Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This present invention relates to a cutting shield machine, and more specifically to a cutting shield machine cutting iron shells of connectors from a metal strip. 
   2. The Related Art 
   Conventionally, an iron shell of a connector is generally stamped from a metal strip by a mold. In order to plate, the iron shell is stamped and connected with the metal strip still, by this, the iron shell is plated conveniently in a plating apparatus. A breaking groove is arranged between the iron shell and the metal strip. To assemble an iron shell into a connector, a worker needs to bend the iron shell and separate the iron shell from the metal strip by the breaking groove. The productivity is increased by the breaking groove between the iron shell and the metal strip, but the iron shell is fetched from the metal strip by hand, therefore, the iron shell is easy to deform by hand. 
   SUMMARY OF THE INVENTION 
   An object of the invention is to provide a cutting shield machine cutting iron shells form a metal strip. The cutting shield machine includes a worktable, a separation apparatus fixed in the worktable, a carrying apparatus delivering the metal strip into the separation apparatus, a receiving box receiving the iron shells separating from the metal strip, a crossing apparatus rolling up the metal strip without the iron shell, and a driving apparatus driving the crossing apparatus to rotate. The separation apparatus has a prop stand installed on the worktable, a rotating portion with a columned portion capable of rotation and a pole are fixed in the prop stand in sequence in the transmission direction of the metal strip. The metal strip passes from the top of the rotating portion and the bottom of the pole or from the bottom of the rotating portion and the bottom of the pole. 
   Just as the above description, the cutting shield machine separates the iron shells from the metal strip by the top of the rotating portion and the bottom of the pole or the bottom of the rotating portion and the top of pole, which replaces the manpower method, improves the working efficiency greatly, reduces the bad rate of the products, and lighten worker&#39;s labor intensity, therefore the large-scale production is easily realized.

The rotating portion  32  has a firming axle  321 , a rolling wheel  322  encircling the middle of the firming axle  321 , and a plurality of steel balls  323  arranged between the firming axle  321  and the rolling wheel  322 . Two ends of the firming axle  321  are fixed in the shaft holes  3141 . For the steel balls  323 , the rolling wheel  322  can rotate freely around the firming axle  321 . 
   The pole  33  has a bar shape. The pole  33  is arranged in the prop stand  31 , two ends of the pole  33  are fixed in the pole holes  3142 . One side of the pole  33  facing to the entrance  3121  is a plane, the other side of the pole  33  facing to the exit  3131  is a curved surface. 
   Referring to  FIGS. 1 and 5 , the receiving box  40  has a parallel box shape. The receiving box  40  includes two side walls  41 , a front wall  42  and a rear wall  43 . The front of the front wall  42  slants outward to form an accepting mouth  421 . The receiving box  40  is fixed below the separation apparatus  30 . The accepted mouth  421  stretches out of the working board  11 , the other part of the receiving box  40  is below the working board  11 . Two sides of the bottom of the receiving box  40  are arranged on the crossing bars  13 . 
   Referring to  FIGS. 1 and 7 , the crossing apparatus  50  mainly includes two round boards  51 . An axis sleeve  52  extends from the middle of the round boards  51 . A screw hole  521  is opened in the axis sleeve  52 . The round boards  51  are arranged in one side of the working board  11 . The space between the round boards  51  is level with the exit  3131  of the separation apparatus  30  and the space between the inner firming block  214  and the outer firming block  215 . 
   Please refer to  FIGS. 1 ,  6  and  7 , the driving apparatus  60  includes a motor  61 , a control box  62  and a cable  63 . The motor  61  has a main motor  611 , a rotating axis  612  assembled in the main motor  611 , and a base  613  covered on the rotating axis  612  and fixed with the main motor  611 . A plurality of screw holes  6131  are opened on the base  613 . Some screws pass through the screw holes  6131  and fix the motor  61  on the working board  11 . The rotating axis  612  passes through the base  613  and inserts into the axis sleeve  52 . A screw is inserted into the screw hole  521 , therefore, the round boards  51  are fixed together with the rotating axis  612 . The control box  62  is used for controlling the rotate speed of the driving apparatus  60  and switching the driving apparatus  60 . The cable  63  connects the control box  62  with a power (not shown), so the motor  61  can drives the crossing apparatus  50  by the rotating axis  612 . 
   Referring to  FIG. 8 , a metal strip  70  has a plurality of rectangle frames  71  connecting together. In this embodiment, only one rectangle frame  71  is shown. An iron shell  72  is stamped in the rectangle frame  71 . At least one connecting portion  711  is formed between the iron shell  72  and the rectangle frame  71 . A breaking groove  7111  is opened between the iron shell  72  and the connecting portion  711 . The metal strip  70  is settled on the shaft  213  and between the inner firming block  214  and the outer firming block  215 , and the metal strip  70  passes through the entrance  3121  and the exit  3131 , then the metal strip  70  is rolled around the axis sleeve  52  between the two round boards  51 . The metal strip  70  between the entrance  3121  and the exit  3131  presses the top of the rolling wheel  322  and the bottom of the pole  33 . 
   Referring to  FIGS. 1 to 8 , while the driving apparatus  60  driving, the motor  61  drives the crossing apparatus  50  by the rotating axis  612 . The crossing apparatus  50  rolls up the metal strip  70  to drive the metal strip  70  to move forward ceaselessly. While the metal strip  70  moving forward, the bottom surface of the metal strip  70  contacts with the top of the rolling wheel  322  of the rotating portion  32 , the top surface of the metal strip  70  contacts with the bottom of the pole  33 , so the metal strip  70  leans between the rotating portion  32  and the pole  33 , further more the pole  33  pushes the iron shell  72 , therefore, the iron shell  72  is separated from the metal strip  70 . The iron shell  72  separated from the metal strip  70  drops into the receiving box  40 . The rectangle frames  71  moves forward and is output from the exit  3131 , the rectangle frames  71  wind around the rotating axis  612  between the two round boards  51 . While all iron shells  72  separates from the metal strip  70 , the control box  62  cuts off the power, the cutting shield machine  100  stops. 
   While the cutting shield machine  100  separates the iron shells  72  from the metal strip  70 , the following ways can be used: the top surface of the metal strip  70  contacts with the bottom of the rolling wheel  322  of the rotating portion  32 , the bottom surface of the metal strip  70  contacts with the top of the pole  33 , so the metal strip  70  leans between the rotating portion  32  and the pole  33 , further more the pole  33  pushes the iron shell  72 , the iron shell  72  is separated from the metal strip  70 . 
   The rotating portion  32  may be only a columned bar, the two ends of the rotating portion  32  are fixed in the two side walls  314 , the pole  33  and the rotating portion  32  contacts the metal strip  70  as the above-mentioned methods, then the iron shells  72  can be separated from the metal strip  70  too. 
   By the above description, the pole  33  and the rotating portion  32  contacts the metal strip  70  as the above-mentioned methods, then the iron shells  72  are separated from the metal strip  70  easily, so the invention is instead of the handwork, improves working efficiency greatly, and reduces the bad rate of the products and person&#39;s labor intensity, therefore the large-scale production is easily realized.
