Due to the complex internal structure of the left and right side panels of the backrest, multiple sets of punching machines are used in conjunction during the stamping operation, and the transfer operation of the left and right side panels of the backrest needs to be completed manually. The shaping machine processing cannot be completed at one time by a single device, which reduces its processing efficiency; secondly, when a continuous stamping structure is adopted, the material will be embedded with the mold after each stamping operation, and the mold cannot completely complete the material separation operation during the separation process, making it impossible for the material to proceed to the next step of stamping and shaping, which reduces its continuous stamping effect and does not have an auxiliary separation structure; at the same time, different types of left and right side panels of the backrest have different sizes, and the above-mentioned equipment cannot flexibly adapt to the material processing of left and right side panels of the backrest with different specifications, which reduces its flexibility in use. Summary of the invention

[0006] The problem to be solved by the present invention is:

[0007] 1. Due to the complex internal structure of the left and right side panels of the backrest, multiple sets of punching machines are used in conjunction during the stamping operation, and the transfer operation of the left and right side panels of the backrest needs to be completed manually. The shaping machine processing cannot be completed at one time by a single device, which reduces its processing efficiency;

[0008] 2. Secondly, when the continuous stamping structure is adopted, the material will be embedded with the mold after each stamping operation. The mold cannot completely complete the material separation operation during the separation process, making it impossible for the material to proceed to the next step of stamping and shaping, reducing its continuous stamping effect and having no auxiliary separation structure;

[0009] 3. At the same time, different types of left and right side panels of the backrest have different sizes, and the above equipment cannot be flexibly applied to the material processing of the left and right side panels of the backrest with different specifications, which reduces its flexibility in use.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] A production process for left and right side panels of a backrest, comprising the following steps:

[0013] Step 2: Move the material plate between the lower mold and the upper mold, and use the downward movement of the upper mold to cooperate with the lower mold to complete the shaping operation of the structural groove in the backrest side plate on the material plate;

[0014] Step three, when the upper mold moves up, the ejector frame is used in conjunction with the moving ejector head to complete the separation operation between the backrest side plate and the upper mold, and at the same time, the lower ejector rod is used in conjunction with the lifting push plate to eject the lower ejector column upward to complete the separation operation between the lower mold and the backrest side plate.

[0015] A production equipment for left and right side panels of a backrest, comprising a lower mold, an upper mold and a feed base, wherein a plurality of groups of lower molds are arranged on the inner side of the upper end of the feed base, and a plurality of groups of upper molds are arranged on the inner side of the upper end of the feed base above the lower mold, the inner surface of the feed base is located on both sides of the lower mold and is provided with a positioning seat and a ejecting member, the positioning seat and the ejecting member are arranged side by side, a driver is arranged at the upper end of the upper mold, and two groups of movable side panels are movably installed on the inner side of the positioning seat, and the two groups of movable side panels are symmetrically arranged.

[0016] As a further technical solution of the present invention, the upper mold part includes an upper mold and a stamping plate. The upper mold is spliced ​​and installed in the middle position of the lower end of the stamping plate. The lower end of the stamping plate is located on the outside of the upper mold and is elastically installed with a ejection frame. The upper end of the stamping plate is driven by a lifting rod. The stamping plate and the ejection frame are elastically connected by a spring. When the stamping plate completes the stamping and shaping of the structural groove and moves upward, the spring is used to eject the ejection frame downward, so that the ejection frame pushes the material plate downward, and the upper end of the backrest side panel is moved out of the upper mold.

When the demolding operation of the backrest side panels is performed, the ejection frame is affected by the positions of different types of structural grooves, so that the backrest side panels and the upper mold cannot be completely separated when in use. The position of the movable ejector can be adjusted in both directions by using the movable cross bars, so that the movable ejector moves to the structural groove, and the structural groove of the backrest side panels can be accurately separated when the demolding operation is performed.

