Description

Technical Field

[0001] The present invention relates to the technical field of turning equipment, and particularly relates to a production device and process for corrugated tooth composite gaskets. Background Art

[0002] The corrugated tooth composite gasket is a high-performance sealing element, commonly used for flange connections of high-pressure pipelines, containers and equipment, and can effectively prevent medium leakage under harsh conditions such as high temperature, high pressure and corrosive media.

[0003] Chinese Patent with the authorization announcement number CN117840788B discloses a processing device for corrugated tooth composite gaskets, including a machine body. A cutting mechanism and a moving mechanism are provided on the machine body. The moving mechanism is used to drive the cutting mechanism to move on the machine body and cut the workpiece. A clamping mechanism is also provided on the machine body. The clamping mechanism includes an inner support component, an outer support component, an adjustment component, a driving component and a fixing component. The inner support component includes a plurality of inner support blocks, and the inner support blocks are circumferentially spaced apart. The outer walls of the inner support blocks are used to fit the inner circle of the workpiece. The outer support component includes a plurality of outer support blocks, and the outer support blocks are circumferentially spaced apart. The inner walls of the outer support blocks are used to fit the outer circle of the workpiece. An annular space for placing the workpiece is formed between the inner support component and the outer support component. The inner support component and the outer support component are connected by an adjustment component, and the adjustment component is used to adjust the gap between the inner support component and the outer support component to cooperate with each inner support block and each outer support block to clamp workpieces of different models. The driving component is used to drive the inner support component and the outer support component to clamp and rotate the workpiece. The fixing component is used to fit the two annular end faces of the workpiece to fix the workpiece. When processing the workpiece, the inner support component and the outer support component cooperate to clamp the inner circle and the outer circle of the workpiece at the same time. Through the setting of the fixing component, the two annular end faces of the workpiece in the axial direction are further clamped during the processing. Then the driving component drives the workpiece to rotate, and the cutting mechanism is driven by the moving mechanism to fit the surface of the workpiece, and a corrugated ring groove is cut on the surface of the workpiece.

[0004] The problem existing in the above-mentioned corrugated tooth composite gasket processing device during use is that when processing the corrugated ring groove on the side surface of the corrugated tooth composite gasket, the chips cut by the tool are strip-shaped, and the strip-shaped chips cut by the tool may be wound around the tool. After the chips are wound around the tool, if the tool continues to cut the corrugated tooth composite gasket, it will cause an increase in the cutting resistance received by the tool, thereby increasing the wear of the tool and accelerating the damage of the tool. Summary of the Invention

[0005] The present invention provides a production device and process for corrugated tooth composite gaskets, aiming to solve the problem existing in the above-mentioned prior art that the strip-shaped chips cut during the use of the corrugated tooth composite gasket processing device may be wound around the tool, resulting in an increase in the cutting resistance received by the tool and accelerating the damage of the tool.

[0006] In a first aspect, the production device for wave-tooth composite gaskets provided by the present invention adopts the following technical solutions:

[0007] A production device for wave-tooth composite gaskets includes a machine body, a cutting mechanism disposed on the machine body, and a rotating mechanism for driving the wave-tooth composite gasket to rotate around its axis in a horizontal plane. The cutting mechanism includes a mounting seat, a cutting tool, and a first elastic member. The cutting tool is provided with a cutting surface, and in the rotation direction of the wave-tooth composite gasket, the cutting surface is inclined with the front end lower and the rear end higher. The cutting tool is slidably arranged up and down on the mounting seat. One end of the first elastic member is connected to the mounting seat, and the other end is connected to the cutting tool. When cutting the gasket, the first elastic member elastically presses the cutting tool against the gasket. The mounting seat is further provided with a lifting mechanism, which includes a position detector, a controller, and a lifting driving member. The lifting driving member is in transmission connection with the cutting tool to drive the cutting tool to lift. The position detector is used to detect the position of the cutting tool. During the process of cutting the gasket, when the cutting resistance received by the cutting tool increases and causes the cutting tool to be lifted to a preset position, the position detector sends a rising signal to the controller, and the controller controls the lifting driving member to drive the cutting tool to rise, so that the cutting tool no longer cuts the gasket.

