Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a self-detaching mode stamping die for processing hardware accessories. Background Art

[0002] When processing some hardware accessories, stamping dies are needed to stamp the hardware accessories into specific structures and shapes so that the hardware accessories can meet different usage requirements. At present, there are still some problems when using stamping dies on the market, such as:

[0003] The patent name disclosed in the prior art with application number "CN202010135031.3" is "A hot stamping hardware mold", which discloses that the fully heated stamping part is placed on the upper side of the die table, so that the stamping part is clamped between the two baffles, and the inner side edge of the stamping part should be close to the baffle. After the operation is completed, the stamping equipment is controlled to start, and the cylinder piston rod pushes the upper template to move downward, and the distance between the upper template and the mold shell is shortened, so that the No. 2 spring is compressed, and the upper boss pushes the stamping part, the die table, the slider and the lower slide plate to move downward. The No. 1 spring is compressed, and when the lower slide plate slides to the bottom wall of the guide slide groove, the stamping part, the die table, the slider and the lower slide plate stop moving, and the die groove wall can be bent for the first time along the side of the stamping part, and the two sides of the stamping part can form a 90-degree bend between the die groove wall and the upper boss, so that the stamping part forms an inverted "concave"-shaped workpiece;

[0004] The patent name disclosed in the prior art with application number "CN202210798601.6" is "A precision metal stamping die with a protective structure and convenient for automatic demoulding". It discloses that the electric push rod is first connected to the power supply and controlled by the control switch, and then the hardware to be stamped is placed on the top of the forming block. By starting the power mechanism, the forming plate can be pushed to move downward. At the same time, the pressing plate and the positioning block will fix the hardware. The hardware is positioned by the right-angle plate. The movement of the forming plate can drive the protective card plate to move downward, and the protective card plate will contact the left and right sides of the lower mold until the extrusion column and the hardware are pressed into the inside of the forming groove. When the hardware is demoulded, the lifting plate can be pushed upward by starting the electric push rod. With the movement of the lifting plate, the ejector rod can be moved up and down inside the positioning hole. Since the ejector rod does not eject from the inside of the positioning hole, the demoulding of the hardware is completed.

[0005] When the stamping die is in use, the electric push rod is started to control the lifting plate to move upward, so that the ejector moves up and down in the positioning hole to demould the hardware, so that the hardware can be automatically demoulded. However, when the entire stamping die needs to be automatically demoulded, the electric push rod needs to be started. If the electric push rod is damaged, the automatic demoulding cannot be performed well. At the same time, using the electric push rod to control the demoulding will also make the use cost of the entire stamping die higher;

[0006] Therefore, we proposed a self-release mode stamping die for hardware accessories processing in order to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a self-demolding mode stamping die for hardware accessories processing, so as to solve the problem raised by the above-mentioned background technology that the stamping dies currently on the market need to start an electric push rod when they need automatic demolding. If the electric push rod is damaged, the automatic demolding cannot be performed well. At the same time, using the electric push rod to control the demolding will also increase the cost of using the entire stamping die.

[0008] To achieve the above object, the present invention provides the following technical solution: a self-release mode stamping die for processing hardware accessories, comprising a lower die base, and a concave die plate installed above the lower die base;

[0012] A bidirectional screw is installed in a groove on the front side of the vertical plate, an adjustment block is connected to the outside of the bidirectional screw, an adjustment rod is rotatably connected to the front side of the adjustment block, a self-demolding mechanism is rotatably connected to the front side of the adjustment rod, and the self-demolding mechanism is arranged in the space between the two concave die grooves;

[0013] A main regulating block is installed at the lower rear side of the upper die seat, and the main regulating block is arranged above the convex block.

[0014] Preferably, the highest point of the self-demolding mechanism is lower than the highest point of the concave die plate, and the two concave die grooves are respectively arranged on the left and right sides of the lower punch, and the left and right side surfaces of the lower punch after rising are in contact with one side surface of the concave die groove.

[0015] Through the above-mentioned structural setting, the lower punch, the die groove and the upper punch cooperate with each other in the later stage, so that the middle part of the hardware accessories can be well punched into a "W" shape structure to meet the shape requirements of the hardware accessories when they are used.

[0016] Preferably, two limiting sliding grooves are symmetrically provided on the upper surface of the rear side of the concave template;

[0017] Limiting slide blocks are installed below the left and right sides of the vertical plate, the front end of the limiting slide block is connected with the connecting spring, and the bottom of the limiting slide block and the connecting spring are both arranged in the limiting sliding groove.

