Description
Technical Field
[0001] The present application relates to the technical field of bending devices, and in particular to an electrode rod bending device. Background Art
[0002] At present, a spot welder is required for special welding. The spot welder adopts the principle of double-sided double-point overcurrent welding. During operation, two electrodes press on the workpiece, causing a certain contact resistance to form between the two layers of metal under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, instantaneous hot melting is formed at the two contact resistance points, and the welding current instantaneously forms a loop from the other electrode along the two workpieces to this electrode, and the internal structure of the workpiece to be welded will not be damaged.
[0003] When the spot welder is in processing, high-strength electrode rods are required. When the existing bending press bends the electrode rods, the processing components are simply placed on the support blocks of the processing seat. When bending the electrode rods, the electrode rods are prone to sliding, which affects the processing accuracy of the electrode rods. Therefore, further improvement is needed. Summary of the Utility Model
[0004] In order to improve the bending accuracy of the electrode rods, the present application provides an electrode rod bending device.
[0005] The electrode rod bending device provided by the present application adopts the following technical solution:
[0006] An electrode rod bending device includes a workbench, a positioning base provided on the workbench for placing the electrode rods, and a bending mechanism provided on the workbench. The positioning base has a bending cavity, and the positioning base is provided with a pair of connecting shafts passing through the bending cavity. A front support block is rotatably sleeved on one of the connecting shafts, and a rear support block is rotatably sleeved on the other connecting shaft. The front support block and the rear support block are both provided with limiting grooves for the electrode rods to be embedded. A limiting plate for abutting against the front end face of the electrode rod is provided at the front end of the front support block. The bending mechanism includes a bracket, a bending die head located above the positioning base and slidably connected to the bracket vertically to perform a bending operation on the electrode rod, and a driving member for driving the bending die head to slide.
[0007] By adopting the above technical solution, the electrode rods are placed on the front support block and the rear support block, so that the electrode rods are embedded in the limiting grooves, restricting the radial sliding freedom of the electrode rods, and making the front ends of the electrode rods abut against the limiting plate on the front support block, restricting the axial sliding freedom of the electrode rods. The driving member drives the bending die head to press down the electrode rods, causing the electrode rods to be bent under force. At the same time, the front support block and the rear support block rotate with the bending of the electrode rods, and the front support block and the rear support block always support the electrode rods, effectively reducing the possibility of the electrode rods slipping during the bending process and improving the bending accuracy of the electrode rods.
[0008] Preferably, the bending die head includes a connecting block and a pressing head detachably connected below the connecting block. An installation chute is horizontally formed on the lower end surface of the connecting block. An installation slider slidably connected to the installation chute is convexly fixed on the upper part of the pressing head. The connecting block is provided with a limiting member for restricting the sliding of the installation slider.
[0009] By adopting the above technical solution, after the installation slider on the upper part of the pressing head is slidably inserted into the installation chute of the connecting seat, the sliding of the installation slider is restricted by the limiting member, realizing the installation and fixation of the pressing head and the connecting block, which is convenient for replacing damaged or different models of pressing heads.
[0010] Preferably, the installation chute is a dovetail groove, and the installation slider is a dovetail block.
[0011] By adopting the above technical solution, the cooperation of the dovetail groove and the dovetail block makes the connection between the pressing head and the connecting block firm, stable, not easy to loosen, and can also bear a large force.
[0012] Preferably, a first limiting hole is formed on the outer side wall of the installation slider. The limiting member is a limiting bolt threadedly inserted through the outer side wall of the connecting block, and the end of the limiting bolt is embedded in the first limiting hole.
[0013] By adopting the above technical solution, after the installation slider is slidably assembled in the installation chute, the limiting bolt is tightened so that the end of the limiting bolt is embedded in the first limiting hole, realizing the fixation of the pressing head and the connecting block.
[0014] Preferably, a second limiting hole is formed on the outer side wall of the installation slider. The limiting member includes a limiting rod slidably inserted through the connecting block and a spring forcing the end of the limiting rod to slidably insert into the second limiting hole under normal conditions.
[0015] By adopting the above technical solution, before the installation slider is inserted into the installation chute, a force is applied to the limiting rod first, so that the limiting rod slides out of the installation chute. At this time, the spring undergoes elastic deformation and has elastic potential energy, providing a sliding space for the installation slider. Then the installation slider is slid into the installation chute, and the force applied to the limiting rod is removed. When the position of the end of the limiting rod corresponds to the second limiting hole, the spring forces the limiting rod to slide towards the direction close to the installation chute, so that the end of the limiting rod is inserted into the second limiting hole, restricting the relative sliding of the pressing head and the connecting block, and realizing the fixation of the pressing head and the connecting block.
[0016] Preferably, the limiting plate is slidably connected to the front support block along the length direction of the limiting groove, and the front support block is provided with an adjusting component for adjusting the sliding position of the limiting plate.
[0017] By adopting the above technical solution, the sliding position of the limiting plate is adjusted through the adjusting component, so as to adjust the length dimension of the bending head at the front end of the electrode rod.
[0018] Preferably, an adjustment sliding groove is formed in the bottom wall of the limit groove, and an adjustment sliding block slidably connected to the adjustment sliding groove is convexly fixed to the lower part of the limit plate.
[0019] By adopting the above technical solution, the sliding assembly of the limit plate and the front support block is realized through the adjustment sliding groove and the adjustment sliding block.
[0020] Preferably, the adjustment assembly includes an adjustment screw rod rotatably connected to the front support block and a knob coaxially and fixedly connected to the adjustment screw rod, and the adjustment screw rod is threadedly inserted through the limit plate.
[0021] By adopting the above technical solution, the adjustment screw rod is rotated by the knob, and the limit plate is subjected to the thread restriction of the adjustment screw rod for sliding adjustment.
[0022] In summary, the utility model has the following beneficial effects:
[0023] 1. Place the electrode rod on the front support block and the rear support block, so that the electrode rod is embedded in the limit groove, restricting the radial sliding freedom of the electrode rod, and making the front end of the electrode rod abut against the limit plate on the front support block, restricting the axial sliding freedom of the electrode rod. The driving member drives the bending die head to press down the electrode rod, causing the electrode rod to be bent under force. At the same time, the front support block and the rear support block rotate with the bending of the electrode rod, and the front support block and the rear support block always support the electrode rod, effectively reducing the possibility of the electrode rod slipping during the bending process and improving the bending accuracy of the electrode rod;
[0024] 2. After the installation slider at the upper part of the pressing head is slidably inserted into the installation sliding groove of the connecting seat, the installation slider is restricted from sliding by the limiting member, realizing the installation and fixation of the pressing head and the connecting block, which is convenient for replacing damaged or different types of pressing heads;
[0025] 3. Adjust the sliding position of the limit plate through the adjustment assembly, so as to adjust the length dimension of the bending head at the front end of the electrode rod. BRIEF DESCRIPTION OF THE DRAWINGS

