Description

Technical Field

[0001] The invention relates to the technical field of hardware processing, in particular to an automatic stamping device for hardware and a method thereof. Background Art

[0002] Hardware, as a metal processing product, plays an important role in modern life and industrial production. Choosing the right hardware is crucial to ensuring product quality, safety and service life. There are many types of hardware, and hardware needs to be stamped during processing. Specifically, external force is applied to the hardware to cause it to deform and bend, so as to obtain the desired shape of the workpiece, thereby completing the non-cutting stamping construction of the hardware. Therefore, stamping equipment is needed for processing and use in hardware production.

[0003] Reference is made to the automated hardware stamping equipment disclosed in the patent application with publication number CN118305227A. The stamping equipment realizes automatic rotation angle feeding through a plate transfer plate assembly. Every time it rotates an angle, the sheet metal in the corresponding plate positioning groove completes the positioning, stamping and unloading work, reducing the risk of manual operation.

[0004] The above-mentioned stamping equipment can realize the rotary feeding action through the plate transfer plate assembly, but the multi-station design makes the overall equipment occupy a large area and the space utilization rate is low, and it cannot be adapted to different processing environments. At the same time, the above-mentioned stamping equipment cannot complete the pre-processing of hardware and the mold itself. Therefore, in a long-term stamping environment, it is very easy to cause the mold temperature to rise and the wear to increase. There is a risk of thermal deformation, which causes the quality of the stamped products to decline. Summary of the invention

[0063] The limiting frame 4 is slidably arranged on the lower die base 2 for limiting the hardware sheet. The front end of the limiting frame 4 is open in design, and the limiting frame 4 is through-designed. A reserved area is arranged at the bottom of the limiting frame 4 near the pushing cylinder 5, so that the limiting frame 4 can be separated from the lower die base 2, which is beneficial to the subsequent pretreatment mechanism. A pushing cylinder 5 is installed on one side of the lower die base 2 and is transmission-connected to the back of the limiting frame 4. The pushing cylinder 5 cooperates with the limiting frame 4 to complete the follow-up movement of the hardware sheet, and slideways are symmetrically provided on the upper surface of the lower die base 2. Slide bars are integrally arranged on both sides of the lower surface of the limiting frame 4. The two slide bars are correspondingly slidably engaged in the two slideways. Two blocking members for limiting the hardware sheet are symmetrically arranged on the inner wall of the front end of the limiting frame 4;

[0064] It is worth mentioning that when restricting and unloading metal sheets: a restriction frame 4 is provided to control the push cylinder 5 to reset to a predetermined position. At this time, the metal sheets are fixed on the lower die base 2 by the restriction frame 4, and the two blocking members are used to restrict the metal sheets in multiple directions, waiting for subsequent stamping. After the stamping is completed, the push cylinder 5 is controlled to work, driving the restriction frame 4 and the metal sheets to move out of the lower die base 2.

[0065] The feeding mechanism is arranged on the frame 101 to realize the active feeding action of the object plate, and the step-by-step processing of unloading and loading of the object plate is completed through the cooperation of the feeding mechanism and the limiting frame 4;

[0067] The pre-processing mechanism is combined and arranged on the limiting frame 4 and the feeding mechanism, and the pre-processing mechanism and the limiting frame 4 are linked and coordinated. When the limiting frame 4 performs the loading and unloading action, the pre-processing mechanism is synchronously linked to complete the step-by-step pre-processing of the lower die base 2 and the hardware plate. The pre-processing mechanism is divided into a control part, a No. 1 processing part and a No. 2 processing part, and the switching control of the No. 1 processing part and the No. 2 processing part is completed by the control part;

[0068] like Figure 5 As shown, each blocking member comprises:

[0069] A reserved groove 6 is provided at the front end of the inner wall of the limiting frame 4, a stopper 7 is slidably engaged in the reserved groove 6, a plurality of No. 1 springs 8 are provided between the stopper 7 and the reserved groove 6, the plurality of No. 1 springs 8 push the stopper 7 to move out of the reserved groove 6, and an exhaust hole for exhaust is provided at the tail end of the reserved groove 6, a slope 9 is provided on the outer wall of the stopper 7, and the slope 9 is provided toward the side of the feeding mechanism.

[0070] Among them, electrical components such as the punching machine 1, the pushing cylinder 15, the loading cylinder 12 and the pushing cylinder 5 are all connected to switches through wires, and the switches are electrically connected to the controller, and the specific structure of the controller is not limited.

[0071] Embodiment 2: Based on the feeding mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the feeding mechanism.

