Description

Technical Field

[0001] This utility model belongs to the technical field of special production equipment for automotive suspension systems, and in particular relates to a quenching and forming machine for automotive leaf springs and guide arms with automatic tooth adjustment. Background Technology

[0002] Currently, multi-rake tooth forming machines in China all rely on manual tooth adjustment. The method involves placing a standard mold on the support base, loosening the fastening screws of the upper and lower rake teeth, and adjusting the height of each tooth one by one against the mold. After adjustment, all screws must be tightened. Once production begins, test pieces are produced. If a tooth is misshapen or has defects such as indentations, the corresponding tooth needs to be located, and the screws loosened for fine-tuning. Sometimes multiple fine-tuning adjustments are required. The entire tooth adjustment process is tedious, time-consuming, and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a quenching and forming machine for automotive leaf springs and guide arms with automatic tooth adjustment, so as to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An automatic tooth-adjustable quenching and forming machine for automotive leaf springs and guide arms includes a frame. The frame is connected to an upper tooth seat via a forming guide rail and a forming cylinder. The upper tooth seat holds a plurality of upper rake teeth via a locking mechanism. Friction blocks are spaced apart between the upper rake teeth. A lower tooth seat is fixed at the lower part of the frame. The lower tooth seat holds a plurality of lower rake teeth via a locking mechanism. Friction blocks are spaced apart between the lower rake teeth. A lower support seat is fixed on the lower tooth seat. A clamping cylinder is installed on the frame. A clamping plate is fixed at the output end of the clamping cylinder. A tooth-adjusting mechanism is installed on one side of the frame. The tooth-adjusting mechanism contains a plurality of tooth-adjusting cylinders.

[0006] Furthermore, the frame has a square frame structure, with two forming guide rails and two forming cylinders. The two forming guide rails are symmetrically fixed on both sides inside the square frame structure of the frame. The two ends of the upper gear seat are slidably connected to the two forming guide rails respectively. The forming cylinders are fixed at the top of the frame, and the output ends of the two forming cylinders pass through the frame and are hinged to the two ends of the upper gear seat.

[0007] Furthermore, both the upper and lower gear seats are square frame structures with open top and bottom. The clamping plate and the lower support seat are located in the center of the upper and lower gear seats, respectively. The clamping plate passes through the upper gear seat, and the clamping plate and the lower support seat are positioned opposite each other.

[0008] Furthermore, the locking mechanism includes a housing, which is fixed to the upper and lower gear seats. Locking cylinders are fixed at both ends of the housing. A locking wedge is fixed at the output end of the locking cylinder after passing through the housing. A wedge is threaded through the locking wedge. The wedge passes through the housing and extends into the interior of the square frame structure of the upper and lower gear seats. The upper gear seat clamps several upper rake teeth with the inner wall of the upper gear seat through the wedge, and the lower gear seat clamps several upper rake teeth with the inner wall of the lower gear seat through the wedge.

[0009] Furthermore, the locking wedge has an inclined opening, one side of which passes through the wedge block. One end of the wedge block inside the box abuts against the inner wall of the other side of the locking wedge opening, and the end of the wedge block protruding from the box has an inclined surface.

[0010] Furthermore, the number of upper and lower rake teeth is the same, and the positions of the upper and lower rake teeth correspond one-to-one. The working ends of the upper and lower rake teeth are both T-shaped, and a stop plate is fixed to the top of the upper rake tooth, with one end of the stop plate protruding out of the upper rake tooth.

[0011] Furthermore, the upper and lower rake teeth are symmetrically arranged on both sides of the clamping plate and the lower support seat. There are friction blocks between the upper rake teeth and the upper tooth seat, and between the lower rake teeth and the lower tooth seat. There are friction inclined blocks between the upper and lower rake teeth and the wedge block. One side of the friction inclined block has an inclined surface that matches the wedge block, and the side of the friction inclined block with the inclined surface is in contact with the wedge block.

[0012] Furthermore, the tooth-adjusting mechanism includes lifting guide rails, screws, and a housing. There are two lifting guide rails and two screws.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0027] like Figure 1-7As shown, an automatic tooth-adjustable quenching and forming machine for automotive leaf springs and guide arms includes a frame 1. The frame 1 is connected to an upper tooth seat 4 via a forming guide rail 2 and a forming cylinder 3. The upper tooth seat 4 holds a plurality of upper rake teeth 5 by a locking mechanism 12. Friction blocks 6 are spaced apart between the upper rake teeth 5. A lower tooth seat 7 is fixed at the lower part of the frame 1. The lower tooth seat 7 holds a plurality of lower rake teeth 8 by a locking mechanism 12. Friction blocks 6 are spaced apart between the lower rake teeth 8. A lower support seat 9 is fixed on the lower tooth seat 7. A clamping cylinder 10 is installed on the frame 1. A clamping plate 11 is fixed at the output end of the clamping cylinder 10. A tooth-adjusting mechanism 19 is installed on one side of the frame 1. The tooth-adjusting mechanism 19 is provided with a plurality of tooth-adjusting cylinders 24.