[0018] Through the above-mentioned structural arrangement, the sliding of the limiting sliding block in the limiting sliding groove can ensure that the vertical plate slides stably on the upper surface of the concave template.

[0019] Preferably, a first vortex spring is nested and connected to the outer side of the left end of the bidirectional screw rod, and a connecting rope is wrapped around the outer side of the right end of the bidirectional screw rod. The lower end of the connecting rope is connected to the upper surface of the concave template through a guide wheel, and the guide wheel is installed on the upper surface of the concave template.

[0020] Through the above-mentioned structural setting, the stored force of the first vortex spring can automatically drive the bidirectional lead screw to rotate in the opposite direction in the later stage, so that the bidirectional lead screw can well wind up the lower end of the connecting rope for the next use.

[0021] Preferably, the lower part of the main regulating block is an inclined surface, and the protrusion forms a front-to-back sliding structure through the main regulating block.

[0022] Through the above-mentioned structural setting, when the main regulating block with an inclined surface below descends, it will exert a forward thrust on the protrusion, without the need to use an additional power source, with a simple structure and easy operation.

[0023] Preferably, the lifting control assembly comprises an electric push rod installed in a groove in the middle of the concave mold plate, and the output end of the electric push rod is connected to the lower punch.

[0024] Through the above structural arrangement, the output end of the electric push rod can well drive the lower punch to move up and down, so that the lower punch can well perform stamping operations on the hardware accessories.

[0025] Preferably, two guide grooves are symmetrically provided on the upper surface of the rear side of the concave template, the guide grooves are arranged in an inclined shape, and a limiting sliding groove is arranged on the outer side of the guide groove.

[0026] Through the above-mentioned structural setting, the guide groove arranged in an inclined shape can guide and limit the movement of the connecting column.

[0027] Preferably, a cross bar is installed in a symmetrical groove inside the front side of the vertical plate, a connecting column is slidably connected to the outer side of the cross bar, a vertical bar is installed below the connecting column, and the lower end of the vertical bar is inserted into the guide groove;

[0028] A self-positioning rod is installed at the front end of the connecting column, and the front end of the self-positioning rod is arranged on the concave template;

[0029] The diameter of the self-aligning rod is smaller than the thickness of the hardware.

[0030] Through the above structural setting, the vertical rod can drive the self-positioning rod to move forward and inward at the same time, so that the two self-positioning rods can cooperate with each other to self-position the hardware accessories on the concave template, so as to facilitate the subsequent stamping operation of the hardware accessories.

[0031] Preferably, a sub-regulating block is installed at the lower end of the main regulating block, and there is a distance between the sub-regulating block and the protruding block.

[0032] Through the above-mentioned structural setting, the main regulating block can drive the auxiliary regulating block to rise and fall together, so that the auxiliary regulating block can apply a downward thrust to the push plate in the later stage. Due to the spacing between the auxiliary regulating block and the protrusion, the auxiliary regulating block will not affect the protrusion when rising and falling.

[0033] Preferably, the lifting control assembly comprises a push plate installed in a groove opened in the middle of the concave template, a rotating rod is installed through the outer side of the push plate, both ends of the rotating rod are rotatably connected to the inside of the concave template, and a second vortex spring is connected to the outer side of one end of the rotating rod;

[0034] The rear end of the push plate passes through the rear side of the concave mold plate, and the front end of the push plate is arranged below the lower convex mold;

[0035] The lower part of the lower punch is connected to the inside of the concave die plate through a return spring;

[0036] The auxiliary regulating block is arranged above the rear end of the pushing plate, and the pushing plate forms a rotating structure through the auxiliary regulating block.

[0037] Through the above-mentioned structural arrangement, the push plate can well drive the lower punch to move upward when rotating, so that the lower punch can be driven to move up and down without using an additional power source, and the operation is convenient.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-demolding mode stamping die for hardware accessories processing, the self-demolding mechanism quickly applies a forward thrust to the hardware after stamping in the die groove, so that the hardware can be self-demolded well, and no power source is needed, which not only does not affect the self-demolding operation, but also reduces the use cost of the entire stamping die. The specific contents are as follows:

[0039] When the upper punch moves upward after stamping, the lower punch moves downward. When the main regulating block moves upward and separates from the protrusion, the vertical plate is automatically driven to move backward by the stored force of the connecting spring. At this time, the pulling force on the connecting rope is lost, and the stored force of the first vortex spring can automatically drive the bidirectional screw to rotate in the opposite direction, thereby causing the regulating block to move in the opposite direction, so that the regulating rod moves from an inclined state to a vertical state, so that the vertical regulating rod drives the self-demolding mechanism to move forward quickly, and then the self-demolding mechanism quickly applies a forward thrust to the hardware after stamping in the die groove, so that the hardware is well separated from the die groove for self-demolding, and no additional power source is needed, which not only does not affect the self-demolding operation, but also reduces the use cost of the entire stamping die;

