Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and particularly relates to a device and a processing method for thickening the side wall of a notebook computer housing. Background Art

[0002] For a notebook computer housing made of metal, in order to increase the support strength of the side plate of the housing, the side plate of the housing is thickened by stamping.

[0003] For example, the existing patent with the application number CN201921223633.3, the publication (announcement) number CN210498186U, and the name "Metal Notebook Housing Piercing and Extrusion Die" discloses "a lower die and an upper die. The lower die includes a floating lower support plate for supporting the inside of the housing, a lower punch for flattening the vertical surface of the housing, a floating wedge block, and a side abutting block that moves horizontally relative to the lower support plate under the drive of the wedge block; the upper die includes an upper pressing block for pressing the plate surface of the housing and a side pressing block that can move horizontally relative to the upper pressing block. The side pressing block moves close to the upper pressing block under the drive of the side abutting block. Through piercing and extrusion, the bent vertical surface is thickened and shortened, realizing the processing of a notebook housing with a thicker vertical surface than the plate surface."

[0004] The applicant found in the actual processing process that the above-mentioned patent-provided metal notebook housing piercing and extrusion die and the existing technologies all have the same drawbacks: Since the side plate of the housing needs to be limited by a side abutting block as in the above-mentioned patent during the thickening process to prevent the side plate from cracking or having an excessive thickening thickness during the thickening process, it is precisely because of the existence of the side abutting block that after the side plate of the housing is thickened between the side abutting block and the lower support plate, a large extrusion force will be generated with the side abutting block and the lower support plate, resulting in the thickened side plate of the housing being firmly squeezed by the side abutting block and the lower support plate, thus making it difficult to take out the housing. In the above-mentioned patent, although the side plate of the housing can be stably thickened by relying on the limitation of the side abutting block on the side plate of the housing, after thickening, due to the increase in thickness, a strong extrusion force is generated between the side plate of the housing and the side abutting block and the lower support plate. It is difficult to move the floating wedge block upward only by the elastic force of the floating wedge block, and then it is difficult to separate the side abutting block from the housing, and it is even more impossible to loosen between the side plate of the housing and the lower support plate, resulting in the housing being firmly clamped and difficult to remove. Obviously, limiting the side plate of the housing and easily removing the housing are a pair of contradictory problems. Therefore, it is an urgent technical problem to be solved how to limit the side plate of the housing by the side abutting block to obtain stable thickening during the thickening of the side plate of the housing, and how to prevent the side plate of the housing from being clamped by the side abutting block and the lower support plate after the thickening of the side plate of the housing is completed, and how to loosen between the side plate of the housing and the lower support plate to facilitate the removal of the housing. Summary of the Invention

[0005] The object of the present invention is to provide a device and a processing method for thickening the side wall of a notebook computer housing to solve the above deficiencies in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solution: A device for thickening the side wall of a notebook computer housing, including an upper die base and a lower die base arranged up and down, a driving mechanism is connected to the upper die base, and further includes:

[0007] A lower support plate, which is vertically elastically slidably arranged in the lower die base for placing the housing;

[0008] Two pier blocks symmetrically arranged and vertically slidably arranged in the lower die base, the lower support plate is located between the two pier blocks, and the left side plate and the right side plate of the housing are respectively abutted against the two pier blocks;

[0009] Two push-pull plates symmetrically arranged and horizontally elastically slidably arranged in the lower die base, and the two push-pull plates are respectively linked with the two pier blocks through linkage components;

[0010] Two side abutting blocks symmetrically arranged and horizontally slidably clamped under the upper die base, the two side abutting blocks are located outside the two pier blocks and are respectively lapped and matched with the two pier blocks, and the two push-pull plates are located outside the two side abutting blocks and are respectively vertically slidably clamped with the two side abutting blocks;

[0011] After the thickening is completed, during the process of the driving mechanism driving the upper die base to move upward, the two side abutting blocks are pulled upward to be respectively lapped with the two pier blocks to drive the two pier blocks to move upward. The upward movement of the two pier blocks loosens the space between the housing and the lower support plate, and at the same time drives the two push-pull plates to slide through the linkage components to separate from the side plates of the housing.

[0012] For the above device for thickening the side wall of a notebook computer housing, a limiting block is fixedly arranged on the pier block, an inner groove corresponding to the limiting block is opened on the side abutting block, the limiting block is inserted into the corresponding inner groove, and the lapping of the side abutting block and the pier block is realized by the abutting of the bottom of the limiting block and the bottom of the inner groove.

[0013] For the above device for thickening the side wall of a notebook computer housing, a set of tension springs are fixedly installed between the two push-pull plates and the inner wall of the lower die base. Based on the elastic force of the tension springs, a gap is formed between the bottom of the pier block and the bottom of the inner cavity of the lower die base in the initial state. During thickening, when the driving mechanism drives the upper die base to move downward, the upper die base presses the housing to push the two pier blocks to move downward to the limit state, and the two pier blocks respectively abut against the two side abutting blocks through the linkage components to limit the left and right side plates of the housing.

