DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a hydraulic stretching machine workpiece transposition manipulator, such as Figures 1 to 5 As shown, it includes a hydraulic device and mechanical parts. The hydraulic device includes a top plate 1 and a bottom plate 2. The top plate 1 and the bottom plate 2 are fixedly connected by multiple support rods 3, and a lifting plate 4 is arranged between the top plate 1 and the bottom plate 2. A first cylinder 5 is installed on the top surface of the top plate 1. The top surface of the lifting plate 4 is transmission-connected to the output end of the first cylinder 5. An upper die 6 is installed on the bottom surface of the lifting plate 4. A pressing ring 8 is fixedly installed on the top surface of the bottom plate 2 by a vertical rod 7. A second cylinder 9 is installed inside the groove at the center of the top surface of the bottom plate 2. A lower pressing block 10 is installed on the top of the output end of the second cylinder 9. A workpiece plate 11 to be hydraulically pressurized is placed on the top surface of the pressing ring 8. The lower pressing block 10 corresponds to the bottom opening of the upper die 6. The lower pressing block 10 cooperates with the upper die 6 to press the workpiece plate 11, so that the workpiece plate 11 forms a pot workpiece. After the workpiece plate 11 to be hydraulically pressed is placed on the top surface of the pressure ring 8, the first cylinder 5 is started. The output end of the first cylinder 5 causes the lifting plate 4 to move downward. A plurality of support rods 3 correspondingly limit the lifting plate 4. The lifting plate 4 drives the upper die 6 to move vertically and smoothly downward until the bottom surface of the upper die 6 contacts the top surface of the workpiece plate 11. The upper die 6 cooperates with the pressure ring 8 to limit the workpiece plate 11 to be hydraulically pressed. Start the second cylinder 9, and the output end of the second cylinder 9 pushes the lower pressure block 10 to move upward. The lower pressure block 10 moves upward at the center of the pressure ring 8, and the top of the lower pressure block 10 squeezes the workpiece plate 11 until the lower pressure block 10 moves to the bottom opening of the upper die 6. The workpiece plate 11 is deformed inside the bottom opening of the upper die 6. The lower pressure block 10 cooperates with the upper die 6 to form a cookware workpiece inside the bottom opening of the upper die 6. The output end of the first cylinder 5 causes the lifting plate 4 to drive the upper die 6 to move upward, and the second cylinder 9 causes the lower pressure block 10 to move downward, and the cookware workpiece is formed on the top surface of the pressure ring 8.

[0028] The mechanical components include two opposing slides 12, which are fixedly connected by two sets of connecting components. The connecting components adsorb the workpiece plate 11, and one end of the slide 12 is externally connected to the output end of the control cylinder, and the outer side of the slide 12 is transmission-connected to the control component. The control cylinder uses the control component to make the slide 12 move back and forth on the top of the base plate 2, and a third cylinder 13 is installed on the top surface of the base plate 2. The control component is transmission-connected to the output end of the third cylinder 13, and the third cylinder 13 uses the control component to make the slide 12 drive the workpiece plate 11 at the bottom of the connecting component to move up and down. Start the control cylinder, and the output end of the control cylinder uses the slide 12 to drive the mechanical parts to move left, and the slide 12 uses the connecting parts to drive the workpiece plate 11 to move synchronously until the workpiece plate 11 is at the top of the pressure ring 8, and then start the third cylinder 13. The output end of the third cylinder 13 uses the control parts to move the mechanical parts downward, and the downward-moving mechanical parts use the connecting parts at the bottom of the slide 12 to drive the workpiece plate 11 to move downward until the bottom surface of the workpiece plate 11 is in contact with the top surface of the pressure ring 8, and the output end of the control cylinder uses the slide 12 to drive the mechanical parts to continue to move left until the workpiece plate 11 is between the two connecting parts, thereby completing the placement of the workpiece plate 11.

