferably, the clamping component includes a spherical clamp and a telescopic column vertically disposed on the outer wall of the spherical clamp; the top end of the telescopic column is also coaxially provided with a first flange, the diameter of the first flange being larger than the diameter of the telescopic column; a first spring is coaxially sleeved and installed on the outside of the telescopic column, and the spherical clamp is coaxially and telescopically disposed at the end of the telescopic assembly and is elastically and telescopically disposed at the end of the telescopic assembly.

[0011] Preferably, the synchronous driver includes a first guide rod, and two sets of the first guide rod are arranged vertically opposite each other directly below the connecting seat; a longitudinal drive block is arranged across the two sets of first guide rods and is slidably connected to the two sets of first guide rods; a screw is also longitudinally screwed to the middle of the longitudinal drive block, and the driving end of the screw is fixedly connected to a servo motor that is vertically fixed on the connecting seat; hinges are also provided on the three sides of the three adjacent clamping modules of the longitudinal drive block and are hinged to the side walls of the adjacent clamping modules through connecting rods.

[0012] Preferably, the synchronous driver is also vertically provided with an elastic clamping module; the elastic clamping module is retractably provided directly below the synchronous driver; the clamping block has one clamping block, which rises and falls synchronously with the longitudinal drive block.

[0013] Preferably, the elastic clamping module includes two sets of second guide rods, which are vertically arranged below the longitudinal drive block. The rods of the two sets of second guide rods pass through the longitudinal drive block and slide in cooperation with it. The clamping block is horizontally arranged between the two sets of second guide rods and located directly below them. The lower surface of the clamping block is also provided with a limit slot for clamping the tee pipe. The top of each second guide rod is also coaxially fixed with a second flange. A second spring is coaxially sleeved and installed outside the second guide rod, with its two ends abutting against the adjacent sides of the longitudinal drive block and the clamping block, respectively.

[0014] Preferably, the limiting slot consists of two sets of V-shaped grooves that are T-shaped and extend to the lower surface of the compression block.

[0015] Preferably, a pressure sensor is also embedded in the lower surface of the compression block. Three sets of pressure sensors are arranged in a triangular configuration on the lower surface of the compression block, avoiding the setting of a limiting slot.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention uses a synchronous driver to synchronously drive three sets of clamping modules to retract, achieving synchronous clamping and unloading of the T-shaped pipe. Simultaneously, the clamping components compensate for any offset in the clamping point when the clamping points deviate during synchronous retraction, significantly improving clamping accuracy and ensuring stable unloading of the T-shaped pipe.

[0018] 2. This invention uses an elastic clamping module that can move synchronously with the longitudinal drive block to continuously clamp the T-shaped pipe before clamping. This achieves the limitation and clamping of the T-shaped pipe before loading or unloading, regardless of whether it is loaded or unloaded, avoiding deviation or other phenomena during the end clamping process, which would lead to clamping failure. This effectively ensures the stability of the T-shaped pipe before clamping. Attached Figure Description

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] See Figures 1 to 8 As shown:

[0037] A rapid positioning and unloading device for a water-expanding molding die includes a coordinate robot 3 and a clamping module 4 fixedly installed at the output end of the coordinate robot 3 via a connecting seat 2. Multiple sets of clamping modules 4 are arranged vertically in a triangular shape directly below the connecting seat 2. Each of the three sets of clamping modules 4 corresponds one-to-one with the three ends of the three-way pipe 1 formed within the forming channel 71 of the lower mold base 7. All three sets of clamping modules 4 are synchronously driven by a synchronous driver 5 vertically positioned in the middle of the connecting seat 2 to synchronously clamp each end of the three-way pipe 1. The ends of the clamping modules 4 are also elastically provided with clamping members 43, which can adaptively embed into the ends of the three-way pipe 1 under the drive of the synchronous driver 5.

