Description

Technical Field

[0001] This utility model relates to the field of profile forming technology, specifically to a profile side forming mold structure. Background Technology

[0002] New electronic products place increasingly higher demands on the performance of stamped profiles. The required sheet metal parts are not only small in structure but also complex in shape, resulting in more complex mold structures, numerous processes, and increased manufacturing costs. Complex stamped profiles require multiple processes for bending and forming. In existing technologies, profiles are formed by stamping. Since the forming direction of the profile is perpendicular to the up-and-down reciprocating motion of the blank holder, and when forming "L"-shaped profiles into "U"-shaped profiles, the angle-swinging method (placing the profile at multiple angles and cooperating with the top-down press to achieve bending) is generally used for forming, this leads to cumbersome steps and slow production efficiency.

[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a profile side forming mold structure, which aims to solve the problem of cumbersome processing steps and low production efficiency caused by the need to adjust the angle of the profile multiple times in the existing profile side forming process.

[0008] Furthermore, the drive inserter has a chamfer on the side near the upper die punch.

[0009] Furthermore, the upper die punch has a chamfer on the side near the upper die driving device, and a forming groove on the side away from the upper die driving device, the forming groove cooperating with the lower die punch.

[0010] Furthermore, the reset component includes: A guide rail fixing block is disposed inside the stripping plate; the stripping plate has a first through hole inside, and the guide rail fixing block is located at the top of the first through hole; A punch stop is disposed inside the guide rail fixing block; the upper die punch has a movable groove inside, and the punch stop is located in the movable groove; A reset spring is provided at one end on one side of the punch stop and at the other end on the inner wall of the moving groove, so that the upper die punch is located at the end away from the profile.

[0011] Furthermore, the bottom of the guide rail fixing block is provided with a guide groove, and the top of the upper die punch is provided with a guide rail, the guide rail and the guide groove being slidably engaged.

[0014] Furthermore, a forming groove is provided at the bottom of the stripper plate, and part of the lower die punch is located in the forming groove and cooperates with the upper die punch.

[0015] Compared with the prior art, the beneficial effects of this utility model are: In this invention, through the lateral sliding design of the upper die punch and the synergistic effect of the upper die drive device, the profile placement angle can be adjusted multiple times as in traditional processes, and the forming of "L"-shaped to "U"-shaped profiles can be completed directly within a single press stroke, greatly reducing the number of process steps and avoiding the trouble caused by frequent process transfers.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In view of the shortcomings of the prior art, this embodiment provides a profile side forming mold structure, which can be referred to as follows: As attached Figure 1 and attached Figure 2As shown, a profile 7 side forming die structure includes an upper die driving device 1, a stripper plate 2, an upper die punch 3, a reset assembly 4, a lower die plate 5, and a lower die punch 6. The upper die driving device 1 is mounted on the upper table of the press and is used to drive the upper die punch 3 to move. The stripper plate 2 is located at the bottom of the upper die driving device 1, and the upper die punch 3 is laterally slidably mounted at the bottom of the stripper plate 2. The upper die punch 3 cooperates with the upper die driving device 1, and the upper die driving device 1 is used to drive the upper die punch 3 to move towards the profile 7. Extrusion molding is performed; the reset component 4 is located inside the stripper plate 2 and cooperates with the upper die punch 3. When the upper die punch 3 is not working, it is located at the end away from the profile 7 under the action of the reset component 4; the lower die plate 5 is set on the lower table of the press, and the lower die punch 6 is set on the lower die plate 5 to correspond to the bending part of the profile 7. The lower die punch 6 cooperates with the upper die punch 3 to make the profile 7 bend and form. The lower die punch 6 forms a "U" shaped groove at the bending part of the profile 7 to meet the bending requirements.

[0031] The upper die drive device 1 is mounted on the upper platform of the press, and its output end is rigidly connected to the stripper plate 2. It can be driven by the press to achieve reciprocating motion in the vertical direction. It also has a built-in transverse drive module for precise control of the horizontal displacement of the upper die punch 3. The stripper plate 2 is located at the bottom of the upper die drive device 1 and has a transverse slide inside. The slide has a "T" shaped cross section, which provides guidance and support for the upper die punch 3 and restricts its movement trajectory to avoid deviation during the forming process. The upper die punch 3 is slidably mounted on the bottom of the stripper plate 2. Its forming end adopts an arc transition design. The upper die punch 3 cooperates with the transverse drive module of the upper die drive device 1 and can move along the slide towards the profile 7 under the driving action to realize the extrusion forming of the profile 7.

