Abstract
The utility model discloses a clamping device for a travelling table of a hydraulic press. Four mounting holes are formed on a travelling table and in the positions corresponding to lower cross beams, clamping oil cylinders are fixedly mounted below mounting holes of the lower cross beams, piston rods of the clamping oil cylinders penetrate the mounting holes upwards, clamping blocks are mounted at the top ends of the piston rods, travelling table pressure plates are arranged below the travelling table and locked and fixed with the lower cross beams; a piston rod cavity of every clamping oil cylinder is connected with an upper-cavity oil passage and a lower-cavity oil passage respectively; and cylinder covers are mounted on the lower end surfaces of the clamping oil cylinders. Since the clamping device for the travelling table of the hydraulic press is adopted, the installation space is reduced, the travelling table can be clamped fast and easily in both lifting and falling processes, and the action coordination of the whole hydraulic press is greatly improved, and the installation location can be saved to achieve a reasonable layout.
Description
Technical field
The utility model relates to the movable workbench of hydraulic press clamping device, more specifically says so to be applied in travelling table clamping device in the hydraulic press that the Tape movement workbench moves in and out.
Background technology
In the hydraulic press that present known Tape movement workbench moves in and out, shift out and fall clamping for the rise of travelling table, be to realize by 4 that are installed in sill knockdown lifting clamping cylinders, the weak point of this structure is that the user is when having specific (special) requirements, as to the size of hydraulic die cushion and stationary work-table size when disproportionate, unusual difficulty just when sill design and installation position.
The utility model content
The purpose of this utility model provides a kind of movable workbench of hydraulic press clamping device, adopt the movable workbench of hydraulic press clamping device, dwindled installing space, can make the rise of travelling table and fall and clamp action easily and fast, greatly improve the coordination of hydraulic press complete machine, can save the installation site to reach rational layout.
The technical solution of the utility model is as follows:
The movable workbench of hydraulic press clamping device, on travelling table and sill correspondence position, have four installing holes, the installing hole below of sill is installed with clamping cylinder, the piston rod of clamping cylinder is upward through installing hole, the top of piston rod is equipped with clamp, there is the travelling table pressing plate below of travelling table, and clamp is fixedly clamped travelling table pressing plate and sill; The rod end chamber of described clamping cylinder is connected with the epicoele oil duct respectively, cavity of resorption has, and on the lower surface of clamping cylinder cylinder cap is installed.
The outside of described travelling table pressing plate is provided with the guiding cushion block, and the sidewall of clamp vertically slides along the guiding cushion block.
The utility model, is contacted with four travelling table pressing plates of travelling table under the pulling force of clamping cylinder by clamp when the travelling table operate as normal, travelling table being fixed on the sill tightly; When travelling table need shift out sill and carries out die change, clamp rose under the thrust of clamping cylinder, broke away from the travelling table pressing plate, make travelling table under the drive of reductor light and fast shift out sill.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model adopts the movable workbench of hydraulic press clamping device, has dwindled installing space, and the rise of travelling table is moved easily and fast with falling clamping, greatly improves the coordination of hydraulic press complete machine.
Description of drawings
Fig. 1 is the installation site figure of the utility model on hydraulic press.
Fig. 2 is the utility model clamped position structural representation.
Fig. 3 is the utility model released position structural representation.
The specific embodiment
As shown in Figure 1, movable workbench of hydraulic press clamping device in the present embodiment, be included on sill (3) outer panel four installing holes are set, be vertically mounted on four clamping cylinders (2) on the four direction in sill (3) outside with hold-down screw, guiding cushion block (5) is fixed on the below of clamp (4), in travelling table (1) and clamping cylinder (2)) the corresponding 4 travelling table pressing plates (14) that are provided with.
As shown in Figure 2, piston cylinder (8) is two-way cylinder, and piston rod (6) end is provided with clamp (4), and piston and piston rod are to be fixed into integral body by nut (11), and its rod end chamber is communicated with epicoele oil duct (9), and plunger shaft is communicated with cavity of resorption oil duct (13).
In concrete the enforcement, as shown in Figure 1, when the travelling table operate as normal, hydraulic oil enters rod end chamber from epicoele oil duct (9), and promotes piston rod (6) and move down, and piston rod (6) drives clamp (4) and moves down, up to contacting with pressing plate (14) position of travelling table, because clamp is under the high pressure pulling force of clamping cylinder, contact with 4 block pressur plates (14) of travelling table, so travelling table quilt being fixed on the sill tightly.
As shown in Figure 3, when travelling table (1) need shift out sill (3) and carries out die change, hydraulic oil enters plunger shaft from cavity of resorption oil duct (13), and promotion piston head (10) moves up, making piston rod (6) drive clamp (4) moves up, up to breaking away from travelling table pressing plate (14) position, travelling table (1) under the drive of reductor light and fast shift out sill (3).
Claims (2)
1. movable workbench of hydraulic press clamping device, on travelling table and sill correspondence position, have four installing holes, it is characterized in that: the installing hole below of sill is installed with clamping cylinder, the piston rod of clamping cylinder is upward through installing hole, the top of piston rod is equipped with clamp, there is the travelling table pressing plate below of travelling table, and clamp is fixedly clamped travelling table pressing plate and sill; The rod end chamber of described clamping cylinder is connected with the epicoele oil duct respectively, cavity of resorption has, and on the lower surface of clamping cylinder cylinder cap is installed.
2. movable workbench of hydraulic press clamping device, it is characterized in that: the outside of described travelling table pressing plate is provided with the guiding cushion block, and the sidewall of clamp vertically slides along the guiding cushion block.
