[0034] The following is combined with Figure 1 -Attached Figure 5 The present invention is described in further detail.

[0035] The embodiment of the invention discloses a copper wire drawing machine with a cooling device.

The machine body 1 is provided with a sedimentation tank 103 located below the wire drawing die 2, and the sedimentation tank 103 is used to collect cooling lubricating liquid with copper chips. Drawing copper wire by a copper wire drawing machine is a technical content well known to those skilled in the art, and the wire inlet die 101, the wire drawing die 2 and the wire outlet die 102 are not described in detail here.

[0037] Reference Figure 1 and Figure 2 The machine body 1 is provided with a connecting frame 3 that slides along the long side direction of the machine body 1, and the machine body 1 is provided with a driving component 4 for driving the connecting frame 3 to reciprocate. The connecting frame 3 is slidably connected with an upper mold 5 and a lower mold 6, and both the upper mold 5 and the lower mold 6 reciprocate in the vertical direction. The connecting frame 3 is provided with a control component 7 for driving the upper mold 5 and the lower mold 6 to move closer to each other or away from each other.

[0038] Reference Figure 3 and Figure 4 The bottom surface of the upper mold 5 and the top surface of the lower mold 6 are both provided with cooling grooves 8, and the cooling grooves 8 are semi-cylindrical as a whole. The two cooling grooves 8 cooperate to form a cooling cavity 9, and the cooling cavity 9 is cylindrical as a whole. The copper wire enters from one end of the cooling cavity 9 and passes through the middle of the cooling cavity 9, then passes out from the other end of the cooling cavity 9 and then enters into the wire drawing die 2. The end of the cooling cavity 9 close to the wire drawing die 2 is set to be truncated cone-shaped and the small diameter surface faces the wire drawing die 2. A feeding channel 10 for cooling and lubricating liquid to enter the cooling cavity 9 is provided in the upper mold 5. A feed groove 11 is provided on the side of the upper mold 5 and the lower mold 6 close to the wire drawing die 2. The two feed grooves 11 cooperate to form an annular feed cavity 12. The side wall of the feed cavity 12 matches the side wall of the die hole of the wire drawing die 2, and a feed channel 13 connected to the feed cavity 12 is provided in the lower mold 6.

[0039] The cooling chamber 9 is filled with cooling lubricant, which cools and lubricates the copper wire before it enters the wire drawing die 2. Compared with the common method of spraying cooling lubricant, the cooling chamber 9 can make the cooling lubricant evenly adhere to the surface of the copper wire, thus avoiding the cooling lubricant on the copper wire from being scraped off as much as possible, reducing the occurrence of uneven cooling and lubrication, and thus improving the wire drawing effect of the device and the quality of the finished copper wire.

[0040] The end of the cooling chamber 9 is set to be truncated into a cone shape facing the wire drawing die 2, so that the liquid in the cooling chamber 9 is sprayed toward the side wall of the die hole of the wire drawing die 2, which can achieve the purpose of cleaning the copper chips accumulated on the side wall of the die hole of the wire drawing die 2 with the cooling lubricating liquid, reduce the influence of the accumulated copper chips on the copper wire drawing, and further improve the copper wire drawing effect and the quality of the finished product; a feeding chamber 12 is set, so that the cooling lubricating liquid can be quickly discharged along the feeding chamber 12 after entering the die hole, thereby reducing the residence and accumulation of copper chips in the die hole, reducing the situation where copper chips enter the die hole together with the copper wire, and reducing the probability of copper wire breakage.

[0041] Reference Figure 3 and Figure 5 A flushing nozzle 14 is connected to the upper die 5 , and the nozzle of the flushing nozzle 14 is directed toward the copper wire after being drawn by the drawing die 2 . The flushing nozzle 14 is connected to the feed channel 10 .

[0042] The flushing nozzle 14 cleans the copper wire after drawing to facilitate the subsequent storage of the copper wire.

[0043] Reference Figure 3 and Figure 5 The flushing nozzle 14 is rotatably connected to the upper mold 5 through a hose, and a rotating component 15 is provided on the upper mold 5 for rotating the flushing nozzle 14 to rotate the nozzle toward the copper wire at the die hole of the wire drawing die 2.

[0044] Directing the flushing nozzle 14 toward the die hole can clean the die hole and reduce the accumulation of copper chips. Setting the flushing nozzle 14 to rotate can reduce conflicts between devices and improve the flexibility of the device. The rotated flushing nozzle 14 can be closer to the die hole, further improving the cleaning effect.

[0045] Reference Figure 1 and Figure 2 The driving assembly 4 is provided with two groups and is respectively connected to both sides of the connecting frame 3. The driving assembly 4 includes a driving motor 41, a driving gear 42 and a driving rack 43. The driving rack 43 is fixedly connected to the body 1. The driving gear 42 is fixedly connected to the output end of the driving motor 41 and meshes with the driving rack 43.

[0046] The driving motor 41 is started to drive the driving gear 42 to rotate, thereby moving the connecting frame 3 along the long side direction of the machine body 1, so as to facilitate the control of the position of the connecting frame 3 and facilitate use.

[0047] Reference Figure 1 and Figure 2 The control assembly 7 is provided with two groups and is respectively provided on both sides of the connection frame 3. The control assembly 7 includes a control motor and a control screw 71. The control motor is provided in the connection frame 3. The control screw 71 is vertically rotatably provided in the connection frame 3 and is fixedly connected to the output end of the control motor. The control screw 71 passes through the lower mold 6 and the upper mold 5 in sequence in a threaded connection manner. The upper and lower parts of the control screw 71 are provided with threads with opposite rotation directions. The rotation of the control screw 71 by the control motor belongs to the technical content well known to those skilled in the art, so the control motor is not shown in the figure.

