A slider rack is arranged inside the main engine seat, a slider is arranged above the main engine seat, the slider is of a circular groove shape, and the circular groove is matched with a cam excircle. A sliding channel is arranged on the slider rack, bearings are respectively arranged at the upper and lower portion of the sliding channel, a rod-shaped part extend out from two ends of the slider and is inserted into the sliding channel on the slider, the center of the slider is provided with a rocker hole, a rocker is inserted into the rocker hole. Dynamic connection and matching of the rocker and the slider is used, so that stability of a motion process of a demolding slider is achieved, fit precision of upper and lower molds is ensured. Therefore, molded phenomenon does not appear in the process of manufacturing fins, and machining precision is ensured.

Description

A kind of fin make-up machine

Technical field

The utility model belongs to thermofin process equipment manufacturing technology field, particularly a kind of fin make-up machine.

Background technology

The fin make-up machine is the main process equipment of thermofin.This equipment all is to be rotated by the motor-driven main shaft usually; Make rotatablely moving on the main shaft change the rectilinear motion of connecting rod, pillar into through toggle; Thereby the mould on the drive workbench is done punching press action, realizes each steps such as charging, punching press, discharging to rapidoprint.The wherein realization of the demoulding discharging of fin is through the realization that moves horizontally of a direct-connected connecting rod of toggle.In the prior art, connecting rod is connected on the slide block that can horizontally slip, and slide block is circular groove, and this groove matches with the cam cylindrical.Yet the motion process of connecting rod is to make the process of vacillating now to the left, now to the right by central pivot point, and the top of connecting rod is a circular motion in fact, causes the unstability of slide block movement therefrom.And have influence on the precision of mould side-to-side movement thus, the error that causes cooperating between the upper and lower mould and the generation of damaged phenomenon.Therefore be necessary the structure of existing fin make-up machine is improved and innovated, to overcome the above-mentioned defective that exists.

Summary of the invention

The purpose of the utility model provides a kind of fin make-up machine, through changing mould annexation between connecting rod and cam, realizes improving the technical problem of mould quality of fit up and down.

For solving the problems of the technologies described above the technical scheme that the utility model is taked: a kind of fin make-up machine comprises main engine bed, main shaft, upper table, lower table; The main shaft two ends are due to the main engine bed inwall, and the main engine bed top connects lower table, upper table successively through guide pillar, and upper and lower workbench below respectively connects connecting rod; Lower table is laid the mould pedestal, establishes upper and lower working plate driving cam A, B and a slide plate driving cam on the main shaft, and wherein working plate driving cam A, B are located at the two ends of main shaft; The slide plate driving cam is installed on the centre of main shaft, and the upper wall of main engine bed is established the rocking arm pole socket, and rocking lever is installed on it; Die frame links together through the cam of rocking lever and main shaft, it is characterized in that: on the internal backplane of main engine bed, be provided with slider frame, it is provided with slide block; Slide block is circular groove, and this groove matches with the cam cylindrical, establishes slideway on the slider frame; Slideway is respectively equipped with bearing up and down, and the two ends of slide block have shaft-like outstanding, assign in the slideway on slider frame; The central authorities of slide block are the rocking lever hole, and rocking lever is assigned in the rocking lever hole.

Described rocking lever top is provided with bearing, is slidingly connected through bearing and rocking lever hole.

Described slide block and rocking lever junction also are provided with the microspur adjustment screw rod of symmetry, and screw rod is provided with holddown spring.

The utility model dynamically is connected cooperation through what utilize rocking lever and slide block; Realized the stability of the motion process of demoulding slide plate; Thereby guaranteed the quality of fit of mould up and down, therefore guaranteed the molding phenomenon can not occur in the fin processing, guaranteed machining accuracy.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the slide block structure sketch map of the utility model;

Fig. 3 is the slider frame structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

Like Fig. 1,2, shown in 3, the two ends of main shaft respectively connect a bearing, and the two ends of main shaft are due to the inwall of main engine bed 1.Pack into successively respectively on the main shaft upper and lower working plate driving cam A, B and a slide plate driving cam 10, and through key each cam and main shaft are fixed, cam is distributed in main two ends, and slide plate driving cam 10 is installed on the central authorities of main shaft.Establish two guide pillars on main engine bed 1 table top, guide pillar is followed successively by upper table, lower table from top to bottom, can slide relatively between upper table, lower table and guide pillar.

Respectively establish two bearing blocks about the below of upper table, lower table, installing connecting rods on it, the lower end of connecting rod is rotatably connected on cam A, B is last.

Lower table is provided with slideway, and counterdie is made horizontal reciprocating movement in the slideway of lower table, and counterdie constitutes a secondary mould with the patrix that is installed on upper table.The counterdie below is connected with a rocking lever 7, and rocking lever 7 is installed on the rocking arm pedestal 6 on the main engine bed base plate, and the lower end of rocking lever 7 contacts with slide plate driving cam 10.

On the inner bottom plating of main engine bed 1, be provided with slider frame 2, it is provided with slide block 9, and slide block 9 is circular groove with slide plate driving cam 10 contact-making surfaces; This groove matches with slide plate driving cam 10 cylindricals, establishes slideway 13 on the slider frame 2, and slideway is respectively equipped with bearing 11 up and down; The two ends of slide block 9 have shaft-like outstanding 3; Assign in the slideway 13 on slider frame 2, the central authorities of slide block 2 are rocking lever hole 12, and rocking lever 7 is assigned in rocking lever hole 12.

Rocking lever 7 tops are provided with bearing 5, are slidingly connected through bearing 5 and rocking lever hole 12, alleviate the resistance to sliding of rocking lever 7 in rocking lever hole 12 with this.

Slide block 9 is adjusted screw rod 4 with the microspur that rocking lever 7 junctions also are provided with symmetry, and screw rod 4 is provided with holddown spring 8.Through the adjustment screw, realize that rocking lever 7 waves the inching of distance.
