As shown in the attached

drawings

2 and 3, the utility model discloses tray production frock comprises upper and lower frock two parts, and upper fixture includes top-down fixed connection's upper plate 9, upper padding plate 10, an upper fixed plate 12 and die board 13, inserts the round pin 11 that punches a hole at die board 13 center, and this round pin 11 that punches a hole is fixed by fixed plate 12, and is perpendicular downwards. And guide sleeves 8 are respectively and fixedly arranged at four corners of the upper bottom plate 9.

The lower tool comprises a lower bottom plate 1, a lower backing plate 2 and a lower fixing plate 3 which are fixedly connected from bottom to top, a material cutting plate 4 is fixedly installed at the front part of the lower fixing plate 3, and a limiting plate 6 is fixedly installed above the material cutting plate 4, as shown in the attached drawing 3, a cavity formed by the material cutting plate 4 and the limiting plate 6 just meets the size requirement and the feeding requirement of a steel strip 5, and the up-down and left-right displacement of the steel strip is limited. Referring to the attached figure 2, a lower mold column 18 with a hollow structure is designed in the middle of the lower fixing plate 3 at the rear part of the blanking plate 4, the lower mold column 18 is vertically and fixedly connected with the lower fixing plate 3, and a hole in the middle of the lower fixing plate corresponds to the blanking hole 19 of the lower base plate 1. Lower bolster 15 is located the rear portion of flitch 4, and adjacent flitch 4, the fore-and-aft distance between the two is not more than 2mm, and lower bolster 15 adopts four springs 17 to support, and the position of

lower bolster

15 and 3 installation springs 17 of bottom plate all processes into the notch form, and the spring 17 of being convenient for pushes down the back, and

lower bolster

15 and 3 face contact of bottom plate guarantee the even of stamping workpiece atress. The lower template 15 is in threaded connection with the lower fixing plate 3 through the limit screw 23, and before the use, the limit screw 23 is adjusted, so that the lower template 15 and the blanking plate 4 are equal in height, the design position of the limit screw 23 cannot influence the stamping operation of the semi-finished tray product, that is, the design position of the limit screw 23 is outside the stamping operation area. The center of the lower template 15 penetrates through the lower mold column casing 18, and the limiting screws 23 and the springs 17 are uniformly distributed around the lower mold column casing 18, as shown in figure 4. When the lower die plate 15 moves up and down, the lower die column sleeve 18 plays a role in positioning and guiding the movement of the lower die plate 15, meanwhile, the limit screws 23 protrude from the holes, and in order to ensure that the protruding limit screws 23 do not influence the stamping work, notches 24 matched with the protruding limit screws 23 need to be processed on the concave die plate 13. If the design position of the limit screw 23 is reasonable and the protrusion does not affect the downward pressing of the cavity plate 13, the notch 24 can not be processed on the cavity plate 13. A support I16 is installed behind the lower backing plate 2, the support I16 is fixedly connected with the lower bottom plate 1, a positioning block 14 is fixedly installed on the support I16 at the position with the same height as the steel strip 5, and the positioning block 14 is used for positioning the steel strip in the front-back direction. Referring to the attached drawing 3, a support II 22 is installed on the right side of the lower base plate 1, the support II 22 is fixedly connected with the lower base plate 1, an air cylinder 21 is installed on the support II 22, the height of the air cylinder 21 corresponds to the position of the semi-finished tray product 20, and the semi-finished tray product 20 can be quickly pushed out and discharged through the movement of the air cylinder 21. The four corners of the lower bottom plate 1 are fixedly connected with guide rods 7, and the guide rods 7 are matched with the guide sleeves 8 and are corresponding in position.

Before the tool is used, an upper tool and a lower tool are connected with a guide sleeve 8 through guide rods 7, whether the matching size and the matching position of the upper template and the lower template meet requirements or not is checked, the upper bottom plate 9 and the lower bottom plate 1 are fixedly connected with an upper workbench and a lower workbench of a punch press, and the limiting screws 23 are adjusted, so that the lower template 15 and the blanking plate 4 are equal in height. During production, the steel strip 5 is inserted into a cavity formed by the material cutting plate 4 and the limiting plate 6 by the feeding machine, the feeding machine stops when contacting the positioning block 14, the upper tool descends, and the guide sleeve 8 and the guide column 7 guarantee the verticality of the descending direction. When the lower surface of the cavity plate 13 contacts the steel strip 5, the relative movement with the blanking plate 4 shears the steel strip to be blanked. The concave die plate 13 presses the lower die plate 15 to move downwards, the spring 17 contracts, the punching pin 11 punches a hole, and waste materials fall into a waste bin from a middle hole and a blanking hole 19 of the lower die column barrel 18. The concave template 13 continues to press the lower template 15 downwards to move, the lower die column sleeve 18 plays a role in guiding, the steel plate gradually changes in the concave template 13 to form a semi-finished product 20, and when the lower template 15 is in contact with the lower fixing plate 3, the semi-finished product 5 of the tray is subjected to punch forming. Then the concave mould plate 13 moves upwards, the lower mould plate 15 is pushed upwards by the spring 17 to the limit position of the limit screw 23, namely, the height of the lower mould plate is equal to that of the blanking plate 4, the right cylinder 21 acts to push the semi-finished product 20 out from the left side, and the cylinder retracts to complete one-time stamping. Then the feeding machine reinserts the steel strip 5 into the cavity formed by the material cutting plate 4 and the limiting plate 6, and the next punching cycle is carried out.

The workshop inconvenient for providing compressed air can be free of installing the air cylinder 20, and the blanking can be manually pushed out, so that the production efficiency is inevitably reduced as the safety production is ensured.

The downward movement of the lower template 15 is positioned and guided by the lower die column sleeve 18, and as long as the springs 17 can be completely retracted into the grooves of the lower fixing plate 3, the grooves for mounting the springs 17 are not processed on the lower surface of the lower template 15. The number of the springs 17 can be 3-8, and the springs are only required to be uniformly distributed around the lower die column sleeve 18, and four springs are preferred in the embodiment.

The upper backing plate 10 and the lower backing plate 2 are only used for adjusting the height of the tool and are unnecessary components in cooperation with the stroke of the punching machine.

The tool is additionally provided with the detector, automatic production can be realized, the detector is additionally arranged on the support I16, the steel belt positioning condition and the semi-finished product blanking condition are detected, and after the steel belt is positioned, the punching machine acts, the concave template 13 moves downwards, and the material is cut and punched and formed. After a punching operation is completed, the cavity plate 13 is raised to the highest position, and the punching operation is stopped. And then the cylinder acts to withdraw the semi-finished product, the detector detects the blanking of the semi-finished product, the feeding machine is started to feed, the feeding machine stops after the detection of the positioning of the steel strip, and the stamping motor is started to stamp. The reciprocating circulation can greatly improve the production efficiency, fully automatically operate and reduce the probability of safety accidents.

This frock reduces the semi-manufactured goods's of tray stamping production into a process by two processes, has saved semi-manufactured goods's transportation moreover, has not only improved production efficiency, has still reduced manufacturing cost.
