Description

Technical Field

[0001] The invention belongs to the technical field of wire cutting, and in particular relates to a stripping, straightening and cutting mechanism. Background Art

[0002] After the existing aluminum wire, copper wire and other wires are drawn, there are oil stains and defects on the surface of the wires. The acid cleaning method commonly used in the prior art is to remove the oil stains. However, with the demand for environmental protection, acid cleaning is difficult to meet the needs of the market and enterprises. There are also peeling tools to peel a layer of the wire surface to achieve the purpose of cleaning.

[0003] However, due to structural defects, the existing peeling tools, such as the patent application number 201310231928.6, discloses a fully automatic straight wire processing production line, including a wire pay-off machine, a wheel straightener, a compression scraping unit, a traction reel, a wire feeding straightening system, and a flying shear numbering machine arranged in sequence in the horizontal direction. The advantage of the present invention is that it can realize the continuous processing of scraping, straightening, cutting, and numbering of metal straight wire. The wire feeding straightening system adopts two sets of wire feeding mechanisms, and a pressure wheel straightening mechanism is arranged in the middle, so that the straightened metal straight wire always maintains a straight state. The wire feeding mechanism adopts the pneumatic opening and closing form of the upper and lower synchronous crawlers through the power cylinder arranged on the lower slide plate. The wire pressing part adopts two rows of synchronous pressure wheels to press against the synchronous crawlers, which increases the contact area with the wire and is more conducive to maintaining the linear characteristics of the wire. The synchronous crawler clamps the wire feeding, reduces the scratches on the surface of the wire, effectively guarantees the quality of the wire surface, and saves the subsequent cleaning and polishing processes of the wire. During use, the wire stripping process is prone to partial stripping or unclean stripping. At the same time, the stripping machine and the cutting machine are two separate machines. The wire is directly fed from the stripping machine into the cutting machine. It is difficult to match the speed between the stripping machine and the cutting machine, resulting in wire damage or wire breakage. The structure is unreasonable and the reliability of use is low. In addition, the existing equipment transmission mechanism adopts an open gear mechanism, the gears wear quickly and have a short service life, the belts wear quickly, and the degree of automation of the equipment electrical control is low, which brings troubles to people. Therefore, it is necessary to study a stripping, straightening and cutting mechanism. Summary of the invention

DETAILED DESCRIPTION

[0036] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0037] Example 1: This example provides a peeling, straightening and cutting mechanism, which is mainly used for the production and cutting of non-ferrous metal straight wires, especially aluminum alloy welding wires. The welding wires have high requirements on the surface, and existing equipment is difficult to meet people's requirements. For this reason, this example provides a peeling, straightening and cutting mechanism to ensure that no impurities are generated in the welding wire during the welding process, thereby ensuring the welding quality.

[0038] like Figure 1-2 As shown, a stripping, straightening and cutting mechanism includes a pay-off unit 1, a stripping mechanism, a tension adjustment mechanism, a cutting and numbering mechanism and a collection box 10; after the wire 11 is paid off, it enters the stripping machine to undergo a stripping surface treatment, and then the wire is cut into fixed-length products through a straightening and cutting process, and a numbering mark is performed on a section of the product; the basic process is through pay-off - stripping - tension adjustment - cutting and numbering - wire collection, to achieve the functions of fixed-length cutting and numbering of the wire, focusing on the process of stripping first and then cutting, and a tension adjustment mechanism is provided between the stripping machine and the cutting machine, so that the equipment can work stably and reliably.

[0039] In this embodiment, Figure 3-4 As shown, the stripping mechanism includes a wire-input stabilizing device 2, a stripping tool holder 3, a traction unit 4 and a chip collecting box; the wire-input stabilizing device 2 includes a horizontal wire-stabilizing roller group 21 and a vertical wire-stabilizing roller group 22, and a wire drawing die 31 and a stripping die 32 are arranged in the stripping tool holder 3. After the wire is drawn out from the wire-releasing unit 1, it passes through the horizontal wire-stabilizing roller group 21, the vertical wire-stabilizing roller group 22, the wire drawing die 31, the stripping die 32 and the traction unit 4 in sequence, as shown in FIG. Figure 1As shown, the stripping die is located between the front and rear wire drawing dies and is provided with one or more, and each stripping die is installed in the center hole of the fixed seat through a joint bearing, the wire drawing die at the front end is directly fixed in the fixed seat, and the wire drawing die at the rear end is directly fixed or installed in the fixed seat through a joint bearing. The wire is stripped under the traction of the traction unit 4, and the surface of the wire is peeled off. The peeling thickness is about 0.03-0.05mm (depending on the thickness and surface quality of the wire. When there are more surface defects, the peeling amount can be increased), and the peeled wire skin falls into the chip collection box at the bottom of the stripping tool; the stripping tool is also provided with a cooling (water circulation system) and a lubrication system (drawing oil system), which are respectively used to cool and lubricate the stripping tool.

