Description

Technical Field

[0001] The present application relates to the technical field of sealing strip processing, and in particular to an integrated device for automatically punching buckle holes and precisely cutting sealing strips. Background Art

[0002] Automobile sealing strips play a vital role in automobile manufacturing. They are mainly used to fill the gaps between car body parts and have functions such as shock absorption, waterproofing, dustproofing, sound insulation and decoration. In order to make the sealing strip fit tightly with the car sheet metal, it is usually necessary to punch holes on the sealing strip and install buckles or nails.

[0003] Most of the existing sealing strip punching equipment uses a pneumatic drill group for punching operations, such as the Chinese patent application "A multi-hole sealing strip punching equipment", application number: CN202222949114.3, which discloses a frame, two or more X-axis slide cylinders are fixedly installed on the top of the frame, a lower beam is fixedly connected to the slide of the two or more X-axis slide cylinders, a part mold is fixedly connected to the lower beam, a part placement groove is provided on the part mold, a mounting frame is fixedly installed on the top of the frame and on one side of the part mold, two or more Y-axis slide cylinders are fixedly installed on the mounting frame, an upper beam is fixedly connected to the slide of the two or more Y-axis slide cylinders, a left pneumatic drill group and a right pneumatic drill group are fixedly installed on the left and right ends of the upper beam, a PLC control cabinet and an air bag are fixedly installed in the frame, and a controller is fixedly installed on the front side of the frame. The utility model can greatly improve the punching efficiency of the sealing strip, reduce the labor intensity of workers, save labor costs, and reduce safety hazards.

[0004] However, the above equipment has some obvious shortcomings. The position structure of the air drill group in the existing equipment is fixed, which means that the equipment can only process sealing strips of specific models or specifications, and lacks universality. The limitations of this special equipment require manufacturers to equip different models of sealing strips with different punching equipment, which increases the purchase and maintenance costs of the equipment. At the same time, since the equipment cannot be flexibly adjusted, the flexibility of the production line is also limited, making it difficult to adapt to the production needs of multiple varieties and small batches. There is an urgent need for a sealing strip punching equipment that is universal and can be flexibly adjusted to reduce production costs, improve processing efficiency and ensure product quality. Summary of the invention

[0005] The technical problem to be solved by the present application is to provide an integrated device for automatic punching and precision cutting of sealing strips, which can flexibly adjust the position of the drilling group, adapt to the drilling processing of sealing strips of different specifications, have universal applicability, and effectively reduce production costs.

[0006] The technical solution adopted in the present application is: an integrated device for automatic punching and cutting of sealing strips, comprising a frame, the frame comprising a table top and a back frame vertically set up on the table top, the back frame is provided with a transverse slide rail, a plurality of mounting frames are movably mounted on the slide rail, and a drilling member is detachably mounted on the mounting frame, A fixed tooling module is detachably installed on the table top, and the sealing strip to be processed is installed on the fixed tooling module. The fixed tooling module includes a cutting knife group, a rear block, and a front pressure block connected to a power device. The top surface of the rear block is provided with a groove for accommodating the sealing strip. The front pressure block moves to confine the sealing strip in the groove, and the cutting knife group passes through the front pressure block and the rear block to act on the sealing strip.

[0007] Compared with the prior art, the advantages of the present application are that, firstly, the transverse slide rails and the movable mounting frame provided on the back frame form a two-dimensional adjustable system, and the transverse position of the drilling member can be flexibly adjusted by sliding the mounting frame, thus breaking through the limitations of the traditional fixed air drill group. Specifically, a plurality of mounting frames are movably installed on the slide rails, and the drilling member is detachably installed on the mounting frame. Then, the present application can set the mounting frame at the corresponding position according to the position where the sealing strip needs to be punched, and then install the drilling member on the mounting frame, which has higher flexibility and better universality, and effectively reduces the production and processing cost of the sealing strip.

[0008] Secondly, the fixed tooling module designed in this application adopts a modular quick-change design, which realizes rapid replacement through a standardized structure and supports the clamping of sealing strips with different cross-sectional shapes. Combined with the dynamic pressure compensation function of the front pressure block, the problem of material rebound during cutting is effectively avoided. This application integrates the cutting knife group into the fixed tooling to make the punching and fine cutting processes more accurate. And completing the punching process and the cutting process at the same time also effectively improves the processing efficiency of the sealing strip.

[0009] In some embodiments of the present application, the fixed tooling module includes a base plate, which is detachably mounted on a table top, and the cutting knife group, rear stop block, and front pressure block are all mounted on the base plate; the bottom surface of the sealing strip to be processed is fitted with the groove wall surface of the rear stop block, and the front side surface of the sealing strip to be processed is fitted with the rear side surface of the front pressure block.

[0010] This application designs a substrate as a carrier for the fixed tooling module. The standardized connection structure can be used to quickly replace the fixed tooling module, thereby adapting to different sealing strip models, significantly improving equipment utilization, and reducing processing costs. The two-way limit design of the groove and the pressure block ensures the stability of the sealing strip after clamping, especially for the stable processing of elastic sealing strips, while also effectively avoiding cutting rebound. Integrating the cutting and clamping functions into a single substrate reduces multi-station transmission errors and improves the coordinated accuracy of the punching and cutting processes.

[0011] In some embodiments of the present application, cutting tool groups are provided at both ends and the middle of the fixed tooling module, and the cutting tool group includes a cutting tool, a tool holder and a dual-axis cylinder.

The dual-axis cylinder provides symmetrical driving force to avoid the tool deflection caused by unilateral pressure, and the cutting surface is smooth, meeting the high surface quality requirements of automotive sealing strips. Most sealing strips are EPDM rubber or TPV elastomer, and the elasticity of the material easily causes the incision to rebound and deform. The blade set parallel to the top surface of the sealing strip effectively reduces tensile deformation and makes the incision smoother.

[0014] In some embodiments of the present application, a pad is provided above the rear block, the bottom surface of the pad is parallel to the blade of the cutting tool, the pad corresponds to the cutting tool one by one, and the cutting tool cuts the sealing strip and contacts the bottom surface of the pad.
