Description

Technical Field

[0001] This invention relates to the field of strip cutting technology, specifically to a fully automatic wear-resistant ring cutting equipment. Background Technology

[0002] For the production of existing wear-resistant rings, there are two methods: integral molding and strip cutting and butt welding. The latter involves cutting the continuous roll of wear-resistant strip (also known as guide strip or wear-resistant strip material) into single strips of a set length, and then joining the two ends of the strips together (through hot melting, bonding, ultrasonic welding, etc.) to form a closed ring. This method has advantages such as low mold cost, high material utilization rate, and flexible specification switching, and is gradually becoming the mainstream process for multi-variety, small-batch production.

[0003] Existing equipment mostly uses blade extrusion or punching methods for cutting. For high-molecular wear-resistant strips represented by polytetrafluoroethylene (PTFE) composite materials and phenolic fabric, which have characteristics such as high elongation at break, softness and easy deformation, and poor thermal conductivity, the blade extrusion process is actually "tearing" or "crushing" the material, rather than a clean cut. As a result, the following defects exist in actual operation: burrs, crushing or delamination are easily generated on the cut end face, which creates gaps or steps when the strips are joined, seriously affecting the subsequent processing and use effect. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic wear-resistant ring cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic wear-resistant ring cutting device, including a base; a guiding mechanism installed on the base for conveying strip material; a sawing mechanism including a driving component and a saw blade installed on the base; and a clamping mechanism installed on the base; wherein the angle between the cutting plane of the saw blade and the strip material conveying direction is 45°, and the driving component is used to drive the saw blade to feed in a direction at a 45° angle to the horizontal plane containing the strip material conveying direction.

[0006] Preferably, the guiding mechanism includes a support plate slidably connected to one side of the support; multiple first synchronous wheels are symmetrically distributed vertically and are rotatably connected to one side of the support and the support plate respectively; and several of the synchronous wheels at the top can move vertically.

[0007] Preferably, the drive unit includes a base, which is fixedly connected to the base; an electric slide is mounted on the base, and the saw blade is mounted on the electric slide.

[0008] Preferably, the clamping mechanism includes a pressure table, and the interior of the pressure table has a cutting groove adapted to the feed direction of the saw blade.

[0009] Preferably, the clamping mechanism further includes two clamping cylinders, which are fixedly installed on the base, and their bottom ends are fixedly connected to a pressure plate located above the pressure table.

[0010] Preferably, a drive motor and two second synchronous pulleys are respectively provided on the side of the support away from the first synchronous pulley.

[0011] Preferably, the output shaft of the drive motor is fixedly connected to a second synchronous pulley via a coupling, and another second synchronous pulley is rotatably connected to the side of the support and coaxially driven with a first synchronous pulley at the top.

[0012] Preferably, an adjusting plate is slidably connected to one side of the support, and a guide cylinder is fixedly connected to the top of both the adjusting plate and the support plate.

[0013] Preferably, the guide cylinder is fixedly installed on the support.

[0014] Preferably, one side of the adjusting plate and one side of the support are rotatably connected to an encoding wheel, and the two encoding wheels are distributed vertically.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a saw blade positioned at a 45° angle to the strip conveying path to cut into the strip at this angle. This decomposes the cutting force into horizontal and vertical components, resulting in a more uniform distribution of cutting force. This reduces material tearing caused by localized stress concentration, helps stabilize the cut, reduces burrs on the end face, and reduces visible gaps or steps during subsequent processing, thus improving the subsequent processing and usage effects.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-6 As shown, the fully automatic wear-resistant ring cutting equipment includes a base 100; a guide mechanism 200, installed on the base 100, for conveying strip material; a sawing mechanism 300 including a drive component 310 and a saw blade 320 installed on the base 100; and a clamping mechanism 400 installed on the base 100. The angle between the cutting plane of the saw blade 320 and the strip material conveying direction is 45°, and the drive component 310 is used to drive the saw blade 320 to feed in a direction that forms a 45° angle with the horizontal plane containing the strip material conveying direction.

[0020] When cutting the strip, after the equipment is started, the guide mechanism 200 positions and conveys the strip. Then, when the strip reaches the clamping mechanism 400, the clamping mechanism 400 aligns with the clamping limit to ensure stable positioning during cutting. Subsequently, the drive component 310 on the sawing mechanism 300 drives the cutting saw blade 320 to move and advance in a 45° direction to complete the cutting.

[0021] The guide mechanism 200 includes a support plate 211 slidably connected to one side of the support 210; multiple first synchronous wheels 220 are distributed symmetrically in the upper and lower parts and are rotatably connected to one side of the support 210 and the support plate 211 respectively; and several synchronous wheels at the top can move vertically.

[0022] Two synchronous belts are installed on the outer side of the upper and lower first synchronous pulleys 220. They are installed before the strip cutting operation, and then the synchronous belts are used to fit the strip to complete the positioning and conveying.

[0023] It should be noted that rubber pads can be added to the outer side of the timing belt for anti-slip treatment, such as... Figure 5As shown, the five first synchronous pulleys 220 at the top are vertically movable. During the movement, the top synchronous belt follows the movement, and the transmission teeth on the inner side of the synchronous belt are arc teeth, not trapezoidal teeth, which improves the meshing tolerance and reduces the occurrence of tooth skipping and jamming during the movement. The vertical movement amplitude of the top synchronous belt is ≤10mm, ensuring the feasibility of the vertical movement and not affecting the cooperation and transmission between the synchronous belt and the first synchronous pulleys 220.

[0024] The drive unit 310 includes a base 311 fixedly connected to the base 100; an electric slide 312 is mounted on the base 311, and a saw blade 320 is mounted on the electric slide 312.