[0028] The frame 1 has a square frame structure, with two forming guide rails 2 and two forming cylinders 3. The two forming guide rails 2 are symmetrically fixed on both sides inside the square frame structure of the frame 1. The two ends of the upper tooth seat 4 are slidably connected to the two forming guide rails 2 respectively. The forming cylinders 3 are fixed to the top of the frame 1, and the output ends of the two forming cylinders 3 pass through the frame 1 and are hinged to the two ends of the upper tooth seat 4. The frame 1 is not completely closed; the bottom of the frame 1 is open to facilitate the accommodation of the bottom end of the lower rake teeth 8. The two forming cylinders 3 operate synchronously, driving the upper tooth seat 4 to move downward, thereby performing the forming operation on the sheet material.

[0029] Both the upper gear seat 4 and the lower gear seat 7 are square frame structures with open top and bottom. The clamping plate 11 and the lower support seat 9 are located in the center of the upper gear seat 4 and the lower gear seat 7, respectively. The clamping plate 11 passes through the upper gear seat 4, and the clamping plate 11 and the lower support seat 9 are positioned vertically opposite each other. The clamping plate 11 and the lower support seat 9 are used to clamp the plate from the middle.

[0030] The locking mechanism 12 includes a housing 13, which is fixed to the upper gear seat 4 and the lower gear seat 7. Locking cylinders 14 are fixed at both ends of the housing 13. A locking wedge 15 is fixed to the output end of the locking cylinder 14 after passing through the housing 13. A wedge block 16 is threaded through the locking wedge 15, penetrating the housing 13 and extending into the interior of the square frame structure of the upper gear seat 4 and the lower gear seat 7. The upper gear seat 4 clamps several upper rake teeth 5 against its inner wall via the wedge block 16, and the lower gear seat 7 clamps several upper rake teeth 5 against its inner wall via the wedge block 16. The movement of the locking cylinder 14 causes the locking wedge 15 to move, and the locking wedge 15 cooperates with the wedge block 16 to achieve the movement of the wedge block 16.

[0031] The locking wedge 15 has an inclined opening, one side of which passes through the wedge block 16. One end of the wedge block 16 located inside the box 13 abuts against the inner wall of the other side of the opening of the locking wedge 15. The end of the wedge block 16 protruding from the box 13 has an inclined surface.

[0032] The number of upper rake teeth 5 and lower rake teeth 8 is the same, and the positions of upper rake teeth 5 and lower rake teeth 8 correspond one-to-one. The working ends of upper rake teeth 5 and lower rake teeth 8 are both T-shaped. A stop plate 17 is fixed to the top of upper rake teeth 5, and one end of the stop plate 17 protrudes out of upper rake teeth 5.

[0033] The upper rake teeth 5 and lower rake teeth 8 are symmetrically arranged on both sides of the clamping plate 11 and the lower support seat 9, respectively. Friction blocks 6 are placed between the upper rake teeth 5 and the upper tooth seat 4, and between the lower rake teeth 8 and the lower tooth seat 7. Friction inclined blocks 18 are placed between the upper rake teeth 5, the lower rake teeth 8 and the wedge block 16. One side of the friction inclined block 18 has an inclined surface that matches the wedge block 16, and the inclined side of the friction inclined block 18 is in contact with the wedge block 16. The cooperation between the friction inclined block 18 and the wedge block 16 enables the wedge block 16 to compress or release the upper rake teeth 5 / lower rake teeth 8. When the wedge block 16 is compressed, it is in a locked state, and vice versa.

[0034] The tooth-adjusting mechanism 19 includes lifting guide rails 20, screws 21, and a housing 22. There are two lifting guide rails 20 and two screws 21. The two lifting guide rails 20 are symmetrically fixed at both ends of one side of the frame 1. The two screws 21 are rotatably connected to both ends of one side of the frame 1. Both ends of the housing 22 are slidably connected to the lifting guide rails 20, and both ends of the housing 22 are threaded with two screws 21. A synchronous motor 23 is connected to the top of each screw 21 and is fixed to the frame 1. Tooth-adjusting cylinders 24 are linearly arranged and fixed inside the housing 22. The output ends of the tooth-adjusting cylinders 24 penetrate the housing 22. The number of tooth-adjusting cylinders 24 is the same as the number of upper rake teeth 5, and their positions correspond one-to-one with the upper rake teeth 5. The extension or retraction of the output ends of the tooth-adjusting cylinders 24 can push and avoid the upper rake teeth 5 / lower rake teeth 8, thereby adjusting the positions of the upper rake teeth 5 / lower rake teeth 8 as needed.

