Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a round cake punching positioning tool. Background Art

[0002] In the current bimetallic brake drum production field, round punching is a key cutting process that has an important impact on material utilization and production efficiency. Round punching is to punch out round steel plates according to the specified size and quantity from steel plates that have been pre-cut to size and shape.

[0003] The traditional round cake punching process relies on manual positioning, and the operator needs to rely on visual judgment to determine the center position of the round cake to be punched. Figure 1 As shown. This process not only requires operators to have rich experience and high concentration, but also introduces significant positioning errors due to human subjective factors, which directly lead to inconsistent spacing between the round cakes and low utilization of the steel plate. Specifically, the inaccuracy of manual positioning often makes the control of the edge margin around each round cake unstable. On the one hand, it may lead to a reduction in the number of final round cakes, increase waste generation, and push up manufacturing costs; on the other hand, the operator's continuous high-intensity visual and physical labor is prone to fatigue, which further restricts the improvement of production efficiency.

[0004] Therefore, how to provide a round cake positioning tool to replace traditional manual positioning, reduce material waste, improve production efficiency, and reduce the labor intensity of operators is a technical problem that technical personnel in this field currently need to solve.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] See also Figure 2 , Figure 3 and Figure 5 The present application provides a round cake positioning tool, comprising a support plate and a vertical plate 1, the vertical plate 1 is symmetrically arranged on both sides of the support plate; a positioning plate 2, the positioning plate 2 is connected to the inner sides of the two vertical plates 1 through a driving mechanism, and the driving mechanism can make the positioning plate 2 reciprocate in the lateral direction; a mounting seat 3, fixedly connected to the support plate, the mounting seat 3 can move longitudinally on the support plate, and one end of the mounting seat 3 is in a suspended state; a top plate 4, the top plate 4 is connected to the support plate through a lifting mechanism 5, and the lifting mechanism 5 can make the top plate 4 reciprocate in the vertical direction; positioning pins 6, the positioning pins 6 are symmetrically arranged on the upper surface of the top plate 4 away from the lifting mechanism 5 at one end, so as to position the steel plate 7.

[0038] Specifically, the circular cake positioning tool of the present application includes a support plate and a vertical plate 1 firmly connected to the front and rear sides of the support plate. Secondly, two positioning plates 2 are correspondingly connected to the inner sides of the two vertical plates 1 through a driving mechanism, so that the positioning plate 2 can achieve reciprocating movement in the transverse direction (the transverse direction is the direction in which the two vertical plates 1 face each other), and thus the steel plate 7 can be positioned. Since the vertical plate 1 is arranged on the front and rear sides of the support plate, the vertical plate 1 includes a front vertical plate and a rear vertical plate, and the positioning plate 2 includes a front positioning plate and a rear positioning plate. In addition, it also includes a mounting seat 3, which is fixedly connected to the support plate and can move longitudinally on the support plate (the longitudinal direction is the length extension direction of the steel plate 7), so that the mounting seat 3 can adjust its position according to actual needs. It is particularly worth mentioning that the left end of the mounting seat 3 is in a suspended state, the top plate 4 is connected to the support plate through the lifting mechanism 5, and the lifting mechanism 5 is arranged at the left end of the mounting seat 3, the lifting mechanism 5 can control the reciprocating movement of the top plate 4 in the vertical direction, and the positioning pins 6 are symmetrically arranged on the upper surface of the top plate 4 away from the lifting mechanism 5 (that is, the positioning pins 6 are symmetrically arranged on the upper surface of the right end of the top plate 4), and then the positioning pins 6 follow the top plate 4 to move in the vertical direction to realize the positioning of the steel plate 7.

[0039] The working principle of the circular cake positioning tool of the present application is as follows: Since the steel plate 7 is designed to be rectangular and has a certain width, two rows of circular cakes need to be punched out thereon. First, the first row of circular cakes on the upper side is punched, so that the rear positioning plate moves in its lateral direction under the action of the driving mechanism, that is, moves in the direction away from the rear vertical plate, until the distance from the vertical projection point of the front edge of the stamping die on the steel plate 7 to the front edge of the steel plate 7 is controlled to be about 5-10mm, that is, L1 is between 5-10mm, at this time, the rear positioning plate remains stationary, and the lifting mechanism 5 is in the initial position.

[0040] Next, the operator will push the steel plate 7 forward to the left end along the rear positioning plate on the roller track. During this process, the horizontal coordinates of the steel plate 7 remain unchanged. The operator visually adjusts to ensure that the distance from the vertical projection point of the left edge of the punching die on the steel plate 7 to the left edge of the steel plate 7 is controlled to be about 5-10mm, that is, L2 is between 5-10mm. The punching die is located above the support plate (not shown in the figure). When it is working, it will punch down the first round cake, thereby forming the first through hole 71 on the steel plate 7, as shown in FIG. Figure 2 shown.

