Description

Technical Field

[0001] The present invention belongs to the field of hot pressing forming of rubber parts, and particularly relates to an efficient hot pressing forming device for rubber parts and its hot pressing forming process. Background Art

[0002] Most of the existing rubber parts are formed by hot pressing through the ductility of rubber. Generally, a rubber strip is placed between extrusion molds for extrusion forming. Generally, the mold consists of an upper mold and a lower mold. The upper mold is generally controlled by a lifting device to move up and down for extrusion forming. However, when the cut rubber strip is placed in the lower mold, it is easy to have wrinkles and unevenness, and the strip is difficult to fill the lower mold, which affects the finished product effect of hot pressing.

[0055] S8. Transfer operation on the strip: After removing the strip that has completed hot pressing and forming, by opening the material grasping component, the material grasping and transfer operation of the hot pressed and formed strip can be completed.

[0056] Generally speaking, compared with the prior art, the beneficial effects of the above technical solutions conceived by the present invention include:

[0057] 1. For the high-efficiency rubber part hot pressing and forming equipment and its hot pressing and forming process of the present invention, through the arranged hot pressing and forming component, the staff can drive the forming upper die to drive the forming template to move downward as a whole by opening the third electric cylinder. When the forming template penetrates into the forming lower die, the forming upper die and the forming lower die can be in a closed die state to complete the hot pressing and forming operation of the rubber strip;

[0058] 2. For the high-efficiency rubber part hot pressing and forming equipment and its hot pressing and forming process of the present invention, through the arranged energy storage triggering component, when the staff opens the first downward movement of the forming upper die, the stepped block can be driven to move downward synchronously. After the stepped block moves downward, the pressing wheel can be driven to move leftward. During the process of the pressing wheel moving leftward, the toothed plate can be made to move leftward for the first time. During the process of the toothed plate moving leftward for the first time, the blank holding component can be driven to perform positive blank holding operation on the rubber strip that has not been hot pressed and formed. When the forming upper die moves downward for the second time, the toothed plate can be driven to continue moving leftward to drive the blank holding component to move downward again to continue performing side blank holding operation after completing the positive blank holding operation on the rubber strip;

[0059] 3. The high-efficiency rubber part hot pressing forming equipment and its hot pressing forming process of the present invention, through the arranged energy storage trigger member, and through the continuously arranged first step and second step, on the one hand, it can make the energy storage spring move towards the telescopic trend in the state of compression trend, so that the energy storage spring can move towards the second step when the first step moves downward. On the other hand, through this ingenious design, the positive edge pressing operation on the rubber part that has not been hot pressed can be completed during the hot pressing forming process. On the other hand, during the process of the first step converting to the second step, the edge pressing member can be made to move downward again to complete the edge pressing operation on both sides of the rubber part strip that has not been hot pressed. In addition, through the arrangement of the first step and the second step, the fourth electric cylinder can be activated to actively contact the second step or the first step to realize independent control of the positive edge pressing operation on the strip. By activating the fourth electric cylinder, the energy storage spring can be lifted to directly contact the second step, which is equivalent to the edge pressing member having only a single downward operation, that is, it can only independently control the positive edge pressing operation on the rubber part strip once. In addition, by activating the fourth electric cylinder, the energy storage spring can be made not to contact the second step or the first step to release the activation of the edge pressing member;

[0060] 4. The high-efficiency rubber part hot pressing forming equipment and its hot pressing forming process of the present invention, through the arranged edge pressing member, when the upper forming die moves downward once, it can trigger the left movement of the toothed plate, and then the toothed plate drives the driving wheel to rotate to drive the second driven wheel to rotate. After the second driven wheel rotates, it can synchronously drive the ball base and the edge pressing part to move downward. After the edge pressing part moves downward, it can enter the lower forming die to complete the positive edge pressing operation on the rubber part strip that has not been hot pressed, and can prevent the situation that the rubber part strip that has not been hot pressed is wrinkled and uneven and cannot be filled into the lower forming die;

