Description
Technical Field
[0001] The utility model belongs to the technical field of progressive dies, and particularly relates to a feeding and positioning component of a progressive die. Background Art
[0002] A progressive die is a special die used for metal stamping. The progressive die mainly consists of an upper die, a lower die, a guide post, etc. During the working process, the upper die and the lower die move alternately to complete the stamping process, thereby gradually stamping the metal material into the required shape. The design and manufacture of the progressive die need to consider factors such as the size, shape, and processing procedures of the workpiece to ensure that the workpiece can be smoothly processed through each process in the die. When stamping the workpiece, it is difficult to accurately position the workpiece during the feeding process of the feeding belt, which results in the workpiece being unable to accurately stay within the stamping range of the progressive die, thereby affecting the processing accuracy and quality. Secondly, due to the inaccurate position of the workpiece, it may cause the product size and shape to not meet the requirements, resulting in a decline in product quality, more scrap products, and an increase in production costs. Therefore, it is desired to develop a new structure to solve the above problems. Summary of the Utility Model
[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a feeding and positioning component of a progressive die.
[0004] The utility model is realized through the following technical solutions: A feeding and positioning component of a progressive die, comprising: an upper die of the progressive die, a lower die of the progressive die, and a positioning mechanism. The lower die of the progressive die is arranged below the upper die of the progressive die, and the positioning mechanism is arranged in front of the lower die of the progressive die. A feeding belt is arranged at the center of the upper surface of the positioning mechanism;
[0005] A set of induction pressure grooves are formed by recessing downward at the center of the upper surface of the lower die of the progressive die. An induction pressure plate is arranged inside the induction pressure grooves. Insertion rods are arranged on the left and right sides of the front surface of the lower die of the progressive die. An electrode I is installed on the front surface of each group of insertion rods. Installation grooves are respectively opened on the left and right sides of the lower die of the progressive die;
[0006] The rear side of the positioning mechanism is of a C-shaped opening structure. Slots are respectively opened on the left and right sides of the rear side of the positioning mechanism. An electrode II is arranged inside each group of slots. An induction box is arranged on the left side of the top of the positioning mechanism. A probe is arranged inside the induction box. Installation strips are respectively arranged on the left and right sides of the slots. Four groups of knobs are arranged on the left and right sides of the positioning mechanism.
[0007] As a preferred embodiment, four groups of return springs are equidistantly arranged between the top of the induction pressure grooves and the bottom of the induction pressure plate. A pressure sensor is arranged at the center of the bottom of the induction pressure grooves. The pressure sensor is connected to the electrode I through a wire I.
[0008] As a preferred embodiment, a signal receiving module and an intelligent control module are provided inside the induction box. The signal receiving module is connected to an external control mechanism. The induction box is connected to the second electrode through the second wire. A power supply module is provided inside the positioning mechanism, and the power supply module is connected to the induction box through the third wire.
[0009] As a preferred embodiment, several groups of continuous metal gasket raw materials are provided on the upper surface of the conveyor belt. A connecting piece is provided between every two groups of metal gasket raw materials. A group of induction bumps are provided on the left and right sides of the top of each group of connecting pieces.
[0010] As a preferred embodiment, the shortest distance from the left induction bump to the induction box is less than the length of the probe, and the horizontal height of the induction bump is greater than the horizontal height of the probe. After the probe no longer touches the induction bump, the signal receiving module controls the external control mechanism to control the upper die of the progressive die to move upward, thereby relieving the pressure on the induction pressing plate. The four reset springs rebound to push the induction pressing plate upward, so that the pressure sensor is no longer under pressure. When the pressure of the pressure sensor changes, the signal is transmitted to the signal receiving module again, and the probe is controlled to extend through the intelligent control module. When the probe touches the induction bump again, the signal receiving module receives the signal, and the external control mechanism is used to control the upper die of the progressive die to perform the second stamping operation. Repeating this process can achieve accurate positioning of the metal gasket raw materials and accurate control of the stamping timing, improve production efficiency, reduce the generation of defective products, and thus reduce production costs.
[0011] As a preferred embodiment, a screwing rod is provided on one side of the knob close to the positioning mechanism. Two screwing grooves II are respectively opened on the left and right sides at the rear of the positioning mechanism. Two screwing grooves I are respectively opened on the left and right sides of the lower die of the progressive die. Threads are provided on the outer side of the screwing rod. An internal thread groove I is opened inside the screwing groove I, and an internal thread groove II is opened inside the screwing groove II.
