The key points of the technical scheme adopted by the utility model for the implementation of the pipe bending machine are as follows: the pipe bending machine comprises a frame and a bending mold plate, wherein a bedplate is arranged in the middle of the frame and is opposite to an upper mode plate on the piston rod of a cylinder above the bedplate; plate holes on the left and the right sides of the upper die plate are in running fit with the end shafts of a left second rolling bar and the end shafts of a right second rolling bar; vertical cylinders are arranged on the bottom plate of the frame on the left and the right sides of the bedplate; the front end shafts and the rear end shafts of first rolling bars are in running fit with holes in the middle of a front swing plate and in the middle of a rear swing plate; connecting rods at the lower ends of the front and the rear swing plates are hinged with the piston rods of the vertical cylinders; and holes at the upper ends of the front and the rear swing plates are in running fit with the end shafts of the second rolling bars.

Description

A kind of bending machine

Technical field:

The utility model relates to a kind of cutting-free machining equipment, particularly a kind of bending machine.

Background technology:

There is a kind of shape of refrigeration piping of refrigeration product comparatively complicated now, its structure is, refrigerator pipes is a plurality of parallel U type pipes, and this pipe forms the Ω grooved in the foot of each U type pipe end, when adopting numerical controlled bending of pipe equipment, the equipment manufacturing cost height, and with common angle pipe equipment, bend pipe efficient is low, quality is unstable.

Summary of the invention:

The purpose of this utility model provides the bending machine that a kind of equipment investment is few, bending quality good and production efficiency is high.The utility model realizes that the technical scheme main points of utility model are, a kind of bending machine, comprise frame and bending template, it is characterized in that: it is relative with the cope match-plate pattern that is supported on the cylinder piston rod on the support of its top that the centre of frame is provided with a platen, before the cope match-plate pattern left and right sides, the overhanging plate hole at back two ends respectively with a left side, the end axle of right second rolling bar changes cooperation, the radius of this second rolling bar is identical with the radius of the Ω type groove for the treatment of bend pipe, left side at described platen, respectively be provided with an identical vertical cylinder on the framework soleplate of right both sides, the described first rolling bar front and back end the axle with before, back pendulum plate supermedial hole commentaries on classics is joined, before this, the connecting rod and the described vertical cylinder piston rod of pendulum plate lower end, back are hinged, before this, the hole of pendulum plate upper end, back and the two end axles commentaries on classics of second rolling bar are joined, gap between described first rolling bar and the second rolling bar outer rim is identical with caliber to be curved, left side at framework soleplate, it is relative with described platen that a location-plate is respectively established at right two ends, and location-plate is provided with movably baffle plate.The utility model has the high remarkable advantage of small investment, good product quality and efficient compared with the prior art.

Description of drawings:

Fig. 1 is the refrigerator pipes front view that the utility model need bend, and Fig. 2 is the right side view of Fig. 1, and Fig. 3 is a plurality of U type tubular construction schematic diagrames that parallel, and Fig. 4 is the bend pipe schematic diagram of the utility model bending machine, and Fig. 5 is the structural representation of the utility model bending machine.

The specific embodiment:

The utility model is described in further detail in conjunction with following embodiment, with conventional angle pipe equipment long tube is bent into a plurality of U type pipes that are parallel to each other.Bending machine of the present utility model is to curving the pipe (referring to Fig. 3) of a plurality of U type pipes, being bent into needed shape (seeing Fig. 1, Fig. 2).Above base plate 1 middle part of frame, be provided with platen 7, it is relative with described platen that location-plate 3 is respectively established at the two ends of base plate 1, being provided with on this location-plate can be left, the baffle plate 11 that moves right, on described platen, be fixed with support 8, cylinder 9 is located on this support, cope match-plate pattern 10 piston rod of cylinder therewith connects and is relative with platen, the rear and front end of two second rolling bars 6 rotational support is respectively held in the overhanging hole about described cope match-plate pattern, the diameter of this rolling bar is by being determined by the diameter of bend pipe Ω groove, each fixes a vertical cylinder 2 on the framework soleplate of the described cope match-plate pattern left and right sides, the connecting rod of the piston rod end of this vertical cylinder and pendulum plate 4 lower ends, front and back is hinged, the upper end of this pendulum plate and the two end axles of described second rolling bar are hinged, the axle at the two ends of first rolling bar 5 changes cooperation, in the hole at two pendulum plate middle parts, described front and back, the gap between the outer rim of described first rolling bar and second rolling bar is by the diameter of bend pipe.

The operation principle and the method for operating of the utility model bending machine be, the cylinder of platen top is risen, and U type pipe to be curved is placed on the platen, makes the two ends for the treatment of bend pipe and the center symmetry of platen, and its method is to regulate with the plate on the location-plate; Cylinder 9 actions, being about to U type pipe to be curved under the cope match-plate pattern is pressed on the platen, but can not make the pipe compressive strain, simultaneously, second rolling bar is bent downwardly pipe to be curved with after first rolling bar contacts, the piston rod of the left and right vertical cylinder on the framework soleplate is risen, drive left and right two pendulum plates respectively around the rotation that makes progress of left and right two first rolling bars, make treat bend pipe be bent to Ω after two cylinders stop, the stroke of above-mentioned first cylinder and vertical cylinder is according to being determined by the requirement of pipe, after being bent into, above-mentioned three cylinders are resetted after, can take out the pipe that bends.This bending machine only need be placed and the taking-up pipe fitting with artificial, and all the other work are all finished by bending machine, and production efficiency height, steady quality and the simple cost of this equipment are low, easy to operate.
