Description

Technical Field

[0001] The utility model relates to the technical field of track forging production, in particular to a track forging shaping device for an engineering vehicle. Background Art

[0002] Engineering vehicles are generally equipped with tracks as a means of movement. The tracks are mainly driven by a driving wheel and are composed of a flexible chain ring around the driving wheel, road wheels, idler wheels and track rollers. The flexible chain ring is composed of track shoes and track pins.

[0003] In the production process of crawler tracks equipped on engineering machinery, the track plates, i.e., the track frames, are produced by forging. After forging and forming, they need to be heat treated to give them good mechanical properties. After heat treatment, the long crawler plates will have certain bending deformations, so correction and shaping equipment is required for extrusion and straightening. The existing straightening equipment mainly straightens by applying pressure to the bending position. The reverse bending in some areas cannot be adjusted by applying pressure, and the track frame needs to be repeatedly turned over. The straightening support equipment has a fixed support position, which affects the straightening effect. During the correction process, the forgings will extend outward, and the existing support equipment has a large contact surface, which has a certain obstacle to the outward extension. Utility Model Content

[0008] The support assembly mainly supports the track frame forgings that need to be reshaped. The movable support assembly can change the support position to meet the needs of reshaping from top pressure or lifting from the bottom.

[0009] In a preferred embodiment of the utility model, the vertical section of the clamping groove is L-shaped, and inside the sliding frame, mounting grooves cooperating with the upper roller and the lower roller are provided at the inner side and the bottom of the top of the clamping groove;

[0010] When the L-shaped clamping groove is pressurized and shaped from the top, the bottom of the groove plays a supporting role, and when the L-shaped clamping groove is pressurized and shaped from the bottom upward, the raised position on the top of the clamping groove plays a limiting role.

[0011] In a preferred embodiment of the present invention, the lifting bar is located outside the bottom of the pressure bar, and the positions of the lifting bar and the pressure bar correspond to the positions of the clamping grooves.

[0013] The sliding frame can slide on the surface of the processing table to change the supporting position when pressure is applied, so as to better meet the pressure shaping support effect and ensure the shaping effect.

[0014] The beneficial effects of the utility model are:

[0015] The engineering vehicle track forging shaping device can adjust the support position of the track forging according to the needs of use, thereby changing the support position according to the bending degree and bending position. When pressure is applied, the roller in the clamping groove facilitates the bending position of the forging to extend outward, and the shaping equipment has the ability to lift and shape from bottom to top, reducing the need for frequent flipping of forgings.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0023] like Figure 1-5 The shown engineering vehicle track forging shaping device includes a workbench 1, a support frame 2, a hydraulic press 3, a pressure device 4 and a support assembly 5. The support frame 2 is fixedly arranged on the upper surface of the workbench 1, the hydraulic press 3 is fixedly arranged on the top of the support frame 2, the pressure device 4 is fixedly arranged at the telescopic end of the hydraulic press 3, and the support assembly 5 is clamped on the upper surface of the workbench 1. The pressure device 4 includes a pressure plate 41, a lifting frame 42, a pressure bar 43 and a lifting bar 44. The lifting frame 42 is fixedly arranged at the bottom of one end of the pressure plate 41, the pressure bar 43 is fixedly arranged at the bottom of the other end of the pressure plate 41, and the lifting bar 44 is fixedly arranged on the top of one end of the lifting frame 42.

[0024] Specifically, the supporting assembly 5 includes a sliding frame 51, a clamping groove 52, a lower roller 53 and an upper roller 54. The clamping groove 52 is opened at the top of the sliding frame 51, the lower roller 53 is movably installed at the bottom of the clamping groove 52, and the upper roller 54 is movably installed on the inner side of the top of the clamping groove 52. The vertical section of the clamping groove 52 is an L-shaped structure. In the sliding frame 51, mounting grooves that cooperate with the upper roller 54 and the lower roller 53 are opened at the inner side and bottom of the top of the clamping groove 52. The lifting bar 44 is located at the outer side of the bottom of the pressure bar 43, and the positions of the lifting bar 44 and the pressure bar 43 correspond to the position of the clamping groove 52. A sliding block is arranged at the bottom of the sliding frame 51, and a sliding groove that cooperates with the sliding block at the bottom of the sliding frame 51 is opened on the surface of the workbench 1, and the sliding groove on the surface of the workbench 1 is arranged horizontally.

[0025] In this embodiment, the track frame forging that needs to be shaped is first clamped into the clamping groove 52 at the top of the sliding frame 51 in the support assembly 5, and the sliding frame 51 is slid and adjusted on the surface of the workbench 1 according to the bending position, so that the pressure position is located on the outside of the bottom of the pressure bar 43, and then the hydraulic press 3 is turned on, the telescopic end of the hydraulic press 3 is controlled to extend, the pressure device 4 is lowered, and the pressure bar 43 at the bottom of the pressure plate 41 acts on the surface of the forging to press down, thereby realizing the downward pressure shaping work. At this time, the forging support position is in contact with the lower roller 53 at the bottom of the clamping groove 52. The lower roller 53 provides support for the forging and is also conducive to the extension of the pressed forging.

[0026] Furthermore, when the forging needs to be reversely pressurized, workers usually flip the forging to change the direction of pressure to perform the shaping work. The present shaping equipment only needs to push the forging forward to the bottom of the raised position of the clamping groove 52, and control the hydraulic press 3 to contract, so that the pressure plate 41 drives the lifting frame 42 to lift, and the lifting bar 44 acts on the shaping area. At this time, the upper roller 54 at the top of the clamping groove 52 plays a supporting role. During the shaping process, the upper roller 54 is easy to extend outward, so that the forging can be pressed from top to bottom or from bottom to top for shaping through the adjustable support assembly 5 and the extension and retraction of the hydraulic press 3.

[0027] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
