Description

Technical Field

[0001] This utility model relates to the field of pyrotechnic production equipment technology, specifically to a trolley for pressing propellant charges. Background Technology

[0002] In the field of pyrotechnics production, the pressing of propellant charges must strictly adhere to the regulations of the "Safety Technology Management for Pyrotechnics Production," with safety and efficiency being the core requirements. Existing technologies for propellant charge pressing mainly suffer from two types of deficiencies:

[0003] Traditional single-mold pressing solution: The drug column is pressed using a single mold. The process of loading the drug and loading the mold requires manual repeated picking up, putting down and dragging of the mold, which not only consumes a lot of manpower (usually requires 3 people to work together: 1 person to load the drug, 1 person to load the mold and 1 person to retrieve the drug column), but also has low production efficiency. In addition, the mold is prone to collision and generate sparks or static electricity during manual operation, which poses a great safety hazard and cannot guarantee production safety.

[0004] Customized automation equipment solutions: Some companies choose to purchase professional automation equipment to improve efficiency, but such equipment is expensive and has high subsequent maintenance and usage costs, which significantly increases the company's production costs and makes it difficult to promote and apply in small and medium-sized enterprises with limited budgets.

[0005] Therefore, there is an urgent need for a drug cartridge compression device that combines "high efficiency, low cost, and high safety" to address the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a drug cartridge pressing mold trolley, which aims to solve the problems of "low efficiency, high cost and great safety hazards" in the existing drug cartridge pressing scheme, and to achieve the drug cartridge pressing function of "high efficiency, high quality, high safety and low cost".

[0007] The technical solution of this utility model:

[0008] This utility model provides a trolley for pressing drug cartridges, including a base plate, a support, an upper template assembly, a lower top plate assembly, guide pillars, punch rods, a mold sleeve, a punch needle, and rollers. The support is vertically mounted on the upper surface of the base plate. The upper template assembly is mounted on the top of the support, and the mold sleeve is vertically fixed downward to the upper template assembly with its top end penetrating through the upper template assembly. The guide pillar is vertically fixed between the upper template assembly and the base plate, and penetrates through the lower top plate assembly, allowing the lower top plate assembly to move along the guide pillar. The punch rod is vertically fixed upward to the lower top plate assembly and cooperates with the mold sleeve to form a drug loading cavity. The punch needle is vertically mounted upward on the base plate, passes through the center hole of the punch rod, and penetrates through the mold sleeve. The rollers are mounted on the outside of the support.

[0009] According to one embodiment of the present invention, the upper template assembly includes a first upper template and a second upper template. The second upper template is vertically installed on the top of the support, and the first upper template is overlapped and installed on the second upper template. The mold sleeve is fixed between the first upper template and the second upper template.

[0010] According to one embodiment of the present invention, the first upper template has a stepped hole, the top of the mold sleeve has a limiting protrusion, the second upper template has a through hole, the mold sleeve passes through the stepped hole and the through hole, the limiting protrusion cooperates with the stepped hole for limiting, and the first upper template and the second upper template are fixed by bolts to clamp the mold sleeve.

[0011] According to one embodiment of the present invention, the lower top plate assembly includes a first lower top plate and a second lower top plate, the first lower top plate being overlapped and installed on the second lower top plate, and the punch being fixed between the first lower top plate and the second lower top plate.

[0012] According to one embodiment of the present invention, the first lower top plate is provided with a limiting hole that cooperates with the limiting ring of the punch rod, and the second lower top plate is fixed below the first lower top plate by bolts to clamp and fix the bottom end of the punch rod.

[0013] According to one embodiment of the present invention, a hook is also included, which is installed at one end between the supports and is used to pull the mold trolley to move.

[0014] According to one embodiment of the present invention, the hook is located near the bottom of the bracket.

[0015] According to one embodiment of the present invention, there are a total of eight rollers, which are symmetrically installed on the outside of two brackets, with four rollers installed on the outside of each bracket.

[0016] According to one embodiment of the present invention, it further includes a positioning post, which is vertically inserted into the corresponding holes of the first upper template and the second upper template and fixed thereon, and the bottom end of the positioning post is used to fit and position itself against the first lower top plate.