[0029] After the hydraulic pressure of the workpiece plate 11 is completed, the output end of the third cylinder 13 moves the slide 12 upward, and the output end of the control cylinder causes the slide 12 to drive the connecting component to move right. After the connecting component moves to the top of the cookware workpiece, the output end of the third cylinder 13 moves the slide 12 downward, and the slide 12 uses the connecting component to absorb the cookware workpiece on the top surface of the pressure ring 8, and the output end of the control cylinder causes the slide 12 to drive the connecting component and the cookware workpiece to move left, so as to facilitate the removal of the cookware workpiece from the top surface of the pressure ring 8. At this time, the connecting component on the right side replaces the workpiece plate 11 to be hydraulically pressurized on the top surface of the pressure ring 8, so as to facilitate continuous hydraulic processing of multiple workpiece plates 11.

[0030] exist Figure 2 and Figure 3In the embodiment, the connection part includes two parallel inner plates 14, and the centers of the two inner plates 14 are penetrated by a plug rod 15, and the bottom ends of the two plug rods 15 are fixedly connected by a connecting plate, and the surface of the plug rod 15 is sleeved with a first spring 16, and the top end of the first spring 16 is connected to the bottom surface of the inner plate 14, and the bottom end of the first spring 16 is connected to the top surface of the connecting plate, and the surface of the connecting plate is vertically inserted with an air pipe 17, and the bottom end of the air pipe 17 is provided with a sticking ring, and the top end of the air pipe 17 is connected to the air pump by a conduit. Two opposite ring clamps 18 are fixed on the top surface of the connecting plate, and the surfaces of the two ring clamps 18 are sleeved with a rotating sleeve 19, and the rotating sleeve 19 is spirally sleeved on the surface of the air pipe 17. When the rotating sleeve 19 is rotated, the rotating sleeve 19 is limited by the ring clamp 18, and the rotating sleeve 19 is spirally matched with the air pipe 17, so that the air pipe 17 and the sticking ring can be replaced in real time, and the suitable sticking ring can be selected according to the workpiece plate 11 to be hydraulically operated. When the slide 12 drives the connecting component to move downward, the bottom surface of the sticking ring at the bottom end of the air pipe 17 contacts the workpiece plate 11 or the top surface of the cookware workpiece, and the reaction force of the workpiece plate 11 or the cookware workpiece on the sticking ring causes the connecting plate to move up, and the upward moving connecting plate drives the insertion rod 15 to move upward at the center of the inner plate 14, and the connecting plate and the inner plate 14 cooperate to squeeze the first spring 16 on the surface of the insertion rod 15, and the elastic force of the first spring 16 is used to absorb the reaction force of the workpiece plate 11 or the cookware workpiece on the sticking ring, thereby avoiding damage to the sticking ring under the reaction.

[0031] After the bottom surface of the sticking ring contacts the workpiece plate 11 or the cookware workpiece, the air pump uses the conduit to extract the air inside the air pipe 17. At this time, the air pipe 17 uses the sticking ring to absorb the workpiece plate 11 or the cookware workpiece. When the air pump uses the conduit to ventilate the inside of the air pipe 17, the workpiece plate 11 or the cookware workpiece falls from the bottom of the sticking ring.

[0032] exist Figure 1 , Figure 2 and Figure 4 In the embodiment, the control component includes two outer plates 20, and the two outer plates 20 correspond to the two slides 12 one by one. The outer plates 20 are located on the outside of the slide 12, and the two ends of the outer plates 20 are respectively sleeved on the surfaces of the two support rods 3, and the bottom surface of the outer plates 20 is transmission-connected to the output end of the third cylinder 13. An inner block 21 is provided on the inner side surface of the outer plate 20, and a screw is spirally penetrated through the surface of the outer plate 20. The inner block 21 is fixedly installed on the inner side surface of the outer plate 20 by means of the screw, and a slide groove 22 is provided on the outer side surface of the slide 12, and the inner block 21 is inside the slide groove 22, and the slide 12 slides on the surface of the inner block 21 by means of the slide groove 22. Since the outer plate 20 is sleeved on the surface of the support rod 3 under the limitation of the output end of the third cylinder 13, the outer plate 20 uses the inner block 21 to limit the slide 12. When the cylinder output end is controlled to move the slide 12, the moving slide 12 uses the slide groove 22 to move left and right on the surface of the inner block 21. The slide 12 that moves left and right uses the air pipe 17 installed on the inner plate 14 to drive the workpiece plate 11 or the cookware workpiece to move synchronously.