[0012] As a preferred embodiment, the radius lengths of the screwing groove I and the screwing groove II are the same. The radius length of the screwing rod is less than the radius lengths of the screwing groove I and the screwing groove II. The length of the screwing rod is greater than the total length of the screwing groove I and the screwing groove II. During actual use, rotate the four knobs respectively to make the four rotating rods rotate and disengage from the inside of the four screwing grooves I and the four screwing grooves II. Then hold the positioning mechanism and pull the positioning mechanism forward, so that the two mounting strips slide forward and disengage from the inside of the two mounting grooves, and at the same time the two inserting rods disengage from the inside of the two inserting slots, and then the positioning mechanism can be disassembled from the front of the progressive die, and the positioning mechanism can be maintained and replaced. It is convenient to use and simple to operate, improving work efficiency.
[0013] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By setting a positioning mechanism, an induction box, a probe, induction bumps, and an induction pressing plate, the extension and retraction of the probe can be controlled according to the pressure change when the upper die and the lower die of the progressive die stamp the metal gasket raw material, so as to control the contact and separation between the probe and the induction bumps, and then accurately position the position of the metal gasket raw material and the stamping timing of the upper die of the progressive die. Furthermore, the production quality can be improved, the number of defective products can be reduced, and the production cost can be saved. By setting a knob, a rotating rod, a first rotating groove, and a second rotating groove, the installation and disassembly between the positioning mechanism and the lower die of the progressive die can be realized through the rotation and separation of the rotating rod and the first and second rotating grooves, which is convenient for the installation and use of the positioning mechanism, and is also convenient for maintenance and replacement.

An electrode one 180 is installed on the front surface of each group of insertion rods 170. Installation grooves 210 are formed on the left and right sides of the progressive die lower die 110 respectively;
[0023] The rear side of the positioning mechanism 120 is a C-shaped opening structure. Slots 190 are formed on the left and right sides of the rear side of the positioning mechanism 120 respectively. An electrode two 200 is provided inside each group of slots 190. An induction box 140 is provided on the left side of the top of the positioning mechanism 120.

[0024] Four groups of reset springs are equidistantly provided between the top of the induction pressure grooves and the bottom of the induction pressure plate 260. A pressure sensor is provided at the center of the bottom of the induction pressure grooves. The pressure sensor is connected to the electrode one 180 through a wire one.
[0025] A signal receiving module and an intelligent control module are provided inside the induction box 140. The signal receiving module is connected to an external control mechanism. The induction box 140 is connected to the electrode two 200 through a wire two. A power supply module is provided inside the positioning mechanism 120. The power supply module is connected to the induction box 140 through a wire three.
[0026] A number of groups of continuous-structured metal gasket raw materials are provided on the upper surface of the feeding belt 130. A connecting piece is provided between every two groups of metal gasket raw materials. A group of induction bumps 160 are provided on the left and right sides of the top of each group of connecting pieces.
[0027] The shortest distance from the left induction bump 160 to the induction box 140 is less than the length of the probe, and the horizontal height of the induction bump 160 is greater than the horizontal height of the probe. After the probe no longer touches the induction bump 160, the signal receiving module controls the external control mechanism to move the progressive die upper die 100 upward, thereby relieving the pressure on the induction pressure plate 260. The four reset springs rebound and push the induction pressure plate 260 upward, so that the pressure sensor is no longer under pressure. When the pressure of the pressure sensor changes, the signal is transmitted to the signal receiving module again, and the probe is controlled to extend through the intelligent control module. When the probe touches the induction bump 160 again, the signal receiving module receives the signal, and the progressive die upper die 100 is controlled by the external control mechanism to perform the second stamping operation. By repeating this process, accurate positioning of the metal gasket raw material and accurate control of the stamping timing can be achieved, improving production efficiency, reducing the generation of defective products, and thus reducing production costs.
[0028] A screwing rod 240 is provided on one side of the knob 150 close to the positioning mechanism 120. Two sets of screwing grooves II 250 are respectively opened on the left and right sides at the rear of the positioning mechanism 120, and two sets of screwing grooves I 220 are respectively opened on the left and right sides of the progressive die lower die 110. Threads are provided on the outer side of the screwing rod 240, an internal thread groove I is opened inside the screwing groove I 220, and an internal thread groove II is opened inside the screwing groove II 250.
