Description

Technical Field

[0001] The invention discloses a rare earth high iron aluminum alloy conductor rod manufacturing device and process, belonging to the field of cable equipment. Background Art

[0002] In the process of wire manufacturing, rod drawing (or drawing) is an important process step. Through the drawing process, the diameter of the wire core material (such as copper, aluminum, etc.) can be reduced while increasing its length.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] In the existing drawing process, due to jitter or insufficient mechanical precision, chatter marks or surface defects may occur on the drawn material, thus affecting the quality and appearance of the product. After long-term use, the precision of the equipment may decrease, resulting in poor pressing or drawing effects. Therefore, in order to solve the above problems, this case proposes the following technical solutions:

[0043] See also Figures 1 to 7 The present invention provides a rare earth high-iron aluminum alloy conductor rod manufacturing equipment and process technology solution: its structure includes: a pulling cart 1, a frame 2 is provided at the bottom of the pulling cart 1, the pulling cart 1 cooperates with the slide groove on the surface of the frame 2, a trolley 3 is also installed inside the frame 2, the trolley 3 is pushed by a first push rod 4 installed outside the frame 2, a side frame 5 is also installed on the side of the frame 2, a slidable slide arm 6 is provided on the surface of the side frame 5, a pulling cart 1 for driving is provided in the frame 2, the pulling cart 1 includes a clamping mechanism 12 that slides with the frame 2, a guide plate 13 is also installed at the clamping head 124 of the clamping mechanism 12, and a contact structure 11 with a driving belt 7 is provided at the bottom of the clamping mechanism 12, and the contact structure 11 controls the reversing clamping head 112 to move up and down through a commutator 113 to contact the upper and lower belt bodies of the driving belt 7 to change the moving direction.

[0044] When in use, the main structure of the device includes a frame 2, a trolley 3 is installed at the front end of the frame 2, and a first push rod 4 pushes the trolley 3 to push the guide rod into the cutting hole of the frame 2. Then, through the pulling of the pulling trolley 1, the impurities on the surface of the guide rod are removed and leveled by the cutting head inside the frame 2. A side frame 5 is provided on the side of the frame 2, and a rotatable sliding arm 6 is provided on the surface. When the pulling trolley 1 completes the pulling and cutting, the sliding arm 6 rotates the triangular block to guide the guide rod outward along the inclined surface.

[0045] The traction vehicle 1 is pushed by the driving belt 7. The driving belt 7 adopts a chain structure, which can improve the traction force when pulling. The structure of the traction vehicle 1 includes a clamping mechanism 12 for pulling. A contact structure 11 is provided at the bottom of the clamping mechanism 12. The contact structure 11 is used to cooperate with the driving belt 7. The contact structure 11 cooperates with the upper chain of the driving belt 7 to perform the pulling operation, and the contact structure 11 cooperates with the lower chain to retract. During this period, the driving belt 7 is in unidirectional rotation to avoid motor damage caused by frequent forward and reverse rotation. If the motor is reversed too many times, the braking resistance of the motor is increased and the heat generation will also increase.

[0046] The structure of the clamping mechanism 12 includes a base frame 125, a base 122 and a chuck 124 are installed on the surface of the base frame 125, a driving motor 121 is arranged on the top of the base 122, and the driving motor 121 drives the turntable 123 to move the chuck 124 on the surface of the turntable 123, thereby controlling the chuck 124 to perform clamping work.

[0047] A groove is provided at the bottom of the base frame 125 for accommodating the contact structure 11. The contact structure 11 is provided with a top clamping plate 111. The top clamping plate 111 is located in the top groove of the base frame 125. A movable reversing chuck 112 is installed in the middle movable cavity of the top clamping plate 111. A commutator 113 is installed at the bottom of the reversing chuck 112. The reversing chuck 112 is pushed by the commutator 113 to perform switching action.

[0048] A guide plate 13 is installed on the surface of the bottom frame 125, and the guide plate 13 is used to facilitate the guide rod to roll quickly when disengaging.

[0049] The structure of the commutator 113 includes a second push rod 131, which is installed on a bracket formed by a fixed plate 132 and a sliding rod 133. The fixed plate 132 is fixed to the surface of the positioning plate 135 through the sliding rod 133. A push frame 134 is provided on the outer sleeve of the sliding rod 133. The push frame 134 is connected to the main shaft of the second push rod 131. The main shaft of the second push rod 131 pushes the push frame 134 to slide along the surface of the sliding rod 133, thereby pushing the slider 216 to drive the block 211 to translate.