[0008] The beneficial effects are as follows: When the production device for wave-tooth composite gaskets of the present invention is in use, the wave-tooth composite gasket to be processed is placed on the rotating mechanism, the first elastic member elastically presses the cutting tool against the gasket, and then the rotating mechanism is controlled to drive the wave-tooth composite gasket to rotate around its axis in a horizontal plane. During the rotation of the wave-tooth composite gasket, the cutting tool cuts out a wave-shaped annular groove on its surface. When the long strip-shaped debris cut by the cutting tool winds around the cutting tool, the cutting resistance received by the cutting tool increases. At this time, the extrusion force received by the cutting surface on the cutting tool increases, which will squeeze the cutting tool to move upward and compress the first elastic member. When the cutting tool is lifted to the preset position, the position detector sends a rising signal to the controller, and the controller controls the lifting driving member to drive the cutting tool to rise, so that the cutting tool no longer contacts the wave-tooth composite gasket and no longer cuts the gasket. Then the staff cleans the long strip-shaped debris wound on the cutting tool, and then controls the lifting driving member to drive the cutting tool to descend to continue processing. When the production device for wave-tooth composite gaskets of the present invention is in use, when the cutting resistance received by the cutting tool increases, the cutting tool will move upward and compress the first elastic member, and then trigger the controller to control the lifting driving member to drive the cutting tool to rise, so that the cutting tool no longer contacts the wave-tooth composite gasket and no longer cuts the gasket, thereby preventing the cutting tool from cutting under a large cutting resistance, delaying the wear of the cutting tool, and extending the service life of the cutting tool.

[0009] Preferably, a connecting member is fixedly provided on the cutting tool. One end of the first elastic member is fixedly connected to the mounting seat, and the other end is fixedly connected to the connecting member. A first vertical sliding hole is formed in the connecting member, and the connecting member is slidably sleeved on the telescopic rod of the lifting driving member through the first vertical sliding hole. A first stop member is provided at the lower end of the telescopic rod of the lifting driving member. When the first stop member moves upward, it can contact the connecting member and then drive the connecting member to move upward.

[0010] Preferably, the lifting mechanism further includes an emergency lifting member. A second vertical sliding hole is further formed in the connecting member. The connecting member is slidably sleeved on the telescopic rod of the emergency lifting member through the second vertical sliding hole. A second stop member is provided at the lower end of the telescopic rod of the emergency lifting member. When the second stop member moves upward, it can abut against the connecting member and then drive the connecting member to move upward.

[0011] The beneficial effect is that when emergency shutdown is required, the tool can be driven by the emergency lifting member to rise away from the serrated composite gasket, and no longer cut the gasket.

[0012] Preferably, the lifting mechanism further includes a vertically arranged damping telescopic rod. The damping telescopic rod includes a first rod and a second rod. The first rod is slidably inserted into the second rod, and the first rod can extend out of the second rod. The upper end of the first rod is fixedly connected to the connecting member. A second elastic member is further provided on the second rod. One end of the second elastic member is fixedly connected to the second rod, and the other end is fixedly connected to the mounting seat. The elastic force direction of the second elastic member is along the vertical direction. When cutting the gasket, the lower end of the second rod abuts against the mounting seat, and the second elastic member is in a natural state.

[0013] The beneficial effect is that some types of serrated composite gaskets will have through holes. When the tool passes through the through hole during the cutting process, the damping telescopic rod can prevent the tool from descending, so as to facilitate the tool to continue cutting the serrated composite gasket after passing over the through hole.

[0014] Preferably, a pressing plate is fixedly provided on the second rod. One end of the second elastic member is fixedly provided on the pressing plate. The second elastic member is fixedly connected to the second rod through the pressing plate. The position detector is a push switch. The position detector is arranged above the pressing plate and is vertically slidably arranged on the mounting seat. A third elastic member is further fixedly provided on the position detector. The elastic force direction of the third elastic member is along the vertical direction. One end of the third elastic member away from the position detector is fixedly arranged on the mounting seat. When the tool is lifted to a preset position, it can drive the pressing plate to move upward and squeeze the position detector. When the position detector is squeezed, it sends a rising signal to the controller, and the controller controls the lifting driving member to drive the tool to rise, so that the tool no longer cuts the gasket.

[0015] Preferably, the rotating mechanism includes a roller support assembly and a rotation driving assembly. The roller support assembly is provided with at least three spaced apart in the circumferential direction of the serrated composite gasket. The roller support assembly includes a support roller and a fixed seat. The support roller is rotatably arranged on the fixed seat, and the rotation axis of the support roller is arranged along the radial direction of the serrated composite gasket. The rotation driving assembly is provided with at least two spaced apart in the circumferential direction of the serrated composite gasket. The rotation driving assembly includes a driving wheel, a driven wheel and a driving motor. The output shaft of the driving motor is drivingly connected to the driving wheel to drive the driving wheel to rotate. The rotation axes of the driving wheel and the driven wheel are both vertically arranged. The driving wheel and the driven wheel are respectively located inside and outside the serrated composite gasket, and a clamping space for clamping the serrated composite gasket is formed between the driving wheel and the driven wheel. When the driving wheel rotates, it can drive the serrated composite gasket to rotate.

