Description

Technical Field

[0001] The utility model belongs to the field of production line processing, and particularly relates to a rapid die change mechanism for a production line. Background Technique

[0002] The die change process refers to the process of replacing different dies during production to meet different product or production requirements. This process is very crucial in many manufacturing industries, especially in the fields of injection molding, stamping, casting, sheet metal processing, etc.

[0003] In actual production, on a production line with two types of products in one die, the existing dies cannot be scheduled simultaneously. For example, in the existing dies, rapid die change cannot be achieved in the OP20 process and the OP30 process. Each time of die change requires transferring the die from the machine table to the site for die disassembly, resulting in huge waste of time cost and machine waiting time cost. The replacement time is long, it is easy to make mistakes, the efficiency is low, the labor cost is high, and spare parts are not easy to manage. Considering the actual production, local process modifications are made to the original die to achieve rapid die change after die disassembly, reduce the die change time, and reduce the waiting time of the die on and off the machine table. Content of the Utility Model

[0010] It further includes a first punch and a second punch which are fitted and arranged in the punch clamping plate die change component.

[0011] As a further improvement of the present utility model, a plurality of waist-shaped holes are provided on the side surface of the punch seat, and fitting blocks are fitted in the waist-shaped holes. A plurality of lateral punches are provided on the side surface of the baffle seat. A plurality of the lateral punches correspond to one of the waist-shaped holes in sequence and are fitted in the fitting blocks, and one of the lateral punches in the middle slides in the waist-shaped hole corresponding to it.

[0012] As a further improvement of the present utility model, the baffle slides in the slot and abuts against the side surface of the lateral punch in the middle.

[0013] As a further improvement of the present utility model, two pin holes are provided on the side surface of the punch head seat, and pin shafts are inserted in the pin holes.

[0029] Among them, a baffle replacement component 2 is assembled and arranged in the OP20 process die 1; a punch holder replacement component 4 is assembled and arranged in the OP30 process die 3;

[0030] The baffle replacement component 2 includes a baffle seat 21 assembled in the OP20 process die 1, and a punch seat 25 is assembled on the side of the baffle seat 21;

[0031] A slot 26 is provided on the upper end surface of the punch seat 25, and a baffle 22 is inserted into the slot 26;

[0032] The punch holder replacement component 4 includes a punch seat 41 assembled in the die 3 of the OP30 process. A central hole 42 and two side holes 43 are provided on the punch seat 41;

[0033] It further includes a first punch 5 and a second punch 6 fitted into the punch holder replacement component 4.

[0034] In this embodiment, the punch holder replacement component 4 of the present application realizes rapid replacement operation of the first punch 5 and the second punch 6 on the punch holder replacement component 4 by digging a groove on the insert block in the original process and adding side shafts 51 and side columns 61 to the sides of the first punch 5 and the second punch 6 to match the groove parts on the punch holder replacement component 4. Through the replacement operation of the punch holder replacement component 4, the first punch 5 and the second punch 6, in actual production, the present application solves the high-cost problem of the time for disassembling and assembling the upper and lower dies of the replacement die and the cost problem of the time for the die repair master to move back and forth between the hoisting and repair areas and the replacement cost.

[0035] For the rapid die replacement mechanism of the production line of the present utility model, through the assembly cooperation between the die 1 of the OP20 process and the baffle replacement component 2, in actual use, the present application replaces the three groups of lateral punches 23 fixedly arranged in the original process with lateral punches 23 fixedly arranged on both sides and slidably arranged in the middle, so that when the shearing requirement of the workpiece changes, the shearing process replacement can be quickly realized, avoiding the overall disassembly and replacement of the baffle replacement component 2. At the same time, compared with the original process, the modification action of the lateral punch 23 of the present application is smaller, the cost is lower, the production cycle is shortened, and the production batch is reduced.

