Description

Technical Field

[0001] The invention relates to the technical field of copper rod processing, in particular to a continuous automatic cutting device for copper rod production. Background Art

[0002] Copper rod is a rod-shaped object made of copper and zinc alloy, named for its yellow color, and is mostly used in air conditioning pipes, refrigerator pipes, oil pipes, water supply pipes and automobile synchronizer gear rings. Usually, if the copper rod is a hollow cylindrical structure, the hollow brass rod with low hardness is easy to deform during its cutting process, which is not conducive to cutting and affects the forming of the brass rod.

[0003] For example, the application number is 201911296109.3, and is named "Cutting device for brass rods". A limit column is provided to facilitate the positioning of the brass rod. On the other hand, when the brass rod is subjected to force, it is supported by the limit column, so the brass rod will not be deformed, thereby improving the cutting accuracy and facilitating the cutting of the brass rod. Secondly, the outer surface of the limit column is used to fit with the inner surface of the brass rod, and the outer surface of the limit column is provided with anti-slip grooves to increase the friction between the limit column and the brass rod.

[0004] However, the cutting method is to complete a one-time cutting from the upper side all the way down, which has a problem, that is, when the cutting knife continuously cuts the copper rod downward, the cut surface of the copper rod will continue to contact with the cutting knife, and the copper rod and the cutting knife of the cut surface are both at high temperature, which can easily make the surface layer of the copper rod cross section melt into slag and stick to the surface, and stick to the surface of the cutting knife to a certain extent, making the post-processing process more cumbersome, and when the cutting knife contacts the cross section of the copper rod, it will increase the vibration force, causing the cutting progress of the copper rod to be further affected.

DETAILED DESCRIPTION

[0028] 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.

[0029] See attached Figure 1-3 As shown, a continuous automatic cutting device for copper rod production is used for cutting hollow cylindrical brass rods 2, including a base 1, a feed support 13 is fixed on the base 1 for supporting the copper rod 2 to be cut, and a clamping rod 3 is provided on the base 1, the front side of the clamping rod 3 can penetrate into the copper rod 2, and the copper rod 2 is tightened by multiple radial outward forces. A mobile bracket 21 is provided on the base 1, and a cutting mechanism is provided on the front side of the mobile bracket 21, and the rear side is connected to the end of the clamping rod 3, wherein the cutting mechanism and the clamping rod 3 are offset. The cutting position of the cutting mechanism is close to the clamping front end position of the clamping rod 3, so that the copper rod 2 can be stably supported and limited at the cutting position, reducing vibration and displacement during cutting.

[0030] The cutting mechanism comprises a conventional cutting knife seat 6, the upper side of which is connected to a cylinder 25 supported on a movable bracket 21, and a cutting knife 7 is arranged on a cutting guide seat and driven by a motor.

[0031] The clamping rod 3 includes a hollow long rod, in which a conventional three-claw cylinder 23 is arranged. The outer sides of the three claws at the output end of the three-claw cylinder 23 are connected to an arc-shaped clamping block, and a through groove 22 adapted to the size of the clamping claw is opened at the corresponding part of the long rod. Anti-slip grooves can be set on the outer side of the clamping block to increase the contact friction with the copper rod 2, thereby realizing reinforced limiting.

[0032] That is, by forming a limit support at the inner side of the copper rod 2, since the entire inner wall or outer wall of the copper rod 2 is circular in cross section, it is still loose after clamping, and the fixing effect is generally poor. Therefore, in this embodiment, a layer is coated on the outer side of the front side of the long rod or the body is made of iron material, and an electromagnet is set on the inner periphery of the feeding support 13 supporting the copper rod 2 at the outer side. When cutting, the electromagnet is energized synchronously, so that the outer tightening force is applied to the copper rod 2, forming a secondary reinforcement limit.

[0033] The rear end of the mobile bracket 21 is driven by a horizontally arranged cylinder 18, which is located at the bottom of the base 1, and its output end is connected to a connecting block 19, which passes through a long slot 12 opened on the base 1, and its front side is connected to the mobile bracket 21 through a connecting rod 11. The forward movement between movements is achieved through the recovery process of the cylinder 18 to adjust the cutting position of the cutting mechanism corresponding to the copper rod 2. Secondly, a sliding wheel is connected to the side of the mobile bracket 21 through a shift rod 15, and the sliding wheel is slidably connected to a slide groove 16 axially opened on the base 1.

[0034] The front end of the base 1 is provided with a stopper 14, wherein the stopper 14 is hinged to the base 1, and when the stopper 14 is pushed forward, it gradually rotates downward to a horizontal position, so as to realize rapid material unloading. Secondly, a coil spring is provided at the hinge position between the stopper 14 and the base 1, so that the stopper 14 can rebound to its original position when no force is applied, and can block the copper rod 2 to a certain extent to prevent it from falling due to no external force.

[0035] Furthermore, considering that the conventional cutting method is to complete a one-time cutting from the upper side all the way down, there is a problem, that is, when the cutting knife 7 continuously cuts the copper rod 2 downward, the cut section of the copper rod 2 will continue to contact the cutting knife 7, and the copper rod 2 and the cutting knife 7 of the cut section are both at high temperature, which can easily cause the surface layer of the copper rod 2 section to melt into slag and stain the surface, and to a certain extent stain the surface of the cutting knife 7, making the post-processing process more cumbersome, and when the cutting knife 7 contacts the cross-section of the copper rod 2, the vibration force will increase, causing the cutting progress of the copper rod 2 to be further affected.

[0036] Therefore, in this embodiment, the long rod is supported and fastened on the inner side, and at the same time, it can be linked to drive the copper rod 2 to rotate, so that the cutting knife 7 is always in contact with the surface to be cut of the copper rod 2 and avoids contact with the cut surface, thereby increasing the cutting efficiency and reducing the force and vibration of the copper rod 2 during the cutting process.

[0037] Specifically, as attached Figure 4 As shown, the rear end of the long rod is connected to a thin rod 24, which is pivotally connected to the connection of the movable bracket 21 and is sleeved with a gear 10. The movable bracket 21 is also connected to an extension rod 17, and a motor 8 is installed on the lower side of the extension rod 17. The output end of the motor 8 is connected to a gear 2 9 meshing with the gear 10, thereby driving the long rod to rotate (the electromagnet needs to be powered off during the rotation process).

[0038] The cutting device of this embodiment can also realize automatic loading and unloading of materials, and realize the automation process of the entire cutting process. For details, see the attached Figure 2As shown, a feeding mechanism 4 is provided on one side of the base 1, and the feeding mechanism 4 includes a machine table 41, on which two interval rollers are pivotally connected, and a conveyor belt 43 is wrapped and sealed, one of the rollers is driven by a large motor 428 as an active roller, and blocks 44 are installed on the conveyor belt 43 at intervals, and a copper rod 2 is placed between two adjacent blocks 44. A guide plate 45 arranged obliquely downward is installed on the front side of the machine table 41, and an inclined surface 20 is formed on the upper end of the feed support 13 adjacent to the guide plate 45. The inclined surface 20 is connected to the inclined position of the guide plate 45, so that the copper rod 2 can directly roll into the feed support 13. Secondly, the clamping rod 3 can drive the copper rod 2 forward to pass through the block seat 14 to the front side where the gravity is greater, so that when the clamping rod 3 (i.e., the long rod) is retracted and separated from the copper rod 2, the copper rod 2 falls off the base 1 due to gravity, and the copper rod 2 is unloaded.

[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.