[0016] Preferably, a blowing member is further provided on the machine body. In the radial direction of the serrated composite gasket, the blowing member is located outside the tool. The blowing direction of the blowing member faces the inside of the serrated composite gasket. The blowing member can blow the chips cut by the tool to the inside of the tool to prevent the chips from winding around the tool.

[0017] The beneficial effect is that the blowing member can prevent the chips cut by the tool from winding around the tool.

[0018] Preferably, a chip collection assembly is further provided on the machine body. The chip collection assembly includes a guide plate and a collection box. In the radial direction of the serrated composite gasket, the guide plate is located inside the tool. A guide inclined surface is provided on the upper surface of the guide plate. In the direction from outside to inside, the guide inclined surface extends from bottom to top. The lower end of the guide inclined surface is lower than the upper surface of the serrated composite gasket, and the upper end of the guide inclined surface is higher than the upper surface of the serrated composite gasket. The collection box is located inside the guide plate, and the collection box is open at the top. When the blowing member blows the chips to move along the guide inclined surface, the chips can fall into the collection box.

[0019] The beneficial effect is that the blowing member blows the chips to move up along the guide inclined surface, which can lift the chips and prevent the chips from rubbing against the serrated composite gasket to a certain extent when the serrated composite gasket rotates. In addition, it is convenient to collect the cut chips.

[0020] Preferably, the chip collection assembly further includes a guide roller. The guide roller is rotatably arranged at the upper end of the guide plate. The rotation axis of the guide roller is horizontally arranged and perpendicular to the blowing direction of the blowing member. A rotation driving member for driving the guide roller to rotate is further provided on the machine body.

[0021] In the second aspect, the serrated composite gasket production process provided by the present invention adopts the following technical solution:

[0022] A serrated composite gasket production process includes the following steps: S1. Select a metal gasket with appropriate thickness and size according to product requirements;

[0023] S2. Use the above-mentioned corrugated-tooth composite gasket production device to machine a corrugated ring groove on the gasket;

[0024] S3. Paste a composite layer on the metal gasket to form a corrugated-tooth composite gasket;

[0025] S4. Conduct quality inspection on the corrugated-tooth composite gasket, and then package and store the corrugated-tooth composite gaskets with qualified quality.

[0026] The beneficial effects of the present invention are as follows: When the corrugated-tooth composite gasket production device of the present invention is in use, when the cutting resistance received by the tool increases, the tool will move upward and compress the first elastic member, and then trigger the controller to control the lifting drive member to drive the tool to rise, so that the tool no longer contacts the corrugated-tooth composite gasket and no longer cuts the gasket, thereby preventing the tool from cutting under a large cutting resistance, delaying the wear of the tool, and extending the service life of the tool. In addition, by setting the damping telescopic rod, when the tool passes through the through hole during the cutting process, the damping telescopic rod can hinder the tool from descending, thereby facilitating the tool to continue cutting the corrugated-tooth composite gasket after passing over the through hole. In addition, the blowing member can prevent the chips cut by the tool from winding around the tool. The chip collection assembly can lift the chips, to a certain extent prevent the friction between the chips and the corrugated-tooth composite gasket when the corrugated-tooth composite gasket rotates, and can also facilitate the collection of the cut chips.

During operation, the outer edge of the serrated composite gasket 9 is clamped in the annular groove 63 of the driving wheel 61, and the inner edge of the serrated composite gasket 9 is clamped in the annular groove 63 of the driven wheel 62.

When the telescopic rod of the lifting drive member 82 moves upward, it can drive the first stop member 85 to move upward. When the first stop member 85 abuts against the connecting member 24, the first stop member 85 can continue to move upward to drive the connecting plate 242 to move upward, thereby driving the tool 22 to move upward, so that the first elastic member 23 is compressed.

[0046] As Figures 4 - 6 shown, the position detector 81 is a push-button switch. The position detector 81 is arranged above the pressing plate 88, and the position detector 81 is vertically slidably arranged on the mounting seat 21. A third elastic member 89 is also fixedly arranged on the position detector 81. The elastic force direction of the third elastic member 89 is along the vertical direction. One end of the third elastic member 89 away from the position detector 81 is fixedly arranged on the mounting seat 21.

