Description

Technical Field

[0001] The present invention relates to the technical field of cookware processing, and in particular to a processing device and a processing method for cookware production. Background Art

[0002] As a cooking utensil, cookware has various classifications, such as frying pans, hot pot pans, steamers, etc. Among them, steamers are mainly used for steaming food. In order to achieve multi-layer steaming, there are inwardly concave rolling convex members on the side wall of the steamer for placing steaming racks.

[0003] In the production process of existing steamers, since the groove is inwardly concave, the processing of the inner groove cannot be completed during stamping. Usually, after the steamer is stamped into a straight barrel, the formed steamer is placed on a rolling press to roll the groove, and two devices are used to complete the production of the steamer. Summary of the Invention

[0004] The present invention aims at the deficiencies in the prior art and provides a processing device and a processing method for cookware production.

[0005] To solve the above technical problems, the present invention is solved by the following technical solutions: A processing device for cookware production includes a stamping machine and a rolling member. The stamping machine includes a pressing member, a forming punch and a forming die. The forming punch is formed by combining a first convex member and a second convex member, and the second convex member is slidably arranged on the first convex member in a guiding manner. A rotating member is arranged on the pressing member, and the first convex member is arranged on the rotating member. The rotating member can drive the forming punch to rotate, and a first locking member for locking the second convex member on the first convex member is arranged on the first convex member. An insertion groove and a forming groove are formed on the second convex member. The forming cavity of the forming die is formed by combining a bottom cavity, a rotating cavity and an upper cavity. The bottom cavity is fixedly arranged on the equipment base plate, the rotating cavity is slidably arranged on the bottom cavity, and the upper cavity is rotatably arranged on the rotating cavity. The rolling member includes a guide rail, a rotating frame and a sliding frame. The track is arranged on the equipment base plate, the rotating frame is rotatably arranged on the track, and the rotation trajectory is coaxial with the forming cavity of the forming die. A sliding groove is arranged on the rotating frame, and the sliding frame is elastically limited and guided to slide in the sliding groove. An electromagnet and a roller frame are arranged at the upper end of the sliding frame. A guiding cavity is formed on the rotating cavity, and the roller frame is guided to slide in the guiding cavity and is elastically guided to slide on the sliding frame at the same time. After the electromagnet is energized, it can be magnetically adsorbed in the insertion groove, so that the sliding frame moves towards the axis of the forming die cavity, and the roller on the roller frame abuts against the outer wall of the formed part and is arranged in cooperation with the forming groove. After the electromagnet is inserted, the first locking member is automatically unlocked, the first convex member moves upward under the action of the pressing member, the second convex member is locked by the sliding frame and remains stationary, and the rotating member rotates to drive the forming punch and the rolling member to rotate together to complete the rolling of the inner groove of the formed part.

[0006] Its beneficial effects are as follows. When stamping and forming cookware, it automatically completes the rolling of the inner groove on the side wall of the straight-barrel cookware, thereby reducing the time for clamping and handling, reducing the production process, improving production efficiency, reducing equipment investment, and lowering production costs.

[0007] In the above solution, preferably, the second convex part includes an upper convex block and a lower convex block. The inner side of the upper end of the lower convex block is rotationally limited and arranged on the lower end surface of the upper convex block. A first concave surface is provided on the upper convex block, and a second concave surface is provided on the lower convex block. After the upper convex block and the lower convex block are combined, the first concave surface and the second concave surface are combined to form a complete forming groove. The insertion groove is provided on the upper convex block, and a second locking part is provided on the upper convex block. After the electromagnet is inserted into the insertion groove, the upper convex block and the lower convex block are locked together.

[0008] In the above solution, preferably, a first sliding part is elastically slidably arranged in the insertion groove, and a second sliding part is elastically slidably arranged in the lower end surface of the upper convex block. The rear end of the first sliding part is connected to the rear end of the second sliding part by a first pulling rope. A locking hole is provided on the upper end surface of the lower convex block. After the electromagnet is inserted into the insertion groove, it presses on the first sliding part, thereby relaxing the first pulling rope, causing the second sliding part to slide into the locking hole, and locking the upper convex block and the lower convex block together.

