Description of the Invention (1) Technical Field The present invention relates to a dynamic balancer for compensating the inertial force generated by the vertical reciprocating movement of the sliding member of the press. Background When a slider of a press performs vertical reciprocating motion, the resulting inertial force will cause vibration in the press according to the size (mass) of the slider, the number of strokes (strokes per minute (spm)), and the like. , Which will affect the results of the operation of the press. To prevent this, it is common to use a dynamic balancer (DB) that has a mass approximately equal to the mass of the slider and operates in the opposite way. Fig. 1 shows a conventional dynamic balancer. In Fig. 1, the frame of a press 100 includes a top 101, a machine tool 103, four pipe strings 102, and most of them pass through the top 101, A connecting rod (not shown) for connecting the pipe string 102 and the machine tool 103 together. A slider 104 is arranged below the top 10 丨 (above the machine tool 103) and can be vertically reciprocated because it is guided along the guide column 105. A bracket 106 is fixed to the top surface of the machine tool 103 And facing the bottom surface of the slider 104. A bottom mold (not shown) of a compression mold is fixed on the top surface of the bracket 106, and a top mold is fixed on the bottom surface of the sliding member 104. In the press 100, the work piece is processed by the molds (upper mold and lower mold) not shown in the figure when the slider 104 performs a vertical stroke. The vertical stroke of the slider 104 is driven by a driving mechanism 110 built in the top 101, and the driving mechanism 110 has a crank shaft 111 supported by the projections 1123 and 1121) to be rotatable. A flywheel 113 is fixed to the right end of the crank shaft m. The flywheel 113 is driven by a motor (not shown) to generate rotation, and this paper size applies the Chinese National Standard (CNS) A4 specification (210X297).

Description of the invention (2) The rotation energy of the flywheel is provided by a clutch and braking device 114 provided on the flywheel U3. It is transmitted to the crank shaft in. A slider driven centrifugal part 11 la is arranged in the middle of the crank shaft u 丨, and the end of the connecting rod 115 having a larger size is rotatably connected to the slider driven centrifugal part 丨 丨 a through a shaft sleeve 116, the other In one aspect, a plunger 108 is provided on the slider 104 via a die height adjustment device 107, and is guided freely by a plunger guide member 107 to perform a vertical stroke. The smaller end of the connecting rod 115 is connected to the plunger 108. As for the mold-direction adjusting device 107, at the bottom end of the plunger 108, a threaded portion 108a and the inner edge of a scorpion wheel 107a are matched, and the worm wheel i07a can be at a horizontal plane. It rotates freely inside and it is held in position by a holding member 107 (: holding position. The worm 107a is driven by a motor (not shown) to rotate, so when the worm 107b rotates to drive the worm wheel 170a, it slides. Piece 104 (worm gear i07a) moves up and down relative to plunger 108 (thread portion 108a) to adjust the die height (as shown by DH in Figure 1). The driving mechanism 110 has a dynamic balancer 120, the dynamic balancer 12 has the eccentric part of the slider driving on the crank shaft 111 丨 ia DB (dynamic balancer) driving eccentric parts 111 b and 111 c, db driving eccentric parts 11 lb and 111 c is set opposite to the eccentric part driven by the slider 丨 丨 丨 a.

