Description

Technical Field

[0001] This invention belongs to the field of automotive mold technology, and specifically relates to an automotive sheet metal mold processing device. Background Technology

[0002] In the field of stamping processing of automotive molds, the forming of sheet metal usually requires multiple processes such as pressing and cutting to meet the production needs of different products.

[0003] However, in actual production and processing, when the same batch of plates only differ in external dimensions while other structures are identical, traditional processes often require two independent molds to complete the cutting and forming and simple pressing operations respectively. This not only increases the number of molds and occupies production space, but also causes processing interruptions due to frequent mold changes, significantly reducing production efficiency and increasing equipment investment and maintenance costs. Alternatively, the cutting function can be turned on and off by mechanical disassembly or manual adjustment, which is cumbersome and makes it difficult to guarantee the positional accuracy after switching. Moreover, each mold change takes a long time, which seriously restricts the production line cycle time and cannot meet the production needs of modern production lines for rapid switching of multiple types of plates.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes an automotive sheet metal mold processing device, comprising: an upper body and a lower body. The lower end face of the upper body is connected to a pressure part and a cutting part. The upper end face of the lower body is provided with a drive assembly, a baffle, a cutting guide part, and a pressure-bearing part located directly below the pressure part. The cutting part and the upper body, and the cutting guide part and the lower body are all slidably connected in a second direction. The baffle and the lower body are slidably connected in a first direction, and the second direction forms a predetermined angle with the first direction.

[0006] The upper end face of the cutting guide and the lower end face of the cutting guide are respectively provided with a first guide block and a second guide block that are adapted to each other. The first guide block and the second guide block form a sloping sliding dock, and the sloping surface of the first guide block faces the second direction and the cutting guide. The output end of the drive component is connected to a baffle. The baffle and the side wall of the cutting guide are respectively connected to a first stop block and a second stop block that are adapted to each other. The ends of the first stop block and the second stop block form a sloping sliding dock, and the sloping surface of the first stop block faces the first direction and the cutting guide.

[0007] Furthermore, it also includes a first elastic member extending along the second direction, with the two ends of the first elastic member connected to the cutting guide and the upper seat respectively, so that the first stop and the second stop remain in a compressed state.

[0008] Furthermore, it also includes a second elastic member extending along the second direction, with its two ends connected to the cutting part and the upper seat, so that the cutting part and the pressure part maintain a predetermined distance.

[0009] Furthermore, the cross-sections of both the first and second blocks adopt a right-angled trapezoidal structure, and the sidewalls of both the first and second blocks adopt a curved surface transition.

[0010] Furthermore, it also includes a first straight block and a second straight block. The first straight block is disposed on the side wall of the baffle and is arranged at a distance from the first block on the same side. The second straight block is disposed on the side wall of the cutting guide and is arranged at a distance from the second block on the same side.

[0011] When the distance between the cutting guide and the baffle is at its minimum, the first straight block and the second straight block abut against each other.

[0012] Furthermore, the upper end face of the lower seat is provided with a support stop and a support top seat, the side wall of the support stop and the side wall of the baffle are slidably fitted together, and the support stop is located on the side of the baffle that faces away from the cutting guide.

[0013] The support top and the baffle are arranged coaxially. One end of the baffle is connected to the output end of the drive component, and the other end of the baffle maintains a predetermined distance from the support top.

[0014] Furthermore, it also includes protrusions and cover plates. The sidewalls of the baffle facing and away from the cutting guide are provided with several protrusions. Several cover plates are provided on the upper end face of the lower seat body in a one-to-one correspondence with several protrusions, and the several cover plates and the upper end face of the protrusions are slidably fitted together.

[0015] Furthermore, the first guide block includes several first flat plates and several outer conical plate blocks, and the second guide block includes several second flat plates and several inner conical plate blocks. The several first flat plates are respectively connected to the several second flat plates to form a docking, and the several outer conical plate blocks are respectively connected to the several inner conical plate blocks to form a docking.

[0016] Furthermore, the baffle sidewall array is provided with weight reduction grooves, and the weight reduction grooves and the first guide block are arranged in a front-to-back position in the second direction.

[0017] Furthermore, the drive assembly uses a telescopic cylinder.

