Description

Technical Field

[0001] The utility model relates to the technical field of sealing strip processing, and particularly relates to a processing tool for sealing strips. Background Art

[0002] During the processing of sealing strips, cutting is required to make the sealing strips reach the required length.

[0003] An automobile sealing strip processing device disclosed in the patent with the publication number CN209440209U and the publication date of September 27, 2019, includes a processing table. On both sides of the bottom of the processing table, support columns are fixedly arranged. On one side of the middle of the support column and below the processing table, a bottom plate is fixedly arranged. A shock absorption mechanism is fixedly arranged between the processing table and the bottom plate. On the upper end of the middle of the processing table, a sealing strip fixing clamping seat is fixedly arranged.

[0004] In the prior art including the above patent, the sealing strip is limited and fixed by the sealing strip fixing clamping seat. Since the sealing strip has a certain elasticity, during the movement, a sliding friction is generated between the sealing strip and the sealing strip fixing clamping seat. Since the sealing strip is a rubber product and the surface is rough, the damping generated by the sliding friction is large, resulting in the sealing strip being stretched and deformed during the movement. After the deformation is restored, the cut length will be less than the preset length, thus affecting the accuracy of the cut length. Content of the Utility Model

[0005] The purpose of the utility model is to provide a processing tool for sealing strips, which is used to solve the technical problem that in the prior art, the sliding friction between the sealing strip and the sealing strip fixing clamping seat causes the sealing strip to be stretched and deformed during the movement, and after the deformation is restored, the cut length is less than the preset length, thus affecting the accuracy of the cut length.

[0006] In order to achieve the above purpose, the utility model provides the following technical solution: A processing tool for sealing strips, comprising:

[0007] A base, on which a cutting table is fixedly arranged;

[0008] It further includes support seats symmetrically arranged on the base, on which fixed shafts are arranged in an array, and limiting cylinders are rotatably arranged on the fixed shafts;

[0009] Among them, the two support seats are located on both sides of the cutting table.

[0010] Preferably, it further includes a spring fixedly arranged on the support seat, on which a buffer tool rest is fixedly arranged.

[0011] Preferably, it further includes oil storage cavities symmetrically opened in the support seats, in which limiting columns are fixedly arranged, and a push plate is slidably arranged on the limiting columns.

[0012] Preferably, a through hole is formed in the fixed shaft, and the fixed shaft communicates with the oil storage cavity.

[0013] Preferably, an annular groove is formed in the limiting cylinder, and the annular groove is arranged corresponding to the through hole;

[0014] An oil lubricating groove is formed in the limiting cylinder in a circumferential array and communicates with the annular groove.

[0015] Preferably, a piston cavity is formed in the support seat, and a piston plate is slidably arranged therein. An air hole communicating with the oil storage cavity is formed in the wall of the piston cavity.

[0016] Preferably, a connecting rod is fixedly arranged between the piston plate and the buffer tool rest.

[0017] In the above technical solution, a sealing strip processing tool provided by the present utility model has the following beneficial effects: through the rotatably arranged limiting cylinder, when the sealing strip moves, the limiting cylinder is driven to rotate on the fixed shaft, so that the sliding friction is converted into rolling friction, thereby reducing the frictional resistance, effectively avoiding the stretching deformation of the sealing strip caused by the frictional resistance during the movement of the sealing strip, and thus affecting the accuracy of the cutting length.

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0027] As Figures 1-5 shown, a sealing strip processing tooling includes:

[0028] A base 1, on which a cutting table 2 is fixedly arranged;

[0029] It further includes support seats 3 symmetrically arranged on the base 1, on which fixed shafts 34 are arranged in an array, and limiting cylinders 31 are rotatably arranged on the fixed shafts 34;

[0030] Among them, the two support seats 3 are located on both sides of the cutting table 2.

[0031] Specifically, when cutting and processing the sealing strip, the sealing strip is placed on the cutting table 2 and limited by the limiting cylinders 31 arranged on both sides, which is convenient for subsequent cutting.

[0032] Furthermore, a support frame 11 is fixedly arranged on the base 1, and the hydraulic rod 12 fixedly installed on the support frame 11 is started, so as to drive the cutting knife 13 fixed on the hydraulic rod 12 to cut the sealing strip.

[0033] Furthermore, after cutting is completed, the sealing strip is pulled to move and continue cutting. During the moving process, by driving the limiting cylinder 31 to rotate on the fixed shaft 34, the sliding friction is converted into rolling friction, thereby reducing the friction resistance. Effectively avoid that during the movement of the sealing strip, due to the friction resistance, the sealing strip is stretched and deformed, thereby affecting the accuracy of the cutting length.

[0034] In the above technology, through the rotatably arranged limiting cylinder 31, when the sealing strip moves, it drives the limiting cylinder 31 to rotate on the fixed shaft 34, thereby converting the sliding friction into rolling friction, thereby reducing the friction resistance. Effectively avoid that during the movement of the sealing strip, due to the friction resistance, the sealing strip is stretched and deformed, thereby affecting the accuracy of the cutting length.

[0035] As a further embodiment provided by the present utility model, it further includes a spring 32 fixedly arranged on the support seat 3, on which a buffer tool rest 33 is fixedly arranged.

[0036] Specifically, start the hydraulic rod 12 fixedly installed on the support frame 11, so as to drive the cutting knife 13 fixed on the hydraulic rod 12 to cut the sealing strip. During the downward movement of the cutting knife 13, it first contacts the buffer tool rest 33 and compresses the spring 32, thereby buffering and protecting the cutting knife 13, making the cutting knife 13 more stable during the cutting process, and thus improving the cutting effect.

