Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealing gasket production equipment, especially to a double engineering punching device for sealing gasket production. BACKGROUND

[0002] At present, double engineering punching refers to adopting two different punching steps to complete the punching task in the sealing gasket production process. Generally, the first engineering punching may be rough punching, mainly punching the approximate hole position on the gasket material, and the second engineering punching is fine punching based on the rough punching, further accurately processing the size and shape of the hole to meet the high-precision requirement of the sealing gasket. At present, the manual double engineering punching operation mode still exists in some production scenes. This is mainly because some small enterprises or specific trial production and small-batch production environments have few product orders and various specifications. Frequent replacement of the mold of the automatic punching equipment not only has high cost, but also consumes a lot of time and reduces production efficiency. In contrast, manual operation is more flexible and can quickly adapt to the production requirements of sealing gaskets of different specifications without investing a lot of funds in equipment purchase and mold replacement, effectively controlling production costs.

[0003] However, additional positioning operation is essential when manually performing double engineering punching. In the double engineering punching process, the position accuracy of the hole is extremely high, and the hole position deviation between the two punching steps must be controlled within a very small range to ensure the quality and use performance of the sealing gasket. When manually operating, workers mainly rely on their own experience and visual observation to place the gasket due to the lack of precise positioning auxiliary tools. However, the experience levels of different workers are uneven, and there is a large error in judging the gasket position. At the same time, long-term work can easily cause workers to become tired, and the stability and judgment of the hands decrease, making it difficult to keep the position of the placed gasket consistent each time. Moreover, during manual punching, workers hold the gasket for operation, and slight hand shaking is difficult to avoid, which further aggravates the position deviation of the gasket and causes the punching position to deviate. If no additional positioning is performed, the position of the two punchings will have a large deviation, resulting in the sealing gasket failing to meet the use requirements, a significant increase in scrap rate, and a serious impact on production efficiency and economic benefits.

[0036] The double-engine punching assembly comprises support columns 301 fixedly installed at four corners of the second base 2, an installation plate 302 is slidably sleeved on the four support columns 301, a fixed plate 303 is fixedly installed at the top ends of the four support columns 301, a hydraulic device 304 is fixedly installed on the fixed plate 303, the output end of the hydraulic device 304 is fixedly installed with the top of the installation plate 302, and punching heads 305 for double-engine punching are symmetrically installed at the bottom of the installation plate 302.

[0037] When the hydraulic device 304 works, the output end of the hydraulic device 304 pushes the installation plate 302 to slide downward on the support columns 301, so as to drive the punching heads 305 to move downward to punch the gasket, the support columns 301 play the roles of guiding and supporting, the stability of the movement of the installation plate 302 and the punching heads 305 is ensured, the punching precision is ensured, and the double-engine punching assembly can realize twice punching on the same gasket, so as to improve the production efficiency and product quality.

[0038] The four sides of the mounting plate 302 are fixedly installed with a plurality of connecting blocks 14, the bottom of each connecting block 14 is fixedly installed with an extrusion block 15, each extrusion block 15 is located directly above the adjacent limiting sheet 12, and the top of the first base 1 is provided with a plurality of extension grooves, each extension groove is located directly below the adjacent extrusion block 15.

[0039] When the mounting plate 302 moves downward for punching, the extrusion block 15 descends with the mounting plate 302 and extrudes the limiting sheet 12, triggering the positioning assembly to position the gasket, and the provision of the extension groove provides space for the descent of the extrusion block 15, avoiding collision between the extrusion block 15 and the first base 1, and ensuring normal operation of the equipment.

[0040] The implementation principle of the double-engine punching device for producing sealing gaskets in the embodiment is as follows: before use, the positioning assembly is adjusted according to the size of the gasket to be punched. The connecting rod 7 is moved to slide in the second sliding groove 6, so as to move the fixedly connected sliding block 402 in the first sliding groove 401. After the position is determined, the rotating block 8 is rotated. Since the rotating block 8 is threadedly connected with the connecting rod 7, the rotation of the rotating block 8 will cause the connecting rod 7 to be pulled, so as to extrude the sliding block 402 and the inner wall of the first sliding groove 401, and the fixation of the sliding block 402 is realized, so as to adapt to the positioning requirements of gaskets of different sizes.

[0041] After the adjustment is completed, the gasket to be punched is placed on the second base 2, and the gasket is placed between the plurality of sliding blocks 402.

[0042] Then the equipment is started, and the double-engine punching assembly starts to work. The hydraulic device 304 on the fixed plate 303 is started, the output end of the hydraulic device 304 pushes the mounting plate 302, and the mounting plate 302 slides downward on the supporting column 301. The punching heads 305 symmetrically installed at the bottom of the mounting plate 302 move downward together with the mounting plate 302, and are ready for punching operation on the gasket.

[0043] In the process of downward movement of the mounting plate 302, the extrusion blocks 15 at the bottom of the connecting blocks 14 on the four sides of the mounting plate 302 also descend. When the extrusion blocks 15 descend to contact the limiting sheets 12, the extrusion blocks 15 start to extrude the limiting sheets 12. After the limiting sheets 12 are extruded, the first pushing rod 9 is driven to move into the second base 2.

[0044] When the first push rod 9 moves, the second push rod 10 in the sliding hole at one end of the first push rod 9 slides in the sliding hole under the action of the second spring 11 and pushes the sliding block 402 connected therewith to slide in the first sliding groove 401, and the second spring 11 buffers the extrusion of the gasket, avoiding the deformation of the gasket caused by extrusion. The plurality of sliding blocks 402 extrude the gasket from different directions, so that the position adjustment and fixation of the gasket are realized, and the displacement of the gasket in the punching process is avoided.

[0045] The punching head 305 continues to move downward to perform double punching operation on the fixed gasket. In this process, the mounting plate 302 presses the push block 403 into the pressing groove, so that the push block 403 does not affect the punching.

[0046] After the punching is completed, the output end of the hydraulic device 304 is retracted, the mounting plate 302 is moved upward, the punching head 305 leaves the gasket, and the extrusion block 15 leaves the limiting piece 12. Under the elastic force of the second spring 11 and the third spring 13, the first push rod 9 and the second push rod 10 return to the initial position, and the sliding block 402 returns to the initial position under the action of the second spring 11.

[0047] The worker only needs to move the gasket to the lower side of another punching head 305, and the same operation steps and the working process of the equipment can complete the second punching work, that is, the precise punching machining, so that the double punching production is completed.

[0048] The above embodiment is only a preferred embodiment of the utility model, and cannot be used to limit the range of protection of the utility model. Any non-substantial change and replacement made by the person skilled in the art on the basis of the utility model belongs to the range of protection of the utility model.
