Problems solved by technology

The current transmission mechanism is driven by hydraulic transmission. Due to its hydraulic transmission structure, the precision is difficult to control, especially the change of oil temperature causes the transmission precision to drop, and the size of the molded product is difficult to control. At the same time, a large hydraulic station is required to work, and the production efficiency is low.
Therefore, the traditional mechanism currently used has defects such as complex structure and low precision. Not only the transmission mechanism is easily damaged, maintenance is difficult, but also the quality of the product is affected.

Embodiment Construction

[0009] The present invention is the transmission device of the upper slider pressure mechanism 11 of the molding machine, which is responsible for transmitting the motion requirements and power requirements to the upper slider pressure mechanism 11, and decelerates the high-speed rotational motion of the motor 1 to the molding working speed of the molding machine through the reducer 2. Drive the eccentric mechanism that is made of eccentric wheel 4 and eccentric connecting rod 5 to rotate through transmission shaft 3, and then drive intermediate power transmission toggle lever 6 around the fulcrum by eccentric connecting rod 5. 1 Reciprocating swing up and down, the middle force transmission toggle 6 drives the crank linkage mechanism composed of cranks 9, 10 and connecting rod 8 through the vertical power toggle linkage 7, and finally the crank linkage mechanism drives the upper slider pressure mechanism 11 to reciprocate in a straight line up and down. sports.

Abstract

The invention discloses a transmission mechanism for a pressure mechanism of an upper slide block of a forming machine, and relates to a transmission mechanism. The transmission mechanism comprises a decelerator driven by a motor; the decelerator is connected with an eccentric mechanism consisting of an eccentric wheel and an eccentric connecting rod through a transmission shaft; the eccentric connecting rod drives a middle force transfer toggle rod to swing vertically; the middle force transfer toggle rod drives a crank-link mechanism through a vertical power toggle rod; and the crank-link mechanism drives the pressure mechanism of the upper slide block to perform vertical reciprocating linear motion. The transmission mechanism mainly adopts a toggle transmission mechanism to carry out transmission, and realizes the transmission of motion and power through a series of rotary motion and swing; and because the rotary motion has the characteristics of simple transmission, precise transmission and little energy loss, the transmission mechanism can fully meet the motion and power requirements of the upper slide block.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a transmission mechanism of a sliding block pressure mechanism on a molding machine. Background technique [0002] The upper slider of the forming machine is responsible for the pressing work, which requires accurate motion requirements and power requirements, and the guarantee of its motion requirements and power requirements is mainly realized by the transmission mechanism. The current transmission mechanism is driven by hydraulic transmission. Due to its hydraulic transmission structure, the precision is difficult to control, especially the change of oil temperature causes the transmission precision to drop, and the size of the molded product is difficult to control. At the same time, a large hydraulic station is required to work, and the production efficiency is low. . Therefore, the traditional mechanism currently used has defects such as complex structure and low precision. Not ...
