As a result, rubber hoses are often cut manually. To ensure that the cut length is the same, measurement is often required, which is relatively inconvenient and reduces the cutting efficiency of rubber hoses. Utility Model Content

Detailed Implementation

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Please see Figure 1-6This utility model provides a technical solution: a quantitative cutting device for producing rubber water hoses for automobile engines, including a cutting machine body 1. A cylinder 2 is fixedly connected to the surface of the cutting machine body 1, and a cutting blade 3 is fixedly connected to the output end of the cylinder 2 for cutting the pipe. A rubber water hose 9 is placed on the cutting machine body 1. First electric telescopic rods 4 are fixedly connected to both sides of the surface of the cutting machine body 1. Fixed plates 5 are fixedly connected to the output ends of the two first electric telescopic rods 4. Clamping blocks 6 are fixedly connected to the opposite sides of the two fixed plates 5. The opposite sides of the two clamping blocks 6 are V-shaped. The V-shaped clamping blocks 6 can stably clamp the rubber water hose 9, avoiding the rubber water hose 9 from shaking during cutting and ensuring the stable cutting action. Elastic padding layers are fixedly connected to the opposite sides of the two clamping blocks 6 to increase the friction between the clamping blocks 6 and the rubber water hose 9, preventing the clamping blocks 6 and the rubber water hose 9 from sliding against each other.

[0019] The inner wall of the cutting machine body 1 is slidably connected to the mounting box 12, and the inner wall of the mounting box 12 is slidably connected to the movable plate 13 with an "L" shaped cross section. The surface of the movable plate 13 is fixedly connected to the mounting plate 14, and the surface of the mounting plate 14 is provided with a connecting mechanism to lock the end of the rubber water pipe 9 located inside the cutting machine body 1, so as to further ensure the stability of the device when cutting the rubber water pipe 9.

[0020] The internal threaded connection of the cutting machine body 1 is a threaded rod 10. One end of the threaded rod 10 inside the cutting machine body 1 is rotatably connected to the surface of the mounting box 12. A scale plate 11 is fixedly connected to the surface of the mounting box 12, penetrating the surface of the cutting machine body 1. The surface of the scale plate 11 is slidably connected to the interior of the cutting machine body 1. Thus, by rotating the threaded rod 10, the operator can drive the mounting box 12 to move within the cutting machine body 1, thereby changing the position of the connecting mechanism and adjusting and limiting the distance that the rubber hose 9 extends into the cutting machine body 1. This ensures that the extension distance of each rubber hose 9 is the same, thus guaranteeing that the subsequent cutting blade 3 cuts the rubber hose 9 at the same position, achieving the effect of quantitative cutting of the rubber hose 9. At the same time, the scale plate 11 facilitates the operator's understanding of the cutting length of the rubber hose 9, making it convenient for the operator to use.

[0021] The connecting mechanism includes a motor 15 fixed to the surface of the mounting plate 14. The output shaft of the motor 15 passes through the surface of the mounting plate 14 and is rotatably connected to the interior of the mounting plate 14. The output shaft of the motor 15 is fixedly connected to a rotating disk 20. The surface of the rotating disk 20 is provided with arc-shaped grooves 21 arranged equidistantly in a circle. The arc-shaped grooves 21 are inclined. The surface of the mounting plate 14 is slidably connected to a moving rod 22 arranged equidistantly in a circle. The end of the moving rod 22 away from the mounting plate 14 slides against the inner wall of the arc-shaped groove 21. The outer surface of the rotating disk 20 is provided with inner support blocks 23 arranged equidistantly in a circle. The cross-section of the inner support block 23 is "T" shaped. The surface of the inner support block 23 is fixedly connected to the surface of the moving rod 22, so that when the moving rod 22 moves, it can synchronously drive the inner support block 23 to move.

[0022] The outer surface of the inner support block 23 is fixedly connected to a conical protrusion 24. The protrusion 24 can be inserted into the inner wall of the end of the rubber water pipe 9 inside the cutting machine body 1, thereby improving the connection strength between the end of the rubber water pipe 9 inside the cutting machine body 1 and the inner support block 23, preventing the rubber water pipe 9 from separating from the inner support block 23, and ensuring the smooth operation of the subsequent device.