[0019] As a further technical solution of the present invention, a lifting block is movably installed on the inner side of the lifting member, and a roller is movably installed on the upper end of the lifting block. The lifting member and the lifting block are driven by a pneumatic lift rod, and the movement of the material plate on the feeding base allows the material plate to pass through several groups of lower molds and upper molds to finally complete the stamping and shaping of the backrest side panels. After completing one stamping, the material plate of the backrest side panels needs to move forward one station to perform the stamping operation of the next structural groove. The pneumatic lift rod is used to drive the lifting block to move upward, and the rotation of the roller can be used to move the material plate forward and complete the conveying operation of the material plate.

[0020] As a further technical solution of the present invention, a connecting pipe is provided on the side of the pneumatic ejector rod, two sets of lifting guide rods are provided on the lower end of the lifting ejector block, and a sliding groove is provided on the side of the ejector member for use with the lifting ejector block.

[0022] As a further technical solution of the present invention, the lower mold component includes a lower push column and a lower mold. The lower push column is movably sleeved on the inner side of the lower mold. The lower end of the lower push column is driven by a lower push rod. The lower push rod is used to drive the lower push column to move upward, so that the lower push column can move the material plate forward to complete the separation operation of the lower mold and the backrest side panel.

[0023] As a further technical solution of the present invention, the outer surface of the lower push column is sleeved with a limiting plate, the lower end of the limiting plate and the lower push rod are connected and fixed by a lifting push plate, and the outer surface of the limiting plate is provided with a fastening bolt. The user can use the limiting plate to adjust the use length of the lower push column according to the depth of the backrest side panel.

[0024] Beneficial effects of the present invention:

[0025] 1. By setting up several groups of lower molds and upper molds, when the left and right side panels of the backrest are used, the production equipment has a continuous stamping and shaping structure, which can continuously complete the stamping and shaping of the left and right side panels of the backrest during the material conveying process, thereby improving its processing efficiency;

[0026] During operation, the material plate is placed on the material feeding base of the processing equipment, and the lateral push rod is used to drive the moving side plate according to the width of the material plate, so that the two groups of moving side plates are stuck on the sides of the material plate, and the rotation of the roller is used to drive the material plate to move. Several groups of lower molds and upper molds are installed on the material feeding base, and each group of lower molds and upper molds corresponds to a structural groove of a structure. In the process of material plate conveying, the stamping and shaping of all structural grooves can be completed. The user moves the material plate between the lower mold and the upper mold, and drives the punching plate with the lifting rod so that the punching plate drives the upper mold to move downward, and the upper mold cooperates with the lower mold to complete the stamping and shaping of the structural groove. After the stamping of a structural groove is completed, the material plate needs to move forward as a whole by one station, and the movement operation of the material plate can be completed by using the ejecting piece, and the pneumatic ejector rod is used to drive the lifting ejector block to move upward, and the upward lifting ejector block can lift the material plate as a whole, so that the material plate is placed above the lower mold, and the rotation of the roller driven by the motor can move the material plate forward and complete the conveying operation of the material plate.

[0027] 2. By setting the ejector frame and the lower ejector column, when the left and right side panels of the backrest are used, the upper and lower mold auxiliary demoulding structure is provided, the use of several groups of lower molds and upper molds is optimized, and the stability of the left and right side panels of the backrest is improved during the processing operation;

[0028] When in use, when the stamping plate moves upward after completing the stamping and shaping of the structural groove, the spring is used to push the ejection frame downward, so that the ejection frame pushes the material plate downward, and the upper end of the backrest side plate is moved out of the upper mold. When the backrest side plate is demoulded, the ejection frame cannot complete the local force at the structural groove due to the position of different types of structural grooves, so that the ejection frame cannot completely separate the backrest side plate and the upper mold when in use. The position of the moving ejector head can be adjusted in both directions by using the moving cross bar, so that the moving ejector head can be moved to the structural groove. When performing the demoulding operation, the structural grooves of the backrest side panels are accurately separated, and the position of the moving cross bar in the ejector frame is adjusted. The moving ejector head is moved at the lower end of the moving cross bar to complete the two-way position adjustment of the moving ejector head. At the same time, the moving cross bar and the moving ejector head can be locked and fixed by rotating the threaded sleeve. Secondly, the lower ejector rod is used to drive the lower ejector column to move upward, so that the lower ejector column can move the material plate forward, completing the separation operation of the lower mold and the backrest side panel, so that the backrest side panel is completely separated from the lower mold and the upper mold, thereby improving its processing effect.