[0009] In the above solution, preferably, a first elastic part is provided at the rear end of the first sliding part in a top-touch manner, and a second elastic part is provided at the rear end of the second sliding part in a top-touch manner. The elastic force of the first elastic part is greater than that of the second elastic part.

[0010] In the above solution, preferably, a limiting sliding groove is provided on the first convex part, and sliding convex blocks are provided on the side walls of the upper convex block and the lower convex block. The upper convex block and the lower convex block are slidably arranged in the limiting sliding groove through the sliding convex blocks for limiting and guiding, and the length of the limiting sliding groove is greater than the height of the forming part.

[0011] In the above solution, preferably, the inner wall diameters of the bottom cavity and the upper cavity are the same and are the size of the outer wall of the forming part. The inner wall diameter of the rotating cavity is greater than the inner wall diameters of the bottom cavity and the upper cavity. Therefore, during forming, the outer wall of the forming part does not contact the inner wall of the rotating cavity, and when the sliding frame rotates driven by the forming punch, it drives the rotating cavity to rotate together.

[0012] In the above solution, preferably, a third elastic part is sleeved on the roller frame. One end of the third elastic part touches the sliding frame, and the other end touches the roller frame. A fourth elastic part is provided in the sliding groove, and both ends of the fourth elastic part respectively touch the front end surface of the sliding groove and the front wall of the sliding frame.

[0013] In the above solution, preferably, the lower convex block is divided into a first lower convex block and a second lower convex block. The second lower convex block is arranged in a limited and guided sliding manner on the bottom surface of the first lower convex block. There is a gap groove between the first lower convex block and the second lower convex block. After the first convex member and the second convex member are combined, the first locking member can extend forward and penetrate into the gap groove, thereby locking the second convex member on the first convex member.

[0014] A processing method of a processing device for pot production:

[0015] S1: Place the sheet on the forming female die, and the pressing member drives the forming male die to press down to complete the straight barrel forming of the sheet.

[0016] S2: The electromagnet is energized and inserted into the insertion groove to integrally connect the sliding frame and the second convex member, while limiting the second convex member. At the same time, the roller on the roller frame abuts against the outer wall of the formed part.

[0017] S3: The pressing member rises and drives the first convex member to rise together, while the second convex member remains stationary.

[0018] S4: The rotating member rotates to drive the sliding frame and the second convex member to rotate together, so that the roller completes the rolling of the inner groove on the side wall of the straight barrel formed part.

[0019] The beneficial effects of the present invention are as follows: The present invention provides a processing device for pot production and its processing method, which can automatically complete the rolling of the inner groove on the side wall of the straight barrel pot during the stamping and forming of the pot, thereby reducing the time of secondary clamping and material handling, reducing the production process, improving the production efficiency, reducing the equipment investment, and lowering the production cost.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes: Refer to Figures 1-7 ,

[0028] A processing device for pot production includes a stamping machine 1 and a rolling member 2. The stamping machine 1 includes a pressing member 11, a forming punch 12 and a forming die 13. The pressing member 11 includes a rotating member 111, a lifting plate 112, a lifting oil cylinder 113 and an equipment chassis 114. The lifting oil cylinder 113 is arranged on the equipment chassis 114. The lifting plate 112 is guided and slidably arranged on the equipment chassis 114 and is connected to the telescopic rod of the lifting oil cylinder 113. The rotating member 111 includes a rotating motor 1111 and a rotating disc 1112. The rotating disc 1112 is rotatably arranged on the bottom surface of the lifting plate 112. The rotating motor 1111 is arranged on the upper end surface of the lifting plate 112, and the rotating shaft is connected to the rotating disc 1112.

[0029] Wherein the lifting oil cylinder 113 extends downward to drive the rotating member 111 to move downward, and the rotating motor 1111 rotates to drive the rotating disc 1112 to rotate.

