Description

Technical Field

[0001] This utility model belongs to the field of tooling technology for strip cutting machines, specifically a tooling for strip cutting machines. Background Technology

[0002] Tooling for strip cutting machines is a core auxiliary device, mainly used in industries such as machining, textiles, packaging, and rubber and plastics processing. It is used to position and clamp materials such as metal plates, fabrics, plastic blocks, and rubber during the strip cutting process, keeping the materials in a stable position during cutting. It provides a precise reference for the cutting operation of the strip cutting machine blades, ensures continuous strip cutting operations, meets the basic production needs of various industries for material strip processing, and helps to achieve standardized and batch processing of materials.

[0003] The clamping mechanisms of existing strip cutting machines mostly adopt a fixed pressure or manually adjustable pressure design. Their clamping parameters are difficult to flexibly adapt to the characteristics of the material to be cut, such as thickness and hardness. When processing materials of different specifications or materials, it is often necessary to manually adjust the spacing of the clamping structure, replace the appropriate clamping parts, or reset the clamping force parameters, making the operation process cumbersome. At the same time, the fixed clamping method is prone to damage due to excessive clamping of thin and soft materials, or positioning deviation due to excessive clamping of thick and hard materials, affecting the stability of processing quality. Summary of the Invention

[0004] To address the problems mentioned in the background art, this utility model provides a tooling for a strip cutting machine to solve the problem of adaptive and stable clamping of materials of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for a strip cutting machine, characterized in that it includes a tooling body, an electric positioning component, a pneumatic clamping component, and a control module. The top of the tooling body has a precision guide rail groove extending along its length. The electric positioning component includes a stepper motor, a ball screw, a positioning block, and a coupling. The stepper motor is fixedly connected to and passes through one end of the tooling body. The ball screw is arranged along the length of the guide rail groove, with one end connected to the output shaft of the stepper motor via a coupling, and the other end rotatably connected to the tooling body via a bearing seat. The positioning block and... The ball screw is threaded and the bottom of the positioning block slides with the guide rail groove. The pneumatic clamping assembly includes a miniature cylinder, a swing rod, a cylinder seat, and a pressure block. The miniature cylinder is fixed to the L-shaped cylinder seat, which is welded to the side of the positioning block. The piston rod of the miniature cylinder is hinged to one end of the swing rod, and the other end of the swing rod is detachably connected to the pressure block. The pressure block is rotatably connected to the top surface of the cylinder seat. The miniature cylinder is tilted downwards at an angle of 30°-40° to the horizontal. The control module includes a microcontroller and a power supply, and the entire control module is installed inside the tooling body.

[0006] Optionally, it also includes a sensing feedback component, which consists of a grating ruler, a pressure sensor and a photoelectric switch. The grating ruler is fixed to the side of the tooling body along the length of the guide rail groove. The reading head of the grating ruler is fixed to the positioning block. The pressure sensor is embedded in the bottom of the pressure block. The photoelectric switch is fixed to the side of the positioning block near the feed end of the tooling body. A position sensor is installed on the top of the cylinder seat.

[0007] Optionally, the micro cylinder integrates a solenoid valve, and the microcontroller is electrically connected to the stepper motor, the micro cylinder, the grating ruler, the pressure sensor, and the photoelectric switch.

[0008] Optionally, the tooling body is provided with a heat dissipation groove on its side, and a shock-absorbing pad is provided at the connection between the tooling body and the strip cutter. The shock-absorbing pad is made of nitrile rubber.

[0009] Optionally, the tooling body is provided with a feed platform that can be detachably installed on the side of the stepper motor, and the feed platform covers the stepper motor and the coupling.

[0010] Optionally, the heat dissipation groove is elongated and is correspondingly set with the control module, with no obstructions inside the groove.