[0025] When pushing the saw blade 320 in and out, the electric slide 312 on the base 311 can be activated to drive the saw blade 320 to move.

[0026] It should be noted that the specifications of the electric slide table 312 can be selected according to actual usage requirements to meet the cutting speed required for different strips, and the saw blade 320 is driven by a servo motor, which is fixedly installed on the mounting base on the top of the electric slide table 312.

[0027] The clamping mechanism 400 includes a pressure table 410, the interior of which is provided with a cutting groove adapted to the feed direction of the saw blade 320, and the width of the cutting groove is greater than the thickness of the saw blade 320; there are two clamping cylinders 420, which are fixedly installed on the base 100, and their bottom ends are fixedly connected to a pressure plate 421 located above the pressure table 410.

[0028] During the conveying process of the strip, it will be placed on the pressure plate 421. When it needs to be fixed, the clamping cylinder 420 operates, causing the pressure plate 421 to move downward and press against the strip to complete the limit.

[0029] On the side of the support 210 away from the first synchronous pulley 220, a drive motor 212 and two second synchronous pulleys 213 are respectively provided. The output shaft of the drive motor 212 is fixedly connected to one of the second synchronous pulleys 213 through a coupling. The other second synchronous pulley 213 is rotatably connected to the side of the support 210 and coaxially driven with one of the top first synchronous pulleys 220.

[0030] Before the cutting operation, a corresponding synchronous belt is installed between the two second synchronous pulleys 213. Thus, during the positioning and conveying of the strip, after the drive motor 212 operates, the second synchronous pulleys 213 rotate accordingly. Figure 6 As shown, the second synchronous pulley 213 on the left side and the first synchronous pulley 220 on the top left side are driven on the same axis, thereby driving the remaining synchronous pulleys at the top to move and complete the positioning and conveying of the strip.

[0031] It should be noted that the drive of the bottom first synchronous pulley 220 can be driven by a corresponding electric motor added to the side of the support 210, or it can be driven without power output. The specific usage method can be selected according to the processing requirements.

[0032] An adjusting plate 214 is slidably connected to one side of the support 210. A guide cylinder 215 is fixedly connected to the top of both the adjusting plate 214 and the support plate 211. The guide cylinder 215 is fixedly installed on the support 210. An encoding wheel 216 is rotatably connected to one side of the adjusting plate 214 and one side of the support 210. The two encoding wheels 216 are distributed vertically.

[0033] The user can drive the corresponding guide cylinder 215 to make the support plate 211 and the adjusting plate 214 move vertically, and adjust the position of the top synchronous belt or the position of the encoder wheel 216. The use of the encoder wheel 216 makes it easy to achieve counting and fixed length during the conveying of the belt.

[0034] It should be noted that the encoder wheel 216 contacts the surface of the strip and rotates passively as the strip is conveyed. The encoder wheel 216 has a built-in angle sensor that converts the rotation angle into a pulse signal and sends it to the external PLC controller.

[0035] Working Principle: Before performing strip cutting, the equipment needs to be debugged and prepared. First, adjust the positions of the support plate 211 and the adjusting plate 214 according to the width of the strip to be cut, so that the guide mechanism 200 adapts to the strip size. Then, corresponding synchronous belts are fitted onto the upper and lower sets of first synchronous pulleys 220 respectively. The inner transmission teeth of the top synchronous belt are rounded teeth to improve meshing tolerance. At the same time, a transmission synchronous belt is fitted between the two second synchronous pulleys 213 to complete the power transmission configuration. After completing the preparation work, the equipment is started to begin the cutting operation. The drive motor 212 operates, and its output shaft drives one of the second synchronous pulleys 213 to rotate through the coupling. This second synchronous pulley 213 transmits power to the other second synchronous pulley 213 through the synchronous belt. Since the corresponding first synchronous pulley 220 and the corresponding The second synchronous pulley 213 is coaxially driven, and the power is further transmitted to the first synchronous pulleys 220 at the top, driving the top synchronous belt to move. The bottom first synchronous pulley 220 can be driven by an independent motor or have no power output. The upper and lower synchronous belts are driven by the guide cylinder 215 to achieve vertical opening and closing, thereby forming a stable pressing and adhesion of the belt material and completing the positioning and conveying. The belt material is conveyed forward under the clamping of the upper and lower synchronous belts. When it passes the coding wheel 216, the two coding wheels 216 distributed at the top and bottom perform contact counting on the belt material to achieve fixed length measurement. When the belt material is conveyed to the preset length, the belt material enters the pressing mechanism 400 area. At this time, the belt material is between the pressing table 410 and the pressing plate 421. The two pressing cylinders 420 operate simultaneously, pushing the pressing plate 421 to move downward and pressing and fixing the belt material on the pressing table 410. The pressure table 410 has a cutting groove inside that matches the feed direction of the saw blade 320, providing clearance for subsequent cutting. Then, the sawing mechanism 300 performs the cutting action, the electric slide table 312 starts, and drives the saw blade 320 mounted on it to feed. The angle between the cutting plane of the saw blade 320 and the strip conveying direction is 45°. The saw blade 320 is driven by a servo motor to rotate at high speed. The saw blade 320 cuts into the strip under the push of the electric slide table 312, and completes the cutting at a 45° direction. During the cutting process, the cutting groove provides passage space for the saw blade 320 to ensure smooth cutting. After the cutting is completed, the electric slide table 312 drives the saw blade 320 back to the initial position, the clamping cylinder 420 drives the pressure plate 421 to rise and release the strip, and the upper and lower synchronous belts continue to convey the cut strip out of the equipment to enter the next working cycle.