[0017] According to one embodiment of the present invention, the guide post is fitted with the through holes of the first lower top plate and the second lower top plate with a clearance fit, which is used to guide the movement of the first lower top plate and the second lower top plate.

[0018] The propellant pressing mold trolley provided by this utility model addresses the pain points of existing pyrotechnic propellant pressing technology, namely "low efficiency, high cost, significant safety hazards, and unstable quality." Through optimized structural design, it achieves multi-dimensional technological breakthroughs, with the following specific benefits:

[0019] I. Significantly improve production efficiency and reduce labor costs

[0020] Multi-mold batch pressing: By matching the punch and the mold sleeve to form multiple loading mold cavities and integrating them on the mold trolley, multiple sets of mold cavities can be simultaneously sent into the pressing position of the hydraulic press at one time. The number of drug columns pressed in a single complete stroke of the hydraulic press is significantly increased compared with the traditional single mold solution, and the production efficiency is improved by more than 300%.

[0021] Simplified single-person operation: Eliminates the tedious steps of "repeatedly loading and unloading the mold" in traditional single-mold pressing. Only one operator is needed to complete the entire process of "loading the drug - positioning the trolley - pressing - demolding - drug column recovery". No need for multiple people to cooperate (traditional single mold requires 3 people to divide the work: loading the drug, loading the mold, and recovery). Labor costs are reduced by more than 60%, while avoiding the problem of operation delays in personnel cooperation.

[0022] II. Reduce equipment and adaptation costs and improve versatility

[0023] Low-cost alternative to automated equipment: Compared to professional customized automated equipment (which usually costs hundreds of thousands of yuan), this mold trolley has a simple structure and low manufacturing cost (only 1 / 10-1 / 5 of automated equipment), and there are no high maintenance costs afterward, making it suitable for small and medium-sized pyrotechnic production enterprises with limited budgets.

[0024] Flexible adaptation to multiple specifications of propellant cartridges: For propellant cartridges of different diameters and heights, there is no need to remake the entire set of molds. Only the punch and mold sleeve that match the specifications of the propellant cartridge need to be replaced (by adjusting the outer diameter of the punch and the inner diameter of the mold sleeve to match the diameter, and adjusting the stroke of the punch to match the height). This saves the production cost of multiple sets of single molds and significantly improves the versatility of the equipment.

[0025] III. Eliminate safety hazards and ensure operational safety

[0026] Traditional single-mold pressing requires manual repeated picking up, putting down, and dragging of the mold, which can easily generate sparks or static electricity due to mold collisions, posing a safety risk of ignition of pyrotechnic materials. In this utility model, the mold sleeve, punch rod, and punch pin are all fixedly integrated on the mold carriage. There is no need for manual contact or movement of individual molds throughout the process. The carriage is moved as a whole only through the cooperation of rollers and external hydraulic cylinders, which completely avoids the problem of mold collisions and eliminates the safety hazards caused by static electricity and sparks. It fully complies with the strict requirements for operational safety in the "Safety Technology Management of Pyrotechnic Production".

[0027] IV. Improve the quality stability of the medicine column and reduce the scrap rate

[0028] Precise guidance ensures coaxiality: The guide post is vertically fixed between the upper template assembly and the base plate, and plays a precise guiding role in the movement of the lower top plate assembly, preventing the lower top plate assembly from shifting during movement; at the same time, the coaxiality error between the punch and the lower top plate assembly, and between the mold sleeve and the upper template assembly, is strictly controlled within 0.03mm, ensuring that the charging cavity is always regular, and the deviation of the charge height and weight is ≤1%;

[0029] Stable structure prevents wobbling: The brackets are symmetrically arranged and fixed perpendicularly to the base plate. There is no structural wobbling during the movement of the mold carriage or during pressing, which further ensures the consistency of the drug cartridge forming and reduces the scrap rate to below 0.5%, which is far lower than the traditional single-mold pressing (the scrap rate is usually 5%-8%).

[0030] In summary, this utility model achieves significant optimization in four core dimensions: production efficiency, cost control, safety assurance, and quality stability. It provides an efficient, economical, and safe technical solution for the pressing of explosive propellant charges, and has strong practical application value and promotion prospects.

The punch 8 is vertically mounted upward on the base plate 1, passes through the center hole of the punch 6, and penetrates through the mold sleeve 7. The rollers 9 are mounted on the outside of the support 2.

