Preferably, be formed with baffle plate,, optimized the convenience and the accuracy of location, copper pipe end by baffle plate in described bend bar semi-circular recesses end.
Preferably, described promotion cylinder and bend bar fixedly install the casing upper surface diagonally, and the diagonal angle setting can effectively reduce the space hold of each apparatus.
Preferably; The groove of bending template offered to diameter progressively become big semi-circular recesses structure; The groove of bending wheel is offered the groove that progressively increases for coupling ground radius; Groove one girth on the described bending wheel is equal to, or greater than bending template upper groove length, and this structure can the bending of simple realization reducing copper pipe.
Bender of the present invention, simple in structure, rationally distributed, can effectively reduce one of operative employee; Reduce staff labor intensity, help promoting product quality simultaneously, can also be applied to the copper pipe bending of reducing simultaneously; But enlarge range of application, improved the machine utilization rate, cut down finished cost.
Description of drawings
Fig. 1 is a bender side view of the present invention;
Fig. 2 is a bending mould structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is elaborated.
As depicted in figs. 1 and 2; The bender of preferred embodiment of the present invention comprises the support case 1 that is fixedly installed on the base; Be fixedly installed on the promotion cylinder 2 of casing upper surface one side; Rotatably be fixed on the bending wheel 3 of cylinder 2 piston arm ends, and the bend bar 4 that can drive its rotation by drive motors.
Wherein, described support case 1 is welded by hard metal sheet material, certainly, adopts tubing to be welded into the purpose that support frame can be realized the present invention equally.Promote cylinder 2 and be arranged on a side that supports case 1 upper surface by bolt, preferably, it is arranged on the angle supporting case 1 and its piston arm points to casing 1 upper surface center.Upper and lower surfaces is set with strap 31 respectively in described piston arm end, rotatably is set with bending wheel 3 in the inboard, end of two straps 31, and its circumferencial direction of upper edge, side of described bending wheel 3 offers semi-circular recesses 32.
Be set with bending mould 4 with promoting cylinder 2 corresponding opposite sides, described bending mould 4 is fixedly installed on the rotating disk 41, and described rotating disk 41 can drive 4 rotations of bending mould then by being fixedly installed on the drive motors driven rotary that supports case 1 inside.Described bending mould 4 is a block structure, and an one of which side is formed with and the smooth curved surface of being scheduled to the bending shape coupling, and curved surface is provided with semi-circular recesses 42.Described semi-circular recesses 42 is identical with the radius of semi-circular recesses 32, can form closed disc when promptly both contact.
For ease of operation; Above described bending mould 4 side relative, also be set with clamp structure with promoting cylinder 2; It comprises that an end is fixedly connected on the L shaped support arm 43 of bending mould 4 upper surfaces; The vertical arm portion of described support arm 43 extends bending mould 4 the place aheads and also offers screwed hole on it; Positioning screw 44 can insert wherein with mating, described positioning screw 44 be provided with that position and semi-circular recesses 42 flush and can through rotation make positioning screw 44 away from or near semi-circular recesses 42.
For improving locating effect to copper pipe, be formed with baffle plate 45 at described semi-circular recesses initiating terminal, described baffle plate 45 flushes with the curved surface of bending mould or the side curved surface that is lower than the bending mould slightly interferes to avoid taking turns with bending.
To describe in the hope of the present invention is further set forth through detailed process below.
After the assembling, the semi-circular recesses of bending wheel and bending mould is positioned on the same horizontal plane, and the distance of bending mould and bending wheel can guarantee in whole bending process, to keep the applying of bending wheel and bending mould to contact within the stroke that promotes cylinder.When needs are managed bending; First-selection need be with icing perhaps sandstone filling in the copper pipe to avoid that flat hole takes place in the bending process; In the groove with copper pipe end embedding bending template its end and baffle plate 45 are held then; And by positioning screw its end is blocked, drive then and promote that cylinder fits bending wheel and bending mould contact and pipe is fixing spacing, and then the driven in rotation dish rotates the rotation of drive bender dish by two coupling semi-circular recesses; In rotation process, promotion cylinder promotion bending wheel is fitted in real time with the curved surface of bending mould and is contacted the predetermined bending that can realize like this copper pipe.After bending is accomplished, drive the promotion cylinder and return, bolt is unscrewed, promptly accomplish a copper pipe bending.
In describing above only is that the same copper pipe of diameter is bent; Bend pipe for reducing can utilize the present invention's device to realize equally; At first the groove of bending template is offered to diameter progressively becomes big semi-circular recesses structure, equally the groove of bending wheel is offered the groove that progressively increases for radius then, it should be noted that; Groove one girth on the described bending wheel promptly is equal to, or greater than bending template upper groove length, to avoid interference.
In when bending, only need the corresponding contact of groove can be realized becoming the bending of diameter copper pipe by the step of previous description by location structure, repeat no more at this.
