Above-mentioned mold carries limit function, but when factory needs to produce various workpieces and uses common large-sized bender When to adjust limiting just cumbersome, need staff that rear is gone to adjust supports block and fixation, return previous work, if desired compared with It will be wasted time and manpower frequently to adjust supports block.

Utility model content

The purpose of this utility model be to provide it is a kind of convenient for adjust supports block bender, make staff before bender just The relative position of supports block can be adjusted, is not spent behind bender.

The above-mentioned technical purpose of the utility model technical scheme is that：

It is a kind of convenient for adjust supports block bender, including rack, positioned at the wallboard of rack both sides, above rack and with The clamping plate and the abutting arrangement positioned at rack rear of wallboard connection, abutting arrangement includes positioning table, sliding is connected to positioning table On abutting component and sliding be connected to two auxiliary rods of positioning table both sides, auxiliary rod top is connected with cable wire, and cable wire abuts In abutting on component, multiple contraction springs are fixedly connected on the positioning table of corresponding auxiliary rod, the contraction spring other end is fixed It is connected on auxiliary rod, the power that contraction spring is moved downward to auxiliary rod, auxiliary rod bottom end is hinged with control-rod, and control-rod passes through Rack sets and is fixedly connected with pedal in the part of control-rod stretching rack, in the both sides wallboard at corresponding control-rod position Between be fixedly connected with lever shaft, lever shaft is rotationally connected in control-rod.

Adjusting abutting arrangement by using said program, before staff needs bender rear, after adjusting It also needs to fix and abuts component, need to only allow abutting component slidably by pedal before bender now, adjusted rear unclamp and stepped on Plate can fix the relative position for abutting component.

Preferably, being installed with side chute on the wallboard of corresponding positioning table, positioning table is slidably connected in side chute, in side Wire lever is threaded on positioning table in sliding slot, wire lever one end is connected with numerical-control motor.

By using said program, when needing to adjust the front and back position for abutting component, staff can be by controlling number The i.e. controllable component that abuts of motor is controlled to be moved forward and backward, it is time saving and energy saving and mobile steady.

Preferably, the structure of control-rod is Telescopic rod structure.

By using said program, since the control-rod segments relative positions before rack are fixed, before abutting arrangement After when moving, control-rod will stretch with the back-and-forth motion of abutting arrangement.

Preferably, abutting component includes the locating piece being slidably connected on positioning table, the abutting slot being fixedly connected on locating piece Be slidably connected at the fitting that abuts in slot, be hinged with butt junction on the fitting.

By using said program, butt junction can rotate at any time, especially big or when not needing to butt junction in steel plate Waiting directly to get on butt junction overturning, without controlling motor again, moreover it is possible to reserve space as big as possible.

Preferably, being rotatably connected to fine tuning leading screw on fitting, fine tuning leading screw, which passes through, to abut slot setting and is finely tuning Leading screw passes through the one end for abutting slot to be connected with drive mechanism, and drive mechanism is connected with hand-operated wheel across rack.

By using said program, staff can control fine tuning leading screw to turn by hand-operated wheel before bender Dynamic, to finely tune the front and back position of butt junction, the relative position for allowing butt junction is more accurate, increases product quality.

Preferably, drive mechanism includes being connected to the first commutator of fine tuning leading screw, the transmission connecting with the first commutator Bar, the second commutator being connect with drive link, the rear telescopic rod being connect with the second commutator, the prismatic being sheathed in rear telescopic rod Bar and the front stretching bar for being set in the prismatic bar other end.

By using said program, since abutting agency will move forward and backward, if so drive mechanism is telescopic, prismatic Bar is realizing that drive mechanism is telescopic while does not influence the rotation of drive mechanism.

Preferably, being installed with main hydraulic cylinder on wallboard, main hydraulic cylinder is connected with drive block, and drive block is fixedly connected on folder On tight plate, accessory plate is installed on the wallboard at corresponding drive block position, if being threaded with dry repair spiral shell on the auxiliary board Bolt, maintenance bolt one end are abutted with drive block.

By using said program, main hydraulic cylinder is for driving clamping plate to move up and down, when needing to overhaul clamping plate or more When changing mobile upper slitter, clamping plate is promoted, screwing on maintenance bolt can prevent clamping plate from causing the accident because of unexpected whereabouts.

Preferably, being installed with workbench before rack, workbench includes being respectively fixedly connected with two on the wallboard of both sides Fixed block, the fromer rail being fixedly connected among two fixed blocks and sliding are connected to the left limit plate on fromer rail.

By using said program, staff's left limit plate in bending steel plate can determine the left and right of steel plate with respect to position It puts, left limit plate is because can slide staff can be by sliding left limit in the steel plate for processing different type demand Position plate determines different relative positions.

Preferably, sliding is connected with right limit plate on fromer rail.

By using said program, left limit plate and the cooperation of right limit plate can form a slot, and staff is by steel plate The left and right relative position of steel plate can not only be determined by being positioned in slot, moreover it is possible to be prevented steel plate from occurring crooked, be influenced product quality.

Preferably, array offers threaded hole on fromer rail, on the left limit plate and right limit plate of corresponding threaded hole It is threaded with fixing bolt.

By using said program, after left limit plate and right limit plate are adjusted to suitable position by staff, due to Left limit plate and right limit plate are it is also possible to slide, so staff needs to tighten fixing bolt, by left limit plate and Right limit plate is fixed.

In conclusion the utility model has the advantages that：

1. abutting arrangement is adjusted before staff needs bender rear, fixed abutting group is also needed to after adjusting Part, need to only be allowed by pedal before bender and abut component slidably now, and abutting group can be fixed by unclamping pedal after having adjusted The relative position of part；

2. when needing to adjust the front and back position for abutting component, staff can be by controlling numerical-control motor is i.e. controllable to support Connected components are moved forward and backward, time saving and energy saving, and mobile steady；

It is especially big or can directly will abutting when do not need to butt junction in steel plate 3. butt junction can rotate at any time Head overturning is got on, without controlling motor again, moreover it is possible to reserve space as big as possible；

4. staff can control fine tuning leading screw rotation by hand-operated wheel before bender, to finely tune butt junction Front and back position, the relative position for allowing butt junction is more accurate, increases product quality.
