Description

Technical Field

[0001] The invention relates to the technical field of alloy resistor production, in particular to a copper material double-row slotting device for alloy resistors. Background Art

[0002] The two pins of the alloy resistor are mainly made of copper material. In the production process of the alloy resistor, it is usually necessary to perform double-row slotting on the rolled copper material 10 (such as Figure 1 When double-row grooving the copper material 10, the industry typically places multiple die cutters in the direction of the copper material's travel. Each die cutter has a different angle with the copper material, and the contact depth between the die cutter and the copper material also varies.

[0003] like Figure 2 As shown, for example, three die cutters are sequentially arranged in the direction of travel of the copper material 10. The angle between the first die cutter 11 and the copper material 10 is 30 degrees, the angle between the second die cutter 12 and the copper material 10 is 27 degrees, and the angle between the third die cutter 13 and the copper material 10 is 24 degrees. The second die cutter 12 is 0.1 mm deeper than the first die cutter 11, and the third die cutter 13 is further 0.1 mm deeper than the second die cutter 12. In this way, continuous grooving can be achieved in the direction of travel of the copper material 10.

[0004] However, the above-mentioned mold knives all perform grooving in a "shoveling" manner against the moving direction of the copper material. During the long-term contact between the mold knives and the copper material, the mold knives are very likely to wear and break.

[0005] In addition, during the process of grooving the copper material 10, a layer of oil film needs to be coated on the surface of the copper material 10 for lubrication and heat dissipation. After each die cutter removes the waste material on the surface of the copper material 10, the oil film will be taken away accordingly. Therefore, the copper material 10 needs to be oiled twice, which will waste a lot of oil. Summary of the Invention

[0021] like Figure 3 As shown, the present invention discloses a double-row slotting device 20 for copper material used in alloy resistors, which continuously slots a copper material 10. The double-row slotting device 20 for copper material used in alloy resistors includes a feed roller mechanism 30, a slotting mechanism 40, a discharge roller mechanism 50, and a winding mechanism 60, which are sequentially arranged along the linear direction of the copper material 10.

[0022] In the present invention, the number of the slotting mechanisms 40 is two (eg Figure 6 As shown in FIG, two slotting mechanisms 40 are arranged at intervals along a direction perpendicular to the linear travel of the copper material 10, thereby performing double-row slotting on the copper material 10. Of course, in other embodiments, multiple slotting mechanisms 40 may be provided according to actual conditions, thereby performing multiple slotting on the copper material 10.

[0023] Next, the specific structure of the above-mentioned feed roller mechanism 30 is described: like Figure 3 As shown, the feed roller mechanism 30 includes a feed roller seat 31, a lower feed roller 32, an upper feed roller 33, and a feed roller drive unit 34. The lower feed roller 32 is fixed to the feed roller seat 31, and the upper feed roller 33 is movably mounted on the feed roller seat 31. The feed roller drive unit 34 is used to drive the upper feed roller 33 toward or away from the lower feed roller 32. In this embodiment, the feed roller drive unit 34 is a cylinder drive structure.

[0024] Next, the specific structure of the slotting mechanism 40 is described: like Figure 4 As shown, the slotting mechanism 40 includes an oiling portion 100 , a cutting portion 200 , and a scraper 300 , which are sequentially arranged along the linear travel direction of the copper material 10 .

[0025] like Figure 4As shown, the oiling unit 100 is used to apply oil to the surface of the copper material 10. Specifically, the oiling unit 100 includes: an oil storage tank 110 and an oiling structure 120. The oil storage tank 110 and the oiling structure 120 are connected by an oil delivery pipe 130. The oil storage tank 110 supplies oil to the oiling structure 120 through the oil delivery pipe 130, and the oiling structure 120 is used to apply the supplied oil to the surface of the copper material 10. Please refer to Figure 4 and Figure 5 Furthermore, the oiling structure 120 includes a base 121 and a floating head 122. The base 121 defines an oiling cavity 123, and the floating head 122 is movably received in the oiling cavity 123 by a spring 124. The sidewall of the floating head 122 defines an oiling groove 125. The wall of the oiling cavity 123 forms a narrowing ring 126. One end of the floating head 122 has a tapered surface 127 that presses against the narrowing ring 126.

[0026] like Figure 6 As shown, the cutting section 200 includes a plurality of fine cutting knives 210, which are arranged in sequence and spaced apart along a direction perpendicular to the straight line of the copper material 10, with a gap formed between two adjacent fine cutting knives 210; Figure 7 As shown, the fine cutting knife 210 has a cutting blade 211, which gradually approaches the copper material 10 along the straight moving direction of the copper material 10. The two ends of the cutting blade 211 form a separation end 212 and a contact end 213. The separation end 212 is non-contact with the copper material 10, and the contact end 213 is inserted into the copper material 10. like Figure 7 As shown, the scraper 300 has a wedge-shaped scraping blade 310 , which forms a scraping contact surface 311 and a scraping inclined surface 312 . The scraping contact surface 311 is in contact with the surface of the copper material 10 , and the scraping inclined surface 312 is inclined at an angle to the surface of the copper material 10 .

