Description

Semi-automatic cap clamping device for magnesium rod

Technical Field

The utility model belongs to the technical field of magnesium stick processing equipment, concretely relates to semi-automatic card cap device for magnesium stick.

Background

In the prior art, after the magnesium rod is manufactured and molded, a steel cap is required to be installed at one end of the magnesium rod according to different requirements of customers, and as the steel cap is clamped at one end of the magnesium rod, a fixed point needs to be punched on the steel cap manually for firm fixed connection after clamping.

The traditional method is that a hammer and a fillet nail are manually held, and the side edge of a steel cap is knocked, so that the steel cap is sunken in the side wall of a magnesium rod, and the steel cap is firmly connected with the magnesium rod; but the position relation of the knocking points and the knocking strength have great influence on the product quality. The fixed points are unevenly distributed due to the fact that the knocking points are not evenly distributed, the falling-off result is caused due to the fact that stress is not uniform, and the appearance is not attractive; the uneven knocking force can cause different sunken degrees, the steel cap can be damaged by penetrating with large force, and the connection is not firm with small force.

Therefore, the traditional operation mode is quite backward, the efficiency is difficult to be improved qualitatively, the manual operation standard degree is different, the bad part rate is high, and the cost of influencing the product is difficult to reduce.

an annular inner cavity is reserved between the circular outer sleeve and the central pillar, and a telescopic inner pipe which is connected with the annular inner cavity in a sliding manner is arranged in the annular inner cavity; the inner diameter of the front end of the telescopic inner pipe is provided with a conical inner cavity which corresponds to the invagination groove, and the inner diameter of the conical inner cavity is gradually reduced from the outer end surface to the inside; the inner diameter of the conical inner cavity is correspondingly attached to the outward end of the firing pin;

the rear end of the telescopic inner pipe is connected with a telescopic arm of the oil cylinder through a connecting piece; and the oil cylinder is communicated with a pump station on the operating platform.

In order to facilitate stable sliding connection, the round outer sleeve is fixedly connected with the central pillar through the connecting rib at the rear end, and the telescopic inner tube is in sliding insertion connection with the connecting rib through the spline groove at the rear end.

The utility model has reasonable structure design and convenient use, the telescopic inner tube can transversely reciprocate under the action of the oil cylinder, the conical inner cavity can press the firing pin to press down in the firing pin hole when moving, the steel cap inserted into the invagination groove is pressed by the end surface with the shape of a circular horn, and then the steel cap and the magnesium rod are firmly connected; the whole process only needs the manual work to load the magnesium stick can, the firing pin evenly presses the hole respectively and equally divides neatly each other, and the dynamics of oppression is unified, and the quality of product obtains abundant guarantee. The utility model provides a prior art have the inconvenient and non-uniform technical problem of standard of manual operation.

Fig. 2 is a schematic view of a changed state of fig. 1.

Fig. 3 is a schematic view of the matching state of the telescopic inner tube and the striker in the present invention.

In the figure, the device comprises a working table 1, an operating platform 2, a pump station 3, an oil cylinder 4, a connecting piece 5, a telescopic inner pipe 6, a circular outer sleeve 7, a central support column 8, a firing pin 9, an invagination groove 10, a spring 11 and a firing pin hole.

Detailed Description

Referring to fig. 1 to 3, the present invention includes an operation table 1;

a circular outer sleeve 6 which is transversely arranged is fixedly arranged on the operating platform 1; a central pillar 7 which is coaxial with the circular outer sleeve 6 is fixedly arranged in the circular outer sleeve 6, and an inward concave groove 9 is arranged at the center of the outer side end face of the central pillar 7; a plurality of striker holes 11 are formed in the outer diameter of the sunken groove 9, and the striker holes 11 correspond to the sunken groove 9 in an axial right-angle manner; the striker holes 11 are internally provided with the strikers 8 respectively, and the strikers 8 are elastically and telescopically connected with a step boss in the striker hole 11 through a spring 10; the opposite ends of the firing pin 8 are respectively in a round angle shape and are respectively flush and corresponding to the inner diameter of the inward concave groove 9; the outward ends of the firing pins 8 respectively protrude out of the outer diameter of the central pillar 7;
