Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a beveling machine for sheet metal. Background Technology

[0002] The central trough is a component of the conveyor, and it requires beveling during its processing.

[0003] A flame cutting machine is a common beveling device used to process bevels or grooves (called bevels) at specific angles on the edges of metal sheets. For example, patent announcement number CN202861587U discloses a flame cutting device for beveling and thinning thick plates, including a track, a cutting carriage, a support, a cutting nozzle, and a preheating nozzle. The support includes a column and a horizontal bar. One end of the column is fixed to the cutting carriage, which is slidably mounted on the track. The other end of the column is fixedly connected to the horizontal bar. The horizontal bar has two sets of positioning structures, which are used to fix the cutting nozzle and the preheating nozzle, respectively. The cutting nozzle and the preheating nozzle are respectively connected to a gas storage tank through pipes.

[0004] This device can significantly increase the cutting depth for beveling thick plates, thereby increasing the thinning length and solving the problem of serrated defects on the cut surface. However, the cutting nozzle and preheating nozzle must be located on one side of the cutting carriage. The overall center of gravity of the support, cutting nozzle, and preheating nozzle is off-center from the geometric center of the cutting carriage, making the cutting carriage prone to tipping over during movement and resulting in poor stability. Summary of the Invention

[0005] In view of this, and to address the above-mentioned shortcomings, it is necessary to propose a beveling machine for sheet metal.

[0006] A beveling machine for sheet metal includes a carrier, a cutting nozzle, and a unit track. The carrier includes a body and rear wheels. The cutting nozzle is located on one side of the body, and a rear wheel is located on each side of the body. The unit track includes a track body, and the rear wheels include a first roller and a second roller. The first roller and the second roller are coaxially connected. The diameter of the first roller is smaller than the diameter of the second roller. The rolling surface of the first roller rolls in contact with the top surface of the track body, and the side surface of the second roller contacts the side surface of the track body.

[0007] Preferably, the unit track includes a first protrusion and a second protrusion, which are respectively located at both ends of the track body. One end of the track body has two parallel first protrusions that form a concave groove with the track body. The other end of the track body has a second protrusion whose shape matches the shape of the concave groove.

[0008] Preferably, the track body is provided with a rolling groove.

[0009] Preferably, the carrier vehicle includes front wheels that are in rolling engagement with rolling grooves.

[0010] Preferably, the front wheel is rotatably connected to the vehicle body.

[0011] Preferably, the track body is provided with a through-process hole.

[0012] Preferably, there are at least two rows of through-holes, with adjacent rows of through-holes staggered.

[0013] Preferably, the carrier vehicle includes a heat insulation plate, which is disposed on one side of the vehicle body.

[0014] Preferably, the cutting nozzle can move up, down, left, and right relative to the vehicle body, and the cutting nozzle can rotate relative to the vehicle body.

[0015] Preferably, the beveling machine for sheet metal includes a support frame, which includes a support column, a first crossbar, a second crossbar, a vertical bar, and a third crossbar. The support column is mounted on the vehicle body. One end of the first crossbar is slidably connected to the support column, and the other end of the first crossbar is slidably connected to one end of the second crossbar. The other end of the second crossbar is slidably connected to the upper end of the vertical bar, and the lower end of the vertical bar is rotatably connected to one end of the third crossbar. The other end of the third crossbar is connected to the cutting nozzle.

[0016] Beneficial effects: The combination of different diameters of the first and second rollers in the rear wheel design can lower the center of gravity of the vehicle and improve its stability; the distance between the two first rollers and the main body of the track can be maximized, which can reduce the torque formed by the weight of the cutter and increase the torque formed by the weight of the vehicle, thus improving the stability of the vehicle; the gripping force formed by the second roller and the main body of the track further generates resistance to the vehicle's rollover, improving the stability of the vehicle.

Detailed Implementation

[0029] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0030] See Figures 1 to 4 This utility model provides a beveling machine for sheet metal, including a carrier 20, a cutting nozzle 30, and a unit track 10. The carrier 20 includes a body 21 and rear wheels 22. The cutting nozzle 30 is located on one side of the body 21, and a rear wheel 22 is located on each side of the body 21. The unit track 10 includes a track body 11. The rear wheels 22 include a first roller 221 and a second roller 222. The first roller 221 and the second roller 222 are coaxially connected. The diameter of the first roller 221 is smaller than the diameter of the second roller 222. The rolling surface of the first roller 221 rolls in contact with the top surface of the track body 11, and the side surface of the second roller 222 contacts the side surface of the track body 11.