One end of the third elastic member 89 is fixedly arranged on the installation plate 213, and the other end is fixedly arranged on the upper side wall of the sliding groove 212. During the process of cutting the gasket, when the cutting resistance received by the tool 22 increases and the tool 22 is pushed up to a preset position, the tool 22 can drive the damping telescopic rod 84 and the pressing plate 88 to move upward, so that the pressing plate 88 presses the pressing contact 811 of the position detector 81. When the position detector 81 is pressed, it sends a rising signal to the controller, and the controller controls the lifting driving member 82 to drive the tool 22 to rise, so that the tool 22 no longer cuts the gasket.

[0047] As Figures 7 - 10As shown, the blowing member 3 is a blower, and the blowing member 3 is fixedly arranged on the machine body 1. In the radial direction of the serrated composite gasket 9, the blowing member 3 is located outside the cutting tool 22, and the blowing direction of the blowing member 3 faces the inside of the serrated composite gasket 9. The blowing member 3 can blow the chips cut by the cutting tool 22 towards the inside of the cutting tool 22 to prevent the chips from winding around the cutting tool 22. The chip collection assembly 4 is fixedly arranged on the machine body 1, and the chip collection assembly 4 includes a guide plate 41, a guide roller 42 and a collection box 43. In the radial direction of the serrated composite gasket 9, the guide plate 41 is located inside the cutting tool 22. The upper surface of the guide plate 41 is provided with a guide inclined surface 411, and the guide inclined surface 411 extends upward from bottom to top in the direction from outside to inside. The lower end of the guide inclined surface 411 is lower than the upper surface of the serrated composite gasket 9, and the upper end of the guide inclined surface 411 is higher than the upper surface of the serrated composite gasket 9. The guide roller 42 is rotatably arranged at the upper end of the guide plate 41, and the rotation axis of the guide roller 42 is horizontally arranged and perpendicular to the blowing direction of the blowing member 3. A rotation driving member (not shown in the figure) for driving the guide roller 42 to rotate is also arranged on the machine body 1. The collection box 43 is located inside the guide plate 41, and the collection box 43 is open at the top. During operation, the blowing member 3 is started, and the blowing member 3 can blow the chips cut by the cutting tool 22 to move upward along the guide inclined surface 411. When the chips move to the guide roller 42, the guide roller 42 can drive the chips to continue to move forward until the chips fall into the collection box 43.

[0048] The implementation principle of the serrated composite gasket production device according to the embodiment of the present invention is as follows: during use, the serrated composite gasket 9 to be processed is placed on the support roller 51 of the rotating mechanism, and the outer edge of the serrated composite gasket 9 is clamped in the annular groove 63 of the driving wheel 61, and the inner edge of the serrated composite gasket 9 is clamped in the annular groove 63 of the driven wheel 62. The first elastic member 23 elastically presses the cutting tool 22 against the gasket, and then the driving motor is controlled to drive the driving wheel 61 to rotate. When the driving wheel 61 rotates, it cooperates with the driven wheel 62 to drive the serrated composite gasket 9 to rotate. During the rotation of the serrated composite gasket 9, the cutting tool 22 cuts out a corrugated annular groove 91 on its surface. The blowing member 3 blows the chips cut by the cutting tool 22 to move upward along the guide inclined surface 411. When the chips move to the guide roller 42, the guide roller 42 can drive the chips to continue to move forward until the chips fall into the collection box 43.

[0049] When the long strip-shaped chips cut by the tool 22 are wound around the tool 22, the cutting resistance on the tool 22 increases. At this time, the extrusion force on the cutting surface 221 of the tool 22 increases, which will squeeze the tool 22 to move upward and compress the first elastic member 23. At the same time, the tool 22 can drive the pressing plate 88 to move upward. When the tool 22 is lifted to a preset position, the pressing plate 88 just presses the pressing contact 811 of the position detector 81, and the position detector 81 sends an ascending signal to the controller. The controller controls the lifting drive member 82 to drive the tool 22 to rise, so that the tool 22 no longer contacts the serrated composite gasket 9. Then the staff clears the long strip-shaped chips wound on the tool 22, and then controls the lifting drive member 82 to drive the tool 22 to descend to continue processing.

[0050] When the serrated composite gasket production device of the present invention is in use, when the cutting resistance on the tool 22 increases, the tool 22 will move upward, and then trigger the controller to control the lifting drive member 82 to drive the tool 22 to rise, so that the tool 22 no longer contacts the serrated composite gasket 9, thereby preventing the tool 22 from cutting under a large cutting resistance, delaying the wear of the tool 22, and extending the service life of the tool 22. The blowing member 3 can prevent the chips cut by the tool 22 from being wound around the tool 22. The chip collection assembly 4 can lift the chips, to a certain extent prevent the chips from rubbing against the serrated composite gasket 9 when the serrated composite gasket 9 rotates, and can also facilitate the collection of the chips.
