[0002] In today's forging process, in order to achieve high efficiency and high productivity, the die forging machine must have a higher number of strokes per unit time, that is, a faster stroke speed, and often needs to be equipped with automated equipment to achieve 24-hour uninterrupted output operations.

[0003] However, the combined clutch-brake in the prior art is integrated and installed on the crankshaft and one end of the flywheel, which causes unbalanced force on the left and right ends of the die forging machine, making the crankshaft and related matching parts and bearings prone to excessive wear, thereby affecting the working accuracy and efficiency. Such a combined clutch-brake structure, such as the combined brake clutch disclosed in patent number CN203176237U, adopts this installation form and has the following disadvantages:

[0004] (1) The unbalanced force of the die forging machine and the large instantaneous inertia during operation cause the crankshaft and related parts and bearings to be easily excessively worn.

[0005] (2) It is easy to cause abnormal wear of the brake pads and friction plates, which will reduce the braking performance and be dangerous to the use of equipment or molds.

[0027] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 of the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 3 As shown, the high-speed die forging machine in this embodiment includes a main frame 10, in which a slider assembly 20 is arranged to be liftable. The slider assembly 20 is conventionally composed of a slider 21, a connecting rod 22 and a slider spindle 23 inserted therebetween. The slider 21 can be lifted and lowered in the main frame 10 by rotating the connecting rod 22, thereby realizing the stamping action. This is a conventional structure in the field and is not further limited here.

[0030] Specifically, an eccentric shaft 30 is inserted into the slider assembly 20 , specifically, the connecting rod 22 , and both ends of the eccentric shaft 30 extend outward from the main frame 10 .

[0031] Among them, a brake 40 is provided at one end of the eccentric shaft 30, and a flywheel 50 is provided on the same side as the brake 40 and in transmission cooperation. The flywheel 50 is driven to rotate by a motor 51. A fixed seat 11 is provided on the rear side of the main frame 10, and the fixed seat 11 is used to support the motor 51. The motor 51 and the flywheel 50 are connected by a belt 53.

[0032] In addition, a first transmission wheel 60 is provided at the other end of the eccentric shaft 30, and a clutch 70 is provided on the same side of the first transmission wheel 60. The clutch 70 is used to control the clutch cooperation between the eccentric shaft 30 and the first transmission wheel 60. A transmission shaft 52 is linked to the flywheel 50, and a second transmission wheel 61 is provided at the end of the transmission shaft 52. The second transmission wheel 61 is used to drive the first transmission wheel 60 to rotate, and the first transmission wheel 60 is used to drive the eccentric shaft 30 to rotate, and the eccentric shaft 30 is used to drive the slider assembly 20 to make a lifting movement.

[0033] Among them, the transmission shaft 52 is located at the rear side of the main frame 10, the brake 40 and the clutch 70 are respectively located on the left and right sides of the main frame 10, the brake 40 and the clutch 70 are coaxially arranged, the flywheel 50 and the motor 51 are located at the rear side of the brake 40, the second transmission wheel 61 is located at the rear side of the clutch 70, and the motor 51 is located obliquely above the flywheel 50 and at the rear side of the main frame 10.

[0034] When the die forging machine as a whole starts to operate, the motor 51 is operated and the belt 53 drives the flywheel 50 to rotate, and the flywheel 50 transmits kinetic energy to the transmission shaft 52 and the second transmission wheel 61, and the first transmission wheel 60 is driven to operate through the tooth meshing of the second transmission wheel 61. After the first transmission wheel 60 stores energy, it transmits energy to the eccentric shaft 30 through the clutch 70 that can be controlled pneumatically, so that the eccentric shaft 30 can rotate. This eccentric rotation makes the connecting rod 22 present a circular motion. Because the slider spindle 23 combines the slider 21 and the connecting rod 22 together, and the slider 21 is constrained in the front, rear, left and right four directions inside the frame 10, when the eccentric shaft 30 rotates, it will drive the slider 21 to present a vertical upward and downward reciprocating motion. At this time, when the slider returns to the top dead center, the brake 40 is pneumatically controlled to stop the brake.

[0035] The die forging machine in this embodiment can meet current processing requirements and can be easily matched with automation to provide continuous, uninterrupted and rapid operating efficiency.

[0036] All the methods described herein can be performed in any suitable order. Any and all examples used, or exemplary language provided herein (such as "for example") are merely to better illustrate the present invention, and are not intended to limit the scope of the present invention, unless the claims are included.