[0033] exist Figure 2 , Figure 5 and Figure 6 In the figure, arc plates 23 are arranged on both sides of the pressure ring 8, and the two arc plates 23 are arranged opposite to each other. The inner concave surface of the arc plate 23 fits with the outer side surface of the circumference of the pressure ring 8, and the top surface of the arc plate 23 is chamfered. A ring 24 is fixed to the bottom of the inner concave surface of the arc plate 23, and the ring 24 is sleeved on the surface of the vertical rod 7. A second spring 25 is sleeved on the surface of the vertical rod 7. The top end of the second spring 25 is connected to the bottom surface of the ring 24, and the bottom end of the second spring 25 is connected to the top surface of the bottom plate 2. A screw sleeve is arranged on the top surface of the ring 24, and the screw sleeve is spirally sleeved on the surface of the vertical rod 7. When the air pipe 17 uses the sticking ring to place the adsorbed workpiece plate 11 on the top of the pressure ring 8, the side of the workpiece plate 11 will contact the chamfered part of the arc plate 23 during the downward movement, and the workpiece plate 11 exerts pressure on the arc plate 23 through the chamfered part to make the arc plate 23 move downward, and the downwardly moved arc plate 23 uses the sleeve ring 24 to move downward on the surface of the vertical rod 7, and the downwardly moved sleeve ring 24 cooperates with the second spring 25 that squeezes the surface of the vertical rod 7. At this time, the output end of the cylinder is controlled to move the slide 12, so that the workpiece plate 11 corresponds to the top of the pressure ring 8, and the elastic force of the second spring 25 rebounds. At this time, the sleeve ring 24 drives the arc plate 23 to move upward, so that the workpiece plate 11 can be placed on the top surface of the pressure ring 8.

[0034] exist Figures 5 to 7In the embodiment, a side plate 26 is fixed to the top of the outer convex surface of the arc plate 23, and the top surface of the side plate 26 is flush with the top surface of the arc plate 23. A through groove is provided on the surface of the side plate 26, and an inner rod 27 is inserted into the through groove. A limiting plate 28 is connected to the top of the inner rod 27, and a push plate 29 is connected to the bottom of the inner rod 27. A spring piece 30 is provided inside the through groove, and one end of the spring piece 30 is in contact with the surface of the inner rod 27. The top surface of the push plate 29 is connected to the bottom surface of the side plate 26 by an elastic strip 31, and the elastic strip 31 is made of rubber material. A rotating plate 32 is rotatably connected at the center of the arc plate 23, and the bottom end of the rotating plate 32 is located on the inner side of the arc plate 23. The top end of the rotating plate 32 is rotatably connected to the inner side of the arc plate 23. A side plate 33 is fixed to the inner side of the push plate 29, and the inner end of the side plate 33 is hinged to the bottom end of the rotating plate 32, and the side plate 33 is arranged horizontally. The workpiece plate 11 moves downward between the two arc-shaped plates 23. When the side edge of the workpiece plate 11 moves downward and contacts the top surface of the rotating plate 32, the workpiece plate 11 squeezes the rotating plate 32 to cause the rotating plate 32 to rotate. Since the top of the rotating plate 32 is rotated and clamped on the inner side of the arc-shaped plate 23, the bottom end of the rotating rotating plate 32 drives the push plate 29 to move downward using the side plate 33. In the process of moving downward, the push plate 29 gradually moves away from the arc-shaped plate 23. The moving push plate 29 cooperates with the pulling of the elastic strip 31, and the elastic strip 31 is pulled downward. The push plate 29 31 is deformed and lengthened, and gradually moves away from the arc plate 23, driving the inner rod 27 to squeeze the spring piece 30 on the inner side of the through groove until the bottom end of the rotating plate 32 rotates to the inside of the arc plate 23. At this time, the workpiece plate 11 continues to move downward until the workpiece plate 11 is separated from the rotating plate 32. The elastic force of the elastic strip 31 and the spring piece 30 causes the push plate 29 to move upward and close to the arc plate 23. The push plate 29 uses the side plate 33 to make the bottom end of the rotating plate 32 rotate to the top of the workpiece plate 11 again.

