Description

Technical Field

[0001] The invention relates to the technical field of copper rod drawing, in particular to a drawing machine for copper rod processing. Background Art

[0002] Drawing machine is an industrial equipment composed of mechanical equipment, lubrication equipment, electrical equipment, hydraulic and pneumatic systems, etc. It is a device for drawing metal materials. Copper rod is a non-ferrous metal rod. Copper has high conductivity and is widely used. The drawing machine is used to draw metal at room temperature. Therefore, it is usually used to reprocess copper rods so that they can be longer and change the diameter of copper rods to meet the required diameter requirements.

[0003] At present, the existing equipment for drawing copper rods is mainly divided into chain drawing machines, hydraulic drawing machines, and drum drawing machines. Since the equipment needs to go back and forth to draw the copper rod, in actual use, when the length of the copper rod is long, generally one round trip cannot achieve complete drawing of the copper rod, and when the drawing amount is large, a single drawing forming is easy to damage the copper rod, so multiple drawing is required. Therefore, the copper rod is clamped and drawn multiple times after the equipment returns. During this process, the copper rod will be intermittently paused, and when it is suddenly stressed again, it is easy to cause the copper rod to break.

[0004] This case was created to solve the above problems. Summary of the invention

[0009] As a preferred solution, further, the driving source is a cylinder arranged at the bottom of the frame 2, the output end of the cylinder is hinged with a connecting block, and the upper side of the connecting block is hinged to the bottom of the conductive seat to indirectly drive the clamping seat to move back and forth horizontally.

[0010] As a preferred embodiment, the conductive seat is hollow inside and has a through hole formed in the middle. An annular sleeve is provided at the front through hole of the conductive seat. The rear end of the annular sleeve is connected to the inner wall of the conductive seat through a support rod. The rear side of the forming cylinder is connected to an annular fitting sleeve. The size of the fitting sleeve matches the size of the annular sleeve so that it can be inserted into the outer wall of the annular sleeve, wherein the length of the copper rod pulled once is the length of the fitting sleeve.

When the conductive seat contacts the left electric contact switch, the electromagnet in the limiting seat is de-energized, and the electromagnet in the clamping seat is energized.

DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] See attached Figure 1 As shown, a copper rod processing drawing machine includes a frame 1, on which a traction assembly 13 and a traction assembly 24 for traction of a copper rod 5 are arranged, and the two traction assemblies 13 and 24 are respectively carried out in the horizontal and longitudinal directions, and a straightening effect is achieved to a certain extent. The traction assembly 13 includes an adjustment seat 241, a moving seat 242, and a transverse traction wheel 43. The adjustment seat drives the moving seat 242 to move horizontally by a screw rotation drive mode, and the inner side of the moving seat is connected to a plurality of transverse traction wheels 43, and a plurality of fixed transverse traction wheels 43 are arranged on one side of the moving seat interval (one of the transverse traction wheels 43 is provided with a driving motor), and the traction of the copper rod 5 is achieved by adjusting the spacing between the transverse traction wheels 43 on both sides. The traction assembly 24 has the same structure as the traction assembly 13, and only the horizontal position is rotated to the vertical position.

[0029] A guide roller 6 is arranged near the side of the frame 1, and the guide roller 6 is fitted to the side of the copper rod 5 to assist the copper rod 5 to conduct smoothly.

[0030] The frame 1 is adjacent to the frame 2 2 on the other side along which the copper rod 5 is pulled. The frame 2 2 is sequentially provided with a forming cylinder 7, a conducting seat 8, and a clamping seat 10. The conducting seat 8 passes through a long groove 15 which is slidably connected to the upper end surface of the frame 2. The conducting seat 8 is adjacent to the clamping seat 10 and is axially connected. A cylinder 12 is arranged at the bottom of the frame 2. A connecting block 17 is hinged at the output end of the cylinder 12. The upper side of the connecting block 17 is hinged to the bottom of the conducting seat 8 to indirectly drive the clamping seat 10 to move back and forth horizontally. The forming cylinder 7 is placed at the farthest end of the clamping seat 10.