[0038] In operation, when it is necessary to unload the T-shaped pipe 1 formed by water expansion from the lower mold base 7, the operator first connects an external power supply to drive the coordinate robot 3. The coordinate robot 3 is a dual-coordinate robot 3 used to drive the unloading device to move horizontally towards the upper mold base 7, and to drive the unloading device to move vertically downward and upward after it is moved onto the upper mold base 7. The coordinate robot 3 is existing technology and will not be described in detail here; it is only shown in the figure. When it is necessary to unload the formed T-shaped pipe 1, the unloading device first moves horizontally to directly above the lower mold base 7 under the drive of the coordinate robot 3. The three sets of clamping modules 4 then expand radially outward under the drive of the synchronous driver 5. Then the coordinate robot 3 continues to drive the unloading device to descend to a preset height, and the synchronous driver... 5. The three clamping modules 4 are synchronously contracted again, so that the clamping parts 43 elastically set at the ends of each clamping module 4 are engaged with each end of the three-way tube 1. Since the clamping parts 43 are elastically set at the ends of the clamping modules 4, when the clamping modules 4 are contracted by the synchronous driver 5, the clamping parts 43 will be embedded into the ends of the three-way tube 1 by their own elasticity. Even if there is a slight deviation, the clamping parts 43 can cover the slight deviation under their own elastic force. So that when the three clamping modules 4 are contracted by the synchronous driver 5, the clamping parts 43 set at the ends of each clamping module 4 can be engaged with each end of the three-way tube 1. Finally, when the coordinate robot 3 applies a pulling force to the clamped three-way tube 1, it ensures that the three-way tube 1 can be easily pulled out from the forming channel 71.

[0039] See Figure 2 As shown:

[0040] The clamping module 4 has a rotating part 41, which is vertically fixed on the lower surface of the connecting seat 2. The lower end of the rotating part 41 is also coaxially fixed with a telescopic component 42; the clamping member 43 is coaxially elastically disposed at the lower end of the telescopic component 42.

[0041] In the working state, the rotating part 41 and the telescopic component 42 are respectively used to provide the clamping member 43 with the freedom to swing back and forth along the long side of the forming channel 71 and to provide the clamping member 43 with the freedom to extend and retract longitudinally, thereby ensuring that the telescopic component 42 can swing back and forth along the long side of the forming channel 71 under the drive of the synchronous driver 5, and the clamping member 43 can be adjusted longitudinally by the telescopic component 42 according to the usage requirements.

[0042] See Figure 3 As shown:

[0043] The rotating part 41 includes a fixed hinge seat 411 and a movable hinge column 412; the fixed hinge seat 411 is vertically fixedly disposed directly below the connecting seat 2 and directly above one end of the three-way pipe 1; the movable hinge column 412 is vertically hinged directly below the fixed hinge seat 411; in the non-driving state, the fixed hinge seat 411 and the movable hinge column 412 are coaxially disposed.

[0044] In the working state, the cooperation between the fixed hinge seat 411 and the movable hinge column 412 provides the telescopic component 42 with the freedom to swing back and forth along the long side of the current forming channel 71, and makes the telescopic component 42 only able to swing back and forth along the long side of the current forming channel 71 without axial rotation; thereby ensuring the stable clamping of the clamping component 43 in the clamping state.

[0045] See Figure 3 As shown:

[0046] The telescopic assembly 42 includes a fixed sleeve 421 and an adjusting stud 422; the fixed sleeve 421 is coaxially fixedly disposed directly below the movable hinge column 412; the adjusting stud 422 is coaxially screwed inside the fixed sleeve 421 and disposed near the bottom of the fixed sleeve 421.

