Description

Technical Field

[0001] This utility model relates to the field of sealing strip punching technology, and in particular to an online punching device for automotive sealing strips. Background Technology

[0002] With the rapid development of my country's automobile industry, the automotive sealing components manufacturing industry is increasingly becoming an important part of the automotive industry. Sealing strips are one of the most important components of a car, and their sealing performance directly affects the safety and ride comfort of the vehicle.

[0003] During the production process of automotive sealing strips, the produced long strips of rubber need to be cut, and the cutting length of the sealing strip is determined according to the model of the sealing strip. Currently, most automotive sealing strips are cut by directly feeding the produced long strips of rubber onto the cutting table.

[0004] For example, Chinese patent application CN206780544U, entitled "Automotive Door Sealing Strip End Punching Device," discloses a device comprising: a bevel cutter, an upper die, and a lower die. The bevel cutter is driven by a telescopic mechanism, which is located at the top of an inclined frame and its movable end is connected to the upper die via an elastic element. The inclination angle of the bevel cutter is consistent with the angle of the bevel at the end of the sealing strip. A sealing strip channel is provided between the upper die and the lower die, and the sealing strip channel is located along the stroke of the bevel cutter. This solution uses a telescopic mechanism located at the top of the inclined frame to drive the bevel cutter to move up and down in the inclined direction. At the same time, the telescopic mechanism drives the upper die to move up and down relative to the lower die via an elastic element, and the bevel cutter punches the sealing strip in the sealing strip channel.

[0005] In the aforementioned process of punching automotive sealing strips, the formed sealing strips need to be transported to the punching device manually or by a transfer device before they can be punched. Furthermore, manual assistance is required for both the punching process and the loading and unloading of the formed sealing strips. In the process of mass production of sealing strips, this method can easily lead to a discontinuous production cycle, resulting in low processing efficiency for the sealing strips.

The follower belt 35 is cyclic, and its winding is shown in the figure. A portion of the follower belt 35 is located between the traction unit 5 and the speed measuring component 2. Then, by the rotation of the follower roller 34, the follower belt 35 is changed to be conveyed from below the horizontal transfer unit 4. After passing around the horizontal transfer unit 4, the follower belt 35 reaches the same horizontal height as the discharge port of the second punching device 42 by the rotation of the follower roller 34. The purpose of this arrangement of the follower belt 35 is to provide power between the traction unit 5 and the speed measuring component 2 to ensure that the sealing strip is conveyed into the traction unit 5. The traction unit 5 then conveys the sealing strip to the first punching device 41, where a section of the sealing strip is cut off from the whole. The first punching device 41 simultaneously punches out the required angle at one end of the sealing strip. The cut sealing strip is then pushed by the subsequent sealing strip and fed into the sealing strip carrying assembly 6 between the first punching device 41 and the second punching device 42. It then enters the second punching device 42, which punches out the other end of the sealing strip to achieve the required punching angle.

The push rod 916 has a protrusion 919 and a recess 920 on the side opposite to the clamping block 917. The protrusion 919 and the recess 920 are connected by an inclined surface. When the clamping drive cylinder 913 drives the protrusion 919 to contact the clamping block 917, the clamping block 917 clamps the sealing strip. When the clamping drive cylinder 913 drives the recess 920 to contact the clamping block 917, the clamping block 917 releases the sealing strip. The clamping block 917 has a through hole, and the push rod 916 passes through the through hole. When the push rod is driven up and down by the clamping drive cylinder 913, the protrusion 919 and the concave part 920 respectively contact the inner wall of the through hole on the clamping block 917. When the protrusion 919 extends into the through hole, it pushes the clamping block 917 towards one side of the sealing strip, so that the clamping block 917 is pressed against the side wall of the sealing strip. At the same time, the spring 918 is compressed. When the concave part 920 extends into the through hole, it loses the push on the clamping block 917. Under the elastic restoring force of the spring 918, the clamping block 917 moves away from the sealing strip, thereby releasing the sealing strip.

[0035] In the above structure, the frame 901 is provided with an upper positioning component 921 and a lower positioning component 922, which are arranged vertically opposite each other, and a sealing strip is provided between the upper positioning component 921 and the lower positioning component 922. The lower positioning component 922 includes a lower base plate 923, a lower base 924, and a lower positioning block 925. The lower base plate 923 is fixedly connected to the frame 901, the lower base 924 is disposed on the lower base plate 923, and the lower positioning block 925 is disposed on the lower base 924. The lower positioning block 925 is used for positioning the sealing strip. The upper end face of the lower positioning block 925 is set as a contoured groove structure with the same shape as the sealing strip, so that the sealing strip can be stably placed on the lower positioning block 925. The upper positioning component 921 includes an upper top plate 926, an upper seat 927, and an upper positioning block 928. The upper top plate 926 is fixedly connected to the frame 901. The upper seat 927 is positioned above the lower base 924. The upper positioning block 928 is mounted on the upper seat 927. The sealing strip is positioned between the upper positioning block 928 and the lower positioning block 925. The lower end face of the upper positioning block 928 is configured as a contoured groove structure with the same shape as the sealing strip, which can stably position the sealing strip between the upper positioning block 928 and the lower positioning block 925. The upper positioning block 928 and the lower positioning block 925 position the sealing strip from both above and below. First, the sealing strip is fixed in place. Then, through the action of the clamping mechanism 903, two clamping blocks 917 clamp the sealing strip from both sides, thereby stably fixing the sealing strip and preventing it from shifting during the punching process. In addition, the sealing strip passes through the upper positioning block 928, the lower positioning block 925 and the two clamping blocks 917, which form a contour cavity that matches its own shape. This can prevent deformation caused by clamping while clamping the sealing strip, and ensure the accuracy of the sealing strip cutting.