[0048] The control motor rotates, driving the control screw 71 to rotate, so that the upper mold 5 and the lower mold 6 can be moved closer to each other or away from each other. The structure is stable and easy to control.

[0049] The thread pitch of the upper portion of the control screw 71 is greater than the thread pitch of the lower portion of the control screw 71 .

[0050] The displacement distance of the upper mold 5 can be made larger, which is beneficial to expanding the interval between devices and facilitating the inspection and maintenance of the devices, etc., and there is no need to expand the displacement distance of the lower mold 6 downward, so as to facilitate the discharge of cooling lubricating fluid containing copper chips into the sedimentation tank 103 on the body 1.

[0051] Reference Figure 5The rotating assembly 15 includes a first hydraulic cylinder 151, a second hydraulic cylinder 152, a moving rack 153 and a rotating gear 154. The first hydraulic cylinder 151 and the second hydraulic cylinder 152 are connected through an oil pipe. The first hydraulic cylinder 151 is connected to the upper die 5 and its output end can abut against the side wall of the wire drawing die 2. The second hydraulic cylinder 152 is connected to the upper die 5. The moving rack 153 is fixedly connected to the output end of the second hydraulic cylinder 152. The rotating gear 154 is fixedly connected to the rotating shaft of the flushing nozzle 14, and the rotating gear 154 is meshed with the moving rack 153. In order to ensure the clarity of the illustration, not all flushing nozzles 14 and all rotating assemblies 15 are fully shown in the figure.

[0052] Reference Figure 2 , Figure 3 and Figure 5 , the connecting frame 3 is close to the drawing die 2, the output end of the first hydraulic cylinder 151 is in contact with the drawing die 2, and the output end of the first hydraulic cylinder 151 is retracted into the first hydraulic cylinder 151 under the pushing action of the drawing die 2, and the oil in the first hydraulic cylinder 151 enters the second hydraulic cylinder 152 through the oil pipe, so that the output end of the second hydraulic cylinder 152 drives the moving rack 153 to move, and drives the rotating gear 154 to rotate, so as to realize the rotation of the flushing nozzle 14, and rotate the flushing nozzle 14 to an inclined setting, so as to facilitate the control of the rotation timing of the flushing nozzle 14 and avoid conflicts between devices as much as possible.

[0053] Reference Figure 5 The rotating assembly 15 further includes a return spring 155 sleeved on the output end of the first hydraulic cylinder 151 , and the return spring 155 makes the output end of the first hydraulic cylinder 151 have a movement tendency to extend out of the first hydraulic cylinder 151 .

[0054] Reference Figure 2 , Figure 3 and Figure 5 When the connecting frame 3 is away from the wire drawing die 2, the reset spring 155 pushes the output end of the first hydraulic cylinder 151, so that the output end of the first hydraulic cylinder 151 extends out of the first hydraulic cylinder 151. As the output end of the first hydraulic cylinder 151 moves, the oil in the second hydraulic cylinder 152 enters the first hydraulic cylinder 151 through the oil pipe, and the output end of the second hydraulic cylinder 152 retracts into the second hydraulic cylinder 152, which drives the moving rack 153 to move again, and then the rotating gear 154 rotates, so that the flushing nozzle 14 rotates to a horizontal state to prevent the flushing nozzle 14 from conflicting with other structures, facilitate the reset of the device, and improve the degree of automation of the device.

[0055] The implementation principle of a copper wire drawing machine with a cooling device according to an embodiment of the present invention is as follows:

[0056] Start the drive motor 41 and the control motor to make the connecting frame 3, the upper mold 5 and the lower mold 6 approach the drawing mold 2, and the upper mold 5 and the lower mold 6 move in the vertical direction and approach each other until the upper mold 5 abuts against the drawing mold 2 and the upper mold 5 and the lower mold 6 abut against each other.

[0057] During the abutment between the upper mold 5 and the drawing mold 2, the output end of the first hydraulic cylinder 151 retracts, the output end of the second hydraulic cylinder 152 extends, the movable rack 153 moves, driving the rotating gear 154 to rotate, so that the flushing nozzle 14 connected to the upper mold 5 rotates to an inclined state, and the nozzle of the flushing nozzle 14 faces the mold hole of the drawing mold 2.

[0058] The cooling groove 8 on the bottom surface of the upper mold 5 cooperates with the cooling groove 8 on the top surface of the lower mold 6 to form a cooling cavity 9. The copper wire passes through the middle of the cooling cavity 9 and penetrates into the wire drawing die 2. The truncated cone-shaped opening of the cooling cavity 9 faces the die hole of the wire drawing die 2.

[0059] Part of the cooling lubricant enters the cooling chamber 9 through the feed pipe to lubricate and cool the copper wire, and then is sprayed into the die hole to wash away the copper chips on the side wall of the die hole and the copper wire. After that, the cooling lubricant containing the copper chips flows downward along the discharge chamber 12 and the discharge channel 13 to the sedimentation tank 103.

[0060] Part of the cooling lubricant is used to flush the copper wire and the die hole of the drawing die 2 after drawing through the hose and the flushing nozzle 14.

[0061] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
