Description

Technical Field

[0001] The present invention belongs to the technical field of mold processing, and particularly relates to a milling-flattening mold. Background Art

[0002] In the traditional processing technology, the process of milling and flattening pins usually requires preliminary stamping and forming of the strip on a punching press first, and then transferring the strip to a milling machine for secondary processing. Generally speaking, one-time stamping can only operate on one side of the strip. This secondary processing method requires multiple transfers and re-clamping of the strip, consuming a lot of time and resulting in low processing efficiency. Moreover, during the conversion process of the strip between different devices, positioning errors are likely to occur, ultimately leading to problems affecting the processing accuracy.

[0003] Secondly, when the existing milling-flattening molds mill and flatten the pins, they can only focus on a single milling-flattening operation. For other processing requirements of the strip, such as segmentation, cutting, punching, and cutting, additional equipment and processes are required to complete. For example, for a long strip, the existing molds cannot perform segmentation operations while milling and flattening, and additional cutting equipment is needed for assistance; when cutting the front and back sides of the strip to cooperate with later rubber rolling, separate processing equipment is also required. This single-function processing method not only increases equipment investment and floor area, but also makes the entire production process long and complex, making it difficult to achieve high-efficiency production.

[0004] Continuing, in the production line used to implement all the above preparation processes, due to the limitations of traditional molds and processing equipment, it is impossible to accurately limit the strip at each station, resulting in the position of the strip being extremely prone to deviation during the processing, ultimately affecting the processing quality and accuracy.

[0005] Therefore, the present invention designs a mold that can complete multiple operations such as milling and flattening, segmentation, cutting, punching, and cutting in one processing process, and accurately limits the strip during the processing, aiming to improve production efficiency, reduce costs, and improve the quality and accuracy of products.

However, the mold of the present invention integrates multiple functions, and all processing can be completed with only one device, greatly reducing equipment investment. The reduction in the number of devices can also correspondingly save the floor area occupied by the equipment, ultimately achieving a reduction in the production space cost.

The reduction in the number of devices can also correspondingly save the floor area occupied by the equipment, ultimately achieving a reduction in the production space cost.

[0051] Embodiment 2

[0052] As Figures 1 to 12 shown, a fully automatic milling flat mold includes an upper mold 2 and a lower mold 1. Taking the lower mold 1 as the plane reference, clamping rods 3 are provided at the four corners of its top, and clamping cylinders 4 are provided at the corresponding positions of the upper mold 2. During operation, the upper mold 2 is slidably arranged in the clamping rods 3 through the clamping cylinders 4, indirectly realizing its installation method of sliding above the lower mold 1. In the initial state, the upper mold 2 and the lower mold 1 maintain a certain distance. When the strip enters the mold, the upper mold 2 is driven to perform an action of first moving downward and then upward. During the period when the upper mold 2 moves downward to fix the strip between the two, the milling flat of the strip is completed, and then it automatically moves upward to complete the reset, while cooperating with the continuous feeding of the strip. The length of the strip is not limited in this embodiment, and for the convenience of understanding, the strip is set to the length of 1 section of finished product (i.e., the pin).

[0053] At this time, the strip needs to first complete the feeding, and after entering the mold, the cutting of the upper and lower parts is completed in sequence. The strip also needs to be limited throughout the process to avoid the deviation of the strip due to the force of the milling cutter during cutting, resulting in the lack of milling flat accuracy. Specifically, a first fixing plate 5 is provided on the top of the lower mold 1. The size of the first fixing plate 5 is smaller than that of the lower mold 1. On the upper left side of the first fixing plate 5, a feeding plate 6 is provided, that is, the strip can be fed on the left side of the mold, and the feeding method can be electric automatic or mechanical automatic to support the stable feeding of the strip. An inlet groove 7 is opened on the top of the feeding plate 6. The inlet groove 7 is a square groove with a certain depth, and its width is consistent with the strip, used to realize the inlet positioning of the strip. At the same time, a plurality of limiting blocks 10 are also provided on the top of the first fixing plate 5. The limiting blocks 10 are specifically limiting plates that are symmetric in the front and back. Therefore, a limiting groove is formed between each pair of symmetric limiting plates in the front and back, used to limit the strip entering the mold. The distance between each limiting block 10 and the feeding plate 6 is kept consistent and is greater than the length of a single strip in this embodiment, ensuring that the strip can be completely limited after entering the mold and will not deviate.

