[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1 to 4 The utility model provides a kind of technical scheme: a kind of upper and lower punch die with clamping, including general base 1, the top of general base 1 is fixed with support column 201, and the outer side of support column 201 is provided with external thread groove 202, the top of support column 201 is butted with two semicircle table shape limiting pieces 203, and the opposite side between two semicircle table shape limiting pieces 203 is butted with clamping piece 204, the inner side of clamping piece 204 is inserted with punch main body 205, and positioning base 206 is set between the outer side of two semicircle table shape limiting pieces 203;Through the cooperation between the support column 201 of general base 1 top, semicircle table shape limiting piece 203, clamping piece 204, punch main body 205 and positioning base 206, punch can be directly installed and replaced by the structure design of separation, so that the actual cost can be controlled to a certain extent, the mold manufacturing cycle can be shortened by the way of clamping, so as to reduce manufacturing cost, and the time of repair is saved, to improve actual production efficiency, the mode of disassembly and assembly is very convenient and fast, convenient for operator to operate, so as to effectively improve the practicability of upper and lower punch die.

[0025] As Figure 1 And Figure 2 It should be noted that positioning base 206 is hollow, and the inner diameter of positioning base 206 gradually decreases from bottom to top, the inner wall of positioning base 206 and the side opposite to two semicircle table shape limiting pieces 203 are mutually attached, and the outer side of semicircle table shape limiting piece 203 is inclined, specifically, the outer side of semicircle table shape limiting piece 203 is inclined to the side close to clamping piece 204 from bottom to top in sequence, so as to extrude two semicircle table shape limiting pieces 203 by the inner wall of positioning base 206, then extrude and limit clamping piece 204 by semicircle table shape limiting piece 203, realize the positioning work of punch main body 205.

[0026] Meanwhile, the inner side of the positioning base 206 is provided with an internal thread groove 207. The positioning base 206 is threadedly connected to the outer thread groove 202 on the outside of the support column 201 through the internal thread groove 207, so that the positioning base 206 can be properly threadedly connected to the outside of the support column 201.

[0027] In addition, the universal base 1 has two first clamping slots 301 on its outer side, and the positioning base 206 has two second clamping slots 302 on its outer side. The top and bottom of the first clamping slots 301 are open, and the two first clamping slots 301 are symmetrically distributed front and back. The top of the second clamping slots 302 is open, and the two second clamping slots 302 are symmetrically distributed front and back. The universal base 1 can be easily clamped through the two first clamping slots 301 with tools such as pliers, and the outer side of the positioning base 206 can also be easily clamped through the two second clamping slots 302, which facilitates rotation, disassembly or installation.

[0028] In addition, the clamping member 204 is composed of several clamping pieces, and the clamping pieces abut against the outside of the punch body 205. The top of the punch body 205 passes through the top of the positioning base 206 and extends into the outside.

[0029] Example 1: As Figure 1 As shown, the clamping component 204 consists of two clamping pieces. The punch body 205 is a single-hole die punch. Both clamping pieces abut against the outer side of the punch body 205, and the outer side of the clamping pieces abuts against the opposite side of the two semi-circular limiting pieces 203, so that the single-hole die punch can be squeezed and limited by the two clamping pieces.

[0030] Example 2: Figure 3 As shown, the clamping component 204 consists of three clamping pieces. The punch body 205 is a multi-hole die punch and is divided into two layers. At the same time, the top of the clamping piece is also provided with several through holes for the punch body 205 to pass through. The clamping piece abuts against the outside of the corresponding punch body 205 through the corresponding through holes, so that the multi-hole die punch can be clamped and positioned by the cooperation of the three clamping pieces and the through holes.

[0031] Example 3: Figure 4 As shown, the clamping component 204 consists of four clamping pieces. The punch body 205 is a multi-hole die punch and is divided into three layers. At the same time, the top of the clamping pieces is also provided with several through holes for the punch body 205 to pass through. The clamping pieces abut against the outer side of the corresponding punch body 205 through the corresponding through holes, so that the multi-hole die punch can be clamped and positioned by the cooperation of the four clamping pieces and the through holes.

[0032] In the above embodiment, the outer shape of the clamping piece 204 is unchanged, and the clamping piece 204 is divided into different numbers of clamping pieces by changing the number of layers and the number of each layer of the multi-hole die punch, and a through hole is provided on the top of the clamping piece for the punch to pass through, so as to facilitate the clamping and positioning of the multi-hole die punch with different numbers and layers, and when one of the punches is damaged, the entire die does not need to be replaced, only the individual punch needs to be disassembled and replaced.

[0033] The working principle of the above embodiment is:

[0034] When the punch body 205 needs to be replaced, the positioning base 206 can be conveniently clamped and clamped by the two second clamping grooves 302, and then conveniently rotated, so that it is removed from the outside of the support column 201 under the cooperation of the outer thread groove 202 and the inner thread groove 207, that is, the punch body 205 and the clamping piece 204 are taken out, the replaced punch body 205 is clamped on the inner side of the corresponding clamping piece 204, and the clamping piece 204 is placed on the top of the support column 201. Then move the two semicircular truncated limit pieces 203 to the outside of the clamping piece 204, move the positioning base 206 through the outside of the two semicircular truncated limit pieces 203 and to the outside of the support column 201, and rotate the positioning base 206 downward through the thread connection between the outer thread groove 202 and the inner thread groove 207. 207, until the inner wall of the positioning base 206 is abutted and limited by the outside of the two semicircular truncated limit pieces 203, that is, the replacement work of the punch body 205 is completed, which is convenient for directly replacing the punch body 205 when the punch body 205 is damaged, without the need to replace other parts.

[0035] Compared with the prior art, the upper and lower die with clamping is cooperated between the support column 201, the semicircular truncated limit piece 203, the clamping piece 204, the punch body 205 and the positioning base 206 on the top of the universal base 1, which can directly install and replace the punch through the separate structure design, so that the actual cost can be controlled to a certain extent. The clamping method can shorten the mold manufacturing cycle, thereby reducing the manufacturing cost, and saving the maintenance time to improve the actual production efficiency. At the same time, the disassembly and assembly method is very convenient and fast, which is convenient for the operator to operate, thereby effectively improving the practicability of the upper and lower die, solving the problem that the existing upper and lower die is mostly connected in a fixed way, which can only be replaced when damaged, resulting in high actual cost.
