Description

Technical Field

[0001] This utility model relates to the field of metal cutting technology, and in particular to a precision edge-sealing device for metal products. Background Technology

[0002] Currently, most metal products are cut using ordinary cutting machines, which is often not precise enough. For edge trimming operations requiring higher precision, wire electrical discharge machining (EDM) can be used.

[0003] Wire EDM machines use a continuously moving, very fine metal wire (usually brass or galvanized wire) as an electrode. The metal material is removed by utilizing the localized, instantaneous high temperature generated by pulsed spark discharge between the tool electrode (wire) and the workpiece. Wire EDM can achieve micron-level precision, and the cut metal surface has a good finish without workpiece deformation.

[0004] Although the principle of wire EDM is not complex, wire EDM machines, in addition to the wire cutting itself, often require a CNC system. This necessitates pre-programming the cutting path and controlling the movement of the wire guide nozzle in the XY and UV directions according to the programmed path to ultimately cut the metal product. This not only complicates operation but, more importantly, leads to high costs for wire EDM machines, impacting business profitability.

[0005] For some regular edge cutting operations, such as cutting straight edges, bevels, and arc edges, there is no need for the complex path of the guide nozzle. Therefore, for wire cutting of such workpieces, the complex CNC system and guide nozzle motion drive mechanism can be omitted to reduce costs and increase efficiency. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a precision edge-sealing device for metal products, so as to solve the technical problem that ordinary cutting machines in the prior art cannot meet the precision requirements and the cost of wire cutting machine tools is too high.

[0007] To achieve the above objectives, this utility model provides a precision edge-cutting device for metal products, including a wire cutting machine for driving the continuous movement of a metal wire, and the precision edge-cutting device further includes: A movable support is provided in front of the wire cutting machine, the movable support is movably connected to the base, and the base is fixedly connected to the front side of the wire cutting machine; A clamping assembly and a driving mechanism are provided on a movable support. The clamping assembly is used to clamp and fix the metal workpiece, and the driving mechanism is used to drive the metal workpiece to rotate in order to cooperate with the wire cutting machine to complete the edge cutting.

[0008] Furthermore, the base is provided with slide rails on both sides, and the movable bracket is slidably connected to the base via the slide rails.

[0009] Furthermore, the clamping assembly includes a positioning clamp and a rotating clamp, which clamp and fix the metal workpiece from below and above, respectively, and the positioning clamp is fixedly connected to the output shaft of the drive mechanism.

[0010] Furthermore, a cylinder is provided above the positioning clamp, and the rotating clamp is rotatably connected to the output shaft of the cylinder.

[0011] Furthermore, the drive mechanism is fixedly installed at the bottom of the movable bracket, the cylinder is fixedly installed at the top of the movable bracket, and the drive mechanism is a servo motor.

[0012] Furthermore, the wire cutting machine is provided with several working fluid outlets below the wire guide nozzle, and the connection between the base and the wire cutting machine is provided with several working fluid return ports, which are located between the slide rails on both sides.

[0013] Furthermore, a calibration mechanism is provided on the outer side of the movable support and the base. The calibration mechanism includes a sliding foot fixedly connected to the bottom of the movable support and a positioning block movably connected to the outer wall of the base.

[0014] Furthermore, the positioning block is also provided with fixing bolts for fixing the positioning block to the outer wall of the base, and a scale is also provided within the range of motion of the positioning block on the outer wall of the base.

[0015] The beneficial effects of this utility model are as follows: 1. The wire cutting machine performs wire cutting by driving a continuously moving metal wire, which replaces the traditional cutting blade. This not only results in higher precision but also a smooth cut surface, and the workpiece is not deformed by external stress.

[0016] 2. Wire EDM machines do not require a drive to move the guide tip, nor do they need a CNC system or a guide tip drive. Compared to commonly used wire EDM machines, they are not only cheaper but also simpler to operate.

[0026] 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 specific embodiments.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, most metal products are currently cut using ordinary blade-type cutting machines, which are often not precise enough. Therefore, this invention designs a wire cutting machine 107 to drive the continuous movement of the metal wire 108. By driving the metal wire 108 to move continuously, the localized, instantaneous high temperature generated by the pulsed spark discharge between the metal wire 108 and the metal workpiece 01 is used to trim the edge of the metal workpiece 01, replacing the traditional cutting blade. This not only results in higher precision but also a smooth cut surface, and the workpiece is not deformed by external stress.

[0029] The wire EDM machine 107 is only used to drive the continuous movement of the metal wire 108 and the flow of working fluid, and does not drive the guide nozzle. Therefore, it is not equipped with a CNC system and a guide nozzle motion drive. Compared with commonly used wire EDM machines, it is not only cheaper but also simpler to operate.

