I.e. the utility model additionally provides a kind of belt bar, wire rod, tubing grinding-polishing production line, the belt stick Material, wire rod, tubing grinding-polishing production line contain more above-mentioned belt bars, wire rod, tubing grinding-polishing process equipment, more Belt bar, wire rod described in platform, tubing grinding-polishing process equipment are alternatively arranged, it can be understood as contain three Fig. 1 at this time It the equipment and is arranged successively from left to right, the institute of belt bar, wire rod described in every, tubing grinding-polishing process equipment It states feeding center line to be overlapped, belt bar, wire rod described in every, the feeding direction of feed of tubing grinding-polishing process equipment are equal It is identical.Wherein, when which is the belt bar, wire rod, tubing grinding-polishing process equipment normal work, The direction of advance of material 33, such as the feeding feeding of the belt bar, wire rod, tubing grinding-polishing process equipment in the utility model Direction is the direction in Fig. 1 from left to right.

The course of work of above-mentioned belt bar, wire rod, tubing grinding-polishing process equipment is described below.

It first has to (pass through rotation for the height of material (by taking bar as an example) the adjustment bottom pinch roll 3 of different batches specification Adjustment bolt 4 with left-right rotary screw thread, so that the lifting of bottom pinch roll 4 or decline) so that bar enters clamping and conveying device quilt After up-down rollers clamp, the feeding center line L1 that the center line of material 33 is just being better than equipment is overlapped.

Front rollgang of the bar to be processed Jing Guo this equipment (is passed after bar head enters clamping and conveying device by monitoring Sensor issues signal), the piston rod of pressure clamping cylinder 8 is released, and pushes top pinch roll 5 to move down, thus with bottom pinch roll 3 Bar is clamped together, is pitched arrangement arrangement since upper bottom pinch roll strikes a bargain, under the driving of lower roll hydraulic motor, is realized the rotation of bar Turn to advance.

After pinch roller (top pinch roll 5 and bottom pinch roll 3) is left in bar tail portion, (signal is issued by monitoring sensor), The piston rod for depressing clamping cylinder 8 retracts, and top pinch roll 5 is driven to rise.

Work as failure, when being unable to normal process production, hydraulic motor can be rotated backward, and bar can be reversely rotated and be moved back It is dynamic to exit.

When enclosed grinding belt 18 is replaced, replaced from the side of roller；The cylinder rod of tensioning cylinder 19 retracts, Abrasive band is in relaxed state, and after removing old sand band replacement fresh sand band, cylinder rod is released, to be tensioned abrasive band.

Start driving motor 22, if 18 sideslip of grinding belt, tensioning cylinder 19 retracts cylinder rod, so that abrasive band relaxation, The connection fastening bolt between driven shaft 24 and driven shaft pedestal 25 is unclamped, according to sideslip direction, the deflection of appropriate adjustment driven shaft Direction and angle, then fastening bolt, restarts motor, such as goes back sideslip, continue to adjust again, until abrasive band rotates Afterwards, stablize not sideslip.

Bistrique rack 9 is stretched out in the cylinder rod for being in raised configuration namely grinding head lifting cylinder 10 when expecting；When bar Head enters behind the region where grinding belt 18 (automatic detection), and the cylinder rod of grinding head lifting cylinder 10 retracts, bistrique rack 9 It falls, the grinding belt 18 of tensioning is pressed on bar, and the bar of continuous rotation feeding is acted in high-speed rotating grinding belt 18 Under, realize grinding.

According to different diameter specifications, the bar of unlike material, adjustment can be reached by rotating grinding head rising-falling tone the whole series 11 Different grinding amounts is realized in the adjustment of 9 drafts of bistrique rack, so that grinding loads substantially uniform stabilization.In addition, according to The requirement of different surfaces finish and removal amount, can select varigrained grinding belt 18 model carry out using.

It in order to facilitate understanding and describes, absolute positional relation is used in the utility model and is stated, orientation therein Word "upper" indicates the upper side direction in Fig. 1, and "lower" indicates that the downside direction in Fig. 1, " left side " indicate the left direction in Fig. 1, " right side " indicates the right direction in Fig. 1, it can be understood as the utility model has used the observation for reading the reader of the utility model Visual angle.But the above-mentioned noun of locality cannot understand or be not construed as the restriction to scope of protection of the utility model.

The above, only specific embodiment of the utility model cannot limit the range that utility model is implemented, institute with it With the displacement of its equivalent assemblies, or according to equivalent variations made by the utility model patent protection scope and modification, should all still fall within The scope that this patent is covered.In addition, between technical characteristic and technical characteristic in the utility model, technical characteristic and technical solution Between, between technical solution and technical solution use can be freely combined.
