Description

Technical Field

[0001] The utility model relates to the technical field of tool guns, in particular to a cable tie tool gun. Background Art

[0002] When a car is running for a long time, the temperature of the car exhaust pipe will remain high. The car exhaust pipe needs to be insulated to avoid damaging other accessories. At present, the exhaust pipe insulation is mostly done by setting a heat shield outside the exhaust pipe to surround the exhaust pipe. Generally, the heat shield is connected together by welding. Under long-term high temperature and bumpy working conditions, the welding points are easy to fall off, resulting in an unstable connection between the heat shield and the exhaust pipe, and it cannot play a heat insulation role. In the prior art, the heat shield is fixed to the outer periphery of the exhaust pipe by cable ties, and the cable ties are tightened and cut with a tool gun. The tool gun relies on the upper and lower cutters to cooperate with each other. During use, firstly, because the cable ties are mostly made of stainless steel, a large amount of heat will be generated when the upper and lower cutters and the cable ties are in contact and friction. The stainless steel cable ties cause serious wear on the cutters. In addition, there is also wear between the upper and lower cutters, resulting in frequent replacement of the upper and lower cutters. Therefore, how to extend the service life of the upper and lower cutters is a more urgent problem. Utility Model Content

[0006] Preferably, the upper cutter and the telescopic end of the longitudinal cylinder are linked via a swing arm, one end of the swing arm contacts the upper cutter via contact block one, and the other end of the swing arm contacts the telescopic end of the longitudinal cylinder via contact block two.

[0007] Preferably, a cavity is formed between the upper cutter and the interior of the cutter seat, and the cavity is connected to the oil filling port, so that the lubricating oil in the oil filling port is transferred to the lower cutter during the up and down movement of the upper cutter.

[0008] Preferably, the cable tie includes a barb protrusion and a fixed end, the barb protrusion and the fixed end are respectively located at two opposite ends of the cable tie, the barb protrusion is semi-shuttle-shaped, and a gap is formed between the barb protrusion and the cable tie; the fixed end includes a fixed protrusion one and a fixed protrusion two, and a support portion is clamped between the fixed protrusion one and the fixed protrusion two.

[0009] Compared with the prior art, the utility model provides a cable tie tool gun, which has the following beneficial effects: by setting a refueling port on the housing, lubricating oil can flow into the knife seat from the refueling port to reduce the friction between the upper cutter and the lower cutter, and absorb the heat generated during the working process of the upper and lower cutters, so that the upper cutter and the lower cutter can press and cut the cable tie more smoothly, and the lubricating oil can also be guided into the gun nozzle through the pipeline, so that the cable tie can enter and exit more smoothly, improve work efficiency, and extend the service life of the upper cutter and the lower cutter. At the same time, the cooperation of the travel switch and the protrusion triggers the longitudinal cylinder, realizing a switch valve to control the sequential action of the transverse cylinder and the longitudinal cylinder, and the protrusion moves with the telescopic end of the transverse cylinder.

DETAILED DESCRIPTION

[0013] The technical scheme in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:

