Description

Technical Field

[0001] This invention relates to the field of copper rod drawing technology, and more particularly to a drawing device for high-purity oxygen-free copper rods. Background Technology

[0002] A drawing machine is an industrial piece of equipment composed of mechanical equipment, lubrication equipment, electrical equipment, hydraulic and pneumatic systems, etc. It is used to draw metal materials. The drawing machine is used to draw metals at room temperature. Copper rod is a non-ferrous metal rod. Copper is made of copper, has high electrical conductivity, and is widely used. In the production process of oxygen-free copper rod, a drawing machine is needed to further process the copper rod so that the copper rod can be longer and the diameter of the copper rod can be changed to meet the required diameter.

[0003] Currently, existing equipment for drawing copper rods is mainly divided into chain drawing machines, hydraulic drawing machines, and drum drawing machines. Because the equipment needs to go back and forth to draw the copper rod, these machines occupy a relatively large area. However, in actual use, when the copper rod is long, one round trip is not enough to completely draw the copper rod. The equipment needs to return and clamp the copper rod again for another drawing. During this process, the copper rod will be intermittently paused. When it is suddenly subjected to force again, it is easy for the copper rod to break. Therefore, there is an urgent need to design a high-purity oxygen-free copper rod drawing equipment to solve the above problems. Summary of the Invention

The first and second moving plates are slidably sleeved on the outer circumference of the first and second horizontal bars, respectively. A mating plate is fixedly connected to the bottom outer wall of the first moving plate and the top outer wall of the second moving plate.

[0007] As a preferred embodiment of the present invention, a first cylinder and a second cylinder are fixedly connected to the bottom outer wall of the first side plate and the top outer wall of the second side plate, respectively. One end of the top piston rod of the first cylinder is fixedly connected to the bottom outer wall of the first lifting block, and one end of the bottom piston rod of the second cylinder is fixedly connected to the top outer wall of the second lifting block. A pneumatic rod is fixedly connected to one side outer wall of both the first and second vertical plates. An inner rod that is sealed and inserted between the inner circumference of the pneumatic rod is fixedly connected to one side outer wall of both the first and second moving plates. An air supply pipe is fixedly connected between the pneumatic rod and both the first and second cylinders.

[0008] As a preferred embodiment of the present invention, multiple anti-slip plates are fixedly connected to the inner walls of opposite sides of the docking plate at equal intervals.

[0009] As a preferred embodiment of the present invention, the reciprocating mechanism includes a first reciprocating lead screw and a second reciprocating lead screw, and a fixing plate is fixedly connected to one end of the outer wall of the second main board. A first gear plate and a second gear plate are rotatably connected to the top and bottom of one end of the outer wall of the fixing plate, respectively. The first reciprocating lead screw and the second reciprocating lead screw are fixedly connected to one end of the outer wall of the first gear plate and the second gear plate, respectively. A toothed belt is meshed between the circumferential outer walls of the first gear plate and the second gear plate. A first drive motor is fixedly connected to the other end of the outer wall of the second main board, and one end of the output shaft of the first drive motor is fixedly connected to the other end of the outer wall of the first gear plate.

[0010] As a preferred embodiment of the present invention, the first moving block and the second moving block are respectively sleeved on the outer wall of one end of the first reciprocating screw and the outer wall of the other end of the second reciprocating screw.

[0011] As a preferred embodiment of the present invention, a plurality of first position sensors are provided on one side of the outer wall of the second motherboard, and a plurality of second position sensors are provided on one side of the outer wall of the other end of the third motherboard. Both the first position sensors and the second position sensors are electrically connected to the second drive motor.

[0012] As a preferred embodiment of the present invention, through holes are opened between the outer walls of both ends of the first motherboard, the second motherboard and the third motherboard, and a molded cylinder is fixedly connected to both sides of the outer wall of the other end of the second motherboard.

Two second hydraulic cylinders are fixedly connected to the middle position of one end of the outer wall of the push plate. A clamping plate is fixedly connected to one end of the piston rod of each of the second hydraulic cylinders. A mating hole corresponding to the through hole is opened between the two ends of the outer wall of the push plate.

[0015] In summary, the beneficial effects of this solution are as follows:

[0016] Firstly, when oxygen-free copper rods need to be drawn, the feeding mechanism can automatically feed the copper rods. When the copper rod passes through the second main board, the fixing mechanism will repeatedly reciprocate under the action of the reciprocating mechanism, and alternately fix and clamp the copper rods, thereby achieving uninterrupted fixing and clamping of the copper rods and the drawing effect. It requires less floor space and prevents the copper rods from breaking under intermittent drawing.

