Description

Technical Field

[0001] The invention relates to the technical field of extrusion equipment, in particular to an intelligent copper bar extrusion device capable of continuous production. Background Art

[0002] As we all know, the extrusion device is a processing equipment that extrude alloy profiles such as tubes, rods, and plates to make them undergo plastic deformation. There are many types of extrusion devices, and the capacity and number of extrusion devices can reflect the production technology level of an enterprise.

[0003] Copper busbar, also known as copper busbar or copper busbar, is made by directly extruding copper material through an extrusion device and causing the copper material to undergo plastic deformation. Copper busbar plays the role of transmitting current and connecting electrical equipment in the circuit. Copper busbar has been widely used in electrical equipment, especially complete sets of power distribution equipment.

[0004] When a traditional extrusion device is in use, a motor drives one of the extrusion rollers on the extrusion device to actively rotate, and the other extrusion roller is in an unloaded state. When the copper material is transported between the two extrusion rollers, the extrusion roller in the actively rotating state drives the copper material to be transported between the two extrusion rollers, and the copper material drives the unloaded extrusion roller to rotate. The two extrusion rollers synchronously extrude and deform the copper material, thereby deforming the copper material into a finished copper bar. However, when using such equipment, since one of the two extrusion rollers is in an actively rotating state and the other is in a driven rotating state, the friction force generated by the extrusion roller in the actively rotating state on the copper material and the friction force generated by the extrusion roller in the driven rotating state on the copper material are in opposite directions, resulting in uneven force on the upper and lower surfaces of the copper material, resulting in a large difference in density after the upper and lower sides of the copper material are extruded and deformed, which is easy to affect the normal conductivity of the copper material and result in poor processing quality of the copper bar.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of the present invention, it should be noted that, 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 integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0027] like Figure 1 As shown, an intelligent copper bar extrusion device capable of continuous production of the present invention comprises two base plates 1 distributed up and down, two support slot plates 2 are vertically arranged between the two base plates 1, two extrusion rollers 3 are arranged between the two support slot plates 2, the two extrusion rollers 3 are distributed up and down, connecting shafts 4 are fixed at both ends of the extrusion rollers 3, a slider 5 is rotatably arranged at the outer end of the connecting shaft 4, and the slider 5 is arranged in the support slot plate 2;

[0028] A worm gear 6 is installed on the outer wall of a connecting shaft 4 on the squeezing roller 3, and worms 7 are arranged on the front and rear sides of the squeezing roller 3. The worm gear 6 on each squeezing roller 3 is located between two worms 7, and the two worm gears 6 are meshed and connected with the two worms 7 respectively.

[0029] In this embodiment, since the two worm wheels 6 are respectively meshed with the two worms 7, one worm 7 drives one worm wheel 6 to rotate, synchronizing the two worms 7, and the rotation directions of the two worms 7 are opposite, so that the two worm wheels 6 rotate synchronously, and the rotation directions of the two worm wheels 6 are opposite, the two worm wheels 6 drive the two extrusion rollers 3 to rotate synchronously in the opposite direction. When the copper bar needs to be extruded, the copper material is transported between the two extrusion rollers 3, and the two extrusion rollers 3 in the synchronous opposite rotation state extrude the upper and lower surfaces of the copper material at the same time, and the friction forces of the two extrusion rollers 3 on the upper and lower surfaces of the copper material are kept in the same direction, so as to facilitate the copper bar to be extruded. The upper and lower surfaces of the material are kept in a synchronous plastic deformation state, so as to avoid differences in the amount of plastic deformation and deformation direction of the upper and lower surfaces of the copper material due to the different directions of the friction forces of the two extrusion rollers 3 on the upper and lower surfaces of the copper material. The copper material is extruded and deformed by the two extrusion rollers 3 to generate a copper bar. By making the two extrusion rollers 3 synchronously and actively extrude the copper material, the friction forces on the upper and lower surfaces of the copper material can be balanced, and the directions of the friction forces can be kept consistent, so that the force on the copper material can be kept uniform, thereby facilitating the balance of the internal density of the copper material, avoiding the influence of excessive differences in the internal density of the processed copper bar on the normal conductive work of the copper bar, and effectively improving the processing quality of the copper bar.