[0032] The reset assembly 4 is located inside the stripper plate 2 and consists of a high-strength reset spring 43 and a guide fixing block. The two ends of the reset spring 43 are fixedly connected to the inner wall of the guide fixing block and the upper die punch 3, respectively. The guide fixing block passes through the upper die punch 3 and is rigidly connected to the stripper plate 2. When the upper die punch 3 is not working, it remains in its initial position away from the profile 7 under the elastic force of the reset assembly 4. When the upper die punch 3 is working, the upper die drive device 1 can compress the high-strength reset spring 43. The lower die punch 6 is located on the lower template 5, and its top has a forming surface that matches the profile 7. The lower die punch 6 is located in a groove. The forming surfaces of the lower die punch 6 and the upper die punch 3 are complementary. Their precise cooperation allows the profile 7 to be bent at a preset angle.

[0033] Specifically, during the bending operation of profile 7, the press drives the upper die drive device 1 downward. The stripper plate 2 first contacts the lower template 5 and is located on one side of profile 7. Then, the lateral drive module of the upper die drive device 1 is activated, pushing the upper die punch 3 along the slide of the stripper plate 2 towards profile 7, cooperating with the lower die punch 6 to extrude and bend profile 7. At this time, the arc transition forming surface of the upper die punch 3 and the forming surface of the lower die punch 6 work together to ensure that the bending point of profile 7 is evenly stressed, avoiding wrinkles or cracks. After forming is completed, the lateral drive module of the upper die drive device 1 resets, and the upper die punch 3 returns to its initial position along the slide under the spring force of the reset component 4. At the same time, the press drives the upper die drive device 1 upward, and the stripper plate 2 separates from the lower template 5, completing one forming cycle.

[0034] Compared to existing technologies, the traditional "angle-swing forming" method requires multiple adjustments to the profile 7's posture, necessitating repositioning after each bend. This not only involves cumbersome procedures but also increases the risk of positioning errors affecting forming accuracy. This solution, through the lateral sliding design of the upper die punch 3 and the coordinated action of the upper and lower dies, allows bending forming to be completed in a single stroke, eliminating the need for multiple angle adjustments. Simultaneously, the reset component 4 ensures that the upper die punch 3 automatically returns to its initial position after each forming process, eliminating the need for manual intervention. This improves production efficiency and ensures consistent forming across batches.

[0035] Through the above technical solution, this application achieves efficient forming of complex profiles 7, solving the problem of limited forming direction in traditional processes through the coordinated action of lateral driving and vertical clamping; it also ensures the stability of forming quality, effectively controlling bending dimensional tolerances with the precise guidance of stripper plate 2 and reliable reset component 4; at the same time, it simplifies the operation process, completing the forming operation without frequent adjustment of profile 7 angle, greatly reducing manual labor intensity, and is particularly suitable for the mass production of small-sized complex sheet metal parts in new electronic products.

[0036] As attached Figure 9 and attached Figure 10 As shown, profile 7 is arranged in an "L" shape before it is formed, and in a "U" shape after it is formed.

[0037] In this embodiment, as shown in the appendix Figure 2 Appendix Figure 4 and attached Figure 5 As shown, the upper die driving device 1 includes an upper die base 11, a driving cutter 12, and a telescopic guide assembly 13. The upper die base 11 is set on the upper table of the press, and the driving cutter 12 is set on the bottom wall of the upper die base 11. The driving cutter 12 passes through the stripper plate 2 and cooperates with the upper die punch 3. One end of the telescopic guide assembly 13 is set inside the upper die base 11, and the other end is set inside the stripper plate 2, so that the stripper plate 2 can be in a spaced-out state with the upper die base 11 when not in operation.

[0038] The drive cutter 12 has a wedge-shaped structure, and its bottom inclined surface forms a sliding fit with the wedge-shaped groove on the top of the upper die punch 3. When the press drives the upper die base 11 downward, the drive cutter 12 converts the vertical pressure into lateral thrust through the inclined surface contact, precisely driving the upper die punch 3 to move along the slide of the stripper plate 2. One end of the telescopic guide assembly 13 is fixed in the countersunk hole inside the upper die base 11, and the other end is set in the stripper plate 2, so that the stripper plate 2 and the upper die base 11 maintain a gap distance of 10-15mm when not in operation, which not only avoids ineffective contact wear between components, but also reserves a buffer stroke for the pressure transmission when the upper die base 11 moves downward.

