Description

Technical Field

[0001] The invention relates to the technical field of stainless steel baking pan processing, in particular to flanging equipment for processing food-grade stainless steel baking pans. Background Art

[0002] In the processing technology of the one-piece stamped baking tray, the flanging processing of the frame is all done by the template method. Through the rotation of the template, the pneumatic cylinder presses the edge of the steel plate and rotates along with the rotation of the template. After one circle, the flanging processing of the baking tray is completed.

[0003] However, the flanging machines in the prior art are usually used for flanging round baking trays. When it comes to non-circular baking trays, the flanging wheel cannot keep in contact with the edge of the baking tray, and naturally cannot complete the flanging of the non-circular baking tray. In addition, after the flanging process is completed in the prior art, the baking tray is easily stuck in the mold cavity, requiring manual assistance for loading and unloading, and the degree of automation is insufficient, and the applicability is not strong.

[0012] Furthermore, the flanging assembly also includes a slide seat and a spring rod, the slide seat is slidably installed inside the guide rails on both sides, and the rear end of the slide seat is slidably matched with the rear plate through the spring rod.

[0013] Furthermore, the flanging assembly also includes a fitting wheel, the front end of the slide seat is slidably matched with the front plate through the fitting wheel, and the fitting wheel is tightly fitted with the circumference of the contoured cam under the elastic force of the spring rod.

[0014] Furthermore, the flanging assembly also includes an L-shaped piece and a sleeve, the L-shaped piece is welded and fixed on the top of the slide seat, and the sleeve is fixed on the end of the L-shaped piece.

[0016] The present invention provides a flanging device for processing food-grade stainless steel baking pans, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the formed baking tray is inverted on the lower die seat, and the edge of the baking tray protrudes from the step surface of the lower die seat. Then, under the drive of the lifting cylinder, the upper die seat descends and closes the mold with the lower die seat. The main body of the baking tray is located inside the mold cavity of the upper die seat. The mold release agent is applied in advance inside the mold cavity of the upper die seat to prevent the material from sticking during demolding. The flanging method for non-circular baking trays in this application is contour flanging. Specifically, according to the type of baking tray to be flanged, a production jig and upper and lower molds suitable for it are selected, and the lower die seat and the contour cam are scaled in proportion and synchronized. The center is set (this application takes a square baking tray as an example). The profiling cam and the lower die seat rotate synchronously under the drive of the motor. The upper die seat rotates at the output end of the lifting cylinder through the bearing, so it can also rotate synchronously with the lower die seat. Under the elastic force of the spring rod, the fitting wheel at the front end of the slide seat always maintains a close fit with the side wall of the profiling cam, and synchronously compensates for the offset angle of the baking tray when the lower die seat rotates, so that the flanging wheel is always in fit with the edge of the baking tray, thereby adapting to the flanging requirements of baking trays of different shapes, thereby improving the applicability of the flanging machine of this application.

[0018] 2. During the use of the present invention, after the flanging process of the current baking tray material is completed, the lifting cylinder pulls the upper die seat and the lower die seat to separate. The baking tray material after flanging is retained on the lower die seat, and the flipping cylinder is activated to lift the swing arm, so that the swing arms on both sides drive the production fixture located at one end of the fixed pin to rotate, so that the flipping angle of the lower die seat is greater than ninety degrees. Under the action of gravity, the baking tray material is located on the lower die seat and naturally falls off. Automatic unloading of baking tray material can be achieved without manual assistance, thereby improving production efficiency.

[0019] 3. During the use of the present invention, when the swing arms on both sides and the production jigs therein are turned over to realize the current baking tray unloading process, the space above the contour cam is no longer blocked by the production jig. At this time, under the control of the stepper motor, the material of the next baking tray is sent to the gap between the push rods on both sides via the stepper conveyor belt. Under the lifting action of the feeding cylinder, the push rods on both sides drive the next baking tray to be located above the reset position of the lower mold base. At this time, the baking tray received by the end of the push rod is located higher than the highest point of the swing arm circular path, and the push rod path matches the avoidance grooves on both sides of the production jig. The swing arm and the production jig inside it will not interfere with the position of the push rods on both sides and the next baking tray material they carry when they are reset. When the support feet at the end of the swing arm are connected with the fixed pin to achieve horizontal reset, the next baking tray material is just above the empty lower die seat. At this time, it is only necessary to reset the push rod to position the next baking tray material on the lower die seat, thereby ensuring the accuracy of automatic loading. The flanging machine of this application can realize automatic loading and unloading and contour flanging of baking tray materials according to the production steps. The process arrangement is reasonable, the process is simple and reliable, and the degree of automation is higher. BRIEF DESCRIPTION OF THE DRAWINGS

The flanging assembly 8 also includes a slide 804 and a spring rod 805. The slides 804 are slidably installed inside the guide rails 802 on both sides, and the rear end of the slide 804 is slidably matched with the rear plate 801 through the spring rod 805. The flanging assembly 8 also includes a fitting wheel 806, and the slide 80 The front end is slidably matched with the front plate 803 through the fitting wheel 806, and the fitting wheel 806 is tightly fitted with the circumference of the profiling cam 601 under the elastic force of the spring rod 805.