[0030] like Figures 1 to 3 As shown, as a preferred embodiment of the above embodiment, the slider 5 is slidably connected to the support slot plate 2, a spur gear 8 is arranged between the two sliders 5 in the support slot plate 2, and two gear rows 9 are meshed on the spur gear 8, one end of the gear row 9 is fixed on a slider 5 in the support slot plate 2, and the other end of the gear row 9 passes through the other slider 5 and is slidably connected, and a first motor 10 is installed on the outer wall of the support slot plate 2, and the first motor 10 is transmission-connected to the spur gear 8.

[0031] In this embodiment, the first motor 10 drives the two tooth rows 9 to move synchronously in opposite directions through the spur gear 8. The two tooth rows 9 respectively drive the two sliders 5 in the supporting slot plate 2 to move synchronously in opposite directions, thereby adjusting the distance between the two extrusion rollers 3, which is convenient for extrusion processing of copper bars with different thickness requirements. At the same time, the two extrusion rollers 3 keep moving synchronously, so as to facilitate the synchronous movement of the two worm wheels 6 on the two worm screws 7, so that when the two extrusion rollers 3 move synchronously, their rotation speeds always remain consistent, so as to avoid the situation where only one extrusion roller 3 is moved, the worm wheel 6 is in a moving state on the worm screw 7, and the transmission ratio of the worm wheel 6 and the worm screw 7 changes, resulting in a difference in the rotation speed of the two extrusion rollers 3.

[0032] like Figure 3 As shown, as a preferred embodiment of the above embodiment, a guide column 11 is provided on the slider 5, the guide column 11 passes through the slider 5 and is slidably connected, the outer end of the guide column 11 is fixed on the base plate 1, and a spring 12 is sleeved on the outer wall of the guide column 11, one end of the spring 12 is fixed on the base plate 1, and the other end of the spring 12 is fixed on the slider 5.

[0033] In this embodiment, the guide column 11 can guide the slider 5 in a moving state, and the spring 12 is in a compressed and deformed state. The spring 12 generates an auxiliary elastic thrust on the slider 5, thereby reducing the force of the extrusion roller 3 on the tooth row 9 when the extrusion roller 3 extrudes and deforms the sheet material, thereby facilitating the protection of the spur gear 8, the tooth row 9 and the first motor 10, and reducing the strength of the first motor 10 to withstand the group force.

[0035] In this embodiment, the second motor 14 drives the two bevel gears 16 to rotate synchronously through the transmission wheel 15. The two bevel gears 16 rotate in opposite directions. The two bevel gears 16 drive the two worms 7 to rotate synchronously in opposite directions, thereby driving the two squeezing rollers 3 to rotate.

At the same time, the copper material and the copper bar can respectively drive the two rollers 17 at the corresponding positions to rotate. By setting up the Z-shaped baffle 19, the copper material or copper bar on the roller 17 can be conveniently limited and shielded, and the copper material and the copper bar are conveyed between the Z-shaped baffle 19 and the roller 17.

[0038] like Figure 4As shown, as a preferred embodiment of the above embodiment, two air guide tubes 20 and two vertical plates 22 are further included.

[0039] It also includes a three-way pipe 24 , the input end of the three-way pipe 24 is connected to an external air pump, and the two output ends of the three-way pipe 24 are connected to two air guide pipes 20 .

[0040] In this embodiment, air is pumped into the two air ducts 20 through the three-way pipe 24, and the air in the air duct 20 is discharged to the surface of the copper material through the nozzle 21, so as to perform aeration cleaning on impurities such as dust and particles deposited on the upper and lower surfaces of the copper material to avoid the impurities from affecting the extrusion of the copper material. The vertical plate 22 and the second mounting frame 23 can support the air duct 20.

The eccentric wheel 25 is transmission-connected to the roller 17 on the feeding side between the two extrusion rollers 3, and the eccentric wheel 25 is eccentrically connected to the roller 17.

[0042] In this embodiment, when the copper material is conveyed, the copper material drives the roller 17 to rotate, the roller 17 drives the eccentric wheel 25 to rotate eccentrically, the eccentric wheel 25 drives the push-pull ring 26 to swing eccentrically, the push-pull ring 26 pushes the connecting plate 28 to move back and forth through the push-pull rod 27, the connecting plate 28 drives the air guide tube 20 to slide back and forth on the vertical plate 22, the air guide tube 20 guides the connecting plate 28, so that the multiple nozzles 21 on the air guide tube 20 are in a swinging jet state, which makes it convenient for the air sprayed by the multiple nozzles 21 on the air guide tube 20 to fall fully on the surface of the copper material, thereby facilitating a comprehensive aeration cleaning treatment of the copper material.