[0014] The above-mentioned laptop computer housing side wall thickening device, when the housing is placed on the lower support plate, and there is a space between the bottom surface of the top plate of the housing and the top surface of the lower support plate while the bottoms of the left and right side plates of the housing are in one-to-one correspondence with the tops of the two thickening blocks, during the process of the two thickening blocks being pressed and moved downward by the upper die holder, the bottom surface of the top plate of the housing is made to fit with the top surface of the lower support plate so that the top plate of the housing does not hang in the air when the left and right side plates of the housing are thickened.

[0015] The above-mentioned laptop computer housing side wall thickening device, the linkage member includes a swing plate, lower abutting rods and upper abutting rods are arranged at both ends of the swing plate in one-to-one correspondence, a rotating shaft located between the lower abutting rod and the upper abutting rod and rotatably connected to the lower die holder is further arranged on the swing plate, a horizontal sliding hole for the lower abutting rod to slide and insert is formed on the thickening block, an inner sliding groove for the upper abutting rod to slide and insert is formed on the push-pull plate, when the thickening block moves, the swing plate is driven to rotate through the lower abutting rod, and the push-pull plate is driven to slide through the upper abutting rod.

[0016] The above-mentioned laptop computer housing side wall thickening device, two support plates corresponding to the two push-pull plates are fixedly arranged in the lower die holder, the top of the support plate is in sliding abutment with the bottom of the push-pull plate, a locking rod slidably inserted with the push-pull plate is fixedly installed on the side abutting block through a fixing plate, a locking hole for the locking rod to insert is formed on the support plate, when the side abutting block abuts against the thickening block, the locking rod and the locking hole are coaxial, and as the locking rod continues to move downward, the locking rod is inserted into the corresponding locking hole to lock the side abutting block.

[0017] The above-mentioned laptop computer housing side wall thickening device, two guide rails arranged front and back relatively are fixedly arranged on the side surface of the side abutting block, and two T-shaped sliding plates slidably inserted with the two guide rails in one-to-one correspondence are fixedly arranged on the side surface of the push-pull plate.

[0018] The above-mentioned laptop computer housing side wall thickening device, two accommodating grooves corresponding to the two guide rails and penetrating the bottom of the side abutting block are formed in the side abutting block, oil-absorbing cotton is filled in the accommodating grooves, a plugging block is inserted into the bottom of the accommodating groove, and the accommodating groove is communicated with the guide rail through a penetration hole formed on the side abutting block.

[0019] The above-mentioned laptop computer housing side wall thickening device, a ejector rod corresponding to the plugging block is fixedly arranged in the lower die holder, during the process of the side abutting block moving downward, the ejector rod presses the corresponding plugging block to compress the oil-absorbing cotton so that the oil liquid is smeared between the T-shaped sliding plate and the guide rail through the penetration hole.

[0020] A processing method for thickening the side wall of a laptop computer housing, which is based on the above-mentioned laptop computer housing side wall thickening device, includes the following steps:

[0021] S1: Feeding: Place the housing on the lower platen so that the left and right plates of the side abutting block are respectively and correspondingly abutted against the tops of the two pier blocks.

[0022] S2: Limiting the side plates of the housing: The driving mechanism drives the upper die base to move downward. During the downward movement of the upper die base, it squeezes the housing and drives the two pier blocks to move downward to the limit state through the housing. During the process of the two pier blocks moving downward to the limit state, they push the corresponding two push-pull plates to elastically slide through the linkage member, thereby driving the two side abutting blocks to respectively and correspondingly abut against the two pier blocks to limit the left and right side plates of the housing.

[0023] S3: Locking the side abutting block: When the side abutting block abuts against the pier block, the locking rod fixedly connected to the side abutting block is coaxial with the locking hole on the support plate. As the locking rod continues to move downward, the locking rod is inserted into the corresponding locking hole to lock the side abutting block.

[0024] S4: Piercing thickness: During the process of the locking rod being inserted into the corresponding locking hole, the upper die base continuously presses down the housing, the side abutting block, and the lower platen, and in cooperation with the two pier blocks, pierces the thickness of the left and right side plates of the housing.

[0025] S5: Taking the workpiece: After the left and right side plates of the housing are pierced in thickness, they are firmly squeezed between the side abutting block and the lower platen. During the process of driving the upper die base to move upward by the driving mechanism, the two side abutting blocks are pulled upward so that the two side abutting blocks respectively and correspondingly overlap with the two pier blocks to drive the two pier blocks to move upward. The upward movement of the two pier blocks loosens the housing and the lower platen, and at the same time drives the two push-pull plates to slide through the linkage member to separate from the side plates of the housing, and finally the housing can be taken off.