[0037] As a further embodiment provided by the present utility model, it further includes an oil storage cavity 36 symmetrically opened in the support seat 3, with a limiting column 361 fixedly arranged therein, and a push plate 362 slidably arranged on the limiting column 361.

[0038] Specifically, a through hole 341 is opened on the fixed shaft 34, and the fixed shaft 34 communicates with the oil storage cavity 36. The push plate 362 is limited by the limiting block 3611, and the push plate 362 is driven to slide upward on the limiting column 361 (taking Figure 2 the shown direction as the standard), so as to push the lubricating oil arranged in the oil storage cavity 36 into the fixed shaft 34, and overflow through the through hole 341 into the gap between the fixed shaft 34 and the limiting cylinder 31, thereby lubricating between the fixed shaft 34 and the limiting cylinder 31, further reducing the friction between the fixed shaft 34 and the limiting cylinder 31, further reducing the frictional resistance, and effectively avoiding the stretching deformation of the sealing strip during the movement process.

[0039] As a further embodiment provided by the present utility model, it further includes an annular groove 311 opened in the limiting cylinder 31, and the annular groove 311 is correspondingly arranged with the through hole 341;

[0040] It further includes lubricating oil grooves 312 arranged in a circumferential array in the limiting cylinder 31, which communicate with the annular groove 311.

[0041] Specifically, the push plate 362 is driven to slide upward on the limiting column 361 (taking Figure 2 the shown direction as the standard), so as to push the lubricating oil arranged in the oil storage cavity 36 into the fixed shaft 34, and overflow through the through hole 341 into the annular groove 311, and then enter the lubricating oil grooves 312 through the annular groove 311. When the limiting cylinder 31 rotates, the surface of the fixed shaft 34 is lubricated and oiled, thereby further reducing the friction between the fixed shaft 34 and the limiting cylinder 31.

[0042] As a further embodiment provided by the present utility model, it further includes a piston cavity 37 opened in the support seat 3, with a piston plate 351 slidably arranged therein, and an air hole 371 communicating with the oil storage cavity 36 is opened on the cavity wall of the piston cavity 37.

[0043] Specifically, by driving the piston plate 351 to move downward in the piston cavity 37 (taking Figure 2Taking the shown direction as the standard), the gas in the piston chamber 37 is squeezed, and enters the oil storage chamber 36 through the air hole 371, so as to push the lubricating oil arranged in the oil storage chamber 36 into the fixed shaft 34.

[0044] As a further embodiment provided by the present utility model, it further includes a connecting rod 35 fixedly arranged between the piston plate 351 and the buffer tool rest 33.

[0045] Specifically, during cutting, the hydraulic rod 12 fixedly installed on the support frame 11 is started, so as to drive the cutting knife 13 fixed on the hydraulic rod 12 to cut the sealing strip. During the downward movement of the cutting knife 13, it first contacts the buffer tool rest 33 and squeezes the spring 32, so as to buffer and protect the cutting knife 13, so that the cutting knife 13 is more stable during the cutting process, thereby improving the cutting effect.

[0046] Furthermore, during the downward movement of the buffer tool rest 33, the piston plate 351 is pushed to move downward in the piston chamber 37 through the connecting rod 35 (taking Figure 2 the shown direction as the standard), the gas in the piston chamber 37 is squeezed, and enters the oil storage chamber 36 through the air hole 371, so as to push the lubricating oil arranged in the oil storage chamber 36 into the fixed shaft 34, without the need for an additional driving source to drive the piston plate 351 to move, thereby further simplifying the structure and saving the manufacturing cost.

[0047] Working principle: When cutting and processing the sealing strip, the sealing strip is placed on the cutting table 2 and limited by the limiting cylinders 31 arranged on both sides to facilitate subsequent cutting. The hydraulic rod 12 fixedly installed on the support frame 11 is started, so as to drive the cutting knife 13 fixed on the hydraulic rod 12 to cut the sealing strip. After cutting is completed, the sealing strip is pulled to move and continue cutting. During the movement, by driving the limiting cylinder 31 to rotate on the fixed shaft 34, the sliding friction is converted into rolling friction, thereby reducing the friction resistance. It effectively avoids the stretching and deformation of the sealing strip caused by the friction resistance during the movement of the sealing strip, thereby affecting the accuracy of the cutting length. During the downward movement of the cutting knife 13, it first contacts the buffer tool rest 33 and squeezes the spring 32, so as to buffer and protect the cutting knife 13, so that the cutting knife 13 is more stable during the cutting process, thereby improving the cutting effect. During the downward movement of the buffer tool rest 33, the piston plate 351 is pushed to move downward in the piston chamber 37 through the connecting rod 35 (taking Figure 2(subject to the indicated direction), thereby squeezing the gas in the piston chamber 37 and entering the oil storage chamber 36 through the air hole 371, thereby pushing the lubricating oil provided in the oil storage chamber 36 into the fixed shaft 34. There is no need for an additional drive source to drive the piston plate 351 to move, thereby further simplifying the structure and saving manufacturing costs. After the lubricating oil enters the fixed shaft 34, it overflows through the through hole 341 into the annular groove 311, and then enters the lubricating oil groove 312 through the annular groove 311. When the limiting cylinder 31 rotates, lubricating oil is applied to the surface of the fixed shaft 34, thereby further reducing the friction between the fixed shaft 34 and the limiting cylinder 31, further reducing the friction resistance, and effectively avoiding the stretching deformation of the sealing strip during movement.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
