[0026] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.
[0027] like Figures 1-9 As shown, a polymer-modified shaped tubular rubber cutting device includes a worktable, on which a shaped tubular molding fixture 1 is detachably mounted. The shaped tubular molding fixture 1 has a molding fixture groove for placing the shaped tubular product 2. A vertically movable blade holder 10 is also mounted on the worktable, on which a cutting blade 9 is mounted. The cutting blade 9 is used to trim the end of the shaped tubular product 2 to be flush. A lower pressure block 6 is also fixedly mounted on the worktable, on which a guide post 7 is fixedly mounted. An upper pressure block 8 is slidably mounted on the guide post 7. Semicircular grooves 81 are opened on opposite sides of the lower pressure block 6 and the upper pressure block 8. Copper sleeve one 13 and copper sleeve two 14 are detachably mounted in the two semicircular grooves 81, respectively. Copper sleeve one 13 and copper sleeve two 14 are identical and arranged in opposite directions. When copper sleeve one 13 and copper sleeve two 14 are closed, they clamp and fix the tubular part of the shaped tubular product 2 that extends out of the molding fixture groove.
[0028] It should be noted that a gantry is installed on the worktable, and the tool holder 10 is movably installed on the gantry. The lower pressure block 6 and the upper pressure block 8 are the same but arranged in opposite directions. The lower pressure block 6 can be fixed to the worktable or movably installed on the worktable. When the lower pressure block 6 is movably installed on the worktable, its guide post 7 is fixedly installed on the worktable surface, and the lower pressure block 6 is movably installed on the guide post 7. The number of guide posts 7 can be set to more than one. In this case, the lower pressure block 6 and the upper pressure block 8 can be driven by a synchronous motor with dual output ends. When the copper sleeve 13 and the copper sleeve 2 14 are closed, they correspond exactly to the slot of the copying fixture. The lower pressure block 6 and the upper pressure block 8 are the same. That is to say, the structure and the installation mechanism set on the upper pressure block 8 are also present in the lower pressure block 6. Therefore, they will not be described in detail.
[0029] In this embodiment, the specific implementation scenario is as follows: the shaped tube product 2 is fixed in the molded jig groove of the shaped tube molded jig 1, and the product is clamped with a quick clamp 3 to prevent the product from shifting. After the product is pre-fixed, simply press the switch button 4, and the material head clamping cylinder 5 clamps the upper pressure block 8 and the lower pressure block 6 through the guide post 7. The copper sleeve 13 on the upper pressure block 8 and the copper sleeve 14 on the lower pressure block 6 come into contact with the product to clamp it. The cutting blade 9 is fixed on the cutter holder 10 and slides on the linear guide rail 11. The cutting cylinder 12 pushes the entire cutter holder 10 downward to cut the end of the product that extends out of the molded jig groove. In this way, the end face of the product is cut. The waste material falls into the waste frame through the waste material drop chute 15. After the entire cycle is completed, the product is taken out. This realizes the semi-automatic cutting process of polymer shaped tubular rubber.
[0030] In one embodiment of this utility model, a quick clamp 3 is provided on one side of the shaped tube molding fixture 1. The quick clamp 3 is used to pre-position the shaped tube product 2 in the molding fixture groove. The quick clamp 3 includes a fixing block, a strip frame is ball-hinged on the fixing block, a strip hole is opened on the strip frame, and a pressure rod is slidably installed in the strip hole. The end of the pressure rod is adapted to the tube wall of the shaped tube product 2.
[0031] It should be noted that when using the quick-release chuck 3, manually move the strip frame so that the position of the pressure rod roughly corresponds to the product in the profile jig groove. Then slide the pressure rod in the strip hole to further adjust its position, so that the end of the pressure rod presses against the tube wall of the shaped tube product 2, achieving the pre-positioning effect. The connection between the fixed block and the ball joint of the strip frame is equipped with damping to improve the pre-positioning effect of the quick-release chuck 3.
[0032] In one embodiment of this utility model, a waste material discharge trough 15 is installed on the workbench, the waste material discharge trough 15 is located below the cutting blade 9, a vertical linear guide rail 11 is installed on the workbench, the blade holder 10 is slidably mounted on the linear guide rail 11, and a feed cylinder 12 is provided at the top of the linear guide rail 11, the output end of the feed cylinder 12 is fixedly connected to the blade holder 10.
[0033] It should be noted that the linear guide 11 is mounted on the gantry, the fixed end of the feed cylinder 12 is also mounted on the gantry, and the output end of the feed cylinder 12 is fixedly connected to the tool holder 10.
[0034] In one embodiment of this utility model, a material head clamping cylinder 5 is also installed on the workbench. The output end of the material head clamping cylinder 5 is fixedly connected to the upper pressing block 8, and the copper sleeve 14 is coaxially arranged with the groove of the molded jig groove.
[0035] It should be noted that the material head clamping cylinder 5 is also fixedly installed on the gantry frame.
[0036] In one embodiment of this utility model, the top of the groove of the upper pressure block 8 is provided with a mating groove, the copper sleeve 13 is integrally formed with a top block 131, the top block 131 is adapted to the mating groove, the outer side of the copper sleeve 13 is provided with a slot 132, and both sides of the upper pressure block 8 are provided with a transverse hole 82 that penetrates into the semi-circular groove 81. A telescopic insertion rod 83 is installed on the transverse hole 82, the insertion rod 83 is adapted to the slot 132, and when the insertion rod 83 is inserted into the slot 132, the copper sleeve 13 is locked in the semi-circular groove 81.