[0040] In this embodiment, the wire is first adjusted horizontally and vertically before entering the peeling tool. There are two functions here. One is to stabilize the wire to prevent the shaking of the wire on the wire-laying unit 1 from causing the shaking of the wire in subsequent work. The second is to have a rough straightening effect to ensure that the wire enters the peeling tool smoothly. Figure 1 The horizontal stabilizing roller group 21 and the vertical stabilizing roller group 22 shown both include a plurality of upper pressing rollers and lower pressing rollers, and the wire material passes between the upper pressing rollers and the lower pressing rollers.

[0041] The traction unit includes a motor, a roller and a wire-dividing wheel. The motor is connected to the roller in a transmission manner. The wire-dividing wheel is arranged directly below the roller and functions to separate the wires on the roller laterally during traction work so as to protect the wires from mutual friction, thereby preventing scratches on the surface and avoiding mutual friction damage between the wires.

[0042] like Figure 5-9 As shown, the tension adjustment mechanism 5 is arranged between the peeling mechanism and the cutting and marking mechanism, and is used to adjust the tension and speed of the wire between the peeling mechanism and the cutting and marking mechanism. The tension adjustment mechanism in this embodiment includes an upper fixed wheel 52, a lower movable wheel 53, an adjusting seat plate 55, a displacement sensor 57 and an adjusting cylinder 54. The wire is wound around the upper fixed wheel 52 and the lower movable wheel 53, and the axle of the lower movable wheel 53 is inserted into the flat hole and fixed on the adjusting seat plate 55. Positioning slide rods 56 and adjusting cylinders 54 are respectively arranged on both sides and the middle of the adjusting seat plate 55, so that the lower movable wheel can be driven up and down by the adjusting cylinder. The displacement sensor 57 is arranged on the side of the adjusting seat plate 55 to adjust the tension of the wire. At the same time, a wire length detection sensor 51 is arranged at the wire inlet of the tension adjustment mechanism 5. The wire length detection sensor 51 is used to measure the conveying speed of the wire and upload it to the PLC controller.

[0043] During specific use, when the speeds of the front and rear devices are inconsistent, that is, there is a speed difference, the downstream wheel will produce a corresponding lifting displacement, and the detection block 59 will produce corresponding changes according to the lifting displacement. The displacement sensor can obtain a corresponding electrical signal (voltage or current) according to the displacement change of the detection block. The control system uploads this signal to the PLC controller, and then the PLC controller adjusts the speed of the traction unit of the front peeling mechanism and the clamping drive motor of the rear cutting and numbering unit to make the conveying speeds of the two tend to be consistent.

[0044] like Figure 10-11 As shown, the cutting and numbering mechanism includes a front belt pushing unit 6, a straightening unit 7, a rear belt pushing unit 8 and a cutting and numbering unit 9. The wire 11 passes through the front belt pushing unit 6, the straightening unit 7 and the belt pushing unit 8 in sequence and then enters the cutting and numbering unit 9; the straightening unit 7 includes horizontal straightening and vertical straightening to straighten the wire. The straightener adopts a digital scale adjustment method to effectively improve the straightening accuracy and reliability of the wire. It is mainly used to straighten the wire to ensure the straightness of the wire. At the same time, a wire length detection sensor is arranged at the front end of the rear belt pushing unit 8 to detect the actual speed of the wire before cutting and numbering, and upload it to the PLC controller to provide accurate speed information for the cutting and numbering unit.