[0018] Compared with the prior art, the embodiments of the present invention have at least the following advantages:

[0019] 1. The automotive sheet metal mold processing device of the present invention proposes a sliding connection between the cutting part and the upper seat, and between the cutting guide part and the lower seat in a second direction. The position of the baffle is changed in the first direction by the drive assembly. Based on the inclined sliding docking of the ends of the first and second blocks, the position of the cutting guide part is changed synchronously. Based on the inclined sliding docking of the first and second guide blocks, the position of the cutting guide part on the cutting part in the second direction is changed and limited during the pressing down of the upper seat. The output end of the cutting part is guided to cut the sheet metal to complete the pressure cutting operation. The baffle is reset to achieve the spaced arrangement of the cutting guide part and the cutting part, which meets the requirements of single pressure operation of sheet metal. The device of this application can meet the dual-mode switching of pressure cutting operation and single pressure operation, and meet the diverse production needs of sheet metal.

[0020] 2. At the same time, based on the sliding connection between the baffle and the lower seat in the first direction, compared with the conventional drive component that drives along the second direction through the output end, the usable area of ​​the upper surface of the lower seat is reduced. On the basis of the baffle and the lower seat being connected as a whole, the resistance of the baffle to the reaction force is greatly improved, so as to adapt to the driving force when the upper seat presses down the plate, ensuring the stable operation of plate pressing and cutting, and improving the overall service life and stability of the device.

Detailed Implementation

[0030] The following description provides many different embodiments or examples for implementing various features of the invention. The elements and arrangements described in the specific examples below are only for concise expression of the invention and are merely examples, not intended to limit the invention.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides an automotive sheet metal mold processing device. Figure 1 A schematic diagram of an automotive sheet metal mold processing device according to an embodiment of the present invention is shown. (Refer to...) Figures 1 to 4 The automotive sheet metal mold processing device includes: an upper seat 1 and a lower seat 2;

[0033] The lower end face of the upper seat 1 is connected to the pressurizing part 3 and the cutting part 4. The upper end face of the lower seat 2 is provided with a driving assembly 5, a baffle 6, a cutting guide part 7, and a pressure bearing part 8 located directly below the pressurizing part 3. The cutting part 4 and the upper seat 1, and the cutting guide part 7 and the lower seat 2 are all slidably connected in the second direction. The baffle 6 and the lower seat 2 are slidably connected in the first direction. The second direction and the first direction form a predetermined angle. For example, the angle between the second direction and the first direction is 90°.

[0034] The upper end face of the cutting guide 7 and the lower end face of the cutting part 4 are respectively provided with a first guide block 9 and a second guide block 10 that are adapted to each other. The first guide block 9 and the second guide block 10 form a sloping sliding dock, and the sloping surface of the first guide block 9 faces the second direction and the cutting part 4.

[0035] The output end of the drive assembly 5 is connected to the baffle 6. The sidewalls of the baffle 6 and the cutting guide 7 are respectively connected to the first stop 11 and the second stop 12. The ends of the first stop 11 and the second stop 12 form a sloping sliding dock, and the sloping surface of the first stop 11 faces the first direction and the cutting guide 7.

[0036] exist Figure 4 In the example shown, the upper end face of the cutting guide 7 is provided with five first guide blocks 9, and the five first guide blocks 9 are arranged in an array in the first direction. The lower end face of the cutting part 4 is provided with five second guide blocks 10, and the five second guide blocks 10 are arranged in an array in the first direction. The inclined surface of the first guide block 9 for docking with the second guide block 10 faces the pressure bearing part 8 and the cutting part 4.

[0037] Correspondingly, the sidewall of the baffle 6 is connected to three first blocks 11, and the three first blocks 11 are arranged in an array in the first direction. The sidewall of the cutting guide 7 is connected to three second blocks 12, and the three second blocks 12 are arranged in an array in the first direction. The inclined surface of the first block 11 that is used to dock with the second block 12 faces the drive assembly 5 and the cutting guide 7.

