Description

Technical Field

[0001] The present application relates to the field of grinding and polishing equipment, and in particular to an armor wire cold end polishing machine. Background Art

[0002] Armor wire electric heating is an environmentally friendly, energy-saving and economical heating method. Armor wire electric heating is widely used in national defense research, aerospace, electrical machinery, chemical machinery, rubber machinery, printing machinery, plastic machinery, packaging machinery, and household appliances. Electric heating as a clean energy is widely used in various fields of our life and industry.

[0003] refer to Figure 1 The armored heating wire 1 (referred to as armor wire) generally includes a heating coil 12 as a heating part and a cold end 11 connected to a power source. The cold end 11 includes a low-resistance power line 13 and a stainless steel metal shell that wraps the power line 13. The metal shell of the cold end 11 is filled with glass powder to separate the metal shell from the power line 13. During the processing, infrared rays or other heating methods are required to melt the glass powder. The outer side of the metal shell of the cold end 11 will turn black due to heating, affecting the appearance of the product. In this regard, after the overall assembly of the armor wire is completed, the surface of the cold end 11 of the armor wire needs to be polished.

[0004] The cold end of the armor wire is designed with different lengths and diameters according to the application and heating power. At present, in many manufacturers, the cold end of the armor wire is usually polished manually. One person holds the cold end of the stainless steel armor wire, and the other person holds dozens of turns of the stainless steel armor wire heating coil. One person rotates the cold end of the armor wire for polishing, and the other person drags dozens of turns of the stainless steel armor wire heating coil to follow. When polishing the cold end of the stainless steel armor wire, two people are required to polish and polish it, which is a waste of labor; because the cold end of the armor wire and the heating coil rotate synchronously, two people need to cooperate with each other to polish the cold end of the armor wire. Sometimes, because the two workers do not cooperate well, the rotation of the cold end of the armor wire and the heating coil is not synchronized, which interferes with the processing state of the cold end of the armor wire (sudden offset, vibration, etc.), resulting in poor quality of polishing the cold end of the stainless steel armor wire, and rework or scrapping.

[0005] In response to the above-mentioned related technologies, the applicant conducted a survey on the grinding equipment on the market and did not find any grinding equipment specifically used for or suitable for grinding and polishing the cold end of the armor wire. Considering that manual grinding and polishing of the cold end of the stainless steel armor wire is inefficient and has uneven quality, in order to optimize the shortcomings of pure manual operation, the applicant has developed a polishing machine for grinding the cold end of the armor wire to optimize the polishing process of the cold end of the armor wire. Summary of the invention

[0006] In order to optimize the grinding and polishing process of the cold end of the armor wire, the present application provides an armor wire cold end polishing machine, which has the effect of improving the processing efficiency of the cold end of the armor wire and ensuring the processing quality of the cold end of the armor wire.

[0007] The present application provides an armor wire cold end polishing machine adopts the following technical solution:

[0008] A cold end polishing machine for an armor wire comprises a grinding station and a polishing station, wherein the grinding station comprises a cold end support assembly and a grinding assembly; the cold end support assembly comprises a first bracket for mounting the cold end of the armor wire, a cold end limit frame for limiting the position of the cold end of the armor wire, and a first linear drive member for driving the first bracket and the cold end limit frame to approach the grinding assembly; a circular arc groove for abutting the cold end of the armor wire is provided on one side of the cold end limit frame close to the grinding assembly; after the cold end of the armor wire is mounted on the first bracket, the cold end of the armor wire is located in the circular arc groove.

[0009] By adopting the above technical solution, when in use, the pipeline structure (heating coil and power cord) at both ends of the cold end of the armor wire is set on the first bracket, and then the cold end of the armor wire is set; the equipment is started, the grinding assembly starts to run, and the first linear drive member drives the first bracket and the cold end limit frame to approach the grinding belt, and then drives the cold end of the armor wire to press on the grinding part of the grinding assembly to grind the side wall of the cold end of the armor wire; the worker holds the heating coil part of the armor wire, drives the cold end of the armor wire to rotate by rotating the heating coil, and completes the grinding of the entire periphery of the cold end of the armor wire. By using an armor wire cold end polishing machine provided by the present application, one worker can operate the equipment to complete the grinding of the cold end of the armor wire, saving manpower and improving efficiency; and because it is changed to single-person operation, it can reliably ensure that the cold end of the armor wire and the heating ring rotate synchronously, avoiding processing quality problems caused by insufficient tacit understanding between workers, which can effectively improve processing efficiency and ensure processing quality; because the cold end of the armor wire is fixed during the grinding process by the first bracket and the cold end limit bracket, there is no need for workers to hold the cold end for grinding, which avoids the processing safety hazards of hand-held grinding and effectively avoids hand injuries caused by careless operation of workers. Since the cold end of the armor wire is located in the arc groove, the arc groove will limit the axial position of the cold end of the armor wire. During the grinding process, the cold end of the armor wire can rotate around its own axis without easily deviating from the axis. The grinding thickness and quality can be better controlled to avoid excessive local grinding or uneven grinding quality due to manual operation errors. The distance between the cold end limit frame and the grinding assembly is also set in advance and controlled by the first linear drive component. In this way, there is no need to rely excessively on the worker's experience to control the grinding distance, which can reduce the requirements for worker experience, reduce labor costs, and improve processing efficiency.