[0045] The cutting and marking machine unit 9 includes a front positioning fixture 94, two cutter discs 91, a cutting knife 92, a numbering block 93 and a rear positioning fixture 95. The two cutter discs 91 are symmetrically arranged along the vertical direction, and corresponding cutting knives 92 and numbering blocks 93 are arranged at the symmetrical points of the two cutter discs; the front positioning fixture 94 and the rear positioning fixture 95 are respectively arranged on the front and rear sides of the two cutting rollers, so that the wire is always in the middle of the two cutter discs in the horizontal direction; the wire enters between the two cutter discs through the positioning hole, and as the two cutter discs rotate, the cutting knives and numbering blocks on the two cutter discs cyclically engage to achieve the cutting and marking of the wire, and the cut wire falls into the collection box through the conveying roller. The cutting is driven by a servo motor, and the wire is cut by a wheel-type flying shear driven by a reducer, and the wheel-type cutting realizes the numbering processing at the same time. The upper and lower cutter discs are respectively equipped with a cutting knife and a numbering block, and the cutting knife realizes the cutting function, and the two numbering blocks realize the numbering of the wire diameter and material specifications, and the cutting length of the wire can be controlled by controlling the speed of the servo motor.

[0046] At the same time, the present invention adopts PLC program control, variable frequency speed regulation, touch screen + button control mode, the cutting length and cutting quantity can be manually input, and the cutting parameters (including wire diameter, length, speed, etc.) can be input on the touch screen to realize continuous automatic production.

[0047] Therefore, this embodiment combines the stripping mechanism and the cutting and numbering mechanism together through the tension adjustment mechanism. After the wire-paying part pays out the wire, the wire is pulled by the traction part of the stripping machine. After the stripping process, it passes through the tension adjustment mechanism (the tension adjustment mechanism is used to match the speed and tension of the belt pushing device of the stripping machine and the cutting machine) and enters the cutting machine. The belt pushing device of the cutting machine pushes the wire into the cutting and numbering part. The cutting and numbering part drives the servo motor according to the fixed length signal and speed signal given by the PLC signal input previously, and cuts the wire for numbering.

[0048] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that this embodiment further limits the structure of the tension adjustment mechanism.

[0049] like Fig.17 As shown, the tension adjustment mechanism is arranged between the peeling mechanism and the cutting and marking mechanism, and is used to adjust the tension and speed of the wire between the peeling mechanism and the cutting and marking mechanism. The tension adjustment mechanism includes an adjusting wheel 53, a detection block 59 and a detection module. The adjusting wheel 53 is connected to the driving structure in a transmission manner, and the tension of the wire is adjusted under the drive of the driving structure. The detection block 59 is connected to the adjusting wheel in a corresponding manner and responds to the displacement of the adjusting wheel. The detection module is arranged in a corresponding manner to the detection block and detects the displacement of the block; a driving rocker is arranged on the back of the adjusting wheel, and the driving structure is pneumatic. The cylinder body and rod body of the cylinder are respectively hinged on the driving swing arm and the fixed seat, so that the cylinder can drive the adjusting wheel to rotate. An adjusting rod is fixed on the front of the adjusting wheel, and a guide wheel is arranged at the end of the adjusting rod. The adjusting rod rotates with the adjusting wheel to change the point where the guide wheel supports the wire, so as to adjust the tension of the wire. The detection module is a displacement sensor 57. The detection block is arranged on the back of the adjusting wheel 53, and its outer side is an arc surface. The points of the outer arc surface have a gradually increasing or decreasing distance relative to the displacement sensor as the adjusting wheel rotates. The displacement sensor faces the detection block and detects the displacement.

[0050] Or Fig.18 As shown, the tension adjustment structure includes an adjusting wheel 53, and a detection block 59 is integrally connected to the back of the adjusting wheel 53. The bottom of the detection block 59 is arc-shaped, and a displacement sensor 57 is correspondingly arranged on it. A driving rod is arranged on the front of the adjusting wheel. The driving rod can be driven by the adjusting cylinder and drives the adjusting wheel at the root to rotate and the guide wheel 58 at the end to swing. The guide wheel adjusts the tension of the wire during the swinging process.

[0051] In this embodiment, another tension adjustment mechanism is provided, which adjusts the tension by changing the support point of the guide wheel. It is easy to operate, has stable cylinder drive, is easy to install and maintain. The detection module can also use a rotary encoder. The rotary encoder collects the rotation angle of the adjusting wheel 53 by meshing with the adjusting wheel 53, and then determines the rotation amplitude of the adjusting wheel according to the rotation angle, and converts the swing amplitude of the guide wheel 58.

[0052] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that: this embodiment further limits the structure of the peeling tool.