[0017] Secondly, when the first drive motor starts, it can drive the first gear plate to rotate. At this time, under the action of the toothed belt, the second gear plate will also rotate at the same time. Therefore, the first reciprocating screw and the second reciprocating screw will also rotate at the same time. Since the first moving block and the second moving block are threadedly connected to the first reciprocating screw and the second reciprocating screw respectively, and the first moving block and the second moving block are respectively set at one end of the first reciprocating screw and the other end of the second reciprocating screw, the first moving block and the second moving block will move back and forth in opposite directions at the same time, and drive the fixed copper rod to move back and forth for pulling.

[0018] Thirdly: When the worker feeds the copper column into the forming cylinder through the through hole, the second hydraulic cylinder is activated. The second hydraulic cylinder will drive the clamping plate to move and use the clamping plate and baffle to fix the copper column. At this time, the first hydraulic cylinder is activated, and the fixed copper column is directly squeezed into the forming cylinder, and the copper column extends out of the second main plate, realizing the automatic feeding effect of the copper column.

A plurality of second connecting rods 7, evenly distributed, are fixedly connected to the outer wall of one end of the second main plate 6. A third main plate 8 is fixedly connected between the outer walls of the second connecting rods 7 at one end. A feeding mechanism for extruding the copper rods is provided on the outer wall of one end of the first main plate 1. The top and bottom outer walls of the outer wall of one end of the second main plate 6 are provided with feeding mechanisms for... The fixing mechanism for clamping the copper rod has a reciprocating mechanism on the outer wall of one end of the second main board 6 for driving the fixing mechanism. When it is necessary to pull the oxygen-free copper rod, the copper rod can be automatically fed by the feeding mechanism. When the copper rod passes through the second main board 6, the fixing mechanism will repeatedly reciprocate under the action of the reciprocating mechanism and clamp the copper rod in turn, thereby realizing the continuous clamping and pulling effect of the copper rod. It requires less floor space and prevents the copper rod from breaking under intermittent pulling.

[0030] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7The fixing mechanism includes two limiting rods 15, and the outer circumferential walls of the limiting rods 15 are respectively slidably fitted with a first moving block 28 and a second moving block 35. The outer walls of both sides of the first moving block 28 are fixedly connected to a first side plate 27, and the outer walls of both sides of the second moving block 35 are fixedly connected to a second side plate. One side wall of both the first side plate 27 and the second side plate has a lifting groove. The inner walls of the lifting grooves are respectively slidably connected to a first lifting block 26 and a second lifting block. One side wall of the first lifting block 26 and the second lifting block are respectively fixedly connected to a first bracket 25 and a second bracket. The bottom outer wall of the first bracket 25 and the top outer wall of the second bracket are respectively fixedly connected to a lifting plate 24. The outer walls of both sides of the lifting plate 24 are respectively fixedly connected to a first vertical plate 23 and a second vertical plate. The inner walls of the opposite sides of the first vertical plate 23 and the second vertical plate are respectively rotatably connected to a first horizontal bar 33, a first bidirectional threaded rod 31, a second horizontal bar, and a second bidirectional threaded rod. The two first vertical plates 23 and the first... A second drive motor 22 is fixedly connected to one side of the outer wall of each of the two vertical plates. One end of the output shaft of the second drive motor 22 is fixedly connected to one side of the outer wall of the first bidirectional threaded rod 31 and the second bidirectional threaded rod, respectively. The outer circumference of the first bidirectional threaded rod 31 and the second bidirectional threaded rod is respectively threadedly sleeved with a first moving plate 34 and a second moving plate. The first moving plate 34 and the second moving plate are respectively slidably sleeved on the outer circumference of the first crossbar 33 and the second crossbar. The bottom outer wall of the first moving plate 34 and the top outer wall of the second moving plate are fixedly connected with a docking plate 30. When the second drive motor 22 starts and drives the first bidirectional threaded rod 31 and the second bidirectional threaded rod to rotate, the first moving plate 34 and the second moving plate will move in the same direction or in opposite directions under the action of the first bidirectional threaded rod 31 and the second bidirectional threaded rod. When the first moving plate 34 or the second moving plate moves towards each other, it will drive the docking plate 30 to fix and clamp the copper column passing through the second main plate 6.

