In the process of producing the rubber sleeve, in order to facilitate the subsequent use of the rubber sleeve, it is sometimes necessary to make an incision from one end of the rubber sleeve along the axial direction of the rubber sleeve. However, since the rubber sleeve is relatively soft, manual cutting is usually used to make the incision on the rubber sleeve. However, the manual cutting method is likely to cause the position of the incision to shift during the cutting process of the rubber sleeve, which will affect the yield rate of the finished product of the rubber sleeve. Therefore, there are still shortcomings and deficiencies in the prior art. Utility Model Content

[0022] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, the utility model provides a punching device for rubber sleeve production, including a workbench 5, a vertically distributed frame 1 is installed on one side of the top surface of the workbench 5, and a punching mechanism 3 with a cutter 31 that can be telescoped in the vertical direction is installed on the top of the frame 1. Specifically, the punching mechanism 3 can drive the cutter 31 to rise and fall during the telescope process; a horizontally arranged support plate 4 is also installed on the top surface of the workbench 5, and a clamping mechanism 2 located below the punching mechanism 3 is installed on the support plate 4. The clamping mechanism 2 includes a plurality of first clamping plates 21 distributed in a circular array and vertically arranged, and the first clamping plates 21 are all fixedly connected to the support plate 4, and every two adjacent first clamping plates 21 are spaced apart, and each first clamping plate 21 has a spacer outside. The support plates 4 are also fixedly connected with second clamping plates 22 which are arranged parallel to the first clamping plates 21 and are distributed at intervals, that is, every two adjacent second clamping plates 22 are arranged at intervals; and vertically distributed support blocks 23 which can cause the first clamping plates 21 and the second clamping plates 22 to deform are arranged between the multiple first clamping plates 21. Specifically, the first clamping plates 21 and the second clamping plates 22 can be made of hard plastic in the prior art, that is, when the external force disappears, the first clamping plates 21 and the second clamping plates 22 can automatically reset; the support block 23 is a truncated cone with a wide top and a narrow bottom, and a knife avoidance groove 24 opposite to the position of the cutting knife 31 is vertically opened on one side of the top surface of the support block 23, and the knife avoidance groove 24 is opposite to the gap between the two adjacent first clamping plates 21.

[0024] When in use, after the clamping mechanism 2 clamps the rubber sleeve 10, the punching mechanism 3 punches the rubber sleeve 10 to form a cut. Specifically, first, Figure 2 As shown, the rubber sleeve 10 is vertically placed in the gap between the first clamping plate 21 and the second clamping plate 22, and then the supporting block 23 is vertically inserted between the multiple first clamping plates 21, and the knife avoidance groove 24 on the supporting block 23 is located below the cutting knife 31, and the knife avoidance groove 24 is directly opposite to the gap between two adjacent first clamping plates 21. In the process of inserting the supporting block 23, the supporting block 23 can cause the first clamping plate 21 and the second clamping plate 22 to deform and expand outward to open the rubber sleeve 10. Then, when the punching mechanism 3 is extended, it can drive the cutting knife 31 to punch the rubber sleeve 10 to form an incision. Compared with the manual cutting method in the prior art, this punching method can reduce the deviation of the incision position, thereby improving the finished product yield of the rubber sleeve 10; then when the punching is completed, the supporting block 23 is taken out, at this time, the first clamping plate 21 and the second clamping plate 22 can be automatically reset, and then the rubber sleeve 10 is taken out.

[0025] Further, such as Figure 1 , Figure 2 and Figure 5 As shown, a horizontally distributed support platform 6 is rotatably connected to the top surface of the workbench 5, and the support platform 6 is transmission-connected to a stepper motor 7 installed on the workbench 5, and the stepper motor 7 is externally connected to a power supply and a start-stop switch; the support plate 4 is a circular plate, and the support plate 4 can be detachably mounted on the support platform 6 and arranged coaxially with the support platform 6, the number of the clamping mechanisms 2 is multiple groups, and the multiple groups of clamping mechanisms 2 are equidistantly distributed along the circumference of the support plate 4. Specifically, since the support plate 4 can be detachably mounted on the support platform 6, more support plates 4 can be prepared during use, and multiple groups of clamping mechanisms 2 can be installed on each support plate 4, and then before punching, The rubber sleeve 10 is clamped in advance by the clamping mechanism 2, and when punching, it is only necessary to replace the support plate 4 on the support table 6. Since multiple sets of clamping mechanisms 2 are installed on the support plate 4, the downtime of the punching mechanism 3 can be reduced to improve the punching efficiency of the rubber sleeve 10. In addition, the angle at which the stepper motor 7 can rotate each time depends on the number of clamping mechanisms 2 on the support plate 4. When in use, after starting the stepper motor 7, it can indirectly drive the support plate 4 to rotate, so that the knife avoidance groove 24 can be rotated to the bottom of the cutter 31 in turn, and the cutter 31 punches the rubber sleeve 10 in turn.