[0029] 3. By setting a positioning card seat, when the left and right side panel production equipment of the backrest is used, it can be flexibly applied to materials of different specifications, thereby improving its flexibility in use;

[0030] During operation, because the material plate moves on the inner side of the feeding base, the positioning base can be adaptively adjusted according to the width of the material plate. The air inlet nozzle and the tapping hose can be used to simultaneously control the two sets of movable side plates through the pneumatic principle, and the position between the two sets of movable side plates can be adjusted so that the two sets of movable side plates can fix the material plate of fixed width. In the limited state, the material plate is centered between the lower mold and the upper mold, which improves the processing accuracy of the material plate while meeting the conveying operation of material plates of different sizes.

DETAILED DESCRIPTION

[0041] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0042] like Figure 1 As shown, a production process for left and right side panels of a backrest includes the following steps:

[0043] Step 1: Place the material plate 31 on the material feeding base 3 of the processing equipment, and use the lateral push rod 21 to drive the movable side plate 19 according to the width of the material plate 31, so that the two sets of movable side plates 19 are clamped on the side of the material plate 31, and the material plate 31 is driven to move by the rotation of the roller 20;

[0044] Step 2: Move the sheet 31 between the lower mold 1 and the upper mold 2, and use the upper mold 2 to move downward, and the upper mold 8 cooperates with the lower mold 30 to complete the shaping operation of the structural groove 33 in the backrest side plate 32 on the sheet 31, such as Figure 8 As shown;

[0045] Step three, when the upper mold 2 moves upward, the ejector frame 7 is used in conjunction with the moving ejector head 23 to complete the separation operation between the backrest side plate 32 and the upper mold 8, and at the same time, the lower ejector rod 26 is used in conjunction with the lifting push plate 27 to eject the lower ejector column 29 upward to complete the separation operation between the lower mold 30 and the backrest side plate 32.

[0046] To solve the problem of continuous stamping of the left and right side panels of the backrest, Figure 2 As shown, the production equipment for the left and right side panels of the backrest includes a lower mold 1, an upper mold 2 and a feeding base 3, a plurality of groups of lower molds 1 are arranged on the inner side of the upper end of the feeding base 3, and a plurality of groups of upper molds 2 are arranged on the inner side of the upper end of the feeding base 3 located above the lower mold 1, the inner surface of the feeding base 3 is located on both sides of the lower mold 1 and is provided with a positioning card seat 4 and a lifting member 5, the positioning card seat 4 and the lifting member 5 are arranged side by side, a driver 6 is arranged on the upper end of the upper mold 2, and two groups of movable side panels 19 are movably installed on the inner side of the positioning card seat 4, and the two groups of movable side panels 19 are symmetrically arranged.

[0047] To solve the demoulding problem of the left and right side panels of the backrest, Figure 2 As shown, the upper mold 2 includes an upper mold 8 and a stamping plate 11. The upper mold 8 is spliced ​​and installed in the middle position of the lower end of the stamping plate 11. The lower end of the stamping plate 11 is located on the outer side of the upper mold 8 and is elastically installed with a ejection frame 7. The upper end of the stamping plate 11 is driven by a lifting rod 12. The stamping plate 11 and the ejection frame 7 are elastically connected by a spring 10. When the stamping plate 11 completes the stamping and shaping of the structural groove 33 and moves upward, the spring 10 is used to eject the ejection frame 7 downward, so that the ejection frame 7 pushes the material plate 31 downward, and the upper end of the backrest side plate 32 is moved out of the upper mold 8.

[0048] like Figure 6 As shown, two groups of movable cross bars 9 are movably installed on the inner side of the ejection frame 7, and the two ends of the movable cross bars 9 are movably connected to the ejection frame 7 through docking slide buckles 22, and two groups of movable ejectors 23 are movably installed on the lower end of the movable cross bars 9. When the backrest side panels 32 are demolded, the ejection frame 7 is affected by the positions of different types of structural grooves 33, so that the backrest side panels 32 and the upper mold 8 cannot be separated when in use. The movable cross bars 9 can be used to adjust the positions of the movable ejectors 23 in both directions, so that the movable ejectors 23 are moved to the structural grooves 33. When the demolding operation is performed, the structural grooves 33 of the backrest side panels 32 can be accurately separated.