[0061] 5. The high-efficiency rubber part hot pressing and forming equipment and its hot pressing and forming process of the present invention, through the arranged edge pressing parts, after the forming upper die performs the second downward movement operation, can drive the edge pressing parts to perform the downward movement operation again. On the one hand, it can further promote the positive edge pressing operation of the edge pressing plate on the unhot-pressed rubber part strip. On the other hand, after the downward movement of the edge pressing plate, it can push the insertion rod upward. After the insertion rod moves upward, the conical surface can move upward, and the side supports can be continuously pushed out to complete the side edge pressing operation of the rubber part, and the unhot-pressed rubber part strip can be more effectively arranged in the forming lower die to efficiently realize the hot pressing and forming operation of the rubber part. In addition, on the other hand, during the second downward movement of the edge pressing parts, it can also drive the tail rod to perform the downward movement operation synchronously. During the downward movement of the tail rod, it can push the inclined surface to move leftward to drive the trigger rod to move leftward. During the leftward movement of the trigger rod, it can synchronously push the extrusion plate, so that the extrusion rod penetrates into the forming lower die to perform the pushing operation on the rubber part strip that has completed the hot pressing and forming, and can loosen the rubber part strip that has completed the hot pressing and forming in the first time to prevent the situation that the rubber part strip after hot pressing and forming adheres to the forming lower die and is difficult to remove.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0088] The terms used herein are only for describing specific embodiments and are not intended to limit the present invention. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations and / or components, but do not exclude the presence or addition of one or more other features, steps, operations or components

[0089] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those of ordinary skill in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner

[0090] In the embodiment, by Figure 1-14Provided is an efficient hot pressing forming device for rubber parts, including a workbench 1, on which a feeding member 2, a clamping and transferring member 3 and a positioning and cutting member 4 are arranged. The feeding member 2 includes a feeding rack 21 arranged on the workbench 1, on which a material tray 22 for a rubber part tape to pass through is arranged, and multiple groups of fabric shafts 23 are arranged on the feeding rack 21. On one side of the feeding rack 21, there is a feeding base 24. The clamping and transferring member 3 includes a clamping and transferring machine frame 31, on which a transferring cylinder 32 is arranged, and a clamping cylinder 33 is arranged on the transferring cylinder 32. The positioning and cutting member 4 includes a cutting machine frame 41, on which a bearing platform 42 and a first electric cylinder 43 are arranged, and a pressure plate 44 is arranged on the first electric cylinder 43. A second electric cylinder 45 is also arranged on the cutting machine frame 41, and a cutting knife 46 is arranged on the second electric cylinder 45. It further includes a double-station feeding member 5 for carrying the cut rubber part tape, which is detachably arranged on the workbench 1 and is composed of a driving end and two station ends connected to the driving end; a hot pressing forming member 6 for hot pressing and forming the rubber part tape, which is detachably arranged on the workbench 1; an energy storage triggering member 7, which is detachably installed on the hot pressing forming member 6 and can be triggered when the hot pressing forming member 6 moves downward; a pressing edge member 8, which is detachably installed on the workbench 1 and can move downward to perform a positive pressing edge operation on the rubber part tape located within the station end when the energy storage triggering member 7 is triggered once; and when the energy storage triggering member 7 is triggered twice, it can trigger the pressing edge member 8 to continue moving downward to perform a side pressing edge operation on the rubber part tape within the station end; a material grabbing member 9 for grabbing the rubber part tape after hot pressing and forming, which is arranged on the workbench 1.

[0091] First, further explanation is needed for the overall use of the feeding member 2, the clamping and transferring member 3 and the positioning and cutting member 4. When fabricating the rubber part tape, place the rubber part material tray on the material tray 22, pull out the rubber part tape, and pass it through multiple groups of fabric shafts 23 and a group of feeding bases 24 in sequence. When using the clamping and transferring member 3, since the clamping and transferring member 3 is located on one side of the feeding member 2, when positioning and clamping the tape head with the clamping cylinder 33, the clamping and pulling operation of the rubber part tape can be completed by turning on the transferring cylinder 32. When cutting the rubber part tape, first place the tape head of the rubber part above the bearing platform 42, and move downward by turning on the first electric cylinder 43 to make the pressure plate 44 perform a positioning operation on the tape head of the rubber part, and then turn on the second electric cylinder 45 to make the cutting knife 46 move downward to complete the first splitting operation of the rubber part tape. This is the first splitting process.