[0026] When in use, the knife avoidance groove 24 needs to face the gap between two adjacent first clamping plates 21, and it is also necessary to ensure that the knife avoidance groove 24 can be rotated to be located below the cutter 31 in sequence. Figure 2 and Figure 3As shown, an indicator arrow 9 is provided on the support plate 4 outside each set of clamping mechanisms 2. Specifically, by providing the indicator arrow 9, the position of the knife avoidance groove 24 can be easily judged.

[0027] In order to ensure the accuracy of the position of the knife-avoiding groove 24, Figures 2 to 5 As shown, a rectangular rod 25 which is arranged parallel to the support block 23 is fixedly connected to the bottom surface of the support block 23, and a plurality of rectangular through holes 41 which are equal in number to the rectangular rods 25 and opposite in position are vertically opened on the support plate 4, and the rectangular through holes 41 are adapted to the rectangular rods 25. Specifically, when in use, the knife avoidance groove 24 is first aligned with the position of the indicating arrow 9, so that the position of the knife avoidance groove 24 can be roughly judged, and then when the support block 23 is vertically inserted between the plurality of first clamping plates 21, the rectangular rod 25 is aligned with the position of the rectangular through holes 41, so that when the rectangular rod 25 is inserted into the rectangular through holes 41, the accuracy of the position of the knife avoidance groove 24 can be guaranteed.

[0028] The specific arrangement of the support plate 4 detachably mounted on the support platform 6 is as follows: Figure 1 and Figure 5 As shown, two vertically opposite positioning rods 8 are fixedly connected to the bottom surface of the support plate 4 and are plugged into the support platform 6 through the positioning rods 8. Specifically, when in use, after the positioning rods 8 are inserted into the support platform 6, the knife avoidance groove 24 on one set of the clamping mechanism 2 can be located below the cutting knife 31.

[0029] To facilitate the taking of the support plate 4, Figure 2 As shown, a groove 42 coaxially arranged with the support plate 4 is opened on the top surface of the support plate 4, and a horizontally arranged fixing plate 43 is fixedly connected to the notch position of the groove 42. Specifically, when in use, the support plate 4 can be easily taken by holding the fixing plate 43, thereby facilitating the disassembly and assembly of the support plate 4 on the support platform 6.

[0030] In order to facilitate the removal of the support block 23 from between the plurality of first clamping plates 21, Figure 2 and Figure 4 As shown, a lifting ring 26 is installed on the top surface of each supporting block 23. Specifically, when in use, the supporting block 23 can be pulled directly through the lifting ring 26 or a circular rope can be installed on the lifting ring 26, so that the supporting block 23 can be easily removed from between the multiple first clamping plates 21.

[0031] The specific arrangement of the punching mechanism 3 is as follows: Figure 1As shown, the punching mechanism 3 also includes a vertically distributed electric telescopic rod 32, the bottom end of the electric telescopic rod 32 is a telescopic end, the top end of the electric telescopic rod 32 is connected to the frame 1, and the cutter 31 is horizontally arranged and connected to the telescopic end of the electric telescopic rod 32. Specifically, the electric telescopic rod 32 can be set as an electric push rod, and the electric telescopic rod 32 is externally connected to a power supply and a start-stop switch. When in use, when the telescopic end of the electric telescopic rod 32 is in the process of extension and retraction, it can drive the cutter 31 to rise and fall, so as to punch the rubber sleeve 10 to form an incision.

[0032] In order to improve the stability of the cutter 31 during the lifting process, Figure 1 As shown, guide rods 33 which are arranged parallel to the electric telescopic rod 32 and are retractable are installed on both sides of the electric telescopic rod 32. The two ends of the guide rod 33 are respectively connected to the cutter 31 and the frame 1. Specifically, when in use, when the telescopic end of the electric telescopic rod 32 is in the process of retracting, the guide rod 33 can be retracted synchronously, which can improve the stability of the cutter 31 during the lifting process.