[0030] Since each part is equipped with a CNC system and a guide nozzle motion drive, this utility model is modified to drive the metal workpiece 01 to move.

[0031] Specifically, a movable support 104 is provided in front of the wire EDM machine 107. The movable support 104 is movably connected to the base 101, while the base 101 is fixedly connected to the front side of the wire EDM machine 107. Additionally, a clamping assembly and a drive mechanism 102 are provided on the movable support 104. The clamping assembly is used to clamp and fix the metal workpiece 01, while the drive mechanism 102 is used to drive the metal workpiece 01 to rotate in coordination with the wire EDM machine 107 to complete the edge cutting.

[0032] The base 101 has slide rails on both sides, and the movable bracket 104 is slidably connected to the base 101 via the slide rails.

[0033] Preferably, the drive mechanism 102 is a servo motor.

[0034] The clamping assembly includes a positioning clamping plate 103 and a rotating clamping plate 106. The positioning clamping plate 103 and the rotating clamping plate 106 clamp and fix the metal workpiece 01 from below and above, respectively. The positioning clamping plate 103 is fixedly connected to the output shaft of the drive mechanism 102. A cylinder 105 is provided above the positioning clamping plate 103, and the rotating clamping plate 106 is rotatably connected to the output shaft of the cylinder 105.

[0035] Preferably, the drive mechanism 102 is fixedly installed at the bottom of the movable bracket 104, and the cylinder 105 is fixedly installed at the top of the movable bracket 104.

[0036] The metal workpiece 01 is clamped and fixed by setting a movable bracket 104 and a clamping component on the movable bracket 104. The metal workpiece 01 can be moved by moving the movable bracket 104. In addition, a drive mechanism 102 is set in the movable bracket 104 for rotating the clamping component, thereby driving the metal workpiece 01 to rotate in conjunction with the wire cutting machine 107 to complete the arc-shaped cutting edge. The structure is simple and the operation is convenient.

[0037] The first aspect of this utility model is as follows: Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in order to effectively cool and remove chips from the metal wire 108 and the metal workpiece 01 during cutting, several working fluid outlets 109 are provided below the wire guide nozzle on the wire cutting machine 107, and several working fluid return ports 110 are provided at the connection between the base 101 and the wire cutting machine 107, and the working fluid return ports 110 are located between the slide rails on both sides.

[0038] Since the working fluid outlet 109 is located close to the metal wire 108, the working fluid can flow down the metal wire 108 when it flows out of the working fluid outlet 109, achieving effective cooling and chip removal without the need for immersion.

[0039] The slide rails on both sides of the base 101 are not only used to move the movable bracket 104, but also to restrict the flow of working fluid, so that the working fluid can be returned through the working fluid return port 110, reducing waste.

[0040] In addition, a calibration mechanism is provided on the outer side of the movable support 104 and the base 101. The calibration mechanism includes a sliding foot 111 fixedly connected to the bottom of the movable support 104 and a positioning block 113 movably connected to the outer wall of the base 101. The positioning block 113 is also provided with a fixing bolt for fixing the positioning block 113 to the outer wall of the base 101, and a scale 112 is provided within the range of motion of the positioning block 113 on the outer wall of the base 101.

[0041] Therefore, when the movable support 104 is used to cut with the wire cutting machine 107, the accuracy can also be calibrated by the calibration mechanism. The positioning block 113 can be moved to the predetermined position and fixed in advance according to the scale 112. At this time, the positioning block 113 can block the sliding foot 111, thereby limiting the movement range of the movable support 104, achieving the calibration effect, and ensuring that the cutting edge accuracy meets the requirements.

[0042] In summary, this utility model's wire EDM machine 107 performs wire cutting by driving a continuously moving metal wire 108, replacing the traditional cutting blade. This not only results in higher precision and a smoother cut surface, but also prevents the workpiece from deforming due to external stress. The wire EDM machine 107 does not require driving the guide tip, nor does it need a CNC system or a guide tip drive motor. Compared to commonly used wire EDM machines, it is not only lower in cost but also simpler to operate.

[0043] The metal workpiece 01 is clamped and fixed by setting a movable bracket 104 and a clamping component on the movable bracket 104. The metal workpiece 01 can be moved by moving the movable bracket 104. In addition, a drive mechanism 102 is set in the movable bracket 104 for rotating the clamping component, thereby driving the metal workpiece 01 to rotate in conjunction with the wire cutting machine 107 to complete the arc-shaped cutting edge. The structure is simple and the operation is convenient.