Description of the invention (The mass of 3 is roughly equal to the slider 104 and all connected to the slider The total weight of 104 (die height adjustment device 107, etc.) 习 The conventional press 100 (drive mechanism 110, dynamic balancer 120, etc.) constructed as described above has many disadvantages. For example, in a conventional press, Although iron is in fact a single-point press, it must still have eccentric parts on three of the crankshafts. Such a crankshaft with three eccentric parts is difficult to manufacture (car light installation) and the manufacturing cost is high. In addition, Since it has DB drive eccentric parts on both sides of the drive eccentric part of the slider, the plunger (the big end of the slider's connecting rod (slide drive eccentric part) must be made larger than used for the DB Drive eccentricity Parts. #The direct control of the inner hole of the big end (eccentric part of the slider) becomes larger, and the peripheral speed on the hole increases, which will cause the temperature of the special part to rise and break with lubrication, which is not good To increase the number of slider strokes per minute. Another way to avoid increasing the large end of the connecting rod (eccentric part of the slider driving) is to form the large end of the connecting rod with a separate structure, but it will increase the manufacturing cost And make the press heavier. Summary The purpose is to provide a dynamic balancer for a press, which is lightweight and suitable for increasing the operating speed of the press and for reducing manufacturing costs, for example, reducing the number of components to achieve the purpose of reducing costs. A dynamic balancer for a press includes a Db driven eccentric portion, which is mounted on a crank shaft to operate in the opposite phase to a slider driven eccentric portion also mounted on the crank shaft; and a DB connection A rod for connecting the DB driving eccentric at its large end and a balance weight at its small end; wherein the balance weight is formed in a way that it can be set at one end of this paper.

Due to the configuration of the present invention, the number of connecting rods (DB connecting rods) to be connected to the balance weight is two. Reduced to one. The balance weight is formed to be rotatable and includes various components (hardware) for achieving this purpose, but it is important that it does not require a balance weight guide, etc., so that it can reduce parts as a whole Number and manufacturing cost of the entire dynamic balancer. In addition, since there is no eccentric part on one side of the crank shaft, it is not necessary to add the eccentric part of the slide drive when the connecting rod connecting the slide is assembled on the crank shaft (eccentric part of the slide drive). Diameter or separate the big end of the connecting cup. Since it is not necessary to increase the diameter of the eccentric portion of the drive of the slider, it becomes very advantageous in increasing the operating speed of the press; in addition, the weight of the press can be reduced because it does not need to be separated. Line 丨 Although the balance weight rotates, the center of gravity of the balance weight is always approximately in line with the plumb line passing through the weight of the slider. Therefore, the inertia force of the slider and the balance weight cancel each other out, thereby providing The advantage of suppressing the vibration of the press due to the stroke of the slider as in the prior art. Therefore, compared with the conventional press, the dynamic balancer of the present invention can not only reduce the manufacturing cost of the dynamic balancer (press), but also provide a dynamic balancer for a press, which is suitable for increasing the The operating speed of the press reduces the weight of the press.

This structure allows the connecting rod that connects the slider to share a common part with the connecting rod that connects the balance weight. By sharing a part, the cost of manufacturing the part can be reduced due to mass production.

Description of the invention (The s-axis system is before the press 300 (M2 4Fj). Its function is similar to that of the first embodiment (2 '). In this second In the embodiment, one line can share the same parts as the 誃 -heavy DB connecting rod, which is the same as the connection 誃 balance 黻 / month ，, so in addition to having the first implementation + 仟 and therefore the same parts, the cost is reduced. The shortcomings of the conventional device can be overcome through the mass production of the device of the present invention, and advantages that cannot be obtained by the multiple known structures can be provided. For example, in the device of the present invention, the slider drive eccentric part and the DB drive Both eccentric parts can use the same straight shaft, so the diameter of the eccentric part driven by the slider can be reduced. This makes the peripheral speed of the eccentric part driven by the slider reduced, so from the perspective of temperature rise and lubrication problems It is very advantageous when the operating speed of the press (slider) is to be increased. Therefore, it provides a dynamic balancer suitable for a press that operates at a faster speed. In addition, because the number of eccentric parts is determined by 1Go to Technology Two Reduced to two, the manufacturing cost of the crankshaft can be reduced. Because the number of DB connecting rods is also reduced from two to ... the manufacturing cost of the press can be reduced again. Over refined Although the present invention has been specifically referred to its preferred embodiment It has been shown and explained, but those skilled in the art can understand that various changes can be made to the consumption and rural festivals without departing from the God and Fan 4 of the present invention.
