An online punching machine for rubber sealing strip with adjustable punching distance

Abstract

The invention discloses a rubber sealing strip on-line punching machine capable of adjusting the punching space. The rubber sealing strip on-line punching machine comprises a strip material supportingtable and a punching head facing the supporting table. The punching head is in transmission with a driving mechanism to do circumferential movement. Each circumference of moving of the punching headis divided into a punching section close to the supporting table and a separating section away from the supporting table. The driving mechanism drives the punching head to make the linear velocity ofthe punching head at the punching section be equal to the forward velocity of a strip material on the supporting table, and the linear velocity of the punching head at the separating section be largerthan or less than the forward velocity of the strip material on the supporting table. According to the rubber sealing strip on-line punching machine capable of adjusting the punching space, the moving trajectory of the punching head is decomposed, so that the punching head has the same velocity with a rubber sealing strip at the punching section, and the punching quality is ensured, the punchinghead moves at different velocities at the separating section, adjusting of the punching space can be achieved, and requirements are met completely.

Description

technical field [0001] The invention relates to the field of punching machines for rubber sealing strips, in particular to an online punching machine for rubber sealing strips with adjustable punching distance. Background technique [0002] Strips such as rubber sealing strips need to be punched in the process, and the prior art adopts such figure 2 In the shown rubber sealing strip punching machine, the rubber sealing strip advances in a straight line on the pallet 6, and the punching head 1 above the pallet 6 is installed on the supporting rod 2 horizontally connected between the two driving wheels 3 and rotates at a constant speed. With the rotation of the drive wheel 3, the punching head 1 moves in a circular motion close to and away from the pallet 6. The punching head 1 must keep the same speed during the contact with the rubber sealing strip, so as to avoid the deformation of the punched hole, and the uniform speed The rotation determines that the spacing between two...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an online punching machine for rubber sealing strips with adjustable punching distance, which can solve the problem that the existing rubber sealing strip punching machine adopts two uniformly rotating and adjustable spacing punching heads to punch holes. Holes with different pitches lead to a large deviation between the first hole punched by the next punching head and the second hole punched by the previous punching head, and the product quality is difficult to fully meet the requirements.
