Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, and specifically relates to a solder adjustable shearing machine. Background Technique

[0002] At present, the commonly used electrode shearing equipment impacts the electrode intermittently through two impact blocks to achieve the purpose of shearing. In the actual welding operation process, different welding positions have different requirements for the length of the electrode, and there are also differences in the length specifications of the electrodes that need to be sheared for different types of electrodes. Therefore, the electrodes often need to be sheared into different length specifications during the actual shearing process. However, it is very difficult for many current electrode shearing equipments to conveniently adjust the shearing length, which is not conducive to enterprises to improve production efficiency and quickly adapt to market changes.

[0003] The patent document with the publication number of CN221087124U discloses an electrode shearing machine with adjustable shearing length. The conveying mechanism set therein enables the equipment to automatically convey the electrode, avoiding the need to adjust the position of the electrode when manually handling the electrode, saving time and effort, and at the same time reducing the labor intensity of workers. The limiting mechanism set enables the equipment to conveniently adjust the shearing length of the electrode, and electrodes of any length can be sheared according to needs. The adjustment of the shearing length of the electrode is convenient and the shearing efficiency is high.

[0004] The above-mentioned device and technical solution still have some deficiencies in actual application. For example, during the conveying of the electrode by the conveying roller, single or multiple electrodes are prone to linear deflection, which affects the shearing accuracy; at the same time, during the stamping and shearing process, the electrodes on both sides will bounce and swing, further reducing the cutting accuracy of the electrode; and the cut short electrodes will be scattered and roll down due to the loss of restraint, and it is difficult to smoothly pass through the rotating rod and continue to be conveyed backward; therefore, it is necessary to further improve the device on the basis of the existing technology.

Inside the gantry bracket, there is a lifting plate horizontally arranged and driven by a hydraulic device to move up and down. At the center of the bottom of the lifting plate, a main blade is vertically installed. On both sides of the main blade, there are pressing plates horizontally arranged. At the bottom of the pressing plates, there are elastic pads, and the bottom surface of the elastic pads is lower than the bottom surface of the cutting edge of the main blade. An elastic connecting member is connected between the pressing plates and the lifting plate;

[0008] A limit side baffle device is arranged on the upper part of the frame and in the feeding end direction of the gantry bracket, and includes fixed vertical plates fixed on both sides of the upper end of the frame, and limit baffles respectively arranged inside the two fixed vertical plates and capable of relatively sliding and adjusting;

Detailed Embodiment

[0024] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0025] Secondly, the present utility model will be described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0026] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0027] Figures 1 - 3 Shown is the entire structural schematic diagram of a solder-adjustable shearing machine of the present utility model. Please refer to Figures 1 - 3 A solder-adjustable shearing machine according to this embodiment includes a frame 100. Along the length direction of the upper part of the frame 100, there are conveying rollers 110. In the middle of the frame 100, there is a gantry bracket 200. Inside the gantry bracket 200, there is a lifting plate 300 driven by a hydraulic device to move up and down horizontally. At the center of the bottom of the lifting plate 300, a main blade 310 is vertically installed. On both sides of the main blade 310, there are pressing plates 320 horizontally arranged. At the bottom of the pressing plates 320, there are elastic pads 330, and the bottom surface of the elastic pads 330 is lower than the bottom surface of the cutting edge of the main blade 310. Between the pressing plates 320 and the lifting plate 300, there is an elastic connecting member 340; a limit side baffle device 400 is arranged at the upper part of the frame 100 and in the feeding end direction of the gantry bracket 200, including fixed vertical plates 410 fixed on both sides of the upper end of the frame 100, and limit baffles 420 respectively arranged on the inner sides of the two fixed vertical plates 410 and capable of sliding and adjusting relatively; it also includes a baffle 500 arranged in the discharging end direction of the gantry bracket 200, and this baffle 500 can be adjusted up and down and back and forth.

[0028] The limit side baffle device 400 further includes a guiding slide bar 430 horizontally and fixedly connected between the two fixed vertical plates 410. The limit baffle 420 is slidably connected to the guiding slide bar 430. On the opposite sides of the two fixed vertical plates 410, there are also electric push rods 440 with output shafts connected to the limit baffle 420. Here, the distance between the bottom of the limit baffle 420 and the conveying roller 110 is less than the diameter of the welding rod. Therefore, during the conveying of the welding rod by the conveying roller 110, the limit baffles 420 on both sides can laterally limit the spread welding rods, effectively preventing single or multiple welding rods from linearly deflecting, and thus improving the cutting accuracy of the welding rods.

