Description

Technical Field

[0001] This utility model relates to the field of bushing processing technology, and more specifically, to a blank cutting device for bushing processing. Background Technology

[0002] A bushing, also known as a sleeve or sliding bearing, is a mechanical component, usually cylindrical in shape, installed between a shaft and a bearing housing. Its core function is to reduce friction, support rotating or reciprocating shafts, and protect the shaft and housing bore from wear. Based on the material, it can be divided into metals (such as copper and steel), non-metals (such as nylon and PTFE), and composite materials. It is widely used in automobiles, industrial machinery, molds, and various applications requiring low precision and high load support. During the bushing processing, cutting equipment is needed to cut the long tube blank into the specified size.

[0003] For example, Chinese Patent Publication No. CN202023005060.2 discloses a cutting device for optical element blanks, comprising a worktable, a storage cabinet, a fixed plate, a guide rail, a crossbeam, a housing, and a blade. Two columns are symmetrically arranged on the central axis of both sides of the upper surface of the worktable, and a crossbeam is fixed to each column. The housing moves on the guide rail via a chain. A blade is fixed to the bottom of the housing, and a baffle is provided on one side of the blade. The upper end of the baffle is fixed to the side of the housing. The blade is fixed to a rotating shaft, one end of which is mounted on a bracket via a bushing. The other end of the rotating shaft is mounted coaxially with pulley B via a bushing. Pulley B and pulley A rotate coaxially via a belt, and one end of pulley A is mounted on a fixed column. This cutting device can cut automatically without manual movement of the blank, reducing the risk of injury to workers during blank cutting and improving cutting efficiency.

[0004] However, the cutting equipment commonly used in the industry currently consists of a frame, a clamping mechanism (such as a three-jaw chuck), and a cutting mechanism driven by hydraulics or a motor. However, such existing equipment has obvious defects in actual use: First, during high-speed cutting, due to the lack of an effective and reliable sealed protective structure, the high-temperature and high-speed chips generated are very easy to splash into the operating area, which not only pollutes the working environment but also poses a direct threat to the safety of operators; Second, the splashed chips, especially ferromagnetic metal chips, usually fall around the equipment and on the ground, which is difficult to collect efficiently and cannot achieve preliminary classification of iron chips and non-iron chips, resulting in cumbersome and costly subsequent recycling and processing procedures, as well as safety hazards. Utility Model Content

[0005] The main objective of this invention is to provide a blank cutting device for bushing processing, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a blank cutting device for bushing processing, comprising a frame, wherein a three-jaw chuck for clamping workpieces and a protective shell are provided on the frame, the protective shell covers the cutting area on one side of the three-jaw chuck, and through slots for the blank to pass through are correspondingly opened on the two side walls of the protective shell, a sliding groove and a first groove are opened on the protective shell, the sliding groove is arranged around the first groove, a telescopic baffle is slidably arranged in the sliding groove, and a plurality of magnets for adsorbing ferromagnetic chips are inclinedly arranged on the inner wall of the bottom surface of the first groove, and the bottom surface of the sliding groove and the first groove both penetrate the protective shell, a second groove is provided on the frame directly below the protective shell, a chip collection box for collecting chips is provided in the second groove, and a cutting execution mechanism for cutting the workpiece is also provided on the frame.

[0007] Preferably, the cutting actuator includes a hydraulic rod fixed to the frame and a blade holder driven by the hydraulic rod, with the cutter mounted on the blade holder.

[0008] Preferably, the cutting actuator further includes a motor fixed to one side of the blade holder, and the cutter is rotatably mounted on the blade holder and driven to rotate by the motor.

[0009] Preferably, the telescopic baffle includes a baffle body, a spring is fixedly installed on the side of the baffle body away from the knife holder, and the other end of the spring is fixedly installed in the slide groove.

[0010] Preferably, a guide groove is provided on the side of the baffle body away from the knife holder, and a guide column is slidably disposed in the guide groove.