[0040] The propellant pressing mold trolley provided by this utility model addresses the pain points of existing pyrotechnic propellant pressing technology, namely "low efficiency, high cost, significant safety hazards, and unstable quality." Through optimized structural design, it achieves multi-dimensional technological breakthroughs, with the following specific benefits:

It fully complies with the strict requirements for operational safety in the "Technical Management of Pyrotechnic Production Safety".

[0049] IV. Improve the quality stability of the medicine column and reduce the scrap rate

[0050] Precise guidance ensures coaxiality: The guide post 5 is vertically fixed between the upper template assembly 3 and the base plate 1, and provides precise guidance for the movement of the lower top plate assembly 4, preventing the lower top plate assembly 4 from shifting during movement; at the same time, the coaxiality error between the punch 6 and the lower top plate assembly 4, and between the mold sleeve 7 and the upper template assembly 3, is strictly controlled within 0.03mm, ensuring that the charging cavity is always regular, and the deviation of the charge height and weight is ≤1%;

[0051] Stable structure prevents shaking: The brackets 2 are symmetrically arranged and fixed perpendicularly to the base plate 1. There is no structural shaking during the movement or pressing of the mold trolley, which further ensures the consistency of the drug column forming and reduces the scrap rate to below 0.5%, which is far lower than the traditional single mold pressing (the scrap rate is usually 5%-8%).

[0052] In summary, this utility model achieves significant optimization in four core dimensions: production efficiency, cost control, safety assurance, and quality stability. It provides an efficient, economical, and safe technical solution for the pressing of explosive propellant charges, and has strong practical application value and promotion prospects.

[0053] In this embodiment, the upper template assembly 3 includes a first upper template 31 and a second upper template 32. The second upper template 32 is vertically installed on the top of the bracket 2, and the first upper template 31 is overlapped and installed on the second upper template 32. The mold sleeve 7 is fixed between the first upper template 31 and the second upper template 32.

[0054] The first upper template 31 has a stepped hole, and the top of the mold sleeve 7 has a limiting protrusion. The second upper template 32 has a through hole, and the mold sleeve 7 passes through the stepped hole and the through hole. The limiting protrusion cooperates with the stepped hole to limit the movement. The first upper template 31 and the second upper template 32 are fixed by bolts, thereby clamping and fixing the mold sleeve 7.

[0055] The upper template assembly 3 adopts a double-layer structure design of the first upper template 31 and the second upper template 32, which are fixedly connected by bolts to form an integral load-bearing structure. Compared with the single-layer template structure, its deformation resistance is improved by more than 50%, which can effectively avoid template deformation caused by excessive force during the pressing process. The mold sleeve 7 achieves precise positioning through the cooperation of stepped holes and limiting protrusions, and is fixed by the clamping action of the first upper template 31 and the second upper template 32. Compared with the traditional single bolt fixing method, the installation coaxiality error of the mold sleeve 7 is controlled within 0.02mm, and there will be no loosening or displacement during long-term use, ensuring the dimensional stability of the drug filling mold cavity and further guaranteeing the forming accuracy of the drug column.

[0056] In this embodiment, the lower top plate assembly 4 includes a first lower top plate 41 and a second lower top plate 42. The first lower top plate 41 is overlapped and installed on the second lower top plate 42, and the punch 6 is fixed between the first lower top plate 41 and the second lower top plate 42.

[0057] The first lower top plate 41 has a limiting hole that matches the limiting ring of the punch rod 6. The second lower top plate 42 is fixed to the bottom of the first lower top plate 41 by bolts, so that the first lower top plate 41 and the second lower top plate 42 clamp and fix the bottom end of the punch rod 6.

[0058] In this embodiment, a hook 10 is also included. The hook 10 is installed at one end of the bracket 2 and is used to move the mold trolley. The hook 10 is located near the bottom of the bracket 2.

[0059] In this embodiment, a total of eight rollers 9 are provided and are symmetrically installed on the outside of the two brackets 2, with four rollers 9 installed on the outside of each bracket 2.

