Description

Technical Field

[0001] This invention relates to the field of tooling technology for processing deformable products, and more specifically to a tooling and processing method for processing deformable products. Background Technology

[0002] Currently, for products that are bent and deformed due to stamping or other cutting methods, the external grinding process is difficult, with a large amount of grinding required. It requires more grinding to meet the accuracy requirements, and the complex shape and strict tolerances further increase the machining allowance. The performance of the equipment (such as the rigidity of the grinding machine and the characteristics of the grinding wheel) and the process parameters (such as the cutting speed and feed rate) also directly affect the processing efficiency and grinding amount. In order to reduce grinding time and belt wear, and improve the processing efficiency and quality of deformed workpieces, we need to address these issues. Summary of the Invention

[0003] In view of this, a tooling and processing method for processing deformed products that can achieve uniform processing, high efficiency, and high yield is provided.

[0004] A tooling for processing deformable products includes a processing table, a fixture, a horizontal pusher, a limiting member, and a clamping assembly. The horizontal pusher is mounted on the processing table. The clamping assembly includes a driving member and a pressing member. The fixture is mounted on the processing table. The pressing member is located above the fixture and can press the edge of the workpiece to be processed under the drive of the driving member to deform the edge. The limiting member is configured to limit the edge of the workpiece to be processed and keep the edge in a deformed state. The limiting member has multiple limiting grooves and positioning pins. Multiple workpieces in each group are placed in the multiple limiting grooves of the limiting member, and after deformation, the positioning pins press and limit the deformed edge of the workpiece. The horizontal pusher is used to push the workpiece horizontally to move the part of the workpiece to be processed to a position where it can be processed.

[0005] Specifically, the transverse push component includes a transverse push cylinder, a transverse push plate, and a shaft. The transverse push cylinder is mounted on the processing table via a mounting plate. The transverse push plate is connected to the shaft, which is the output rod of the transverse push cylinder. The transverse push plate is used to push the same end of multiple workpieces to make the multiple workpieces move synchronously.

[0006] Furthermore, the horizontal push plate is provided with mounting holes, and the shaft is installed on the horizontal push plate and connected to the horizontal push plate by fasteners passing through the mounting holes. The horizontal push plate is pushed laterally by the shaft of the horizontal push cylinder, and the deformed workpiece is moved by the horizontal push plate.

[0007] Specifically, the fixture includes a clamping platform and two clamping plates. The clamping platform is mounted on the processing table and has a supporting surface perpendicular to the horizontal push plate. The two clamping plates are placed parallel to each other along the length of the workpiece on the clamping platform. Each clamping plate is provided with multiple fixed protrusions spaced parallel to each other. Every two adjacent fixed protrusions block the sides of a group of workpieces arranged side by side. Multiple workpieces are divided into multiple groups, and each group has multiple rows of workpieces arranged side by side between two fixed protrusions and supported on the bottom surface of the clamping plate.

[0008] Furthermore, the clamping plate is provided with multiple clamping grooves, and multiple fixing protrusions are respectively installed in the clamping grooves. Multiple workpieces are placed in the clamping grooves, and then the deformed workpieces are clamped in the clamping plate by the fixing protrusions.

[0009] Furthermore, the limiting component includes a limiting plate and the positioning pin. The limiting plate is mounted on the clamping platform and has multiple limiting grooves. The limiting grooves are used to place the deformed workpiece and prevent the deformed workpiece from moving left or right. The positioning pin is mounted on the limiting plate across multiple limiting grooves and prevents the deformed product from moving up or down.

[0010] Furthermore, the limiting plate includes a base plate and a plurality of parallel support strips protruding upward from the base plate. The base plate and the plurality of support strips are an integral structure, for example, an integrally formed structure. The plurality of support strips are aligned with or parallel to the arrangement direction of the plurality of workpieces. The top of the plurality of support strips is provided with through holes, and the positioning pin passes through the through holes at the top of all support strips to press the upper edge of each workpiece. Every two support strips and the base plate define a limiting groove. The plurality of workpieces are arranged in a group and sandwiched between two adjacent support strips. Each group of workpieces is limited in a corresponding limiting groove. There is a predetermined height distance between the positioning pin and the base plate to keep the workpiece in a compressed and deformed state. The predetermined height distance is slightly less than the longitudinal length of the workpiece. The positioning pin is a single pin that passes through all the through holes. The positioning pin spans and elastically presses against the upper edge of the plurality of workpieces, so that the upper edge of the workpiece continues to maintain the deformed state after being pressed down by the pressing assembly.

[0011] Specifically, the driving component includes two symmetrically arranged downward pressure cylinders, which are respectively mounted on the bottom of the processing table by bolts.