[0040] When the upper punch moves downward for stamping operation, the convex block and the vertical plate can be automatically pushed forward by the inclined surface under the main regulating block. When the vertical plate moves forward, one end of the connecting rope can be pulled, and then the connecting rope automatically drives the bidirectional screw rod to rotate, so that the bidirectional screw rod drives the regulating block to move outward when rotating, so that the regulating block drives the regulating rod to be inclined, and then the regulating rod drives the self-demolding mechanism to separate from the die groove to avoid affecting the later stamping operation;

[0041] Furthermore, when the vertical plate moves forward, the vertical rod moves in the guide groove through the inclined guide groove, so that the vertical rod drives the self-positioning rod to move inward, so that the two symmetrically arranged self-positioning rods cooperate to self-position the hardware accessories, so that the center of the hardware and the center of the upper punch are on the same vertical line, ensuring the accuracy of the stamping position, and facilitating the improvement of the qualified rate of the hardware accessories after stamping in the later stage;

[0042] The lifting control component is an electric push rod, which can automatically drive the lower punch to lift and lower for stamping operations;

[0043] The lifting control component is a push plate, which applies a downward thrust to the rear end of the push plate by descending the auxiliary control block, so that the push plate rotates with the rotating rod as the center, thereby making the front end of the push plate apply an upward thrust to the lower punch. Therefore, there is no need to use a power source, and the lower punch can be driven to perform up and down lifting operations well. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] See also Figure 1-Figure 12 , the present invention provides the following technical solutions:

[0059] Embodiment 1: The self-release mode stamping die for processing hardware accessories in this embodiment can automatically demould the hardware accessories after stamping without using a power source when the upper punch 5 is raised after stamping, thereby reducing the use cost of the stamping die. For the specific structure, refer to the attached Figure 1-Figure 9 As shown, it includes a lower die base 1 and a concave die plate 2 installed above the lower die base 1, the upper four corners of the lower die base 1 are connected to the upper die base 4 through a guide column assembly 3, an upper punch 5 is installed on the lower surface of the upper die base 4, a lower punch 13 is arranged in a groove in the middle of the concave die plate 2, two concave die grooves 6 are symmetrically arranged in the upper surface of the concave die plate 2, a lifting control assembly is arranged below the lower punch 13, a vertical plate 7 is connected to the upper rear side of the concave die plate 2, a convex block 10 is installed on the rear side of the vertical plate 7, a bidirectional screw rod 16 is installed in a groove in the front side of the vertical plate 7, an adjusting block 121 is connected to the outer side of the bidirectional screw rod 16, the front side of the adjusting block 121 is rotatably connected to an adjusting rod 12, the front side of the adjusting rod 12 is rotatably connected to a self-demolding mechanism 8, and the self-demolding mechanism 8 is arranged in the space between the two concave die grooves 6, a main regulating block 11 is installed at the lower rear side of the upper die base 4, and the main regulating block 11 is arranged above the convex block 10.

[0060] The highest point of the demoulding mechanism 8 is lower than the highest point of the concave mold plate 2. The two concave mold grooves 6 are respectively arranged on the left and right sides of the lower punch 13. After the lower punch 13 rises, the left and right side surfaces are in contact with one side of the concave mold groove 6. Two limit slide grooves 202 are symmetrically opened on the upper surface of the rear side of the concave mold plate 2. Limit slide blocks 71 are installed below the left and right sides of the vertical plate 7. The front end of the limit slide block 71 is connected to the connecting spring 72. The bottom of the limit slide block 71 and the connecting spring 72 are both arranged in the limit slide groove 202. The bidirectional screw rod The left end of 16 is nested and connected with a first vortex spring 161, the right end of the bidirectional screw rod 16 is wrapped and connected with a connecting rope 17, the guide wheel is installed on the upper surface of the concave template 2, the lower end of the connecting rope 17 is connected to the upper surface of the concave template 2 through the guide wheel, the lower part of the main regulating block 11 is an inclined surface, the protrusion 10 forms a front and rear sliding structure through the main regulating block 11, and the lifting control assembly includes an electric push rod 14 installed in a groove inside the middle of the concave template 2, and the output end of the electric push rod 14 is connected to the lower punch 13.