[0054] Based on the above operations, a shock absorption design is also provided between the lower die 1 and the first fixed plate 5. It can also be understood that the first fixed plate 5 is slidably arranged in the lower die 1 through a plurality of shock absorption rods, and shock absorption springs are sleeved on the shock absorption rods to absorb the vibration and stress generated when the upper die 2 impacts the lower die 1, avoiding deformation, cracking or wear of the various precision components on the lower die 1 caused by repeated impacts; at the same time, it can also reduce the dimensional deviation that may be caused by vibration, stabilize the preparation and forming process of the strip, and ensure the consistency of the finished product.

[0055] Further, a lower cutting assembly 14 and an upper cutting assembly 15 are provided at the position on the top of the first fixed plate 5 to the right of the limiting block 10. It can be understood that the purpose of this embodiment is to achieve that "the strip can be cut both above and below after entering the mold only once, so that the strip taken out of the mold can be directly sent for rolling glue or enter the next process, improving the preparation efficiency". Therefore, the front-back sequence of the lower cutting assembly 14 and the upper cutting assembly 15 is not limited. The bottom surface can be cut first, or the top surface can be cut first. As Figure 11 shown, only the layout method of cutting the bottom first and then the top is shown, and it can be replaced in actual application:

[0056] First, a second fixed plate 8 with the same size as the first fixed plate 5 and cooperating with it is provided at the bottom of the upper die 2. A lower cutting assembly 14 is provided at the position on the top of the first fixed plate 5 to the right of the rightmost limiting block 10. A first beveled push block 146 is correspondingly provided at the bottom of the second fixed plate 8. That is, when the upper die 2 moves downward, it will drive the second fixed plate 8 to move downward, and then drive the first beveled push block 146 to push the lower cutting assembly 14 to operate, completing the lower cutting of the strip;

[0057] Among them, the lower cutting assembly 14 includes: a lower cutting groove 141 is opened at the top of the first fixed plate 5. Guide plates are provided on both the left and right sides of the inner wall of the lower cutting groove 141. A first guide block 143 is slidably arranged between the guide plates. The first guide block 143 is flush with the lower cutting groove 141, and a lower cutting milling cutter 144 is installed on the front side of the first guide block 143. The blade of the lower cutting milling cutter 144 is at the highest point. A first elastic member 145 is connected between the first guide block 143 and the front side of the inner wall of the lower cutting groove 141. The first elastic member 145 is specifically a tension spring. In the initial state, the lower cutting milling cutter 144 will be suspended at the inner rear part of the lower cutting groove 141 under the tensile force of the first spring, and the cutting edge is also behind the strip. Therefore, when the rear side of the first guide block 143 is designed to be inclined, after the upper die 2 moves downward, it will drive the first beveled push block 146 to move downward into the lower cutting groove 141, and gradually squeeze the first guide block 143 to move forward, pushing the lower cutting milling cutter 144 to move forward to complete the lower cutting action of the strip. At this time, the first elastic member 145 is compressed. Then, the upper die 2 moves upward to perform a reset action, driving its subsequent linkage components to be reset. The first guide block 143 is no longer compressed, and moves backward under the tensile reset force of the first elastic member 145, and the lower cutting milling cutter 144 no longer contacts the strip.

