Description

Technical Field

[0001] The utility model relates to a high-stability forging hydraulic hammer. Background Art

[0002] At present, a Chinese patent with the authorization announcement number CN204430136U discloses a forging machine, including a frame and a forging workbench, the frame is set up in an inverted U shape, a driving component is connected to the frame, a first hammer head and a second hammer head are arranged below the driving component, the driving component, the first hammer head and the second hammer head are connected in sequence, a groove is provided on the first hammer head, the second hammer head is connected to the first hammer head through the groove, and a positioning pin for clamping and positioning the second hammer head and the first hammer head is also provided in the groove; the inner wall of the frame is also provided with a rolling cavity, a ball is embedded in the rolling cavity, and a slide groove is provided on the side wall of the first hammer head. When the driving component moves up and down, the surface of the ball and the inner wall of the slide groove are set in a conflicting manner and a rolling fit is formed between the two. The ball is arranged inside the rolling cavity to change the original sliding friction into rolling friction. The ball rolls irregularly in the slide groove of the first hammer head, reducing friction resistance and shaking, which is conducive to improving the stability when hammering.

[0003] The die material is placed on the workbench, the second hammer head moves down and forges the die material, but the forged die material needs to be rotated at a certain angle due to process requirements. The clamping device can easily flip the die material and push the die material to move horizontally, but the rotation process is relatively inconvenient. Utility Model Content

[0004] In view of this, the utility model aims to provide a high-stability forging hydraulic hammer to facilitate the rotation of the die material.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a high-stability forging hydraulic hammer, comprising a frame, a power cylinder and a workbench for placing mold materials, the power cylinder is fixed on the frame, the hydraulic shaft of the power cylinder is connected with a hammer head, the hammer head corresponds to the workbench and is slidably connected to the frame, the workbench is provided with a mounting groove near the edge, an adjusting cylinder is fixedly connected in the mounting groove, an elastic rod is connected to the side wall of the adjusting shaft of the adjusting cylinder, a straight groove is provided on the inner wall of the mounting groove, a rotating sleeve is sleeved on the adjusting shaft, the rotating sleeve is rotatably connected to the mounting groove, an oblique groove is provided on the rotating sleeve, the elastic rod passes through the oblique groove and is used to contact with the inner wall of the oblique groove, and the rotating sleeve is connected to a support plate for contacting with the mold material.

[0006] To implement the above technical solution, the mold material is placed on the workbench, and the power cylinder is turned on to move the hydraulic shaft downward and make the hammer hit the mold material, and the mold material is pushed from the center of the workbench to the support plate through the clamping device, and the adjusting cylinder is turned on, and the adjusting shaft moves along its own length direction, and moves along the length direction of the straight groove through the elastic rod, and the outer wall of the elastic rod contacts the inner wall of the inclined groove to make the rotating sleeve drive the support plate to rotate, so that the support plate rotates, and the mold material on the support plate can rotate synchronously, and then the mold material is moved to the bottom of the hammer head for further processing through the clamping device, and the operation is simple; compared with the rotation of the support plate driven by the motor, the vibration of the support plate will be directly transmitted to the motor, which is easy to cause damage to the motor, and because the adjusting shaft is retracted to the end point of the stroke and then moved forward a little distance, there is a gap between the elastic rod and the inclined groove, and the vibration of the support plate cannot be transmitted to the adjusting cylinder, so that it has a longer service life.

[0007] As a preferred solution of the utility model, the elastic rod includes a placement groove, an elastic member, and a connecting rod. The placement groove is opened on the side wall of the adjusting shaft. The elastic member is placed in the placement groove and one end is fixedly connected to the connecting rod, and the other end is fixedly connected to the inner wall of the placement groove. The end of the connecting rod away from the elastic member passes through the inclined groove and is placed in the straight groove.

[0008] To implement the above technical solution, pressure is applied to the connecting rod so that the entire connecting rod is located in the placement groove, and the rotating sleeve is arranged on the outside of the adjusting shaft. The connecting rod is located inside the rotating sleeve. As the rotating sleeve continues to move along the length direction of the adjusting shaft, when the inclined groove corresponds to the connecting rod, the elastic force of the elastic member causes the connecting rod to extend from the placement groove, pass through the inclined groove, and then be placed in the straight groove, thereby achieving the purpose of easy installation.

[0009] As a preferred solution of the utility model, the rotating sleeve is connected to the support plate through a shock absorbing structure.

[0010] To implement the above technical solution, when the surface area of ​​the mold material is large, part of the mold material is placed on the support plate and the other part is placed on the workbench. When the hammer hits the mold material, the support plate will be subjected to force. By setting the shock-absorbing structure, the protection of the rotating sleeve is improved.

[0011] As a preferred solution of the utility model, the shock absorbing structure includes a guide rod, a guide hole and a buffer spring, the guide rod is fixed to the end of the rotating sleeve, the guide hole is opened on the support plate, and the buffer spring is sleeved on the outside of the guide rod with one end connected to the support plate and the other end connected to the end of the rotating sleeve.

[0012] To implement the above technical solution, a portion of the mold material is placed on the support plate. When the support plate is subjected to downward pressure, the buffer spring will relieve most of the impact force to enhance the protection of the rotating sleeve.

[0013] As a preferred solution of the utility model, the guide rod passes through the guide hole and extends out from the guide hole.

[0014] To implement the above technical solution, part of the mold material is located directly above the support plate due to its special shape and cannot directly contact the support plate. The support plate and the guide rod rotate with the rotating sleeve, so that the guide rod contacts the side wall of the mold material, thereby realizing the rotation of the mold material and improving practicality.

[0015] As a preferred solution of the utility model, there are two guide rods which are evenly distributed along the axis of the rotating sleeve.

[0016] The above technical solution is implemented to make the process of the rotating sleeve driving the supporting plate to rotate more stably.

[0017] As a preferred solution of the utility model, a limiting ring is fixedly connected to the outer wall of the rotating sleeve, the rotating sleeve and the limiting ring are coaxially arranged, a coaxially arranged limiting groove is opened on the inner wall of the mounting groove, the limiting ring is located in the limiting groove, and an anti-slip block is fixedly connected to the opening of the limiting groove, and the anti-slip block is used to interfere with the outer wall of the limiting ring.

[0018] To implement the above technical solution, since the power of the adjusting cylinder is relatively strong, the anti-falling block abuts against the limiting ring, so that the rotating sleeve is not easy to fall out of the installation groove. BRIEF DESCRIPTION OF THE DRAWINGS