[0035] The workpiece plate 11 is placed on the top surface of the pressure ring 8, and the screw sleeve is screwed, and the screw sleeve moves downward on the surface of the vertical rod 7. The downwardly moved screw sleeve uses the collar 24 to drive the arc plate 23 and the rotating plate 32 to move downward until the bottom end of the rotating plate 32 corresponds to the top surface of the workpiece plate 11, so that workpiece plates 11 of different thicknesses can be placed on the top of the pressure ring 8. At this time, the bottom end of the rotating plate 32 does not contact the top surface of the workpiece plate 11, and the two opposite arc plates 23 place the workpiece plate 11 on the top surface of the pressure ring 8, and the two opposite rotating plates 32 prevent the workpiece plate 11 from tilting on the top surface of the pressure ring 8, and the upper die 6 that squeezes the workpiece plate 11 does not contact the rotating plate 32.

[0036] Working principle of the present invention:

[0037] Reference Figures 1 to 7As shown, the control cylinder is started, and the output end of the control cylinder uses the slide 12 to drive the mechanical parts to move left, and the slide 12 uses the connecting parts to drive the workpiece plate 11 to move synchronously until the workpiece plate 11 is at the top of the pressure ring 8, and then the third cylinder 13 is started, and the output end of the third cylinder 13 uses the control parts to move the mechanical parts downward, and the downward-moving mechanical parts use the connecting parts at the bottom of the slide 12 to drive the workpiece plate 11 to move downward until the bottom surface of the workpiece plate 11 is in contact with the top surface of the pressure ring 8, and the output end of the control cylinder uses the slide 12 to drive the mechanical parts to continue to move left until the workpiece plate 11 is between the two connecting parts, thereby completing the placement of the workpiece plate 11.

[0038] When the slide 12 drives the connecting component to move downward, the bottom surface of the sticking ring at the bottom end of the air pipe 17 contacts the workpiece plate 11 or the top surface of the cookware workpiece, and the reaction force of the workpiece plate 11 or the cookware workpiece on the sticking ring causes the connecting plate to move up, and the upward moving connecting plate drives the insertion rod 15 to move upward at the center of the inner plate 14, and the connecting plate and the inner plate 14 cooperate to squeeze the first spring 16 on the surface of the insertion rod 15, and the elastic force of the first spring 16 is used to absorb the reaction force of the workpiece plate 11 or the cookware workpiece on the sticking ring, thereby avoiding damage to the sticking ring under the reaction.

[0039] The side edge of the workpiece plate 11 will contact the chamfered portion of the arc plate 23 during the downward movement, and the workpiece plate 11 will exert pressure on the arc plate 23 through the chamfered portion to cause the arc plate 23 to move downward. The downwardly moved arc plate 23 will move downward on the surface of the vertical rod 7 using the sleeve 24, and the downwardly moved sleeve 24 will cooperate with the second spring 25 that squeezes the surface of the vertical rod 7. At this time, the output end of the cylinder is controlled to move the slide 12, so that the workpiece plate 11 is conveniently aligned with the top of the pressure ring 8, and the elastic force of the second spring 25 rebounds. At this time, the sleeve 24 drives the arc plate 23 to move upward, so that the workpiece plate 11 can be conveniently placed on the top surface of the pressure ring 8.