[0058] On the top of the first fixing plate 5, at a position to the right of the lower cutting assembly 14, there is an upper cutting assembly 15. Corresponding to it, at the bottom of the second fixing plate 8, there is a second bevel push block 156. That is, when the upper die 2 moves downward, it will drive the second fixing plate 8 to move downward, and then drive the second bevel push block 156 to push the upper cutting assembly 15 to operate. The upper cutting assembly 15 includes:

[0059] On the top of the first fixing plate 5, there is an upper cutting groove 151. At the same time, at a position above the upper cutting groove 151 on the first fixing plate 5, there is a guide frame 152. Inside the guide frame 152, at the rear side, there is a second guide block 154 sliding through a second elastic member 153. The front side of the top of the second guide block 154 is also inclined. At the bottom of the second guide block 154, there is an upper cutting milling cutter 155. The blade of the upper cutting milling cutter 155 is located below. That is to say, after the upper die 2 moves downward, it drives the second bevel push block 156 to move downward into the guide frame 152, gradually squeezing the second guide block 154 to move backward. The backward movement of the second guide block 154 drives the upper cutting milling cutter 155 to move backward to complete the upper cutting action of the strip. At this time, the second elastic member 153 is compressed. Immediately afterwards, the upper die 2 moves upward to perform a reset action, driving its subsequent linkage components to perform reset actions. The second guide block 154 is no longer squeezed and moves forward under the tensile reset force of the second elastic member 153, and the upper cutting milling cutter 155 no longer contacts the strip.

[0060] Embodiment 3

[0061] As Figures 1 to 12 shown, a fully automatic milling and flattening die includes an upper die 2 and a lower die 1. On the top of the lower die 1, there are an upper cutting assembly 15 and a lower cutting assembly 14. When the upper die 2 moves downward, it pushes the upper cutting assembly 15 and the lower cutting assembly 14 to operate, realizing the upper and lower cutting of the strip. In practical applications, the preparation of pins not only has the need for upper and lower cutting. Therefore, the following components are also provided in the die, which are respectively used to realize the multi-demand application of the strip. Specifically:

[0062] Between the upper die 2 and the lower die 1, from left to right, there are: a chamfering assembly 11, a front and rear cutting assembly 12, a punching assembly 13, a lower cutting assembly 14, an upper cutting assembly 15, and a cutting-off assembly 17. And the length of the strip also conforms to the process flow and is set as a copper bar of unlimited length, etc. It can be understood that when the working distances of each component are maintained at fixed preset values and the working frequencies, after the strip enters the die, each section of the strip with a specified length will be processed in sequence.

[0063] Above, the number of the limit blocks 10 is also limited to 3, which are the first limit block 101, the second limit block 102, and the third limit block 103 from left to right in sequence.

[0064] The chamfering assembly 11 is located between the first limiting block 101 and the feeding plate 6. Specifically, a lower chamfering knife 111 is provided at the top of the first fixing plate 5 at a position to the left of the first limiting block 101. The lower chamfering knife 111 protrudes upward from the first fixing plate 5, and an upper chamfering knife 112 is correspondingly provided at the bottom of the second fixing plate 8. It can be understood that when the upper die 2 moves downward, it drives the second fixing plate 8 to move downward, and the upper chamfering knife 112 and the lower chamfering knife 111 act on the strip at the same time, leaving chamfers on the strip. The distance between the chamfers is the length of a section of the strip. Chamfering in advance can also cooperate with the subsequent cutting work to avoid the strip not being completely cut when discharging. A first limiting rod 113 is provided at the position of the second fixing plate 8 to the right of the upper chamfering knife 112. That is, when the upper chamfering knife 112 and the lower chamfering knife 111 act on the strip, the strip on its right side can be limited by the first limiting rod 113 to avoid the strip on the right side being affected and ensure the processing accuracy.

[0065] The front and rear cutting assembly 12 is located between the first limiting block 101 and the second limiting block 102. Specifically, two cutting slots 121 are formed at the top of the first fixing plate 5. The cutting slots 121 are symmetrically arranged front and back. A first integrated plate 122 is correspondingly provided at the bottom of the second fixing plate 8. Front and rear cutting knives 123 are symmetrically provided at the bottom of the first integrated plate 122. That is, when the upper die 2 moves downward, it drives the second fixing plate 8 to move downward, and the front and rear cutting knives 123 move downward to cut the front and rear sides of the strip until they enter the cutting slots 121, leaving two transverse slots on the strip to cooperate with the later rolling of the pins. A second limiting rod 124 is provided at the position of the bottom of the first integrated plate 122 to the right of the front and rear cutting knives 123. That is, when the front and rear cutting knives 123 cut the front and rear sides of the strip, the strip on its right side can be limited by the second limiting rod 124 to avoid the strip on the right side being affected and ensure the processing accuracy.

