Description

Electric cable cutter

technical field

The utility model belongs to cutting equipment, in particular to an electric cable sheath electric cutter for cutting the cable sheath.

Background technique

At present, in engineering construction, many construction sites involve the processing of finished cable products, among which the cutting of the outer sheath of the cable is an important but troublesome process for construction workers. Because polyvinyl chloride plastic has good insulation, water resistance, heat resistance, sealing, corrosion resistance, relatively stable molecular structure, not easy to age, simple processing technology, and easy raw material prices, it is widely used in the processing and manufacturing of electrical products. Sheaths are also mostly made of polyvinyl chloride plastic. There are also some problems in the performance of polyvinyl chloride plastics. For example, as the temperature changes, its hardness will change greatly, especially as the cable transmission voltage gradually increases, the thickness of the cable outer sheath will also increase. Increase, the thickness of the outer sheath of the 110kv cable is much larger than the thickness of the outer sheath of the 10kv cable. When it is necessary to process the outer sheath of the cable during construction, it is not easy to cut through the outer sheath of the cable by hand under normal circumstances. If it is more difficult to cut it in winter, the phenomenon of knife breaking and hand injury often occurs. Not only is the work intensity high and the efficiency low, but it also has a great impact on the personal safety of construction workers. It not only makes the construction personnel a big headache, but also brings a lot of inconvenience to the engineering construction. ``

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

The cable sheath electric cutter shown in Figure 1, the power head 21 is connected to the power source, the power head 21 is installed on the power head bracket 20, the cutter 19 is installed on the power head 21, and the cutter 19 passes through the upper guide wheel bracket 17 Contact with the cable outer sheath. The power head support 20 is connected with the dovetail groove structure of the base plate 14 , the power head support 20 is connected with the feeding connecting block 5 , and the base plate 14 passes through the feeding connecting block 5 . The handle 1 is installed on the screw mandrel handwheel 2, and the handwheel 2 is connected with the feed screw mandrel 4 through the connecting pin 3. Feed screw mandrel 4 is connected with screw mandrel handwheel 2, and feed screw mandrel 4 is installed on the screw mandrel positioning block 8 through the knife feed coupling block 5, and screw mandrel positioning block 8 is installed on the base plate 14. Upper guide wheel support 17 is connected with base plate 14 dovetail groove structures, and upper guide wheel support 17 both sides have upper guide wheel support locating plate 11, and upper guide wheel support locating plate 11 is connected with location locking nut 10. Guide adjustment tooth bar 18 is installed on the last guide wheel support 17 and the lower guide wheel support 16. Four guide wheels 13 are installed on the upper guide wheel support 17, and guide wheels 13 are fixed on the guide wheel seat 12, and guide positioning gear 7 and compression nut 6 are housed on the guide wheel seat 12. The guide wheel seat 12 is connected with the upper guide wheel bracket 17 and the lower guide wheel bracket 16 through the axle sleeve 9, and the lower guide wheel bracket lock nut 15 is installed on the lower guide wheel bracket 16, and the lower guide wheel bracket lock nut 15 passes through the bottom plate 14 is connected with lower guide wheel support 16. 

Through the above technical solutions, combined with Fig. 1, it can be seen that the power head is rotated at high speed by the power source, and the cutting tool is driven to cut the outer sheath matrix at a speed exceeding 10,000 revolutions per minute. The power head is connected with the dovetail groove structure of the bottom plate through the power head bracket. When the screw hand wheel is turned, the screw rod drives the power head bracket to move through the knife connection block, so that the power head can reciprocate in a controlled manner, thereby accurately adjusting Feed rate, to achieve the purpose of precision machining. The method of artificially incapable of accurately controlling the construction quality is replaced by mechanization, precision, modelization, and semi-automation. The upper guide wheel bracket is also combined with the bottom plate with a dovetail groove structure, and there are positioning plates on both sides of it, which cooperate with the positioning lock nuts to control and adjust the moving range of the upper guide wheel bracket. Four guide wheels are installed on the upper guide wheel bracket, and the guide wheels are fixed on the guide wheel seat that can move axially. By installing the guide wheel seat on the guide wheel seat and adjusting the reciprocating movement of the rack, the guide positioning gear can be rotated. , and then control the guide wheel to move radially or axially. The difference between the function of the lower guide wheel bracket and the upper guide wheel bracket is that the upper and lower guide wheels can be quickly opened and pressed by the locking nut of the lower guide wheel bracket, and the cables between the brackets can be quickly converted to change the angle of the guide wheel. Drive the cable to move radially and axially, so as to cut the outer sheath radially and axially. Through the position change between the power head bracket and the upper and lower guide wheel brackets, the outer sheath of cables with different outer diameters can be cut.