[0060] In this embodiment, a positioning post 11 is also included. The positioning post 11 is vertically inserted into the corresponding holes of the first upper template 31 and the second upper template 32 and fixed therein. The bottom end of the positioning post 11 is used to fit and position itself against the first lower top plate 41. The positioning post 11 is vertically inserted into the corresponding holes of the first upper template 31 and the second upper template 32 and fixed therein. Its bottom end fits and positions itself against the first lower top plate 41, forming a rigid limiting structure. This design precisely controls the upper limit position of the lower top plate assembly through mechanical hard limiting, ensuring that the relative displacement between the punch and the die sleeve remains consistent during each pressing process, thereby controlling the height error of the drug cartridge within 0.05mm. Compared with the traditional method of controlling the drug cartridge by the stroke of the hydraulic cylinder, this avoids the pressing height deviation caused by hydraulic system pressure fluctuations, significantly improves the dimensional consistency of the drug cartridges in the same batch, and reduces the scrap rate caused by height deviation.

[0061] In this embodiment, the guide post 5 is fitted with the through holes of the first lower top plate 41 and the second lower top plate 42 with clearance, which is used to guide the movement of the first lower top plate 41 and the second lower top plate 42.

[0062] Please see Figure 4 The drug cartridge pressing mold trolley of this utility model achieves efficient and safe drug cartridge pressing through modular structural design. Its working principle is as follows:

[0063] I. Initial state of the equipment: The mold trolley is placed on the special track by the rollers 9, the lower top plate assembly 4 is at the lowest position of the guide post 5 under the action of gravity, the top of the punch 6 and the bottom of the mold sleeve 7 maintain a certain distance, the top of the punch 8 is located in the center hole of the punch 6, and the whole device is in the state of waiting to be loaded.

[0064] II. Loading Process: The operator adds a measured amount of the drug to be compressed into the loading cavity formed between the punch 6 and the die sleeve 7. Since the top of the die sleeve 7 passes through the upper template assembly 3, the loading can be observed from above the upper template assembly 3 to ensure that the amount of drug loaded in each cavity is uniform.

[0065] 3. Pressing Preparation: The mold trolley is pushed by an external drive device (such as a hydraulic cylinder) and moved along the track by rollers 9 to the working position of the hydraulic press 12 to achieve precise positioning. At this time, the upper template assembly 3 is aligned with the upper pressure plate of the hydraulic press 12, and the lower top plate assembly 4 is aligned with the lower top column of the hydraulic press 12.

[0066] IV. Pressing Operation: The hydraulic press 12 starts, the upper pressure plate moves downwards and comes into close contact with the upper template assembly 3, fixing the positions of the upper template assembly 3 and the mold sleeve 7. Simultaneously, the lower ejector pin moves upwards, pushing the lower ejector plate assembly 4 to slide upwards along the guide post 5. As the lower ejector plate assembly 4 rises, the punch 6 moves upwards synchronously, squeezing the drug within the filling mold cavity upwards. Under the guidance of the guide post 5, the punch 6 and the mold sleeve 7 maintain precise fit, ensuring the drug is uniformly pressed and formed.

[0067] V. Pressure Holding and Shaping: When the punch 6 rises to the preset position, the hydraulic press 12 maintains a certain pressure to hold the pressure, ensuring the propellant is fully shaped. After the pressure holding is completed, the lower top column of the hydraulic press 12 drives the lower top plate assembly 4 and the punch 6 to return to their original positions, completing the propellant compression.

[0068] VI. Demolding of the Drug Column: After pressing is completed, the upper pressure plate of the hydraulic press 12 returns to its original position, and the external drive device moves the mold carriage out of the pressing position. At this time, the lower ejector plate assembly 4 is pushed upward again by the special pusher device, and the punch 6 pushes the drug column relative to the punch 8 to move upward, completely ejecting the drug column from the mold sleeve 7, thus realizing the automatic demolding of the drug column.

[0069] VII. Cyclic Operation: After demolding, the operator collects the propellant cartridges, and the device returns to its initial state, ready for the next round of propellant cartridge pressing. If the propellant cartridge specifications need to be changed, only the corresponding punch 6 and die sleeve 7 need to be replaced; no adjustment to the overall structure of the equipment is required.

[0070] The entire working process, through the precise coordination of mechanical structures, realizes the automated cyclic operation of drug column pressing, which not only ensures the stability of drug column quality and improves production efficiency, but also reduces operational risks through integrated design.