[0066] The punching assembly 13 is located between the second limiting block 102 and the third limiting block 103. Specifically, two punching limiting slots 131 are formed at the top of the first fixing plate 5. The punching limiting slots 131 are symmetrically arranged front and back. A second integrated plate 132 is symmetrically provided at the bottom of the second fixing plate 8. A punching needle 133 is provided on the left side of the bottom of the second integrated plate 132. That is, when the upper die 2 moves downward, it drives the second fixing plate 8 to move downward, and the punching needle 133 moves downward to punch the strip at a specified position to meet different types of electrical, mechanical or assembly requirements. Third limiting rods 134 are symmetrically provided at the position of the bottom of the second integrated plate 132 to the right of the punching needle 133. That is, when the punching needle 133 starts to punch the strip, the third limiting rods 134 will gradually insert into the punching limiting slots 131 to realize the limitation of the strip and ensure the processing accuracy.

[0067] The cutting component 17 is located at the rightmost side of the mold. Specifically, a cutting groove 171 is formed on the top right side of the first fixing plate 5. A receiving block 172 is arranged in the cutting groove 171. Third bevel push blocks 173 are symmetrically arranged on the top right side of the receiving plate. A discharge channel 174 is formed between the third bevel push blocks 173. Correspondingly, fourth integrated plates 175 are symmetrically arranged at the bottom of the second fixing plate 8. A cutting knife 176 is arranged at the bottom of the fourth integrated plate 175. The inclination angle of the cutting knife 176 intersects with the third bevel push blocks 173. That is, the strip that has completed all processing steps will move to the right in the mold until the cut corner is above the third bevel push blocks 173. At this time, when the upper mold 2 moves downward to drive the cutting knife 176 to move downward, it will push the cut corner to bend downward along the third bevel push blocks 173 until the cut corner reaches the top of the receiving block 172, completely cutting the strip. A fourth limiting rod 177 is arranged at the bottom of the fourth integrated plate 175 on the left side of the cutting knife 176. That is, when the upper mold 2 moves downward, it will also drive the fourth limiting rod 177 to move downward, limiting the left strip between the fourth limiting rod 177 and the first fixing plate 5 to prevent the left strip from being affected and resulting in poor processing quality.

[0068] An outlet groove 9 is extended and arranged at the top of the first fixing plate 5 at the right side of the cutting groove 171. The outlet groove 9 is specifically arranged as an inclined opening to the right. Then, after the cutting knife 176 completely cuts the right strip, it can directly slide out of the mold through the right outlet groove 9 for collection.

[0069] Furthermore, a lower cutting limiting groove 147 is arranged at the top of the first fixing plate 5 at the front side of the first bevel push block 146 for multi-directional limiting when the lower cutting milling cutter 144 acts on the strip. A "cross" groove is formed at the bottom of the lower cutting limiting groove 147. The horizontal groove of the "cross" groove is used to limit the strip, and the vertical groove is used to limit the lower cutting milling cutter 144 moving forward and backward. A first positioning pin 148 is arranged at the top of the first fixing plate 5 at the left side of the lower cutting limiting groove 147 for limiting the left strip when the lower cutting milling cutter 144 acts on the strip to prevent the left strip from being affected.

[0070] Correspondingly, first limiting grooves 161 are provided on both the left and right sides at the bottom of the guide frame 152. The first limiting grooves 161 are mainly used for limiting the strip entering the guide frame 152 to prevent the strip from shifting when the upper cutting and milling cutter 155 acts on the strip. It further includes: two second limiting grooves 162 are provided at the position on the top of the first fixing plate 5 on the right side of the guide frame 152. The second limiting grooves 162 are symmetrically arranged front and back. Correspondingly, a third integrated plate 163 is provided at the bottom of the second fixing plate 8, a second positioning pin 164 is provided at the bottom of the third integrated plate 163, and fifth limiting rods 165 are provided on both the front and back sides of the third integrated plate 163. That is, when the upper die 2 moves downward, it drives the second fixing plate 8 to move downward. The fifth limiting rods 165 move downward and are inserted into the second limiting grooves 162 to preliminarily limit the strip, and at the same time, the second positioning pin 164 moves downward and is inserted into the punching hole of the strip to achieve enhanced limiting of the strip. The two cooperate to limit the strip on the right side when the upper cutting and milling cutter 155 acts on the strip to prevent the strip on the right side from being affected.