[0030] The forming cavity of the forming die 13 is formed by combining a bottom cavity 131, a rotating cavity 132 and an upper cavity 133. The bottom cavity 131 is fixedly arranged on the bottom surface of the equipment chassis 114. Annular limiting grooves are opened on the upper end surface of the bottom cavity 131 and the lower end surface of the upper cavity 133. The upper and lower ends of the rotating cavity 132 are respectively rotatably arranged in the limiting grooves of the bottom cavity 131 and the upper cavity 133, so that both the rotating cavity 132 and the upper cavity 133 can rotate freely. The inner wall diameters of the bottom cavity 131 and the upper cavity 133 are the same and are used in cooperation with the forming punch 12 to form a straight-barrel pot. The inner wall diameter of the rotating cavity 132 is larger than the inner wall diameters of the bottom cavity 131 and the upper cavity 133. When forming a straight-barrel pot, the inner wall of the rotating cavity 132 does not touch the outer wall of the formed part. After forming, the inner wall of the upper cavity 133 contacts the outer wall of the formed part and cannot rotate under the action of friction, while the rotating cavity 132 does not contact the formed part and can thus rotate. A guiding cavity 1321 is opened on the side wall of the rotating cavity 132.

[0031] The forming punch 12 includes a first convex member 121 and a second convex member 122. A limiting chute 1211 is formed on the side wall of the first convex member 121. The second convex member 122 includes an upper convex block 1223 and a lower convex block 1224. Sliding convex blocks 1226 are arranged on both sides of the upper convex block 1223 and the lower convex block 1224, and are arranged in the limiting chute 1211 in a limiting and guiding sliding manner. An elastic rope cavity 1212 is formed at the upper end of the limiting chute 1211. One end of an elastic rope 1213 is arranged in the elastic rope cavity 1212, and the other end is connected to the upper end of the second convex member 122. The first convex member 121 is arranged on the rotating disk 1112 and is coaxial with the rotating disk 1112. The rotation of the rotating disk drives the first convex member 121 to rotate, and the first convex member 121 drives the second convex member 122 to rotate. A rotating shaft is arranged at the lower end of the upper convex block 1223, and the upper end of the lower convex block 1224 is rotatably arranged on the rotating shaft. At the same time, the other sides of the rotation points of the upper convex block 1223 and the lower convex block 1224 are in contact with each other, thereby playing a limiting role, so that the lower convex block 1224 can only rotate inward, that is, rotate towards the axis direction of the first convex member 121 and cannot rotate outward. First concave surfaces and second concave surfaces are respectively arranged on their joint surfaces. When the upper convex block 1223 and the lower convex block 1224 are in contact with each other, that is, the first concave surface and the second concave surface are combined to form a complete forming groove 1222. An insertion groove 1221 is formed on the upper convex block 1223. A first sliding member 124 is arranged in the insertion groove 1221 in a guiding and sliding manner. One end of a first elastic member 1241 abuts against the rear end of the first sliding member 124, and the other end abuts against the inner wall of the sliding cavity. A second sliding member 125 is arranged in the lower end surface of the upper convex block 1223 in a guiding and sliding manner. One end of a second elastic member 1251 abuts against the rear end of the second sliding member 125, and the other end abuts against the rear wall of the sliding cavity of the second sliding member 125. At the same time, one end of a first pull rope 126 is connected to the rear end of the first sliding member 124, and the other end is connected to the rear end of the second sliding member 125. The elastic force of the first elastic member 1241 is greater than the elastic force of the second elastic member 1251.

[0032] When the first sliding member 124 is not pressed, the first pull rope 126 is in a tensioned state. At the same time, the second sliding member 125 is located in the upper convex block 1223, and the bottom end does not extend beyond the lower end surface of the upper convex block 1223. When the first sliding member 124 is pressed, that is, when an object is inserted into the insertion groove 1221, the first sliding member 124 slides backward, thereby relaxing the first pull rope 126. The second sliding member 125 extends downward under the action of the second elastic member 1251. A locking hole 1225 is formed on the upper end surface of the lower convex block 1224. The second sliding member 125 extends downward and is inserted into the locking hole 1225, so that the lower convex block 1224 cannot rotate, that is, the lower convex block 1224 is locked.