[0026] In step S1, when the bottoms of the left and right side plates of the housing are respectively and correspondingly abutted against the tops of the two pier blocks and there is a space between the bottom surface of the top plate of the housing and the top surface of the lower platen, based on the two pier blocks being pressed down and moved by the upper die base in step S2, during the downward movement of the pier blocks, the bottom surface of the top plate of the housing fits with the top surface of the lower platen so that the top plate of the housing is not suspended when the left and right side plates of the housing are pierced in thickness.

[0027] Beneficial effects:

[0028] 1. In the above technical solution, a device and a processing method for thickening the side wall of a laptop computer housing provided by the present invention set the pier blocks in a movable form, so that the two side abutting blocks and the two pier blocks are in one-to-one lap joint during the upward movement of the upper die base. Driven by the driving mechanism, relying on the pulling force of the driving mechanism to pull the two pier blocks upward, the pulling force of the driving mechanism is sufficient to overcome the extrusion force received by the housing, so that during the upward movement, the two pier blocks push the housing upward to loosen the housing from the lower support plate, and at the same time drive the two push-pull plates to slide in the reverse direction away from the housing through the linkage, so that the two push-pull plates are separated from the left and right side plates of the housing. In this way, the side plates of the housing are not squeezed by the push-pull plates and can also be loosened from the lower support plate at the same time, killing two birds with one stone. It can be seen that the present invention can be limited by the side abutting blocks when thickening the side plates of the housing to obtain stable thickening, and can also not be clamped by the side abutting blocks and the lower support plate after the side plates of the housing are thickened, and can loosen the side plates of the housing from the lower support plate, overcoming this contradictory problem, thus facilitating the removal of the housing and effectively solving the deficiencies in the prior art;

[0029] 2. In the present invention, since the pier blocks are in a movable state, using the gap between the pier blocks and the lower die base, during the process of the pier blocks being pressed down and moved by the housing, not only can the push-pull plates be driven to elastically slide towards the housing through the linkage, so that the side abutting blocks are in contact with the pier blocks to realize the one-to-one limitation of the left and right side plates of the housing by the two side abutting blocks; but also using the gap between the pier blocks and the upper die base can make the top plate of the housing fit with the top surface of the lower support plate when the top plate of the housing is suspended when placing the housing, so that the top plate of the housing is not suspended before the side plates of the housing are thickened. Therefore, when pressing, there will be no inward protrusion or even breakage of the part of the side plate of the housing between the top plate of the housing and the top of the lower support plate. It can be seen that using the gap between the pier blocks and the upper die base plays two uncorrelated roles and produces unexpected technical effects;

[0030] 3. Furthermore, during the downward movement of the upper die base, after the side abutting blocks are in contact with the pier blocks, the locking rod can be driven to insert into the corresponding lock hole to lock the side abutting blocks. When thickening the side plates of the housing, the two side abutting blocks can limit the left and right side plates of the housing more stably, and the locking of the side abutting blocks is automatically realized during the downward movement of the upper die base, saving the operation of locking the side abutting blocks separately and effectively improving the efficiency of thickening the housing;

[0031] 4. At the same time, during the downward movement of the upper die base of the present invention, the oil is also smeared between the T-shaped slide plate and the guide rail to reduce the sliding friction between the T-shaped slide plate and the guide rail, saving the operation of smearing the oil separately.

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] First embodiment:

[0046] As Figures 1-9 shown, a device for thickening the side wall of a notebook computer shell provided by an embodiment of the present invention includes an upper die base 11 and a lower die base 12 arranged up and down. A driving mechanism is connected to the upper die base 11, and further includes:

[0047] A lower supporting plate 1, which is vertically elastically slidably arranged in the lower die base 12 and is used for placing the shell 13;

[0048] Two pier blocks 2 symmetrically arranged and vertically slidably arranged in the lower die base 12. The lower supporting plate 1 is located between the two pier blocks 2. The left side plate and the right side plate of the shell 13 are respectively abutted against the two pier blocks 2;

[0049] Two push-pull plates 4 symmetrically arranged and horizontally elastically slidably arranged in the lower die base 12. The two push-pull plates 4 are linked with the two pier blocks 2 through linkage members respectively;

[0050] Two side abutting blocks 3 symmetrically arranged and horizontally slidably clamped under the upper die base 11. The two side abutting blocks 3 are located outside the two pier blocks 2 and are respectively lapped and matched with the two pier blocks 2. The two push-pull plates 4 are located outside the two side abutting blocks 3 and are respectively vertically slidably clamped with the two side abutting blocks 3;

[0051] After the thickening is completed, during the process of driving the upper die base 11 to move upward by the driving mechanism, the two side abutting blocks 3 are pulled upward so that the two side abutting blocks 3 are respectively lapped with the two pier blocks 2 to drive the two pier blocks 2 to move upward. The upward movement of the two pier blocks 2 pushes the shell 13 to loosen from the lower supporting plate 1 and at the same time drives the two push-pull plates 4 to slide through the linkage members to separate from the side plates of the shell 13.