[0039] When the equipment is started, the press drives the upper mold base 11 to move downward, and the stripper plate 2 contacts the lower mold base. The bottom of the stripper plate 2 has a first through hole 21 and covers the profile 7. The upper mold punch 3 is located at some part of the profile 7. As the upper mold base 11 continues to move downward, the wedge-shaped surface of the drive cutter 12 is in complete contact with the upper mold punch 3. The vertical pressure is converted into a lateral driving force through the inclined surface, pushing the upper mold punch 3 to complete the bending action. After the forming is completed, the press drives the upper mold base 11 to move upward. The upper mold base 11 first disengages from the stripper plate 2. As the upper mold base 11 moves upward and the telescopic guide component 13 is in an extended state, after the telescopic guide component 13 is fully extended, the drive cutter 12 disengages from the upper mold punch 3. The upper mold punch 3 retracts under the action of the reset component 4. Then, under the action of the telescopic guide component 13, the stripper plate 2 is moved upward to achieve demolding.

[0040] This structure cleverly transforms the vertical motion of the press into the lateral force required for molding through the force conversion principle of mechanical transmission, eliminating the need for an additional power source. At the same time, the telescopic guide component 13 ensures the orderly linkage between the stripper plate 2 and the upper mold base 11, which not only guarantees molding accuracy but also simplifies the design of the drive system, further improving the reliability and economy of the mold.

[0041] In this embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the telescopic guide assembly 13 includes a telescopic cylinder 131, a piston 132, and a piston rod 133. The telescopic cylinder 131 is disposed inside the upper mold base 11, and a first spring 134 is disposed on the inner top wall of the telescopic cylinder 131. The piston 132 is slidably disposed inside the telescopic cylinder 131, and the top wall of the piston 132 is connected to the first spring 134. Under the action of the first spring 134, the piston 132 is located at the bottom of the telescopic cylinder 131. A piston rod 133 is disposed on the bottom wall of the piston 132. A sliding hole is disposed at the bottom of the telescopic cylinder 131, and the piston rod 133 is slidably disposed in the sliding hole and protrudes outward. The bottom of the piston rod 133 is connected to the stripper plate 2.

[0042] The top of the telescopic cylinder 131 is rigidly connected to the upper mold base 11 by bolts. A self-lubricating bearing is embedded in the sliding hole at the bottom, ensuring smooth sliding of the piston rod 133 and preventing dust from entering the cylinder. The first spring 134 is a high-strength compression spring, with its two ends fixedly connected to the inner top wall of the telescopic cylinder 131 and the top wall of the piston 132, respectively. In its natural state, the spring force keeps the piston 132 tightly against the inner bottom wall of the telescopic cylinder 131, ensuring a stable gap between the stripper plate 2 and the upper mold base 11 in the non-working state. The piston 132 may have a through hole inside, which does not serve a sealing function. The piston rod 133 is a solid tempered steel rod, with its top threadedly connected to the piston 132 and equipped with an anti-loosening nut, and its bottom rigidly connected to the stripper plate 2.

[0043] When the press drives the upper die holder 11 downward, the piston rod 133, under the reaction force of the stripper plate 2, pushes the piston 132 upward. The first spring 134 is compressed and stores energy. At this time, the through hole of the piston 132 can quickly balance the air pressure inside and outside the telescopic cylinder 131, avoiding the impact of air compression resistance on the motion accuracy. After the stripper plate 2 contacts the profile 7, the piston 132 continues to move upward. The through hole structure allows the airflow in the upper and lower chambers of the piston 132 to flow freely, eliminating the interference of air pressure damping on pressure transmission and ensuring that the vertical force of the upper die holder 11 can stably act on the stripper plate 2, achieving reliable pressing of the profile 7. After molding is completed, the first spring 134 pushes the piston 132 to reset. The through hole also accelerates the airflow return, allowing the stripper plate 2 to quickly detach from the lower die plate 5, reducing the ineffective stroke time.

[0044] In this embodiment, as shown in the appendix Figure 5 As shown, the drive cutter 12 has a chamfer on the side near the upper die punch 3, and the upper die punch 3 has a chamfer on the side near the upper die drive device 1.

