Description

Technical Field

[0001] The invention belongs to the technical field of hardware processing, and in particular relates to a hardware pipe cutting device. Background Art

[0002] Hardware pipes are a very commonly used material in production and construction. The length of hardware pipes is usually very long at the beginning, so they need to be cut into the length required for production before use. In the prior art, people usually cut hardware pipes by hand-held cutting tools. This type of operation requires the operator to hold the cutting tool for a long time, which can easily cause fatigue to the operator and thus affect the cutting efficiency. In addition, the cutting length needs to be determined on the hardware pipe in advance for cutting, which is more troublesome.

[0003] To this end, relevant technical personnel have designed a cutting device as shown in CN110524043B. By moving the hardware tube between the front and rear side clamps and moving the cutting position to the left side of the cutting blade, the first motor and the second motor are started, so that the cutting blade can be moved to the left to cut the hardware tube. There is no need for people to hold the cutting tool to cut the hardware tube, which avoids hand soreness affecting the cutting efficiency. In addition, through the role of the support plate, the length of the hardware tube can be cut each time. Through the role of the clamping plate, the hardware tube can be further fixed to avoid the movement of the hardware tube affecting the cutting.

[0004] However, when the device is in use, it is necessary to manually loosen the clamp of the pipe when cutting the gap, move the pipe to the desired position and then clamp it again.

[0024] The embodiments of the present invention are intended to introduce and illustrate the structural composition of a metal pipe cutting device and the coordination relationship between the various components. Unless otherwise specified, the dimensions, materials and manufacturing processes of the various components in the metal pipe cutting device in the embodiments of the present invention can be selected according to specific circumstances and are not specifically limited or described herein.

[0025] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0026] Please also read Figure 1-Figure 4 , this embodiment provides a hardware pipe cutting device, including a base 1, a support base 2, a pushing mechanism 3, a driving mechanism 4, a clamping mechanism 5 and a cutting mechanism 6; The support seat 2 is fixed on the base 1. Preferably, a plurality of support limit seats are detachably provided, and the pipe fitting can be placed on the support seat 2. The cutting mechanism 6 is telescopically provided on the base 1; it should be understood that the cutting mechanism 6 telescopes toward the pipe fitting placed on the support seat 2.

[0027] The clamping mechanism 5 is slidably arranged on the base 1, and the pushing mechanism 3 is slidably arranged on the clamping mechanism 5; when the pushing mechanism 3 slides toward the cutting mechanism 6, it can first clamp the clamping mechanism 5 and then drive the clamping mechanism 5 to slide; when the pushing mechanism 3 slides away from the cutting mechanism 6, it can loosen the clamping mechanism 5 and then drive the clamping mechanism 5 to slide; specifically, one end of the pushing mechanism 3 is arranged on the clamping mechanism 5, and the other end is arranged on the base 1, and its movement process is: when the pushing mechanism 3 slides toward the cutting mechanism 6, it first drives the clamping mechanism 5 to close and clamp the pipe fitting, and then maintains the clamping state and slides toward the cutting mechanism 6; when the pushing mechanism 3 slides away from the cutting mechanism 6, it first drives the clamping mechanism 5 to loosen the pipe fitting, and then drives the clamping mechanism 5 to slide in the direction away from the cutting mechanism 6.

[0028] The sliding of the clamping mechanism 5 toward the cutting mechanism 6 can extend the cutting mechanism 6. The driving mechanism 4 is arranged on the base 1 and can intermittently slide the pushing mechanism 3 back and forth. Since the driving mechanism 4 causes the pushing mechanism 3 to move intermittently, by setting the movement frequency of the driving mechanism 4, the pushing mechanism 3 stops sliding when the sliding mechanism allows the cutting mechanism 6 to extend, giving the pipe sufficient time to maintain the clamping state and be cut by the cutting mechanism 6. It should also be understood that when the clamping mechanism 5 is away from the cutting mechanism 6, the cutting mechanism 6 can be retracted. Since the holding mechanism is driven by the pushing mechanism 3 to make a linear reciprocating motion, the distance that the pipe is driven to move each time is fixed.

[0029] In the present application, the clamping mechanism 5, under the reciprocating drive of the pushing mechanism 3, can maintain the clamping state to drive the pipe to move a fixed distance to the cutting mechanism 6, and maintain the clamping state to enable the cutting mechanism 6 to cut the pipe. Moreover, due to the reciprocating motion of the pushing mechanism 3, the pipe can be continuously cut at a fixed length, and there is no need to manually repeatedly control the clamping state during the cutting gap, thereby improving the cutting efficiency.

[0030] In other schemes, the clamping mechanism 5 includes a sliding seat 51, a clamping assembly 52, a gear 53 and an abutment plate 54; the clamping seat is slidably connected to the base 1, the clamping assembly 52 is provided with two groups opposite to each other and is slidably arranged on the clamping seat, the gear 53 is rotatably connected to the sliding seat 51, and the gear 53 can rotate to drive the two clamping assemblies 52 to move closer or farther; the pushing assembly is slidably connected to the sliding seat 51 and can drive the gear 53 to rotate; the abutment plate 54 is arranged on the sliding seat 51 and can extend the cutting mechanism 6. Specifically, a slide groove is provided on the base 1, and the sliding seat 51 is slidably connected in the slide groove. Preferably, the top surface of the sliding seat 51 is lower than the contact surface between the support seat 2 and the pipe fitting to prevent the sliding of the sliding seat 51 from accidentally driving the pipe fitting to slide.

