Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding equipment, and more particularly to a straight seam welding device for a filter. Background Art
[0002] The straight seam welding machine is a high-quality, efficient, and deformation-free welding equipment. It is suitable for the coiling welding of various metals such as stainless steel and carbon steel. The round tubes on the filter often need to be welded with a straight seam welding machine. Specifically, the stainless steel plate is generally preliminarily coiled and welded, and then the preliminarily welded round tube is placed on the straight seam welding machine for further welding. During the preliminary welding, the gap between adjacent welding points is relatively large, resulting in a slight bulge at the weld. The existing straight seam welding machine lacks the seam pressing function, which makes the weld of the final formed round tube uneven, so it is necessary to upgrade and improve the structure. Utility Model Content
[0003] The purpose of the present utility model is to solve the above technical problems and provide a straight seam welding device for a filter.
[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:
[0005] A straight seam welding device for a filter comprises a frame, a support shaft fixedly connected to the side wall of the frame, a strip seat fixedly connected to the top of the frame, the strip seat being hollow inside, an oil cylinder provided above the strip seat, a support plate fixedly connected to the piston end of the oil cylinder, and a seam pressing device and a welding head provided at the bottom of the support plate;
[0006] The seam pressing device comprises a mounting plate and a seam pressing wheel, wherein the mounting plate is welded to the support plate, and the seam pressing wheel is installed between the two mounting plates. Both sides of the support plate are slidably connected to the inner wall of the strip seat.
[0007] The number of the seam pressing devices is two and they are arranged in parallel, one in front and one behind, with the welding head provided between the two seam pressing devices. Normally, one seam pressing device is sufficient for seam pressing, but if the plate thickness is thick, then two seam pressing devices can achieve a better seam pressing effect.
[0008] The left and right sides of the oil cylinder are fixedly connected to L-shaped plates. The left L-shaped plate is penetrated by a limit rod, and the two ends of the limit rod are fixed to the bar seat. The right L-shaped plate is connected to a screw rod, one end of which is axially connected to the bar seat, and the other end of the screw rod passes through the bar seat and is connected to the output shaft of the reduction motor. The reduction motor is mounted on the frame, and the reduction motor drives the screw rod to rotate, thereby driving the oil cylinder to move.
[0009] The front and rear sides of the oil cylinder are both provided with sliding rods, and pulleys are installed at both ends of the sliding rods. The pulleys are in sliding contact with the side walls of the bar seat, and the sliding rods are in support contact with the bar seat. By arranging the sliding rods to bear part of the weight of the oil cylinder, the entire weight is prevented from being pressed on the screw rod and the limit rod.
[0010] A hook assembly is provided on the side wall of the strip seat. The hook assembly comprises a fixed plate, a rotating shaft, a rotating seat, and a handle. The fixed plate is fixedly connected to the strip seat, the rotating shaft is fixed to the fixed plate, the rotating seat is movably sleeved on the rotating shaft, and the handle is mounted on the bottom of the rotating seat. The hook assembly is used to hold the support shaft to prevent the support shaft from bending when the seam pressing device presses the round tube.
[0011] A pressure strip is embedded on the top of the support shaft. The width of the pressure strip is consistent with the width of the pressure wheel. The pressure strip is parallel to the axis of the support shaft. The pressure strip and the pressure wheel work together to make the weld more flat after pressure.
[0012] Working principle: insert the workpiece into the support shaft and align the straight seam with the pressure strip, turn the handle to hold the support shaft with the rotating seat, start the oil cylinder, the oil cylinder drives the pressure wheel to move down, so that the pressure wheel presses the straight seam, and the reduction motor drives the oil cylinder to move, so that welding can be achieved while pressing the seam. After welding, if the weld is not flat enough, you can press the seam again to make it flat.
[0013] The beneficial effects of the utility model are as follows:
[0014] The utility model realizes the function of pressing the seam by arranging the seam pressing device, thereby avoiding bulges at the weld seam of the round tube; the hook component is used for dragging the support shaft, thereby preventing the support shaft from being bent when the seam pressing device presses the round tube.