[0052] The side wall thickening device of the notebook computer housing provided in this embodiment is used to thicken the left and right side plates of the notebook computer housing to increase the strength of the side plates. The words related to directions and positions involved in the present invention are relative to the attached drawings. When the left and right side plates of the housing 13 are thickened, the housing 13 forms an integrally formed top plate and two side plates. Specifically, the driving mechanism is fixedly installed on the fixed frame. The driving mechanism is a servo hydraulic cylinder. The power output shaft of the driving mechanism is fixedly connected to the center of the upper die base 11. The lower die base 12 is located below the upper die base 11. An opening is provided at the top of the lower die base 12. A set of compression springs 9 are fixedly installed in the lower die base 12. The number of a set of compression springs 9 is multiple. The top of a set of compression springs 9 is fixedly connected to the bottom of the lower support plate 1. The elastic sliding of the lower support plate 1 is realized through the elasticity of the compression springs 9. The housing 13 is placed on the lower support plate 1. Two thickening blocks 2 are used to support the left and right side plates of the housing 13. The two thickening blocks 2 are slidably arranged in the lower die base 12. Vertical sliding plates 201 are integrally provided on the front and rear side plates of the thickening block 2. Vertical sliding grooves (not shown in the figure) corresponding to the vertical sliding plates 201 are provided on the inner wall of the lower die base 12. The vertical sliding plates 201 are slidably arranged in the vertical sliding grooves. The opposite surfaces of the two thickening blocks 2 are slidably abutted against the left and right side surfaces of the lower support plate 1 in a one-to-one correspondence.

[0053] Two push-pull plates 4 are elastically slidably arranged in the lower die base 12 in the horizontal direction. Horizontal sliding plates 401 are integrally provided on the front and rear side surfaces of the push-pull plate 4. Horizontal sliding grooves (not shown in the figure) corresponding to the horizontal sliding plates 401 are provided on the inner wall of the lower die base 12. The horizontal sliding plates 401 are slidably arranged in the horizontal sliding grooves. The two push-pull plates 4 are located outside the two side abutting blocks 3 and are vertically slidably clamped with the two side abutting blocks 3 in a one-to-one correspondence, so that the push-pull plates 4 and the side abutting blocks 3 can slide relatively in the vertical direction and can be linked in the horizontal direction. The purpose is that the push-pull plates 4 and the side abutting blocks 3 can slide synchronously in the horizontal direction and can slide relatively in the vertical direction at the same time. Among them, the two push-pull plates 4 and the two thickening blocks 2 are linked by a linkage member. When the thickening block 2 moves vertically, the corresponding push-pull plate 4 can be driven to slide in the horizontal direction through the linkage member. The horizontal sliding of the push-pull plate 4 drives the side abutting block 3 to slide horizontally. A plurality of T-shaped sliders 301 are fixedly arranged in an array on the top of the side abutting block 3. T-shaped grooves 1101 corresponding to the T-shaped sliders 301 are provided at the bottom of the upper die base 11. The T-shaped sliders 301 are slidably arranged in the corresponding T-shaped grooves 1101 in the horizontal direction. The T-shaped sliders 301 and the T-shaped grooves 1101 will not disengage in the vertical direction. Therefore, when the upper die base 11 moves up and down, the two side abutting blocks 3 can be driven to move up and down synchronously. At the same time, the side abutting blocks 3 can be horizontally pushed and pulled by the push-pull plates 4 while moving up and down.

[0054] Meanwhile, the two side abutting blocks 3 are located outside the two pier blocks 2 and are in one-to-one lap joint cooperation with the two pier blocks 2. During the downward movement of the upper die base 11, the side abutting blocks 3 do not lap with the pier blocks 2. During the upward movement of the upper die base 11, the side abutting blocks 3 are driven to move synchronously, so that the side abutting blocks 3 gradually lap with the pier blocks 2. When the side abutting blocks 3 lap with the pier blocks 2, when the side abutting blocks 3 continue to be driven upward by the upper die base 11, the pier blocks 2 will be pulled to move upward synchronously.