[0045] This chamfer structure is not a simple edge trimming, but plays a key guiding and buffering role in the force transmission process: when the drive cutter 12 moves down with the upper mold base 11 and contacts the upper mold punch 3, the inclined surface of the chamfer can first form a gradual fit with the contact end of the upper mold punch 3, avoiding the rigid impact generated when the traditional right-angle edge contacts, and effectively protecting the contact surface of the two from wear or cracking.

[0046] Meanwhile, the guiding characteristics of the chamfer ensure precise alignment between the drive cutter 12 and the wedge groove of the upper die punch 3. Even with minor assembly errors or movement misalignments, the chamfered surface can achieve complete contact between the two through sliding self-adjustment, ensuring a stable conversion of vertical pressure into lateral thrust. Furthermore, the smooth chamfered surface reduces frictional resistance during relative movement, lowers energy loss, and makes the lateral movement of the upper die punch 3 smoother, further improving the response speed and precision of the molding action.

[0047] In this embodiment, as shown in the appendix Figure 7As shown, a forming groove 31 is provided on the side of the upper die punch 3 away from the upper die driving device 1. The forming groove 31 cooperates with the lower die punch 6 to realize the bending and forming of the profile 7.

[0048] Among them, as attached Figure 8 As shown, one side of the lower die punch 6 is an abutment block, and part of the abutment block is located in the forming groove 31 so that the profile 7 can be bent into a "U" shape when the upper die punch 3 approaches the lower die punch 6.

[0049] In this embodiment, as shown in the appendix Figure 5 As shown, the reset assembly 4 includes a guide rail 33 fixing block, a punch stop block 42, and a reset spring 43. The stripper plate 2 has a first through hole 21 inside. The guide rail 33 fixing block is located at the top of the first through hole 21, and the bottom of the first through hole 21 is used to accommodate the upper die punch 3. The punch stop block 42 is located inside the guide rail 33 fixing block, and the upper die punch 3 has a moving groove 32 inside. The punch stop block 42 extends into the moving groove 32. One end of the reset spring 43 is located on the punch stop block 42, and the other end is located on the inner wall of the moving groove 32, so that the upper die punch 3 is located at the end away from the profile 7.

[0050] When the mold is in the forming operation, the drive cutter 12 of the upper mold drive device 1 pushes the upper mold punch 3 to move towards the profile 7. At this time, the inner wall of the moving groove 32 of the upper mold punch 3 compresses the return spring 43, and the punch stop 42 slides synchronously along the moving groove 32 and maintains guidance. After the forming is completed, the drive cutter 12 is withdrawn, and the return spring 43 rebounds quickly under the action of elastic potential energy, pushing the upper mold punch 3 to move in the opposite direction along the first through hole 21 until the punch stop 42 contacts the end of the moving groove 32. The upper mold punch 3 accurately returns to the initial position, ready for the next forming.

[0051] By cooperating with the guide rail 33 fixing block and the punch stop block 42, the lateral guidance of the upper die punch 3 is realized, and its longitudinal displacement is restricted to avoid skewing during the forming process. The overall structure has no complex transmission parts and relies on mechanical elasticity to achieve automatic reset. It not only has a fast response speed, but also reduces the risk of failure and is suitable for high-frequency batch production scenarios.

[0052] In this embodiment, as shown in the appendix Figure 6 As shown, the bottom of the guide rail 33 fixing block is provided with a guide groove 44, and the top of the upper die punch 3 is provided with a guide rail 33. The guide rail 33 and the guide groove 44 slide together to realize the sliding of the upper die punch 3.

[0053] Furthermore, the length of the first through hole 21 is greater than the length of the upper die punch 3.

[0054] The length direction is the moving direction of the upper die punch 3, and the length of the first through hole 21 is greater than the length of the upper die punch 3, thereby ensuring the movement of the upper die punch 3 and the placement space of the profile 7.

[0055] In this embodiment, a slot is provided on the top of the guide rail 33 fixing block, and the drive insert 12 is slidably disposed in the slot to facilitate the drive insert 12 to cooperate with the upper die punch 3.

[0056] In this embodiment, a forming groove is provided at the bottom of the stripper plate 2. The forming groove is connected to the first through hole 21, and part of the lower die punch 6 is located in the forming groove.

[0057] The forming groove is a reserved space for bending the profile 7, and it is also used to place the lower die punch 6 to cooperate with the upper die punch 3 to achieve the side forming of the profile 7.
