Description

Punching structure of hydraulic forging press

Technical Field

The utility model relates to a forging equipment technical field especially relates to a structure of punching a hole of forging hydraulic press.

Background

With the rapid development of the forging industry, the requirement on the tonnage of forging of a hydraulic forging press is higher and higher, the precision requirement on a workpiece is higher and higher, and for small-sized forgings such as flanges and the like, punching after blank manufacturing is required. The existing punching structure is usually realized by a large-sized punch, and the punch usually uses bench clamps and the like when clamping and fixing a workpiece, so that the punch is inconvenient to adjust, cannot adjust and compress the fixed position according to the size of the workpiece, and causes the workpiece to slide during machining, thereby influencing the machining quality.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a punching structure of a hydraulic forging press.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a forging hydraulic press's structure of punching a hole, includes punch press body, fixed plate and closing device, the punch press body includes punch press base, punch press bearing platform and punching press head, and punch press bearing platform sets up on the punch press base, the punching press head is located punch press bearing platform directly over, two the fixed plate sets up the both sides at punch press bearing bench respectively, and all is equipped with the cylinder on the fixed plate, the end of piston rod is equipped with the movable plate in the cylinder, closing device includes threaded rod, compressing head and handle, and the threaded hole screw-thread fit who sets up on threaded rod and the movable plate, the compressing head rotates with the bottom of threaded rod to be connected.

Preferably, the handle is welded to the top end of the threaded rod.

Preferably, the punch press bearing table is provided with a punching groove.

Preferably, the punching groove is positioned right below the punching head, and the punching head is matched with the punching groove.

Preferably, the pressing head is made of a rubber material.

Compared with the prior art, the utility model discloses can adjust to compress tightly fixed position according to the size of machined part, thereby avoided adding man-hour, thereby the machined part takes place to slide and has influenced processingquality.

Drawings

Fig. 1 is a schematic front view of a punching structure of a hydraulic forging press according to the present invention;

fig. 2 is an enlarged schematic structural diagram of a position a of the punching structure of the hydraulic forging press according to the present invention.

In the figure: the punching machine comprises a punching machine body 1, a punching machine base 2, a punching machine bearing table 3, a punching head 4, a fixing plate 5, a cylinder 6, a moving plate 7, a pressing device 8, a threaded rod 81, a pressing head 82, a handle 83 and a punching groove 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a punching structure of a forging hydraulic press, including punch press body 1, fixed plate 5 and closing device 8, punch press body 1 includes punch press base 2, punch press bearing platform 3 and punching press head 4, and punch press bearing platform 3 sets up on punch press base 2, punching press head 4 is located punch press bearing platform 3 directly over, two fixed plates 5 set up the both sides on punch press bearing platform 3 respectively, and all be equipped with cylinder 6 on fixed plate 5, the end of piston rod is equipped with movable plate 7 in the cylinder 6, closing device 8 includes threaded rod 81, closing head 82 and handle 83, and threaded rod 81 and the threaded hole screw-thread fit who sets up on the movable plate 7, closing head 82 rotates with the bottom of threaded rod 81 to be connected, handle 83 welds the top at threaded rod 81, closing head 82 is made by rubber materials.

Wherein, be equipped with the die cavity 9 on the punch press bearing platform 3, the die cavity 9 is located punching head 4 under, and punching head 4 and die cavity 9 phase-match, and the drive arrangement drive punching head 4 among the punch press body 1 pushes down, and punching head 4 cooperates die cavity 9 to punch a hole the processing to the machined part.

Example (b): place the machined part on punch press bearing platform 3, open cylinder 6, cylinder 6 drive movable plate 7 moves to suitable position, rotates handle 83, and handle 83 drives threaded rod 81 and rotates, and threaded rod 81 drives the pressure head 82 and removes, and pressure head 82 is held the machined part pressure and is fixed, and this device can adjust according to the size of machined part and compress tightly fixed position, thereby has avoided adding man-hour, thereby the machined part takes place to slide and has influenced processingquality. The driving device in the punch body 1 drives the punch head 4 to press down, and the punch head 4 is matched with the punching groove 9 to punch a hole on a workpiece.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