[0031] The limiting seat 11 is located at the output end of the copper rod 5 and is fixed to the frame 2 2. A connecting rod 2 13 and a connecting rod 1 14 which are hinged to each other are provided between the limiting seat 11 and the clamping seat 10. The outer sides of the connecting rod 2 13 and the connecting rod 1 14 are hinged to the limiting seat 11 and the clamping seat 10 respectively.

[0032] See attached Figure 2 As shown, the conductive seat 8 is hollow inside and has a through hole in the middle. An annular sleeve 18 is provided at the position of the through hole on the front side of the conductive seat 8. The rear end of the annular sleeve 18 is connected to the inner wall of the conductive seat 8 through a support rod 19 so as to be suspended in the through hole. An annular fitting sleeve 9 is connected to the rear side of the forming cylinder 7. The size of the fitting sleeve 9 is adapted to the size of the annular sleeve 18 so as to be able to fit and insert into the outer wall of the annular sleeve 18. The length of the copper rod 5 drawn once is the length of the fitting sleeve 9.

[0033] See attached Figure 3-4 As shown, the clamping seat 10 is in a hollow cone shape, and its front side is small and its rear side is large. A guide seat 20 is installed circumferentially on the inner wall of the clamping seat 10, and a guide block 21 is slidably connected to the inner side of each guide seat 20, wherein the bottom of the guide seat 20 is flush with the wall surface of the clamping seat 10, and the bottom of the guide block 21 is horizontal, so as the guide block 21 gradually moves forward, the height of its bottom gradually drops toward the central axis until it fits and clamps the inserted copper rod 5.

[0034] Since the moving block is entirely located inside the clamping seat 10, it is driven by electromagnetic means. A front block 23 is connected to the rear side of each guide block 21, and a ring-shaped rear block 24 is connected to the rear side of the clamping seat 10. A permanent magnet is placed on the rear side of the front block 23, and an electromagnet is placed at the rear block 24 corresponding to the front block 23. When the electromagnet is energized, it has the same magnetic property as the permanent magnet to repel it from moving forward.

[0035] In order to ensure that the circumferential guide block 21 can better clamp the copper rod 5 and prevent it from falling off, a friction pad 22 is arranged at the bottom thereof to increase friction and prevent slipping.

[0036] It should be noted that, except for the different fixed positions and sizes, the internal structure of the limiting seat 11 is the same as that of the clamping seat 10 .

[0037] Combined with Figure 5-6As shown, this solution designs an external circuit for the energization of the electromagnets inside the limiting seat 11 and the clamping seat 10, and realizes the on and off of the electromagnets in the corresponding clamping seat 10 and the limiting seat 11 according to the movement process of the conductive seat 8, so as to achieve automation and high-sensitivity feedback, and play an instant clamping and pulling role to avoid sudden force on the copper rod 5. The displacement section (b->a) of the movable clamping seat 10 moving forward is set as y1, and the displacement section (b->c) moving backward is set as y2. A circuit is set in the displacement sections y1 and y2 respectively, and electric contact switches are set at the ends of the two displacements (the circuit is disconnected at the switch that is touched, and the other circuit forms a passage). Taking the attached figure as an example, when the conducting seat 8 contacts the left electric contact switch, the electromagnet in the limiting seat 11 is de-energized, and the electromagnet in the clamping seat 10 is energized. At this time, the subsequent movement of the conducting seat 8 is the displacement section (b->c) moving backward, that is, the guide block 21 in the clamping seat 10 clamps the copper rod 5 and moves backward to pull the copper rod 5, and at the same time, the guide block 21 in the limiting seat 11 instantly loosens the clamping force on the copper rod 5. On the contrary, the guide block 21 in the clamping seat 10 loosens the clamping force on the copper rod 5 and moves forward to the front end to restore, and at the same time, the guide block 21 in the limiting seat 11 instantly clamps the copper rod 5 on the central axis. The guide seat 20 realizes multiple pulling of the copper rod 5 during the reciprocating switching of y1 and y2, and during the multiple and intermittent pulling process, the copper rod 5 is always subjected to the pulling force, and the copper rod 5 will not break due to sudden force pulling again.

[0038] Specifically, electric contact switches are respectively arranged at both ends of the fitting sleeve 9 , and an electric contact point is arranged at the front side of the annular sleeve 18 .

[0039] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