[0047] In operation, the lower end of the adjusting stud 422 has a first channel and a second channel opened sequentially from bottom to top. The diameter of the second channel is larger than that of the first channel, which are used to accommodate the telescopic column 432 and the first flange 433, respectively. The adjusting stud 422, which is coaxially screwed into the fixed sleeve column 421, enables the self-adjustment of the height of the clamping member 43, thereby enabling micro-adjustment of the distance between the clamping member 43 and the inner wall of the forming channel 71, and enabling faster positioning of the clamping point of the three-way pipe 1. When calibrating the clamping point of the three-way pipe 1, the operator only needs to drive the coordinate robot 3 to drive the pushing device to move directly above the three-way pipe 1, and drive the unloading device to descend to a safe height and stop. Then, the operator can manually lower the adjusting stud 422 to perform micro-calibration of the clamping point. The specific calibration method can be determined by the user according to the actual situation. The axial displacement adjustment method of the adjusting stud 422 is not limited to the thread adjustment method, but only aims to make the adjusting stud 422 axially adjustable.

[0048] See Figure 7 and Figure 8 As shown:

[0049] The clamping member 43 includes a spherical clamp 431 and a telescopic column 432 vertically disposed on the outer wall of the spherical clamp 431; the top end of the telescopic column 432 is also coaxially provided with a first flange 433, the diameter of the first flange 433 being larger than the diameter of the telescopic column 432; a first spring 434 is coaxially sleeved and installed on the outside of the telescopic column 432, and the spherical clamp 431 is coaxially and telescopically disposed on the end of the telescopic assembly 42 and is elastically and telescopically disposed on the end of the telescopic assembly 42.

[0050] In operation, when it is necessary to remove the T-shaped pipe 1 formed in the lower mold base 7, the three sets of clamping modules 4 will move vertically towards the T-shaped end extruded in the forming channel 71 of the lower mold base under the drive of the coordinate robot 3. To prevent the three sets of clamping modules 4 from pressing against the inner wall of the forming channel 71 during descent and causing damage, the gap between the front end of the three sets of clamping modules 4 and the inner wall of the forming channel 71 must be at least higher than the wall thickness of the T-shaped pipe 1 when the coordinate robot 3 drives the three sets of clamping modules 4 to descend. This avoids contact between the three sets of clamping modules 4 and the inner wall of the forming channel 71. This places high demands on the driving accuracy of the coordinate robot 3. Once the far end of the three sets of clamping modules 4 and the inner wall of the forming channel 71 are in contact, the gap will be significantly reduced. When the spacing between the forming channels 71 is too large, the clamping end of the clamping module 4 cannot apply effective support to the end of the tee pipe 1. In this case, the spherical clip 431, which is spherically set and retractable at the end of the telescopic component 42, can slide into the port of the tee pipe 1 using its spherical outer wall during the retraction process driven by the synchronous driver 5 when the spacing is too large. It will slide into the port of the tee pipe 1 under the extrusion pressure and can retract on its own under the elastic force of the first spring 434 after clamping. When clamping pipes of different diameters, the work only needs to be done by replacing the spherical clip 431 with one that is compatible with the inner diameter of the current tee pipe 1.

[0051] See Figure 4 As shown:

[0052] The synchronous driver 5 includes a first guide rod 51, of which two sets are provided. The two sets of first guide rods 51 are vertically positioned opposite each other directly below the connecting seat 2. A longitudinal drive block 52 is horizontally positioned between the two sets of first guide rods 51 and is slidably connected to the two sets of first guide rods 51. A screw 54 is also longitudinally screwed to the middle of the longitudinal drive block 52. The driving end of the screw 54 is fixedly connected to a servo motor 55 that is vertically fixed on the connecting seat 2. Hinges 53 are provided on the three sides of the three adjacent clamping modules 4 of the longitudinal drive block 52 and are hinged to the side walls of the adjacent clamping modules 4 through connecting rods 56.

[0053] In operation, the length of the connecting rod 56 changes according to the distance between the clamping module 4 and the adjacent side of the longitudinal drive block 52. When it is necessary to drive the three sets of clamping modules 4 to expand or contract synchronously, it is only necessary to connect an external power supply to drive the servo motor 55 to work. The output shaft of the servo motor 55 rotates synchronously to drive the screw 54 to rotate, thereby driving the longitudinal drive rod to slide back and forth along the axial distance of the first guide rod 51. When the longitudinal drive block 52 moves longitudinally downward under the drive of the screw 54, it synchronously pushes the three sets of clamping modules 4 outward under the action of the connecting rod 56 to achieve the effect of expansion and release. Similarly, when the longitudinal drive block 52 moves longitudinally upward under the drive of the screw 54, it synchronously pulls the three sets of clamping modules 4 inward under the action of the connecting rod 56 to achieve the effect of contraction and clamping.