[0049] like Figure 6 As shown, the ends of the movable cross bar 9 and the movable top head 23 are movably connected via a docking slide 25, and a threaded sleeve 24 is movably mounted on the outer surface of the movable top head 23. The position of the movable cross bar 9 in the ejection frame 7 is adjusted, and the position of the movable top head 23 at the lower end of the movable cross bar 9 is moved, thereby completing the bidirectional position adjustment of the movable top head 23. At the same time, the movable cross bar 9 and the movable top head 23 can be locked and fixed by rotating the threaded sleeve 24.

[0050] like Figure 4As shown, a lifting ejector block 16 is movably installed on the inner side of the ejector member 5, and a roller 15 is movably installed on the upper end of the lifting ejector block 16. The ejector member 5 and the lifting ejector block 16 are driven by a pneumatic ejector rod 13. The material sheet 31 moves on the feed base 3, so that the material sheet 31 passes through several groups of lower molds 1 and upper molds 2, and finally completes the stamping and shaping of the backrest side plate 32. After completing one stamping, the material sheet 31 of the backrest side plate 32 needs to move forward one station to perform the stamping operation of the structural groove 33 of the present embodiment. The pneumatic ejector rod 13 is used to drive the lifting ejector block 16 to move upward, and the roller 15 is rotated to lift the material sheet 31 upward, and the conveying operation of the material sheet 31 is completed.

[0051] A connecting pipe is provided on the side of the pneumatic ejector rod 13 , two sets of lifting guide rods 14 are provided on the lower end of the lifting ejector block 16 , and a sliding groove used in conjunction with the lifting ejector block 16 is provided on the side of the ejector member 5 .

[0052] To solve the processing problem of left and right side panels of backrests of different sizes, such as Figure 5 As shown, the positioning base 4 and the movable side plate 19 are movably connected via a transverse push rod 21, an air inlet nozzle 17 is fixedly installed at the middle position of the lower end of the positioning base 4, and the air inlet nozzle 17 and the transverse push rod 21 are connected via a branch hose 18. The air inlet nozzle 17 and the branch hose 18 can be used to simultaneously control the two groups of movable side plates 19 through the pneumatic principle, and the position between the two groups of movable side plates 19 can be adjusted so that the two groups of movable side plates 19 can fix the material plate 31 of a fixed width.

[0053] like Figure 7 As shown, the lower mold 1 includes a lower push column 29 and a lower mold 30. The lower push column 29 is movably sleeved on the inner side of the lower mold 30. The lower end of the lower push column 29 is driven by the lower push rod 26. The lower push rod 26 is used to drive the lower push column 29 to move upward, so that the lower push column 29 can lift the material plate 31 upward to complete the separation operation of the lower mold 30 and the backrest side plate 32.

[0054] The outer surface of the lower push column 29 is sleeved with a limit plate 28, and the lower end of the limit plate 28 and the lower push rod 26 are connected and fixed by a lifting push plate 27. The outer surface of the limit plate 28 is provided with a fastening bolt. The user can use the limit plate 28 to adjust the usable length of the lower push column 29 according to the depth of the backrest side plate 32.

[0055] During use, due to the complex structure of the left and right side panels of the backrest, multiple sets of punching machines are used in cooperation during the stamping operation, and the transfer operation of the left and right side panels of the backrest needs to be completed manually. The shaping machine processing cannot be completed at one time by a single device, which reduces its processing efficiency;

[0056] To this end, by setting up a plurality of groups of lower molds 1 and upper molds 2, when the left and right side panels of the backrest are used, the equipment has a continuous stamping and shaping structure, and the stamping and shaping of the left and right side panels of the backrest can be continuously completed during the material conveying process, thereby improving its processing efficiency;

