Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of forging press technology, and specifically relates to a forging press and an anvil cooling system thereof. BACKGROUND

[0002] In the forging process, the upper anvil of the forging press works in a high-temperature environment for a long time, and due to the lack of effective cooling measures, the upper anvil is prone to thermal deformation. This thermal deformation not only changes the fitting precision between the anvil seat and the upper anvil, affects the stress distribution during forging, and causes the forged product to have size deviation, poor surface quality and other quality problems; but also accelerates the change of the internal organizational structure of the anvil seat and the upper anvil material, causing the material performance to decrease. Therefore, it is necessary to design a corresponding cooling system for the upper anvil of the forging press. Patent No. 202020993327.4 discloses a cooling mechanism of a forging press for petroleum mechanical part machining, which cools and cools the upper anvil by embedding a cooling water pipe in the forging hammer (upper anvil), thereby improving the continuous operation capacity of the forging press.

[0003] Different upper anvils of different specifications need to be frequently replaced according to different forging requirements. However, the traditional upper anvil connection structure is extremely inconvenient to replace and is very dependent on tedious manual assembly and disassembly operations. This problem will be more prominent when combined with the above-mentioned upper anvil cooling system. UTILITY MODEL CONTENTS

[0011] Furthermore, a power mechanism is provided on the crossbeam, and drives the plug-in portion to rise and fall via a guide rod.

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] like Figures 1-3 As shown, the upper anvil cooling system includes a coolant tank 8 and an air-cooled radiator 6 mounted on the forging press beam 12, with a cooling pipe embedded in the upper anvil 7. The coolant tank 8, air-cooled radiator 6, and upper anvil 7 are interconnected via a circulation pipeline 10. A circulating pump 9 is provided within the coolant tank 8, circulating the coolant in the order of coolant tank 8, upper anvil 7, air-cooled radiator 6, and coolant tank 8, dissipating heat and cooling the upper anvil 7.

[0034] The cooling tubes in the upper anvil 7 are arranged in a serpentine shape, wherein the gaps between the cooling tubes decrease as they move downwards. This arrangement increases the heat dissipation efficiency of the upper anvil.

[0035] In order to achieve rapid disassembly and replacement of the upper anvil, this embodiment provides the following design:

[0036] like Figure 4 As shown, a connecting seat 13 is provided at the bottom of the forging press crossbeam 12 for connecting and mounting the upper anvil 7. A slot is provided on the underside of the connecting seat 13, and a matching tenon is provided on the top of the upper anvil 7. The slot can be a dovetail slot, T-slot, or other similar slot that can provide a snap connection function.

[0037] To ensure the stability after clamping, prevent the upper anvil 7 from sliding out of the side. A slot 14 is formed on the top of the tenon of the upper anvil 7, and a plug-in part 15 with a matching shape and size is arranged in the connecting seat 13, and the plug-in part 15 can be movably arranged in the slot. The top end of the plug-in part 15 is connected with a guide rod 5, the guide rod 5 is penetrated through the top of the cross beam 12 and connected with an external power source, so as to drive the plug-in part 15 to ascend and descend. When the upper anvil 7 is clamped in place, the plug-in part 15 is inserted into the slot 14 from top to bottom, so as to lock the upper anvil 7. Of course, in order to ensure that the upper anvil 7 can be smoothly disassembled, sufficient space should be left in the slot for the plug-in part 15 to rise to completely separate from the slot 14.

[0038] As shown in Figure 1 , the cross beam 12 is provided with a gas cylinder 1 as a power source to drive the guide rod 5 to ascend and descend. The transmission mechanism between the gas cylinder 1 and the guide rod 5 is that the top of the guide rod 5 is connected to a lifting platform, and the lifting platform is connected to the cross beam 12 through a plurality of guide columns 3; the lifting platform and the guide columns 3 are in sliding connection and can slide up and down. The gas cylinder 1 is vertically arranged on the upper side of the lifting platform through the plurality of guide columns 3, and the gas cylinder 1 is connected with the lifting platform through a connecting rod mechanism 2. The gas cylinder 1 drives the plug-in part 15 to ascend and descend through the connecting rod mechanism 2, the lifting platform and the guide rod 5 in sequence; wherein when the plug-in part 15 is completely inserted into the slot 14, the connecting rod mechanism 2 is just at its dead point position, so that the lifting platform cannot push the connecting rod mechanism 2 upward, so as to realize the locking of the position of the plug-in part 15. A limiter 4 is arranged on the guide column 3, so as to prevent the gas cylinder 1 from pushing the connecting rod mechanism 2 downward beyond the dead point position.

[0039] As shown in Figure 1 , the inlet and outlet of the cooling pipe in the upper anvil 7 are arranged at the slot 14. Correspondingly, two pipe interfaces are arranged on the plug-in part 15 of the guide rod 5, which are opposite to the inlet and outlet of the cooling pipe in the upper anvil 7; the pipe interfaces and the inlet and outlet of the cooling pipe are connected in a socket type connection mode, and a sealing ring 11 is arranged to ensure sealing, so as to complete the butt joint with the cooling pipe in the upper anvil 7 after the plug-in part 15 falls down. The guide rod 5 is a hollow structure, and a circulating pipeline 10 is connected with the pipe interfaces on the plug-in part 15 through the guide rod 5, so as to realize the communication between the circulating pipeline 10 and the upper anvil 7.

[0040] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0041] The utility model is not limited to the above implementation, any obvious improvement, replacement or deformation that the person skilled in the art can make without departing from the essential content of the utility model belongs to the protection scope of the utility model.