[0050] The positioning plate 135 is nested in the bottom of the base frame 125, and a tooth plate 137 is installed in the inner groove of the positioning plate 135. Second gears 136 are provided on both sides of the tooth plate 137. The second gear 136 can support the driving belt 7 to avoid direct friction with the tooth plate 137 during the rotation and movement of the driving belt 7. At the same time, it is also matched with the top clamping plate 111. The tooth plate 137 and the second gear 136 are symmetrically arranged inside the top clamping plate 111. When the reversing clamp 112 in the middle pushes the driving belt 7 to move upward, the driving belt 7 is attached to the surface of the second gear 136. As the pushing stroke increases, the convex teeth on the surface of the block 211 press the driving belt 7 against the upper or lower chain surface to achieve movement in different directions.

[0051] The structure of the reversing chuck 112 includes a block 211, and limit grooves 217 are designed on both sides of the block 211. The pressure arm 212 is incorporated into the limit grooves 217. The pressure arm 212 is used to fix the gear 213 in contact with the driving belt 7. The support of the gear 213 can reduce noise when the driving belt 7 is idling. Side plates 214 are provided on both sides of the block 211. Through holes are provided inside the side plates 214 to allow the pull rod 151 of the balance bar 215 to penetrate, and the pressure arm 212 and the gear 213 are supported by the spring 152 installed between the side plates of the pressure arm 212 and the balance bar 215. A balance sleeve 153 is provided on the surface of the balance bar 215, and the balance sleeve 153 is used to reduce the friction between the spring 152 and the surface of the side plate 214.

[0052] In addition, a protrusion is provided on the surface of the block 211, which presses the drive belt 7. Through the deceleration of the gear 213, the reversing chuck 112 and the drive belt 7 are meshed and transmitted, thereby reducing friction. Once the rotation speed of the drive belt 7 is faster, the friction force generated can drive the traction vehicle 1 to move slowly as a whole, thereby reducing the friction between the block 211 and the drive belt 7 by means of mobile docking.

[0053] The production process of this equipment is as follows:

[0054] s1: The metal guide rod to be processed is sequentially inserted into the through hole in the middle of the installation position of the first push rod 4, enters the interior of the trolley 3 for clamping, and then passes through the cutting ring in the middle of the frame 2 under the push of the first push rod 4.

[0055] s2: The first push rod 4 pushes the trolley 3 to clean the protruding cutter position on the impurity removal side, and then the driving belt 7 drives the pulling trolley 1 to clamp the metal rod.

[0056] s3: The driving motor 121 drives the turntable 123 inside the base 122 to rotate, so that the clamp 124 moves to clamp the metal rod head.

[0057] s4: The driving belt 7 rotates driven by the motor inside the frame 2, and then the second push rod 131 pushes the fixed plate 132 to press the reversing clamp 112 upward. During the pressing period, the pressing arm 212 is engaged with the driving belt 7. As the pressure increases, the pressing arm 212 is deformed, and the protrusion on the surface of the block 211 presses the driving belt 7 against the surface of the top clamp 111 to perform the pulling work.

[0058] s5: During the pulling process, the sliding arms 6 on the surface of the side frame 5 rotate and open in sequence, so that the triangular block is placed at the bottom of the rod body.

[0059] s6: After the pulling and impurity removal is completed, the driving motor 121 drives the turntable 123 to rotate to loosen the clamp 124, and the rod body rolls along the guide plate 13 and the triangular block unfolded by the side frame 5, and the rod body is transported to the side of the frame 2 for stacking.

[0060] The device drives the pulling cart 1 through the driving belt 7. The contact structure 11 at the bottom of the pulling cart 1 is equipped with a reversing chuck 112 for switching power. The reversing chuck 112 and the top clamping plate 111 at the top and the commutator 113 at the bottom respectively clamp the upper transmission part and the lower transmission part of the driving belt 7. When the upper transmission part is clamped, the metal rod is pulled and removed, and when the lower transmission part is clamped, it is reset. During this period, the friction force of the gear 213 is used to make the pulling cart 1 slowly follow the movement of the driving belt 7, so that the protrusion on the surface of the block 211 can embed the driving belt 7 into the tooth plate 137 for stable limiting, avoiding vibration, making the pulling process more stable, and avoiding damage to the surface of the metal rod.

[0061] Furthermore, the motor driving the driving belt 7 only needs to rotate in the same direction, thereby avoiding heating of the motor caused by forward and reverse braking, which would affect the service life of the motor.

[0062] The above only describes the basic principles and preferred implementations of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present invention.

[0063] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
