Description

Crank press with pressure alarming function

Technical Field

The invention belongs to the technical field of crank presses, and particularly relates to a crank press with a pressure alarm function.

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 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 have no pressure alarm function, and the workpieces, the dies and the presses are damaged when the pressing force of the pressing device is too large.

Disclosure of Invention

The invention aims to solve the defects of the prior art, and provides a crank press with a pressure alarm function, which comprises a crank press, wherein the crank press comprises a pressure base, a press frame, a pressing mechanism and a driving mechanism, the pressure base comprises a base frame, a tool table top and a pressure sensing device, the pressure sensing device is arranged below the tool table top, a tool platform is arranged in the base frame, and the pressure base is arranged in the center of the bottom of the press frame.

Further, the press base is shaped as a rectangular cube with two sides mounted to the sides of the press frame and aligned with the press frame side posts and a bottom aligned with the press frame bottom and resting on the ground at the center of the press frame.

Furthermore, the shape of the tooling table-board is a rectangular table-board, and the tooling table-board is arranged at the center of the top of the base frame.

Furthermore, the pressure sensing device is arranged below the table surface of the tool, and the pressure sensing device is connected to an external operation panel.

Furthermore, the surface of the tooling table surface is provided with a fixture fixing groove.

Has the advantages that:

compared with the prior art, the invention has reasonable structural design, stable work and good stamping effect by adopting the double-crank mechanism to control the pressing action; and a pressure sensor is arranged below the table surface of the tool to realize pressure detection and alarm.

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 crank press with pressure alarming function, includes the crank press, the crank press by pressure base, press frame, push down mechanism and actuating mechanism and constitute, pressure base constitute by base frame, frock mesa and forced induction device, forced induction device install in frock mesa below, frock platform install inside the base frame, pressure base install at press frame bottom center.

As shown in figures 1, 2 and 3, the crank press with pressure alarm comprises a pressure sensor, a pressure alarm and a pressure alarm controller;

a press frame: the device is composed of a rectangular pressure 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 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 crank mechanism rotates through the crankshaft, the connecting rod of the crank mechanism makes up-and-down reciprocating motion, the connecting rod is connected with the lower pressing block, the lower pressing block makes 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, the processing die at one end is installed on the tooling table surface on the pressure base, the processing die at the other end is installed below the lower pressing block, when the lower pressing block presses downwards, the die is superposed to perform stamping, the lower pressure can be applied to the tooling table surface, when the pressure applied to the tooling table surface is too high, the threshold value of a pressure sensing device below can be triggered, and meanwhile, an alarm is given out by an operation panel on the outer side.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
