Abstract
The utility model relates to the technical field of manufacturing of pressing machines, and aims at providing a novel connecting rod structure of the pressing machine for solving the technical problem that the anti-deviated load capability of a sliding block in the existing pressing machine is weakened. The novel connecting rod structure of the pressing machine comprises an eccentric shaft and a connecting rod sheathed on the eccentric shaft, wherein the connecting rod and a lifting screw rod are connected through a pin, and a pressure-bearing tile is arranged between the connecting rod and the lifting screw rod. The novel connecting rod structure of the pressing machine is characterized in that a cylindrical surface is arranged at the connecting end of the connecting rod and the lifting screw rod, a cylindrical surface groove is arranged at the top end of the lifting screw rod, and the cylindrical surface connecting end of the connecting rod extends into the cylindrical surface groove at the top end of the lifting screw rod for connection through the pin. By adopting the novel connecting rod structure of the pressing machine, the rigidity of the pressing machine and the anti-deviated load capability of the sliding block are greatly enhanced.
Description
Technical field
The utility model relates to pressure mechanism technology for making field.
Background technology
The tradition forcing press mostly is bent axle bulb formula, be that bent axle connects connecting rod, connecting rod links to each other by screw thread pair with lifting screw, the end of lifting screw is spherical, be installed on the ball cup in the slide block, the bulb of lifting screw can 360 ° of rotations in ball cup, and the technical problem of bringing thus is: the anti-bias load ability of slide block weakens.
Summary of the invention
It is strong that the purpose of this utility model provides a kind of anti-bias load ability, and the press connecting rod structure that lathe rigidity strengthens is to solve the technical problem that slide block anti-bias load ability that present forcing press exists weakens.
Do not reach above-mentioned technical purpose, the technical solution adopted in the utility model is: the novel press machine connection rod structure, comprise eccentric shaft, be set in the connecting rod on the eccentric shaft, connecting rod and lifting screw adopt pin to be connected, and are provided with pressure-bearing watt between connecting rod and lifting screw, and it is characterized in that: the link of described connecting rod and lifting screw is a cylinder, the top of lifting screw is the cylinder groove, and the interior pin that adopts of cylinder groove that the cylinder link of connecting rod stretches into the lifting screw top connects.
The beneficial effects of the utility model: adopt eccentric shaft to replace bent axle, the stressed diameter of axle increases, and makes the rigidity of forcing press strengthen; Connecting rod adopts cylinder to be connected with lifting screw, and the rotation that is connected 360 ° by traditional bulb changes the 180 ° of rotations in front and back into, thereby has strengthened the anti-bias load ability of slide block.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1, eccentric shaft, 2, connecting rod, 3, pin, 4, pressure-bearing watt, 5, nut, 6, lifting screw, 7, slide block, 8, the cylinder termination.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in drawings, forcing press is provided with slide block 7, is provided with the envelope height that lifting screw 6 is used to adjust slide block 7 in the inside of slide block 7, and the outside of lifting screw 6 is provided with nut 5, drives the adjustment of lifting screw 6 by the rotation of nut 5.
As shown in drawings, the utility model adopts eccentric shaft 1 to replace traditional crankshaft structure, suit connecting rod 2 on the eccentric shaft 1.
As shown in drawings, connecting rod 2 and lifting screw 6 adopts pins 3 to be connected, and is provided with pressure-bearing watts 4 between connecting rod 2 and lifting screw 6, by pressure-bearing watt 4 transmitted loads.
As shown in drawings, connecting rod 2 is cylinder termination 8 with the link of lifting screw 6, this cylinder termination 8 extend in the cylinder groove on lifting screw 6 tops, can rotate front and back in the cylinder groove of lifting screw this cylinder termination 8, but about can't rotate, connect 360 ° of rotations and cause the weak technical problem of slide block unbalance loading ability thereby overcome traditional bulb.
This utility model substitutes bent axle with eccentric shaft, and the connecting rod of cylindrical structure substitutes bulb formula connecting rod, and during impulse stroke, the cylinder contact by pressure-bearing watt transmitted load, during backhaul, is born the weight and the withdrawing pattern power of slide block by pin.Compare with traditional structure, the rigidity of lathe and slide block anti-bias load ability improve greatly.