[0012] Furthermore, the pressing component includes two pressing push rods and a pressing push plate. The pressing push plate includes a connecting plate and a pressing plate. The connecting plate is used to connect the pressing push rods. The processing table is provided with two through holes. One end of the two pressing push rods is installed on the pressing cylinder, and the other end of the two pressing push rods respectively passes through the through holes and connects to the pressing push plate, thereby installing the pressing component on the processing table. The pressing plate is installed on the connecting plate and vertically set on the fixture for pressing the deformed product. The pressing cylinder pushes the pressing push rods, thereby driving the pressing push plate to press down. And, a method for processing deformable products, applicable to the tooling for processing deformable products as described above, the method comprising the following steps: Multiple workpieces to be processed are placed on a fixture, and the multiple workpieces are placed side by side into at least one group. The limiting member has multiple limiting grooves and positioning pins. In each group, multiple workpieces are placed in the multiple limiting grooves of the limiting member. The pressing component drives the lower pressing component, which presses down on the edge of the workpiece to be processed, causing the edge to deform. Multiple workpieces in a deformed state are simultaneously ground. Each workpiece mounted on the fixture is divided into a left part, a middle part, and a right part. The left and right parts are located on both sides of the positioning pin, and the middle part is located below the positioning pin. The left or right part is ground first. After the left or right part is ground, the workpieces are moved by the horizontal pusher, so that the middle part of each workpiece is away from the position blocked by the positioning pin. Then, the exposed middle part and another part of the left and right parts are ground to complete the grinding of all workpieces.

[0013] The aforementioned tooling for processing deformed products utilizes the workpiece's own elasticity, which deforms under pressure. A clamping assembly pre-deforms the workpiece's edge to be processed, and a limiting component maintains this deformed state. This facilitates processing of the deformed edge, avoiding the unevenness often seen in traditional direct edge processing, or the unevenness of the processed surface caused by localized pressure deformation. This results in a more uniform, integrated grinding surface, reducing the amount of deformation required for grinding and improving processing efficiency. It solves the current problems of large processing volumes and excessive grinding when processing deformed workpieces, reducing grinding time and belt wear, and improving processing efficiency.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0021] Please see Figures 1-5 This illustration shows a tooling for processing deformable products according to an embodiment of the present invention, including a processing table 10, a horizontal pusher 20, a clamp 30, a limiting member 40, and a pressing assembly 50. The horizontal pusher 20 is mounted on the processing table 10. The pressing assembly 50 includes a driving member 51 and a pressing member 52. The clamp 30 is mounted on the processing table 10. The pressing member 52 is located above the clamp 30 and can press the edge of the workpiece 60 to be processed under the drive of the driving member 51 to deform the edge. The limiting member 40 is configured to limit the edge of the workpiece 60 to be processed and keep the edge in a deformed state. The horizontal pusher 20 is used to push the workpiece 60 horizontally to move the part of the workpiece 60 to be processed to a position where it can be processed. The limiting member 40 has a plurality of limiting grooves 43 and positioning pins 42. In each group, a plurality of workpieces 60 are placed in the plurality of limiting grooves 43 of the limiting member 40 and, after deformation, the edges of the workpiece 60 are pressed and limited by the positioning pins 42.

[0022] In some preferred embodiments, the processing table 10 is provided with a mounting plate 11, and the transverse pusher 20 includes a transverse pusher cylinder 21, a transverse pusher plate 22, and a shaft 23. The transverse pusher cylinder 21 is mounted on the processing table 10 via the mounting plate 11. The transverse pusher plate 22 is connected to the shaft 23, and the shaft 23 is the output rod of the transverse pusher cylinder 21. The transverse pusher plate 22 is used to push the same end of multiple workpieces 60 so that the multiple workpieces 60 are moved synchronously.

[0023] Specifically, the horizontal push plate 22 is provided with mounting holes 221, and the shaft 23 is installed on the horizontal push plate 22 and connected to the horizontal push plate 22 by fasteners passing through the mounting holes 221. The horizontal push plate 22 is pushed laterally by the shaft 23 of the horizontal push cylinder 21, and the deformed workpiece 60 is moved by the horizontal push plate 22.

[0024] Preferably, the fixture 30 includes a clamping platform 31 and two clamping plates 32. The clamping platform 31 is mounted on the processing table 10 and has a supporting surface perpendicular to the transverse push plate 22. The two limiting members 40 are placed parallel to each other along the length of the workpiece 60 on the clamping platform 31. Each clamping plate 32 has a plurality of fixed protrusions 33 spaced parallel to each other, and every two adjacent fixed protrusions 33 block both sides of a group of workpieces 60 arranged side by side. The multiple workpieces 60 are divided into multiple groups, and each group has multiple rows arranged side by side between two fixed protrusions 33 and supported on the bottom surface of the clamping plate 32.

[0025] Preferably, the clamping plate 32 is provided with a plurality of clamping grooves 34, and a plurality of fixing protrusions 33 are respectively installed in the clamping grooves 34. A plurality of workpieces 60 are placed in the clamping grooves 34, and then the deformed workpieces 60 are clamped in the clamping plate 32 by the fixing protrusions 33.