[0092] Next, a more specific structure and configuration are given to the double-station feeding member 5 for further explanation. The driving end of the double-station feeding member 5 includes a first linear module 51 disposed on the workbench 1; a rotary cylinder 52 disposed on the moving end of the first linear module 51; a carrier plate 53 disposed on the output end of the rotary cylinder 52; the station end of the double-station feeding member 5 includes a forming lower die 54, and a pressing rod 56 is slidably disposed on the side of the forming lower die 54. A pressing plate 55 is connected to the tail end of the pressing rod 56, and a pressing spring 57 is sleeved on the pressing rod 56;

[0093] Next, the working principle of the entire double-station feeding member 5 is further explained. Since initially, one set of forming lower dies 54 is located below the positioning and cutting member 4, after the rubber part strip is cut once, it can fall into the forming lower die 54. Subsequently, by turning on the rotary cylinder 52, the set of forming lower dies 54 that has completed loading the material can be rotated, and by turning on the first linear module 51, the forming lower die 54 into which the rubber part strip is to be loaded is sent below the positioning and cutting member 4, and the operation of loading the strip into the second set of forming lower dies 54 continues. Since the strip that falls into the forming lower die 54 is in a wrinkled and uneven state, during actual hot pressing and forming, if no edge pressing is performed, it will affect the effect of the hot pressing and forming finished product;

[0094] In addition, it should be noted that the first linear module 51 is a known component in the prior art, so it is not described in detail in the present invention. The first linear module 51 drives the lead screw to rotate through a motor, and drives the ball base to move left and right through the lead screw, so it is not elaborated in the invention.

[0095] Next, a more specific structure and configuration are given to the hot pressing and forming member 6 for further explanation. The hot pressing and forming member 6 includes a mounting frame 61 disposed on the workbench 1; a mounting plate 62 disposed on the mounting plate 62, and a third electric cylinder 63 is disposed on the mounting plate 62; a forming upper die 64 disposed on the output end of the third electric cylinder 63, and a forming template 65 is disposed on the forming upper die 64. Among them, when the forming template 65 penetrates into the forming lower die 54, the forming upper die 64 and the forming lower die 54 can be in a closed die state;

[0096] Next, the working principle of the entire hot pressing and forming member 6 is further explained. The staff turns on the third electric cylinder 63 to make the forming upper die 64 drive the forming template 65 to move downward as a whole. When the forming template 65 penetrates into the forming lower die 54, the forming upper die 64 and the forming lower die 54 can be in a closed die state to complete the hot pressing and forming operation of the rubber part strip.

[0097] Next, a more specific structure and configuration are given to the overall energy storage trigger member 7 for further explanation. The energy storage trigger member 7 includes a connecting frame 71 which is arranged on the workbench 1, and a cross plate 72 is arranged on the connecting frame 71; a fourth electric cylinder 73 which is arranged on the cross plate 72, and a displacement plate 74 is arranged on the output end of the fourth electric cylinder 73; a fifth electric cylinder 75 which is arranged on the displacement plate 74, and a connecting base plate 76 is detachably arranged on the output end of the fifth electric cylinder 75; a stepped block 77 which is arranged on the forming upper die 64; an energy storage rod 78 which is slidably arranged in the connecting base plate 76, a pressing wheel 79 is arranged at the tail end of the energy storage rod 78, and a toothed plate 792 is arranged on the pressing wheel 79; an energy storage spring 791 which is removably arranged on the energy storage rod 78;

[0098] Next, the working principle of the overall energy storage trigger member 7 is further explained. When the staff opens the downward movement of the forming upper die 64 once, it can drive the stepped block 77 to move downward synchronously. After the stepped block 77 moves downward, it can drive the pressing wheel 79 to move leftward. During the process of the pressing wheel 79 moving leftward, it can make the toothed plate 792 move leftward for the first time. During the process of the toothed plate 792 moving leftward for the first time, it can drive the edge pressing member 8 to make the edge pressing member 8 perform positive edge pressing operation on the rubber strip that has not been hot-pressed and formed. When the forming upper die 64 moves downward for the second time, it can drive the toothed plate 792 to continue moving leftward to drive the edge pressing member 8 to move downward again to continue the side edge pressing operation after completing the positive edge pressing operation on the rubber strip;