[0033] The lower convex block 1224 is divided into a first lower convex block 1227 and a second lower convex block 1228. The first lower convex block 1227 is in contact connection with the upper convex block 1223, and the second lower convex block 1228 is arranged on the bottom surface of the first lower convex block 1227 with upper and lower limit guiding sliding. In the initial state, there is a clearance groove 1229 between the first lower convex block 1227 and the second lower convex block 1228. A first locking member 123 is arranged on the first convex member 121. The first locking member 123 includes a sliding pin 1231, a fifth elastic member 1232 and a second electromagnet 1233. A sliding pin cavity is formed on the side wall of the first convex member 121. The second electromagnet 1233 is arranged on the rear end wall of the sliding pin cavity. The sliding pin 1231 is arranged in the sliding pin cavity with guiding sliding. The fifth elastic member 1232 is arranged in the sliding pin cavity. One end of the fifth elastic member 1232 abuts against the limiting block of the sliding pin 1231, and the other end abuts against the second electromagnet 1233. The limiting block at the rear end of the sliding pin 1231 is made of magnetic pole material. In the initial state, under the action of the fifth elastic member 1232, the front end of the sliding pin 1231 extends out of the sliding pin cavity. After the first convex member 121 and the second convex member 122 are combined, the clearance groove 1229 is located at the front end of the sliding pin 1231. At the same time, the height of the clearance groove 1229 is consistent with the height of the sliding pin 1231. When the sliding pin 1231 extends forward, it is inserted into the clearance groove 1229, thereby locking the lower convex block 1224, and further locking the second convex block 122 on the first convex member 121. After the second electromagnet 1233 is powered on, the sliding pin 1231 is adsorbed backward, so that the sliding pin 1231 retracts into the sliding pin cavity, and then the second convex block 122 is unlocked.

[0034] The roll pressing member 2 includes a guide rail 21, a rotating frame 22 and a sliding frame 23. The guide rail 21 is arranged on the equipment bottom plate. The guide rail 21 is a circular rail, and its rotation axis is consistent with the axis of the forming concave die 13. The rotating frame 22 is slidably arranged on the guide rail 21, so that the rotating frame 22 can rotate around the forming concave die 13. A sliding groove 221 is arranged on the rotating frame 22, and the direction of the sliding groove 221 faces the axis direction of the forming concave die 13. The sliding frame 23 is arranged in the sliding groove 221 in a limited and guided manner. A fourth elastic member 222 is arranged in the sliding groove 221. The two ends of the fourth elastic member 222 respectively abut against the front end of the sliding frame 23 and the front end face of the sliding groove 221. An electromagnet 231 is arranged at the upper end of the sliding frame 23. A roller frame 232 is arranged in the middle position of the sliding frame 23 in a guided and sliding manner. At the same time, the front end of the roller frame 232 is arranged in the guide cavity 1321 in a guided and sliding manner. A roller 2321 is rotatably arranged at the front end of the roller frame 232. A third elastic member 2322 is sleeved on the roller frame 232, and its two ends respectively abut against the front end of the roller frame 232 and the sliding frame 23. When the roller frame 232 moves towards the axis of the forming concave die 13, it can abut against the outer wall of the formed part. A braking member is arranged on the rotating frame 22. When the electromagnet 231 is energized, the braking member is closed, so that the rotating frame 22 can slide on the guide rail 21. After the electromagnet 231 is powered off, the braking member is activated to lock the rotating frame 22 on the guide rail 21 to prevent it from moving.