[0031] Reference Figure 5 , Figure 6 and Figure 7A first cylinder 20 and a second cylinder are fixedly connected to the bottom outer wall of the first side plate 27 and the top outer wall of the second side plate, respectively. One end of the top piston rod of the first cylinder 20 is fixedly connected to the bottom outer wall of the first lifting block 26, and one end of the bottom piston rod of the second cylinder is fixedly connected to the top outer wall of the second lifting block. A pneumatic rod 21 is fixedly connected to one side outer wall of the first vertical plate 23 and the second vertical plate. An inner rod 32, which is sealed and inserted between the inner circumference of the pneumatic rod 21, is fixedly connected to one side outer wall of the first moving plate 34 and the second moving plate. An air supply pipe is fixedly connected between the pneumatic rod 21 and the first cylinder 20 and the second cylinder. When the first moving plate 34 approaches each other and is about to fix the copper column... During the clamping process, the inner rod 32 is gradually pulled out from the air rod 21, reducing the pressure in the air rod 21. This leads to a decrease in the pressure inside the first cylinder 20. At this time, the first lifting block 26 will drive the first bracket 25 to descend, thereby clamping the copper column. Conversely, the first lifting block 26 will drive the first bracket 25 to rise. When the second moving plates approach each other, the inner rod 32 will also gradually be pulled out from the air rod 21, causing a decrease in the pressure inside the second cylinder. Under the action of pressure, the second lifting block will be lifted upward by the second cylinder, allowing the other docking plates 30 to clamp the copper column. Conversely, the second lifting block will descend, ensuring that the several docking plates 30 do not affect each other when moving laterally.

[0032] Reference Figure 6 Multiple anti-slip plates 29 are fixedly connected to the inner walls of opposite sides of the docking plate 30.

[0033] Reference Figure 4 and Figure 5 The reciprocating mechanism includes a first reciprocating lead screw 16 and a second reciprocating lead screw 14. A fixing plate 19 is fixedly connected to the outer wall of one end of the second main plate 6. A first gear plate 18 and a second gear plate are rotatably connected to the top and bottom of the outer wall of one end of the fixing plate 19, respectively. The first reciprocating lead screw 16 and the second reciprocating lead screw 14 are fixedly connected to the outer wall of one end of the first gear plate 18 and the second gear plate, respectively. A toothed belt 17 is meshed between the outer circumferential walls of the first gear plate 18 and the second gear plate. A first drive motor 5 is fixedly connected to the outer wall of the other end of the second main plate 6. One end of the output shaft of the first drive motor 5 is fixedly connected to the outer wall of the other end of the first gear plate 18.

[0034] Reference Figure 3The first moving block 28 and the second moving block 35 are respectively sleeved on the outer wall of one end of the first reciprocating lead screw 16 and the outer wall of the other end of the second reciprocating lead screw 14. When the first drive motor 5 is started, it can drive the first gear plate 18 to rotate. At this time, under the action of the toothed belt 17, the second gear plate will also rotate at the same time. Therefore, the first reciprocating lead screw 16 and the second reciprocating lead screw 14 will also rotate at the same time. Since the first moving block 28 and the second moving block 35 are threadedly connected to the first reciprocating lead screw 16 and the second reciprocating lead screw 14 respectively, and the first moving block 28 and the second moving block 35 are respectively set at one end of the first reciprocating lead screw 16 and the other end of the second reciprocating lead screw 14, the first moving block 28 and the second moving block 35 will move back and forth in opposite directions at the same time, and drive the fixed copper rod to move back and forth for pulling.

[0035] Reference Figure 1 , Figure 3 and Figure 4 Multiple first position sensors are provided on one side of the outer wall of the second main board 6, and multiple second position sensors are provided on one side of the outer wall of the other side of the third main board 8. Both the first and second position sensors are electrically connected to the second drive motor 22. Since both the first and second position sensors are electrically connected to the second drive motor 22, when the first position sensor detects that the position of the first moving block 28 or the second moving block 35 is close, it will start the second drive motor 22 and cause the docking plate 30 to fix and clamp the copper column. At this time, the first support 25 will descend or the second support will rise. When the second position sensor detects that the position of the first moving block 28 or the second moving block 35 is close, it will cause the second drive motor 22 to rotate in the opposite direction, causing the docking plate 30 to release the copper column. At this time, the first support 25 will rise or the second support will descend. During this process, the lateral movement of the first moving block 28 and the second moving block 35 will not be affected, thereby ensuring the stable operation of the device.

