A kind of sheet material belt edge sander
Technical field
The present invention relates to a kind of sheet machining apparatus, particularly relate to a kind of sheet material belt edge sander.
Background technology
The process of plate surface, as surface frosted, equating, polishing, deburring, repairing cut, sheet material side polishes, and always be to have come by hand, inefficiency, crudy is poor.Polish for sheet material side, someone designs automatic belt edge sander, but this machine carries out edging by the abrasive band that is wrapped between motor wheel and abrasive belt wheel, abrasive band must be in tensioning state just good sand limit effect, because abrasive band belongs to the spare and accessory parts of Fast Wearing, the abrasive band dismounting of tensioning state bothers very much, causes the reduction of production efficiency.Meanwhile, during to sheet material sand limit, because sheet metal thickness only has the part of abrasive band width, the utilization rate of abrasive band remainder is not high yet, and the abrasive band frequently changed also is underused, and causes the waste of parts, improves production cost.
Summary of the invention
Object of the present invention is just to provide one to change the outfit conveniently to solve the problem, the sheet material belt edge sander that utilization rate is high.
The present invention is achieved through the following technical solutions above-mentioned purpose.
A kind of sheet material belt edge sander, comprise frame, drive disk assembly, sand edge part, described drive disk assembly and sand edge part are fixedly installed in frame.Described drive disk assembly comprises the live-roller being installed on central rack and the driving motor be installed on bottom frame, and described live-roller is connected with driving motor, is connected between live-roller by tooth bar, described sand edge part is installed on the both sides of live-roller, comprise support, sand limit motor, cylinder, sand cincture, slide rail, slide block, bearing, connecting rod, described sand limit motor is installed on support, described sand cincture is installed on sand limit motor and stretches out on the motor shaft of cradle top surface, sand cincture and live-roller are in same working depth, described cylinder is installed in frame, the piston rod of cylinder is connected with the support of side, described slide rail is installed in frame, described support is connected on slide rail by the slide block set being arranged on its back side, described connecting rod two ends are rack-mount, the middle part of connecting rod is connected with the bearing hinge connection being fixedly mounted on central rack.
As further technical scheme of the present invention, described sand cincture comprises rubber wheel and is socketed on its outer endless abrasive belt, described rubber wheel is fixedly mounted on the motor of sand limit, axis along rubber wheel has multiple U-lag, this U-lag along the circumferential direction arranges, and extension line and the axial line of U-lag are non-intersect.
As further technical scheme of the present invention, described drive disk assembly also comprises and is close to wheel, described being close to takes turns the roller that comprises the fixed bar be fixed in frame, be fixedly connected on the bearing bracket stand on fixed bar and be arranged on bearing bracket stand, described in be close to the both sides that wheel arrangement is arranged on live-roller.
As further technical scheme of the present invention, the diameter 2-10mm larger than rubber wheel of described endless abrasive belt.
When the present invention works, sheet material is transmitted in belt edge sander by live-roller, in transmission process, sand limit driven by motor sand cincture carries out frosted process to sheet material both sides, and cylinder drives the moving up and down of support, thus drives moving up and down of sand limit motor and sand cincture, therefore, most of working face in abrasive band can both participate in work, and abrasive band is fully utilized, and service life extends greatly.In the present invention, rubber wheel have employed the design that circumference has multiple U-lag, and its effect is, when sand limit motor rotation, the centrifugal force produced in rubber wheel rotary course, makes the outer circumference of rubber wheel slightly open, just tightly can prop up abrasive band after opening, and drive abrasive band to rotate together.And abrasive band have employed the diameter larger than the rubber wheel under stopped status, install and all only need directly put or take off with replacing, a bit leicht fallen D/A, change rapidly, and the rubber wheel of duty is fully adjacent to abrasive band, drive it normally work and can not skid.Substantially increase operating efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further explained.
As depicted in figs. 1 and 2, a kind of sheet material belt edge sander, comprises frame 1, drive disk assembly 2, sand edge part 3, and described drive disk assembly 2 is fixedly installed in frame 1 with sand edge part 3.Described drive disk assembly 2 comprises the live-roller 21 be installed in the middle part of frame 1 and the driving motor 22 be installed on bottom frame 1, and described live-roller 21 is connected with driving motor 22, is connected between live-roller 21 by tooth bar, described sand edge part 3 is installed on the both sides of live-roller 21, comprise support 31, sand limit motor 32, cylinder 33, sand cincture 34, slide rail 35, slide block 36, bearing 37, connecting rod 38, described sand limit motor 32 is installed on support 31, described sand cincture 34 is installed on sand limit motor 32 and stretches out on the motor shaft of support 31 end face, sand cincture 34 and live-roller 21 are in same working depth, described cylinder 33 is installed in frame 1, the piston rod of cylinder 33 is connected with the support 31 of side, described slide rail 35 is installed in frame 1, described support 31 is socketed on slide rail 35 by the slide block 36 being arranged on its back side, described connecting rod 38 two ends are arranged on support 31, middle part and the bearing 37 be fixedly mounted in the middle part of frame 1 of connecting rod 38 are articulated and connected.
As shown in Figure 3, described sand cincture 34 comprises rubber wheel 341 and is socketed on its outer endless abrasive belt 342, and described rubber wheel 341 is fixedly mounted on sand limit motor 32, and the axis along rubber wheel 341 has multiple U-lag, this U-lag along the circumferential direction arranges, and extension line and the axial line of U-lag are non-intersect.Diameter 2-the 10mm larger than rubber wheel 341 of described endless abrasive belt 342.
As shown in Figure 4, described drive disk assembly 2 also comprises and is close to wheel 23, the described roller 233 being close to wheel 23 and comprising the fixed bar 231 be fixed in frame 1, be fixedly connected on the bearing bracket stand 232 on fixed bar 231 and be arranged on bearing bracket stand 232, described in be close to wheel 23 arrangement and be arranged on the both sides of live-roller 21.
When the present invention works, sheet material 4 to be processed is transmitted in belt edge sander by live-roller 21, in transmission process, sand limit motor 32 drives sand cincture 34 pairs of sheet material both sides to carry out frosted process, and cylinder 33 drives moving up and down of support 31, thus drives moving up and down of sand limit motor 32 and sand cincture 34, therefore, most of working face in abrasive band 342 can both participate in work, and abrasive band 342 is fully utilized, and service life extends greatly.In the present invention, rubber wheel 341 have employed the design that circumference has multiple U-lag, its effect is, when sand limit motor 32 operates, the centrifugal force produced in rubber wheel 341 rotary course, the outer circumference of rubber wheel 341 is opened slightly, after opening, just can tightly prop up abrasive band 342, and drive abrasive band 342 to rotate together.And abrasive band 342 have employed the diameter larger than the rubber wheel 341 under stopped status; install and all only need directly put or take off with replacing, a bit leicht fallen D/A, change rapidly; and the rubber wheel 341 of duty is fully adjacent to abrasive band 342, it is driven normally to work and can not skid.Substantially increase operating efficiency.