[0071] A fifth integrated plate 178 is further provided at the bottom of the second fixing plate 8. Correspondingly, a cutting limiting groove 179 is provided at the top of the first fixing plate 5. A "cross" groove is opened at the bottom of the cutting limiting groove 179. The horizontal groove of the "cross" groove is used to limit the strip. When the upper die 2 moves downward, it drives the fifth integrated plate 178 to be inserted into the "cross" groove to limit most of the area above the strip. It can be understood that when the cut corners of the strip are squeezed and cut off, the strips on both the left and right sides will tend to swing upward. The strip on the right side can directly enter and exit the feeding groove 9 and slide out for material collection, while the strip on the left side needs to be stably limited to prevent the strip on the left side from deforming due to the upward swing under force, increasing the probability of defective products.

[0072] Embodiment 4

[0073] To further elaborate on the operation process of the present invention, in this embodiment, taking the length defined by the chamfering assembly 11 as the base number, the continuously entering strip will be divided into multiple equal parts such as a / b / c / d, specifically:

[0074] The strip enters the mold through the feeding groove 7 until its right end is inserted into the first limiting block 101. Then, the upper die 2 performs a driving operation to drive the chamfering assembly 11 to perform a chamfering on the strip once. The section between the first chamfering point and the rightmost end of the strip is section a;

[0075] The strip continues to move into the mold. Section a moves between the first limiting block 101 and the second limiting block 102. The upper die 2 performs a driving operation. The front and back cutting assembly 12 completes the front and back cuts on section a, and at the same time, the chamfering assembly 11 performs a second chamfering on the strip. The section between the second chamfering point and the first chamfering point is section b;

[0076] The strip continues to move into the mold. Section a moves between the second limit block 102 and the third limit block 103, and section b moves between the first limit block 101 and the second limit block 102. The upper die 2 performs a driving operation once. The punching component 13 completes the punching of section a, the front and rear cutting component 12 completes the front and rear cuts of section b, and at the same time, the corner cutting component 11 performs three corner cuts on the strip. The section between the third corner cutting point and the second corner cutting point is section c.

[0077] The strip continues to move into the mold. Section a moves between the third limit block 103 and the upper cutting component 15, section b moves between the second limit block 102 and the third limit block 103, and section c moves between the first limit block 101 and the second limit block 102. The upper die 2 performs a driving operation once. The upper cutting component 15 completes the upper cut of section a, the punching component 13 completes the punching of section b, the front and rear cutting component 12 completes the front and rear cuts of section c, and at the same time, the corner cutting component 11 performs three corner cuts on the strip. The section between the fourth corner cutting point and the third corner cutting point is section d, and so on. During this period, each limit component realizes the sequential limitation of the strip in different working positions and different states.

[0078] In this way, the automatic loading machine only needs to realize the stable loading of the strip, so that the strip enters different processing positions in the mold of the present invention. By continuously driving the upper die 2, the full-automatic processing of the strip is completed.

[0079] Embodiment 5

[0080] In another embodiment, as Figure 6 shown, a plurality of rounded corner grooves 19 are also provided at the top of the first fixing plate 5. Rounded corner cutters 20 are rotatably provided in the rounded corner grooves 19, and the rounded corner cutters 20 slightly protrude from the first fixing plate 5. That is, for the preparation requirements of different strip materials, when the upper die 2 moves downward, it can drive the strip to move downward and act on the rounded corner cutters 20. At this time, the rounded corner cutters 20 rotate to polish and round the round holes on the strip, reduce the generation of metal burrs, and at the same time can reduce stress concentration and extend the service life of the finished product.
