If a set of stamping dies is used, after stamping one side, it is necessary to turn over the other side, and then stamp the other side again, which reduces the punching efficiency, and the holes on both sides punched by a set of stamping dies The number and position are the same, so it is impossible to punch square tubes with different numbers and positions of punching holes on both sides; if two sets of stamping dies are used, the cost of the die will be increased, and the cost of manpower and machine costs will be increased

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0022] Such as figure 1 , figure 2 with image 3 As shown, the square tube double-sided flushing mechanism of the present invention includes an upper mold plate 1 and a lower mold plate 2 which are arranged opposite to each other.
[0023] The lower surface of the upper template 1 is elastically connected to an upper binder plate 3, and the upper binder plate 3 is provided with an upper punch 5, and the lower end 51 of the upper punch 5 protrudes from the upper binder plate 3 toward the lower template 2 . Wherein, the upper mold plate 1 and the upper binder plate 3 are connected by a compression spring 7, and the spring 7 may be a rectangular spring.
[0024] The lower die plate 2 is provi...

The invention discloses a counter punching mechanism for processing both sides of a square tube, which comprises an upper die plate and a lower die plate arranged oppositely. One surface of the upper die plate facing the lower die plate is elastically connected with an upper pressing plate, an upper punch is disposed inside the upper pressing plate, the lower end of the upper punch facing the lower die plate is protruded from the upper pressing plate, a lower pressing plate is arranged on one surface of the lower die plate facing the upper die plate, a lower punch is disposed inside the lower pressing plate, the upper end of the lower punch facing the upper die plate is protruded from the lower pressing plate, a square tube required to be punched is disposed in a space reserved between the upper pressing plate and the lower pressing plate, and a female core can be held in the square tube. Two opposite sides of the square tube can be punched with holes by the counter punching mechanism so that mould cost is saved. Since both sides are punched simultaneously, procedures are saved, and punching efficiency is increased. Besides, the number and position of the upper punch and the lower punch can be set according to quantity and position of holes required to be punched on the square tube, and accordingly the counter punching mechanism for processing both sides of the square tube has higher flexibility and universality.
Description
technical field [0001] The invention relates to a stamping die, in particular to a square tube double-face punching mechanism. Background technique [0002] In the prior art, when punching is required on two opposite surfaces of the square tube, usually two processes are required, one punching is performed for each surface, and the punching efficiency is low. If a set of stamping dies is used, after stamping one side, it is necessary to turn over the other side, and then stamp the other side again, which reduces the punching efficiency, and the holes on both sides punched by a set of stamping dies The number and positions are the same, so it is impossible to punch square tubes with different punching numbers and positions on the two surfaces; if two sets of stamping dies are used, the cost of the die will be increased, and the labor cost and machine cost will be increased. Contents of the invention [0003] The technical problem to be solved by the present invention is to...
