Description

Technical Field

[0001] The utility model relates to the field of cold stamping dies, in particular to a feeding structure for automatically picking up and placing products in a progressive die. Background Art

[0002] The progressive die is composed of multiple stations, each of which completes different processing in sequence. A series of different stamping processes are completed in one stroke of the punch press. After a stroke is completed, the punch press feeder moves the material forward according to a fixed step distance. In this way, multiple processes can be completed on a die.

[0003] When traditional molds are used to stretch and form products, they need to go through multiple processes including stretching, shaping, forming, and side shearing. Each process corresponds to a mold that completes the stamping and forming. It is impossible to stamp the product in one go. In addition, it is necessary to manually take down the products that have completed the corresponding processes and place them on another mold for stamping. As a result, there will be problems such as low production efficiency, long production time, large number of production equipment occupied, and high labor costs. Therefore, a feeding structure that can continuously stamp, complete multiple processes in one molding, and automatically take and place products is needed. Utility Model Content

[0029] See also Figures 1 to 3 As shown, the utility model provides the following technical solutions: a feeding structure for automatically picking up and placing products in a progressive die, comprising an upper die and a lower die, the upper die being provided with an even number of slotting knives 11, two longitudinal movable guide rails 14 slidingly provided on the lower die being provided with lower driving blocks 16 cooperating with the even number of slotting knives 11, a tension spring 25 being provided between the two oppositely provided lower driving blocks 16, when the die is closed, the four corners of the upper die base 2 are fixedly provided with slotting knives 11 in pairs, and correspondingly cooperate with the lower driving blocks 16 provided on the two longitudinal movable guide rails 14 of the lower die base 13, the slotting knives 11 push the lower driving blocks 16 downwards, and the two pairs of the longitudinal movable guide rails 14 are slidingly provided with transverse movable guide rails 14. The movable guide rail 15, the longitudinal movable guide rail 14 and the transverse movable guide rail 15 all move along the slide rail through the internal slider. The two transverse movable guide rails 15 move relative to each other along the longitudinal movable guide rail 14. Several relatively arranged manipulators 23 are vertically arranged on the transverse movable guide rail 15 and are opened one after another. When the mold is opened, the inserting knife 11 is separated from the lower driving block 16. The lower driving block 16 contracts under the action of the tension spring 25, thereby driving the several manipulators 23 on the two transverse movable guide rails 15 to clamp the processed products on the workstation. Subsequently, the electronic valve time controller 22 is used to control the cylinder 20 to push the several manipulators 23 on the two transverse movable guide rails 15 to clamp the product to the mobile workstation left and right, thereby achieving an automatic loading and placing process.

[0030] In this embodiment, the upper template 1 is provided with an upper clamping plate 3 that cooperates with the upper die base 2. The material is intermittently conveyed to the lower die through the conveying device, and the lower die and the upper die are continuously opened and closed. The upper die base 1 is provided with a blanking punch 6, a deep drawing punch 7, a shaping punch 8, a forming punch 9, and a side shear blanking punch 10 in sequence along the feeding direction, which are matched and separated with the lower die base 13 to automatically stamp the workpiece. The two ends of the upper clamping plate 3 are provided with inner guide columns 5 to connect the stripping plate 4, which play the role of limiting guidance and also It can prevent the stripping plate 4 from shaking left and right, ensuring accurate and reliable stamping; the upper end face of the lower die base 13 is provided with two rows of horizontal movable guide rails 15 distributed along its length direction, and between the two rows of horizontal movable guide rails 15 are arranged in sequence along the material entry direction a blanking trough 100, a deep drawing trough 101, a shaping trough 102, a forming trough 103, and a side shear blanking trough 104, and the manipulators 23 are fixedly connected between the two horizontal movable guide rails 15 in pairs for picking up and placing workpieces after completing the previous process.

[0031] Specifically, the contact surfaces of the two longitudinal movable guide rails 14 and the lower die base 13 are provided with longitudinal wear-resistant plates 18, and the two transverse movable guide rails 15 are slidably set on the longitudinal movable guide rails 14 through transverse wear-resistant plates 17, and slide on the slide rails by relying on their internal sliders. When the transverse movable guide rails 15 and the longitudinal movable guide rails 14 move left and right and front and back on the wear-resistant plates respectively, they have good wear resistance, can withstand the impact and wear during the stamping process, and improve the service life of the components.

[0032] Specifically, a cylinder 20 is provided on the left side of the lower mold plate 1, and the cylinder 20 is connected to one end of the left side of the two horizontal movable guide rails 15 through a fixed plate 24. The lower mold is installed with an electronic valve time controller 22, and the cylinder 20 is connected and controlled through an air pipe 21 to drive the two horizontal movable guide rails 15 to move horizontally left and right.

[0033] like Figures 4 and 5 As shown in the figure, this product is a motor cover formed by stretching. Due to the product structure, it requires multiple processes A-cutting, B-stretching, C-shaping, D-forming, and E-side shearing. Now, the five processes can be integrated into a punch press, and an automatic gripping and feeding robot is used. The robot clamps the product and conveys it at different processes to form a flow operation, which will greatly reduce production costs and improve production efficiency.

[0034] The working principle and specific operation process of this utility model are as follows:

[0035] The feeding structure of this progressive die for automatic pick-up and placement of products utilizes the kinetic energy of the vertical stamping of the upper die, and uses the insert 11 to drive the lower drive block 16. The lower drive block 16 drives the two longitudinal movable guide rails 14, and realizes forward and backward movement under the expansion and contraction of the tension spring 25. The transverse movable guide rail 15 is slidably set on the longitudinal movable guide rail 14 through the transverse wear-resistant plate 17. The manipulator 23 is fixed between the two transverse movable guide rails 15, which can realize automatic clamping and loosening functions. The movement of the transverse movable guide rail 15 is controlled by the cylinder 20 in conjunction with the electronic valve time controller 22 to control the left and right movement step of the transverse movable guide rail 15, and the processed product clamped by the mobile manipulator 23 is moved to the next workstation for the next process, and so on.

[0036] When the upper die is pressed down, the insert knife 11 drives the lower drive block 16, and the longitudinal movable guide rails 14 move back and forth respectively, pushing the manipulator 23 to release the product. The manipulator 23 retreats to both sides of the stamping groove. The product has completed the stamping process in the die. At this time, the transverse movable guide rail 15 moves one step to the left under the action of the cylinder 20. When the upper die rises, the insert knife 11 leaves the lower drive block 16, and the longitudinal movable guide rail 14 drives the manipulator 23 to clamp the product under the action of the tension spring 25. At the same time, the electronic valve time controller 22 controls the cylinder 20 to push the five manipulators 23 on the transverse movable guide rail 15 to move the product one step to the right respectively. This stroke completes the processing steps of automatic pick-up and place of products in the progressive die stamping. Through the cooperation of five punches and five stamping grooves, the approximate outline of the product is pressed out, and the manipulator 23 automatically picks up and places the product on another stamping groove for further stamping to finally form a complete product.

[0037] This structure is cleverly designed, shortens the production cycle, saves a lot of production costs, and can be widely used in the progressive die production of similar products.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