[0010] Optionally, the central angle of the circular arc groove is greater than 180 degrees; a waste chip hole is provided on the cold end limit frame, the axis of the waste chip hole is parallel to the axis of the circular arc groove, and the waste chip hole intersects with the hole contour of the circular arc groove;

[0011] It further includes a limiting member, the limiting member includes a fixing post inserted and cooperated with the waste chip hole and a limiting portion located in the arc groove, and the limiting portion is fixed on the fixing post; sealing plates are installed on both sides of the cold-end limiting frame, the sealing plates block both ends of the waste chip hole, and avoidance grooves are formed in the sealing plates corresponding to the arc groove;

[0012] Chip discharge holes are formed through the lower groove wall of the arc groove, and a plurality of chip discharge holes are arranged along the axial direction of the arc groove.

[0013] By adopting the above technical solutions, the arc groove is greater than 180 degrees. When grinding the cold end of the armor wire, the cold end of the armor wire penetrates into the arc groove. The arc groove can more completely limit the axial position of the cold end of the armor wire, and the position state of the cold end of the armor wire during processing is more stable, which can better guarantee the processing quality of the cold end of the armor wire. To ensure the limiting effect of the arc groove on the cold end of the armor wire, the sizes of the arc groove and the cold end of the armor wire need to be close. The waste chip hole is provided to collect the metal waste chips adhered to the cold end of the armor wire, preventing the accumulation of waste chips between the cold end of the armor wire and the groove wall of the arc groove from affecting the grinding quality. The fixing part of the limiting member is partially inserted into the arc groove for fixation, and the limiting portion corresponds to the communication seam structure between the arc groove and the waste chip hole; both ends of the opening of the arc groove facing the grinding assembly cooperate with the limiting portion to form a three-line limiting structure, which can limit the cylindrical cold end of the armor wire. In this way, by inserting the limiting member, the cold end of the armor wire with a smaller size can be limited, and then the grinding process can be carried out stably; taking the limiting portion as the abutting limiting structure, when processing the cold end of the armor wire, a large gap is left between the cold end of the armor wire and the inner wall of the arc groove, which can be used as a chip discharge groove. In actual production, there are various sizes of the cold end of the armor wire. If cold-end limiting frames with arc grooves of different sizes are set corresponding to the cold ends of the armor wires of various sizes, it is necessary to frequently replace the cold-end limiting frames, which is extremely inconvenient and costly; by fixing the limiting member in the original waste chip hole, not only can a new chip discharge groove structure be formed to retain the chip discharge function, but also the cold ends of the armor wires of different sizes can be limited, and corresponding limiting members with different sizes can be set, and the manufacturing cost can be effectively reduced. The sealing plate structure can fix the limiting member, prevent the limiting member from moving axially, and prevent interfering with the processing of the cold end of the armor wire. The chip discharge hole structure is added to further ensure the smooth discharge of the grinding waste chips.

[0014] Optionally, the grinding assembly includes a first driving component, a driving pulley driven by the first driving component, a driven pulley engaged with the driving pulley, and a grinding belt wound between the driving pulley and the driven pulley; the first linear driving member includes a driving cylinder, a pressure control valve for controlling the pressure of the driving cylinder, a pushing slide table for mounting the first bracket and the cold-end limiting bracket, and a guiding slide rail engaged with the pushing slide table, and the end of the movable shaft of the driving cylinder is fixedly connected to the pushing slide table; a limiting bracket is further provided on one side of the first bracket close to the grinding assembly, and the limiting bracket is located on the movement track of the first bracket and abuts and limits the movement range of the first bracket.

[0015] By adopting the above technical solution, by selecting a driving cylinder to push the first bracket and the cold-end limiting bracket to move, the pressure control valve can be used to control the pressing force of the cold-end limiting bracket in the cold-end support assembly, and the relevant parameters of the cold end of the grinding wire can be adjusted more conveniently; the cooperation of the guiding slider and the guiding slide rail can ensure the stable movement of the cold-end support assembly fixed on the guiding slider, and can ensure that the cold end is stably pressed on the grinding belt. The grinding belt is used for grinding, and the grinding belt itself has a certain elasticity, which can prevent the cold end of the wire from being in too tight contact with the grinding surface to a certain extent, and is convenient for ensuring the grinding quality. A limiting bracket is provided to limit the moving distance of the first bracket. Since the first bracket and the cold-end limiting bracket move together with the pushing slide table, abutting and limiting the moving distance helps to stably control the distance between the cold-end limiting bracket and the grinding belt, and further facilitates the control of the grinding thickness of the cold end of the wire, which helps to improve the grinding quality. Compared with manual operation, the stability is better, and the requirements for the experience of workers are lower.