[0029] The radius lengths of the screwing groove I 220 and the screwing groove II 250 are the same. The radius length of the screwing rod 240 is less than the radius lengths of the screwing groove I 220 and the screwing groove II 250, and the length of the screwing rod 240 is greater than the total length of the screwing groove I 220 and the screwing groove II 250. During actual use, the four knobs 150 are respectively rotated to make the four rotating rods rotate and disengage from the four screwing grooves I 220 and the four screwing grooves II 250. Then, hold the positioning mechanism 120 and pull the positioning mechanism 120 forward, so that the two mounting strips 230 slide forward and disengage from the two mounting grooves 210. At the same time, the two inserting rods 170 disengage from the two inserting slots 190, and then the positioning mechanism 120 is disassembled from the front of the progressive die, and the positioning mechanism 120 can be maintained and replaced. It is convenient to use and simple to operate, improving work efficiency.
[0030] Example 1: Please refer to Figures 1 to 4, during actual use, first insert the two sets of mounting bars 230 along the two sets of mounting grooves 210 and push them backward, so that the rear side of the positioning mechanism 120 is inserted backward outside the lower die 110 of the progressive die. At this time, the two sets of insertion rods 170 are inserted forward into the two sets of insertion slots 190, and the two sets of electrode ones 180 and the two sets of electrode twos 200 are in contact. Then rotate the four sets of knobs 150 respectively, so that the four sets of rotary connecting rods 240 rotate backward along the four sets of rotary connecting grooves two 250 and are inserted into the four sets of rotary connecting grooves one 220. Continue to rotate the four sets of knobs 150 to make the four sets of rotary connecting rods 240 rotatably connected tightly with the four sets of rotary connecting grooves one 220, thus completing the installation of the positioning mechanism 120 and the lower die 110 of the progressive die, and the installation is simple;
[0031] When performing stamping work, the feeding belt 130 drives the metal gasket raw material to move backward, and conveys the metal gasket raw material backward into the space between the upper die 100 of the progressive die and the lower die 110 of the progressive die for stamping and forming. When the probe contacts the induction bump 160, the signal receiving module senses the contact signal, and controls the upper die 100 of the progressive die to stamp the lower die 110 of the progressive die through an external control mechanism, thereby stamping and forming the metal gasket. When the upper die 100 of the progressive die is stamping, the induction pressing plate 260 moves downward and presses the pressure sensor, and the pressure sensor transmits the pressure signal to the signal receiving module. The signal receiving module transmits the control instruction to the intelligent control module and controls the probe to retract into the induction box 140;
[0032] When the probe no longer contacts the induction bump 160, the signal receiving module controls the external control mechanism to control the upper die 100 of the progressive die to move upward, thereby relieving the pressure on the induction pressing plate 260. The four sets of return springs rebound and push the induction pressing plate 260 upward, so that the pressure sensor is no longer under pressure. When the pressure of the pressure sensor changes, the signal is transmitted to the signal receiving module again, and the probe is controlled to extend through the intelligent control module. When the probe contacts the induction bump 160 again, the signal receiving module receives the signal, and controls the upper die 100 of the progressive die to perform the second stamping work through the external control mechanism. In this way, accurate positioning of the metal gasket raw material and accurate control of the stamping timing can be achieved, the production efficiency can be improved, the generation of defective products can be reduced, and thus the production cost can be reduced.
[0033] Example 2: Please refer to Figures 1 to 3, when maintenance of the positioning mechanism 120 is required, the four groups of knobs 150 can be rotated respectively according to the above steps, so that the four groups of rotating rods rotate and disengage from the inside of the four groups of first rotating connection grooves 220 and the four groups of second rotating connection grooves 250. Then, hold the positioning mechanism 120 and pull the positioning mechanism 120 forward, so that the two groups of mounting strips 230 slide forward and disengage from the inside of the two groups of mounting grooves 210. At the same time, the two groups of insertion rods 170 disengage from the inside of the two groups of insertion slots 190. Then, the positioning mechanism 120 is disassembled from the front of the progressive die, and the positioning mechanism 120 can be maintained and replaced. It is convenient to use and simple to operate, improving work efficiency.
[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