[0011] Optionally, the tooling body has multiple mounting holes with stainless steel bushings evenly spaced on its back side along the left-right direction.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the micro cylinder is tilted downwards at a 30°-40° angle. When the piston rod drives the swinging pressure rod to clamp the material, the clamping force can be decomposed into a pressing force perpendicular to the material surface and a lateral force towards the positioning reference. This effectively restricts the loosening of the material in the vertical direction and counteracts the lateral thrust on the material during cutting, reducing the risk of displacement. The pressure sensor collects the pressure data after the pressure block comes into contact with the material in real time. After being fed back to the microcontroller, the air pressure is dynamically adjusted through the solenoid valve integrated in the cylinder, realizing flexible adjustment of the clamping force. It can adapt to materials of different thicknesses and hardnesses without replacing the clamping components, avoiding damage or insecure clamping caused by a fixed clamping force to materials with different characteristics, and ensuring the clamping stability during the processing of various materials. In this invention, a stepper motor drives a ball screw to move a positioning block along a precision guide rail groove. Combined with real-time position feedback from a grating ruler, this forms a closed-loop control system, enabling the positioning block to precisely stop at a preset position, providing a stable positioning reference for the clamping action. Once a photoelectric switch detects the material's arrival, the control module automatically triggers the clamping program, achieving an orderly connection between positioning and clamping actions, reducing potential errors caused by manual intervention. A position sensor monitors the position of the swing lever, ensuring accurate execution of the clamping action and further guaranteeing the synergistic effect of positioning and clamping, thus supporting the consistency of the cut strip width.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3As shown, this utility model provides a tooling for a strip cutting machine, characterized by comprising a tooling body 1, an electric positioning assembly, a pneumatic clamping assembly, and a control module. The tooling body 1 has a precision guide groove 2 extending along its length on its top. The electric positioning assembly includes a stepper motor 3, a ball screw 4, a positioning block 5, and a coupling 6. The stepper motor 3 is fixedly connected to and passes through one end of the tooling body 1. The ball screw 4 is arranged along the length of the guide groove 2, with one end connected to the output shaft of the stepper motor 3 via the coupling 6, and the other end rotatably connected to the tooling body 1 via a bearing seat 7. The positioning block 5 is threadedly engaged with the ball screw 4. The bottom of the positioning block 5 slides in conjunction with the guide rail groove 2. The pneumatic clamping assembly includes a miniature cylinder 8, a swing rod 9, a cylinder seat 10, and a pressure block 11. The miniature cylinder 8 is fixed to the L-shaped cylinder seat 10, and the cylinder seat 10 is welded to the side of the positioning block 5. The piston rod of the miniature cylinder 8 is hinged to one end of the swing rod 9, and the other end of the swing rod 9 is detachably connected to the pressure block 11. The pressure block 11 is rotatably connected to the top surface of the cylinder seat 10. The miniature cylinder 8 is tilted downwards and forms an angle of 30°-40° with the horizontal direction. The control module includes a microcontroller and a power supply. The control module is installed inside the tooling body 1.

[0016] Specifically, the clamping adaptability and stability have been optimized: the micro cylinder 8 is tilted downwards at 30°-40°, so that when the piston rod drives the swinging pressure rod 9 to clamp the material with the pressure block 11, the clamping force can be decomposed into a pressing force perpendicular to the material surface and a lateral force towards the positioning reference. This can effectively limit the loosening of the material in the vertical direction and offset the lateral thrust on the material during the cutting process, reducing the risk of displacement. The pressure sensor 13 collects the pressure data after the pressure block 11 comes into contact with the material in real time. After feeding it back to the microcontroller, the air pressure is dynamically adjusted through the solenoid valve integrated in the cylinder 8 to achieve flexible adjustment of the clamping force. It can adapt to materials of different thicknesses and hardnesses without replacing the clamping components, avoiding damage or insecure clamping caused by fixed clamping force to materials with different characteristics, and ensuring the clamping stability during the processing of various materials.

[0017] A tooling for a strip cutting machine is characterized in that it further includes a sensing feedback component, which consists of a grating ruler 12, a pressure sensor 13, and a photoelectric switch 14. The grating ruler 12 is fixedly connected to the side of the tooling body 1 along the length direction of the guide rail groove 2. The reading head of the grating ruler 12 is fixedly connected to the positioning block 5. The pressure sensor 13 is embedded in the bottom of the pressure block 11. The photoelectric switch 14 is fixedly connected to the side of the positioning block 5 near the feeding end of the tooling body 1. A position sensor 15 is installed on the top of the cylinder seat 10.