[0036] Reference Figure 1 The first main board 1, the second main board 6 and the third main board 8 all have through holes between their outer walls at both ends, and the other outer wall of the second main board 6 is fixedly connected to both sides of the forming cylinder 4. When the copper column passes through the through hole and the forming cylinder 4, it will be squeezed and shaped by the forming cylinder 4, thereby using the forming cylinder 4 to limit and pull the copper column.

[0037] Reference Figure 1 A control panel 2 is fixedly connected to one end of the outer wall of the first motherboard 1.

[0038] Reference Figure 1 and Figure 2The feeding mechanism includes a first hydraulic cylinder 11, which is fixedly connected to the outer wall of one end of the first main board 1. A push plate 12 is fixedly connected to the piston end of the first hydraulic cylinder 11. Baffles 9 are fixedly connected to both sides of the outer wall of one end of the push plate 12. Two second hydraulic cylinders 13 are fixedly connected to the middle of the outer wall of one end of the push plate 12. A clamping plate 10 is fixedly connected to one end of the piston rod of each of the second hydraulic cylinders 13. A mating hole corresponding to the through hole is opened between the outer walls of both ends of the push plate 12. When the operator feeds the copper column into the forming cylinder 4 through the through hole, the second hydraulic cylinder 13 is activated. The second hydraulic cylinder 13 will drive the clamping plate 10 to move and use the clamping plate 10 and the baffles 9 to fix the copper column. At this time, the first hydraulic cylinder 11 is activated, and the fixed copper column is directly squeezed into the forming cylinder 4, causing the copper column to extend out of the second main board 6, thus realizing the automatic feeding effect of the copper column.

[0039] Working principle: When the operator inserts the copper column into the forming cylinder 4 through the through hole, the second hydraulic cylinder 13 is activated. The second hydraulic cylinder 13 drives the clamping plate 10 to move, and the clamping plate 10 and the baffle plate 9 fix the copper column. At this time, the first hydraulic cylinder 11 is activated, directly squeezing the fixed copper column into the forming cylinder 4, causing the copper column to extend out of the second main plate 6. When the copper rod passes through the second main plate 6, the second drive motor 22 is activated and drives the first bidirectional threaded rod 31 and the second bidirectional threaded rod to rotate. At this time, the first moving plate 34 and the second moving plate will move in the same direction or in opposite directions under the action of the first bidirectional threaded rod 31 and the second bidirectional threaded rod. When the first moving plate 34 or the second moving plate moves towards each other, it will drive the docking plate 3. The copper pillar passing through the second main board 6 is clamped in place. When the first moving plates 34 approach each other and are about to clamp the copper pillar, the inner rod 32 is gradually pulled out from the air rod 21, reducing the pressure in the air rod 21. This reduces the pressure in the first cylinder 20, causing the first lifting block 26 to lower the first support 25, thus clamping the copper pillar. Conversely, the first lifting block 26 raises the first support 25. When the second moving plates approach each other, the inner rod 32 is also gradually pulled out from the air rod 21, reducing the pressure in the second cylinder. Under this pressure, the second lifting block is lifted upwards by the second cylinder, allowing the other connecting plates 30 to clamp the copper pillar. Conversely, the second lifting block lowers. This ensures that the several mating plates 30 do not interfere with each other when moving laterally. When the first drive motor 5 starts, it can drive the first gear plate 18 to rotate. At this time, under the action of the toothed belt 17, the second gear plate will also rotate simultaneously. Therefore, the first reciprocating screw 16 and the second reciprocating screw 14 will also rotate simultaneously. Since the first moving block 28 and the second moving block 35 are threadedly connected to the first reciprocating screw 16 and the second reciprocating screw 14 respectively, and the first moving block 28 and the second moving block 35 are respectively set at one end of the first reciprocating screw 16 and the other end of the second reciprocating screw 14, the first moving block 28 and the second moving block 35 will simultaneously perform reciprocating movements in opposite directions, and drive the fixed copper rod to reciprocate for pulling. Due to the first position Both the first position sensor and the second position sensor are electrically connected to the second drive motor 22. Therefore, when the first position sensor detects that the position of the first moving block 28 or the second moving block 35 is close, it will start the second drive motor 22 and cause the docking plate 30 to clamp the copper column. At this time, the first support 25 will descend or the second support will rise. When the second position sensor detects that the position of the first moving block 28 or the second moving block 35 is close, it will cause the second drive motor 22 to rotate in the opposite direction, causing the docking plate 30 to release the copper column. At this time, the first support 25 will rise or the second support will descend. During this process, the lateral movement of the first moving block 28 and the second moving block 35 will not be affected, thus ensuring the stable operation of the device.