[0011] Preferably, the guide slide is fixedly installed in the slide groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) This utility model, through the linkage of the blade holder and the telescopic baffle, dynamically forms a semi-enclosed space that is only open downwards during cutting, effectively confining the chips generated during cutting within this space. The ferromagnetic chips are then adsorbed and separated by the tilted magnet and finally fall into the chip collection box, achieving effective protection against chip splashing and automatic classification and recycling of ferromagnetic chips, thus improving operational safety and material recycling efficiency.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2 As shown, a blank cutting device for bushing processing includes a frame 1. The frame 1 is provided with a three-jaw chuck 3 for clamping the workpiece and a protective shell 4. The protective shell 4 covers the cutting area on one side of the three-jaw chuck 3. Through grooves 9 for the blank to pass through are correspondingly opened on the two side walls of the protective shell 4. The protective shell 4 has a sliding groove 5 and a first groove 6, with the sliding groove 5 surrounding the first groove 6. A telescopic baffle 7 is slidably arranged in the sliding groove 5. Several magnets 8 for adsorbing ferromagnetic chips are inclinedly arranged on the inner wall of the bottom surface of the first groove 6. The bottom surface of both the sliding groove 5 and the first groove 6 penetrates the protective shell 4. A second groove 10 is provided on the frame 1 directly below the protective shell 4. A chip collection box 11 for collecting chips is provided in the second groove 10. The frame 1 is also provided with a cutting execution mechanism for cutting the workpiece.

[0020] The cutting actuator includes a hydraulic rod 2 fixed on the frame 1 and a blade holder 12 driven by the hydraulic rod 2, and the cutter 13 is mounted on the blade holder 12;

[0021] The cutting actuator also includes a motor 14 fixed to one side of the blade holder 12, and the cutter 13 is rotatably mounted on the blade holder 12 and driven to rotate by the motor 14.

[0022] like Figure 3As shown, in another embodiment of the present invention, the telescopic baffle 7 includes a baffle body 701, a spring 703 is fixedly installed on the side of the baffle body 701 away from the knife holder 12, and the other end of the spring 703 is fixedly installed in the slide groove 5.

[0023] The baffle body 701 is also provided with a guide groove 702 on the side away from the knife holder 12, and a guide slide post 704 is slidably disposed in the guide groove 702.

[0024] When the cutter holder 12 feeds towards the blank, it first contacts and pushes the baffle body 701, causing the baffle body 701 to slide inward along the slide groove 5. At this time, the spring 703, which is fixedly installed between the baffle body 701 and the slide groove 5, undergoes compression deformation. During this process, the guide slide groove 702 set on the back of the baffle body 701 slides precisely along the guide slide post 704 fixedly installed in the slide groove 5, ensuring that the baffle body 701 always maintains a straight line movement without deflection. When the cutter holder 12 retracts after the cutting is completed, the compressed spring 703 releases its elastic potential energy, pushing the baffle body 701 to accurately return to the initial position along the guide slide post 704, preparing for the next cutting operation.

[0025] Working principle of a blank cutting device for bushing processing:

[0026] In use, the bushing blank is first inserted through the through groove 9 on the side wall of the protective shell 4 and clamped and fixed by the three-jaw chuck 3. After the blank is fixed, the hydraulic rod 2 pushes the tool holder 12 and the cutter 13 to feed towards the blank. During this process, the tool holder 12 first contacts and pushes the baffle body 701 of the telescopic baffle 7, causing it to slide along the slide groove 5 and compress the spring 703 inward. At this time, the tool holder 12, the baffle body 701 and the protective shell 4 together form a dynamic semi-enclosed cutting space that is only open to the chip collection box 11 from below. Subsequently, the cutter 13 contacts the blank and performs cutting under the drive of the motor 14. The generated chips are effectively confined within this dynamic space and finally fall into the chip collection box 11 after being attracted and separated by the magnet 8 on the inclined inner wall of the slide groove 5 and the first groove 6 through the bottom surface. This effectively prevents chips from splashing into the operating area and greatly improves the safety of operation. At the same time, it actively attracts and separates ferromagnetic chips, realizing the initial automatic classification and efficient recycling of chips.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
