Abstract
The invention relates to a stamping manufacture method and mold for a caldron, belonging to food processing equipment field, which mainly aims to solve the technical problem of adopting the caldron manufactured by stamping craft and being easy broken of the joint between the caldron body and the caldron handle in the prior art. The invention provides a stamping manufacture method and mold for the caldron capable of firm connection between the caldron body and the caldron handle. The invention adopts the technical proposal that: the stamping mold for the caldron comprises an upper mold and a lower mold; wherein, the lower mold comprises a variable pressure section and a fixed pressure section, and a hydraulic cylinder is connected with the lower part of the variable pressure section.
Description
Technical field
The present invention relates to the food processing equipment field, especially relate to a kind of method of preparing frying pan extrusion and mould thereof.
Background technology
The frying pan that uses in the general hotel, simple in structure, it basic composition is pot body and handle, in order to save manufacturing cost, adopt the Sheet Metal Forming Technology manufacturing, but Sheet Metal Forming Technology has many shortcomings more; For the junction of pot body and panhandle, be easy to make its fracture because pressure distribution is unbalanced; Even qualified finished product, the junction of its pot body and panhandle is very easy to fracture in use because produced internal stress during punching press.
As the domestic patent No. is the formula electric frying pan of the multiple end of CN00267211.1, the patent No. is the heat insulation frying pan handle of sealing monoblock type of CN99237256.9 in also having, all adopted Sheet Metal Forming Technology in its technology, but with regard to its technique effect, and the problem of the junction easy fracture of unresolved pot body and panhandle.
If reinforce the junction of pot body and panhandle by increasing material, scheme is feasible, and its effect is also comparatively desirable, but cost will improve greatly, and production and use are also very inconvenient.
Summary of the invention
The present invention solves the frying pan that existing in prior technology uses punch forming process to make, the technical problem of the junction easy fracture of pot body and panhandle etc.; A kind of method of preparing frying pan extrusion and mould thereof that pot body and panhandle firmly are connected is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the frying pan extrusion mould, comprise upper die and lower die, and counterdie is made up of variable pressure section and fixation pressure section, and the variable pressure pars infrasegmentalis connects hydraulic cylinder A.Change originally monoblock type counterdie into segmented, make the difference that is distributed with of pressure, the variable pressure section is controlled the variation of its pressure by hydraulic cylinder, the panhandle of frying pan is stressed big in early stage, stressed then reduction gradually, thereby the panhandle and the internal stress of pot body junction are reduced, and panhandle will become firm with pot being connected of body.
As preferably, there is joint pin to be connected between described hydraulic cylinder and the variable pressure section; By the connection of joint pin, make the rationally distributed of hydraulic cylinder.
As preferably, described fixation pressure pars infrasegmentalis connects hydraulic cylinder B; Hydraulic cylinder herein plays the effect of buffering, makes fixation pressure section probability with the compressive strain of pot body when stressed in order to reduce.
As preferably, be connected by support column between described fixation pressure section and the hydraulic cylinder B; By the connection of support column, make that hydraulic cylinder B's is rationally distributed.
As preferably, described fixation pressure pars infrasegmentalis connects supporter, and supporter is fixed on base plate top; The shape of supporter and counterdie fixation pressure section match, and are shaped as the shape of pot body.
Utilize above mould to adopt Sheet Metal Forming Technology to make the method for frying pan: patrix and counterdie step up sheet material, pressing equipment is exerted pressure to patrix, counterdie is to upper support, to plate stamping the time, the variable pressure section of counterdie is subjected to the adjusting of hydraulic cylinder, in the process that moves downward, act on the changeable pressure on the sheet material; Begin to the whole process that finishes from punching press, the stressing conditions at sheet material panhandle place is first big after small, is the trend that reduces gradually.
As preferably, counterdie is provided with the fixation pressure section that regulated by hydraulic cylinder B, in the process that moves downward, acts on the constant pressure on the sheet material; The hydraulic cylinder B that is connected and fixed pressure stage plays the effect of cushioning effect power, and the size that acts on the active force on the sheet material is identical all the time, makes pot shape not yielding in punching course.
Therefore, the present invention has following advantage: frying pan extrusion mfg. moulding die compact conformation, rationally distributed, adopt this mould can produce frying pan with low cost, the frying pan that uses method of the present invention to produce, internal stress is little, and panhandle and pot body junction be easy fracture not during fabrication, and also can keep not yielding in use and fracture, prolong the service life of pot.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment 1:
As Fig. 1, Fig. 2, shown in Figure 3, the frying pan extrusion mould comprises upper die and lower die, and counterdie is made up of variable pressure section and fixation pressure section, and the variable pressure pars infrasegmentalis connects hydraulic cylinder A.Change originally monoblock type counterdie into segmented, make the difference that is distributed with of pressure, the variable pressure section is controlled the variation of its pressure by hydraulic cylinder A, the panhandle of frying pan is stressed big in early stage, stressed then reduction gradually, thereby the panhandle and the internal stress of pot body junction are reduced, and panhandle will become firm with pot being connected of body; There is joint pin to be connected between hydraulic cylinder A and the variable pressure section; The fixation pressure pars infrasegmentalis connects hydraulic cylinder B; Hydraulic cylinder B herein plays the effect of buffering, makes fixation pressure section probability with the compressive strain of pot body when stressed in order to reduce; Be connected by support column between fixation pressure section and the hydraulic cylinder B; The fixation pressure pars infrasegmentalis connects supporter, and supporter is fixed on base plate top.
During use, patrix and counterdie step up sheet material, and pressing equipment is exerted pressure to patrix, and counterdie is to upper support, and to plate stamping the time, the variable pressure section of counterdie is subjected to the adjusting of hydraulic cylinder, in the process that moves downward, acts on the changeable pressure on the sheet material; Begin to the whole process that finishes from punching press, sheet material panhandle place is subjected to the adjustment of hydraulic cylinder, and the stressing conditions at sheet material panhandle place is first big after small, is the trend that reduces gradually.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technical staff of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as variable pressure section 1, joint pin 2, base plate 3, hydraulic cylinder A4, hydraulic cylinder B5, support column 6, counterdie 7, supporter 8, fixation pressure section 9, sheet material 10, patrix 11 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