[0072] like Figure 3 , Figure 6 and Figure 7 As shown, the feeding mechanism comprises:

[0073] The upper barrel 10 is arranged at a distance on one side of the lower die base 2, and a material receiving box is arranged on the frame 101 at one side of the upper barrel 10. The top and bottom of the upper barrel 10 are open in design, and the top of the upper barrel 10 is parallel to the lower die base 2, which is convenient for loading. Specifically, the upper barrel 10 is arranged on the frame 101 through a bracket, and the upper barrel 10 and the lower die base 2 are arranged at a distance, so that the processed hardware sheet can be gravity-fed through the distance between the upper barrel 10 and the lower die base 2, and a loading port is arranged on the side of the upper barrel 10 facing the lower die base 2, so that the front end of the hardware sheet in the upper barrel 10 can be smoothly pushed out, and a push plate 11 is slidably arranged at the bottom of the upper barrel 10, and a loading cylinder 12 connected to the push plate 11 is installed at the bottom of the upper barrel 10 through a bracket;

[0074] A concave seat 13 is arranged at the top of the outer wall of the loading barrel 10, and a loading plate 14 is hidden at the top of the outer wall of the loading barrel 10. The loading barrel 10 is provided with a storage area matched with the loading plate 14, and a pushing cylinder 15 drivingly connected to the loading plate 14 is installed on the concave seat 13;

[0075] The feeding mechanism comprises:

[0076] like Fig. 9 As shown, two support members are symmetrically arranged between the upper barrel 10 and the lower die seat 2 to support the loading of the hardware plate. Each support member includes a crossbeam 16. The two ends of the crossbeam 16 are respectively fixedly connected to the side wall of the upper barrel 10 and the lower die seat 2. A plurality of slides 17 are arranged at intervals on the crossbeam 16. The number of slides 17 can be freely increased or decreased according to the loading requirements. A slide 18 is slidably engaged on each slide 17. The slide 18 can extend out of the slide 17 to complete the length extension. A push rod 19 connected to the back of the slide 18 is slidably penetrated at the tail of the slide 17, and a linkage plate 20 is commonly connected to the tails of the plurality of push rods 19.

[0077] It is worth mentioning that when loading the hardware sheet metal parts: by providing a loading mechanism, when the limiting frame 4 performs the unloading action on the hardware sheet metal parts, the pushing cylinder 15 is started synchronously, and the loading plate 14 is controlled to push the hardware sheet metal parts at the top of the loading barrel 10 to move. The hardware sheet metal parts first contact the block 7 of the blocking member, and under the guidance of the inclined surface 9 of the block 7, the block 7 compresses the No. 1 spring 8 to shrink into the reserved groove 6, so that the hardware sheet metal parts can smoothly enter the limiting frame 4. After the hardware sheet metal parts are pushed into the limiting frame 4, the No. 1 spring 8 pushes the block 7 to reset and restricts the hardware sheet metal parts again. The blocking member completes the unidirectional movement restriction of the hardware sheet metal parts, which is beneficial to the loading and unloading operations. After the loading is completed, the pushing plate 11 is controlled to move upward by the loading cylinder 12 to complete the upward compensation of the hardware sheet metal parts, which is beneficial to continuous loading and unloading.

[0078] Two sensing members are correspondingly mounted on the cross beams 16 of the two supporting members, and the synchronous triggering of the multiple slides 18 on the two supporting members is completed by the two sensing members. Each sensing member includes a sensing cavity 21 with an open design on one side. The sensing cavity 21 is connected to the cross beam 16 through a bracket. A No. 1 piston member 22 connected to the linkage plate 20 is slidably mounted in the sensing cavity 21. A No. 2 spring is installed between the No. 1 piston member 22 and the sensing cavity 21. The No. 2 spring is used to pull the slide 18 to return to the slide seat 17;

[0079] It is worth mentioning that in order to improve the stability of feeding of hardware sheets, during the forward pushing of the hardware sheets, the feeding plate 14 moves to release the No. 2 piston member 24, and under the reset action of the No. 3 spring, the No. 2 piston member 24 is pushed to move and the medium in the trigger chamber 23 is sent into the sensing chamber 21, so that the No. 1 piston member 22 overcomes the No. 2 spring to complete the telescopic action, and the linkage plate 20 controls the forward movement of multiple push rods 19, so that the slide 18 is telescoped on the slide seat 17 to complete the length extension, and the slide 18 is used to support and limit the two sides of the bottom of the hardware sheet to avoid the problem of the hardware sheet falling, thereby ensuring the stability of feeding, and the slide 18 and the slide seat 17 adopt a contraction design to avoid interference with the unloading of the hardware sheet. After the feeding is completed, the feeding plate 14 is reset to squeeze and reset the No. 2 piston member 24, so that the No. 1 piston member 22 is reset and the multiple slides 18 are linked to reset synchronously. Such a design reduces the control difficulty, enables the support member to follow the feeding plate 14 to complete the follow-up cooperation, and improves the feeding efficiency.

