Description

Technical Field

[0001] The invention relates to the technical field of copper rod cold drawing, and in particular to a surface treatment device and process for a communication copper rod. Background Art

[0002] Copper is a tough, soft, ductile, purple-red and shiny metal. In the field of communications, copper rods are often used as conductors to transmit data. After the copper rods are made, the surface of the copper rods needs to be cold-drawn to improve the precision and surface finish of the copper rods.

[0003] Chinese patent CN113600726A discloses a stamping method for cold heading of hollow needle copper rods with rapid positioning and forming. The method includes selecting suitable copper metal materials and removing impurities on the surface of the copper metal materials, placing the materials on a punch press for preliminary processing to form copper metal strips, placing the copper metal strips on a lathe for processing to form copper metal columns, performing surface treatment on the copper metal columns, and placing the copper metal columns in a cold heading die of a cold heading machine for processing to form hollow needles.

[0004] But this technical solution has the following defects:

[0005] 1. This solution can only cold-draw one copper rod at a time. If multiple copper rods are cold-drawn at one time, the copper rods may not be firmly clamped due to the different thicknesses, resulting in low processing accuracy.

[0006] 2. This solution cannot ensure that the copper rod always enters the cold-drawn hole in a straight line during cold drawing. Since the copper rod is slender in shape, if it cannot enter the cold-drawn hole in a straight line, the copper rod may be broken;

[0007] 3. This solution cannot load multiple copper bars in an orderly manner, resulting in disordered loading. Summary of the invention

[0008] The purpose of the present invention is to address the deficiencies in the prior art and provide a surface treatment device for communication copper rods. The device adopts automatic feeding before cold drawing of the copper rods, and enables the copper rods after feeding to be in a horizontal state with equal spacing, thereby avoiding confusion in the copper rod feeding process, ensuring that the slender copper rods can always be fed in a straight line during the cold drawing process, and avoiding bending of the copper rods during the cold drawing feeding process.

[0073] Another object of the present invention is to provide a surface treatment device for a communication copper rod for use in a process for surface treatment of the copper rod in view of the deficiencies of the prior art, comprising the following steps:

[0074] Step 1: Loading process: the transfer roller takes out the copper bars in the guide rail in sequence through the transfer groove and slides them along the transition plate to between the first baffle plate and the second baffle plate;

[0075] Step 2: Alignment process: when the transfer slot drives a copper rod to enter between the first baffle plate and the second baffle plate, the first drive shaft drives the spur rack through the rack drive part to drive the lifting plate to move a fixed distance upward along the guide rail, and the lifting plate drives the card plate through the adjustment slot to block the corresponding falling copper rod;

[0076] Step 3: In the material pushing and clamping process, the first driving mechanism drives the telescopic rod through the push rod to move the copper rods arranged between the first baffle plate and the second baffle plate through the cold-drawn forming hole to the guide frame, and the cam assembly gradually clamps the copper rods of different thicknesses that are gradually pushed by the telescopic rod through the clamping plate;

[0077] Step 4: cold drawing process: the push-pull rod drives the bearing plate to move along the guide rod, the bearing plate drives the clamping plate to move through the guide frame, and the clamping plate drives the copper rod to move along the cold drawing forming hole to perform cold drawing forming work;

[0078] Step 5: Unloading process: take out the cold-drawn copper rods and place them in a storage rack for collection.

[0079] The beneficial effects of the present invention are:

[0080] (1) The present invention places a copper rod into a material guide rail and starts a driving motor located in a first mounting seat. The driving motor drives a driven roller to rotate through a first driving shaft under the action of a belt. The driven roller guides a copper rod out of the material guide rail at a time through a transfer roller under the action of a transfer groove. The guided copper rod slides along a transition plate to between the first material baffle plate and the second material baffle plate, so that the copper rod remains straight when it falls between the first material baffle plate and the second material baffle plate, ensuring that the left and right sides of the copper rod can always maintain the same straight line state during the feeding process of the copper rod into the cold-drawn forming hole.

[0081] (2) The present invention gradually reduces the spacing of the adjustment slots from bottom to top, so that during the gradual rise of the lifting plate, the card can be extended in sequence according to the order in which the transfer slots transfer the copper rods. After the second inclined portion is separated from the first inclined portion, the card transitions to the horizontal portion at the end, thereby achieving the goal of keeping the copper rods in a horizontal state with equal spacing after loading, thereby avoiding confusion during the copper rod loading process.