[0057] During operation, the material plate 31 is placed on the feeding base 3 of the processing equipment, and the lateral push rod 21 is used to drive the movable side plate 19 according to the width of the material plate 31, so that the two groups of movable side plates 19 are clamped on the side of the material plate 31, and the rotation of the roller 20 is used to drive the material plate 31 to move. A plurality of groups of lower molds 1 and upper molds 2 are installed on the feeding base 3, and each group of lower molds 1 and upper molds 2 corresponds to a structural groove 33 of a structure. During the conveying process of the material plate 31, the stamping and shaping of all the structural grooves 33 can be completed. The user moves the material plate 31 between the lower mold 1 and the upper mold 2, and uses the lifting rod 12 to drive the stamping The plate 11 is driven by the stamping plate 11 to drive the upper mold 8 to move downward, and the upper mold 8 cooperates with the lower mold 30 to complete the stamping and shaping of the structural groove 33. After the stamping of a structural groove 33 is completed, the material plate 31 needs to be moved forward by one station as a whole. The material plate 31 can be moved forward by using the ejector 5, and the pneumatic ejector 13 is used to drive the lifting ejector block 16 to move upward. The upward lifting ejector block 16 can lift the material plate 31 as a whole, so that the material plate 31 is placed above the lower mold 30. With the rotation of the motor-driven roller 15, the material plate 31 can be moved forward and the conveying operation of the material plate 31 is completed.

[0058] Secondly, when the continuous stamping structure is adopted, the material will be embedded with the mold after each stamping operation. The mold cannot completely complete the material separation operation during the separation process, making it impossible for the material to proceed to the next step of stamping and shaping, reducing its continuous stamping effect and having no auxiliary separation structure;

[0059] To this end, by setting the ejector frame 7 and the lower ejector column 29, when the backrest left and right side panel production equipment is used, it has an upper and lower mold auxiliary demoulding structure, optimizes the use of several groups of lower molds 1 and upper molds 2, and improves the stability of the backrest left and right side panel processing operation;

[0060] When in use, when the stamping plate 11 moves upward after completing the stamping and shaping of the structural groove 33, the spring 10 is used to push the ejection frame 7 downward, so that the ejection frame 7 pushes the material plate 31 downward, and the upper end of the backrest side plate 32 is moved out of the upper mold 8. When the backrest side plate 32 is demoulded, the ejection frame 7 is unable to complete the local force at the structural groove 33 due to the position of different types of structural grooves 33, so that the ejection frame 7 cannot completely separate the backrest side plate 32 and the upper mold 8 when in use. The movable cross bar 9 can be used to adjust the position of the movable ejector 23 in both directions, so that the movable ejector 23 moves to the structural groove 33. During the demoulding operation, the structural groove 33 of the backrest side plate 32 is accurately separated, and the position of the movable cross bar 9 in the ejection frame 7 is adjusted, and the position of the movable ejector head 23 at the lower end of the movable cross bar 9 is moved, so as to complete the two-way position adjustment of the movable ejector head 23. At the same time, the threaded sleeve 24 can be rotated to lock and fix the movable cross bar 9 and the movable ejector head 23. Then, the lower ejector rod 26 is used to drive the lower ejector column 29 to move upward, so that the lower ejector column 29 can move the material plate 31 forward, and the separation operation of the lower mold 30 and the backrest side plate 32 is completed, so that the backrest side plate 32 is completely separated from the lower mold 30 and the upper mold 8, thereby improving its processing effect.

[0061] At the same time, different types of backrest left and right side panels have different sizes, and the above equipment cannot be flexibly applied to the material processing of backrest left and right side panels of different specifications, which reduces its flexibility in use;

[0062] To this end, by providing a positioning card seat 4, when the left and right side panels of the backrest are used, the production equipment can be flexibly adapted to materials of different specifications, thereby improving its flexibility in use;

[0063] During operation, because the material sheet 31 moves on the inner side of the feeding base 3, the positioning base 4 can be adaptively adjusted according to the width of the material sheet 31, and the air inlet nozzle 17 and the branch hose 18 can be used to simultaneously control the two groups of movable side plates 19 through the pneumatic principle, and adjust the position between the two groups of movable side plates 19 so that the two groups of movable side plates 19 can fix the material sheet 31 of fixed width. In the limited state, the material sheet 31 is centered between the lower mold 1 and the upper mold 2, which improves the processing accuracy of the material sheet 31 while meeting the conveying operation of material sheets 31 of different sizes.

[0064] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