[0099] In some embodiments, more specifically, the stepped block 77 has a first step, a second step and a sealing surface. There is an inclined slope on the first step, and a second inclined slope on the second step. In the initial position, the pressing wheel 79 abuts against the lowest point of the first step;

[0100] Next, when the hot-pressing forming member 6 moves once, it can drive the pressing wheel 79 to move along the lowest point of the first step towards the first inclined slope and abut against the lowest point of the second step; when the hot-pressing forming member 6 moves twice, it can drive the pressing wheel 79 to move along the lowest point of the second step towards the second inclined slope and abut against the sealing surface;

[0101] Due to the continuously arranged first step and second step, on the one hand, the energy storage spring 791 can move towards the telescopic trend in the state of compression trend, so that the energy storage spring 791 can move towards the second step when the first step moves downward. On the other hand, through this ingenious design, the positive edge pressing operation on the rubber parts that have not been hot-pressed can be completed during the hot pressing process. On the other hand, during the process of the first step converting to the second step, the edge pressing member 8 can be made to move downward again to complete the edge pressing operation on both sides of the strip of the rubber parts that have not been hot-pressed. In addition, through the arrangement of the first step and the second step, the fourth electric cylinder 73 can be activated to actively contact the second step or the first step to realize independent control of the positive edge pressing operation on the strip. By activating the fourth electric cylinder 73, the energy storage spring 791 can be lifted so that 793 directly abuts against the second step. Then, it is equivalent that the edge pressing member 8 only has a single downward operation, which is equivalent to only being able to independently control the positive edge pressing operation on the strip of the rubber parts independently and once. In addition, by activating the fourth electric cylinder 73, the energy storage spring 791 can be made not to contact the second step or the first step to release the activation of the edge pressing member 8.

[0102] In some embodiments, more specifically, the energy storage spring 791 is located between the pressure wheel 79 and the connecting substrate 76. When the pressure wheel 79 abuts against the lowest point of the first step, the energy storage spring 791 is in a compressed trend. There is also a patch on one end of the energy storage rod 78 that passes through the connecting substrate 76.

[0103] Next, a more specific structure and configuration of the edge pressing member 8 are given for further explanation. The edge pressing member 8 includes a machine frame 81, which is arranged on the workbench 1. There is a top plate 82 on the machine frame 81; a short shaft 821, which is rotatably arranged on the top plate 82. A driving wheel 822 and a first driven wheel 823 are rotatably arranged on the short shaft 821. A belt 824 is sleeved on the first driven wheel 823; a lead screw 83, which is rotatably arranged in the machine frame 81, and the lead screw 83 can pass through the top plate 82. A second driven wheel 84 is arranged on the lead screw 83, and the second driven wheel 84 is bypassed by the belt 824; a ball base 85, which is slidably arranged in the machine frame 81, and the ball base 85 is penetrated by the lead screw 83; an extension plate 86, which is arranged at one end of the ball base 85. Two groups of edge pressing parts 87 are arranged on the extension plate 86; a tail rod 88, which is arranged at the other end of the ball base 85; an outer extension frame 89, which is arranged on the side of the machine frame 81. A trigger rod 891 is slidably arranged in the outer extension frame 89. There is an inclined surface 892 at one end of the trigger rod 891;

[0104] Next, a further explanation of the overall working principle of the blank holder member 8 is given. When the forming upper die 64 moves downward once, it can trigger the leftward movement of the toothed plate 792. Further, the toothed plate 792 drives the driving wheel 822 to rotate, which in turn drives the second driven wheel 84 to rotate. After the second driven wheel 84 rotates, it can synchronously drive the ball base 85 and the blank holder 87 to move downward. After the blank holder 87 moves downward, it can enter the forming lower die 54 to complete the positive blank holding operation on the unthermoformed rubber strip, and can prevent the situation where the unthermoformed rubber strip is wrinkled and uneven and cannot be filled into the forming lower die 54.