[0061] First, place the hardware accessories to be stamped on the concave mold plate 2. At this time, the self-demolding mechanism 8 is in the space between the two concave mold grooves 6 below the hardware accessories. Then, the upper mold base 4 is driven to move downward by the external lifting mechanism, and then the upper mold base 4 drives the upper punch 5 to move downward. At this time, the guide column assemblies 3 set at all four corners can ensure that the upper mold base 4 and the upper punch 5 move downward stably. At this time, the upper mold base 4 drives the main regulating block 11 on the rear side to move downward together. At this time, the inclined surface on the lower side of the main regulating block 11 contacts the convex block 10, and at the same time, a The forward thrust, at this time, the protrusion 10 drives the vertical plate 7 to move forward, and the limiting sliders 71 on the bottom surfaces of the left and right sides of the vertical plate 7 slide forward stably in the limiting slide groove 202, and at the same time squeeze and store force on the connecting spring 72 in the limiting slide groove 202. Since the lower end of the connecting rope 17 is connected to the upper surface of the concave template 2, when the vertical plate 7 moves forward, the connecting rope 17 will be pulled through the cooperation of the guide wheel, and then the other end of the connecting rope 17 automatically drives the two-way screw rod 16 to rotate, and the first vortex spring 161 stores force when the two-way screw rod 16 rotates.

[0062] When the bidirectional screw rod 16 rotates, it drives the adjusting block 121 connected to the outer thread to move outward. At this time, when the adjusting block 121 moves outward, it pulls the adjusting rod 12 backward, so that the adjusting rod 12 moves from a vertical state to an inclined state. At this time, the adjusting rod 12 pulls the self-demolding mechanism 8 backward, so that the self-demolding mechanism 8 is separated from the die groove 6. At this time, the self-demolding mechanism 8 is close to the front side of the vertical plate 7. At this time, the vertical surface of the front side of the main adjusting block 11 is in contact with the protrusion 10, so that when the main adjusting block 11 continues to move downward, the stability of the protrusion 10 can be guaranteed to prevent the protrusion 10 from moving backward.

[0063] Then, when the upper punch 5 continues to descend and contacts the upper surface of the hardware accessories below, the electric push rod 14 in the lifting control assembly is started, and the output end of the electric push rod 14 drives the lower punch 13 to move upward. At this time, the upper punch 5 moves downward to cooperate with the lower punch 13 to move upward, and the hardware is well stamped, so that the two ends of the hardware accessories are horizontal and the middle part is "W" shaped, thereby meeting the later use requirements.

[0064] After the stamping is completed, the upper die seat 4 drives the upper punch 5 and the main regulating block 11 to move upward. At this time, the output end of the electric push rod 14 drives the lower punch 13 to move downward, so that the lower punch 13 enters the groove in the concave die plate 2, so that the highest point of the lower punch 13 is lower than the lowest point of the concave die groove 6. Then the main regulating block 11 continues to move upward to separate from the convex block 10. At this time, the limit slider 71 and the vertical plate 7 can be automatically driven to move backward through the stored force of the connecting spring 72. At this time, the bidirectional screw rod 16 is automatically driven to rotate in the opposite direction through the stored force of the first vortex spring 161, as shown above. Similarly, when the bidirectional screw rod 16 rotates in the opposite direction, it drives the outer adjustment The block 121 moves inward, and the adjusting block 121 drives the adjusting rod 12 to move from an inclined state to a vertical state. The adjusting rod 12 drives the self-demolding mechanism 8 to move forward. The self-demolding mechanism 8 applies a forward thrust to the stamped hardware accessories in the die groove 6. Therefore, the stamped hardware accessories in the hardware accessories can be pushed forward from the die groove 6, which is convenient for automatically demolding the stamped hardware accessories. At this time, the inclined surface on the front side of the concave template 2 can also assist in separating the stamped hardware accessories from the concave template 2, so that the stamped hardware accessories can fall into the collection frame placed on the front side of the concave template 2 for collection and placement.

[0065] Then the next stamping operation can be carried out, and this process can be repeated, so that the stamping die can automatically demould the stamped hardware accessories without the need for a power source, thereby facilitating the stamping operation.