[0018] The micro cylinder 8 integrates a solenoid valve, and the microcontroller is electrically connected to the stepper motor 3, the micro cylinder 8, the grating ruler 12, the pressure sensor 13, and the photoelectric switch 14.

[0019] Specifically, the reliability of the coordinated positioning and clamping is improved: the stepper motor 3 drives the ball screw 4 to move the positioning block 5 along the precision guide rail groove 2, and forms a closed-loop control with the real-time position feedback of the grating ruler 12, so that the positioning block 5 can accurately stop at the preset position, providing a stable positioning reference for the clamping action; after the photoelectric switch 14 detects that the material is in place, the control module automatically triggers the clamping program to realize the orderly connection between positioning and clamping actions, reducing the coordination error that may be caused by manual intervention; the position sensor 15 monitors the position status of the swing pressure rod 9 to ensure the accurate execution of the clamping action, further ensuring the coordinated effect of positioning and clamping, and providing support for the consistency of the cutting width.

[0020] The tooling body 1 has a heat dissipation groove 16 on its side, and a shock-absorbing pad 17 is provided at the connection between the tooling body 1 and the strip cutter. The shock-absorbing pad 17 is made of nitrile rubber.

[0021] The tooling body 1 is provided with a feed table 18 that can be detachably installed on the side of the stepper motor 3. The feed table 18 covers the stepper motor 3 and the coupling 6.

[0022] The heat dissipation slot 16 is elongated and is set in accordance with the control module, with no obstructions inside the slot.

[0023] Multiple mounting holes with stainless steel bushings 19 are evenly opened on the back of the tooling body 1 along the left-right direction.

[0024] Specifically, the practicality of equipment use and maintenance is optimized as follows: the feeding platform 18 provides a flat feeding support surface for materials, while protecting transmission components such as the stepper motor 3 and coupling 6, preventing cutting debris and impurities from interfering with the transmission system; the heat dissipation grooves 16 on the side of the tooling body 1 are correspondingly set with the control module, which can quickly dissipate the heat generated by the electrical components during operation, maintain the stability of the component's working environment, and extend the service life of the electrical components; the nitrile rubber shock-absorbing pads 17 can buffer the vibration generated during cutting operations, reducing the impact of vibration on positioning accuracy and clamping stability; the stainless steel bushings 19 reduce wear on the tooling body 1 during installation and locking, reducing maintenance costs after long-term use; the detachable connection design of the pressure block 11 and the swing pressure rod 9 facilitates the replacement of the pressure block 11 or maintenance according to usage needs, improving the long-term use value of the tooling.

[0025] The working principle and usage process of this utility model are as follows: Before operation, the cutting width and clamping force parameters are preset by the control module. The fixture body 1 is fixed to the cutting machine through the mounting holes with stainless steel bushings 19, and the nitrile rubber shock-absorbing pads 17 buffer vibration. The operator places the material on the feeding table 18 and pushes it onto the bearing surface of the fixture body 1. After the photoelectric switch 14 detects that the material is in place, the control module starts the stepper motor 3, which drives the ball screw 4 through the coupling 6, causing the positioning block 5 to move precisely along the precision guide rail groove 2. The grating ruler 12 provides real-time feedback on the position to form a closed-loop positioning. Subsequently, the micro cylinder 8 tilts downwards by 30°-40° to drive the swing pressure rod 9, causing the pressure block 11 to clamp the material. The pressure sensor 13 detects the clamping force and dynamically adjusts the air pressure, and the position sensor 15 confirms that the clamping is in place. After the cutting machine completes the cutting, the micro cylinder 8 depressurizes and resets, the positioning block 5 returns to its initial position, and the operator removes the strip. During the cyclic operation, the heat dissipation tank 16 continuously dissipates heat for the control module.