[0082] (3) The present invention drives the first cam member, the second cam member, the third cam member and the fourth cam member with different protrusion heights to rotate synchronously through the second driving shaft. The first cam member, the second cam member, the third cam member and the fourth cam member sequentially drive the clamping plate to move outward along the second guide groove, thereby achieving the effect of being able to synchronously clamp and cold-draw copper bars of different thicknesses at one time, with high cold-drawing efficiency, and selectively clamping copper bars of different thicknesses, so that the surface deformation of the copper bar under pressure during clamping is small.

[0083] (4) The present invention arranges an alignment process and a material pushing and clamping process in sequence before the cold drawing process, so that the slender copper rod before the feeding cold drawing process can be positioned left and right between the first material baffle plate and the second material baffle plate, and the lower part of the copper rod is positioned by the clamping plate, so that in the subsequent drawing component, the slender copper rod can be prevented from being fed deflected and broken during the cold drawing process of the copper rod, thereby ensuring that the feed can be fed in a straight line.

[0084] In summary, the present invention has the advantages of high cold drawing efficiency and the ability to ensure that copper rods are automatically sorted before feeding. BRIEF DESCRIPTION OF THE DRAWINGS

[0170] Support frame 301;

[0171] A guide rod 302, which is used to guide the material pulling assembly 22 and is connected to one end of the support frame 301;

[0172] A push-pull rod 303, used for driving the material pulling assembly 22, the push-pull rod 303 is connected to the side of the material pulling assembly 22;

[0173] One end of the push-pull rod 303 is provided with a driving cylinder;

[0174] The side of the support frame 301 is connected to a storage frame 304 for collecting the cold-drawn copper bars;

[0175] The cold-drawn plate 305 is connected to the side of the support frame 301 .

[0176] Furthermore, a cold-drawn forming hole 3052 is provided inside the cold-drawn plate 305;

[0177] Preferably, a cooling liquid pipe 3051 is provided on the upper portion of the cold drawing plate 305 for cooling the copper rod to be cold drawn;

[0178] The cold-drawn forming holes 3052 are provided in a plurality of groups and are located on the same vertical line as the sorting component 12 .

[0179] It should be added that one end of the slender copper rod needs to be preliminarily pressed and thinned before cold drawing, so that the copper rod can be inserted into the cold drawing forming hole 3052 at the beginning of cold drawing;

[0180] It should be added that the present invention is explained by taking the cold drawing of four copper bars at one time as an example, wherein the upper end surface of the clamping plate 124 from bottom to top between the first baffle plate 121 and the second baffle plate 122 is at the same horizontal height as the cold drawing forming hole 3052 in the corresponding cold drawing plate 305.

[0181] It should be noted that when using Figure 2-3 As shown, a copper rod is placed in the guide rail 1101, and a driving motor located in the first mounting seat 1263 is started. The driving motor drives the driven roller 1111 to rotate through the first driving shaft 126 under the action of the belt 1112. The driven roller 1111 guides a copper rod out of the guide rail 1101 at a time through the transfer roller 111 under the action of the transfer groove 1110. The guided copper rod slides along the transition plate 112 to between the first baffle plate 121 and the second baffle plate 122, so that the copper rod remains straight when falling between the first baffle plate 121 and the second baffle plate 122, ensuring that the left and right sides of the copper rod can always maintain the same straight line state during the feeding process of the copper rod into the cold-drawn forming hole 3052.

[0182] like Figure 4-5 As shown, initially, the second inclined portion 1241 is above the first inclined portion 12321. While the first driving shaft 126 drives the belt 1112 to rotate, the first driving shaft 126 drives the spur rack 125 to move upward through the rack driving portion 1261. The spur rack 125 drives the lifting plate 123 to move upward and gradually compress the first return spring 1231. The lifting plate 123 acts tangentially between the first inclined portion 12321 and the second inclined portion 1241, so that the second inclined portion 1241 drives the clamping plate 124 to compress the second return spring 1243 and extend to The copper rods that are about to fall are blocked between the second baffle plate 122 and the first baffle plate 121. The present invention gradually reduces the spacing of the adjustment slots 1232 from bottom to top, so that during the gradual rise of the lifting plate 123, the clamping plate 124 can be extended in sequence according to the order in which the transfer slots 1110 transfer the copper rods. After the second inclined portion 1241 is separated from the first inclined portion 12321, the clamping plate 124 transitions to the horizontal portion 12322 at the end, thereby achieving the goal of keeping the copper rods in a horizontal state with equal spacing after loading, avoiding the phenomenon of confusion during the copper rod loading process.