[0040] The workpiece plate 11 moves downward between the two arc-shaped plates 23. When the side edge of the workpiece plate 11 moves downward and contacts the top surface of the rotating plate 32, the workpiece plate 11 squeezes the rotating plate 32 to cause the rotating plate 32 to rotate. Since the top of the rotating plate 32 is rotated and clamped on the inner side of the arc-shaped plate 23, the bottom end of the rotating rotating plate 32 drives the push plate 29 to move downward using the side plate 33. In the process of moving downward, the push plate 29 gradually moves away from the arc-shaped plate 23. The moving push plate 29 cooperates with the pulling of the elastic strip 31, and the elastic strip 31 is pulled downward. The push plate 29 31 is deformed and lengthened, and gradually moves away from the arc plate 23, driving the inner rod 27 to squeeze the spring piece 30 on the inner side of the through groove until the bottom end of the rotating plate 32 rotates to the inside of the arc plate 23. At this time, the workpiece plate 11 continues to move downward until the workpiece plate 11 is separated from the rotating plate 32. The elastic force of the elastic strip 31 and the spring piece 30 causes the push plate 29 to move upward and close to the arc plate 23. The push plate 29 uses the side plate 33 to make the bottom end of the rotating plate 32 rotate to the top of the workpiece plate 11 again.

[0041] The workpiece plate 11 is placed on the top surface of the pressure ring 8, and the screw sleeve is screwed, and the screw sleeve moves downward on the surface of the vertical rod 7. The downwardly moved screw sleeve uses the collar 24 to drive the arc plate 23 and the rotating plate 32 to move downward until the bottom end of the rotating plate 32 corresponds to the top surface of the workpiece plate 11, so that workpiece plates 11 of different thicknesses can be placed on the top of the pressure ring 8. At this time, the bottom end of the rotating plate 32 does not contact the top surface of the workpiece plate 11, and the two opposite arc plates 23 place the workpiece plate 11 on the top surface of the pressure ring 8, and the two opposite rotating plates 32 prevent the workpiece plate 11 from tilting on the top surface of the pressure ring 8.

[0042] Start the second cylinder 9, and the output end of the second cylinder 9 pushes the lower pressure block 10 to move upward. The lower pressure block 10 moves upward at the center of the pressure ring 8, and the top of the lower pressure block 10 squeezes the workpiece plate 11 until the lower pressure block 10 moves to the bottom opening of the upper die 6. The workpiece plate 11 is deformed inside the bottom opening of the upper die 6. The lower pressure block 10 cooperates with the upper die 6 to form a cookware workpiece inside the bottom opening of the upper die 6. The output end of the first cylinder 5 causes the lifting plate 4 to drive the upper die 6 to move upward, and the second cylinder 9 causes the lower pressure block 10 to move downward, and the cookware workpiece is formed on the top surface of the pressure ring 8.

[0043] After the hydraulic pressure of the workpiece plate 11 is completed, the output end of the third cylinder 13 moves the slide 12 upward, and the output end of the control cylinder causes the slide 12 to drive the connecting component to move right. After the connecting component moves to the top of the cookware workpiece, the output end of the third cylinder 13 moves the slide 12 downward, and the slide 12 uses the connecting component to absorb the cookware workpiece on the top surface of the pressure ring 8, and the output end of the control cylinder causes the slide 12 to drive the connecting component and the cookware workpiece to move left, so as to facilitate the removal of the cookware workpiece from the top surface of the pressure ring 8. At this time, the connecting component on the right side replaces the workpiece plate 11 to be hydraulically pressurized on the top surface of the pressure ring 8, so as to facilitate continuous hydraulic processing of multiple workpiece plates 11.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
