Description

Technical Field

[0001] The invention relates to the technical field of bicycle frame cutting, in particular to a cutting device for producing bicycle frames which can adapt to different pipe diameters. Background Art

[0002] As a core load-bearing component, the manufacturing precision of a bicycle frame directly impacts riding safety, lightweight performance, and user experience. With the surge in market demand for personalized customization (such as different sizes, special-shaped tubing, and unique geometric designs) and small-batch flexible production, bicycle riding performance and safety are closely linked to frame precision. A high-precision frame ensures the precise assembly of each component, enhancing the overall stability of the bicycle and making riding more comfortable and safe. Frame welds require precise cutting dimensions.

[0003] The cutting process in traditional frame production usually relies on dedicated equipment. The diameter of frame tubes ranges widely (such as head tubes and seat tubes, ranging from a dozen millimeters to hundreds of millimeters). Traditional equipment requires frequent replacement of fixtures. The application of traditional cutting equipment is relatively limited. When cutting high-strength tubes, the high cutting speed may cause the saw blade to vibrate. When cutting the tube, the vibration of the saw blade may cause the surface of the tube to be cut unevenly, causing damage to the material. Summary of the Invention

[0011] The present invention provides a cutting device for producing bicycle frames that can adapt to different pipe diameters. It has the following beneficial effects: 1. The cutting equipment for producing bicycle frames that can adapt to different pipe diameters, when in use, when clamping frames of different pipe diameters, the pneumatic piston rod moves upward, and the upward movement of the piston rod drives the cross bracket to move upward, and the upward movement of the cross bracket drives the pressure detection device to move upward. Since an inclined slide is provided at one end of the cross bracket, the upward movement of the cross bracket drives the bottom of the fixed clamping rod to slide on the inclined slide, and the sliding of the bottom of the fixed clamping rod drives the entire fixed clamping rod to rotate around the rotating roller. The upward movement of the cross bracket and the rotation of the fixed clamping rod drive the first rotating rod and the second rotating rod to slide on the first limiting hole and the second limiting hole, and the sliding of the second rotating rod and the third rotating rod drives the rotating plate to rotate around the first rotating rod, so that the size of the clamping and fixing can be adjusted according to pipes of different diameters.

[0012] 2. This cutting equipment can adapt to the production of bicycle frames with different pipe diameters. When in use, when the clamping and fixing device clamps and fixes the pipe, the pneumatic piston rod moves upward, and the upward movement of the piston rod drives the cross bracket to move upward, and the upward movement of the cross bracket drives the pressure detection device to move upward. Since an inclined slide is provided at one end of the cross bracket, the upward movement of the cross bracket drives the bottom of the fixed clamping rod to slide on the inclined slide, and the sliding of the bottom of the fixed clamping rod drives the entire fixed clamping rod to rotate around the rotating roller. When the pressure detection device presses against the pipe and clamps and fixes it together with the fixed clamping rod, the pressure detection plate will receive pressure, thereby driving the spring telescopic rod to extend and retract, and the extension and retraction of the spring telescopic rod is triggered to the receiving module. The receiving module receives the pressure signal, thereby adjusting the clamping force, avoiding deformation of the pipe, and ensuring the quality of the finished frame.

[0013] 3. This cutting equipment for bicycle frame production can adapt to different pipe diameters. When in use, when it is necessary to cut pipes into different geometric shapes, the adjusting rod is rotated. The rotation of the adjusting rod drives the threaded worm to rotate. Since the threaded worm is engaged with the threaded worm wheel, the rotation of the threaded worm drives the threaded worm wheel to rotate. The rotation of the threaded worm wheel drives the rotation of the turntable. The rotation of the turntable drives the rotation of the fixed bracket. The rotation of the fixed bracket drives the entire cutting machine to rotate. Therefore, different angles can be adjusted by rotating the adjusting rod to cut pipes of different geometric shapes.

[0014] 4. The cutting equipment for bicycle frame production can adapt to different pipe diameters. When in use, the user holds the handle and rotates it around the connecting rod. The rotation of the handle drives the cutting motor to rotate. The rotation of the cutting motor drives the rotating bracket to rotate around the connecting rod. The rotation of the cutting motor drives the cutting saw blade to cut the pipe. When cutting pipes with higher strength, the cutting saw blade will vibrate more violently. The vibration of the cutting saw blade drives the cutting shell to vibrate. The vibration of the cutting shell triggers the vibration detector. The vibration detector can detect the degree of vibration. When a certain threshold is reached, the vibration detector will send a signal to the controller. The user can adjust the cutting speed of the cutter through the controller, so that the vibration of the cutting saw blade can be slowed down by reducing the cutting speed, thereby avoiding damage to the pipe. During cutting, the torsion spring generates torque due to the rotation of the handle around the center axis of the torsion spring. After the cutting is completed, the torsion spring twists back to resist deformation and thus returns to its original position, thereby driving the cutting saw blade to return to its original position, thereby avoiding unnecessary damage caused by the cutting saw blade cutting the ground when starting again.

[0015] 5. The cutting equipment for bicycle frame production can adapt to different pipe diameters. When in use, water enters the water pipe through the outlet of the high-pressure water pump and is then transported into the cutting shell. The water is transported to the inside of the rotating nozzle and sprayed onto the cutting saw blade for cooling. A rotating motor is fixedly connected to one side of the inner wall of the cutting shell. The rotation of the driving shaft of the rotating motor drives the driving gear to rotate, and the rotation of the driving gear drives the driven gear to rotate. The driven gear is fixedly connected to the water pipe. The rotation of the driven gear drives the water pipe to rotate, and the rotation of the water pipe drives the inclined water outlet pipe to rotate. Since the end of the water pipe away from the water pipe is fixedly connected to multiple groups of inclined water outlet pipes, the water in the water pipe is sprayed from the inclined water outlet pipe and the water outlet hole onto the cutting saw blade. Since the inclined water outlet pipe is at an inclined angle, the water pipe is affected by centrifugal force when it rotates, so that the spraying area is larger and the water outlet speed is faster, thereby achieving better cooling effect.
