Abstract
The utility model discloses a rolling-forming and repairing worktable for an arched mining bracket, which comprises a fixed worktable and a rotary worktable arranged above a tabletop of the fixed worktable, wherein the rotary worktable can horizontally swing; an inlet carrier roller and an outlet carrier roller are arranged on the tabletop of the fixed worktable in a spaced way, and a pair of mould roller wheels driven by a power source are arranged between the inlet carrier roller and the outlet carrier roller; the rotary worktable consists of an upper beam frame and a lower beam frame; an inlet-side roller wheel and an outlet-side roller wheel are respectively arranged at the two sides of the pair of mould roller wheel on the rotary worktable through tracks and track seats in a sliding way; the two track seats are respectively in transmission connection with a feeding motor through screw rod pairs; and a swinging motor which is fixedly arranged on the fixed worktable is screwed with a nut fixed on the rotary worktable through a swinging screw rod. The rolling-forming and repairing worktable has the advantages of solving the problem of retraction caused by the driving of a present hydraulic cylinder, ensuring the consistency between the curvature radius of the arched bracket formed through rolling-bending and the set value and improving the finished product rate and quality of the arched bracket.
Description
Technical field
The utility model relates to arch support, especially relates to mining arch support roll forming repair platform.
Background technology
Arch support is the manufacturing processing of U shaped steel arch support especially, adopts forcing press to finish more.Owing to needs repeatedly the people to expect moulding, and send to by manpower fully, so labour intensity is big, operating personnel are many.Machine is repaired at present commercially available U shaped steel arch support roll forming, utilizes " side roller swing type four rollers roll curved principle ", has solved the deficiency that production efficiency is low, labour intensity is big in above-mentioned brake forming process to arch support.But also having weak point, promptly be arranged on rotary table upper inlet side wheel and outlet side roller, is to adjust, locate by hydraulic-driven, to realize rolling the arch support of bending different curvature radius; But when pressure in the roll bending process arrives the hydraulic cylinder power output limit greatly, rebound phenomenon will appear in the piston rod of hydraulic cylinder, and the radius of curvature of therefore rolling the arch support of bending is the off-design value, cause the arch support quality to descend even scrap; The adjustment of inlet side roller and outlet side roller simultaneously, the necessary shutdown operation in location, operating efficiency is lower.
Summary of the invention
The utility model purpose is to provide the mining arch support roll forming of a kind of stable and reliable operation repair platform.
For achieving the above object, the utility model can be taked following technical proposals:
Mining arch support roll forming repair platform described in the utility model, it comprises stationary work-table and is arranged on the rotary table of its table top upper horizontal swing; On the table top of described stationary work-table, be arranged at intervals with the import and export carrying roller, between described import and export carrying roller, be provided with a pair of mould roller by drive power source; Described rotary table is made of upper and lower roof beam structure; On rotary table, be positioned at described a pair of mould roller both sides and be provided with inlet side roller and outlet side roller by track and railroad shoe slip respectively; Described two railroad shoes are respectively by lead screw pair and feeding motor driving coupling; Be set with the swing motor on stationary work-table, described swing motor is spirally connected by swing leading screw and the nut that is fixed on the rotary table.
Described upper and lower roof beam structure is character.
Described stationary work-table or rotary table are provided with the angle index chi.
The cross section of described track is an oat tail groove structure.
The utility model advantage is to be positioned at described a pair of mould roller both sides and is provided with inlet side roller and outlet side roller by track and railroad shoe slip respectively on described rotary table; and with described two railroad shoes respectively by lead screw pair and feeding motor driving coupling; therefore, the adjustment of inlet side roller and outlet side roller, positioning instant can carry out under not shutdown situation.On stationary work-table, be set with the swing motor, described swing motor is spirally connected by swing leading screw and the nut that is fixed on the rotary table, solved the rebound phenomenon that existing Driven by Hydraulic Cylinder produces, guaranteed that the radius of curvature of rolling the arch support of bending conforms to design load, has improved arch support yield rate and quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, mining arch support roll forming repair platform described in the utility model, it comprises the stationary work-table 1 that is provided with angle index chi 15 and is arranged on the rotary table 2 of its table top upper horizontal swing; On the table top of described stationary work-table 1, be arranged at intervals with import and export carrying roller 3,4, between described import and export carrying roller 3,4, be provided with a pair of mould roller 5,6 by drive power source; Described rotary table 2 is configured to by upper and lower door tee beam; Being positioned at described a pair of mould roller 5,6 both sides on rotary table 2 is that the track of oat tail groove structure and railroad shoe 7,8 are slided and be provided with inlet side roller 9 and outlet side roller 10 by cross section respectively; Described two railroad shoes 7,8 are respectively by lead screw pair and feeding motor 11,12 driving coupling; Be set with swing motor 13 on stationary work-table 1, described swing motor 13 is spirally connected by swing leading screw and the nut 14 that is fixed on the rotary table 2.