[0053] like Figure 3-4 As shown, a flexible clamping unit is provided at the front end of the stripping knife holder, and the flexible clamping unit includes two bottom rollers and an adjusting roller, and the adjusting roller is located on the upper part of the two bottom rollers, thereby forming an isosceles triangle-shaped flexible clamping unit, wherein the bottom roller plays a supporting role, and the adjusting roller presses on the top of the wire. The flexible clamping unit is a device to prevent the wire from shaking during the stripping process. Once the wire shakes during the stripping process, the surface of the wire will not be shiny and scars will appear on the surface of the wire.

[0054] The wire drawing die and the stripping die are both installed at the wire entry end of the fixed seat; the stripping die is covered with a joint bearing, and the stripping die is installed in the center hole of the fixed seat through the joint bearing. In this embodiment, the wire drawing die is installed on the fixed seats at both ends of the equipment base plate, and the stripping die is installed on the fixed seats in the middle of the equipment base plate, and the wire drawing die 31 and the stripping die 32 are both installed at the wire entry end of the corresponding fixed seat. The wire drawing die 31 and the stripping die 32 are respectively covered with a fixed sleeve, and the fixed sleeve outside the wire drawing die is directly installed in the center hole of the fixed seat, and the fixed sleeve of the stripping die is covered with a joint bearing, and the stripping die is installed in the center hole of the fixed seat through the joint bearing. A mold pressure cover is also provided at the outer end of the fixed sleeve, and the mold pressure cover is respectively located at the outer ends of the stripping die and the wire drawing die, and the stripping die and the wire drawing die are limited and fixed to prevent them from loosening.

[0055] The two wire drawing dies draw the wire into a reference line, which helps the stripping die in the middle to strip the straight wire surface smoothly. Among them, the joint bearing outside the stripping die will automatically adapt to the wire path to reduce the degree of wire stripping and automatically rotate to adjust the angle, which is conducive to aligning the center line of the stripping die with the center line of the wire. When the wire stripping is eccentric or the stripping is not clean, the stripping die can be adjusted through the joint bearing to make the stripping die slightly change its angle to correct the eccentricity and thus strip cleanly.

[0056] Embodiment 4: This embodiment is basically the same as Embodiment 1, except that: this embodiment further describes the structures of the front belt push unit and the rear belt push unit.

[0057] like Figure 12-16 As shown, the front belt pushing unit and the rear belt pushing unit are symmetrically arranged on the front and rear sides of the correction unit, and the rear belt pushing unit includes an upper pushing unit, a lower pushing unit and a driving motor; the upper pushing unit and the lower pushing unit are symmetrically arranged in the horizontal direction, and the driving wheels of the two pushing units are connected by gear transmission; the driving wheel of the front pushing unit is connected to the driving wheel of the rear pushing unit by a synchronous belt transmission, so that the front pushing unit and the rear pushing unit are synchronously driven by a driving motor.

[0058] The upper pushing unit includes a driving wheel 81, a driven wheel 82, a support roller group 85 and a tensioning roller 84; a driving wheel 86 is arranged on the axle of the driving wheel 81, and the driving wheel 86 is connected to the driving motor through a belt transmission, and the driven wheel and the driving wheel are connected through a belt transmission. The support roller group and the tensioning roller are respectively located on the upper and lower sides, and the structure of the lower pushing unit is basically the same as that of the upper pushing unit. The belts of the upper pushing unit and the lower pushing unit are arranged face to face. When working, the two belts clamp the wire material forward. In addition, the middle part of the lower belt pushing device, the upper support roller group and the lower tensioning roller part are an integrated structure. This mechanism can be driven up and down by a cylinder. After descending, a gap for threading appears between the upper and lower belts, which is convenient for threading operation.

[0059] In this embodiment, the front belt pushing unit and the rear belt pushing unit are synchronously driven by the same drive motor, and the two can ensure the same speed, avoiding the problems of front and rear asynchronism and slipping. Each group of belt pushing devices uses two upper and lower synchronous belts for clamping, and the wire has a large force area, is not easy to slip, and the surface is not easy to be damaged.

[0060] In addition, the existing gears are placed outside the environment, and the gears are greatly worn out after long-term use. For this reason, the driving wheel of the lower pushing unit and the driving wheel of the upper pushing unit in this embodiment are arranged in a sealed box, that is, the gears are placed in the sealed box body, and there is lubricating oil underneath. When the gears rotate, the two gears can be oiled at the same time, and dust and stains can be prevented from falling between the gears, thereby extending the working life of the gears. In this way, a stable and long-lasting working life of the equipment can be guaranteed.