[0038] In actual use, the automotive sheet metal mold proposed in this invention moves the cutting guide 7 until the distance between the baffle 6 and the driving component 5 is at its maximum, while keeping the adjacent sidewalls of the first stop 11 and the second stop 12 in contact. The driving component 5 drives the baffle 6 to change position in the first direction, so that as the distance between the baffle 6 and the driving component 5 gradually decreases, the driving force of the baffle 6 in the first direction is converted into the driving force of the cutting guide 7 in the second direction based on the inclined contact of the first stop 11 and the second stop 12, thus driving the distance between the cutting guide 7 and the baffle 6 to increase synchronously until the cutting guide 7 moves along the second direction to directly below the cutting part 4.

[0039] At this time, the upper seat 1 is driven by external equipment to press vertically downward, so that the pressure part 3 and the pressure bearing part 8 pressurize the upper and lower side walls of the sheet material, and press the sheet material into the mold shape corresponding to the upper end face of the pressure bearing part 8 and the lower end face of the pressure part 3; at the same time, the cutting part 4 and the cutting guide part 7 are brought into contact, and under the guidance of the first guide block 9 and the second guide block 10 with inclined sliding dock, the cutting part 4 is moved in position in the second direction and moves closer to the cutting part 4 until the output end of the cutting part 4 docks with the cutting line of the sheet material, and the upper seat 1 is pressed to complete the cutting operation of the cutting part 4 on the sheet material.

[0040] When only pressure needs to be applied to the sheet metal without cutting, the drive assembly 5 maximizes the distance between the baffle 6 and the drive assembly 5, and moves the cutting guide 7 until the distance between the cutting guide 7 and the baffle 6 is minimized. At this time, the cutting part 4 and the cutting guide 7 are vertically misaligned. When the external equipment drives the upper body 1 to press vertically downward, the pressure part 3 and the pressure bearing part 8 apply pressure to the upper and lower side walls of the sheet metal, pressing the sheet metal into a mold shape corresponding to the upper end face of the pressure bearing part 8 and the lower end face of the pressure part 3. However, due to the misaligned arrangement of the cutting part 4 and the cutting guide 7, the second guide block 10 of the cutting part 4 and the first guide block 9 of the cutting guide 7 are spaced apart. The cutting part 4 and the upper body 1 continue to maintain a sliding connection, avoiding a hard connection between the output end of the cutting part 4 and the sheet metal, thereby avoiding cutting of the sheet metal by the output end of the cutting part 4.

[0041] It should be further explained that during the cutting process of the sheet metal by the pressing cutting section 4, when the baffle 6 drives the cutting guide section 7 directly below the cutting section 4, the pressing driving force of the cutting section 4, guided by the first guide block 9 and the second guide block 10, will generate a reverse force in the second direction on the cutting guide section 7, which is directed towards the baffle 6. This application achieves the cancellation of the reverse force through the baffle 6. Based on the sliding connection between the baffle 6 and the lower seat 2 in the first direction, compared to the conventional driving component along the second direction via the output end, this reduces the usable area of ​​the upper surface of the lower seat 2. Furthermore, by connecting the baffle 6 and the lower seat 2 as a single piece, it greatly improves the baffle 6's ability to withstand the reverse force, adapting to the driving force when the upper seat 1 presses down on the sheet metal, ensuring stable sheet metal pressing and cutting operations, and improving the overall service life and stability of the device.

[0042] exist Figure 5 and Figure 6The example shown also includes a first elastic member 13 and a second elastic member 14 extending along the second direction. The first elastic member 13 is connected at both ends to the cutting guide 7 and the upper seat 1, respectively. The first elastic member 13 is located on the side of the cutting guide 7 facing the pressure bearing part 8, so that the first stop 11 and the second stop 12 are kept in a pressing state, ensuring that when the distance between the baffle 6 and the drive assembly 5 is at its maximum, the distance between the cutting guide 7 and the baffle 6 is at its minimum, providing the cutting guide 7 with a driving force to move towards the baffle 6 along the second direction.

[0043] The second elastic member 14 is connected to the cutting part 4 and the upper seat 1 at both ends, respectively, and provides the cutting part 4 with a force in the second direction away from the pressure part 3. When the plate cutting operation is completed and the upper seat 1 moves upward, the cutting part 4 is driven to move in the second direction away from the pressure part 3 until the cutting part 4 and the pressure part 3 maintain a predetermined distance.