[0066] Embodiment 2: The self-release mode stamping die for hardware accessories processing in this embodiment can automatically position the hardware accessories on the basis of embodiment 1, ensuring that the center of the hardware accessories and the center of the upper punch 5 are on the same vertical line, thereby ensuring the accuracy of the stamping position, which is convenient for improving the qualified rate of the hardware accessories after stamping in the later stage. The specific structure is shown in the attached Figure 3 , Attachment Figure 5-Figure 8 Shown and attached Fig.10As shown, two guide grooves 201 are symmetrically provided on the upper surface of the rear side of the concave template 2, and the guide grooves 201 are arranged in an inclined shape. A limited sliding groove 202 is arranged on the outer side of the guide groove 201, and a cross bar 152 is symmetrically grooved inside the front side of the vertical plate 7 to install a cross bar 152, and a connecting column 151 is slidably connected to the outer side of the cross bar 152. A vertical rod 15 is installed below the connecting column 151, and the lower end of the vertical rod 15 is inserted into the guide groove 201. A self-positioning rod 9 is installed at the front end of the connecting column 151. The front end of the self-positioning rod 9 is arranged on the concave template 2, and the diameter of the self-positioning rod 9 is smaller than the thickness of the hardware accessories. When the protrusion 10 drives the vertical plate 7 to move forward, the lower end of the vertical rod 15 moves in the guide groove 201 at this time. The groove 201 is inclined, so that the vertical rod 15 drives the connecting column 151 to move inward on the outside of the horizontal rod 152. At this time, the connecting column 151 drives the self-positioning rod 9 to move inward. At this time, the two symmetrically arranged self-positioning rods 9 move forward and inward at the same time, so that the two self-positioning rods 9 can push the two side surfaces of the hardware accessories placed on the concave template 2 inward to limit the position, thereby ensuring that the center of the hardware accessories placed on the concave template 2 is on the same vertical line as the center of the upper punch 5, and then it is convenient to ensure the accuracy of the stamping position of the upper punch 5 on the hardware accessories, avoid the stamping position offset and cause the stamped hardware accessories to be unqualified, thereby improving the qualified rate and quality of the hardware accessories after stamping.

[0067] Embodiment 3: The self-release mode stamping die for hardware accessories processing in this embodiment discloses another structure of the lifting control assembly, so that the lower punch 13 can be automatically driven to perform the stamping operation without the need for an additional power source. Figure 11-Figure 12 As shown, a sub-regulating block 111 is installed at the lower end of the main regulating block 11, and there is a gap between the sub-regulating block 111 and the protrusion 10. The lifting control assembly includes a pushing plate 18 installed in a groove opened in the middle of the concave template 2. A rotating rod 19 is installed through the outer side of the pushing plate 18. Both ends of the rotating rod 19 are rotatably connected to the inside of the concave template 2. A second vortex spring 20 is connected to the outer key of one end of the rotating rod 19. The rear end of the pushing plate 18 passes through the rear side of the concave template 2, and the front end of the pushing plate 18 is arranged below the lower punch 13. The lower part of the lower punch 13 is connected to the inside of the concave template 2 through a reset spring 21. The sub-regulating block 111 is arranged above the rear end of the pushing plate 18, and the pushing plate 18 forms a rotating structure through the sub-regulating block 111.

[0068] On the basis of Example 1, when the upper punch 5 continues to descend and contacts the upper surface of the hardware accessories below, the main control block 11 continues to drive the sub-control block 111 to descend together. At this time, the lower end of the sub-control block 111 contacts the rear end of the push plate 18 in the lifting control assembly, and then the upper punch 5 continues to descend to punch the hardware accessories. At this time, the sub-control block 111 continues to descend and applies a downward thrust to the rear end of the push plate 18. At this time, the push plate 18 rotates with the rotating rod 19 as the center of the circle. At this time, the second vortex spring 20 accumulates force, and at the same time, the front end of the push plate 18 applies an upward thrust to the lower punch 13. At this time, the lower punch 13 moves upward to punch the hardware accessories, and at the same time, the lower punch 13 pulls the reset spring 21 to accumulate force when it moves upward.

[0069] When the upper punch 5 and the lower punch 13 cooperate to complete the stamping of the hardware accessories, the upper punch 5 moves upward, and the auxiliary control block 111 moves upward, and then the second vortex spring 20 automatically drives the rotating rod 19 and the push plate 18 to rotate in the opposite direction and reset through the stored force of the reset spring 21. At this time, the lower punch 13 is automatically driven downward to the groove in the concave mold plate 2 through the stored force of the reset spring 21, so that the highest point of the concave mold plate 2 is lower than the lowest point of the die groove 6. Then, as in Example 1, the self-demolding mechanism 8 can perform self-demolding operations on the hardware accessories in the die groove 6 after the stamping is completed, thereby completing a series of tasks.

[0070] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
