Specific embodiments

[0022] The following combines the accompanying drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0023] "Top surface", "bottom", "bottom surface" are referenced based on the normal use state of the pipe bending equipment, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model.

[0024] As Figure 1 and 2 shown, a pipe bending equipment for the production of an electric vehicle frame includes a machine base 1. A propulsion mechanism 101 for conveying pipes is slidably arranged on the top surface of the machine base 1 along the first direction. A two-axis moving table 102 is arranged at the front end of the machine base 1, and a motor 2 is fixedly connected to the moving end of the two-axis moving table 102; the motor 2 has a rotating shaft 201 extending vertically. The rotating shaft 201 is provided with a rotating base 3 and a plurality of bending discs 4 distributed coaxially. Each bending disc 4 is distributed along the axial direction of the rotating shaft 201, and the radius of each bending disc 4 gradually decreases upward along the vertical direction; the rotating base 3 is connected to a clamping block 5 through a moving mechanism 6, and the clamping block 5 cooperates with the bending disc 4 to clamp the end of the pipe.

[0025] The above-mentioned elbow pipe equipment is applicable to the bending operation of the pipe materials of an electric vehicle frame. The propulsion mechanism 101 includes a clamp for clamping the pipe material, a rotating motor for driving the clamp to rotate around the axis of the pipe material, and a moving trolley for driving the clamp to move axially along the pipe material, so as to realize the clamping, propulsion and rotation of the pipe material; grooves are provided on the outer periphery of the bending disc 4 and the clamping block 5. The pipe material is placed in the groove of the bending disc 4, and the clamping block 5 is driven to move by the moving mechanism 6, so that the clamping block 5 and the bending disc 4 cooperate to clamp the pipe material. The bending disc 4 and the clamping block 5 are driven to rotate synchronously around the rotating shaft 201 by the motor 2. The motor 2 can be integrated with a gearbox to improve the torque output of the motor 2, so that the pipe material is wound around the outer periphery of the bending disc 4, and finally the bending operation of the pipe material is realized; when it is necessary to bend the pipe material into arcs with different radii, first the clamping block 5 and the bending disc 4 loosen the pipe material, and the two-axis translation stage 102 drives each bending disc 4 to move in the vertical plane, so that the pipe groove is placed in the grooves of the bending discs 4 with different radii. The moving mechanism 6 drives the clamping block 5 to abut and cooperate with the bending disc 4 to clamp the pipe material, and then the bending disc 4 and the clamping block 5 are driven to rotate by the motor 2, so as to realize the bending of the pipe material. Since the bending arc of the pipe material is determined by the radius of the bending disc 4, multiple bending discs 4 with different radii can provide multiple different bending radii for the pipe material to improve the bending effect of the bending equipment on the pipe material.

[0026] Multiple bending discs 4 are stacked in sequence from bottom to top, and the radii gradually decrease, so that each bending disc 4 can form a structure similar to a cone, and only one movable clamping block 5 is provided. In this way, the space around the bending disc 4 can be occupied less, which is convenient for accommodating the bent pipe material. At the same time, the setting of a single clamping block 5 can also prevent interference between the clamping block 5 and the pipe material, which is convenient for bending the pipe material; and the clamping block 5 can be completely staggered with each bending disc 4, which can prevent the pipe material from getting stuck between the clamping block 5 and the bending disc 4.

[0027] A further improvement is that, as Figure 3 shown, an installation sleeve 301 is integrally formed at the top end of the rotating seat 3, and a reinforcing sleeve 303 is fixedly connected to the bottom end of the rotating seat 3 by bolts. The motor 2 is located between the installation sleeve 301 and the reinforcing sleeve 303. Both the installation sleeve 301 and the reinforcing sleeve 303 are coaxially sleeved on the outer periphery of the rotating shaft 201, and a thrust bearing 302 is provided between the installation sleeve 301 and the top end of the motor 2. The installation sleeve 301 and the reinforcing sleeve 303 realize the two-point connection between the rotating seat 3 and the rotating shaft 201, improving the firmness of the connection between the two; the reinforcing sleeve 303 and the rotating seat 3 can be disassembled, and then the disassembly between the rotating seat 3 and the rotating shaft can be realized, improving the convenience of equipment maintenance; the setting of the thrust bearing 302 can reduce the friction between the installation sleeve 301 and the motor 2, reduce the mutual wear between the two, and at the same time improve the smoothness of the rotation of the rotating seat 3.