[0027] Next, the specific structure of the above-mentioned discharge roller mechanism 50 is described: like Figure 3 As shown, the discharge roller mechanism 50 includes a discharge roller seat 51, a lower discharge roller 52, an upper discharge roller 53, and a discharge roller drive unit 54. The lower discharge roller 52 is fixed to the discharge roller seat 51, and the upper discharge roller 53 is movably mounted on the discharge roller seat 51. The discharge roller drive unit 54 is used to drive the upper discharge roller 53 toward or away from the lower discharge roller 52. In this embodiment, the discharge roller drive unit 54 is a cylinder drive structure.

[0028] Next, the specific structure of the winding mechanism 60 is described: like Figure 3 As shown, the winding mechanism 60 includes a winding disk 61 and a winding driving portion 62 drivingly connected to the winding disk 61 .

[0029] Next, the working principle of the above-mentioned copper material double-row slotting device 20 for alloy resistors is described: The copper material 10 passes through the feed roller mechanism 30, the slotting mechanism 40, the discharge roller mechanism 50, and the winding mechanism 60 in sequence. The slotting mechanism 40 continuously slots the copper material 10. The feed roller mechanism 30 and the discharge roller mechanism 50 are respectively provided on both sides of the slotting mechanism 40. The feed roller mechanism 30 and the discharge roller mechanism 50 tighten the copper material 10, so that the slotting mechanism 40 can stably and continuously slot the copper material 10. like Figure 3 As shown, the feed roller driving unit 34 drives the upper feed roller 33 toward the lower feed roller 32, so that the copper material 10 can be clamped by the upper feed roller 33 and the lower feed roller 32. Similarly, the discharge roller driving unit 54 drives the upper discharge roller 53 toward the lower discharge roller 52, so that the copper material 10 can be clamped by the upper discharge roller 53 and the lower discharge roller 52. As a result, the copper material 10 can be in a taut state, which is convenient for the slotting mechanism 40 to slot it stably. like Figure 5 As shown, when the copper material 10 passes through the oiling portion 100, due to the certain thickness of the copper material 10, the floating head 122 is lifted by the copper material 10, and the conical surface 127 of the floating head 122 is no longer pressed on the narrowing ring 126. A gap is formed between the conical surface 127 and the narrowing ring 126. Under the action of pressure, the oil in the oil storage tank 110 sequentially passes through the oil groove 125 on the side wall of the floating head 122, the gap between the conical surface 127 and the narrowing ring 126, and finally flows out to the surface of the copper material 10. It can be understood that after the grooving of the copper material 10 is completed, the copper material 10 completely leaves the floating head 122. The floating head 122 is reset under the elastic restoring force of the spring 124, and the conical surface 127 is pressed against the narrowing ring 126 again, thereby blocking the gap and preventing the oil from flowing out. After the copper material 10 is oiled, an oil film is formed on its surface. The oil film has good lubrication and heat dissipation effects, making it easier for the cutter part 200 and the scraper 300 to groove it. When the copper material 10 reaches the cutting part 200, a plurality of fine cutting knives 210 are arranged in sequence and spaced apart in a direction perpendicular to the straight line of the copper material 10, and a gap is formed between two adjacent fine cutting knives 210. In this way, the copper material 10 will be partially cut, thereby forming a "fin slot" 101 structure (such as Figure 6 As shown); it can be understood that if a plurality of fine cutting knives 210 are not provided and arranged in sequence, but the cutting knives are formed into a whole without intervals, cutting cannot be achieved; like Figure 7As shown, the two ends of the cutting blade 211 form a separation end 212 and a contact end 213. The separation end 212 is non-contacting with the copper material 10, and the contact end 213 is inserted into the copper material 10. It can be understood that the cutting blade 211 partially removes the copper material 10 in a "scraping" manner. The advantage of this "scraping" manner is that the cutting blade 211 can be adjusted to a specified depth to remove the copper material 10 at one time, and the problem of blade breakage is not likely to occur. There is no need to set up multiple mold knives for processing as described in the background art. like Figure 7 As shown, the copper material 10 reaches the scraper 300, and the scraping contact surface 311 is tightly attached to the surface of the copper material 10, and the scraping inclined surface 312 scrapes away the waste remaining in the above-mentioned "fin groove" 101. It can be understood that scraping is necessary to remove the waste remaining in the "fin groove" completely; During the process of the scraping blade 310 scraping the copper material 10, the remaining waste forms a "fin groove" structure, and a gap is formed between adjacent waste materials. The oil film on the surface of the copper material 10 can also better enter this gap, and the resistance encountered by the scraping blade 310 is also greatly reduced. The scraping blade 310 can be directly set to the specified depth and remove the remaining waste materials at one time. Here, it should be noted that, as described in the background technology, a technical solution of using multiple mold knives to scrape from shallow to deep, after each mold knife scrapes the surface of the copper material once, the oil film on its surface will be taken away by the waste material, and it will need to be oiled a second time, which will waste a lot of oil; the present invention is different. The copper material is cut off by the cutting part 200 to obtain a "fin groove", so that part of the oil will flow into the "fin groove" without the need for secondary oiling, and the scraping blade 310 will then scrape the remaining waste material at one time.

[0030] The present invention is a double-row grooving device for copper materials of alloy resistors, which particularly optimizes the structure of the grooving mechanism 40 to solve the problem of knife breakage easily caused by the traditional arrangement of multiple mold knives for grooving in a "shoveling" manner, and also solves the problem of oil waste caused by the traditional arrangement of multiple mold knives for grooving in a "shoveling" manner.

[0031] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
