Abstract
A simple arc shaper for steel casing comprises a setting-out board 1 with an arc side, and the radian of the arc side is the same as that of a section of the inner circle of a needed steel casing. The arc side of the setting-out board 1 is one sixth as long as that of the circumference of the needed steel casing. The simple arc shaper for steel casing is characterized by simple structure, easy manufacture, less adjustment times for wrapping steel casing, short operating time, high wrapping speed, labor- and time-saving property, high one-shot molding rate and high quality.
Description
Technical field
The utility model relates to the pick-up unit that a kind of steel casing rolls radian.
Background technology
The steel casing is a material commonly used in the construction foundation working, generally is to be rolled on plate bending rolls by steel plate to form.When rolling,, roll radian and have restive problem because the size of steel casing is bigger usually.Rolling needs repeatedly to adjust the plate bending rolls parameter often, could guarantee that circularity is accurate, not only consumes the worker, and time-consuming, and steel casing one-shot forming rate is low, and shaping speed is slow, and product quality is difficult for guaranteeing.
The utility model content
In order to overcome the defective of existing forming technique, the utility model provides a kind of steel casing simple and easy arc calibrator, solve steel protect roll when rolling that radian is difficult to hold, the one-shot forming rate is low, shaping speed is slow, steel casing product quality is difficult for the technical matters that guarantees.
The technical scheme that its technical matters that solves the utility model adopts is:
The simple and easy arc calibrator of this steel casing is characterized in that: it comprises a stereotype plate with one section arc limit, and the radian on this arc limit is identical with one section radian that plan rolls into shaped steel casing inner periphery.
The arc length of described stereotype plate can be the steel casing and rolls 1/5～1/8 of back circumference.
The optimum length of described stereotype plate can be the steel casing and rolls 1/6 of back circumference.
Described stereotype plate can be sheet metal or non-metal board.
Described stereotype plate preferably adopts steel plate.
The beneficial effects of the utility model are as follows:
The utility model and plate bending rolls are used, and can reduce the difficulty of steel casing radian control, can in time control the inner periphery radian of steel casing when the steel casing rolls, and the radian that rolls of steel casing is detected in real time, and adjust the plate bending rolls parameter according to this.The utlity model has characteristics simple in structure, easy to make, with low cost, can reduce the steel casing and roll the adjustment number of times, reduce the activity duration, accelerate the speed that rolls, the saving of labor, save time, improve steel casing one-shot forming rate, guarantee steel casing product manufacturing quality.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the synoptic diagram of the utility model user mode.
Fig. 3 is the synoptic diagram after the moulding of steel casing.
Reference numeral: 1-stereotype plate, 2-arc limit, 3-steel plate, 4-steel casing, 5-plate bending rolls roller.
Embodiment
Embodiment is referring to shown in Figure 1, and the simple and easy arc calibrator of this steel casing comprises a stereotype plate 1 with one section arc limit, and the radian on this arc limit 2 is identical with one section radian that plan rolls into shaped steel casing inner periphery.The material of described stereotype plate should adopt not yielding, nonabradable material such as steel plate, glass epoxy, plastic plate, and arc length can suitably be adjusted according to product size, generally gets 1/6 circumference of steel casing.
The thickness of stereotype plate 1 is not limit, but Bao Kehou.
Stereotype plate can be sheet metal or non-metal board.The most frequently used is steel plate, can keep the arc limit indeformable.
The course of work of the present utility model is referring to Fig. 2, shown in Figure 3:
When the steel casing rolled, steel plate 3 through constantly rolling, bent to tubular under the clamping of plate bending rolls roller 5, according to steel casing design inner arc, stereotype plate 1 was fitted in the inwall of intending rolling the steel casing, detected the radian that rolls of steel casing 4.Need shut down during detection, in order to avoid machinery is hurted sb.'s feelings.Adjust the plate bending rolls parameter according to this, reduce the steel casing and roll the adjustment number of times.
In application, all right fixedly connected handle of stereotype plate 1 coboundary or lateral edges is with convenient hand-held.