[0055] Its working principle is as follows: First, place the housing 13 on the lower support plate 1, so that the left and right side plates of the side abutting blocks 3 are in one-to-one abutment with the tops of the two pier blocks 2. The driving mechanism drives the upper die base 11 to move downward. During the downward movement of the upper die base 11, the housing 13 is squeezed and the two pier blocks 2 are driven to move downward to the limit state through the housing 13. During the process of the two pier blocks 2 moving downward to the limit state, the corresponding two push-pull plates 4 are pushed to elastically slide through the linkage member, and then the two side abutting blocks 3 are driven to abut against the two pier blocks 2 one by one to limit the left and right side plates of the housing 13. After that, the upper die base 11 continues to move downward, and the upper die base 11 squeezes the housing 13, the side abutting blocks 3 and the lower support plate 1 to move downward, and the left and right side plates of the housing 13 are thickened by the cooperation of the two pier blocks 2. After the left and right side plates of the housing 13 are thickened, they are firmly squeezed between the side abutting blocks 3 and the lower support plate 1. Then, the driving mechanism drives the upper die base 11 to move upward. During the process of driving the upper die base 11 to move upward by the driving mechanism, the two side abutting blocks 3 are pulled upward to lap with the two pier blocks 2 one by one. After lapping, the two side abutting blocks 3 drive the two pier blocks 2 to move upward synchronously. The upward movement of the two pier blocks 2 pushes the housing 13 to loosen from the lower support plate 1 and at the same time drives the two push-pull plates 4 to slide in the reverse direction away from the housing 13 through the linkage member, so that the two push-pull plates 4 are separated from the left and right side plates of the housing 13. Since the side plates of the housing 13 are not squeezed by the push-pull plates 4 and are loosened from the lower support plate 1, the housing 13 can be easily removed.

[0056] As can be seen, in the present invention, by setting the pier block 2 to be movable, the two side abutting blocks 3 and the two pier blocks 2 achieve one-to-one lapping during the upward movement of the upper die base 11. Driven by the driving mechanism, relying on the pulling force of the driving mechanism, the two pier blocks 2 are pulled upward. The pulling force of the driving mechanism is sufficient to overcome the extrusion force received by the housing 13, so that during the upward movement, the two pier blocks 2 push the housing 13 upward to loosen the housing 13 from the lower support plate 1, and at the same time drive the two push-pull plates 4 to slide in the reverse direction away from the housing 13 through the linkage member, so that the two push-pull plates 4 are separated from the left and right side plates of the housing 13. In this way, the side plates of the housing 13 are not squeezed by the push-pull plates 4 and are loosened from the lower support plate 1 at the same time, killing two birds with one stone. It can be seen that the present invention can be limited by the side abutting blocks during the pier thickening of the housing side plates to obtain stable pier thickening, and can also not be clamped by the side abutting blocks and the lower support plate after the pier thickening of the housing side plates, and can loosen the housing side plates from the lower support plate, overcoming this contradictory problem, thus facilitating the removal of the housing and effectively solving the deficiencies in the prior art.

[0057] Moreover, the side plates of the housing 13 are not squeezed by the push-pull plates 4, and the loosening between the side plates of the side abutting blocks 3 and the lower support plate 1 is automatically achieved during the upward movement of the upper die base 11, greatly improving the working speed.

[0058] In this embodiment, a limit block 203 is fixedly provided on the pier block 2, and an inner groove 305 corresponding to the limit block 203 is formed on the side abutting block 3. The limit block 203 is inserted into the corresponding inner groove 305, and the lapping of the side abutting block 3 and the pier block 2 is realized by the abutting of the bottom of the limit block 203 and the bottom of the inner groove 305.

[0059] Among them, a set of tension springs 8 are fixedly installed between the two push-pull plates 4 and the inner wall of the lower die base 12. There are multiple tension springs 8 in each set of tension springs 8. Based on the elastic force of the tension springs 8, a gap is formed between the bottom of the pier block 2 and the bottom of the inner cavity of the lower die base 12 in the initial state. When thickening the pier, during the process of driving the upper die base 11 to move downward by the driving mechanism, when the upper die base 11 presses down the housing 13 and pushes the two pier blocks 2 to move downward to the limit state, the two pier blocks 2 are in one-to-one contact with the two side abutting blocks 3 of the linkage member to limit the left and right side plates of the housing 13. Specifically, since the push-pull plate 4 is linked with the pier block 2 through the linkage member, the arrangement of the linkage member enables the push-pull plate 4 to stop at a specific position under the action of the elastic force of the tension spring 8. After the position of the push-pull plate 4 is determined, the height of the pier block 2 is specific through the linkage member. Thus, the bottom height of the pier block 2 is certain in the initial state. At this time, a gap is formed between the bottom of the pier block 2 and the bottom of the inner cavity of the lower die base 12. Due to the existence of the gap, when the upper die base 11 moves downward, it can squeeze the housing 13 to drive the two pier blocks 2 to move downward. During the process of the pier block 2 moving downward, the push-pull plate 4 is driven by the linkage member to elastically slide towards the housing 13. When the bottom of the pier block 2 moves downward to the limit state, the bottom of the pier block 2 abuts against the bottom of the inner cavity of the lower die base 12, and at the same time, the side abutting block 3 abuts against the pier block 2. At this time, the two side abutting blocks 3 realize the one-to-one limit of the left and right side plates of the housing 13. It can be seen that the present invention ingeniously utilizes the movable arrangement of the two pier blocks 2 and the gap between the bottom of the pier block 2 and the bottom of the inner cavity of the lower die base 12, so that the two side abutting blocks 3 can limit the left and right side plates of the housing 13 during the downward movement of the two pier blocks 2, which can further improve the operation speed.