[0054] See Figure 1 and Figure 5 As shown:

[0055] The synchronous driver 5 is also vertically provided with an elastic clamping module 6; the elastic clamping module 6 is retractably provided directly below the synchronous driver 5; the clamping block 64 has one clamping block 64, which rises and falls synchronously with the longitudinal drive block 52.

[0056] In operation, the clamping block 64 is used to correct and clamp the T-tube 1 during the unloading process, so as to avoid misalignment and displacement of the T-tube 1 caused by the pressure of the clamping module 4 during the clamping process, which would lead to the failure of clamping and unloading. The elastic clamping module 6 can also perform clamping and correction work on the T-tube 1 transmitted on the transmission line and without any displacement when the operator uses the unloading device to load the T-tube 1, thereby preventing the T-tube 1 from moving on its own or being displaced due to vibration or other unexpected situations.

[0057] See Figure 5 and Figure 6 As shown:

[0058] The elastic compression module 6 includes two sets of second guide rods 61, which are vertically arranged below the longitudinal drive block 52. The rods of the two sets of second guide rods 61 pass through the longitudinal drive block 52 and slide in cooperation with it. The compression block 64 is horizontally arranged between the two sets of second guide rods 61 and located directly below them. The lower surface of the compression block 64 is also provided with a limit slot 641 for securing the tee pipe 1. The top of each second guide rod 61 is also coaxially fixed with a second flange 62. The second spring 63 is coaxially sleeved on the outside of the second guide rod 61, and the two ends of the second spring 63 are respectively connected to the adjacent sides of the longitudinal drive block 52 and the compression block 64.

[0059] In the working state, the clamping block 64 is always clamped below the lowest end of the clamping module 4 under the elastic force of the second spring 63. At this time, the unloading device can clamp onto the three-way pipe 1 immediately, whether clamping the unloading or the loading. This ensures the stability of the three-way pipe 1 before clamping. The second flange 62 is used to prevent the clamping block 64 from detaching from the longitudinal drive block 52.

[0060] See Figure 5 and Figure 6 As shown:

[0061] The limiting slot 641 consists of two sets of V-shaped slots 642 that are T-shaped and extend to the lower surface of the pressure block 64.

[0062] In the working state, the two sets of T-shaped V-shaped grooves 642 are set at the junction of the tee pipe 1 to correct and fix the tee pipe 1. The V-shaped grooves can be used for tee pipes 1 of different diameters.

[0063] See Figure 5 As shown:

[0064] The lower surface of the compression block 64 is also embedded with a pressure sensor 65. There are three sets of pressure sensors 65, which are arranged in a triangular manner on the lower surface of the compression block 64 and avoid the limiting slot 641.

[0065] In operation, the three sets of pressure sensors are used to detect whether the pressure block 64 is completely attached to the surface of the platform or the lower mold base 7 under pressure. The three sets of pressure sensors 65 perform real-time detection. When the values ​​of the three sets of pressure sensors 65 are consistent and increase synchronously, it means that the pressure block 64 is being pressed down normally. The synchronous driver 5 then works to synchronously drive the three sets of clamping modules 4 to clamp the T-tube 1. If the vertical values ​​generated by the three sets of pressure sensors 65 are inconsistent or the deviation between the values ​​is large, it means that the pressure is abnormal, and an alarm is issued to remind the staff to handle it.

[0066] This application not only enables efficient and damage-free unloading of T-shaped pipes, but also allows for rapid positioning and loading of T-shaped pipes; the unloading speed is fast and there are no defects.

[0067] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
