[0018] The rubber shock pad can be used as a shock absorbing material, and the rubber shock pad series products are usually manufactured by pre-pressing or stamping during the processing. After the rubber shock pad series products are stamped, the edges of the products have excess residual materials. The device can be used to trim the edges of the rubber shock pad to remove the excess residual materials.

[0019] In the structure, the adsorption plate 5 is further provided with a plurality of adsorption holes 18. The adsorption plate is internally provided with a cavity, the cavity is communicated with the adsorption holes, and the side wall of the adsorption plate 5 is further provided with a mounting hole 19 for mounting a vacuum connector. The vacuum connector is connected with a vacuum machine through a hose, and the vacuum machine is not the focus of the device, so it will not be described here.

[0020] When the device is used to trim the edges of the rubber shock pad, the rubber shock pads are placed on the adsorption plate one by one and in order according to the requirements, at this time, the excess residual materials of the rubber shock pads are exposed to the adsorption plate. The vacuum machine starts to work, and the adsorption holes generate negative pressure to adsorb the rubber shock pads. Then, the sliding seat moves towards the trimming mechanism, and after moving to the position, the excess residual materials of the rubber shock pads are located between the upper cutter and the lower cutter. Finally, the driving motor drives the lifting lead screw to rotate, the lead screw seat moves downward, the pressing plate contacts and tightly presses the rubber shock pad, the upper cutter moves downward, and the trimming work is completed under the action of the upper cutter and the lower cutter.

[0021] When the pressing plate contacts the damping rubber pad, the screw rod base continues to move downward, the pressing plate moves upward by a small distance, the spring is compressed until the pressing plate presses the damping rubber pad, and finally the upper cutter and the lower cutter complete the trimming of the excess residual material. Before the upper cutter and the lower cutter trim, the pressing plate is first used to press the damping rubber pad, so that the trimming of the damping rubber pad is more stable and the trimming effect is better.

[0022] After trimming is completed, the driving motor drives the screw rod base to move upward, the upper cutter is reset, and the pressing plate is reset under the action of the spring. During the trimming process, the sliding base can be used to slide longitudinally to change the trimming position. In the structure, the inner side of the screw rod base is slidingly installed on the inner wall of the mounting frame, so that the process of driving the screw rod base to move downward by the driving motor is more stable, and the trimming effect is further improved.

[0023] In actual situations, after trimming of one side of the damping rubber pad is completed, if trimming of the other side is required, the upper cutter is first moved upward and reset, the rotary cylinder drives the adsorption plate to rotate to the corresponding side edge, and then the trimming mechanism is used for trimming.

[0024] As a preferred structure, as shown in Figure 1 , the workbench 1 is provided with a carrier 20 and a sliding cylinder 21, the carrier 20 longitudinally slides, the sliding cylinder 21 is fixedly installed, the driving shaft of the sliding cylinder 21 is connected with the carrier 20, the carrier 20 is transversely provided with the sliding base 3, the carrier 20 is rotatably provided with a sliding screw rod 22, the sliding screw rod 22 is provided with a sliding sleeve 23, the sliding sleeve 23 is connected with the sliding base 3 through a short plate 231, and the carrier 20 is further provided with a sliding motor 24 for driving the sliding screw rod to rotate.

[0025] When the damping rubber pad is placed on the adsorption plate as required, the adsorption plate adsorbs and fixes it. First, the sliding motor drives the sliding screw rod to rotate, and the sliding sleeve drives the sliding base to move transversely to adjust the trimming position of the damping rubber pad. After adjustment is completed, the sliding cylinder drives the carrier to move longitudinally and towards the trimming mechanism. After moving into position, trimming is completed by the upper cutter and the lower cutter.

[0026] In addition, as shown in Figure 3 , the side wall of the adsorption plate 5 is provided with a sliding groove 25, a plurality of threaded holes 26 are formed in the sliding groove 25, a pair of positioning blocks 27 are slidingly arranged in the sliding groove 25, locking nuts (not shown in the drawing) are penetrated into the positioning blocks 27, and the locking nuts are screwed into the corresponding threaded holes for locking.

[0027] When the damping rubber pad is placed on the adsorption plate, the position of the damping rubber pad is adjusted, the side wall of the damping rubber pad is required to be in contact with the positioning block, and the excess residual material of the damping rubber pad is exposed to the adsorption plate. The adsorption plate adsorbs the damping rubber pad, and finally the edge cutting mechanism can be used for edge cutting action.

[0028] And the installation distance of the two positioning blocks can be adjusted to adapt to damping rubber pads of different sizes. When the installation position of the two positioning blocks is to be adjusted, the locking nut is first unscrewed, at which time the two positioning blocks can slide in the sliding groove to achieve the purpose of adjusting the installation position of the positioning blocks. After the installation position of the positioning blocks is determined, the locking nut is used to lock the positioning blocks.