[0060] Further, when thickening the pier, the left and right side plates of the housing 13 need to be bent first. After the bending is completed, the lengths of the left and right side plates of the housing 13 are different. Since the height difference between the top of the pier block 2 and the top of the lower support plate 1 is certain, when the left and right side plates of the housing 13 are longer, when the housing 13 is placed on the lower support plate 1 and abuts against the tops of the two pier blocks 2, there will be a space between the bottom surface of the top plate of the housing 13 and the top surface of the lower support plate 1 and they cannot fit. At this time, the top plate of the housing 13 is suspended (as Figure 6As shown in the figure, directly thickening the side plates of the housing 13 will cause the part of the side plates of the housing 13 between the top plate of the housing 13 and the top of the lower support plate 1 to bulge inward or even break. Therefore, in the present invention, when the housing 13 is placed on the lower support plate 1 and the bottoms of the left and right side plates of the housing 13 are in one-to-one contact with the tops of the two pier blocks 2 and there is a space between the bottom surface of the top plate of the housing 13 and the top surface of the lower support plate 1, based on the gap between the bottom of the pier block 2 and the bottom of the inner cavity of the lower die base 12, when the upper die base 11 moves downward, it first presses down the housing 13 so that the housing 13 and the two pier blocks 2 move downward synchronously. When the housing 13 moves downward, the lower support plate 1 remains stationary, so that the bottom surface of the top plate of the housing 13 gradually fits with the top surface of the lower support plate 1. Before the pier block 2 moves to the limit position, the bottom surface of the top plate of the housing 13 fits with the top surface of the lower support plate 1. When the pier block 2 moves to the limit position, the side plates of the housing 13 will be thickened. At this time, the top plate of the housing 13 is not suspended, so the above-mentioned situation where thickening the side plates of the housing 13 will cause the part of the side plates of the housing 13 between the top plate of the housing 13 and the top of the lower support plate 1 to bulge inward or even break will not occur. That is: during the process of the two pier blocks 2 being pressed downward by the upper die base 11 and moving, the bottom surface of the top plate of the housing 13 fits with the top surface of the lower support plate 1 so that when the left and right side plates of the housing 13 are thickened, the top plate of the housing 13 is not suspended.

[0061] It can be seen from this that in the present invention, since the pier block 2 is in a movable state and the gap between the pier block 2 and the lower die base 12 is utilized, during the process of the pier block 2 being pressed and moved by the housing 13, not only can the push-pull plate 4 be driven to elastically slide towards the housing 13 through the linkage member, so that the side abutting blocks 3 abut against the pier block 2 to realize the one-to-one limitation of the left and right side plates of the housing 13 by the two side abutting blocks 3; but also the gap between the pier block 2 and the lower die base 12 can be utilized to make the top plate of the housing 13 fit with the top surface of the lower support plate 1 before the side plates of the housing 13 are thickened when the top plate of the housing 13 is suspended when the housing 13 is placed, so that the top plate of the housing 13 is not suspended. Therefore, when pressing, the situation where the part of the side plates of the housing 13 between the top plate of the housing 13 and the top of the lower support plate 1 bulges inward or even breaks will not occur, and an unexpected technical effect is produced.

[0062] If the problem of the top plate of the housing 13 being suspended when the side plates of the housing 13 are thickened is solved by increasing the height difference between the top of the lower support plate 1 and the top of the pier block 2, the downward movement distance of the lower support plate 1 will be increased, thereby increasing the compression degree of the compression spring 9, and further increasing the resistance of the upper die base 11 to move downward. Therefore, it is not recommended to solve the above technical problem by increasing the height difference between the top of the lower support plate 1 and the top of the pier block 2.

