DETAILED DESCRIPTION
[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] The front guide plate is a front view of the front guide plate. Figures 1-10 As shown in the figure, a Bundy pipe push inflation machine pipe protection mechanism that can be opened comprises a rack, a pipe pressing mechanism, a guide plate and a guide plate displacement mechanism. The pipe pressing mechanism comprises a pressing hole plate seat 12, which is provided with a plurality of evenly distributed grooves along the length direction. A pressing plate 4 is fixed on each partition between the grooves by a pressing plate bolt 5. The guide plate is divided into a front guide plate 11 and a rear guide plate 13, which are respectively located on both sides of the pressing hole plate seat 12. The pressing hole plate seat 12, the front guide plate 11 and the rear guide plate 13 are all arranged on a bottom plate 15. The front guide plate 11 and the rear guide plate 13 are fixedly connected with the bottom plate 15 and are fixedly connected with a side seat 2 on each side. The pressing hole plate seat 12 is provided with a blind hole at both ends, and a guide screw 3 is arranged on the side seat 2. The front end of the guide screw 3 is inserted into the blind hole to fix the pressing hole plate seat 12 and ensure that the pressing hole plate seat 12 can move along the guide screw.
[0025] The middle shaft 6 is arranged in the pressing hole plate seat 12. A long groove is arranged on the bottom plate 15 below the middle shaft 6. The middle shaft 6 is arranged to protrude to the lower side of the bottom plate 15 through the long groove. A roller bearing 7 is arranged at the lower end of the middle shaft. The guide plate displacement mechanism comprises a moving left plate 8 and a moving right plate 9 arranged on both sides of the roller bearing. The moving left plate 8 and the moving right plate 9 are movably arranged on a base plate 10. The base plate 10 is fixed on the rack. The moving left plate 8 and the moving right plate 9 are connected together by a moving shaft below the roller bearing 7. One end of the moving shaft is fixedly connected with a push rod of a cylinder 1.
[0026] A plurality of front taper holes 17 are evenly arranged on the front guide plate 11, and a rear taper hole 16 concentric with the front taper hole 17 is arranged on the rear guide plate 13. The diameters of the taper holes of the rear taper hole 16 and the front taper hole 17 are both towards the front end of the equipment, facilitating the insertion of the copper pipe to be machined into the taper hole. The rear taper hole 16 and the front taper hole 17 are both U-shaped holes with the opening upwards.
[0027] The bottom of the U-shaped hole is a circular hole with a height same as the outer diameter of the copper pipe to be machined.
[0028] When the push rod of the air cylinder 1 is retracted, the moving left plate 8 and the moving right plate 9 are moved rightward. The moving left plate 8 pushes the roller bearing 7 to move rightward, driving the middle shaft 6 to move rightward. The hole plate 12 fixedly connected with the middle shaft moves rightward, and the pressing plate 4 on the hole plate 12 moves rightward, pressing the copper pipe 14 inserted into the U-shaped hole of the front guide plate 11 and the rear guide plate 13. When the push rod of the air cylinder 1 is pushed out, the pressing plate 4 moves leftward, releasing the copper pipe in the U-shaped hole of the front guide plate 11 and the rear guide plate 13, and the copper pipe can be taken out.
[0029] The two side seats 2 are respectively fixed on two chains conveying the copper pipe to be machined. A plurality of groups of push-expanding machine pipe protection mechanisms are arranged on the chains. The guide plate displacement mechanism is located at the front end of the pipe conveying equipment. When the copper pipe 14 is conveyed to the front end of the pipe conveying equipment, the air cylinder 1 acts on each group of push-expanding machine pipe protection mechanisms once, moving the pressing plate 4 away, releasing the copper pipe 14, and then entering the next pipe conveying process.
[0030] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