[0028] A further improvement is that, as Figure 2 shown, the top end of the rotating shaft 201 has a threaded section 202, and a fastening nut 204 is threadedly connected to the threaded section 202. Each bending disc 4 is located between the mounting sleeve 301 and the fastening nut 204. The setting of the fastening nut 204 is used to fasten the mounting sleeve 301 and each bending disc 4, improving the firmness of the installation of the mounting sleeve 301 and each bending disc 4; at the same time, the setting of the fastening nut 204 also facilitates the disassembly between the mounting sleeve 301 and each bending disc 4 and the rotating shaft 201, so that more bending discs 4 with different radii can be replaced on the rotating shaft 201, providing more bending radii according to production requirements and improving the practicability of the bending equipment; and different-sized bending discs 4 can also be replaced according to the pipe diameter of the pipe, enabling the bending equipment to be applicable to the processing of pipes with different diameters.

[0029] A further improvement is that, as Figure 2 and 3 shown, a positioning through groove 203 is axially formed on one side of the rotating shaft 201, and positioning keys 305 matching the positioning through groove 203 are arranged on the inner walls of the mounting sleeve 301 and each bending disc 4. The positioning through groove 203 and the positioning keys 305 cooperate with each other to prevent slipping between the mounting sleeve 301 and the bending disc 4 and the rotating shaft 201, improving the firmness of the connection between each component and the rotating shaft 201.

[0030] A further improvement is that, as Figures 3 - 5 shown, the moving mechanism 6 includes a lifting hydraulic cylinder 601 vertically arranged on the rotating seat 3. The lifting end of the lifting hydraulic cylinder 601 is fixedly connected with a lifting seat 602. A transverse pushing hydraulic cylinder 605 is arranged on the top surface of the lifting seat 602 along the radial direction of the bending disc 4. The clamping block 5 is detachably connected to the movable end of the transverse pushing hydraulic cylinder 605. The lifting hydraulic cylinder 601 is used to drive the clamping block 5 to lift, and the transverse pushing hydraulic cylinder 605 is used to drive the clamping block 5 to move along the radial direction of the bending disc 4, so that the clamping block 5 can abut against different bending discs 4 to realize the clamping and fixing of the pipe.

[0031] A further improvement is that, as Figure 3 shown, a slot 304 is formed on the top surface of the rotating seat 3, and the lifting seat 602 is slidably matched with the slot 304. The lifting hydraulic cylinder 601 is arranged inside the slot 304. The setting of the slot 304 can play a guiding and limiting role for the lifting seat 602, improving the stability of the lifting seat 602, and further improving the stability of the installation of the clamping block 5 and the firmness of the clamping of the pipe by the clamping block 5.

[0032] A further improvement is that, as Figure 4As shown, a guide sleeve 604 is provided on the top surface of the lifting seat 602 parallel to the radial direction of the bending disc 4. A guide post 603 is slidably and coaxially fitted inside the guide sleeve 604, and the end of the guide post 603 is detachably connected to the clamping block 5. The cooperation of the guide sleeve 604 and the guide post 603 can realize the guiding and positioning functions of the clamping block 5, further improve the stability of the installation of the clamping block 5, and further improve the firmness of the clamping of the pipe by the clamping block 5.

[0033] A further improvement is that, as Figure 5 shown, an installation seat 503 is fixedly connected to the movable end of the horizontal push hydraulic cylinder 605 and the end of the guide post 603. On one of the opposite side surfaces of the installation seat 503 and the clamping block 5, a T-shaped connection groove 501 is provided, and on the other side surface, a connection block 502 matching the connection groove 501 is provided. An anti-slip layer is provided on the surface of the installation seat 503 or the clamping block 5. The cooperation of the connection groove 501 and the connection block 502 can facilitate the disassembly and assembly between the installation seat 503 and the clamping block 5, thereby improving the convenience of disassembly, replacement and installation of the clamping block 5, enabling the clamping block 5 to better match the bending disc 4 and realizing the clamping of pipes with different diameters; the anti-slip layer is a rubber layer, and the setting of the anti-slip layer can increase the friction between the clamping block 5 and the installation seat 503, improve the stability of the connection between the two, prevent the clamping block 5 from falling off during use, and improve the reliability of the operation of the pipe bending equipment.