[0044] Meanwhile, when the cutting part 4 and the cutting guide part 7 are arranged in a staggered manner in the vertical direction, the second elastic member 14 keeps the cutting part 4 and the pressing part 3 at a predetermined distance, directly avoiding contact between the cutting part 4 and the sheet during the pressing process, and further improving the smoothness and stability of the device when performing sheet pressing operation alone.

[0045] In this case, there are also a first straight block 18 and a second straight block 19. The first straight block 18 is disposed on the side wall of the baffle 6 and is arranged at a distance from the first block 11 on the same side. The second straight block 19 is disposed on the side wall of the cutting guide 7 and is arranged at a distance from the second block 12 on the same side.

[0046] In this embodiment, the cross-sections of the first block 11 and the second block 12 are both right-angled trapezoidal structures, and the sidewalls of the first block 11 and the second block 12 are both curved transitions. The sidewalls of the first block 11 and the second block 12 each include a straight sidewall, an upper top sidewall, a lower top sidewall, and a sloping sidewall.

[0047] When the distance between the cutting guide 7 and the baffle 6 is at its minimum, the first straight block 18 and the second straight block 19 abut together, and the inclined sidewalls of the first block 11 and the second block 12 abut together; when the distance between the cutting guide 7 and the baffle 6 is at its maximum, the cutting guide 7 and the cutting part 4 are arranged vertically, and the upper top sidewalls of the first block 11 and the second block 12 abut together.

[0048] Based on the abutment of the first straight block 18 and the second straight block 19, as well as the abutment of the upper top sidewalls of the first block 11 and the second block 12, the contact area of ​​the first block 11 and the second block 12 pressing against each other during cutting and non-cutting operations is increased, thereby improving the stability of the transmission connection between the baffle 6 and the cutting guide 7.

[0049] refer to Figure 2 To further improve the stability of the baffle 6, the upper surface of the lower seat 2 is provided with a support seat 15 and a support top seat 16. The side wall of the support seat 15 is slidably fitted with the side wall of the baffle 6, and the support seat 15 is located on the side of the baffle 6 facing away from the cutting guide part 7. In the second direction, the position of the baffle 6 is limited, thereby increasing the upper limit of the driving force used by the device to press down the plate material, so as to meet the operation requirements of pressing the plate material.

[0050] Meanwhile, the support top seat 16 and the baffle 6 are arranged coaxially. One end of the baffle 6 is connected to the output end of the drive component 5, and the other end of the baffle 6 maintains a predetermined distance from the support top seat 16. This limits the position of the baffle 6 in the first direction, preventing the drive component 5 from driving the baffle 6 to move too far in the first direction, thereby limiting the movement range of the baffle 6 and the movement range of the cutting guide 7.

[0051] In this case, it also includes protrusions 20 and cover plates 21. The sidewalls of the baffle 6 facing and away from the cutting guide 7 are provided with a plurality of protrusions 20. The plurality of protrusions 20 are arranged in an array in the first direction, and the protrusions 20 on both sides are staggered. A plurality of cover plates 21 are provided on the upper end surface of the lower seat 2 in a one-to-one correspondence with the plurality of protrusions 20, and the plurality of cover plates 21 and the upper end surface of the protrusions 20 form a sliding fit, thereby realizing the position limitation of the baffle 6 in the vertical direction, so as to improve the stability of the baffle 6 on the upper end surface of the lower seat 2.

[0052] refer to Figure 3 The sidewall array of the baffle 6 is provided with weight-reducing grooves 17, which are arranged in a front-to-back position with the first guide block 9 in the second direction. When the weight of a localized area of ​​the baffle 6 increases due to the first stop block 11, the weight-reducing grooves 17 reduce the weight at the corresponding location, thereby maintaining the overall weight balance and stability of the baffle 6.

[0053] It should be noted that this application does not limit the number of the first block 11, the second block 12, and the weight reduction groove 17, but the number of the first block 11, the second block 12, and the weight reduction groove 17 needs to be kept uniform in order to meet the technical requirements of weight reduction and weight balance.

[0054] Correspondingly, the drive component 5 adopts a telescopic cylinder, and the output end of the telescopic cylinder is coaxially connected to the baffle 6.