[0105] Next, a more specific structure and configuration of the blank holder 87 are given for further explanation. The blank holder 87 includes a blank holding column 871, which is arranged on the extension plate 86. A plug rod 872 is slidably arranged in the blank holding column 871. A blank holding plate 873 is arranged at the bottom of the plug rod 872. A stop piece is provided at one end of the plug rod 872 that penetrates into the blank holding column 871, and a conical surface is provided at the end of the plug rod 872 that penetrates into the blank holding column 871; a built-in spring 874, which is slidably arranged on the plug rod 872; a side support 875, which is slidably arranged on the side surface of the blank holding column 871. An internal spring 876 is connected to the side support 875, and the internal spring 876 is connected to the inner wall of the blank holding column 871. In the initial position, the side support 875 abuts against the highest point of the conical surface;

[0106] Next, a further explanation of the working principle of the blank holder 87 is given. After the forming upper die 64 performs a second downward movement operation, it can drive the blank holder 87 to perform a downward movement operation again. On the one hand, it can further promote the positive blank holding operation of the blank holding plate 873 on the unthermoformed rubber strip. On the other hand, after the blank holding plate 873 moves downward, it can push the plug rod 872 upward. After the plug rod 872 moves upward, the conical surface can move upward, and the side support 875 can be continuously pushed out to complete the side blank holding operation on the rubber part, and can more effectively arrange the unthermoformed rubber strip in the forming lower die 54 to efficiently realize the thermoforming operation of the rubber part; in addition, on the other hand, during the second downward movement of the blank holder 87, it can also drive the tail rod 88 to perform a downward movement operation synchronously. During the downward movement of the tail rod 88, it can push the inclined surface 892 to move leftward to drive the trigger rod 891 to move leftward. During the leftward movement of the trigger rod 891, it can synchronously push the extrusion plate 55 to make the extrusion rod 56 penetrate into the forming lower die 54 to perform a pushing operation on the thermoformed rubber strip, and can loosen the thermoformed rubber strip in the first time to prevent the situation where the thermoformed rubber strip adheres to the forming lower die 54 and is difficult to remove.

[0107] Next, a more specific structure and configuration are given to the entire material-gripping member 9 for further explanation. The material-gripping member 9 includes a second linear module 91, which is detachably arranged on the workbench 1; a gripping module 92 for gripping the rubber part strip that has completed thermocompression molding, which is detachably installed on the second linear module 91;

[0108] Next, the operating principle of the entire material-gripping member 9 is further explained. By turning on the second linear module 91, the gripping module 92 can be quickly moved forward and backward. It should also be noted that the second linear module 91 is a known component in the prior art, so it is not described in detail in the present invention. For details, refer to the structure of the above-mentioned first linear module 51. In addition, the gripping module 92 is also a known structure in the prior art. Please refer to Figure 7 , the structure of the gripping module 92 is that the driving cylinder drives the material plate to move forward or backward. There is a motor on the material plate that can drive the gear to rotate, so as to drive the rotation of the material-gripping cylinder, so as to quickly perform the feeding operation on the strip that has completed thermocompression molding.

[0109] Another technical problem to be solved by the present invention is the thermocompression molding process of an efficient rubber part thermocompression molding device.

[0114] S5. Thermocompression molding operation of the rubber part strip: Turn on the thermocompression molding member 6 to complete the thermocompression molding operation of the rubber part strip;

[0115] S6. Energy storage and triggering operation of the energy storage triggering member 7: During the first downward movement of the thermocompression molding member 6, the energy storage triggering member 7 can be triggered once. When the energy storage triggering member 7 is triggered once, the pressing edge member 8 can be moved downward to perform a positive pressing edge operation on the rubber part strip located at the working station end;

[0116] S7. Secondary energy storage triggering operation on the energy storage triggering member 7: When the hot pressing forming member 6 finishes hot pressing the rubber strip, the energy storage triggering member 7 can be triggered for the second time. When the energy storage triggering member 7 is triggered for the second time, it can trigger the edge pressing member 8 to continue moving downward to perform side edge pressing operation on the rubber strip in the working position end.

[0117] S8. Transfer operation of the strip: After removing the strip that has completed hot pressing forming, by opening the material grasping member 9, the material grasping and transfer operation of the hot pressed forming strip can be completed.