[0033] The specific operation is as follows: the formed baking tray is inverted on the lower die seat 610, and the edge of the baking tray protrudes from the step surface of the lower die seat 610. Then, under the transmission of the lifting cylinder 3, the upper die seat 4 descends and closes the mold with the lower die seat 610. The baking tray body is located inside the mold cavity of the upper die seat 4. The mold release agent is applied in advance to the mold cavity of the upper die seat 4 to prevent the material from sticking during demolding. The flanging method for non-circular baking trays in this application is contour flanging. Specifically, according to the type of baking tray to be flanging, a production jig 608 and upper and lower molds suitable for it are selected. The lower die seat 610 and the contour cam 601 are proportionally scaled and concentric. It is set that when the motor 602 drives the lower contour cam 601 to rotate synchronously with the lower die base 610, the upper die base 4 can also rotate synchronously with the lower die base 610 because it rotates at the output end of the lifting cylinder 3 through the bearing 5.

[0034] In summary, when the flanging equipment for processing food-grade stainless steel baking trays is used, the formed baking tray is inverted on the lower die seat 610, and the edge of the baking tray protrudes from the step surface of the lower die seat 610. Then, under the drive of the lifting cylinder 3, the upper die seat 4 descends and is molded with the lower die seat 610. The baking tray body is located inside the mold cavity of the upper die seat 4. The mold release agent is applied to the mold cavity of the upper die seat 4 in advance to prevent the material from being demolded and sticking. The flanging method for non-circular baking trays in this application is contour flanging. Specifically, according to the type of baking tray to be flanging, a production fixture 608 and upper and lower molds suitable for it are selected. The lower die seat 610 and the contour cam 601 are scaled in proportion and concentrically arranged (this application takes a square baking tray as an example). The contour cam 601 and the lower die seat 610 rotate synchronously under the drive of the motor 602. Since the die base 4 rotates at the output end of the lifting cylinder 3 through the bearing 5, it can also rotate synchronously with the lower die base 610. Under the elastic force of the spring rod 805, the fitting wheel 806 at the front end of the slide seat 804 always maintains a close fit with the side wall of the contoured cam 601, and synchronously compensates for the angle of deviation of the baking tray when the lower die base 610 rotates, so that the flanging wheel 809 always fits with the edge of the baking tray, thereby adapting to the flanging requirements of baking trays of different shapes, thereby improving the applicability of the flanging machine of the present application. After the flanging process of the baking tray material is completed, the lifting cylinder 3 pulls the upper die base 4 to separate from the lower die base 610, and the baking tray material after flanging is retained on the lower die base 610, and the flip cylinder 603 is activated to lift the swing arm 606, so that the swing arms 606 on both sides drive the production jigs therein. 608 is located at one end of the fixed pin 604 and rotates, so that the lower mold base 610 flips over at an angle greater than ninety degrees. Under the action of gravity, the baking tray material is located at the lower mold base 610 and falls off naturally. The baking tray material can be automatically unloaded without manual assistance, thereby improving production efficiency. When the swing arms 606 on both sides and the production fixture 608 therein flip to realize the current baking tray unloading process, the space above the profiling cam 601 is no longer blocked by the production fixture 608. At this time, under the control of the stepper motor, the next baking tray material is sent to the gap between the two side push rods 702 via the stepper conveyor belt 704. Under the lifting action of the feeding cylinder 701, the next baking tray is driven by the two side push rods 702 to be located above the reset position of the lower mold base 610. At this time, the baking tray received by the end of the push rod 702 is in The position is higher than the highest point of the circular path of the swing arm 606, and the path of the push rod 702 cooperates with the avoidance grooves 609 on both sides of the production jig 608, so that the swing arm 606 and the production jig 608 inside it will not interfere with the push rods 702 on both sides and the next baking tray material they carry when resetting. When the support feet 607 at the end of the swing arm 606 are connected with the fixing pin 604 to achieve horizontal resetting, the next baking tray material is just above the vacant lower mold base 610. At this time, it is only necessary to reset the push rod 702 to position the next baking tray material on the lower mold base 610, thereby ensuring the accuracy of automatic loading and unloading. The flanging machine of the present application can realize automatic loading and unloading and contour flanging of baking tray materials according to the production steps. The process arrangement is reasonable, the process is simple and reliable, and the degree of automation is higher.
