Abstract

The utility model relates to the technical field of forging and pressing equipment, in particular to a shockproof forging hammer machine which comprises a machine frame, an anvil block, a working cylinder, a hammer rod, a hammer head and an anvil cushion. The anvil block is located at the bottom of the machine frame, the working cylinder is mounted on the top of the machine frame, the hammer rod is connected to the working cylinder, the hammer head and the anvil cushion are connected to the bottom of the hammer rod and the top of the anvil block respectively, and supports and a guide rail are arranged on the anvil block. The supports are connected to the bottom of the anvil block in a rotating mode, damping rods are connected between the anvil block and the side portions of the supports, impact force is transmitted to the damping rods and the supports through the anvil block, when hydraulic buffering is carried out, the supports expand outwards, the direction of force is changed from the longitudinal direction to the horizontal direction, direct impact in the vertical direction is avoided, shock is effectively relieved, noise is reduced, forging and pressing quality is greatly improved, and the service life of a forging machine is prolonged.

Description

Shockproof forging hammer machine

Technical field

The utility model relates to technical field of forging and pressing equipment, especially a kind of shockproof forging hammer machine.

Background technology

Forging hammer is that a kind of transmission mechanisms such as air pressure or hydraulic pressure that utilize fall, and produces and moves and accumulate kinetic energy, in the extremely short time, imposes on forging, makes it to obtain plastic deformation ability, completes the metal forming machinery of various Forging Technologies.Existing forging hammer is all to adopt the tup of elevating movement to impact the anvil that is fixed on below, forging is forged and pressed, this mode that vertically impacts is by the direct going down of active force, the vibrations that cause are very large, although being set, cushion can play certain mitigation, but the direction that could not fundamentally change power, causes effect unsatisfactory, the service life of impact forging and stamping quality and equipment.

Utility model content

Large in order to overcome existing forging hammer vibrations, a little less than buffer capacity, the deficiency in the service life of impact forging and stamping quality and equipment, the utility model provides a kind of shockproof forging hammer machine.

The utility model solves the technical scheme that its technical problem adopts: a kind of shockproof forging hammer machine, comprise frame, anvil block, working cylinder, hammer stem, tup and anvil pad, anvil block is positioned at the bottom of frame, working cylinder is arranged on the top of frame, hammer stem is connected on working cylinder, tup and anvil pad are connected to the bottom of hammer stem and the top of anvil block, and anvil block is provided with support and guide rail.

According to another embodiment of the present utility model, further comprise that support is "eight" shape hydraulic stem, is rotatably connected in the bottom of support.

According to another embodiment of the present utility model, further comprise between anvil block and the sidepiece of support and be connected with damper rod.

According to another embodiment of the present utility model, further comprise that the bottom of support is slidably connected by slide block and guide rail.

According to another embodiment of the present utility model, further comprise that slide block is provided with control valve.

According to another embodiment of the present utility model, further comprise that the two ends of guide rail are provided with buffer board.

The beneficial effects of the utility model are, the support of "eight" shape hydraulic structure is rotatably connected in the bottom of anvil block, and between the sidepiece of anvil block and support, be connected in addition damper rod, the bottom of support is slidably connected by slide block and guide rail, during forging and stamping, impulsive force passes to damper rod and support by anvil block, when carrying out hydraulic cushion, support outwards struts, the direction of change power, from longitudinally becoming laterally, further by the damping between slide block and guide rail, slide and carry out the absorption of energy, dissolve by stopping of buffer board, avoided the direct shock in vertical direction, vibrations have effectively been alleviated, reduced noise, greatly improved forging and stamping quality, the service life of the forging machine extending.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model.

1. frames in figure, 2. anvil block, 3. working cylinder, 4. hammer stem, 5. tup, 6. anvil pad, 7. support, 8. guide rail, 9. damper rod, 10. slide block, 11. control valves, 12. buffer boards.

The specific embodiment

If Fig. 1 is structural representation of the present utility model, a kind of shockproof forging hammer machine, comprise frame 1, anvil block 2, working cylinder 3, hammer stem 4, tup 5 and anvil pad 6, anvil block 2 is positioned at the bottom of frame 1, working cylinder 3 is arranged on the top of frame 1, hammer stem 4 is connected on working cylinder 3, and tup 5 and anvil pad 6 are connected to the bottom of hammer stem 4 and the top of anvil block 2, and anvil block 2 is provided with support 7 and guide rail 8.Support 7 is "eight" shape hydraulic stem, is rotatably connected in the bottom of support 7.Between the sidepiece of anvil block 2 and support 7, be connected with damper rod 9.The bottom of support 7 is slidably connected by slide block 10 and guide rail 8.Slide block 10 is provided with control valve 11.The two ends of guide rail 8 are provided with buffer board 12.

The support 7 of "eight" shape hydraulic structure is rotatably connected in the bottom of anvil block 2, and between the sidepiece of anvil block 2 and support 7, be connected in addition damper rod 9, the bottom of support 7 is slidably connected by slide block 10 and guide rail 8, during forging and stamping, impulsive force passes to damper rod 10 and support 8 by anvil block 2, when carrying out hydraulic cushion, support 8 pressurizeds outwards strut, the direction of change power, from longitudinally becoming laterally, further by the damping between slide block 10 and guide rail 8, slide and carry out the absorption of energy, dissolve by stopping of buffer board 12, control valve 11 on slide block 10 can change the frictional force between slide block 10 and guide rail 8, damping adjusting coefficient, improve damping effect.By a series of combination, cushion, curve is dissolved, and has avoided the direct shock in vertical direction, has effectively alleviated vibrations, has reduced noise, has greatly improved forging and stamping quality, the service life of the forging machine of prolongation.