[0183] After every four copper rods are loaded, Figure 4-5 As shown, at this time, the first drive shaft 126 switches from the original rack drive part 1261 meshing with the spur rack 125 to a state where the curved surface part 1262 and the spur rack 125 are in a gap state, so that the lifting plate 123 is pushed downward to reset under the action of the first reset spring 1231;

[0184] After the copper rod feeding work is completed, Figure 3 , Figure 6-7 , Figure 10-13 As shown, the first driving mechanism 211 is started, and the first driving mechanism 211 drives the telescopic rod 213 to move through the push rod 212, and the telescopic rod 213 synchronously drives the copper rod to pass through the cold-drawn forming hole 3052 and then enter between the two sets of guide frames 222, and the servo driving motor at one end of the second driving shaft 2250 is started. The servo motor drives the first cam member 2251, the second cam member 2252, the third cam member 2253 and the fourth cam member 2254 of different protrusion heights to rotate synchronously through the second driving shaft 2250, and the first cam member 2251, the second cam member 2252, the third cam member 2253, and the fourth cam member 2254 sequentially drive the clamping plate 223 to move outward along the second guide groove 2221, wherein, as shown in FIG. Fig.12 As shown, the thickest copper rod a is clamped by the clamping plate 223 that extends out first and has the smallest extension distance, and then the telescopic rod 213 corresponding to the push of copper rod a moves along the first guide groove 2121 and compresses the adjustment spring 214 to compensate for the distance moved by the push rod 212 in the copper rod a, and the remaining three copper rods b, c, and d with smaller diameters than copper rod a pass through the clamping plate 223 pushed by the first cam member 2251 and enter the clamping plate 223 pushed by the second cam member 2252, so that the second thickest copper rod b is clamped, and the clamping is carried out in sequence in this way until the thinnest copper rod d is clamped by the clamping plate 223 lifted by the fourth cam member 2254 with the highest protrusion height, thereby achieving the effect of being able to synchronously clamp and cold-draw copper rods of different thicknesses at one time, with high cold-drawing efficiency, and selectively clamping copper rods of different thicknesses, so that the surface of the copper rod is compressed and deformed less during clamping;

[0185] After the copper rod is clamped, the cylinder at one end of the push-pull rod 303 is started. The cylinder drives the supporting plate 221 to move along the guide rod 302 through the push-pull rod 303. The supporting plate 221 cold-draws the clamped copper rod along the cold-drawing forming hole 3052 through the guide frame 222. The copper rod that has been cold-drawn is taken out and placed on the upper part of the storage rack 304 for storage and the next set of cold-drawing work is carried out.

[0189] Step 2: Alignment process: when the transfer slot 1110 drives a copper rod to enter between the first baffle plate 121 and the second baffle plate 122, the first drive shaft 126 drives the spur rack 125 through the rack drive unit 1261 to drive the lifting plate 123 to move upward along the guide rail 1221 for a fixed distance, and the lifting plate 123 drives the clamping plate 124 through the adjustment slot 1232 to block the corresponding falling copper rod;

[0190] Step 3: In the material pushing and clamping process, the first driving mechanism 211 drives the telescopic rod 213 through the push rod 212 to move the copper bars arranged between the first baffle plate 121 and the second baffle plate 122 through the cold-drawn forming holes 3052 to the guide frame 222, and the cam assembly 225 gradually clamps the copper bars of different thicknesses that are gradually pushed by the telescopic rod 213 through the clamping plate 223;

[0191] Step 4, cold drawing process, the push-pull rod 303 drives the bearing plate 221 to move along the guide rod 302, the bearing plate 221 drives the clamping plate 223 to move through the guide frame 222, and the clamping plate 223 drives the copper rod to move along the cold drawing forming hole 3052 to perform cold drawing forming work;

[0192] Step 5: unloading process, taking out the cold-drawn copper rods and placing them in the storage rack 304 for collection.

[0193] It should be noted that the present invention can position the slender copper rod before the feeding cold drawing process left and right between the first baffle plate 121 and the second baffle plate 122 by sequentially arranging the aligning process and the pushing and clamping process before the cold drawing process, and position the lower part of the copper rod by the clamping plate 124, so that in the subsequent drawing component 22, the slender copper rod can be prevented from being fed deflected and caused to break during the cold drawing process of the copper rod, ensuring that the feed can be fed in a straight line.
