[0002] Rubber seals have high elasticity at room temperature, are slightly plastic, have very good mechanical strength, small hysteresis loss, low heat generation during multiple deformations, so their flex fatigue resistance is also very good, and because they are non-polar rubber, their electrical insulation performance is good. Circular rubber products are generally used for leak prevention. After the rubber parts are injection molded, there will be waste edge materials on the side, so a trimming device is needed for trimming.

[0003] The current trimming devices generally include two blades. After placing the seal on the mold base, the mold base is driven to rotate by a motor, and then by controlling the blades to descend, the two blades are respectively attached to the inner and outer sides of the seal, so as to cut off the waste edge materials. However, the existing trimming devices cannot quickly adjust the positions of the two blades and quickly replace the mold bases with different slots when dealing with seals of different sizes. Therefore, in view of the above disadvantages, the utility model proposes a trimming device for wear-resistant and stable rubber seals. Summary of the Utility Model

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 - 3 shown, it relates to a trimming device for wear-resistant and stable rubber seals, including a support platform 1 and a plurality of die holders 2. The inside of the support platform 1 is designed to be hollow, and a motor 3 is fixed inside the support platform 1. The output shaft at the top of the motor 3 passes through the top wall of the support platform 1 and is fixedly connected to a support plate 4. The upper surface of the support plate 4 is fixedly provided with a mounting assembly 5 for mounting the die holder 2. One side of the upper surface of the support platform 1 is provided with an L-shaped plate 6, and an adjusting assembly 7 for driving the movement of the L-shaped plate 6 is fixed on the upper surface of the support platform 1. The upper surface of the top end of the L-shaped plate 6 is fixedly provided with a cylinder 8, and the telescopic end at the bottom of the cylinder 8 is fixedly connected to a cross bar 9. Two sliding sleeves 10 are slidably sleeved on the surface of the cross bar 9, and blades 11 are fixedly connected to the lower surfaces of the two sliding sleeves 10 through bolts.

[0022] A positioning groove 21 for placing the seal is opened on the side of the upper surface of the die holder 2, and the sizes of the positioning grooves 21 on the upper surfaces of each die holder 2 are different.

[0023] When trimming the seal, the seal is clamped into the positioning groove 21, and the fixation of the seal can be realized. This fixation method is the same as the prior art.

[0024] In the middle of the upper surface of the die holder 2, a central groove 22 is provided, and a through groove 23 is provided at the bottom of the central groove 22. The installation component 5 includes an insertion block 51 fixed on the upper surface of the support plate 4. The insertion block 51 penetrates through the through groove 23, and grooves 52 are provided on both sides of the top end of the insertion block 51. A spring 53 is fixedly connected to the inner side wall of the groove 52, and the other end of the spring 53 is fixedly connected to a locking tooth 54. The locking tooth 54 is clamped on the upper surface of the central groove 22.

[0025] When installing each die holder 2, the through groove 23 at the bottom of the die holder 2 is squeezed downward along the insertion block 51, so that the insertion block 51 passes through the through groove 23. During this process, the locking tooth 54 will first be squeezed back into the groove 52, and at this time the spring 53 is squeezed. When the locking tooth 54 passes through the through groove 23, the spring 53 pops out the locking tooth 54, so that the locking tooth 54 is stuck on the inner bottom wall of the central groove 22.

[0026] The adjusting component 7 includes a base 71 fixed on the upper surface of the support table 1. The inside of the base 71 is hollow, and a strip-shaped opening 72 is provided on the top wall of the base 71. A sliding block 73 is slidably connected inside the strip-shaped opening 72. A lead screw 74 is rotatably connected inside the base 71 through a bearing. The lead screw 74 penetrates through the sliding block 73 and is threadedly connected to the sliding block 73. The top end of the sliding block 73 is fixedly connected to the lower surface of the L-shaped plate 6.

[0027] In this embodiment, a knob is fixed at one end of the lead screw 74 outside the base 71. After driving the lead screw 74 to rotate by turning the knob, the lead screw 74 can drive the sliding block 73 to move along the strip-shaped opening 72, thereby driving the L-shaped plate 6 to move, and thus changing the initial positions of the cross bar 9 and the blade 11.

[0028] The top wall of the sliding sleeve 10 penetrates and is threadedly connected with a locking bolt 13. When trimming seals of different sizes, the sliding sleeve 10 can be moved along the cross bar 9, so as to adjust the position of the blade 11, so that when the blade 11 descends, the two blades 11 just fit with the inner side and the outer side of the seal respectively. Finally, tighten the locking bolt 13 to fix the sliding sleeve 10.

[0029] Scale lines 12 are provided on the surface of the cross bar 9. The scale lines 12 can be used as a reference when moving the sliding sleeve 10.

[0030] Working principle: First, replace the die holder 2 according to the seal to be trimmed, and adjust the positions of the two blades 11. Then, clamp the seal in the positioning groove 21 at the top of the die holder 2. Next, start the motor 3 to drive the support plate 4 and the die holder 2 to rotate at high speed. Then, start the cylinder 8 to extend, so as to drive the cross bar 9 and the two blades 11 to descend, and use the two blades 11 to cut off the waste edges of the outer circle and the inner circle of the seal respectively.
