Abstract

A fin forming machine, consisting of a main machine base, a main axle, an upper working bench, and a lower working bench. Wherein the two ends of the main axle are fixed on the inner wall of the main machine base, the lower working bench and the upper working bench are orderly connected above the upper part of the main machine base, and supporting columns are respectively connected under the upper working bench and the lower working bench; an upper die is fixed under the upper working bench, a lower die is fixed above a connecting rod, and the lower die is arranged above the lower working bench. The fin forming machine is characterized in that three cams are sleeved on the main axle, the cams at the two ends of the main axle drive the supporting columns to make vertical and reciprocal motion, and the middle cam drives the connecting rod to make horizontal reciprocal motion.

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

Heat exchanger is widely used in every field, and thermofin is the key element of the heat exchanger of various types.The fin make-up machine is the main process equipment of thermofin, the connecting rod of present fin make-up machine, the lower end reach through hole of pillar, main shaft passes through hole, rotate by the motor-driven main shaft, make connecting rod, pillar shape according to its lower end through hole, reciprocating, finish each steps such as charging, punching press, discharging.But, the existing fin make-up machine part that comes with some shortcomings.Main shaft contacts with connecting rod, pillar through-hole wall, mechanical wear is big, has influenced the life-span of main shaft, connecting rod, pillar, has increased the maintenance rate and the maintenance cost of equipment, has also reduced the precision of processing fin.In addition, guide pillar of the prior art moves up and down, and also can wear and tear in the contact position of itself and lower table, needs apply oil, and the general at present hand oiling that adopts, not only efficient is low, and oiling is inhomogeneous.So, 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 this utility model provides a kind of fin make-up machine, and it has solved the technical problem that the prior art wearing and tearing are big, the life-span is short.

For solving the problems of the technologies described above, technical solution adopted in the utility model: a kind of fin make-up machine, comprise main engine bed, main shaft, upper table, lower table, the main shaft two ends are due to the main engine bed inwall, the main engine bed top connects lower table, upper table successively by guide pillar, each connecting struts of upper and lower workbench below; Patrix is fixed in the upper table below, and counterdie is fixed in the connecting rod top, and counterdie is in the lower table top, sheathed three cams of main shaft, and cams at two ends drives pillar and is in vertical reciprocating motion, and the intermediate cam drive link is made horizontal reciprocating movement.

Described fin make-up machine, guide pillar is provided with oil through vertically, and guide pillar and upper and lower workbench contact position are provided with cross through hole.

Described fin make-up machine, top pressure spring between connecting rod lower end and pad.

The utility model is finished the process of fin by the up-and-down movement that the cam cylindrical comes the horizontal reciprocating movement and the pillar of drive link, and mechanical wear is little, the life-span is long, has reduced maintenance rate and maintenance cost; Moreover, oil through is set on the guide pillar, oil through links to each other with the oil hydraulic system of outside, when the up-and-down movement of workbench, automatically oil is injected the guide pillar outer wall, make lubricated not easy to wear because of oil of contacting between guide pillar and workbench, both reduced wearing and tearing between the two, overcome the shortcoming that available technology adopting is manually rinsed oil again, improved efficient.

The specific embodiment

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

As shown in Figure 1, 2, 3, the two ends of main shaft 3 respectively connect a bearing 1, and the two ends of main shaft 3 are due to the inwall of main engine bed 5.Be connected by key between outer sheathed three cams of main shaft 3, main shaft 3 and cam.10 on main engine bed 5 and top board are fixedlyed connected by guide pillar 16, are followed successively by upper table 9, lower table 7 between the two, and upper table 9, lower table 7 can slide relatively with 16 of guide pillars, and spring 11 is placed in outside the guide pillar 16 between lower table.The below of upper table 9, lower table 7 respectively is connected with

pillar

8,28, the pillar 8 lower ends rocking bar 17 that is rotationally connected, and rocking bar 17 is rotationally connected with bearing 16, and the other end of rocking bar 17 is established a bearing 18, and bearing 18 contacts with the rolling of cam 13C cylindrical.The lower end of pillar 28 rocking bar on the bearing 2 that is rotationally connected, the other end of rocking bar also rolls with cam 13C cylindrical and contacts.The annexation of cam 13A is the same with cam 13C.

Lower table 7 is provided with slideway, and slideway is provided with needle roller 14, and counterdie 15 is made horizontal reciprocating movement in the slideway of lower table 7, and counterdie 15 constitutes a secondary mould with the patrix 12 that is installed on upper table 9.Counterdie 15 belows are connected with a connecting rod 4, and the lower end of connecting rod 4 is connected with a slide block 22, and slide block 22 can horizontally slip, and slide block 22 is circular groove, and this groove matches with cam 13B cylindrical, and slide block 22 is a bearing with cam 13B contact position.Connecting rod 4 lower ends are also by nut 20 roof pressure pads 19 and spring 21.

Establish a vertical oil through 26 in the middle of the guide pillar 16, oil through 26 is connected with the oil hydraulic system of outside, and guide pillar 16 also is provided with horizontal oil through 27, and oil through 27 is connected with oil through 26, so that oil flows into the contact position of guide pillar 16 and upper and