[0023] The mounting plate 14 has a sliding connection inside, with a push plate 18 penetrating its surface. The push plate 18 has a U-shaped cross-section, and springs 17 are movably sleeved at both ends of the push plate 18. The two ends of the springs 17 are fixedly connected to the surfaces of the push plate 18 and the mounting plate 14, respectively, to reset the push plate 18. The surface of the mounting plate 14 is provided with two buttons 19, both of which are electrically connected to the motor 15. This allows the push plate 18 to smoothly drive the motor 15 to rotate after pressing the buttons 19, eliminating the need for manual operation and improving the convenience of using the device.

[0024] Two support rods 8 are slidably connected to the surface of the cutting machine body 1. The upper ends of the two support rods 8 are fixedly connected to the second electric telescopic rods 7. The output ends of the two second electric telescopic rods 7 are fixedly connected to the surfaces of the two clamping blocks 6 respectively, so as to drive the two clamping blocks 6 to slide against the two fixed plates 5. In order to reduce the friction between the clamping blocks 6 and the fixed plates 5, ball bearings can be set between the clamping blocks 6 and the fixed plates 5 to improve the smoothness of sliding between the clamping blocks 6 and the fixed plates 5.

[0025] The cutting machine body 1 is internally fixedly connected to a fourth electric telescopic rod 25. The output end of the fourth electric telescopic rod 25 is fixedly connected to a support plate 26 for supporting the long tube. The cutting machine body 1 is internally equipped with a feeding mechanism 27 for pushing the long tube, thereby realizing the automatic feeding of the long tube. The feeding mechanism 27 is a device such as a hydraulic rod that can perform telescopic movements. This is a conventional technical means for those skilled in the art, and therefore will not be discussed in detail here.

[0026] Working principle: When cutting the rubber hose 9, the third electric telescopic rod 16 is first activated, and the mounting box 12 in the movable plate 13 is pushed out, so that the rotating disk 20 can correspond to the subsequently inserted rubber hose 9. Then, the rubber hose 9 is inserted into the cutting machine body 1. As the rubber hose 9 is inserted, it pushes the push plate 18, so that the rotating disk 20 and the inner support block 23 are both inside the rubber hose 9. Due to the pushing of the rubber hose 9, the push plate 18 and the mounting plate 14 slide against each other, thereby stretching the spring 17. At the same time, the push plate 18 presses the button 19, thereby starting the motor 15 and driving the rotating disk 20 to rotate. Since the moving rod 22 is restricted by the mounting plate 14, it cannot rotate with the rotating disk 20. The inner wall of the arc groove 21 presses and pushes the surface of the moving rod 22, thereby driving the inner support block 23 to expand outward until it contacts the inner wall of the rubber hose 9. This allows the protrusion 24 to insert into the interior of the rubber hose 9, improving the fixation effect on the rubber hose 9. Then, the operator can activate the two first electric telescopic rods 4 to drive the two clamping blocks 6 to move relative to each other, squeezing and fixing the surface of the rubber hose 9 located outside the cutting machine body 1. Then, the operator can activate the two second electric telescopic rods 7 to retract, thereby causing the clamping blocks 6 to move the rubber hose 9. Since the end of the rubber hose 9 located inside the cutting machine body 1 is restricted by the protrusion 24 and cannot move, the device applies a certain stretch to the rubber hose 9, thereby preventing the rubber hose 9 from producing burrs or cut deformation due to elastic contraction when it is cut by the cutting blade 3. A pre-compression force is applied to the rubber hose 9, and the pre-compression force balances the rebound stress of the rubber hose 9, keeping the rubber hose 9 in a slightly stretched and stable state during the cutting process, ensuring a straight cut and improving the cutting quality of the rubber hose 9.

[0027] Then, the operator can start the cylinder 2 to drive the cutting blade 3 to descend and cut the rubber water pipe 9. After cutting, the rubber water pipe 9 located at one end outside the cutting machine body 1 is removed. Then, the motor 15 is reversed so that the protrusion 24 is no longer inserted into the rubber water pipe 9. At this time, under the elastic force of the spring 17, the push plate 18 is reset. During the reset process, the push plate 18 pushes the remaining rubber water pipe 9 and pushes it out of the cutting machine body 1, realizing the discharge of residual material.

[0028] When cutting ordinary long pipes, the third electric telescopic rod 16 is activated, causing the movable plate 13 to retract into the mounting box 12, so that the presence of the mounting plate 14 does not affect the feeding of the long pipe. Then the long pipe is placed on the support plate 26, and then the feeding mechanism 27 is activated to push the long pipe. Then the cylinder 2 is activated to complete the cutting of ordinary long pipes.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
