Description

Punch structure integrating punching and stamping of test paper

Technical Field

The utility model relates to a machinery punching press mechanism equipment technical field, concretely relates to test paper punches drift structure of punching press as an organic whole.

Background

The liquid viewing mirror is used in liquid pipeline of refrigerating and air conditioning equipment to indicate the flow state of refrigerant, the water content in refrigerant and the flow state of lubricating oil in oil returning pipeline of oil separator. The sight glass is provided with a wetness indicator to indicate the amount of water in the refrigerant by changing color. The test paper perforating device is applied to perforating and punching test paper in the humidity indicator. In current production, the punching and stamping processes are separated into two steps. The test paper of the small wafer needs to be punched on the whole test paper, then the test paper is sent to the next step, and the punched test paper needs to be selected and punched on the test paper seat. This process is time consuming and labor intensive and has low efficiency.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of village among the prior art, the utility model provides a test paper punching and stamping punch structure as an organic whole that structural design is reasonable.

The technical scheme of the utility model as follows:

the utility model provides a test paper punching and punching drift structure as an organic whole, a serial communication port, including outside base, outside base inside is equipped with outer drift main part, the inside interior drift main part that is equipped with of outer drift main part, outer drift main part outer wall cover is equipped with outside spring, interior drift main part outer wall cover is equipped with inside spring, the fixed drift that punches that sets up in the outer drift main part, the fixed punching press drift that sets up in the interior drift main part, the drift cover that punches is established in the punching press drift outside, and can relative motion between drift and the punching press drift of punching.

The punch structure integrating punching and stamping of the test paper is characterized in that an inner punch top block is arranged at the top of the inner punch main body, and a contact head is fixedly arranged on the inner punch top block.

The punch structure integrating punching and stamping of the test paper is characterized in that outer punch jacking blocks are arranged at the positions, located on the two sides of the inner punch main body, of the top of the outer punch main body, and contact heads are fixedly arranged on the outer punch jacking blocks.

The punch structure integrating punching and stamping of the test paper is characterized in that a clamp spring used for limiting the movement of the inner punch body in the outer punch body is arranged on the inner punch body.

The utility model has the advantages that: through setting up drift and the punching press drift of punching, and punch drift and punching press drift can independent motion to can realize punching the integration of punching the punching press to the test paper, save a large amount of process time, also save a large amount of manufacturing cost.

Drawings

Fig. 1 is a schematic view of the overall three-dimensional structure of the present invention;

FIG. 2 is a schematic view of the overall internal structure of the present invention;

in the figure: 1-contact head, 2-top of inner punch, 3-main body of inner punch, 4-inner spring, 5-punching punch, 6-main body of outer punch, 7-punching punch, 8-outer base, 9-top of outer punch, 10-snap spring, 11-cylindrical pin, 12-outer spring.

Detailed Description

The invention is further described with reference to the accompanying drawings.

Example (b):

as shown in fig. 1-2, a punch structure for punching and pressing test paper into a whole includes a contact 1, an inner punch top 2, an inner punch body 3, an inner spring 4, a punching punch 5, an outer punch body 6, a punching punch 7, an outer base 8, an outer punch top 9, a snap spring 10, a cylindrical pin 11, and an outer spring 12.

The inner punch structure comprises a punching punch 5, an inner punch body 3, an inner punch top block 2 and a contact head 1; the contact head 1 is fixed on the inner punch top block 2 in a threaded manner, and the contact head 1 can be connected with a cam or other pressing mechanism, such as an air cylinder, so as to realize the punching action. The inner punch top block 2 is fixed on the inner punch body 3 in a threaded manner, and the punching punch 5 is welded below the inner punch body 3 and penetrates through the inner punch body 3 and the external base 8.

The outer punch structure comprises a punching punch 7, an outer punch body 6, an outer punch top 9, a cylindrical pin 11 and a contact head 1. Contact 1 spiro union is fixed on outer drift kicking block 9, and outer drift kicking block 9 passes through cylindric lock 11 and fix with screw on outer drift main part 6, and the welding of drift 7 that punches is at the lower extreme of outer drift main part 6, and the drift 7 that punches wears to establish on external base 8, and jump ring 10 is equipped with to the inside of outer drift main part 6, can play the spacing effect of 3 movements of interior drift main part, avoids punching press drift 5 to surpass spacingly.

The inside blind hole that is equipped with of outer drift main part 6, inside spring 4 and interior drift main part 3 all set up inside outer drift main part 6, and inside spring 4 cover establish including on 3 outer walls of drift main part, be equipped with step-like blind hole in the outside base 8, outside drift main part 6 and outside spring 12 all set up inside outside base 8, and outside spring housing 12 establishes on 6 outer walls of outer drift main part.

When punching, the external pressing mechanism is contacted with the 3 contact heads 1 and synchronously presses downwards with the inner punch body 3 and the outer punch body 6. At the moment, the outer spring 12 is compressed, the inner spring 4 is basically not compressed, and the punching punch 5 does not extend out of the punching punch 7, so that the punching function is realized; when pushing down to the certain degree, outside spring 12 reaches the compression limit, and outer drift main part no longer moves down, and outside pushing down mechanism drives interior drift main part 3 and continues to push down this moment, and inside spring 4 compresses for punching press drift 5 stretches out punching press drift 7, and tightly presses the test paper seat of below with the test paper of beating down, realizes the function of punching press.
