Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a punching device for tire production. Background Art

[0002] The process of producing rubber tires includes batching, mixing and extrusion molding. The rubber melt is formed into a rubber belt through the extrusion molding process. There are a large number of bubbles in the rubber belt. If the bubbles cannot be effectively discharged, the quality of the final tire will be greatly affected.

[0003] After searching, the announcement number CN213859642U discloses a tire tread punching device, which adopts a linked mechanical structure. Not only is the overall structure reliable, but it also greatly simplifies the process and improves work efficiency.

However, due to the differences in the cross-sectional planes of the tires, the distance between the contact roller and the positioning roller is fixed. When different tires need to be punched, multiple devices are required to complete the task, which limits its use. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 5 A punching device for tire production includes a frame 1, a hydraulic cylinder 4 is fixed to the top outer wall of the frame 1 by bolts, one end of the hydraulic rod of the hydraulic cylinder 4 passes through the frame 1 and is fixed to a connecting plate 11 by bolts, and the bottom of the connecting plate 11 is detachably connected to a steel needle rack 9 by bolts, and the steel needle rack 9 has multiple steel needles, so that it can punch multiple holes on the tread at one time and ensure that the punching depth is consistent, a positioning component is provided on one side of the frame 1, a protrusion 15 is fixed to one side of the connecting plate 11 by bolts, and two mounting grooves 16 are provided on one side of the protrusion 15, and an auxiliary roller 14 is connected to the internal rotation of the mounting groove 16, and the auxiliary roller 14 can make the protrusion 15 move smoothly along the inclined surface of the wedge block 20, a fixing component is provided on one side of the frame 1, and a plurality of telescopic rods 6 are fixed to the top inner wall of the frame 1 by bolts, and a mounting frame 5 is fixed between the plurality of telescopic rods 6 by bolts, The telescopic rod 6 can guide the mounting frame 5 so that it can move up and down stably to avoid it tilting during the movement. Springs 7 are welded on both sides of the mounting frame 5, and the springs 7 are fixed to the frame body 1. Positioning rollers 8 are rotatably connected to both sides of the mounting frame 5. Slots 10 are provided on both sides of the frame body 1, and the slots 10 are engaged with the bottom of the frame 17. The tire to be punched is inserted into the contact roller 2, and the hydraulic cylinder 4 extends and drives the connecting plate 11 to move downward. The connecting plate 11 moves to cause the protrusion 15 to move downward to squeeze the fixed component, thereby separating the fixed component from the slot 10. At this time, the mounting frame 5 loses its restriction, the spring 7 rebounds and extends, and cooperates with the gravity of the mounting frame 5 itself to cause the positioning roller 8 to move downward and contact the tire, thereby limiting the position of the tire, and then the connecting plate 11 continues to move downward to cause the steel needle frame 9 to move downward to punch the tire.

[0025] In the present invention, it should be noted that the fixing assembly includes a sliding hole 12, which is opened inside the frame 1, and a sliding tube 19 is slidably connected inside the sliding hole 12. A tension spring 18 is welded to one end of the sliding tube 19, and the tension spring 18 is fixed to the sliding hole 12. One end of the sliding tube 19 passes through the sliding hole 12 and is fixed with a clamping frame 17 by bolts. A wedge block 20 is fixed to one side of the clamping frame 17 by bolts, and the wedge block 20 is in contact with the auxiliary roller 14. Guide grooves 13 are opened on both sides of the frame 1, and the clamping frame 17 is located inside the guide groove 13. The movement of the connecting plate 11 causes the protrusion 15 to move downward and squeeze the wedge block 20, thereby causing the clamping frame 17 to drive the sliding tube 19 along the sliding hole 12. It moves outward and the tension spring 18 stretches. At this time, the bracket 17 is separated from the bracket 10. The positioning assembly includes a contact roller 2, which is rotatably connected to the inner wall of one side of the bracket 1. A motor is fixed to the outer wall of one side of the bracket 1 by bolts, and one end of the motor output shaft is fixed to the contact roller 2. The motor is started and the motor rotates to cause the contact roller 2 to drive the tire to rotate, thereby causing the steel needle rack 9 to perform multi-directional punching of the tire. A retaining ring 3 is sleeved on the outer side of the contact roller 2, and the retaining ring 3 is fixed to the bracket 1. The retaining ring 3 can limit the position of the tire placed on the contact roller 2. A avoidance groove 21 for accommodating the passage of the protrusion 15 is opened on the inner wall of one side of the bracket 1, and a handle is fixed to one side of the bracket 1 by bolts.

[0026] Working principle: when it is necessary to punch a hole in the tire, first put the tire to be punched into the contact roller 2 so that it contacts the retaining ring 3, and then start the hydraulic cylinder 4 to stretch it and drive the connecting plate 11 to move downward. The movement of the connecting plate 11 causes the protrusion 15 to move downward and squeeze the wedge block 20, thereby causing the bracket 17 to drive the slide tube 19 to move outward along the slide hole 12, and the tension spring 18 to stretch. At this time, the bracket 17 is separated from the slot 10, the mounting frame 5 loses its restriction, the spring 7 rebounds and stretches, and cooperates with the gravity of the mounting frame 5 itself to make the positioning roller 8 move downward and contact the tire, thereby limiting the position of the tire, and then the connecting plate 11 continues to move downward to make the steel needle frame 9 move downward to punch holes in the tire, start the motor, and the motor rotates to make the contact roller 2 drive the tire to rotate, thereby causing the steel needle frame 9 to punch holes in the tire in multiple directions.

[0027] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
