Description
Technical field
[0001] the utility model relates to the precise forging machine technical field, is adjustable height precise forging machine workpiece support device.
Background technology
Precise forging machine is when forging elongated material, for the forging material after preventing from heating because action of gravitation occurs bending and deformation, impact forges quality, all can forge material supporting near the swaging place with the work mounting s that plays the aiding support effect, to reduce or to eliminate the flexural deformation that forging is expected.But, the supporting arm of present work mounting s is under the driving of hydraulic cylinder, the rise of supporting arm is highly non-adjustable, simultaneously, cylinder pressure can not stepless voltage regulation, so, when forging elongated material, cylinder pressure is delivered on elongated material by supporting arm, makes elongated material produce flexural deformation, has a strong impact on product quality.It is adjustable that this patent rises height design with supporting arm, preferably resolves this technical barrier.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable height precise forging machine workpiece support device, has realized that the height of precise forging machine workpiece support is adjustable, makes precise forging machine when forging, and avoids forging material deformation.
The technical solution of the utility model is adjustable height precise forging machine workpiece support device, it is to be realized the height of work mounting s is regulated by the PLC controller, it is characterized in that: which comprises at least support roller, work mounting s, sector gear, gear, encoder, hydraulic cylinder, servo valve and PLC controller; Workpiece support is to be made of two arms that are fixedly connected with, and the angle between two arms is constant, and the end of one arm is fixedly installed support roller, and the end of another one arm is fixedly connected with the lever end of hydraulic cylinder, and the oil inlet end of hydraulic cylinder is provided with servo valve; Workpiece support is also fixing with the sector gear interlock, and sector gear and gear engagement are provided with encoder in the rotating shaft of gear; Encoder and servo valve and the conducting of PLC controller.
Described work mounting s comprises two arms, and one arm is straight-arm, and its front end is fixedly connected with the lever end of hydraulic cylinder; Another one arm is L-shaped, and its front end and support roller are fixed, and flex point place and sector gear interlock are fixing.
Described support roller supports forges material.
The inner editor of described PLC controller has the functional relation of support roller height and gear corner.

Characteristics of the present utility model are closed-loop controls of having adopted the PLC controller, by the corner of encoder measuring workpieces supporting, to obtain control signal, control the stroke of hydraulic cylinder by controlling servo valve, thereby obtain adjustable work mounting s height; The rise of work mounting s simultaneously highly can be adjusted according to the diameter of forging material, has avoided traditional work mounting s to forging the flecition of material, has improved product quality.
Description of drawings
Below in conjunction with embodiment, the utility model is further described.
Fig. 1 is the structural representation of adjustable height precise forging machine workpiece support device.
In figure: 1, forge material; 2, support roller; 3, work mounting s; 4, sector gear; 5, gear; 6, encoder; 7, hydraulic cylinder; 8, servo valve; 9, PLC controller.
The specific embodiment
As shown in Figure 1, adjustable height precise forging machine workpiece support device is to be realized the height of work mounting s 3 is regulated by PLC controller 9.
The structure of work mounting s 3 is to become fixed angle by two arms, is fixed together.One arm is L-shaped, and one arm is straight-arm.
The front end of L shaped arm and support roller 2 are fixing, and support roller 2 supports forges material 1, and namely the height of forging material 1 is determined by the bearing height of support roller 2.
The flex point place of L shaped arm and sector gear 4 interlocks are fixing, i.e. the rotation of L shaped arm can drive the rotation of sector gear 4.
The front end of straight-arm is fixedly connected with the cylinder rod end of hydraulic cylinder 7, and hydraulic cylinder 7 can promote the straight-arm motion, thereby drives the mass motion of work mounting s 3.
The oil inlet end of hydraulic cylinder 7 is provided with servo valve 8, and servo valve 8 is controlled the cylinder bar motion of hydraulic cylinder 7.
Sector gear 4 and gear 5 engagement interlocks have encoder 6 in the rotating shaft of gear 5, encoder 6 adopts photoelectric encoder, can read and transmit the corner of gear 5.
The functional relation of support roller 2 height and gear 5 corners is the brachiums by work mounting s 3, and the tooth of sector gear 4 and gear 5 is than determining, different according to the parameter of each parts, functional relation is different.
During work, support roller 2 holds up forges material 1, encoder 6 reads the corner of gear 5, and output is sent to PLC controller 9, and PLC controller 9 is through calculating, draw the height that needs of support roller 2, and exporting signal to servo valve 8, servo valve 8 is controlled the oil inlet quantity of hydraulic cylinder 7, thereby promotes lever motion, drive work mounting s 3 motions, thereby with the height of support roller 2 elevate a turnable ladders to needs.
The parts that the present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