[0016] Optionally, the grinding assembly further includes a tensioning pulley and a guiding pulley; the tensioning pulley is arranged in parallel with the driving pulley, the tensioning pulley is arranged on the side of the grinding belt away from the cold-end limiting bracket, and the tensioning pulley is located between the cold-end limiting bracket and the driven pulley; the guiding pulley is arranged between the tensioning pulley and the driven pulley, and the guiding pulley includes two groups of guiding wheels arranged on both sides of the grinding belt and a guiding bracket for mounting the guiding wheels, the guiding wheels are rotatably mounted on the guiding bracket, and the rotating shaft of the guiding wheel is perpendicular to the grinding surface of the grinding belt.

[0017] By adopting the above technical solution, the tension pulley can tighten the grinding belt, ensuring the tension of the grinding belt, which helps to stably control the distance and pressing force between the grinding belt and the cold end, and guarantees the grinding quality. The guide pulley arranged between the tension pulley and the driven pulley can straighten the grinding belt, preventing the dislocation of the position of the grinding belt. In actual processing, the lengths of the cold ends are different, and the width of the grinding belt cannot grind the entire cold end. Workers need to drag the cold end to move it horizontally for comprehensive grinding. Setting the guide pulley to limit the position of the grinding belt can prevent the position deviation of the grinding belt along with the horizontal movement of the cold end, ensuring the grinding quality.

[0018] Optionally, a translation slide rail parallel to the axis of the driving pulley is arranged on the pushing slide table, and a translation slide table sliding along the translation slide rail is installed on the translation slide rail; the first bracket and the cold end limiting bracket are fixed on the translation slide rail.

[0019] By adopting the above technical solution, by setting the translation slide rail and the translation slide table, workers can more conveniently move the first bracket and the cold end limiting bracket as a whole and then move the cold end of the armor wire, which is convenient for comprehensively grinding and processing the cold end of the armor wire with a longer length by moving the cold end of the armor wire; at the same time, since the lengths of some cold ends of the armor wire are different, by moving the frame body, the cold end of the armor wire can also be adjusted to be directly opposite to the grinding belt, facilitating the grinding of the cold end of the armor wire.

[0020] Optionally, the first bracket includes a rear support arm and a front support arm arranged on both sides of the cold end limiting bracket. A support hole for passing the power line is penetrated through the rear support arm, and a U-shaped groove for passing the heating coil is penetrated through the front support arm corresponding to the support hole. The support hole, the U-shaped groove and the arc groove are all located on the same axis. A movable pull pin for preventing the pipeline structure of the armor wire from coming out is movably arranged on one side of the U-shaped groove.

[0021] By adopting the above technical solution, the cold end of the armor wire is inserted into the arc groove, and the power line at one end of the cold end of the armor wire is inserted into the support hole. After the cold end is completely inserted, the heating coil part of the cold end of the armor wire is inserted into the U-shaped groove, and the movable pull pin is lowered to prevent the heating coil from coming out; in this way, the cold end of the armor wire is installed on the first bracket and the cold end limiting bracket.

[0022] Optionally, it further includes a master control switch and a foot switch. The master control switch controls the power supply of the whole machine, and the foot switch controls the movement of the first linear driving member.

[0023] By adopting the above technical solution, when the master control switch is started, the grinding assembly starts to operate; after the armor wire is installed on the first bracket and the cold end limiting bracket, the worker holds the heating coil part with both hands, steps on the foot switch, starts the first linear driving member, and sends the cold end of the armor wire to the position of the grinding assembly for grinding; the pneumatic operation of the first linear driving member does not require manual operation by the worker and can be achieved by stepping on the foot, which facilitates single-person operation.

[0024] Optionally, the polishing station includes a polishing support assembly and a polishing assembly; the polishing support assembly includes a second bracket for mounting the cold end of the armored wire and a second linear drive for driving the second bracket close to the polishing assembly; the polishing assembly includes a second drive component and a polishing wheel.

[0025] By adopting the above technical solution, the cold end of the armored wire after grinding is polished to ensure the surface quality of the product and optimize the customer experience.

[0026] Optionally, it further includes a chip removal assembly, which includes a suction fan and a suction pipe installed on the suction fan, and there are two suction pipes corresponding to the grinding station and the polishing station.

[0027] By adopting the above technical solution, the processing waste chips are timely extracted to prevent affecting the processing and ensure the processing quality.