[0063] In this embodiment, the connecting part includes a swing plate 7, and the two ends of the swing plate 7 are respectively provided with a lower abutment rod 702 and an upper abutment rod 703. The swing plate 7 is also provided with a rotating shaft 701 located between the lower abutment rod 702 and the upper abutment rod 703 and rotatably connected to the lower mold base 12. The pier block 2 is provided with a horizontal sliding hole 202 for the lower abutment rod 702 to slide and insert, and the push-pull plate 4 is provided with an inner sliding groove 402 for the upper abutment rod 703 to slide and insert. When the pier block 2 moves, the swing plate 7 is driven to rotate by the lower abutment rod 702, and the swing plate 7 then drives the push-pull plate 4 to slide through the upper abutment rod 703. Specifically, the horizontal length of the horizontal sliding hole 202 is greater than the diameter of the lower abutting rod 702, and the vertical length of the horizontal sliding hole 202 is equal to the diameter of the lower abutting rod 702, so that the lower abutting rod 702 can move horizontally in the horizontal sliding hole 202, the vertical length of the inner sliding groove 402 is greater than the diameter of the upper abutting rod 703, and the horizontal length of the inner sliding groove 402 is equal to the diameter of the lower abutting rod 702, so that the upper abutting rod 703 can move vertically in the inner sliding groove 402, so when the pier block 2 moves up and down, the swing plate 7 can be driven to rotate around the rotating shaft 701 through the lower abutting rod 702, and when the swing plate 7 rotates, the push-pull plate 4 is driven to slide elastically in the horizontal direction through the upper abutting rod 703, and when the push-pull plate 4 slides horizontally, it drives the side abutment block 3 to slide synchronously. The side of the push-pull plate 4 is also provided with an avoidance opening 403 corresponding to the inner sliding groove 402, and the inner sliding groove 402 is located in the avoidance opening 403, and the avoidance opening 403 is used to avoid the swing plate 7.

[0064] Among them, two support plates 14 corresponding to the two push-pull plates 4 are fixed in the lower mold base 12, and two rotating shafts 701 are rotatably set on the two support plates 14 in a one-to-one manner. The top of the support plate 14 is slidably abutted with the bottom of the push-pull plate 4, so that the support plate 14 generates a supporting force on the push-pull plate 4. A locking rod 6 slidably plugged with the push-pull plate 4 is fixedly installed on the side stop block 3 through the fixing plate 5. A through hole 405 adapted to the locking rod 6 is provided on 4 for the sliding insertion of the locking rod 6. A locking hole (not shown in the figure) for the locking rod 6 to be inserted is provided on the support plate 14. When the side stop block 3 is abutted with the pier block 2, the locking rod 6 is coaxial with the locking hole. As the locking rod 6 continues to move downward, the locking rod 6 is inserted into the corresponding locking hole to lock the side stop block 3. Specifically, during the downward movement of the upper mold base 11, after the side support block 3 abuts against the pier block 2, the locking rod 6 can be driven to be inserted into the corresponding locking hole to lock the side support block 3. When the side panels of the shell 13 are thickened, the two side support blocks 3 can limit the left and right side panels of the shell 13 more stably, and the locking of the side support blocks 3 is automatically achieved during the downward movement of the upper mold base 11, eliminating the operation of individually locking the side support blocks 3, which can effectively improve the efficiency of thickening the shell.

[0065] Similarly, when the driving mechanism drives the upper die base 11 to move upward, during the process that the upper die base 11 drives the two side abutting blocks 3 to move upward, the two side abutting blocks 3 drive the corresponding locking rods 6 to slide upward so that the locking rods 6 are disengaged from the locking holes, thereby realizing the unlocking of the side abutting blocks 3 and the push-pull plate 4.

[0066] In this embodiment, two guide rails 302 arranged front and rear are fixedly provided on the side surface of the side abutting block 3, and two T-shaped sliding plates 404 slidably inserted corresponding to the two guide rails 302 are fixedly provided on the side surface of the push-pull plate 4. The sliding insertion between the guide rails 302 and the T-shaped sliding plates 404 enables the side abutting block 3 and the push-pull plate 4 to slide relative to each other in the vertical direction and enables the side abutting block 3 and the push-pull plate 4 to slide synchronously in the horizontal direction.

[0067] Wherein, two accommodating grooves corresponding to the two guide rails 302 and penetrating through the bottom of the side abutting block 3 are formed in the side abutting block 3. Oil-absorbing cotton (not shown in the figure) is filled in the accommodating grooves, and the oil-absorbing cotton adsorbs oil liquid for reducing the friction between the guide rails 302 and the T-shaped sliding plates 404. A plug block 304 is inserted into the bottom of the accommodating groove, and the plug block 304 is used for plugging the bottom of the accommodating groove. The accommodating groove is communicated with the guide rail 302 through a penetration hole 303 formed in the side abutting block 3.