[0035] Its working principle or usage method is as follows:

[0036] In the initial state, the first convex member 121 and the second convex member 122 are combined to form a complete forming convex die 12. At this time, the sliding pin 1231 extends forward under the action of the fifth elastic member 1232 and is inserted into the clearance groove 1229 to lock the second convex member 122 on the first convex member 121. At this time, the formed sheet is placed on the forming concave die 13, and the pressing member 11 moves downward. The forming convex die 12 and the forming concave die 13 cooperate to punch and form a straight-barrel cookware. At this time, the insertion groove 1221 on the convex block 1223 is aligned with the electromagnet 231 at the upper end of the sliding frame 23. A magnetic attracting member is arranged on the bottom surface of the insertion groove 1221. At this time, the electromagnet 231 is energized. Under the action of the magnetic force, the sliding frame 23 slides in the sliding groove 221, and the electromagnet 231 is sucked into the insertion groove 1221 and adsorbed on the bottom surface of the insertion groove 1221. After the electromagnet 231 is energized, the second electromagnet 1233 is also energized at the same time to adsorb and retract the sliding pin 1231 into the sliding pin cavity, unlocking the second convex block 122. At this time, the pressing member 11 moves upward, driving the first convex member 121 to move upward and leave the forming concave die 13 and then stop rising. After the second convex member 122 is inserted by the electromagnet 231, it cannot move upward, so it remains stationary.

[0037] When the electromagnet 231 is inserted into the insertion slot 1221, the roller 2321 elastically abuts against the outer wall of the formed cookware. At the same time, when the electromagnet 231 is inserted into the insertion slot 1221, it presses against the first sliding member 124. The first sliding member 124 slides backward, loosening the first pulling rope 126. The second sliding member 125 extends downward under the action of the second elastic member 1251 and is inserted into the locking hole 1225, thereby locking the lower convex block 1224 and preventing the lower convex block 1224 from rotating. After the upper convex block 1223 and the lower convex block 1224 are combined, a complete formed groove 1222 is formed. And the formed groove 1222 and the roller 2321 are at the same height. At the same time, due to the withdrawal of the sliding pin 1231, the second lower convex block 1228 can move upward.

[0038] At this time, the rotating disk 1112 rotates to drive the first convex member 121 to rotate. And the electromagnet 231 is inserted into the insertion slot 1221, so that the sliding frame 23 and the second convex member 122 form a whole. Therefore, when the first convex member 121 drives the second convex member 122 to rotate, it drives the sliding frame 23 to rotate, and then the formed groove 1222 and the roller 2321 rotate synchronously. Under the action of the third elastic member 2322, the roller 2321 gradually approaches the rotation axis, so as to cooperate with the formed groove 1222 to form an inner groove opening on the formed cookware, thus completing the grooving work on the formed cookware. During the rolling process, the friction between the outer wall of the formed cookware and the bottom cavity 131 prevents the formed cookware from moving.

[0039] After the grooving work is completed, the rotating disk 1112 stops rotating, and the electromagnet 231 is powered off. The sliding frame 23 moves toward the rear end of the sliding slot 221 under the action of the fourth elastic member 222, so that the electromagnet 231 leaves the insertion slot 1221. At the same time when the electromagnet 231 leaves the insertion slot 1221, the pressure on the first sliding member 124 disappears. The first sliding member 124 extends forward under the action of the first elastic member 1241, thereby pulling the first pulling rope 126, causing the second sliding member 125 to leave the locking hole 1225 and retract into the bottom surface of the upper convex block 1223, thus unlocking the lower convex block 1224. The lower convex block 1224 can rotate. After the electromagnet 231 completely leaves, the limiting effect of the electromagnet 231 on the upper convex block 1223 disappears. The upper convex block 1223 moves upward under the action of the elastic rope 1213 and is combined with the first convex member 121 again. After resetting, the second electromagnet 1233 is powered off, and the sliding pin 1231 is inserted into the clearance slot 1229 again under the action of the fifth elastic member 1232 to lock the second convex member 122 on the first convex member 121. At this time, the pressing member 11 rises a certain height again, so that there is a certain height between the formed punch 12 and the formed die 13, enabling the formed cookware to be taken out of the formed die 13.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
