Abstract

The utility model discloses an improved structure of a vertical crank press. The improved structure comprises a base, a support pillar, a press body, a motor, a spindle, a crankshaft, a connecting rod, a sliding block, a one-way wrench and a lifting screw rod, wherein the support pillar is erected on the base, and supports the press body; the spindle penetrates through the press body; the motor is arranged on the press body, and is connected with the spindle; the sliding block is arranged at the front end of the press body in a sliding way; a flywheel is arranged on a rear part; one end of the crankshaft is connected with the flywheel on the spindle, and the other end of the crankshaft is connected with the sliding block through the connecting rod; bearings are sleeved between the spindle and the press body and between the crankshaft and the connecting rod respectively, and are ball bearings; the press body can be adjusted vertically on the support pillar. The improved structure has the advantages that: due to the adoption of the ball bearings, lubricating oil is not required to be frequently added in the using process of the ball bearings, namely the ball bearings can be maintenance-free, the press is not required to be stopped to maintain the bearings, the production efficiency of the press is improved, and the maintenance probability of the press is lowered; the improved structure is widely adaptable; and a closed height can be greatly changed by adjusting the press body vertically.

Description

A kind of structure-improved of vertical crank press

Technical field:

The utility model relates to a kind of structure-improved of vertical crank press.

Background technology:

Practise it, middle-size and small-size vertical crank press is to utilize driven by motor main shaft and bent axle to rotate, and bent axle drives slide block through connecting rod simultaneously and moves up and down; Change into vertical up-or-down movement thereby realizing to rotatablely move, make the mould that is installed in slider bottom do the punching press action, rotate very swimmingly in order to make main shaft and bent axle; Be provided with bearing between main shaft and the body and between bent axle and the connecting rod, and traditional forcing press all is to use sliding bearing, the every certain interval of time of the instructions for use of sliding bearing; Just must shut down; Add lubricating oil to bearing, this has a strong impact on production efficiency, and the maintenance of machinery equipment is also more loaded down with trivial details.

Summary of the invention:

The purpose of the utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of bearing of exempting from often to safeguard to be provided, do not influence the vertical crank press that production is normally carried out, but body adopts the dual-gripper post to support the body up-down adjustment.

The goal of the invention of the utility model can realize through following technical scheme: a kind of structure-improved of vertical crank press, include base, support column, body, motor, main shaft, bent axle, connecting rod, slide block, unidirectional wrench and lifting screw, and support column stands on the base and props up body; Main shaft passes body, and motor is located at the body top and is connected with main shaft, and the slide block cunning is assigned in the body front end; Flywheel in the wings; Flywheel is connected on bent axle one end and the main shaft, and the other end is connected with slide block through connecting rod, is socketed with bearing between main shaft and the body and between bent axle and the connecting rod; This bearing is a ball bearing, and body can be made up-down adjustment on support column.

Compared with prior art; The utlity model has following beneficial effect: after having adopted ball bearing; Because the ball bearing use does not need often to add lubricating oil, can be non-maintaining, this safeguards bearing with regard to not shutting down; Improve the production efficiency of forcing press, reduce the machine maintenance probability.Wide adaptability can change closed height significantly through the body up-down adjustment.

Description of drawings:

Fig. 1 is the structure chart of the vertical crank press of the utility model.

The specific embodiment:

Below in conjunction with accompanying drawing this utility patent is described further.

The vertical crank press of present embodiment includes base 1, support column 2, body 3, motor 4, main shaft 5, bent axle 6, connecting rod 7 and slide block 8, unidirectional wrench 10, lifting screw 11; Support column 2 stands on the base 1 and props up body 3, and main shaft 5 passes body 3, and motor 4 is located at body 3 tops and is connected with main shaft 5; Slide block 8 sliding body 3 front ends that are assigned in; Flywheel in the wings, flywheel is connected on bent axle 6 one ends and the main shaft 5, the other end is connected with slide block 8 through connecting rod 7; Be socketed with bearing 9 between main shaft 5 and the body 3 and between bent axle 6 and the connecting rod 7, this bearing 9 is a ball bearing.Base 1 and body 3 be apart from scalable, rotates lifting screws 11 through the unidirectional wrench 10 that can change direction and reach and regulate body and base apart from change, the adaptation processing request.Body 3 rotates lifting screw 11 by the unidirectional wrench 10 that dual-gripper post 2 supports through changing direction, can change the closed height of body 3 significantly.

Going up the above, only is the preferred embodiment of the utility model, is not that the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technical scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.

Claims

1. the structure-improved of a vertical crank press includes base, support column, body, motor, main shaft, bent axle, connecting rod, slide block, unidirectional wrench and lifting screw, and support column stands on the base and props up body; Main shaft passes body, and motor is located at the body top and is connected with main shaft, and the slide block cunning is assigned in the body front end; Flywheel in the wings; Flywheel is connected on bent axle one end and the main shaft, and the other end is connected with slide block through connecting rod, it is characterized in that: be socketed with bearing between main shaft and the body and between bent axle and the connecting rod; This bearing is a ball bearing, and body can be made up-down adjustment on support column.