[0068] Further, a return spring (not shown in the figure) is embedded in the oil-absorbing cotton, and the plug block 304 is slidably extruded in the accommodating groove. The return spring pushes the plug block 304 to slide and reset. A ejector rod 10 corresponding to the plug block 304 is fixedly arranged in the lower die base 12. During the process that the side abutting block 3 moves downward, the ejector rod 10 extrudes the corresponding plug block 304 to compress the oil-absorbing cotton so that the oil liquid is smeared between the T-shaped sliding plate 404 and the guide rail 302 through the penetration hole 303. When the side abutting block 3 moves upward, the elastic force of the return spring is released to push the plug block 304 to reset. It can be seen that in the process that the upper die base 11 moves downward in the present invention, the function of smearing the oil liquid between the T-shaped sliding plate 404 and the guide rail 302 to reduce the sliding friction between the T-shaped sliding plate 404 and the guide rail 302 is realized, and the operation of separately smearing the oil liquid is omitted.

[0069] Second Embodiment:

[0070] As Figures 1-9 shown, a processing method for thickening the side wall of a notebook computer housing includes the following steps:

[0071] S1: Feeding: Place the housing 13 on the lower support plate 1 so that the left and right side plates of the side abutting block 3 are respectively and correspondingly abutted against the tops of the two pier blocks 2;

[0072] S2: Limit the side plates of the housing 13: The driving mechanism drives the upper die holder 11 to move downward. During the downward movement of the upper die holder 11, it squeezes the housing 13 and drives the two pier blocks 2 to move downward to the limit state through the housing 13. During the process of the two pier blocks 2 moving downward to the limit state, the corresponding two push-pull plates 4 are elastically slid by the linkage, thereby driving the two side abutting blocks 3 to abut against the two pier blocks 2 one by one to limit the left and right side plates of the housing 13;

[0073] S3: Lock the side abutting blocks 3: When the side abutting blocks 3 abut against the pier blocks 2, the lock rods 6 fixedly connected to the side abutting blocks 3 are coaxial with the lock holes on the support plate 14. As the lock rods 6 continue to move downward, the lock rods 6 are inserted into the corresponding lock holes to lock the side abutting blocks 3;

[0074] S4: Pier thickness: During the process of the lock rods 6 being inserted into the corresponding lock holes, the upper die holder 11 continuously presses down the housing 13, the side abutting blocks 3 and the lower support plate 1, and in cooperation with the two pier blocks 2, the left and right side plates of the housing 13 are thickened by piercing;

[0075] S5: Take the material: After the left and right side plates of the housing 13 are thickened by piercing, they are firmly squeezed between the side abutting blocks 3 and the lower support plate 1. During the process of driving the upper die holder 11 to move upward by the driving mechanism, the two side abutting blocks 3 are pulled upward to make the two side abutting blocks 3 overlap with the two pier blocks 2 one by one to drive the two pier blocks 2 to move upward. The upward movement of the two pier blocks 2 loosens the housing 13 and the lower support plate 1, and at the same time drives the two push-pull plates 4 to slide through the linkage to separate from the side plates of the housing 13, and finally the housing 13 can be taken off;

[0076] In step S1, when the bottoms of the left and right side plates of the housing 13 abut against the tops of the two pier blocks 2 one by one and there is a space between the bottom surface of the top plate of the housing 13 and the top surface of the lower support plate 1, in step S2, based on the two pier blocks 2 being pressed and moved downward by the upper die holder 11, during the downward movement of the pier blocks 2, the bottom surface of the top plate of the housing 13 fits against the top surface of the lower support plate 1 so that the top plate of the housing 13 does not hang in the air when the left and right side plates of the housing 13 are thickened by piercing.

[0077] In step S4, two receiving grooves corresponding to the two guide rails 302 one by one and penetrating through the bottom of the side abutting block 3 are formed in the side abutting block 3. Absorbent cotton (not shown in the figure) is filled in the receiving grooves, and the absorbent cotton adsorbs oil liquid for reducing the frictional force between the guide rail 302 and the T-shaped sliding plate 404. A plug block 304 is inserted into the bottom of the receiving groove, and the plug block 304 is used to block the bottom of the receiving groove. The receiving groove is communicated with the guide rail 302 through a penetration hole 303 formed in the side abutting block 3. A return spring (not shown in the figure) is embedded in the absorbent cotton. The plug block 304 slides and presses in the receiving groove, and the return spring pushes the plug block 304 to slide and reset. A ejector rod 10 corresponding to the plug block 304 is fixedly arranged in the lower die base 12. During the downward movement of the side abutting block 3, the ejector rod 10 presses the corresponding plug block 304 to compress the absorbent cotton so that the oil liquid is applied between the T-shaped sliding plate 404 and the guide rail 302 through the penetration hole 303. When the side abutting block 3 moves upward, the elastic force of the return spring is released to push the plug block 304 to reset. Thus, it can be seen that during the downward movement of the upper die base 11 in the present invention, the function of applying the oil liquid between the T-shaped sliding plate 404 and the guide rail 302 to reduce the sliding frictional force between the T-shaped sliding plate 404 and the guide rail 302 is realized, and the operation of separately applying the oil liquid is omitted.

[0078] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
