Description

Technical Field

[0001] The present invention relates to the technical field of forging, and in particular to a forging device. Background Art

[0002] Forging is a processing method that applies pressure to the blank to make it plastically deform and obtain the corresponding product. Common forging methods are cold forging and hot forging. Hot forging is forging performed above the crystallization temperature of the metal. Increasing the temperature can improve the plasticity of the metal, which is beneficial to improving the intrinsic quality of the workpiece and making it less likely to crack.

[0003] In the existing metal cylinder processing, hot forging is often used. During processing, the metal cylinder is generally placed on a cylindrical rod. During the processing, the outer surface of the cylindrical metal rod must first be oiled, and then the outer surface of the metal cylinder must be lubricated to reduce the friction between the metal cylinder, the cylindrical rod and the extrusion device, thereby improving the extrusion effect. In actual operation, since the metal cylinder and the cylindrical metal rod are not in the same position, the operator needs to perform the oiling operation in two steps at two places, which is troublesome. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a forging device to solve the above-mentioned technical problems.

[0005] The technical solution of the present invention is as follows:

[0010] Preferably, the first oil-absorbing layer is a bristle layer or a sponge layer; the second oil-absorbing layer is a bristle layer or a sponge layer.

[0011] When the forging equipment of the present invention is used, the oil storage chamber is filled with high temperature resistant lubricating oil, the metal cylinder to be processed is pressed down to the bottom along the cylindrical inner core, and then taken out.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Example, see Figure 1 and Figure 2 The present embodiment is a forging device, comprising a support platform 1, a first bracket 2 is fixed on the support platform, a cylindrical rod 3 and a plurality of extrusion devices are installed on the first bracket, and the plurality of extrusion devices are circumferentially arranged on the outside of the cylindrical rod, the support platform is a box-type structure, an oil storage chamber 4 is arranged inside, a cylindrical inner core 5 is fixed in the oil storage chamber, and a first oil absorption layer 6 is sleeved on the cylindrical inner core; a second oil absorption layer 7 is arranged on the outside of the first bristle layer, a sleeve 8 is sleeved on the outside of the second oil absorption layer, and the second oil absorption layer is fixed on the inner wall of the sleeve; wherein the first oil absorption The first oil-absorbing layer and the second oil-absorbing layer can be oil-absorbing structures such as bristle layers or sponge layers. When fixed, the first oil-absorbing layer can be bonded to the cylindrical inner core, and the second oil-absorbing layer can be bonded to the sleeve. The outer diameter of the metal cylinder to be processed is larger than the inner diameter of the second bristle layer and smaller than the outer diameter of the second bristle layer; the inner diameter of the metal cylinder to be processed is larger than the inner diameter of the first bristle layer and smaller than the outer diameter of the first bristle layer; the bottom end of the cylindrical inner core is circumferentially provided with a plurality of extensions 5A extending outward, the bottom end of the sleeve is fixed on the extension, and the top end of the cylindrical inner core and the top end of the sleeve both extend to the outside of the oil storage chamber.

[0017] When the forging equipment is in use, the oil storage chamber is filled with high temperature resistant lubricating oil, the metal cylinder to be processed is pressed down to the bottom along the cylindrical inner core, and then taken out. During this process, the first oil absorption layer and the second oil absorption layer are squeezed to coat the absorbed lubricating oil on the inner and outer surfaces of the metal cylinder; the metal cylinder can be heated before and after being taken out, and after heating and oiling, the metal cylinder is put on the cylindrical rod, and the metal cylinder is squeezed using an extrusion device. The oiling operation of this structure does not require the operator to brush oil in two places in two steps, and the operation is relatively simple.

[0018] As a preferred embodiment, the top of the support platform is provided with an upward flange 14 at the edge position, and the top surface of the oil storage chamber is provided with a through hole 15 connected to the inside of the oil storage chamber. After the metal cylinder is taken out, once excess lubricating oil drips, it can be blocked on the inside by the flange and fall back into the oil storage chamber along the through hole. Generally, after the metal cylinder is taken out, it is rotated 180° so that the bottom and the top are interchanged and stay for about 10 seconds to allow the lubricating oil to penetrate downward to the top position to prevent the top position from lacking lubricating oil due to being higher than the oil level.

[0019] As an embodiment, the extrusion device includes a fixed plate 9, an extrusion plate 10 and a first hydraulic cylinder 11; a second bracket 12 and a second hydraulic cylinder 13 for driving the second bracket to move left and right relative to the first bracket are slidably arranged on the support platform, and the second bracket is provided with a center hole for a cylindrical rod to pass through and a receiving groove or receiving hole for accommodating one end of the fixed plate, the other end of the fixed plate is fixed on the first bracket, the hydraulic cylinder is fixed on the fixed plate, and the power output end of the hydraulic cylinder is connected to the extrusion plate. The length of the fixing plate is greater than that of the extrusion plate so that the fixing plate can be inserted into the accommodating groove or the accommodating hole when the second bracket is close to the first bracket, and the extrusion plate can be driven by the first hydraulic cylinder to move freely between the first bracket and the second bracket. Before the metal cylinder is put on the cylindrical rod, the second hydraulic cylinder can drive the second bracket to the right to separate from the cylindrical rod, leaving space for the installation of the metal cylinder. When the metal cylinder is installed on the cylindrical rod, the second hydraulic cylinder drives the second bracket to move left so that the cylindrical rod passes through the center hole and the fixing plate is inserted into the accommodating groove or the accommodating hole. In this way, the second bracket forms a support for the cylindrical rod and the fixing plate at the other end, so that when the first hydraulic cylinder drives the extrusion plate to extrude the metal cylinder, both ends of the cylindrical rod and the fixing plate are supported, and the stability is better. As a preferred solution, the cylindrical rod is rotatably connected to the first bracket; the end of the cylindrical rod close to the first bracket is located on the side of the first bracket facing away from the second bracket, and is fixed with a first gear 16; a drive motor 17 is installed on the first bracket, and a second gear 18 is fixed to the power output end of the drive motor, and the second gear is meshed with the first gear. After the metal cylinder is sleeved on the cylindrical rod, this structure can make the second hydraulic cylinder drive the second bracket to move left, clamp the metal cylinder, and then start the drive motor to drive the cylindrical rod to rotate so that the lubricating oil on the inner surface of the metal cylinder is more evenly distributed on the metal cylinder under the drive of the cylindrical rod; it is also possible not to clamp the metal cylinder first, but to fit the extrusion plate to the outer surface of the metal cylinder, and start the drive motor to make the outer surface of the metal cylinder and the extrusion plate move relative to each other, which is conducive to more uniform lubricating oil on the outer surface of the metal cylinder.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