[0041] Afterwards, the operator pushes the steel plate 7 to the left until the visual positioning pin 6 is located below the first through hole 71. At this time, the lifting mechanism 5 is started to drive the top plate 4 and the positioning pin 6 to move upward until the positioning pin 6 enters the first through hole 71 and abuts against the right edge of the hole wall. The operator stops pushing the steel plate 7 and adjusts the longitudinal position of the mounting seat 3 to ensure that the distance from the vertical projection point of the left edge of the stamping die on the steel plate to the right edge of the hole wall of the first through hole 71 is 5mm, that is, L=5mm. After the adjustment is completed, the mounting seat 3 is locked, and then the stamping die punches down a second round cake to form a second through hole 72, as shown in FIG. Figure 3 shown.

[0042] Next, the lifting mechanism 5 is placed in the initial position, and the operator pushes the steel plate 7 to the left until the positioning pin 6 is visually located below the second through hole 72. At this time, the lifting mechanism 5 is started to drive the top plate 4 and the positioning pin 6 to move upward until the positioning pin 6 enters the second through hole 72 and abuts against the right edge of the hole wall. The operator stops pushing the steel plate 7, and the stamping die punches out the third round cake to form the third through hole.

[0043] This process will be repeated. After each round cake is punched, the lifting mechanism 5 will return to the initial position, and the steel plate 7 will continue to move to the left until the positioning pin 6 is aligned with the next through hole. In this way, the distance between the center distances of each through hole can be accurately controlled to ensure that the distance between the edges of the adjacent hole walls of two through holes is about 5mm. The same method is also applicable to the round cake punching at the lower end of the steel plate 7. It is only necessary to fit the steel plate 7 to the front positioning plate for positioning, thereby forming Figure 5 Steel plate shown.

[0044] In summary, the round cake positioning tool provided by the present application realizes accurate positioning and efficient punching of the steel plate 7 by combining mechanical positioning with manual visual adjustment. It not only significantly improves the accuracy and efficiency of the round cake, but also greatly reduces the labor intensity of the operator. In addition, since the distance between the edges of the walls of two adjacent through holes is controlled, that is, Figure 5The L length values ​​are all equal. Compared with the prior art, the length of the steel plate required in the present application is shorter when preparing the same number of round cakes, thereby achieving cost savings. Specifically, when preparing 7 round cakes per row of steel plates, the length of the steel plate required in the present application is 35 mm shorter than that of the prior art. This advantage will bring significant economic benefits in industrial production.

[0045] On the basis of the above embodiment, a waist-shaped hole 31 is provided on the mounting seat 3, and the mounting seat 3 and the support plate are fixedly connected by bolts passing through the waist-shaped hole 31 and cooperating with nuts.

[0046] Specifically, the waist-shaped hole 31, also known as an oblong hole or an elliptical hole, is characterized in that the length of the hole is significantly greater than the width, thereby allowing the bolt to move longitudinally within a certain range. The connection between the mounting seat 3 and the support plate of the present application is achieved by bolts passing through the waist-shaped hole 31 and then being fixed with nuts.

[0047] Specifically, when the longitudinal position of the mounting base 3 on the support plate needs to be adjusted, the bolts and nuts can be loosened to allow the mounting base 3 to move freely within the range allowed by the waist-shaped hole 31. Once adjusted to a suitable position, the bolts and nuts can be tightened again to fix the mounting base 3 at the new position. This not only facilitates installation and adjustment, but also improves applicability and flexibility.

[0048] Based on the above embodiments, Figure 4 As shown, the lifting mechanism 5 includes a guide column 51, which is symmetrically arranged on the upper surface of the mounting seat 3, and the top plate 4 is provided with a through hole corresponding to the guide column 51 so as to be sleeved on the guide column 51; an actuator 52, the fixed end of the actuator 52 is arranged on the mounting seat 3, and the output end of the actuator 52 is fixedly connected to the top plate 4, which is used to drive the top plate 4 to reciprocate in the vertical direction; a balancing block 53, the balancing block 53 is arranged on the upper surface of one end of the top plate 4 away from the positioning pin 6. Since the top plate 4 is eccentrically designed, a balancing effect is achieved through the setting of the balancing block 53.

[0049] Specifically, the guide posts 51 are symmetrically arranged on the upper surface of the mounting base 3 to provide stable guidance for the movement of the top plate 4. The top plate 4 is provided with through holes corresponding to the guide posts 51, so that the top plate 4 can be mounted on the guide posts 51 and move vertically along them. The guide posts 51 not only ensure the linearity and stability of the movement of the top plate 4, but also help prevent the top plate 4 from shifting or tilting during the movement.