[0036] Specifically, referring to Figures 1-3 , a plurality of waist-shaped holes 27 are provided on the side surface of the punch seat 25, and fitting blocks 24 are fitted into the waist-shaped holes 27. A plurality of lateral punches 23 are provided on the side surface of the baffle seat 21; a plurality of lateral punches 23 correspond to one of the waist-shaped holes 27 in sequence and are fitted into the fitting block 24, and one of the lateral punches 23 in the middle slides in the corresponding waist-shaped hole 27; the baffle 22 slides in the slot 26 and abuts against the side of the lateral punch 23 in the middle.

[0037] In this embodiment, when the user removes the baffle 22 from the slot 26, at this time, the set lateral punch 23 will lose the tight abutment of the baffle 22 and then retreat into the waist-shaped hole 27. At this time, the lateral punch 23 arranged in the middle will not participate in the subsequent shearing operation; in the preferred embodiment, when the workpiece is subjected to the shearing operation of the lateral punch 23, only two shearing waist-shaped holes will be generated on the workpiece at this time;

[0038] Further, when the user inserts the baffle 22 into the slot 26 again, the lateral punch 23 in the middle will be abutted by the baffle 22 and then move forward. At this time, the three lateral punches 23 provided will be on the same horizontal plane. When the three lateral punches 23 perform shearing operations synchronously, three shearing waist holes can be generated on the workpiece.

[0039] Specifically, referring to Figures 4-7 , two pin holes 44 are provided on the side surface of the punch holder 41, and pin shafts are inserted into the pin holes 44; a first punch column 52 is integrally provided on the upper end surface of the first punch 5; a small punch column 62 is integrally provided on the upper end surface of the second punch 6.

[0040] In this embodiment, in the actual production process, as shown in Embodiment Figure 7 , the sizes of the side shafts 51 and the side holes 43 are adapted to each other, and the sizes of the side columns 61 are also adapted to the sizes of the side holes 43. Therefore, the first punch 5 and the second punch 6 provided can be replaced and assembled on the punch holder replacement component 4.

[0041] In a preferred embodiment, as shown in Embodiment Figure 7 , when the user needs to install the first punch 5 on the punch holder replacement component 4, by aligning the first punch 5 with the center hole 42 and making the two side shafts 51 on the side of the first punch 5 opposite to the side holes 43, and then the user presses the first punch 5 into the punch holder 41, the quick insertion between the first punch 5 and the punch holder replacement component 4 can be completed at this time.

[0042] Further, by aligning the second punch 6 with the center hole 42 and inserting the side column 61 into the side hole 43, the quick insertion between the second punch 6 and the punch holder replacement component 4 can be completed at this time.

[0043] The rapid die change mechanism for a production line of the present utility model:

[0044] The first step: In actual use, when the user needs to switch between the first punch 5 and the second punch 6, the first punch 5 is aligned with the central hole 42, and the two side shafts 51 on the side of the first punch 5 are opposite to the side holes 43. Then the user presses the first punch 5 into the punch seat 41. At this time, the quick insertion between the first punch 5 and the punch clamping plate conversion assembly 4 can be completed. At the same time, when the first punch 5 needs to be converted, by taking out the first punch 5, then aligning the second punch 6 with the central hole 42, and inserting the side post 61 into the side hole 43. At this time, the quick insertion between the second punch 6 and the punch clamping plate conversion assembly 4 can be completed. The punch clamping plate conversion assembly 4 of the present application realizes quick conversion operation between the first punch 5 and the second punch 6 on the punch clamping plate conversion assembly 4 by grooving on the insert block in the original process and adding side shafts 51 and side posts 61 to the sides of the first punch 5 and the second punch 6 to match the groove parts on the punch clamping plate conversion assembly 4;

[0045] The second step: In actual use, when the user removes the baffle 22 from the slot 26, the lateral punch 23 provided at this time will lose the tight contact of the baffle 22 and then retreat into the kidney-shaped hole 27. At this time, the lateral punch 23 provided in the middle will not participate in the subsequent shearing operation. When the user inserts the baffle 22 into the slot 26 again, the lateral punch 23 located in the middle will be abutted by the baffle 22 and then move forward. At this time, the three lateral punches 23 provided will be on the same horizontal plane. When the three lateral punches 23 perform shearing operations synchronously, three shearing kidney-shaped holes can be generated on the workpiece.
