Description

Mute type double-crank press

Technical Field

The invention belongs to the technical field of double-crank presses, and particularly relates to a mute type double-crank press.

Background

The press is a stamping press, and is often used for forming product parts by performing various stamping processes on plates by matching with a group of dies placed on the press, and is widely applied to stamping and forming of electronics, communication, electrical appliances, furniture, vehicles, hardware parts and the like. When the press machine works, the lower pressing block drives the upper die to move relative to the lower die, the rotary motion of the crank is converted into linear motion, and the motor drives the gears, the crank (or the eccentric gear), the connecting rod and the like to operate to convert the rotary motion into the up-and-down reciprocating motion of the sliding block, so that the stamping is realized. The press machine may be classified into a crank press machine, a link press machine, a toggle press machine, a friction press machine, a screw press machine, a rack press machine, a cam press machine, and the like according to a difference in driving mechanism.

The crank type press is most applied in actual production operation, has long stroke, uniform load borne by a punch press and easy manufacture of a crank mechanism, and is applied to punching, bending, stretching, forging and other almost all press processing. However, most of the existing double-crank type presses are directly connected with a motor and a gear, and the moving track is a common section bar, so that the work is influenced by large noise generated by the work of the gear and the track during working.

Disclosure of Invention

The invention aims to solve the defects of the prior art, and provides a mute type double-crank press which comprises a double-crank press, wherein the double-crank press comprises a press frame, a mute pressing mechanism and a driving mechanism, the mute pressing mechanism comprises a pressing block, mute rails and a hydraulic cylinder, two mute rails are arranged on two sides of the pressing block, the mute rails use embedded ceramic ball rails, and the hydraulic cylinder uses a mute hydraulic cylinder.

Furthermore, two silent rails are arranged on two sides of the lower pressing block, and the silent pressing mechanism is arranged in the middle of the frame of the press machine and is arranged in parallel with the base and the cross beam of the frame.

Furthermore, the silent rail uses embedded ceramic ball rails, which are installed between two side columns.

Furthermore, a mute hydraulic cylinder is used as the hydraulic cylinder, an output shaft of the mute hydraulic cylinder is connected with the lower pressing block, and a cylinder body of the hydraulic cylinder is connected with the cross beam.

Furthermore, the press frame is composed of a base, a column and a top beam.

Furthermore, I-shaped sliding rails are arranged at two ends of the side surface of the lower pressing block and are matched and connected with the mute sliding rails, so that the lower pressing block is arranged in parallel with the base and the top cross beam.

Has the advantages that:

compared with the prior art, the invention has reasonable structural design, adopts the double-crank mechanism to control the pressing action, has stable work and good stamping effect, and adopts the embedded ceramic ball guide rail and the mute hydraulic cylinder to ensure that the noise is reduced in the pressing process.

Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

Example (b):

the utility model provides a mute type double crank press, includes the double crank press, the double crank press by press frame, silence push down mechanism and actuating mechanism and constitute, silence push down mechanism constitute by briquetting, silence track and pneumatic cylinder down, two silence tracks of briquetting both sides installation down, the silence track use embedded ceramic ball track, the pneumatic cylinder use the silence pneumatic cylinder.

As shown in fig. 1, 2 and 3, the mute type double crank press comprises;

a press frame: the device is composed of a rectangular base 1, upright posts 2 erected at four corners of the base, a cross beam 3 crossing over the upright posts, and a mounting platform 6 arranged behind the cross beam.

Silence pushes down mechanism: the mute press-down mechanism is arranged between the cross beam 3 and the base 1, and the cross beam 3, the base 1 and the press-down block 5 are arranged in parallel.

A driving mechanism: comprises a driving motor, a driving belt wheel, a transmission mechanism and a double-crank mechanism

The double-crank mechanism 9: the crank mechanism is arranged at the horizontal position inside the cross beam, and the connecting rod in the crank mechanism is connected with the lower pressing block 5.

The transmission mechanism is as follows: the noise reduction device is composed of a driving shaft and a mute gear, wherein the driving shaft is connected with a driving belt wheel, and the mute gear is connected with the driving shaft and a crankshaft.

When the driving motor is started, the driving belt wheel is driven through the belt wheel, the driving belt wheel drives the mute gear through the driving shaft, the mute gear drives the crankshaft, the double-crank mechanism rotates to work through the crankshaft, the connecting rod of the double-crank mechanism makes up-and-down reciprocating motion, the connecting rod is connected with the lower pressing block, the lower pressing block is made to make up-and-down reciprocating motion through the mute track, when the lower pressing block moves, the output shaft of the mute hydraulic cylinder connected to the lower pressing block moves downwards simultaneously, and the working noise is reduced while the working stability of the lower pressing block is kept.