[0014] As shown in the figure, a cable tie tool gun is used to cut a cable tie 9 and press out a barb, including a shell 1, a knife seat 2, a transverse cylinder 3, a longitudinal cylinder 4, and a bump 8. The transverse cylinder 3 is located at the bottom of one side of the shell 1, and the switch valve 31 controls the extension and retraction of the transverse cylinder 3. The extension end of the transverse cylinder 3 is also connected to a barb mechanism 5 for hooking the cable tie 9; the cylinder body of the longitudinal cylinder 4 is located above the other side of the shell 1, and the longitudinal cylinder 4 is connected to the external air circuit through the travel switch 10. The travel switch 10 is installed in the shell 1 on one side of the cylinder body of the transverse cylinder 3. The protrusion 8 is installed on the telescopic end of the transverse cylinder 3 and can contact the travel switch 10. When the transverse cylinder 3 is retracted to its full position, the protrusion 8 touches the travel switch 10. Since the travel switch 10 is connected in series with the longitudinal cylinder 4, the longitudinal cylinder 4 receives a signal and operates after the protrusion 8 touches the travel switch 10; the tool holder 2 is connected to the oil filling port 7, and the oil filling port 7 is L-shaped, including a transverse portion 71 and an oblique portion 72. The oblique portion 72 is connected to the tool holder 2 through the transverse portion 71, and the angle formed by the transverse portion 71 and the oblique portion 72 is an obtuse angle. The knife holder 2 is located below the telescopic end of the longitudinal cylinder 4. The knife holder 2 includes an upper cutter 21 and a lower cutter 22. The upper cutter 21 is linked with the telescopic end of the longitudinal cylinder 4. The linkage is achieved by connecting the upper cutter 21 and the telescopic end of the longitudinal cylinder 4 through a swing arm 41. The middle part of the swing arm 41 is fixed on the shell 1 to form a fulcrum 42 for the swing arm 41 to swing. One end of the swing arm 41 contacts the upper cutter 21 through a contact block 1 43, and the other end of the swing arm 41 contacts the telescopic end of the longitudinal cylinder 4 through a contact block 2 44. The lower cutter 22 is mounted on the housing 1 and is located below the upper cutter 21. A cavity is formed between the upper cutter 21 and the inside of the cutter seat 2. The cavity is connected to the refueling port 7. The lubricating oil in the refueling port 7 is transferred to the lower cutter 22 during the up and down movement of the upper cutter 21. In this way, the lubricating oil can be brought to the lower cutter 22 through the up and down movement of the upper cutter 21. The upper cutter 21 and the lower cutter 22 are evenly covered with lubricating oil to ensure smoother contact between the two, reduce friction, and increase the service life of the upper cutter 21 and the lower cutter 22. The cable tie 9 includes a barb protrusion 91 and a fixed end 92. The barb protrusion 91 and the fixed end 92 are respectively located at the opposite ends of the cable tie 9. The barb protrusion 91 is semi-shuttle-shaped, and a gap is formed between the barb protrusion 91 and the cable tie 9; the fixed end 92 includes a fixed protrusion 1 94 and a fixed protrusion 2 95. A support portion 93 is clamped between the fixed protrusion 1 94 and the fixed protrusion 2 95. The gun mouth 6 is located beside the bottom of the knife seat 2, and the gun mouth 6 has a passage for the cable tie 9 to pass through in the horizontal direction of the cylinder 3.When in use, one end of the barb convex portion 91 passes through the supporting portion 93 to complete the preliminary tightening, and one end of the barb convex portion 91 is inserted into the gun nozzle 6. The barb mechanism 5 hooks the barb convex portion 91 and presses the switch valve 31. The transverse cylinder 3 retracts and drives the barb mechanism 5 to move toward the cylinder body direction of the transverse cylinder 3 to tighten the cable tie 9. After the cable tie 9 is tightened in place, the convex block 8 touches the travel switch 10. The travel switch 10 receives the in-place signal and starts the longitudinal cylinder 4. The longitudinal cylinder 4 controls the swing arm 41 to swing. During the swing of the swing arm 41, the contact block 43 presses the upper cutter 21 downward. The upper cutter 21 contacts the lower cutter 22 to cut the cable tie 9 and press out a barb, which engages with the fixed end 92 to complete the assembly; lubricating oil is regularly introduced into the refueling port 7, and the lubricating oil flows along the inclined portion 72 and the transverse portion 71 around the upper cutter 21. The upper cutter 21 supplies the lubricating oil to the lower cutter 22 during the up and down movement. The lubricating oil can not only reduce the friction between the upper cutter 21 and the lower cutter 22 to extend the service life of the cutters, but also take away the heat generated during the working process. Therefore, the design of the refueling port 7 makes the use of the tool gun more efficient and convenient.

[0015] The above embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