[0037] It should be noted that the top block 131 can be rectangular, inverted triangular, or have a toothed edge, mainly to facilitate the installation of the copper sleeve into the semi-circular groove 81, enabling quick installation and removal of the copper sleeve. The insertion rod 83 cooperates with the slot 132 to restrict the movement of the copper sleeve along the groove direction.
[0038] In one embodiment of this utility model, a baffle is installed in the middle of the horizontal hole 82, and the insertion rod 83 is movably embedded in the baffle. A wedge block is provided at the end of the insertion rod 83 away from the semicircular groove 81. The inclined surface of the wedge block is located at the end of the wedge block away from the semicircular groove 81. A spring is fitted on the rod wall of the insertion rod 83, and the two ends of the spring are connected to the wedge block and the baffle respectively.
[0039] It should be noted that when a force is applied to the inclined surface of the wedge block along the length of the copper sleeve, the wedge block moves along the rod direction of the insertion rod 83, compressing the spring, and the insertion rod 83 is inserted into the slot 132.
[0040] In one embodiment of this utility model, both sides of the upper pressing block 8 are provided with sliding grooves 84 along the width direction. The sliding grooves 84 are connected to the transverse holes 82. Both sides of the upper pressing block 8 are provided with disassembly and assembly mechanisms 16. The disassembly and assembly mechanism 16 includes a slider 161, a tension spring 162, a limiting rod 163 and a limiting groove. The slider 161 is slidably disposed on the sliding groove 84. A limiting groove is provided on the side of the slider 161 away from the upper pressing block 8. One end of the tension spring 162 is hooked to the upper pressing block 8, and the other end of the tension spring 162 is connected to the slider 161. The limiting rod 163 has a U-shaped structure. One end of the limiting rod 163 is rotatably disposed on the upper pressing block 8, and the other end of the limiting rod 163 is slidably disposed in the limiting groove.
[0041] In one embodiment of this utility model, the limiting groove includes a first guide groove 164, a second guide groove 165, and a third guide groove 166 connected end to end. The second guide groove 165 has a V-shaped structure. When the limiting rod 163 is slidably disposed in the second guide groove 165, the slider 161 is pulled by the limiting rod 163. At this time, the slider 161 presses the inclined surface of the wedge block near the inner side of the transverse hole 82, so that the insertion rod 83 is inserted into the slot 132. The connection of the first guide groove 164, the second guide groove 165, and the third guide groove 166 is provided with a step to limit the limiting rod 163 to always slide in a clockwise direction in the limiting groove.
[0042] It should be noted that, with Figure 7 The positional relationship is described as follows: When the slider 161 is manually pushed to the right, the limiting rod 163 moves from the right end of the first guide groove 164 to the left end. At this time, the tension spring 162 is stretched. When the left end of the limiting rod 163 passes through the first guide groove 164 and enters the guide groove 165, the slider 161 is released. Under the action of the tension spring 162 returning to its original position, the slider 161 moves to the left. However, at this time, the left end of the limiting rod 163 is located in the recess in the second guide groove 165, locking the position of the slider 161. At this time, the inner side of the slider 161 is exactly pressing against the inclined surface of the wedge block. Insert the insert rod 83 into the slot 132 to complete a locking state of the insert rod 83, and fix the copper sleeve in the semi-circular groove 81. When it is necessary to replace the copper sleeve of other specifications, manually adjust the position of the left end of the limiting rod 163 in the second guide groove 165, so that it slides back to the initial position of the first guide groove 164 along the direction of the second guide groove 165 and the third guide groove 166, release the wedge block squeeze of the slider 161, and let the insert rod 83 return to the slot 132 under the reset action of the spring. At this time, the copper sleeve can be slid out of the semi-circular groove and removed.
[0043] In one embodiment of this utility model, a switch button 4 is installed on the workbench, and the switch button 4 controls the opening and closing of the material head clamping cylinder 5 and the feed cylinder 12 via a PLC.
[0044] It should be noted that the irregularly shaped rubber tube is manually placed into the molding fixture 1, the quick clamp 3 is locked, and the switch button 4 is pressed. After the PLC receives the signal, it will control the material head clamping cylinder 5 to move. After the upper pressure block 8 presses down and clamps the product material head, the sensor on the material head clamping cylinder 5 will send a signal to the PLC. At this time, the cutting cylinder 12 will push the entire cutter holder 10 to slide downward on the linear guide rail 11 until the product is cut. This process is repeated to achieve semi-automatic irregularly shaped tube cutting.
[0045] This device uses semi-automatic control. When the product is placed into the molding fixture, the PLC will send a command to control the clamping cylinder to clamp the upper and lower pressure blocks, ensuring that the part of the product to be cut is fixed in place. At this time, the sensor will send a signal to the PLC. The next step is to control the feed cylinder to push the entire blade holder downward until the blade on the blade holder completely cuts off the end face of the pipe. After cutting, the feed cylinder will immediately retract, and then the clamping cylinder will release the pressure blocks. The product can then be manually removed. Compared with the previous manual positioning and manual cutting, this method greatly saves labor costs, improves cutting efficiency, and ensures quality.
[0046] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