[0031] In other embodiments, the clamping assembly 52 includes a clamping plate 521, a clamping slider 522, and a clamping rack 523; the clamping plate 521 is slidably disposed on the sliding seat 51, and is connected to the clamping rack 523 through the clamping slider 522; the sliding seat 51 is provided with an elongated hole, the clamping slider 522 is slidably connected in the elongated hole, and the clamping rack 523 is slidably connected to the clamping seat and meshed with the gear 53. It should be understood that the clamping rack 523 is always meshed with the gear 53.

[0032] In other schemes, the pushing mechanism 3 includes a pushing slider 31, a pushing rack 32 and a driven component 33; the pushing slider 31 is slidably connected to the sliding clamping mechanism 5 and connected to the pushing rack 32, and the pushing rack 32 can drive the clamping mechanism 5 to clamp or loosen; specifically, a sliding groove is provided on the sliding seat 51, and the pushing slider 31 is slidably connected in the sliding groove, and the pushing rack 32 can mesh with the gear 53 after sliding. The driven component 33 is rotatably arranged on the base 1, and can drive the pushing rack 32 to slide back and forth, and the driving mechanism 4 can intermittently drive the driven component 33 to rotate. Specifically, the pushing rack 32 slides toward the cutting mechanism 6 to make the two clamping plates 521 close to each other, and drives the sliding seat 51 to slide after the pushing slider 31 reaches the end of its stroke on the sliding seat 51.

[0033] In other embodiments, the driven assembly 33 includes a fixed frame 331, a driven shaft 332, a driven rod 333, a connecting rod 334 and a groove wheel 335; the fixed frame 331 is fixed on the base 1, the driven shaft 332 is rotatably connected to the fixed frame 331 and connected to the driven rod 333, one end of the connecting rod 334 is connected to the driven rod 333, and the other end is connected to the driving rack 32; the groove wheel 335 is coaxially fixed on the driven shaft 332, and the driving mechanism 4 can intermittently drive the groove wheel 335 to rotate. It should be understood that the driving rack 32, the connecting rod 334, the driven rod 333 and the driven shaft 332 can be approximately regarded as a crank slider mechanism.

[0034] In other embodiments, the driving mechanism 4 includes a driving motor 41, a rotating disk 42, a driving rod 43 and a protrusion 44; the driving motor 41 is fixed on the base 1, the rotating disk 42 is coaxially fixed on the output shaft of the motor, the driving rod 43 is eccentrically arranged on the rotating disk 42, and can intermittently drive the groove wheel 335 to rotate, and the protrusion 44 is coaxially fixed on the rotating disk 42, and can limit the rotation of the groove wheel 335. It should be understood that the driven shaft 332 stops rotating when the cutting mechanism 6 is extended, and the protrusion 44 can be inserted into the groove wheel 335 to limit the rotation of the groove wheel 335 before the cutting mechanism 6 cuts the pipe. Preferably, one rotation of the driving rod 43 can drive the groove wheel 335 to rotate 180°, that is, one rotation of the rotating disk 42 drives the sliding seat 51 to move from one end to the other end.

[0035] In other schemes, the cutting mechanism 6 includes a fixed seat 61, a telescopic plate 62, a cutting motor 63, a cutting plate 64 and a cylinder 65; the fixed seat 61 is fixed on the base 1, the telescopic plate 62 is arranged on the fixed seat 61, the cutting motor 63 is arranged on the telescopic plate 62, the cutting plate 64 is arranged on the output shaft of the cutting motor 63, and the cylinder 65 is arranged on the fixed seat 61 and connected to the telescopic end of the telescopic plate 62 through a connecting block; the cylinder 65 is controlled by a touch switch 66, and the abutment plate 54 can squeeze the touch switch 66. Specifically, the touch switch 66 is arranged on the base 1, and the cylinder 65 is extended when the touch switch 66 is pressed, and the cylinder 65 is retracted when the touch switch 66 is left.

[0036] In other schemes, the sliding seat 51 is detachably provided with a plurality of baffles 7, and the baffles 7 can limit the sliding distance of the pushing mechanism 3. Specifically, the baffles 7 can limit the sliding stroke of the pushing slider 31 when it slides toward the cutting mechanism 6, thereby limiting the rotation angle of the gear 53, and further limiting the distance between the two clamping plates 521, so that different baffles 7 can be installed and removed according to different pipe diameters, so that the two clamping plates 521 stop at the corresponding distance. At the same time, it should be noted that when replacing different baffles 7, the driven rods 333 or connecting rods 334 of different lengths should also be replaced, so that different pipe diameters can be cut with the same length.

[0037] In other solutions, a limiting groove is provided on the support seat 2. By providing the limiting groove, the two sides of the pipe fitting can be limited to prevent the pipe fitting from accidentally sliding.

[0038] The above-mentioned hardware pipe cutting device can continuously cut the hardware pipe while keeping it in a clamped state, without adjusting the clamping state of the pipe during the cutting interval.

[0039] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, some simple deductions or substitutions can be made without departing from the concept of the present invention.