[0098] It is worth mentioning that: when the pretreatment of the hardware sheet and the lower die base 2 is completed in steps: by providing a pretreatment mechanism, when the hardware sheet is unloaded, the limiting frame 4 will drive the No. 3 piston 26 to move in the extrusion chamber 25, and send the oil in the front end space of the extrusion chamber 25 out through the No. 1 output pipe 28, and spray the oil evenly on the hardware sheet waiting for loading at the top of the loading barrel 10 through the straight-face spray chamber 33 to complete the pretreatment. During the movement of the No. 3 piston 26, the oil is replenished into the extrusion chamber 25 through the No. 2 input pipe 29 to complete the circulation. At the same time, under the design of the push arm 34, the straight-face spray chamber 33 completes the moving spraying under the restriction of the slide rail 31, which expands the spraying space and can quickly complete the pretreatment of the hardware sheet.

When the No. 3 piston member 26 moves, the oil is replenished into the extrusion chamber 25 through the No. 1 input pipe 27 to complete the circulation. Under this action, the oil delivered by the No. 2 output pipe 30 first enters the pushing chamber 39 of the lifting member, pushing the No. 4 piston member 40 to extend, so that the roller 41 contacts the inclined platform 38 to complete the extrusion, and the lifting platform 36 compresses the No. 4 spring to complete the descent, so that the profiling spray chamber 37 reaches the predetermined spraying height, and the No. 4 piston member 40 exposes the diverter pipe 42 during the extension, and delivers the oil into the profiling spray chamber 37 through the diverter pipe 42. At the same time, the No. 2 output pipe 30 can be connected with the profiling spray chamber 37 through the pipeline, and the connection state of the lifting member can be freely selected by the staff.

[0099] Embodiment 4: A method for automated stamping of hardware, the method comprising the following steps:

[0100] Step 1: First, assemble the limiting frame 4 on the lower die base 2, and use the limiting frame 4 to limit the metal plate on the lower die base 2;

[0101] Step 2, then control the punching machine 1 to work, prompt the punching die 3 to descend and contact with the lower die base 2, complete the punching and forming of the metal plate, and at the same time control the movement of the limiting frame 4 to complete the automatic unloading of the metal plate;

[0102] Step 3: Actively compensate the metal panels stored therein into the limiting frame 4 through the feeding mechanism to complete the stable feeding of the metal panels;

[0103] Step 4: By providing a pretreatment mechanism, the pretreatment work of the metal plate on the loading mechanism and the lower die base 2 can be completed in steps during the loading and unloading action of the limiting frame 4.

[0104] The present invention provides an automatic stamping equipment and method for hardware parts, and the specific working principle is as follows: first, the limiting frame 4 is assembled on the lower die base 2, and the hardware plate is limited on the lower die base 2 by means of the limiting frame 4, and then the punching machine 1 is controlled to work, so that the punching die 3 is prompted to descend and contact with the lower die base 2 to complete the stamping forming of the hardware plate. By adopting the sliding setting of the limiting frame 4, after a single stamping is completed, the stamped hardware plate is controlled by the limiting frame 4 to move out of the lower die base 2, and the hardware plate falls into the receiving box under the action of gravity to complete automatic unloading, and then the feeding mechanism is controlled to actively compensate the hardware plate stored in it through the feeding mechanism. Inside the limiting frame 4, the supporting parts are synchronously controlled to provide bottom support for the hardware panels inside the limiting frame 4, so as to ensure the stable loading of the hardware panels. Through the coordinated operation of the loading mechanism and the limiting frame 4, the automatic loading and unloading of the hardware panels can be completed, which occupies a small area, is convenient for construction, and reduces the subsequent maintenance workload. At the same time, a pretreatment mechanism is provided. During the loading and unloading action of the limiting frame 4, the pretreatment work of the hardware panels on the loading mechanism and the lower die base 2 can be completed in steps, so that the stamping work can be carried out safely and stably, avoiding the problem of the temperature rise of the lower die base 2 affecting the product quality of the hardware panels, and improving the surface quality of the hardware panels.
