Description

Technical Field

[0001] The utility model relates to the technical field of forging equipment, in particular to a forging horse rack. Background Art

[0002] When forging a circular ring blank, it is necessary to first punch a through hole in the center of the cylindrical blank, and then place the blank frame on the horse frame to forge the outer peripheral surface of the blank to expand the inner diameter of the blank. The horse frame of the prior art includes a frame body and a horse lever, wherein the frame body includes a bottom plate, support plates are arranged on both sides of the bottom plate, and a groove is arranged in the center of the top of the support plate. When in use, the workpiece is first clamped by a manipulator (similar to a manipulator) and placed between the two support plates, and then the horse lever is passed through the through hole of the workpiece and its two ends are respectively placed in the grooves on the two support plates, and then forging can be performed. Since the horse lever is heavy, it is difficult for the operator to hold the horse lever and place one end of it in the groove on one support plate. Then, when the horse lever is pushed through the through hole on the workpiece with the groove as support, since the length of the horse lever is not much larger than the distance between the two support plates, when the front end of the horse lever is about to reach the other support plate, the end will sink due to the lever effect, making it difficult to place the end in the groove on the support plate. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a forging horse stand in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a forging horse frame, including a frame body and a horse lever, the frame body includes a base plate, support plates are arranged on both sides of the base plate, a groove is arranged on the top of the support plate, a first handle is arranged at one end of the horse lever, an insertion hole is arranged on the end face of the other end of the horse lever, and a retaining ring distributed along an arc shape is also arranged on the end face of the end, a retaining groove distributed along an arc shape is arranged on the inner side of the retaining ring, and also includes a second handle, one end of the second handle can be inserted into the insertion hole and the end is provided with an insert plate that can be inserted into the retaining groove when the second handle rotates.

[0005] To further optimize the technical solution, the central angle of the retaining ring is 180°.

[0006] To further optimize the technical solution, a truncated cone-shaped depression is provided at one end of the horse lever away from the first handle, the depression has a large outer diameter and a small inner diameter, and the insertion hole is located at the end of the depression with a smaller diameter.

[0007] To further optimize the technical solution, a rib plate is provided on the outer side of the support plate.

[0008] Compared with the prior art, the utility model has the following advantages: a first handle is provided at one end of the horse bar, and a second handle is detachably connected to the other end, so that two people can each stand at one end of the horse bar to lift the horse bar for placement, and it is relatively easy and labor-saving to place the two ends of the horse bar in the two grooves.

[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0015] Specific implementation method: Combination Figure 1-4 As shown, a forging horse frame includes a frame body 1 and a horse bar 2, wherein the frame body 1 includes a bottom plate, support plates are provided on both sides of the bottom plate, a groove is provided on the top of the support plate, a first handle 21 is provided at one end of the horse bar 2, a socket 22 is provided on the end face of the other end of the horse bar 2, and a retaining ring 23 distributed along a circular arc is also provided on the end face of the end, the retaining ring 23 is preferably coaxial with the socket 22, and a retaining groove distributed along a circular arc is provided on the inner side of the retaining ring 23, so that the cross section of the retaining ring 23 is L-shaped, and also includes a second handle 3, one end of the second handle 3 can be inserted into the socket 22 and the end is provided with an insert plate 31 that can be inserted into the retaining groove when the second handle 3 is rotated. The second handle 3 is detachably connected to the horse bar 2. When in use, first insert one end of the second handle 3 into the socket 22, then rotate the second handle 3 so that the insert plate 31 is located in the retaining groove on the retaining ring 23, and then two people hold the two handles respectively to lift the horse bar 2, and then as shown Figure 1As shown in the figure, one end of the second handle 3 is placed in the groove on a support plate, and then the operator at that end (hereinafter referred to as A and the other as B) releases the second handle 3 and walks to the other side of the horse lever 2, and then the operator clamps the workpiece 4 and places it between the two support plates, and then B pushes the first handle 21 so that the front end of the second handle 3 extends from the second support plate to become Figure 2 Then A lifts the extended end of the second handle 3, and B also lifts the first handle 21, so that the horse bar 2 is raised so that it can pass through the workpiece 4, and then the two ends of the horse bar 2 are placed in the two grooves respectively. At this time, the second handle 3 can be removed, and then forging can be carried out. When the forging is completed, the combination Figure 2 As shown, the workpiece 4 is first clamped by the manipulator, and then the second person holds the first handle 21 to pull the horse bar 2 to the right. When the left end of the horse bar 2 is located in the groove on the right, the manipulator takes away the workpiece 4, and then the first person installs the second handle 3 on the left side of the horse bar 2, and then the two people work together to remove the horse bar 2 from the frame 1. Since two people can lift both ends of the horse bar 2 at the same time, it is more labor-saving when placing and removing the horse bar 2.

[0016] Furthermore, the central angle of the retaining ring 23 is 180°, so that the inserting plate 31 can be easily located at a position without the retaining ring 23, so that the inserting plate 31 can be inserted into the retaining groove by rotating the second handle 3, and the inserting plate 31 will not fall off from the retaining ring 23 too easily.

[0017] Furthermore, a truncated cone-shaped depression is provided at one end of the horse lever 2 away from the first handle 21 , the depression has a large outer diameter and a small inner diameter, and the insertion hole 22 is located at the end with the smaller diameter of the depression, so that the second handle 3 is easily inserted into the insertion hole 22 .

[0018] Furthermore, a rib plate 11 is provided on the outer side of the support plate to improve the strength of the frame 1 .

[0019] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
