Description

Technical Field

[0001] This utility model relates to a screw support for the front bearing of a punch press crankshaft, belonging to the technical field of stamping equipment. Background Technology

[0002] Punch presses are widely used in the automotive, electronics, electrical appliance, hardware, and building materials industries. In automobile manufacturing, they are used to stamp body parts; in the electronics industry, they can stamp and form the metal casings of electronic components; and in hardware processing, they can produce standard parts such as nuts and bolts of various specifications.

[0003] Punch presses experience significant impact and vibration during use, which can damage various components over time. They are particularly prone to causing the crankshaft front bearing screw to break, posing a potential hazard. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a screw bracket for the front bearing of a punch press crankshaft, thereby solving the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a screw support for the front bearing of a punch press crankshaft, wherein a crankshaft fixing cover plate is connected to one side of the front bearing of the punch press crankshaft by a plurality of cover plate fixing screws, a punch press crossbeam is provided on the side of the punch press located below the crankshaft fixing cover plate, and the screw support is disposed between the punch press crossbeam and the crankshaft fixing cover plate; the screw support includes a screw and a nut located on the screw; the end of the screw abuts against one side of the punch press crossbeam; the nut located on the other side of the screw rests on the lower end of the crankshaft fixing cover plate.

[0006] Furthermore, two sets of screw brackets are provided, and their installation positions are close to the lower part of the cover plate fixing screws.

[0007] Furthermore, the screw support on the same side has two nuts, one above the other, with an elastic element between the lower nut and the screw.

[0008] Furthermore, the elastic element is a spring, one end of which is connected to the nut and the other end of which is connected to the inner end of the screw.

[0009] The beneficial effects of this utility model are: 1) Enhanced stability: By setting a screw bracket between the punch press beam and the crankshaft fixing cover plate, the front bearing of the crankshaft can be effectively fixed, reducing loosening and damage caused by impact and vibration, thereby extending the service life of the equipment.

[0010] 2) Reduced impact and vibration transmission: The design of the screw support effectively disperses the impact force generated during the operation of the punch press. In particular, by setting up a combination of multiple screws and nuts, the structure's seismic resistance is improved, and the impact on the crankshaft and other important components is reduced.

[0011] 3) Improved maintainability and reliability: The optimized structural design makes maintenance easier, allowing users to more conveniently inspect and replace parts, thus improving the overall reliability of the equipment and reducing downtime and maintenance costs caused by component damage.

[0012] 4) Application of elastic elements: Setting elastic elements (such as springs) on the screw support can further absorb impact energy, reduce the direct impact of impact force on the nut, improve the bonding strength between the nut and the screw, and prevent the nut from loosening and breaking.

[0013] 5) Flexibility of multi-group design: The dual-group design of the screw bracket and the installation position close to the cover plate fixing screw can provide a more uniform distribution of support force, further enhancing the stability and impact resistance of the structure, and adapting to the needs of different models and specifications of punch presses.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0018] like Figure 1As shown, a screw bracket for a front bearing of a punch press crankshaft is provided. The front bearing of the punch press crankshaft is connected to a crankshaft fixing cover plate 3 by multiple cover plate fixing screws 01. A punch press crossbeam 4 is provided on the punch press side below the crankshaft fixing cover plate 3. The screw bracket is disposed between the punch press crossbeam 4 and the crankshaft fixing cover plate 3. The screw bracket includes a screw 1 and a nut 2 located on the screw 1. The end of the screw 1 abuts against one side of the punch press crossbeam 4. The nut 2 located on the other side of the screw 1 rests against the lower end of the crankshaft fixing cover plate 3.

[0019] In this preferred embodiment, two sets of screw brackets are provided, and their installation positions are close to the lower position of the cover plate fixing screw 01.

[0020] In this preferred embodiment, there are two nuts 2 on the same side of the screw support, one above the other, and an elastic element 5 is provided between the lower nut 2 and the screw 1.
