Description

Technical Field

[0001] This utility model relates to the technical field of metal processing and cutting devices, and in particular to a profile cutting device with an oil-sealed metal frame. Background Technology

[0002] The oil seal metal skeleton is the core support structure of the oil seal assembly. It is usually made of cold-rolled steel plate or stainless steel plate metal profiles. Its main functions are to provide shape support for the rubber oil seal, enhance the fit and sealing between the oil seal and the equipment mounting surface, and withstand the radial and axial pressure generated during equipment operation. It is widely used in automotive engines, hydraulic systems of construction machinery, and marine transmission devices. In the production process of oil seal metal skeletons, profile cutting is a key pre-processing step. Rolls or sheets of metal profiles need to be cut into blanks of specific specifications according to the skeleton design dimensions. The cutting accuracy, operational stability, and adaptability of the profile cutting device directly determine the subsequent processing qualification rate of the oil seal metal skeleton, and thus affect the overall sealing performance and service life of the oil seal.

[0003] Early oil seal metal frame profile cutting devices were mostly mechanical cutting structures, mainly composed of a fixed cast iron frame, manual feed guide rail, ordinary high-speed steel blades, and manual clamping components. These devices had significant drawbacks: manual feed relied on operator experience to control the feed speed, which could lead to burrs on the cutting edges due to uneven feed, requiring additional grinding. Furthermore, the manual clamping force was difficult to maintain consistently, causing thin profiles to deform and thick profiles to shift during cutting. Existing devices have gradually upgraded to integrated structures, using a hydraulic drive system to replace manual feed. Hydraulic cylinders drive the cutting blade assembly to achieve uniform cutting speed, and spring-type or pneumatic cylinder-type clamping components automatically adapt to different profile thicknesses, effectively reducing... While reducing burr generation and dimensional deviation rates, existing equipment still suffers from key shortcomings such as large size, difficulty in flexible movement and operation, and complex disassembly. To ensure the operational stability of the hydraulic drive system and cutting blade assembly, existing equipment mostly adopts an integrated welded frame and lacks a modular mobile structure. This prevents flexible relocation based on the production needs of multiple workstations in the workshop, limiting its use to a single fixed area. The core components of existing equipment are rigidly connected to the frame by multiple sets of high-strength bolts, and there is a complex pipeline layout between the components. When maintenance or replacement of components is required, the pipelines must be disassembled and the fixing bolts unscrewed one by one. The entire disassembly process is time-consuming and cumbersome, and improper pipeline disassembly and assembly can lead to subsequent operational failures. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a profile cutting device for oil seal metal skeleton, which aims to improve the problems of existing equipment being bulky, difficult to move and operate flexibly, and difficult to disassemble and maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a profile cutting device for an oil-sealed metal frame, comprising a housing, a cutting mechanism provided on the inner wall of the housing, a protective mechanism provided on the front side of the inner wall of the housing, the protective mechanism being used to prevent squeezing and impact during the transport of raw materials, a dustproof block being fixedly connected to the left side of the housing, and a motor being provided on the left side of the dustproof block; The cutting mechanism includes two fixed shafts.

This connection allows the first sliding shaft 2085 and the second sliding shaft 2086 to move along the trajectory of the first sliding groove 203, thereby driving the lever 202 to rotate around the fixed shaft 201. The middle ends of the first sliding shaft 2085 and the second sliding shaft 2086 are fixedly connected to a fourth gear 2087 and a fifth gear 2088, respectively.

When the device is not in use, the front end of the slide plate 9 is closed to prevent dust.

[0022] Working principle: After motor 5 starts, its output end drives the rotating shaft 2081 to rotate, causing gear 2082 to rotate synchronously. Since gear 2082 meshes with gears 2083 and 2084 simultaneously, it drives them to rotate in opposite directions. This, in turn, causes sliding shafts 2085 and 2086 to slide within the grooves 203 of the two levers 202. The sliding of the sliding shafts forces the levers 202 to open and close about the fixed shaft 201. When the sliding shafts move closer to the fixed shaft 201, the front end of the lever 202... As the two slide shafts move closer together, the sliders 205 in the slide rail 207 slide towards each other, driving the two cutters 206 to close and complete the cutting. When the slide shaft moves away from the fixed shaft 201, the front end of the lever 202 opens, and the cutter 206 slides back to its original position with the slider 205. The meshing of gear 4 2087 and gear 5 2088 ensures that the two slide shafts move synchronously and that the cutters 206 are precisely aligned. To prevent splashing, the baffle 17 can be pulled upward along the slide plate 9 to block the upward movement. The operator can store the tools in the storage cabinet 11. Furthermore, when the device is in the waiting state, the cylinder 301 of the protective mechanism 3 is in the retracted state, and the telescopic rod 303 drives the guardrail 304 to be in a low position, which does not affect the material transportation. When the material is transported to the cutting area, the cylinder 301 is activated, and the output end pushes the telescopic rod 303 to extend upward. The limiting shaft 302 slides along the inner wall of the outer shell 1, and the guardrail 304 rises vertically. At this time, the guardrail 304 forms a horizontal barrier. If the material is deviated or squeezed due to inertia during transportation, it will first contact the guardrail 304. After the cutting is completed, the cylinder 301 drives the telescopic rod 303 to retract, and the guardrail 304 moves down to reset. The spring 305 returns to its original state under its own elastic force. When the working field of vision is insufficient, the battery box 14 can be activated through the control console 16 to drive the lighting lamp 15 to start. The heat generated inside can come into contact with the outside air through the ventilation hole 13.