[0035] The working principle of this utility model is as follows:

[0036] The synchronous motor 23, the tooth adjusting cylinder 24, and the locking cylinder are electrically connected to the control system of the quenching and forming machine. The control system of the quenching and forming machine is existing technology and can input the shape data of the workpiece to obtain the position information of all the upper rake teeth 5 and lower rake teeth 8.

[0037] Before the tooth-adjusting mechanism 19 begins adjusting the upper rake teeth 5 and lower rake teeth 8, the control system first activates the locking cylinder 14 of the locking mechanism 12, causing the output end of the locking cylinder 14 to extend, thereby pushing the locking wedge 15 to move. Because the locking wedge 15 has an inclined opening, this causes the position of the wedge block 16 to change, such as... Figure 5 The locking wedge 15 on the left side moves to the right, and the wedge block 16 slides from the highest position of the opening to the lowest position, resulting in a downward displacement (here, up, down, left, and right are limited to...). Figure 5In this process, the upper rake tooth 5 and friction block 6, which were originally locked by the upper tooth seat 4 and the wedge block 16, are released. However, there is still friction between the upper tooth seat 4 and the friction block 6, so the upper tooth seat 4 will not fall off, thus changing from the locked state to the released state. The lower rake tooth 8 is also switched to the released state through the corresponding locking mechanism 12.

[0038] When the tooth-adjusting mechanism 19 begins to adjust the upper rake tooth 5 and the lower rake tooth 8, the control system starts the synchronous operation of the two synchronous motors 23 (how the two synchronous motors 23 achieve synchronous operation is existing technology and will not be described in detail here), causing the screw 21 to rotate, thereby driving the housing 22 to rise along the lifting guide rail 20 to above the upper rake tooth 5. The output ends of all the tooth-adjusting cylinders 24 extend, the synchronous motors 23 drive the housing 22 to descend, and the tooth-adjusting cylinders 24 push the upper rake tooth 5 downward through the stop plate 17. When it reaches the set highest position, the upper rake tooth 5 at the highest position is in place, and the output end of the corresponding tooth-adjusting cylinder 24 retracts, thereby avoiding the stop plate 17 on the upper rake tooth 5 in place. This continues, and when an upper rake tooth 5 is in place, the corresponding tooth-adjusting cylinder 24 retracts to avoid it. After all the upper rake teeth 5 are in place, the tooth adjusting mechanism 19 continues to move downwards, avoiding the T-shaped ends of all the upper rake teeth 5. Then, all the tooth adjusting cylinders 24 extend again to position the lower rake teeth 8. The positioning process of the lower rake teeth 8 is similar to that of the upper rake teeth 5, except that the tooth adjusting cylinders 24 push the T-shaped ends (working ends) of the lower rake teeth 8 into place. After all the upper rake teeth 5 and lower rake teeth 8 are in place, the locking cylinder 14 of the locking mechanism 12 retracts, thus switching from the loosened state to the locked state.

[0039] If misalignment is found in one of the upper rake teeth 5 or the lower rake tooth 8 after the quenching and forming process, it will be individually corrected through the tooth adjustment mechanism 19. Before correction, the locking mechanism 12 will be switched to the loosened state. Figure 6 As shown, if the position of an upper rake tooth 5 is tilted upwards (becomes higher), the tooth adjusting mechanism 19 extends from above the upper rake tooth 5 through the corresponding tooth adjusting cylinder 24 and pushes the corresponding stop plate 17 downwards into place; if the position of an upper rake tooth 5 is tilted downwards (becomes lower), the tooth adjusting mechanism 19 extends from below the upper rake tooth 5 through the corresponding tooth adjusting cylinder 24 and pushes the corresponding stop plate 17 upwards into place. The method for individually correcting the lower rake tooth 8 is similar to that for the upper rake tooth 5, except that the tooth adjusting cylinder 24 corrects the lower rake tooth 8 by pushing the T-shaped end (working end) of the lower rake tooth 8 from above or below. After individual correction is completed, the locking mechanism 12 switches to the locking state. The control system can position the tooth adjusting mechanism 19 according to the position information of the upper rake tooth 5 and the lower rake tooth 8, and a displacement sensor can be installed on the frame 1 to control the lifting distance of the tooth adjusting mechanism 19.

[0040] After the upper rake teeth 5 and lower rake teeth 8 are in place, the heated sheet material is placed on the lower support seat 9 (center to center). The clamping cylinder 10 is activated and extended, and the clamping plate 11 passes through the upper tooth seat 4 to press the sheet material. The two forming cylinders 3 operate synchronously (how the two cylinders achieve synchronous operation is existing technology and will not be described in detail here), driving the upper tooth seat 4 to move downward. The upper rake teeth 5 and lower rake teeth 8 squeeze the sheet material to form it. Subsequently, the forming cylinders 3 and clamping cylinders 10 retract, and the formed sheet material is removed.

[0041] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