[0031] For example, the first roller 221 and the second roller 222 are designed separately. The vehicle body 21 is provided with a rotating shaft 223. The first roller 221 and the second roller 222 are coaxially mounted on the rotating shaft 223 and fixed by a nut 224. A spring washer 225 is provided between the second roller 222 and the nut 224. The second roller 222 can move slightly along the axis of the rotating shaft 223 when subjected to force.

[0032] The upper end of the nozzle 30 is connected to a combustible gas pipeline, and the lower end of the nozzle 30 sprays a combustion flame. The nozzle 30 has a conventional structure and will not be described in detail below.

[0033] With the rear wheel 22 on the same side as the cutting nozzle 30 as the center of rotation, the torque generated by the weight of the cutting nozzle 30 is greater than the torque generated by the weight of the vehicle body 21, and the vehicle body 21 will roll over.

[0034] Beneficial effects: The design of the rear wheel 22 with different diameters of the first roller 221 and the second roller 222 can lower the center of gravity of the vehicle body 21 and improve the stability of the vehicle body 21; the distance between the two first rollers 221 and the main body of the track can be maximized, which can reduce the torque formed by the weight of the cutter 30, while increasing the torque formed by the weight of the vehicle body 21, thus improving the stability of the vehicle body 21; the gripping force formed by the second roller 222 and the main body of the track further forms the resistance to the side rollover of the vehicle body 21, thus improving the stability of the vehicle body 21.

[0035] See Figure 5 Furthermore, the unit track includes a first protrusion 12 and a second protrusion 13. The first protrusion 12 and the second protrusion 13 are respectively located at both ends of the track body 11. One end of the track body 11 is provided with two parallel first protrusions 12, which form a concave groove with the track body 11. The other end of the track body 11 is provided with a second protrusion 13, the shape of which matches the shape of the concave groove.

[0036] Multiple unit tracks 10 are connected end to end in sequence. The second protrusion 13 of the next unit track 10 is inserted into the concave groove of the previous unit track 10 to realize the splicing of several unit tracks 10.

[0037] See Figure 7 Furthermore, a first through hole 14 is provided at the root of the inner sidewall of the first protrusion 12, and the axis of the first through hole 14 is the intersection line of the end face of the track body 11 and the inner sidewall of the first protrusion 12. A second through hole 15 is provided at the root of the outer sidewall of the second protrusion 13, and the axis of the second through hole 15 is the intersection line of the end face of the track body 11 and the outer sidewall of the second protrusion 13.

[0038] The first protrusion 12 and the second protrusion 13 are processed in one step: First, prepare a flat, elongated steel plate and draw circles corresponding to the two first through holes 14 and the two second through holes 15 on the steel plate; second, starting from the center of one of the second through holes 15, cut through the steel plate along its width towards one side wall, and starting from the center of the other second through hole 15, cut through the steel plate along its width towards the other side wall; third, starting from the center of one second through hole 15 and ending at the center of one first through hole 14, make a straight cut, starting from the center of the other second through hole 15 and ending at the center of the other first through hole 14; finally, starting from the center of one first through hole 14 and ending at the center of the other first through hole 14, make a straight cut. Due to the possibility of overcutting, the following will occur: Figure 6 The crack M shown is cut to create two first through holes 14 and two second through holes 15 with a diameter larger than that of the crack M, thereby reducing the scrap rate of the unit track 10.

[0043] See Figure 5 Furthermore, there are at least two rows of through process holes 16, with adjacent rows of through process holes 16 staggered. The through process holes 16 not only reduce weight but also reduce the amount of thermal deformation of the track body 11.

[0044] For example, the rolling groove 17 extends along the length of the track body 11, and a rolling groove 17 is provided on each side of the track body 11, with a through process hole 16 located between the two rolling grooves 17.

[0045] See Figures 1 to 4 Furthermore, the carrier vehicle 20 includes a heat insulation plate 24, which is located on one side of the vehicle body 21. The heat insulation plate 24 can also lower the center of gravity of the vehicle body 21 and increase the stability of the vehicle body 21.

The adjusting element 47 includes a slide 471, a worm 472, a first gear 473, a first bevel gear 474, a second bevel gear 475, a second gear 476, and a rack 477. The worm 472 is rotatably connected to the slide 471. The worm 472 meshes with the first gear 473. The first gear 473 is coaxially connected with the first bevel gear 474. The first gear 473 and the first bevel gear 474 rotate synchronously. The first bevel gear 474 meshes with the second bevel gear 475. The second bevel gear 475 and the second gear 476 are coaxially connected. The second bevel gear 475 and the second gear 476 rotate synchronously. The second gear 476 meshes with the rack 477.