[0029] A hydraulic cylinder 360 is also provided at the top of the gantry bracket 200, and the output shaft of the hydraulic cylinder 360 is connected to the lifting plate 300. Inside the upper part of the frame 100 and directly below the gantry bracket 200, there is also a cutting table 350. Inside the cutting table 350, there is a secondary blade 351 that is misaligned with the main blade 310. Moreover, the top surface height of the cutting table 350 is lower than the top surface height of the conveying roller 110. It can be understood that the cutting table 350 can support the welding electrodes on both sides of the cutting line. At the same time, the main blade 310 that vertically punches down can form a shearing force with the misaligned secondary blade 351, making the cutting of the welding electrodes smoother and flatter.

[0030] The elastic pad 330 is a silicone rubber airbag pad; a one-way nozzle valve 331 communicating with the silicone rubber airbag pad is also provided at the top of the pressing plate 320. Through the one-way nozzle valve 331, it is convenient to inflate the inner cavity of the elastic pad 330 using a syringe, and the inflation pressure can be adjusted according to specific circumstances. The elastic connecting member 340 includes a plurality of fixed sleeves 341 vertically fixed to the bottom of the lifting plate 300, guide rods 342 that are telescopically matched with the inside and lower end of the fixed sleeves 341 and whose bottom is connected to the upper end of the pressing plate 320, and springs 343 provided inside the fixed sleeves 341 and whose lower part abuts against the inner end of the guide rods 342. In this embodiment, when the lifting plate 300 descends and drives the main blade 310 to cut the welding electrode, the pressing plates 320 on both sides of the main blade 310 will first come into contact and press the welding electrodes on both sides of the cutting line through the elastic pad 330. The elastic pad 330 can tightly press the scattered welding electrodes according to the contour of the welding electrode. At the same time, the gradually descending lifting plate 300 can push the elastic connecting member 340 to elastically press the pressing plate 320, the elastic pad 330, and the welding electrode. Subsequently, the blade punches and shears the welding electrode. During this process, the welding electrode is always in a stable state of being cut, effectively avoiding the situation of the welding electrode bouncing and swinging during the shearing process, improving the shearing accuracy of the welding electrode, and at the same time preventing the cut short welding electrodes from becoming scattered and rolling down, which may cause difficulties in smoothly conveying them backward.

[0031] A top plate 510 is horizontally fixed at the top of the baffle 500. At both ends of the bottom of the top plate 510, cylinders 520 are vertically installed. A sliding seat 530 is fixed to the bottom of the cylinders 520; among them, the sliding seat 530 is horizontally slidably installed on the side of the frame 100. On both sides of the top surface of the frame 100 along its length direction, there are also scale lines corresponding to the sliding of the sliding seat 530. Pointer devices are also provided on both sides of the baffle 500. It can be understood that the sliding seat 530 is also equipped with a locking device. At the same time, the distance between the baffle 500 and the cutting edge of the main blade 310 is the cutting length required for the welding electrode. The front and rear positions of the baffle 500 can be flexibly adjusted according to the cutting length. After each cutting is completed, the cylinder 520 will drive the baffle 500 to lift, so that the welding electrode can be smoothly conveyed backward.

[0032] In summary, for a solder adjustable shearing machine according to this embodiment, during use, when the lifting plate 300 descends and drives the main blade 310 to cut the welding rod, the pressing plates 320 on both sides of the main blade 310 will first come into contact and press the welding rods on both sides of the cutting line through the elastic pads 330. The elastic pads 330 can tightly press the scattered welding rods according to the contour of the welding rod. At the same time, the gradually descending lifting plate 300 can push the elastic connecting piece 340 to elastically press the pressing plates 320, the elastic pads 330 and the welding rods. Subsequently, the blade punches and shears the welding rod. During this process, the welding rod is always in a stable state of being cut, effectively avoiding the situation of the welding rod bouncing and swinging during the shearing process, improving the shearing accuracy of the welding rod, and at the same time preventing the cut short welding rods from being scattered and rolling down.

[0033] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