[0028] Optionally, it further includes a transparent protective cover. There are two transparent protective covers that respectively cover the grinding station and the polishing station. The suction pipe penetrates into the transparent protective cover, and an installation opening for installing the cold end of the armored wire is provided on one side of the transparent protective cover.

[0029] By adopting the above technical solution, the transparent protective cover is set to separate the processing station from the external environment, block the flying iron chips, and better prevent pollution and ensure the safety of processing personnel.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting a cold end support assembly and a grinding assembly at the grinding station, the cold end support assembly supports the cold end, replacing manual holding, realizing single-person operation to improve processing efficiency and quality, and at the same time being able to reduce the safety hazards of manual holding processing. The cold end support assembly includes a first linear drive, a first bracket, and a cold end limit frame. The first bracket fixes both ends of the cold end of the armored wire, and the cold end limit frame fixes the cold end of the armored wire, which can effectively ensure the stability during the grinding process of the cold end of the armored wire. The first linear drive can realize the automatic movement of the cold end of the armored wire, move the cold end of the armored wire to the position of the grinding assembly for grinding, better liberate the hands of workers, and facilitate single-person processing;

[0065] Refer to Figure 11 and

[0066] Refer to Figure 12 The cold end of the armor wire is pushed out through two limiters, and the cold end 11 of the armor wire with a small size can also be limited and ground by the cold end limiting frame 42, improving the usability of the device.

[0067] Refer to Figure 13 and Figure 14, the polishing station 6 includes a polishing sheet metal bracket 96 as a frame body, and a polishing support assembly 61 and a polishing assembly 62 mounted on the polishing sheet metal bracket 96. The polishing support assembly 61 includes a second bracket 611 for mounting the cold end 11 of the armor wire and a second linear drive member 612 for driving the second bracket 611 to approach the polishing assembly 62; the second linear drive member 612 has the same structure as the first linear drive member 43, and the second bracket 611 has the same structure as the first bracket 41. The polishing assembly 62 includes a second drive component 621 and a polishing wheel 622. The second drive component 621 is a drive motor, and the polishing wheel 622 is a felt wheel.

[0068] The usage process of the embodiment of the present application is as follows: for the grinding operation, first pull up the movable draw pin 413, and the cold end 11 of the armor wire passes through the U-shaped groove 4121 of the front support arm 412 of the first bracket 41, passes through the arc groove 421 of the cold end limiting frame 42 and the support hole 4111 of the rear support arm 411, and then mounts the cold end 11 of the armor wire. Put down the movable draw pin 413, and the rear heating coil 12 part is wound into a disk shape and held by the worker. Start the power-on switch 911 corresponding to the grinding station 3, and the first drive component 51 starts to operate. The worker triggers the foot switch 92 corresponding to the grinding station 3 with the foot. The first linear drive member 43 drives the first bracket 41 and the cold end limiting frame 42 to approach the grinding belt 54. The cold end limiting frame 42 presses the cold end 11 of the armor wire against the grinding belt 54 for grinding. During this process, the worker holds the heating coil 12 and rotates it to drive the cold end 11 of the armor wire to rotate; the worker holds the heating coil 12 part of the armor wire and drives the cold end 11 of the armor wire to rotate by rotating the heating coil 12 to complete the grinding of the entire outer circumference of the cold end 11 of the armor wire; after reaching the set time, the driving cylinder 431 automatically retracts. After grinding, it can be directly switched to the polishing station 6 for polishing, or the ground cold end 11 of the armor wire can be removed and placed aside. Without turning off the power, directly replace the armor wire, and then trigger the foot switch 92 again. After that, the ground armor wire is centrally transferred to the polishing station 6 for polishing.

[0069] The implementation principle of the embodiment of this application is as follows: The fixation of the cold end 11 of the armor wire during the grinding process is completed through the first bracket 41 and the cold end limiting bracket 42, avoiding the processing safety hazards of manual grinding by workers and effectively preventing hand injuries caused by careless operation of workers. Since the cold end 11 of the armor wire is located in the arc groove 421, the arc groove 421 will limit the axial position of the cold end 11 of the armor wire. During the grinding process, the cold end 11 of the armor wire can rotate around its own axis and is not prone to axial deviation. The grinding thickness and quality can be better controlled, avoiding excessive local grinding or uneven grinding quality caused by manual operation errors. At the same time, the cold end limiting bracket 42 moves synchronously with the first bracket 41, and the movement range of the first bracket 41 is restricted by the limiting bracket 97. The relative position between the cold end 11 of the armor wire and the grinding belt 54 during the processing state can be stably controlled. By adjusting the air pressure through the pressure control valve, the pressure during the grinding process can also be stably controlled. This can reduce the experience requirements for workers, reduce labor costs and difficulties, and improve processing efficiency.

[0070] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
