Abstract
The utility model relates to a calan clamping device which is characterized in that the utility model comprises a hold-down bolt, a beam, a column nut, a hook, a groove face press block and a calan ear; a clamping head of the hold-down bolt is columniform and is opened with two criss-cross circular holes. The match between the hold-down bolt and the beam of the utility model is trapezoidal thread and the matching length is lengthened to ensure that the force-bearing intensity of the calan is enhanced; the criss-cross holes are used on the top of the bolt, which not only is convenient for workers to rotate along all the directions but also increases the manual clamp force; the column nut with trapezoidal threads can be welded again after being scraped; the length of the hook can be adjusted at will according to different workpieces. The set of calan prolongs service life, and an integral type is changed into a split type, thus improving interchangeability and saving production cost.
Description
Technical field
The utility model relates to the clamping device that hydraulic generator box coil press-moulding die adopts, particularly the blue clamping device of card.
Background technology
Press moulding mode is adopted in the production of shaped as frame stator coil at present basically, workpiece is directly compressed by foundary weight with the blue clamping device of card, plays crucial effects so block blue clamping device in the production process of whole winding.The blue crossbeam of present normally used card is an overall structure, hold-down bolt compresses coil by the screw thread on the crossbeam, the pressures partially of hold-down bolt is a hexagon, because the blue working temperature of card is approximately about 185 ℃, bolt screw thread in the course of the work is very easily impaired, the also easy stress deformation of hexagonal part, thereby influence its pressurization dynamics, make the sectional dimension of coil be difficult to guarantee, cause the coil scrappage to raise, simultaneously owing to be heated, stressed frequent fracture is finished a unit coil and need be changed a plurality of cards orchids, and promptly having influenced manufacturing schedule has wasted a large amount of raw material.
Summary of the invention
The utility model provides a kind of long-lived card blue clamping device for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the blue clamping device of a kind of card comprises hold-down bolt, crossbeam, cylindrical nut, hook, groove face briquetting, Ka Laner, the clamping head of hold-down bolt are cylindrical, and have two circular holes of cruciform shape.
Described crossbeam is split type, and in middle part and round nut welding, the nut height is greater than crossbeam thickness.
The screw thread of described bolts and nuts is a trapezoidal thread.
Advantage and the good effect that the utlity model has are: cooperating between hold-down bolt and crossbeam is that trapezoidal thread and its length of fit that extends make the blue stressed intensity enhancing of card, and the top of bolt uses the right-angled intersection hole not only to make things convenient for the rotation of workman's all directions but also increase manual clamping force; After scrapping, can weld again the trapezoidal thread round nut; Hook is changed length arbitrarily according to different workpieces.This cover card orchid has prolonged useful life, is changed into split typely by integral type, has strengthened interchangeability, has saved cost of manufacture.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the utility model comprises hold-down bolt 2, crossbeam 3, and cylindrical nut 1, hook 6, groove face briquetting 5 blocks blue ear 4.Characteristics of the present utility model are: one, increased the length of hold-down bolt 2, and the hexagon clamping head has been changed into cylindrical, and had two circular holes of cruciform shape, regular screw threads have made trapezoidal thread into; Two, crossbeam 3 changes split type Welding Structure into, and welds the round nut 1 of trapezoidal thread in the middle part, and nut 1 height is greater than crossbeam 3 thickness; Three, the length of hook 6 can be carried out the seriation design according to workpiece inclination angle difference.