[0050] The fixed end of the actuator 52 is mounted on the mounting base 3 to ensure its stability and reliability. The output end of the actuator 52 is fixedly connected to the top plate 4. When the actuator 52 is working, it can directly drive the top plate 4 to reciprocate in the vertical direction.

[0051] The balancing block 53 is arranged on the upper surface of the end of the top plate 4 away from the positioning pin 6 (i.e., the balancing block 53 is arranged on the left side of the top plate 4). Since the top plate 4 is eccentrically designed, an unbalanced moment may be generated during the lifting process. The balancing block 53 is arranged to offset this imbalance and ensure that the top plate 4 can move smoothly and accurately. The weight and position of the balancing block 53 are calculated and designed to ensure that the top plate 4 always maintains dynamic balance during the entire lifting process.

[0052] In summary, the lifting mechanism 5 realizes the movement of the top plate 4 and the positioning pin 6 in the vertical direction through the coordinated action of the guide column 51 , the actuator 52 and the balance block 53 .

[0053] Based on the above embodiment, the actuator 52 is a cylinder, which establishes a signal connection with the controller, and the controller also establishes a signal connection with a foot button or a manual button, wherein the foot button or the manual button includes an up switch and a down switch.

[0054] Specifically, the cylinder, as an actuator, establishes a signal connection with the controller, and then the controller can send instructions to the cylinder to control its telescopic action, thereby driving the top plate 4 and the positioning pin 6 to move up and down.

[0055] The controller also establishes a signal connection with a foot button or a manual button. The foot button or the manual button includes an ascending switch and a descending switch for receiving instructions from an operator.

[0056] When the operator clicks the rising switch, an rising signal is sent to the controller; similarly, when the operator clicks the falling switch, a falling signal is sent. When the controller receives the rising signal, it processes the signal and sends a command to the cylinder to extend the cylinder. The cylinder extension stroke is 50mm, thereby driving the top plate 4 and the positioning pin 6 to rise to the preset position. The preset position can be preset by the controller to ensure that the height of each rise is consistent.

[0057] On the contrary, when the controller receives the descending signal, it sends a command to the cylinder to shorten it, so that the top plate 4 and the positioning pin 6 descend to the initial position. The initial position is the position when the cylinder is fully retracted.

[0058] Based on the above embodiment, a locking screw 54 is provided on the top of the guide column 51 .

[0059] Specifically, by providing the locking screw 54, it is equivalent to ensuring that the top plate 4 is always sleeved on the guide column 51, and the length of the guide column 51 is greater than the extension stroke of the cylinder.

[0060] Based on the above embodiment, the number of guide posts 51 is not less than two groups, and the number of guide posts 51 in each group is not less than two.

[0061] Specifically, in the punching pancake positioning tool, the design of the guide posts 51 adopts a configuration of multiple groups, that is, the number of guide posts 51 is not less than two groups, and the number of guide posts 51 in each group is not less than two. The preferred number of guide posts 51 in this application is preferably 4, and all are fixedly arranged on the top plate 4. The arrangement of four guide posts 51 can significantly enhance the stability of the top plate 4 during the lifting process. When the top plate 4 moves along the multiple guide posts 51, it can move up and down more smoothly and accurately, ensuring that the top plate 4 is stable and not skewed when rising or falling.

[0062] Based on the above embodiment, the driving mechanism includes an L-plate 8 and a screw 9. The L-plate 8 is symmetrically arranged on the left and right sides of the vertical plate 1. The vertical plate 1 is provided with a through hole for the screw 9 to pass through. The tail end of the screw 9 is connected to the positioning plate 2. The screw 9 is provided with a first locking nut and a second locking nut corresponding to the two sides of the L-plate 8, and a handle is provided at the head end of the screw 9.

[0063] That is to say, the L-plate 8 is located on the left and right sides of the vertical plate 1 and is symmetrically arranged. The main function of the L-plate 8 is to serve as a support and guide for the screw 9 to ensure the stability and accuracy of the screw 9 during the adjustment process. The screw 9 passes through the through hole set on the vertical plate 1, and then the screw 9 can move back and forth under the guidance of the L-plate 8. The tail end of the screw 9 is connected to the positioning plate 2. Therefore, by moving the screw 9, the position of the positioning plate 2 can be accurately adjusted. On the screw 9, a first locking nut and a second locking nut are correspondingly provided on both sides of the L-plate 8. These two locking nuts are used to fix the position of the screw 9 to prevent it from moving during the stamping process. When the position of the positioning plate 2 needs to be adjusted, the locking nut can be loosened, the screw 9 can be moved to the desired position, and then the locking nut can be tightened to fix it.

[0064] A handle is provided at the head end of the screw rod 9 , so that the operator can move the screw rod 9 more conveniently and labor-savingly, thereby improving the efficiency and convenience of adjusting the position of the positioning plate 2 .

[0065] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The above examples are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