The cylinder body of the clamping cylinder 42 is fixedly connected to the upper end surface of the workbench 1, and the axial direction of the piston rod of the clamping cylinder 42 is perpendicular to the sliding direction of the clamping plate 41.
[0036] With reference to Figure 2 、 Figure 3, the positioning side plate 22 is provided with a pair of connecting shafts 24 passing through the bending cavity 23, and the positioning side plate 22 is provided with a plurality of connecting holes 221 for the connecting shafts 24 to pass through. One of the connecting shafts 24 is rotatably sleeved with a front support block 5 located in the pressure cavity, and the other connecting shaft 24 is rotatably sleeved with a rear support block 6 located in the bending cavity 23. The upper end surfaces of the front support block 5 and the rear support block 6 are both provided with limiting grooves 51 for the electrode rod to be embedded, and the front end of the front support block 5 is provided with a limiting plate 52 for the front end surface of the electrode rod to abut against.
[0037] The limiting plate 52 is slidably connected to the front support block 5 along the length direction of the limiting groove 51. Specifically, an adjusting sliding groove 53 is opened on the bottom wall of the limiting groove 51, and an adjusting slider 54 slidably connected to the adjusting sliding groove 53 is convexly fixed at the lower part of the limiting plate 52.

The driving member 33 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is fixedly connected to the bracket 31, and the bending die head 32 includes a connecting block 321 fixedly connected to the lower end of the piston rod of the hydraulic cylinder and a pressing head 322 detachably connected below the connecting block 321 for performing a bending operation on the electrode rod.

[0039] A first limiting hole 325 is opened on the outer side wall of the installation slider 324, and the connecting block 321 is provided with a limiting member 34 for restricting the sliding of the installation slider 324. The limiting member 34 is a limiting bolt threadedly penetrated through the outer side wall of the connecting block 321, and the end of the limiting bolt is embedded in the first limiting hole 325. After the installation slider slides and is assembled in the installation sliding groove 323, the end of the limiting bolt is embedded in the first limiting hole 325 by tightening the limiting bolt, so as to realize the fixation of the pressing head 322 and the connecting block 321.
[0040] The implementation principle of a bending device for an electrode rod in an embodiment of this application is as follows: Place the electrode rod on the front support block 5 and the rear support block 6, such that the electrode rod is embedded in the limiting groove 51 to restrict the radial sliding freedom of the electrode rod, and the front end of the electrode rod abuts against the limiting plate 52 on the front support block 5 to restrict the axial sliding freedom of the electrode rod.

[0041] Embodiment 2:
[0042] The difference from Embodiment 1 is that, referring to Figure 5 , a second limiting hole 326 is formed in the outer side wall of the mounting slider 324.

The spring 342 is located outside the connecting block 321, the spring 342 is sleeved on the limiting rod 341, a force-applying plate 35 is fixedly connected to the outer end of the limiting rod 341, one end of the spring 342 is fixedly connected to the outer wall of the connecting block 321, and the other end of the spring 342 is fixedly connected to the force-applying plate 35.
[0043] Before installing the mounting slider 324 into the mounting chute 323, first apply a force to the limiting rod 341 to cause the limiting rod 341 to slide out of the mounting chute 323. At this time, the spring 342 undergoes elastic deformation and has elastic potential energy. After providing a sliding space for the mounting slider 324, slide the mounting slider 324 into the mounting chute 323 and remove the force applied to the limiting rod 341. When the position of the end of the limiting rod 341 corresponds to that of the second limiting hole 326, the spring 342 forces the limiting rod 341 to slide towards the direction close to the mounting chute 323, so that the end of the limiting rod 341 is inserted into the second limiting hole 326, restricting the relative sliding of the pressing head 322 and the connecting block 321, and realizing the fixation of the pressing head 322 and the connecting block 321.
[0044] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby.