[0026] In some specific embodiments, the limiting member 40 includes a limiting plate 41 and a positioning pin 42. The limiting plate 41 is mounted on the clamping platform 31. The limiting plate 41 is provided with a limiting groove 43 corresponding to the clamping groove 34. The limiting groove 43 is used to place the deformed workpiece 60 to prevent the deformed workpiece 60 from moving left and right.

[0027] Specifically, the positioning pin 42 is mounted on the limiting plate 41 across multiple limiting grooves 43, preventing the deformed product from moving up and down. More specifically, the limiting plate 41 includes a base plate 411 and multiple parallel support bars 412 protruding upward from the base plate 411. The base plate 411 and the multiple support bars 412 are an integral structure, for example, a one-piece molded structure. The multiple support bars 412 are aligned with or parallel to the arrangement direction of the multiple workpieces 60. The top of the multiple support bars 412 is provided with a through hole 413, and the positioning pin 42 passes through the through hole 413 at the top of all the support bars 412 to press down the upper edge of each workpiece 60. Every two support bars 412 and the base plate 411 define one of the limiting grooves 43. The multiple workpieces 60 are arranged in a group and sandwiched between two adjacent support bars 412, and each group of workpieces 60 is confined in a corresponding limiting groove 43. The positioning pin 42 and the base plate 411 have a predetermined height distance so that the workpiece 60 is kept in a compressed and deformed state. For example, the predetermined height distance is slightly less than the longitudinal length of the workpiece 60. The positioning pin 42 is a single pin that passes through all the through holes 413, that is, it spans across and elastically presses against the upper edge of multiple sets of workpieces 60, so that the upper edge of the workpiece 60 continues to maintain the deformed state after being pressed down by the pressing assembly 50.

[0028] Specifically, the driving component 51 includes two symmetrically arranged downward pressing cylinders 51, which are respectively mounted on the bottom of the processing table 10 by bolts.

[0029] Preferably, the processing table 10 is provided with two through holes 12, and the pressing component 52 includes two pressing push rods 521 and a pressing push plate 522. One end of the two pressing push rods 521 is installed on the pressing cylinder 51, and the other end of the two pressing push rods 521 respectively passes through the through holes 12 and connects to the pressing push plate 522, thereby installing the pressing component 52 on the processing table 10.

[0030] Further, the pressing push plate 522 includes a connecting plate 5221 and a pressing plate 5222. The connecting plate 5221 is used to connect the pressing push rod 521. The pressing plate 5222 is mounted on the connecting plate 5221 and vertically arranged on the fixture 30 for pressing the deformed product. The pressing cylinder 51 pushes the pressing push rod 521, thereby driving the pressing push plate 522 to press down. After pressing down, the upper edge of the workpiece 60 is deformed. At this time, the pressing plate 5222 is kept temporarily stationary. The positioning pin 42 is inserted into the through hole 413 at the top of the support bar 412, and the positioning pin 42 is kept in a state of pressing the upper edge of the workpiece 60 tightly. Then the pressing device can be removed, and the workpiece 60 can be ground by belt abrasion. As shown in the figure, after the entire left side of each workpiece 60 in the indicated position is finished by belt grinding, the horizontal pusher 22 is driven by the horizontal pusher cylinder 21. The horizontal pusher 22 pushes each workpiece 60 to the right. Since each workpiece 60 is pressed by the positioning pin 42, and the positioning pin 42 has a certain elasticity, the horizontal pusher 22 allows the workpiece 60 to move to the right. However, the positioning pin 42 remains in a pressing state during the movement to prevent the workpiece 60 from deforming and returning to its original position. When the workpiece 60 is in position, for example, when the parts covered by the pressing component 50 and the positioning pin 42 are exposed, that is, when these covered parts of the workpiece 60 are exposed to the range of action of the belt, the grinding operation on the right side is performed. In this way, the parts that are inconvenient to be processed on the left side due to being covered by the pressing component 50 and the positioning pin 42 can be fully taken care of when processing on the right side, thereby realizing the complete processing of the entire workpiece 60.

[0031] The tooling of this invention utilizes the inherent elasticity of the workpiece 60, which deforms under pressure. The clamping assembly 50 pre-processes the deformed edges of the workpiece 60 by pressing down on the push plate 522. This avoids the uneven edges often found in traditional methods of directly machining the workpiece 60's edges, or the unevenness of the machined surface caused by localized deformation under pressure during processing. This results in a more uniform and integrated grinding surface, reducing the amount of deformation to be ground and improving the processing efficiency of the deformed workpiece 60. It solves the problems of large processing volume and excessive grinding volume, reducing grinding time and belt wear when processing deformed workpieces 60. By using the tooling of this application, the workpiece 60 can receive the necessary processing, ensuring all processing areas are properly addressed, resulting in more uniform processing effects. It avoids rework or repeated processing, improving processing efficiency and yield. Practical experience has proven that the products processed using this tooling are significantly superior to those processed using traditional methods.
