Abstract
The utility model discloses a dual crank pressure machine which comprises a machine body, a crank horizontally under the machine body, a dual connection bar with the two ends hinged with the crank and a sliding block, the sliding block arranged above the connection bar, a working platen under the sliding block, a flywheel arranged on the outer side under the machine body and connected with the crank through a clutch and a ball guiding device as well. The sliding block and working platen length of the dual crank pressure machine of the utility model can accommodate at least six stamping stations. The dual crank pressure machine is characterized by low gravity and short body, reduces the press machine manufacturing cost and improves the existing crank press machine die space light condition, thus being convenient for operation, installation and stamping die alternation, and improving the security of the existing crank pressure unit. The length of the sliding block can ensure the punching, blanking, repeatedly drawing and other procedures can be completed in one crank pressure machine. One crank pressure machine can replace two existing machines, thereby reducing equipment cost.
Description
Technical field
The utility model relates to a kind of crank press, and particularly a kind of underdrive crank press belongs to the press technical field.
Background technology
Crank press can be used for plastic deformation operations such as the punching, blanking, stretching, calendering of sheet metal.The bent axle of traditional crank press is horizontally placed on body upper, and flywheel is positioned at fuselage outer side, is connected with bent axle one end by clutch.During work, flywheel drives bent axle by clutch and rotates, and drives slide block by connecting rod again and moves up and down, and by the upper trimming die that is contained on the slide block sheet metal that is placed on down on the punch die is finished stamping procedures such as punching, blanking.Because bent axle and flywheel all place body upper, the center of gravity height of crank press, fuselage is huge, and maintenance is difficulty comparatively; Because four vertical side of slide block are except that the front, its excess-three face is all surrounded by slide block guide rail and fuselage, and during punching press, the light in punch die space is relatively poor, and the operative employee is difficult for observing, and stamping quality and handling safety are all had adverse effect, also is not easy to install and remove punch die.Some punching parts often need through punching, blanking, repeatedly operation such as stretching just can be finished, because the length of a crank press work top is finished multi-step forming processes inadequately, often need two crank presses to form the crank press unit side by side, utilize the length of working surface of table of two crank presses, multi-step forming processes is finished in relay, it is more to take equipment, and cost of stamping is higher.
Summary of the invention
In order to reduce the center of gravity of crank press, reduce the fuselage height, thereby reduce the manufacturing cost of crank press, can on a crank press, finish punching, blanking, multiple working procedure such as stretching repeatedly.The utility model provides a kind of double-crank forcing press, and this crank press center of gravity is low, and fuselage is shorter, has improved the light condition in existing crank press punch die space, is convenient to operative employee's operation, the security that improves existing crank press unit; The length of slide block can guarantee to finish punching, blanking, multiple working procedure such as stretching repeatedly on a crank press.
The utility model is achieved by the following technical programs:
A kind of double-crank forcing press comprises fuselage, bent axle, connecting rod, is positioned at the slide block of connecting rod top, the working plate that is positioned at the slide block below, the flywheel that is positioned at fuselage outer side and is connected with bent axle one end by clutch; Described bent axle is horizontally placed on the below of fuselage, and the middle part of described bent axle is provided with the identical double-crank of structure; Described connecting rod is the identical double link of structure, and an end of this double link is hinged with described double-crank respectively, and the other end passes behind lower platform and the working plate hinged with slide block respectively; The length of described slide block and working plate can be held at least six punching press stations, and this double-crank forcing press also comprises the ball guider.
Aforesaid double-crank forcing press, wherein said ball guider comprise the guide pillar on four angles of lower platform that are fixed on fuselage; Be fixed in four angles of slide block and the guide pin bushing that matches with described guide pillar.
Aforesaid double-crank forcing press, wherein said guide pin bushing are ball bearing guide bushing.
The center of gravity of double-crank forcing press of the present utility model is low, and fuselage is short, has reduced the manufacturing cost of forcing press, improved the light condition in existing crank press punch die space, help operative employee's operation, be convenient to install and change punch die, the security that has improved existing crank press unit; The length of slide block can guarantee to finish punching, blanking, the operation more than at least three roads such as stretching repeatedly on a crank press, can replace existing two crank presses with a double-crank forcing press, has reduced equipment cost.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of double-crank forcing press of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the horizontal bent axle 2 in the below of the fuselage 1 of double-crank forcing press of the present utility model, connecting rod 3 are the identical double link of structure, and the one end is hinged with the double-crank 21 of bent axle 2 respectively, and the other end is hinged with slide block 4 respectively; Slide block 4 is positioned at connecting rod 3 tops, and working plate 6 is positioned at the below of slide block 4; Flywheel 7 is positioned at the outside of fuselage 1 below, is connected with an end of bent axle 2 by clutch; The length of slide block 4 and working plate 6 can be held six punching press stations at least.The guide pillar 51 of ball guider 5 is fixed on by interference fit on four jiaos of lower platform 11 of fuselage 1, and guide pin bushing 52 is fixed in four angles of slide block 4 by interference fit; Because guide pin bushing 52 is a ball bearing guide bushing, during punching press, guide pillar 51 is rolling friction with the activity friction of guide pin bushing 52, and is very little to the wearing and tearing of guide pillar 51, prolonged the service life of guide pillar 51, and the cooperation of guide pillar 51 and guide pin bushing 52 is the matched in clearance in less gap.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
